CONNECTING TWO OR MORE PIECES OF LEATHER TOGETHER.

Specification forming part of Letters Patent No. 43,236, dated June 21, 1864.

.To all whom it may concern:

Be it known that I, BENJAMIN F. STURTE- VANT. a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented a new mode of uniting or connecting two or more pieces of leather; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Fig'ure 1 denotes atop view, and Fig. 2 a

'longitudinal section, of my invention as applied to two pieces of leather.

The nature of my invention is a combination consisting of a line of sewing or a series ot'loops or stitches and a series of pegs, or their equivalents, arranged or applied together and within the pieces of leather or material tobe connected, substantially in manner as hereinafter explained, the pegs and loops or stitches co operating so as not only tofasten together the two pieces or sheets of leather or material, but to mutually aid in keeping each otl er in place therein.

In the drawings, A and B denote the said two sheets or piecesof leather, one of which is laid directly upon the other.

(J is the thread, which is formed-in a series ot' stitches or loops, a an a, which are to be successively or otherwise inserted within awlholes made through or in the two pieces of leather. In connection with the series of stitches or loops so applied to the pieces A B, there is to be a peg, wedge, or binder, I

driven into'each of the loop-holes of the thread (J, and in such-manner as with the loop of such hole to completely fill the hole and either expand or compress the loop or portions therein, so as to firmly fasten or fix or aid infirmly fastening or fixing such loop within such hole.

. The loop may be formed by the act ofjforcing the peg into the material or pieces of leather and against the thread previously suitably laid over the mouth of the hole, in which case the peg should be so formed as to insure the introduction of the thread into the hole, or, instead thereof, the loop may be first inserted within the awl-hole by a proper instrument, the peg being subsequently driven into the hole, and either within the loop or alongside of it. There are various other ways in which the thread may beint-roduced nto or secured relatively to the awl-holes.-

The loops may be chain-stitched together if desirable.

In sewing leather bymeansof a sewingmachine and with a thread by running or passing such thread through, or looping it into awl-holes made within such leather, the portion or part of the thread that may come or be deposited within each hole seldom fills the hole. By driving a peg made of wood orother suitable material within the hole, and either alongside of or into the loop, so as to firmly press the loop against the side or sides of the hole, important advantages may be gained as well with reference to the connection of the two pieces of leather as to the securing of the thread or loops in place therein.

We not only have in connection the advantages which appertain to sewing and peggin g when separately considered, but wehave by combination ofthem in the manner as explained the additional advantage of each being made to operate to aid in holding or fixing the other in place within the work-that is to say,-the looped or sewed thread performs its peculiar function of connecting the two pieces of material or leather, and while the pegs in their way answer a like purpose, the thread and the pegs co-operate in such manner that each serves to morev or less sustain or support the other in place, and thus to give additional strength to the connection, and more or less prevent wear of the thread under ordinary circumstances.

In waxed-thread sewing, when the exposed parts of the loops become worn out, the portions of leather held in connection are veryapt to rip or can be readily ripped apart, but with my mode of connection or combination and arrangement of sewing and pegging the pegs will operate to prevent the separated parts of the thread from being easily drawn out of their holes.

I do not claim either pegging or sew-ing when separately considered as a means of connection.

I claim as my invention-- Mynew or improved art, substantially asdescribed, of uniting .or connecting two or more pieces of leather.
