It is still another object of the invention to provide a multiepart cover assembly for disposi tion over the outer side of a wheel structure, said 50 and may be changed or modi?ed without depart ing from the spirit and scope of the invention as set forth in the appended claims. _ I . As will be seen from Figure 2, the wheel struc ture shown herein as being associated with an em bodiment of my invention includes a“ tire rim ill of the drop center type having a base ?ange H 2 2,380,241 to which is secured a central load bearing por- ‘ tion |2 by means of a ?ange |2a formed on the radially outer margin thereof, said ?ange being covere2l irom the rear side thereof and is pre . vented i'rom'separating therefrom outwardly by the circularly humped con?gurationzot the in riveted or welded to the base ?ange Ii. The central load bearing portion i2 is further provided with a radially inner bolt-on ?ange I3 termediate part of the cover 2|. With the fore going construction it will be seen that there is provided herein a multi-part cover assembly in which the cover parts are held securely together as a unitary-structure.’ In assembling the cover which may be secured in any suitable manner to an appropriate part of the vehicle such as the brake drum or the like. parts asshown in Figure 2, it is merely necessary The tire rim I0 is further provided with op 10 to align the radially inner edge of the cover part posite side wall ?anges H,,_opposite intermediate 20 with the bead 25 of the cover part 2| and on. ?anges l5 and opposite edge portions it between which may be disposed the'radially inner parts-of the axially inner side thereof, whereupon by axial outward movement of the cover member 20 relative to the cover member 2|, the parts a pneumatic tire including a ‘casing: if‘ltand an-v inner~ tube | 8 provided with a'Yalve stem '| 8 which may be aligned to extend through a suitable aper ture in the adjacent side wall ?ange H. The cover assembly ‘shown herein includes a radially router annular portion 20 and a central 1% may be disposed in the position shown. _ To the end that the above described cover as sembly may be retained upon the wheel struc ture, there is provided herein a plurality of spring clips 28. These clips are preferably arranged on the outer side of the central load bearing portion circular hub cap simulating portion 2|. The air- '~ ' t. nular portion 2|! is preferably formed from syn in I2 01’ the wheel structure in circular and circum thetic plastic sheet material or the like and ‘has 4_i'erential1y spaced relation to prescribe a circle physical characteristics enabling it to be self of such diameter that the head 25 must be sustaining as to form and yet resiliently, locally sprung over the clips in attaching the cover to the ?exible so that it may be de?ected and yet will wheel structure.’ Each of these spring clips in 25 snap back immediately into its original con?gura clude'a supporting arm 29 arranged for surface tion upon release of the ?exing pressures'there engagement with the adjacent portion of the from. The central cover member 2| is pref outer surface of the central load bearing portion erably formed from more rigid material such as _ I2 of the wheel. A part of or all‘ of each arm thin sheet metal or the like and is provided with ' 29 may be riveted or welded to the wheel as 30 a central crown portion 22, an intermediate cor-~ \ shown, at 36.
