438,173. Endless tracks for vehicles. GOODRICH, CO., B. F., 230, Park Avenue, New York, U.S.A.-(Assignees of Mayne, R.) Jan. 5, 1935, No. 446. Convention date, Aug. 4, 1934. [Class 79 (i)] An endless track comprises parallel strands of wire cable 11, or other inextensible fl e x i b l e members, and a plurality of cross-bars 12, 12<1> clamped to the cables at regular intervals but held completely out of contact therewith by an intervening layer of rubber, these cross-bars being adapted to engage a driving sprocket. The intervening rubber layer may comprise rubber belts in which the cables or the like are embedded, and to which the cross-bars are clamped. In the construction shown the cables 11 are embedded in two parallel endless rubber belts 10, 10<1> connected together by the cross-bars 12, 12<1> which are vulcanized to the cables. Bolts 13 clamp the cross-bars together and also secure thereto plates 14 engaged by the driving sprocket 16 and having side guiding members 15 which overlap those of adjacent plates and thus limit lateral flexing of the track. The sprocket 16 is secured between flat pulleys 17, 17<1> on which the belts 10, 10<1> run. In a modification the sprocket teeth are double and the guide members 15 are disposed in the middle of the plates 14 and between the sprocket teeth. |
