anrrsnrrrnve DEVICE.

Application filed April 5, 1915.

To all whom it may concern: w

Be it known that I, HAROLD E. CLARKE, a citizen of the United States, residing at Damariscotta Mills, in the county of Lincoln, State of Maine, have invented certain new and useful Improvements in Antislipping Devices; 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 an anti-slipping device.

An object of the invention resides in the provision of a device which is particularly adapted for use on base ball shoes and which may be used as ice creepers and in various other ways.

A further object of the invention resides in the provision of a device which may be readily attached to and detached from the shoe.

A still further. object of the invention resides in so constructing the device that the bending movement of the foot of the wearer will not in any way be interfered with.

With these and other objects in view, such as will appear as the description progresses, my invention comprises the combination and arrangement of parts as set forth in and falling within the scope of the appended claims.

Referringto the drawing: Figure 1 is a bottom plan view of a device constructed in accordance with my invention, showing the same applied to the sole of a shoe. Fig. 2 is a side elevation thereof. 3 is a top plan view, the sole of the shoe being shown in dotted lines and the hooks which engage the edge of the shoe being shown in section.

'Fig. 4 is a rear elevation.

Referring to the drawing wherein like parts are indicated by like characters throughout the several views: In the embodiment of my invention shown in the drawings 1 have provided a plate 1 which is adapted tobe secured to the sole of a shoe by means of clamping members 2 which engage the opposite edges of the sole. The forward end of this plate is provided with a downwardly extending calk 3 while the rear portion of the plate is provided with downwardly extending calks 4. These calks 3 and i are formed integrally with the plate and are arranged in triangular relationship, the two rear calks being in diverging planes Specification of Letters Patent.

and the front calk in a plane intersecting the planes of the rear calks. This plate is formed, preferably, of sheet metal, such as steel, and is considerably lightened by the cutting out of a portion 5.

A substantially V-shaped cut-out portion 6 is provided at the rear of the plate 1 and formed integrally with the plate. At one edge of the cutout portion 6 is a tubular bearing member 7 in which a resilient clamp is pivotally mounted. This clamp comprises a long arm 8 and a short arm 9, the short arm being the arm which passes through the bearing member 7. Onthe end of each of these arms a hook 10 is formed which has a biting edge 11, as illustrated in Fig. 3 of the drawing. When the device is in place upon the sole of a shoe the hooks 10 will cooperate with the clamping members 2 to maintain it in such position and the biting edges 11 of the books will prevent their slipping. The hook 10 on the short arm 9 is arrangedto engage the inner edge of the sole at a point where the ball of the sole merges with the shank thereof, while the hook on the long arm 8 is arranged to engage the outer edge of the sole where the ball merges with the shank. The distance between the books 10 on the arms 8 and 9 is less than the distance between the points on the sole which they engage so that when applying the device it is necessary to force the arms apart and upon their release they will resiliently clamp the edges of the sole and their accidental displacement therefrom will be prevented. The point of connection between the plate 1 and the resilient clamp is such that when the device is in place upon the sole of a shoe it will be located immediately beneath the ball of the foot so that when the foot is bent there will be relative movement between the plate and the clamp and thus the bending of the foot will not be impeded.

It is of course to be understood that it will be necessary, in actual practice, to make this device in various sizes and to make them so as to fit either the right or left foot. It is also obvious that the forms of the calks may be varied to suit the particular use to which the device is put.

The increasing diameter of the sole from the toe portion toward the shank and the engagement of this portion of the sole by the clamps 2 will prevent the plate from moving rearwardly of the sole and the Over hanging portions of the clamps Will prevent the plate from being displaced from the sole. The increasing diameter of the shank of the shoe from the rear to the front thereof and the engagement of the hooks 10 there- With Will prevent the forward movement of the plate 1. Consequently the plate will be positively maintained upon the sole of the shoe.

By making the plate of sheet ,metal and the clamping member of resilient Wire the device can be manufactured very cheaply and can be very readily attached to the shoe.

From the foregoing description it will be seen that I have provided an anti-slipping device Which consists of a plate having a plurality of calks thereon and a resilient clampfor securing the plate to the sole. of a shoe and I have so constructed the device that it may be readily attached to and detached from the shoe. This is particularly advantageous inasmuch as When the device is in use in connection With a base ball shoe, for instance, it may be attached thereto when the wearer is upon the field and detachedtherefrom When he desires to leave the field and Walk upon firmer ground Which Would not be readily penetrated by the calks.

\Vhile I have illustrated and described a particular embodiment of my invention, I r

have merely done so for the sake of convenience and I do not Wish to be limited to that particular embodiment as it is obvious that numerous changes may be made Within the details of construction thereof Without in any Way departing from the spirit of theinvention or exceedingthe scope of the appended claims.

What I claim is I 1. In an anti-slipping device, the combinationvvith a plate, of a resilient clamping member consisting of a pair of diverging arms having hooks on the ends thereof, hinged thereto.

2. In an anti-slipping device, thecombination With a plate having a plurality of calks thereon and a ,V-shaped cut-out portion at the rear end thereof, of a tubular bearing member formed on the said plate at one side of the said cut-out portion, and a clamping member consisting of a pair of diverging arms, one being longer than the other, loosely mounted in said bearing member.

In. testimony whereof, I afliX my signature, in the presence of two Witnesses.
