18,945. Segesvßry, E. Sept. 9. Thermostats.-An expansible liquid such as ether is contained in a closed chamber, Fig. 2, exposed to the temperature to be regulated. On expansion of the ether, a small quantity is forced through a pipe a into an expansible capsule d, Fig. 1, heated by the steam or other heating-medium employed, where it vaporizes and presses out a diaphragm b, thus closing a valve e controlling the supply of the heating-medium. A piston may replace the diaphragm b. The expansible and volatilizable fluids may be different, a diaphragm separating them ; the liquid forced into the chamber d must have a boiling-point lower than the temperature of the heating-medium. The chamber, Fig. 2, containing the expansive liquid, has one side formed by a diaphragm h, which is adjusted for any temperature by a screw k and spring i.
