Abstract
A cut-back thermostat construction having a frame carrying a timer and a thermostat arrangement. A movable actuator is carried by the frame and is operatively associated with the thermostat arrangement to cut back the temperature setting thereof when the actuator is moved from a first position thereof to a second position thereof, the timer having a cut-back member for engaging and moving the actuator from the first position thereof to the second position thereof when a predetermined time is reached by the timer whereby the temperature setting of the thermostat arrangement is cut back at the predetermined time.
Claims17
A cut-back thermostat construction having a frame means, a timer means carried by said frame means, a thermostat arrangement carried by said frame means, movable actuator means carried by said frame means and being operatively associated with said thermostat arrangement to cut back the temperature setting thereof when said actuator means is moved from a first position thereof to a second position thereof, said timer means having cut-back means for engaging and moving said actuator means from said first position thereof to said second position thereof when a predetermined time is reached by said timer means whereby the temperature setting of said thermostat arrangement is cut back at said predetermined time, said thermostat arrangement comprising an electrical switch means carried by said frame means and a temperature responsive switch operator movably carried by said frame means for operating said switch means in accordance with sensed temperature, said actuator means cutting back said temperature setting of said thermostat arrangement by adjusting said temmperature responsive switch operator relative to said switch means, and an adjustable cam being carried by said frame means and being operatively associated with said temperature responsive switch operator to set the same to provide said temperature setting of said thermostat arrangement, said switch operator having a cam follower operatively associated with said cam for following the adjustment thereof, said actuator means including a movable wedge member disposed between and in engagement with said cam follower and said cam.
A cut-back thermostat construction having a frame means, a timer means carried by said frame means, a thermostat arrangement carried by said frame means, and movable actuator means carried by said frame means and being operatively associated with said thermostat arrangement to cut back the temperature setting thereof when said actuator means is moved from a first position thereof to a second position thereof, said timer means having cut-back means for engaging and moving said actuator means from said first position thereof to said second position thereof when a predetermined time is reached by said timer means whereby the temperatuure setting of said thermostat arrangement is cut back at said predetermined time, said thermostat arrangement comprising a plate movably carried by said frame means and a magnet operated electrical switch unit secured to said plate, said thermostat arrangement further comprising a manually adjustable temperature responsive permanent magnet carried by said frame means for operating said switch unit in accordance with sensed temperature, said actuator means being operatively associated with said plate to move the same relative to said permanent magnet to cut back the temperature setting of said thermostat arrangement when said actuator means is moved from said first position thereof to said second position thereof.
