DISK-WHEEL ASSEMBLY.

Specification of Letters Patent.

Patented May 24, 1921.

To all whom it may concern:

Be it known that I, VICTOR Loucmmn, a citizen of the United States, residin at Santa Barbara, in the county of Santa arbara and State of California, have invented certain new and useful Improvements in Disk-Wheel Assemblies, of which the following is a specification.

This invention relates to metal wheels built up from a hub, a rim, and a web connecting the hub and the rim, and particularly to the construction of the web and the manner of assembling it with the hub whereby the web is better adapted to transmit the load from the hub to the rim and fagntain more secure connection with the The invention consists in constructing the web of a plurality of disks, fixedly related in an annulus remote from the hub but spaced apart and movably related at their centers or place of section with the hub, but there rovided with means for clamping them rmly and solidly against a hub part, a suitable filler being introduced between the disks at the place of clamping, and the disks being given a firm or permanent set which normally holds them slightl away from their spacing fillers when unc amped, but within reach of said fillers under the clampin action without exceeding their elastic hmits; so that when clamped the disks are left under initial strains in the direction of resistance to the load which they are to carry; and bolts, which are re erably used forthe clamping means, Wlll be locked a inst unscrewing by the resiliency of the disks in opposition to the clamping pressure; and, if preferred, one or more of the disks can be brought into radial bearing upon the barrel of the hub and given an initial firm pressure thereon by distortion incident to the clamping action.

The invention Wlll be fully understood upon reference to the accompanying drawing in which igures 1, 2, and 3 represent in axial section three embodiments of the invention.

In eachof the figures A represents the hub having a flange B and a barrel C, and D represents the web which carries the rim E and is clamped to the hub between the clampin plate F and the flange B throu h the medium of bolts G having nuts g. eb D is composed of two disks 0! and d in Figs. 1 and 3, and three disks, d, d, and d in Fig. 2. The disks which compose the Web are fixedly related in an annulus remote from the hub, for instance, at the inner circumference H of the rim E in Figs. 1 and 2, and at the intermediate resilient zone K and also at the rim circumference H in Fig. 3, to which the disks extend in the diver ent annular portions d and cl and w ich widens their rim-receivin base.

The disk d in each of t e figures is preferably brought into radial bearing upon the barrel 0 of the hub as indicated at d. maintain the bearing of the disk upon the hub when the disk is deflected, by the clamping action hereinafter referred to the inner edge of the disk is rolled axially outward. In Fig. 2 the intermediate disk 03 is likewise brought into radial bearing upon the barrel of the hub as suggested at d, the hub barrel at such point being coned to continue the hearing as the, disk is distorted by the clamping operation. In Fig. 3 the disk (1 is provided in an annulus ust beyond the clamping zone with an additional deflection or swell d which lends to this disk a radial resiliency greater than that of the disk d. It will be noted that the disk of increased radial resiliency is the one which is ste ped directly u on the barrel of the hub at It will furt er be noted that in Fig. 3 portions of the disks lying, respectively, within and beyond the resilient zone K have received two distinct dishings, or a reverse dishing in each disk, which condition also increases radial resiliency and coacts beneficially with the condition of distortion of the disks under the clamping operation and loading them with initial strains.

While the drawin indicates no spacing between the filler b ock and the end disk next to the hub flange, it will be understood that axial stress imposed upon the comanion disk will be transmitted at the annuus of fixed relation (the circumference of the rim in Figs. 1 and 2, and the resilient zone K in Fig. 3), and this will transmit a portion of the load to the end disk until they are equalized.

In each of the forms the disks are spaced apart at the center, where they are received by the hub, through the medium of the filler block I (Figs. 1 and 3) or the divided filler block I, I (Fig. 2). In each of the forms the disks are dished and given an original form or permanent set which causes them to space themselves apart a distance slightly greater than that measured by the thickness of their filler blocks, as suggested by the dotted and full lines in the figures, so that when clamped tightly betweenthe plate F and the flange B, by drawing up their clamping bolts G, the disks will be put under initial strains in the direction of the load which they are to bear in use, and they will be better adapted to stand up under loads imposed upon them. These strains, in the disks (Z, d in each form, will be of compression, since a pressing of these disks toward each other tends to flatten out their dishing, and this is resisted b 1 the rim. The intermediate disk 03 in ig. 2, if given a substantially flatv form in its original set, will be slightly dished'in the clamping operation and put under strains of tension. It will thus be seen that the kind of initial strains imposed upon the disks may be determined by the initial form imparted to the disk and the form to which it will be distorted under the clamping operation. 3 It will also be seen that since the disks constantly oppose the clamping operation by their rcsiliencyin seeking to return to their normal shapes, frictional pressure will be maintained at all times against the nuts 9 which will effectively lock them against unscrewing.
