Abstract

28,768. Andersen, J. M., and Anderson, A. Dec. 30. Electric railways and tramways with overhead conductors. Relates to insulating-supports for the trolley wires of overhead electric railways, where the trolley wire is divided up into a number of sections, insulated from one another. The line terminals a, b are made interchangeable and capable of being readily connected to and disconnected from the other parts of the support. Each consists of a casting having a body portion 10, with straight undersurface, and an upwardlyextending hollow portion 12, in which the trolley wire is secured by a grooved clamping-plate and screws 19. It is detachably secured to a head-piece 28 or 40 by means of lugs 24, 25, which are engaged with notched or recessed flanges 30 on the lower part of the head-piece. The two head-pieces 28, 40 are connected by insulators 43, 50 to a centre-piece 45, constructed in two parts secured together by bolts. The line terminals are connected together by a bridge-piece 51 provided with auxiliary terminals 52, which enter slots in the line terminals and are secured by cottar pins 58 ; the two head-pieces may also be connected together by a wooden or other insulator 60. The centrepiece is supported by a swivelling cross-bar 63 through which passes the span wire. The clamping-plate for securing the trolley wire in its terminal is given a suitable curvature, and forms an extended bearing for the wire, thus preventing concentration of the vibration.
