6755. Simms, F. R. March 15. Tyres, pneumatic; felloes or rims.-The cover b is built up. of alternate layers of rubber and canvas, and has flanged edges b<1> which take into the side recesses e' of an auxiliary rim e, the whole being screwed or otherwise secured to the edges a' of the semicircular rim a. The auxiliary rim divides the space between the rim a and the cover into two parts, which communicate through holes f. The inner space is fitted with an air tube d split along its outer periphery, while the outer space is made airtight (except for the holes f) by soft rubber or similar side pieces g. After puncture, the wheel runs on the auxiliary rim, and thus prevents damage of the air tube. The auxiliary rim may be dispensed with, the cover being then directly attached by a flexible band or other means to the rim edges a<1>.
