lMPROVEMEN'T' IN HEATERS.

Specication forming part of Letters Patent No. 49,1504, dated August 22,1865; antedated August 1 5, 1865.

To alt whom it may'conce'm:

Beit known that I, JOHN GHLLGOTT, of No. 70 Fulton street, in the city of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Hot-Air Stoves and Furnaces for'Warming Buildings l and Apartments; and I herebyV declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a longitudinal vertical section of a hot-air furnace in the plane indicated by the` lin-e w w in Fig. 2. Fig. 2 is a transverse vertical section of the same in the plane indicated by the line zz in Fig. 3. Fig. 3- is a longitudinal vertical section of thc same in the plane' lndicated by the line y y in Fig. 2. Fig. 4 is,

f This invention relatestostoves and furnaces for warming buildings and apartments by the introduction of heated air, or by producing a constant circulation of the air in the building or apartment by contact with the heated surfV faces of the stoveor furnace. f

Its object is partly to econom-ize fuel and partly to obtain a large heating-surface at a moderate heat, and thereby obviate the unpleasant ei'ects of very highly-heated surfaces; and to this end it consists,'rst, in surrounding an air-hcating chamber with a continuous system of flues, through which the gaseous products of combustion from a re below the said chamber are caused to circulate around and in contact with the exterior of the said chamber before passing to the chimney or uptake; sectn'dly, in providing within the said chamber aiontiuuous syste-n1 of flues, through which a portion of the gaseous products of combustion are caused to circulate back and forth on their way to the chimney or uptake, while a portion ot' such productsicirculates continuously back and forth in contact with the exterior of the said chamber. I

To enable others skilled in the art to make and use my invention, I will proceed'to describe it with reference to the drawings.

A is an air-heating cham ber of parallelopip- `edal or other suitable form, made of iron or# closed air-space, a, between them, which is filled with air to act as a uon-conductorof heat. Between tbe vertical sides of the chamber A and' the inner shell, O, there is a c ontinuons series of dues, b, which entirel surround the chamber,

and through which a portion of the gaseous products of combustion from the fire-place F below,` entering the casing B C through an opening,f,

(Figs. 2, 3, and 5,) in the bottom, will circulate entirely around the saidchamber before escap` ing to the chimney-D througha pipe, g, Fig.

1. The manner in which the lower flue, 1),.s

connected with the upper one to render the circulation of the gases continuous is repre-` 1 sented ath in Figs. 2 and 5...

Only two fines, b b, are represented, but there maybe three or more, so that the circulation ofthe gases may be three or more times entirely around the chamber A. 3

Between the shell B and the bottom of the.

chamber A there are ilues c c, through which another portion of the gases from thelire,`en-

4tering the casing B C through an opening, t,

in the bottom, circulate back and' forth one or more times before entering the continuous series of fines jk k. l, provided within and extending through `the chamber A, and Vfrom whence the said portion of the .gases escapes into a continuous seriesof flues, m m, between the top of the chamberA and the shell? B,a`nd` thencethrough a pipe, n, to the chimney D.

rlhe fines kik, which extend longitudinally and horizontally through the chamber A, are representedas only two in number, but their number is notlimited and by a proper number of 'themlband Va suitable arrangement of openings @,Fig. 1,at opposite ends alternately,

the gases-may be made to circulate hack andV forth through the interior of the chamber A.-

In the top of the air-heating chamber Athere.` is an opening, 1,coi11i'nnnicating withan open ing, e, inthe top of the casing B C, for the exit of the warmed air from thesaidchamber through'a pipe. or duct, E, whichtleads vinto the apartment or `apartments to bewarmed, with abranch, E', communicating to each apartment whenmore. than one is to be warmed by the same furnace, rlhi's duct'` is mede with double walls lto prevent loss,l of heat by radietion,

I have represented no means of introducing fresh air into the chamber A, as this may not be necessary,` an upward' circulation of the heated air from the said chamber through the duct E 4to the apartment or apartments t0 be warmed causing at the saine time e downward circulation of cooler air from the apartment through the said duct to the chamber A.

What I claim as my invention, and desire to secure by Letters Patent, is.-

1. Surrounding the air-heating chamber of a stove or furnace with e continuous system of tlues, b b, substantially as herein described, iu which the gaseous products of combustion from the fire nrc caused to circulate continuously two or more times completely around the said chamber before passing to the chimney, subv stantially as herein set forth.

2. In combination with lrhe continuous system of' ues b, surrouudiu g the sides of the airn heating ch amber, the continuous system of ilues c j 7c l m, under, through the interior of, and above the said chamber, substantially as herein described.
