ANTISLIPPING DEVICE.

Specification of Letters Patent.

Patented May 22, 1917.

Application filed April 26, 1916 Serial No. 93,688.

To all whom it may concern.-

Be it known that I, DAVID GRInvn, a subject of the King of Great Britain, residing at Needham Heights, in the county of Norfolk and State of Massachusetts, have in- Antislipping Devices, of which the following is a specification. r This invention relates to anti-slipping devices for use upon the heels of boots and shoes, the object in view being to produce an efiicient light Weight foldable and portable device of the character referred to, the same being readily applicable to and removable from a heel'and being capable of being compactly folded and carried in the pocket. A further object in view is to provide a device of the character referred to which may be manufactured at small cost and sold for a correspondingly small amount, the device being adjustable to heels of different sizes.

With the above and other objects in view,

the invention consists in the novel construction, combination and arrangement of parts, as herein described, illustrated and claimed. In the accompanying drawings Figure 1 is a perspective view of the device detached, looking toward the upper side thereof. a

Fig. 2 is a similar View looking toward the lower side thereof.

Fig. 8 is a bottom plan view showing the device in its applied relation to a heel.

Fig. 4 is a vertical longitudinal section throughthe same in its applied position.

Fig. is a detail view of the device when folded so as to be carried in the pocket.

The anti-slipping device or ice creeper comprises, in the preferred embodiment thereor, three arms, two of which are of corresponding formation, designated generally at 1, and the remaining or third arm 2 of which is of different formation for a purpose which. will appear. All of these arms 1 and '2 are connected together at one end by a pivot 3 which is preferably of tubular formation for the sake of lightness and. also in the form of a rivet, the opposite extremities thereof being headed as shown at 4 to hold the arms pivotally connected together.

Each of the arms 1 may he formed out of flat bar stock material, preferably of iron, steel or other metal, the full width of the material being used at the inner end of the arm where it is connected to the pivot 3 and being reduced in width as indicated at 5 to allow for the provision of downwardly extending spurs 6 which obtain a grip on a slippery or ice covered'surface. Each of the arms 1 is also provided about centrally thereof with a downwardly punched triangular spur 7 having the same function as the spurs 6.

At its outer extremity each of the arms 1 has an upwardly turned finger portion 8 terminating in an inwardly deflected barb which is adapted to be forced into the heel of a shoe or boot when adjusted in the relation thereto illustrated in the bottom plan view, Fig. 3. i

' The remaining arm 2 is likewise provided with a downwardly punched spur lOhaving the same function as the spurs 6 above described and at its outer end ,the arm 2 is formed with upwardly extending ears 11 formed with holes 12 to receive the oppositely projecting pintles 13 of a pivotally mounted heel gripping member 14 provided at its free edge'with inwardly extending barbs 15 adapted to sink into the front wall of the heel.

The ears 11 are also provided with holes 16 to receive the oppositely projectingpintles 17 of a two-armed lever 18, whereby said lever is pivotally mounted between the ears 11. adapted to work against the'outer faceof the heel gripping member 14 in order to press said member toward the heel and force the barbs 15 into the same while at the'same time forcing the barbs f the arms 1 into engagement with other portions of the'heel. The longer arm 20 of the lever is deflected so as to bear iiatwise or substantially so against the sole of the shoe or boot adjacent to the heel when'the shorter arm 19 has reached or passed slightly beyond a position at right angles to the heel gripping member 14:.

The device is adjustable to heels of different sizes as clearly indicated by thefull and dotted lines in Fig. 3, it being necessary only to adjust the outer ends of the arms 1 to different points along the outerface of the heel until the heel gripping member 14 is brought into such relation-to the front face of the heel as to insurethe pressing of the heel engaging spurs'into the leather or other material of which the heel is composed. lVhen not required for use, the de- The shorter arm 19 of said lever isvice is detached from the heel by moving the longer arm of the lever 18 dmrnwardly,

" after which the arms may be folded on the common pivot 3 until they occupy the relative positions shown in Fig. 5. The device may then be placed in a small carrying case and placed in the pocket for use whenever the occasion arises.

" I claim In an anti-slipping device of the character set forth, the combination-of three arms stamped from sheet metal and all connected together by andradiatingfrom a common connecting pivot two of said arms being provided with downwardly projecting barbs punched therefrom and bent to form termi- Games of thin metentmay be obtained for five cents each, by addressing the Commissioner of Patents,
