ICE SANDAL Filed July 22, 1951 3 mvEN-row J0 BY @25a eA/mw ga ATTORNEY Patented July ze, 1932 1f-TENTinnilicazfA WILLIAM H. CRAP, OF PHIIiLIPSJ'RG, NEW JESEY i Ion sANnnr.

Application led July 22,

My present 'invention has reference to a sandal which-is primarily designed for use in the winter time, to prevent persons-using the same from slipping on icy surfaces, al-

5 though the improvement may be successfully employed by athletes or others whose tasks render them susceptible to slipping in the performing of their tasks or work.

A further object is the provision of a sandal which can be easily and conveniently arranged upon the shoe 'of the user, and effectively sustained from movement in any direction when so arranged.

A still further object is the provision of a sandal whose foot or bodyoportion is con structed from a single piece of light but tough material and which is reinforced to eectively strengthen the same in a manner that will not impair but rather insure iiexibility and which likewise will hold the sandal in proper shape and which also provides means for the reception of the shanks of removable calks, that insures the safe 'travel of the user over extremely slippery surfaces.

To the attainment of the foregoing the invention consists in the improvement herein# after described and denitely claimed.

In the drawing:

Figure 1 is a top plan view of the improvement.

' Figure2 is aside elevation thereof.

Figure l3 is asectional view approximately on the line 3-3 of Figure 1.

Figure 4 is a plan view of one of the calks and the attaching element therefor.

As disclosedfby the drawing the sandal 1 is of a shape to correspond with the sole of the shoe upon which the same is to be ar ranged. The sandalmay be constructed of any desired material which is flexible, such for instance, as thick rubber, heavy cardboard having fabric reinforcements, of fabric of a desired strength and thickness, or-.jof sole leather.

At the sides of its toe and heel portions the body of the sandal is formed with lateral extensions that afford straps 2-2, respectively, one of each of said straps carrying a buckle 3 Whose tongue is passed through openings in the cooperating strap, and these straps,

41931.. serial Nas-sasso.:

\ ofcourse, provide 'means wherebyY the sandal is strapped upon the shoe of the user. -0n its upper face the sandal 1, at its point from thetoe, has secured thereto a lsubstantially H- shaped `metal plate. The central element of 65 this plate is indicated for distinction by the numeral 4 and the lateral ends by the numerals5 and 6, respectively.A The lateral extension 6 which is arranged below the sole nearest the instep portion of the sandal is wider than the end 5 of the strip nearest the toe portion of the sandal. The H-shaped stril vi's fixed on the sandal in any desired or pre erred lmanner'and all of the parts provided thereby are formedwith openings that`J` aline with similar openings in thesandal.l The openings in the lateraLetnsions 5 are arrangedclose to the` end thereof "and the opening in the central portion-3l is arranged approximately through the.center thereof. These openings have passed therethrough the* shifinksjl of double headed rivets 7. The

.outer heads-of the rivets afford anti-slipping elements. The rivets from their/outer heads are provided with sockets 8 in which are re- 'I5 ceived the headed shanks 9 of calks 10 which are V shaped, in side elevation and starshaped in plan. The sockets 8 may be slitted to insure the `passage of and the proper frie- -tional engagement with the Shanks when arranged therein."

-At .the rear of the H-shaped reinforcing plate there is secured on the upper face of the sandal the angle -end 11 of another metal re-J inforcing plate. This plate has a downwardly extending portion 12, and from@y thence is formedwith a straight extension 13 which has its end formed with lateral extensions 14. All of the parts of this reinforcing plate are to be secured to the sandal by double headed rivets 15,"and the said reinforcing plates provide the sandal with instep and heel engaging portions when arranged on a shoe. The

double headed rivets 15 that engage the laterally extending end 14 of the rear reinforc- 9 ing plate have sockets which enter from their outer ends and these sockets are designed to removably receive therein the headed shanks of two vof the calks 10. The rivets have been described as double headed, but this is not 10 m Ltllddfftt@ an absolute necessity as the rivets may he of the ordinary t i y and have their shanlrs from their outer ens provided with sockets ao that the upper faces of the callas vvill Contact t with the outer face of the sandal vvhen their headed Shanks are received in the sockets. 'lhis arrangement may', in fact, he found preferable.

rl`he ealks, of course, are of extremely hard it metal and by the employment of suitahle implement, such as pinchers the same may be secured to the sandal or removed therefrom. lt is thought the foregoing description Will fully and clearly set forth the construction Mi and advantages of my improved device so that further detailed description Will not be reuired. q Having described the invention, ll claim: A sandal comprising a body of yieldable material having integrally formed front and rear attaching straps, reinforcing metal plates at the front and at the rear of the sandal, the rear plate having a central portion Which is bent upwardly and from thence arranged at an angle to form the under face of the sandal with a shoulder and With an angle portion, the shoulder designed to be arranged against the heel of the shoe of the user and the angle portion designed to contact With v the shoe adjacent said heel portion, rivets securing the reinforcing plates to the sandal, said rivets being double headed and having sockets entering from their outer heads, and said sockets designed to receive therein and to be frictionally engaged by Shanks on the heads of calks.

ln testimony whereof l aia my signature.
