Letters Patent No. 114,533, dated May 9, 1871.

IMPROVEMENT IN BASE-BURNING STOVES.

The Schedule referred to in these Letters Patent and making of the same.

To all whom t may concern Be it known that I, ROBERT DIVEN, of Williamsburg, in the county of Kings and State of New York, have invented a new and useful Improvement in Heating andiYentilating-Stoves, of which the following is a full, clear, and eXact description, reference being had to the accompanying drawing forming part of this specification, and in which- Figure l Yrepresents a sectional elevation taken, as indicatedl by the line x x in fig. 3, of a stove constructed in accordance with my invention 'Figure 2, a further sectional elevation of the same through the line y y, looking in direction of the arrow u Figure 3, a horizontal section through the une w w n-g. l; and

Figure 4, a horizontal section through the line z z in tig. 2.

Similar letters of reference indicate corresponding parts.

My invention consists in a novel construction of the fire-pot and its inclosing chamber or chambers, whereby an effective heating surface is obtained for the air passing up through the Ventilating-duets or passages, and the heat as produced by a downward draught is distributed over the front and sides of the stove.

The invention also comprises a novel arrangement of an annular base-flue extending wholly around the base of the stove, and between the tire-pot and ashpan.

Referring to the accompanying drawing- A represents the base of the stove, which is com structed with au annular flue, a, extending all around the stove, and communicating with a chimney, B, in the rear.

O is the ash-pan or pit, and

D a passage under control of a register in front for the introduction of air to keep up combustion, and that is heated by said passage in its way to the ire or to a chamber, D', arranged below the grate, and where said air becomes more highly heated.

E is the iirepot,1nade with three or more sides, but which is here shown as having four sides, rounded at their junctions as at b, and bellied inward intermediately, as at c.

This tire-pot is disposed within a chamber, F, of corresponding eontiguratiou-thatis, with rounded side junctions b, and intermediately inner bellied portions e,- but the corresponding portions of these two structures are arranged interinediately of each other, so that the portions I1 of' the fire-pot touch or approximate the bellied portions c of the structure F, and the portions b of the latter are opposite the portions c of the {ire-pot.

A cylinder, G, encirclcs the outer structure F, and the two structures E and F are so disposed therein that they form vertical passages d up the sides and front, or sides, front,and rear ofthe stove, which passages communicate with the annular flue a below and.-

through` a'perforated plato, H, or other suitable openings, with the combustion-chamber I, above the lire-v ity of the heated base both as regards its heating of the passage D and chamber D', and in other respects.

K is the feeder in the upper portion of the stove, and connecting with an annular perforated gas-burner L, in the combustionchamber I, which is supplied with partially-heated atmospheric air by connecting it, as by branches oropenings j', with one or more of the upper sets of veutilatiugtubes J Y What is here claimed, and de'sired to be secured by Letters Patent, is-

l. The combination, lwith the cylinder G, of the {irepot El and inclosing structure F, constructed and arranged to form downward ilues d at the front and sides of the stove, and intermediate hot-air passages e, substantially as specified.

2. The base due a, extendingientirely around they stove, and arranged iu relation to the ash-pan as described, in combination and in communication with the flues d, extending down the front, back, and sides of the latter, substantially as shown.

' ROBERT DIVEN.
