IMPROVEMENT IN HlDE-STRETCHING FRAMES.

Specification forming part of Letters Patent No. 154,073, dated August 11, 1874; application filed June 27, 1874.

To all whom it may concern:

Be it known that I, CHARLES P. OLIVER, of Newark, in the county of Essex and State of New Jersey, have invented'a new and. valuable Improvement in Hide-Stretchers and 1 do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of a front elevation of my hide-stretcher, and Fig. 2 is a sectional view. Fig. 3 is a detail view, and Fig. 4. is a sectional detail view.

This invention has for its object the improvement of frames which are designed for stretching hides. It consists, mainly, in a stretching-bar, which is independently movable in a direction with the length of the frame, as well as breadthwise; also, in the employment of a rigid Slotted bar, through which the hides are passed, and in which their backs are protected While being stretched; also, in the employment of a jointed lever, which is separable from theframe, and which is used in connection with perforations in the frame-bars for stretching the hides at different points; also, in slotted bars, in combina tion with wedges for holding the hides under Strain, and aiding in the stretching operation, all as will be hereinafter explained.

The frame represented in the annexed drawings is of rectangular form, and is composed of two strong bars, A A, rigidly secured to end guide-bars B B B B which latter may be of wood or of metal. The bar A is slotted longitudinally, so as to form the rounded portion a, over which the hide is drawn, and a covering portion, a, which will protect the leather, where it passes over portion a, from injury. 0 designates the Stretching bar, which is slotted to receive the bars B B B B through it, and to allow it free endwise movement, as well as breadthwise movement, toward and from the slotted bar A.

The'object of giving the stretching-bar G endwise movement is to prevent its binding against the bars B B B B when the hide is being stretched. If such an endwise movement were not given to this stretching-bar G,

Y a transverse portion of a hide of greater thickness than the rest would cause the inner walls of the slots in the bar 0 to be drawn against the said cross-bars, causing great friction of the parts, and adding materially to the effort necessary for Stretching a hide. Endwise motion, however, allowed to the Said stretching-bar will not only secure an easy sliding of the said bar 0 upon the cross'bars B B B B, but will also secure an even stretching of the hide, while at the same time it prevents the formation of ridges upon it.

D D designate two joints, forming a toggle, one of which is pivoted to the bar B and the other plays freely in a slot made through the stretching-bar O. This latter jointis connected, by bars E, to the bar B through one of which bars, E, a hole, I), is made to receive one of two studs, 0, fixed into a toggle-lever, F, the other one of which studs is applied in a hole, b, made in the stretching-bar C. It is by means of lever F that the joints D D are moved for stretching the shoulder and neck parts of the hide, which parts are tacked to said joints. The bars A and C have holes 0 e in their extremities to receive the studs 0 c on lever F, for the purpose of allowing this lever to be used for moving the stretching-bar.

For the purpose of retaining the stretchingbar in the desired places, and keeping the hides under strain, I employ wedges g, which are forcibly inserted through oblong holes made through the bars B B, which holes f are arranged in rows alongside of each other, as

shown in Fig. 1, the arrangement of the holes being such that a wedge can be inserted in one or the other of them at any point during the stretching operation. The wedges, when forcibly struck, will also move the bar 0 and stretch the hide without the application of combination with bars B and B substantially as and for the purpose set forth.

2. The rigid slotted bar A, combined with the adjustable stretching-bar O, substantially as described.

3. The lever F, composed of two jointed parts, h h, and constructed with studs 0 c, as and for the purposes described.

4. The bars B B B having oblong slots through them, in combination with movable wedges g g, and the stretching-bar 0, substantially as described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
