SPECIFICATION forming part of Letters Patent No. 438,297, dated October 14, 1890.

Application lecl December 31, 1889- Serial No. 335,496. (No model.)

T a/ZZ whom t may concern/ Be it known that I, GARRETT G. BURTON, of the village of Trenton, in the county of Hitchcock and State of Nebraska, have invented certain new and useful Improvements in Heating-Drums and Dampers; and I do hereby declare that the following is a full, clear, and

exact description thereof, reference being had air to pass into the drum A.

to the accompanying drawings, and to the letters of reference marked thereon, which form a partof this specification.

This invention relates to improvements in heating or radiating drums and dampers for stove-pipes; and the same consists in the several novel features of construction herein illustrated, described, and more particularly pointed out inthe appended claims.

In the drawings, Figure 1 represents a front sectional elevation of my invention, and Fig. 2 a transverse sectional view of the same, the latter being taken on the line 2 2 of Fig. 1. Fig. 3 is a view similar to Fig. l, showing the movable parts in a changed position. Fig. 4 is a sectional View, the parts being positioned as in Fig. 3, taken on the line 4 et of Fig. 3.

In the drawings, A is the outer shell of the drum or radiator, the same preferably being of oval form in side or front view.

a is a hollow sleeve adapt-ed to iit into or over a section of a stove-pipe, thus permitting the products of combustion, smoke, and heated a is a similar hollow sleeve diametrically opposite to the sleeve a, affording an exit for the cooled smoke or other products of combustion after having passed through the drum, as will be hereinafter explained.

CL2 is the back wall or face of the drum A, and as is the front wall or face.

Secured within the drum A by any suitable means are the diaphragms or partitions a4, located parallel to each other, as shown in Figs. 1 and 3, and forming between them the passage-way a5. The lower rear ends of the walls a4 extend downwardly almost to the oval end a6 of the drum, while the top portions of the walls a4 extend from the back wall a2 to the front wall Co2, thus leaving triangular-shaped passages a7, through which the heated air, smoke, and products of combustion may pass from the sleeve a when the passage a5 is closed by the inclined damper B.

Pivoted at b to the walls a4 is a movable deliecting-damper B, which, when in the inclined position illustrated in Figs. 1 and 2, completely closes the passage-way a5 between said walls a4 and forms the upper inclined wall of the passageway a2,'as will be readily understood.

B is a handle secured at one end of a rod b', which latter is passed through a suitable -opening in the rear wall a2 of the drum, and

is connected at its forward end b2 to the dam-per B, as clearly shown in Figs'. 2 and 4f.y rlhe defiecting-damper B is opened by pulling the handle B, as shown in Fig. et.

Extending into the top of the drum A are two concavo-convex walls C, constituting, as it were, a continuation of the pipe a. These Walls lit closely within the front and back Walls CL2 a3 of the drum, thereby forming an air-passage c.

Centrally with the space c is a shaft C', revolubly mounted in the front and rear walls a2 a2 of the drum, and extending outwardly at the rear to form a handle C2, by means of which the shaft and the parts carried thereon may be rotated.

c is an elongated slot in the rear wall a2, through which the shaft C passes, by which slot a vertical movement may be given to one end of the shaft C when desired, as will be hereinafter explained.

A revoluble damper is mounted on the said shaft C', which damper consists of the two end plates D, mounted at right angles to the shaft C', and a plurality of plates D D2 supported on and mounted between the two end plates D. The end plates D are provided with suitable long and short openings d. The horizontal plates D are of the same width as the vert-ical end plates D, and are provided with central openings d. The lower horizontal plate D2 is of less width than the end plate D, and is narrower than the spaces between the two lower ends c2 of the walls C, thus forming a passage-way c2 between either side of said plate D2 and the ends c2 of said walls. The central plate D2 is of the same width as the end plates D, thus forming on either side thereof a passage-way c4 between the ends of said plate D2 and the inner walls ICO of the plate C. The upper horizontalV plate D2 is less in width than the platesD and is greater in widthv than the lower plate D2. Spaces or passages c5 thus are'formed between the edges of said upper plate D2 and the upper ends or portion of the walls C, said spaces c5 being less in size than the spaces c2'.

By the construction shown in Figs. l and 2, as just described, it will be observed that the smoke and other products of combustion may pass from the drum A out through the sleeve a by passing in t-he circuitous direction indicated by the arrows through the openings or passage-ways c2 d c4 d c5, having, however, been turned and deflected en route by the several plates D D2.

Extending from the bottom plate D2 toward the top plate D2 and inclined from the rear wall a2 toward the front wall a3 is a deflectling-plate E, secured to the several plates D2 D', as clearly shown in Fig. 2. It will also be observed that the deflecting-damper B is inclined from the rear wall a2 toward the front wall a3. The object of thus inclining both the deilecting-damper B and the deflectingplate E toward the wall a2 is to cause the smoke and other heated products of combustion to impinge against said wall a3, it being understood that the wall a2 is the rear wall of the drum and will uniformlybe positioned against or close to the wall of the comparti ment to be heated. 4It is therefore desirable that if one part of the drum A be warmer than another and capable of throwing off a greater amount of heat than the other it should be the front wall a2. For this reason the currents of heated air are directed by the deflecting-damper B and the defiecting-plate E toward this front wall a3.

The upper ends of the walls a4 are flared outwardly, as clearly shown in Figs. l and 3, passing outside of the lower ends of the walls C, thus forming a passage-way a8 between the upper portion of said walls a4 and said wall C. The outwardly-extending upper portions of the walls a4 also serve to deflect the heated currents toward the outer portion of the drum A, as will be readilyT understood. v

The parts being positioned as shown in Figs. 1 and 2, the operation is as follows: The heated air and products of combustion pass into the drum A through the sleeve a, and impinging against the under side or face of the inclined deiiecting-damper B are directed against the wall a3 of thedrum. The current is then divided and directed through the passage-way a7 upwardly toward the top of the walls a, then through the passage-way a2 into the revoluble damper by means of the passage-ways c3 d c4 d c5, and thence into the sleeve a. In makingthis'circuitous passage through the revoluble damper the products of combustion are directed by the deflectingplate E toward the front of the heating-drum for the purpose above explained. It will thus be seen that a passage is formed for the heated air through the drum A, yet said passage is a circuitous one and of such construction as to retain the heated air and products of combustion in the drum until the maximum amount of heat in said airV is imparted to said heating-drum.

When it is desirable to give the air and smoke free passage through the drum-as, for example, when the lire in the furnace or stove is being built or replenished-the deflectingdamper B and the revoluble damper may be placed in the position illustrated in Figs. 3 and 4. These positions are formed by pulling the handle B to the rear and by revolvingzthe handle C2 aquarter of aturn, as shown. It will thus be observed that a direct passage is formed on either side of the deflectingdamper B, as shown at a5, and that after passing through the passage a5 the air and products of combustion pass directly to the sleeve a', through the spaces between the now vertical plates D D2 and detlecting-plate E.

Should soot or dust collect upon the plates D D D2 of the revoluble damper, the latter may be easily cleaned by turning said revoluble damper in the position shown in Fig. 3, and then agitating the handle C2 vertically, a suicient vertical movement being afforded to the shaft C by t-he slotted bearing c. v

The large cavities F on either side of the walls a4 andwithin the outer shell of the drum A serve as reservoirs, wherein a large volume of heated air is held in suspension, from which heated air the surrounding parts receive and impart heat that would otherwise pass out through the outlet-opening a.

Some of the advantages of my invention may be attained by dispensing wit-h the diaphragms or walls a4 and with the damper B, as the construction of the revoluble damper is such as to cause the smoke and heated air to pass very slowly through it and into the outlet-opening a. In this case it will be found advantageous, as will be obvious, to have the inlet-opening a attached directly to the ends c2 of the walls C, thus dispensing with the drum proper A. Such a construction, which is so obvious to those skilled in this art that I do not consider it necessary to illustrate the same, would be usually employed where it is desired only to use a damper in a length of stove-pipe and not for the purpose of heating a drum.

I claim as my inventionl. A radiator comprising a hollow'sheetmetal housing or drum having suitable openings for the inlet and outlet of heated air and smoke, a pair of diaphragms located within the drum near the inlet-opening, a damper located between said diaphragms, anda revoluble damper located within the outletopen ing, substantially as described.
