Abstract
571,073. crossings for conductors. BRITISH INSULATED CABLES, Ltd., LONDON PASSENGER TRANSPORT BOARD, BROOM, T. C., and WILKINSON, T. Feb. 4, 1944, No. 2108. [Class 104 (iii)] An overhead conductor crossing comprises two pairs of tongues 3 ... 6, each pair being connected together about one pivot 35 and the pairs moving together in opposite directions. Each pair is connected by a bridge 20 having a stud 21, the studs being symmetrical about the centre lines AB, DE which intersect at E, the studs working in arcuate slots 23 in the crossing so that the tongues 3, 4 align with the fixed rails 1a, 1b or the tongues 5, 6, with the rails 2a, 2b. The pivots 35 are connected by a bar 33 carrying a screw 36 to secure a cover. The studs 21 are carried by cranked arms 26 having projections 41 which engage stops 42 to limit the movement of the tongues. Each arm 26 has an arm 32, the arms 32 being coupled by an adjustable link 30 so that the pairs of tongues move in unison. The fixed rails have grooves 9 on their upper faces to receive clamps for the connecting conductors, the clamps being secured by bolts and screws passing through holes 19. The tongues may be loaded by a spring &c. for one route.
