Wire Staples for Use in the Manufacture of Boots and Shoes.
I, HORACE E. CUNNINGHAM, of Bridgewater, in the County of Bucks, State of
Pennsylvania, United States of America, Machinist, do hereby declare the nature of
the said 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 consists in providing a stapling machine for attaching welts to soles
of boots, shoes and the like with a guide which is adjustable relatively to the width
of the welt, and the location of the boot, shoe, or the like, to which the welt is to he
secured. It also consists of other novel features as will be hereinafter set forth.
In the accompanying drawing
Figure 1 represents a front elevation of the portion of a machine embodying my
invention.
Figure 2 represents a side elevation thereof.
Figure 3 represents a top or plan view thereof.
Figure 4 represents a vertical section.
Similar letters of reference indicate corresponding parts in the several figures.
A designates a portion of the frame of the machine, B designates a finger which is
pivoted to said frame, so as to feed the welt, said finger receiving oscillating motion
in any suitable manner.
Near the bed or base C, of the portion of the frame A, are guides D, between
which the welt is passed, and in said base is an opening E, through which the staples
are driven into the welt, the staple driver F, being located above said opening and
receiving advancing and returning motions in any suitable manner.
G designates a bead which is located on the under side of the portion A, of the
frame, and connected with a rack H, which is guided on the base of the portion of
the frame, and has meshing with it a pinion J, which as will be seen is secured to
a spindle or shaft K, the latter being suitably mounted on the portion of the frame.
Pivoted or hinged to said portion of the frame is a latch L, or dog, whose nose is
adapted to engage with either of the teeth of a wheel M, the latter being secured to the
spindle K, it being noticed that said dog L, is held in engagement with the wheel M,
by means of a spring N, suitably applied.

page_text: The operation is as follows
The welt is passed through the guidos D, and rested on the head G, and against
the "
upper, "which with the insole, shown most clearly in Figure 2, is supported on
the anvil or horn P.
The staple is located and the driver descends whereby the legs of the staple "pass
through the welt and a proper part of the upper and insole, and their ends are
clinched on the insole owing to contact with the horn or anvil P.
The driver returns or ascends and the finger B is operated whereby the welt is
advanced the distance required for the next staple.
In order to adjust the position of the upper and insole which rests on the horn or
anvil P, and that of the welt, the head G, is moved forwards or backwards as the
case may be, this being accomplished after pressing the latch or dog L, whereby its
nose moves the teeth of the wheel M, and then rotating the spindle K, whereby the
pinion J, which engages with the rack H, is caused to move the head in the proper
direction.
When the adjustment is accomplished, the latch or dog L, is "let go" whereby its
nose drops into engagement with the proper tooth of the wheel M, thus locking said
wheel and consequently the pinion preventing movement or shifting of the head G.
The opening E, has an offset E', which permits tho shoulder on the working end
of the driver F, to descend to the full extent through the opening in the base, and
causes said driver to work effectively in forcing the staple through the different
thicknesses of material and occasioning perfect stapling.
The base C, guides D, bearings of the spindle K and support of the rack H, are
connected with a plate A' which is removably attached to the frame A, so that said
parts may be displaced when so required.
.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :
First. In a stapling machine for attaching welts to soles of boots, shoes and the
like, a guiding head made adjustable on the supporting frame, substantially as
described.
Second. A guiding head connected with a rack bar, a pinion meshing with said
bar, and an operating spindle or shaft connected with said pinion, substantially as
described.
Third. In a stapling machine, substantially as described, a head and an operating
rack and pinion in combination with a dog which locks the shaft of said pinion,
substantially as described.
Fourth. In a stapling machine, substantially as described, a bed or base having an
opening through which the staples are driven, and an offset to opening substantially
as described.
Fifth. In a stapling machine, the adjusting device and connected parts, in combina-
tion with the removable plate A¹ substantially as described.
