ANTHONY T. WILLIAMS, OF TRENTON, NEW JERSEY.

lCE-CREEPER.

SPECIFICATION forming part of Letters Patent No. 375,110, dated December 20, 1887.

(No model.)

To all whom it may concern:

Be it known that I, ANTHONY T. WILLIAMS, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Ice-Greepers5 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to ice-creepers of the sort having spurs on hinged or pivoted plates which are arranged to be turned under the heel for use or turned out of the way when not used. Hitherto such plates have usually been attached to leather shoes and turned forward under the hollow of the foot.

The object of my invention is to improve this class of devices and adapt them to be used with india-rubber shoes or boots. To this end I avail myself of the elasticity of the india-rubbers, setting therein two staplesone for holding the plate in position under the heel and another for holding it when turned out of use. The plate is provided with two opposite curved flanges at its end. One or the other of these flanges snaps over one or the other of said staples according to the position of the plate.

In the accompanying drawings, Figure 1 represents a side view of a rubber-shoe heelhaving the plate turned up vertically behind it and caught in the position it occupies when not in use. with the plate in operative position. Fig. 3 represents a perspective view of the heel and these attachments, taken from below and obliquely in front, the plate being shown as approaching the staple, but not yet engaging therewith. Fig. 4 represents a vertical crosssection through the heel just in front of the lower staple and looking backward, the plate being out of sight.

A designates the shoe-heel, having a staple, a, driven through the back thereof and another staple, a, driven up through the bottom thereof. These staples are provided with sharp points, as shown, which are clinched within the-shoe in the usual manner. The lower staple, a, must be practically embedded Fig. 2 represents a similar view in the rubber of the heel, so that it may cause no inconvenience in walking when the plate is not needed.

At the junction of the back and bottom of the heel a ring or staple, b, is set into the rub her. To this one end of the plate B is hinged by means of a bent lip, b, which practically forms a broad eye. Said plate is provided with spurs 0, extending downward when said plate is in the-position shown in Fig. 2, their function being to catch in the ice and sleet,so as to prevent the shoe from slipping thereon. The end of said plate away from lip 72 is provided with two broad flanges, d d, curved away from each other, the flange 02 being intended for engagement with the staple a when the plate is in the position shown in Fig. 1, and the flange (1 being intended for engagement with the staple a when the plate is in the position shown in Fig. 2.

The length of plate B and the distance from ring b to staple a are so related to each other that the back of the curved flange d is in contact with the crown of the staple a when turned under the heel. A pressure on this plate will cause said flange to slip beyond said staple, the rubber of the shoe yielding to allow this, and the elasticity of the rubber will then cause said flange to snap into engagement with said staple. No elasticity is necessary in the plate itself, although it may be elastic. The distance from ringb to staple a is similarly related to the length of said plate, and the operation when the plate is turned up, as shown in Fig. 1, is precisely that above described. Of course the position of staples a a and consequent length of the plate B may be varied, said plate extending entirely across the bottom of the heel, if pre ferred. The plate B may also be detachable, instead of turning up behind the heel, as stated, it being "used with the staples a and b, as hereinbefore described. It may be made of metal, leather, rubber, or any other suitable material. Any piece which will serve as a catch for flanges dd may be substituted for staples a a.

Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is

1. A rubber boot or shoe having a spurred or roughened ice -creeper plate attached thereto at one point and a catch engaging the said plate at another point by the elasticity of the rubber, substantially as set forth.

2. A spurred plate, in combination with a rubber heel to which it is pivoted, and two staples, one in the back of said heel and one in the bottom thereof, said plate engaging one or the other of said staples, according to position, and being held in such engagement by the elasticity of the rubber, substantially as set forth.

3. The plate 13, having reversely-curved flanges d d at one end, in combination with :5 staples a or, arranged, respectively, in the back and bottom of the heel, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
