Abstract

834,349. Collectors. BRENTFORD TRANSFORMERS Ltd. Sept. 17, 1958 [Oct. 7, 1957], No. 31316/57. Class 38 (1). A contact device for moving over a currentcarrying coil comprises an insulating carrier board 1 having rollers 2 tracking a rigid portion of the coil frame and contact assemblies 4 connected, through channel sections 5, pillars 6 fixed to board 1 and flexible leads 9, to rubbing contacts 11 urged by springs 12 against current carrier bar 3. The pillar 6 is rigidly fixed to board 1 at its lower end and is screw threaded at its upper end to receive screw 7 held captive in plate 8 which spans both the assemblies 4. Lead 9 has tag 10 held between screw 7 and plate 8. The contact assemblies comprise spring-loaded carbon or other rollers rolling on coil A as described in Specification 733,518.
