FREDERICK GLOSS, OF NEW HAVEN, CONNECTICUT.

BOOTS, &G.

.To (tZZ whom it may concern.-

Be it known that I, FREDERICK GLoss, of the city and county of New Haven, and State of Connecticut, have invented a new and useful Improvement in Attaching the Soles to the Uppers of Boots, Ste.; and I do hereby declare that tne following'is a full, clear, and exact description ofthe construction, character, and operation of the same, reference being had to the accompanying draw-ings, which make part of this specification, in which- Figure l is a perspective view of a boot made complete, showing the whole appearalice of the sole and upper, with no appearance ot' stitches, channeling, or similar means. Fig. 2 is a perspective view of a portion of the work as viewed from the inner side, showing the position of the stitches on the inner side of the inner sole. Fig. Bis a cross-sec tion of the boot enlarged, showing the stitch as closely drawn at the left-hand and as left considerably loose, to show the nature of the stitch, which is sewed from outside to inside through a small pellicle or sliver of the upper corner of the outer sole, the upper leather, and the. inner sole.

My improvement consists in sewing the soles ot boots or shoes (with proper machin-- ery, which will be explained when a proper model is prepared) to the uppers from outside to inside of the article, and yet leaving the outer sole to be worn oi' to the last pellicle or fragment which can hang together before the wear can come in contact with the stitches which secure the outer sole to the boot, (and the same may be practiced for double soles, Sac., it' desired.) This obviates aprominent objection to machines, because in the common way of sewing by machinery the holes are made so large that as soon as the stitches are wornoit the soles will drop oli' by slight jarring; but when, as in mine, the stitches can not receive any wear, the soles must remain iirmly and secure in their places until the soles are entirely worn out, as` nothing can affect them. I split up a small portion or pellicle of the upper corner of the outer sole allround the foot, as shown at a b, Fig. 3,

and also at a., Fig. 2. I last the uppers over the inner sole in the ordinary way, so that when I put on the outer sole the edge of the upper will be between the inner soie and the split-up pellicle -or sliver a b, the whole, as indicated in Fig. 3. Ill/'hen the parts (soles and uppers) are thus fitted and arranged, l put the machine in motion, when the sewing will be accomplished (by the proper functions of my machine) from the inside to the outside through the inner sole, c d., uppers f g, and through the pellet or sliver a b, which may rst'appear open, as at b d, Fig. 3, but which the machine will immediately close, as represented 1n cross-section at a, Fig. and inper-AA spective at a, Fig. 2, where one stitch, e, is un'- covered and the same character i'or the inside ot' the whole length of Fig. 2. In the outer portion of this stitch-thatis, atc b--thepellet or sliver is drawn up so far that no part of the threadcomes down as low as the upper surface of the outer sole, as is rendered perfectly apparent at a, Figs. 2 and 3, and when the boot is finished no stitch will be seen about its sole.

I can in,this`way and by these means make as durable or serviceable a boot by machinery as can be made by hand, for neither can ever I'ailuntil after the stitches wear ofi,

and by my method it is impossible that the stitches should wear at all until the whole of the outer sole is worn off, as before shown.

WhatI claim as my invention, anddesire to secure by Letters Patent, 1s-.

Sewing (by machinery) the soles to vthe uppers of boots and shoes, substantially as herein described.

F. GLOSS.
