HEATING DEVICE.
Application led July 9, 1921.
To all whom t may concern:
Be it known that I, ALFRED E. DUT'roN, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State 6 of Ohio, have invented new and useful Improvements in Heating Devices, of which the following is a specification, the principle of the invention belng herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.
My invention relates to heating devices and particularly to heating devices of a portable nature, electrically operated and provided with means for producing a forced draft. The object of the invention is to rovide a device of the above described c aracter which is economical of construction and eicient in the performance of its function.
The said invention consists of means hereinafter fully described and particularly set forth in the claims. More specifically, my invention includes a heating device in which a multiplicity of chambers are provided, adjacent chambers communicating with each other through the medium of restricted openings, these chambers being preferably superposed, the uppermost chamber communicating by means of a duct, with the atmosphere, and the lowermost chamber communicating also with the atmosphere and associated with a fan for forcing atmospheric air throu h said chambers, baille plates being provided upon the interior of said chambers whereby a given amount of retardation of the air current is produced in each chamber; the latter being each furthermore provided with an electrically heated element for heating the air as it passes through or is retarded in said chambers. Other features of my invention .will be hereinafter more fully described.
The annexed drawing and the following descri tion set forth in detail certain means embo ying my invention, the disclosed means, however, constituting but one of the ivarious mechanical forms in which the principle of the invention may be employed.
In said annexed drawing:
Figure 1 represents a front elevation of` a portable heater embodying my invention. Figure 2 represents a side. elevatlon of same.
Figure 3 represents a section taken upon Serial N0. 483,4.
ure 1.
Figure 4 represents a section taken u on the planes indicated by lines IV--IV, igure 3.
lFigure 5 represents a diagram of the electrical connectlon.
The illustrated embodiment of my invention includes a housing 1 consisting of a front flat rectangular outer plate 2 of sheet metal and an inner insulating asbestos plate or lining 3; and a back sheet metal plate 4 which is curved as at 5 forming an enlargement 6 of a rear compartment 7 of the housing, which compartment will be hereinafter more specifically referred to.
'The ends of the housing 4consist of asbestos plates 8 and the to and bottom of rectangular plates 9 an 10 respectively. The interior of the space enclosed by this housing is divided by a vertical partition consisting ofthe plate or asbestos lining 12.
Forming a frame for these plates are two forward channel bars 13-13, Figure 4, a bottom horizontal angle bar 14, vertical rear angle bars 15-15; and the lates are suitably secured to the frame t us formed by means of screws and angle clips in any desired or well known manner. Suitable legs (ll are provided as shown as well as a han- The top of the com artment 7 communicates with the atmosp ere by means of an opening 16 in which is placed a suitable screen 17 for filtering the air which passes therethrough. The bottom of the compartment 7 is provided with an opening 18 through which rojects an extension 19 formed upon the ottom of a casing 20 of a heating member which is placed within the other compartment 21 formed bythe partition plate 12.
The extension 19 opens into the lower part of the compartment 7 and located within said extension is a fan 22 operated by a motor 23 which is located in the enlargement 6 of the compartment 7.
The casing 20 consists of two plates 24 and 25, each corrugated as shown, therear plate being formed with the extension 19. The number of corrugations are equal and they are similar in form so that when the plates are placed opposite each other as shown, chambers 26-26 are formed. Ad-
jacent chambers communicate with each as shown, and extends substantially throughout the entire width of the heater.
The uppermost chamber is provided with a baille late 29 which inclines downwardly and bac wardly and is located adjacent to the uppermost opening 27 A similar baille plate 1s placed near the other restrictedopening 27 excepting the lowermost one. Adjacent to the restricted openings 27 other than the topmost and lowermost openings, are upwardly and -forwardly(project1ng baffle plates 30. These latter exten throughout the width of the chambers 26. 'The ends of these chambers are formed by the end asbestos plates 8. The rear plate 25 is secured in place and to the adjacent plates by means of suitable screws and chps 1n any desired manner, its bottom resting upon the bottom plate 10. The front plate 24 1s also secured in a desired manner by means of suitable screws or clips and preferably has secured to it the front housing plates 2 and 3, so that when it is desired to have access to the interior of chambers 26 the reuired screws may be loosened and the said front plate 24 With the attached plates 2 and 3 removed.
The motor 23 is connected with a suitable source of electricity and a suitable switch 31, Figures 1 and 5, is provided for starting and stopping same.
Extending through each of the chambers 26 is a suitably supported insulated bar 32 which carries a resistance or heating wire 33. These wires are connected in parallel in the circuit as shown in Figure 5. The switch 31 is so arranged that these heating wires may be thrown into or out of the circuit in succession, as will be readily understood, so that for thepurposes of heat regulation one or more of the heating wires may be made operative.
In use, the above described device operates as follows:
The switch 31 is thrown to first close the motor circuit whereupon the'fan operates and draws air through the opening 16 downwardly through the compartment 7 through the extension 19 and upwardly through the chambers 26 from whence it finally emerges ina horizontal direction from the duct 28. The switch is then further closed, sending the current through the required heating wires which becoming incandescent heat the air passing'through said chambers. In so passing, however, this air comes into contact with the baffle plates which divert the current and retard its progress, thus creating a circulation whlch permits the heating wires to impart to the air, the required amount 0f heat. It will thus be seen that the heat of the heating elements may be efficiently applied and by regulating the speed of the motor and controlling the number of heating elements, the temperature of the emitted an' lmay be regulated. Furthermore, the above described construction is such, that ready access may be had to the heating elements and substantially the entire construction may be made of sheet metal, and may be readily and economically assembled.
What I claim is:
1. In a heating device, the combination of a housing having two compartments formed therein, the one compartment communicating at the top with the atmosphere and having an opening at the bottom; a casing in sald other compartment communicatin at the top with the atmosphere and at the ottom with said first-named compartment; electrical heating means in said casing; and means for forcing air from said first-named compartment through said casing.
