UNITED STATES PATENT OFFICE Max:113; trues This invention relates to new and useful imarovements in chocks for wheels and other cir-'- :ular or cylindrical bodies;

The principal object of the present invention is toprovide a chock of yieldable construction to the end" that it will conform with the curved surface of circular or cylindrical bodies over a substantially wide range of diameters, to the end that'full checking ability is available for numerous sizes of work without entailing the necessity of keeping on hand a number of different size chocks, especially in so far as retail dealers are concerned. I I

Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawings:

Figure 1 represents a fragmentary side elevatlonal view showing a wheel engaged completely with the chock.. v

Figure 2 is a fragmentary side elevationalview showing a smaller wheel engaged with the same chock and'before the chock has been deformed by the weight of the wheel to full contact.

Figure 3 is a fragmentary side elevational view showing the wheel of Figure 2 driven onto the chock and fully contacting the same.

Figure 4 is an enlarged side elevational view -of the chock.

Figure 5 is a top plan view of the chock.

Referring to the drawings wherein like numerals designate like parts, it can be seen that the chock of spring material so that it will yield and contact for its full extent the work it is to chock. The chock is constructed of one elongated strip of spring elongated strip A has its lead edge tapered, as at I. The other end portion of thestrip is in the form of a leg 6 which also has its lower end tapered, as at 1, so as other supporting surface. The leg 6 serves to elevate the adjacent end of that portion of the strip which will be referred to as a ramp curved to conform with a given are. This arcuateshaped ramp is interrupted at its upper portion by a substantially deepV-shaped offset 8 dcto bite into the road or fit against the ramp from tire will engage the portions I! after having been denoted by numeral A. This ing the wheel onto the As before stated, this chucking lumber. oil drums "claimed as new is:

For instance, this wheel It may be regarded as size 6.25 x i6.

A smaller wheel i barely touch the parts l2 and I3, and would entirely miss the part I of the ramp, but by ridv chock, the chock will deform itself, as shown in Figure 3, so that all portions l2, l3 and wheel.

While the roregoing' specification sets forth the inventionin specific terms,

it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
