Abstract

559,844. Pressure gauges. BRITISH THERMOSTAT CO., Ltd., and HURST, W. F. F. MARTIN-. May 1, 1941, No. 5673. [Class 106 (ii)] [Also in Groups XIII and XXXVII] A flexible metallic bellows a with end plates b, c is provided with a sleeve h and coaxial rod i which inter-engage through an anti-friction device comprising a cage k carrying steel balls l, whereby distortion of the bellows in expanding or contracting is prevented. Springs m, n are provided to retain the cage k in central position and prevent its displacement during disengagement of the guides h, i. A plug e is provided, to permit evacuation of the bellows, which is then sealed at g, or, if desired to be responsive to pressure changes, the aperture g is left open and the plug e threaded for attachment of a pipe. An alternative is described in which the cage k is provided with a toothed pinion engaging both the rod i and sleeve h to maintain it in central position.
