Title: Improvements in or relating to electric relays or like electromagnetic apparatus
IPC: H01H50/60
Filed: 1920-11-16
Abstract: 175,083. Automatic Telephone Manufacturing Co., Ltd., and Roseby, P. N. Nov. 16, 1920. Relays.-Magnetic members adapted to move relatively to each other are so arranged that, on excitation, like poles are generated in adjacent ends which consequently tend to separate by repulsion. One of two soft-iron strips 1, 2, Fig. 2, is secured to the inside of a rectangular tube 3, carrying the exciting-winding 13. The other strip 2 is pivotally mounted so as to be capable of swinging downwards away from the strip 1, but is normally maintained in contact therewith bv means of a spring 10. When current passes through the winding 13, like poles are generated at both ends, and the free end 8 tends to move away by repulsion from the fixed end 9 to an extent that is determined by the strength of the exciting-current. The contact 16 may be so adjusted as to be closed by the end-member 14 for a predetermined current-strength. As shown in Fig. 3, the relay is shunted across a battery B and the member 14 is adjusted to lie normally midway between the points 15 and 16. When the battery has discharged to a given value one set of contacts is closed to ring an alarm bell A. Similarly when re-charging the battery, the other pair of contacts will indicate when the charging operation is complete.

Abstract: 211,603. Mitcheson, G. G., and Sumner, A. E. Dec. 1, 1922. Weather screens.-In side-curtain equipment of vehicles for use as part of an all-weather opening top or alone and comprising a spring-controlled cranked rod for supporting the curtain and adapted to co-operate with a stop when the door is opened, the stop is so constructed as to allow the spring controlling the cranked rod to be tensioned by rotation of the cranked rod in situ. The cranked rod comprises a part E, Fig. 1, for supporting the edge of the curtain D, a cranked part E<1>, and a lower part E<2> inserted in a socket F in the door B and surrounded by a torsion spring H with its lower bent end H<1> engaging a slot in the part E<2> and its upper end held in position by a cover plate J for the socket. The action of the spring H causes the part E of the rod to hold the edge of the curtain D resiliently against the adjacent curtain, but allows the hand of an occupant to be thrust out as a warning. A stop G on the door acts as an abutment for the cranked part E<1> of the rod, or a lug thereon, to prevent undue movement of the rod when the door is opened, and to allow the spring H to be wound up when the parts are in situ, the stop G is so constructed that it allows the part E<1> to pass over it in the opposite direction to that in which the spring H tends to move it. For this purpose, the stop may be a spring-pressed latch, Fig. 4, or be movable downwards against spring action, Fig. 5. In modifications, the cranked rod may be built up of two or more parts, the socket for the cranked rod may be independent metal socket and may be situated elsewhere, and other forms of spring may be used.
