1, HENRY P. FEISTER, of Philadelphia, Pennsylvania, U.S.A., Mechanical
Engineer, do hereby declare the nature of said invention for IMPROVEMENTS IN
PRINTING AND BINDING MACHINES, to be as follows :-
My invention has reference to machines for printing and binding pamphlets or
books direct from a roll of paper; and consists in certain improvements all of which
are fully set forth in the following specification.
The object of my invention is to make in an automatic manner a large number of
books from a roll of paper and to accomplish this object the paper is required to go
under the following operations. As the paper web passes into the machine the book
sheets are cut off prior to printing, and are then printed first on one side and then
upon the other in the manner hereinafter set forth, and after being printed upon both
sides the said book sheets are assembled, sheet after sheet on top of each other, and in
perfect register and folio. These sheets in the act of being assembled are pasted
together down their central margin and the book so formed is secured to its cover and
the entire assembled sheets and cover are folded through their center margin and then
subsequently trimmed where a particularly nice finish is required.
In carrying out my invention I provide two segmental impression cylinders and one
segmental type form cylinder, the two former working in contact with and cog-geared
to the latter and rotating in the same direction at point of contact so that one prints
from alternate type forms and the other prints from the type forms omitted by the
first. With these I provide suitable feed guide and cutting cylinders which perforate
the sheet transversely across and feed it to one of the impression cylinders at a rate
of speed equal to one half that of the impression surfaces upon said cylinder, but its
feed is so timed that the edge of the sheet will come in line with the forward advancing
edge of the impression surfaces where it is gripped by suitable automatic nippers
fitted to and working with the forward edge and carried around between the said
impression surfaces and the type form cylinder segments. If the sheet was wholly
cut from the continuously traveling web there would be difficulty in its proper delivery
to the nippers as said nippers could not catch the paper till they had passed and
descended beyond the cutting cylinders a distance equal to the length of the sheet
owing to the different velocities of travel of said cylinder and sheet. It would be

page_text: impracticable to rely upon the nippers holding the sheet so as to break or detach it from
the web. To accomplish this result I provide a sheet detacher consisting of a series of
pins arranged at right angles to a revolving shaft and adapted, during their revolution,
to work in contact with the advancing or leading edge of the impression surfaces of the
impression cylinder and thereby at stated intervals nip the sheet and break it from the
web, and at the same time instant therewith the nippers close upon the leading edge of
the sheet and it is carried forward in perfect register with marginal allowance to meet
the forms on the segmental form cylinder. After the sheet is carried between the type
form or printing cylinder and the first impression cylinder it is carried around and
transferred by a suitable transfer device such as set out in letters patent No. 9571 and
dated August 11th 1885 to the second impression cylinder which is revolving in the
same direction as that of the first impression cylinder and the nippers upon said
second impression cylinder close upon the tail end of the sheet, while the nippers
upon the first mentioned cylinder open to free the forward end of the sheet. It will
now be seen that what was before the leading edge of sheet now becomes the tail i.e.
reversed in its motion so that the printed face of the sheet is now turned down upon
the second impression cylinder, and as it is carried between the impression surface
and the type form cylinder the opposite or reverse side will be printed. The sheet
now being printed upon both sides, it is carried around the lower hemisphere of
said second impression cylinder and up and delivered to an assembling device located
at the rear of the machine.
The transfer device consists essentially of a hinged frame or tympan the rear end
of which swings out at the proper time through the agency of cam devices so as to
throw the tail end of the sheet within reach of the nippers upon the second impression
cylinder.
The type form cylinder has a continuous series of type forms about its circumference
which may be either curved or flat and receive ink from stationary inking rolls of any
of the well known constructions. When curved type forms are used then the type
form beds or segments to which they are secured are arranged rigidly upon the
cylinder their curvature being the same as the pitch curve of the said cylinder; but
when flat plates are used then these beds are pivoted in such a manner that they may
rock slightly so that each portion of the type surfaces may at the instant of printing
be brought in line with the pitch circle and thereby have all the effect of a curved
plate. This is accomplished by providing the said type beds with bearer plates on
their ends which shall run in contact with like curved surfaces on the impression
cylinders the face of said bearer plates being as tangents to the pitch circle.
The type form beds or segments are adjustably pivoted in this latter instance and
held in position by suitable springs which may be either of metal or rubber and are
provided with devices whereby their outward or radial adjustment may be regulated so
as to insure the requisite degree of printing pressure. As constructed these type
form beds may be made rigid, or adjustable to suit curved or flat type forms.
The type form beds or segments are made rectangular in shape and are provided
upon each end with journal lugs or studs by which they are held through the agency
of suitable links to a pair of wheels or spiders which wheels are adjustably secured
upon and between the gear-wheel and blank wheel forming the two outer walls of the
type form cylinder. The type form gear meshes with the corresponding gears upon
the impression cylinders and while it is found in practice that a single set of these
gear wheels and a set of blank wheels are sufficient yet it is evident that the blank
wheel may also be a gear wheel. Both of these wheels are secured firmly upon a
shaft and the pair of spiders or type form carrying wheels are. supported upon the
same shaft and adjustably clamped by means of bolts or slots to the said gear and
blank wheels preferably near the periphery whereby said spiders with their type forms
may be adjusted back and forth in the pitch circle. From this it will be seen that the
internal wheels or spiders and the segmental type form beds are adjustable either with
or against the direction of the travel of the type form cylinder gear and independently
of the position of the teeth in same. This adjustment is very important as it is by
this means that books of different sizes are enabled to be printed on the same machine.

page_text: These type form ocos are provided WITH a SIO extending almost from end to end
through which the form-clamps pass and are made adjustable laterally upon the bed.
These clamps are provided with pins or points upon their sides adapted to catch or
hold the type forms down upon the beds. These clamps project through to the under-
side of the bed and are provided with enlarged portions through which the clamping
bolt passes. One end of this clamping bolt is made in two parts one part of which is
screwed into one end of the bed and is connected to the other part by a right and
left hand screw threaded-coupling so constructed that upon being turned the
clamping bolts will be drawn together. The free end of the last mentioned bolt is
provided with a head which draws upon the end clamp and this through the
mediation of the type form presses upon the next clamp and so on clamping all
of the type forms firmly in position upon the bed. As many or few of these
adjustable clamps may be used as are desired as they are capable of being placed
upon and removed from the bed at will. The construction of the type-form cylinder
is novel in every particular admitting of lateral adjustment of the clamps to hold type
forms of different widths or also of different lengths, to suit books of different sizes.
The maximum speed may be obtained as each cylinder revolves constantly in the
same direction at point of gear mesh.
The advantage of the above mentioned adjustable features will be readily appreciated
when it is understood that the only limit to the size of the book or books capable of
being printed upon this machine is the maximum width and length or linear
dimensions of the type form beds or impression surfaces, as each impression surface
may print laterally one or more book sheets at one time as desired and as governed
by the previous adjustment. The sheets after being printed upon both sides may be
delivered upon a fly frame and used as circulars or bound in any manner desired;
but I prefer to assemble them upon an assembling device and then after the required
number of sheets have been assembled, deliver them to a folding mechanism. The
assembling device consists of a skeleton frame revolving in unison with another or
pasting fountain frame, the former of which is provided with a series of adjustable
spring band sections to support the assembled sheets, and further with two sets of
nippers, one of which sets is for the purpose of holding the leading edge of each sheet
as they assemble on each other while the other of which sets is for the purpose of
taking and holding the leading edge of the sheet from the impression segments of the
second impression cylinder as delivered until the first mentioned set of nippers is
withdrawn from under and placed on top of the sheet. The assembled sheets are
successively clamped upon a radially movable bar supported upon springs, which with
the forward edge of the sheets collected is depressed by a cam on each side connected
with a pin-bar (the purpose of the pin-bar to distribute the buckles or wrinkles in
each sheet as they assemble on said skeleton) as well as to hold the leading edge of
the sheet close to the radial bar on the assembling frame so as to insure the retaining
nippers on top of said sheet as the bar rises, thereby allowing at one point in the
revolution of the assembling skeleton a proper working of the holding nippers. These
nippers are worked by suitable cam devices so as to operate with each revolution of
the skeleton frame, to assemble and hold the leading edge of one or more sheets; and
they are so arranged that after a given number of sheets are assembled a suitable cam
operates to throw them entirely out of action whereby the sheets are received upon
the fly frame which has been tipped sufficiently to pass under the said sheets as their
leading edges advance toward it. As the leading edge of each sheet is taken off the
impression segments of the second impression cylinder the sheets naturally lie on top
of the retaining (or holding) nippers, and said retaining nippers by suitable cam
mechanism are actuated to withdraw from under the sheet just prior to the depression
of the radially moving bar and to again close in the curvature of the pitch-circle of
the gears (by which the assembling skeleton is driven) while the said moving bar is
depressed. As the moving bar again rises it clamps the sheet or sheets against the
retaining nippers. The object of this radially moving bar is to allow the withdrawing
of the retaining nippers from under the sheets and their passage above the same; and
this is attained by causing the sheet to move down with the said bar after the

page_text: retaining nippers have been drawn back, so that upon the advance of said nippers the
retaining part comes over the leading edge of the sheet, and when the said bar again
rises it clamps the sheet against the said retaining nippers.
The leading ends of say four of the spring bands of the assembling device are left.
loose in a measure compared with the others, so that they will press the leading edge
of the sheets against the like edge of the impression cylinder segments in order to
prevent the sheets slipping during action of delivery of sheet to the assembling
device as for an instant of time the sheet at this period is not in the custody of
any nippers.
The upper of said assembling devices is provided with an air-tight paste fountain
arranged to automatically feed the pastę with each revolution to place upon the last
sheet assembled as aforesaid a transverse line of paste whereby the successive sheets
are pasted together. Said paste fountain is adjustable with the radii of pitch circle of
the gears by which the paste fountain and assembling-skeleton revolve in unison this
being necessary in order to paste books of different sizes, they always being pasted
down the center or folding margin. After the assembled and pasted sheets are
delivered to the fly frame they are laid upon the table upon which the back or cover
has been previously placed or inserted and the upper or exposed line of paste attaches
the covers to the assembled and pasted sheets. The paste fountain is carried by one
of the skeleton frames above mentioned may be counterbalanced to make it run
smoothly, and the paste may be fed to the fountain while the machine is running. The
paste fountain consists of an air tight receptacle having an orifice opening upon the
pitch circle and furnished with two preferably adjustable plates between which
the paste roller is intermittently rotated by suitable cam or eccentric devices one
of which plates lets out the paste the other scrapes it off whereby a limited amount of
paste is brought to the face and applied to the book center-margin or folding line with
the reception of each new sheet avoiding all excess which would tend to cause trouble
in the proper binding of the books: This paste fountain as aforesaid is adjustable on
the pitch circle and about the center of the semicircle of the skeleton frame to which
it is attached whereby it may be caused to apply paste on the folding line of books of
different sizes. This is necessary where it is desired to print books of different sizes
on the same machine. After the pasted sheets have been delivered by the fly frame a
folding knife descends folding the sheets and cover into a book form, and which folded
sheets may be run between trimming knives, or be subsequently cut. If the machine
is made of sufficient width two or more pamphlets or books may be made and formed
end to end and may be subsequently cut apart. The bound signature after passing
through the folder is received by a packer which presses each successive book back-
ward in the rear of suitable spring pawls which retain them in the desired position
and clear of the book next entering.
The second impression cylinder receiving the printed sheets printed side down are
apt to have their tympans more or less inked by the reception of successive printed
sheets and the consequent pressure to which they are subjected. To prevent
blurring of sheets from this case 1 provide a movable tympan or make-ready web and
a suitable device for moving it automatically with each impression whereby cach
successive sheet is received upon a different portion thereof.
The roll of paper is supported upon a carriage or frame which is pivoted to a bed
upon a vertical center the object being to allow the paper to feed uniformly to the
feed and perforating cylinders and thereby overcoming defects due to the differences
that is sometimes found between the lengths in a given distance of the two lateral
edges of a roll of paper.

page_text: 1, HENRY P. FEISTER, of Philadelphia, Pennsylvania, U.S.A., Mechanical Engineer,
do hereby declare the nature of my invention for IMPROVEMENTS IN PRINTING
AND BINDING MACHINES, and in what manner the same is to be performed to he
particularly described and ascertained in and by the following statement :-
My invention has reference to machines for printing and binding pamphlets or
books direct from a roll of paper; and consists in certain improvements all of which
are fully set forth in the following specification and shown in the accompanying
drawings which form part thereof. The object of my invention is to make in an
automatic manner a large number of books from a roll of paper, and to accomplish
this object the paper is required to go under the following operations. As the paper
web passes into the machine the book sheets are cut off prior to printing, and are then
printed first on one side and then upon the other in the manner hereinafter set forth,
and after being printed upon both sides the said book sheets are assembled, sheet after
sheet on top of each other, and in perfect register and folio. These sheets in the act
of being assembled are pasted together down their central margin and the book so
formed is secured to its cover and the entire assembled sheets and cover are folded
through their center margin and then subsequently trimmed where a particularly nice
finish is required.
In carrying out my invention I provide two segmental impression cylinders and one
segmental type form cylinder, the two former working in contact with and cog-geared
to the latter and rotating in the same direction at point of contact so that one prints
from alternate type formis and the other prints from the type forms omitted by the
first. With these I provide suitable feed guide and cutting cylinders which perforate
the sheet transversely across and feed it to one of the impression cylinders at a rate of
speed equal to one half that of the impression surfaces upon said cylinder but its feed
is so timed that the edge of the sheet will come in line with the forward advancing
edge of the impression surface where it is gripped by suitable automatic nippers fitted
to and working with the forward edge and carried around between the said impression
surfaces and the type form cylinder segments. If the sheet was wholly cut from the
continuously travelling web there would be difficulty in its proper delivery to the
nippers as said nippers could not catch the paper till they had passed and descended
beyond the cutting cylinders a distance equal to the length of the sheet owing to the
different velocities of travel of said cylinder and sheet. It would be impracticable to
rely upon the nippers holding the sheet so as to break or detach it from the web. To
accomplish this result I provide a sheet detacher consisting of a series of pins arranged
at right angles to a revolving shaft and adapted during their revolution to work in
contact with the advancing or leading edge of the impression surfaces of the
impression cylinder and thereby at stated intervals nip the sheet and break it from
the web, and at the same time or instant therewith the nippers close upon the leading.

page_text: edge of the sheet and it is carried forward in perfect register with marginal allowance
to meet the forms on the segmental form cylinder. After the sheet is carried between
the type form or printing cylinder and the first impression cylinder it is carried
around and transferred by a suitable transfer device such as set out in letters patent
No. 9571 and dated August 11th 1885 to the second impression cylinder which is
revolving in the same direction as that of the first impression cylinder and the nippers
upon said second impression cylinder close upon the tail end of the sheet, while the
nippers upon the first mentioned cylinder open to free the forward end of the sheet.
It will now be seen that what was before the leading edge of sheet now becomes the
tail i.e. reversed in its motion so that the printed face of the sheet is now turned down
upon the second impression cylinder, and as it is carried between the impression
surface and the type form cylinder the opposite or reverse side will be printed. The
sheet now being printed upon both sides, it is carried around the lower hemisphere of
said second impression cylinder and up and delivered to an assembling device located
at the rear of the machine.
The transfer device consists essentially of a hinged frame or tympan the rear end of
which swings out at the proper time through the agency of cam devices so as to throw
the tail end of the sheet within reach of the nippers upon the second impression
cylinder.
The type form cylinder has a continuous series of type forms about its
circumference which may be either curved or flat and receive ink from stationary
inking rolls of any of the well known constructions. When curved type forms are
used then the type form beds or segments to which they are secured are arranged
rigidly upon the cylinder their curvature being the same as the pitch curve of the
said cylinder; but when flat plates are used then these beds are pivoted in such a
manner that they inay rock slightly so that each portion of the type surface may at
the instant of printing be brought in line with the pitch circle and thereby have all
the effect of a curved plate. This is accomplished by providing the said type beds
with bearer plates on their ends which shall run in contact with like curved surfaces
on the impression cylinders, the face of said bearer plates being as tangents to the
pitch circle.
The type form beds or segments are adjustably pivoted in this latter instance and
held in position by suitable springs which may be either of metal or rubber and are
provided with devices whereby their outward or radial adjustment may be regulated
so as to insure the requisite degree of printing pressure. As constructed these type
form beds may be made rigid, or adjustable to suit curved or flat type forms.
The type form beds or segments are made rectangular in shape and are provided
upon each end with journal lugs or studs by which they are held through the agency
of suitable links to a pair of wheels or spiders which wheels are adjustably secured
upon and between the gear wheel and blank wheel forming the two outer walls of
the type form cylinder. The type form gear meshes with the corresponding gears
upon the impression cylinders and while it is found in practice that a single set of
these gear wheels and a set of blank wheels are sufficient yet it is evident that the
blank wheel may also be a gear wheel. Both of these wheels are secured firmly
upon a shaft and the pair of spiders or type form carrying wheels are supported
upon the same shaft and adjustably clamped by means of bolts or slots to the said
gear and blank wheels preferably near the periphery whereby said spiders with their
type forms may be adjusted back and forth in the pitch circle. From this it will be
seen that the internal wheels or spiders and the segmental type form beds are
adjustable either with or against the direction of the travel of the type form cylinder
gear and independently of the position of the teeth in same. This adjustment is very
important as it is by this means that books of different sizes are enabled to be printed
on the same inachine.
These types form beds are provided with a slot extending almost from end to end
through which the form-clamps pass and are made adjustable laterally upon the bed.
These clamps are provided with pins or points upon their sides adapted to catch or
hold the type forms down upon the beds. These clamps project through to the

page_text: underside of the bed and are provided with enlarged portions through which the
clamping bolt passes. One end of this clamping bolt is made in two parts one part of
which is screwed into one end of the bed and is connected to the other part by a right
and left hand screw-threaded coupling so constructed that upon being turned the
clamping bolts will be drawn together.
The free end of the last mentioned bolt is provided with a head which draws upon
the end clamp and this through the mediation of the type form presses upon the next
clamp and so on clamping all of the type forms firmly in position upon the bed.
As many or few of these adjustable clamps may be used as are desired as they are
capable of being placed upon and removed from the bed at will. The construction of
the type-form cylinder is novel in every particular admitting of lateral adjustment of
the clamps to hold type forms of different widths or also of different lengths, to suit
books of different sizes. The maximum speed may be obtained as each cylinder
revolves constantly in the same direction at point of gear mesh.
The advantage of the above mentioned adjustable features will be readily
appreciated when it is understood that the only limit to the size of the book or books
capable of being printed upon this machine is the maximum width and length or linear
dimensions of the type form beds or impression surfaces, as each impression surface
may print laterally one or more book sheets at one time as desired and as governed by
the previous adjustment. The sheets after being printed upon both sides may be
delivered upon a fly frame and used as circulars or bound in any manner desired; but
I prefer to assemble them upon an assembling device and then after the required
number of sheets have been assembled, deliver them to a folding mechanism. The
assembling device consists of a skeleton frame revolving in unison with another or
pasting fountain frame, the former of which is provided with a series of adjustable
spring band sections to support the assembled sheets, and further with
two sets of nippers, one of which sets is for the purpose of holding the leading
edge of each sheet as they assemble on each other while the other of which
sets is for the purpose of taking and holding the leading edge of the sheet
from the impression segments of the second impression cylinder as delivered
until the first mentioned set of nippers is withdrawn from under and placed on top of
the sheet. The assembled sheets are successively clamped upon a radially movable
bar supported upon springs, which with the forward edge of the sheets collected is
depressed by a cam on each side connected with a pin-bar (the purpose of the pin-bar
is to distribute the buckles and wrinkles in each sheets as they assemble on said
skeleton) as well as to hold the leading edge of the sheet close to the radial bar on the
assembling frame so as to insure the retaining nippers getting on top of said sheet as
the bar rises, thereby allowing at one point in the revolution of the assembling
skeleton a proper working of the holding nippers. These nippers are worked by
suitable can devices so as to operate with each revolution of the skeleton frame, to
assemble and hold the leading edge of one or more sheets; and they are so arranged
that after a given number of sheets, are assembled a suitable can operates to throw
them entirely out of action whereby the sheets are received upon the fly frame which
has been tipped sufficiently to pass under the said sheets as their leading edges advance
toward it. As the leading edge of each sheet is taken off the impression segments of
the second impression cylinder the sheets naturally lie on top of the retaining (or
holding) nippers, and said running nippers by suitable cam mechanism are actuated to
withdraw from under the sheet just prior to the depression of the radially moving bar and
to again close in the curvature of the pitch circle of the gears (by which the assembling
skeleton is driven) while the said moving bar is depressed. As the moving bar again
rises it clamps the sheet or sheets against the retaining nippers. The object of this
radially moving bar is to allow the withdrawing of the retaining nippers from under
the sheets and their passage above the same; and this is attained by causing the sheet
to move down with the said bar after the retaining nippers have been drawn back, so
that upon the advance of said nippers the retaining part comes over the leading edge
of the sheet, and when the said bar again rises it clamps the sheet against the said
retaining nippers.

page_text: The leading ends of say four of the spring bands of the assembling device are left
loose in a measure compared with the others, so that they will press the leading edge
of the sheets against the like edge of the impression cylinder segments in order to
prevent the sheets slipping during action of delivery of sheet to the assembling device
as for an instant of time the sheet at this period is not in the custody of any nippers.
The upper of said assembling device is provided with an air-tight paste fountain
arranged to automatically feed the paste with each revolution to place upon the last
sheet as assembled as aforesaid a transverse line of paste whereby the successive sheets
are pasted together. Said paste fountain is adjustable with the radii of pitch circle of
the gears by which the paste fountain and assembling-skeleton revolve in unison this
being necessary in order to paste books of different sizes, they always being pasted
down the center or folding margin. After the assembled and pasted sheets are
delivered to the fly frame they are laid upon the table upon which the back or cover
has been previously placed or inserted and the upper or exposed line of paste attaches
the covers to the assembled and pasted sheets. The paste fountain carried by one of
the skeleton frames above mentioned may be counterbalanced to make it run smoothly,
and the paste may he fed to the fountain while the machine is running. The paste
fountain consists of an air tight receptacle having an orifice opening upon
the pitch circle and furnished with two preferably adjustable plates between
which the paste roller is intermittently rotated by suitable cam or eccentric
devices one of which plates lets out the paste, and the other scrapes it off
whereby a limited amount of paste is brought to the face and applied to
the book center - margin or folding line with the reception of each new sheet
avoiding all excess which would tend to cause trouble in the proper binding of the
books. This paste fountain as aforesaid is adjustable on the pitch circle and about
the center of the semi-circle of the skeleton frame to which it is attached whereby it
may be caused to apply paste on the folding line of books of different sizes. This is
necessary where it is desired to print books of different sizes on the same machine.
After the pasted sheets have been delivered by the fly frame a folding knife descends
folding the sheets and cover into a book form, and which folded sheets may be run
between trimming knives, or be subsequently cut. If the machine is made of sufficient
width two or more pamphlets or books may be made and formed end to end and may
be subsequently cut apart. The bound signature after passing through the folder is
received by a packer which presses each successive book backward in the rear of
suitable spring pawls which retain them in the desired position and clear of the book
next entering.
The second impression cylinder receiving the printed sheets printed side down are
apt to have their tympans more or less inked by the reception of successive printed
sheets and the consequent pressure to which they are subjected. To prevent blurring
of sheets from this cause I provide a movable tympan or make-ready web and a
suitable device for moving it automatically with each impression whereby each
successive sheet is received upon a different portion thereof.
The roll of paper is supported upon a carriage or frame which is pivoted to a bed
upon a vertical center the object being to allow the paper to feed uniformly to the
feed and perforating cylinders and thereby overcoming defects due to the difference
that is sometimes found between the lengths in a given distance of the two lateral
edges of a roll of paper.

Dis the main frame work of the machine and supports the two impression cylinders A
and 13 both rotating in the same direction but not in contact with each other, and the
type form cylinder with which both of the impression cylinders work; the organism
being such that the impression cylinder A prints from certain type forms of the
cylinder and those omitted by the said impression cylinder A are printed from by
the cylinder B substantially in the manner set out in letters patent No. 1865, and
granted to me April 18th 1882 also letters patent No. 9571 dated August 11th 1885,
but in this application I have substituted a chain or series of type beds in the form of
a cylinder. The impression cylinder A is provided with a series of impression
surfaces a separated by an equal distance, and the leading end of each of said
impression surfaces is provided with suitable paper clamping nippers G.
The roll of paper E is loosely supported upon a frame E which is allowed to
oscillate in a horizontal plane by means of a vertical pivot E2 formed in the base
plate E3 which in practice rests upon the floor. By this means inequalities in the
dengths of the edges of the paper web will not cause a dragging effect upon the feed
and cutting rolls F. The feed and cutting rolls consist of a roller F having per-
forating points or cutters f, and the roller F having notches or grooves into which
said perforating points or cutters project. These rollers are geared together by spur
gears F (see Figure 1) whereby they are caused to run in unison and perforate the
web of paper to form two sheets with each revolution. These rollers do not entirely
sever the sheet but simply put it in such a condition that it is easily broken or
B

page_text: detached from the web. The surface speeds of these perforating cylinders or rollers
is one half that of the impression cylinder A so that the leading edge of each successivo
sheet delivered to the impression cylinder shall coincide with the leading edge of each
of the impression surfaces a. These perforating rolls are driven by gears FF, the
former of which is secured to the impression cylinder A or its shaft A³. F³ is the
rotating shaft to which are secured a series of detaching pins and said shaft is
rotated by a gear A² which meshes with the teeth A of the impression cylinder A
(see Fig. 2). The object of this detacher is to catch at stated intervals the forward
edge of the sheet by pressing it against the impression cylinder, and for an instant of
time cause it to travel at double the velocity that it would otherwise have. The effect
of this is to break the sheet away from the web along the lines of perforations, and the
instant this is done the nippers & fly down and clamp the leading edge of the sheet to
the impression surface a. These nippers are secured to a cross rock shaft G₁ journaled
on the impression cylinder between the impression surfaces and has secured to its
outer end the pinion g which is rotated by a segmental lever G2 having roller g
which runs against the nipping and releasing cams for the purpose of oscillating the
segment to open or close the nippers. The nippers are normally kept closed by means
of a rod G³ and spring G connecting with the segment G the said springs opposing
the action of the camis. His the nipping cam and is secured to an arm H journaled
on the shaft of the impression cylinder, and said cam is adjustable in the arc of a circle
by means of a slot and bolts h passing through the main frame of the machine.
This cam H is so located that it opens the nippers fully to pass under the sheet per-
forating rolls and allow them to close quickly immediately upon the sheet being
detached as herein before described. The sheet so delivered to the impression cylinder A
is carried past the type form cylinder and receives an impression upon one side and is
then carried on until it comes directly opposite to the other impression cylinder B
when it is transferred by a suitable transfer device set out in letters patent No. 9571
above referred to. This transfer device consists essentially of a tympan I secured at
its leading edge of the impression surface a of the impression cylinder A. This
tympan is connected by a link near its middle and is swung out at the proper
instant by said link which is hinged to a lever I' secured to a rock shaft which rock
shaft is rocked by means of a lever 12, and reciprocating bar 13 having a roller
working in a stationary cam I'. This cam has but one operating part and that is so
located as to make the various tympans or transfer frames operate at one particular
place in the revolution of the impression cylinder. Each of the impression surfaces a
are provided with a similar tympan and mechanism to operate it, though for simplicity
and clearness only one such complete device is shown in Fig. 3. The instant the
tympan moves the tail end of the sheet over to the cylinder B the nippers G are
caused to release the leading edge of the sheet of paper by means of a releasing cam H
secured to a radial arm H³ journaled upon the axle A³ and made adjustable in the are
of a circle by means of the slotted link and bolt device H connecting with the main
frame of the machine. In addition to this adjustment the cam His adjustable by
means of a slot or bolt connection 2 to and from the center of the impression cylinder
to control the degree of opening of the nippers. The instant the sheet is thrown to
the cylinder B and is released by the nippers on the cylinder A it is caught by the
nippers G on the cylinder B, the tail end now becomes the leading end of the sheet
and the printed surface lies adjacent or next to the impression surface. The sheet is
now carried between the type form cylinder and impression cylinder B and its
reverse side is printed upon by one of the type forms omitted by the cylinder A and
after being thus printed upon both sides the sheet is carried around and delivered
to the assembling device M. The impression cylinder B is in all material respects
the same in construction as the cylinder A with the exception that it has no transfer
tympans. It is combined with similar cams H to operate the nippers to close upon
the forward or leading edge of the sheet and the releasing cam H2 to release the sheet
when in the act of being delivered to the assembling device. To prevent blurring
of the sheet when in the custody of the second impression cylinders B I provide
the impression surface thereof with movable make-ready webs which may be

page_text: intermittently wound from one roller B to another traveling to a slight extent with each
impression so that every time a fresh sheet is received upon the impression surface b
the inked portion thereof is received upon a different portion of the make-ready.
This make-ready web may be moved automatically in a large number of ways, that
shown in Fig. 3 consisting of a ratchet wheel & attached to one of the roller B' com-
bined with a stop pawl and a pivot pawl and lever actuating device B² which is
reciprocated with each revolution of the cylinder B by being brought into contact
with the stationary cam B. The type form cylinder C consists of the two main
wheels one or both of which may be provided with gearing to engage with the
teeth on the impression cylinders and thereby be caused to revolve in unison therewith,
and to the inner faces of the said main wheels are adjustably secured spiders or form
supporting wheels C₁ which are adjustable upon the shaft C³ to which the main wheels
are secured. The form wheels are adjustably bolted by means of the bolts e and
slots c to the main wheels near their periphery for the purpose of accurately adjusting
the relative position of the type forms with respect to the impression surfaces without
disengaging the main wheel or wheels of the form cylinder from the gears of the
impression cylinders, and further more this adjustment admits of a very small variation
in position of the type beds whereas the other would necessitate at least a movement
equal to the distance between the centers of two adjacent teeth. This adjustment is
extremely important as it is the means whereby books of different sizes may be printed
upon the same machine and enables the adjustment to be made with respect to the
leading edge of the sheet and thereby insure the impression to be properly located.
Care the type form beds and are connected to the wheel C by means of links or eye
bolts connecting at one end with lugs on the ends of the type form beds and at
the other end connected by nuts K² and a spring K' with a flange of the wheels C¹.
The spring K2 may be made of metal or simply a rubber washer. These links or bolts
perform a function of holding the form beds C in the proper radially adjustment so
as to keep the printing surface of the type form in a line with the pitch circle of the
impression and type form cylinders and thereby insure accurate and good printing.
To prevent the form beds from being forced toward the center of the form
cylinder provide bolts K³ having semi-cylindrical heads K* which fit into
corresponding recesses C upon the ends of the form bed and upon each side
of the lugs e, each bolt receiving a pressure from two adjacent form beds.
These bolts are guided through bearings K7 and are supported upon springs K
the tension of which may be adjusted by nuts K³. From this construction
(see Figures 4, 5, 6, 15 & 16) it is evident that the form beds will be free to rock so
as to bring every portion of the printing surface of a flat form at the instant of
printing into the pitch line or curved plane through the face of the impression
surface. To remove the pressure, necessary to rock these beds, from the type forms
I provide upon each end of the bed a hardened steel hearing plate which rocks against the
surface of the impression cylinders and causes these beds to rock in a manner to print
without undue pressure upon the type forms. If curved type forms such as indicated
in Fig. 6 be used then it is not necessary to rock the beds Cand in that case curved
bearer plates would be substituted for the flat or tangent plates as indicated in dotted
lines in Fig. 7.
In this case the springs K around the bolts K³ might be removed
and metallic tube sections K³ substituted therefor (see right band portion of Fig. 5)
which change would make the parts K³ rigid and by proper adjustment of the nuts K³
the adjustment of the beds could be made to a nicety.
It is evident that these details of construction might be modified in various ways
and yet attain the same results. I therefore do not limit myself to the specific devices
shown. As the bolts K and K³ are carried by the inner wheel C it will be perceived
that these beds are also necessarily carried by said wheels and are adjustable with
them. This method of construction enables the machine to be changed to make the
beds rigid or adjustable to suit curved or flat type forms as the case may be. These
beds are provided with a longitudinal slot through which the form clamps are
connected to a tension bolt located in the under part of the bed. These clamps A¹
are provided with teeth preferably bevelled with the incline face turned down so

page_text: that when they are pressed against the wooden side of the type forms the tendency.
will be to draw the said type form close to the bed. These clamps have a head /³ on
their lower parts through a hole of which the tension bolt passes. These clamps
are inserted from one end of the bed before the bearer is secured in place, and the end
clamp or the one last placed on is drawn up; against the end type form J2 and by
arranging the clamps and the type forms alternately as indicated in Figs. 4 and 8
they may be clamped firmly in position the clamping action being transmitted from
one to the other. To create the tension I make a bolt in two paris each of which
has a head one of which heads pulls against the end of the form bed and the other
of which head pulls against the last clamp, and these two parts of the bolt are
drawn together by a right and left hand coupling piece as shown in Fig. 8.
this it is seen that by turning the coupling all of the type forms may be clamped
securely to the form bed and by varying the number of clamps any number of sizes of
type forms may be used.
From
In a machine of this class it is evident that each type form on each bed may be
used to print a corresponding page in as many books, or if desired the sheets printed
from two or more such type forms may be used as signatures and ultimately bound
together into the same book. Thus for instance, a machine holding five type forms
upon each bed and having 16 beds would be capable of printing five books of sixteen
pages with each revolution, or one book of eighty pages; or if we have two beds to
each impression surfaces these figures will be doubled and it will thus be seen that the
capacity of the machine will be enormous.
L is the inking rollers for the form cylinder and are driven by a belt 7 passing
around a pulley L' secured to the shaft C3 of the form cylinder.
Jis the main drive wheel of band pulley from which power is transferred to the
machine by pinion J' meshing with the teeth B5 of the impression cylinder B. The
arrows on the different figures indicate the direction of travel of the various parts.
The sheets printed in the manner above described may be delivered by a suitable
fly frame or delivery apparatus and be used as circulars in the loose form or they may
be collected and bound in book form by a suitable apparatus now to be described.
The binding apparatus consists of two parts the assembling device by which the
sheets are assembled upon each other one after the other and are pasted together
down the center of their middle margins; and the folding device for folding the
sheets so collected and pasted. These devices are clearly shown in Fig. 1 and Figs. 15
to 28 inclusive. The assembling device M consists essentially of two skeleton frames
revolving in contact with each other, one of said frames M¹ being the assembling
cylinder while the other M² carries the paste fountain and applies the paste to the
sheets as they are successively assembled on the assembling frame. The assembling
frame is supported upon an axle or shaft M" to which is secured a series of arms M³.
To these arms are secured a corresponding series of flexible spring bands M* which
are curved around forming a semi-circle and giving the appearance to the frame of a
semi-cylinder. Diametrically opposite to the arms M³ is a radially moving changer
bar Ms adapted to move to or from the shaft M" and is pressed away from the said
shaft by rods Mo near each end, and springs M'. The ends of some of the bands M
are secured to brackets m¹ in turn bolted to the radially moving bar M³ so as to be
depressed with the said bar, while others of said bands have their ends m free as
indicated in Figs. 17 and 18 the purpose of which will be hereinafter set out. The
skeleton frame so formed revolves upon its axis M" and moves in unison by means of
gearing with the frame M² carrying the paste fountain and revolving upon an
axle O. The frame M is provided with the cams P arranged to be adjusted about the
axis by means of slots p and screws ¹. These cams are set so as to strike the
radially moving bar M once in every revolution and cause it to be depressed when
the retaining nippers are in the act of being shifted. Connecting these cams P, is a
cross pin bar P carrying a series of pins P longitudinally adjustable in the direction
of their length, and arranged radially with respect to the axis O. The object of these
pins is to cause the leading edge of the paper sheets to be held down upon the radially
moving bar in such a manner that any buckles formed thereon shall be pressed down

page_text: or distributed thereby reducing all wrinkles and buckles to a small size and insuring
the retaining nippers being freely passed above the leading edge of the sheet. The
frame M is provided with two sets of nippers, one set m² called the retaining nippers
and the other set m³ or receiving nippers. These two sets of nippers are respectively
secured upon rock shafts m and m² and are equal in number being arranged side by
side as shown in Figs. 16, and 17, the pins P¹ of the pin bar working between them.
The nippers m³ are designed to catch every sheet from the impression cylinder B just
as the nippers G of the impression cylinder are released by the delivery cam H
whereas the nippers m² are simply designed to hold the assembled sheets collected by
the action of nippers in while the said nippers m³ are raised in the act of catching the
leading end of a fresh sheet. The action of these nippers at this part of their move-
ment is clearly shown in Fig. 18. After a fresh sheet is assembled upon those already
resting upon the spring bands M, the said nippers M³ hold it till the next sheet is to
be received, merely opening and closing once in a revolution (except when delivering
the assembled sheets to the folder) and then when it is close to the impression
cylinder B. When the leading edges of the assembled sheets approach a vertical line
through the axis of the cylinder M the retaining nippers m¹ are drawn from under
the last assembled sheet and as the movement continues the cam P on the frame M²
depresses the radially moving bar with its assembled sheets as indicated in Fig. 19.
At this instant the retaining nippers m² are allowed to move back over the top of the
leading edges of the assembled sheets as indicated in Fig. 20 and as the cam P is
lifted from the radially moving bar the springs M² cause the said bar to move away
from the axis M and clamp the sheets between itself and the retaining nippers.
The retaining nipper shaft is caused to rock by means of a spring me so as to
normally close the nippers into operating position and when said nippers are to be
turned from under the last collected sheet his operation is performed through the
agency of crank m' having the roller which works in contact with the stationary
cam M³ see Figs. 17, 21, and 22. After the proper number of sheets have been
assembled and it is desired to discharge them to the fly frame by which they are
delivered to the folding portion of the machine the retaining nippers M are thrown
back a greater distance by means of a delivery cam MP connected to a lever M pivoted
at m to the main frame of the machine and combined with a spring me to throw the
cam M out of action; the free end of the lever M10 is connected to a link N guided
on the main frame by a slot n' and lug N2, and this link is provided on its end with a
roller with which one or more cams B' on the impression cylinder B (see Fig. 21)
work. When the cam B37 shifts the link N it raises the delivery cam M into the
position indicated in dotted lines Fig. 21 so that as the roller m³ for operating
the nippers travels around, its overhang runs upon the delivery cam and causes the
nippers to open to allow the delivery of the assembled sheets. The nippers M³ are
operated by a pinion and segmental gear similar to those upon the impression
cylinders for operating the nippers thereof. Referring to Figures 15 and 16 it will
be seen that the nipper shaft m is provided on its end with a pinion N¹ with which
the segmental gear N meshes. This segmental gear is operated to open the nippers
by means of a spring N3, and to close the nippers by means of a roller ³ carried by the
segmental gear and adapted to follow the face of the stationary cam N. This
segmental gear and its spring N³ are secured to the frame M and are thereby caused
to travel about the stationary cam. It will be observed that the nippers m' are thrown
out of action by a cam, whereas the nippers m³ are thrown into action by a cam.
Qis the fly frame and may be of any ordinary construction. Referring to Fig. 1 it
will be observed that this fly frame has imparted to it a rotary reciprocating move-
ment about its axis by means of a pinion Qoperated by a segmental gear Qupon
a bell crank lever Q3. This bell crank is formed with adjustable arms connected by
an adjusting link for the purpose of regulating the position of the fly frame. This
bell crank has a roller which works upon the cam Q which has the extended
part Q and the depressed part Q. The said bell crank being pressed toward said
cam by means of a suitable spring 72. This cam Q is secured to the shaft B³ of the
impression cylinder B and makes one revolution to each revolution of the impression

page_text: cylinder. The object of the depressed portion of the cam is to allow the fly frame
to drop into the position indicated in dotted lines Fig. 21 so that as the assembling
frame M revolves around the points of the fly frame pass through the notches m³ in
the radially moving bar, and hence the leading edge of the assembled sheets are
brought above the fly frame and may be delivered thereto, as at this instant the
nippers will have released their hold upon the assembled sheets and said sheets in
running down upon the fly frame will pass under the rubber rollers 0 upon a shaft o².
Upon the end of this shaft is a pinion which meshes with the gears 05 of the
frame M. The cam portion Q of the cam Q then operates the bell crank lever to
cause the fly frame to deliver the sheets upon the receiving or folding table R.
We will now return to the pasting devices for securing the sheets together by
means of a line of paste down their middle margin. Referring to Figures 15 to 20
N is the air tight paste fountain adjustably secured to the frame M (which revolves
in unison with frame M) and is made radially adjustable by means of slots 02 and
screws whereby it may be adjusted with reference to the leading edge of the sheet
and thereby insure the deposit of paste in the proper position in the middle margin
with book sheets of different sizes.
The paste fountain is located upon one side of the hollow shaft O and is counter-
balanced by a weight N to prevent the excessive action of centrifugal force. The
paste fountain may be charged while the machine is running by forcing the paste
through the hollow axle O and the branch pipe o which connects the hollow axle with
'the paste fountain and when the fountain is full such condition will be indicated by
the oozing of paste from under the detecting and air vent spring valve o. Ne is the
paste feeding roller and revolves with an intermittent movement back of a narrow
slit n extending the full length of the paste fountain and formed by the edges of the
adjustable scraping plates N which regulate the amount of paste admitted to the slit.
The paste roller N is operated by the eccentric and ratchet mechanism shown in
Figures 15 to 20 from which it will be seen that the said roller is provided on its end
with a ratchet wheel n which is intermittently rotated by a pawl n operated by a
lever No pivoted to the axis of the ratchet wheel and reciprocated by means of the
eccentric strap 0+ and stationary eccentric 03 arranged about the axis of the
frame M. From this it will be seen that as the paste fountain is carried about
the stationary eccentric the ratchet wheel will be intermittently rotated and cause a
corresponding motion to the paste feed and roller N°. There would be enough play
in the adjusting slot of to allow a slight adjustment radially to or from the axis O of
the paste fountain. The sheets on the frame M when receiving paste are supported
by the spring bands M' and said spring bands may be adjusted by moving arms M³ so
as to spring their curvature as indicated in dotted lines Fig. 15 and thereby increase
or diminish their adjustment toward the paste fountain. The frame M is formed with
the spring bands M separated from each other by space so that when the sheets are
being delivered to the fly frame the arms of said fly frame may enter between the
said spring bands so as to be under the sheets supported thereon. From the above
construction it will be observed that as each successive sheet is assembled upon
the assembling frame M the paste fountain deposits a line of paste centrally through
the middle margins of the sheet so collected whereby the said sheets are secured to
each other; and upon the said sheets being transferred to the folding table they are
caused to be laid upon a cover which has been placed downward, and the last deposit
of paste upon the printed sheets will come next to the cover and secure it to the
book.
R is the receiving table of the folding device and is provided with a transverse
slot beneath which are the pressure rollers R¹ around which endless bands travel.
S is the folding knife secured to a rocking lever S and is adapted to fold the assembled
and pasted sheets and back on their middle margins, and such folded sheets and back
are fed between the rollers R and their bands, and are deposited upon the packing
table U. They are then forced back by a reciprocating slide W to the rear of two
spring pawls t, and between said pawls and a retaining frame U¹ which is constantly
drawn toward the said pawls by a chain u and weight u¹. As the books accumulate

page_text: at V the frame U¹ moves back but at the same time holds them in a packed condition.
The folding knife S and its arm is operated by a levers and link which are acted
upon by a cam T secured to the axle B³ of the impression cylinder B. The slide W
is also operated from the same levers by a link w¹, and said levers is caused to follow
the face of the cam by means of a spring device s. X is a spur wheel connecting
the assembling cylinder gears 0 and O with the folding rollers R whereby they
receive motion. The assembling cylinders receive their motion from the impression
cylinder B and have the same surface speed therewith.
I would remark that I do not limit myself to the details of construction involved in
this machine as such details may be greatly modified without in any wise changing
the principal of the invention and it would be readily understood that almost any
form of a folding and packing device might be used with a machine of this class.
The practical operation of this machine has developed the fact that the speed may be
very great without the least injury to the cleaness of the impression or the register of
the sheets. The work printed upon this machine in view of the improvements herein
set out is equal to that of the best printing presses with flat reciprocating beds, and
the assembling and binding is so perfect that trimming is not absolutely necessary.
