Abstract

500,998. Two-part couplings. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Aug. 18, M37, No. 4859/38. Convention date, May 7, 1937. Divided out of 500,964. [Class 38 (i)] [Also in Group XXXVII] In a relay having an armature 17 adapted to be attracted upwards in a straight line path by an electromagnet 1, 1a, the movable contacts consist of flexible fingers 20 rigidly. supported near one end and operated upon intermediate their ends by an operating member 18 carried by the armature. The movable contact fingers 20 and the co-operating stationary contact fingers. 23, 24 are moulded in insulating blocks. In order that the relay may be readily replaced it is mounted on connectors c<SP>1</SP>, c<SP>2</SP> the ends of the contact fingers projecting outside the two sides of the support 22 and being inserted into slots 46, Fig. 4, where they engage conducting strips 43.
