Abstract
464,149. Electromagnetic switches and interrupters. COLLE, V. G. VAN, and WARD & GOLDSTONE, Ltd. Nov. 14, 1935, No. 31512. [Class 38 (v)] [Also in Group XXXVIII] An electromagnetic device, such as a relay, comprises a core composed of two main limbs connected by an intermediate limb and an end transverse limb, a transformer having its primary and secondary windings surrounding the end transverse limb and a coil or coils wound on one or both of the main limbs respectively intermediate its end or their ends and in series with the secondary winding. The core comprises main limbs a<1>, a<2> connected by a transverse limb a<3> on which the primary and secondary windings e, f are wound. Between an intermediate limb a<4> and the ends of the main limbs a<1>, a<2> is mounted a coil g in series with the secondary f and the contacts i, i<1> which are in series with the contacts of a switch when the relay is operated on low voltage. A coil mounted on the limb a<1> may be in series with the coil g or be independent and is connected to a signal lamp or indicator. When the device is operated on high voltage, the limb a<4> is removed, and the operating contacts are disposed in series with the contacts e<1>, e<2> associated with the high-voltage supply. The frequency of the armature b is adjusted to that of the mains by means of a spring d and a contact c.
