摘要： 478,890. Arc-rupturing in switches. ELLISON, Ltd., G., and ANDERSON, J. July 29, 1936, No. 20966. [Class 38 (v)] In a circuit-breaker of the kind in which auxiliary contacts are separated after the main contacts and are associated with an electromagnetic arc-suppressing device in which the arc formed on breaking the circuit can be whirled and extinguished, the arcsuppressing device comprises an electromagnet e mounted between a pair of parallel iron plates t, two or more concentric metal rings v, w also mounted between the plates, the inner ring v being adapted to serve as, or to carry, the auxiliary fixed contact 4, and the outer ring or rings w being formed with an aperture 3 through which the auxiliary movable contact l can pass, and insulating plates u arranged between the inner faces of the iron plates t and the ends of the rings, so as to form with the latter a whirling chamber or chambers m in which the arcs set up between the auxiliary contacts are confined and extinguished. The winding of the electromagnet e is connected at one end to the fixed main contact b and at the other end to the fixed auxiliary contact 4. A wiper contact 6 associated with the movable contacts may be arranged to bear against the outer ring w until the arc is extinguished. In a modification, the electromagnet is mounted concentrically with the rings.

摘要： 461,368. Switchgear structures. ELLISON, Ltd., G., and STRATTON, H. T. Nov. 6, 1935, No. 30665. [Class 38 (v)] Electric switchgear comprises the combination of fixed main and earthing contacts contained in a case, a slidable carriage carrying complementary contacts and movable between the fixed main and earthing contacts, means actuated by the carriage for preventing opening of the lid of the case except when the complementary contacts are earthed, and a hand lever for actuating the carriage. The fixed main contacts c are housed in an oil-containing casing a having a hinged or removable lid b, and connected to bus bars. The main movable contacts are carried on a carriage g, which is horizontally slidable on guides h to separate contacts j from contacts c, and in the other extreme position to bring contacts k into engagement with earthing contacts l. The contacts j are connected by the flexible leads n and pivotally-connected links m to the terminal posts o having sockets p to receive testing plugs. A handle t on a shaft r is adapted to operate the carriage through the lever system s, z, q, and a cam w on the shaft r normally co-operates with a bell-crank y to limit the movement of the carriage to separation of c, j and their arcing-contacts 9, 10. In this position of the parts a further cam 6 has moved clear of the lever y, so permitting the latter to be moved to an inoperative position by a normally-padlocked push piece x, so allowing the handle t to be further rotated for moving the carriage to the earthing position. A flange 7 is apertured at 8 to allow the handle t to be padlocked in any of its three positions. To lock the lid b against removal in any but the earthing position of the carriage, a member 2 on the latter engages in a depending part 3' of the lid. Accidental return of the carriage when the lid is off is prevented by a spring plunger 4, 5 in a removable safety cover f for the contacts c, which plunger only allows movement of the carriage when the lid is replaced.

摘要： 431,156. Actuation of switches. ELLISON, Ltd., G., and ANDERSON, J., Wellhead Lane Works, Perry Barr, Birmingham. Jan. 26, 1934, No. 2716. [Class 38 (v)] Closing mechanism for a circuit-breaker comprises a solenoid a which, on energization, moves a lever m into a position in which it can be actuated by a cam 2 driven by a motor y, switch mechanism for controlling the motor, and means for actuating the said switch mechanism under the control of the solenoid. In the arrangement shown, the plunger b of the solenoid is connected by a link c to a lever d secured to a shaft e. The initial movement of the plunger rocks the shaft e and a lever 9 connected thereto. The upper end of the lever 9 engages a spring-controlled pawl 10 pivoted to a lever secured to a switch shaft 13, and the movement of the lever 9 initiates a switching movement which is completed by spring action and closes the circuit of the motor y and also a maintaining circuit for the solenoid a. On further movement of the plunger b, the lever d engages a lever f connected through levers i, j and l to the lower end of the lever m. This end of the lever carries a roller 22 guided between members 7 and 23 ; by the actuation of the lever f, the roller 22 is moved to the right to bring another roller 3 mounted on the middle portion of the lever m into engagement with the cam 2. The upper end of the lever m is connected by a link n through a spring o to one end of a two-part lever p, q, the part p of which is secured to a shaft r carrying a lever s which, when the cam 2 actuates the lever m, imparts the closing movement to the circuitbreaker. The part q is carried freely on the shaft v carrying the cam 2, the shaft v being driven by the motor through a worm x and worm wheel w. After the circuit-breaker has closed, a projection 21 on the shaft v engages a projection 20 on a lever 19 connected by a link 18 to the switch shaft 13 and moves the latter to the " off " position to reopen the circuit of the solenoid or motor.
