Specification of Letters Patent.

Patented Mar. 7, 1916.

Application filed October 19,1914.- Serial No. 867,269.

To all 'whom it may concern: i

Be it known ,that I, JAMES W. ARTHUR, a citizen of the United States, residing at Warren, in the county of Trumbull. and State of Ohio, have invented a new and useful Improvement in Methods of Repairtion, reference being had to the accompanying drawings, forming part of this specification, in which Figure l is a view partly in side elevation and partly in vertical section and illustrating a portion of the method; Fig. 2 is a perspective view of, a metal fcrmer blank employed 'in connection with the method; Fig. 3 is a vertical section illustrating the method as applied to the heel of a boot or shoe; and Fig. 4f is a perspective view of the shaped metal former for heel work.

My invention has relation to a novel method of repairing rubber boots and shoes, and particularly, the soles and heel portions thereof.

The object of my invention is to provide a` novel, simple, inexpensive and eiiicient method by which a new sole or heel or partially new sole or heel can be formed on an old boot or shoe.

My invention also provides .means of simple and etcient character whereby the sole or heel may be inished with a rolled edge substantially the same in appearance as thatof a new boot or shoe, and also by which any desired surface configuration can be given the sole or heel, or that conguration may be replaced on rubber shoes after they have been worn smooth.

In accordance with my invention, I provide a suitably shaped sole piece 2 or heel piece 3 of the usual rubber or rubber nia-1i7 terial used in the formation of the soles and heels of rubber boots and shoes. The boot or shoe tobe repaired is placed on the anvilaof a suitable vise 5, in which it can be clamped by means of the screw 6, carrying a suitable clamping plate 7 at its lower end. The piece 2 or 3 is placed on the sole or heel of the boot or shoe in the manner shown in Figs. l and 3. I next place upon the piece 2 or 3 the metal former blank of bendable metalpreferably sheet lead. The initial form Ofthis blank for the sole of a boot or shoe is shown at 8 in Fig. 2, while the final form-of the blank for heel irork' is shown at 9 in Fig. 4. This blank is sufciently larger than the piece to be applied to the sole or heel to leave a surrounding flange portion 10. Thr parts as thus asl sembled are then firmly clamped together by means of the screw 6, and vby means of a hammer or other suitable tool, the projecting edge flanges l0 of the former blank are turned over and downwardly against .the edges of the piece 2 or 3, and against the lower portion of the boot or shoe upper in the manner clearly shown in Fig. 3. The forming surface of the metal blank can be serrated or corrugated so as to impart any desired configuration therein to the bottom surfaceof the sole or heel and also to the 'rolled edges thereof.

After the former 8 or 9 has been properly tshaped over the work in-the manner just described, the boot or shoe is removed from the vise, and the parts are then clamped in any suitable holder and are taken to a vulcanizing apparatus and vulcanized in any usual or suitable way. The former remains in position during the vulcanizing and when removed at the completion of the vulcanizinr operation, it leaves'a perfectly formed sole or heel with a turned and rolled edge of neat and Iinished appearance subsisantially equal to that of a new boot or sice.

It will be readily understood that my invention is susceptible' of many modifications in the character of the apparatus employed; that the shape of the former can be changed to suit any particular job of work, and that the method is adapted to applying patches to other parts of a boot or The method is extremely simple and can be carried out at a comparatively small eX- pense and without very much manual skill. The metal blanks employed for the formers being made of lead or similar soft' metal can be very readily and easily shaped to the work, and after being used can be readily iattened out for use again in subsequent work. to be done in a thorough and finished manner not heretofore possible.

It will also-be understood that my invention may be applied to the repair and vulcanization of other rubber articles.
