AN'rIsLIrPING MEANS. i

Application filed November 17., `1924. Serial No. 750,350.

,'.7'0 all 'whom 'it may concern Be it knownthat I, FRED GUs'rAF BROMAN,

a citizen of the Republic of Finland, and a r resident of the city of Philadelphia, State- 5 of Pennsylvania, liave''invented a new and useful antislipping means to be used in connection with all kinds'of coastingsleds to obtain a firm grip withv the foot'on ice or snow to push the vehicle in a fornf'ard direction or to stop same quickly, also to be used on both feet for the purpose 'of obtaining a firm grip on ice or snow-covered roads, on

slippery surfaces, or for mountain climbing.

Following is a full and exact specification, reference being had to the accompanyingl drawings, wherein:

Fig. 1 is aperspective view of a snowgripper accordingto my invention; Fig. 2

is a calk, specially sharpened, of which two or more are screwed in the bottom of the snow-gripper; Fig. 8 shows the snow-gripper fastened to a shoe.

The snow-gripper is made of malleable iron, cast steel or any other strong material ,25 and is flanged at both sides in such a way that the sole of the shoe, toy which it is attached is pressed between the flanges 1 (Fig. 1) and the broad ends 2 of the two or more callis, which are screwed inthe bottom of the snow-gripper (Fig. A1). r-lhese calli's are forged of high grade steel or made of-any'.

other strong material and vare sharpened in chisel form'in such a way as to obtain the best grip on ice, snow or any other slippery surface. The chisel-sharpened calks are furthermore formed in such a way that they can be easily screwedin the bottom of the snowgripper by means of a wrench or a special key made for that purpose.

In Fig. 1, 1 are the two flanges which' reston the top of the sole edges and 3 the two or more calks, which by fastening, press the sole tight to the flanges 1 as shown in Fig. 3. In Fig. 2 one of the calksis shown in two views. 2 is the part of the calk into Awhich 45 threads are cut to be screwed in the bottom of the body lof the snow-gripper (Fig. 1),

' and 5 is theedge in chisel form, by-which the firm grip on the surface of the ground is obtained. At 6 'the call( isv so formed as 50 i flange at eachend thereof produced by turning the'y ends inward, and calls having threaded connection with the' body `and 65 adapted to be moved into engagement withv the sole of ashoe on which the device is place-dnfor clamping said device on the shoe sole. e Y

3. An anti-slipping means comprising a 70 body adapted 'to underlie the sole of ka shoe.

inwardly turned flanges at the ends thereof' lfor engagement with the'edge of the sole,

and calks provided-with chisel shaped outer ends and screw threaded inner ends, said inner endsadaptedto pass through the body and being of sufcient length to project beyond the inner face thereof for engagement with -the shoe sole to draw the flanges into firm engagement with the edge of said sole.
