Abstract
490,897. Thermally-actuated valves. BRITISH BRASS FITTINGS, Ltd., and SPERRYN, G. N. Jan. 12, 1938, No. 994. [Class 135] In a thermostatically-controlled gas valve, the setting dial comprises two interengaging parts a, c of which inner part c is adjustably connected to the valve-setting spindle band capable of being operated to set the valve according to any of the range of heats indicated on it, and the outer part or dial head a is likewise adjustable according to the range of heats indicated on it, the two parts being so keyed that they can only be reassembled in the correct relation. For this purpose, the part c has two pairs of differently spaced lugs m, n for co-operation with lugs t, m of corresponding width on the part a. The spindle b has a collar d and a screwed end g which passes through a hole in the dial part c. A screw passes through one of the holes h into a tapped hole i in the collar d, the dial part c then being clamped by a nut x. The lugs m, n are formed on a shoulder j which is engaged by an externally calibrated flange s on the outer part or dial head a. The latter is secured to the part c by screws passing through holes r into tapped holes o in the calibrated face of the part c and may have a knurled edge or a rib formed by recessing its outer face, for manipulation purposes. The rotary movement is limited by a stop v co-operating with a fixed part. The spindle b may be secured to the valve in the manner described in Specification 359,144.
