Abstract

25,481. Donkin, J. Nov. 18. Felloes or rims; tyres, pneumatic etc.; spring wheels.-A resilient tyre for motor and other road vehicles comprises an elastic or extensible membrane c stretched across a trough-shaped rim band secured by continuous rings d in combination with the clips e<1> and tightening-bolts e. The channel of the rim may contain an inflated member h, a suitable packing h<1> being inserted between the tube h and the rim, or solid elastic members ; or the edges of the membrane may be vulcanized to the sides of the rim, thereby constituting an air-tight chamber which can be inflated. The membrane carries a laminated tread f, comprising layers of wood or the like made up in one length or in separate hoops, and secured together by marine glue or other suitable cement and screws. The tread is provided with a metal ring g and is secured to the membrane by the sleeve bolts f<1>, f<2>. Creeping is prevented by corrugating the edges of the rim and the contiguous surfaces of the membrane, or the latter may be covered with a coarse material such as netting or open-work canvas.
