Abstract: 1,129,927. Vacuum switches. GENERAL ELECTRIC CO. 12 April, 1966 [28 May, 1965], No. 15930/66. Heading H1N. A vacuum switch is provided with an auxiliary arcing electrode 30, to which the arc is transferred from the main contacts 21, 22, the arc on the electrode 30 being subjected to an axial magnetic field which reduces the arc voltage. About a stainless steel portion 17 of the evacuated envelope area pair of oppositely wound coils 42, 44 aligned respectively with one of the contacts 22, 21 and connected in series with the switch. The fields of these two coils interact to provide a strong radial field between contacts 21, 22 and between contact 22 and electrode 30. The radial field is transverse to the initial arc 28 and consequently tends to increase its arc voltage and the arc consequently moves rapidly on to electrode 30 to lie parallel with the field. The arc is caused to move circumferentially around the annular space 34 by means of spiral cuts (52) in contact. 22 and by making the connection 32 to electrode 30 at one point only adjacent to a break (50) in the electrode (Fig. 1a, not shown). In a modification, (Figs. 4-8, not shown), coils (78), (78a) inside the envelope support contacts (70, 72) which are provided with annular arc electrodes (90, 92) which cooperate with a fixed cylindrical electrode (88) to produce two series-connected arcs each subjected to an axial field. Electrode (88) and the contacts (70, 72) are slit longitudinally and the contacts are pierced to reduce eddy currents. Helical slots (139) in the edges of electrode (88) and spiral slots (142) in electrodes (90, 92) cause the arcs to be driven around the annular electrodes. Stainless steel vapour condensing shields are fitted.

Filed: 1923-06-26
Abstract: 208,113. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Chapin, A. J.). Dec. 7, 1922, [Convention date]. Compensating for wear.-A device for compensating for the wear of the shoes or band of a cam-operated brake comprises a member 4, rotatably mounted on the cam shaft 3, which carries a pawl 11 adapted to drive a ratchet wheel 8 keyed to the shaft, and a pawl 12, adjustably mounted on an eccentric stud 13, which also engages the ratchet wheel and is urged to the right by a spring 28 so that a threaded stop 16 normally engages the casing 6 surrounding the mechanism. The member 4 is secured to the fixed casing 6 by first engaging slots 18 with lugs 17 on the casing and then rotating the member 4, and felt washers 19, 20 serve to keep the casing free from dust. When the brake is applied, as, for example, by supplying compressed air to a diaphragm chamber 2, the rod 1 rotates the lever 4, and the pawl 11 drives the ratchet wheel 8 to rotate the shaft 3, while the pawl 12 moves to the left against its spring. On release of the brake the wheel 8 follows the return movement of the pawl 11, but when the wear of the shoes is sufficient to permit a tooth of the wheel to slip past the pawl 12 during application of the brake, then, on release, the pawl 12 limits the return of the wheel 8, and the pawl 11 slips past a tooth, so that subsequent applications are effected with diminished angular movement of the lever 4. The pawls 11. 12 are so mounted that thev mav be reversed when the ratchet wheel is reversed to permit the device to be used with a lever moving oppositely to the lever 4.
