Improvements in Stitching-horses.
I, HERMAN DOERING, Manufacturer, residing at Reedsburg, in the County of
Sauk, and State of Wisconsin, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
scertained in and by the following statement :-
Figure 1, represents a side elevation of a stitching-horse embodying my invention.
Figure 2, is an end view of the same.
Figure 3, is a detail to be referred to.
My invention relates to the class of machines for stitching leather articles, such as
harness, and commonly known to the trade as "stitching-horses;" and my invention
consists of the construction and combination of devices which I shall hereinafter
fully describe and claim.
To enable others skilled in the art to which my invention appertains to make and
use the same, I will now describe its construction and indicate the manner in which
the same is carried out.
In the said drawings, A. represents a suitable frame-work comprising the
supporting-legs a, the operator's seat b, and a rock shaft c, to which the operating
foot-lever d is secured.
In the seat portion & is formed an opening e through which passes a rope, chain,
or other connection f, whose upper end is secured to the movable jaw of the device
and whose lower end is secured to the lever, so that when the foot-lever is depressed
the connection acts upon the movable jaw to cause it to approach the fixed jaw.
The jaws B and C, between whose gripping edges the material is passed, are of
peculiar construction, and each is formed with a curved upper portion or head, whose
meeting edges are beveled to insure a tight grip upon the piece of leather or article
placed between them. The jaw B is the fixed jaw, and is formed with integral
arms E, extending downward in vertical planes parallel with each other. These
arins E form the bifurcated standard, and upon which the jaws are supported and
whose lower end is formed with a horizontal base-plate E', which rigidly unites the
two jaws and forms a base or stand, by which the device is secured to the seat
portion of the main frame.
In order that the standard and the jaws may be readily detached from the main
frame and raised to higher elevations when desired by the introduction beneath the
base-plate of a block, I form the said base-plate with feet g, having slots h, (see
Figure 3) through which and the seat portion of the frame bolts are passed. This
construction enables me to adjust the height of the jaws to suit the operator.
Near the junction of the separated arms or standard with the curved jaw portion
hubs or bosses m are formed to receive the pin or bolt n, which serves to unite the
fixed jaw with its companion movable jaw and forms the pivot about which the
latter jaw moves.
The movable jaw has its curved portion formed like the similar portion of the
fixed jaw, and it has a single-arm extension L, which is adapted to pass through

page_text: and play between the bifurcated standard of the fixed jaw, said movable jaw having
a hub portion, through which the pivot bolt or pin n passes. At the lower end of
the movable jaw C an eyes is formed for the securing of one end of the rope or
chain connection f, and within the lower portion of the bifurcation of the fixed
standard is mounted a roller t, over which the connection passes to the foot-lever.
In order that the jaws may be forced apart after the foot-lever is released, I
employ a spring H of peculiar form, and locate this spring between the fixed
bifurcated standard and the arm L of the movable jaw at a point just below the
point of pivotal connection of the two jaws. This spring H is made of a single piece
of heavy spring wire bent upon itself to form a foot or bearing u, and then the ends
are carried upwardly and form the coils !, after which the ends are bent down-
wardly along the rear side of the arms of the fixed standard and their extremities
fitted in openings w in said arms. This construction and disposition of the spring
keeps the jaws normally open, but yields to permit their closing when the foot-lever
is depressed.
From this description it will be seen that the present invention is very simple
and effective in its operation. The fixed jaw is integral with its slotted standard
and the movable jaw has its integral arm adapted to enter the bifurcation of the
standard of the fixed jaw, so that it takes up no great amount of room. Nothing in
the structure is liable to derangement, and the whole device above the seat-frame is
made of but three essential parts, which, with the exception of the spring, may be
cast to cheapen the cost of manufacture.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that
what I claim is
1st. A stitching-horse comprising a fixed jaw having an integral bifurcated
standard detachably secured to a main frame, a roller within the lower portion of
said bifurcation, a movable jaw pivotally secured in the upper portion of the
bifurcation and having a single arm extending through the latter, a spring for
actuating the movable jaw, and a flexible connection extending from the lower end
of said arın over said roller to the power device, substantially as herein described.
2nd. In a stitching-horse, the main frame and operating foot-lever, the fixed jaw
having an integral bifurcated standard, a base-plate integral with the standard and
provided with slotted foot portions, bolts detachably uniting the standard with the
main frame, a movable jaw pivotally held within the bifurcation of the standard
and having a lever-arm extension, a spring for holding the jaws open, a guide-roller
in the base of the standard and a flexible connection secured at one end to the arm
of the movable jaw, passing over said roller, and having its opposite end secured to
the foot-lever, substantially as herein described.
