v MANUFACTURE OF SHOES v I Original Filed July ,15, 1932 Patented July 23, 1935 UNITED STATES 2,908,697 MANUFACTURE OF SHOES George Goddu, deceased, late of Winchester,

Mass., by Isabelle W. Goddu, executrix, Winchester, Mass, assignor to The Littleway Process Company, Boston, Mass, a corporation of Massachusetts I Original application July 15, 1932, Serial No. 622,691. Divided and this application October 11, 1933, Serial No. 693,174

Claims.

This invention relates to improvements in shoes and particularly to the securing of shank pieces in shoe bottoms other than by driven metallic fastenings.

The present application is a division of a copending application Serial No. 622,691, filed July 15, 1932, which is directed to improvements in the manufacture of shoes. It is an object of the invention of said application to provide a method of manufacturing shoes such that the heel seat portion as well as the shank and forepart may be lasted, the outsole attached to the heel seat, and the heel attached without the presence in the finished shoe of metallic or other driven fastenings. As an aid to the attainment of that object, the shank stiifener of the shoe, as disclosed in said application and as illustrated and claimed herein, instead of being secured to the insole by a tack or tacks in accordance with usual practice, has its rear end held by a filler piece secured to the heel seat portion of the shoe. This filler piece, which may be made, for example, of hard fibre board, is preferably approximately U-shaped in outline to conform to and be received within the area bounded by the edge of the over-lasted portion of the shoe upper at the heel seat of the shoe. As illustrated herein, it is secured by cement to the insole of the shoe, with the rear end of the shank piece received in a recess formed in the forward end of the filler piece. Thus the shank piece is held securely in place in the shoe without the presence of' metallic fastenings.

With the above and other objects in view the invention will now be described with respect to the accompanying drawing and pointed out in the claims.

In the drawing,

Fig. 1 is a perspective view of a shoe illustrating the condition of its bottom after it has been lasted, with a metal shank piece the rear end of which projects under a filler piece in accordance with the invention, tacks being shown to hold the filler piece in place while the cement,

by which it will be permanently held, is setting;

Fig. 2 is a perspective View of the filler piece on a larger scale; and I Fig. 3 is a perspective view partly in section of the shoe after its sole has been attached, showing the manner in which the shank piece is secured in place by the filler piece.

The shoe in of the drawing isv illustrated as comprising an insole l2, an upper M and an outsole IS, the shoe as shown in Fig. 1 having been lasted and the marginal portion l8 of its upper prepared for the attachment of its sole in the manner disclosed in said parent application Serial No. 622,691.

In order to secure the usual metal shank stiffener 84 (Figs. 1 and 3) without the presence of metallic fastenings and at the same time to fill up the U-shaped space inwardly of the overlasted marginal portion of the shoe upper at the heel seat portion of the shoe, a filler piece 86 is provided. This may be of hard fibreor other suitable non-metallic material having an approximately U-shaped outline, shown in Figs. 1 and 2, to conform to the space within which it is to be received and molded or otherwise shaped to provide a recess or depression 88 at its forward portion for the reception of the rear end of the shank piece 84. Pyroxylin cement, which has previously been applied at the heel seat portion of the insole and permitted to dry, is activated with a suitable softener, for example such a softener as that disclosed in Letters Patent of the United States Nos. 1,959,320 and 1,959,321, both granted May 15, 1934, on applications filed in the name of Walter H. Wedger. The insole engaging surface of the filler piece 86 is also coated with pyroxylin cement and the filler piece is secured in position, covering and holding the rear end of the shank piece 84, by tacks 90 which are preferably toed inwardly the better to hold 7 leaving the shank stiffener 84 secured solely by cement.

If the sole of the shoe is to be cement attached, the exposed surface of the filler piece may be coated with pyroxylin cement which is allowed to dry and the outsole i6 cement-attached in known fashion, any suitable filler being used at the forepart of the shoe, as may be desired. It will thus be seen that the finished shoe is free from metallic shank piece attaching fastenings.

While the invention of this application was developed for and is particularly desirable in connection with the manufacture of shoes the bottoms of which are free from metallic fastenings, it should be understood that its utility is in no way limited to use in connection with shoes of that type since obviously, if desired, shank pieces may be attached in accordance with the present invention in the manufacture of other types of shoes. I

l-lavlng thus described the invention what is claimed as new and desired to be secured by Letters Patent of the United States is:

l. A shoe having a shank stiifener with its rear end retained in a depression molded in a nonmetallic filler piece secured by cement in the heel seat portion of the shoe.

2. A shoe having an insole, an outsole, and a shoe bottom part located between the insole and outsole, said part being formed with a recess, and a shank stiffener having an end portion located in said recess and secured therein by cement.

3. A shoe having a shank stiffener with its rear end retained without the aid of metallic fastenings in a recess formed in a non-metallic filler piece secured by cement to the heel seat portion of the insole of the shoe.

4. A shoe having a shank stiffener the rear end of which is received in a recess formed at the forward end of a filler piece secured by cement to both the insole and the outsole of a shoe at the heel seat portion thereof and within the area bounded by the edge of the overlasted marginal portion of the shoe upper.

5. A shoe having a shank stiffener the rear end of which is received in a recess formed in the insole engaging surface of a filler piece secured by cement to both the insole and the outsole of the shoe at the heel seat portion thereof and within the area bounded by the edge of the overlasted marginal portion of the shoe upper.
