IMPROVED ICIEi-SPUIR.A

w The Schedule referred to in these Letters Patent and making part of the same.

Be it known that I, C. l". XVIELAND, of Darmstadt, in the county of St. Clair, and State ot Illinois, have invented anew and improved Spur for Ice and other purposes; and I do hereby declare that the thllowing is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming` part ot' this specification.

Figure 1 is a perspective View of my invention.

Figure 2 is Similar letters ot' reference indicate corresponding parts.

The object ot' this invention is to provide a simple,

.convenient, and etective spur or creeper, so called, for walking on ice or inclined roofs' ot' houses.

It Consists, in general terms, of two U-shaped metal plates, one constituting the heel-plate, andthe other, which is pivoted to it in such amanner as to fold back on the heel, or forward, under the sole ofthe Shoe, bea-rs pointed studs, which enter the surface walked on, and thereby prevent the wearer 'from slipping. p

A coiled spring is arrangedon one ofthe hingepintles Vof the movable part, and is enclosed within a case attixed to the heel-plate.

This spiing keeps the movable part upon the heel, lwhen not wanted-for use, and a spring-catch device retains the movable part under the sole of the foot when in use as a creeper.

In the chawings, A is the heel-plate, and B asimilar U-shaped plate, pivoted thereto by pintle-rivets :l d', one of Y which, d, is merely -a headed rivet, on the heel-plate, while theother, d', is ay pintle, aixed to the plate or part B, and passes through the case .0, turning eely in bearings -aorded by the said case and the plate A.

` a detail top view, showing the catch spring and pin.

A spiral spring isattaehed to -the pintle ll', and a txed stud, e, as shown by the dotted line. This spring, when free toaet, holds the plate B back upon the heel, as .shown in red.

YVhen set for use, the plate B4 is opened forward against the tension ol the spring to the position shown.

a a rr are its pointed studs, for taking hold ot' the ice or root'.

1) are buttons for an attaching-strap, which passes over' the instep and holds the heel-plate'to the heel.

E is a sln-ing-plate, haring a holein which a pin, b, in the plate B eatehes when the said pla-te is extended forward under the sole.

j' is a stud, projecting outi'ronl the spring E,and by striking this stud against any 'tixed object, the spring will be pressed back Iiom the pin 7), thus liberating the plate B,.which will fly bac-k upon the-heel-plate, in obedience to thc spring within the case C.

The spring E is attixed to the heel-plate, as shown, and the i'ree end eneloses-the pintle tZ loosely.

Having thus` described my invention,

I- clain'ras new, and Patent.-

The combination, in aspur or creeper, of thev two U-shaped plates, 'A andiB, pivoted together by pintles d di, and actuated by a spring within a case, C, with the spring-catch E, and pinjb, all arranged and operating substantially as shown and described, and for the purpose set forth.

The above speciiication of my linvention signed b v me, this 31st day ot'August, 1868.
