Abstract

442,064. Thermostats. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland. June 13, 1935, No. 17097. Convention date, July 12, 1934. [Class 64 (ii)] [See also Group XXIX] A multiple thermostat device comprises an expansible tube 16, of for example brass, to the end of which are attached rods 19 of a material of a low coefficient of expansion, such as for example the metal known under the Registered Trade Mark " Invar," a further tube of brass 21 being attached to their free ends and in turn being attached to a central rod 11 which actuates a valve 6 through a multiplying lever mechanism 10, 9.
