Abstract
5425. Walker, J. H. March 4. Electric railways and tramways with overhead conductors. Collectors.-The fork or "harp" which holds the trolley wheel on the end of the pole is in two parts A, B, riveted together, with spring arms for the bearing at - - one end and a socket C at the other for attachment to the pole. Each half may be in one piece, as shown in Fig. 1, or built up of plates and wires B', C', D<1>, socketed and riveted together, as shown in Fig. 5. The arms &c. are curved to act as guards. The spring fork carries the caps 13 in which the spindle is held by pins 14, 15. Inside each cup is a spring washer secured by its topthickened edge a<3> and having a central spring portion a<1> and a stud a<4> to bear on the trolleywheel to transmit the current. An oil receptacle 30 is formed in the trolley wheel, and communicates with the bearing, which is fitted with a coil and filled with graphite between the bushes 33, 35 in the wheel and on the spindle, respectively.
