IMPROVEMENT IN MACHINE-MADE STITCH.

Specification forming part of Letters Patent No. 85,891, dated January 12, 1869.

To all whom fit may concern: Y

Be it known that I, T. K. REED, of East Bridgewater, in the county of Plymouth and State of Massachusetts, have invented an Improvement in Fastening Sewing-Machine Stitches; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specication, is a description of myinvention sufficient to enable those skilled in the art to practice it.

The invention relates to a new method of securing sewing-machine stitches, so as to render them stronger, less 4liable to be worn through by abrasion, and more easily made, the invention being intended particularly for sewing with waxed thread, and being particularly applicable to such sewing.

The invention consists in securing successive stitches by short pieces of wire or other material inserted into the loops thereof, each loop being drawn up against the wire by the stitch-forming mechanism, and being held by the wire or other device.

The drawing represents, at A, a View of a small portion of the under surface of a piece of stock stitched in accordance with my improvement.

a. denotes the stock; b b, the stitches of thread. These stitches, instead of being interlooped one with the other (with the same or with a second thread,) are simply passed through the stock, and left without interlooping, as seen at A B. Into the bow of each stitch (as it is formed) a short piece of wire, e, or other suitable material, is thrust, this wire occupying the position, with respect to to the bow, as seen in the section at O, and lying` across the stitch, as seen at A.

I prefer to make the stitch-fastenings of wire, bent into the form shown at G and in the detail D, and to lay them at an inclination to the seam, as shown at A; but it will be obvious that they may be made of straight pieces of wire, or of other material, and that the pieces may be laid at right angles with the seam, instead of at an inclination thereto.

The fastening is inserted when the bow of the stitch is open below the work, (or on the side opposite to that from which the thread is supplied,) and after insertion the stitch is drawn tightly into or against the work, embedding the fastening into the surface thereof', so that it is kept from slipping or Working out; and where the wire is bent as shown the bow in the wire permits the thread to be drawn into the surface of the work, making a very smooth seam. y

By this means the stitches are made very secure, very much less thread is required than where the stitches are interlooped or interlocked, and as each stitch on the fasteningsurface is directly independent of the next one, the stock is much more yielding or pliable in the direction of the length of the seam than where sewed in the ordinary manner.

My improved seam may be made with rapidity on a machine for which I have an application for a patent now pending in the United States Patent Office, filed October 28, 1868.

I claim- A machine-sewed seam having its stitches formed of a continuous thread, each loop of which is fastened by a shortbolt of wire, substantially as described.

T. K. REED.
