Improvements in and connected with Wheels, applicable to Motor Cars, and other Vehicles.

Реферат: 23,240. Silverwood, T. A. Oct. 27. Disc wheels; spring wheels; hubs; tyres, pneumatic, &c. ; felloes or rims.-Disc, artillery, and spiderwheels, for motor cars and other vehicles, are, in one form, keyed to a metal tube which forms part of the hub. The disc-wheels are provided with springs, and comprise discs d, arranged between a sleeve g and flanges h, which, together with the sprocket-wheel i and brake drum j, are fixed on the steel-lined tube f by a key extending the greater part of its length, and all bolted together. A collar on the tube fits a recess in the inner flange, to prevent lateral displacement of the wheel on the tube. Blocks m on the sleeve g receive screws k on which are adjustably mounted triangular frames e extending round the wheel. Pins at the corners of these frames work in slots in links n, to which rocking plates y are pivoted. Bow springs 1, the compression of which can be varied, are arranged next to the tyre and loosely attached at their ends to the forked ends of the rocking plates. Ring plates a, bolted to the discs, are grooved to take packing-rings b, which secure the detachable tyre and exclude dust and moisture from the interior of the wheel. When a cushion tyre is employed, the packing-ring is dispensed with, the grooves receiving the heel of the tyre. Iron and pneumatic tyres may also be used. The discs are kept at the proper distance apart by sleeves on bolts c. In fitting an artillery wheel or a spider-wheel on the tube, the wheel is bolted between the flanges h, the sleeve g not being required. The frames e and rocking plates may be replaced by bow springs o, as shown in the lower part of Fig. 1. A continuous ring w, Fig. 19, may be used instead of the sleeve g and blocks m, in which case two additional flanges v would be provided and the tube f dispensed with. The bow springs may have one end hinged to the frame e, the other end being left free, as shown in Fig. 9.
