Title: Control devices incorporating electric switches
IPC: G04C23/24
Filed: 1974-03-26
Abstract: 1505250 Time switches SMITHS INDUSTRIES Ltd 14 March 1975 [26 March 1974] 13376/74 Heading H1N A switch control arrangement particularly applicable to a time switch wherein tappets 14 on a dial 13 actuate a switch unit 15 by causing engagement and disengagement of a member 39 with a latch 41 operatively associated with contacts 43, 48, has a selector means 21 which can be retained in a plurality of positions in one of which it engages the latch 41 to prevent its latching with member 39 and thus inhibits actuation of contacts 43, 48 by the tappets, and in another position is disengaged from the latch 41 and allows contact operation by the tappets. As shown the selector 21 has four positions selected and retained by sliding a knob 23 to a respective position A, B, C or D. In position C (Fig. 11) an "off" tappet can depress spring-loaded member 39 to engage under latch 41 and thence lift the latter such that a nose 64 lifts contact 48 off contact 43; the top of latch 41 then lying in the path of an "on" tappet which disengages it from member 39 to allow contacts 48, 43 to close. In position A (Fig. 9, not shown) the tip 89 of member 21 engages part 71 of latch 41 under action of spring 90 and holds the latch clear of member 39, thus rendering it ineffective, and contacts 43, 48 are continuously closed. An additional position D is provided wherein the end 89 of lever 21 depresses the nose 63 to pivot the latch about 60 so that nose 64 holds contacts 48 permanently off contact 43 as in (Fig. 12, not shown). Additional position B causes the latch 41 to be held at a lower level such that member 39 has to be depressed a distance (w, Fig. 10, not shown) greater than distance z in order to engage latch 41, and this enables differentiation between tappets (14alpha, 14c) of differing length, thus providing one cycle per 24 hours whereas position C would provide two. A fixed contact may be provided above contact 48 to provide a change-over facility or to interchange the ON and OFF states.

Title: Improvements in control mechanism for selectively actuating remote devices such as valves
IPC: F16K31/44
Filed: 1938-05-09
Abstract: 508,620. Valves; actuating Bowden &c. mechanism. WHEATON, A. W. May 9, 1938, No. 13813. [Class 135] [Also in Group XXXI] In the mechanism for selectively actuating remote devices such as the emergency valves of a compartment tank truck described in Specification 504,289, locking means are provided which, when a selector rod has been coupled with its actuating means prevent the remaining rods from being coupled with their actuating means. As in Specification 504,289, a number of selector rods 1 ... 6 are arranged in pairs so as to be slidable through the walls of a housing 11 and are connected by swivels 28 to cables 27 connected to the emergency valves, the cables extending through conduits 26 connected to an end bracket 24. The actuating means for each pair of rods comprises as before a member 31 with upper and lower sleeves 32, 33 slidable along the rods, say 1, 2, against a spring 36. Each rod carries a coupling pin 37 slidable in a slot 34. The slot 34 with its actuator block 31 is moved clear of the pin 3<7> by the spring 36 in a certain position of a transverse rotatable locking rod 40. As before, each actuating member carries a roller 38 co-operable with a cam 39 on a transverse shaft 14. The latter carries a hand lever 15 with a latch lug 17 which co-operates with a similar lug 16 on a spring-biassed lever 19 which may be released manually or by the fusion of a link 20 in case of fire or from the front end of the truck by a cable 22. Each actuator block 31 carries a vertical pin 41, 42 or 43 which is urged against the looking rod 40 by one of the springs 36. The rod 40 has three circumferentially spaced flat bottomed recesses 44, 45, 46 corresponding to the pins 41, 42, 43 such that only one pin at once can engage the bottom of its recess. In this position, the pins 37 of, say, the rods 1, 2, are clear of their slots 34 and either rod may be rotated so that its pin moves behind the shoulder 35 ready for axial movement by the block 31. The other rods cannot be rotated as their coupling pins 37 are still locked in the slots 34. Each pair of rods has a slidable bolt 57, Fig. 9, arranged in the rear wall of the housing 11 and co-operable with flats 59 on the rods so that when one rod has been rotated to couple it to its actuating block, the other rod is locked against rotation. The rod 40 carries a finger piece 47 and a, dial 48 co-operable with a fixed pointer. To prevent movement of the rod 40 when a valve has been actuated, a cam 56 on the shaft 14 moves to allow a spring-biassed plunger 51 with a reduced end 52 to pass.below the rod 40 so that its thick part co-operates with one of three flats 50 on the rod which correspond to the recesses 44, 45, 46. Each of the knobs 29 on the respective selector rods has a pointer or arrow head 30.

Classes 38 (3) and 38 (5). A traction motor A is controlled by an electromagnetic relay controlling the motor contactor, the relay comprising a rocking member L biased in one direction by a spring G and in the reverse direction to close contacts LI, OL by a coil SC. The latter is energized on closing a push-button switch SPB, over contacts IC, which are closed when the contactor is open. Contact OC completes a maintaining circuit for coil SC and LI energizes the contactor coil CC. Opening of switch TPB allows the spring G to open the relay contacts and so open the contactor. Failure of the battery B has a similar effect, and overload in the main motor circuit energizes a coil TC to open the relay contacts even though coil SC is energized. The battery may be omitted and the control circuit energized from the motor circuit either wholly, Fig. 3, not shown, or partly, Fig. 4, not shown.
