D IsK WHEEL.

Application The object of my invention is to' provide a demountable disk wheel that will have the least rim weight nd the most secure fastening which l have found it possible to obtain. the accompanying drawing in which Figure 1 is a front eleva tion of the wheel. Figure 2 is a side sectional elevation. Figure 3 is a section through a portion o i the demountable rim. l

Figure 4 is a section through a portion `of the rim showing a modilied form.

Figure 5 is a section on the hub bolt circle. In the drawing 1 indicates a rear wheel l5 h'ub of an automobile, 2 ajflange integral with the hub, 3 the ordinary brake drum, and 4 Vthe tread seat of al demoun tire rim of the quick detachable type, wherein the main rim member 4 is a continuous 2Q integral ring and 5 the snap'ring at one side of the member 4 and having a projection 6 seated in the usual. gutter formed b y the upturn'ed flange 7 of the drop portion '8 of the rim member 4, the snap ring being trans` 2;', versely split at 9. The main rim member 4 is slightly thickened as shown at to provide a surface slightlyV inclined to the outer 4 surface of the main rim member as indicated more clearly in Fig. 3.

The main bodyl or web of the wheel is composed of a disk having -upon Aits margin a rearwardl turned 'flange 11 upon. which seats the thickenedl portion 10 of the rim, which flange is connected with the main portion 'of the disk by an inclined iange 12 which bears against the A rear inclined face of the drop portion of the rim provided with the gutter 6. This-inclined ortion 12 connects with the zone 13ofthe isk, arranged at a slightly opposed -inclination and constituting a peripheral portion of the wheel disk. The peripheral zone 13 merges intoA a forwardly concavev zone14,'"and this zone merges into a hub zone 15 which is substantially parallel to the median wheel plane and aperture at 16 to take over the hub barrel 1.

The wheel disk is rearwardly reinforced by a plate 17, which plate may advantageously be of, non-circular and preferably.

5G rectangular form as the retention of the triangular corners, which would be cut away y and wasted if the plate were made circular, obviously eectsv additional reinforcement of the disk over an area within regularly spaced boundaries farther from the 4center interferes* with the lines of vibration and by their dissipation f disk,

of the -same than would be. the casefwith a circular plate made from the same metal ,maza

blank. Moreover, the Contact of such plate` with the wheel ampliiicationl of' noda tends to minimize noise in use. `The outer margin ofthe plate bears firmly upon the while aplurality of spaced pockets 19 are formed `in the plate and bear against the-rear face'ofthc plate margin. Inwardly of the pockets -19 formedfinto a flat zone 20 which lation to the disk, and 'still further inwardly disk over a non-circular area disk inwardly 'of the/4 the plate is dished intocontact with the disk Y in a narrow Zone 2l. A plurality of radial depressions 22 'are formedl in the zone 20of the plate as best shown in'full lines in Fig.

2 and in dotted lines in Fig. 1. These depressions act as stiening corrugations and spacersagainst -the thrust or compression of clamping nuts 23 of the stud the the hub. The

bolts 24 which and its reinforcement plate to sustain the disk' andplate apart main disk and the reinforcing plate ar welded or otherwise suitably Connected at Y.

the zones 16 and 21 and inthe lregion of 25 near the margin ofthe reinforcing plate A. clamping flange for transmitting the load from bolts 2l around the hub zone is prol .vided with its outer edge stilfened by curling as indicated by' 26 and itsl inner portion stiffened'by the swell 27 and withl its main portion 28 in Contact with the zone 15 of the 1 main disk. v

The reinforcing ldisk with its depressions l19 and 22 serve to compose a trussed conparts without the use at the Sametime furstruction between the of other pieces and nishes a verylight and cheaply made structure.

The main disk with its flanges 11 and 12 seated under the portionV 10. and inclined furnish a ,Very desirable seat for carrying the rim 4, and, in case the wheel is to be used only as a demountable wheel, the parts may be secured permantently together bythe rivets 37, see Figure 4.

When the wheel is used as a demountable rim 'wheel -I provide a side clampingV ring having the marginal Harige 29, body portions 30, and the inturned marginal edge 31, which 1.10'

is secured by a series of screws 32-passing in Figure 2 hasits apart from the main disk radially into nuts ,3 3 fixed bination with a reinforcing and stitfened across-this ,through the'body 30 on thering and screwed in the rear of the Zone 13 of the main disk.

he narrow seat 10 to the inclined portion 8 allows a snug iit for the rim on the disk 'and at the same. time provides clearance space for the removal of the rim after it has-been inclined slightly as is shownin VFigure?) the rim iseasily removed from thedisk how-v The locaever close the fit of these' parts'. tion of this surface, adjacentto the glitter e rim serves to furnish strength ,where needed and `facilitates lin some measure the rolling of vthe section.
