Improvements in Stapling and Delivery Mechanism 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 to be as follows:-
This invention relates to deliveries for printing presses, and provides for the
severance of one or more folded or associated webs into sheets of varying lengths,
the passage of said sheets through the machine in the packs into which they are
severed by the cutting mechanism, or the collection of the same into larger packs,
as desired; the fastening of said packs together by wire staples at their ultimate
line of fold; the folding of the packs on the stapled lines; and the final delivery of
the same.
It also relates to the mechanism for inserting the wire staples into the
sheets or packs of sheets, and includes improvements in such mechanism,
respect to said stapling mechanism, the present invention contains improvements
upon the British Patent No. 3394 of 1893 granted to the present applicant.
In
It is well known that it is frequently desirable, in delivering printed products, to
vary the size of the pages, aud the number of sheets collected, and this is particularly
the case in the printing of pamphlets, in connection with which a wire stapling
mechanism is signally serviceable.
It is one of the principal objects of the present invention to so construct the
delivery that changes in the product, as regards the size of the sheet and the number
of sheets collected, or in regard to either of these features by itself, may be made
quickly and conveniently.
To that end, there is provided a carrier, to which are led webs from any suitable
printing press, and which supports a member or members of one or more cutting
mechanisms, with which co-operate other members mounted upon an adjacent
carrier, for cutting the web into sheets.
Upon the first mentioned carrier, or upon another carrier further on, are mounted
pins for seizing the leading ends of the severed sheets and folding blades, for
folding the sheets off from the carrier. The second carrier mentioned, or a carrier
further on, so placed as to co-operate with the carrier supporting the pins and
folding blade, is provided with a stapling mechanism for wiring the sheets. This
stapling mechanism embraces mechanism for forming and setting staples and wire-
feeding mechanism for presenting the wire to the staple-forming mechanism.
Provision is made for varying the length of sheets severed, by mounting the
cutting mechanisms removably so that they may be introduced or removed so as to
sever the web at shorter or greater intervals. The staple-forming and setting tools
are also furnished in several sets, and are made removable and interchangeable
with members of the cutting mechanism, so that their number can be varied to

page_text: accord with the length of the sheets into which the web is cut. Likewise, the
folding blades and pins are made removable and changeable to a sufficient extent
to adapt the folding and collecting carrier to manipulate sheets of varying lengths.
The delivery will be adjusted by means of these removable and interchangeable
mechanisims, before its operation begins, to the length of sheets which it is desired
to produce.
The collection and non-collection of sheets upon the collecting carrier is con-
trolled by the pins and the folding blades mounted on said carrier. Mechanism is
provided whereby, when it is desired to run sheets uncollected, the pins are with-
drawn, to release each sheet or pack of sheets, and the folding blades are operated
to fold each sheet, or pack of sheets, successively at the proper times, and these
mechanisms are adapted to be applied either to full-width or half-width sheets.
Mechanism is also provided whereby, when it is desired to collect sheets upon
the carrier, the releasing action of the pins, and the folding action of the folding
blades, may be intermitted while the sheets are being collected. These several
mechanisins are also made controllable, so that sheets of any width to which tho
machine is adapted may be delivered collected or uncollected, as desired, and in
every case stapled.
As above stated, the staple forming and setting mechanism is mounted upon a
carrier co-acting with the collecting carrier, and operating to insert the wire
staples into collected or uncollected sheets while they are carried upon the collecting
carrier. As stated above, the stapling mechanism is adjusted, before the operation
of the machine begins, to the length of sheets of which the product is to be made
up, this adjustment consisting in the determination of the number of stapling
mechanisms on tools in the machine. The action of the stapling mechanisin, to
provide for changes as regards the collection and non-collection of sheets, may be
determined by the feed of wire thereto.
Provision is made for so regulating the feed, that when sheets of minimum
width uncollected are being passed through the machine, a given amount of wire
will be furnished to the stapling mechanisms, which is obviously the maximum
quantity which the machine will require, and a controlling mechanism is provided
whereby the amount of wire fed to the stapling mechanisms may be reduced
proportionately to the reduced demands of the latter, dependent upon changes in
the width or the collection of sheets. Thus, where sheets of half width, collected,
or of full width, collected or uncollected, are being produced, less amounts of wire
will be required than where the sheets are of half width uncollected, and a different
amount of wire will be required in each case. The controlling mechanism is so
constructed as to furnish the precise quantity of wire needed in every instance, its
operation depending upon an adjustment made before the machine begins to
deliver. The staple-forming and setting mechanism will of course go through the
motions of forming and setting the staple at each revolution of the carrier to which
they are attached, but it is obvious that these motions will be ineffective, unless the
wire is present for forming the staple, and that therefore control of the wire feed
is virtually control of the stapling mechanism, so far as practical results are
concerned.
In the above form of construction, reference has been made to the operation of
collecting, as being performed upon the same carrier in which are mounted the
folding blades: This, however, need not be the case, since a separate carrier may
be utilized for the purpose of collection, and the packs of sheets collected upon the
latter carrier may be delivered to the folding carrier. When this construction is
employed, and it is desired to produce an uncollected product, the sheets are passed
directly to the folding carrier, without interference by the collecting carrier. When
the sheets are to be collected, pins mounted upon the collecting carrier are thrown
into operation by means of a cam movement, brought into action once in a given
number of revolutious of the collecting carrier, this being accomplished by a
suitable change gearing connecting the pin can of the collecting carrier with the
driving shaft of the machine, which gearing is so adjusted as to produce the

page_text: requisite motion of the pin cam, to operate the collecting pins at suitable intervals.
It is also feasible to contro! the wiring of the sheets, by controlling the operation
of the staple-forming and setting mechanism, instead of controlling it exclusively
by the feeding of the wire, and an appropriate means for this purpose may be
provided, as, for instanco, the staple-forming and setting mechanism may be
normally operated at each revolution of the stapling carrier by a cam; and a
second cam may be provided, having a suitable interval of rotation, different from
that of the stapling carrier, which shall interpose to co-operate with said cam, to
cause the operation of the stapling mechanism to intermit, during one revolution,
or the required number of revolutions of the staple carrier. In conjunction with
this modified construction of the stapling mechanism, devices may be employed for
varying the speed of the wire feed, as by change gearing, or for suspending or
intermitting the feed. Provision may also be made for feeding the wire by hand,
independently of the driving connection of the feeding mechanisin with the
machine, which is desirable for testing and adjusting the stapling devices.
In connection with the mechanism for collecting sheets above described, it is
proposed to introduce a separate series of sheets to be applied to and stapled with
the packs of sheets above described, as a cover thereto, when it is desired to
produce a covered product. To this end, it is proposed to provide means for
severing the web into sheets, and feeding the sheets to the collecting carrier, or to
the folding carrier, so that the sheets shall lie beneath the packs of sheets above
referred to, and be folded so as to cover the same.
After the product has been stapled and folded, as above described, it may be
switched to a second folding mechanism, or be carried to a fly or other delivery.
It is also proposed to provide means for slitting the web or webs, before they
reach the collecting, stapling, and folding mechanisms, into a number of narrow
webs, associating these webs, and passing the associated webs, through the series
of operations, or a part of them, above mentioned.
In the mechanism for forming and setting the staples in collected or uncollected
sheets, the present invention includes various improvements.
The staples in this mechanism are formed by bending arms sweeping along the
curved face of a stationary anvil, the wire being severed by a knife while it is held
between the bending arms and the anvil. It is desirable that the wire, while being
cut, should be held more firmly than is possible where the bending arms and the
tools have a plane surface, and to that end, in the machine built according to the
present invention, it is proposed to provide abutment surfaces upon the faces of
the bending arms, and upon the face of the anvil, either or both of which abutments
shall serve to assist in holding the wire firmly while being cut. The abutment on
the anvil may be preferably formed by a central rib projecting from the face of the
anvil. It is also proposed to make a portion of the anvil spring-seated, in order that
it may yield to allow the wire to be carried past the abutment upon it, after the wire
bas been severed. There is also provided means connected with the bending arms,
for lifting the wire length into contact with the abutment on the anvil, which means
may consist of inclined surfaces; also a spring or plate guard, to prevent displace-
ment of the staple while being formed; also a fixed staple setting bed, coinciding
with the surface of the carrier; also improvements in the cap for closing the
aperture through which the stapling tool passes into and out of the carrier, aud
guiding ways for the bending arms.
It is desirable, in a machine for setting wire staples, that the legs of the staple
should be given an inward bend somewhat beyond a position at right angles to the
staple crown, before the staples are inserted in the material to be stapled, and to
that end, in the present invention, it is proposed to provide the staple-bending anvil
with side grooves and deflecting plates, by which this additional bending is given to
both legs of the staple. The staple-forming and bending tool may be operated by
a cam fixed to a shaft coincident with the axis of rotation of the carrier.
It is also desirable to provide for a very nice adjustment of the setting or
clinching bed against which the legs of the staple are clinched, and in the present

page_text: invention it is proposed to provide means for such nice adjustment, which may, if
desired, be in the form of an adjusting screw provided with an eccentric.
This invention also includes improvements in the mechanism for controlling the
movement of the plunger carrying the bending arins. It is proposed to give this
plunger a positive motion inward, by means of an adjustable cam-actuated rock-
arm.

Improvements in Stapling and Delivery Mechanism 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 :-
This invention relates to deliveries for printing machines, and provides for the
severance of one or more folded or associated webs into sheets of varying lengths,
the passage of said sheets through the machine in the packs into which they are
severed by the cutting mechanisin, or the collection of the same into larger packs,
as desired, the fastening of said packs together by wire staples at their ultimate
line of fold, the folding of the packs on the stapled lines, and the final delivery of
the same. It also relates to the mechanism for inserting the wire staples into the
sheets, or packs of sheets, and includes improvements in such mechanism. In
respect to said stapling-mechanism, the present invention contains improvements
upon Patent No. 3394 of 1893.
It is well known that it is frequently desirable, in delivering printed products, to
vary the size of the pages and the number of sheets collected, and this is particularly
the case in the printing of pamphlets, in connection with which a wire stapling
nechanism is signally serviceable.
It is one of the principal objects of the present invention, to so construct the
delivery, that changes in the product, as regards the size of the sheet and the
number of sheets collected, or in regard to either of these features by itself, may be
inade quickly and conveniently.
To that end, there is provided a carrier to which are led webs from any suitable
printing machine, and which supports a member or members of one or more cutting
inechanisms with which cooperate other members mounted upon an adjacent carrier,
for cutting the web into sheets.
Upon the first mentioned carrier, or upon another carrier further on, are mounted
pins for seizing the leading ends of the severed sheets, and folding blades for folding
the sheets off from the carrier. The second carrier mentioned, or a carrier further
on, so placed as to cooperate with the carrier supporting the pins and folding blade,
is provided with a stapling mechanism for wiring the sheets. This stapling
mechanisin embraces mechanism for forming and setting staples, and wire feeding
mechanism for presenting the wire to the staple-forming mechanism.
Provision is made for varying the length of sheets severed, by mounting the
cutting mechanisms removably, so that they may be introduced or removed, so as to
sever the web at shorter or greater intervals. The staple-forming and setting tools
are also furnished in several sets, and are made removable and inter-changeable with
members of the cutting mechanism, so that their number can be varied to accord

page_text: with the length of the sheets into which the web is cut. Likewise, the folding blades
and pins are made removable and changeable to a sufficient extent to adapt the
folding and collecting carrier to manipulate sheets of varying lengths. The delivery
will be adjusted by means of these removable and interchangeable mechanisms, before
its operation begins, to the length of sheets which it is desired to produce.
The collection and non-collection of sheets upon the collecting carrier is con-
trolled by the pins and the folding blades mounted on said carrier.
Mechanisin
is provided whereby, when it is desired to run sheets uncollected, the pins are
withdrawn to release each sheet or pack of sheets, and the folding blades are
operated to fold each sheet or pack of sheets successively at the proper times,
and these mechanisms are adapted to be applied either to full-width or half-width
sheets.
Mechanism is also provided whereby, when it is desired to collect sheets upon
the carrier, the releasing action of the pins, and the folding action of the folding
blades, may be intermitted while the sheets are being collected. These several
mechanisms are also made controllable, so that sheets of any width to which the
machine is adapted may be delivered collected or uncollected, as desired, and in
every case stapled.
As above stated, the staple forming and setting mechanism is mounted upon a
carrier co-acting with the collecting carrier, and operating to insert the wire staples
into collected or uncollected sheets, while they are carried upon the collecting carrier.
As stated above, the stapling mechanism is adjusted, before the operation of the
machine begins, to the length of sheets of which the product is to be made up, this
adjustment consisting in the determination of the number of stapling mechanisms or
tools in the machine. The action of the stapling mechanism, to provide for changes
as regards the collection and non-collection of sheets, may be determined by the feed
of wire thereto.
Provision is made for so regulating the feed, that when sheets of minimum
width uncollected are being passed through the machine, a given amount of
wire will be furnished to the stapling mechanisms, which is obviously the maximum
quantity which the machine will require, and a controlling mechanism is provided
whereby the amount of wire fed to the stapling mechanisms may be reduced propor-
tionately to the reduced demands of the latter, dependent upon changes in the width
or the collection of sheets. Thus, where sheets of half width, collected, or of full
width collected or uncollected, are being produced, less amounts of wire will be
required than where the sheets are of half-width, uncollected, and a different
amount of wire will be required in each case. The controlling mechanism is so
constructed as to furnish the precise quantity of wire needed in every instance, its
operation depending upon an adjustment made before the machine begins to deliver.
The staple-formning and setting mechanism will of course go through the motions of
forming and setting the staple at each revolution of the carrier to which they are
attached, but it is obvious that these motions will be ineffective unless the wire is
present for forming the staple, and that therefore control of the wire feed is virtually
control of the stapling mechanism, so far as practical results are concerned.
In the above form of construction, the operation of collecting is referred to as being
performed upon the same carrier in which are mounted the folding blades. This,
however, need not be the case, since a separate carrier may be utilized for the purpose
of collection, and the pack of sheets collected upon the latter carrier may be delivered
to the folding carrier. When this construction is employed, and it is desired to
produce an uncollected product, the sheets are passed directly to the folding carrier
without interference by the collecting carrier.
When the sheets are to be collected, pins mounted, upon the collecting carrier are
thrown into operation by means of a cam movement brought into action once in a
given number of revolutions of the collecting carrier, this being accomplished by a
suitable change gearing connecting the pin can of the collecting carrier with the
driving shaft of the machine, which gearing is so adjusted as to produce the requisite
motion of the pin cam to operate the collecting pins at suitable intervals. It is also

page_text: feasible to control the wiring of the sheets by controlling the operation of the staple-
forming and setting mechanism, instead of controlling it exclusively by the feeding
of the wire, and an appropriate means for this purpose may be provided, as, for
instance, the staple-forming and setting mechanism may be normally operated at
each revolution of the stapling carrier by a cam; and a second cam may be provided
having a suitable interval of rotation, different from that of the stapling carrier, which
shall interpose to co-operate with said cam to cause the operation of the stapling
mechanism to intermit during one revolution, or the required number of revolutions,
of the staple carrier. In conjunction with this modified construction of the stapling
mechanisin, devices may be employed for varying the speed of the wire feed, as by
change gearing, or for suspending or intermitting the feed. Provision may also be
made for feeding the wire by hand, independently of the driving connection of the
feeding mechanism with the machine, which is desirable for testing and adjusting
the stapling devices.
In connection with the mechanism for collecting sheets above described, it is
proposed to introduce a separate series of sheets to be applied to and stapled
with the packs of sheets above described, as a cover thereto, when it is desired
to produce a covered product. To this end, it is proposed to provide means for
severing the web into sheets, and feeding the sheets to the collecting carrier or
to the folding carrier, so that the sheets shall lie beneath the packs of sheets
above referred to, and be folded so as to cover the same.
After the product has been stapled and folded as above described, it may be
switched to a second folded mechanism, or be carried to a fly or another
delivery.
It is also proposed to provide means for slitting the web or webs, before they
reach the collecting, stapling, and folding mechanisms, into a number of narrow
webs, associating these webs, and passing the associated webs through the series
of operations, or a part of them, above mentioned.
In the mechanism for forming and setting the staples in collected or uncollected
sheets the present invention includes various improvements.
The staples in this mechanism are formed by bending arms sweeping along the
curved face of a stationary anvil, the wire being severed by a knife while it is held
between the bending arms and the anvil. It is desirable that the wire, while being cut,
should be held more firmly than is possible where the bending arms and the
tools have a plane surface, and to that end, in the machine built according to the
present invention, it is proposed to provide abutment surfaces upon the faces of
the bending arms, and upon the face of the anvil, either or both of which
abutments shall serve to assist in holding the wire firmly while being cut. The
abutment on the anvil may be preferably formed by a central rib projecting from
the face of the anvil. It is also proposed to make a portion of the anvil spring-
seated, in order that it may yield to allow the wire to be carried past the abutment
upon it, after the wire has been severed. Means are also provided, connected with
the bending arms, for lifting the wire length into contact with the abutment on the
anvil, which means may consist of inclined surfaces; also a spring or plate guard to
prevent dis-placement of the staple while being formed; also a fixed staple-setting
bed, coinciding with the surface of the carrier; also improvements in the cap for
closing the aperture through which the stapling tool passes into and out of the
carrier; and guiding ways for the bending arms.
It is desirable, in a machine for setting wire staples, that the legs of the staple
should be given an inward bend somewhat beyond a position at right angles to the

This invention also includes improvements in the mechanism for controlling the

plunger a positive motion inward by means of an adjustable cam-actuated rock-
arın.

The invention is shown herein as applied to the delivery apparatus of a web
printing machine. One of the principal parts of this delivery apparatus is a
longitudinal folder consisting of an internal guide L, external turners 50, 60, and
fold-laying rollers 70, 80, as is common. The longitudinally folded web is delivered
between rotary cylinder carriers A, B, which are provided with cutting mechanisms
to sever the web transversely into sheet-lengths, sheet or web controlling pins by
which the paper is carried to proper position to be acted upon and released as
required, and rotating folding blades mounted in the carrier A, that co-operate with

provided with mechanism whereby it is made capable of collecting many sheets upon
its surface into packs.
These carriers are further provided with means for stapling together the plies of
the product which they aid in making. From the folding rollers there are provided
two pathways for the delivery of the product, one of which is directly vertical to the
arms of the rotary fly S, and the other in a lateral direction, whereby the transverse
folded products may be conveyed to a second folding mechanism, to receive other
folding, if desired, these two pathways being controlled by means of a switch 40,
whose exact position is determined by the position of the adjusting arm 41, which
is regulated, as desired, by the pin 42.
The moving mechanisins of this delivery apparatus are geared and driven in proper
direction, and relative speed, by ordinary gearing, enough of which is illustrated to
indicate the movements, and which needs no especial description beyond such as is
hereinafter made in order to explain peculiar constructions.
This delivery apparatus is designed, as above pointed out, to cut, fold, staple, and
deliver, various products. The products which are produced by the special con-
struction of delivery here shown (leaving out of view for the present the variations
produced by the use of the switch 40 and the additions to the machine shown in
Figures 32, 33, 34) are:-
1.-The product shown in Figure 35, that is, consisting of eight pages of full
width.
2. The product consisting of sixteen pages of the size shown in Figure 35.
3.The product consisting of eight pages, such as are shown in Figure 36, the
pages being of half width of products 1 and 2.
4. The product consisting of sixteen pages of the same width as shown in
Figure 36, or product number 3.
The web is severed longitudinally at the centre, as shown in Figure 32, and the
two halves associated and carried to the carriers A and B. The length of the pro-
The width of the
ducts numbered 1, 2, 3, and 4, is the width of this severed web.
pages of these products depends upon the cutting and other mechanisms provided
in the carriers A and B. The width of the page presented by products 1 and 2 is
one half the circumference of the carrier A, the sheet being the full circumference of
this cylinder, and in making this product, the cutting mechanism is arranged to
sever the web once in each revolution of the carrier A.
The width of the pages in products 3 and 4, represents one quarter of the circum-
ference of the carrier A, the full sheet of these products being half of the circum-
ference of the carrier A, and the cutting mechanism being arranged to sever, the
web twice during each revolution of the carrier A, to produce this product.

page_text: Product number 1 will be, it is seen, made up of the two associated sheets of paper
severed at each revolution of the carrier A, once folded transversely, and united at
the fold by staples.
Product number 2 consists of two sets of two sheets each set similar to the two
sheets of product number 1, collected, stapled, and folded once transversely.
Products number 3 will be, it is seen, made up of two associated sheets of paper,
two sets of which are severed at each revolution of the carrier A, once folded trans-
versely, and united at the fold by staples.
Product number 4 consists of two sets of two sheets, each set similar to the two
sheets of product number 3, collected, stapled, and folded once transversely.
In order to produce these several products it is evident that two changes of con-
dition are to be provided for, first, the change from the non-collected to the collected
product, or vice versa, whatever may be the width of the sheet, and second, the
change from the wide to the narrow product, or vice versa, whether the sheets be
collected or non-collected.
The mechanism which is devised for meeting the requirements of these changes,
will now be described.
The carrier A is provided with two sets of folding blades, two sets of pins, and parts
of two sets of cutting devices, to provide for the severing of sheets twice during each
revolution of the carrier and the manipulation of these sheets, this construction being
illustrated in Figure 9. The co-acting cylinder B has a corresponding construction,
as is also shown in this figure, it being provided with two knives, which co-act with
the notched plates in the carrier A, and with two sets of stapling devices.
In order to adapt these cylinders to the production of the wide as well of the narrow
product, the folding blades are mounted upon a removable frame, as indicated in
Figure 9, and when it is desired to change from a wide to a narrow product, one of the
sets of folding blades is removed, and, in place thereof, a set of pins carried by a
similar frame is inserted, as shown in Figure 8. The two sets of pins originally in
the cylinder are now locked in their withdrawn position, and the cylinder equipped
as shown in Figure 8 is adapted to manipulate and fold sheets of the length of the
circumference of the carrier.
A corresponding provision for such a change is made in carrier B, by mounting the

change the mechanism to the cutting and stapling of sheets of full width, the two
knives are removed, and replaced by dummies, and one of the stapling mechanisms
is removed and replaced by a block carrying a knife. The cylinder B is then in a
condition to staple and cut sheets of full width, as shown in Figure 8.
The pins reciprocate, as usual, in slots 2 in the frame of the carrier, and are
connected with arms 3 on rock shaft 4. The usual springs 31 are provided, as
indicated in Figure 7, for holding the pins normally in a projecting position, and
they are withdrawn by the contact of bowls 31 on crossheads 321 with a cam 32,
which will be hereafter described.
The folding blades are mounted upon a shaft, as best shown in Figure 15, and
are made in sections, in order to clear the staple benders, as the two pass at and near
the point at which the carriers A, B, are in closest proximity to each other. The.
shaft of the folding blades is provided at one end with a cross-head 54, which
carries bowls that travel within a circular guard 55, and engage at the proper times
with cam 56, to throw the blades out to fold the sheets, as will be hereafter
explained.
The stapling devices will now be described. Referring to the vertical cross
section of the carrier B shown in Figure 12, it will be seen that the shaft 5 of
this cylinder upon which its driving gear wheel 6 is mounted, is short, it being
bolted to the exterior framework of the end of the cylinder. The bearing of the
cylinder at the other end is secured by a hollow sleeve 7, bolted to the cylinder at
that end, and revolving in a bushing 8. Within the cylinder, and supported at one
end in the interior of the sleeve 7, and at the other end in a recess in the end of
shaft 5, is a stationary shaft 9, provided with cams 10 for operating the mechanism
B

page_text: which forms the staple, and presents it to the paper. This shaft has a flat end
(see Figure 1), which enters a hole of corresponding shape in a cap piece connected
to the frame.
The stapling tools 11 have bending arms 12, 12', projecting through the carrier
shell for forming the staple, and are provided at their inner ends with rollers 13,
which bear upon the cams 10, the tools being pressed inward by springs 14 seated
in the carrier frame, or in the blocks 15 carrying the stapling tools.
The stapling
tools are held in position by screws 16, which pass through slots 17 in the tools.
The faces of the arms 12, 121, may be provided with an abutment 18, 181, as
shown, for holding the wire length in contact with a corresponding abutment 19 in
the face of the curved stationary anvil 34, thus holding it firmly while the wire is
being cut by the pivoted knife 35, forced upwards at the proper time by contact
therewith of the shoulder 36 upon the stapling tool.
The staple is formed by the stapling tool sweeping the wire length along the
eccentric curve of the face of the anvil 34. In order to hold the staple securely in
its position while it is being swept forward by the stapling tool, the spring or guide
piece 37, lying along the face of the anvil, is provided. The front end of the anvil is
formed with the grooves 38, and provided with the bending plates 39, which incline
the legs of the staples inward beyond a right angle.
The staple having been thus formed over the anvil, remains in the grooves 51, 511,
formed for the reception of the legs of the staple in the interior faces of the
arms 12, 121, until the staple meets the paper, and is forced through the same, and
clinched against the clinching die 33 carried by the carrier A, the stapling tool being
at the same time forced back by its spring 14, it being permitted to re-enter the
.. carrier by the low part of cam 10.
There are, in the construction shown, four stapling mechanisms. The shaft 9 is
provided with two additional cams, and provision is made for removing the two outer
stapling tools inward, in order to change the distance apart at which the staples are
set, in accordance with the product desired.
The wire is fed from a spool 43 to each of the stapling mechanisms. The feeding
mechanisms for the wire are four in number, and are driven from the worm shaft 44.
Each consists of two feeding disks 45 and 46, the disk 45 being mounted upon a
shaft 47, which, on one end, carries a worm wheel 48, and on the other a gear 49,
which engages with a gear 58 mounted on the hub of disk 46, the gear and disk
constituting one piece journalled upon a rounded portion of the block 59.
block 59 is pivoted to the frame, as shown, and its upper end is pressed outward from
the shaft 47 by the spring 61, so as to bring the disks into nipping contact, as shown
in Figure 20.
This
Just above the block 59 is mounted, in the frame, and extending across the
machine, a rock shaft 62, provided with pins 63, which project downward below the
top of the blocks 59. When the blocks are tilted into the position shown in
Figure 19, the pins 63, through their engagement with the blocks 59, tilt the latter
until the disks 45, 46, are out of feeding engagement. The wire passes from the
spool 43 to the guide 64, thence around the feed disk 46, and between it and the feed
disk 45, and thence under the anvil 34, and just, behind the abutment 19, and above
the spring 37, where the wire length is severed by the action of the knife 35, and
formed into a staple by the action of the stapling tool, as heretofore described.
It will be seen that whether or not, the wire-feeding mechanism feeds the wire,
depends upon the position of the rock shaft 62, and this is determined in accordance
with requirements of the machine by the arm 66 of suitable weight to hold it in
proper position, having a roller 68, which runs upon one or the other of the
cams 71, 72, 73, or upon the surface of the cylinder, at the point 74, the arm 66 being
adjustable lengthwise of the shaft, for the purpose of regulating the feed of the
wire.
When the machine is forming a product made up of half-width non-collected
sheets, viz. product number 3 above referred to, the feed of the wire is continuous,
and to permit it to be so, the roller 68 runs on the surface of the carrier, as shown

page_text: in Figure 31. The shaft 62 is, therefore, not rocked, the block 59 is not tilted by
the pin 63, and the disks 45, 46, are in their feeding position, shown in
Figure 20.
When the machine is producing the product number 1 above mentioned, from full
width sheets not collected, but half of the wire needed for half sheets not collected is
required, and consequently, to suspend the feed of the wire half the time of each
revolution, the cam 73 is provided, extending half-way around the cylinder, and the
roller 68 runs on this cam, in this position of the machine, which rocks the shaft 62
during half of each revolution, and throws the feeding disks out of feeding engage-
ment during this time.
Figures 29 and 30 show the relative position of the cam 73, the roller 68, and the
arm 12 of the stapling tool, at the moment of cutting the wire in this adjustment
of the press.
When the machine is making a product from collected full sheets, namely, the
product referred to above as number 2, it is obvious that sufficient wire will be fed
for the staples, if the wire feeding mechanism is in operation for the time occupied
by one half of a revolution of the carrier A, which, in this case, will be one quarter
of the time which elapses between each stapling operation, that is, one quarter of the
time occupied by two complete revolutions of the carrier A.
To provide for such control of the wire-feeding mechanism, a disk 75 is provided,
which is loose on the sleeve 7, and is operated by an, independent train of gearing,
as shown, so proportioned that it makes but one revolution in the time occupied by
the carrier A in making two revolutions. This disk is of the same size as the carrier,
and carries two cams 71, 72. The cam 71 has a raised portion extending three-
fourths of the way around the disk, as shown in Figure 26.
For that adjustment of the machine under consideration, the roller 68 is placed to
run on this cam, and it therefore causes the shaft 62 to be tilted during three-fourths
of each two revolutions of the carrier A, and therefore interrupts the feed of the
wire during the same period, permitting the wire to be fed during the time
occupied by a half revolution of each two revolutions of said carrier, which is the
feed of wire required by the machine in this adjustment.
The relation of the cam 71 and the roll 68, when the feed of the wire has just
terminated, and therefore at the moment of cutting in this adjustment, is shown in
Figure 27, and in Figure 26 the relation of the parts is shown at one full revolution
of the carrier A thereafter.
When the machine is engaged in producing the product above referred to as
number 4, froin narrow collected sheets, it is apparent that sufficient wire to meet
the demands of the machine will be fed during a single revolution of the cylinder.
The disk 75 is accordingly provided with a cam 72, of which the raised portion
occupies one half of the circumference of the disk, as shown in Figures 21 to 24, and
the roller 68 is placed, in this adjustment of the machine, to ride on this cam, as
shown in Figures 21 to 25.
The relations of the roller 68 and the cam 72 for this adjustment of the machine
is shown in Figure 21 at the moment of cutting the first wire length; in Figure 22
at the moment of cutting the second wire length; in Figure 23 at the middle point
of the collecting revolution of carrier A; and in Figure 24 at the end of the collecting
revolution of carrier A.
It will be observed that there is no provision for suspending the operation of the
stapling tool during the collection of sheets on the carrier A, but it will also be
observed that the operation of this tool, in the absence of wire for the formation
of a staple, will have no effect upon the operation of the machine or upon the
product.
The mechanism for operating the folding blades and pins will now be described.
For operating the folding blades, there is provided a cam 56, with which the
bowls 53, 53, of the cross head 54 come into contact, to turn the folding blades out-
ward. This cam 56 is attached to a block 57, which depends upon the axle of the
carrier A, the axle passing through an elongated hole in the block, so that the latter

page_text: is free to move vertically in suitable guides fixed to the frame. It is raised and
lowered at suitable times by means of a lever 24, one end of which is attached
thereto by means of a roll passing freely through or into a recess in the block 57
and which lever is fast upon a shaft 23. This shaft has mounted and free to rotate
thereon, a rock arm 22, the roll or stud 21 of which runs in the cam path 25, which
is formed on the inner face of a wheel 69, which rock arm may be locked fast to said
shaft 23 by a pin 26 at desired times. Said rock shaft also carries fast upon it a
segment 27, that co-acts with a segment 28 that is fast upon a shaft 29.
The wheel 69 is geared to make one revolution to two revolutions of the carrier A,
and the cam path 25 is so shaped, as shown in Figure 1, that half thereof is nearer
the centre of the axis of the wheel 69 than the other half. Consequently, during
such revolution of the wheel 69, the roller 21 is, for half the time, occupied by the
revolution, drawn toward the centre of the wheel, and during the other half of the
time is thrown further from the centre, these periods corresponding to a single revo-
lution of the carrier A.
When the arm 22, carrying the roll 21, is locked to the arm 24, connected to the
block 57, by means of a locking pin 26, the block 57, and the cam 56 attached to it,
will be depressed into the position shown in Figure 3A during the time occupied by
one revolution of the carrier A, and during the time occupied by the next revolution
of the carrier A it will be raised to the position shown in Figure 4. In the former
position, the bowls 53, 531, pass freely by the cam 56, and are not engaged thereby,
but in the latter position the folding blades are operated by the cam 56.
The mechanism for operating the pins consists of a cam 32 fixed upon an arm 81¹
which is in one piece with arm 82 and carried by stud 81, to which arm 82 is pivotted
a link 83, which link, in furn; is attached at the other end to a slotted triangular
lever 84, fast upon the rear end of the shaft 29, which carries the segment 28. The
slot 85 is provided in the lever 84, in order to permit the introduction of a bolt which
is the pivot of the upper end of link 83, and the movement of this pivot from one
angle of the lever 84 to the other. The cam 32 is located outside the carrier A, at
the opposite end from the cam 56, and a portion of its surface usually lies in the path
of the rolls at the end of the pin-shaft rock-arms; therefore, at certain intervals in
the revolution of the carrier A, each normally spring-protruded pin 2 will be retracted.
These intervals will vary according as the sheets are of half-width or of full-width, or
as they are collected or uncollected. Therefore, the cain 32 must be shifted to
determine the proper interval; if the sheets are uncollected, the cam will be fixed in
proper position, but if the machine is delivering collected sheets, the cam 32 must,
at alternate revolutions, be brought into a position when it will not retract the pins.
This temporary position is shown in Figure 3ª.
The position of the pin cam 32 is controlled by the position of the triangular
lever 84, and that, in turn, by the segment 28, and the direction of movement of the
pin-cam, caused by a given movement of the slotted triangular lever 84, will depend
upon whether the upper end of the link 83 is attached to one or the otlier angle of
the lever 84.
When sheets of full width uncollected are passing through the delivery, the pin-
cam must be in such a position as to withdraw the pins at the rear of the sheet at
the moment of folding, that is, the position shown in Figure 3. This position is
secured by so placing the parts that a circular hole 87 through the shaft 29 is in line
with a circular hole 86 in the frame, and introducing the locking pin 26 into these
holes. This shifts the position of the segment 28, and consequently of the segment 27;
and the arm 24, which, it will be remembered, is connected rigidly thereto, so as to
raise the cam 6, and hold it permanently in its elevated position. Meanwhile, the
arm 22 with the roll 21 is free to move as the latter engages with the cam path 25,
it being disconnected from the other parts of the machine by the withdrawal of the
pin 26. The movement of the triangular lever 84 into the position shown in
Figure 3, through the link 83 and the arm 82, elevates the cam 32 to the position
shown in that figure, where it remains fixed while the machine is in this
adjustinent.

page_text: When sheets of full width collected are being passed through the machine, the pin
cam will, during the first revolution of the carrier, to wit, that revolution in which no
folding operation occurs, be in the position shown in Figure 34, and during the
second revolution of the carrier, it will be shifted to the position shown in Figure 3,
so as to withdraw the pins from the leading ends of the sheets at the same point as
last above considered.
This position and operation of the parts is effected by withdrawing the locking
pin 26 from the holes 86, 87, and placing it in the position shown in Figure 3^,
locking together thereby the arms 22 and 24. The cain path 25 and cam roller 21
are now brought into action, and during the first revolution of the carrier A,
the roller 21, being in the part of the cam farthest removed from the centre of the
wheel 69, will cause the arm 24 to be in its depressed position, and consequently the
cum 56 to be beneath the path of the bowls 53, 53', so that the latter will pass by it
without engaging therewith. The position of the pin-cam during this revolution of
the carrier A is that shown in Figure 3^.
On the second revolution of the carrier A, the roller 21 is drawn toward the centre
of the wheel 69, and the arm 24 and the cam 56 are elevated into a position such
that the cam 56 will operate upon the bowls of the cross-head of the folding blade.
This movement of the arm 24 carries with it, through the segments 27 and 28, the
triangular lever 84, and depresses the link 83 and arm 82, and raises the pin cam 32
into the position shown in Figure 3, so that, during the second revolution of the
carrier A, the pin-cam will be placed to withdraw the pins at the leading end of
the sheet at the moment of the folding operation.
When it is desired to pass half-width sheets uncollected through the machine, the
pivot of the upper end of the link 83 is moved to the left-hand end of the triangular
lever 84, the locking pin 26 is withdrawn from the position shown in Figure 3, and
again inserted through the holes 86 and 87. The link 83 now draws up lever 82,
and depresses the pin cam to the position shown in Figure 4, in which it causes the
pins to be withdrawn at the proper time from the leading ends of the half sheets. In
this position of the segment 28, the lever 24 will be locked thereby with cam 56 in
its elevated position, when it will throw the folding blades twice in each revolution
of the carrier. The parts remain fixed in this position during this adjustment of the
machine.
When it is desired to adjust the machine in order to pass through it half sheets
collected, the attachment of the lever 83 is left as it is shown in Figure 4, and the
locking pin 26 is withdrawn from its position shown in Figure 4, and again inserted
so as to lock arm 22 to arm 24. The parts will now assume the position shown in
Figure 4 during the first of each two revolutions of the carrier A, and, during the
second of each two revolutions, through the operation of the cain path 25 and the
roll 21 before described, the cam 56 will be raised, and the pin cam 32 depressed to
the position shown in Figure 4, and thus the sheets which are collected during the
first of each pair of revolutions of the carrier A will be discharged during the
second revolution.
The product shown in Figure 37 is obtained by adjusting the press to produce
the product shown in Figure 35, and placing the switch 40 so that this. product is
diverted to a second folder, and there given a transverse fold. In making this product,
the staple-making and setting mechanism may be disconnected, and the sheets
either pasted or folded without attachment to each other, or they may be stapled, as
shown in Figure 38. A product similar to this may also, of course, be made of
thirty two pages by collecting.
The product shown in Figure 39 is obtained by slitting the web into four strips,
as shown in Figures 32 to 34, and passing the two outside strips over diagonal
turning bars, and associating them with the two inner strips. The four associated
strips are then passed through the mechanism set in the position for making a
product of narrow uncollected sheets shown in Figure 4, and the product, as will be
understood from the above description, will be sixteen pages of a length equal to the
width of the strips into which the web is slit, and of a width equal to one-fourth of the

page_text: circumference of the carrier A. A similar product may be made of thirty-two pages
by collecting.

invention, in which modifications are shown.

A
In this machine, the collecting of the sheets in packs is done upon a separate
cylinder carrier, instead of upon the carrier which carries the folding blades.
modified construction for controlling the operation of the stapling mechanism, so as
to cause its action to be intermittent at proper times, is also shown; also a modified
construction for varying the action of the wire-feeding mechanism.
In this machine, also, provision is made for feeding a cover sheet to the collected
pack of sheets, which cover sheet is attached by the staples to the other sheets.
A longitudinal folder for folding or plicating a web or webs by doubling the same
lengthwise, of the ordinary construction of such folders, and similar to that shown
in the figures above described, is part of this machine. Its internal guide or former
is marked L', its external turners or guide rollers 150, 160, and its fold-laying
rollers 170, 180.

page_text: The cylinders or carriers A¹, B', between which the material passes from the
rollers 170, 180, carry several mechanisms. The carrier B is provided with a cutting
blade 102 in the ordinary manner, which blade cooperates with cutting slots 101, 108,
supported by the carrier A¹, which is a common cutting mechanism. The carrier !¹
is provided with means for collecting many sheets thereon, and delivering the
collected pack therefrom, as will be more particularly hereinafter described, and the
carrier A¹ is provided with rotary folding blades 151, 161, that cooperate with folding
rollers 130, 140, to impart transverse folds to the sheets severed by the said cutting
mechanism, and the carrier A' also supports sheet-impaling pins 109, 110, which
hold and carry the forward end of the sheet lengths past the folding devices, and
release the same for such folding operation, as is common in this art.
A carrier C¹, located beneath the carriers A, B, is arranged for cooperation with
carrier A¹. This carrier C is provided with stapling mechanisms, as will hereinafter
he fully described, which cooperate with staple-leg clinching devices supported by
the carrier A', and the products made in this apparatus are finally delivered by means
of a rotary fly consisting, in the main, of curved arms 141, which fly is also a structure
well known in this art.
There is also provided a rotary carrier D', by means of which, and suitable
tapes 181 and conductors 182, a supplemental web is delivered to the carrier B',
to be, united to the body of the product, as 1. cover, as will be hereinafter
explained.
The various mechanisms are geared together so as to be properly moved in the
timely relation necessary, and are hereinafter referred to. Some of this gearing is
necessarily omitted, to render the illustrations perspicuous, but such gearing, part of
which is shown, is as follows:-
The carrier A is provided on its shaft 171 with a wheel 203, that is driven
through an intermediate 206 from the wheel 207 on the driving shaft 250, and the
wheel 203 drives the carrier B1 (see Figure 43) through a wheel 204 on its shaft 172,
and the carrier C through a wheel 205 on its shaft 190.
The rollers 170, 180, are geared together, as is usual, by pinions 188, 189, the
former being driven by an intermediate 202 from a gear wheel 215, that is fast upon
the shaft 171 of carrier A¹, between the frame and the exterior gearing. This
wheel 215 meshes with a gear wheel 187, fast on shaft 172 of the carrier B¹, which
wheel 187 drives the intermediates 103, 104, 105, and pinion 106, which constitute
the train of gearing driving the wire-feeding shaft 122, and this wheel 215 also
drives the gears rotating the folding rollers 130, 140.
When sheet lengths, as two, are collected to form the product to be bound by
stapling, the wire must be fed, and staples formed therefrom and set, only half as
fast as when the cylinder B is not collecting; in the former case, one length of wire
being fed for two revolutions of that cylinder, and in the latter case, one length
of wire being fed for each revolution of that cylinder.
Of course the wire feed and staple-inaking and setting, when three or more sheets
are collected, will require this action to be changed to suit the period at which the
united pack is delivered to be stapled, but from the arrangement of mechanisms
for the stapling of two sheets, will be understood the modified action for a
greater number of collected sheets.
There are two stapling mechanisms supported in the carrier C¹ (see Figure 48),
which, being duplicates, both may be understood from a description of one, like
letters of reference applying to both. One stapling mechanism will now be de-
scribed (see Figures 46, 49, 60, 61, 62). The staple-bending arms 111, 112 project
from a guide or plunger 131, and stand a distance apart equal to the length of the
crown of the staple. This guide or plunger 131 has a round body, adapting it to be
entered into and guided in a circular socket formed for it in the carrier C, in which
it is seated upon a spiral spring 132, and normally pressed outwardly. Its position
therein is maintained by means of a closing cap 195, having an extension 196 that
fits within an enlarged recess in the cylinder, so that its lower end will afford a
limiting stop for the upward thrust of the guide or plunger carrying said arms, and

page_text: this closing cap 195 also carries a setting bed 113, which is a piece fitted in a squared
central socket in the closing cap 195, wherein it is centrally held by set screws, as
shown in Figure 61.
The face of the cap 195 coincides with the periphery of the carrier C¹, being
curved to conform thereto, and the sides of its socket constitute, with the outer sides
of the setting bed 113, guide-ways 133, 134 (see Figure 61), for the bending
arms 111, 112. The withdrawal movement of the bending arms 111, 112, is
controlled by means of a compound rock-arin, the adjustable member 152 of which
is secured to the fixed member 155, which is fast on rock shaft 153, said member 152
being hung on a pivot 154 projecting from the member 155, the said member 152
having branches to embrace the shaft 153, and its branches being provided with
adjusting set screws, to fix the position of the member 152 on the pivot 154, and
thus recure the relation of the compound arm to the shaft 153 (see Figure 46). The
operating end 114 of this compound rock-arm plays in an elongated slot formed in a
shank 107 projecting from one side of the plunger 131, which carries the bending
arms (see Figure 47). This slot admits of free action, at times, of the springs 132
upon said plunger, and admits of the withdrawing action being accomplished slowly
by a long cam 192, of easy pitch. This rock shaft 153 is normally so held by
means of the spring-seated rod 156, as to allow the plunger 131, and the bending
arms it carries, to be pressed outwardly to the full extent of the operation of their
sustaining & actuating spring 132, and the limitation by the stop 196. The rock
shaft 153 is rocked, against the pressure of its spring rod 156, by means of a
rock arm 157 at one end of the carrier C, which rock arm 157 is provided with a
friction roll 158, that is in contact with, and rides upon, the periphery of the
cam 192, and at times on the cam segment 191.
The staple-bending arms 111, 112, are provided, in their inner faces, with
longitudinal grooves that coincide in position with the wire groove across said
bed 113 and the arm 112. This arm 112 (see Figure 46) is cut away on its outer
side to form a recess (see Figure 62), to enable it to pass by the wire cutter 120, and
is provided with a steel tappet 121, projecting into said recess, to vibrate said cutter
in severing a wire length, as will be presently explained. The bending arms 111, 112,
when protruded, embrace and sweep over a curve-forming anvil 162, which anvil
and accessories may be of any suitable construction, but the construction illustrated
will be explained herein, in the course of the description of the operation of the
mechanisms.
There is provided a wire cutter 120 which (see Figure 50) is pivotted so that it
may be vibrated against the face of the wire guide 164, and across the pathway of the
wire through said guide. It consists of two arms, one constituting the cutting blade,
and the other acting as a bearer to correctly position the blade, said bearer being
seated upon a spring 137, constantly pressing it against stop 138, which devices thus
normally hold the edge of the cutting blade close to the pathway of the wire.
This cutting blade carries a cat projection 119, which normally projects into the
pathway of the tappet 121, carried on one side of the bending arm 112 (see Figure 46),
where the result of the contact of this tappet arm (in its rotary course of travel)
with the projection 119, is to quickly vibrate the cutting blade 120, and sever the
wire length protruded across the face of the anvil 162, while the same is lying in the
seat 118 of said anvil, thus resting against an abutment which, coacting with
the slightly projecting faces of the arms 111, 112, constitutes with them a means of
nipping the wire, and holding the same while it is being severed into a staple
length.
The auvils 162 are fastened to a bracket 240 secured to the framework, and they are
adjusted so that their curved underfaces shall be concentric with the periphery of the
carrier at their forward positions, and so that their rear portions shall be excentric
thereto. The width of the anvils is equal to the inside length of the crown portions
of the staples; the rear portion is provided with the wire seat 118; and the forward
portion has the recessed sides and the leg-bending blades 144, 145.

page_text: As here shown, however, the abutment 118 is fixed, and the inward movement of
the arms 111, 112, against the spring tension, is depended on for freeing the staple-
length of the wire from the abutment 118, the wire engaging face of the abutment
being bevilled or sloping (as shown best in Figure 46), so that while serving to hold
the wire securely for severing, yet, as the arms 111, 112, move onward, the wire will
ride beneath the abutment; moving the arms slightly inward, and then being
advanced by the arms beneath the anvil.
The mechanisms for controlling the stapling action, where two sheets is the
number collected, will now be explained.
A cam 192, which is shaped to so rock the staple-bending arm shaft as to allow
said arms to protrude at each revolution of their carrier, is fixed by means of a sleeve
encircling the shaft 190 of carrier C¹, and secured to the framework.
A cam
seginent carrying wheel 201 is loosely mounted on this sleeve (see Figures 48, 59),
said wheel being driven from a wheel 213 on the main driving shaft 250 (see
Figure 40), at half the speed of carrier C¹, or appropriate speed, through inter-
mediates 212, and a companion 222 of like size on the same stud, but inside the frame,
and engaging a wheel 210 on the shaft 211 of the rotary fly, said wheel 210 driving
intermediates 209, 208, the latter being geared with the wheel 201, which is within
the side frame, and carries, upon its inner face, said cam segment 191 (see Figures
47, 52 to 58), which segment is flanged to coincide with the high part of the fixed
cam 192.
As the example being described is the stapling of two sheets, it will be understood
that the proportions of the gearing driving the carrier C, and the cam carrying
wheel 201, are such as to impart to the latter, half the speed of the former; that is,
although the wheel 201, driven by the wheel 213, and the wheel 205, driven by the
wheel 207, are of the same size, the wheel 205 is but half the size of its driver, and
hence the wheel 205 will make two turns to one of the wheel 201. The stationary
cam 192 rocks the arm 158 of the shaft 153, so that the low part of that cam allows
the spring 156 to protrude the staple-bending arms for action during each revolution
of their carriers, the high part of that cam, when acting, holding said arms, within
the carrier.
When, however, the carrying wheel 201 rotates, the cam segment is so moved as
to prolong the high part of the cam 192 during each alternate revolution, so as to
prevent said bending arms from being protruded during the whole of each alternate
revolution of the carrier C¹.
These devices thus operate to hold the staple-bending arms within the carrier C¹
during one revolution, and permit them to be protruded and operate through the
cutter-actuator, to sever the wire length, and, by their own action, in connection with
the staple-forming anvil, to convert said length into a staple, carry said staple to the
setting point, and, in connection with the die, to clinch its legs, all at the proper
times, or during the second revolution of the carrier C. This wheel 201 (see
Figure 58), carrying cam segment 191, is arranged to be locked stationary in such a
relation to the fixed cam 192 as to coincide with the high part of that cam, and thus
be inactive when the staple arms are to operate at each revolution.
The locking of this wheel and cam seginent is accomplished by taking off the half-
speed wheel 208, shown in position in Figures 43 and 45, and mounting on the same
stud 136 a stop piece, one arm, 193, of which is forked, so as to embrace a stud 116
on said wheel 201, while another arm, 194, projecting from the same hub, has a
locking pin 117 securing it to the framework, said wheel being thus secured motion-
less, and its cam segment in correspondence with the cam 192, or, in other words,
inoperative (see Figures 58, 59).
The arrangement of mechanisms for feeding the wire at a uniform length (the
cylinder C¹ making either one or two revolutions) is as follows:-
The shaft 122 of the wire-feeding mechanism, the rotation of which is controlled
by the train of gears 103, 104. 105, and 106, is provided with worms 125, that
engage worm wheels 126, that drive the upper members 128 of the wire feeding discs
128, 129, the lower member 129 being moved by means of spur wheels a¹, e¹, which
C

gear their shafts together the nip or bite of the two being controlled by means of an
adjusting screw 159, that, turning in a bearing plate 160, has its stem engaging in
the screw-threaded opening in the shank of the roller socket or bearing, the adjusted
position reached being maintained by a set screw 179.
The end of the worm shaft 122 is provided, outside the frame, with two wheels 106,
105, whose relation is as two is to one (it might be a different proportion, according
to the number of sheets associated), which wheels are driven through intermediates
104, 103, from the wheel 187 on the shaft of carrier B¹. The intermediate 103
is a wide-faced wheel, and on its stud is loosely pivotted an arm 123, in which
is mounted the intermediate wheel 104. This wheel 104 may be geared with the
wheel 106, when it is desired to feed the wire at one speed, and with the wheel 105,
when it is desired to feed it at half that speed, as follows:-
By slacking the T-bolt 124, the arm 123 may be lifted, and slid along on the stud
of the wheel 103, and the intermediate wheel 104 brought in gear with the larger
wheel 106 on the worm shaft 122. A lug is provided on the frame to suit the
different positions of arm and T-bolt. The end of the arm, where it engages with
the T-bolt, is cut away, so that the arm may be raised and sustained in two
positions, and thus enable the wire feed to be operated at the appropriate
speed.
The wire is led from a reel 225, and is passed through the guides 163, 164, which
are on opposite sides of the feeding discs 128, 129, and act to direct the wire
accurately across the face of the forming auvil 162, the extended portion, or leading
end, of said wire being thus accurately directed into a wire groove or seat 118, with
which the anvil 162 is provided, (see Figures 46 and 51), the same being formed as
a transverse abutment in a removable steel piece 127, attached to the heel of said
anvil.
1. The collecting cylinder B¹ is provided with the usual sheet-impaling pins for
controlling the leading ends of the sheets, so as to cause appropriate ones to be carried
around upon its surface, and make the transit of its circular path, and causing each
succeeding sheet to lap upon the preceding one thereby performing the operation
known as "collecting."
In the collection, say; of two sheet-lengths, it is obvious that these pins must be
'protroduded at the point where the cylinders A¹, B¹, run nearest together, in order to
take a sheet at one revolution, and be withdrawn at the same point at the succeeding
revolution, in order that the collected sheets may pass onward upon the surface
of the cylinder A¹, to be advanced for delivery, or be delivered to the pins of cylinder A¹
'for that purpose.
In order to accomplish this, said cylinder B¹is provided with a pin-operating cam 142,
'that runs loosely upon the shaft 172 of said cylinder, which pin cam has fastened to
its outer side, by spline x¹, a gear wheel 175. Motion is communicated to said pin
cain gear wheel 175 by means of a pinion 173 fastened by spline w¹ on its shaft 172,
through idlers 174, 176, which are fastened together, and revolve upon a stud that is
secured in the side frame.
The size of the pinion 173 and wheel 175, that of the intermediate gears 174, 176,
and the relative proportions of said gearing, is such, that, when the cam is rotated by
this gearing, it makes one revolution to two of the cylinder B¹, and thus presents its
operating portion to the rock arm, that moves the shaft of the impaling pins,
at such times as to protrude the pins at one revolution and withdraw them at the
next.
When it is desired to withdraw the pins of the collecting cylinder, so that they
shall not engage a sheet, and carry it around the cylinder B', the pin cam 142, being
'revolved to the point where it holds the pins within the cylinder, is fixed in place by
a sliding locking pin 143, which enters a socket for it in the cam, and the stud
carrying the wheels 174 and pinion 176, which has a bearing in the side frame
eccentric with it, is rocked so as to hold said gears out of engagement with their
companion gears on the shaft of cylinder B¹. This stud holds the wheels in gear by

page_text: means of an arm 183 fast to the stud, and supported by means of a locking screw 135
that takes into the side frame (see Figure 42).
When this arm 183 is turned into a position the reverse of that shown in Figure 40,
and maintained by the screw 135 entering the hole 184 in the side frame, the said
wheels will be thrown out of gear, as in Figure 63. When the pins are not in
operation, the sheets will pass in succession to the stapling mechanisms, and when
in action, collection of them will take place, and packs of sheets will be delivered to
the stapling mechanisms.
Means are provided for introducing a cover sheet.
As shown, it consists of
tapes 148, 181, which are fast tapes, having the surface speed of the carriers B¹, D',
and they form a conducting pathway between cutting cylinders 149, 199, and the
carrier D', and its breaking rollers 197. The tapes 148 return around pulleys near
the carrier D, and the tapes 181 extend into contact with the surface of the
carrier D', and return around pulleys 185 and stretching pulleys 186.
The pathway for the cover sheet is constituted, in part, by said tapes, and is
extended close to the carrier B¹ by means of conductors 182, of the usual construction.
The pathway constituted by the tapes 148, 181, and conductors 182, may convey
a coloured or unprinted web, that is perforated transversely at distances a sheet-length
apart, the same being fed at half speed, but preferably, as more practical, a cover in
the form of a supplement web, printed by a supplemental printing mechanism, is led
through cutting cylinders, as 149, 199, which run at half the surface speed of the
cylinders B, D, said cutting cylinders operating to so perforate the web transversely
at points the length of a sheet apart, the leading section of which, when nipped
between the breaking rollers 197 and the carrier D', will take up their more rapid
speed, and be fed onward thereby, one section being broken asunder from the web on
the perforated line.
The delivery tapes, which cooperate with the rotary fly, receive their motion through
a worm 216 on the fly shaft 211 and worm wheel 217, which is on a vertical shaft
carrying at its lower end a bevil wheel 218, that meshes with a bevil wheel 219 on
the shaft of the tape-pulleys 220.
The paper arrives at this delivery apparatus in web form; it may be folded if it has
passed over a longitudinal folder, as 11, and, if slit on its central line, as is a cominon
practice, it will be two associated webs.
The web or webs pass between the carriers A, B1, the cutting devices whereof sever
the saine transversely into sheet lengths which may be collected together by means
of the described devices, or other appropriate ones, causing the cylinder B¹ to operate
as a collecting cylinder. The sheets are carried onward by means of the pins of
carrier A¹, and ultimately are folded off from said carrier by its folding blades and
folding rollers in the usual way. These sheets, as they pass the carrier C³, receive a
line of staples set on the line of folding. If this staple-bound product is to be provided
with a cover, the same is brought to cylinder D1 by the tapes 148, 181, and delivered
to the pins of the cylinder B₁, being carried around it at full speed and laid thereon,
so as to underlie the sheets received from the main apparatus, so that it will come on
the outside of the collected pack of sheets, when the same is transferred to cylinder A¹,
and carried to the stapling mechanisms.
In order to show the various operations of which this apparatus is capable, we will
first describe the simplest operation it may have, and that is, uniting two webs
together, which may be the folded product of the longitudinal folder L', whether
that product be united by a single fold at the head, or be divided at its head by a
slitting device operating in the usual way. In both cases, it will present two webs
passing between the carriers A¹, B¹.
In this arrangement, the pins of the collecting cylinder B₁ will be held out of
action by separating the wheels 174, 176, from their companion wheels 173, 175, as
in Figure 63. The wheel 201 will be locked stationary, so as to hold its cam
segment in a position corresponding with the fixed cam 192, by means of the
arms 193, 194, as in Figure 59.
Thus arranged, the collecting cylinder B will cease to operate as such, and the

page_text: stapling mechanisms in carrier C¹ will be active at each revolution thereof, the result
of which will be that each pair of associated sheets, in passing between the carrier C¹,
supporting the staple-bending and presenting tools, and the carrier A¹, which is
provided with the setting die in the usual manner, as known in the art, be stapled
widthwise upon its ultimate binding line, upon which said sheets will be folded by
the action of the folding blades of carrier A¹, by being tucked into, and passing
through, the folding rollers 130, 140, which staple-folded sheet descending into the
rotating fly, will be laid upon the tapes 221, and delivered.
If it is desired to add to said two sheets a cover sheet, and staple the whole
together, this may be done by throwing the cutting cylinders 149, 199 out of action,
and leading the cover, in the form of a continuous web, into the control of the
carriers A, B1, whereupon the three associated sheets will be manipulated, as has been
described with respect to the two. In order, however, to attain the greatest
practical usefulness of a machine of this character, the collecting cylinder B₁ will be
thrown into operation, its collecting devices being, as has heretofore been intimated,
capacitated to collect two or more sheets (which is but a modification of the
apparatus shown and described), its collecting devices being set into operation as
follows:-
The sheet-impaling carrying pins belonging to said cylinder will be made to
operate appropriately for the collection of two sheets from the main source of supply,
by uncoupling its cam 142 from the cylinder, and throwing the wheels 174, 176, into
operative position, as shown in Figure 44, whereupon said cylinder will carry the first
sheet coming within the range of action of its pins, around the cylinder, to be over-
lapped by the succeeding sheet length, and withdrawn appropriately, to allow the
associated pair to be moved onward for delivery.
The stapling mechanisms are set into operation so as to staple the successive
collected packs of sheets brought within the range of its action, by adjusting the
wheel 208 into its active relation with the train which drives the cam segment
carrying wheel 201, as in Figure 45, whereupon the cam 192 will, at every second
revolution of the carrier C¹, have that cam elongated by the cam segment 191 at the
proper periods of time during the rotation of its carrying wheel 201, as in Figures 53
to 57, so as to hold the staple-bending arms within the cylinder at each repeated
revolution thereof, said stapling mechanisms, therefore, being operative only
at such periods of time as a pack of collected sheets is brought within their
range of action.
To add to the number of sheets collected, and especially add a sheet of differing
characteristics, as colour or quality, from the main pack of sheets, the half speed
cover introducing mechanism described is brought into action to deliver such cover
sheet to the cylinder B¹ beneath the pack of sheets from the main apparatus, where-
upon the mechanisms adjusted as last described, will so operate upon the collected
pack of three sheets, as to staple the same together, and deliver the stapled product
in book-like form. In all of these operations described, the train of gears 103, 104,
105, 106, will be appropriately adjusted to supply the wire to the stapling mechanisms,
according as the same are making one or two sets of staples.
A third machine embodying modifications of this invention is illustrated in

The machine shown in these figures shows chiefly modifications in the mechanism
for forming and inserting the staples.
The delivery apparatus shown, in which the present improvements are embodied,
consists, in a general sense, of a longitudinal folder L2, external turners 400, 401, and
fold-laying rollers 402, 403. Its delivery cylinders, C2, D2, are provided respectively
with cutting knives a² ², and cutting sheets 22, 02; the cylinder D2 being additionally
provided with double rotating folding-blades 351, 352, that cöact with folding
rollers 353, 354, and the folding rollers 353, 354, have a sheet pathway extending
therefrom to a roller 355, which pathway consists of a conductor 356, and sets of
tapes 357 running from pulleys 358 over the roller 355, tightening pulleys 362, and
returning over a roller 363 to the pulleys 358. Arranged beneath the discharging
end of said pathway, there is a sheet-delivery embodying a rotating fly that consists

page_text: of curved arms 359, and which, aided by a cooperating guard 360, lays the folded
sheets upon sets of discharging tapes 361, that run over pulleys 364, 365, and suitable
intermediates.
The cylinders C2 D2 are mounted to revolve in journal bearings provided in the
framework, and their shafts are geared together so as to revolve them in unison, by
means of toothed wheels, only one, 434, for carrier C2, of which is shown, and said
cylinders are driven through a wheel 407 on the shaft of the cylinder C², which gears
with a wheel 408 fast on a shaft 413, which carries a wheel 409, outside the frame, which
will be connected with its driver, as through wheels 410, 439, with a driven shaft of
the printing machine. The fold-laying rollers 402, 403, are geared together by
pinions at one end, to which motion is imparted by an intermediate 421, meshing
with a toothed wheel on the end of cylinder D2, which wheel is not shown, but is a
companion to 434, which is upon the shaft of carrier C². The rotating folding
blades 351, 352 are maintained in their normal or inoperative positions by means of
a curved guard 411, and are caused to make semi-rotations, when projected into and
withdrawn from the folding rollers 353, 354, by any of the means now common in
this art.
The folding rollers 353, 354, are geared together by pinions 423, 424,-the pinion
423 on the roller 353 meshing with the toothed wheel on the cylinder D³. The
cutting knives a², c², carried by the cylinder D2, which may be of any construction,
are supported in holders that are inserted in sockets, as 412, and the cutting slots i², o²,
are similarly constructed and mounted in the cylinder C². The rotary Ĥy 359 and
discharging tapes 361 are driven from the shaft 413 by means of wheels 419, 418,
communicating rotary motion to the fly-shaft 420, which latter carries, near one end,
a worm 366, that engages a worm wheel, 367, on one end of a vertical shaft, which,
at its other end, carries a bevel gear 368, engaging a similar bevel gear 369 on the
shaft of the tape pulleys 364. This pulley shaft is also provided with a cam disk 428,
upon which bears a rock arm 429, held to duty by a spring arm 425, by which
devices, after a suitable number of revolutions of the fly, the shaft 426 is rocked
slightly, to thrust the pusher bar 427 forward, and cause it to throw outward the
folded sheet then being delivered, so that its projected relation to the rest of the
sheets may indicate the number that has been delivered or piled on the tapes 361.
Such a delivery mechanism operates as follows:-One or any number of webs of
paper W, E, B, S, received from one or any number of printing machines, in passing
through the longitudinal folding mechanism, will be plicated by longitudinal folding,
and this plicated product, upon emerging from the fold-laying rollers 402, 403, and
being guided and conveyed to and between the carriers C2, D2, will be severed into
sheet lengths, and such sheet lengths will be doubled or folded into the nip of folding
rollers 353, 354, by one of the rotating folding blades 351, 352, and these folded
sheets, in emerging from said folding rollers, will enter the sheet-conducting pathway,
and, passing over the roller 355, descend vertically therefrom, and, directed by the
guides 360, enter into one of the sets of curved arms 359 of the rotary fly, and be
laid down thereby flat upon the tapes 361, which, moving outwardly, will ultimately
deliver said folded pack.
In order that the sheets composing said folded pack may be bound together to
constitute a book-like product, this delivery is provided with stapling mechanisms,
whereby, from separate wire lengths, two staples are made, and not only inserted
through the plies composing said product, on the binding or last folding line thereof,
but said staples have their projecting legs bent down or clinched upon said plies, so
that when the product is folded, its binding staples present their crowns on the
outside, and their clinched legs upon the inside of said product.
The wire-feeding and cutting mechanism, and the staple-bending, presenting, and
setting mechanisms are associated with the cylinder C2, while the staple-leg clinching
devices are carried by the cylinder D².
As two staples are simultaneously made, inserted, and set, and the various
mechanisms therefor are duplicates, a description of one set will apply to both, and

page_text: either will be readily understood from this description, since like reference characters
distinguish like parts in each mechanisın.
The fine mild steel wire 320, from which the staples are to be made, is fed
inwardly, parallel with the cylinder face, toward the bending mechanisms, from
spools 430, mounted to turn on spindles journalled in brackets carried by the frames,
being directed through a guide slot 321 (see Figure 67) passing between feeding
wheels 322, 323, (see Figures 67, 72, and 73), and thence through a guide slot 324
in a block that supports the wire close up to the point of severance.
Each wire feeding mechanism is mounted in a head H2, by which the same are
adjustably secured to the cross bar 431 by means of holding screws 437, 438, which
heads sustain the journals [2 for the shaft 432. Each feeding mechanisın consists of
two grooved feeding-wheels 322, 323, carried by spindles that turn in bearings in
said bead, which spindles carry wheels 325, 326, (see Figure 73), gearing thei
together for uniform movement, the spindle of the wheel 323 being extended to
support a worm-wheel 327, which is engaged by a worm 328 that is splined on the
worm shaft 432. This worm shaft is journalled in and supported by the heads which
carry the feeding disks, and is rotated by means of a pinion 445 at one end, which
meshes with one (444) of a train of intermediate gears, 442, 443, 444, connecting it
in gear with a wheel 434 fast on the shaft of the cylinder C2, which worm shaft 432
is elongated at the end bearing this pinion 445, so that the latter may slide thereon,
and thus be removed into and out of mesh with its driver, the gear wheel 444, and
so cause or stop the movement of the wire-feeding wheels 322, 323,-in carrying out
which operations, said pinion slides on a spline 36.9, with which the worm shaft 432 is
provided, and to maintain this pinion in either position of its adjustment, it carries a
grooved collar 399, into which projects the yoked end of a retaining arm 398 (see
Figure 69), a right-angular branch (397) of which plays against the face of the cross-
bar 431, and has an adjusting slot through which passes a set screw 396, by which
its desired position is secured. By these means, the feeding of the wire may be
stopped, and the production of staples be suspended at any desired time, as, for
instance, in slowly operating the printing machine, in making ready. For the
purpose of testing the stapling devices, in adjusting them, this worm shaft 432 is
provided with a hand-wheel 435 at one end, by which the wire feed may be operated,
without running it from, and at the speed of, other parts.
When a staple length of wire is advanced by the feeding wheels 322, 323, it is
protruded beyond the mouth end of the slot of the guide 324, and requires to be
detached from its body portion, in order to be free, so as to be convertible into a
staple. To perform this detaching or severing operation, a movable cutting blade 308
is so pivoted to the feed roller head, as to be capable of sweeping past, and in shear-
ing relation to, the mouth or delivery end of the wire slot of the guide 324, and this
blade 308 has a tail piece 307, which bears, in one direction, upon a stop 302, and is
borne upon by a spring 318, to normally hold it in contact with said stop 302, and
when thus normally held in place, the shearing edge of the cutter 308 will be close
to, but not in the pathway of, the wire, although it may cross the same. The
vibratory movement of this cutter, to sever the wire, is caused by contact therewith
of the staple bending tool, brought about periodically as said tool, in its rotative path
of travel, sweeps past the point occupied by the wire, which operation will presently
be more particularly explained.
The movable stapling tools are supported in the cylinder C2, by which they are
carried in a rotative path of travel, operating first to cause a wire length to be
detached; then, while carrying the same onward, cooperating with a curved forming
anvil that is fixed over the cylinder, to convert said wire length into a staple; then
to force the staple legs through the material passed between the cylinders C², D2;
and finally, in conjunction with a die carried by the cylinder D², operating to bend
or clinch the staple legs down onto the said material.
As herein illustrated, there are two sets of stapling tools arranged lengthwise of
the cylinder C2, and, by reason of its being equal circumferentially to the size of two
products, the stapling tools are duplicated at opposite points of the cylinder. All

page_text: being alike, a description of one will apply to all, and like characters of reference are,
therefore, placed upon like parts, that this description may be read in connection
with either of the stapling mechanisms.
In each set, there are two stapling tools, the staple-bending arms, and staple-
setting tool or driver between them, and they are supported in a circular socket 436
cast with the cylinder C2 (see Figures 67, 68, 70, and 74), and having a closing
cap 390, with winged sides, to provide for the reception of securing screws 392 (see
Figures 69 and 70).
The staple-bending tool has two side arms, 329, 330, which constitute what is
sometimes called a staple-bending fork, which arms are parallel, and separated a
suitable distance to admit of the play between them of the setting tool or driver 332.
The rearward portions of these arins 329, 330, of the staple bending tool, which are
guided in a rectangular opening through the closing cap 390, are extended to provide
it with shoulders m² m², which project a distance about equal to the diameter of the
wire operated on, the front faces of which shoulders are aligned or coincide with the
rear face of that portion of the driver which is the actual setting bed,--in this example,
the plate 340. The arms 329, 330 are provided with steel wearing pieces 310, 311,
in their inner faces, in which are cut staple-leg guiding channels 301, 306 (see
Figures 74 to 77, inclusive), in which the laterally projecting edges of the plate 340
or setting bed are guided in the reciprocation of the driver.
These arms 329, 330, project from a circular base 331, which slides in guiding
contact with the circular inner wall of the socket 436, at the same time acting as a
stop, in connection with the inner end of the cap 390, to limit the outward protrusion
of the arms 329, 330, said staple-bending tool being constantly pressed outward by
means of a coiled spring 333 within the socket 436. If a more perfect or longer
guiding bearing for the staple-former is desired, it may be provided with a hollow
shank or guide 334, projecting inwardly from its base 331, within which its spring 333
will be held (see Figure 70).
The driver 332 has a rectangular body, by which, in its longitudinal movements, it
is guided in a similar shaped opening provided between the arms, 329, 330, and the
walls of the cap 390. It has a central stem 335 projecting inwardly, and guided at
its free end in a circular hole cut through the bottom of the socket 436. This
driver 332 is constantly pressed outwardly by means of a coiled spring 336 encircling
its stem 335, and bearing upon a collar at the upper end of the stem and the inner
face of the bottom of the socket 436, its longitudinal movement with respect to the
arms of the staple-bending tool being limited by a transverse stop bar 337, carried by
the arms of the bending tool, against which a shoulder 338 on the driver bears (see
Figure 79).
The working face or actual setting bed of the driver 332 is a hardened steel
plate 340, let into a block or holder 371, that is supported in a socket cut into the
outer end of the driver. This setting bed or plate 340 is of a thickness equal to,
it may be slightly in excess of, the diameter of the wire operated upon, and its working
face, which is the actual setting bed, should be flush with the front portion of the
end face of its holder. The rearward portion of the end face of the setting bed
holder, or that part of it which lies immediately behind the setting bed, projects
beyond the setting bed, or plate, 340, to a distance about equal to the diameter of
the wire from which the staple is to be formed, so as to constitute an abutment 339,
which conforms, or may conform, with the height of the shoulders m², n², of the
staple-bending arms. The sides of this plate 340 project laterally (see Figure 80)
to a distance equal to, or slightly greater than, the diameter of the wire, and play in
the staple-leg guiding channels 301, 306 (see Figure 78), cut in the inner faces of
steel plates 310, 311, with which the arms 329, 330, of the staple-bending tool
are provided.
The shoulders m² m² of the bending arms 329, 330, and extended abutment 339
of the driver, are, at the time of cutting the wire, and during its incipient forward
movement, aligned, and constitute a wire-supporting abutment, and they are here-
inafter collectively and singly referred to as such; but it will be understood that the

page_text: inward movement of the driver at times separates them. By constructing the
abutinent 339 of the driver so that it projects slightly less in extent than the diameter
of the wire operated upon, and by making the wire grooves 301, 306, of like relation
to the wire operated upon, the great advantage will he had, of compelling each
wire-length, converted into a staple, to take up all of the wear occasioned by that
operation, thus transferring such wear upon the face of the setting tool and its
driver, to the wire length during its conversion into a staple, which is performed
while the bending arms and driver sweep the wire length over the forming anvil;
and, as the wire is of softer material than said anvil, it takes the wear instead of
said anvil, with the face and sides of which it is in contact while being so swept
forward, and having its ends upturned to form legs.
The longitudinal movement of the stapling tools in carrier C2, is in part controlled
through a rock arm 341, that protrudes through an opening 316 in one side of the
socket 436, and engages in an elongated bearing slot 303, with which the shank
or guide 334 of the staple-bender is provided, this shank or guide being preferably
provided with a plate 343, to furnish a broader bearing for said arm 341. When
the cylindrical shank 334 is omitted, as in Figures 74 and 75, the plate 343 having
a bearing slot 303, may be secured to the base 331 of the bending tool.
This rock arm 341 projects from a rock shaft 372, that is journalled in the cylinder
heads, and is rocked by means of a rock arm, 373, fast to said shaft, and having an
antifriction roll 374, that bears against the inside surface of a cam, 375, fixed near
one end of the cylinder C², and the rock arm 373, and with it the arm 341, is
constantly pressed outwardly, so as to cause its roll 374 to properly contact with the
cam 375, by means of a spring rod 376, that moves in guides attached to the
cylinder head, and is connected to the shaft 372 by a rock arm 377.
It is to be observed that although the staple-forming anvil, and the parts it carries,
may be so related in their assemblage, as to properly coact with the staple-bending
and setting tools, wire cutting devices, and clinching die, it becomes necessary, in
consequence of the small size of the wire used in this inachine, and the high speed at
which said machine must be run, in practice, that the tools which support the wire
while being severed into a staple-length, and which carry said staple-length onward,
in the operation of forming it into a staple, by bending its ends into legs, and set the
same in the material, shall be provided with means for fine adjustment and accurate
performance.
One way of accomplishing this is illustrated herein (see Figure 68), and it consists
in controlling the action of the rock arm 341, whereby the movements of the stapling
mechanisms are at times governed, and this is accomplished by providing the rock
shaft 372 with an adjusting stop, consisting of a toe 370, fixedly projecting from said
shaft, and arranged to extend between arms 378, 379, which constitute rearwardly-
extended portions of the rock arm 341, that carry, respectively, adjusting
screws 381, 382, whereby the position of the rock arm 341, relative to its actuating
rock arm 373, may be adjusted, and the position of its operating end in the slot 303
of the shank or guide 334 of the staple-bending arm, be determined.
As the setting tool follows the outward movement of the bending arms, their co-
relation being fixed by the bar 337, and the outward protrusion of both being limited
by the base 331 engaging the cap 390, it will be understood that, when both are
fully protruded, as in Figure 74, these tools are properly positioned for co-action with
the means for cutting the wire, and for performing the operation of converting the
detached wire length into a staple, as they move onward over the anvil 350, and
reach the position shown in Figure 68, during which onward movement the setting
tool is moved inward.
This inward movement of the setting tool or driver 332, in its transit from the
position it has in Figure 74, to the position attained in Figure 68, is caused by the
eccentric portion of the face of the anvil 350 acting against the pressure of
the spring 336, while inward movement ceases when the concentric portion of the
anvil face is reached, as in Figure 68. At this time, the detached wire-length will
have had its end bent against the sides of the anvil, and at right angles to its crown,
D

page_text: thus constituting it a staple, the crown of which rests against the driver 332, or
setting bed 340 thereof, while its legs are supported in the guiding channels 301 and
306 of the staple-bending arms 329 and 330.
In former constructions of rotative stapling mechanisms, the withdrawal of the
bending arms from the staple legs, while the staple is maintained stationary by rest-
ing upon the driver, or setting bed thereof, has been accomplished by contact of said
arms with the carrier bearing the setting die, whereby the said arms are pressed
inwardly against the resistance of their supporting springs, as the staple legs are
entered into the setting die and clinched. Practically, it is found to be detrimental
to permit the blow to be made which results from that mode of operation, and which
is occasioned by the sudden contact of said arms with the face of said carrier, and
hence the new mode of operation, provided by the means heretofore described, for
positively withdrawing said arms through the rock arm 341 has been adopted.
It will now be understood that from or about the time that the limit of the inward
movement of the setting bed has been reached, and the staple is completed, as in
Figure 68, that the bending arms 329, 330, as they approach and pass the clinching
die in the carrier D2, must be withdrawn. This is gradually accomplished by means
of the rock arm 341, which moves inoperatively from its position midway of the
slot 303, into operative contact with the lower face of the said slot 303, while the
stapling tools move from the position of Figure 74 to that of Figure 68, during which
movement the staple is completely formed, and then begins its action, whereby the
arms 329, 330, then carrying a formed staple onward, are withdrawn, while the same
are approaching the clinching die, the operation being such, that the withdrawing
action of said bending arms will first slowly proceed, as the major part of the
transit towards the setting point is made, and result in exposing the staple legs.
or causing them to protrude from the said arms, in position, but still supported
thereby, to impale the material to be stapled, and enter into the setting die.
This stripping movement gradually proceeds until the arms, and staple carried
thereby, are closely approaching the setting point, whereupon the roll 374 of the
rock arm 373 will encounter the part 313 of the cam 375, and thus quickly
complete the withdrawing action of these arms, at which moment the setting of
the staple legs is accomplished by coaction with the clinching die. The reverse
movement of the rock arm 373, and consequently that of the arm 341, at once
begins, and the outward protrusion of the arms 329, 330, the arm 341 then
passing the centre, and gradually allowing the springs to act to protrude said
tools, until they are seated, thus avoiding the blow which the springs uncontrolled
would occasion, and said arm still moving, reaches a point in said slot in which
it does not bear again until another withdrawal is to take place, thus allowing an
elongated cam 375, or one producing an easy movement, to be employed.
The stationary curved forming-anvils 350 are fastened to the framework, to
overhang the cylinder C, being longitudinally so located with respect to that
cylinder, as to coincide with the rotary paths of travel of the stapling tools,
and properly cooperate therewith. In a general sense, the underface of this anvil
is coincident with the periphery of the cylinder C2, but its rear end is curved
eccentrically so as to form such a wedge-like entrance end for the passage of the wire
length over it, as to accomplish the formation of the staple, as will hereinafter
appear.
At its said rear end, this anvil has a detachable piece 383, that is provided on its
face with a central projection 384, which diminishes in a forward direction until it
vanishes; and becomes coincident with the general face of the anvil 350. It is of a
width suitable to be engaged by the central portion or crown of the staple-length of
wire, and the projecting end of the driver 332 has a slight central recess 312, to
enable it to pass over the projection or rib 384, as is seen in Figure 87.
This piece 383 of the anvil 350 is recessed rearwardly of the projection or rib 384,
to receive a projecting abutment 385 which is of a width equal to that of the
projection 384, and of a slight length. It has a considerable body portion, by which
it is pivoted in this recess, and its forward end normally rests against the wall of the

page_text: mortise, as in Figure 88, where it is held thus seated by a leaf-spring 386. The
abutment proper, or projecting part 385, has an angular face which normally projects
a little below that of the projection or rib 384, as in Figure 88.
The rear end of the abutment 385 constitutes the receiving and supporting surface
for the wire while being fed into position for cutting, and while being cut by the
cutting blade 308, at which time the projecting abutment 339 of the staple driver or
setting tool, and the shoulders m², n² of the bending arms 329, 330, constitute an
abutment which contacts with the wire, and holds it while being severed and moved
onward. As the bending arms and setting tool, both protruded to their full extent,
as in Figure 74, approach the wire-receiving point, the forward slightly bevelled or
wedge-like portions of said arms and tool, pass beneath the wire then lying against.
the abutment 385, and pocket it, to prevent its displacement, as in said figure, lifting
it, if necessary, snugly against the anvil behind the said abutment 385. The wire
will thus be confined in a four-walled pocket formed by the end of the stapling tool
and its abutment, and the face of the anvil and its abutment. As the stapling tools
advance, the abutment with which they are provided (namely, the shoulders m², n²,
and abutment 339, then aligned) bear, against the wire, and momentarily nips it
while it is being severed, thereafter acting to carry it onward, in which action and
movement the abutment 385 first acts as a nipping member, to hold the wire-length
during the operation of cutting it from the main body of wire, and during its initial
forward movement of onward travel, and thereafter as a yielding support for the
guidance of the wire-length, in the operation of forming it into a staple, the abutment
385 first resisting, under the action of its spring 386, and then yielding, so that the
wire length severed, while supported between the two abutments, is immediately
pressed off from the rear end of the abutment and onto its face, which movement of
it causes the abutment 385 to rise, so that its underface becomes aligned with the
projection or rib 384, as in Figure 90, the wire length, while being cut, and thereafter
until set, being thus held in contact with the setting bed 340, while the ends of the
wire-length are being bent up into staple-form by the anvil 350 forcing them into the
grooves in the bending arms 329, 330, as the setting bed descends, which operation
gradually proceeds as the anvil is traversed by the tools, and the plain face of the
anvil 350, and that part of it coincident with the surface of the carrier C² is
reached.
The rear, or wire-engaging end of the abutment 385, has a slight outward pitch
forward, so that while it will resist sufficiently to aid in the nipping of the wire, so as
to hold the severed wire length, the pitch of its end will allow the wire length to
pass up on to, and ride over, its face. This operation would be performed if this
abutment 385 was fixed and not spring-seated, so that it constituted an elongation of
the rib 384, substantially as is shown in Figure 90, and hence, in a broad sense, it is
a member co-operating with the forming tools, which is to be considered as if it
were rigid, and without widthwise limit within the dimensions of the anvil.
At its forward end, this anvil 350 is provided with side grooves 304, 305, to receive
the staple legs, and with side plates 314, 315, having inwardly bevelled inner faces
opposed to said grooves (see Figure 85), whereby the extremities of the staple legs
are given an additional bend in the direction in which they are ultimately bent in
the clinching operation. These plates 314, 315 (see Figure 86) have their inwardly
projecting bearing ledges increased, or wedge-like from rear to front, so that the
staple legs bent at right angles to the crown, in passing over the main portion of
the anvil 350 (but which lose that relation to their crowns, owing to the resiliency
of their composing steel wire), may enter between these angular-ledged plates 314, 315,
and passing over them, be given an additional inward bend, the grooves 304, 305,
receiving said inwardly bent ends, and allowing them to pass freely off this anvil,
and without distortion.
The setting dies 346 with which the cylinder D2 is provided, and with which the
staple setting tools coact in performing the clinching operation, are made adjustable
therein, and are constructed as follows:-

page_text: Each die is constructed so as to be supported in a holder 344, as will be presently
explained, and this holder 344 is a long narrow member (see Figure 92), having a
curved face corresponding to the arc of the cylinder which carries it,-said holder
being supported in a recess or seat formed in the cylinder, and the rearward or die
carrying end of which holder projects into a recess in which the rotating folding
blade is housed, said blade being recessed to escape the die in its rotation, as is
described in British Patent No. 3394 of 1893. The die 346 has but a slight recess,
curved as is described in said patent, so as to properly perform the clinching
action.
Said die is preferably a steel block with bevelled sides, as shown, to capacitate it to
be held in a properly-shaped recess 345, at the end of the holder 344, its retention
in the holder being secured by means of set screws 388, 389. The holder 344 is
held in its seat in the carrier or cylinder D2 by means of screws 393, 394, and 395,
the holes u2w2 through which the screws, 393, 394, pass being large enough to
admit of lengthwise adjustment of the holder, controlled by the eccentric head of
screw 395 bearing against the wall of the hole 2, which it snugly fits.
It will have been observed that the stapling tool, in so far as its functions of
holding the wire whilst it is being severed, and of advancing the severed length over
the underface of the former anvil, is concerned, has a recess 312, that enables it to
pass over the rib projecting centrally from the anvil, as well as to avoid interference
with the abutment 385.
Having thus set forth the construction and arrangement of the various parts, the
operation of forming, setting, and clinching a staple, will now be explained.
The associated plies of material passing between the carriers 02, D², have two
staples set so as to form a transverse binding line therein. As the mechanisms are
moved, the wire-feeding devices are in operation by reason of the pinion 445 being
secured in mesh with the driving wheel 434, and operate to advance the wire beneath
the anvil 350 to a length sufficient for the formation of a staple at each semi-
revolution of the carrier C. The outward feeding movement of the wire projects it
over the face of the cutting blade 308, and under the face of the rear end of the
anvil 350, in close proximity to, or against the angular rearward edge of the
abutment 385, the protruded end thus being supported for the action of the tools
that are to operate upon it. This protrusion of the wire length is so timed, that
although the wire feed is a constantly operating one, a proper length will be presented
to the action of the staple-forming tools in their rotative sweep or circular path of
travel.
As each staple-forming, tool, in its rotative travel, reaches the point where the
wire length is protruded, the parts constituting the abutment of the bending arms
and the setting tool simultaneously contact with the wire length, and bear it snugly
against the abutment 385, while the tappet 347 engages the cam face of the cutting
blade 308 (see Figure 73), so that the cutting of the wire-length takes place while
the wire is nipped by, or confined between, the abutment 385 on the anvil and the
abutment formed by the shoulders m² m², and projection 339 on the stapling tools,
the result being, that the wire-length is prevented from jumping, or otherwise being
moved out of place during or after its severance, and will thereafter be surely held,
and transported, through the necessary operations of forming it into a staple and
setting it, instead of flying out of the tools, or becoming displaced therein, as such-
like bodies are liable to do, when unsupported even momentarily.
After the wire length is severed, it is moved from the position shown in Figure 89,
up onto the face of the abutment 385, as in Figure 90, which movement will have
rocked said abutment upward, until it is arrested in facial alignment with the rib 384.
Meanwhile, the wire length being carried onward over the anvil 350, is gradually
pressed thereby, owing to the eccentric relation of the face of the anvil to the
carrier C², into staple form, by the coaction of the arms 329, 330 with said anvil, as
is well understood, the result being, that by the time it reaches the point where the
recesses 304, 305 begin, the wire length will have been formed into a complete staple,
the legs of which will be at right angles to its crown.

page_text: Thus formed, they will spring apart, and destroy this right-angular form, but as
they enter and pass between the faces of the angular-ledged plates 314, 315, they
will have their outer or free ends bent inwardly, as is illustrated in Figure 85, said
bent ends entering into the recesses 304, 305, by which operation their ends are
bent into a shape that will prevent any tendency for them to spread apart in the
setting and clinching operation, or, otherwise stated, so shaped that, in the operations
of inserting them and finally clinching them, the action of the tools upon them
will be aided in the performance of a perfect clinching action, with the staple legs
laid snugly together, and flat upon the face of the material.
The formed staple, complete at such, when it passes off the forward end of the
anvil 350, is held in the arms 329, 330, with its crown practically on a line with the
surface of the cylinder, and with its legs protruded therefrom, and pointed in
the direction it is to take in entering through the material. As the rotation of the
carrier proceeds, the protruded legs are brought into contact with, and forced through,
the material, as the point of contact between the carries C2D2 is approached, and
during the close approach to this point, and passage thereof by the stapling tools,
the staple legs will enter into the setting die, and be gradually bent or clinched down
thereby, the arms 329, 330 receding in timely coaction with the clinching movement
of the staple legs.
The term "collecting mechanism" is used in the claims to indicate any sort of
