PATENTED FEB. 16, 1858.

'0. MONNIN.

ICE SPUR FOR BOOTS 0R SHOES,

UNITE ATET ICE-SPUR.

Specification of Letters Patent No.

To all whom it may concern:

Be it known that I, CHARLES MONNIN, of Buffalo, in the county of Erie and State of New York, have invented a new and improved ice-spur, to be attached to boots and shoes for the purpose of preventing persons from slipping when walking over icy surfaces; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1, is a side view of a boot or shoe, sole and heel with my improvement. Fig. 2, is a bottom or face view of ditto with my improvement also attached.

Similar letters of reference indicate corresponding parts in the two figures.

This invention consists in attaching to the heel of a boot or shoe a metallic strip or plate, bent in bowform, serrated at one edge and so arranged that it may be turned around into the hollow of the sole adjoining the heel, with the serrated edge downward, so as to serve effectually as an ice spur when required, and when not required as such, rendered capable of being turned around so as to snugly encompass the heel and not be an encumbrance to the boot or shoe. The strip or plate being also so arranged that it may be readily attached to and detached from the heel, so that in summer it may be removed entirely from the boot or shoe, and applied as winter or freezing weather approaches.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

- A, represents the sole of a boot or shoe.

B, is the heel, and O, is a metal plate which is permanently attached to the front or inner edge of the heel B, by screws (a) The ends of this plate project slightly beyond the sides of the heel B, and holes are made in the ends of the plate C, to receive the pins (5) of a curved or bow shaped plate D, said pins being at the ends of plate D, one at each end. The plate D is bent or curved to correspond to the heel B, and encompasses it when turned in the proper direction as shown in black, Figs. 1 and 2,

the plate D working or turning either for- 19,87'6, dated February 16, 1858.

ward or backward on the pins (6) as centers. as shown at (0) and when the plate is turned around so as to fit into the hollow of the sole as shown in red in both figures, the serrated edge (0) projects a short distance below the level of the face of the heel and the ball or rounded portion of the sole and serves as a spur or hold-fast. The plate D, has a projection (6) formed on it at its outer part to serve as a thumb piece for the purpose of turning it and the plate D, is held in either of its two positions and effectually prevented from casually moving by the following means. Each end of the plate C is rounded at its outer side as shown at (f) and at each end of the plate D, a ledge (g) is formed, and these ledges project inward so that the ends of the plate C, will extend beyond them as shown plainly in Fig.

2. The plate D, has a certain degree of elasticity, sufiicient to press its ends beyond the ledges (g) snugly against the ends of the plate C, and the plate D, therefore is secured in either position by its own elasticity as the ends of the plate D, in consequence of the ledges (g) mustnecessarily be sprung outward as it is turned in either direction and the resistance offered by the spring or elasticity of the plate retains it in proper place.

In consequence of the elasticity of the plate D, it may be readily detached from the heel by merely springing or distending the ends of plate D, so that the pins (1)) may pass out from the plate O. Conse quently during summer the device may be detached entirely from the boot or shoe, the plate C, of course remaining attached to the heel.

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

The curved or bow-shaped metallic plate D, attached to the heel B, of the boot or shoe and constructed and arranged substantially as and for the purpose set forth.

One edge of the plate D, is serrated
