UNITED STATES JOHN S. BYBNE, OF BERKELEY, OALIFDRNIA.
Application filed November 24, 1926. Serial No. 150,432.
The present application relates to improvements in fireplace heaters, and its general object is to provide, in combination with a fireplace, a heater that will not only allow heat to be sent into the room by radiation, but which also causes circulation of the air of the room thru the heating Zone of the fireplace. It is particularly proposed in this connection to arrange air passages in the side walls of the fireplace near the floor of the room connecting with a heater structure accommodated in the rear of the fireplace, which latter structure has tubular members associated therewith which pass directly over the fire so as to absorb heat units therefrom and discharge thru apertures in the fireplace wall arranged above the fireplace opening. It is further proposed to provide certain improvements in structure which do away with the necessity of using fire bricks in the rear wall of the fireplace and which, in other respects, render the fireplace furnace particularly effective. lVhile I haveshown only the preferred form of the invention, I wish to have it understood that various changes or modifications may be made within the scope of the claim hereto attached without departing from the spirit of the invention.
The preferred form of the invention is illustrated in the accompanying drawing in which Figure 1 presents a. front view of a fireplace having my heater connected thereto,
Figure 2 a vertical section thru the same taken along line 22 of Figure 3,
Figure 3 a horizontal section thru the fireplace taken along line 33 of Figure 2,
Figure 4 a section thru the furnace taken along line 44 of Figure 2, and
Figure 5 an enlarged detail view of the furnace as seen from line 5-5 of Figure 2.
The fireplace 1 is of the conventional type, except for the features hereinafter mentioned, and comprises an opening 2 and a bottom 3. The fireplace has side walls 4 which converge slightly toward the rear, and a rear wall 6 which is vertical along portion of its height, but which slopes forwardly in its upper, region as at 7. The conventional type of flue communicates with the top of the fireplace opening and allows the smoke from the fireplace to be discharged therethru. This flue comprises a passage way 10' and a depending wall 11 provides a smoke guard to prevent smoke issuing from the fireplace to enter the room forwardly thereof.
In constructing the rear wall 6, the fire brick, ordinarily provided therefor, are omitted, and passages 9 are provided in the side walls, which passages run parallel to the sides and terminate in transverse passages 11 adjacent the rear wall. The tiles 12 which form a facing for the fireplace at the front of the same are perforated as shown at 13, and the perforations communicate with the passages 9 to permit the entrance of air from the room into the passages.
A flat casing 14 is located between the side walls of the fireplace adjacent the rear wall thereof, and this casing is provided with lat eral apertures 16 permitting air from the passages 9 to enter thereinto. This casing 1a is open at its top as shown at 17, and the rear wall of the same projects forwardly and upwardly to follow the contour of the rear wall of the fireplace. The upwardly extending portion of the rear wall of the casing extends to a point as high as the masonr but it terminates at the flue and does not extend into the same. The front wall of the casing is scalloped to provide spaced semi-circular seats for the conduit elements 19, which conduit elements are bent in the front sections thereof as shown at 21 to rest on the scalloped seats and are flanged as at 22, so as to allow the flanges to be riveted or bolted to the front wall of the casing.
The conduits are somewhat more than semi-cylindrical in cross section as shown in Figure 4 and are provided with flanges 23 which flanges permit the conduits to be secured to the casing. The flanges of adjacent conduits preferably overlap. The conduits terminate at their upper end in tubular sections 24, which sections pass indirectly thru the draft Zone of the fireplace and are subjected to the heat of the rising products of combustion. These conduits offer a maxi mum amount of heating area. The conduits discharge in a substantially horizontal direction thru the depending wall which forms a smoke guard and thru perforated tiles 26 on the face of this depending wall, similar to the perforated tiles 12. It will be noted that this construction allows the heater to be readily installed in a fireplace and provides a furnace of very simple construction. The entire assembly is neat and attractive in its appearance and is particularly effective inheating air passing thru the fireplace. The air is drawn in thru the perforations 12 near the floor and enters the casing 1 1- where it is subjected to the heat generated in the fireplace. Being warm, it rises and passes thru the conduits 19WVl1lCl1 are arranged directly in the heating zone where the air is further heated until it is finally discharged into the room thru the upper apertures in the tiles 26. The arrangement of the casing in the rear wall of the fireplace allows the fire brick ordinarily required adjacent this rear wall to be entirely dispensed with.
It is obvious then that I have provided a fireplace which is simple in its construction,
inexpensive to manufacture, is unlikely to get out of order, and is well adapted to perform the services required of it.
I claim: I
A fire place having side walls, a rear wall, a depending smoke guard, said rear Wall having its upper portion forwardly and upwardly inclined, said fire place having passages in the side walls thereof, communicating with the room to be heated, and running parallel to the side walls and terminating in transverse passages adjacent to the rear wall; a fiat casing inserted between the transverse passages, and having lateral apertures ad acent to the bottomthereof :tor allowing the passage of air from said transverse passages into the casing; airear wall of said casing projecting forwardly and upwardly to follow' the contour of the fire place rear wall to the upper end thereof, a plurality of semicircular members extending outwardly and upwardly from the front wall of the casing; tubular members formed at the upper end of said semi-circular members; flanges on saidsemi-circular and tubular members in overlapping relation to each other so as to form enclosed tubular outlet passages from the upper end of the rear wall of the casing, said enclosed passages extending across the 'flue'opening and communicating with outlet apertures in said smoke guard.
In testimony whereof I affix my signature.
JOHN s. BYRNE.
