" clear. and eract description thereof, refer- ""causes'the wheel to operate successfully and ence being bad to the accompanying drawings, in which like letters refer to like parts.

The object of this invention is to provide an improved construction of vehicle wheel which is resilient enough for automobile use and may have an entirely puncture proof tire and is capableof standing up to the work which would be required in an auto- 1 ,7 on and b mobile.

A feature of the invention consists in providingfwithin the wheel afioating structure which carries the axle and-load and which is SllppOIl'Qd by a plurality of pneumatic annual cushions located within thewheel, the inner portion of each annular cushion being clenched in an annular metalrim which is U-shaped in cross section and one of a series concentric with the tire rim and likewise concentric with a solid rubber tire surrounding said rim. A portion of the outer part. of each annular cushion is embedded within the annular metal or tire rim which enveloped. by the solid cushion tire,

the inner edge of the solid cushion tire being on about the same level as the inner edge of each annular cushion. outer portion of each pneumatic annular cushion adjacent to the tireis located with reference to the solid rubber tire in sub "stantially the same relation as the inner pneumatic tube located with reference to the outer casing of the pneumatic tire. This it overcomes the danger of lateral thrust or strain as when an automobile turns a corner under speed.

l'&nother fQZlllll't' ot' the invention is that each annular cushion is supported by an external rim which. in the present. instance, is associated with the cushion by clenching flanges. but, of course, may be associated therewith in any other suitable manner. The several cushion supporting rims are arranged. in a circi'ilar series within the outer tirc rim and means is provided for prevent- -.*ing relalive rlf lling. The circular series of cusi i n supp-.:rting rims is also held in place There fore, the

by a central ring or member which contacts therewith in such manner that the central member-and the circular series of cushion supporting rims are firmly nested within the tire rim, said tire rim being under cir- Another feature of the invention consists 3 in forming the clenching rim of each pneumatlc cushion of two annular side portions or halves and they are forced and held together b the recessed portion of the metal rim on t e outer side of each annular cushv a pair of oppositelylocated wedging camping plates or rings on the inner side and by'a pair of oppositely lo- 'cated wedging clampingl braces. at points about midway between t e outer and inner sides of the annular cushion, these wedging members serving to firmly nest the cushion-supporting rims within the tire rim so as to produce a unitary structure.

Another feature of the inventon consists in,t he particular means for mounting the load so that it will be carried by the inner peripheries of the annular cushions. An other clencher rim is provided within each cushion which is held together by clamping portions of a pair of plates which supports the load.

Another feature of the invention consists in making a dust proof joint between the side plates and the movable parts of the wheel so that no dust can get therein.

The full nature of the invention will be understoodfrom the accompanying drawings and the following description and claims:

In the drawings, F igurc 1 is a central cross section through the vehicle wheel, showing the intermediate parts in elevation. Fig. 2 is a section on the line 23 of Fig. 1. Fig. 3 is a transverse section on the line of Fig. 1. Fig. i is an end view partly in section on the line 4-4 of Fig. 1. Fig. is a radial section on a larger scale of a portion of the wheel through the joint between the inner and outer frames. Fig. 6 is a transverse section through a part of the inner portion of a cushion and the means for clenching it.

in detail the drawings herein show wheel. having a continuous annular metal tire metal. rim 10, whereby seidfparts are readily secured together. Y

Wit in theforegoingstructure formed of the si .e casings and tire of the wheel, there is a floating frame Whlfih Cttl'l'lGS the load; Saul floating frame cons1sts of s de bars 20 which extend radiellyof the hub and. they arearranged in pairs, carrying bolts 21 at their inner ends which are adapted to be secured to the sxlewhich is not here shown. Between the outer ends of each pair of bars 20 an annular pneumatic cushion 22 is mounted. To that end the inner periphery of each annular cushion 22 is thickened. and the thickened portion thereof clenched. by arimcomposed of a pair of oppositely placed clenching rings 24: which lie between portions of the bars 20 and the latter are clamped against the clenching rings 24 bybolts To that end the bars 20 are shaped, as shown in Fig. 3, so as to lie against the pair of clenching rings 24 and bear against themwhen drawn. downfhy the bolts 25 so as to cause said rin s 24: to

clench and hold the inner peripheries of the pneumatic cushions. v

. The outer periphery of each pneumatic cushion is thickened. to form a rib which is clenched in an annular clencher rim formed by clencher rings which surround the and clamped together by the curved edges 33 of a pair of annular plates iliwhichare drawn and held together for clumping by bolts 35,.{15 shown in Figs. 1 and 6. Therefore, the two annular plates 34 When drawn together by the bolts 35 will constitute a centrelly located uumilar member with laterally turned edges which engage the adjacent portions of the outer peripheries of the series of the annular cushion clenchcr rims and oouu'iress said series of o llOil clouche'r rims between the outer tire mm 10 and. said centrally located member 34. This nesting of the several arts to compose the main wheel structure p aces the older tire rim under tension and the cushion rims and crzi'itral member under compression and ash consequence the main body of the Whoch while very light, is, nevertheless, exceedingly strong and entirely free from those stresses tending to breakage, which would necessa rily occur in a cast wheel huvin cushionpockets. My stri'utrturo is also those weaknes es which would necessarily result from the cutting of cushion pockets in plates or disks forming the main body' of the wheel. Said clemrher rings 30 are also held in place and clumped on cash side of each. cushion by intermediate brace bars 36 which'hare end flanges that partially envelop the ringsrlll and are drawn together and clamped against said rings 30 by a bolt 37, see Fig. ,2.

Hence, each pair of clencliw rings 30 are clamped and held in place et four points,

see Fig. 1, whereby the periphery of eech bolts 21 and formed as shown in Fig. 5', and

there a plate ll extending around the in-- uer reduced portion of the brake drum so that said plate i1 and thebrake drum OVG1E- lap soul plates is closed by ieltin place byrivets 41-3 on. the le plate 15. This makes the Wheel (lust proof so that dust cannot cuter-the interior thereof.

The pneumatic cushions Q are inflated through air tulu-.s--l5, see 1, which the side plate 15 and the i ips hold Free from.

tend from" the several cushions to a point near the'center of the Wheel where they are readily accessible.

In operation the series of eireushio s 221 cooperate for yicldin zly supporting the load and floating" inner frame within the outer casing or frame of the Wheel so that all shock and jar will be taken up by the cushions.
