Abstract
2311. Dawbarn, R. A. Jan. 30. Electric contact-arrangements, operation of by passing collectors.-The supporting-ears for the overhead conductors of electric tramways are adapted, on the passage of the collecting- wheels, to be raised for the purpose of operating switch devices, which close electric circuits from the trolly wire to apparatus for operating points, signals, &c. Fig. 3 shows one arrangement in which, upon the raising of the conductor a and its supporting-ear h, the box d is oscillated and the circuit k, j momentarily closed by mercury therein. After the passage of the collector, the switch is again opened by the weight of the parts. 'Other forms of tilting mercury switches are also used. The weight of the conductor a is balanced by the weighted levers n, or the ear is carried by springs from the transverse cable b. In the modified arrangement shown in Fig. 5, the circuit is completed through the contacts p, r on the raising of the supporting-ear.
