SPECIFICATION forming part of Letters Patent No. 4 29,4so, dated June 3, 1890.

Application filed September 13, 1889. Serial No. 323.820. (No model.)

To all whom it may concern:

Be it known' that we, FREDERICK B. ROBIN- SON and WILLIAM J. MORGAN, of the city of Rochester, county of Monroe, and State of New York, have invented certain new and useful Improvements in Insoles; and we do hereby declare the following to be a full, clear, and

exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to figures of reference marked thereon.

Heretofore numerous attempts have been made to provide insoles for shoes that were flexible and cheap, and some of these have been more or less successful; but they have, in the main, been constructed either of whole stock or of scraps softened and molded into sheets and then the insoles cut from them, and while otherwise worthless Scraps have been utilized in the latter operation the formation of the sheets of composite stock has cost.

considerable, and the waste from these sheets has in turn to be utilized, and from the manner in which solid insoles are cut the scraps are of such shape as to leave considerable waste from each sheet. Another fact that seemingly has escaped the attention of inventors in the art to which our present invention relates is that the principal function of an insole is to hold the edges of the upper during the operation of lasting and while the outer sole is being sewed on, and that after these Operations are accomplished, and particularly with ladies light shoes, a thick insole is uncomfortable. Consequently the lighter the insole consistent with the requisite strength to hold the parts during the sewing the more advantageous it is,both on the ground of economy in the manufacture and ease of the wearer.

With the object in view, therefore, of providing an insole not only cheap to make, being capable of being made of otherwise waste material, but also one possessing in the highest degree pliability and ease to the Wearer, our present invention consists in a certain improved construction hereinafter described, the novel features being pointed out in the claims at the end of this specification.

In the drawings, Figure 1 is a plan View of the side of the insole lying next the outer shoe-sole Fig. 2, a longitudinal s'ectional View on'the line x x, and Fig. 3-a transverse sectional View of the same on the line y y, of Fig. 1.

Similar numerals of reference in the several figures indicate similar parts.

In carrying out our invention we form the heel portion of ordinary whole or of composite stock, preferably cut into the final or nearly the final shape, and skive down ts 1nner end or part Where the forward or sole proper joins it.

The forward or sole proper is composed of two parts, the lower part 2 (in the drawngs) being composed of some strong preferably teXtile materialsuch as drilling or duckcut into proper or approxinately proper shape, and the upper part 3 of a strip of leather preferably skived down thin on one side and bent around into the proper shape, its outer side being substantially even with that of part 2 and secured thereto by means of glue or cement placed between the parts. After the parts 2 and 3 are secured together, the latter conforming to the shape of the insole to be formed, the ends of the part 3 may be skived off slightly and the sole united to the heel portion by a line or lines of stitches 4; or, f desired, the parts could be cemented together at this point. The insole now formed can, f desired or necessary, be trimmed by suitable dies, and thus brought into final shape ready for use.

In using this insole it is preferably placed with the face 2 upon the last. The edges of the upper are drawn over and secured to the strip 3 by lasting-tacks or cement, the outer sole applied and sewed on as ordinarily, the stitches passing through the outer sole and strip 3, as usual. This strip 3 forms a good holding grou nd for the stitches and prevents their pulling through, as is the function of all 1nsoles of this description; but our improved form does not have a thick piece of leather extending through the shoe from side to side, increasing the weight and at the same time the stiffness of the Shoe, as only a thin piece of drilling connects the strip 3 at the center, and while it may be desirable in some forms of shoes to have a thick insole it is not in ladies light ones, for which our present inven- IOO ton is especially designed. The drillin g 2 merely forms the means for holding the strip 3 in position until properly Secured by sewing the shoe and is designed for this purpose, though it will be understood that it could, if desired, be made of Water-proof material, and thereby prevent noisture soaking np.

The strip 3 may be formed into proper shape in any suitable inauner either by soaking a strip in Water and holding it in suitable dies under pressure until dried and then applied to part 2, or it may be formed around the part 2 by suitable tacks after the nanner of applyin g welts to shoes. The strips before forming being preferably straight can be cut from Scraps or fron stock made froni sera-ps, or, if desired, good stock, With great economy.

The herein-described insole, as has been determined by actual use, is adnirably adapted for the purpose, the shoes in the manufacture of which it has been employed being easy &29,480
