HENRY BUTLER FLINT, OF BETHEL, MAINE.

HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 402,153, dated April 30, 1889.

Application filed February 4, 1889. $eria1No.2-98,545. (N0 model.)

person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a sectional view representing my improved device in use in a building; Fig. 2, an enlarged sectional view showing the lower funnel of the drum or heater, the

sliding pipe being shown in side elevation and withdrawn from the chimney; Fig. 3, a

like view, the sliding pipe projecting into the chimney and represented as broken away; Fig. 4, a longitudinal section on line .2 z in Fig. 3; Fig. 5, a similar view showing the sliding pipe withdrawn, and Fig. 6 a vertical transverse section taken on line main Fig. 4.

Like letters of reference indicate corresponding parts in the different figures of the drawings.

My invention relates especially to means for utilizing the hot air and products of combustion which ordinarily escape through the chimney of a building for heating purposes; and it consists in certain novel features, as hereinafter fully set forth and claimed, the object being to produce a cheaper, simpler, and more effective device of this character than is now in ordinary use.

The nature and operation of the improve ment will be readily understood by all con- Versant with such matters from the following explanation.

In the drawii1gs,A represents the chimney of a building, and B a stove situated in one of the lower rooms thereof. A funnel, 0,.of the stove opens into the chimney in the usual manner. A metallic drum, D, is disposed in a room above that containing the stove B, and is connected with the chimney A by two funnels, E G, leading, respectively, from the upper and lower part thereof. A pipe, II, is fitted to slide longitudinally in the funnel E,

the outer end of said pipe being provided with a vertical plate, I), which closes said funnel when the pipe is withdrawn from the chimney, as in Figs. 2 and 5.

The pipe H is provided with a mouth or opening, d, on its lower side of a length equal to the width of the interior of the chimney A. A vertically arranged rod, f, is fitted to rotate in the pipe II by means of an annular flange, g, on its lower end, (see Figs. 3 and 6,) which works in a socket, h, within said pipe. The rod f projectsupward through the top of the pipe and a longitudinal slot, 1', in the funnel E, being provided on its outer end with a thumb-piece, 76-. A horizontally-arranged bar, 7., (see Figs. 4 and 6,) is secured centrally on the rod f, and is provided at each end with a downwardly-projecting arm, on. A horizontally-arranged flat bar, 19, is pivoted at q on each side of the pipe H, at the inner end thereof, said bars being adapted to be moved or swung laterally in said pipe. .One bar is provided with a longitudinal slot, 0'', situated in front of the vertical rod f, and the opposite bar 19 with a circular slot, 0', disposed at the rear of said rod, (see Figs. at and 5,) the arms m of the bar Z respectively work ing in said slots. 011 the rear or free end of each flat bar 19 is secured a horizontally-an ranged outwardly-projecting head or plate, 1, adapted to be projected laterally through the mouth (I of the pipe, and of such size that they will completely block the chimney A at either side of said pipe when so projected.

In the use of my improvement, the drum D being disposed in a room of the building, 'as described, if it is desired to utilize the heat escaping from the stove B, the pipe H is pushed out from the funnel E by means of the bar f, which slides in the slot t' in said funnel, until said pipe projects into chimney, as shown in Fig. 1. The flat bars 1) being in the position shown in Fig. 5, by turning the thumb-piece 7c and revolving the rod f from right to left the arms m of the bar I, secured thereto, move in opposite directions in the slots 4, thereby forcing said pivoted flat bars apart and projecting their heads tlaterally through the mouth of the .pipe, as shown in Fig. 4:. This practically blocks the chimney A, and directs the heated air, smoke, &c., from the stove through said pipe and funnel E into the drum. D, whence it passes back into the chimney through the funnel G, as inch-- cated by the arrows in Fig. l. The drum and its funnels expose a large surface within the room, from which the heat is radiated in a manner readily understood without a more explicit description. To open the chimney again the rod f is revolved from left to right, moving the fiat bars toward each other and Withdrawing the plates t within the pipe H. Said pipe is then moved back into the funnel E, the mouth of which is closed by the plate I), preventing the smoke from entering the drum, as shown in Fig. 5.

Having thus explained my invention, What I claim is- 1. In a heating apparatus, the combination of a drum provided with an upper and lower funnel opening in to the chimney, a pipe fitted to slide in the lower funnel and be projected into the chimney, and pivoted bars in said pipe having head-plates adapted to be proj ected into the chimney, whereby the heated air in said chimney may be directed into said drum, substantially as described.

2. In a heating apparatus, the combination of a drum-provided with funnels opening into the chimney, a sliding pipe in one funnel adapted to be projected into the chimney'and provided with a mouth, pivoted bars in said pipe provided with horizontal head-plates, and a rotating rod in said pipe having arms working in slots in said bars, whereby they may be moved to project their heads laterally into said chimney, substantially as and for the purpose set forth.

3. In a heating apparatus, the combination of a drum provided with funnels opening into a chimney, a pipe fitted to slide in one funnel and be projected into said chimney, a mouth in said pipe, two bars pivoted within the pipe and provided with head-plates adapted to be projected laterally through said mouth, a rotating rod in said pipe, and a bar on said rod provided With arms working in said pivoted bars, whereby they may be actuated as said rod is revolved, substantially as described.

4. In a heating apparatus, the combination of the drum D, provided with the funnels E G, the pipe H, fitted to slide in the funnel E, and provided with the mouth 01, the bars 1), pivoted in said pipe and provided with heads t, and means, substantially as described, for actuating said bars to project their heads through the mouth of said pipe.

5. In a heating apparatus, the combination of the drum D, provided with the tunnels E G, the pipe H, fitted to slide in the funnel E and having the mouth at and plate I), the bars 1), pivoted in said pipe and provided with the heads t, the rod f, fitted to rotate in said pipe and projecting through the funnel-slot i, and the bar Z on said rod provided with the arms m, Working in slots 9 in said pivoted bars, all being arranged to operate substantially as described. I

6. In a device of the character described, a tube fitted to slide in a drum-funnel and be projected into a chimney, said tube being provided with pivoted bars having head-plates adapted to be projected through the mouth of the tube and block the chimney, whereby the heated air arising therein may be directed into said drum, substantially as described.
