STOVE.

SPECIFICATION forming part of Letters Patent No. 557,071, dated March 24, 1896.

Application filed November 29, 1895. Serial No. 570,569. (No model.)

To all whom it may concern.-

Be it known that I, CARL LoUIs I-IOEMANN, a subject of the King of Saxony, and a resident of Chemnitz, in the Kingdom of Saxony, German Empire, have invented certain new and useful Improvements in Stoves, of which the following is a full, clear, and exact description.

The present invention consists of an improved stove in which, by a suitable arrangement of flues or dampers, the upper or lower combustion system may be employed at will; and in order to render the present specification more easily intelligible reference is had to the accompanying drawings, in which similar letters denote similar parts throughout the several views.

Figure 1 is a side sectional elevation, and Fig. 2 a front sectional elevation, of the stove arranged for upper or top combustion. Figs. 3 and 4 are similar sectional elevations showing the stove when the column of fuel is burned from the bottom. Fig. 5 is a section on line a b of Fig. 1, and Fig. 6 a detail View of the dampers.

e is the shell of the stove; r, the basketgrate, having suitable known means for sh aking the same.

f is the fuel-receptacle, having feed-chute 2., adapted to be closed by a swinging door k, which may be secured in position by suitable means. At the upper part of the receptacle f are arranged lateral downwardly-opening hinged doors, by means of which the stove may be adapted to work with upper or lower combustion.

P is the ash-pit, w a heating-chamber, and

m the connecting-pipe to the chimney.

If it is desired to burn the fuel at the topon the fill-regulating system the dampers 00 are thrown open, as. shown at Figs. 1 and 2, so that the downward passage in the stoveshell of the combustion-gases is stopped, the dampers x closing against the sides of the shell, so that the combustion-gases pass round the chamber w to the chimney.

If the dampers 0c are closed, as shown at Figs. 3 and 4., the combustion-gases will pass from the bottom of the column upward exteriorly of the fuel receptacle, round the chamber w, and out at the chimney m.

The fuel-receptacle may be of circular, square, rectangular, or other section.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is performed, I declare that what I claim is In a stove, having'a mantle e, a fuel-receptacle therein, a basket-grate under said receptacle, a feed-chute with hermetic closure to said fuel-receptacle suitable heating-chamber w and chimney connection m, the combination of suitable lateral downwardly-open ing flues or dampers as which when open close the lateral spaces at the sides of the fuel-receptacle between this and the shell in the manner and for the purpose, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two subscribing witnesses.

CARL LOUIS HOFMANN.
