page_text: Clinching Metallic Staples.
I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN MACHINES OR APPARATUS FOR INSERTING
AND CLINCHING METALLIC STAPLES to be as follows:―
"
My invention relates to machinery or apparatus for inserting and clinching
metallic staples, in which apparatus the staples are automatically delivered to the
presenting and inserting mechanism thereof and driven thereby through the
underlying books, papers &; the legs of the staples being simultaneously bent up
or clinched on the under side of the material by contact with clinching mechanism
in the frame of said machinery.
The said invention consists primarily of a frame containing in itself and as a
part thereof, a magazine for receiving, and for guiding to the staple channel of the
inserting mechanism, a row or train of staples arranged on a bar or mandrel
inserted in said magazine; said frame having also a vertically recessed arm or
arms for supporting and guiding the staple presenting and inserting devices and
the mechanism which actuate the same, and having also a base plate supporting a
clinching device. Secondly of the automatic staple feeding mechanism. Thirdly
of the staple presenting and inserting mechanisms and the means for vertically
reciprocating the same, whereby the staples contained in the magazine are each,
one by one, successively received into and brought to the surface of the material
to be operated upon and driven through the same. Fourthly, in the combination
with the frame of the machine, of the staple presenting and inserting mechanism,
and an underlying vertically adjustable clinching device whereby the machine
can be adjusted to varying thicknesses of materials to be wire-stitched; and lastly
in the combination and arrangement of these several mechanisms constituting
a complete machine for receiving a quantity of staples arranged in train, and

page_text: automatically feeding, presenting; driving and clinching the same by a continuous
operation.
The frame of the machine may be formed in a single piece, consisting of a base
recessed to receive the clinching block, and having an arm arising therefrom and
extending toward the front of the machine and terminating in two guide sockets
situate one above the other and in a vertical line with the said recess. An extension
piece terminating in a socket is provided, to receive the pin which pivots the
operating lever. The lower part of the said arm is so cast as to form in itself
a magazine for receiving a bar or mandrel of string staples; it being important in
this part of the frame that the interior top and inner side of the magazine should
be perfectly plain to coincide on these two surfaces with a square sided mandrel:
these parts forming the main portion of the staple-feeding device.
For small machines for office desk use, the frame may be provided with a single
guide because no actuating springs are used therein as in the large machine.
In the recess in the base of the machine in a vertical line with the guiding
sockets, is secured a clinching plate or anvil which is a simple metal block having
a recessed circular cavity on its face, or in the form of a slot, the staple legs being
bent over by coming in contact with the inclined surfaces of the slot or circular
cavity when driven down by pressure on the crown as hereinafter mentioned.
This anvil is mounted on a screw working into the recess in the base plate of the
frame which recess is screw-threaded so as to adjust the anvil as to height and to
enable it (as the papers to be stitched rest thereon) to bring the upper surface of
such papers to a point where it will be reached by the guide-block which drops
downward on the descent of the actuating mechanism. A plate vertically adjustable
to the height of the anvil by any convenient means, is secured to the base plate or
swings on a pivot, and forms a convenient work supporting table on which the
material to be wire stitched can be placed during the operation; and a gauge plate
with a slotted arm held in place on the base plate by a thumb screw, serves as a
convenient guide or gauge for regulating the line of staple stitching on the edge of
the books or papers to be operated upon.
The staple driving mechanism is sometimes operated by means of a plunger
moving vertically in the guiding socket and operated upon and depressed by
means of the said operating lever pivotted to the extension of the frame and
linked to the plunger. The plunger receives at its lower end the upper extremity
of the staple driver which is secured thereto by a set-screw; and to the plunger is
also secured a collar of circular shape and larger in diameter than the diameter of
the plunger, in order to afford a bearing surface for a large spiral spring placed
between its under face and the upper side of the lower guiding socket, and which
spring when depressed in the operation of the machine, serves by pressing up
against the collar of the plunger, to restore the guide-block, staple driver, and
staple guiding mechanisms, all by one upward movement of the plunger, aided by
a book of the driver engaging with a lug of the guide-block, and by an inner
spring hereinafter mentioned, to their several normal positions respectively after
the completion of each downward movement produced by pressure from the
operating lever.
Secured to the lower end of the plunger is a driver which moves vertically in
a guide-block which slides up and down in the lower guide socket.
The driver consist of a steel bar cylindrical at its upper end and with flat
sides at its lower end where it enters the staple channel preferably terminating in
a groove to fit the crown of the staple, and on the extreme end of one side is a
hook or narrow projection. Within the lower guide socket is a hollow partly
cylindrical guide-block of hard metal constructed with recesses and grooves. This
guide block is not held or restrained within the lower guide socket, but is free
to move up and down therein and performs the double function of a staple guide
(aided by the guard plate) and a driver guide, to bring the staple and stupling
mechanism to the surface of the book or papers to be wire stitched.

page_text: An inner spiral spring rests upon the top of the guide block encasing the driver
and presses by its upper end against the lower end of the plunger, and performs
the single function of counteracting the outer spring in its relation to the guide
block so that when the plunger descends the pressure of the inner spring will cause
the guide block to move downward in the lower guide socket and fall upon the
book or papers between it and the clinching anvil and thus aided by the adjustable
anvil constitute adjusting mechanism to adapt the apparatus to stitch varying
thicknesses of books or papers.
This downward movement of the guide-block is wholly independent of any
movement of the driving mechanism, the end of the driver, at the moment when
the guide-block falls as described, being at a point in the channel guide of the said
guide block a short distance above the crown of the staple which by the previous
upward movement of the driver was permitted to be ejected from the staple feeding
magazine, over the guard plate, into the staple channel and subsequently into the
groove formed between it and the lower end of the guide block ready to be driven
into the book or paper lying between the end of the guide block and the clinching
anvil, when reached by the lower end of the driver in its further and subsequent
downward movement actuated by the plunger.
On the reverse movement of the parts, it will be noticed that the guide block
is carried up to its normal position in the lower guide socket by means of the
hook of the driver, which hook is always below a pin or lug secured in the
recess of the guide block. This upward motion brings the guide block so that its
recess and guard plate are under and opposite respectively to the mandril and
block of the staple feeding device, ready for the next downward movement to again
perform the other several operations herein before described.
The guide block is bored out cylindrically as deep as the recess where it is
recessed externally and again more deeply recessed and channelled internally The
guard plate has sides equal in width to the sides of the guide block and as thick as
the recess, so that when fitted thereon it will form with the channel of the guide
block a groove for the descending staple and a groove or guide for the staple
driven, of corresponding shape, the guard plate is not screwed to the magazine but
to the guide block, but the guard plate fits against the lower part of the magazine,
and has rounded surfaces so that the staple ejected from the magazine will fall
easily over the guard plate and into the staple groove of the guide block.
The staple feeding mechanism is the same for large and small machines excepting
that in the former in consequence of the lower guide socket, a projecting block is
secured to the forward end of the magazine to bring the ejecting staple in line
with the vertically moving driver in the guide block which in turn reciprocates
vertically in the lower guide socket, (this lower socket being dispensed with in the
small form of the machine; and a second small block in the base of the magazine
resting in the slot of the guard plate to guide the staple after it leaves the mandrel,
to this edge of the guide-plate.
This magazine cast in the frame of the machine, has a flat or straight sided
internal top and inner side, and receives in its interior thus formed, a bar or
mandrel with at least three sides coinciding therewith and being capable of
receiving and supporting a number of wire staples arranged in train thereon.
It may be slotted longitudinally at each end to temporarily receive a band or cord
to hold the staples in place thereon while not in place in the machine.
A convenient mode of putting up such staples for shipment is to place them
upon a stick.
If the mandrel is permanently secured in the magazine, the staples are slipped
off the stick on to the mandrel, by placing the end of the former in the magazine
against the end of the latter and pushing them on to it. The mandrel may how-
ever be made removable and secured in place in the magazine by means of a
thumb screw.
The mandrel is slightly smaller than the interior of the magazine
in order that when placed therein there shall be a space between the upper and

page_text: inner sides of it and the magazine slightly more than the thickness of the staple,
80 as to afford a space between the two of the size and shape of the crown and
inner leg of the staple so as to form a guide therefor in its passage to the staple
channel of the inserting mechanism. By means of this device all unnecessary parts
are dispensed with as the staple needs only a top guide, for its crown and a side
guide for its inner leg, to guide it along the mandrel with certainty to its
destination in the staple channel.
The staples are automatically pushed forward on the mandrel by means of a
sliding pusher rod inserted in the magazine from its rear end and fitting around
the top and inner side of the mandrel, and bearing against the last staple in the
train. This pusher is capable of being moved forward until the last staple is
pushed forward into the staple channel of the guide block and it is so operated by
means of a pull spring or elastic band fastened to the curved end of the rod and to
a finger on the top of the magazine.
In the small machine the plunger is reciprocated in the upper socket and moves
the driver with which it is connected. This plunger is merely a square or
cylindrical bar fitting accurately in the said socket. No collar is here needed
as the lower guide socket and the spiral springs are dispended with, for in this
machine frictional contact only of the driver with the guide block is depended
upon to vertically reciprocate the latter Here also the staple presenting and
inserting mechanism consists of a guide block and driver both of which are recipro-
cated vertically the former by internal frictional contact with the driver, and the
latter by being secured to the lower end of the plunger. This guide block is a
vertically slotted block of metal with a vertical recess to form a staple channel or
groove as wide as the staple and leading from the base of the slot downward to the
under face of the guide block, and is provided with a projecting arm on the outer
side. The slot and channelled recess being of a size and form to permit the passage
downward therein of the driver, and of the staples received into such slot from the
magazine.
The guide block is preferably slotted to its extreme base, otherwise the staple
groove could not be cut therein, but if slotted its entire length a guard plate is
secured thereto to form such staple groove. In adjusting the guide block in the
frame, its inner side bears against the side of the frame and at its highest point of
reciprocation the base of the slot is in a line just below the ends of the staple legs,
the end of the mandrel being cut away to the depth of the guard plate and resting
thereon thus forming a continuation of the staple groove. The width of the
mandrel being narrower than the slot in the guide block, by the thickness of the
two legs of the staple, forms a guide for each leg of the staple to deliver it with
certainty and precision to the vertical channelled staple groove.
The guide block is held in position and partly guided in its vertical reciprocation
by a securing clamp hung on a pin in the frame and fastened in position by &
thumb screw; this clamp having an inwardly projecting lower end and an inner
flat side against which the projecting arm of the guide block constantly bears.
The guide block is thus stopped in its descent by contact with the inwardly
projecting end of the clamp, and in its ascent by the socket in the arm of the
machine; and it has therefore a very limited vertical travel.
The driver is perfectly flat and fits accurately in the slot and channelled staple
groove of the guide block, and the latter is reciprocated solely by frictional contact
with the driver moving up and down in it.
The operation of both forms of machine is as follows:-
The upper movement of the driver in the slot of the guide block, elevates the
latter, until its recess over the guard plate is opposite the mandrel in the magazine;
a further upward movement of the driver passes the end of the mandrel and
permits a staple thereof to be pushed, by the pressure on the train of staples into
the channel of the guide block; such action taking place because the driver passes
and repasses in its upward and downward motions the end of the mandrel (or the

page_text: magazine block in the large machine) and because the spring pressure on the
pusher rod bearing against the train of staples has a tendency to move them
forward. As the driver rises above the end of the mandrel the slotted space it
occupied in the lower end of the guide block is open to permit one staple from the
mandrel to be received therein. A downward movement of the plunger carries
down the driver, and by its action the guide block to the surface of the papers to
be stitched; a further downward movement of the driver, which at this time has
reached the crown of the staple, drives the staple in the channel groove down
through it and through the paper or book beneath, where its legs, coming in contact
with the inclined sides of the circular cavity in the underlying clinching auvil, are
bent up flat or clinched against the underside of the paper. The plunger being
again raised by the lever, to its full height, or until the driver has passed the open
inner of the magazine, a second staple is ejected into the slot of the guide block,
and the operation is repeated as before.

I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, 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:-
My invention relates to machinery or apparatus for inserting and clinching
metallic staples, in which apparatus the staples are automatically delivered to the
presenting and inserting mechanism thereof, and driven thereby through the
underlying books, papers &°; the legs of the staples being simultaneously bent up
or clinched on the underside of the material by contact with clinching mechanism
in the frame of said machinery.
The said invention consists primarily of a frame containing in itself and as a
part thereof, a magazine for receiving, and for guiding to the staple channel of the
inserting mechanism, a row or train of staples arranged on a bar or mandral
inserted in said magazine; said frame having also a vertically recessed arm or
arms for supporting and guiding the staple presenting and inserting devices and
the mechanisms which actuate the same, and having also a base plate supporting
a clinching device. Secondly of the automatic staple feeding mechanism. Thirdly
of the staple presenting and inserting mechanisms and the means for vertically
reciprocating the same, whereby the staples contained in the magazine are each,
one by one, successively received into and brought to the surface of the material
to be operated upon and driven through the same. Fourthly, in the combination
with the frame of the machine, of the staple presenting and inserting mechanism,
and an underlying vertically adjustable clinching device whereby the machine
can be adjusted to varying thicknesses of materials to be wire-stitched; and
lastly in the combination and arrangement of these several mechanisms constituting
a complete machine for receiving a quantity of staples arranged in train, and
automatically feeding presenting, driving and clinching the same by a continuous
operation.

Figure 22 is a view of the plunger and driver adapted to this modified form of
machine shown in Figure 16 and
Figure 23 is a view, from the inside, of the guide block thereof.
Like letters of reference indicate corresponding parts in the several Figures.
The frame of the machine as shown in Figure 2, is a cast metal structure in a
single piece, consisting of the base A recessed at a to receive the clinching block,
and having an arm B arising therefrom and extending toward the front of the
machine and terminating in two sockets C and E, situated one above the other and
in a vertical line with the recess a An extension piece terminating in a socket c
is provided, to receive the pin which pivots the lever L. The lower part of the
arm B is so cast as to form in itself a magazine for receiving a bar or mandrel T
of strung staples; it being important in this part of the frame that the interior
top and inner side of the magazine should be perfectly plain to coincide on those
two surfaces with a square sided mandrel; these parts forming the main portion
of the staple feeding device.
In Figure 17 is shown the frame for the machine shown in side elevation in
Figure 16, adapted for office desk use. This frame differs only from that shown
in Figure 2 in not having any lower socket E, because no actuating springs are
used therein as in the large machine.
In the recess a in the base of the machine in a vertical line, with the sockets, is
secured a clinching plate or anvil F which is a simple metal block having a recessed
circular cavity on its face, or in the form of a slot, the staple legs being bent over
by coming in contact with the inclined surfaces of the slot or circular cavity when
driven down by pressure on the crown as hereinafter mentioned. This anvil E is
mounted on a screw working in the screw threaded recess a in the base plate of
the frame, so as to adjust it as to height and to enable it (as the papers to be
stitched rest therein) to bring the upper surface of such papers to a point where
it will be reached by the guide-block which drops downward on the descent of the
actuating mechanism. A plate 4 vertically adjustable to the height of the anvil
by any convenient means, is secured to the base plate or swings on a pivot, and
forms a convenient work supporting table on which the material to be wire
stitched can be placed during the operation; and a guage plate H with a slotted
arm, held in place on the base plate by a thumb screw 5, serves as a con-
venient guide or gauge for regulating the line of staple stitching on the edge of
the books or papers to be operated upon, but I make no claim for the plate 4 and
guage H

page_text: In Figure 1 the staple driving mechanism is operated by means of a plunger K
moving vertically in the socket 'C and operated upon and depressed by means of
pressure imparted from the lever L pivotted at c and linked to it at a. The
plunger represented in Figure 1 receives at its lower end the upper extremity of
the staple driver S (Figure 5) which is secured thereto by a set-screw; and to
the plunger K is also secured a collar M (Figure 1) of circular shape and larger in
diameter than the diameter of the plunger, in order to afford a bearing surface for
a large spiral spring N placed between its under face and the upper side of. the
socket E; which spring when depressed in the operation of the machine, serves
by pressing up against the collar M of the plunger, to restore the guide-block,
staple-driver, and staple guiding mechanisms, all by one upward movement of the
plunger, aided by the hook h of the driver engaging with the lug k of the guide-
block, and by the inner spring r as hereinafter mentioned, to their several normal
positions respectively, after the completion of each downward movement produced
by pressure from the lever L.
Secured to the lower end of the plunger K is a driver S which moves vertically
in the guide-block P, which in turn slides up and down in the socket E.
The driver S, as shown in Figure 5 consists of a steel bar cylindrical at its upper
end and with flat sides at its lower end where it enters the staple channel
preferably terminating in a groove to fit the crown of the staple, and on the
extreme end of one side is a hook or narrow projection h. Within the socket E
is a hollow partly cylindrical guide-block P (see figures 4 and 14) of hard metal,
constructed with the recesses and grooves as shown in said Figure 14 which is the
inner side. This guide-block is not held or restrained within the socket E but is
free to move up and down therein and performs the double function of a staple
guide, (acted by the guard plate) and a driver guide to bring the staple and
stapling mechanism to the surface of the book or papers to be wire stitched.
An inner spiral spring R rests upon the top of the guide block P (see figure 4)
encasing the driver S, and presses by its upper end against the lower end of the
plunger K, and performs the single function of counteracting the outer spring N in
its relation to the guide block P, so that when the plunger K descends the pressure
of the inner spring R will cause the guide block to move downward in the socket E
and fall upon the book or papers between it and the clinching anvil F, and thus,
aided by the adjustable anvil, constitute adjusting mechanism to adapt the
apparatus to stitch varying thicknesses of books or papers.
This downward movement of the guide-bleck P is wholly independent of any
movement of the driving mechanism; the end of the driver S, at the moment
when the guide block P falls as described, being at a point in the channel guide of
the said guide block a short distance above the crown of the staple which by the
previous upward movement of the driver S was permitted to be ejected from the
staple feeding magazine, over the guard plate, into the staple channel and
subsequently into the groove formed between it and the lower end of the guide
block ready to be driven into the book or paper lying between the end of
the guide block and the clinching anvil, when reached by the lower end of the
driver S in its further and subsequent downward movement actuated by the
plunger K.
On the reverse movement of the parts, it will be noticed that the guide block P
is carried up to its normal position in the socket E by means of the hook h of the
driver, which hook is always below a pin or lug k secured in the recess of the
guide block (see figure 4). This upward motion brings the guide block so that its
recess 2 and guard plate 15 (see figure 14) are under and opposite respectively, to
the mandrel T and block 8 of the staple feeding device ready for the next
downward movement to again perform the other several operations hereinbefore
described.
The guide block P (see figure 14) is bored out cylindrically as deep as the
recess 19 where it is recessed externally, and again more deeply recessed at 17,

page_text: channelled internally as shown at 16 (Figure 13); The guard plate 15 (see
Figure 10) has sides equal in width to the sides 19 of the guide block and as thick
as the recess, so that when fitted therein (as in figure 14) will form with the
channel of the guide block a groove for the descending staple and a groove or
guide for the staple driver, of corresponding shape. The guard plate 15 is not
screwed to the magazine but to the guide block, but the guard plate fits against
the lower part of the magazine, and has rounded surfaces 14, so that the staple
ejected from the magazine will fall easily over the guard plate and into the staple
groove of the guide block.
The staple feeding mechanism is the same in both forms of the machine shown
in figures 1 and 16, excepting that in the former in consequence of the lower
socket, a projecting block 8 (see figures 2, 8 and 9) is secured to the forward end
of the magazine R to bring the ejecting staple in line with the vertically moving
driver in the guide block, which in turn reciprocates vertically in the lower
socket E. (this lower socket being dispensed with in the small form of the.
machine); and a second small block 20 in the base of the magazine, resting in
the slot of the guard plate to guide the staple after it leaves the mandrel, to the
edge of the guard-plate (see figures 8 and 9).
This magazine R, cast in the frame of the machine, has a flat or straight-sided
internal top and inner side and recesses in its interior thus formed, a bar or
mandrel T. with at least three sides coinciding and capable of receiving and
supporting a number of wire staples arranged in train thereon. It may be slotted
longitudinally at each end to temporarily receive a band or cord to hold the staples®
in place thereon, while not in place in the machine. In figure 12 is represented a
stick of string staples, which is a convenient mode of putting up such staples for
shipment. If the mandrel is permanently secured in the magazine the staples are
slipped off the stick into the mandrel, by placing the end of the former in the
magazine against the end of the latter and pushing them on to it. The mandrel T
may however be made removable and when taken out to be filled with staples is
secured in place in the magazine by means of a thumb screw 6 and 7. The
mandrel is slightly smaller than the interior of the magazine in order that when
placed therein there shall be a space between the upper and inner sides of it and
the magazine slightly more than the thickness of the staple, so as to afford a space
between the two of the size and form of the crown and inner leg of the staple and
serve as a guide therefor in its passage to the staple channel of the inserting
mechanism. By means of this device all unnecessary parts are dispensed with as
the staple needs only a top guide, for its crown, and a side guide for its inner leg,
to guide it along the mandrel with certainty to its destination in the staple channel.
The staples are automatically pushed forward on the mandrel T by means of a
sliding pusher rod X (Figure 15) inserted in the magazine from its rear end and
fitting around the top and inner side of the mandrel, and bearing against the last
staple in the train.
This pusher is capable of being moved forward until the last staple is pushed
forward into the staple channel of the guide block and it is so operated by means
of a pull spring or elastic band fastened to the curved end 12 of the rod and to a
finger 13 on the top of the magazine.
In the small machine shown in Figure 16, the plunger is reciprocated in the
upper socket C and moves the driver with which it is connected. This plunger is
merely a square or cylindrical bar fitting accurately in the said socket. No collar
is here needed as the lower socket E and the spiral springs are dispensed with, for
in this machine frictional contact only of the driver with the guide block is
depended upon to vertically reciprocate the latter. Here also the staple presenting.
and inserting mechanism consists of a guide block P and driver S. (Figures 22
and 23) both of which are reciprocated vertically, the former by internal frictional
contact with the driver, and the latter by being secured to the lower end of the
plunger. This guide block P is a vertically slotted block of metal with a vertical_

page_text: recess to form a staple channel of groove as wide as the staple and leading from the
base of the slot downward to the under face of the guide block and is provided
with a projecting arm 10 on the outer side, the slot and channelled recess being of
a size and form to permit the passage downward therein of the driver S and of the
staples received into such slot from the magazine. It will be noticed that the
guide block is not slotted to its extreme base, otherwise the staple groove could not
be cut therein. If slotted its entire length a guard plate 15 is secured thereto to
form such staple groove. In adjusting the guide block in the frame its inner side
bears against the side of the frame and at its highest point of reciprocation the base
of the slot is in a line just below the ends of the staple legs, the end of the mandrel
being cut away (see Figure 19) to the depth of the guard plate 15 and resting
thereon (see Figure 21) thus forming a continuation of the staple groove. The
mandrel being narrower than the slot in the guide block, by the thickness of the
two legs of the staple, forms a guide for each leg of the staple to deliver it with
certainty and precision to the vertical channelled staple-groove. The guide block
is held in position and partly guided in its vertical reciprocation by a securing
clamp G hung on a pin f in the frame and fastened in position by a thumb
screw d; this clamp having an inwardly projecting lower end e and an inner flat
side against which the projecting arm 10 of the guide block constantly bears. The
guide block is thus stopped in its descent by contact with the inwardly projecting
end of the clamp, and in its ascent by the socket C in the arm D of the machine
and it has therefore a very limited vertical travel.
The driver S is perfectly flat and fits accurately in the slot and channelled staple
groove of the guide block, and the latter is reciprocated solely by frictional contact
with the driver moving up and down in it.
The operation of the machine is as follows: In either form shown in Figures 1
and 16 respectively, the upper movement of the driver in the slot of the guide
block, elevates the latter, until its recess over the guard plate is opposite the
mandrel in the magaziue; in a further upward movement the driver passes the end
of the mandril and permits a staple thereof to be pushed by the pressure on the
train of staples, into the channel of the guide block; such action taking place
because the driver passes and repasses in its upward and downward motions the
end of the mandrel T (or the magazine block 20 in the large machine) and because
the spring pressure on the pusher rod bearing against the strain of staples has
a tendency to move them forward. As the driver rises above the end of the
mandrel the slotted space it occupied in the lower end of the guide block is opened
to permit one staple from the mandrel to be received therein. A downward
movement of the plunger carries down the driver, and by its action the guide block
to the surface of the papers to be stitched, a further downward movement of the
driver, which at this time has reached the crown of the staple, drives the staple in
the channel groove down through it and through the paper or book beneath, where
its legs, coming in contact with the inclined sides of the circular cavity in the
underlying clinching anvil, are bent up flat or clinched against the underside of the
paper. The plunger being again raised by the lever, to its full height, or until
the driver has passed the open inner end of the magazine, a second staple is ejected
into the slot of the guide block and the operation is repeated as before.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent I declare that what I claim is :-
First-Staple inserting and clinching mechanism, shown in Figure 1, consisting
of the frame A having socket bearings E and C and an underlying clinching
plate F; a plunger K vertically reciprocating within the upper socket C, and a
guide block P vertically reciprocating within the lower socket E; counteracting
spiral springs N and R, the latter acting with pressure between said plunger and
guide block and operating to depress the guide block on the downward movement

page_text: of the plunger, and the former acting with pressure between said lower socket
