HEATING APPARATUS.

ySpecification of Letters Patent.

Application led June 4, 1909. Serial No,`500,1l5,

asoma.

To all whom it 'may concern:

Be it known that I, ALBERT M. LoRENTz, a citizen of the United States of America, and resident of Mcll/l'echen, county of Marshall, and State of lest Virginia, have invented certain new and useful Improvements in Heating Apparatus, of'which the following is a specification.

This invention relates to heating apparatus, and more particularly to a heating device whereby one or more rooms of a building may be economically heated.

An object of the invention is to provide a stove, radiator, or heater, which embodies therein a plurality of baffles so constructed and disposed with relation to eachother as to forma tortuous passage for the products of combustion, means being thus providedwhereby the heat which' would otherwise escape through the flue and be wholly lost is retarded in its passage to the flue and is partially absorbed and radiated int-o the room in which the apparatus rests, or is absorbed by currents of air and conducted through suitable channels to another roo or rooms. l

A' further object is to provide means whereby an induced circulation of cold air through the heater structure is obtained, which air is heated by contact with the heated battles and is discharged directly into the room occupiedby the apparatus, or is conducted through one or more pipes to another room or rooms. 'l'

With these and other objects in view, the invention linally consists in the particular construction, arrangement and combination of parts which will hereinafter be fully described, reference being had to the accompanying drawings, forming a part of this specification, in which* Figure 1 is a front elevation of a heating stove embodying the invention, a portionof the hood being shown broken away ;4 Fig. 2 is a4 vertical section of. the same on line .f2-2, Fig. 1; and Fig. 3 is a detail perspective view of a batiie. v

In the present embodiment, the invention is shown and described as used in, or applied to, an ordinary type of gas heating stove; it will, however, be understood that the invention may be embodied in or applied to heaters and furnaces of widely different typs in which either gas or 'other fuel is use designating characters distinguish like parts,-

constituted lat the upper end of the" shellby closing the sides of the remaining portions or extensions adjacent to-said passages 4,'

as shown at 6, said fines alternating'withusaid passages il. The passages 45 are also if separated from' the interiorof the shell b v a Wall 7, they air which enterssaidfshell:atthe bottom being discharged from; thedopof the tlues 5 and not-mixingf` with the products o f combustion passing through theI structure. t

A second baiile 3 is locatedtothe` rear of l 1 said baliie 3 and is inclined away theref'roinf` rllhe battle 3 is, however,l`-1` nounted in yrea. r` versed position, having'f-lts yalternate passagest and thel flue's at thelower lend,y

thereof instead of at the upper end. Further batlies, such as 3a and 3, may be employed, as shown, in a series of any length, said baffles being' disposed in staggered relation-that is, adjacent battles having reverseinclinationse-and adjacent battles are disposed in reverse position.

From the foregoing'it will be apparent that the products of combustion emanating from the burning fuel in the combustion chamber 2 will be conducted through alter- .nate ascending and descending tine-like chambers located between said battles, said. products first passing through the passages llat the upper end of battle 3, whence thev travel down and through the passages'4 at the lower end of baille 3', thence rise' and l pass through the passages 4a at" the upper Referring to/said drawings, in which like l end of a Vbattle 3a, thence pass down andr through the passages 4 at the lower end of baille 3, whence they pass to and through the discharge tlue 8. ,In passing through the somewhat tortuous passage described, not

only is the heat which is seeking escape 'with y the other products of combustion retarded so that it will be lpartially absorbed by the wallsof` the casing and radiated therefrom throughout the room in which the heater is located, but said `escaping' heat plays directly upon the exposed'surface of theseveral shell-'like battles, inducing currents .ot air topass` upward therethrough, heating the latter,l and imparting heat to said'air. The induced currents of air pass' through perforations 9 in the top 10 intoran overlying inclosed heat-receiving chamber 11, from whichit may be conducted through one or more pipes l2'to a room or series of rooms for heating'the latterA 'f By inclining' the batlies and arranging them in staggered relation, I retard the passage yoflthe products of combustion to a much greater extent than would be the case if said battles were arranged lvertically or in parallel relation. Consequently, an increased proportion of .heat is extracted from the products otcombustion in the 'passage of the'latter through the device.

Having thus described my invention, what I claim vas new, and desire to secure by Letters Patent, is-

1. A heating apparatus comprising a casing', a combustion chamber at one side of said casing, a baille forming one wall of said chamber, a discharge fluefor the products of I combustion, a heat-receiving chamber over 4 lyingv said casing, and a plurality of hollow4 battles interposed between the first mentioned balilefand said flue, said battles being disposed in oppositely inclined relation to.

form a tortuous alternating ascending and descending passage for the products of combustionin ywhich they are successively eX- posed to the heat escaping with said .products of combustion, andy means embodied inv said baliles whereby the heat absorbed by the latter is communicated to induced currents ot air passing therethrough and not mingled with said products of combustion.

2. In a heating apparatus, a casing, a`

- therethrough, adjacent battles being inclined in opposite directions and being mountedin reverse positions, a heat-receiving chamber into which air is directed'from' said battles,

and conducting pipes leading from said chamber.

' 3. In a heating apparatus, a casing, a

combustion chamber within said casing, an`

inclined batlie forming one wall of said casing,'a discharge flue for the products of combustion, and a plurality of baffles interposed between the first-mentioned baille and said flue, each of said baffles comprising a hollow shell which is recessed at one end to form alternate passages for the products of combustiomi'rom one side ot' the battle' to the other yand chimney-like extensions, said baiiles' affording a free passage for the air therethrougli,'said batlles being inclined with relation to each other and being mounted in reverse positions forming an alternately ascending and descending'passage for the products of combustion.

In testimony whereof I affix my signature in presence of two subscribing witnesses.
