UNITED STATES PATENT OFFICE.

B. F. STURTEVAN'I, OF SKOWHEGAN, MAINE, ASSIGNOR TO ELMER TOWNSEND.

LASTING-PINCERS.

Specification of Letters Patent No. 18,427, dated October 13, 1857.

To all whom t may concern.'

Be it known that I, B. F. STURTEVANT, of Skowhegan, in the county of Somerset and State of Maine, have invented certain new and useful Improvements in Pincers for Lasting Boots, of which the following is a full, clear, and eXact description, reference being had to the accompanying drawings, making part of this specification, in which- Figures 1, 2 and 3 are views of a pair of pincers; Fig. l details to be referred to.

My present invention consists in certain improvements in the construction of lasting pincers, by which I am enabled to produce an article equally ellicient while cheaper and less complicated than the pincers for which I obtained Letters Patent of the United States, dated October 7, 1856.

Thatothers skilled in the art may understand and use my invention I will proceed to describe the manner in which I have carried it out.

In Fig. 4: is shown one branch or lever A of the pincers detached, the upper end is finished in a claw #1, another claw #2 is provided at a and plays in a recess b formed in the broad part of the branch A. The branch B Figs. 2 and 3 is furnished with similar claws 1 and 2 pivoted together at c; a recess similar to that at b is also formed in this branch. The short arms or claws :rl-,1:2 of the two branches are pivoted together at f. This manner of placing the short arms in the recesses Z) allows the inner surfaces of the branches A and B to play in contact with each other.

The way in which the parts are put together is as follows: The two short arms #2 are riveted together and vibrate at f;

they are then placed in their respective recesses I) and one is riveted to the branch A at a, and the other to the branch B at c as seen at Figs. 2 and 3.

The operation is as follows: The handles are spread apart as in Fig. 2 at the same time that the broad part of each branch is caused to slide along the other branch a short distance, which causes the jaws 1 and 2 to separate as in Fig. 2 ready to clasp the leather to draw it over the last; when by drawing the handles toward each other, and sliding one branch on the other the jaws will be closed as in Fig. 3, and the two edges of the leather be drawn toward each other ready to fasten to the last, in which position the operator may hold it with one hand, while he drives the nails with the other. A little practice enabling him to spread the pincers and open the jaws at the same time by a single movement of the handles.

It is evident from the simple form and few number of the pieces composing these pincers that they can be constructed at a much less cost, while they are less liable to be broken or strained than are those described in the above referred to Letters Patent.

That I claim as my invention and desire to secure by Letters Patent is- The above described compound pincers for lasting boots, constructed and operating in the manner substantially as set forth.

B. F. STURTEVANT.
