Leather and other Materials.
I, JOHN HENRY RADEY, of Philadelphia, Pennsylvania, United States of America,
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 improvements in machines for inserting and clinching staples
in shoes &c.; and it consists of feeding, retaining, piercing, grasping, and driving
devices, as will be hereinafter fully set forth.
It also consists of means for supplying staples of different lengths and thicknesses
to the feed-chute, and operating the machine without changing the devices for lifting,
piercing, clinching and the like.
In the accompanying drawings,
Figure 1 is a front view of the machine embodying my invention, certain parts
thereof being removed.
Figure 2 is a central vertical section thereof.
Figure 3 is a side elevation of a detached portion.
Figure 4 is a view of a detached portion of Figure 1 partly sectional.
Similar letters of reference indicate corresponding parts in the several figures.
Referring to the drawings, A represents the frame of the machine, and B
represents the driving shaft, which is suitably mounted on standards Bí of said
frame.
(represents a spur-wheel, which is supported on one of the standards B¹ and
geared with a pinion a, which is keyed or otherwise secured to the said shaft B, said
wheel C having secured to or formed with it on one side a cam, C¹, which is adapted to
bear against a sliding carriage D, which is sustained on the frame A beneath the
shaft B the end of said carriage opposite to the cam C¹ being formed into a head,
within which is fitted a vertically arranged staple-driver E, and to the lower end of
which is secured a pair of vertically arranged fingers F, between which the working.
end of the driver E is located, said fingers being sufficiently elastic to receive and hold
a staple inserted from below.
Grepresents the feed-chute of the machine, the same being secured in position

page_text: beneath the head of the slide or carrier D, and extending in an inclined direction, so
that staples placed on the chute will move down the same by gravity to the lowest
point, which is just beneath the fingers F.
H represents a feed-bar, which is passed vertically through the lower part of the
frame A, and guided in an opening in a supply box or cup J, which is supported on
the frame below the carrier D, said bar being attached to a lever K, which is pivoted to
the frame A and connected with an arm K, the upper end of which is fitted on an
eccentric on the shaft B, whereby rising and falling motions are imparted to the bar,
it being noticed that the location of said bar is such that when it is raised to full
extent its upper end is adjacent to the highest part of the feed-chute G (see dotted
lines, Figure 2).
To the frame below the carrier D is connected a horizontally-arranged slide L, from
which depends a stripper M of bifurcated shape, so located that when the bar H is at
its highest point said stripper advances along the same and forces the staple which
rests on the top thereof from its position and places it on the feed-chute G. Motion
in one direction is imparted to the slide L by means of a pin or post N, which passes
vertically through a longitudinal slot b, in the frame A, and a slot 6', in the carrier D,
and is engaged by a lever or arm P, which is pivoted to one of the standards B¹ of
the frame, said arm being operated by a cam Q, which is fixed to the driving-shaft B,
whereby by the rotation of said shaft B the cam Q and arm P force back the slide L, and
consequently the stripper M, ready for the advance motion of said stripper occasioned
by a spring R, which bears against the frame A and slide, or may be otherwise suitably
applied.
S représents a staple-lifting bar whose upper end is bifurcated and so disposed as to
straddle the feed-chute at the lower end thereof, the same being mounted on the
frame A and operated by levers S¹, S", through the medium of an eccentric on the
driving-shaft.
To the box or cup J is pivoted a staple-holder T, which extends parallel with
the lifting-bar S at the side thereof, and has its upper end or nose turned inwardly
toward the feed-chute G at or about the position occupied by the second staple, so that
at a proper time said nose presses said staple, thus holding the same and all other
staples above it, the first or lowermost staple being left free to be removed. The
pressing notion of the staple-holder is occasioned by a swell or cam U, formed on
the side of the lifting-bar S, the lower end of the holder being adapted to come in
contact with said swell or cam, the relieving or returning motion of the holder being
occasioned by a spring U₁, suitably applied.
To the end of the driving-shaft above the staple-driver E is secured a cam V, and
another cam V, which are placed side by side, the cam V being fitted in a yoke W,
which is attached to the upper end of an awl or piercer X, which has two prongs to
form the openings for the legs of the staples, the awl being vertically guided in the
head W', which is mounted on the adjacent part of the frame or bed of the machine,
and adapted to slide thereon in the longitudinal direction thereof as a part or connected
piece of the carrier D.
Attached to the frame W' is a spring-catch d, which is adapted to drop into a
notch in the head or holder of the awl, said catch serving to sustain the awl when
elevated, when the yoke W is relieved of the cam ▼ by the motion of the carrier D,
as will be hereinafter set forth, said catch, however, being overcome when the awl is
depressed.
Y represents a bed or anvil for holding the shoe or other article while the staples
are being driven thereinto and clinched, the same being secured to the frame of the
machine or to the feed-chute, and in either case occupying a position adjacent to the
lower end of the feed-chute.
The box or cup J has a depressed top, so as to direct the staples to the centre over
the feed-bar H. In order to provide means for feeding staples of different sizes, I
employ an additional box or boxes and connect them by a coupling Z, and
fit the boxes to the frame or bed so as to slide in the transverse direction of the
machine.

page_text: Each box or cup has connected to it, as at Z¹, a feed-chute G, and a noder
fting-bar S having a swell or cam U on each side, so as to be engaged by either
older. Furthermore, each box or cup has a connected feed-bar H, and the end of the
ever K under the box or cup has pivoted to it a saddle H¹, which is adapted to have
he lower end of either feed-bar placed upon it, whereby when the lever K is raised
he relative feed-bar will also be raised, it being noticed that the feed-bar is not fixed
o the saddle.
Z represents a lever, which is pivoted to the frame or bed of the machine and
onnected with one of the boxes or cups, whereby the coupled boxes or cups may be
onveniently moved as one and shifted in proper position over the lever K, whereby
he feed-bar may be operated and the desired size of staples raised and presented for
he action of the stripper.
The box or cup is supplied with staples, power applied to the driving-shaft and the

rises and works its way through the staples, taking such by the head or crown as is
n its path and raising it or them to the top of the box or cup. The stripper advances
and clears the bar of the staples and moves them toward and on the feed chute, down
which they ride to full extent. The awl descends and pierces the shoe, and then rises
to its normal position, the catch d then engaging with the awl head or holder. The
which grasp the
lifting-bar S now rises and forces the first staple into the fingers F,
same, the second and remaining staples being stationary, controlled by the holder, as
has been stated. The carrier D then advances and forces ahead of it the awl with its
connected yoke, the latter leaving its cam and remaining suspended by the spring
catch d, and the staple-driver and fingers being placed above the bed or anvil Y, with
the legs of the staple in position to enter the perforations made by the awl.
It will now be seen that the cam V₁ is directly above the head of the staple-driver,
and it is evident that the rotation of said cam depresses the staple-driver, thus forcing
the staple into the shoe or other article, the legs being clinched thereon by the action
of the bed or anvil. The stripper returns to its normal position, the staple-driver rises,
and the head W is carried back, thus restoring the awl, staple-driver, and fingers to
their normal position, the yoke W again encircling the cam V, the return motion of
the head being accomplished by the action of a spring W", suitably applied, or by the

stripper advances, so that the feed-chute is further supplied with staples, the lifting
bar is elevated, the awl pierces the article, and the subsequent operations, similar to
those stated, are repeated.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
First. In a staple-driving machine, a box or cup for staples and a single staple-
feeding bar working up through the same, in combination with the slide L, moving
longitudinally across the top of said cup, a stripper M, carried by said slide, and a
chute to which said stripper delivers the staples after removing them from said staple-
feeding bar, substantially as and for the purpose set forth.
Second. A feed-chute in combination with a pair of elastic fingers arranged to
receive staples therefrom, and a staple-lifting bar which forces them one by one from
said chute into said fingers, substantially as set forth.
.
Third. A pair of elastic fingers, in combination with a staple-lifter which forces each
staple up between said fingers, and a staple-driver operating down through said fingers,
substantially as set forth.
Fourth. A driving-shaft and cam actuated thereby, in combination with a sliding
carriage advanced by said cam, a pair of staple-holding fingers, and a staple-driver
mounted on said carriage, and devices for feeding the staples singly to said fingers, to
be driven substantially as described.
Fifth. The chute, in combination with the staple-holder T and the staple-lifter
formed with a swell or cam V, substantially as and for the purpose set forth.

page_text: Sixth. A carriage D, sliding horizontally and adapted to present the staple-driver
in the position previously occupied by the awl, in combination with the staple-driver
and awl carried by said sliding carriage and driving-shaft, and intermediate mechanism
whereby the foregoing devices are operated.
Seventh. Two or more boxes for holding staples, each provided with a feed-bar
which works through the box, in combination with the chutes G, supplied from said
boxes by the feed-bars, the single-lifter S, which receives the staples from all of said
chutes, and a single staple holding and driving device, substantially as and for the
purpose set forth.
Eighth. Sliding supply boxes or cups, each with a feed-bar, in combination with
an elevating-lever provided with a saddle H¹, adapted to lift either one of two of
said feed-bars when brought into proper position therefor, substantially as and for
the purpose set forth.
Ninth. The carriage D, with slot 6. frame A, with slot b, in combination with
the stripper slide L, the pin N, arm P, and cam Q, substantially as and for the
purpose set forth.
Tenth. The feed-chute staple-lifter, awl, and holding and driving device, in com-
bination with the bed or anvil Y, substantially as and for the purpose set forth.
