Title: Improvements in pressure gauges
IPC: G01L7/16
Filed: 1944-05-15
Abstract: 589,176. Pressure gauges. EDWARDS & CO. (LONDON), Ltd., W., TILLS, J. W., LOVATT, J. B., and POTTS, F. C. May 15, 1944, Nos. 9234/44, 14037/44, 19307/44 and 4909/45. [Class 106 (ii)] In a McLeod type of gauge an overflow port at the fiducial position discharges excess liquid into a reservoir connected to the liquid of the balance pipe by way of a valve which is positively actuated by movement of the compressive means. A known volume of gas, occupying a chamber 23d, bores 25b; 25c and a gauge glass 28b, is compressed when a piston 21 descends, forcing mercury contained in a reservoir 24b into the chamber 23d, &c. and also through bores 21 g in the piston and up a balance pipe 34. When the piston is in its lowest position, the open end 34b of the balance pipe is level with the upper end 47a of the gauge glass, and excess mercury flows over the end 34b into a pipe 35 and thence into a bore 21d in the piston. Also, mercury which has seeped past the piston runs down a groove 21a* in its sloping upper end, and into the bore 21d communicating with the reservoir. When the piston returns to its upper position, mercury which has collected in the bore 21d returns to the reservoir through the bore 23i. In the embodiment shown, the piston is operated electromagnetically, a solenoid 64, slidable on pillars 55 receiving current through terminals 51, springs 74, and sliding bars 76 which follow the vertical movements of the solenoid. The solenoid and armature-also slidable on pillars 55-are each linked to a rocker 59. In addition, the armature is attached by a helical spring (not shown) to a rod 63, to the piston 21 by a ball-joint 63b. When the solenoid is energized the armature is drawn downwards, the helical spring is tensioned and urges the piston downwards. Gas is admitted to the gauge through bores 36b, 23o and 23n, and, when the piston is in the upper position, passes through the pipe 34, bore 21g and 23f into the chamber 23d. Two other embodiments are described in which the piston is operated mechanically, in one by a simple lever arrangement and, in the other, by an external hand wheel, operating a screw-and-nut device and moving the piston through a multiplying linkage, a flexible diaphragm being used as a seal. These embodiments are also described in Specification 589,226, which is referred to.
