FIRE PLACE HEATING SYSTEM 7' Charles Goulding, Sr., Tampa, Fla. Application June 4,\11953,* Serial No. 3595455; lCl'ttim; (l". 126- -123) Thisinvention-pertains--to--heattransfer devices, and more particularly-,to"heatingmeans adapted to be utilized inconjunctionwith fireplaces of conventional design and construction;-

Oneof the primary objects ofthis invention is to provide a heating system-which may be assembled as i a unit for immediate installation -within a-- fireplace, or-which may be shipped in knock-down'form for assembly in situ.

Another -object-of this invention is toprovide a heating system of the type described which includes a prime heater, a heat accumulator or economizer, and a flue adapter, connected together to provide a sinuous path for the heat combustion products whereby the optimum amount of heat transfer is achieved between the system and the ambient atmosphere.

Other and further objects and advantages of this invention will become apparent from a consideration of the following specification when read in the light of the annexed drawing, in which:

Fig. 1 is a front elevation of a conventional fireplace and of a heating system constructed in accordance with this invention;

Fig. 2 is a top plan view, taken on the line 2--2 of Fig. 1 looking in the direction of the arrows, and illustrating the disposition and arrangement of component elements of the heating system to which this invention relates; and

Fig. 3 is a cross sectional view taken on the line 3-3 of Fig. 2 and looking in the direction of the arrows.

Referring now more specifically to the drawing, reference numeral 1 indicates, in general, a conventional fireplace formed of brick, stone or other desirable materials. In the embodiment herein disclosed, the fireplace 1 includes a pair of oppositely disposed, longitudinally spaced and parallel side walls 2, 3, which connect at their inner edges with a pair of inwardly converging baflle walls 4 and 5, respectively. The adjacent inner edges of the bafiles 4, 5, are, in turn, connected with the opposite ends of the back wall 6 positioned substantially parallel to the open face of the fireplace 1. As is clearly seen in Figs. 2 and 3, the base 7 of the fireplace 1 is provided with an exterior apron 8 longitudinally co-extensive therewith. In accordance with conventional practice, the fireplace 1 is provided with the customary chimney 9 including the well 10.

The heating system forming the subject-matter of this invention may be basically described as comprising three main substantially hollow, spaced and parallel heat transfer compartments consisting of a primary oil burning heater 11, a heat accumulator or economizer 12, and a flue adapter 13, all constructed of metal or other materials having a high degree of heat of conduction and having substantially rectangular transverse and longitudinal cross sectional configurations.

The primary heater 11 is provided with a bottom wall to which is rigidly secured the lower end of a centrally positioned oil burner support 15. The upper end of the support 15 terminates in an inwardly extending integrally formedannularflange. 16. The annular flange lfiisnugly, receives therethrough the cylindrical casing 17 et an oil, burner generally designated by the reference:numeral18, preferably constructed in accordance with the teachings of my patent, No.- 2,154,567, which issued on April 18, 1939. Theupper-end-of the casirig..17 is formedwith a. radial. flange or shoulder 19 which is superposed on the annular. flange 16 and maybe:fixedlyor.removablysecured there: in. The'lower end ofthe oil. burner 18.is.provided.witha fuelsupply conduit:20 which.projects laterallyfrom, one side wall 21.,of the heater 11. andis connected with a fuel source to bedescribed Theaupper. end Y 22 of-.the heater 11 is centrallyapertured'at 23 toaffordignition access to theoil'burner 18, .the .aperture beingnormally closed bythe .cap,24..

Theback wall25f of the primary heaterll is provided with .apairof horizontally, spaced and aligned apertures,- 26,27,1whichreceive therethrough one endof the eonv duits 28, 29., .respectively. The other-ends of :thecon-t duits 28, .29 are connected tothe interior of the: heat accumulator. .or .economizer .12 through suitable apertures. (not shown). formed ,-in sand adjacentto the upperencl. ofjtsfrontwall 30. As is clearlyshown in Figs; 2 and 3,- thebackiwall 31.,of the heat accumulator 12 and the front wall 32of the flue adapter 13 are provided with spaced aligned apertures adjacent to their lower ends and are adapted to receive therein opposite ends of a connecting pipe 33 having a larger diameter than either of the conduits 28 or 29.

The upper end of the flue adapter 13 is formed with a reduced neck portion 34 which connects with an elbow pipe section 35 projecting upwardly through a transverse fireplace throat sheet 36 for coupling with a plurality of flue pipes 37, 38 disposed within the chimney well 10.

As seen in Fig. 2, the fuel supply conduit 20 is connected directly with a conventional fuel control unit 39 having a manually operable control valve means 40. The control unit 39 connects, in turn, through conduit 41 with an oil fuel reservoir 42 rigidly supported by brackets 43 which are fixedly secured to and project laterally from the side wall 21 of the primary heater 11. Preferably, this assembly is positioned to the right of the system as viewed in Fig. l.

The heating system units and their component parts are of such dimensions as to permit the heat accumulator 12, the flue adapter 13 and a substantial portion of the primary heater 11 to be substantially surrounded by the side and rear walls of the fireplace 1. The entire system is supported above the fireplace base 7 and apron 8 by adjustable legs 44.

A guard screen 45 extends across the open face of the fireplace 1 and is provided with a grill 46 at the left hand side thereof as viewed in Fig. 1. Directly behind the grill 46 an electric fan 47 is secured on suitable mounting means to base 8, whereby air from the ambient atmosphere may be drawn into the fireplace 1 and circulated between the units 11, 12 and 13, and the air having become heated through contact therewith is reflected outwardly from the side walls 2, 3, baflles 4, 5, and rear wall 6.

The maximum of heat exchange is achieved by forcing the products of combustion through a sinuous path through the units 11, 12 and 13 whereby the heated gaseous and solid particles of combustion are scrubbed against the Walls thereof.

From the foregoing description it is seen that by rigidly connecting the heat exchange elements of this system together, together with their component parts, the system may be preassembled and installed as an integral unit, or if desired, it may be packaged in knock-down form and assembled in situ. In either form, the system is noncomplex in construction and assembly, requires little V 3 maintenance, and is relatively inexpensive to manufacture.

Having described this invention in detail, it will be understood that the embodiment thereof herein disclosed and illustrated is offered by waylof example, and that the invention is to be limited only by the scope of the following claim.

Iclaim:
