HEATING s'rovn.y
Appucatin mea Aprn ao,
so arranged as to facilitate the circulation of y air thereabout and hence increase the heating vefficiency of said stove. y
A further obfect of the invention is to be found in an improved arrangement and combination'of combustion chamber and flues, whereby the natural relative circulation of hot and cold air is utilized to enhance the efliciency of a heater.
A further object of the invention is to pro-V vide improved means for introducing unlieated air between the lower ends of spaced, vertically-disposed flues rising from and in combination with a combustion chamberto theend that such air may be heated by and rise between said flues to establish and maintain a circulation of air in and about a heater.
' A further object of the invention is to provide an improved flue construction for a heater, whereby unimpeded vertical circulation of heated air Imay, be had within and about said heater.
A further object of the invention is toprovide improved structural features to be ernployed in connecting spaced, 'vertically-disposed flues of a heater with'a smoke chamber. A further object of the invention is to pro- V vide a heater of the type hereinafter described that is inexpensive of manufacture,
simple of assembly, eliicient in operation and susceptible of being housed in anv ornamental easing without limitation of its efficiency.
My invention. consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which- V 'Y Figure 1 is a front elevation of a conventional combustion chamber equipped with my improvements and ready for practical use. Figure 2 is aside elevation of the showing of Figure 1, the major portion of the conventional combustion chamber being omitted to conserve space. 'Figure 3 isa plan view ofV the showing of Figure 2, a portion of the top plate being brokenaway to show interior construction. Figure 4 is a vertical section on the indicated linea-4 of Figure 3. Figure 5 is an isometric view of one of the struc'- tural elements employed in the improvement;v
192s. serial No. 273,902.
Figure 6 is an isometric View', on a reduced scale, of one ofthe im rovedlues employed in the improvement. IF ric view vof a portion of one ofthe cold air igure 7 is an isomet-V ducts employed in carryingout my invenfy tion.
In the construction of my improvement as shown, the numeral 10 designates a conventional combustion chamber or lireLboX having a hinged fire door 11, an ash door or tray 12, suitable supporting legs 13, abottom plate 14; and a top plate 15, the particular' arrangement shown being but-one simple combination of the recited elements, though any form v'of combustion chamber'suitable for combination withthe remaining elements'of'my improvement may be employed. The top plate 15 of the combustion chamber is provided with a vplurality of rectangular, laterally spaced openings 16 extending longitudinally from'front torear of said'plate, eachof said yopenings 16being'providecl with an upwardly-eXtending marginalflangejor collar 17, preferably formed integrallywith said plate. A plurality 'of rectangular 'iiues 18, in number equal to the openings 16 of the plate 15, are preferably formed of sheet metal' with open upper and lower ends andare of a size 'to slip on, and fit closely in telescoping relation about the flanges 17 of the openings 16,
' in such manner as to provide'communica'tion between the interior of said iues and the inrterior'o'fsaid`lire-boX through the saidopenings 16, such positioning of the flues 18 serv ing to mount them in spaced relation vertically on and extending upwardly above the top lplate 15 of the combustion chamber. A
plate 19 is mounted on-and'extends across the vupperopenends of the l'ues 18, closing said ends, downwarmy-extending integral flanges 2() of said plate 19 being received in telescoping relation within the upper ends'of the lilies 18, said plate'19 extending rearwardl beyond the rear edges ofthe tlues 18 and eing provided with rectangular *openings* 21' extending longitudinally of said plate 'and registering, in betweenA the flues 18, a collar 22, adapted to receive a smoke pipe, being formed on and rising from that portion 0f the said plate 19 extending rearwardly beyond the said llues.
The joints between. the plates l15 and 19andy the ends of the lues 18 may be cemented or otherwise sealed andthe assembly of said plates and flues may be rigidly secured and held together by means of bolts 23 passing spaced relation, "with the spacesy through and secured against the plates 19, or 14, or in any other suitable mannen The rear margins of the fines 18 are formed with'apertures 241 adjacent their upper ends and a plate is mounted beneath the plate 19 and transversely of the rear margins of the fines 18, said plate 25 being formed with apertures or slots 26 registering with the apertures 24- and also formed with integral ribs or flanges 27 positioned to overlap 'on either side of the edges of the apertures 241 and provide means of sealing the connection between the fines 18 and plate 25. liearwardly extending ears 28 are formed adjacent the ends of the plate and a smoke boi; 29, having an open top and an open side toward the plate 25, is secured to said ears beneath the extending portion of the plate 19 and behind the plate 25, the interior of said smoke box coinmunicating through the aperture in the collar 22 with a smoke pipe or stack. From the foregoing description, it is readily apparent that smoke, hot gases and flame generated in the combustion chamber 1() are free to pass upwardly through the apertures 16 into the flues 18, heating said fines, then pass rearwardly through the slots 26 in the plate 25 into the smoke box 29y and from thence, through suitable connections, to a chimney or other convenient out-let. The air around and between the flues 18 will become heated by the passage of smoke and hot through said flues, Said heated air being free to rise'as it expands through the apertures 21 of the plate 19 and circulate through the room or building to be heated, cooler air being drawn in between the fines 18 as the heated air expands and rises, thus establishing an emcient circulation of air between and about the said fines. In order to facilitate the circulation of air above described, air ducts 30, each formed with open ends and a plurality of holes or apertures 81 on `its upper surface, are mounted on and above the plate 15 between the vtlues 18, one end of each duct 8O preferably extending rearwardly and downwardly relative to said plateand toward the unheated stratum of air. The air ducts 8O provide means for introducing unheatcd or cooler air, which is drawn in through said duct at either' end and discharged through the vholes 31, between the opposed hot walls of the fines 18 where it is quickly heated and from whence it is free to rise, in a straight and unobstructed path, .through the apertures 21 of the plate 19, thus preventing undesirable eddies and obstructed air currents in and about the flues 18 and greatly increasing the volume of air heated by a given amount of combustion and hence enhancing the heating efficiency of the assembly.
Since many changes or modiications of specific form and construction may be made without departing from the spirit of my improvement, l wish to be understood as being limited by the scope of the appended claims rather than by the illustrative showing and foregoing description.
I claim as my inventionl. A heater comprising, in combination, a 'combustion chamber, spaced, vertically-dis posed fines on and rising from said coinbustion chamber and communicating therewith, a plate transversely of and closing 'the open upper ends'of said fines and extending rearwardly therebeyond, apertures' in said plate registering with the spaces between said flues, a smoke box transversely of the upper portions of the rear margins of said fines beneath the extending portionof'said plate and registering apertures in the front wall of said smoke box andthe rear margins of said lines.Y
