Abstract

619,718. Collectors. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Dec. 20, 1946, No. 37491. Convention date, Jan. 12. [Class 104 (iii)] A shoe or bow collector has an elastic pivot support in the form of a closed-force structure having front and back members which provide an elastic pivot point above the contact surface of the shoe. The members 32, 33 consist of flat springs inclined towards each other and secured to lower and upper members 29, 30. The shoe 11 is pinned at 31 to member 30 whilst member 29 is welded to a spacer 25 connected by flat springs 21, 22 to the pantograph head 23. In a modification, Fig. 3 (not shown), the springs 21, 22 are replaced by links pivoted at each end on elastic pivots, each comprising a sleeve and shaft with an intermediate sleeve of rubber vulcanized thereto. In a further modification, Fig. 7, the lower member 78 is bolted to a spacer 74 carried by pairs of flat springs 70, 72. The head 62 carries a rigidly mounted shoe 61 to prevent excessive deformation of the resilient mounts. The pantograph 15 has lugs 64 secured by pins 63 within elongated openings in the head 62. The spacer 74 may be connected to the lower member by an elastic structure comprising a plate bolted to the spacer and having elastic pivots mounted in blocks secured to the lower member.
