AIR-HEATING ATTACHMENT.

Specification of Letters Patent. Patented Aug, 10, 1920,

Application'filed December 6, 1919. Serial No. 342,966.

To all whom it may concern:

Be it known that I, GEORGE D. KENNEDY, a citizen of the United States, residing at Jefferson City, in the county of Cole and State of Missouri, have invented certain new and useful Improvements in Air-Heating Attachments, of which the following is a specifiaation, reference being had to the accompanying drawings.

This invention relates to certain'improvements in air heating attachments, and it is an object of the invention to provide an attachment of this general character having novel and improved means whereby it may be employed with convenience and facility for heating rooms or the like, and which is adapted to be employed in connection with heating units such as gas lights, oil burners, or the like. i

It is also an object of the invention to provide an attachment of this generalchan acter which is adapted to be positioned above and in closeproximity to a flame, and which device includes a coil leading from a source of relatively cold air supply.

'1 he invention consists in the details of construction and in the combination and arrangement of the several parts of my improved air heating attachment whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings:

Figure 1 is a view partly in elevation and partly in section illustrating an air heating attachment constructed in accordance with an embodiment of my invention and employed in connection with an oil stove;

Fig. 2 is a view in bottom plan with a portion broken away of my improved attachment as herein disclosed; and

Fig. 3 is a view in elevation illustrating an attachment constructed in accordance with an embodiment of my invention and employed in connection with a gas burner.

As is particularly illustrated in Fig. 1 of the accompanying drawings, C denotes a casing oi? a type generally employed in an oil stove and positioned within said container is an oil receptacle or well It with which co acts in a conventional manner a burner 13. Disposed through the receptacle or well It and the burner B is a pipe I open at its lower end so that the cold air which is generally found adjacent the floor of a room may pass upwardly therethrough. This relatively cold air as it passes upwardly through the pipe P and through the receptacle R serves to maintain the oil within the receptacle or well R in a cool state.

The pipe P terminates a predetermined distance above the burner B or more particularlythe spreader S coacting with said burner and detachably coupled with the upper end portion of said pipe, as indicated at is the end portion of a pipe 2 which is continued by the coil 3 secured to and underlying the plate 4. l

The plate 4; as herein disclosed is substantially concavo-convex in form, and is of a size to permit its ready insertion within the casing C. The coil 3 has its inner end terminating at substantially the axial. center of the plate 4, and communicates with the opening 5 disposed through said plate so that the air passing through the pipe 2 and the coil 3 will be discharged through said opening 5 above the plate 4:.

Carried by the plate 4 and overlying the opening 5 at a desired distance thereabove is a spreader plate 6 which serves to deflect the air discharged through the opening 5 in such a manner as to materially increase the heating action of said air.

By having the plate 4.- and the coil 3 carried thereby positioned above the burner B it will be at once self-evident that the air passing through the coil 8 will be heated to a comparatively high temperature, so that the heat from the burner which otherwise would be substantially wasted is employed with advantage, as the heating qualifications of the stove will be materially increased.

I also find it of advantage to provide the plate 4 intermediate the convolutions of the coil 3 with the openings 6 which assures a proper draft for the flame and provides for the necessary air to support combustion.

In the embodiment of my invention as illustrated in Fig. 3 the attachment A is substantially the same construction as has been set forth relative to my attachment as particularly illustrated in Figs. 1 and 2,

except the pipe 2 extends laterally of the plate 4 and is provided with a downwardly directed extension 7 terminating in an end portion 8 occupying a plane substantially parallel to the plane of the pipe 2. The portion 8 is adapted to be secured to a lamp fixture F by the medium of the clamps 9 or the like. As is particularly illustrated in Fig. 3, the outer or free end of the portion 8 has coupled thereto a flexible tube T which may extend exterior of the building, so that the air drawn through the attachment'may be of a temperature equal to the temperature of the air on the outside, although if preferred the tubing T may be carried to a suitable point in close proximity to the floor.

The extension 7 as herein disclosed comprises a swivel joint 10 so that if desired, the attachment A may be swung into an inoperative position.

From the foregoing description, it is thought to be obvious that an air heating attachment constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification Without departing from theprinciples and spirit thereof, and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except ashereinafter claimed.

What is claimed is:

1. An air heating device comprising a plate adapted to be supported adjacent a heating medium and provided with an opening, a coil carried by the face of the plate opposed to the heating medium, the inner end of the coil being in communicationwith the opening in the plate, the opposite end of the coil being in communication with the atmosphere, said plate being provided with additional'openings arranged between the convolutions of the, coil.

2. An air heating device comprising a plate adapted to be supported adjacent a heating medium and provided with an opening, a conduit carried by the face of the plate opposed to the heating medium and discharging through the opening in the plate, said conduit being in communication with the atmosphere, and a spreader overlying the face of theplate remote from the heating medium, said spreader also overlying the opening.

3. An air heating device comprising a plate adapted to be supported adjacent a heating medium and provided with an open.- ing, a conduitcarried by the face of the plate opposed to the heating medium and discharging through the opening in the plate, said conduit beingv in communication with the atmosphere, and a spreader overlying the face of the plate remote from the heating medium, said spreader also overlying the opening,'said spreader being carried by the plate.

In testimonywhereof I hereunto my signature in the presence of two witnesses. GEORGE DENISKENNEDY. Witnesses:

M. B. HART, C. D. Srouen.
