Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
192 words
A time variable thermostat for controlling a heater comprising, a temperature actuated switch connected to the heater for actuating the heater at a selected temperature having a movable contact and at least one fixed contact, said movable contact being moved out of engagement with said fixed contact when the selected temperature is reached to deactivate the heater and being movable into engagement with the fixed contact to activate the heater when a selected temperature has not been reached, a temperature selection arm connected to said movable contact for selecting the temperature at which said movable contact is out of engagement with said fixed contact, a clock motor having a shaft rotatable once in 24 hours associated with said temperature selection arm, a temperature selection disc connected to said shaft having a plurality of radially extending slots, at least one arm engagement pin slidably mounted within each of said slots and engageable with said temperature selection arm, each of said arm engagement pins being radially positionable along said associated slot which corresponds to a selected temperature, and biassing means biassing said temperature selection arm against at least one of said arm engagement pins.
Claim 2
Dependent Claim
192 words
A time variable thermostat for controlling a heater comprising, a temperature actuated switch connected to the heater for actuating the heater at a selected temperature having a movable contact and at least one fixed contact, said movable contact being moved out of engagement with said fixed contact when the selected temperature is reached to deactivate the heater and being movable into engagement with the fixed contact to activate the heater when a selected temperature has not been reached, a temperature selection arm connected to said movable contact for selecting the temperature at which said movable contact is out of engagement with said fixed contact, a clock motor having a shaft rotatable once in 24 hours associated with said temperature selection arm, a temperature selection disc connected to said shaft having a plurality of radially extending slots, at least one arm engagement pin slidably mounted within each of said slots and engageable with said temperature selection arm, each of said arm engagement pins being radially positionable along said associated slot which corresponds to a selected temperature, and biassing means biassing said temperature selection arm against at least one of said arm engagement pins.
Claim 3
Dependent Claim
43 words
A thermostat according to claim 1 wherein said temperature selection disc is in frictional engagement with said shaft to permit a relative rotation between said disc and said shaft and wherein said arm engagement pins are each in frictional contact with said disc.
Claim 4
Dependent Claim
47 words
A thermostat according to claim 1 further including a manual temperature selection slide spaced from said temperature selection disc having at least one friction slide engageable with said temperature selection arm when said temperature arm is disengaged from the arm engagement pins of said temperature selection disc.
Claim 5
Dependent Claim
54 words
A thermostat according to claim 1 further including a second fixed contact connected to a cooling unit and positioned on a side of said movable contact opposite from said former mentioned fixed contact, said movable contact further comprising a bimetal coil which is expandable and contractable with temperature variations to move said movable contact.
Claim 6
Dependent Claim
37 words
A thermostat according to claim 1 wherein each arm engagement pin includes an annular flexible sleeves portion, with annular sleeves portions of adjacent arm engagement pins in contact with each other for supporting said temperature selection arm.
Claim 7
Dependent Claim
15 words
A thermostat according to claim 1 including an annular temperature scale disposed on said disc.
Claim 8
Dependent Claim
21 words
A thermostat according to claim 1 including 24 circumferencially spaced slots each corresponding with an hour during a 24 hour period.
Claim 9
Dependent Claim
27 words
A thermostat according to claim 1 wherein said temperature selection disc includes 48 circumferencially spaced slots one for each half hour period during a 24 hour period.
Claim 10
Dependent Claim
42 words
A thermostat according to claim 1 further including a manual switch for manually engaging the heater, a cooler contact for connection to a cooling unit spaced from said former mentioned fixed contact, said manual switch also positionable to manually engaged the cooler.
