Abstract

275,729. Automatic Telephone Manufacturing Co., Ltd., and Adams, H. May 12, 1926. Contact-making relays, particularly of the polarized shunt-field type described in Specification 170,385, have their cores connected to the iron yoke 1, at the one end by the usual screws 4, 5 and at the other end by a member, Fig. 3, comprising a magnetic portion 10 with holes 8 which slip over the ends of the cores, and a non- magnetic portion 9 which is attached by screws 11 to the yoke. The cores are thus magnetically Joined to each other at each end and only when a current passes in the same direction through both electromagnets to the armature 12 attracted to a common pole piece 10.
