Abstract
Abstract ABSTRACT OF THE DISCLOSURE A control device is provided for controlling the temperature sensed by a thermostat in specific relation to the temperature control setting of the thermostat for thereby controlling work cycles of the system operatively connected to the thermostat. A low resistance heater element is mounted in a vented housing through which a convection current is generated when the heater element is actuated. A damper is movably mounted in the housing for adjusting the convection flow of warm air that outlets through the housing. The housing is mounted a predetermined distance from the sensor element of the thermostat and the thermostat is preset to a desired temperature setting. When the heater element in the device is not actuated, the device has no control over the operation of the thermostat. When the heater element is actuated, the extent of control of the device on the operation of the thermostat is regulable by adjusting the damper to control the output of warm air to the thermostat sensor. According to one mode of opera-tion of the device, the heater element may be operatively connected to a power supply cord of the type having a plug which is releasably connectable into an electrical outlet, for instance of the type conductively connected to a residential electrical system. According to another mode of operation of the device, the heater element may be operatively connected to a conventional commercially available timer of the type commonly employed in a household to automatically energize a light or appliance through a desired interval.

Total Claims: 11
Claim 1
Independent Claim
178 words
A discrete control device for controlling the temperature sensed by a thermostat in specific relation to the temperature control setting of the thermostat for thereby con-trolling work cycles of a heating or cooling system operatively connected to the thermostat, the control device comprising a housing having a plurality of air inlet vents and a corresponding plurality of air outlet vents, said housing defining an air passage between said corresponding pluralities of air vents for the flow of a convection current of warm air, a low resistance heater element mounted in said air passage of said housing for con-comitantly warming air in said air passage and thereby generating a draft of ambient air into said air passage to said air inlet vents which is warmed and expelled through said air outlet vents so as to provide a continuous convection flow of warm air upwardly through said housing, and damper means rotatably mounted adjacent said air outlet vents so as to permit regulation of the rate of flow of warm air in said air passage through said air outlet vents.
Claim 2
Dependent Claim
178 words
A discrete control device for controlling the temperature sensed by a thermostat in specific relation to the temperature control setting of the thermostat for thereby con-trolling work cycles of a heating or cooling system operatively connected to the thermostat, the control device comprising a housing having a plurality of air inlet vents and a corresponding plurality of air outlet vents, said housing defining an air passage between said corresponding pluralities of air vents for the flow of a convection current of warm air, a low resistance heater element mounted in said air passage of said housing for con-comitantly warming air in said air passage and thereby generating a draft of ambient air into said air passage to said air inlet vents which is warmed and expelled through said air outlet vents so as to provide a continuous convection flow of warm air upwardly through said housing, and damper means rotatably mounted adjacent said air outlet vents so as to permit regulation of the rate of flow of warm air in said air passage through said air outlet vents.
Claim 3
Dependent Claim
65 words
The control device as claimed in claim 1, said housing comprising a jacket member and a panel member, said panel member being releasably connectable to said jacket member so as to define a closure having oppositely arranged open ends, said air inlet vents being located in one of said open ends and said air outlet vents being located in the other of said open ends.
Claim 4
Dependent Claim
95 words
The control device as claimed in claim 2, said jacket including a panel member having corresponding interior and exterior planar major surfaces, and first and second spaced panel members having respective minor interior and exterior planar surfaces, said first and second panel members being connected to said panel member and said first and second panel members being arranged substantially normal to said major interior surface of said panel member, and securing means mounted on said interior surface of said panel member and between said first and second panel members for securing said heater element thereto.
Claim 5
Dependent Claim
87 words
The control device as claimed in claim 2, including a first plurality of air space members mounted in one of said open ends of said housing, and a corresponding second plurality of air space members mounted in the other open end of said housing, said respective first and second pluralities of air space members being extended between said jacket member and said panel member, said first and second pluralities of air space members defining said pluralities of air inlet vents and air outlet vents in said housing.
Claim 6
Dependent Claim
73 words
The control device as claimed in claim 1, including means mounted in said housing for restricting the rotation of said damper means between first and second positions, said first position of said damper means corresponding to the substantial closure of said plurality of air outlet vents in said housing, and said second position of said damper means corresponding to substantial access between said air passage and said air outlet vents in said housing.
Claim 7
Dependent Claim
76 words
The control device as claimed in claim 2, said damper means including a blade having a configuration corresponding to a horizontal section through said housing, said blade having a pair of opposite ends, a pair of spindles, one of said spindles being mounted in each of said ends of said blade, said blade being rotatably mounted in said housing on said respective spindles thereof, and means connected to each of said spindles for rotating said blade,
Claim 8
Dependent Claim
22 words
The control device as claimed in claim 1, including means operatively connected to said heater element for determining the on-off sequences thereof.
Claim 9
Dependent Claim

The control device as claimed in claim 1, including means carried on said housing for releasably connecting said housing to a surface in specific spaced relationship to a thermostat, without any attachment to the thermostat.
Claim 11
Dependent Claim
255 words
The control device as claimed in claim 1, said device having the capacity to produce a convection current flow of at least 2 to 14°F in an ambience having a prevailing temperature of 72°F. (11) A regulator for wall thermostats, comprising: a housing adapted to be affixed to a wall under a thermostat, the housing defining within it a passage for air, the passage having an inlet and an outlet with the inlet situated below the outlet, manually rotatable means by which said passage may be selectively restricted to a greater or lesser degree, and electrical means within the housing for heating the air within said passage thus promoting convective flow from the inlet to the outlet. (12) The regulator as claimed in claim 11, said manually rotatable means including a blade having a configuration corresponding to a horizontal section through said housing, said blade having a pair of opposite ends, said blade being rotatably mounted in said housing on said opposite ends, and means connected to at least one of said opposite ends for rotating said blade.
