The part of the current, a, supplying the magnet first passes through a small lamp and through two resistance coils so as to reduce the pressure. It then passes through the magnet, and is con- tinued on to the set-screw, b, which is so placed that when the thermoregulator comes in contact with it the current is com- plete.

The regulator consists of a strip of hard rubber and a. Thermo ret^ulai-or Fig. 27. Strip of brass riveted together. One end is fixed, while the other is free, and when it is heated it tends to bend toward the metal side, when it cools it bends toward the rubber. The brass strip is 15 inches long, \ inch thick, and \ inch wide; the rubber strip is \ inch thick, \ inch wide, and a little less than 15 inches long. In the diagram'the end is fixed at d and is free at h. When it is heated, the free end travels away from the set-screw at h; when it cools, it moves toward the set- screw. Rogers also recommends a regulator made of invar and.
