Ora/71 W013i I flt 'WzQ Patented Apr. 11, 1950 v UNITED STATES PATENT OFFICE Trade-Wind Motorfans, Inc.,
Los Angeles,
Calif., a corporation of California I Application February 17, 1945, Serial No. 578,516
E This invention relates to heating and ventilating equipment and relates more particularly to means for obtaining a variable output of heated air in a room, or the like.
An object of this invention is to provide simple and effective equipment which includes means for regulating the output of heated air therefrom.
4 Claims. (Cl. 257-137) Another object of the invention is to provide equipment employed in combination with a typical radiator of the convector type for varying the quantity of room air circulating around said radiator to vary the heating output thereof.
Another object of this invention is to provide equipment for use in combinat on with a convector radiator'and having novel air circulating chambers, compartments or passages, and incorporatin means for variously utilizing said chambers, compartments or passages to obtain regulation of the warm air output of said radiator.
A further object of my invention is to provide equipment of the indicated type forming a compact and novel arrangement of elements and which is readily installable in connection with ajradiator.
A still further object of the invention is to provide novel operating and control means in equipment of the type indicated for readily obtaining regulation of the warm air output from said equipment.
The various objects and features of my invention will be fully understood from the following detailed description of a typical preferred form and application of the invention, throughout which description reference is made to the accompanying drawings, in which:
Fig. 1 is a front view of complete equipment incorporating the invention.
Fig. 2 is a vertical sectional view thereof to an enlarged scale, as taken in the line 2-2 of Fig. 1.
' Fig. 3 is a sectional view as on the line 3-3 of Fig. 2.
The disclosure that I am making in this application is intended to include such modifications which may fall within the broad concepts of my invention. The present disclosure, however, is based on the at present preferred embodiment of the invention which is illustrated in the drawing. The realization of the invention particularly incorporates a radiator l arranged in combination with a housing or cabinet II which is preferably compartmented for suitable housing and support of said radiator l0, air flow accelerating means 12, control means therefor l4, and means l5 operable by said control means for obtaining desired variation in the flow of air into and out of said cabinet.
The radiator Ill may be of conventional form and design. It may be of the cast iron fin type, or the metal fin type, it being only desired that it be a convector radiator.
The housing or cabinet ll may be made of material such as sheet metal and may comprise a front wall l6, end walls I! and I8, a top I9, 2. bottom 20, and a rear wall- 2|. As contemplated herein, the cabinet may be divided in compartments as by means of a vertical partition 22 extending between the top l9 and the bottom 20 and a horizontal partition 23 disposed between the side wall H and the vertical partition 22. In this manner the cabinet is divided into a relatively large radiator enclosing compartment 24 extending from front to back of the cabinet, for the full height thereof, and between the side wall l8 and the vertical partition 22; a compartment 25 in the upper part of the remaining portion of the cabinet and housing the air flow acceleratin means I2; and a compartment 26 in the lower part of said remaining portion of the cabinet and affording intermediate air passage means and housing the means l5. The compartment 25 i sealed off from the compartments'24 and 26 by the partitions 23 and 22, except as hereinafter described. However, communication between the compartments 24 and 26 is provided for by an opening 2! in the partition 22.
In accordance with the invention, the front wall It of the cabinet may be provided with louvred openings or grilles 28, 29 and 3D for the respective compartments 24, 25 and 26.
The flow accelerating means l2 may comprise a suitable electric motor 3| and a fan such as a centrifugal blower 32 driven thereby as by a shaft 33. The motor and blower may be supported by and be secured to the horizontal partition 23. The blower may be either single or duplex and, depending upon the quantity of air to be moved, two such blowers may be used, one on either side of the motor 3|. The blower or blowers 32 may have an air intake 34 drawing air from the compartment 25 and an outlet end 35 for discharging said air into the compartment 26.
The control means l4 may include a solenoid 36 which may be disposed in the compartment 25 and may besecured in fixed position as by a bracket 31 carried by a wall of the cabinet such as the front wall It. The solenoid 36 may include an electric coil 38 and a floating core such as a plunger 39 adapted to be raised when the solenoid is electrically energized and to fall by gravity, when released. In this invention it is desired to raise the plunger when the flow accelerating means are in operation. Accordingly, the means 14 also includes common electric wiring 40 which may be connected to a suitable source of electric current and further includes switch means 4| which maybe either manually or thermostatically controlled. It may be seen that with the switch 4| open, the motor 3| is at rest and the solenoid- 36 de-energized; with the switch closed the-motor is in operation to drive the blower 32 and the solenoid is energized to raise its plunger 39.
The means [5 which is operable by the controlmeans 54, may comprise means arranged in the compartment 26 and associated with the grille- 30 to open or shut off the flow of air through said grille. The means 15 may comprise a plurality of angularly disposed fixed vanes or louvres 42' extending between the walls- I! and 22 and adjacent to the grille 30, and a plurality of alternately disposed vanes or dampers 43, each pivoted as at 4 along the rear edges of the vanes 42. The vanes 43 are adapted to lie normally upon the. vanes 42', assuming this position by gravity and providin air passages 46 between the fixed vanes 42. When the solenoid 35 is energized to raise its plunger 39, means such as a chain 45, connected to the plunger and to the vanes 43 at points'between the pivots and free edges thereof, may serve to tilt or swing said vanes 43 to close the passages 46 between the fixed vanes 42. The lower vanes 43 are adapted to bear against the vanes 42' immediately above each vane 43 to effect such closure, and the uppermost vane 43 may bear against a lip 4! carried by the cabinet for similar closure purposes. It may be seen from Fig. 2 that the vanes 42 and 43, when arranged in passage closing position, effectively shut off any circulation of air through the grille 30 to the chamber 25.
When the equipment herein is to be used' for normal or low output of warm air to a room, or the like, the switch 4! is turned off or any control thereof will have turned it. oif. The: sole- 'noid being de-energized, the passages 46 are open and air may pass through the grille 30,. through said passages 46, into compartment 26. The air may then pass through opening 21 into the radiator compartment to be warmed by the radiator H3 and then pass through the grille 28 into the room. This circulation is normal and does not contemplate nor include any air circulation through grille 29.
When the equipment is to be used for accelerated or high output of warm air, the switch 4| is turned on or any control thereof may have turned it on to cause simultaneous energizing of both the motor 3| and the solenoid 36. The blower 32 will'now circulate air drawn thereby through the grille 28' into the compartment 25 and passed through the blower under pressure thereof into the compartment 26. Since energizing of: the solenoid has caused the vanes 43 to be lifted to close-the passages 45, the air in the compartment 26 may pass only through the opening 21 into the radiator compartment 24 to be warmed by theradiator it and then pass through the grille 2'3 into the room. The more rapid circulation of air; under these conditions, will provide a relatively' high output capacity of the equipment herein.
Having described only a typical preferred form and application: of my invention, I do not wish 4 to be limited or restricted to the specific details herein set forth, but wish to reserve to myself any variations or modifications that may appear to those skilled in the art and fall within the scope of the following claims:
