Abstract
862,681. Air-break switches. BRITISH INSULATED CALLENDER'S CABLES Ltd. June 20, 1957 [June 21, 1956], No. 19286/56. Class 38 (5). [Also in Group XXXVI] An isolating switch particularly for controlling sections of electrified railway has a blade 12 electrically connected, by contacts 24 to a pin 21 carrying a cable terminal 52. The blade 12 is fixed to a bar 13 and an insulating plate 14 mounted on the cap 15 of an insulator 3 which is rotatable relative to the pin 21 to operate the isolator. The pin 21 is supported in bearings 37, 50 in insulating plates 14 and 47 held apart by pillars 40 screwed into the cap 15. The pin 21 has two flats 56 which can be engaged by a spanner for removal of the terminals 52. The contact sets for engaging the blade 12 and two sides of the pin 21 are similar and each comprises three blocks 24, with silver inserts 30, mounted on the end of fingers 20 projecting from a strip 23 mounted on each side of a projection 18 of the bar 13 or of the support memher 61 on the fixed insulators 1 and 3. Each block 24 has a projection 26 engaging a spring finger 27 of a plate 28 spaced from the strip 23 by a plate 34 but secured by the same bolts 32 and nuts 33. The pin 21 is coated with silver and the blade 12 has silver inserts 60. In Figs. 3 and 4 (not shown) the contact sets on each side of the pin and blade consist of only one block 24 and spring finger 27 and the bushes 37, 50 are of insulating material with a single metal member replacing the parts 13, 14 and the plate 47 is also of metal.
