MARCUS C. DOOLHTLE w v W ATTORNEYS United States Patent 2,983,215 DAMPER FOR RADIATORS Marcus C. Doolittle, La Crosse, Wis, assignor to The Trane Company, La Crone, Wis a corporation of Wisconsin Filed Aug. 13, 1957, Ser. No. 677,945
2 Claims. or. 98-40) This invention relates to a damper mechanism and particularly to an adjustable damper mechanism for adjustably controlling the rate of flow of air through a radiator.
It is an object of this invention to provide a damper mechanism which has simple inexpensive elements which are easily assembled on the unit.
It is another object of the invention to provide a damper mechanismwhich will releasably hold a damper in adjusted position.
Other objects and advantages of this invention will become apparent as the specification proceeds to describe the invention with reference to the accompanying drawings in which:
Figure 1 is a perspective view in section of a portion of the radiator.
Figure 2 is a transverse sectional view of a portion of the radiator.
Figure 3 is a partial sectional view taken on line 3-3 of Figure 2.
Figure 4 is an end view of the damper blade.
Figure 5 is an elevational front view of the damper blade.
Figure 6 is a transverse sectional view of the radiator.
Figure 7 is a perspective view showing the support mounting of the damper blade in thegusset.
Figure 8 is an exploded view of the hinge plate and the key plate.
Referring now to Figure 1, numeral 10 designates the casing of the radiator. The casing 10 has a plurality of louvers 12 which are struck downwardly from the surface of the casing to provide a plurality of air openings therein. As shown in Figure 6, a wall bracket 18 is secured to the wall by screws 17 or other suitable fastening means. The wall bracket 18 has an off-set flange 20 at its upper end to provide with the wall a recess for receiving a channel portion 14 ofthe casing 10. The wall bracket 18 has a downwardly extending V-shaped portion 22 at its lower end. These wall brackets 18 are mounted on the wall at spaced intervals. The casings 10 are mounted on the wall brackets by forcing the channel 14 and its gasket 16 downwardly into thespace between the wall and the off-set flange 20 of the wall bracket 18.
The lower end of the casing 10 has a clip 24 which is snapped onto the V-shaped portion 22 of-the wall bracket 18. An element hanger 26 is secured to: the wall bracket and the tube'28 is supported on the carriage- Inasmuch as the casinglO is spaced upwardly from the floor, air
may enter between the casing lti and the wall and rise through the heating element and passoutwardly between "ice gussets 32 are secured to the casings 10 as by spot weldmg.
A damper blade 34 has a rolled-over edge 36. The rolled-over edge 36 has portions 37 extending beyond the ends of the blade 34. These extensions 37 of the rolled-over edge 36 extend into holes 38 in the gussets 32 whereby the damper 34 is rotatably supported on the gussets 32.
A hinge plate 40 is secured opposite an opening 42 in casing 10. The hinge plate 40 has a prong 44 which extends through an opening 47 in the damper blade 34 whereby the damper blade 34 is pivotally supported by the hinge plate 40. The hinge plate 40 extends between the louvers 12 at each side of the opening 42 and is held in position by these louvers 12. A key plate 45 overlays the outer surface of the casing 10 and is secured to the hinge plate 40 by screws 46 which are in threaded engagement with the hinge plate 40. A wire screw 48 of tapered helical form has a shaft 50 extending through openings 52 and 54 in the hinge plate 40 and key plate 45 respectively. The shaft 50 has a flange 56 which engages hinge plate 40.
A washer 58 and a knob 60 are mounted on the shaft 59. The knob 60 is secured to the shaft 50 by a set screw 61. The damper blade 34 has a slot 62' through which the screw 48 extends. The damper blade 34 has a flange 64 which contacts with the casing 10 to prevent any substantial flow of air when the damper blade 34 is in closed position. Inspection of Figures 2 and 3 will show that a clockwise movement of the knob 60 will close the damper blade 34 and counter clockwise movement of the knob 60 will open the damper blade 34.
The screw 48 acts as a cam with respect to the damper blade 34 and the friction between these two parts is sufl'icient to prevent the weight of the damper blade from turning the screw 48. The screw 48 has a bent over end 65 which prevents the damper blade 34 from being disengaged from the screw 48.
Having thus described the preferred embodiment of my invention, I claim:
1. A housing for a radiator comprising a bracket adapted to be secured to a wall of an enclosure to be heated, said bracket being adapted to support a heating element, a casing secured to said bracket, said casing having a plurality of openings in its upper portion for the flow of air therethrough, gussets spacedly secured to said casing, a damper pivotally secured to said gussets and being pivotally movable to open or closed positions with respect to the openings in said casing, a plurality of louvers extending inwardlyv from said casing'and across the openings in said casing, a hinge plate secured to the inner side of said casing and having edges confined between louvers to position said hinge plate with respect to said casing, means on said hinge plate pivotally supporting damper, manual means secured to said helical wire member for turning said helical wire member to pivotally move said damper by the sliding engagement of said helical wire member with the edge of the slot in said damper.
2. A housing for a radiator comprising a bracket adapted to be secured to a wall of an enclosure to be heated, said bracket being adapted to support a heating element, a casing secured to said bracket, said casing having a plurality of openings in its upperfront portion for the flow of air therethrough, an elongated damper,
means adjacent the ends of said elongated damper for pivotally securing said elongated damper to said casing for pivotal movement to open or closed positions with respect'to the openings in said casing, a plurality of louthe'lou'vers 12. At'spaeed intervals along the radiator.
