IMPROVEMENT IN BASE-BURNING STOVES.

Specification forming part of Letters Patent o. 100,322, dated March 1, 1870.

To' all whom it 'may concern l Beit knownl that we, J oHN S. PERRY and ANDREW DIoKEY,of Albany, in the county f Figure l, Plate l, is a section taken laterally and vertically through the center of our improved stove. Fig. 2Plate l, is a section,

taken in a vertical plane through the center ofthe stove from front to rear. Fig. 3, Plate l, is a section, taken in the horizontal plane indicated by dotted lines x x in Figs. l and 2, looking upward. Fig. 4, Plate l, is a section, taken in the horizontal plane indicated by dotted lilies Y Y in Figs. l and 2, looking downward. Figs. 5 and 6,.Plate 2, are views of the stove as seen externally. Fig. 7, Plate 2, is a section, taken through the stovein the horizontal plane indicated by dotted line x1 in Fig. 5. Fig. 8, Plate 2, is a section, in the horizontal plane indicated by dotted line m2 in Fig. 6.

Similar letters of reference indicate vcorresponding parts in the several figures.

This invention relates to'certain novel improvements on magazine stoves and furnaces, which have their nre-chambers inclosed at the sides by a case or wall, provided with doors and mica windows'.

The main object of our invention is to em-v ploy an external revertible ue in combination with stoves of the class above referred to, and to so construct and arrange the external fines that the products of combustion can be carried out horizontally from the combustionchamber, thence conducted down into, and caused to circulate through, the base section of the stove, thence backward and upward to the main exit-pipe. Said products, in their descent or on their way to the hollow base, will communicate considerable heat to the ascending-iiue, and thus greatly augment the draft, as will be hereinafter explained.

The following description will enable others skilled in the art to understand our invention and a practical mode of carrying it into effect.

In the accompanying drawings, Plates and 2, A represents the base section of the'y stove. B is-theash-pit section; C, the illuminating or window section; D,.`the interme-` diate section between the section C and top section E, and F is the cover to said top section. At the back of the base section A is a rear chamber, t, from which rises the escape- `pipe Pthat communicates with the interior of Y section D when the direct-draft damper u. is open. The base section A is hollow and divided into two iiuefspaces by a curved plate,

M, shown in Figs. l, 3, and 4. 0n one side 'lhe plate .M extends forward nearly to the frontof the base section A, so thatall the heated products whichv enter this base seotion V.through the descending flue i" are di rected forward ,to the front of the stove before they can return to the ascending iiues or chambers. This is indicated in the two Figs.

3 and 4, Plate 1, by the course of the arrows.

The descending or diving ue r is an oblong iiue constructed on the back side of the ash-pit section, outside thereof'. It opens above into the combustion-chamber of section G by means of a passage, z, which occupies nearly the entire vertical height of said section, and one fourth, more or less, of its circumference. At its lower end the descending flue r opens on one side of the division-plate M, as shown in Figs. 3 and et. The ascending line t is formed by the section S, which is constructed upon the back side ofthe flue r', and f which communicates superiorly with the fluepipe P, and inferiorly with hollow base A, on that side of division-plate M which is opposite the descending flue-inlet.

It will be seen` that chamber t of section S will receive considerable heat from the products descending through ilue r', which will rarefy the air in said chambers, and thus produce an artificial outward draft.

Within the ash-pit section B the fire-pot J is suspended so as to leave a space all around it. This pot J is suspended by its perforated flange j, upon which flange is arranged a movthe direct damper 'it' is open or shut. Below zine, which section is surmounted by the u-pable perforated ring or register, d. By means of this register-rin g, which we do not claim as our invention in itself considered, air can be allowed toenter the combustion-chamber from the ash-pit in any desired quantities whether per section E, that is covered on top by the sliding or lifting cover g. On the top of the magazine is a chamber, G, having its sides Haring upward and the upper edges thereof scalloped, as shown in Figs. 1 and 2. This chamber is within the top section E of the stove, and is closed on top by the cover F to said section. It affords a space for boiling waterand cooking, and is in communication with the chamber surrounding it and the magazine.` A Hue, N, is constructed on the back part of the section D, and closed by a bottoln wall` and two vertical side walls. Its upper end is open, and communicates with the iiuespace surrounding the magazine and oven, so that when the damper n', in cross-pipe N', is open a communication for direct draft is established between the combustion-chamber and flue-pipe P.

From the above description it will be seen that when the direct-draft damper n' is shut all-the produetswill be caused to circulate through the hollow base A and through the descending and ascendin g lues, and that when this damper n' is open all the products will pass upwardly through the chamber between the magazine and outer wall and oven and top, and thence escape through pipe N' into the pipe P.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The due-passage r' and t, arranged at the back of a suspended fire-pot, J, and communieating with the back of a hollow due-base, A, directly beneath described.

2. The arrangement of flue outlets ^r and n', in combination with lues fr', flue-base A. flue t and iiue P, substantially as described.

3. The direct-draft damper fn.' and its pipe N', in communication with escapefpipe l), and in combination with the indirect-draft descending fine o', due-base A', and ascending ilue t, substantially as described.

4:. The descending and ascending ilues vand hollow base, constructed as described, in combination with the register-ring on fire-pot J, substantially as described.

5. The combination ofthe following elements, to wit, a suspended lire-pot, alue-base, A, and lues leading into and out of this base, substautially as described.
