Improvements relating to Machines for Inserting and Clinching
Wire Staples, Chiefly Designed for use in the Manufacture of
Boots and Shoes.
I, HORACE E. CUNNINGHAM of Bridgewater, Pennsylvania, United States of
America, Machinist, do hereby declare the nature of this invention to be as
follows:-
My invention relates to machines for inserting and clinching wire staples.
A machine constructed according to my said invention comprises a shaft, whereby.
the various parts of the machine are set in motion. A shoe or other article to be
stapled is placed on a horn, and there is a wedge which rises so as to hold the shoe
during the operation to which it is to be subjected.
There is a wheel or carrier which rotates, and is provided with teeth which are
strung with staples the said staples being carried through a fork and then horizontally
over a block, the teeth then leaving the guide, the subsequent staples advancing
those in the guide. The staples then drop on the guide in an upright position, and
a bar, prevents them from improperly leaving said guide.
A stripper now rises, and strips the first staple from the guide, and a carriage,
advances, so that the carrier comes under the staple-driver. Meanwhile the awls have
been lowered, and they pierce the shoe at the place to be stapled. The said awls
now rise and the staple is carried over the shoe in line with the opening therein.
The carriage then advances, and a staple-driver, is moved over the staple held by the
carrier. The said staple-driver descends and the carrier withdraws, and the staple is
driven into the shoe, and as the horn is made of metal or other hard material, the
legs of the staple striking the same are bent and clinched, and another staple is
thereby firmly secured in position. A tooth now lowers and moves inwardly, and as
it reaches the shoe, it takes hold of the same and advances it the distance required,
after which it returns to its normal position. The shoe is again pierced at a fresh
place, and another staple is taken from the guide located over the shoe, and driven
into the same and clinched, and so the operations are repeated until the work is
finished, the shoe then being removed.

Figure 17 represents a front view of the lifting device of the dogs of a ratchet,
to be hereinafter explained.
Figure 18 represents a section on line, Figure 17.
Similar letters and numerals of reference indicate corresponding parts in the several
figures.
A designates the frame of the machine, and B a hollow column or stand sup-
porting the same.
C designates the driving shaft which is mounted on the upper part of the frame A,
and carrying a worm 1, which meshes with a worm wheel 2, the latter being
secured to the diagonal shaft 3, the latter being mounted on the upper part of the
frame A, and carrying at its lower end a bevil wheel 4, with which meshes a bevel
pinion 5, secured to the horizontal shaft 6 whose bearings are on the frame A.
Secured to the shaft 6, is a staple-carrying wheel D, whose periphery is provided
with teeth 7, said wheel dipping into a staple supply box E, which is supported on
the lower portion of the frame of the machine.
Above the wheel D, is a depending stripper 8, which is forked so as to embrace the
teeth 7, as the wheel enters said stripper, and supported above said stripper is a
flanged guide 3, below which is a race-way 10, for the entrance of staples, said guide
and race-way being partly slotted to permit the entrance of the teeth 7, and the
periphery of the wheel D. Connected with the race-way 10, is an inclined upright
guide 11, which is of less width than the guide 9, so that the staples may be strung
thereon in upright position, as will be hereinafter set forth.
The stripper is pivoted to the race-way 10, and the latter is secured to a bracket A*,
which latter also supports the guide 11, said bracket being connected with a
carriage 61, to be hereinafter referred to.
On the end of the shaft C, opposite to the driving pulley, is a feathered cam 12, and
also a fixed cam 13.
Encircling the cam 12, is a yoke 15, with which is connected the awl-carrying
bar 16, the awl carrier E¹, being pivoted to said bar, and made of the form of an
elbow lever, each limb carrying a pair of awls, the pairs being of different dimensions,
so as to pierce the work for different sizes of staples.
Each limb carries a latch 17, which is pivoted to the limb, and pressed upward by
a spring 18, against the lower end of the bar 16, said end being notched to receive
the shank of the latch.
By lowering the latch, the awl-carrier is released and it may be rotated, so as to set
the other pair of awls in upright or operative position, after which the latch is let go,
and forced by the spring 18, into engagement with the bar 16, thus latching or
locking the awl-carrier.

page_text: The cam 13 is adapted to engage with the head of the bar 16, and to depress the
same while the yoke 15 is adapted to raise said bar, by which provisions the "awls are
first forced into the work, and then withdrawn therefrom.
The upper end of the yoke has a hook-shapod piece 19 which embraces the outer
side of the cam 12, and the head of the bar 16 forms a shoulder 20, which is suffi-
ciently high, to be engaged by the camn 13, as will be seen in enlarged view,
Figure 7.
The awl carrying bar 16, and staple driver F, are fitted to a carriage G, so as to
rise and fall thereon, said carriage being supported on the frame A, and receiving
lateral motion by means of a cain 22, which is secured to a toothed wheel 23, the
latter being mounted on the shaft 21 whose bearings are on the frame A, said wheel
meshing with a pinion 25, which is secured to the driving shaft C, it being noticed
that by the action of the carriage G, the awl-carrier and staple-driver are moved over
the work to be stapled.
On the wheel 23 is a laterally-projecting pin 26, which engages with an arm 27, on
a rotary shaft 28, the latter being provided with a cam for operating a work feeding
device, as will be hereinafter more particularly referred to.
E designates a horn or holder for the work, the same being formed of a vertically-
moving shaft, properly bent and having its upper end adjacent to and below the awl-
carrier, said horn being provided with a balancing spring 30, and resting on_a
wedge J, which is supported on an inclined plane 31, at the base of the column B.
Pivoted to the wedge J, is an arm 32, which is connected with a crank 33, secured to
a shaft 34, which carries a number of toothed segments 34*.
The shaft 34 is mounted at the base of the column B, and carries a loose arm 35, on
which is hinged a pawl 36, which engages with a ratchet 37, fixed to said shaft 34.
The arm 35 is connected with a rising and falling arm K, which receives motion by
moans of a cam 38, at the top of the machine. On the base of the column B, is an
upright piece 39, with which the lower limb of the pawl 36, is adapted to engage so
as to throw off said pawl from the ratchet 37.
Depending from a carriage G¹, which is freely fitted within the base of the
carriage G, and is operated by a lever A', through the medium of the cam 22³, is a
staple-carrier L, which consists of a vertical rod having a recess 40 near its lower end,
said recess being adjacent to the lower end of the inclined guide 11.
The cam 22, is connected with the wheel 23. Below the carrier L, is a staple
stripper M, which is vertically guided on the column B, and has its upper end adjacent
to the lower end of the inclined guide 11. Connected with the stripper M, is a
lever M¹, which is pivoted to the column B, and has its end engaged by a ratchet 41,
the shaft of which carries a ratchet 42, it being noticed that the ratchet +1, has four
teeth, and the ratchet 42, twice said number, so that the lever M, receives one motion,
to two rotations of the driving shaft C.,
The ratchet 42, is engaged by a pawl 43, which is hung on an arm 44, to which
is pivoted a rod or arm 45, which is operated by a cam 46, the latter being secured
to the shaft C.
Aside of the guide 11, is a bar 47, which is attached to a rotary rod 48, and has
pressing against it a spring 49, secured to the boarings of said rod, see Figures 3 and 5.
Engaging with a projection 50, on the lower end of the rod, is a finger 51, which
is connected with the stripper M, so that as the stripper falls, the finger comes in
contact with the side of the projection 50, and moves the same, thus rotating the
rod 48, and imparting outward motion to the bar 47, so that the lowermost staple
on the guide 11, is released and is permitted to be placed in the recess 40 of
the staple carrier.
When the stripper rises, the finger 51, clears the projection 50, and the spring 49,
returns the bar 47, to its normal position, against the legs of the staple on the
guide 11.
Engaging with the segments 34×, are dogs 52, which are pivoted to the column B,
see Figures 1, 2 and 14, and are in contact with a rod N, whose upper end is
pivoted to a lever 53, pivoted to the column B, and connected with link 54, whose

page_text: upper end is pivoted to a lever 543, the latter being mounted on the frame A,
operated by a cam 55, on a gear wheel 56 which latter mounted on the frame A,
meshes with a gear wheel 57, on the driving shaft C.
P desinates a foot lever or treadle, which is pivoted to the vertical rod 58, to which
is pivoted the lever 59, the latter being connected with the arm 60 for operating a
clutch on the main shaft C whereby by depressing the treadle P, the machine may
be started.
Qdesignates a hollow lever, within which is a tooth Q', having its lower end
adapted to engage with a ratchet Q3, on the shaft 34, said tooth and ratchet being
shown in dotted lines Figure 1, and full in Figure 13. The tooth is operated by a
hand lever Q, whereby the shaft 34, may be rotated, thus moving the crank 33, and
arm 32, whereby the wedge J, may be shifted. Owing to the wedge J, the horn H,
may be adjusted to varying thicknesses of the material to be fastened, it being
evident that the position of the wedge beneath the horn regulates or adjusts the
height to which said horn may be set.
The tooth Q, has secured to its side, a pin Q, which projects over one limb of
an elbow Q, whose other limb is in contact with the under side of the pawls 52, so
that when said tooth is operated the pawls are raised clear of the ratchets 34, thus
permitting the shaft 34, to be rotated or rocked, and cause the wedge J, to be
shifted down the incline plane 31. The horn may be lowered by operating a
treadle H', which rests on the foot of the horn, and afterwards elevated by the
spring 30, said treadle being mounted on the column B.
R designates a supply box for containing staples of different sizes from that of
the box E, both boxes being connected with a carriage 61, having a rack bar 61*,
with which engages a pinion 62, having a handle 62, for rotating the same, whereby
the boxes may be shifted, and either box placed in operative position, relatively to
the staple-stripper M, each box containing a wheel D.
The tooth is secured to a plate S2 and is connected by means of screws 63
and 64 which pass through slots in said plate S to the back plate S, one of said
slots being oblique, and the other vertical, so that the proper feeding motions may
be imparted to the teeth, it being noticed that both plates S' S³ may move as one,
so that the tooth may be lowered, while the plate S has an independent motion
on the plate S¹ so as to impart lateral or oscillating motions to said tooth, owing
to the oblique slot through which the screw 64 passes, it being also noticed that
both plates S S are movably connected with a hanger S which is attached to a
proper part of the frame and is slotted for the passage of the screws which connect
the plato S with the back plate S₁ thus permitting both plates to lower as one
and causing the descent of the tooth while the plate S has the lateral or oscillating
motions, as has been stated.
Connected with the upper end of the plate S carrying the tooth, is an arm 65, to
which is pivoted a lever 66, the latter being mounted on the frame A, and adapted
to be engaged by a pin or projection 67 on the rim of the cam 22, see Figures 1, 2,
11 and 12. The cam 29 which rotates with the shaft 28, bears on the head of the
back plate S' of the tooth S, so as to depress the latter and force it into the work,
thus taking hold of the same preparatory to the feeding motion imparted to said
tooth by the arm 65 and lever 66.
Springs are connected with various parts of the machine to return them to their
normal position, and assist them in their operation.
In order to prevent binding of the teeth 7, should they be resisted or clogged,
said teeth are connected with blocks 68, which are pivoted to the wheel D, and held
outwardly by springs 69, so that the blocks are permitted to yield, when the teeth
are subjected to strain, see Figure 3.
The stripper M is formed of sections hinged or pivoted to each other with a
spring 70, bearing inwardly against the upper section, the latter yielding when
subjected to strain and thus being prevented from being injured.
When power is applied to the shaft C, the various parts of the machine are set in
operation.

page_text: A shoo or other article to be stapled is placed on the horn H, and held firmly
against the rest A³, on the frame A. during the operation to which it is to be
subjected.
The wheel or carrier rotates and its teeth 7, are strung with staples which are
carried through the fork 8 and then horizontally over the race-way 10 the teeth then
leaving said race-way, the subsequent staples advancing those in the race-way. The
staples then drop on the guide 11 in upright position and the bar 47 prevents them
from improperly leaving said guide 11.
The stripper M now rises and strips the first staple from the guide 11 and places
the same in the recess 40 of the carrier L. The lever A', which engages with the
carriage G of the carrier L by the rotating-cam 22x now moves the carrier, so that
the staple in the recess 40 is gradually advanced to a position under the staple
driver. Meanwhile the awls have been lowered and they pierce the shoe at the
place to be stapled. The awls now rise, and the staple is fully placed over the shoe
above the openings therein. The carriage G is moved by the cam 22 and the staple
driver having been advanced over the staple, descends and drives the staple into the
shoe, after which the carrier L, returns to its first position.
.
As the horn is made of metal or other hard material, the legs of the staple striking
the same are bent or clinched thus fastening the shoe or article.
The tooth S now lowers and moves inwardly, and as it reaches the shoe, the awls
descend and the tooth takes hold of the shoe and advances it the distance required
after which the tooth returns to its normal position. Owing to the dogs 52, the
ratchets 34 are held in locked position, thus preventing rocking of the shaft 34 and
holding the wedge J during the operation of the machine.
After the staple has been clinched, the cam 38 allows the rod K to drop, thus
releasing the pawl 36 from the ratchet 37, owing to the throw-off 39 thus permitting
the shaft 34 to rotate due to the action of the spring which bears against the wedge,
and the latter adjusts itself to the varying thicknesses of the shoe or material on
the horn.
The shoe is again pierced at a fresh place, and another staple is taken from the
guide 11 located over the shoe, and driven into the same and clinched and
so the operations are repeated until the work is finished, the shoe then being
removed.
