' v This invention is a disk wheel for use on vehicles and while particularly directed to disk wheels embodying two or more disks is equally applicable toddilsgk wheeLponstruction A common form of disk wheel now on the market embodies two disks, which are spaced apart at their centers by spacing means positioned between the disks, so as to lend lateral strength to the wheel and at the same time provide 'roper disks and the ub of the wheel.

A. further reason for spacing the centers of the disks apart in some disk wheels is to permit of their substitution for wooden wheel.

spokesuponthehub of aconventional wooden wheel, this being desirable wherever possible to obviate the necessity of constructing specialv hubs for the disk wheels. The reason for spacing the centers of the disks a art in wheels used on conventional wooden ubs is to permit of the employment of the hub bolts used to maintain the wooden spokes in place. When the centers of the disks are spaced apart as described, the same distance as the thickness of the wooden spokes at the hub, the wooden spokes may be removed and the disk wheel readily substituted on the hub. therefor and secured in place by the bolts. I I When the disks of a wheel are spaced apart at their centers for any of the reasons spec1-- f positlon,

fied, means must be provided for accomplishing the spacing of these parts of the disks.

This means is invariably in the form of a" separate and independent member or members ositioned between the disks and intende to rigidly space them apart. en such means is positioned between two disks, it is diflicult to firmly screw such means in so as to avoid rattling and other detrimental features and in the event of breakage of such spacing means, it is practically impossible in amajorityof structures to properly repair the same.

oregoing considerations in With the mind, the object of the present invention is to provide means whereby the spacing apart off the disks o'f' 'a two centers is not present in this structure,

disk wheel. at their bearing between the hub)- but,

in contra-distinction, when two disks are employed they are brought into face abutting relationat their centers -andseparate and independent means is positioned exteriorly of the disks for imparting to the wheel the desired thickness or dimensions at its center.

The present invention is so comprehensive in its application, that it may be carried out in wheels embodying but a single disk provided at its center with filler means so associated with the disk as to impart the desired central dimension thereto whereby a single disk wheel may be readily associatedwith the conventional wooden wheel hub as readily as a double disk wheel embodying the present invention.

A marked advantage of a wheel embodying this invention is that it is strong and durable in construction, may be economically and efficiently manufactured and is durable in use.

Features of the invention, other than those specified, will be apparent from the hereinafter detailed description and claims, when read in conjunction with the accompanying drawings.

The accompanying drawings illustrate diifer'ent prac ical embodiments of the present invention, but the constructions therein shown are to be understood as illustrative, only, and not as defining the limits of the invention.

In practice, the wheel of the present invention may partake of a large number of different forms. The invention may be em bodied in a wheel having a single disk and is equally applicable to wheels formed with two disks. The manner of securing the disks to one another at the outer margin or mar gins, as well as the manner of mounting the rim on the disk or disks, forms no part of the present invention, and in its commercial forms, the wheel may embody disks of different radial section.

.The invention relates directly to the hub portion of a steel wheel embodying either one or more disks and in the accompanying drawings, 1 have shown a purely illustrative structure, which is to be understood as in no- Wise defining the limits or this invention, which is directed to obtaining proper thick ness or.dimensions of a diskwheel at its center or hub portion.

Tn the accompanying drawings, several ways of obtaining thisrresult are shown, all of which ways entirely overcome the dis advantages inherent in structures wherein two disks are spaced apartat their centers or wherein one'disk is given the desired thicln ness at its center by providing spacing blocks at both sides or" the disk.

Referring to the illustrative showing in the drawings, and more particularly to the construction as illustrated in Figures 1, 2 3, 15 designates any suitable and conventional form. or rim which is spaced from a hub 16 by two disks 1'? and 18, These disks may be of substantially the same diameter, i. e., both the entire distance from the hub to the rim, or th'e'hub may be spaced from the rim by a singl disk which extends he entire distance the hub to the rim and has associated therewith a my copending application, Serial No. 319,091, filed August 22nd, 1919, on pressed steel wheel. However, for the purpose of illustration, two disks of the same size are shown. The hub 16 may be of any conventional form, such for example as is in common use in connection with wooden wheels of the conventional kind. Such a hub is provided with a fixed flange 20 and a removable flange 19, which flanges are bolted together by hub bolts 21 and in ordinary practice serve to clamp the spokes of a wooden wheel between the fixed andremovable flanges 20 and 19.

in carryin out the present invention in a wheel embodying two disks, which, in practice, are preferably dished substantially coniplementary to one another, the outer disk 17 is constructed in the usual way, but the inner disk 18 is formed at its center so that an appreciable part of the portion of such disk which .is marginal of the central hub opening thereof will lie in face abutting contact with the adjacent or opposed face of the disc 17, as shown at 22. In other words, the central portions of the disks or those portions thereof immediately surrounding the hub opening are in face abutting relation to one another and are not spaced apart as heretotore.

In order that a wheel so constructed may have proper thickness or dimensions adjacent the hub, 1 preferably associate with the construction already described a member 23 which niay be graphically termed a tiller as it serves to cooperate with the discs in filling out the space between the fixed and removable flanges 20 and 19 otthe hub. This filler may be conveniently formed after the manner shown in Figure 8, wherein it is illustrated as embodying a tubular section 24;- provided at one end with a radially extending flange 25., In assembling the parts of the wheel, the filler 23 is brought into the position shown in Figure l and is secured in this position in any suitable and convenient manner. F or example, the filler may be firmly welded in place as shown at 26 and 2?. To facilitate the welding operation the outer margin of the flange 25 of the tiller to the plate 18, and also to render the inner surface of the wheel smooth and tree from projections, the plate 18 be ohset at 2'? so as to provide a depression in the tapered face or the inner plate 18 under which the flange 25 oi the filler loosely seats. A fillet of metal as shown at 26 be conveniently deposited between the outer margin of the iiange 25 and the ofifdncc ' 1, 2 and 3, the inner margin o these parts.

' circumference of the sleeve-like portion 24 I formed in all . tirely fill such space as the filler. This construction is preferable as it produces a strongand entirely satisfactory union when welded as described, although, if desired, this construction may be varied as shown in Fig ner margin of the disk 18 is formed the same as the inner margin of the disk 17 and the free end of the sleeve 24 of the filler is flare out at 29. In such a construction, the parts are welded together as shown in Figure '5. The two described ways of securing the sleeve portion of the filler to the inner margins of the disks 17 and'18 have been found to give satisfactory results in practice, but it will be understood that they maybe nnited in other ways than as shown and through other means other than welding without departing from this invention.

A wheel constructed as described is adapted to be slipped over the hub of a conventional wooden wheel, suitable form of hub, and secured in place by the hub bolts which are adapted to pass through alined holes formedin the disks and in the flange of the tiller. Figures 1 clearly shows holes 30 provided for this purpose, the face abutting portions, of the disks 17 and 18 and alined holes 31 formed in the flange 25 of the tiller.

It may be here noted that whens wheel so constructed is mounted on a hub and the hub bolts tightened, the sleeve-like portion 24 of the filler will take the greater portion of the tension imposed upon the construction by the hub bolts, forced against bending of its respect to its sleeve portion 2% by 32 of the disk which extends transversely of the wheel and from the base of the depression in which the flange of the tiller seats to the portion 22 of the disk 18, which is in face abutting relation to the center of the disk 17. The construction is strong and rigid and no strain that can be placed thereon by the bolts 21 will be suihoient to disrupt the parts.

, However, if desired, the structure may be "further reinforced by positioning a core 33 of wood or any other suitable material with in he space left between the center of the dish 18 and the flange 25 of the filler sitter the mart ner shown in Figure 6. This core may on shown.

1 am aware, moreover, that instead of using and the filler will he therefore reinflange 25 with I a metallic filler such as shown in Figure 8, the

desired, the holes in filler may be made entirely of wood, fibre or other suitable substance to the exclnsion oi metallic parts and may be made solid and associated with the disk 18 after the manner shown in Figure Y, wherein the tiller is described by the reference character 23. ii the tiller 23 through ure 5, wherein the 1nor for that matter any other the P0111011 tire nipple is adapted to which the hub bolts pass may be lined with a suitable bushing 34, metallic or otherwise, but this is not necessarily essential. urthermore, in the device of Figure 7, the parts are not shown as secured together though the disks may be welded, riveted or otherwise attached to one another and the filler 23 may be held in position in any desired way.

In order that disk wheels of diflerent sizes which may net may be associated with a hub,

' I may use in necessarily be of the same size,

d conjunction with the wheel of this invention,

a bushing 35shown in Figure 9, which bushing may be of wood, fibre, felt or any other suitable material so as to absorb shocks to which the wheel may be subjected. However, this bushing may be of metal if desired. The manner of associating the bushing with the wheel and hub is shown in Figure 10 and it will be understood that in practice bushings of difierent sizes may be employed so as to enable the dimensions than that for was built. I

In the foregoing discussion of the invention, the same has been dealt with in conjunction with wheels embodying two disks, but itwhich the wheel wheel to fit over a hub of smaller is to be understood thatit is equally applicable to wheels embodying a single disk. In Figure 42, a filler oi the character shown in. Figure 8 is associated with a single disk 36 and its flange is'shown as riveted at 37 to the disk, while its sleeve portion is illustrated as welded at 38 to the inner margin of the dish. Any of the other forms of the filler member than the metallic form shown in Figure t may be employed with a. single disk without departing from this invention.

One ofthe most marked inconveniences inherent in the employment of disk wheels as now made is the inaccessibility of the tire nipple which is so positioned thatin many inllll wheel construction is illustrated wherein the parts are so formed that the nipple is in a convenient and accessible position from the outside of the wheel. This end is accomplished by stamping out a recess from the inside oi: the outside disk 17 so as to provide a fiat abutment portion 39. This portion is provided with a nipple hole 40 in alinement with a nipple hole 41 in the rim l5 and the project through the alined holes 41 and t0 and into a convenient accessible position. The cap 42 of the nipple 4:3 may be easily screwed on and removed from the nipple and the outer end of the latter partakes of a position wherein it is readily accessible from the outside 01 the wheel. this is an important feature in disk wheel ree ' ner as the disk 17 b construction and overcomes advantage in disk wheels.

In the formation of the disk as shown in Figures 11 and 12 no pockets are'left on the outer face of the disk for the accumulation of dirt and mud, and the wheel may be washed as readily as though the shoulder portion 39 were not formed therein.

The construction of Figures 11 and 12 may be carried out in double disk wheels, as well as in single disk wheels, and is accordingly not restricted to the specific showing of Figures 11 and 12. Thus in Figure 13 I have shown this feature incorporated in a double disk wheel comprising two disks 17 b and 18". The disk 17 is constructed in the same manof Figure 12 and the disk 18' is merely added to this construction. The tire nipple is shown at 34 and the opening for such nipple is illustrated at 40. r

It will be apparent from the foregoingdethe long felt disscription that the wheel of the present in-.

vention embodies several features of novelty, which when combined in a wheel result in a structure of pronounced utility, economy and efficiency. It will be understood, however, that some of the features enumerated may be employed in wheel construction without necessarily employing all. Accordingly, the present invention is to be construed as broadly novel as is commensurate with the appended claims.

Having thus fully describdd the. invention, what I claim as new and desire to secure by Letters Patent is:
