Improvements in Machines for Forming and Driving Wire
Staples.
1, HENRY HARRIS LAKE, of the Firm of Haseltine Lake & Co., Patent
Agents, 45 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 has relation to wire-stapling machines, having for its object to
improve and simplify the construction and increase the efficiency thereof, and
consists in the provision of a novel form for each the wire-feeding; wire-cutting;
staple-forming and staple-driving mechanism and the means whereby the same may
be in continuous, as distinguished from intermittent, operation; the length of wire
fed and the pressure exerted thereon by the feeding devices varied, for the reception
of wire of dit erent gauges; and the length of stitch regulated.
My invention also consists in novel means whereby the position of the table,
relatively to the presser-bar of the machine, is governed by the thickness of the
pamphlet, etc., to be stapled, and in the provision of a novel form of clincher and
means for its operation.
My invention further consists in the details of construction and the combinations
of parts as hereinafter fully described and claimed and as illustrated in the accom-
panying drawings. To the end that the various and necessary operations of the
machine, for the production of work of the most approved character, may be
accomplished through the employment of the fewest possible parts and the least
complex motions. Conducing to durability, lightness and freedom from noise,
together with smoothness and rapidity of running and easiness of operation.

In said drawings, A represents the head of the machine, having therein a recess a
for the eccentric B, the latter being secured. on the forward end of the inain shaft B¹
and sustaining the pin b, said pin affording a bearing for the lower end of the
pitman C, the upper end of said pitman having its hearing on the pin e said pin
being secured in the driving-bar D.near the upper end of the latter. E. is a bell-
crank lever pivoted on the pin e, sustained by the head A, at one side thereof, said
lever having a slot e' in its shorter end and supporting the pin e¹ in its longer end,
said pine affording a bearing for one end of the link e, the latter forming the
actuating medium for the lever E, through having its other end journalled on the
eccentric pin b. As will be observed, the driving-bar D has therein, about mid way
of its length, a longitudinal slot d, the same affording a clearance for the pin f of the
presser-bar F, said pin passing through slot d and into the slot e' in the lever E,
the slot last mentioned permitting of freedom of movement therein of the pin, upon
the reciprocation of the presser-bar by said lever.
The lower end of the driving-bar D has therein a short recess d', of a depth
equal to the thickness of the driver D', having therein a round boss or projection d²,
said boss being provided for engagement with the opening d³ in the upper end of
the driver and said recess permitting of such upper end resting within the plane of
the surface of the bar D, so as to not interfere with the sliding freely of the presser
and driving-bars upou each other and within the box A' of the head A, said bars
being retained in operative relation with each other, and with their connections,
through the medium of the lid or plate a', the latter being secured in position by
the screws a².
The lower end of the presser-bar F is thickened or enlarged, as at f', such
enlargement having a vertical groove f' therein, the same forming a slide-way for
the driver D' and the latter being secured against dislodgment therefrom by the
combined cutter and former G, which is secured to the face of the enlargement by
the screws g g and extends over said groove, which screws pass thereinto from the
rear, and by the pins g¹ g'. The driver D being further retained in the groove f
by the guides, which latter are secured in recesses at the opposite sides of and
project, for a short distance, over the edges of said groove, forming a tube for
reception of the staple and serving to poise or hold such staple in position for
driving, the lower end of the presser-bar operating as a presser-foot, while the
space between the guides prevents the lodgment of any improperly formed staples
at the entrance to the tube and the consequent clogging thereof.
The cutter and former G is, as shown, of angular shape, having two depending
legs g² g³, the leg 9 having its lower end sharpened at its outer edge, as at g',
while the end of the leg g rounded. This cutting edge, in conjunction with
the block H, with which it is in close relation, operates to exert a shearing action
on the wire at the point where it passes from that portion of the slot / which is in
said block, thus separating it into the proper lengths.
I represents the anvil-block or support, the same being secured to the leg A'
of the head of the machine by means of the screw i, which screw passes through
said leg and into the support, the latter having its lower end forwardly extended,
foot-like, into a forming anvil I', said anvil being of such width as to permit of
its projecting between the legs of the cutter and former to such extent as that its
forward edge will barely clear the path of the driver, there being left a space
between the sides of the anvil and the adjacent sides of said cutter and former of
such width as to be equal to the thickness of the wire employed. Accordingly,
as such wire is cut off, in the manner herein before explained, the former will con-
tinue downwardly from the cutting position, causing the bending of the free ends
of the wire down against the sides of the anvil and the formation of the staple.
The upper end of the anvil-block or support sustains a transverse pin k, upon
the projecting ends of which are pivoted the pushers K K', the latter having their
lower ends forwardly extended and provided with the offsets k', the same permitting

page_text: such ends to overlap the ledges i of said anvil-block and project slightly over the
top of the anvil. These extensions k³ are diminished in thickness; so as to
permit of their interposition between the sides of said anvil and the adjacent edges
of the cutter and former; and have their front edges so inclined that they will
stand vertically, when the pushers are swung forwardly their full extent.
Permitting of the pushing of the staples squarely off the anvil.
The cross-bar L has secured thereto the pins l', which bear against the rear
edges of the pushers. The rod passes through a central opening in the cross-
bar and at its inner end is threaded and in engagement with a correspondingly
threaded socket in the leg A2, said rod having on its outer end the thumb-piece 1³,
between which and said cross-bar is interposed the spring L, said thumb-piece
affording means for screwing, in or out, the rod 12 and varying the pressure of the
encircling spring on the cross-bar and, consequently, the pressure of said pins on
the pushers.
M is the feed-bar of the machine, which is supported on one end of the shaft m,
such shaft being journalled in the boss m¹ on the head A of the machine, and
having on one edge the boss m³, the latter affording a bearing for the rock-shaft m³,
the forward end of which shaft has secured thereon an inverted semi-circular
disc m', while the rear end thereof has secured thereto the lower end of the curved
lever m², such lever being jointed, hinge-like to the arm o¹ of the eccentric strap B²,
through the medium of the pin m³.
n represents one of the feed-jaws, the same being a circular rod sustained in a
box or bearing N near the lower end of the bar M, having its ends rounded and
smooth, at its upper end abutting against the flat of the disc m and at its lower
end being opposed to the stationary jaw n', said jaw being also circular and is
secured in the lug 2, at the lower extremity of said bar M, by the screw n³ which
projects into a groove therein. It will be seen that the shaft m has thereon, at
the end opposite to that on which the bar M is secured, a rubber cushion m', the
same being interposed between two washers m³, which prevent access of oil thereto,
and being subject to the impact of the nut m³, which latter, also, serves to secure
the shaft m in the boss m¹.
Now, owing to the fact that the connection between the lever m³ and the feed-
bar M is loose, the shaft m³ being loosely journalled in the latter while the lever
is secured rigidly to such shaft, when the arm 6' is drawn by the eccentric towards
the left of the drawing the shaft m³ will simply turn in its bearings, without the
feed-bar moving, until it meets with a resistance sufficient to prevent its rotation.
This resistance is found in the feed-jaw n, the disc m' on said shaft coming into
contact with said jaw and the wire being interposed between it and the lower jaw.
When this occurs, which as before suggested, involves the gripping of the wire
by said jaws, the feed-bar M will move towards the left of the drawing, under the
draft exerted thereon by the eccentric arm 6' and accomplish the feeling of the
wire to the staple-forming devices. Obviously, the less easily the feed-bar moves
on its bearings, or the more friction therein to overcome, the more tightly must
the wire be grasped in order to produce a resistance in the shaft m which is
greater than that of the shaft m. Therefore, as the amount of friction in the
shaft last mentioned is varied so will the pressure of the feed-jaws on the wire
vary, thus said jaws are readily adjusted to suit wire of different sizes.
The amount or length of wire to be fed to the staple forming mechanism is
regulated by simply turning the thumb-screw o, by means of the wheel O, and
then locking it in position by the check-nut o', the latter having an arm for
facilitating its operation. As the distance is between the opposing ends of the
screw and the eccentric arm b', so will the eccentric move free without actu ting
the feed-bar, owing to the loose joint, aforesaid, between said bar and the lever m³.
When, however, the screw o and arm 6' come together the feed-bar will be
actuated, consequently the more the motion of the eccentric, before the movement
of said feed-bar, the shorter will be the length of wire fed, while, on the other
hand, the less of such motion the greater the length of wire.

page_text: Obviously, the feed-bar M may be actuated to equal effect by lengthening the
pin 6 sufficiently to permit of pivoting one end of a pitman thereon, the other end
of which latter being jointed to the lever m³, through the pin mo, the same as is
the eccentric-arm. The pin b, in this event, being a crank-pin; which, through
the intermediate connections, operates the feed, staple-forming and driving
mechanism; and the eccentric B a crank-disc. The advantage in the employment
of the strap B³, however, is that of greater compactness.
The reel P, which is supported by the arm p, secured to the head A of the
machine by the screw p³, is of ordinary form and provided with the usual
spring p², secured to the spindle upon which the reel rotates, which spring retards
the movement of such reel and prevents the unnecessary unwinding of the wire x
therefrom.
After leaving the reel the wire is, as usual, subjected to tension, for which
purpose any suitable device may be employed, such, for example, as that lettered R,
the same being in the form of a guide and having at its ends the loops or eyes rr
for the passage of said wire, the eyer being of about the width of the coil of
wire, while the eye is considerably narrower and operates to centre the wire
preparatory to its going through the straightening devices. Said guide or tension,
also, being pivotally supported on the outer end of the arm R¹, which arın is
secured on the rear end of the spindle p³ and has interposed between and secured
to it and the arm p, the spring r².
The wire-straighteners are shown at ss in the shape of small rollers, one of
which, is journalled on the pins in the end of the fixed arm s³, the latter being
secured to the arm S projecting laterally from the head A, and the other roller, s²,
having its bearing on the pins in one end of the pivoted curved-plate S', the
latier being provided with a circular bases and is adjustably secured to the arm S
by the screws. The wire after leaving the tension device, passing around the
plate S'; under the draught of the feed-bar; and between the rollers, which
latter operate to bend such wire in opposite directions and straighten it. The
plate S being swung on the screws so as to bring the axis of the roller s' nearer
to or farther from the axis of the roller s, according as the stiffness of said wire
requires.
After the wire is straightened and grasped by the feed-jaws n n' it is passed into
the slot formed by the block H and the guide-block H', said block and guide
each having half of said slot therein, while the guide H¹ is of such length and is
so disposed as to have its inner end in close relation with the rear of the anvil,
back of the path of the cutter and former, thus ensuring the invariable
introduction of the wire to said anvil and avoiding the bending of the same
theretofore by its striking the side of the anvil, or elsewhere. The detent or
dogs', pivoted on the pin in the extensions of the bases and maintained, by
the spring, in contact with the wire a, being of such shape at its free end as
to permit of the wire passing forwardly between it and the plate S' and operating
to wedge or jamb said wire, when a staple-length has been cut and the draught of
the feed-bar is released, preventing the tension-device from drawing the end of the
wire from said slot h.
In this connection it may be stated that for the formation of a deeper staple,
that is, one having longer legs, the block H is simply moved outwardly on the
guide H which it encloses, through loosening the screw in the slot h³,
substituting a cutter and former whose cutting edge is farther from the centre
than the one shown, which latter is detachably secured by the screws 99, and
again fixing the block in such position as to be in operative relation with the
cutter.
The table is supported by the lower arm 3 of the frame 2; said frame being
secured to the base 4 of the machine by the bolts 5; through the medium of the
box 6 which encloses the standard 7, said box having its lid 8 secured thereto by
the screws 9 and 10, which lid, by reason of there being a little clearance space
between its upper rear side and the upper edges of the sides of said box, as shown

page_text: at 11, operating as a clamp-plate to retain said standard in any adjusted position,
when pressure is exerted thereon by the screw 12. Said screw having thereon
the handle 13, to facilitate its operation, and passes through the centre of the
cross-bar 14, said bar being secured to a boss on each side of the box 6 by
the screws 15 and the screw 12 passing through a central threaded opening in the
cross-bar and bearing against the lid 8. The standard 7, at its upper end, is
provided with a head 16 to which the pedestal 17 of the table is fastened, by the
bolts 18.
As will be observed, the standard 7 has secured thereto by the screws 19, at a
point below the lower edge of the box, a plate 20, the same having secured thereto
the handle 21, the shank 22 of which handle serving as a gauge for regulating the
height of the table. Thus, when a book, for example, of a certain thickness is to
be stapled and the table is not at its proper height relatively to the presser-bar of
the machine, such book is inserted between the shank 22, of handle 21, and the
lower edge of the box 6. Then the screw 12 is loosened and the standard 7 and,
consequently, the table, raised by means of the handle 21 until the shank 22 of
the latter bears against the book aforesaid. Then the screw 12 is again tightened.
The effect being to bring the table into such relation with the presser-bar of the
machine that the distance between its lowest point of travel and said bar will be
equal to the thickness of the book to be stapled, avoiding any injury to either the
book or the machine. The distance between the shank of the handle 21 and the
lower edge of the box 6 being at all times equal to the distance between the table
and the lowest point reached by the foot of the presser-bar.
The clinching mechanism consists of the casing T₁ projecting through an
opening in the centre of the table T and provided with a cap-plate t, secured
thereto by the screws t', said casing having therein a broad transverse rib t³ upon
which and between it and said plate moves the slide t³, the lower end of said slide
having a lug provided with an opening to, through which opening passes the
screw 23 which connects the slide to the clincher-operating rod 24, said rod sliding
within a longitudinal groove 25 in the face of the standard 7 and being connected
at its lower end to the arm u of the bell-crank lever U. The upper end of the
slide is provided with pins to, upon which are pivoted the lower ends of the
links while the upper ends of said links are pivoted, in turn, on the pins to of
the clinchers to, the latter being pivoted on the pins 10 in the upper end of the
casing. The upper ends of the links are, as shown, inclined inwardly, so as to
avoid the crossing of centres by said ends and the consequent jamming of the
clinchers against the sides of the casing, which latter is secured to the standard by
the screw 26.
The bell-crank lever U is pivoted on the pin u' sustained in lugs formed on the
lower end of the standard 7, as at 27, the other end of said lever being connected to
the pitman u², which latter is pivoted on the pin us in the rotary disc U¹, said disc,
also, having a pin u upon which is pivoted one end of the connecting rod U2, the
upper end of such rod being pivotally connected to the lever V, which lever is
fulcrumed on the pin in the arm of the machine and has upon its free end a
friction-roller v', said roller being maintained, by the draught exerted on the lever U
by the spring w, in contact with the cam 2 on the main shaft B', thus the desired
reciprocation of the slide and the consequent operation of the clinchers t is
secured.
In order to have perfect control of the machine it is necessary to provide means
for applying power to and releasing the same from the shaft B', therefore the
collar 29 is secured rigidly on said shaft by the bolt 30, the hub of the pulley 28,
which latter is loosely journalled on said shaft, having sockets 31 therein for
reception of the rounded end 32, of the bolt 33, which bolt is hollow for reception
of the spring 34 and is retained within a recess in the collar by the disc or washer 35
secured to the end of said collar, which recess is round at the part through which
the end 32 of the bolt projects and is square at the point where the correspondingly

page_text: shaped rear portion 37 of said bolt lies, as shown at 36, said collar, also, serving to
keep the spring 34 in the position shown, said square portion 37 of the bolu 33
being provided with a projection 38.
Secured to the shoulder 39, on the frame of the machine, by screws, as at 40, is a
vertical box or casing having therein a latch 41, which latch and box have each a
pin numbered 42 and 43 to which are secured the ends of
spring 44, the lower
end of said latch being connected to the rod 45 and the upper end of the same having
thereon an inclined shoulder 46, which is in radial alignment with the path of the
projection 97, and a limiting stop 47. The rod 45 is connected at its lower end to
the treadle 48 and the treadle is pivoted on the pin 49, in lugs on the foot of the
base 4, as at 50.
The operation of this machine is as follows:
The wire a is first drawn from the reel P and the end thereof passed through the
eyes r of the tension-device; around the plate S' and between the rolls s
'; into
the feed-jaws n n'; through that portion of the slot h which is in the guide H¹; and
into the position shown in full lines in Figure 8 of the drawings.
.
Starting with the parts of the machine in the relation shown in Figures 1 and 2,
which is that assumed by such parts after the driving of a staple and immediately
preceding the feeding operation, the staple-former and driver being on the rise, said
former being about to clear the anvil and the lower end of the driving-bar, to which
latter said driver is attached, about to clear the cam-shoulders of the pushers.
Power is applied to the shaft B', through pulley 28, causing the rotation of the
eccentric B and the further rise of the driving-bar, through the medium of pitman C,
and a like direction of movement to be imparted to the presser-bar, to which latter
the former is secured, through the swinging outwardly of the upper end of the
lever E under the impulse exerted thereon by the link e. Said presser-bar then
rests, inomentarily, while the centre of the eccentric-pin b is crossing the horizontal
axis of the lever pin e², the former G having, by this time cleared the anvil and the
lower end of the driving-bar cleared said cam-shoulders. The driver, at the same
time, being above the plane of said anvil. The wire, meanwhile, has been fed onto
the rear part of said anvil by the feed-mechanism, whereupon the pushers K K' are
free to swing forwardly, under the impulse of the spring L³, pushing said wire
forwardly on the auvil until their shoulders abut against the former G, such wire
being thus brought into the position shown in dotted lines in Fig. 8, where it is in
the path of said former.
Now the presser-bar descends, causing the cutting off of the proper length of
wire and the bending of the ends of the same over the anvil, by the former.
Producing the desired staple. Such descent continuing until the upper part of the
former clears the shoulders k¹k, when the pushers swing still further forwardly and
sweep the completed staple squarely off the anvil into the position shown at y,
Fig. 12, where it is in the path of the driver.
By this time the lower end of the driving-bar, which latter has been steadily
descending, comes into collision with said shoulders, causing the return of the
pushers to their initial positions. Which motion, being continued, results in the
driving of the staple through the article to be stapled, by the driver D', the presser-
bar having, in the interim, come into contact with and exerting the proper degree
of pressure on the same. Such pressure being continued during the clinching
operation, because of the resting, for the time being, of said presser-bar in this
position, by reason of the fact that the pin b, which operates said bar through the
link e, has reached the limit of its inward swing, clearance for which being afforded
by the curve in the pitman C, and said link simply turning on the pin without
actuating said lever.
As will be readily understood, the clinchers remain inactive while the operations
above described are taking place, the roller ol being in contact with the lower
part of the cam and, upon the completion thereof, said roiler strikes the higher
portion of said cam and causes said clinchers, through the intermediate connections,

page_text: to swing upwardly and bend the ends of the staple close to the article stapled,
effecting the desired stapling.
At this stage the eccentric has carried the pin b a portion of its up-stroke,
carrying with it the driving-bar, whereupon the presser-bar and former rise until
the upper part of said former is opposite the cam-shoulders of the pushers and the
lower part or cutting edge clears the top of the anvil, the lower end of said driving-
bar having, meantime, cleared said shoulders, permitting said pushers to shove the
wire, which has been fed in by the feed-bar, from the slot in the guide H¹ and the
back of the anvil, to the front of the latter and into the slot in the cutting-block H,
where such wire is in the path of the cutter and former and the parts in position
for a repetition of the operations just described.
Upon the cutting off of a length of wire, which occurs when the eccentric has
accomplished about half of its up-stroke, the feed-bar M, under the impulse of the
eccentric-arm, swings back until the completion of half of the down-stroke of said
eccentric, when the wire is gripped by the jaws n n', in the manner hereinbefore
described, and said bar swings inwardly again and feeds another length of wire into
the guide H' and the rear portion of the anvil, from whence it is pushed forwardly
by the pushers.
The employment of spring-pressure for impelling the pushers forwardly, permits of
the bringing of a single length of wire, of any thickness, directly under the former
and the same, when formed into a staple, being placed in the path of the driver,
before the admission of another length of wire to the front part of the anvil. Said
pushers accommodating themselves to various thicknesses of wire, ensuring the
invariable placing of but one length of the same, be it ever so fine, under the cutter
and former and avoiding the accidental driving of two or more staples at one point,
obviating the necessity for the removal and substitution of parts, or other means,
for adapting the machine for reception of wire of different thicknesses.
