Abstract

311,682. Morse, S. Feb. 14, 1928. Thermostats.-In order that an electric heating- element of the type comprising a number of carbon blocks or the like may maintain its temperature approximately constant the blocks are mounted in or on a container or support having a co-efficient of expansion greater than that of the conducting blocks, so that when the temperature becomes excessive the pressure on the blocks is reduced and the resistance increased. A number of blocks 2 are arranged in a metal casing 1, having an insulating lining 3 and a screw 8 for regulating the pressure on the blocks, and current is supplied through leads 4, 5. Modifications are described in which the container is of spiral form, or is replaced by a spiral wall on the base plate; or in which the blocks are threaded on an insulated support which may be straight or spiral.
