T 0 all whom it 1mg concern."

Be it known that I, HERBERT Ansrrn, a subject of the King of Great Britain, and residing at Bromsgrove, in the county of Worcester, England, engineer, have invented certain new and useful Improvements in- 1toad-Wheels of the Sheet-Metal Particularly in Such "Wheels l Vhich are Used "with Automobiles, of which the following is a specification.

- his invention relates to sheet metal disk Wheels having radial flutes or corrugations, which may represent spokes, and which are clamped at their inner ends within correspondingly formed recesses in a flange or shoulder of the Wheel hub, and consists in forming the corrugations at their inner ends with straight slanted sides and so disposing the corrugations that they, and the spaces between them, are symmetrical about a median plane which is at right angles to the wheel axis. advantage that a disk may he put on either way around, and ii", as is preferred, the recesses in the hub are of the same shape and as the spaces between the corrugations of the disk, the said corrugations, when tightened up in relation to the hulnengage the of such part with wedging action. The recesses in the hub do not necessarily correspond in. shave or size to the spaces between the corrug tions o. the disk, but may he of any dimension so lo us they are such as to fulfil the above Furthermore the construction permits similar disks being clamped together th the corrugations of the one engaging with. and Wedging, into, that of the other. symmetrical construction of the corrugations allows a space to he left between the base of a. recess or space and the end surface of a, corrugation thus leaving draft for tightening or wear. The disk is preferably formed with a central hole to allow it to he passed over the hub, and the corrugations aforesaid immediately surround this hole. To fix the disk to the hub, its corrugations are placed within and tightened up into the corrugations of the hub, such as by bolts which pass through. the disk and through pass through the disk and enter the shoulder, or. by a nut or screwed collar which is screwed upon the hub; The disk may be dished, if desired, in

Type, More Such a construction has the motion.

which case the rim may be in a different plane from that of the middle of the disk.

In applying the invention to a twin tired wheel, two disks constructed as above described are used, each carrying a rim, and they may each tions engaged with corrugations formed in a separate flange oi the wheel hub; or the corrugations of the one may be fitted within the corrugations of the other while the corrugations of one of them are fitted within corrugations oi the hub. In such case each of the disks is preferably dished in a direction away from the other. of the liars may, ii desired, be fitted intd corrugations at opposite sides of a flange on the hub. In either case the disks are clamped together and to the flange or shoulder, as the case may he, as above described.

In order that the invention may he readily understood, 1' will now describe convenient applications thereof, by reference to the drawings herewith, of which Figure l is a vertical section of a portion of a wheel constructed according to this invention, the section being taken in the plane indicated by the line 1, 1 of Fig. g

Fig. is a fragmentary outer side view of the hub of the wheel illustrated in Figs. 1 and 2, or the hub of the Wheel illustrated in Figs. 3 and 1.

F 3 is a spread out sectional View of the section being taken. on line 6, 6, of F ig. 4:.

Fig. 7 is a fragmentary sectional view to illustrate a modification of the means for securing a disk upon the hub.

Fig. 8 is an outer side View of the Wheel portion shown. by Fi '7 and i. Fig. 9 is a view corresponding to F ig. 6, except that only one disk is shown, and illustrating a modification in which a washer is placed between the dish and the nuts of the securing bolts.

Referring first to F l, 2 and 5, A is the disk carrying at its outer periphery a grooved rim adapted to receive a tire and Ofillllll have their corruga The corrugations I inner and outer surfaces of the disk a flange Ii formed with ing holes in the flange the disk be seen in these views having spokes. I, pressed out from. its surface. The spokes t; together with the spaces between form at their inner ends a circular series of similar corrugations constituting beveled angular .rihs'and flaring angular recess s having parallel plain portions atthe shown ll the wheel huh having a corrugatitms constituting: beveled angular ribs and flaring; angular reces .5 having parallel plain portions at the inner and outer faces of the llnnge to vorrespond with those of the disk. The dis-1i; A has a central hole and put on over the-nutriend. of the hub and its corrugations a are clamped within those of the flange (Z by bolts 6 which are passed through holes in the inner ends of the spokes and through (Ul (spend- I (I. As he seen from the drawings the corrugations are so arranged that those of the disk will wedge in Fig. e.

themselves within those of the flange, spaces f being left to allow of this.

Referring now to Figs. 3, 4, 5 andv 6, two disks 1 and C are provided each dished in a direction away from the other. The. disk A has spokes I) and corrugations 1: while C has spokes f/ and corrugations 71.. The corrugations (1' are fitted withintho corrugations h and the latter are fitted within corresponding corrugations formed in the flange d," of the huh B. The disks and flange are then bolted together as described. with reference to the single disk. and flange described with reference to Fig. l. It will i that a corrugation of either dilt which forms the inner end or a spoke of such disk corresponds with corrugation which forms one of the spaces be? tween two spokes of the other disk.

Referring to Figs. 7 and 8, A represents a single disk secured in place by a nut e which. screwed on to the hub from the outer face thereof. g between the not a and the disk and having a plainouter surface and corrugations in its inner surface to correspond with the eorru gations of the disk.

Referring-to Fig. 9, the flange (i is shown with corrugations only on the side which is toward the disk its other side being formed plain. In this view a single disk shown, and in lieu of the nuts of the bolts hearing directly on the disk, a Washer 7 is interposed between such nuts and the disk. The Washer is shown as having corrugations only on that-side which is toward the disk. the other side being formed plain.

The washer described with reference to Fl 5.7 and and, also that describe-1i with re erenee to Fig. 9 may, for the sake of lightness, he formedv with corrugations in their outer side faces also, if desired; or such washers may have hoth their faces formed plain.
