Abstract
3636. Hollingsworth, E. M. Feb. 20. Electric railways and tramways with safety appliances for use in connection with overhead conductors. Conductors.-To enable any person to connect to earth &c. any charged wires in case of emergency, especially trolley wires on electric tramways, encased switches, operated by breaking a plate of glass or other fragile material, are provided at suitable points. Fig. 1 shows a switch b adapted to connect the supply and earth wires d, e, enclosed in a cage a and prevented from closing by a connection! to a glass plate g. In a modification, a weight attached to one lead is suspended by a cord attached to the plate and falls on to a contact connected to the other lead when the plate is broken.
