RUDOLPH MALPERT ATTD R N EYB Patented Jan. 25, 1949 UNITED STATES PATENT OFFICE SLEET CUTTER Rudolph Malpert, Fargo, N. Dak. Application May 16, 1947, Serial No. 748,408

2 Claims. .(Cl. 36-62) This invention relates to a Creeper adapted to be worn on overshoes or rubbers to keep the wearer from slipping on the ice.

It is an object of the present invention t-o provide a Creeper wherein .the cutting elements will be self rcles-ming and wherein `the .strap or band to which the Cutting elements are attached can be adjusted inwardly upon the ycutting elements to iit the creeper to different size shoes or rubbers.

Other objects of the present invention are to provide a creeper adapted for use on overshoes which is -of simple construction, inexpensive to manufacture and efficient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a side elevational view of a rubber with an ice creeper embodying the features of the present invention connected thereto.

Fig. 2 is a bottom View of the ice Creeper with portions of the band broken away to show the connection of the/creeper kelements therewith.

Fig. 3 is a ear elevational View of the rear creeperlglew and Fig. 3a is a bottom plan View of the e ent.

4 is a front `elevational view of one yof the ther Creeper elements and Fig. 4a is a bottom plan view of this Creeper element.

Fig. 5 is a transverse cross-sectional View taken on line 5-5 of Fig. 4.

Fig. 6 is a rear elevational view of the entire Creeper assembly.

Fig. 7 is a longitudinal cross-sectional View taken on line l--l of Fig. 6.

Referring now to the figures, I represents a rubber or overshoe to which my creeper'device is fitted. This device comprises a wide band II of U-shape having an intermediate groove portion I2 adapted to receive the `edge I3 of the heel of the rubber II). The forward part of the band or leg portions .thereof have slots I4 through which a strap I is extended and fastened by a buckle IIB over the forward part of the rubber to secure the Creeper upon the heel against rearward displacement.

This band II is made of steel and its leg portions Can be flexed inwardly or outwardly to adjust the same to different size heel edges I3. In the rear -of the band is a fixed and permanently secured cutting element I8 having a cutting edge I9 andcut-a-Way portions 2| and 22 respectively forwardly and rearwardly thereof. This -cuttingelement I 8 extends below the bottom edge of the band Il Vand is engaged upon its top part by the bottom of the rubber heel.

Other cutting elements having a similar cutting edge 23 and cut-a-way

portions

24 and 25 are disposed between the leg portions of the band at longitudinally spaced locations forwardly of the cutting element I8. These cutting elements are indicated at 26 and 2l. Each of these cutting elements have a threaded portion 28 extending from each of their ends and through openings 29 in the band. On each threaded portion are washers 3| and lock nuts 32 for adjustably securing the band on the threaded porti-on so that the legs of :the band can be adjusted to different positions on the cutting elements and so as to adapt the band to different size heels I3. rThe threaded portions 28 lie flush with the vupper edge of the cutting elements so that 'the Cutting edges 23k will be offset downwardly therefrom. The cutting edges `of all -of `the Cutting elements ex-V tend below the bottom edge of the band.

While various changes m-ay be made in the detail construction, it shall be understood that such changes shall be Within the spirit and scope of the present invention asr dened by the appended claims.

I claim:

1. An ice Creeper comprising a band adapted 'te' 'to t about the heel of an overshoe or rubber and/f to extenddownwardly from the bottom thereof;

' cutting elements secured between the legs of the .band and ext-ending downwardly from the bottom edge of the band for engagament with therice, and a strap adapted to extend from the leg por-` tions over the front of vthe `shoe, and said cutting elements having threaded portions on the opposite ends of the same adapted to extend through the leg portions of the band, and lock nuts for fixing 'the band at its adjusted position to the threaded portion of the cutting elements whereby the band .can be .adjusted to different width shoes.

2. In an ice-Creeper, a plurality of removableu* and replaceable ground-engaging elements each comprising a transversely extending body portion having blades formed in the lower face thereof and an outwardly extending threaded attaching lug at either end of said body.
