Title: Improvements in or relating to mechanical interlocks for electrical switchgear
IPC: H01H33/46
Filed: 1932-07-06
Abstract: 408,274. Interlocking of switches; high-tension switches. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and BOOKER, F., c/o General Electric Co., Witton, Birmingham. July 6, 1932, No. 19105. [Class 38 (v).] Switch mechanism interlocking with lids.- Means for interlocking mechanically a plurality of parts of switchgear with a further part comprise the provision on each former part of a catch movable with the part and having an operative position in which it is arranged to engage the catch of another part to prevent or limit movement of both said parts. Movable with the further part is a stop adapted when the further part is in one position by engaging one of the catches to prevent disengagement of the catches, but when the further part is in another position or other positions to permit such disengagement. The general layout is shown in Fig. 1, and Fig. 4 shows the interlocks looking from the back in Fig. 1. The lid 2 of the enclosure 1 for the terminals, operating, and trip gear &c. of the main switch, and the lowerable tank 3 of the latter are provided with rods 9, 12, respectively, having interengaging shaped heads such that, when a stop 17 is in the position shown in Fig. 1 corresponding to the closed position of an isolating switch in casing 4, the rods cannot bo separated to allow removal of members 2, 3. The rod 9 fits closely in a guide 13 in a casing 8, and rod 12 is pivoted to 3 with freedom to rotate slightly in a guide 14 in casing 8. When 17 is moved to the left (Fig. 1) on opening the isolating switch, the rods 9, 12 can be separated and 2, 3 withdrawn, in which conditions one or other of two pivoted members 20, 21 is moved by springs so as to obstruct stop 17 and prevent closure of the isolating switch while the parts are exposed. Stop 17 is reciprocated in a guide 15 by means of linkwork operated from the isolating spindle 5, and carries a pin 28 whereby it is interlocked with the main switch spindle 6. The latter carries a sector 26 having an arcuate recess and a passage 27 at one face. In Fig. 1, the pin engages the sector and is prevented from moving to permit opening of the isolating switch while the main switch is closed. When the latter is open, Fig. 4, the pin can pass through passage 27 to allow opening of the isolating switch, and while the latter is open, the arcuate recess allows closure of the main switch for inspection purposes, but during inspection the outer wall of the recess prevents movement of 28, and hence of 17, to close the isolating switch. Preferably the main switch is latched closed, and the closing operation for inspection can proceed to just short of the latching position.

Filed: 1951-08-17
Abstract: 704,635. Dispensing liquids or gases. PILLIN, Ltd., J. B., and EARLY, K. C. Aug. 1, 1952 [Aug. 17, 1951], No. 19490/51. Class 116. [Also in Groups XXVIII and XXIX] Means for controlling the supply of fluid to a pipe with a valved nozzle by unwinding and automatically rewinding the pipe on a spring or weight loaded reel comprises a cam driven by the reel which causes a cam followed to be moved to control the supply. A cam 17 is mounted on a shaft 11 mounted in a boss in a block 3. The hub 1 of a reel rotates freely on a shaft 2 between spaced blocks one of which, 3, has a fluid inlet 5. A cam follower 25 mounted on a leaf spring 31 contacts the groove in the cam and when the cam has been rotated sufficiently the resulting vertical movement of the roller 25 operates a switch controlling the pump motor or operates valve controlling mechanism. The cam is rotated by a pin 7 on a plate 6 adjustably mounted on the hub 1, which pin engages a tooth on a wheel 10 secured to the shaft 11. The winding or unwinding of the pipe rotates the hub to cause the pin 7 to rotate the shaft 11 and the cam 17 thereon. The cam is held in position by a spring-urged detent lightly engaging a toothed wheel 15 on the shaft 11. The driving force of the pin 7 is sufficient to allow the wheel 15 to rotate through one tooth against the action of the detent. The pipe has a stop 27 to limit unwinding. The shape of the cam determines the length of pipe unwound before operating the switch or the like. The mechanism is set by securing the plate 6 to the hub so that the pin 7 is adjacent a tooth on the wheel 10 and the shaft 11 is rotated so that the roller is in the depression of the cam. On rewinding the pipe the switch is opened and the valve closed. The apparatus may be used for dispensing a gas.
