Sept. 8, 1931.' 0. ANDREW STOVEPIPE HEATER Filed Oct. 8. 1927 Oman flndrew W firm 14101 48 Patented Sept. 8, 1931 UNITED STATES OREN ANDREW, OF WATKINS, NEW YORK STOVEPIPE HEATER Application filed October 8, 1927. Serial No. 224,941.

This invention aims to provide novel means whereby cold air may be drawn from a point adjacent to the floor of a room, and be heated, the construction being such that the heating {if is brought about through the instrumentality of the products of combustion passing up a stove pipe, and no additional expenditure of fuel being necessary, in order to heat the air as aforesaid.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

WVith the above and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings Figure 1 shows in longitudinal section, a device constructed in accordance with the invention, parts being broken away;

Figure 2 is a longitudinal section taken in a plane at right angles to the cutting plane in Figure 1;

Figure 3 is a horizontal section; and

Figure 4 is a sectional elevation showing the means whereby rotation is imparted to the damper.

Figure 5 is a central vertical sectional view of a modified form of the invention.

In the accompanying drawings, the numeral 1 indicates a barrel-shaped body, adapted to be connected at its ends with a stove pipe 2 or other member through which the products of combustion pass, from a stove or furnace. Located within the body 1 and extended transversely of the same, is a flue 3 which, preferably, is of greatest diameter from a point intermediate its ends, the flue 3 tapering to its ends 4 and 5, the ends 4 and 5 being of cylindrical form, and being mounted to turn in the body 1. In order that the flue 3 may be held against moving endwise, as it turns, the ends 4 and 5 of the flue are supplied with flanges 6 which engage the inner surface of the body 1 as clearly shown in the drawings. The body 1 preferably is made of separable parts, as indicated at 7 in Figure 2, the parts 7 being joined together in any suitl5 able way, as shown at 8. The body 1 is made in separable parts, as aforesaid, so that the flue 3 may be mounted in place readily within the body 1, as shown in Figure 1 of the drawings. A damper 9 is connected to the flue 3 and is of such size as to control .the' I passage through the body 1.

The numeral 10 marks a vertical conduit of such length as to extend down to a point adjacent to the floor of the room in which, the device is mounted. The conduit 10 has a '7 horizontal end 11 which is received in the end 5 of the flue 3. There is a transverse slot 12 in the end 11 of the conduit. :On the end 5 of the flue 3 is mounted an operating mem-; ber 14 of any desired sort, such as a wheel 14. A securing element 15 connects the wheel 14 with the end 5 of the flue 3. The securing element 15 extends into the slot 12 that is formed in the end 11 of the conduit 10. I

In practical operation, cold air taken from a point near to the floor, moves upwardly through the conduit 10 and is heated in the flue 3, the heated air passing out through the end i of thefiue and creating an up-draft of, 30 cold air through the conduit 10. The products of combustion from a stove, furnace, fire-place or the like, pass upwardly through the pipe 2 and the body 1, and, consequently, the air that passes through the flue 3 is heat- 35 ed without any additional expenditure of fuel. The draft through the body 1 may be regulated by rotating the flue 3, so that the damper 9 stands either open or closed with regard to the body 1. The slot 12 is 1115390 length. When the securing element or screw 15 is at one end of the slot 12, the damper 9 is closed, and when the screw or securing element is at the opposite end of the slot 12, the damper is open. The operator simply turns; the hand wheel 14 as far as possible, in one direction or in an opposite direction, and he is assured that the damper is either open or closed, depending upon the position he may. wish it to be. T

The securing element 15 has a number of functions. First, it connects the wheel 1 1 to the flue 3, so that when the wheel is turned, the flue will be turned also, to open or close the damper 9. Second, because the securing element 15 is received in the slot 12, the end 11 of: the conduit 10 is held intheend 5 of the flue 3. Third, because the-securing element or screw 15 engages the part llatthe ends of the slot 12, the operator can determine definitely the position of the damperS, as hereinbefore explained.

In Figure 5 of the drawings, parts hereinbefore described have been designated by numerals previously used, with the suflix a. In this-form of. the invention, the damper: 9 and attendant parts are omitted, anda damper 25 is placed in the pipe 2a, above the flue 3a, the numeral 26 designating any. suitable means for manipulating the damper.

hat is claimed is 1'. In a device of'the class described, abody of greatest diameter intermediate its ends and:tapered toward its-ends, and a flue eX- tended throughthe bodytransversely and located at the place where the body is of greatest diameter, the flue being of greatest diameter-at a point intermediate its ends and at the-longitudinal axis of the-body, the flue tapering toward its ends within the body.

2. In a device of the classdescribed, a'body of greatest diameter inter-mediate its ends and taperedtoward itsends, and a flue extended through the body transversely and located at the place where the bodyis of greatest diameter, the flue being of greatest diameter at apoint intermediate its ends and tapering toward its ends within'the body, the flue being provided with circumferential flanges which-cooperate with oppositely disposed portions of the body.

In testimony that I claim the foregoing as my own, I- have hereto aifixed'my signature.

ORE'N'. ANDREW.
