IN their search for a practical aiUomnliiU wlicel with the resili-ent qualities of the pneumatic and without its disadvantages,inventors have brought out numerous designs embodyingspring hubs, spring spokes and spring rims, the majority of which with a slender rod projecting down into the tube a certain dis-stance, and when the tire becomes sufficiently deflated so thatthe tread is pushed against the rod, the rod is pushed into thevalve and causes the whistle to Ohlsson Spring and Rubber Block Tire. have proved either too expensive to manufacture in competitionwith the pneumatics, or impractical in actual operation. Here, how-ever, is a wheel of entirely new design, which lays claim to atlast having solved the problem. It has been examined in opera-tion by a representative of the India Rubber World^ and seemsto uphold the contentions of the designers. A good idea of theconstruction of this tire may be gained from the has a solid rubber tread consisting of rubber blocks, eachattached to a steel plate so that each plate and block is inde-pendent of the one adjacent to it. In the center of each plateis a depression or groove, so that when all plates are placed endto end a continuous channel is formed around the this channel runs a flexible, endless steel cable whichbinds the blocks securely together, resists the pressure of thesprings and allows the tread to weave over the road, regardlessof th
