V,GAS-HEATER. Y
TOSaZZ whom z' may concern:
Be it known that I, LOUIS T. I-IAGAN, a citizen of the United States, residing yat Winchester, in thecounty of Clark and State of Kentucky, have invented new and useful Improvements in Gas-Heaters, of which the following is a specification.
My present invention relates to improvements in gas heaters, and the primary objects are to provide an improved heater of this character which is capable of operating with relatively high efficiency to transmit heat therefrom to the air of a room or other chamber to be heated, the lheater being provided withmeans for insuring an efficient draft therefor when rst started and when the heater is operated with a relativelylow flame.
To these and other ends, the invention consists in certain improvements, and combinations and arrangements of vparts,"all las will be hereinafter more fully described, the plointed out particu` novel features being larly in thecl'aims at t cation.` l In the accompanying 'drawing:- Figure 1 is a front elevation, partly in section, of a gas heater constructed iny accordance with the present invention;
e end ofthe specifi- Fig. 2 represents a vertical section through the heater, as shown Fig.,.1, and looking toward the left; c y d Fig. 3 shows one end of the 'heater as viewed from the rear;
Fig. 4 is a detail view showing'one of the return iiues in vertical section; .j
Fig. 5 represents, on an enlarged scale, a section on the line 5-,5 Vof Fig. 4;
Fig. 6 is a top plan view of one of the flues; y
Fig. 7 represents a crossjsection through one of the flues on the line 7-7 of Fig. il.
Similar parts are designated by the same reference characters in the several views.
The preferred construction is illustrated in the accompanying drawing and will be hereinafter described in detail. It is to be understood, however, that the invention is not restricted to the precise construction shown, as equivalent constructions within the scope of the annexed claims may be used and will be covered thereby.
In the construction shown, the heater is of a type adapted to use natural or other gas and is set into an ordinary open fireplace,

1 designating the hearth, 9 the front wall of the chimney, 'the yrear wall of the chimneyor fire-place, and 4 the flue of the chimney. The heater comprises an exterior' casing embodying a top wall 5, a rear wall 6, which latter isxpreferably spaced a suitable distance in frontv of the wall 3, and Ventilating or'perforated plates 7 and 8. A burner or fire-back 9 is suitably fixed within the casing, preferably at a point infrear of the perforated Ventilating plates l7 vand 8, and thisburnerror fire-back can be of any suitable construction and appropriatel connectedv to a'isource of gasV4 supply. f n the present instance, the burner or fire-back 9 is supportedv at its rear end by a ledgeI i 10 which extends rearwardly from the topy of the lower perforated plate 8 and its upper end is supported by a rearward extension `l1 of a cowl 12, the latter overhanging the com;
bustion chamber which is formed in frontof the Vburner'orl fire-back V9.
' According to the vpresent invention, yheat is' radiated n'otonly directlyfrom the flame produced gin front of the burner or fire-back 9, but is alsoradiated r from la suitable number of iiuesrthrough which the products of combustion from the burnery pass lon their way to the chimney, the'heat being absorbed from the4 flues by airwhich circulates past them, such -air entering the casingthrough the lower perforated pla-te`8 and iiowing into the roomv through the upper perforatedplate- 7. In the construction shown, a number' of ilues having return bends are ,arranged within the' casing of the heater and they serve asconduits through'which the prod' ucts ofl combustion fromV the burner pass tothe chimney. Preferably, each iiue is cornposed 'of a pair of concavedsheetjmetal-sections 13 and '14 which may be stampedV into` shape and united atv their marginal edgesVIV by seams 15 and 16. Each flue ris formed with an inlet 17, a down bend 18, an up bend 19, and an exit 20, thel eXit of each iiue eX- tending through an opening 2l formed in the upper portion of the rear wall 6 of the heater, and the inlet end 17 of each flue is secured or attached to the member 11. Each of these return iiues offers a considerable surface to the air circulating through the casing of the heater. In order to increase this radiating surface, a pair of fins 22 is preferably secured to the upper seam 16, and also a channeled plate 23, the flanges of which eXtend upwardly, is secured in position at the point where the inlet 17 of the fiue is connected to the member 11. In the present instance, the channel-shaped member 23 is formed with an opening through which the inlet end ofthe flue passes, and after the flue is passed through the member 11, it may be flanged, as at 24:. rIhe outlet or exit end 20 of each flue may be similarly flanged, as at 25, to secure it to the rear wall 6 of the casing.
The present invention provides simple and eiiicient means for insuring the necessary draft for the burner when the same 1s first started and also when the heater is operated with a relatively low iame. It consists in providing a direct passage having a less capacity than that of the return bend flues for the flow of some of the products of combustion to 'the chimney without requiring such products of combustion to flow through the return bends 18 and 19. This direct or by-passage 26 is always open and it is preferablyv formed in each flue by concaving the flue sections 13 and 14k at the point between the inlet 17 and exit 20. In consequence, when the burner is first lighted, some of the heated gases or products of combustion will enter the inlet 17 of each flue and will then Vfiow directly through the bypass Q6 and to the chimney, thereby heating the air or gases in the chimney to a degree suflicient to induce a draft which will draw the major portion of the products of combustion through the return bends 18 and 19 of the flues. The same action occurs when the burner is operated witha relatively low flame, with the result that a positive circulation of the heated gases or products of combustion through the return bends 18 and 19 of the flues is insured and the relatively large heating surfaces thus provided afford ample opportunity for the absorption of heat by the air which enters the lower perforat-ed plate 8 and which discharges from the casing through the upper perforated plate 7. It is to be understood that, in operating the heater at its normal capacity, only .a portion of the heated gases or products of combustion flow through the by-passage 26, the major portion of the gases or products of combustion flowing through the returnbends of the iues.
I claim as my invention 1. In a heater of the class described, the
combination with a casing having a combustion chamber and an air inlet at the bottom and an air outlet at the top thereof, of a row of iues arranged in spaced relation within the casing and forming between them vertical air passages connecting the air inlet and outlet of the casing, each flue having return bends leading from the combustion chamber to the chimney exit and each iiue also having a by-passage of a capacity less than that of the return bends of the flue and leading directly from the combustion chamber to the chimney exit, said return bends and the lay-passages of the flues forming communication at all times between the combustion chamber and the chimney eXit.
2. In a heater of the character described,
a flue comprising a pair of complementalY necting them, and ccmplemental ribs forni- K ing a dividing partition between said return bends, said ribs being shallower toward their upper ends to form a by-passage directly connecting said inlet and exit.
3. In a heater of the class described, the combination with a casing containing a combustion chamber and having an air inlet at the bottom and an air outlet at the top, of a row of upright laterally spaced flues arranged within the casing and spaced laterally to provide upright air passages connecting the air inlet and the air outlet of the casing, the passages of the iiues being connected to receive the products of combustion from the combustion chamber, and heat radiating fins proj ecting laterally from the tops of the flues across the air passages between the flues.
In testimony whereof I have hereunto set my hand in presencek of two subscribing witnesses.
