Abstract

400,702. Air-break switches. STEWART, J. E., 14A, Eton Road, Hampstead, and NORTON, R. T., 10, Anderson Street, Sloane Square, both in London. Jan. 21, 1933, No. 15077/32. [Class 38 (v).] Isolating-switches for use with overhead distribution lines each comprise a pair of switch contacts mounted on an insulator and insulated from one another, connections from one set of contacts to a main line and the other set of contacts to a branch line and a switch arm hinged to one set of contacts and having a limb adapted to co-operate with the other set of contacts for opening and closing the circuit and another limb which serves as a means for actuating the switch arm. As shown in Fig. 1, each switch comprises an insulator 14 around which is clamped the switch contacts, the fixed contact consisting of a contact jaw 15 and the movable contact of a blade 20 pivoted to a fixed clip 18a. The clips 18a are connected to branch lines 12 by jumpers 19 and the contact jaws 15 are connected to the main lines 6 by jumpers 17. Each switch blade is in the form of a bell crank, one limb of which acts as a blade contact member and the other limb as an actuating member, being pivotally connected to a clip 20a on a vertically-movable insulating operating rod 21 operable from the base of the pole 9 by a finger grip 21a. The rod 21 is provided with recesses 21b and a spring 24 so that it may be latched in its "on" or "off" positions. In an alternative arrangement, Fig. 5 (not shown), the insulators carrying the main and branch lines are disposed on opposite sides of the pole, the switch insulators being disposed intermediately.
