Filed: 1919-01-21
Abstract: 139,111. Jackson, W. J. Mellersh-, (Cutler-Hammer Co.). Jan. 21, 1919. Thermal switches; fluid actuation; contacts. - A thermostat has a temperature-controlled Bourdon tube, or similar actuator, which indirectly acts upon a movable contact positioned between two fixed contacts. The position of the fixed contacts and the effective position of the Bourdon tube may be adjusted whilst in service. The Bourdon tube 4, which is connected to a bulb 5 containing mercury or other expansible fluid positioned where it will be influenced by the temperature to be controlled, is fastened at the inner end of its spiral to a segmental plate 10, which may be adjusted by a screw 12 passing through a vertical slot in the base-plate, and by a screw 13 extending through a slot 11. The free end of the tube carries a pin 25 which lies between two L-shaped actuating-levers 21, 22 pivoted on studs 19, 20. Through spiral springs on the studs, these levers act in opposite directions upon the tail of a contact-arm 1 pivoted upon a post 15 and lying between the levers 21, 22. Movement of the studs 25 rotates one or other of the levers, which acts through its spring upon the contact-arm 1, closing the switch upon one of its contacts 2, 3. The springs prevent damage due to excessive expansion of the Bourdon tube. The fixed contacts 2, 3 of the switch are adjustable relatively to each other and to the neutral position of the movable contact 1. Each contact is. adjustably held in a post 33, 34 by a set-screw. The contact posts are fixed in a. carrier 31 which has a pointer 36 working over a scale 37 fixed to the base. The carrier engages a screw 30 in an horizontal slot 9 on the base, and the adjustment may be effected by means of a screw-driver through an opening 32 in the casing, which has a window. Specification 141,257, [Class 39 (iii).. Heating by electricity], is referred to.

Abstract: 947,397. Hydraulic pit props. GUTEHOFFNUNGSHUTTE STERKRADE A.G. June 9, 1960 [June 12, 1959], No. 20254/60. Heading E1E. [Also in Division F2] In an hydraulic pit prop comprising telescopic members 1, 2, 3 incorporating a relief valve adapted to maintain the resistance to lowering of the prop constant as disclosed in Specification 860,164, the telescopic members define a common pressure chamber having a single pressure duct. The pressure within the prop acts by way of a conduit 6, Fig. 1, on a spring- loaded valve 9, the force exerted by the spring being additionally opposed by pressure fluid fed through a check valve 13 and a branch duct 11 to an offset annular surface 12 of the valve 9 when the prop head 5 engages the member 3 to depress a plunger 14 and open the valve 13. In a modification, see Figs. 3, 3a and 4 (not shown), applicable to pit props incorporating four telescopic members, two valvecontrolled branch ducts are provided leading respectively to two offset annular surfaces in the valve 9. In a second modification, Fig. 5, the plunger 14 carries a ported abutment 20 acted on by opposed springs 21, 18, a ported conical member 17 blocking the connection 19 to the pressure chamber during the first lowering stage of the prop. The prop head may be provided with a series of relief valves connected in parallel and having different response pressures, see Fig. 6 (not shown).

Abstract: 766,702. Fluid-actuated valves. BLAKEBOROUGH & SONS, Ltd., J. July 12, 1955 [July 12, 1954], No. 20348/54. Class 135. In a by-pass valve comprising an axially movable sleeve 30 at the pump side of a main water supply valve 10, the inner end of the sleeve 30 being open to the pump supply, and a valve seat 42 connected with the outer end of the sleeve 30 being closable by a by-pass valve member 38, movement of the sleeve 30 to cause engagement and disengagement of the member 38 and seat 42 is controlled by the valve 10. The stem 14 of the valve 10 is connected by a fork-ended lever 28 to the sleeve 30 attached to an orifice block 34, designed to allow a given flow of water, connected to a housing 36 incorporating the seat 42 for the member 38 which is slidable in the housing 36; a stem 46 on the member 38 co-operates with an adjustable abutment 48. With the valve 10 closed water flows through the sleeve 30, housing 36 and an outlet 54; upon a demand for water arising on the outlet side of the valve 10 the latter is unseated whereupon axial movement of the stem 14 rocks the lever 28 and moves the sleeve 30, block 34 and housing 36 to the left, the member 38 remaining stationary due to differential water pressure on the opposite ends thereof, until the seat 42 engages the seat portion 40 of member 38 at which time the flow of water through the sleeve is terminated. As the valve 10 moves further off its seat the member 38 is moved together with the housing 36. As soon as flow ceases around the valve 10 and it returns to its seat the lever 28 moves the sleeve 30 to the right together with the housing 36, block 34 and valve member 38 during which movement the stem 46 engages the abutment 46 and its motion is stopped; the housing 36 continues to move and the seat 42 and seat portion 40 disengage to enable water to again flow through the sleeve 30.
