Abstract

523,536. Pressure gauges. CAPSEY, L. W. C., and TOMEY & SONS, Ltd., J. Dec. 8, 1938, No. 35753. [Class 106 (ii)] In an instrument of the Bourden type, rigid stops hare provided which come into operation successively on the tube a towards the free end to reduce its effective measuring length. The stops are formed by radial screws h adjustable in the casing g which may be strengthened to receive them. In the case of a gauge arranged for measuring increase and decrease in pressure relative to the atmosphere, the tube is arranged to contact the first stud when the pointer is at zero.
