Abstract
194,360. Bailey, A. J., and Bailey, F. M. Dec. 3, 1921. Thermostats. - A fluid-operated valve controlled by a pilot valve operated by a thermostat comprises a casing 1 provided with a valve 2 carrying a piston 3. The cover 6 carries a rod 7, preferably of steel which has a small heat expansion, and the rod carries a fitting 16 which supports a rod 14 of large heat expansion. The lower end of the rod 14 acts as a valve to control the passage 10 admitting pressure fluid to the upper side of the piston 3, to control the main valve. The valve rod 14 may be adjusted vertically by means of worm gearing 17, 18, which may be provided with an indicator. A spring may be provided whereby any expansion of the rod 14 after the valve is closed is taken up by the spring. Alternatively, the rod 14 may be adjusted by a wedge 17, Fig. 3, which is forced between two portions of the rod by means of a screw 17<a>. The apparatus is adapted for controlling the supply of steam to a vat or drying chamber.
