To all whom it may concern:

Be it known that 1, WILLIAM Emsros Winners a citizen of the United States,

and a resident of Chicago county of Cook,

and State of lllinois, have invented a new and useful improvement in Pressed Steel Wheels, of which the following is a specification.

My invention relates to steel disk wheels having special shaped corrugations and the objects of the invention are to provide a strong elastic'disk and of a shape that will facilitate its fabrication into a wheel having general merits as described herein,

Reference will be had to the accompanying drawing in which F igure 1 is a front elevation of the wheel.

Fig. 2 is a diametrical section.

Fig. 3 is a perspective View of a section of a serrated ring used in securing the brake drum to the wheel.

Fig. i is a plan detail showing how the disk is made.

In the drawing 1 indicates the axle of a wheel and 2 the ordinary hub as found on an automobile but in this case adapted to suit my wheel, 3 indicates the common brake band drum fitted to my wheel, i indicates the regular demountable rim as commonly used and secured in place by wedge clips 5.

My corrugated disk is indicated by 6 and it is formed from a straight strip of steel approximately of a width equaling the length of. the circumference of the wheel and it is formed into a disk shape by tapering corrugations as indicated in Fig. i. The corrugations start from a smooth surface a short distance from the outside thus leaving a flat flange 7 on the rim which is turned over laterally to form a sort of rim 8 for the disk.

The corrugations are deep enough the hub side 9 to take up the edge 10 oi the straight strip 11 and bring it around into a circle forming a complete disk The ends the sheet after forming the disk are welded or otherwise suitably joined acomplete circular disk is formed having as much met on the hub circle the rim edge ins arriving at stantial and eificient construction using the metal without waste and getting of all of it.

in forming n these faces rest the inner plane face of the brake drum. The annular main body oft-h disk is dished, its peripheral portion being carried toward the front or the wheel, and through the peculiar dishing there is produced the angle 15 and the bulge 16 in the corrugations. This dishing has the eflect of giving the disk a spring or elastic form in the matter of the thrust strains between the hub and the rim thus producing an elastic wheel. Further by bringing the rim of the disk forward or toward the front it facilitates the fastening or: the disk to the flange 13 of rim 14: as the rim 14 then can be made of a simple strip in the same manner as common rims.

The disk is pressed into the rim l4 and there is provided a clamping ring 17 which clamps the disk to the flange 13 of rim 14 by means of the rivets 18 or spot welds as desired.

The hub hole of the corrugated disk 6 is hushed by a casting 19 which is cast on the inner .en s of the corrugations. Since the disk is made of thin metal this cast on bushing usually welds fast to the disk sheet and in any case binds very tightly to the sheet and makes the disk very stiff at the hub. l he casting 19 is machined to fit the hub 2 and is secured thereon by a screw threaded collar 20.

The brake drum 3 is offset at 21 to fit over the inner end or cast bushing 19. The rim of the drum is secured to the disk 6 by the notched ring 22 riveted or spot welded at 23 to the drum 3. The notches 24 it over the sides of the corrugations of the disk and flange ends 25 are secured by rivets or spot welds to the front faces of the corrugations of the disk 6.

The metal of the dish 6 is quite thin and this notched ring 22 secures the brake drum 3 to the entire disk and the same time it dams off the void spaces oi inside cor rugations along the face of the brake band drum.

What I claim is:-

l. in a wheel oi the class described, a

dish having tapering corrugations extendradially deeper at hub and shallower rim the back faces of the corrugations on the inside o the wheel adjacent the hub being in a -ne an 1 he pe ipheral zone being dished outwardl more that plane.

48 described, a disk 1,. in a wheel oi the disk being dished outward at the point of connection to the rim of the wheel,

3. in a wheel of the class described, a continuous metal disk having tapering corrugations extending radially outward from the hub region to an annular non-corrugated zone which is dished outward, with respect to a transverse plane 'passing perpendicularly through the free end of the axle, to a plane beyond the plane of the other parts of the disk, the outer part of said dished portion forming an annular rinrreceiving flange approximately perpendicular to the general plane of the wheel.

4. The combination with a wheel disk having tapered corrugations extending radially from the hub region to an annular non-corrugated zone which is dished outwardly, its outer portion forming an approximately cylindrical rim-receiving flange or a hub-em circling sleeve rigidly fixed to the corrugated central margin of the disk.

aeeasso 6. A wheel. composed of a disk havin radially extending corrugations and dishe across the'corrugations thereby producing a radial spring construction.

7. In a wheel of the class described, the combination of a hub, a radially corrugated disk, abrake drum fitting over the hub and against the disk corrugations and a sleeve ring having one end portion fitting over and rigidly fixed to the drum and. the opposite end portion notched to fit the contour of the corrugation and rigidly fixed to the reentrantportions of the latter.

8. In a disk wheel having a radially corrugated disk, a straight inside back face for the corrugations adjacent to the brake drum and the corrugations dished or bent outward from a line radially beyond the margin of the brake drum to the position of the flange on the front face of the rim.

9. A wheel of the class described having a corrugated disk corrugated radially and with a bend or dish made transversely of the corrugations between their ends, thus changing the direction of the radial thrusts, with a rim on the periphery of the disk and a hub at the center.

Signed at Chicago, in the county of Cook and State of Illinois, this third day of September, 1919.
