Improvements in Stapling and Delivery Mechanisms for Printing
Machines.
I, HENRY EDWARD NEWTON, of the Office for Patents, 6, Bream's Buildings,
Chancery Lane, in the County of London, Patent Agent, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The principal object of this invention is to provide printing machines of that
class which produce the component sheets or leaves of a book-like package, con-
sisting of two or more associated sheets, with a delivery mechanism having means
for uniting webs or sheets by one or more staples, set in or on or near the ultimate
binding line thereof, the plies or leaves being securely bound together, so as to
admit being turned one upon the other without separation at their line of union,
and it relates to the inventions covered by the Patent granted to me, No. 3394
of 1893.
The invention comprises mechanism which forms a staple of wire, presents it
to the setting point, and inserts it into the material to be stapled, and clinches the
staple after it has been set; or the staple may be formed by other mechanism, the
mechanism of the present invention being used only to present the formed staple
to the setting point and insert and clinch the same.
The material to be stapled consists of a web or sheets of fabric, preferably paper,
which have passed through a printing machine, and are presented to the stapling
mechanism for the reception of the staple, whereby its several plies or leaves are
bound together.
The staples are preferably formed upon and presented to the material to be
stapled by rotating carriers, and the clinching device is also preferably carried
by a rotating carrier, although the present invention is not confined to this means
of supporting the stapling mechanism.
In the drawings annexed:-
Figure 1 is an end elevation, partly in section, of the rotary cylinders or carriers
or supports for the stapling mechanisms, together with feeding rollers whereby
material to be stapled may be delivered to the stapling mechanisms. This view
is taken on the section line 1 of Fig. 3, but shows the staple as completely formed
and delivered within the staple holder, in advance of the staple-inserting tool or
driver.
Figure exhibits a similar view of the same parts, but in different positions,
the staple, in this instance, having been inserted into the material, and its legs
having been clinched down thereon.
Figure 3 exhibits a longitudinal sectional elevation of the cylinder or support
that carries the wire-supplying, staple-forming, holding or presenting and insert-

page_text: ing tools, the view being taken on the section line 3 of Figure 1, and some ob-
structive parts removed, to more clearly expose others.
Figure 4 exhibits a front end elevation of the same cylinder or support, as seen

ing the wire-supplying, staple-forming, holding, and inserting tools, the parts
being in the positions shown in Figure 2, but the section is taken on the line 7 of
Fig. 3, to more particularly illustrate the wire feed.
Figure 8 exhibits an inside elevation of the stapling mechanisms, showing more
particularly the wire feeding devices, as seen looking in the direction of the arrow 8
in Figure 7.
Figure 9 exhibits a rear elevation, with some parts broken away, of the rotative
staple-forming anvil and the staple leg-bending arms, or, as seen looking in the
direction of the arrow 9, in Figures 1 and 11, when the staple is in course of
formation.

from the machine, and partly broken away, to exhibit its interior construction.
Figure 13 is a longitudinal sectional elevation of the staple holder or presenting
tool, taken on the section line 13 of Figure 10.
Figures 14 and 15 are views similar to those of Figures 10 and 13 respectively,
but exhibit a modified construction of the staple-presenting tool.
Figures 16 to 27 illustrate a machine embodying a modification of this invention.
Figures 28 to 41 illustrate a further modification.
Figures 42 to 55 illustrate a further modification.
Figures 56 to 66 illustrate a further modification.
Figure 67 to 75 illustrate a further modification.
Figures 76 to 83 illustrate a further modification.
Referring to Figures 1 to 15, it may first be stated, in order to readily under-
stand this invention, that the staple holder or presenting tool 10, which delivers
the staple to the material M, in which it is to be set, and the clinching die 11,
which bends down or clinches the staple legs upon said material, are each carried
in a support that is rotative, the said supports, as illustrated, being cylinders A, B,
but the office of these cylinders, in so far as each tool they carry is concerned, being
merely to support such tool in such a manner that it may. move or travel to and
from the staple setting point for co-operative action with reference to said material.
All unnecessary parts of such cylinders might be removed, or any other suitable
support be adopted, but, it is sometimes desirable to have such supports in the
form of cylinders, as will hereinafter appear, and hence they are so shewn.
In Figure 1, the travelling staple-holding tool 10, and the travelling clinching
die 11 are shown as moving rotatively onward toward the setting point, travelling
in the same direction in which the material M is moving; and thus approaching
the same from opposite sides thereof, which material illustrated as being fed on-
ward between and past these tools, by means of feeding rollers 40, 41. In Figure 2,
the supports therefor have so far moved as to have carried the staple holder 10, and
the clinching die 11, into such complete. co-operative relation at the stapling
point, and in co-action with the staple-inserting tool or driver 12, as to have
accomplished the operations of presenting the staple to the material, inserting it
therein, and clinching its legs. thereon, so that the staple crown bears
upon one side of the material, and its legs upon the other side of

page_text: the material, the plies of which material are thus embraced or bound
together. The plies of material thus fed onward, and united together by
staples, may be two or any other number, the feeding roller 40 having its journals
carried by bearers 42, that are spring-seated in holders 43, thus being arranged
to accommodate any thickness of the material, which may vary considerably
in thickness.
The feeding rollers 40, 41, may receive the material from any source of supply,
and it may be in web form or in sheets. The webs or sheets will preferably be led
through these rollers 40, 41, or directly between the cylinders or supports A, B,
from the machine producing them, as, for instance, a printing machine or machines,
and either before or after being stapled together, may, if requisite, be divided
transversely, or both longitudinally and transversely, into sheets of any desired
size. If fed to the machine in sheet form, then the sheets may be delivered
directly to the stapling mechanisms, or between the cylinders or supports A, B,
which carry such mechanisms, or the sheets may first pass between the said
rollers 40, 41.
There will be one or more stapling mechanisms according to the number of
staples it is desired that the binding line shall contain. Herein (see Figure 3)
two is the illustrative number selected, and they are aligned parallel with the
shafts of the cylinders or supports A, B. The plicated material M will thus be
fastened together by a line of staples set in the material transversely, or at right
angles to its plane of onward travel past the stapling mechanisms.
With this preliminary description, as indicative of the general operation, the
construction and operation of the stapling mechanisms will now be described in
detail, and, as the two sets are.duplicates, it will be understood that a description
of one applies equally to both.
As herein embodied, the supports illustratively chosen for the stapling mechan-
isms are cylinders A, B, which are respectively mounted upon shafts 50, 60, that
turn in journals supported by suitable framing, concerted rotation of said cylinders
being accomplished by intermeshing wheels on their shafts, to which motion is
imparted in the usual manner, but where rollers 40, 41, are used as the feeding
device for the material M, they will also be geared, so as to run in unison with
said cylinders A, B. This gearing is not shown, as it is common, but it may be
here remarked that if this stapling mechanism is made part of the delivery
apparatus of a machine producing the sheets or webs of material, then said gearing
will be properly connected with said machine so as to cause the two to run in
unison.
Except in Figures 14 and 15, the staple holder or presenting tool, 10, is sheath-
like in its construction (see Figure 12), that is, it is provided with a longitudinal
guide-way of dimensions suiting it to receive the formed staple, and admit of the
same being moved longitudinally through, and to be discharged from it, but, in-
stead of being a sheath with continuous walls, its central portion might be cut
away, and thus constitute it of two arms set a suitable distance apart, and cach
having a guiding channel, which channels 16, 17, would face each other, as in
Figure 15.
This holder 10, is preferably arranged to slide longitudinally in a stationary
way formed in an inwardly-projecting bracket 51 (see Figure 7), that is fastened by
screws to the shell of the cylinder A, and that part of said holder facing the rotat-
ing forming anvil is cut away centrally, to form a midway recess 2 that provides
for the entrance of the end of said anvil, as it sweeps into the staple-holder, carry-
ing with it the formed staple (see Figures 1, 12, 13, 14, and 15) which recess for
the anvil and staple is provided, in the sheath-form of Figure 12, by cutting away
the central body of the lower member of the said holder, and in the modification,
Figures 14 and 15, is provided by the width-wise space between the two arms
having the channels 16, 17. Openings a, e, are cut through the holder, so as to
intercept its guiding channels 16, 17, into which openings a, e, narrow portions of
the plates 7, 9, containing the channels 14, 15, project, as shown in Figures 9, 10,

page_text: and 15, to form a substantial continuity between the channels 14, 15 and the chan-
nels 16, 17.
To advance the staple in this holder for presentation to the material, and to
cause the staple to be inserted into the material, and its legs to be clinched thereon,
the setting tool or driver 12 is arranged to reciprocate in said holder. The driver
is a plate-like tool or device that is guided by its edges sliding in the grooves or
channels 16, 17, of the holder 10, and its movements are imparted to it by means
of a lever 31, whose free end is slotted to admit of the traversing movement of the
lever over the pin that connects the two, said lever being fast to a rock shaft 32
that is journalled in bracket arms 52, which project from and are fast upon the
shaft 50, and said shaft 32 is suitably rocked to move the driver by means of a
rock arm 33, the stud 45 of which runs in the slot of a cam 34, that is made fast by
means of a sleeve embracing the shaft, and having a flange by which it is bolted to
the framework (see Figure 3).
The holder 10, when constructed to slide, is maintained in its foremost or pro-
jected position by means of a spring 13 fastened so that it bears against a lug 3,
that is carried by the holder, and which lug also operates to limit the range of
the outward movement of the holder, and thus determine the extent to which the
said holder protrudes beyond the cylinder A or other support, or beyond the plane
of travel of the material to be stapled.
While other means for supplying the holder 10 with staples, which will cause
them to be passed through a midway passage in the body of the holder, and he
deposited in the guiding channels thereof, in advance of the driver 12, with their
legs pointing outward, may be adopted, that herein shown is preferred as one of
advantageous construction, and especially so, because it is not only rotative in its
operation, and therefore capable of high speed in delivering a staple to the holder
or presenting tool, but for the reason that it additionally forms the staple it delivers
by a rotative action.
This rotative staple-forming mechanism consist of stationary staple-bending
arms 4, 6, and a rotatively-moving forming anvil 5, which sweeps between said
arms. The bending arms 4, 6, as shewn herein, are parts of circular plates 7, 9,
that are held in place by flanges through which they are bolted to the shell there-
of, so as to project into the cylinder or support A, and said bending arms are
formed by piercing said plates with wire channels 8, which are enlarged, as in
Figure 9, to permit the necessary movement of the wire ends, as they are being
bent into staple legs.
The rotative forming anvil, 5, is an arm adapted to sweep past said bending
arms 4, 6, and to move between the inner walls of the plates 7, 9, being mounted
adjustably upon a shaft 20 that, is journalled in brackets 53, 54 (see Figure 3),
fast to the inside of the cylinder, and which shaft passes through said plates 7, 9.
This shaft is suitably rotated by means of a toothed wheel 61, fast upon one end of
it, which, through an intermediate 62, is driven from a toothed wheel 63, that is
carried by a sleeve 64 surrounding the shaft 50 and fastened by its flange to the
fixed framework (see Figures 3 to 6).
These plates 7, 9, have cut into their inner faces, staple leg-guiding ways or
channels 14, 15, that are intercepted by the wire passage 8, which guideways or
channels are eccentric with the shaft 20, or axis of motion of the forming anvil 5,
and gradually extend outwardly from the wire-receiving point or passage 8, to the
staple-discharging point; or where they direct the staple midway into the staple
holder or presenting tool 10, the staple passing through the widthwise recess in
the said holder, which recess connects said channels 17, 16. The plates 7, 9, the
guiding ways or channels 14, 15, therein, and the axis of the anvil 5, are so related
to the plane in which said holder is positioned, that this may be accomplished, and
the end of the anvil not only sweep into the holder 10, to deposit the staple therein,
but swing free from the staple it has formed, and delivered into the holder, thus
moving onward to repeat its functions, as will more clearly appear in the setting
forth of the operation of the mechanisms,

page_text: The propelling operation of the anvil 5 not only operates to form the staple legs
substantially at right angles to the crown of the staple, but co-operating with the
channels 14, 15, maintains this relation of them, while operating in connection
with said channels, to carry the staple to the delivery point, and elevate the same
until its discharge into the channels or guideways 16, 17, of the holder 10 is
accomplished.
In order to ensure the proper position of the staple in the holder 10, so that each
staple will be securely lodged therein, and accurately guided therefrom in the
setting operation, advantage is taken of the resilient action of the wire from which
the staples are made, so that the tendency of the staple legs to move apart may
be utilised in securing the proper position of the staple in the holder with respect
to its ejecting guideway. Thus, as is shown in Figures 12, 13, and 15, the guid-
ing channels 16, 17, in the holder 10, are enlarged laterally, at the receiving point,
for the newly-formed staple, whereby as the staple is carried into said channels 16
17 by the propelling action of the anvil 5, and its legs pass out of the channels 14, 15,
said legs may expand into the enlarged portions of the channels 16, 17, as shown in
said figures, said enlarged portions of those channels thus operating as shelves to
support the formed staple by its expanded legs in the plane of movement of the
setting tool or driver 12, and preventing the staple from moving downward. These
channels 16, 17, in advance of the receiving point for the formed staple which
is about mid-way of the holder, are gradually contracted to dimensions which are
equal to the width-wise extent of the staple, when its legs stand at approximately
right angles to its crown.
By this construction, said guideways or channels 16, 17, will operate as the
driver 12 advances, as guideways preventing the legs deviating from a true right
line onward course in the setting plane, or that of the movement of the said driver,
and at the same time act to gradually compress the staple legs toward each other,
so as to attain the right angular position referred to, which will be accomplished
as soon as the staple has passed out of, the enlarged parts of said channels, and
reached or passed into the said channels in the forward part of the holder, said
legs thus passing around the recess and openings a, e, the result being that, the
staple is in absolute control of rigid holding parts from its formation to its setting.
The cylinder or support A also carries within it the wire-supplying and feeding
devices, the shell of said carrier being provided with a removable section 66 to
admit of the introduction of the spools, and also of adjustment of the parts and
repairs thereto. Long lengths of suitable wire are wound upon spools S, that turn
on a shaft 21, whose bearings are in brackets fixed to the cylinder A. The wire
therefrom is led past a curved guiding plate 35, thence between frictional feeding
rollers 22, 23, thence through a guiding eye-plate or block 24 (see Figure 11),
and is finally entered into the wire passage 8. The upper one 22, of the frictional
wire feeding rollers 22, 23, is on a stud suitably supported, and is driven by means
of a bevel wheel 36, on said stud, which meshes with a similar bevel wheel 37
on the shaft 20.
The wire cutting device consists of a suitably shaped arm 1 (see Figure 11),
that is fast on the shaft 20, and it is provided with a cutting edge that sweeps
between the plate 7 and the guiding block 24, and in shearing relation to the
outer surface of the said plate 7. It is shown (see Figures 1 and 2) as moving
concertedly with the anvil 5, and operating to sever the wire slightly in advance
of the impingement of the anvil thereon, but this condition may be changed to
suit the speed of operation, the size of the wire, or any other conditions which
may affect its operation.
The means for clinching the staple legs as here shown, consists of a block or die 11,
that is fastened to the cylinder or support B, so as to move rotatively therewith.
In its face, there is formed a groove of the length of the staple, the ends of which
are tapered or rounded inwardly, as may be it its sides, so as to progressively bend the
staple legs towards each other, and centre or align them, as they are pressed into
it, and said groove is shallow enough to cause said legs, as they are bent, to

page_text: approach, and finally lie flat upon that side of the material opposite to the side
from which they were entered into or passed through it.
The machine being set in motion, the operations will be as follows: —
The wire is fed forward into the wire passage 8, and when a suitable length ex-
tends therein, the rotative cutter 1 and the rotative anvil 5 act in their rotative
circuit, the cutter to sever the wire length, and the anvil to intercept its body or
crown portion, as in Figure 9, and carry the same onward before it. As the anvil
begins to press the wire length onward, it first acts to draw the projecting ends
of the wire-length out of the wire passages 8, then forces them over the bending
arms 4, 6, and then draws them into the channels or guideways 14, 15 in the
plates 7, 9, thus converting said ends into legs, and completing a staple. The
crown of this staple rests against the forward face of the anvil, while its legs,
which lie against the sides of the anvil, are confined in the channels 14, 15, (see
Figure 10), and hence, as the rotative circuit of the anvil is continued, the staple
legs, controlled by said eccentric guide-ways or channels, cause the staple to be
progressively moved outward, as it travels onward, the crown of the staple mov-
ing radially, and passing over the face of the anvil. When the entrance recess or
way 2 into the staple holder or presenting tool is reached, the eccentric guideways
or channels in the plates 7, 9, acting as an elevator, will raise and guide the staple
into said holder or presenting tool, and as the staple is then advanced into the
channels 16, 17 of the holder, the crown of the staple is moved off from the anvil 5,
the staple being thus deposited in the holder or presenting tool, with its crown
laying in front of the driver 12. The staple legs, no longer confined by the chan-
nels 14, 15, but having been drawn out of them, will expand by their resiliency,
and lightly press against the outer wall of the enlarged channels 16, 17 of the
holder or presenting tool, said legs extending forward or in the direction of the
setting movement. As the anvil thus freed from the staple it has formed, and
transported into the holder 10, moves onward rotatively to repeat its operation,
that part of the cylinder or support A from which the staple holder or presenting
tcol protrudes, will be approaching the staple-setting point, as in Figure 2, and the
cam 34 will cause the inserting tool or driver 12 to move forward, carrying the staple
before it, so that it may finally stand supported in the mouth or end of the
holder or presenting tool, during which forward or longitudinal movement of the
staple in the holder or presenting tool 10, its legs, pressed through the contracted
portions of the channels 16, 17, have been gradually bent into right-angular
relation to the staple-crown, ready to be set. When the cylinder or support A
causes the presenting tool to press into contact with the material M that is to be
stapled, and against the companion cylinder or support B or its clinch-
ing die, the staple legs will pierce the material and enter the clinching
die, and thus the holder or presenting tool will be progressively pressed rearward
against the resistance of its spring 13, while the driver 12 will remain stationary,
thereby causing the staple legs to be bent or clinched upon the material M.
When the staple has been completely set by having its crown pressed against one
surface of the material M, while its legs are clinched down upon the opposite sur-
face, as in Figure 2, the holder or presenting tool will continuing to move onward
in its rotary circuit, be again protruded, the driver 12 will be retracted, the wire
will be fed into the passages 8, the forming anvil, will rotate, and the operations
described will be repeated.
The clinching device 11 has been described as travelling rotatively with its
support, as the cylinder B; it is, however, practical, and sometimes advantageous,
to have the clinching die remain stationary, in which case it may be supported in
the requisite position to co-act with the other mechanisms, in performing its
function of clinching the staple legs during the operation of setting the staple.
In such operation of it, there should be a clearance in a downward direction for
the clinched staple legs, in order that, when the staple legs are pressed on to the
material, they may be carried onward with the same, without obstructing such
movement or injuring the material.

page_text: The staple-bound material may be conveyed to any suitable cutting mechanism
for severing it into sheets, but the same may be arranged for co-action with the
other mechanisms, if that arrangement is preferred. When arranged to operate
in direct connection with the other mechanisms, the cutting devices may be inde-.
pendent of the cylinders or supports A, B, and may have combined with them
means for folding the staple-bound sheets, in, on, or near, their stapled line of
union, or the folding mechanism, whether it be of the rotative or reciprocating
type, may be arranged to operate before, after, or during the cutting operation.
It has been stated that it is sometimes desirable to have the supports for the
stapling mechanisms in the form of cylinders, thus, if the said supports are also to
act as carriers for any part of the material that is to be stapled, as would be the case!
if the feeding rollers 40, 41, were omitted, and the material fed directly to or
between the said supports, they would, in cylinder form, impinge upon, and feed
the material forward, or otherwise cause the material resting thereon to be carried:
onward. When these supports are cylinders, they may not only carry cutting.
mechanisms for severing the material into sheet lengths, but support folding
devices for doubling or folding the sheets upon their stapled line of union.
Herein, as illustrative of this, the cylinder A is provided with a cutting blade 44,
that cooperates with a suitable cutting bed or slot provided in the cylinder B, and
the latter is provided with a rotative folding blade 45, 46, that is adapted to co-f
operate with a pair of folding rollers in doubling the sheets transversely. When
the material is thus to be severed into sheets and folded, the cylinder B will
have sheet carrying grippers or equivalent front-end engaging devices to carry the
sheets onward,
It is to be observed that herein the forming anvil bears upon the entire crown
forming portion of the wire length, not only during the forming operation, but
while carrying the formed staple onward for delivery. This is of great importance
in mechanism having this mode of operation, because it prevents the staple crown
from kinking or bending, from which might result such a projection downward as
would prevent the clearance of the forming tool 5 in its rotary sweep through the
holder 10, after having delivered the formed staple therein.
The staple-forming anvil 5 is shewn to be adjustable on its carrying shaft by
means of a holding screw 48. Of course, any other means securing this adjust-
ment may be adopted, the object being to fix the relative movement of the anvil
with respect to the setting movement of the driver 12.
With respect to the holder or presenting tool 10, which has been described as
being sheath-like, as shewn in Figure 12, and, in a modified form, as consisting of
two opposed arms, as illustrated in Figures 14 and 15, it is to be observed that
Figure 14, being taken on the section line 14 of Figure 15, shows a facial view
of the arm containing the channel 17; and it is to be noted, that in the sheath
form, the tool has a reciprocating motion, and in the modified form shewn in
Figures 14 and 15, it is a stationary device. Of course, there might be a bridge bar
leading from one arm to the other at their forward ends, said bridge bar being
provided with a lug to operate as does the lug 3, and thus convert these separate
stationary arms into a moving structure, suitable guides being provided for
them to move in.
Where the holder or presenting tool reciprocates, it is obvious that the openings
a, e, provided for the protusion therein of portions of the plates 7, 9, so that the
channels 14, 15, therein may intercept and communicate with the channels 16, 17,
in the holder, must be elongated, as shewn in the drawings, to admit of the recip-
rocation without interference with said plates.
As herein illustrated, the enlarged parts of the channels 16, 17, are connected
rearwardly as well as forwardly with the enlarged portions of said channels by
angular portions. Of course, this is not essential in the rearward direction, but
is preferable, since it accommodates the shape taken by the staple, and thus said.
staple, in its entire transit through the holder, has its legs continuously supported..

Figure 27 is a detail of the staple-presenting tool.
Figures 22 to 27 are on an enlarged scale.
The paper to be stapled is led to the stapling mechanism from any mechanism
suitable to prepare the paper which is to be stapled.
Referring to Figures 16 to 27, 110, 120 represent the delivery rolls of any such
mechanism. A suitable mechanism for the purpose (as is also the case with regard
to the improvements shown in Figures 1 to 15, and with regard to the improve-
ments hereinafter shown in this Specification) is a longitudinal folder of the type
set forth in British l'atent granted to William Conquest, dated December 5th 1885,
No. 14,948. The paper may, however, be presented to the stapling mechanism in
the form of sheets, if desired, though the web form is considered preferable; and
any other form of mechanism for preparing and presenting the sheets may, if
desired, be employed.
The paper to be folded passes between two carriers A and B, one of which carries
mechanisin for forming and presenting staples, and the other carries clinching dies
co-operating therewith; but the clinching dies may be stationary, if desired.
The carrier A is preferably provided with a number of stapling mechanisms
spaced along its length, in order to form in the paper a transverse seam made up of
a number of staples. These mechanisms are similar, and a description of one of
them will, therefore, suffice for all, and it will, therefore, be understood that the
description which will be given applies equally to all these mechanisms, although
parts are for convenience referred to in the singular number instead of in the
plural.
From the wire spools 51 mounted in the carrier, the wire passes to a fixed
guide 52, and thence over a roller guide 53, thence between the feed discs 54, 55,
which gear together, and one of which, 55, carries on its shaft a bevil gear 56,
which meshes with a second bevil gear 57 upon the shaft 58 of the stapling
mechanism, which shaft has, on its outer end, beyond the cylinder, a gear
wheel 59, which engages with a fixed gear 60, and is given a rotary motion
thereby, as the cylinder revolves.
The wire passes from the feed discs to the fixed guide 61 (see Figure 20),
through which it passes to the anvil. The latter consists of arms 62 and 63 fixed
to the cylinder, and provided with shoulders 64 and 641, which serve as an anvil.
The staple-bender is formed of two bending dies 65, 66, which are rotary, and
mounted on shaft 58, and are placed just outside of the arms 62, 63, and are pro-
vided with shoulders 67, 671, which co-act with the shoulders 64, 641, to form a
staple, as shown in Figure 23.

page_text: After the staple is formed, the legs of the staple will lie in the spaces provided for
them between the arms 62, 63, and the shoulders 67, 67¹. In order to provide for
lifting the formed staple over the anvil in order that it may be carried to the place
of setting, the bending dies are provided with cam-like surfaces 68, 69, which, as
the bending dies revolve, serve to elevate the staple to the position shown in
Figure 16. This elevation may, if desired, be secured by the action alone of the
cam-like surfaces 68, 69; but in order to ensure the proper elevation of the crown
of the staple, it is desirable that the anvil should be made in two parts, as shown,
with a cam-like surface 70 between them, which shall serve to positively lift the
crown of the staple.
The means by which the staple is presented to the material to be stapled, con-
sists, in the construction herein shown, of the sheath or guide or presenting tool 1,
supported by the bracket 72, and normally stationary with reference to the carrier,
and projecting outward through the shell of the carrier, as shewn in Figures 25
and 26, and held in its outward position by the pressure of a spring 73 against
leg 74. The presenting tool is cut away below, so as to permit the staple to be
introduced into it, and also to permit the clearance of the rotating bending dies.
The staple, when elevated by the cam-like surfaces on the bending dies, is forced
forward by the driver 75 to the front end of the presenting tool, assuming the
position shown in Figure 17. The driver is moved at proper times to carry the
staple forward by a cross head 76 moving in a slotted arm 77 attached at one end
to the cylinder shell and at the outer end to a collar 78 mounted upon the cylinder
shaft. This cylinder shaft carries, at the cylinder ends, collars 79, in which is
journalled the shaft 80, which shaft has fixed upon it the arms 81 and 82. The
arm 81 engages, by means of a slot, the cross head 76, and gives the proper move-
ments to the driver, as it is moved by a cam roll 83 on arm 82 engaging with the
path cam 84, in the cam plate 85 fixed to the shaft 58.
As stated above, when the staple is about to be driven, the parts assume the
position shown in Figure 17; and as the staple is carried to the position in which
the carriers A and B are in close proximity to each other, the staple is forced
through the material by the proximation of the cylinders, it being held from
retracting by the driver; at the same time, the presenting tool 71 is forced back
against the spring 73 by the carrier B, until, at the moment of clinching the staple,
its outer end is flush with the carrier A. The legs of the staple are clinched by
the clinching die 86.

Figure 39 is a plan view of the same, detached from the cylinder.
Figure 40 shows two perspective views of one of the guide blocks, and
Figure 41 shows the staple leg clinching anvil block, and the adjustable plate
upon which it is mounted.
The stapling mechanisms on the right and left hand ends of the carrier are sub-
stantially alike, and the parts of each are symmetrically placed with reference to
each other. A description of one will, therefore, suffice for both.
Referring to Figures 28 to 41 generally, the web or webs of paper M are led to
the stapling mechanism from any appropriate printing and folding or associating
mechanism between the carriers A, B, which support the stapling mechanism, and
which may also carry cutting and folding mechanisms, although, of
course, if preferred, the cutting and folding operations may be per-
formed by other means. The staple-forming mechanism. consists of
two arms 101, 102, which are carried by the plates 103 fixed to
the cylinder shell, these armis being provided with shoulders or abutments, 104,
which together form an anvil against which the wire is bent to form the staple.
The wire is fed from, spools 105, 105', mounted upon the end of the cylinder between
guide rollers and feeding discs 106, 107, and into guiding slot 108, which latter
conducts the wire to a position where it lies against the anvil shoulders, 104. The
feeding discs 106, 107, are, in the construction shown, cut away so as to make the
feed intermittent, but, if desired, the feeding discs may be made continuous, the
parts being so arranged, in that case, as to give the wire clearance for movement
as it is fed forward.
The staples are bent by a bender consisting of two forming discs 109, 110, mounted
upon a shaft 111 journalled in the cylinder, these discs 109, 110, being placed
one on either side of the arms 101, 102, and having shoulders or dies 112, 113,
which co-operate with the anvil shoulders 104 to bend the staple, as best shown in
Figure 34. Shoulder 112 also serves as a knife to sever the staple-forming length
of wire. Space is left between the arms 101, 102, and the discs 109, 110, for the
reception of the staple legs, when bent.
Mounted on the shaft 111, between the discs 109, 110, and also between the
arms 101, 102, is a third disc 114. The disc 114 may be provided with a cam-
like surface, or a rise, 115, which acts to lift the middle portion of the staple after
it has been bent over the anvil shoulders 104, and into the position shown in
Figure 32. The discs 109, 110, are also provided with similar rises 116, 117, for
the purpose of lifting at the same time the legs of the staple, so that the staple,
as a whole, shall lie tangentially to the circumference of the discs 109, 110. The
disc 114 is also provided, immediately behind the rise 115, with a shoulder 118,
which engages with the central portion of the staple, and carries it forward when
it is lifted above the anvil shoulders, as shown in Figure 32. The staple is
retained in this position by a curved spring or metal strip 119 attached to the
framework of the carrier by a bracket 120. The three discs 109, 110, 114, may
be made separate, and fixed to the shaft, or they may be made in one piece.
At the point where the circumference of the discs 109, 110, comes nearest to the
circumference of the carrier B, are mounted two guide blocks 121, 122, which are
dovetailed into block 123 fixed to the plate 103, and sliding in the said block
radially to the carrier. These guide blocks are placed opposite to each other in
the direction of the length of the cylinder, and with the space between them
equal to the width of the staple, and are provided upon their inner surfaces with
grooves 124, 1241, which are curved outwardly from a direction tangential to the
circumference of the discs 109, 110, to a direction radial thereof as shown in

page_text: Figure 32. These blocks are provided with lugs 126, against which bear
springs 127, pressing them outward, and their outward movement is limited by
the contact of lugs 128 with the surface 129 of recesses in blocks 123.
In the normal position of the guide blocks 121, 122, when the same are pressed
outward by the springs 127, the guiding slots 124, 124¹, register with the space
between the strip or spring 119 and the discs 109, and 110, so that as the shoulder 118
revolves, it will push the staple into the slots, as shown in Figure 32. As the guide
blocks come to the staple-setting point, they are pushed in by the surface of the
carrier B, against the pressure of springs 127, to the position shown in Figure 29,
the discs 109, 110, being provided with the recesses 131 to permit this inward
movement. The disc 114 is provided, just back of the shoulder 118, with a
gradually elevated portion 132, which serves to lift the staple by bearing against
its crown after the staple has passed into the guiding slots 124, 124', as shown
in Figure 29, the rear portion of which acts as a setting bed for the staple. The
rear part of this projection 132 is made with side flanges 133, giving the bearing
surface a width equal to the total width of the staple, so that the whole of the
central portion of the staple will be supported while it is being set. The plates 103
are recessed, as shown in Figures 38, 39, to permit these flanges to pass, as they
rotate.
The staple leg clinching anvil block 134 (Figure 41) is mounted upon a plate 135,
which is held to the carrier by set screws 136, 137, and is adjusted by loosening
these screws, and turning the excentric screw bolt 138.

modification of this invention.

point of view being indicated by the arrow 52 in Figure 51.

The stapling mechanisms on the right and left hand ends of the carrier are
substantially alike, and the parts of each are symmetrically placed with reference
to each other. A description of one will, therefore, suffice for both.
Referring to said Figures 42 to 55, the web or webs of paper M are led to the
stapling mechanism from any appropriate printing and folding or associating
mechanism between the carriers A, B, which support the stapling mechanism, and
which may also carry cutting and folding mechanisms, although, of course, if

page_text: preferred, the cutting and folding operations may be performed by other means.
The staple-forming mechanism consists, in part, of two arms 151; 152 (one of
which is shown in perspective in Figure 49, and the other in side view in
Figure 47), which are carried by the plates 153, fixed to the shell of carrier A,
these arms being provided with shoulders or abutments 154, constituting an anvil
against which the wire is bent to form the staple. The wire is fed. from
spools 155, 1551, mounted upon the end of the carrier, between feeding
discs 156, 157, to guiding slot 158, which latter conducts the wire to a position
in which it lies against the anvil shoulders 154.
The staples are bent by two forming discs 159, 160; mounted upon the shaft. 161,
journalled in the carrier, these discs 159, 160, being placed each on one side of the
arms 151, 152, and having shoulders 162, 163, which co-operate with the anvil
shoulders 154, to bend the staple, as best shown in Figure 46.
Shoulder 162 also
serves as a knife to sever the staple-forming length of wire.
Mounted on the shaft 161 between the discs 159, 160, and also between the
arms 151, 152, is a third disc 164. The disc 164 has a recess 165 in which is
pivotted a lever 190, keyed to a shaft 191 journalled in the discs 159, 160, and
having keyed to the end thereof the arm 192, at the other end of which arm is
placed a bowl 193, running in a path cam 194 fixed to the carrier. This lever 190
is guided by the cam 194 appropriately to move the staple as hereinafter
explained. The discs 159, 160, are provided with cam-like surfaces or rises 166, 167,
for the purpose of lifting the staples over the anvil shoulders 154, so that the
same shall lie tangentially to the circumference of the discs 159, 160, as shown in
Figure 47. After it has been so elevated by these rises, the tip of lever 190 comes
in contact with it, as shown in Figure 47, and pushes it forward, it being confined
in this position by the curved guard 169 attached to the frame-work of the carrier
by bracket 170. The three discs 159, 160, 164, may be made separate and fixed
to the shaft, or they may be made in one piece.
At the point where the circumference of the discs 159 160, comes nearest to the
circumference of the carrier B, is mounted a guide block 171, which lies radially
of the carrier in blocks 173, 1731, fixed to a plate 172, attached to the carrier
shell. This guiding block is provided with interior grooves 174, 174¹, which are
curved outward from a direction tangential to the circumference of the
discs 159, 160, to a direction nearly radial thereof, as shown in Figure 47. This
block is provided with a lug 176, against which bears spring 177, pressing it out-
ward, and its outward movement is limited by the contact of lugs 178, 178¹ with
the upper surface of recess in blocks 173, 173¹.
In the normal position of the guide block 171, when the same is pressed outward
by the spring 177, the guiding slots 174, 1741, register with the space between
the guard 169 and the discs 159, 160, so that as the tip of the lever 190 revolves,
it will push the staple into the slots, as is apparent will be the case from inspection
of Figure 47. As the guide block comes to the staple-setting point, it is pushed
in by the surface of carrier B, against the pressure of spring 177, to the position
shown in Figure 42, the arms 151, 152, being provided with recesses 181, to permit
this inward movement. The action of the cam 194 upon the lever 190 is such,
that the tip of this lever pushes the staple through the guide-ways 164, 164¹, the
lever 190 being provided with flanges 179, 180, which run in these grooves, and in
this manner the lever 190 pushes the staple up to the setting point, as shown in
Figures 42 and 47. The flanges 179, 180, broaden the tip of the lever 190, so that
it extends the whole width of the staple, and gives a full bearing to the staple crown
as it is being set. The guide block 171 is cut away, as shown in Figure 50, to
permit the passage of these flanges, as the lever 190 leaves the guide block in its
continued rotation after the setting of the staple.
The staple-leg clinching anvil block 184 is fixed to the carrier B in any suitable
manner. The bearings 200 of the wire-feeding reels are made adjustable, so
that the friction thereon may be increased or diminished, as desired, as shown
in Figure 55.

page_text: Referring to Figures 56 to 66, which illustrate a machine embodying another
modification of the invention,
Figure 56 illustrates, by an end elevation, and Figure 57, by a side elevation,
so much of a delivery apparatus of a printing machine, as is necessary for an
understanding of the relation of the stapling mechanism thereto.

The means for supplying the plicated material to the stapling mechanism may
be any suitable mechanism, that referred to in connection with other forms of the
invention being illustratively shown, consisting of a longitudinal former F, having
guiding rollers or external turners 250, 260, and nipping or fold-laying
rollers 270, 280, over which many webs, as W, E, B, S, are shown as travelling.
These nipping rollers are geared together to run in unison, one of their pinions, 279,
being shown in Figure 57.
The plicated material M is so delivered to the stapling mechanism as to pass
between the rotating carriers A, B, which support the stapling mechanisms, the
carrier A being supplied with duplicating sets of stapling mechanisms for feeding
wire thereto, cutting the same into staple lengths, forming the said legs into
staples, presenting them in setting position, and inserting them through the run-
ning material, while the carrier B supports a like number of staple-leg clinching
devices, whereby said staple legs protruded through the material are bent or
clinched down thereon.
These carriers might be sufficient only to act as carriers for these stapling
mechanisms, but as it is preferable for compactness of machinery, the room for
which is often limited, said carriers are also made to support cutting mechanisms
for severing the webs into sheet lengths, and with folding devices for folding the
same, and as these carriers are made double also, so as to operate upon two sets
of sheets in one revolution, these carriers are supplied with double sets of stapling
mechanisms, and with double sets of cutting and folding mechanisms, circum-
ferentially considered, and for the reason that the stapling mechanisms are so
arranged to form a binding seam transversely to the run of the material, the
stapling mechanisms are also multiplied in the carriers in a longitudinal direction,
two sets being so arranged as the selected number sufficient for the width of the
material shown as operated upon.
As the stapling mechanisms are all constructed alike, a description of one set
will now be given in detail, it being understood that the description thereof, and
the letters of reference applied thereto, may be read upon any of the other duplicate
sets for an understanding thereof.
The stapling mechanism consists, in a broad sense, first, of a forming die, as 240,
stationary with respect to the rotating carrier A; second, of a reciprocating
former, as 241, whereby a wire length is formed into a staple; third, a rotating
staple transferrer that is provided with a multiplicity of staple-receiving pockets
into which the formed staples are successively delivered, which transferrer trans-

page_text: ports said staples from the forming point to the delivery point; and, fourthly, o
a reciprocating setter or driver 243, whereby said formed staples are inserted or
driven through the running material, when the carrier A has moved the stapling
mechanism to the setting point for the staples (see Figures 63, 64). This forming
die consists of a block pierced longitudinally, with a wire guide slot for the intro-
duction of the wire, and transversely with a recess for the passage of the former 241
said slot being enlarged rearwardly at each end of the die 240, to permit the
canting of the ends of the wire length during their formation into staple legs,
and said recess being made sufficient to provide, at the side of the former, spaces
for accommodating the staple legs in their formation (see Figure 64).
The stapling mechanism and supports for its moving parts are held stationary
with respect to the carrier A by means of brackets 301, 302, secured to the inner
face of the shell of the carrier (see Figure 56). The former, 241, and setter or
driver, 243, are connected together so as to move in unison by means of a
slide 245, from which they project laterally, which slide moves in a way, 246, sup-
ported by the bracket 302, being driven by an arm 251 connected with it, having
à bifurcated end, by which it is guided by the shaft 205, and being provided with
a friction bowl laterally extending into a groove of a cam 303.
The wire from which the staples are to be made is carried by a reel 247 (see
Figure 66), from which reel the wire is led between feeding rolls 230, 231, passing
through a guide and thence to the die 240. The wire is intermittently fed forward
a staple length until its end is arrested by a stop plate 244 by the rotative move-
ment of the rollers 230, 231, accomplished by means of a segment, 232, vibrated
by a cam 233 on shaft 205, which is rotated by means of a wheel 234, which is
driven by meshing with the toothed wheel 235, encircling the main shaft, fast on
a sleeve secured to the side frame, said segment 232 engaging with a pinion 206,
which carries a ratchet wheel 236, with which co-operates a spring-seated pawl 237,
that is fast to the feeding rollers 230, said feeding rollers operating by frictional
contact, when driven by the ratchet to properly advance the wire.
The slide 245 also carries a cutter 209, which, in cooperation with the receiving
end of the die 240, operates by a shearing action to sever the wire, and detach a
staple length thereof, just as, or immediately before, the former 241 contacts with
said wire length in the operation of forming it into a staple. Each staple, as
formed, is, by the continued forward movement of the former 241, thrust into and
delivered in one of the pockets 310 of the transferrer, 242, the transferrer standing
still during this operation.
The transferrer 242 turns on an axis supported by the bracket 301, which is
in such a position that a portion of its periphery protrudes through the shell of the
carrier A, and is intermittently rotated through a step-by-step movement, accom-
plished by means of a ratchet wheel 238 which it carries, through which it is
driven by a pawl 248 hung to a vibrating arm 249, which arm, journalled on the
shaft of the transferrer, is vibrated by an arm 239, that is bifurcated to embrace
a shaft, and provided laterally with a friction bowl that runs in the groove of a
cam 304.
As each step movement is finished, its position is maintained by a spring
pawl 252, whose rounded end presses into a suitably formed recess near one edge
of the periphery of the transferrer. At each step-like movement, the pockets,
one after another, are supplied with-made staples, said staples, as they are inserted
in these pockets, having their crowns pointed toward the place for setting the
same. This inverted position of the staples is gradually reversed as the trans-
ferrer makes its rotation, so that when a pocket loaded with the staples is presented
at the periphery of the carrier A, it has its legs pointed outward.
The rotative movement of this transferrer is so timed that when a loaded pocket
is moved by the carrier A to the point for the insertion of said staple, the said
transferrer will have ceased to rotate, and be stationary with respect to the carrier,
with said pocket aligned with the setter or driver 243, at which time a forward
movement of the setter 243 and former 241 will simultaneously be made, the one

page_text: to thrust a made staple outward through the material, and aid in clinching the
same, and the latter to form a new staple, and load a pocket therewith.
The carrier B is provided with an appropriate number of setting or clinching dies,
and is geared to the carrier A, so that the two carriers run in unison, one of their
connecting gears, 310, being shewn in Figure 57. Each clinching die, in this
case, is at the end of a bar 215, fastened to the shell of the carrier in the proper
position.
From the foregoing, it will be understood that these operations of feeding the
wire, forming the staple, and transferring it to the setting position are constantly
going on within the carrier A at an appropriate speed, while the carrier is con-
stantly rotating at a higher speed, suited to that in which the material to be
stapled is moving, and that when a suitable length of material has passed between
the carriers A, B, one or the other of the staple transferrers will be presented at
the setting point, or where the carriers A, B, run nearest in contact, the trans-
ferrer 242 then being stationary, and one of these pockets presenting a made staple
in position to be set, and that at the appropriate moment to which the mechanisms
are timed; the setting tool or driver 243 will be quickly advanced to make contact
with said staple, drive the same outward, insert it through the passing material,
and cause its legs to enter into the die 203 of the carrier B, and thus be clinched
onto said material, which material, thus stapled, will pass onward for delivery.
Of course, the finished material might pass from the carriers A, B, to any
delivery mechanism, or first to a cutting, and then to a folding mechanism of any
suitable construction, but as it is convenient, as before stated, to combine cutting
and folding mechanisms with the carriers which support the stapling mechanisms,
it will be understood from the state of the art, that the material M, will be
temporarily held on the periphery of the carrier B, and be made to overlap a folding
blade, as 275, and that when said folding blades arrive over a pair of folding rollers,
said folding blade will be projected to double or fold said stapled product into the
nip of said folding rollers, in the manner well known.
Also, that when the proper length of the stapled material has passed, a cutting
blade, as 225, will, cooperating with the female cutter on the carrier B, trans-
versely sever the material, to divide it into sheets.
Referring to Figures 67 to 75, which illustrate a machine embodying another
modification of my invention, Figure 67 represents an end elevation, as seen in
the direction of the arrow 67 of Figure 68, of so much of a delivery apparatus of
a web printing machine as is necessary to illustrate the relation of the stapling
apparatus thereto, an outside cam being removed, and some of the parts being
shown in section.
Figure 68 is an elevation of the same, as seen looking in the direction of the
arrow 68 in Figure 67, one side frame and wire spool being omitted, so as to
illustrate other parts more perspicuously.

adjusted in positions differing from the illustrations in Figures 67 and 68..

page_text: the
The primary part of this delivery apparatus consists of longitudinal folders,
which may be of any construction, such, preferably, as are described in the Con-
quest British Letters Patent above referred to, and here represented by the
lower parts of their internal guides or formers F, their external turners in
form of guide rollers 450, 460, and fold-laying devices in the form of a single
roller, as 469. Two such primary longitudinal folders are shown, and they are
arranged to have their products. conveyed to the stapling mechanisms by means
of delivery rollers 470, 480, one, 470, of which, is spring-seated, the pair thus
becoming drawing rollers for advancing the material. It will be understood that
either one of said longitudinal folders may be separately used; that only one need
be provided; and that the material to be stapled may be delivered to the stapling
apparatus from any other mechanisms. Beneath the said delivery rollers, the
rotative carriers A, B, which support the stapling tools, are mounted to revolve
in suitable bearings, and below said carriers, and in like manner mounted in
bearings, are rotating carriers C¹, D¹, provided with cutting and folding
mechanisms of the general construction and operation shown and described in the
specification of the above-named Patent granted to me, and at one side of the
apparatus an additional or secondary folder is shown. Its structure is the same as
that of the primary longitudinal folders, although only the internal guide or
former G, and external turners 498, 499, are shown.
The shafts 451, 452 of the carriers B, A, are geared together by wheels 453, 454,
of equal size, the wheel 453 being driven through an intermediate 455, from a
wheel 456 on the shaft 457 of the carrier C¹, which wheel, 456, will be driven by
gearing connecting with that of the printing machine, so that the mechanisms
of this delivery apparatus may move concertedly with those of said printing
machine. The shafts the delivery rollers 470, 480, are geared together by
pinions 458, 459, the latter being driven by an intermediate 461, which engages
a wheel 462 on the shaft 452 within the side frame, the wheel 462 also driving,
through companion intermediates 463, 464, mounted on a stud 465 carried by a
bracket, a wheel 466 fast on the shaft 471. The wire-feeding mechanism is
arranged to be adjustable horizontally on this shaft 471 and a slotted bracket 472,
and the wire-feeding rollers thereof are geared together and driven concertedly
by pinions 467, 468, the lower pinion 467 of the pair being splined on said
shaft 471. It should also be preliminarily understood that the material or paper, M,
to be operated upon, is, in passing through the longitudinal folding apparatus,
doubled or folded longitudinally, as it emerges therefrom, and thence it passes
through the rollers 470, 480, and between the carriers A, B. This product, con-
sisting of any number of plies from any source, has, in the construction illustrated,
three plies, 490, 491, 492, from each of the longitudinal folders shown, or six
plies from the two longitudinal folders shown, and is to be bound together by
ineans of staples set longitudinally in it while it is passing between the carriers A, B,
and the stapling mechanisms which they support. This stapled material, in passing
between the carriers C¹, D¹, as indicated in dotted lines in Figure 67, is cut trans-
versely into suitable sheets or lengths, and the same is folded transversely to
reduce its size into proper handling or packaging dimensions, by the mechanisms
supported by said carriers C, D)'. Instead of passing between the carriers C¹, D¹,
the stapled material or paper M may be diverted in its course by means of
rollers 473, 474, whereby it is fed outward, and from which it is led over the
internal guide or former G of a longitudinal folding mechanism, by which it
will be again folded longitudinally, and on the stapled line.
The material to be operated upon is supposed to be composed of many plies,
indicated in the drawings by the webs 490, 491, 492, which, in passing over the
longitudinal folders, will be folded longitudinally one within the other, and two
longitudinally folded packs of these plies are brought together at the rollers 470 480,
the same requiring to be fastened together to retain them in this association, in
which case their doubled edges will be secured by staples passing through all of
the plies near such doubled edge, if the stapling mechanisms are arranged as is

page_text: shown in Figure 69, but it is to be understood that this building line may be the
edges of several webs, formed by slitting said webs as they pass over the said longi-
tudinal folder, or be the product of several longitudinal folders having doubled or
cut edges, or be associated plies from any other web- or sheet-associating mechanism.
The mechanism for performing the stapling operations will now be specifically
described.
It will be observed, from an inspection of the drawings, that the carriers A, B,
are provided with four sets of stapling mechanisms, see Figure 67. This is for
the reason that, since the staples are set longitudinally, or parallel with the run
of the material, they must be inserted therein in close proximity, so as to form a
continuous longitudinal seam (see Figure 68), and while four sets are shown, three
or even two might suffice, or five, or any other number, be used, according to their
nearness to each other desired, as fastening points for the material, and while
only one of these duplicated mechanisms will be specifically described, it is to
be understood that this description applies equally to all, although, for convenience,
the singular number will be used in said description.
The carrier A supports the wire receiving, holding, cutting, staple-forming and
setting mechanism or devices, while the carrier B supports the staple-leg clinching
devices, and as the stapling mechanisms operate to provide the material with
staples as a binding means on a line to constitute à longitudinal seam, said
mechanisms, and the carriers therefor, are preferably made only wide enough
to constitute supports for said mechanisms, but, if desired, said carriers may be
made wide enough to afford support for the passing material throughout a con-
siderable portion of its widthwise dimensions, although this is not requisite. On
the contrary, it is most desirable to have the carriers narrow, and adjustable longi-
tudinally on their carrying shafts, so that said longitudinal binding seam may be
made in a longitudinal line in any position desired relative to the widthwise
dimensions of the passing material, and again, as it is preferable many times to
form said longitudinal binding seam adjacent to the fold or edge nearest the
observer in Figure 67, the operation will now be described generally, without
regard to the adjustability of the stapling mechanisms, which will hereafter be
more fully referred to.
The wire from which the staples are to be formed is drawn from a reel 440,
has its end passed through a guide 441, and entered between the wire-feeding
rollers 442, 443, by which it is regularly fed forward at a suitable speed, to pro-
trude a
length of wire in the path of the stapling mechanisms, in the proper
fraction of the time occupied by one revolution of the carrier A, in this instance,
one fourth. In thus being carried to the stapling mechanisms, it is, in the
construction shown, directed so as to lie in a guiding channel 414, with which the
carrier A is provided in its periphery, and when laid in and guided by this
channel 414, the forward end of said wire will be controlled in position by means
of the laying or pressure wheel 408, which is slightly pressed to this duty by a leaf
spring 418, which constantly presses it lightly downward.
Each set of the stapling mechanisms supported by the carrier A, consists of
arms 411 and 412, supported to slide in suitable guideways formed in the carrier A,
so that said arms may be periodically protruded from, and be moved within, the
periphery of said carrier. These arins are supported in said carrier a distance
apart equal to the length of the crown of each staple, and that portion, 444, of the
channel 414 which intervenes between the guideways for these arms, becomes,
as will presently appear, the setting bed or driver for the staple.
The stock of the arm 411 is secured by a pin 420 to a rock arm 421, fast on a
stud 422, which is mounted so as to revolve freely in the carrier A, which arm 421
is rocked at suitable intervals, to move the arm 411, by means of a rock arm 423,
attached to said stud 422, and appropriately moved by the driving face of a cam
slot 500 in the cam S¹, and the arm 412 is likewise pinned to a rock arm 424
splined to a shaft 425, which latter is vibrated by a rock arm 426, that is suitably
moved by a slot 501 in said cam S³, this cam S¹ being secured in the front of the

page_text: carrier A, as is shown in Figure 68, the said cam being shown in partial section
in Figure 72, in elevation in Figures 68 and 73, and in plan in Figure 69.
Between the said arms 411, 412, a clamping jaw 409 is pivoted, so as to swing
laterally with respect thereto, and press the wire into the said setting bed or
driver 444, and clamp the same therein, said jaw 409 being adjustably secured by
the screw 416 to a bracket 431, through which passes the pivot 406, by which said
jaw 409, and the other parts carried by the bracket 431, are pivoted to swing in the
carrier A. The arms 411, 412, have facial grooves (see Figure 75) in continuation
of the channel 414, to admit of the passage of the wire. The bracket 431 also
carries a cutter 401 (see Figures 73, 75), the cutting edge of which moves in
shearing contact with the outer surface of the arm 411, so as to cooperate therewith,
or with the slight groove therein, in severing the wire.
The swinging or vibrating movements of the bracket 431, and the tools which it
carries, are accomplished by means of a rock arm 432, which rock arm is provided,
at its free end, with a spring 433, which constantly presses it upward, and thus
throws said tools outward, or out of their active position, said
arm also
being provided with a stop 434, which limits such movement. The movement of
the bracket 431, and the tools it carries, through the arm 432 is accomplished,
in the opposite direction, by means of a shoe 435, attached to the arm 432, and
having a curved upper or bearing surface that makes contact with the raised
portion 4361 of the under surface of a curved arm or horn 436 fixedly placed upon
the frame to overhang the carrier A, and along the curved pathway of which the
shoe 435 travels.
After the wire is severed, the free end of the main portion of the wire is held
down in the groove by the pressure of the roller 408, while the rear end of the
severed portion of the wire is held down by the pressure of the spring 490.
The carrier B is provided with setting or clinching dies, 413, corresponding
in number with the stapling mechanisms supported by the carrier A, and each of
these clinching dies has a stem by which it is secured in a stock 428. The
stock 428 has at its inner end, a curved seat, by which it rests upon the hub of the
carrier B, and is provided with a central elongated recess (see Figure 71), through
which passes its holding bolt 438, set fast in the carrier. This stock 428 is pierced
laterally by screw sockets, in which set screws 427, 429, are provided. By this
construction, the stock 428, and with it the setting die 413, may be adjusted
circumferentially and a nice adjustment of the setting die with respect to the
staple-presenting devices is attained. This is an important improvement, for the
reason that the wire used in making the staples may vary in size or hardness,
and thus require fine adjustment, in order that the setting die may properly act in
projecting and bending down the legs of the staple. Of course, the clinching die
may be stationary, as provided according to the patent before mentioned.-
Inasmuch as the wire used in the stapling operation is very small, and has little
resisting strength, it is desirable that it should be supported until it penetrates the
paper. This is done without difficulty in those cases where the staple presented
with both its legs in the same horizontal plane; but in the present cases, where
the two legs are in the same vertical plane, the crown of the staple lying in the
direction of the longitudinal movement of the webs being stapled it is more diffi-
cult, since, in order to accomplish this result, the two legs must have separate and
independent supports, which are withdrawn at different times, to permit the
successive complete entry of each of the two legs of the staple in the material being
stapled.
In the specification of my above mentioned patent, is shown a mechanism for
setting staples in this manner, in which the staple support consists of two swinging
members. These members are moved from the same shaft, but one of them is
attached to the shaft through a spring, and therefore can move to a certain extent
independently of the other member. Thus, as the advanced leg of the staple is
driven, the spring-pressed member of the staple support moves backward under
the push of the carrier which supports the clinching die, and the member sup-

page_text: porting the rear staple leg remains in its supporting position until its leg is
properly inserted.
The present invention supplies an improvement to this mechanism, in that
both members of the staple support are given a positive motion in each direction
independently of each other; which is more satisfactory than movement derived
from the clinching-die carrier.
This arrangement has the further advantage that the parts which bend and sup-
port the staple legs, since they slide instead of swinging, may be caused to move
in directions angular to each other, so as to cause the staple legs to be inclined
toward each other, that is, beyond a position of parallelism, before they pass into
the material being stapled. In this manner, both legs of the staple may be given
a greater initial bending preliminary to insertion into the material being stapled
than is possible in the use of the device of my patent aforesaid, and their final
clinching by the clinching die will be more certain and perfect than it would be,
if the legs were pressed down from a position of parallelism solely by the operation
of the clinching die.
The sliding bending, and supporting arms also have an advantage over the
swinging arms, in that a sliding arm may be given more readily any desired
direction of movement than a swinging arm.
The stapling operation is as follows:-
1
The wire from the reel 440 is constantly fed onward by the feeding rolls 442, 443
at such a speed as to protrude into the channel 414 of the carrier a length of
wire sufficient for the formation of a single staple during the period of time
elapsing between successive stapling operations.
In this case, the feeding rolls 442, 443, are driven at a surface speed sufficient
to furnish the required amount of wire in one fourth of a revolution of the
carrier A, for the reason that said carrier is provided with four sets of stapling
mechanisms in the circumference thereof. When each of these stapling
mechanisms is carried to the point where it is brought into contact with the wire,
the wire guided by the channel 414, and held by the pressing wheel 408, will be
engaged by said mechanism, and lie in the slight grooves of the arms 412, 411,
and setting bed, 444, between them, the cutter 401 and clamping jaw 409 then
standing in their outward or open positions, as in Figure 75.
When the proper point has been reached in the revolution of the carrier, the
forward end of the wire being in proper relation to the stapling mechanism, the
shoe 435 of the arm 432, which has, in its circular travel, come into contact with
the under or operating face, of the horn 436, is depressed thereby, tiíus simul-
taneously rocking the clamping jaw 409 down onto the wire lying in the arms 412,
411, and setting bed 444, as in Figure 68, and forcing the cutter 401 into contact
with said wire, which, in connection with the arm 411, severs a wire length
therefrom.
The stapling tools, with the clamping jaw 409 holding said detached wire length
by pressing the same onto the setting hed, now travel onward in their rotative
movement toward the setting point, which is at or near the place where the carriers
A, B, most nearly approach each other, and while thus moving from the point
where the wire length was detached to the setting point, the following operation
will take place, caused by the cam S¹.
The armi 411, 412, will be moved outwards by the operation respectively of the
rock arms 423, 426, as in Figure 70 which movements may be simultaneous, nearly
so, or successive thus operating to bend the ends of the wire lengths at angles to
the crown, the jaw 409 operating as a bending anvil, and the inclination hereto-
fore described of these legs will thus be imparted to them, said legs then being
sustained by lying in slight grooves in the inside faces of the arms 411, 412, as
is well understood in this art.
As the setting point is being approached, the arm 412, by the shape of the
cam 501, will be withdrawn so as not to protrude beyond the periphery of the
carrier A, as shown in Figure 71, and the staple leg which the arm 412 and

page_text: the jaw 409 then supports, will be carried into contact with a setting die 413,
and, by the rolling pressure caused by the nearer approach of the carriers A, B,
said leg will be bent downward toward the crown of the staple, as in Figure 71,
and when the staple leg, supported by the jaw 409 and the arm 411, is, by the
further movement of the carriers brought into contact with said setting die, and
by the rolling contact and nearer approach of the said carriers A, B, this leg is
bent toward its ultimate clinched position, said arm 411 will 'be retracted or drawn
within the carrier A by the operation of the cam 500, and as soon as, or after,
the staple legs are in contact with the setting die, according to the construction
of the parts, the shoe 435 will leave the horn 436, and thus relieve the clamping
jaw and cutter, so that the same may be retracted by the action of the spring 433.
As the carriers, A, B, continue to move, and carry the stapling mechanisms
beyond the clinching point, the staple will have been completely clinched, its
crown lying on one side and its legs on the other side of the material operated
upon, which, thus fastened together by the staple, will be carried onward for
delivery to the mechanisms which are to subsequently operate upon it, and each
succeeding stapling mechanism will, in like manner, operate to form a staple,
carry it to the setting point, and set and clinch the same in the material, thus
successive staples being formed and set in the material operated upon, and binding
it together with a continuous longitudinal seam.
Where the product consists of a large number of leaves or sheets or packs of
folded material, bound together on their outer edge (that edge nearest to the
observer in Figure 67), the same will be bound in book-like form, and only
require to be cut into suitable lengths and delivered. Of course, these cutting
mechanisms might be combined with the carriers A, B, but as it is sometimes
desirable to impart a further longitudinal fold to the stapled material before it is
severed transversely, it is preferable to provide a cutting mechanism separate from
the carriers A, B.-In this instance, such cutting mechanism is shown as provided
in the carriers C¹, D.-These carriers C', D', are shown to be provided with
cutting mechanisms constituted by cutting knives, 475, and cutting recesses or
sockets, 476, by which the passing material will be severed transversely.
In addition to the cutting device with which the carriers C, D₁, are provided,
they may also carry folding mechanisms, by which the stapled product passing
between them will be given a transverse fold. The subsequent longitudinal
folding of the stapled material heretofore referred to, is provided for herein by the
secondary longitudinal folder, represented herein by its internal guide or fornier G,
and external turners 498, 499. This secondary folder may be made laterally
adjustable to conform to any lateral adjustment of the stapling mechanism.
In order that the stapling mechanisms may cooperate with a subsequent longi-
tudinal folder, as the secondary longitudinal folder described, or with primary
longitudinal folders, or other web or sheet producing or delivering mechanism,
the said stapling mechanisms are provided with means for their adjustment
longitudinally with respect to said primary and secondary mechanisms. Thus,
the carriers A, B, are respectively secured to the shafts, which revolve them by
being splined thereon, and provided with holding screws to secure their position
of adjustment on said shafts.
The cam S¹, by means of which the moving mechanisms in the carrier A are
operated, has its bracket arranged to slide on, or in a way in, the cross bar 485.
The bracket 486 carrying the wire guide 441 and the feeding rollers 442, 443, is
arranged to slide in the cross har 472, as is also the arm or horn 436, and the
wire spool 440 is likewise adjustable on its supporting rod 445, all of these parts
being capable of being secured in any position of their adjustment. When the
stapling mechanism is arranged in the centre, as is shown in Figure 69, the
compound product will be stapled centrally in its passage between the car-
riers A, B, and, thus stapled, will pass under the roller 473, over the roller 474,
and onward over the secondary longitudinal folder, by the operation of which it
will be folded or doubled centrally on its longitudinal stapled line, and, thus

page_text: bound and folded, it will be passed through a cutting mechanism, for severing
it transversely into suitable lengths, as betore described, or it may pass between
carriers, as C, D, provided with both cutting and folding mechanisms, as will
be readily understood. Of course, a great variety of delivery mechanisms may
be used for dealing with this stapled web, and, according to its intended use, it
may be delivered in long lengths, and rolled up or lapped in zig-zag folds, or be
cut into short lengths, as may be desired.
A printing machine has been referred to herein as a means for producing webs
which are plicated by the longitudinal folder shown, but it is to be understood
that the material to be bound together by a running line of staples may be fed to
this stapling mechanism in any manner, and such material may be in the form
of packs of sheets or webs suitably fed thereto by any mechanism suitable for the
purpose, and said mechanism may be capacitated to associate the webs or sheets
either with doubled or raw edges, or in packs of either.
Carriers A, B, need not have a continuous surface, although that is a con-
venient form, especially where a multiplicity of stapling mechanisms are used,
as herein. If carrier B is so made as only to amount to merely a carrier for the
stapling mechanisms, a conductor plate, having a groove 414, extending between
the feeding rollers 442, 443, and the wire-severing point, may be added, if found
necessary.
Referring to Figures 76 to 83, which illustrate a machine embodying another
modification of the invention,
Figure 76 is a front elevation of the delivery of a printing machine embodying
this part of the invention some of the parts being broken away.
Figure 77 is a side elevation of the same, the point of view being indicated
by the arrow 77 in Figure 76.
Figure 78 is a section on an enlarged scale, showing parts of the mechanism
on the line 78, 78 of Figure 77.
Figure 79 is a section on an enlarged scale on the line 79-79 of Figure 78,
the point of view being to the left of the line.
Figure 80 is a plan, on a larger scale, of the stapling mechanism, the point of
view being indicated by the arrow 80 in Figure 78; and
Figures 81, 82, and 83, are sectional views similar to Figure 78, showing
different positions of the parts,-Figure 81 showing the staple as nearly formed,
Figure 82 showing the formed staple placed upon the setting bed and gripped
there by the holding device or swinging jaw, and Figure 83 showing the staple
as being clinched, the holding device undergoing retraction.
Referring to said Figures 76 to 83, the web or webs of paper, M, are led to the
stapling mechanism from any appropriate printing and folding or associating
mechanism, between the carriers A, B, which support the stapling mechanism,
and which may also carry cutting and folding mechanisms, although of course,
if preferred, the cutting and folding operations may be performed by other means.
The paper may be presented to the stapling mechanism in the form of webs or of
sheets. The particular form of such mechanism herein shown, but to which this
part of the invention is not in any way limited, is the longitudinal web folder of
my patent aforesaid, of which 560 and 570 are the nipping or folding rollers.
The staples in connection with which the present invention is to be used, may
be formed outside of the machine, and merely set in the material by the machine,
or they may be formed in the machine itself, as well as set. The machine shown
herein is of the character which both forms and sets the staples. The mechanism
shown is also one in which the staples are set with their legs in a line transverse
to the run of the fabric being stapled. It will of course be understood that the
invention may be applied to a machine in which the staples are set with their
legs in range with said line of movement. In the machine shown in these
figures, as usual in machines of like character, several separate stapling
mechanisms are arranged side by side upon the carrier A. As these mechanisms
are precisely alike, it will be understood that the description herein applies to

page_text: .
each of them, although the parts are referred to, for convenience, as in the
singular rather than in the plural number.
The wire for forming the staples is led from the spool S between the feeding
rollers 502, 503, which rollers are moved from the worm wheel 504, and thus passes
under the fixed anvil 505, and in front of abutment 506, in manner similar to
that described in the specification of the before-mentioned patent. The wire is
then severed by a knife of the usual construction, not shown, and is formed by
being swept along the eccentrically curved face of the anvil 505 by the bender or
former 507, which is reciprocated in a recess in the carrier by an arm 508,
mounted on the rock shaft 509, provided with a rock arm 510, operated by
cam 511. Before leaving the anvil, the legs of the staple are given a converging
inclination by the plates 512, 512, and in then deposited by the retiring bender
upon the setting bed 513, preferably at a point 514 where a groove is adapted to
receive it and hold it during the operation of setting.
a fixe‹l
The staple formed in this, or any other manner, having been placed upon the
setting bed, the device which constitutes this part of the present invention now
comes into action, to hold the staple in position while it is penetrating the material.
It is obviously necessary that the staple former 507 should be retracted into its
socket when it reaches the point at which the two carriers are nearest in contact,
and to prevent interference with the material, it is desirable that this movement
should not be caused by direct impact with the surface of the opposite carrier,
but that the former should be positively withdrawn before such impact is possible.
This withdrawal must be so made, if contact between the staple former and the
material being stapled is to be avoided, as to leave the staple inadequately
supported. This part of the invention consists of means for holding the staple in
the position in which its legs may be forced through the material, which means
are of such a character, and so operated, as not to come in contact with the material
being stapled. The form of the invention shown in this part of the application,
to which, however, it is not limited, is that of a swinging jaw, 515, mounted on
short shaft, 510, bolted to the frame-work of the cylinder, between the legs of the
bender 507. This jaw is rocked on its shaft by an arm 517 mounted upon a rock
shaft 518, which is provided with a rock lever 520 carrying a bowl which is con-
trolled by the overhanging cam 521, fixed to the frame (see Figure 77). This cam
is so shaped that, as soon as the staple is deposited upon the setting bed by the
retiring staple former, the swinging jaw advances to the position shown in
Figure 82 its lip passes over the crown of the staple, and holds it in the groove
in the setting bed until the legs of the staple have penetrated the material being
stapled, and the staple is therefore held in position by the material, when the
swinging jaw is withdrawn, as appears in Figure 83, and the clinching of the
legs of the staple follows by means of a clinching die 522, which may be either
movable or stationary, and in this case is shown as mounted upon the carrier A.
The lip of the jaw 515, which engages the staple, is preferably flat, and of about
the width of the staple crown, so that it effectually prevents buckling of the crown
while the staple is being driven.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed (as communicated to me
from abroad), I declare that what I claim is:-
1. The combination with stationary plates having bending arms, and provided
with eccentric guiding channels for the staple legs, of a forming anvil rotating
between said plates, and bearing against the staple crown, whereby the staple,
while carried onward, is caused to traverse the face of the anvil by the travel of its
legs in said channels, substantially as described.
2. The combination with means for feeding staples thereto, of a staple holder
or presenting tool provided with opposed guiding channels for the staple, enlarged
at its point of reception thereof, so as to receive and support a staple with its legs
spread apart, or at obtuse angles to its crown, substantially as described.
3

page_text: 3. The combination of means for feeding staples thereto, with a staple holder or
presenting tool having opposed longitudinal guiding channels for the staple legs,
an opening cut through one side of said holder, and intercepting said guiding
channels, to admit the passage of the staple thereto, said guiding channels being
enlarged laterally at the receiving point, whereby a formed staple may be delivered
into said holder with its legs at right angles, and be retained therein by the
spreading apart of its legs at obtuse angles, substantially as described.
4. The combination of means for feeding a staple thereto and a staple driver or
inserting tool reciprocating therein, with a staple holder or presenting tool having
opposed longitudinal guiding channels for the staple legs, an opening cut through
