Abstract: 464,861. Thermal switches. PREMIER ELECTRIC HEATERS, Ltd., and NEWTON, A. E. Sept. 19, 1935, No. 25946. [Class 38 (v)] [Also in Group VI] A thermostatically controlled electric toaster is provided with a plurality of heat responsive elements, one of which is in use while the others are cooling. A toast carrier 21, 22, Fig. 2, is slidably mounted on a vertical rod 23, and is normally pressed upward by a spring 25, Fig. 5. The carrier is retained in its lower position by a catch 26, Fig. 7, engaging a horizontal lever 28 held in position by a spring 29. The other end 30 of the lever is actuated by the thermal element. A control member 31 of U-shape is pivoted on the heating chamber and is provided with an external handle 33. The part 32 of the control member engages the upper side of a lug 34, Fig. 7, to move the toast carrier downward till engaged by its catch 26. The carrier is provided with an integral bracket 36 adapted on its downward movement to engage an arm 20 actuating a switch 18 to supply current to the heater 14. To control the heat supplied, two pivoted strip metal arms 40, 41 carry bimetallic strips 43, 44. The free end of each strip engages the upper side of a catch plate 45 when the front end of its supporting arm is in its lowest position. During normal heating the bimetallic strips move out of engagement with the catch plate, and with their supporting arms are free to fall by gravity. The catch plate is pivoted on a bell-crank lever 47, Fig. 8, in such a manner that when the bimetallic strip is moved upward, the plate 45 moves aside into the dotted position and then returns to retain the strip on its upper face. The other arm of the lever 47 extends horizontally and engages one end of an adjusting lever 49, Fig. 4, the other end of which is bent, and slotted at 50 for connection to controlling mechanism adapted to vary the angular position of the lever, and thus of the bell-crank lever 47, with consequent variation in the amount of travel of the free ends of the bimetal strips necessary to disengage them from the plate 45. Each controller arm 40, 41 is provided with an abutment face 51 for engagement with the front end 30 of the lever 28 to pivot the latter out of engagement with the toast carrier catch when the bimetallic strips fall to their lower position, and so release the carrier to be moved upward by the spring 25. To permit the bimetallic strips to be used alternately and thus to enable them to cool between periods of use selector mechanism is used comprising an arm 52 carried by the starter handle, so constructed and mounted that successive actuations of the starter handle bring the strips into operative position alternately. The position of the adjusting lever 49 and thus the position of the catch plate 45 and the travel of the bimetallic strips, is controlled by an externally adjustable spindle 65 carrying an arm 66 which engages in the slot 50 in the adjusting lever, so that rotation of the spindle determines the heating period.
