SPECIFICATION forming part of Letters Patent N0. 755,099, dated. March 22, 1904.
- Application filed January 24, 1903. Serial No. 140,403. (No model.)
To allwhmn it may concern:
I Be it known that I, CHARLES A. BERTRAND, a
- pose of holding the pieces of leather together with and ride upon the Wedge projections upon the side of the box, and an operatinglever pivotally connected to the clamping-bar.
The invention consists also in certain details of construction hereinafter fully described, and pointed out in the claim.
In the drawings, forming part of this specification, Figure 1 is a perspective view of a holder or clamp constructed in accordance with my invention. Fig. 2 is a top plan view of one end of a device, the lever and clampingbar being moved to an open position ready to receive the pieces of leather to be held or clamped. Fig. 3 is a similar view showing the lever and clamping-bar adjusted to bind against the strips of leather arranged in the box of the holder. Fig. 4 is a transverse sectional view on the line 4 4 of Fig. 3.
In carrying out my invention I employ a long narrow openended'box A, comprising the bottom piece A and the side pieces A said side pieces projecting above the bottom A, as most clearly shown in Fig.4. .The box may be any desired length and width, according to the character of the work to be performed. One of the side pieces A is provided with wedge-shaped projections B, which extend inwardly toward the center of the box, and it will be understood that these projections may be formed integral with the said side or connected thereto in any suitable manner. A clamping-bar C is arranged longitudinally within the box, saidclamping-bar being of substantially the same length as the box, and this clamping-bar is also provided with wedge-shaped projections D, which are adapted to contactwith and ride upon the wedgeshaped projections B whenever the clamping-bar is moved longitudinallywithin the box, and in order to so move the clampingbar I employ a hand-lever E, which is pivoted in a suitable bracket F, attached to the side of the box and pivotally connected to the clamping-bar by means of a link G. The strips of leather H are arranged longitudinally within the box between the clampingbar and the opposite side of the box, and the hand-lever is then thrown forwardly into the position shown in Fig. 3, and the clampingbar being moved longitudinally the inclined or wedge-shaped projections contacting with and riding upon the Wedge-shaped projections upon the side of the box cause the said clamping-bar to be moved toward the opposite side of the box and tightly bind or clamp the strips of leather and securely hold them in that position, and by having theside of the shaped bail K, connected to the clamping-bar adjacent to its free end, and the post or screw K, fastened to the bottom of the box and arranged Within the bail K, said bail contacting with the said screw or post and limiting the movements of the clamping-bars. Whenever narrow strips of leather are to be clamped and held or when the trace is to be held for the purpose of burnishing the edges, a supple- .box and the clamping-bars straight and even mental clamping-bar L is arranged Within the box alongside the main clamping-bar, so that the limited inward movement of the clamping-bar will be sufiicient to tightly bind the strips together.
It will thus be seen that I provide an exceedingly cheap, simple, and efiicient device for clamping and holding strips of leather while being tacked together or While the edges are being burnished.
By making the bail essentially triangular in shape the inclined side contacting with the post will serve to draw the clamping-bar away when the lever is thrown back to open the devlce.
Having thus fully described my invention,
fied.
