453,876. Vehicle wheels. BAKER, F. W., The High House, Oldswinford, Stourbridge, Worcestershire. March 16, 1935, Nos. 8231, 22358, and 24358. [Classes 144 (i) and 144 (ii)] A wheel comprises two axially-spaced sheet-metal discs connected by lapping their opposed radiallydirected outer edges, and shaped so that the peripheral portions form a single-thickness base, and at least one side-flange, of the rim. In the form shown in Fig. 1, the outer disc 10 is formed integral with the rim-base 16 and a portion 17 of the inner rim-flange, the latter being completed by the lapped edge 19 of the inner disc 11. The flanged centres of the discs are lapped and reinforced by ferrules 44 which receive the usual attachment-bolts 14. The outer rim-flange 21 is detachably secured by a split ring 23, the ends of which may be adapted to hook into apertures in the rim-base. To prevent axial displacement, the flange 21 may be fitted with a hinged plate 29 secured by a set-screw 31 engaging a threaded sleeve 33. The latter may also be utilized to receive the shank 35 of a tool (Fig. 3) fitted with a thrust-bolt 37 for forcibly unseating the flange 21 to release the locking-ring 23. The outer disc is formed with a cupped centre 39 closed by a cap 47 which is secured by a central screw 48. Fig. 4 shows a modification in which the disc centres are connected by a coned sleeve 54 which is secured on the coned permanent hub 12 by a central nut 51. Figs. 5 and 6 show a modified form of bolt-on type of wheel with a reinforcing disc 59. The detachable rim-flange 60 is a split ring with a beaded edge 62 engaging a groove 24 in the rim-base. One end of the flange is fitted with a stud 65 to engage an aperture 66 in the rim-base, the other end having a swivelling stud 67 which is apertured, or slotted, for the passage of a draw-bolt 63 pivoted on the rim. In further modifications, both rim-flanges are formed on one of the discs ; and, wood or fibre packing is fitted between the centre-portions of the discs. It is also stated that the cap 47 may be secured by two diametrically-opposite screws on one of which it may be swung to give access to the wheel-attachment nuts 15 ; and, rubber bushes may be fitted to the disc-spacers and the central closure-cap.
