ALFRED VINCENT NEWTON, of the Office for l'atents, 66, Chancery Lane, in the
County of Middlesex, Mechanical Draughtsman. "IMPROVED DELIVERY APPARATUS
FOR WEB PERFECTING PRINTING PRESSES."
This Invention relates,-
Firstly. To a delivery apparatus to be attached to a web perfecting printing
press, in which the web of printed paper is severed into sheets, which delivery
apparatus runs slightly faster than the press in which the web is printed, the object
being to keep the paper free from wrinkles, and also to keep the proper tension
despite the slight variations of the speed of the paper's passage through the press,
due to the varying thickness of the plates or the condition of the paper.
Secondly. To the cutting of the web into sheets. This is effected at two operations
by the use of two cylinders and a revolving frame carrying a knife, ono of the
cylinders also being provided with a knife, and the remaining or female cylinder
containing the opening, into which first the revolving knife and then the knife
carried by the cylinder enters to cut the paper, the opening in the female cylinder.
therefore being entered alternately by the two knives; neither of these knives cut"
or sever the sheet entirely across, but each cuts a portion, the last one operating
upon that part left intact after the first cutting operation, the object of thus
distributing the cutting operations being to enable tapes or bands to pass around
one or both of the cutting cylinders.
Thirdly. To the guiding of the forward end of the web after a sheet has been cut
from it by sending it first around the male cylinder carrying the cutting knife, and
then after that sheet has been severed from it around the female cylinder, into
;

page_text: which the knives enter when cutting; by this arrangement the forward end of the
web is guided on to first one and then the other of the cylinders. The cylinders
are each provided with vacuum chambers, which act alternately to hold (by air
pressure upon the forward end of the web) the paper first in contact with one
cylinder, and then in contact with the other cylinder, as the case may be.
Fourthly. To the use of condensing cylinders for storing up upon their periphery
a number of sheets, ten or more for example, and which sheets shall be piled one
upon the other. The diameter of these cylinders is equal to two, four, or any even
number of diameters of the inale or female cutting cylinders, and the inale and
female cutting cylinders are slightly larger than the type cylinders of the press.
By making the condensing cylinders of the size described there is aways a blank
space thereon free from paper equal to the length of a sheet in which to work the
strippers.
Fifthly. To a arranging strippers in connection with the condensing cylinders, so
that the pile of sheets is delivered at a tangent from the surface of the condensing
cylinders to tapes and flies properly arranged.
Sixthly. To fly frame having the fingers in line at the top, but curved across
their face, or across the line of the sheets in motion at the bottom or at the junction
of the fingers with the bar, this curvature being greatest at the bottom, and
gradually decreasing to a straight line at the top, the object being to keep the
sheets bent across the line of motion while running down on the fly, thus preventing
their tendency to curl during their passage through the air.
Seventhly. To the locating of the condensing cylinders and the fly franes, so
that the top sheet of the pile on the condensing cylinder may be delivered next to
the fly frame, this sheet therefore being the upper one when the pile is delivered on
the table by the movement of the fly frame; the result of this arrangement being
that the sheets when stripped from the condensing cylinders have a tendency
towards the fly frame rather than away from it.
Eighthly. To a cam having the thrust portion of its surface occupied by a spring,
which elastic portion acts to give to the fly frame an easy and springy action when
setting in motion towards the table the sheets received from the condensing
cylinders.
Ninthly. To the use of a pair of swivelling rollers between the feeding rollers
and the cutting device around which the paper passes in the forin of a letter S,
these rollers being swivelled to allow for the greater speed of the delivery, thus
keeping the paper stretched. These rollers come back to their normal position
whenever a sheet is severed from the web, and draw the forward end of the web
away from the rear end of the severed or preceding sheet, thus ensuring a perfect
separation of the sheet froin the web.
Tenthly. To a peculiar construction of packing joint between the air conducting
journal and the vacuum chamber of the revolving male and female cutting cylinders.
This packing is composed of a brass ring which revolves with the cylinder, and
has air passages formed through it; overlying this ring is a leather washer which
is attached to the cylinder, and prevents the entrance of air to the vacuum
chamber.
Eleventhly. To an arrangement of strippers, tapers, and fly frame that will
permit of the delivery of the accumulated pile of sheets from the condensing
cylinders to the fly frame in such manner that the sheet which was on the top of
the pile upon the condensing cylinder is delivered to the fly frame next to the
fingers thereof.

County of Middlesex, Mechanical Draughtsman. "IMPROVED DELIVERY APPARATUS
FOR WEB PRINTING PRESSES." A communication from abroad by Andrew Campbell,
of Brooklyn, in the State of New York, United States of America.
This Invention relates to a delivery apparatus to be attached to a web perfecting
printing press, which delivery separates the web into sheets, and deposits the sheets
one upon the other in one or more piles.
This Invention relates,--
Firstly. To a delivery apparatus in which the web is severed into sheets, which
delivery apparatus runs slightly faster than the press in which the web is printed,
the object being to keep the paper free from wrinkles, and also to keep the proper
tension despite the slight variations of the speed of the paper's passage through the
press, due to the varying thickness of the plates or the condition of the paper.
Secondly. To the cutting of the web into sheets. This is effected at two operations
by the use of two cylinders and a revolving frame carrying a knife, one of the
cylinders also being provided with a knife, and the remaining or female cylinder
containing the opening into which first the revolving knife and then the knifo
carried by the cylinder enters to cut the paper, the opening in the female cylinder
therefore being entered alternately by the two knives; neither of these knives cut
or sever the sheet entirely across, but each cut a portion, the last one operating
upon that part left intact after the first cutting operation, the object of thus
distributing the cutting operations being to enable tapes or bands to pass around
one or both of the cutting cylinders.
Thirdly. To the guiding of the forward end of the web after a sheet has been cut
from it, by sending it first around the male cylinder carrying the cutting knife, and
then after that sheet has been severed from it around the female cylinder into.
which the knives enter when cutting. By this arrangement the forward end of the
web is guided on to first one and then the other of the cylinders. The cylinders'
are each provided with a vacuum chamber, which chambers act alternately to hold
(by air pressure upon the forward end of the web) the paper first in contact with
one cylinder, and then in contact with the other cylinder, as the case may be.
Fourthly. To the use of collecting or condensing cylinders for storing up upon
their periphery a number of sheets (ten or more for example), and which sheets
shall be piled one upon the other. The diameter of these cylinders is equal to two,'
four, or any even number of diameters of the male or female cutting cylinders, and
the male and female cutting cylinders are slightly larger than the type cylinders of
the press. By making the condensing cylinders of the size described there is,
always a blank space thereon free from paper equal to the length of a sheet in
which to work the strippers.
Fifthly. To arranging strippers in connection with the condensing cylinders, so
that the pile of sheets is delivered at a tangent from the surface of the condensing
cylinders to tapes and flies properly arranged.
Sixthly. To fly frames having the fingers in line at the top, but curved across
their face, or across the line of the sheet's motion at the bottom, or at the junction
of the fingers with the bar, this curvature being greatest at the bottom, and
gradually decreasing to a straight line at the top, the object being to keep the
sheets bent across the line of motion while running down on the fly, thus preventing
their tendency to curl during their passage through the air.
Seventhly. To the locating of the condensing cylinders and the fly frames so that
the top sheet of the pile or the condensing cylinder may be delivered next to the
fly frame, this sheet therefore being the upper one when the pile is delivered on the
table by the movement of the fly frame, the result of this arrangement being that

page_text: the sheets when stripped from the condensing cylinders have a tendency towards
the fly frame rather than away from it.
Eighthly. To a cam having the thrust portion of its surface occupied by a spring,
which elastic portion acts to give to the fly frame an easy and springy action when
setting in motion towards the table the sheets received from the condensing
cylinders.
Ninthly. To the use of a pair of swivelling rollers situate between the feeding
rollers and the cutting device, around which rollers the paper passes in the form of
a letter S, these rollers being swivelled to allow for the greater speed of the
delivery, thus keeping the paper stretched. These rollers come back to their
normal position whenever a sheet is severed from the web, and draw the forward
end of the web away from the rear end of the severed or preceding sheet, thus
ensuring a perfect separation of the sheet from the web.
Tenthly. To a peculiar construction of packing joint between the air con-
ducting journal and the vacuum chamber of the revolving male and female cutting
cylinders.
Eleventhly. To an arrangement of strippers, tapes, and fly frame that will
permit of the delivering of the accumulated pile of sheets from the condensing
cylinders to the fly frame in the path indicated in the Drawings.
Referring to the accompanying Drawings,
Fig. represents a longitudinal vertical section of my delivery attachment.
Fig. 2 is a cross section on the line X, X, of Fig. 1, with the cylinder K removed.
Fig. 3 represents a longitudinal section of one of the two cutting cylinders; and
Fig. 3a is a transverse section of the same.
Fig. is a view of one of the cains used to operate the fly frame.
Fig. 5 is a view shewing the notion and the arrangement of the tapes and fixed
guards. The delivery apparatus is intended for attachment to a web perfecting
press severing the web into sheets, and depositing these sheets one upon the other
in an orderly and regular manner.
The combined delivery and cutting arrangements shown in Fig. 1 are driven
from one to two per cent. faster than the web perfecting press to which it is to be
attached, special devices being arranged in the delivery to allow for this increased
speed, as will be hereafter more fully explained. This is done to make up for the
varying speed of the web's passage through the press, that is the increased Lumber
of turns of the press makes a corresponding increase in the speed of the delivery,
but the variation of speed provided for by making the delivery run faster than
the press is due to varying thickness of the plates and to various other causes, the
speed of the web's passage at like speeds of the press not being always precisely the
same, which variation if not allowed for will cause the paper to " bag" between
the delivery and press or be broken by too great tension.
'
Referring to Figure 1, the web of paper B coming from the press is delivered
around and between the rollers A, A¹, the roller A being driven by friction gear,
and the lower one A being driven by contact with the roller A. The web B
passes around the rollers A and A¹, forming a letter S during its passage. From
these rollers the web B passes around the swivelling rollers C and C₁, here also
forming a letter S during its passage. The rollers C, C, are arranged to swivel,
that is, the roller C can move a short distance toward the roller A', and when this
takes the roller C¹ moves a corresponding distance away froin the roller A',
thus shortening the distance that the web E has to travel, and allowing for the
increased speed of the delivery apparatus, keeping a continual strain upon the
paper and preventing wrinkles or folds. The rollers C and C₁ are arranged with a
spring, so that they will, when the cutting or severing operation takes place,
suddenly draw back or retract to a slight extent such part of the web B as is
between them and the cutting cylinders; thus as each sheet is severed the increased
speed of the delivery is allowed for, the web B is not too severely strained, and a
short space is left between the forward end of the web and the back end of the
sheet severed from it.

page_text: At D, Figures 1 and 2, is shown a rotating frame, which, if desired, might be a
cylinder, carrying portions of a blade or knife rigidly attached to the revolving
frame D, as seen at d, Figures 1 and 2; this knife d does not extend entirely,
across the frame D, but is as broad as, or a little broader than, the web, and is in
sections having openings in it, as seen in Fig. 2, so that when it operates upon
the web the cut does not extend entirely across, but only about three quarters, or a
little more, of the breadth of the web B is severed, leaving the web B attached by.
an uncut portion to that part which is between the cutting cylinders. The knife d,
when cutting the web, which it does at every revolution, penetrates into the femalo.
cutting cylinder E, which has a groove running its entire length. The web B
next passes down between the cylinders E and F, when the portion left uncut by
the knife d is operated upon, and the sheet is severed entirely from the web by a
knife carried in the male cutting cylinder F, as shown at f, on Figs. 1, 2, and 3.,
The knife or blade f does not extend the entire length of the cylinder F, but is, like,
the knife d, in sections, as seen at Figs. 2 and 3, being arranged to cut the:
portions left uncut by the knife d, and thus complete the separation of a sheet
from the web B, the separation being ensured by the swivelling rollers cand c¹
drawing back slightly the end of the web after it has had a sheet cut from it by.
the knifof. The knife and the knife f both cut into the same slit or groove in
the female cylinder E, the knife d operating first and the knife ƒ last.
:
The object of performing the severing or cutting in two operations is to enable
tapes to be used around the cylinder F, parts of the cylinder F from which no.
knife projects being occupied by tapes, as seen in Fig. 3, at g, where the spaces
for the tapes are shown, the parts of the paper coming over these tape spaces.
having already been severed by the knife D in the revolving fraino D. Thus, not.
until the paper has reached nearly tho point of nearest contact of the malo.
cutting cylinder F and the female cutting cylinder E is it severed entirely across.:
The cylinder E and the cylinder F are both provided with vacuum chambers as at G
and H which communicate with an air pump, and by which means a vacuum is:
produced therein.
Referring to Fig. 3, the chamber II is shown, and also the small holes which:
open from the chamber FL through to the surface of the cylinder, as at h¹. These
openings are also shown at Fig. 1 in both cylinders, and are indicated by dotted
lines as at hand g³. The openings or air passages are in the cylinder F, just in.
the rear of the knife or blade f, and in the cylinder E are just in the rear of the
slot or groove into which the knives enter in cutting. The air passages gland h¹ aro
controlled by a valve placed in the cylinders, so that the vacuum chamber of either:
of the cylinders can draw air into it when the valves are properly operated, and:
will at such time hold the paper by the air pressure upon it forcing it on to the
air passages:
After describing the operation of the machine I will refer to Fig. 3,
and more particularly describe the method of operating such valves. Supposing:
now the end of the web B to be thus held by the vacuum in the cylinder F, the
vacuum chamber in the cylinder E being cut off by the closing of its valves from
the outside air, the paper will then follow the cylinder E in its rotation, as indi-
cated by the arrow, and will be thus held till it is caught by tapes and carried'>
around the roller I and deposited upon the condensing cylinder K, covering up one:
half of the periphery or circumference of the condensing cylinder, being held thereon.
by the appropriate tapes. While the paper was passing around the roller I and
being received on the cylinder K the knives D and F had severed or cut it first
partially and then wholly off from the web, leaving it in the form of an independent.
sheet, in which form it is received on the condensing cylinder K. At the moment.
the sheet was completely severed the then end of the web B was firmly held upon
the cylinder E, being pressed by the air pressure over the air passages g, these:
passages then being in free communication with the vacuum chamber G of the.
cylinder E, while the air passages of the cylinder F are closed by their valve:
from all communication with the vacuum chamber H. The end of the web B will:
therefore move around with the cylinder E, and will be guided by the appropriate:

page_text: devices when the vacuum has ceased to retain it. The end of the web will pass
around the cylinder L, and from there will be deposited upon the other condensing
cylinder M, which cylinder is exactly like the cylinder K, and to which the sheet
will bear the same proportion.
While the end of the web was passing around the cylinder L the cutting operations
take place, leaving it a free sheet to be deposited upon the condensing cylinder M.
At the moment this sheet is severed the end of the web B will be between the
cutting cylinders, and will by the vacuum apparatus already described be conducted
around the cylinder F on its way to the condensing cylinder K. Thus by alter-
nately opening the vacuum chambers by the valves placed in their respective air
passages the forward end of the web is and consequently the sheets are alternately
carried or guided first to the condensing cylinder K, and then to the condensing
cylinder M; thus alternately the two condensing cylinders receive sheets which lie
one upon the other. After the condensing cylinders have received the desired
number of sheets, say ten on each cylinder, the entire number is removed from the
cylinders by strippers, and delivered in two piles by the two fly frames. The piles
of sheets are removed from the cylinders M and K by the two sets of strippers N
and O, as seen in Figures 1 and 2. The strippers, of which there are any desired
number, ten being shown in the Drawings, are carried by shafts N and Ŏ parallel
to the condensing cylinders. The upper ends of the strippers are arranged to
penetrate into grooves made around the condensing cylinders, and they will thus,
when moved towards the cylinders, allow the entire piles of paper to slide off from
their respective cylinders in a tangential direction. The strippers, or at least their
upper ends, are kept away from the cylinders while the paper is being accumulated
thereon, and when the proper amount has accumulated the strippers are moved
toward the cylinders, and into the circumferential grooves thereon, thus getting
under the accumulated pile of paper and removing it. The diameter of the
cylinders M and K is an even multiple of the diameter of the cutting cylinders E
and ; this gives time to move the strippers towards the cylinders, the time occupied
in making half a revolution being amply sufficient. The strippers N are shown
in the position which they occupy when removing the paper from the condensing
cylinder BI, while the strippers O are in the position occupied when the sheets are
being accumulated on the cylinder K, and the stripper in this position is serving as
a bridge. When the strippers N or O operate the accumulated piles of sheets are
slidden downward over the strippers towards the fly frames P and Q.
'
•
It will be noticed that the arrangement of the fly frames P and Q is such in
relation to the condensing cylinders that the sheet which was on top of the pile
upon the condensing cylinder is delivered to the fly frame next to the fingers thereof,
which arrangement assists the proper delivery of the sheets to the fly, giving the
entire pile a tendency towards the fly frame rather than away from it. The angle
at which the fly stands in relation to the line of delivery over the back part of the
strippers also ensures the proper transfer of the sheets from the cylinders over the
strippers to the fly frame.
To provide against the tendency of the sheet to bend or double up when running
downward along the fly frame the frame is made of a peculiar shape, which as the
sheets pass downwards bends them across the line of motion. The shafts or rods to
which the fly fingers are attached have such fingers connected with them, not in a
straight line parallel with the rod's axis, but in a curved form, as shown at Q, in
Fig. 2; thus a line drawn across the set of fingers would be a bow or curved line,
and it would be across the line of motion of the sheets when being received by
the fly frames from the condensing cylinders.
At the top of the fly frame the fingers are straight, being all in a line with one
another, the transverse curvature gradually increasing from nothing at the top of
the frame to a maximum at its bottom. Thus when the sheets are received by the
frame they are flat or straight across the line of motion, and as they slide down
the fly the pile gradually becomes curved across the line of motion, assuming the
shape of the fly frame. This curvature in one direction has a strong tendency to

page_text: prevent curvature taking place in another direction, and therefore if the sheet
or sheets bend or double up in running down the fly such bending or doubling up
would be resisted by the transverse bend or curve already given to cach and all of
the sheets in the pile.
The fly frames are started by a cam of peculiar construction through the ordinary.
connecting rods and cranks, which latter are so simple and well understood that.
I will not attempt to describe them, neither have I thought it necessary to illustrate
them in the Drawings; but I will describe the cam which is used. Fig. 4 is a
plan view of such can. R, R, shews the positions of the crank pin, or pin through
which motion is transmitted to the fly frames. The pin when at R is just about to.
start the fly frames, and as the can turns, as is shewn by the arrow, the pin R is
ncted upon not by a rigid thrust portion of the cam, but by the spring portion S,
which bends or yields to within certain limits in proportion to the resistance, thus
more easily and gradually drawing the pin R in towards the cam's centre. As the
pin travels along the thrust portion (a spring S) the fly frame begins to fall by
gravity alone, and the spring simply has to increase very slightly its velocity, which
it easily does; the pin passes off the spring as at R', and then moving around in
the groove T to return the fly to its upright position. This provides for more rapid
working than could be effected by using a cam rigid in all its parts. At V and U
the piles of paper are delivered by the fly frames, ten sheets in this case being
deposited at each vibration of the frame, which frames are shown as acting alter-
nately. It is possible that this delivery apparatus may be used with but one.
condensing cylinder, and of course with but one fly frane. In this case to get
the sheets perfectly in place upon the condensing cylinder they would have to bo.
carried after leaving the cutting cylinders E and F different distances, that is, onc
sheet might go around the roller L, and then the next sheets, or those which started
around the cylinder F, would have to travel a greater distance, or in some way be
delayed in their passage to the condensing cylinder, else they would be deposited.
on this cylinder in such relation one to the other as to leave an insufficient space
clear of paper, in which case the strippers would have to be thrown in towards the
cylinder so quickly that the operation would be unsatisfactory, and the benefit
would be lost which is now gained by having the condensing cylinders so much.
larger circumferentially than the length of the sheet.
With but one condensing cylinder the fly frame would bear the saine relation to
it as the fly frames now bear to their respective cylinders.
Referring to Fig. 3, I will now explain more fully the construction of the cutting
cylinder, which explanation will serve also for the cylinder E, which is the
counterpart of the cylinder F, except in having a groove where the other one has a
fixed blade or knife. The vacuum chamber H with its air passages through the
metal of the cylinder are clearly shown in Fig. 3, and in the transverse section Fig. 3a.,
These air passages are provided with valves, or rather one long valve controls them
all this valve and the leather facings on each side of it is shown at e. It will be:
seen that it slides in the properly formed cavity made in the metal of the cylinder,.
which cavity is lined on each side with leather, and the valve has through it holes
or openings, which when brought in line with the air passages in the cylinder leave
such passages open, and when the valve is moved obstructs such passages.
On the.
shaft Y which carries the cylinder F there is a gear wheel and cam m, but the
cam and gear wheel are free to turn on the shaft, and are driven by a separate
wheel from that which drives the cylinder F.
The gear is so driven that the cam m attached to it operates to open and close
the valve e only at every other turn of the cylinder F. The piece Z does not turn
but remains stationary, and communicates with the vacuum chamber and with the
air pump through the downwardly projecting pipe. At a is the packing which.
prevents the air entering the vacuum chamber; it is composed of a brass ring
occupying loosely a space between the metal of the cylinder I and the stationary
piece Z, which ring revolves with the cylinder. Through this ring air passages are
formed. In the outside of the ring a leather washer rests, being attached to the .

page_text: cylinder F by screws covering the ring and resting upon part of the piece Z. When
the vacuum is formed in the chamber and passages thereto the air tends to pass
inward through the holes in the brass ring, and of course is prevented by the
leather which is forced by the air pressure against the surface of the ring as well as
against that part of the piece Z on which it rests, forming a most effective packing,
and being readily renewed by screwing on a new ring of leather.
:
Fig. 5 is a Drawing shewing the tapes and their arrangement, and the arrows.
indicate their motions. The two strippers N and O are shown, which strippers
have been already described, but it has been omitted to state that these strippers
act while the sheets are being accumulated on either of the condensing cylinders as
guards, preventing the accumulated sheets from flying off by centrifugal force, which
force is thus allowed to act when the strippers are moved to deliver the sheets. At.
the upper part of Fig. 5 two bridges are shewn for guiding the paper, and at the
upper part a bridge is also shown which acts as a continuation of the tapes.
The two limiting rollers and in the Fig. 5 hold the tapes against the centri-.
fugal action of the accumulated sheets, which force would otherwise cause the
delivery of the pile of paper over the back of the stripper prematurely, or before.
the strippers were moved in towards the condensing cylinder, the springing of the
tapes having to be thus resisted. The sheets will accumulate upon the condensing
cylinders till they are delivered to the strippers, therefore tappets or other equivalent
devices are arranged to operate the strippers N and O after the desired number of
sheets have been accumulated.
