STlTCHlNG-HORSE.

SPECIFICATION forming part of Letters Patent N o. 458,104, dated August 18, 1891.

Application filed May 5, 1891.

.To @ZZ whom, it may concern:

My invention relates to improvements in` stitching-horses, and especially to that variety of horses which are adapted for use in harness-making; and the object of my invention is to produce a simple, durable, and efficient device, which may be easily and rapidly operated, and which is adapted to hold large pieces of leather in position while they are being stitched.

To this end my invention consists in a stitching-horse constructed substantially as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specilication, in which similar iigures of reference indicate corresponding parts in all the views.

Figure 1 is an end View of a horse embodying my invention. Fig. 2 is a side elevation of the same, and Fig. 3 is a broken vertical section on the line no :o of Fig. 2.

The horse is provided with a convenient seat 10, of the usual kind, upon which the operator sits, andv this seat is supported upon legs 11 in the ordinary way. On one end of the seat is a clamp 12, which is arranged vert-ically, and which consists of two separable jaws 13 and 14, which are curved inwardly at their upper ends and adapted to impinge upon each other in the usual manner. One of' these jaws 13 is iixed, and the jaw 14 is movable, being hinged to the iixed jaw. The fixed jaw 13 projects downward through the seat 10, is provided with a widened portion 15, which rests in a corresponding recess 16 of the seat, and it is preferably held in position by a key 17, which projects through a slot in the lower end of the jaw and rests against the bottom of the seat. The jaw 14.

is hinged tothe wide portion 15 of the jaw 13, as shown at 1S, and the jaws are normally pressed apart by a iiat spring 19, which is doubled into a U shape, so that its opposite members will press outward upon the jaws, and the spring is held at the center in a keeper 20, as best shown in Fig. 3. A plate Serial No. 391,639. (No model.)

21 is secured to the upper portion of the seat 10 and encircles the clamp 12, and pivoted to ears on opposite sides of this plate are levers 22, which are curved outwardly at the center and which are centrallypivoted, so that their upper and lower ends may swing laterally. The upper ends of these levers terminate in cross-pieces 23, which press against thejaws of the clamp, and one of the levers is secured to the fixed jaw, as shown at 24. rlhe lower ends of the levers extend downward beneath the seat 10, and they are connected together by toggle-levers 25, which at their center joint are provided with a depending hook 26, to which is secured the upper end of a strap 27. A suitable guide 2S is supported transversely between the legs of the horse, and into this The strap 27 also extends downward through the guide 28 and its lower end is secured to a lever 29. This lever extends transversely beneath the lower portion of the horse and is adapted to be operated by the foot. The inner end of the lever is secured to a round 30, which round is pivoted in the legs of the horse, as shown in dotted lines in Fig. 1.

Near one of the legs of the horse the lever 20 is provided with a projecting plate 31, which plate is Secured to the lever and is adapted to engage the teeth 32 of a plate 33,

and when the lever is depressed it may be swung so that the plate 31 will engage one of the teeth on the plate 33, and the lever will thus be held in position.

The operation of the device is as follows: The operator sits upon the seat 10, places his pieces of leather between the jaws 'of the clamp 12 in the usual manner, and then presses downward on the treadle-lever 29 with his foot. This depresses the inner ends of the toggle-levers 25 and throws outward-fthe lower ends of the levers 22,A and the upper ends of the levers are thus forced together and press the jaws of the clamp firmly upon the leather. The lever 29 is held in place by locking the plate 31 into onel of the teeth 32, as described, and the jaws will thus be held in position upon the leather. It will be noticed that the levers 22 press evenly upon both sides of the clamp, and the lever conwhich plate is secured to an adjacent leg,

guide the lower ends of the levers 22 extend.

IOO

nected with the fixed jaw thus serves as a brace and prevents the displacement of the clamp.

Having thus fully described my invention, I claim as ner and desire to secure by Letters Patent- 1. A horse of the character described, cornprising a seat, a clamp mounted upon the seat, levers centrally pivoted to the seat and having their upper ends arranged to press against the jaws of the clamp, and a treadle mechanism for operating the levers, substantia-ily as described.

2. A device of the character described, coinprising a seat, a clamp secured thereon, levers pivoted on opposite sides of the seat and having their upper ends arranged to press against the clamp, toggle-levers connectingthe lower HENRY J. ELSKAMP.
