x 3 Claims. (01. 219-39) This invention relates to improvements in comsupplied to the heating element, a thermostat, bined fans and heaters and has for one of its obconventionally indicated at I4, may be introduced jects to provide a simple and practical device in between the coil of said heating element and which a heater and fan are assembled in a manswitch I i.

What is claimed is:

1. In combination, a fan and driving means therefor, a heating element in cooperative relation to said fan for producing a heated current of air, a casing enclosing said fan and heating element and having a front with an opening therein, a plurality of louvers pivotally disposed adjacent said front and in the path of said current of air, a connection between all of said louvers operable to simultaneously adjust the same about their pivots, asupporting plate for said louvers rotatable with respect to and engaging the front of said casing and provided thereon at intervals with instruck lugs which project into said opening to form supports in which said louvers are pivoted, a retaining ring extending about the front of said casing and engaging said supporting plate to frictionally retain the same in various rotative positions, and fasteners extending through said ring and into said front at points beyond the outer edge of said supporting plate and acting to releasably clamp said ring in cooperative relation to said plate.

2. In combination, a fan and driving means therefor, a heating element in cooperative relation to said fan for producing a heated current of air, acasing enclosing ,said fan andlieating,

element and having a front with an opening therein, and also having a foraminous wall at least partially encircling said driving means, fan and heating element, a plurality of louvers pivotally disposed adjacent said front and in the path of,said current of air, a connection between all of said louvers operable to simultaneously adjust the same about their pivots, a supporting plate for said louvers rotatable with respect to and engaging the front of said casing and provided thereon at intervals with instruck lugs which project into said opening to form supports in which said louvers are pivoted, a retaining ringv extending about the front of said casing and engaging said supporting plate to' frictionally retain the same in various rotative positions, and fasteners extending through said ring and into said front at points beyond the outer edge. of said supporting plate and acting to releasably clamp said ring in cooperative relation to said plate.
