HEAT CONTROLLING MECHANISM Filed Dec. 4, 1930 f E? \x l K I i 0 i1 Fl'qfmEl INVENTOR HEnariE L 50022 ATTO RN EY Patented Nov. 17, 1931 i ENAnIn n. soon, or sAn an'ro'mo, TEXAS HEAT CONTROLLING MECHANISM Application filed December 4, 1930. Serial No. 500,129.
The present invention pertains to a novel heat controlling mechanism of a type particularlyradapted for use in garages wherein the constant passage of automobiles into and 5 out of the building renders the use of doors impossible.
The primary object of the present invention is to permit-the heating of an entrance lobby of a garage or similar building in a i manner to avoid loss of heat due to the latter passing out the entrance and to prevent excessive drafts of cold air entering the building through the entrance. A vane is pivoted in the entrance where it will be subject to pivotal movement as a result of pressure due to either ingoing or outgoing air currents, if the vane is moved inwardly it is a signal that more heat is required and if it is moved outwardly that isan indication that heat is being wasted and the supply can be decreased. The means for preventing the draft contemplates supplying heat through suitable ducts and providing a fan blower for supplying the heated air under pressure and the mo- 3 tor which operates the fan blower is of the variable speed type, the power thereto being controlled by a rheostat which is in turn cont-rolled by the movement of the vane.
With the above and other ends in view the invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure 1 is a fragmentary cross sectional view illustrating the main floor or entering lobby of a garage or similar building; 7 Fig. 2 is a fragmentary plan view of the heat-supplying duct, and
Fig. 3 is a detail View of a means for preventing rapid movement of the vane.
Like characters of reference are employed throughout to designate corresponding parts. The numeral 1 indicates the main floor of a garage or similar building, 2 the ceiling above said floor and 3 the entrance to the building. Pivotally suspended in the. entrance is a vane 4 which extends across a portion of the width of the entrance and leaves sufiicient clearance between the bottom of the vane and the floor beneath to permit downwardly to a slight degree as illustrated ing equipped with a pistonfhaving either a an automobile to pass under the vane. Coiled springs 5 are connected to each side of the vane and to rigid portions of the building to prevent undue pivotal movement of said vane.
A heat supplying duct 6 is connected to a 5: suitable heatingunit and is equipped with any conventional thermostat system to regulate the temperature of the air which is supplied into the building to heat the same. A fan blower 7 is driven by a variable speed elecno tric motor 8, and the wires 9, which supply the electricity to the motor are connected to a rheostat 10, the rheostat being connected by a link 11. to the vane El so that pivotal movement of the vane causes similar pivotal move- 55 'ment of the contact arm 12 in the rjheostat.
The outer end of the duct 6 is forked into a plurality of outlets 13 as illustrated in Fig. 2Land the forked ends are inclined or curved in Fig. 1 and the air which is blown through the duct is therefore directed in the direc- 1 tion of the entrance and against the vane l. In operation it will be assumed that a nun rent of air is blowing in throughthe entrance -75 3. As the air current strikes the vane l it causes the same to pivot and in so doing it causes a corresponding pivotal movement of the contact arm 12 in the rheostat which demotor 8 and the fan blower 7 so that the air supply isbc lecreased. at In Fig, 3there-is illustrated a mechanism "which may, if desired, be substituted in the place of the springs #53, this mechanism comprising a hydraulic cylinder v14 of the closed type with a rod 15 which is rigidly attached thereto pivotally secured to a rigid portion of the building. A stem 16 is pivotally con nected at one end to the vane 4, the opposite end projecting into the cylinder .14 and besingle opening or a plurality of openings formed therein. The cylinder is then filled with a liquid and it is apparent that in order that the vane may swing it must move the piston in the cylinder so therefore the piston may only move at a rate of speed which permits the liquid in the cylinder to flow through he small opening or openings in the piston. This device serves efiiciently to prevent the vane from swingingin the manner of a pendulum as a result of gusts of wind contacting with the same.
It will be readily understood from the foregoing that the present invention contemplates counter-acting incoming drafts by artificially creating an outgoing draft by provioing automatic means for regulating the velocity of the artificial draft. The pres ont device further serves as means for assisting in the heating of the building inasmuch as the artificial draft is created with heated air.
Although specific embodiments of the present invention have been illustrated and described it is to be understood that various changes may be made in the details of construction without departing from the spirit of the invention as set forth in the following claims, and such changes are contemplated.
What I claim is:
l. A device for controlling the supply of heat comprising a duct, means for forcing heated air through said duct, a pivoted vane located in a position where the heated air from said duct is projected against the same and where it will be subject to the outside air currents, and means connecting said vane and said means for forcing heat through said duct whereby movement of said vane causes a change in the heat supply.
2. A device of the character described comprising a vane supported in the entrance of a building where it is subject to in-flowing and out-flowing air currents, means for supplying heat to said building having an outlet adjacent said vane, and connection between said vane and said heat supplying means whereby variations in the position of said vane causes variations in the rate at which the heat is supplied.
8. A device of the character described comprising a vane supported in the entrance of a building where it is subject to in-flowing currents of cold air, a duct having its outlet end directed against said vane, means for forcing heat through said duct, and connection between said vane and said means whereby variations in the position of said vane causes variations in the rate at which the heat is supplied.
4. A device of the character described comprising avane supported in the entrance 'of a building where it is subject to in-fiowing and out-flowing air currents, means for'supplying heat to said building and directing it against said vane, and a rheostat connected to said vane and connected to said means whereby it controls the rate at which the heat is supplied.
5. A device of the character described comprising a vane supported in the entrance of a building Where it is subject to in-flowing currents of cold air, a duct having its outlet and directed against said vane, a fan blower for forcing heated air through said duct, a motor for driving said fan, and means connected to said vane for controlling the speed of said motor.
6'. A device of the character described comprising a vane supported in the entrance of a building where it is subject to iii-flowing currents of cold air, a duct having its outlet and directed against said vane, a fan blower for forcing heated air through said duct, an electric motorfor driving said fan, and a rheostat connected to said vane for controlling the electric supply to said motor whereby movement of said vane causes a variation in the speed of said motor.
