IMPROVEMENT IN THE MANUFACTURE OF BOOTS AND SHOES.

Specification forming part of Letters Patent No. 154, [34, dated August 18, 1874; application filed May 13, 1874.

To all whom it may concern:

Be it known that we, THOMAS FEAREY and ALVIN E. OHIOKERING, of the city and county of Albany, State of New York, have invented a new and Improved Mode of Constructing Machine-sewed Boots and Shoes; and we do hereby declare that the following is a description thereof, reference being had to the accompanying drawings, forming a part of this speciiication, in which Figure 1 represents a perspective view of a shoe, illustrating the first stage in the process of construction. of the same, as practiced in our invention. Fig. 2 represents a perspective view of a shoe in the secondstage of its progress of construction as practiced in our invention. Fig. 3 is a cross-sectional view of a section of the inner sole and upper, and the manner of securing the same together, as practiced in our invention. Fig. 4 is a cross sectional view of the same, with the sole secured for the final finish of the shoe.

Our invention relates to that class of boots and shoes known to the trade as machinesewed boots or shoes, in which the soles are secured to their uppers by stitching, either by thread or by wire screws and consists of a machine-soled boot or shoe having its upper overlapping the edge of the inner sole upon its lower or wearing surface, and united thereto by lateral stitches, and its outer sole secured by a line of vertical fastenings passing through its upper and the inner sole; the objects of the invention being to unite the inner sole to the upper in a manner equally as strong and durable-as when stitched by hand, to dispense with the use of tacks or nails in the inner sole, and to produce a machinesewed boot or shoe in which the upper will not part with the inner sole when the outer sole has become worn, as has heretofore been the case.

To enable others skilled in the art to make and use our invention, we will proceed to describe it inreference to the drawings and the letters of reference marked thereon, the same letters indicating like parts.

In the drawings, A represents the uppers,

comprised by the front a and back quarters b.

B, Figs. 1, 3, and 4, is the inner sole. G is the sole proper.

Heretofore it has been the practice of the trade, in machine sewed or pegged soled boots and shoes, to last the inner sole on the last, with the lower border edge a of the uppers drawn over the edge of the inner sole, substantially as shown in Fig. 5, where it was secured by tacks or nails 2:, as shown in the said figure; the upper, where thus secured by a row of tacks, commencing at a point forward of, the shank and running to and round the toe, and a second row commencing at a point back of the shank and running round the heel, leaving, at the entire length of the shank, the upper in loose contact with the inner sole. The outer sole then was placed over the inner sole, and the border edge of the upper turned over the same and stitched vertically through both the outer and inner soles, and the upper between, with the nails or tacks remaining, and with their points projecting through to the inside, when they were turned over and clinched, more or less. It is well known that this practice of constructing the boot or shoe was deficient in the strength of the union of the upper with the inner sole, and that when the threads of the outer sole were worn through the several parts would come apart, and the shoe or boot would become useless; while the points of the nails or tacks would always remain, to he a source of annoyance and discomfort, and a means for discoloring and injuring the soles of the socks or stockings of the wearer.

In our invention, the inner sole is cut with the channel 0, Figs. 1, 3, and 4, which channel is made at a distance from the edge of the said inner sole, in a lateral direction toward the said edge, as shown in Fig. 3. The said inner sole is then placed upon the last, and the upper A is drawn over in the usual manner, with its border edge e overlapping the portion of the inner sole outside the channel 0, as shown in Fig. 3. In this manner the said upper A and the inner sole B are conjoined and secured by stitchings s 8, Figs. 1 and 3, made by a machine, in a lateral direction from the channel 0 outward and throu h the border the shank permanently secured to the same throughout the whole existence of the boot or shoe.

The outer sole 0 is then laid over the inner sole and pinned in the usual manner. The last is then removed, and the said sole, previously channeled, is stitched to the inner sole by wax or other proper thread, or by screw cable-wire or other means, in a manner heretofore practiced by the trade, by the vertical stitching s s, or their equivalents, Figs. 2 and 4, passing down from the base of the channel 0 of the said outer sole to the inside surface of the inner sole, as shown.

It will be readily seen that by this mode of uniting the inner sole to the upper by the lateral stitchings, and securing the outer sole to the same by vertical stitchings, as practiced in our improved mode of construction of machine sewed boots and shoes, the article will be in the quality of its connections of those parts fully equal to the hand-made artisame time the edges of the outer sole will be made to lie close up to the upper in all its parts from toe to heel, and the usual shank portion will be made strong, and the inner surface of the inner sole will be free from all points of nails or tacks, which give discomfort and soil and injure the socks or stockings of the wearer.

Having described our invention, What we claim, and desire to secure by Letters Patent,

A machine-soled boot or shoe, having its upper overlapping the edge of the inner sole upon its lower or wearing surface, and united thereto by lateral stitches, as shown, with the outer sole secured by a line of vertical fastenings passing through upper and the inner sole, substantially as and for the purpose stated.
