To all whom it may concern:

Be it known that I, MARIUS SoRnNsnN, manufacturer of boots and shoes, a citizen of the Kingdom of Denmark, residing at No. 39 Blaagaardsgade, Copenhagen, Denmark, have invented certain new and useful Improvements in Methods of Lasting Boots and Shoes, of which the following is a specification.

This invention refers to a method for wholly or partially lasting boots and shoes by means of a wire loop as lasting-means,

the ends of the wire-loop being fastened at.

the top of the last after the lasting is accomplished. The invention is characterized by the use of a wire-loop as lasting-means, to substitute the work usually done by means of pincers, the ends of the wire-loop crossing each other on the bottom of the last and then passing along the outer sides of the last and finally carried upward to its top.

In the example of this process shown in the drawing, it is supposed that only the front part of the upper is to be lasted in {he manner referred to by means of a wireoop.

Figure 1 is a bottom view of the last with the lasted upper on it.

Fig. 2 is a side view of the same.

Fig. 3 shows, on a larger scale, an exampleof the means used for guiding and fastening the wire-loop, whose ends are fastened at the top of the last.

A wire loop 4 for the lasting operation is secured by stitching to the lower edge 5 of the upper which is to be lasted. The ends a and 6 project from the stitched edge and are free at the shank of the upper. The upper having said wire loop attached is placed on the last and the free ends a and b of said loop are passed in opposite directions over the bottom of the last and up the sides thereof between the last and the upper, the end a which is connected with the loop at the inside edge of the upper being passed up over the outer face thereof, and the end 6 which is connected with the loop at the outer edge of the last being passed up over the inner face thereof; said ends being preferably crossed diagonally over the bottom of the last. These ends are pulled taut utilizing the sides of the last as bearing surfaces, and then Specification of Letters Patent.

ed to fit at its lower end in said socket This rod is provided at its upper end with a vertical screwthreaded socket 20 in its body and with a shoulder 21 having a conically' flaring clamping jaw 8 projecting beyond said socket 20. This jaw is provided with grooves and holes 7 which connect the mouth of the aw with the base of the shoulder at opposite sides of the rod 9 for the passage of the wires. The other member of the clamping holder consists of a rod 13 provided at its lower end with a reduced screwthreaded tang 12 adapted to fit the screwthreaded socket 20 and with a shoulder 30 at the base of said tang. A conical jaw 11 having a central hole is loosely disposed on said tang 12 between the socketed end of the rod 9 and the shoulder 30 of the rod 13. This conical jaw 11 fits within the flaring conical jaw 8 and is moved toward or from said flaring jaw by the turning of the rod 13.

After the free ends a and b of the wires of the loop 4 are passed up the opposite sides of the last as aforesaid and drawn taut, they are threaded through the holes 7 of the jaw 8 and through said jaw. Then the rod 13 is turned and the conical upper jaw 11 is forced into the flaring hollow jaw 8 and said wire ends a and b are clamped firmly between said jaws.

I claim 1. The method of lasting shoes and boots, which consists in sewing a wire to the lower edge of the forepart of the upper, placing the upper with the sewn-on wire on the last, crossing the ends of the wire on'the bottom of the last, passing the ends of the wire along the outer sides of the last, between the sides of the last and the upper up to the top of the last, then lasting the upper leather by pulling the ends of the wire, and fastening these at the top of the last after the lasting is accomplished.

2. In a method of lasting shoes and boots, those steps which consist in sewing a wire to the lower edge of the fore part of the upper, placing the upper with the sewn-on In testimony that I claim the foregoing wire on the last, passing the free ends of as my invention, 1 have signed my name in 1. Enid wire opposite? directions oger the presence of two subscribing witnesses.
