IMPROVEMENT IN ICE-CREEPERS.

Specification forming part of Letters Patent No.145,310, dated December 9, 1573; application filed October 4, 1873.

To all whom it may concern Be it known that I, REGINALD H. EARLE, of St. Johns, in the Province of Newfoundland, have invented a new and useful Improvement in Ice-Creeper, of which thefollowin g is a specification:

Figure l is a top view ot' my improved ieecreeper. Fig. 2 is a longitudinal section of the same taken through the line a: x, Fig. 1. Fig. 3 is a cross-section ofthe saine taken through the line y y, Fig. l. Fig. 4 represents a wrench for operating the set-screw.

Similarletters ot' reference indicate corresponding parts.

My invention has for its object to furnish an improved ice-Creeper, neat and simple in construction, and convenient in use, and which will enable the wearer to conveniently and safely walk over the smoothest iee. The indvention consists in the combination ot' the grooved plate, the sliding halved plates pr0- vided with inwardly-projeeting spikes at their turned-up outer ends, the set-screw, and the downwardly-projecting spikes with each other, as hereinafter fully described.

A is 'a narrow plate of such a length as to reach across the sole of the boot. upper side of the plate A, along' its side edges, are formed grooves to receive the side edges of two plates, B, the inner parts ot' which are halved, so as to overlap each other without producing any extra thickness. The movements of the plates B, as they are slipped ont Upon the and in, are limited by pins attached to the upper side of the ends of the plate A, and which project through short longitudinal slots in the plates B. rlhe outer ends of the plates B are bent upward at right angles, and have spikes O attached to them to enter the edges of the boot-soles. D is a set-screw, which passes up through a screw-hole in the middle part ofthe plate A, so that its forward end may press against the plates B and press 4them against the iian ges that forni the grooves in which the edges of the said plates B work. To the under side of the plate A are attached two or more short spikes, E, to take hold of the ice, and thus prevent the wearer from slippin In using the creepers, the set-screw D is loosened, and the plates B are drawn outward. The Creeper is then placed upon the sole of the boot, and the plates B are forced inward, fore ing the spikes O into the edges of the bootsole. The set-screw D is then tightened, and the Creepers are ready for use.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The ice-Creeper, constructed of the grooved plate A, the plates B, sliding on each other, and having spikes O, and the setserew D, arranged as shown and described.
