14,664. Ducasble, A. June 29. Tyres, elastic other than pneumatic.-A rubber or like tyre is formed with a number of isolated chambers b which are plugged at the rim and are in connection with the atmosphere by small holes c. The tyre has a series of transverse grooves d which serve to allow that part of the tyre between them to be compressed without great compression of the rest of the tyre and to prevent slipping or skidding. The tyre is fastened to the rim in the usual way, while, for greater security, T-bolts may be used.
