DISK WHEEL.

Specification of Letters Patent. I Patented J 11119 21, 1921,

Application filed November 7,1919. Serial No. 836,337.

which it appertains to make and use thesame, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form part of this specification.

Like figures of reference refer to like parts.

This invention relates to disk wheels for vehicles.

One of the objects of this invention is to provide a disk wheel wherein a single sheet of metal forms the wheel disk, which forms the function of spokes, the felly of the wheel and part of the rim thereof.

Another object is to provide a sheet metal disk wheel havin sheet metal reinforcing parts about the hu which are of such shape as to easily lend themselves to the processes of sheet metal stamping. And a further ofject is to provide an auxiliary disk in connection with the main disk of the wheel, which auxiliary disk is provided with a peripheral recess adapting the peripheral edge of the auxiliary disk to abut against the surface of the main disk, and also to have the recess contain some impervious material which shall serve to exclude water from between the main disk and auxiliary disk.

The form of disk wheel which is the subject of this application, is an improvement on the one which is the object of my application filed Aug. 23, 1919, under the Serial Number 319,396, and differs particularly therefrom in the fact that in this invention of a disk wheel, part of the rim, the felly and the main disk are all incorporated in one sheet of metal.

' With these and other objects my invention consists in certain features of construction,

one embodiment of which is illustrated in the drawings, is hereinafter described, its construction is explained, and what I claim is set forth.

In the drawings,

Figure 1 is a front plan view of a vehicle disk wheel embodying my invention, having part of the wheel broken away to more fully illustrate its construction.

Fig. 2 is a section of the wheel shown in Fig. 1, taken on the line X X thereof.

Fig. 3 is a perspective view of one of the bridging pieces used to reinforce the felly at the bolt connection of a rim part. L Fig. 4 is a plan of the auxiliary reinforcmgrdisk. I

ig. 5 is a, section taken on the line X--X of Fig. 4.

Fig. 6 is a plan of the backing plate.

Fig. 7 is a section taken on the line X-X of Fig.6.

Fig. 8 is a plan of the spacing and reinforcing rin'g.

Fig. 9 is a section taken on the line X--X of Fig. 8.

F ig. 10 is an enlarged section of the spacing thimble used between the auxiliary disk and the backing plate at the clamping studs.

Fig. 11 is an enlarged section of the flared portion of the felly and rim at the bolt hole.

Fig. 12 is a section of a modified form of rim to that shown in Figs. 1 and 2.

In the figures, there is shown the usual form of axle 1, upon which the wheel is mounted, shown having a hub formation 2, of the Ford type, held upon the axle 1, by the nut 3. The cap 4 in threaded engagement with the hub 2, covers the nut 3. Bolted to the flange 5, by the bolt 6 is a brake drum 7, which bolt 6, with five others firmly secures a hub bed' plate 8, to the flange 5. This bed plate 8, has an angular recess at 9, against which is fitted an auxiliary disk 10, having also a bearing at 11, against the bed plate 8 near the hub 2. There. is a cylindrical portion at 12, having a bearing on the bed plate 8. This disk is stifi'ened by radial ribs 10*. At the periphery 10 of the disk 10 is an annular recess 10 filled with an impervious material 10 acting as a seal between the main and auxiliary disks to exclude water therebetween. A reinforcing plate 13, co-fitting the auxiliary disk 10, near the recess 9, is provided. This reinforcing disk has a flange 14, which together with the cylindrical portion 15, of the auxiliary disk 10, forms an abutment for the inner part of the main disk 16, which is forced in contact therewith, by means of the circular clamping plate 17, held in place by the stud 18, with the nut 19. The stud 18 has a head 20, fitting into a recessed portion 21, of the bed plate 8. A stud 18 is provided with a thimble 22, having a flange 23. Part of the thimble '22 is partly in threaded engagement with the stud 18, and is screwed down tight, shouldering against the bed plate 8, to assist in holding the stud in place on the bed plate 8, and acts as a spacer between the auxiliary disk 10, and the bed plate 8, where the studs 18 pass through to enga e the nut 19, and also to form a rigid backing to the gether by the nut 19. There are three of these studs 18 equally spaced about the hub. The main disk 16 is shown in section to have an annular pocket 24 on the front thereof, from which the metal diverges peripherally. The metal is shown to extend peripherally beyond the pocket and to turn in the opposite direction forming an annular pocket 25 on the rear side of the wheel, and in so doing, there is formed a felly for the wheel.

The metal continues peripherally until part 26 of the rim is formed. Coordinated with the part 26 of the rim is the rim ring part 27, which is bolted to the felly 25, by means of bolts and nuts 28 and 29, respectively, the

heads 30 of which bolts pass through the body of a bridge iece 31, which bridge piece 31, is electrically welded into place 1n the telly 25. A cotter pin 32 is provided to secure the head 30 from turning within the bridging piece 31. There is also provided a tube 33 incorporated in the felly portion 25 In Figs. 1 and 2 is shown a clencher or inturned flange form of rim, while in Fig. 12 the section shows the rim flanges 26 and 27 flared outward.

It'will be noted that the principal part of the rim is shown as integral with the an and main disk, and that the form herein shown in section, lends itself easily to the operations of stamping; Where the ring 27 is incorporated with t e shown, in enlarged section in Fig. 11, at the holes provided for the passage of the bolts 28, out-turned flanges 25", upon the telly ortion 25, which flanges 25 co-fit into the anges 27 on the ring 27. The flanges 25 on the felly portion 25 do not project all the way through the flanges 27, thereby rmitting the nut 29 to have a full bearmg upon the edge of the flange 27 only, in drawing the parts together. These flanges 25' and 27?, interfittin'g as they do, relieve the bolts 28 of all transverse strain. Modifications of the one embodiment of my invention herein shown, may be made without departing from the spirit and scope of the said invention. I therefore do not wish to be confined to this one embodiment.

Having described my invention, claim, 1. In a sheet metal disk wheel having a parts which are drawn to 'felly 25, there are fixed to said flange, an auxiliary disk in shouldered engagement with said backing plate, a main disk spaced from said auxiliary disk at the contact of the latter with said backing plate, and in fixed contact with said auxiliary disk near its periphery, a reinforcing ring between said main said auxiliary disk to strengthen the said wheel in abuttingrelation of the parts, a clamping plate concentrically positioned upon said hub, in bearing contact with said main disk, having a diameter suflicient to have a direct bearing opposite said reinforcing ring and said auxiliary disk, means holding said bearing and said backing plates in clamped relation.
