IMPRVEMENT IN RESERVOlPt-STOVES.

Speeiiieation forming partof Letters Patent No. 14,l83, dated Septcmb'l, 3.854,- f ,Y

To all whom it may concern:

Be it known that I, H. F. T. HALE, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Reservoir-Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable th ose skilled in the `art to make and use the same, reference being had to theaccompanying drawings, forming part of this speciication, in which- Figure 1 shews an elevation of my stove in section on a line, W, of Figs. 3 and 4. Fig. 2' shows another sectional elevation at right angles to the line W. Fig. 3 is aplan 'Y view of a section taken on a line, y, Figs. 1 and 2. Fig. 4 is a similar-view at the line x.

Similar letters of reference indicate like parts.

The outer case of the stove has been left oil'.

V It is therefore drawn in the several gures'in red outline, and is intended to embrace the inner parts and lines of the stove between the plates 1 and My improvement consists in'an attempt to make a more economical use of the products of combustion than can be made in the stoves in common use.

A represents the fuel reservoir, the mouth of which is closed bya cover, r. The wall of my lire-pot is made of Vertical hollow 'bars O, and bottom to allow the free passage of air. (See the arrows marked 3.) These bars open .below into the cold-airchamber C, and above into the annular chamber O', which is open above and en-v tirely surrounds the reservoir. 'lhe chamber C is U-shaped, and surrounds'the ash-.pit ou all sides, except its front, and is itself surrounded by the base-flue D E. Cold air from beneatl'r the 'stove is allowed to enter the chamber Cthrough holes in the bottornplate v ofthe stove. (Marked in dotted outline in Figs.

8 and 4.) Spaces g are left between vv-thevertical bars,0, through which the products of' combustion pass into an annular chamber, Q, surrounding chamber 0. Thischamber: Q is closed above by the top plate, 2, and the`direct-draft pipe E Fig. 1.'

on a line, z, i

opens into it,`as"shown in.- Vthoutl the chamber is another l annular chamber, C', opening below into the cold-air'chamber(l and extending to the height shown in Fig. 2,'where it is connected to open pipes c. (Shown in cross-section in Fig 4, and in Fig. 2 in longitudinal section.) The chamber C does not form a complete annulus, but .terminates at point 5, on the front ofthe stove, inline with the ash-door openings. The space thus left forms part of the Hue-space Q, and an opening, b, is made through the plate l of the stove, so as .to connect this flue-space with the ash-pit for the purpose of moderating the draft, if necessary. The hot-air pipe H also passes through this space from the hotair chamber O, in order to furnish the meansof securing a connection with. pipes leading thel hot air to other apartments.

T-hespaces between the walls of the small pipes c connect the annular chamber Q to lue's D, 'and the products of combustion are marked in Figa-2 as .passing from one-to .the other. (See the red arrows.) The annular chambers D are formed by the outside case, the position of which is shown in red outline-as l have not thought it necessary to do more than indicate yits location between the upperand lower plates,

2\and 1. The base-Haes D are formed'at the sides of the steve within theoutercasing of its lower part and the outside ofthe annular extendfrom the points 4 on each 'side of that chamber around toward the back part of the stove, until they reach the chamber E, which is merely a continuation of them. A pipe, f, connects the chamber E behindthe damper. The holes b shown in Fig. 3 represent the openings -from the annular chamber C in to the cold-air chamberfG.

Vis the bar aboutA which the horiztmtall grate ofthe lire-pot is rocked to dumpit. It passes between twoilat4 air-channels, one of which is shown in' Fig. .l at a', the ollce of which is to pass the 4chamber into the two front tubular grates, O O. (Shown inFig. 3.) AThese llat tubes w, of which there are two, extend from the cold-air chamberat cach side of the yasl1-pit, respect ively, under the plates 1 and along-the top of the'ash pit, until they communicate a supply -of air to those vertical gratebars which are chamber (l, and they situated above the front of the ashfpit, No
