METAL WHEEL BLOCK.

Application filed January l thereof.

My invention relates to wheel blocks for supporting pneumatic tired wheels in shipping or when for any reason it is desired to so support the tires that the weight of the l vehicle will be so distributed as not to bear wholly upon the portion of the tire in contact with the floor or ground. My invention has for its object to provide a wheel block for this purpose which may be formed of a single strip of metal by bending, will be rigid and not to be distorted in use and will have at all points which can come in contact with the tire rounded surfaces.

With these and other objects hereinafter $5 explained in view my invention consists in the construction and combination of elements hereinafter described and claimed.

Referring to the drawings: Figure l is a plan view of the sheet metal blank from which my wheel block is formed. Figure 2 is a view of the block from the front or higher end, partly broken away.

Figure 3 is a view of the block from the rear or lcwer end. Figure 4 is a side view; and

Figure 5 is a perspective view of the block.

Figure 6 is a side view showing the blocks in place with the wheel of the car resting thereon.

The blank from which the wheel block is formed comprises end or leg portions 1 and 2 and mid portion or tire supporting ortion 3 forming together a strip of s eet metal. The end portions 1 and 2 are provided with

longitudinal corrugations

4, 4. At their ends the end or leg ortions 1 and 2 are each cut away at an ang e of about 45 degrees and strips 5 and 6 at the ends of the end or leg portions are turned outward at about ri ht angles to the body parts of these emf portions to form supporting feet. Along the edges of the body part of the end or leg portions 1 and 2

narrow strips

7 and 8 are turned inward.

angles as shown at 9 and the strips 8 along ends of the mid portion 3 as to leave sub- 8, 1925. Serial No. 1,181.

These inturned

strips

7 and 8 are cut away on the lines on which the end strips are bent, the strips 7 along the longer edges of the portions 1 and 2 being out at right 50 the shorter edges. being cut on the line of the fold as shown at 10-. The end strips are cut away on their ends near the strips 7 as shown at 1112 and on their ends near the strips 8 are cut away as shown at 13. At

their ends adjacent the mid portion 3 the

strips

7 and 8 are cut away at angles of about 45 degrees as shown at 14 and 15, the cuts being made at such distances from the 7 0 stantial

intermediate portions

19 and 20 between the inner ends of the cuts and the adjacent end of the mid portion.

Strips

16 and 17 along the edges of the mid portion 3 are turned inward at right angles. These

strips

16 and 17 are cut away at their ends at right angles to the edges'of the mid portion. v The blank being thus cut to shape and the

ends

5 and 6 turned outward (or up) and'the

edge strips

7, 8 of the end portions and the

edge strips

16 and 17 being turned inrward (ordownward) the blank is ready to be bent to form.

The mid portion 3 is curved to the concave form shown in Figures 2, 3 and 5, the

edge strips

16 and 17 following the concavity and serving to hold the mid portion rigidly in shape. The

strips

7 and 8 being bent at right angles to the bodies of the end portions 1 and 2 serve with the corrnggtions 4 to maintain these end portions r1g1 On the lines joining the mid portion 3 and the intermediate portions 19' and 20 the metal is bent outward to a sharp angle'as shown at 21 and from these lines the metal of the intermediate portions is bent inward so as to bring the

angular ends

14 and 15. of the

ed e strips

7 and 8 against the under 1 face of t e mid portion 3. The inwardly

bent strips

7 and 8 thus serve to support the mid portion 3 and to prevent any tendency to break atthe sharp bend 21. The'reverse bend of the intermediate portions 19 1 and 20 brings the inner ends of the

end portions

7 and 8 directly beneath the edges of the mid portion 3.

In the completed wheel block the side portions 1 and 2 flare outward at their lower ends, and the

ends

5 and 6 are bent outwardly at such angles that they will rest evenly on the floor.

'

strips

16 and 17 of the mid portion 3 are also so bent as to present rounded surfaces unbroken.

along their upper faces. The upper concave surface of the mid portion 3 is smooth and Having thus described my invention what I claim is:

1. A' block for pneumatic tired wheels formed of a singlestrip of sheet metal coml'e portions flarin outward. at their ower .en s provided wit ends outwardly away ,of t e concave mid portion.

whereof I hereunto aflix my 40 bent to form supporting feet and a mid portion coneaved to receive the tire having end strips bent downward, the portion between the upper ends of the leg portion and the mid portion being turned outward and lower ends provided with ends outwardly .bent to form supporting feet and a mid portion concaved to receive'the'tire having end strips bent downward, the portion between the upper-ends ofthe leg portion and the mid portion being turned outward andfolded inward upon itself so as to bring the upper edges oftheleg portions beneath it,

the leg portions being provided with in-,

wardly bent strips along their ed es cut at the upper ends to fit the un er face I In testimony signature. 1 LESTER E. CAMPBELL.
