Abstract
Abstract A low wattage electrical resistance heating element is supported within a tubular housing, and an elongated flexible support band is adjustably connected to the housing and extends over a wallmounted thermostat for suspending the housing in vertically adjustable relation directly below the thermostat. An electrical power cord extends from the heating element through the housing to an electrical power supply, and energizing of the heating element produces a convection current of heated air upwardly through the housing. The heated air mixes with ambient air and flows into the thermostat to provide an air temperature higher than ambient air temperature so that the heating system is controlled in a manner to maintain an ambient air temperature lower than the setting of the thermostat.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
153 words
A heating device adapted for temporary use with a wallmounted thermostat connected to control a heating system to provide for a controlled reduction in the operation of the heating system below the effective operating control range of the thermostat, said device comprising an electrical heating element, a housing having an upper end portion and a lower end portion and defining an air flow passage extending between said end portiOns, means on said housing for supporting said heating element adjacent said passage to provide for a flow of air generally upwardly within said passage in response to heating of the air within said passage by said heating element, an electrical power supply cord connected to said heating element and extending from said housing for connection within an electrical power supply, and means for temporarily supporting said housing below the thermostat in a position where said passage directs the heated air upwardly into the thermostat.
Claim 2
Dependent Claim
153 words
A heating device adapted for temporary use with a wallmounted thermostat connected to control a heating system to provide for a controlled reduction in the operation of the heating system below the effective operating control range of the thermostat, said device comprising an electrical heating element, a housing having an upper end portion and a lower end portion and defining an air flow passage extending between said end portiOns, means on said housing for supporting said heating element adjacent said passage to provide for a flow of air generally upwardly within said passage in response to heating of the air within said passage by said heating element, an electrical power supply cord connected to said heating element and extending from said housing for connection within an electrical power supply, and means for temporarily supporting said housing below the thermostat in a position where said passage directs the heated air upwardly into the thermostat.
Claim 3
Dependent Claim
48 words
A heating device as defined in claim 1 wherein said means for temporarily supporting said housing includes means for adjusting the vertical position of said housing and said heating element relative to the thermostat to provide for precisely selecting the reduction in the operation of the heating system.
Claim 4
Dependent Claim
39 words
A heating device as defined in claim 1 wherein said means for temporarily supporting said housing, comprises a support member adapted to be attached to the thermostat and arranged to support said housing in suspended relation below the thermostat.
Claim 5
Dependent Claim
35 words
A heating device as defined in claim 3 wherein said support member comprises an elongated flexible band member adapted to extend over the thermostat and having at least one end portion connected to said housing.
Claim 6
Dependent Claim
37 words
A heating element as defined in claim 4 including means for adjustably connecting said end portion of said hanger member to said housing to provide for adjusting the vertical spaced relation between said housing and the thermostat.
Claim 7
Dependent Claim
24 words
A heating device as defined in claim 1 wherein said housing is tubular and is adapted to be supported with a generally vertical axis.
Claim 8
Dependent Claim
47 words
A heating device as defined in claim 6 including a generally flat panel positioned within said housing and supporting said heating element, and means secured to the upper and lower portions of said panel and cooperating with said tubular housing to define annular openings for said passage.
Claim 9
Dependent Claim
39 words
A heating device as defined in claim 1 wherein said housing defines a set of spaced holes, and said power supply cord extends through said holes to provide a strain resisting connection of said cord to the said housing.
Claim 10
Dependent Claim
31 words
A heating device as defined in claim 1 wherein said means for supporting said housing, comprises an adjustable member adapted to be attached to the thermostat and connected to said housing.
Claim 11
Dependent Claim
89 words
A heating device as defined in claim 1 wherein said housing comprises a cylindrical tube, said means supporting said housing including a flexible hanger member having opposite end portions connected to the upper end portion of said tube and adapted to extend over the thermostat, a panel positioned within said tube and supporting said heating element, and means projecting from the upper and lower portions of said panel and cooperating with said housing to define annular air flow passages within the upper and lower end portions of said tube.
Claim 12
Dependent Claim
92 words
In combination with wall-mounted thermostat connected to control a heating system, a heating device for providing a controlled reduction in the operation of the heating system below the effective operating control range of said thermostat, said device comprising an electrical heating element, means for temporarily supporting said heating element in spaced relation below said thermostat and for directing a flow of air heated by said element upwardly into said thermostat, an electrical power supply cord connected to said heating element, and means for adjusting the flow of heated air into said thermostat.
Claim 13
Dependent Claim
92 words
In combination with wall-mounted thermostat connected to control a heating system, a heating device for providing a controlled reduction in the operation of the heating system below the effective operating control range of said thermostat, said device comprising an electrical heating element, means for temporarily supporting said heating element in spaced relation below said thermostat and for directing a flow of air heated by said element upwardly into said thermostat, an electrical power supply cord connected to said heating element, and means for adjusting the flow of heated air into said thermostat.
