ANTISLIPPING DEVICE.

Specification of Letters Patent.

Patented Apr. 30, 1912.

Application filed August 'l, 1911. Serial No. 642,329.

To all whom it may concern:

Be it known that I, WILLIAM FINDLAY, a. citizen of the United'States of America, and a resident of the city of New York, Long Island City, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Antislipping Device, of which the following is a full, clear, and exact description.

My invention relates to anti-slip ing devices -to be worn upon the sole 0 a shoe and provided with means for their easy removal and replacement, and also for their reversal so that when worn from one side they may be turned over so as to expose the fresh antislippin surface to the ground.

Reference is to he had to the accompanying drawin forming a part of this specification, in w ich like characters of reference indicate corresponding parts in all the views, and in which-- Figure 1 is a perspective view showing a shoe provided with my improved anti-slipping device; Fig. 2 is an inverted plan or bottom view of the anti-slipping device; Fig. 3 is a front view showing the anti-slipping device in cross section, the shoe appearin in elevation; and Fig. 4 is a section through the anti-slipping device and is taken on a plane crossing the general direction of the length of the strap.

A shoe 5 is provided with a sole 6 and is of the usual or any desired construction. I provide a strap 7 having a portion 8 bent backwardly so as to form a loop 9, this loop carrying a buckle 10 throu h which the free end of the strap may be s iipped, the strap being secured in a manner well known in this art. I also provide two plates 11 of sheet material, and in this instance circular in form. The plates 11 are, by the simple operation of punching or stamping, provided with rough teeth 12 which are merely integral portions of the plates 11 turned outwardly.

Two plates 11 are secured together by aid of rivets 13. These rivets are spaced far enough apart to allow the plates a little room in which to bend in order that the strap 7 may be threaded between them. The plates 11 are placed back to back; that is, the teeth of one plate extending in a direction opposite to the teeth of the other plate. The two plates, when thus secured together, are reversible relatively to the strap; that is to say, the pair of plates, as a unit, may

be slip ed ofi' the strap, turned over, and placed back on the strap in order that either of the two roughened surfaces maybe outside of the strap when the strap occupies the position indicated in Fig. 1. After the plates 11 have been secured together by the rivets 13 the same are bent slightly apart for accommodating strap 7.

The operation of my device is as follows: The unitary member, consisting of the two plates, is fitted upon the strap as shown, and the strap is buckled upon the shoe as indicated in Fig. 1. The shoe now being laced upon the foot, whenever the user wal (s, the

lowermost group of teeth is forced down flat upon the ground or upon any other surface on which the user is supported. The presence of the teeth 12 and .their roughness prevents the shoe from slipping.

My device is of peculiar value to enable people to walk upon the ice and snow with out the danger of falling.

I do not limit myself to the mechanism shown, as numerous variations may be made therein without departing from the spirit of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is za 1. As an article of manufacture, an antislip ing device comprising a pair of plates of s eet metal each provided with teeth,said plates being so located relatively to each other that said teeth carried by one plate extend in a direction opposite to that of the teeth carried by the other plate, and a strap extending between said plates for supporting the same upon a wearers foot.

2. A device of the character described, comprising a pair of plates of sheet metal; each plate being provided with teeth formed integrally with it, the teeth of one plate extending in a direction opposite to that of the teeth of the other plate, a. plurality of rivets extending through both plates for holding them together, said rivets being spaced apart, and a strap extending between said' plates for supporting the same upon a wearers foot.

3. As an article of manufacture. a pair of plates of sheet metal, each plate being provided with teeth integral with it, the teeth of one plate extending in a direction opposite to that of the teeth of the other plate, and a plurality of fastening members con necting said plates together, said plates being bent slightly apart so as to permit the passage of a strap between said plates.

4:. A device of the character described, comprising a reversible anti-slippi"ng'mem-; her, and a retaining strap adapted to secure said anti-slipping member in position with either face uppermost.

5. A device of the character described, comprising a pair of duplicate anti-friction plates, a projection formed on each plate, means for securing said plates together so that said projections will extend in opposite directions, and a retaining strap adapted to secure said plates in position Witheither plate uppermost.

hold either side of sald -comprising anti slipping means formed with opposite sides of substantially identical c0n- "SEIUCti'OIr, and a retaining strap extending through said anti-slipping means adapted to anti-slipping means uppermost.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
