"IMPROVEMENTS IN MACHINERY FOR PRINTING ON BOTH SIDES OF A MOVING WEB,
FOR CUTTING THE WEB INTO LENGTHS OR SHEETS, AND FOR COLLECTING, FOLDING,
COUNTING AND DELIVERING SUCH SHEETS AS A FOLDED PRODUCT"
[Communi-
cated to him from abroad by Messieurs R Hoe and Company of the City and State
of New York, United States of America]
The invention comprises novel devices and combinations for printing cutting
and folding paper-or other fabrics and is particularly applicable to the rapid
production of newspapers or other periodicals, and has for its object the production
of such periodicals (from a roll or web of paper) in a variety of forms with greater
rapidity, and at less cost than heretofore.
It is adapted to print upon both sides of a web of paper from type or one set of
formes, secured to the periphery of one type cylinder and arranged thereon
circumferently, one form following the other, and to print upon such web different
matter upon each side thereof.
The invention also embraces a mechanism for severing the printed web into
whole sheets, and for imparting thereto two parallel folds, the same mechanism

page_text: being also adapted to sever the printed web into half sheets, impart a single
transverse fold to each half sheet, and associate such severed and folded sheets
together so that they may be piled by the same mechanism which piles the whole
sheets.
The invention also embraces mechanism for severing sheets from a printed web
and associating or collecting such sheets successively one upon the other to form a
signature."
"
The invention also embraces a mechanism for counting, by printing upon the
margin of one of a predetermined number of sheets.
The invention also embraces a mechanism for imparting the final folds to a
sheet and sealing the same within a wrapper.
The invention also embraces a mechanisin for laying or piling the printed sheets
open or flat; Also a modification particularly adapted to arrest and pile once-
folded sheets.
Also a modification particularly adapted to arrest and pile sheets having two or
more folds, and a modification of the same.
The first part of the invention relates to the printing mechanism which
comprises a single central type-carrying cylinder, of sufficient diameter to enable the
type formes to he secured thereon circumferentially, and also provide between such
formes or set of formes a proper inking space for distribution. Two series or
groups of impression cylinders are arranged about the circumference of the type
cylinder, so as to be driven in unison therewith. A web turner is located between
said series of impression cylinders so as to receive the web of paper as it passes
from the first series, reverse it and direct the same to the second series of
impression cylinders. For the purpose of illustration it is assumed that the
circumference of the type cylinder is equal in length to that of six of the type
formes, and that but two-thirds of its circumference is occupied by such type
'formes, the remaining one-third serving as the ink distributing surface. In this
case each group of impression cylinders comprises three each, making a total of six
impression cylinders.-These cylinders may be in diameter equal to one half that
of the type cylinder, and have at least a one third part of their peripheries
depressed or cut away so as to cause that portion to be out of printing contact
with the type cylinder; or these impression cylinders may be of any convenient
Bize, and be supported in bearings suitably connected with cams, so that said
impression cylinders may be moved into and out of printing contact with the type
cylinder for the following purpose, i.e., so that as a one half portion of the type
formes, as for instance pages 2-3,-pass under the first series of impression
cylinders, the paper shall be printed therefrom, while the remaining one half
portion of type formes, or pages 1.-4,--shall pass such first series of impression
cylinders without being brought into printing contact therewith. By this action
the entire surface of one side of the web will be printed from one set of formes.
The web thus printed upon one of its surfaces is then conducted over the web
turner, by which it is reversed, and is then led to the second series of impression
cylinders, its unprinted side being by them presented to the type cylinder. These
cylinders are, like the first series, provided with depressed portions, or are moved
to and from printing contact with the type cylinder, so that as the remaining
half portion of the type formes, or pages 1-4, pass under them, they will be
brought into printing contact therewith, and thus the remaining or opposite side of
the web will be entirely printed by passing over the last series of impression
cylinders. That portion of the type formes, as for instance pages 2-3, which
acted in printing contact with the first series of impression cylinders, pass the
second series without printing contact therewith. The inking devices may be of
the ordinary construction, ink distributing rolls being located between each
impression cylinder so as to properly ink the formes after each impression.
Adjusting rolls are also located between each impression cylinder, over which the
web of paper is carried as it passes from one impression cylinder to the other, and
by which the proper is maintained. The impression cylinders may run in fixed

page_text: bearings, and the type formes be connected with suitable devices, whereby one set,
as pages 1-4, are withdrawn from printing contact as they pass the first series of
impression cylinders, and moved outwardly so as to be in printing contact with the
second series of impression cylinders when passing the second set of formes, as
pages 2-3.
By this mechanism, and the operation just described, it will be seen that the
outside pages of each signature will be printed upon one and the same side of the
web.
The second part of the invention comprises a transverse severing and folding
mechanism capacitated to sever the web into four paged sheets, and impart two
parallel folds thereto, or to sever the web into half or two paged sheets, and impart
one transverse fold to each.
When a
As the
This mechanism comprises two cylinders, each of which is provided with
members of a web severing, web controlling, and web folding devices.
four paged sheet is to be produced, the leading end of the printed web is impaled
upon projecting pins, which are located near the cutting edge of the first cylinder,
and is carried thereby around upon its surface, until the folding blade (which is
also carried by said cylinder, and located at a point thereon opposite the impaling
points,) is nearly opposite co-acting folding rolls, when the points are withdrawn
and the paper is folded along its centre between the aforesaid folding rolls. As the
cylinder continues to revolve, the points are again projected through the overlying
web, and the severing knife carried by this or the second cylinder is brought into
contact with a co-acting groove carried by the opposite cylinder, and the web
severed just in advance of the points carried by the first cylinder, and upon which
the leading end of the web is now again impaled. As the folded sheet issues from
between the first pair of folding rolls, it is carried by tapes (which pass around
one of such rolls to the surface of the second cylinder around one of the folding
rolls belonging to such second cylinder, and returned to the first cylinder or its
folding roll) to the surface of the second cylinder. This cylinder is also provided
with impaling points and a folding blade; the points are so positioned as to receive
or penetrate the forward end of the once folded sheet while the folding blade will
meet the sheet at a point equidistant between its forward and rear ends.
folding blade of this second cylinder approaches its co-acting folding rolls, it is
projected so as to enter the fold line of the paper between said rolls the impaling
points or other web controlling device being withdrawn at the proper time to
permit the paper passing from the cylinder in the usual manner. It will be found
that excepting the paper be very fragile and moist, the second cylinder may be
operated successfully to impart a second fold to the once folded sheet without the
aid of web controlling devices. The sheet having received its second transverse
fold, may pass to other folding devices, and receive additional cross folds, and
folded within a wrapper for mailing purposes, or may pass directly to a piling
device, all of which will be hereinafter more fully referred to. When it is desired
to produce half or two paged sheets, the first and second cylinders are, by moving
one of them on its axis independently of the other, changed as to their first
relation to each other. The first cylinder is provided with two additional cutting
devices or grooves, the cutting device of the second cylinder used in the first
instance, being now, by this change, made to align with one of the new cutting
members of the first cylinder, and an extra cutting device is secured to the second
cylinder at a point diametrically opposite the first mentioned cutting device; the
folding blade of this second cylinder thus occupies a position upon one side thereof
at a point equidistant from the cutting devices. By this change the central and
the end margins of a four-paged sheet will be brought respectively each over a
cutting device; that cutting device of the second cylinder which is in advance of
the folding blade thereon is provided with impaling points or other web controlling
devices, which are actuated by an adjustable cam secured to the frame work.
the cylinders are rotated, the first cylinder having the leading end of the web
impaled upon its points, carries the same onward until the centre margin of the
As

page_text: full sheet is brought under the action of the swing devices of said cylinders, when
the new leading end of the freshly severed web is (simultaneously with this
severing of the first half sheet) impaled upon points carried by the second cylinder,
around which it is now carried, while the first half sheet is also carried by the
points of the first cylinder, until it is centrally folded by the folding blade of the
first cylinder, as in the case first mentioned. This folded sheet is now, by means
of the tapes, brought into contact with the second cylinder at a point (upon the
outside of the sheet carried by such cylinder) just in the rear of the edge of its
folding blade. The second series of cutting devices being now brought into action,
severs from the web the sheet carried by the second cylinder, the new leading end
of the web being at this time impaled upon the points of the first cylinder.
the folding blade of the second cylinder reaches its folding rolls, it is turned so as
to enter the bight of the overlying sheet between them.
As
This action causes the folded sheet which was received from the first cylinder to
accompany the sheet folded from the second cylinder between the same folding
rolls; thus the two half sheets, each having one transverse fold, pass simultaneously
between the second pair of folding rolls.
The foregoing relates particularly to a mechanism designed to manipulate four
paged or two paged sheets only, but when it is desired to manipulate a printed
web so as to produce a two or a four or an eight paged signature, the first and
second cylinders last described may have their cutting members removed, their
diameters being increased so as to provide a working space between the sheets,
when received upon their peripheries, and grippers substituted for the impaling
points. In this case the printed web will pass between cutting cylinders, which
partially sever it into whole or half sheets, as the case may be, the partially severed
web passing between accelerated tapes and rolls, which complete the severance of
the sheets which are then received by the grippers of the first and second cylinders,
their grippers performing the same function as the points already described.
When it is desired to produce an eight paged product in addition to a two paged
and a four paged signature, a collecting mechanism of the following character is
placed between the cutting cylinders and the folding cylinders, and constitutes the
third part of the invention.
This part of the invention comprises the cylinders for partially severing the web,
the printed web, together with accelerated tapes and rollers, by which the web is
severed into sheets, having a space between them, all of which is of the usual
construction. These sheets are then, by means of a switch, directed alternately
into two paths of travel consisting of moving tapes and leading rolls.
These paths may be of equal length; the carrying tapes constituting both paths of
travel, may move at the same speed as those which receive the sheets from the cutting
cylinders. The first path of travel carries its sheet direct to the common exit, while
the second path of travel is composed of carrying tapes moving at a like speed, but
having their path intersected by a pair of slow speeded rolls having a portion of
their surfaces cut away. These rolls are so positioned as to permit the incoming
sheet to pass between them until it has arrived at the proper place, where the full
portion of the rolls bites upon the sheet, retarding and reducing its speed to that of
said rolls, (the carrying tapes being sufficiently apart to avoid crumpling the sheet).
These slow speeded rolls carry the sheet forward slowly until the succeeding sheet,
which was directed by the switch into the first path of travel, has overtaken, and is
in register with the aforesaid retarded sheet. At this time the cut away portions
of the slow speeded rolls are opposite each other when the sheet is released and
passes on at the same rate of speed as the first sheet, and as the two paths of travel
converge to one single path, the two sheets are therein brought together in proper
register one upon the other, whence they pass on to the folding cylinders. Instead
of retarding the sheet to cause it to be overtaken by the second sheet, it may be
accelerated so as to overtake the preceding one. The slow speeded cut away rolls
may be supplanted by any other suitable device for retarding the sheet.

page_text: This
The next part of the invention relates to mechanism for laying or flying the
open sheet. As it will be understood when it is desired to deliver open or unfolded
sheets by the last mentioned delivery mechanism, the switch may be secured in
position so as to cause all the sheets to pass over the first path of travel and thence
to the fly band or receiving tapes. This mechanism comprises two cylinders one of
which is provided with devices for receiving and controlling the leading end of the
sheet, and also with devices for throwing off the rear ends of the sheets.
cylinder is of sufficient circumferential dimensions to receive two or more sheets
upon its surface, and moves at a surface speed equal to that of the printed web or
sheet carrying tapes. The second cylinder is of much smaller diameter, and moves
at a much slower surface speed; it is also provided with three or more sets of
grippers, and is so timed as to bring one of its sets of grippers into position to act
so as to seize the rear of the sheet carried by the first cylinder, the rear lifting
fingers carried by that cylinder lifting that portion of the sheet from the cylinder,
while the forward end holding grippers are released. The sheets are then slowly
deposited upon carrying tapes, the grippers of the second cylinder releasing their
hold at the proper time.
Another part of the invention relates to a modification of the last described
mechanism, and consists of devices by which open or unfolded sheets are piled one
upon the other, and is accomplished by devices which operate to arrest the forward
movement and retain the leading end of the sheet until the same is removed and
stripped from its carrier, and consists of two cylinders, one of which receives the
sheet from the carrying tapes, and carries it forward on its surface by means of
grippers or other retaining devices, and moves at a surface speed equal to that of
the carrying tapes. A second cylinder of smaller dimensions moving at a slower
surface speed, and provided with two or more sets of grippers, co-operates with the
first sheet carrying cylinder. As the first cylinder, with the open sheet upon its
surface, its leading end under control of grippers or other devices, advances, the
grippers of the second cylinder are so positioned as to engage with the leading end
of the sheet which is "signed" thereby, and as the first cylinder advances, the
sheet is turned over the second cylinder, which retains the forward end of the
sheet until the rear end is thrown out beyond the cam, the body of the sheet being
held against the surface of the first cylinder by the pressure of the atmosphere, or
by a pressure roll which is held and carried in such position as will ensure the
sheet being turned and laid without crumpling.
In some cases it may be found desirable to direct a blast of air against the sheet
so as to cause its rear end to lie out straight upon the carrying tapes or the fly
table;
the grippers on the slowly revolving cylinder or shaft then release the sheet
which has been brought to rest by the action of the same.
It will be understood that when it is desired, the sheet carrying cylinder may
be provided with cutting devices and co-acting cutting cylinders, and thus receive
the printed web directly from the printing mechanism, and which is then severed
by these cylinders into sheets of the desired dimensions.
Another part of the invention relates to mechanism by which sheets are brought
together and piled one upon the other, and is particularly adapted to the manipu-
lation of once folded sheets as they issue from the folding mechanism of a rotary
printing machine, and consists in arranging revolving or reciprocating finger
guides and slow speeded rolls in the path of travel from the folding rolls to the
receiving table, so that the forward sheet will enter between the bite of slow
speeded rolls, which move at such speed as will enable a second or a third sheet to
be within their action before the first received sheet has been freed therefrom, the
fingers being operated so as to depress the rear end of the first sheet, and thus
permit the forward end of the following sheet to pass thereon, and into the bite of
the same feeding rolls. The papers being now overlapped one upon the other,
they may be fed from the rolls upon an automatically lowered receiving table, a
stop guide being placed adjacent thereto; this stop guide may be used to prevent
the sheets from sliding off the table, their gravity causing them to stop when out

page_text: of the bite of the slow speeded rolls, or another pair of still slower speeded rolls
may be placed so as to receive the overlapped sheets as they issue from the first
pair of rolls and still further reduce their speed, and also deliver them upon slower
moving tapes instead of the table, from whence they may be taken as desired.
This last described sheet piling mechanism may be applied to the folding rolls
which impart the last folds to a sheet of paper as it passes through the folding
mechanism of a web printing machine, as, for instance, that herein described, when
it would operate to pile the two paged sheets, or the four paged sheets, or the
eight paged sheets, as they issue from the last pair of folding rollers. A modifi-
cation of this last described sheet piling mechanism consists of a slowly revolving
cylinder provided with two or more sets of grippers, in combination with a
stationary stop guide and slowly moving receiving tapes, the surface speed of the
cylinder being such as will ensure succeeding sheets to be taken upon its periphery
without overlapping each other, the grippers being of sufficient thickness, or shaped
so that their outer surfaces will pass away the rear ends of the preceding sheet
which has been released from its grippers and brought to rest against the stop
guide, or suitable projections for that purpose may be secured to the surface of said
cylinder.
A modification of the last described piling mechanism consists of a rotating
shaft provided with a series of S shaped arms placed so as to receive the sheets
as they are delivered from the last pair of folding rolls of a web printing or other
folding machine, in the curve of their ends. Slowly moving tapes receive the
sheets as they are received and piled thereon one upon the other by the S shaped
arms, a stationary guide being placed at the proper distance to permit the ends of
the S shaped arms to pass by them and leave the forward ends of the sheet against
such guide or stop. The outer surface of the arms press the rear end of the
preceding sheet away, and ensure the accurate depositing of the following sheet
thereon.
Another part of the invention relates to devices for dividing a web longitudinally,
and transferring one half upon the other, and is particularly adapted for use when
it is desired to place the axis of the transverse cutting cylinders at a right angle to
the axis of the printing cylinders, wherein it is desired to produce a six line paged
signature, when such a product is required. This part of the invention consists of
a leading roll provided with an annular groove and a co-acting cutter, and also of
a bar or turning surface consisting of two parts, which lie in the path of the printed
web, and at an angle of about 45 degrees thereto. When the product is to be a two
paged or a four paged one, the full width web passes over and around the turning
bars, which are then secured in line with each other, and by which the web is
turned to a line of travel at right angles to its first line of travel. When a six
line paged signature is desired, the formes of printing matter are arranged in the
usual manner, the full width web is divided longitudinally, and one half, preferably
the inner half of the turning bar, is carried inwardly towards the printing machine,
along a suitable frame provided therefor, until the inner half of the longitudinally
divided web, when carried around said turning bar, will lie directly under the
outer half of said web, which is carried over the outer turning bar; thus the two
webs will be imposed one upon the other, and passing over suitable register rolls,
will be acted upon by the cutting cylinders as a single web; these two ply sections
will then be associated or collected one upon the other as herein before described,
and folded together and delivered as a single product. The usual paste applying
devices will be employed when it is desired to connect the several sheets together
along their centre margins, or first line of fold.
Another part of the invention relates to devices for dividing the sheets delivered
from a printing machine into quires or lots containing predetermined quantities,
and consists of a revolving carrier provided with any suitable design which is
actuated so as to be brought into printing contact with the unprinted margin of
every tenth or twentieth sheet, or any other predetermined number. The device
may be placed at any suitable position in the path of travel of the sheets, its

page_text: printing design being caused to protrude so as to come in contact with the passing
sheet at the proper time by means of gears or cams which derive motion from any
suitable part of the printing or delivering machanism, and are so timed as to
project the printing design once during any desired predetermined number of
revolutions thereof as the case may be. The same result may be accomplished by
causing the proper passing sheet to be raised by its supporting roll, so as to be brought
into printing contact with a co-acting revolving printing plate. The design may be
secured to one of the printing cylinders, so as to be brought into contact with the
unprinted margin of a sheet once at every tenth or twentieth revolution thereof,
as the case may be. By this operation, each marked sheet will form an index of
division in the pile of delivered sheets readily distinguishable from the other sheets
in the pile.
Another part of the invention relates to devices for imparting the final folds to
a sheet of paper, and consists of three folding rolls, one of which is provided with
a folding blade, curved in cross section, and so arranged that when the papers are
to be delivered in the folded condition in which they are secured by said folding
rolls, the folding blade is rendered inoperative, and rotates with its carrier without

mechanisms operating this folding blade are of such a character that when in
operation, they will cause its folding edge to meet the paper on its fold line, and

withdrawn, or rotated in its carrier, its motion being accelerated at the time of
folding contact, so as to ensure the proper folding of the sheet, the curved form of
the blade enabling its folding edge to remain in contact with the paper a sufficient
length of time to secure this result.
Another part of the invention relates to devices by which sheets, as they issue
from a printing or folding mechanism, are folded within a wrapper and sealed
therein

The first part of the invention relates to the printing mechanism which comprises
a single central type carrying cylinder of sufficient diameter to enable the type
formes to be secured thereon circumferentially, and also provide between such
formes or set of formes a proper inking space, for distribution. Two series or

two thirds of its circumference is occupied by such type formes the remaining one
third serving as the ink distributing surface. In this case each group of impression
cylinders comprises three each, making a total of six impression cylinders. These
cylinders may be in diameter equal to one half that of the type cylinder and have
at least a one third part of their peripheries depressed or cut away so as to cause

page_text: that portion to be out of printing contact with the type cylinder, or these impres-

with. By this action the entire surface of one side of the web will be printed from
one set of formes. The web thus printed upon one of its surfaces is then conducted
over the web-turner by which it is reversed and is then led to the second series of
impression cylinders, its unprinted side being by them presented to the type
cylinder. These cylinders are like the first series provided with depressed portions
or are moved to and from printing contact with the type cylinder, so that as the

cylinder so as to properly ink the formes after each impression Adjusting rolls are
also located between each impression cylinder over which the web of paper is
carried as it passes from one impression cylinder to the other and by which the
proper register is maintained. The impression cylinders may run in fixed bearings
and the type formes be connected with suitable devices whereby one set, as pages
1-4, are withdrawn from printing contact as they pass the first series of impres-
sion cylinders, and moved outwardly so as to be in printing contact with the
second series of impression cylinders when passing through the second set of formes
as pages-2-3. By this mechanism and the operation just described it will be
seen that the pages of each signature will be printed upon one and the same side
of the web
The arrangement of printing cylinders comprised under this head of the invention
is shewn at Sheet 1. of the accompanying drawings. Figure 1. being a diagram of
a cross section of the machine and Figure 2 a diagram showing the mode on which
the web is printed.
are
X is a rolled web of paper. Z is a type cylinder and A, B, C, D, E, F,
impression cylinders arranged in two sets of three each around the type cylinder
Z-G are adjusting rolls. H is the web turner and I I are the ink distributing
rolls.
Suppose now it is intended to print a four page paper, four formes, 1, 2. 3 and 4
will be required. These formes are arranged on opposite sides of the type cylinder
in pairs 1 and 3, 2 and 4 leaving a blank equal to a sixth of the circumference of
the cylinder on both sides between the two sets of formes. These blanks are depressed
and are utilised as ink distributing surfaces.
The impression cylinders A, B, C D E F are half the size of the type cylinder
and one third of their circumference is depressed as clearly seen on the Figure for a
purpose to be presently explained.
The working of the machine is as follows, Let it be supposed that the web is
passing and the type cylinder rotating in the direction of the arrows and form 2 as
just printed at cylinder A the impression which I will term 2A, sufficient web of
paper will then pass this cylinder to forn two blank pages, the first blank being
left by reason of the depressed portion of the cylinder A coming opposite the
forme 4 which will not therefore print
The second blank is left by reason of the depressed portion of the type cylinder
coming opposite the cylinder A
The next impression will be taken from forme 3 which now comes into printing

page_text: contact with the cylinder A and which may be termed impression 3 A
there will be two blanks caused as before explained
After this
The next impression will be 2 A again and the next 3 A so that at the first
impression cylinder A first 2 A and then 3 A will be printed, leaving two blanks
between each impression to be filled up, the first with impression from forme 3 and
the second from forme 2 as will be hereafter explained.
The impression cylinders A B C are so set that their depressed portions shall
always come opposite formes 4.
Impression 2A will then pass first round an adjusting roll and then past
cylinder B by which time forme 3 will have come round. and after printing
impression 3 A on the third blank in rear of 2 A, will be in the position to print
3 B on the blank immediately succeeding 2 A.-2 A and 3B will then pass round
another adjusting roll and past Cylinder C by which time forme 2 will be opposite
Cylinder C and will print impression 2 C on the second blank in rear of 2 A and
between impressions 3 B and 3 A. It will thus be seen that as the printed web
leaves Cylinder C it will contain alternately on one side only, impressions from
formes 2 and 3 see the diagram Figure 2, such impression, having been given at the
three cylinders A B C successively. The web is now conveyed to the web turner
where it is reversed so as to bring the unprinted side uppermost ready to receive
impressions from formes 1 and 4 at the second set of impression cylinders DE F
impression 1 coming at the back of 2 and 4 of 3. The mode of working at this
set of cylinders will be practically the same as that above described with reference
to cylinders A B C, impressions 1 and 4 leaving two blanks between will be taken
alternately at Cylinder D the blanks being filled up alternately 4 and 1 and 1 and
4 at the other two cylinders E and F in the manner before explained with reference
to cylinders B and Č
When completely printed the web will pass between a pair of cutting cylinders
to be severed into sheets of the proper size for a four page paper and will then be
delivered to folding mechanism of any well known construction
It will be evident that the above described arrangement of printing machinery
may be made available for printing an eight page paper
The width of the machine will of course have to be increased so as to take two
formes side by side by which two pages will be printed on one side at one time.-
Thus the formes will be arranged in two sets of four formes each instead of two
sets of two formes each as above described.-One set of formes will contain type
for pages 2-7 and 3-6 and the other set will contain type for pages 1-8 and 4-5-
The particular positions of these formes 1, 2, 3, 4, 5 6, 7 and 8 on the type cylinder
will be readily understood by persons conversant with this class of printing
machines
The working of this machine to print an eight page paper will be the same as
above described if instead of 2 and 3 and 1 and 4 the formes be read as 2-7,-4-5,-
1-8 and 3-6. The printed web will be severed by cutting cylinders in the usual
way and before being folded longitudinally and transversely or either will be
associated by means of a device forming part of the folding mechanism shown at
the right hand of Figure 1 and to be hereafter more particularly described, or by
any other collecting or associating mechanism
The second head of this invention comprises a transverse severing and folding
mechanism capacitated to sever the web into four paged sheets and impart two
parallel folds thereto or to sever the web into half or two paged sheets and impart
one transverse fold to each.

The mechanism for perfecting the web of paper as shewn in the present case
consists of type Cylinders 1. 2 and impression cylinders 3. 4. the plates upon the
former being inked from the fountains 5. 6 through trains of distributing and form
rollers 7. 8. all of which are mounted in bearings in a suitable frame in substantially
the relative positions shown and are driven in unison in the usual manner
For convenience in placing the plates upon the Cylinders and in removing the
same, a portion of the form rollers may be mounted in swinging frames as 9. 10. so
as to be turned back as shown by the dotted lines Figure 3 Sheet II.
The web of Paper to be perfected is led from the roll 11 mounted upon a suitable
spindle located above the impression-cylinders as shown or in any other convenient
position and after passing around leading rolls as 12. 13 is printed upon one side
by passing between Cylinders 24. It passes thence around Cylinder 4 upward
between it and Cylinder 3 and then between the latter and Cylinder 1 where it is
printed upon its other side after which it passes downward around guide roll 14
to the delivery mechanism This delivery mechanisın consists principally of two
revolving carriers 15. 16 provided with engaging gears 17 18 by which they are
caused to revolve in unison motion being imparted to them from the impression-
cylinder 3 through intermediate gearing The carrier 15 is provided with two
sets of Sheet holding pins 20. 21. which are pivoted to arins 22. 23 fast to rock
shafts 24. 25. journaled upon the interior of the carrier and by the operation of
which the pins are moved in and out through perforations in the surface of the
carrier The Shafts 24. 25. are provided with collars 26. 27. (see Figures 6 and 15)
having each a recess into which extends a projection upon the disks 28. 29
respectively. These disks are mounted to turn upon studs projecting from the
ends of the Carrier and are provided with arms 30. 31. which are acted upon
by Cams and lugs as hereinafter explained, to protrude and retract the pins at
the proper times. The disks 28. 29 are provided upon that portion of their
peripheries opposite or nearly opposite to the projections just referred to with
series of notches 32. 33 in which rest at all times small projections upon the ends
of Springs 34. 35. These springs are so adjusted that while they will yield to
allow the disks to be turned when the arms 30. 31 are acted upon by the cams
and lugs they will yet securely hold the disks and consequently the pins in
whatever position they are moved to.
The disks 28. 29. instead of being provided with notches as 32. 33. may be
rovided with projecting arms as 99 (see Figure 16) the ends of which arms
re provided with notches in which rest the bowles of Spring pressed arms 100
which latter construction will usually be found preferable
The carrier 15 is also provided with a rotating folding blade 36 located at a
oint nearly opposite the pins 20 and of the ordinary construction and operated
the usual manner to fold the sheets from the carrier into the bite of the
olding rolls 37. 38. said rolls being positively driven from the gear 17 of the
arrier in the usual manner.
The carrier 16 is provided with a set of Sheet holding pins 39 which are con-
ructed in the manner already set forth in connection with pins 20. 21. Just in
Ivance of the pins 39 the carrier 16 is provided with a severing blade 40 and at a
int opposite to the blade 40 it is provided with a second severing blade 41.
be blade 40 is shown in the present case as an ordinary fixed blade while the

page_text: blade 41. is shown as provided with means for giving to it a reciprocating motion
Both blades may however be fixed or both may reciprocate At a point about half
way between the blades 40 and 41 the carrier 16 is provided with a rotating
folding blade 42 which is also of the common construction and is operated in the
usual manner to fold the sheets from the carrier 16 into the bite of the folding
rolls 43. 44. these rolls being positively driven from the gear 18 of the carrier in
the usual manner.
The carrier 15 is provided in addition to the devices already described with
.cutting grooves 49 50 and 51 the grooves 49 and 50 being located just in advance
of the pins 20 and 21 respectively and the groove 51 about half way between
pins 20 and folding blade 36.
The gear 17 by which the carrier 15 is driven is mounted loosely upon the Shaft
of the carrier and is secured to the face of a disk which is fast to the Shaft of the
carrier by bolts 53 passing through slots 54 in the gear as shown in Figures 3. 7.
and 8 By this construction the carrier 15 can be shifted with relation to the
gear 17 so that the cutting blade 40 can be made to coact with either groove 49
or 51 as may be desired When the carrier is set so that the blade 40 coacts with
groove 49 the blade 41 will as the carriers rotate come opposite to the recess in
which the folding blade 36 rests and will consequently be inoperative but when
the carrier is set so that the blade 40 coacts with groove 51 the groove 50 will be
brought into position to coact with blade 41 so that both blades will be operative.
The purpose of this arrangement will be hereinafter explained.
A series of tapes 45 pass around roll 37 between it and roll 38 under feed
roll 48 which is positively driven from gear 17 of carrier 15 and after passing
beneath carrier 16 and around roll 43 return beneath an adjustable tension roll 47
Lying above and coacting with these tapes to form a pathway for the sheets
between the roll 38 and the carrier 16 are the fixed guides 46 of the usual form.
As the folded sheets emerge from the rolls 43. 44. they will be deflected by
guides 55 so as to follow the surface of roll 43 and will pass between it and feed
roll 56 which is geared to and positively driven by roll 43. after which they will
pass downward along guides 57. Situated a suitable distance below the roll 43°
and so placed that its arms will project between guides 57 is a rotary fly or
packer 58 which is composed of a series of S shaped arms mounted upon the
shaft 59 which is rotated by gears 60. 61. so as to make one half a rotation to each
rotation of the carriers. This fly or packer properly forms a modification of the
fourth head of the invention but being shown in connection with the mechanism
above described it is included here for convenience.
Just below the fly or packer there is located a series of horizontally moving
tapes 62 upon which the folded sheets are deposited by the fly and by which they
are carried to any convenient distance from the machine. These tapes pass around
pulleys or a roll 63 and another roll or series of pulleys (not shown) and may be
moved continuously or intermittently by connection with any convenient part of
the printing or delivery mechanism. One convenient device for giving these tapes
an intermittent movement is shewn in Figure 6 in which the fly-shaft is shown as
provided with a small crank 64 the pin of which works in the slotted end of a
lever 65 which is pivoted upon the shaft of pulleys 63 so that as the fly shaft
revolves the lever will receive a vibratary movement. The lever 65 is provided
with one or more pawls 66 which engage with the teeth of a ratchet wheel 67 fast
upon the shaft of pulleys 63 and by means of which the vibrations of lever 65
impart an intermittent movement to the pulleys and tapes
The delivery apparatus just described although especially adapted to operate in
connection with a printing mechanism constructed and arranged as that herein shewn,
is yet, as will readily be understood, capable of operating successfully in connection
with any form of rotary web printing mechanism. This delivery apparatus may
be placed beneath or at one end of the printing apparatus so that the carriers will
lie parallel with the printing cylinders as shown in Figures 3 and 4 or it may be
located at one side of the printing apparatus so that the carriers will be at right

page_text: angles to the printing cylinders as shown in Figures 7 and 8
When in the latter
position which in many respects is to be preferred it will be found most convenient
to drive the carriers through gear 17 instead of gear 18 This may be done as
shown in Fegures 7 and 8 by providing said gear with a set of bevel teeth 70.
which will engage with a similar set 71 upon an intermediate 72 which is con-
nected by a second intermediate 73 with the gear 74 upon the shaft of cylinder 3.
In this latter case also the web after passing roll 14 will pass around a turner by
which it will be turned so as to be led at right angles to its previous path of
travel
The primary object of this head of the invention-ie the delivery of the printed
product in sheets having two parallel transverse folds as herein before stated
can be attained by the devices just described when the printing cylinders and the
carriers and rolls of the delivery apparatus are of a length only sufficient to operate
upon a single width web, but when it is desired that the machine shall be
capacitated to associate two sheets and deliver them with two parallel transverse
folds the printing Cylinders and the carriers and rolls of the delivery apparatus
will be of a length sufficient to operate upon a double width web which after
leaving the impression-cylinder 3 will be split into two single width webs by an
ordinary slitter 68 located as shown in Figs 4 and 8. When it is desired to deliver
the printed product in full sized or whole sheets the carrier 15 will be set so that
its groove 49 will be in position to coact with the severing blade 40 and the web
if one of double width is used will be split by the slitter. When the carriers of
the delivery apparatus lie parallel with the printing cylinders the web or the two
halves of the split web will pass directly from the roll 14 onto the carrier 15 as
shown in Figure 4. When however the carriers are set at right angles to the
printing cylinders, the web or webs after leaving the roll 14 will be conducted
around a web turner so as to be led forward at right angles to its or their previous
course of travel. Such a turner may consist simply of a bar or plate so obliquely
across the path of the web, but in the present case it is shown as composed of two
bars 75. 76 the ends of which meet at the middle of the web so as to form a
continuous turning surface as shown in Figure 8-The bar 75 is rigidly supported
in any convenient manner as by the plate 77 extending from the cross bar 78
which is securely fastened to the frame of the machine. The bar 76 is supported
upon the edge of a plate 79 having screw threaded ears 80 through which passes
the threaded rod 81 supported in bearings 82 upon the frame and having upon its
end the crank 83 by which it can be turned to move the bar and plate 76-79 to
different positions, for a purpose to be hereinafter explained. The bar and plate
76. 79 are sustained in a horizontal position by means of the rod 84, which extends
just beneath the plate as shewn in Figs 8 and 9. After passing around the turner
the web will pass upward around roll 85 on to carrier 15. As its leading end
enters the bite of the carriers 15. 16 it will be impaled upon the pins 20 which
will be protruded at that point by the lug 86 upon the carrier 16 (see Fig 5)
coming into contact with the arın 30 of the disk 28. The pins 20 having been
thus protruded will be held in that position by the spring 34 as berein before
explained and will carry the end of the web or the two ends of the split web
around upon the carrier until the blade 36 arrives in position to fold it or them
between rolls 37-38 at which time the arm 30 will come into contact with the
fixed cam 87 by which the arm will be moved so as to retract the pins and release
the end or ends of the web. When the pius 20 again arrive at the bite of the
carriers 15, 16 they will be again operated upon by the lug 86 and protruded as
before and at the same time the web will be severed by the blade 40 co-acting
with groove 49 The pins 21 and 39 will during this operation remain retracted
and idle there being no lugs upon the carriers in proper position to act upon the
arms 31 and SS to protrude them. The severing blade 41 will also remain idle for
the reason hereinbefore explained. The end or ends of the web having been folded
between rolls 37. 38 and severed from the web as described, will be carried forward
by tapes 45 until the fold line arrives at the bite of the tapes and the carrier 16,

page_text: at which time the pins 39 will have arrived at the same position (see Fig 11) and
will be protruded to impale the sheet or sheets by reason of their operating arın 88
coming into contact with the fixed cam 89. The sheet or sheets thus impaled
will pass forward upon the carrier 16 until the folding blade 42 is operated to fold
it or them between rolls 43-44 at which time the arm 88 will come into contact
with the fixed cam 90 and be moved so as to retract the pins and release the sheet
or sheets (See Fig 10) The Sheet or sheets, having thus received two parallel
transverse folds will then pass outward between rolls 43-44 and downward
between rolls 43-56 into the curve of the arms of the rotary fly 58 by which the
lower edges of the folded sheets will be carried downward and back ward against
the guides 57 while the opposite and advancing ends of the fly-arms will strike the
upper edges of the sheets forward and lay them over flat upon the moving tapes 62.
When it is desired that the product shall be whole or full sized sheets, associated
in pairs and folded as just described, the web after being split will have its halves.
associated by laying one beneath the other before they are cut into sheets
When the delivery Apparatus is located as in Figs. 3 and 4 the halves of the
split web may be associated by the use of a turner, 69 of any convenient form as
shown in Fig. 4. or by a turner consisting of two parallel bars arranged obliquely
across the path of the part of the web to be turned or transferred laterally. In
this case one of the parts of the split web will pass around roll 14 and directly on
to carrier 15 while the other will pass around roll 91 and then around the turner 69,
by which it will be transferred laterally and then on to the carrier 15 beneath
the other part of the original web. The turner 69 will be adjustable so that
its position can be varied to secure the proper registration of the impressions
upon the associated webs. As in using a turner of the construction shown the
web in passing around it will be turned over the plates must be arranged accordingly
upon the cylinder.
When the delivery apparatus is located as in Figs 7 and 8 the halves of the
split web will be associated by adjusting the bar and plate 76, 79 to the position
shown in dotted lines in Fig 8 and then leading one half the web around bar 75
and the other half around bar 76 by which as will be readily seen both halves will
be turned at right angles to their previous path of travel and will at the same
time be placed one beneath the other. The two halves thus associated will be led
beneath Guide roll 85, the lower end passing directly on to the carrier 15 and the
upper one passing over roll 94 on to said carrier. It is to be remarked that rolls
14, 85, and 94 are all adjustable so as to regulate the distance travelled by the
webs passing over then, in order to secure the proper registration of the webs with
each other and the cutting mechanism. The associated webs after entering into
the bite of the carriers will of course be operated upon in the same manner as the
single web as already explained
When it is desired to deliver the printed product in half sheets as herein before
set forth, the carrier 15 will be set so that its groove 51 will co-act with severing
blade 40 which will also bring groove 50 into position to co-act with blade 41 as
shewn in Fig. 12 and the bar 76 will be brought to the position shown in full
lines in Fig 8. The web after passing around roll 14 will pass on to carrier 15 as
shown in Fig 4 or around the turner and roll 85 on to the carrier 15 as shown in
Fig 7. When the leading ends of the two portions arrive at the bite of the
carriers 15, 16 a lug, 95 upon the end of the carriers 16 (see Fig 10) will come into
contact with arm 31 by which said arm will be moved so as to protrude pins 21
and cause them to impale the ends of the web so that they will pass around with
the carrier 15. When the carrier has made one-half a revolution the web will be
severed by the blade 40 coacting with groove 51, and at the same time the freshly
cut ends will be impaled by the pins 39 (which will be protruded by the lug 96
upon the carrier 15 coming into contact with the arm 8s) and be carried around
upon carrier 16 (See fig 12). Soon after the blade 40 severs the web the folding
blade 36 will fold the severed sheets between rolls 37-38 at which time the arm
coming into contact with the Stationary cam 97 will be moved so as to retract the

page_text: pins and release the leading ends of the sheets. When the carrier 16 has made
half a revolution from the point where the pins 39 were protruded the blade 41
coacting with groove 50 will sever the web and the pins 21 will be again
protruded as before explained, The sheets folded by blade 36 between rolls 37. 38
will be carried onward by tapes 45 and will arrive at the bite of the tapes and
carrier 16 just in the rear of the folding blade 42 so as to underlie a considerable
part of the sheets held by pins 39 (See Fig 13). When the blade 42 arrives in
proper position it will fold the sheets upon carrier 16 between rolls 43. 44 the
pins 39 being at that time retracted by the cam 90 and said sheets and the sheets
from the carrier 15, which underlie them will together pass between rolls 43. 44
and into the curve of the arms of the revolving fly. By this arrangement the fly
acts upon two sheets at a time and it is permitted to revolve at the same speed
when delivering half as when delivering whole sheets.
When the delivery apparatus is set to operate upon half sheets the pins 20 will
remain retracted and idle there being no lug upon carrier 16 in proper position to
act upon arm 30 to protrude them
A set of horizontal tapes 98 may be arranged as shewn in Figs 7 and 8 to aid in
conducting the web around the turner in threading the machine
In Fig 17 the sheet holding pins upon the folding and carrying cylinders 15. 16
are controlled by devices of a different construction from those already described,
In this case the rock shafts by which the pins are operated are provided with cross
heads, as 117 126. 127 each of which is provided at one of its ends with a rod
as 118. 122. 128 which slides in bearings formed in ears projecting from the heads
of the carrier These rods are provided with spiral springs (not shown) which
operate in the usual manner to press the rods outward, so as to normally hold the
pins in a retracted position, The cross heads at their opposite ends are provided
with studs as 116, 124 125 which engage with and travel upon the peripheries of
fixed cams 114. 119, These cams are of such form and size and so positioned that
while the studs travel upon their peripheries as the carriers revolve they will cause
the pins to move in and out, but for a purpose to be hereinafter explained, they
will not cause the pins to protrude beyond the surface of the carriers, When,
however, loose thimbles as 115 123 are placed upon the studs the latter will be
forced outward so much that the action of the cams will carry the pins outside the
surface of the carriers at the proper points, The cams 114. 119 are provided as
shown with swinging extension plates 110, 121 which may be secured to the faces
of the cams or set in recesses formed for the purpose; These plates are secured to
the cams by pivot screws or studs so that they may operate to enlarge the cams
when desired, they being for that purpose provided at their ends opposite to their
pivots with holding screws by which they may be retained in their positions of
adjustment,. These holding screws may be common set screws working in tapped
holes, but it is preferred to use common bolts and nuts as they are adapted
to be used with slots as 112, 129 which admits of nice adjustment-Only the
heads 111, 130 of the bolts are shown it being readily understood these heads are
attached to shanks that pass through the slots and carry at their opposite ends
puts which bear against the opposite face of the cam; When the pins are operated
by these devices and it is desired that the product should he delivered in half
sheets once folded, the carriers will be set as shown in the figure so that severing
blade 40 will co-act with groove 51 and severing blade 41 with groove 50,. The
extension plate 110 will be moved outward so as to extend beyond the edge of
cam 114 the extension plate 121 will be moved inward so as to be entirely
within the edge of cam 119 and thimbles, as 115, 123 will be placed upon the
studs 116, 124,. The parts being thus arranged, the pins 21, when they arrive at
the bite of the carriers, will be protruded and impale the leading end of the web
and carry it around on the carrier 15, At the end of a half revolution the web
will be severed by the blade 40 and the freshly cut ends will be taken by pins 39
which will at the same time be protruded by the action of the extension plate 110
upon thimble and s'ud 115, 116, Shortly after this the pins 21 will be permitted

page_text: to withdraw and the sheet or sheets upon carrier 15 will be folded by a blade 36
in the manner already described,. The blade 41 will next come into action to
sever the web and the operation will be repeated, the sheets being delivered as
already set forth,. When it is desired that the product shall be whole sheets twice
folded transversly the carriers will be set so that blade 40 will co-act with
groove 49 the thimble 123 will be removed from stud 124 and placed upon
stud 125, plate 110 will be moved to the position shown in dotted lines and
plate 121 will be moved outward so as to extend beyond the edges of cam 119,.
From this change of the thimble it will readily be seen that pins 20 which were
before inoperative will be made operative and the pins 21 which were before
operative will be made inoperative, while from the change in the positions of the
extension plates the pins 20 will be kept longer in their protruded position which
is required when whole sheets are operated upon and the pins 39 be permitted to
remain retracted until they have passed the bite of the carriers and arrived in
position to take the folded sheets as they advance from between tapes 45 and
guides 46,. The operation of the delivery apparatus when thus adjusted will in
the folding of whole sheets twice transversly be the same as already setforth and
consequently needs no further specific description
When it is desired to produce an eight paged product in addition to a two paged
and a four paged signature a collecting mechanism of the following character,
which forms the third head of this invention is placed between the cutting
Cylinders and the folding Cylinders by which mechanism two or more of the
successively produced sheets are associated to form a single product.
This head of the Invention consists broadly in causing say the rear sheet or
sheets during some portion of its or their travel through the delivery mechanism
to move at a greater speed than the advance sheet, so that the sheets will be
caused to overlap each other and eventually be imposed upon one another in proper
register and embraces mechanisms by which this result is accomplished
Figures 18 and 19 Sheet VII of the accompanying drawings include so much of
a delivery apparatus as is necessary to illustrate this head of the invention, Fig 18
showing in longitudinal vertical section one embodiment thereof and Fig 19 a
modification in which the same result is obtained by different means, i.e by varying
the mode of driving the two paths of Tape
Referring now to Fig 18 it is to be understood that the web of paper after being
perfected by any ordinary form of printing mechanism is severed into sheets and
the sheets separated from each other by any common means as the well known
accelerated tapes and pulleys, so as to provide working spaces between them in
their line of travel after which they are caused to enter the bite of the Rolls 1. 2,
Leading from the rolls 1. 2 to the rolls 6. 9 are two pathways of equal length the
entrances to which are controlled by a common oscillating switch 16, The upper
of these pathways is formed by the series of tapes 3. 8 and the fixed guides 17
The first of these series of tapes passes around roll 1 over rolls 4. 5 around roll 6,
and returns over tightening roll 7, while the second passes around rolls 4 and 5.
The lower pathway is formed by the series of tapes 10 14, fixed guides 17 and 20,
and roll 11. The first of these series of tapes passes around roll 2, beneath
rolls 11 12, around roll 9, and returns under tightening roll 13 while the second
passes around rolls 15 and 12.
It is also to be understood that the various rolls just mentioned are connected
with each other and with the printing mechanisin or other source of power by
suitable gearing or otherwise, so as to receive uniform and appropriate notion, and
that the switch 16 is provided with the usual devices to cause it to oscillate at the
proper times.
These
Situate at a suitable point between the rolls 15 12 is a roll (or series of pulleys)
18, directly below which is a co-operating roll (or series of pulleys) 19.
two rolls, which are circumferentially grooved to permit the passage of the
tapes 10 14, and have corresponding portions of their peripheries depressed or cut
away, as shown are so geared or otherwise connected with some moving part of the

page_text: machine as to have a surface speed less than that of rolls 1, 2 and tapes 10, 14
As the leading end of the first sheet emerges from between the rolls. 1, 2 the
switch 16 will be in position to cause it to enter the lower pathway, in which it
will pass forward beneath roll 11 and guides 20 and enter between tapes 14, 10
by which it will be carried forward between the depressed portions of rolls 18, 19
until it arrives at the position shown. At or about this time the switch 16 will
be moved, so as to guide the second sheet into the upper pathway, and the
rolls 18 19 will have arrived at such position as to bring their full portions into
biting contact, thereby grasping the sheet passing between them and reducing its
speed to that of their surfaces. The sheet thus held by the rolls 18, 19 will
continue to be advanced slowly until its leading end arrives at the bite of the
roll 12 and tapes 10, at which time the leading end of the following sheet which has
passed forward unretarded in the upper pathway, will have overlapped the first
sheet and arrived at the bite of the roll 5 and the tapes 3. When the sheets are in
this position the depressed portions of the rolls 18 19 will again come together,
thereby releasing the first sheet and permitting it to resume its normal speed, so
that the two sheets will pass forward between guides 17 and tapes 3 10, meet each
other, and issue together from between rolls 69, to be thereafter flown folded, or
further operated upon by any appropriate delivery apparatus. The switch 16
having at the proper time been again moved, the third sheet will be sent into the
lower pathway to be in like manner retarded, and so the operation will continue to
be repeated.
It will be observed that the roll 15 is so placed that the tapes 14 10 are slightly
convergent which fact prevents them from crowding upon and wrinkling the rear
end of the sheet after it has been grasped by the rolls 18 19.
From the foregoing it will readily be seen that to effect the proper retarding of
the sheets passing along the lower pathway the speed and structure of the
rolls 18 19 must be proportioned to the length of the sheets and the working
spaces between them. Any increase in the length of the sheets or of the working
spaces makes a corresponding increase in the distance to be gained by the rear
sheet and vice versa To provide for this, the retarding of the advance sheet must
be varied. This can be accomplished in the structure shown, by decreasing the
speed of the rolls 18 19 which will increase the retarding in degree or by lessening
the extent of their depressed portions which will increase it in duration or both
and vice versa.
Although it is preferable that the retarding rolls should have portions of their
peripheries depressed, as. shown, yet such depression is not absolutely essential.
They may be made perfect rolls, so as to act upon the sheet during the whole of its
passage between them in which case, as the duration of their action will be
extended, their speed can be proportionately increased. In such case it will of
course be necessary to place the retarding rolls the full length of the sheet in the
rear of the bite of the roll 12 and tapes 10.
When the retarding-rolls are provided with depressed portions as in the present
case they may be placed at any convenient point between the rolls 12 15 as they
can be so timed in their movements as to release the sheet while it still exten.is
between them; but even in this case it is preferable that they should be placed
about the length of the sheet to the rear of the bite of roll 12 and tapes 10, in
order that they may act upon the sheet near its rear end.
The retarding rolls, instead of being constructed as shown may be perfect rolls,
and be made to act intermittently upon the sheet by being moved periodically into
and out of biting contact with each other.
The sheet in the lower pathway, instead of being simply retarded may be
completely arrested until the following sheet has arrived in a position abreast of it
in the upper pathway, and then be released. It is however preferable not to bring
the sheet to a full stop, as it will resume its normal speed much more promptly.
when released if it has at that time a slight motion. For the same reason it is also
advisable to so place and time the retarding devices that simultaneously with their,
R

page_text: release of the sheet its forward end will be caught in the bite of the roll 12 and
tapes 10.
It is evident that the leading sheet, instead of being retarded or arrested, may be
allowed to pass forward at its normal speed, and the second sheet be acted upon by
mechanism substantially like that shown, or by other suitable devices, so as to
have its speed accelerated and cause it to overtake and become associated with the
first, and that such method and mechanism would be broadly embraced in the
present arrangement.
If at any time, instead of delivering the sheets associated in pairs it should be
desired to deliver them singly it can readily be done in the mechanisin shown by
securing the switch 16 in the position shown in the drawing. All of the sheets
will then be guided into the upper pathway and issue singly from between the
rolls 69, to be acted upon in any desired manner.
If it should be desired to associate more than two sheets, it can readily be done
by increasing the number of the pathways and causing the leading sheets to be
retarded or the rear sheets to be accelerated sufficiently to bring them all abreast
at a common exit. The same result may also be accomplished by duplicating the
apparatus and causing the succeeding pairs of sheets, as they emerge from between
the rolls 69, to be guided into different pathways where one pair will be retarded
or accelerated so as to bring the two pairs together at the final exit.
Fig 19 shews a modification of the above described mechanism for associating
sheets and delivering them in pairs superposed and consists in driving the tapes
which form the two paths at different speeds.-The upper path moving at the
required fast speed of the printing mechanism and the lower path at a slow or
varying speed so as to receive the sheet at full speed until clear of the switch then
to reduce the speed and again accelerate it in time to move the sheet forward to
register with the sheet received and forwarded by the upper or quick path.
The
The upper path is formed as in the former case of two tapes 3 and 8 which as
before are driven at an equal and fast speed in any convenient manner.
switch 16 guides and supports the paper between the rolls 1. and 4 and the fixed
guide 17 between the rolls 5 and 6. The tapes 3 and 3* lead from the delivery
roll of the printing mechanism; the tape 3. over the guide rolls 1*. 2* and the
tape 3*. over the guide rolls 2* 2 thus providing a path of travel for the sheets
from the printing mechanism to the bite of the rolls 1. 2. The lower path is
formed by the tapes 10 and 14 as before the tapes 10 passing over rolls 15 under
rolls 11 and 12 and round roll 15*. and the tapes 14 round rolls 11 and 12.
guides 17 are also provided as in the former case. The tapes forming the lower
path of travel are driven at a variable speed from the shaft o which is geared to
the printing mechanism or to other convenient prime mover.
The shaft a carries
two disc wheels a'. a. which have teeth on portions of their periphery only and
these wheels gear with similar wheels b¹. 62 carried by a shaft b.
Fixed
The shaft b. is geared with the roll 11. by equal sized pinions and the rolls 11
and 15 carrying the tapes of the lower path are geared together by equal sized
pinions.
When motion is communicated from the shaft a. to the shaft b. through the toothed
portions or segments of wheels a'. and b'. the tapes 10 and 14 forming the lower
path will travel at the normal speed but when the toothed segments a*. and b³. are
in gear, the speed will be lessened until the toothed segments a¹. and b¹ come again
into gear when the tapes will again travel at full speed to deliver the sheet between
them and receive the next. In the meantime another sheet has been passing by
the upper path and the two issue together by the rolls 6. 9 as in the former case.
To ensure the proper interlocking of the segmental gearing each wheel a¹. b². is
provided with a pin or stud a³. b³, which enters into a cam shaped groove a b
inade in the face of the two wheels a².. 6². respectively as clearly indicated in the
drawing.
This modification without the driving gear is shewn as applied to printing and
folding mechanisms at the right hand side of Fig: 1 Sheet I.

open or once folded sheets and for dividing the sheets delivered from the printing
or folding machine into quires or lots containing predetermined quantities.

for effecting this object Fig: 21 is a side elevation partly in section of the same,

apparatus for placing the indicating marks upon the papers Fig: 24 is a view

elevation shewing the pile of papers as they will appear upon the carrying-tapes

marks placed in a different position.
The apparatus illustrated in the Drawings is designed and adapted to manipulate
a double-width web so as to deliver the printed product in the form of quarto or
eight-page papers having one longitudinal fold. The double-width web of paper
having been perfected by any ordinary form of printing mechanism, (the last type
and impression cylinders 47. 48 of which are shewn in Fig: 21) passes over the
roll 1. where it is split by the slitter 2. after which the two halves of the web pass
around the turning-edges 3 of a longitudinal folder, by which they are associated
in the well known manner, so as to pass between rolls 4. 5 in the form of a two-ply
web. The folder by which the two parts of the web are associated may be
of any approved form. From the rolls 4. 5 the web, now of one half its
original width passes around the turning-edges 6. of a second longitudinal folder
which is of the same construction as the first but arranged at right angles thereto
by which it is folded longitudinally, so as to pass between rolls 7. 8 in the form of
a four-ply web. It only remains now to sever the folded web into sheets of the
proper length to complete the product, and this is done by cutting mechanism
carried upon cylinders 9. 10. The cylinder 9. which is of a circumference equal to
the length of two sheets, is provided with two cutting blades 11 see. Fig: 22 which
co act with grooves 13. of the cylinder 10. which latter is of a circumference equal
to three times the length of the severed sheet. The cylinder 10 is provided with
three sets of sheet-holding pins. 16. 17. 18 placed just in the rear of the cutting-
grooves and pivotted to the ends of arms 19 which project from rock-shafts 20.
journaled upon the interior of the cylinder. The rock-sbafts 20 are also provided
with arms 21 the ends of which carry bowles, which travel upon the periphery of
the fixed cam 22. which operates in the usual manner to rock the shafts 20. and
cause the pins to protrude through openings in the cylinder. The pins 16. 17. 18
are provided with coiled springs 45. which, as shewn in Fig: 22 encircle the pins,
bear against the arms 19. and seat upon the interior of the cylinder, so as to
normally hold the pins in a retracted position. Just in advance of the cutting-
grooves 13. the cylinder 10. is provided with recesses in which lie series of fingers
12. which are fixed to shafts 14. provided with arms 15. extend inward and carry
bowles, which travel upon the periphery of a fixed cam 23 so formed as to cause
the fingers 12. to be thrown outward from the cylinder at certain points for a
purpose hereinafter to be explained The shafts 14 are provided with coiled
springs (not shewn) which operate in the usual manner to hold the fingers normally
within the surface of the cylinder.
Placed just below the cylinder 10. and at a short distance therefrom, is the small
cylinder 24 provided with four sets of grippers. 25. the shafts 26. of which are
provided with coiled springs which operate in the usual manner to hold the grippers
in the closed position, and with arms 27 which are operated upon by the fixed
cam 28 to open the grippers at the proper time. Just in advance of the grippers 25
the cylinder 24. is provided with rubber cushions 29. so placed that as the grippers
are closed their points will rest upon said cushions, and thus secure a firm hold
upon the sheet and at the same time yield sufficiently to prevent the possibility of
the sheets being torn. As the leading end of the web arrives at the bite of the
cylinders 9. 10 it will be impaled upon the pins 16. which will be protruded at

page_text: that point by the cam 22. and will be carried around upon the cylinder 10.-When
this cylinder has made one-third of a revolution one of the cutting blades 11.
coacting with groove 13. will sever the web, and the freshly-cut end will at the
same time be impaled upon the pins 17. to be carried forward in like manner.
When the cylinder 10. has advanced to such a position as to bring the rear end of
the sheet carried by the pins 16. opposite to the cylinder 24. the cam 22. will permit
the pins 16. to be retracted so as to release the head of the sheet, and the fingers 12. will
be at the same time operated by the cam 23. so as to throw the rear end of the sheet off
from the cylinder 10. and against the surface of cylinder 24. where it will
immediately be caught by one of the sets of grippers 25 the arm 27 of which will
at that point be released from the cam 28. so as to permit the grippers to close.
The sheet thus released from the cylinder 10. will have its rear end carried down-
ward by the cylinder 24. until it is brought nearly into contact with the travelling
tapes 30. when the cam 28. will operate to open the grippers 25. and release the
sheet which will then drop onto the tapes, to be conveyed away from the machine
in the usual manner. The cylinder 24. is so timed that it makes one-quarter of a
revolution while the cylinder 10. is making one-third of a revolution, so that when
the rear end of the sheet carried by the pins 17 has advanced to a position opposite
the cylinder 24. it will in like manner be thrown off from the cylinder by its set
of fingers 12. and be caught by the next succeeding set of grippers 25. to be carried
around and deposited upon the tapes in like manner, and so the operation will
continue to be repeated the tapes 30. being timed so that the papers deposited upon
them will fall only slightly in the rear of each other and assume the position in the
pile shown in Figures 25 and 26.
Although it is preferable that the cylinder 9 should be of a circumference equal
to the length of at least two sheets and the cylinder 10. of a circumference equal
to the length of at least three sheets, and that the cylinder 24 should carry at least
four sets of grippers, these proportions are not essential. The cylinder 9. may be
either larger or smaller than the size shown and carry a correspondingly increased
or diminished number of cutting-blades while the cylinder 10. may also be
increased or diminished in size and carry a proportionately increased or diminished
number of pins and fingers.-The cylinder 24. may also carry more than four sets
of grippers or may be provided with only two or three sets.
As before stated, the printed product, as delivered by this mechanism, is in the
form of a quarto or eight-page paper folded once longitudinally, from which it
results that the fold made by the turning surfaces and rolls 7. 8. is upon the
blank space between the pages of printed matter, and that such fold and blank
space will fall at the side of the papers as they fall onto the tapes 30.
For the purpose of indicating regular divisions in the papers, so that any desired
number can be taken without the necessity of counting, an apparatus is arranged
at some convenient point to print or otherwise make an indicating mark upon this
blank space upon certain of the papers, which mark can readily be seen as they
emerge from the machine or lie in the pile. It will readily be seen that this mark
may consist of a number as " 10" or "50" or of any arbitrary sign that may be
selected or it may be made by cutting or embossing the paper or by pasting or
otherwise attaching a small strip or tag -and that said mark may be made either
before or after the sheets are folded or at the same time they are printed. It is
also apparent that the apparatus for accomplishing the marking may be situate in
or upon the type cylinder or elsewhere so as to operate upon the web or sheets at
any convenient point during its or their passage through the printing or delivery
apparatus. and that a great variety of mechanisms may be used for the purpose
without departing from the present Invention.
For the purpose of illustrating the Invention there is shewn in the present case
a simple form of apparatus for making the indicating mark by printing, said
apparatus being placed so as to operate upon the centre or blank space of that
portion of the web which after it is split and associated becomes the outer ply as
it is passing over roll 1. before passing around the turning-edges of the first

page_text: longitudinal folder. This apparatus consists of a short roll 31. mounted upon the
shaft 32. of the slitter so as to rotate continuously therewith see figure. 23. This
roll is provided with an ink-receptacle 33 which is covered by a plate 34. upon
which is a projection 35. of suitable size and form to print the indicating mark
desired. This projection is provided with one or more slots or openings through
which project the wedge-shaped ribs 36. of a spring-seated plunger, 37. The
journal 38. of the shaft 32. is so constructed as to allow said shaft to oscillate
slightly while the journal 39 at its opposite end is made capable of slight vertical
movement. The outwardly extending end 40. of the shaft 32. is supported by a
rod 41. the lower end of which is bifurcated and embraces the shaft 42. of a cam
disc 43. the rod being also provided with a stud 44. which projects into the cain-
groove 50. of the disc-The groove 50. is of such form that during the greater part
of the revolution of the cam the rod 41 will be held in such position as to keep the
projection 35. of the roller 31. out of contact with the passing web: but at one
point it is so formed that the rod 41. will be lowered so as to bring the
projections 36. of the plunger 37 into contact with the web thereby forcing such
plunger inward and permitting ink to flow through the openings in the
projection 35. onto the web thus printing the desired mark, as 46, upon the blank
space and the fold line between the pages immediately after which the cam will
through rod 41. again raise roller 31 out of contact with the web.
The gearing by which the cam disc 43 is driven will be so proportioned and
timed that said disc will operate to lower the roller 31 so as to make an impression
upon every tenth, twenty-fifth, fiftieth, one hundreth or other paper, according to
the number which it is desired that the divisions in the pile shall contain: and
the gearing by which the shaft 32. is driven will be so proportioned and timed that
the printing projection 35. will always be in position to make an impression when
the roll 31. is lowered. These gears as well as the gears for driving the other
moving parts of the machine are not illustrated in the present case as their
construction and arrangement is only a matter involving ordinary mechanical skill
which is within the knowledge of all persons familiar with the art.
Instead of placing the indicating-mark upon the blank space of the web between
the printed pages so that it will fall upon the fold-line at the side of the pile it
will readily be seen that the mechanism for making said mark can be so placed
and operated as to print said mark upon the blank margin of the paper either at
the top or bottom of the page, so that instead of appearing at the side of the pile
it will appear upon the projecting ends of the papers, as seen upon the top of the
pile as shewn in Fig: 26. In some cases it may be found desirable to cause the
indicating mark to be placed upon several sheets in succession so as to make the
mark larger and more easily detected.
It is to be understood that the herein-described method of indicating the divisions
in the pile of papers is not confined in its application to a delivery apparatus which
delivers the printed product in the form of that herein shewn. The method may
be practised with equal facility in connection with mechanisms which deliver the
printed products unfolded or with those which impart more than one fold, it being
only necessary that the apparatus for making the indicating-mark should be so
placed and operated as to make said mark upon some part of the sheet where it can
be seen, so as to readily distinguish the sheet bearing it from the others.
In Newspaper printing as it is conducted at the present time it is often desirable
to have an edition or issue delivered from the printing mechanism in two different
forms. that is to say, one part in suitable form for carriers or street or counter
sale and the rest in form for mailing.
The fifth head of this Invention relates to a folding and delivering mechanism
designed to accomplish this object.
To this end it consists in a mechanism constructed and arranged to give the final
folds to the sheets and wrap and deliver them into the packing box in proper form
for mailing, which mechanism is also so arranged that a portion of it can be made
inoperative and that the other. portion will then operatе_ to deliver the sheets

page_text: with a less number of folds and in suitable form for carriers or street or counter
Bale.
It also consists in an improved folding mechanism and in certain details of
construction and combinations of parts all of which will be hereinafter fully
described, and pointed out in detail.

The printed sheets, before being delivered to the mechanism shewn in the
accompanying drawings and about to be described, are operated upon by any
approved form of folding mechanism so as to be reduced to a form or size suitable
for the carrier or for street or counter sale.
Folding mechanisims adapted to bring sheets to this size or form are well known
in the art and need no specific description here. If a single longitudinal fold is
sufficient to reduce the sheet or associated sheets to the required size then the
result can be well attained by passing the sheet or sheets over a folder of any
desired form. If in addition to the longitudinal fold, it is desired to fold the sheet
or sheets transversely, then an ordinary rotary folder or a rotary folder of the
construction about to be described may be placed so as to operate upon the sheets,
either before they pass to or after they pass from the longitudinal folder.
sheet or associated sheets, having been folded so as to be reduced to a size suitable
for the carrier or street sale, pass away from the end 1. of the longitudinal folder
(see Fig: 28) or other folding mechanism and into the bite of the rolls 2. 3
The
In fig: 29 Sheet X there are shown portions of the tapes 4. 5. 6 which convey
the sheets over the longitudinal folder. The tapes 4 and 5 are in this case shewn
as passing around the rolls 2 and 3 respectively and thence back around one or
more pulleys (not shown) to the starting-point. This arrangement of the tapes
has been found a very good one, as it tends to ensure the even and prompt delivery
of the sheets to the rolls 2. 3 but it is not essential. The tapes may pass around
the rolls 2. 3 or they may stop short of these rolls, and passing over pulleys as
shewn with respect to tape 6. return leaving the sheet to be projected between
guides and into the bite of the rolls. The rolls 2. 3 are connected by gears 7. 8
upon the upper ends of their shafts, through which by connection with any con-
venient source of power these rolls are positively and continuously driven their
surface speed being of course just equal to the feed of the sheet over the longitudinal
folder.
It has been found that by the use of a folding blade, constructed and operated as
hereinafter described, rolls of much smaller size than those heretofore used can be
made available in this position, and as it is desirable to make the apparatus as
compact and economical as possible the rolls 2. 3 are in the present case so reduced
in size that they are required to make two complete revolutions during the passage
of each sheet between them.
Upon the shaft of roll 2 just above gear 7. is mounted the small gear 9. which
meshes with an intermediate gear 10 through which the mechanism for making the
final fold and wrapping and delivering the sheet is driven, as will be hereinafter

page_text: fully explained. This gear 9. is mounted loosely upon its shaft, but is arranged to
be made fast to the face of gear 7. by means of the screw 11. or by some convenient
form of clutch mechanism.
If it is desired to deliver the papers folded and wrapped in proper form for
mailing the sheets will as they emerge from rolis 2. 3 be operated upon by
mechanisin now to be described.
The roll 3. has formed in one of its sides a series of recesses 12. cut to a
sufficient depth to allow the passage of the sections 13. of a rotating folding blade.
The portions of the roll between the recesses are left substantially intact so that
sufficient surface remains to insure the even feeding of the sheet between this roll
and its companion.
The ends of roll 3. are provided with rims or projections 14. (in Figures 27 and 30
rims are shewn in the other figures simple projections, these constructions being
considered full equivalents) in which is journaled the shaft 15. which is partially
sunk in a groove in the periphery of the roll outside of the recesses 12. and which
The shaft 15. is shown as
carry the sections 13. formning the folding-blade.
journaled so that one half of its diameter only is within the periphery of roll 3.
roll 2 being provided with a groove 89. to permit the passage of the shaft between
the rolls. It is not essential however that it should be located in this exact
position. It may lie wholly without or wholly within or be sunk slightly below
the periphery of roll 3.
As before stated the rolls 2. 3 are of such size that they are required to make
two complete rotations during the passage of each sheet between them. The
folding blade 13 is therefore required to act only at each second rotation of its
carrying roll it may however be so actuated as to be brought into operative
position at each rotation of the roll 3. in which case its alternate strokes will be
idle its edge passing to the bite of the folding rolls just in advance of the leading
end of the sheet and of course having nothing to operate upon. It is however.
most desirable that the blade should not make such idle strokes and consequently
it is shewn as driven so as to be brought into operative position only at each
second rotation of its carrying roll. This is effected by the following mechanism.-—
The shaft 18 is extended beyond the end of the roll 3. and is provided with two
sleeves 16 and 17 the ends of which meet. The sleeve 16. is loose upon the shaft
but is rigidly attached to the frame of the machine. The adjoining ends of these
sleeves are provided with coinciding slots 19. 20 the slot 19 containing the sliding
key 21. and the slot 20 the spring catch 22. see Figure 30 This spring catch is
secured to sleeve 17. so that when in its normal position it projects inwardly
through the slot 20 and takes into a recess 23 in the shaft 18 so that the sleeve 17
is locked to the shaft. The sliding key 21 when in its normal position rests
entirely within the slot 19. but it is provided upon its outer edge with a rack
which engages with the segment 24. upon the rock shaft 25 so that when the
latter is operated, which may be done by a handle placed in any convenient
position, the key will be moved, so as to project beyond the slot 19. and into the
slot 20 its projecting end, which is wedge-shaped, as shown, operating to raise the
5 spring catch 22 out of the recess 23. thus releasing the sleeve 17. from the shaft 18,
and at the same time locking sleeves 16 and 17 together. When the sleeves are
thus locked the gear 26 secured to the upper end of sleeve 17. becomes stationary
and operates to rotate the folding-blade 13. as will presently appear. This gear
engages with a gear 27 of equal size which is fixed to the short-shaft 28 having its
0 bearings in the end of roll 3. and in a plate 29 secured to the ends of posts 30.
projecting from the end of the said roll.
The end of the shaft 15 of the folding-blade extends through and beyond the
rim or projection 14. and has a bearing in the plate 29. This extension of the
shaft is provided with a gear 31. of equal size with the gears 26 and 27. which is
held loosely between collars 32. 33. which are fast upon the shaft. The collar 32:
is cut away for a portion of its length upon one side so as to form a circum-
ferential recess 34. of considerable extent. The hub of gear 31. is provided with a

page_text: projection 35 which extends into the recess 34. so that the gear and shaft 15. will
rotate together. The recess 34. is, however, of such size with relation to the pro-
jection 35. that for a purpose to be presently explained, considerable play or lost
motion is allowed. The shaft 15. and gear 31. may be connected by a spiral
spring 99 (see Fig: 27) the tendency of which is to hold the edge 98 of pro-
jection 35 against edge 97 of collar 32 and to return the parts to that position
when they have been forced apart The spring 99 is not however essential as the
devices will be operated when it is omitted as in Fig: 30. Sheet XI. In addition
to the gear 27. the shaft 28. is also provided with a gear 36. of one-half the other's
size which engages with and drives gear 31.
It will thus be readily seen that when the sleeves 16 and 17. are locked
together by the key 21 the devices just described will operate during two complete
rotations of the roll 3 to revolve the blade 13 once and in a direction opposite to
that of the rotations of the roll.
As before stated, the rolls 2. 3 are of such size that they are required to make
two complete rotations during the passage of each sheet between them and the
folding blade 13. is so driven as to be brought into operative position at every
second rotation of.its carrying roll 3. The blade, rotating as it does in a direction
opposite to that of roll 3. is so timed that as the fold-line of the sheet arrives at
the point of contact between rolls 2. and 3. its edge passes outside the periphery of
roll 3. and presses the sheet upon the fold-line against the surface of roll 2. as
shewn in Fig 31. During this part of its rotation upon its own axis the edge of
the blade will be carried farther and farther beyond the periphery of the roll 3. so
that it will continue to press the sheet against roll 2. and as the blade is carried
bodily onward by roll 3. in its rotation the edge of the blade will be permitted
to travel onward with the sheet as it moves with roll 2. This outward and
onward movement will be continued until just before the parts arrive at the
⚫ positions shown in Fig: 32 at which point the blade will force the fold-line of the
sheet into the bite of rolls 2 and 37 immediately after which roll 3 will in its
onward rotation, withdraw the blade and carry it rapidly away from roll 2 as
shewn in Fig 32.
"
It will be observed that the blade 13. is curved in the direction of its width,
which is an important feature of the construction no other form being capable of
operating in the manner described. This is quite evident from the fact that its
edge must follow and bear against the surface of roll 2 at the same time that its
axis (the shaft 15) comes in contact or nearly in contact with the same roll.
Although the blade 13 makes just one complete rotation on its axis while the
roll 3. is making two, its speed, as will be noted, is quite different in different
parts of its rotation at one point being accelerated, at another retarded, and at
another entirely checked. This variation of speed is permitted by the play or lost
motion which the gear 31 has upon the shaft 15 as heretofore explained and is
caused by the cam 38 on the end of roll 2. (shown in Fig: 27 and in dotted lines
in Figures 31. 34 35 and 36) and by the fixed cam 39 (best shewn in Figures 27.29
and 31).
During the first one-fourth or a trifle more of a rotation of the roll 3 from the
position shewn in Fig: 5 the speed of the blade 13. around its axis must be con-
siderably accelerated in order to keep its folding edge upon the surface of roll 2.
This acceleration is effected by the side 40 of cam 38. upon which the bowle 41 of
the arm 42. carried by the shaft 15. of the folding-blade strikes just after the rolls
pass the position shewn in Fig: 31. The rolls 2 and 3. being rotated at the saine
speed, it follows that the shaft 15. of the folding-blade and the point of cam
surface 40 at the periphery of roll 2. move with the same velocity, but the bowle 41,
being at this time considerably outside the periphery of roll 3. is moving with a
velocity much greater than that of the surfaces of the rolls, and consequently of
the cam surface 40.-As soon, however as the bowle enters within the periphery 5
of roll 2, and strikes upon cam 40. it will be held back and permitted to advance
only at a speed equal to that of the cam, which speed will constantly decrease as

page_text: the bowle passes inward onto the slower-moving portions of the cam.
This holding
back of the arm 42. draws the blade 13. outward from the roll 3. and advances it
in its revolution around its axis 15. at a speed much greater than that with which
it would be driven by its train of gearing.-The action of cam 40. upon arm 42.
will also press and hold the blade 13. tightly against the surface of roll 2. until the
fold is made, at which time the bowle 41 will pass onto the side 43. of cam 38, and
as this cam-surface will then be moving in a direction contrary to that of the
bowle in its revolution around the shaft 15. said shaft and blade will be somewhat
retarded. This will continue until the parts reach the position shewn in Fig: 32
when a little less than one half of a rotation will have been accomplished.-The
bowl 41. will then pass outside the periphery of roll 2. and the blade will resume
its normal movements. The positions which the different parts will occupy when
the spring 99 is used, when three-fourths, one, and one and one-fourth, rotations
have been accomplished are shewn in Figures 33. 34. and 35 respectively.
Owing to the play or lost motion permitted between shaft 15. and gear 31. the
blade during the last part of the second rotation will be thrown forward by the
centrifugal force caused by the rapid rotation of roll 3. and the bowle 41. will pass
outside the periphery of the roll to the position shewn in Fig: 10 where it will be
arrested by the cam 39. and from then until the second rotation is complete and
the bowle again passes onto cam 38. the blade 13. will have little or no motion
around the shaft 15.
From the foregoing it will be seen that the blade 13. when performing its work,
is operated and controlled almost entirely by the cains the function of the gears
being mainly to move it during the idle part of its rotation and to bring it into
proper position to be operated upon by the cams when required.
The roll 37 has secured to its end the gear 44 which engages with the gear 7.
upon the roll 2. so that the two run with the same surface speed.-The sheet having
been folded into the bite of these rolls by the blade 13. as already described, passes
between them, and is projected between guides 45 supported by rods 53. until it is
caught in the bite of rolls 46. and 47. These rolls are provided upon their ends
with engaging gears 48. 49 the latter also engaging with gears 59 and 60, by
which they and folding and delivering rolls 56. and 61 are driven from gear 9.
through intermediate gear 10. The rolls 46. 47 are of the same size as rolls 2, 3
and owing to the reduced size of the sheets upon which they operate are required
to make but one rotation during the passage of each sheet between them.--This
permits them to be driven at one-half the speed of the former. Hence the reduced
size of gear 9.
As the sheets pass between the rolls 40. 47 they are associated with wrappers in
the following manner: Upon the horizontal shaft 50. which is mounted in suitable
bearings is placed a roll of wrapping material, the end of which, being conducted
over the angularly-arranged turner 51, is introduced between the rolls 46. 47. and
impaled upon the pins 52, carried by the former. The wrapper will thus be drawn
forward and associated with the incoming sheet, the pins 52 serving to hold the
leading end of the wrapper and with it the sheet onto the roll 46.
It is to be remarked that the sheets before passing between rolls 2, 37 will be so
accelerated that they will be separated some distance from each other, and also that
the rolls 46. 47 are of such size that the length of the transversely-folded sheets
passing to them is equal to only about three-fourths the circumference of these
rolls. These rolls are therefore so timed in their movements that the sheets will
enter their bit a short distance behind the pins 52 and the leading end of the
wrapper.
In order to afford room for the accumulated thickness of paper contained in the
folded sheets, the rolls 46. 47 do not run in close contact; but to give the rolls a
firm hold upon the leading end of the wrapper and to ensure its being impaled
upon the pins 52. the roll 47 is upon that portion of its surface between the leading
end of the wrapper and the point where the incoming sheet enters, provided with a

page_text: projection 54. formed of rubber or any suitable material, of such thickness as to
press tightly against roll 46.
The roll 46 except in particulars specified is of the same construction as roll 3
and carries a folding-blade 55 of the same construction and having the same
operation and auxiliaries as the blade carried by that roll, except that blade 55 is
made to revolve about its axis once for each rotation of its carrying roll.—This
difference in speed is effected by making the gear corresponding to 36 of the same
size as that corresponding to 31. or by omitting 36. and making the gear corre-
sponding to 27. engage directly with that corresponding to 31.
The wrapper and sheet passing between the rolls 46. 47 will be carried by the
pins as already stated, upon the surface of roll 46 until the fold-line reaches a point
directly between the axes of the rolls, at which time the blade 55. will pass outside
the periphery of roll 46 and striking the sheet upon the fold-line press it firmly
against roll 47. and tearing the end of the wrapper from the pins fold both wrapper
and sheet between rolls 47 and 56 in a manner already described. As the sheet
and wrapper thus folded pass onward between the rolls 47. 56. the rolls 46. 47
complete a rotation when a severing-blade, 57, set in roll 46 cutting into a
groove 58 in roll 47, severs the wrapper from the web, leaving a projecting end for
a sealing flap, as shown, and at the same time the pins 52. impale the fresh end of
the web and carry it forward to form a wrapper for the next succeeding sheet.
In the operations described the sheet, which was received in a form suitable for
the carrier or street sale, has received two parallel transverse folds, which has
reduced it to a form suitable for the mail, and has had a wrapper folded around
it. It now remains to fold down the projecting ends of the wrapper, seal it, and
deliver the product from the machine.
As the sheet and wrapper pass between rolls 47. 56 a pasting device carried by
the latter places a transverse line of paste upon the wrapper at a suitable point to
secure the longer of the projecting ends. This pasting device consists of a
cylindrical tank 62. having a narrow opening along one side, and in which is
journaled a paste-roll 63. so positioned that it will close the opening in the side of
the tank. This roll is made with a series of longitudinal grooves, in which the
paste will be carried through the opening in the tank.-This tank is inserted in a
recess formed in the side of the roll, so that the projecting surface of the paste-
roll 63. will be flush with or project slightly beyond the surface of roll 56. The
roll 63. coming in contact with the wrapper as it and the sheet pass between
rolls 47. 56 will by the pressure of the package be caused to turn slightly in its
bearings, thus bringing out a groove filled with paste, which will be applied in a
line to the wrapper, and as each succeeding sheet and wrapper pass a fresh groove
will be brought out with the same result. It will of course be understood that
when a paste-fountain of this kind is carried in a roll, as in the present case,
provision must be made for keeping it constantly filled. This can be done in a
variety of ways as will readily be seen. The roll 56. is of the same construction
except as to the pasting device, as roll 3 and carries a folding-blade, 64. of the same
construction and operation, and having the same auxiliaries as blade 55.
roll 56. is however, so timed that the blade 64. does not strike the sheet, but strikes
just in its rear and upon the projecting ends of the wrapper. The result is that
the sheet is not folded between rolls 47. 61 but that the projecting ends of the
wrapper are laid over upou its body, and as the wrapped sheet passes between the
rolls the longer of the projecting ends is pressed upon the line of paste and secured.
The sheets may be so fed to rolls 46. 47 that the second cross-fold will be made
a little in advance of their centres, leaving the ends uneven, in which case the
longer end may be struck by blade 64 and folded over with the projecting end; of
the wrapper, which will tend to make the wrapper more secure.
The
It may be remarked that roll 47 is provided with two cams corresponding to
cam 38; one 65 to operate blade 64, and another, 66 to operate blade 55. As the
wrapped sheet enters the bite of rolls 47. 61 its leading end is caught by the

page_text: grippers 67 which are constructed and operated in the usual manner and carried
around until in a position opposite the end of the packing box 68 when it is
released and pushed into the box by the enlargement 69, on the roll 61.
The operations of the folding blade 64 and pasting device are well shown in
Figures 38 to 41 inclusive, in which Fig: 38 shews the position of the parts at the
time the line of paste is being applied to the wrapper, Fig: 39 at the time the
wrapper is being severed from the web and the blade is just pressing the projecting
ends of the wrapper against roll 47., Fig: 40 at the time the blade is folding the
projecting ends of the wrapper into the bite of the rolls 47. 61, and Fig: 41 just
before the fold is made.
If it should be desired to fold the sheet more than once transversely before
placing the wrapper around it, the roll 37 may be provided with a folding-blade of
the same construction as those in rolls 3, 46 and 56 which will operate to fold the
sheet between the rolls 2, and a companion, which can be provided, after which the
sheet will be conducted to rolls 46 47 to receive the final fold and the wrapper.
When it is desired to deliver the sheets unwrapped and in a form suitable for
the carrier the gear 9 is rendered idle by the withdrawal of the screw 11 and the
rock shaft 25 is operated to withdraw the key 21 from slot 20 which disconnects
the sleeves 16, 17 and renders the folding blade 13 inoperative, and allows the
catch 22 to pass into the recess 23 locking the blade inside its roll in the position
shown in Fig: 30.-The sheets will then pass outward between guides 75. 76 and
be taken by any appropriate form of delivery mechanism.
Although the machine here shown is arranged to operate upon the sheet while
in a vertical position this arrangement is not essential. It may be readily so
positioned as to receive, fold and deliver horizontally.
In Fig: 44 a modified construction is shewn in which the folding blade, instead
of being mounted upon a rotating carrier and itself having a rotating motion, is
mounted upon a reciprocating carrier and given an oscillating motion. The curved
blade 13 is pivotted in any convenient manner to the end of the carrier 100 which
carrier is reciprocated by any suitable means.-Rigidly attached to the back of the
blade is the arm 101 provided at its outer end with the bowl 102 which travels in
the cam groove 103.-As the blade is advanced from the retracted position shown
by the dotted lines the cam 103 acting upon the bowl 102 will depress the folding
edge of the blade and cause it to press the paper upon the fold line against the
surface of roll 2, and as the blade and roll advance together the cam will cause the
edge of the blade to follow the curvature of the roll, pressing the fold line of
the sheet snugly against it until the bite of the folding roll is reached and the fold
is made as is shown in the figure-The motion of the carrier 100 being reversed at
this point the blade will be withdrawn and returned to repeat the operation;
The sixth head of this Invention relates to a modification on the fourth head of
the Invention viz: for piling sheets one upon another and consists primarily of a
rotating sheet carrier and cooperating devices for arresting the forward movement
of the leading end of the sheet, and for distending the sheet and retaining its rear
end upon the carrier until it is entirely reversed and stripped therefrom.
In Sheets XIV and XV of the drawings Fig: 45 is a rear end elevation of a
mechanism for carrying out this head of the Invention.-Figures 46 and 47 are
vertical sections of the same upon the lines x x and y. y. respectively. Figures 48
and 49 illustrate by vertical section and plan view a modified sheet distending and
retaining apparatus. Figures 50, 51 and 52 Sheet XV are sectional views illustrating
further modifications in the same
The sheet carrier consists of a drum or cylinder 1 secured to a shaft 2 mounted
in an appropriate frame and driven from any convenient part of the printing
mechanism. This drum which is of a circumference equal to twice the length of
the sheet to be produced is provided with two sets of sheet-holding pins 3 located
upon its opposite sides and mounted upon fixed shafts 5 so as to always remain
protruded. Just in the rear of the pins 3 and lying in the same longitudinal
recesses through which the pins protrude, are sets of stripping fingers 7 which are

page_text: :
:
mounted upon rock shafts 9 located in the rear of the pins and having their free
ends extended sufficiently forward to lie between or straddle the pins as shewn in
Fig 49. The rock shafts 9 are provided with rock arms 11 the inner ends of
which are controlled by a fixed cam 13 which is so shaped as to throw the fingers
outward to strip the sheets from the pins at the proper time. The shafts 9 are
provided with springs of the ordinary construction which draw the fingers in ward
and hold the arms 11 constantly against the cam. Just in advance of the pins 3 the
carrier is provided with cutting grooves 14 which cooperate with a blade 15 carried
by a cylinder 16 of one-half the size of cylinder 1 and driven in unison therewith,
so that the blade 15 acts with both grooves 14 and severs the web at each one-half
revolution of the carrier.
In addition to the devices already specified the carrier 1 is provided with a
sheet distending and retaining mechanism consisting of the bars 17 which extend
lengthwise of and rest upon its surface. These bars are supported in four-armed
frames 21, 22 which are mounted loosely upon the shaft 2 of the carrier and a
sleeve 23 to be hereinafter referred to, and are so driven that the bars move
positively with the carrier but at only one-half its speed. This movement is
imparted to the frames and bars by means of gears 24, 25 which are fixed to the
inner sides of the frames and engage with gears 26, 27 fast upon a shaft 28
journaled in the heads of the carrier, which shaft receives a planetary motion from
its gear 29 through engagement with the gear 30 fixed upon the sleeve 23 which
surrounds the shaft 2 and is secured to the frame of the machine as shown in Fig: 45.
It is apparent that if the gears 24, 25, 30 were of the same size and the gears 26,
27, 29 also equal to each other, the gears 26, 27 would simply travel around the
gears 24, 25, and the latter and the frames 21, 22 and bars 17 would remain
stationary; but as the gears 26, 27 are only one-half the size of the gears 24, 25 it
follows that the former in making a complete revolution with the carrier will only
pass over one-half the periphery of the latter, and that the latter together with the
frames 21, 22 will during such time be carried forward with the carrier one half a
revolution from which it results as before stated that the bars 17 revolve with the
carrier but at only one-half its speed. The bars 17 are mounted to turn freely in
their bearings so as to roll instead of slide over the surface of the carrier, and said
bearings are made movable as shown in Fig: 46 and are provided with springs
(not shown) which operate to constantly draw the bars inward and hold thein
snugly to the surface of the carrier-In order to avoid contact with the sheet-
holding pins which as before stated are constantly protruded, the bars 17 are
provided at proper points with circumferential grooves 31 of sufficient depth to
allow the pins to pass unobstructed. Just in advance of the cutting grooves and
blade the carrier 1 and cylinder 16 are provided with longitudinal depressions 32,
33, 34 into which the bars 17 are drawn so as to permit them to pass the bite of
the carrier and cylinder.
:
Situated below and in close proximity to the carrier is the apparatus for grasping
and arresting the forward movement of the leading ends of the sheets to strip them
from the carrier. This apparatus consists of a skeleton cylinder 35 provided with
four sets of grippers 36 which are mounted in the usual manner upon rock shafts
provided with springs by which the grippers are closed and with arins as 37 which
are acted upon by a fixed cam or cams 38 to open the grippers at the proper time.
The parts being constructed as just set forth and provided with suitable gears so
as to have their movements properly timed with relation to each other the
operation will be as follows: The web after being perfected and if desired reduced
in width by longitudinal folding or by being split and having its sections
associated by web turners or otherwise will enter between the carrier 1 and the
cylinder 16 where its leading end will be impaled by the pins 3 so as to be held
upon the carrier. The gearing by which the frames 21, 22 are driven will be so
timed, that when the leading end of the web is taken by the pins one of the bars 17
will have just passed the bite of the carrier and cylinder 16 and as the carrier
travels at twice the speed.of the bars 17 the leading end of the web will at once be

page_text: carried forward past the bar, the spring controlled bearings and grooves 31 of the
bar permitting it to rise out of the depression in the carrier and the pins to pass
forward unobstructed. When the pins carrying the leading end of the web arrive
at a point opposite to the cylinder 35 the cam 13 will through arm 11 operate the
fingers 7 to strip the end of the web froin the pins and throw it outward against
said cylinder where it will be caught by one of the sets of grippers 36 which will at
that time be in position to close upon it.-As the carrier and the cylinder 35
continue their revolutions from this point the leading end of the web will be
stripped from the carrier and carried slowly downward and backward while the
bar 17 moving forward at one half the speed of the carrier will remain continually
in or near the bight 41 of the web keeping it distended and preventing it from
falling from the carrier faster than is necessary.-When the carrier has made one
half a revolution from the point of starting the blade 15 cooperating with
groove 14 will sever the web and the second set of pins 3 will impale the freshly
cut end and carry it forward to be in like manner stripped from the pins and
taken by the second set of grippers 36 which will then have arrived in position to
close upon it the second bar 17 being in proper position to move forward in its
bight to keep it properly distended and so the operation will be repeated at each
one-half revolution of the carrier.-When the carrier has made a complete
revolution the rear end of the first sheet will have arrived at the position shown in
Fig 47 and will be released from between the carrier and the bar 17 having been
completely reversed and stripped from the carrier.-At or about the same time that
its rear end is released from the carrier the grippers 36 will be operated to release
its leading end when it will fall flat upon the piling table or upon travelling tapes
or an apron to be conveyed away from the machine
:
It will be observed that the cam 13 is so shaped that the fingers 7 after
throwing the leading end of the web into the bite of the grippers 36 will at once
be withdrawn a short distance and will then remain projected beyond the points of
the pins until the rear end of the sheet is released thereby preventing the
possibility of the body of the sheet coming into contact with and being torn by
the pins-
Although it is believed that the best results will be obtained by making the
parts of substantially the proportions shown yet it is evident that they may be
varied to a considerable extent.-The carrier 1 may be of a circumference equal to
the length of three or more sheets and have its auxiliaries proportionately increased
in number and the number of sets of grippers upon the cylinder 36 may be increased
or diminished. The severing of the web into sheets may also be accomplished by
a cutting mechanisın entirely independent of the carrier.
When the cutting mechanisin is independent of the carrier the sheets may be
separated by short spaces before coming to the carrier in which case the fingers 7
may be omitted and the grippers 36 be made to take the ends of the sheets directly
from the carrier:―
It is also evident that this apparatus although especially adapted to operate
upon sheets which have not been reduced in length by transverse folding is
capable of delivering sheets which have been reduced to any desired dimensions.
In the Invention as illustrated in Figures 48 and 49 the sheet distending and
retaining bars and their frames are omitted the sheet being kept properly distended
while being stripped from the carrier by jets of air which enter its advancing bight.
The apparatus for this purpose consists of a series of nozzles 39 connected through
a pipe 40 with a fan or other blower and projecting inward and forward from the
side of the carrier so that as soon as the leading end of the web is caught by the
grippers 36 it will be subjected to an air blast which will keep it properly
distended and advance its bight 41. The nozzles 39 will be arranged in a
progressive series as shewn so that the air pressure will not be diminished as the
bight advances. It will usually be advantageous to arrange a series of these
nozzles upon each side of the carrier although but one series is shown in the
present case.

page_text: In Fig: 50 Sheet XV the air nozzle 39 instead of being located at the side or
sides of the carrier are placed just in the rear of the skeleton cylinder 35 so that
the jets of air enter the bight of the sheet directly from the rear instead of
laterally. Fig: 51 shows a moving air blast apparatus for the same purpose.-In
this case the bars 17 instead of rolling freely upon the surface of the carrier are
made rigid with the arms of the frames 21, 22 and move out of contact with the
carrier. These bars are hollow and are provided upon their front sides with
openings for the emission of jets of air said air being forced into said hollow bars
through openings in the hub 42 and arms of the frame 22.-By this arrangement
the air blast apparatus advances with the bight of the paper and the jets of air are
delivered in close proximity thereto so that a much smaller amount of air suffices
than when the jets are delivered at a greater distance from the paper.
By the arrangement shown in Fig: 52 the paper is held to the carrier and kept
distended by suction instead of by pressure from the exterior. For this purpose
the shell of the carrier is provided with narrow air chambers 43 which open
outwards through a large number of small perforations 44 and communicate
inwardly through the pipes 45 and an axial opening in the shaft 2 with an
exhaust apparatus. By the suction thus produced the sheet will be held to the
carrier until rolled backward and stripped off by the action of the grippers 36.
The seventh head of this Invention is designed to effect the orderly and safe
delivery of the printed sheets after they have received one or two folds by a
mechanism compact simple and inexpensive and withal capacitated to receive and
dispose of the sheets with as great rapidity as it is possible for them to be
produced.
This head of the Invention consists of an improved method of effecting the
delivery of the printed sheets and also of certain means by which this method is
carried into operation, said means consisting broadly of a conveying mechanism by
which as the sheets are led away from the delivery rolls of the folding mechanism
they are caused to overlap each other which overlapping is made to increase as the
sheets advance until they are brought to rest one above another upon the receiving
table.
It also consists in certain details of construction and combination of parts all of
which will be fully hereinafter explained.
In Sheet XVII of the Drawings Fig: 53 is a longitudinal vertical section of a
mechanism embodying this invention in one of its forms, the gearing and frame-
work being removed for the sake of clearness of illustration.-Fig: 54 Sheet XVI
is a side elevation showing the devices by which the parts are driven Fig: 55 is
a plan view of that portion of the machine shewn in Fig: 54.-Figures 56 and 57
Sheet XVII are diagrammatic longitudinal vertical sections of Figures 54 and 55
showing the parts in different positions.-Fig: 58 is a diagrammatic section showing
a modification to be hereinafter referred to.
The web of paper having been operated upon by the ordinary perfecting printing
devices is severed into short lengths or sheets which are carried by the tapes 1, 43
over the folder 2.-The speed of said tapes may be so accelerated that the sheets
are separated from each other a sufficient distance (about one fourth their length
in the machine shown) to allow the grippers carried by the folding cylinder 6 to
operate freely. The tape 1 passes between rolls 3, 4 around cylinder 6 and back
to its starting point while the tape 43 passes between rolls 3, 4 along cylinder 6
and thence around roll 8 and a roll or pulley (not shown) to its starting point.-
These tapes conduct the sheets over a folder 2 of any approved form by which they
are folded longitudinally and delivered between the rolls 3, 4 to the grippers 5 of
the sheet carrying cylinder 6.
The grippers 5 are of the usual construction and are operated by any of the well
known devices so as to seize and release the sheet at the proper times.-The
cylinder 6 is also provided with the rotating folding blade which may be either
double or single and which is also of the common construction and is so operated
by the usual devices that its edge or one of its edges is brought into operative

page_text: position at each revolution of the cylinder and the sheets taken by the grippers
folded by it between the rolls 8, 9 from which it is projected between the upper
and lower guides 10, 11 supported upon rods 13, 14 extending transversely of the
machine.
The carrying cylinder 6 which is driven by connection with any suitable moving
part of the printing mechanism has secured to its shaft the gear 12 which engages
with gear 15 upon the shaft of roll 8 which latter engages with gear 16 upon the
shaft of roll 9 these three gears being of such relative sizes that the three carriers
are driven at the same surface speed.
As has been already stated the sheets as they pass from the folder 2 are shown
as separated by spaces equal to about one fourth their length and the transverse
fold between the rolls 8, 9. reduces them to one half their original length from
which it follows that as the folded sheets emerge from the rolls 8, 9 they will if
their speed is not checked be separated by spaces equal to one and one-half times
their folded length.
Located at a distance a trifle less than the length of the transversely folded
sheet from the rolls 8, 9 are the feeding rolls 17, 18.-The sheet will be advanced
by the rolls 8, 9 into the bite of the rolls 17, 18 and will be fed onward by the
latter after being freed from the former The shafts of rolls 17, 18 are provided
with engaging gears 19, 20 and are driven through the intermediates 21, 22, 23
from the pinion 24 upon the end of the shaft of roll 9 which pinion is of such size
that the surface speed of rolls 17, 18 will be but one third that of rolls 8, 9
The result of this is that the sheet is advanced by the rolls 8. 9 with a speed
equal to that of their surfaces until it reaches and enters the bite of rolls 17, 18 at
which time it ceases to be acted upon by the former rolls and begins to be
advanced by the latter but at only one third its previous speed.-From this it will
be seen that if the second sheet enters and is folded between rolls 8, 9 as soon as
the first passes from them it will be advanced its entire length and reach
rolls 17, 18 while two thirds of the first sheet still projects to the rear of said
rolls and the sheets will overlap two thirds of their lengths, but as has already
been explained the fold line (which after folding becomes its leading end) of the
second sheet is separated from the rear end of the first sheet while they are upon
the cylinder 6 and folder 2 by a space equal to one and one-half times the length
of the sheet after folding so that after the first sheet leaves rolls 8, 9 the second
must travel this distance before entering between these rolls.-This allows about
one half the length of the first sheet to pass between rolls 17, 18 before the second
sheet enters between rolls 8, 9.-The whole of the second sheet must then pass
between rolls 8. 9 before reaching rolls 17, 18 and while it is doing this the first
sheet will advance one third its length between rolls 17, 18 so that when the second
sheet enters between rolls 17, 18 and both begin to travel together they will
overlap only one sixth their lengths.
To insure that the leading end of the second sheet shall pass above the rear end
of the first in overlapping and to prevent the fouling of the sheets, the rotating
guide and knocker 25 is provided. This device consists of a series of fingers
secured to the shaft 26 of gear 22 and so arranged as to pass in their rotations
through the spaces between the guides 10, 11. The gear 22 is made of such size
that the knocker shaft makes one revolution to the passage of each sheet.-
Therefore this shaft is so geared as to revolve in unison with the shaft of
cylinder 6 and the shaft 26 is so positioned and timed in its rotations and the
rotating guides or knocker fingers are of such a length that as they pass upward
between the guides 10, 11 they will be in the rear of the sheet and that as they pass
downward upon the opposite side of shaft 26 their sides 27 will overlap and strike
upon and depress the rear end of the sheet.-While the rear of the sheet is thus
depressed the leading end of the following sheet passes along the backs of the
fingers of the knocker and is guided above the depressed end of the first sheet so
that the ends overlap.
The positions of the parts at the time the overlapping takes place is shown in

page_text: Fig: 56 in which the upper guide 10 is shewn as being slightly curved. Fig: 57
showing the position of the parts when the overlapped ends have advanced to the
bite of the rolls 17, 18 and the rear sheet is about to be released from rolls 8, 9.
In order to permit the depression of the rear end of the sheet the under guides 11
terminate a sliort distance in advance of the shaft 26 of the knocker leaving the
sheet unsupported for a short distance.-The sheet may be supported for a short
distance in the rear of rolls 17, 18 by short guides 28 supported upon the transverse
rod 29 as in Figures 56 and 57 or the under guides 30, to be hereinafter described,
may extend to the rear of roll 18 and perform this function.-The sheets having
been overlapped as described are by the rolls 17, 18 fed forward between guides
30, 31 supported upon transverse rods 32, 33.
Located at a distance a trifle less than the length of a sheet in advance of the
rolls 17, 18 are the rolls 34, 35 into the bite of which the sheets are delivered just
as they pass from rolls 17, 18.-The rolls 34, 35 are driven by belts 36, 37 from
pulleys 38, 39 upon the shafts of rolls 17, 18 said pulleys being of such a size that
the rolls 34, 35 have only one third the surface speed of the rolls 17, 18.-The result
of this is that after the first sheet passes froin between rolls 17, 18 its speed is
again reduced two thirds and the second sheet which continues to be acted upon by
rolls 17, 18 rapidly advances along the top of the first so that when the second
arrives at the bite of the rolls 34, 35 the two will overlap about thirteen-
eighteenths. As the first sheet emerges from rolls 34, 35 it is projected onto the
receiving table 40 and is brought to rest against the stop 41 the second and
succeeding sheets being in like manner projected along the upper surface of the
preceding sheets and against the stop.
•
The piling table 40 is supported by a spring 50 arranged as shewn in Fig: 53 so
that as the pile of papers increases, its weight will gradually press the table down-
ward so that the top of the pile will always be about level with the bite of the
rolls 34, 35.
Instead of being supported by a spring so as to be lowered by the weight of the
pile of papers the table may be lowered by an automatically operated pawl and
ratchet mechanism. Such mechanisms being in common use for lowering and
raising piling and feeding tables are well known and need no specific description.―
The construction shown in Fig: 58 is in all respects similar to that shown in
Fig 53 except that the knocker 25 is placed above instead of below the
guides 10, 11.
As heretofore stated the present mechanism is designed and adapted to deliver
the printed sheets in a form suitable for carriers or for street or counter sale. When
however it is desirable to have a machine capacitated to deliver the product of the
printing mechanism in either this form or in form suitable for mailing a switch 42
may be placed just in advance of rolls S, 9 which can be operated to divert the
sheets from between guides 10, 11 and direct them into the bite of tapes 43, 44
passing around rolls 8 and 45 respectively by which they will be conducted to any
other approved form of folding or folding and wrapping mechanism.-When the
sheets are directed between tapes 43, 44 the pinion 24 should be removed or
disconnected from its shaft so that the mechanism driven by it will be idle.
It is to be remarked that it is not essential that the rolls 34, 35 should be driven
by the belts 36, 37 as shown. They may be driven by a train of gearing connecting
them with gear 19 or 20.-It will also in most cases be found desirable to so arrange
the roll 34 that it will be pressed against roll 35 by springs or other analogons
devices so that it will be slightly yielding to accommodate itself to the varying
thickness of the overlapped papers passing beneath it.
The rolls 8. 9, 17. 18, and 34,-35 may consist of series of pulleys as shown or
they may be substantially continuous rolls.
Instead of the grippers as shown the cylinder 6 may be provided with pins for
holding the leading end of the sheet and the cylinder may be arranged to act as a
gathering cylinder so that two or more sheets may be associated and then folded
between rolls 8-9 in which case the folding blade will be caused to come into

page_text: operative position only upon each second or third revolution according to the
number of sheets gathered or associated. When pins are used instead of grippers
this cylinder may also be provided with a severing blade in which case the web
will not be cut into sheets before passing onto the folder 2 but will be severed
just in advance of the pins:-If in any case the operation is so modified that the
relative space between the sheets as they enter the bite of rolls 8-9 is changed
the speed of rolls 17, 18 must be correspondingly changed so as to bring the rear
ends of the sheets in proper relation to the knocker and to the following sheet.
Instead of the rotating guide and knocker as 25 arranged as shown to depress
the rear of the leading sheet it may be arranged as a vibrating guide and knocker
and operated so as to move upward and raise the leading end of the rear
sheet and thus cause it to be advanced above and overlap the rear end of the first
sheet the upward vibration of the guide being so timed as not to disturb the rear
end of the preceding sheet.
The belts 36, 37 may serve as guides in which case the guides 30, 31 may be
dispensed with.
The stop 41 may be provided with one or more slotted holes through which set
screws as 80 may pass for the purpose of an adjustable attachment to the frame 81
so that as the table 40 descends with its accumulation of papers the lowermost
ones may be drawn out from under the lower edge of said stop without interfering
with the continuity of the accumulating sheets above.-Tho. printed web of paper
as it issues from the printing mechanism may pass directly to cutting and folding
cylinders and receive the first fold transversely between the rolls 8, 9 or it may
receive two parallel transverse folds by suitable mechanism before entering the
rolls as 8, 9 in which case the position of the shafts of the rotating guide or knocker
fingers with relation to the shafts of rolls 8, 9 and 17, 18 should be adjusted and
timed to correspond to the conditions relative to the speed and size of the sheet as
has been herein set forth
It is also evident that the shaft supporting the rotary knocker tingers may be
provided with two or more series of knocker fingers and said shaft have an
intermittently rotative motion which shall cause a set of knocker fingers to act
upon the rear end of the preceding sheet and serve as a guide to direct the forward
end of the following sheet so that it shall overlap the preceding sheet substantially
as herein described without departing from my Invention.
