Abstract
28,745. Swinehart, J. A. Dec. 31. Tyres, elastic other than pneumatic; felloes or rims.-Rubber tyres are provided with means for heating the tyre, or a material therein, to alter its consistency and sc facilitate the securing of the tyre in the rim or its removal therefrom. The means can also be used to form a core of sponge rubber, with air cells, inside a tyre. The rubber tyre A has a dovetailed groove 2 round its inner surface, and grooves 3 to take the edges of the flat-bottomed rim. Wires or nails 8 are driven into the tyre at intervals to strengthen it. The groove 2 is filled with a fusible cement or other material which can be softened by heat. The tyre is pressed into the rim while the cement is soft. When the cement hardens, it locks the side portions of the base of the tyre within the rim. To remove the tyre, the cement is heated by passing an electric current through a wire or band 10 in the groove, the terminals 11 of the wire extending through the rim. The wire 10 may be replaced by a tube which is heated by steam or otherwise. Instead of using a material which softens on heating, the groove 2 may contain uncured rubber, rubber cement, or other material, which is hardened by heating, as described above, after the tyre is in place in the rim. A tyre with a large number of air chambers or cells is obtained by heating a wire or tube which is arranged in the tubular tyre and surrounded with uncured sponge rubber.
