3 Claims.
This invention, relating as indicated to a' fireplace heating system, is more particularly directedto thebombineition of a fireplace stove of novel construction and "a flue arrangement whereby products of combustion can be taken oiT through a stack or chimney, while'heated air can be radiated into the room containing the fireplace and also conducted to rooms abovethe fireplace.
itis an important object of the invention to provide a means ofheating theair which comes in contact with the fireplace stove and at the same'time utilizing the heat of the products of combustion as they ascend the chimney.
It is a more detailed object of the invention to provide a grate formed of hollow tubular members so that the fluid such as air may be efficiently heatedand expelled into the room in which the stove containing the grate is located.
Another object of the invention is to provide a grate of hollow tubular construction adapted to receive a fluid such as water, the grate performing the double function of maintaining thefire bed properly and at the same time heating water so that the same may be piped to a service outlet in the building'in which "the stove containing the grate is located.
A more detailed object is to provide means for conducting water from a hollow tubular grate to a service cutlet'in the building in which thestove containing the grate is located.
Another object of the invention is to "extract as much heat as possible fromth'ei-products of combustion as they ascenda flue, this extraction being performed by-means of a water tube located in the flue.
A detailed object of the invention is to provide a combustion chamber with an apertured base and a slidable plate mounted above the base to permit ashes to be withdrawn at'desi'red intervals of time.
A more detailed object *ofthe inventionis to provide an ash receiver somewhat in'the form of a drawer. this receiver having associated therewith a tined gratebar for removing clinkers and ashes from between the individual elements of the grate.
Another detailed object of the invention is to provide a fireplace stove with a two-piece fold ing door mounted in such manner that a rather large opening is provided when the door is opened, thus imparting'the Vi'sualaspect of a conventional fireplace.
upomfurther reading =of' the description.
2 The annexeddrawings and the following description set forth in detail certain mechanism embodying the'invention, such disclosed means constituting, however, but one of various mechan-ical forms in which the principle of the invention may be used.
In said annexed drawings:
Fig. 1 is a front elevation with parts in section.
-Fi g.--2 is a central vertical section taken transversely of Fig. 1.
Fig. 3 is a horizontal section taken just above the grate shown in Fig. 2.
Fig. 4 is a partial vertical section of the lower portion of the stove shown in Fig. 2.
Fig. 5 is a front elevation of a modification.
Fig. 6 is -a central vertical section of Fig. 5.
Fig. 7 is-a detail perspective showing the water system.
Fig. 8 is a rear elevation of the fireplace stove.
Fig. 9 is a horizontal section taken just above the grate shown in Fig. 6.
Referring now to the drawings, and more particul'arlyFigs. -1 to 3, it will be seen that I have provided a fireplace stove generally indicated by the-numeral i, such stove being connected to a flue 2 that extends upwardly in the chimney. A deflectingcplate 3 is mounted with its forward edge in sealed relationship with the upper interior horizontal edge of the fireplace. This deflector-extends arcuately down behind the stove L terniinating above the floor of the fireplace. It-is maintained in desired relationship with the walls 10, H and i2 by means of bolts 69 and ti.
This arrangement of the deflector 3 provides a space Ito the rear of the deflector, this space communicating with an annular conduit 5 that extends upwardly and surrounds the flue 2. From the foregoing, it will be seen that air is drawn beneath the stove l and then upwardly through the chamber i where it contacts the defiector 3 and fiue 2. This contact heats the air causing the sar'neto rise through the annular chamber 5. Partitions "6 and 8 are provided to cause'the air to flow through registers 7 and 8, it being understood that apart or all of partition 6 maybe omitted, depending upon the number of registers suchjas '9, which may be located above the register 1.
Referring now more particularly to the stove construction, it will'be seen that the base 59 is provided with a relatively large aperture and thatthe slida-ble plate 20 is mounted on the base immediately above the aperture. An ash recelv'r 2ll--is-'slidably disposed beneath the base and in-registiy withthe aperture in the base.
The ash receiver 20 has a slot in its forward surface to receive the shaft of a gratebar 2|. This gratebar is shown in Figs. 2 and 4 and comprises a shaft 2| connected to a cross piece 36, the cross piece having secured thereto tines 35. The tines are adapted to extend between the tubular grate members 22 to 34 inclusive when it is desired to remove ashes and clinkers.
Immediately above the removable slidable plate 20, I have provided a grate formed of hollow tubular members such as piping, each pipe extending transversely and in parallel relation with the other pipes as shown in Fig. 3. These pipes open to the atmosphere at the front portion of the stove as shown in Fig. 1 and are provided with elbows also open to the atmosphere as shown in Fig. 3. Air is drawn upwardly first, passing through the elbows and then across the grate and out into the room in which thestove is located.
I have also provided two additional sets of air conduits, these being located along the interior sides of the stove. Each of the conduits 40 to 45 inclusive extend upwardly from openings in the piece I5 and then are curved or bent to extend horizontally to pots in the front face of the stove as shown in Fig. 1. From this description, it will be seen that cool air is drawn from beneath the stove, heated in the combustion chamber and expelled out into the room in which the stove is located.
In the modified construction shown in Figs. 5 to 9 inclusive, the stove and flue are of the same general construction, as well as the air flow. That is, air flows around the stove, becomes heated and it is then deflected out into the room surrounding the stove. At the same time, some of the air passes beneath the stove, due to the provision of legs I5, I5, I! and I8. This air then passes under the lower edge I35 of thedeflector 503. As this air passes upwardly, it contacts first the relatively hot deflector and next the hot flue I02. Obviously, instead of losing heat, the air becomes hotter as it ascends and finally it is expelled outwardly through registers I? and I09.
The major difierences between the construction shown in Figs. 1 and is the grate which in the latter case is designed to receive relatively cool water and to heat the same after which it may be conducted to a desired point of use. The grate generally indicated by the numeral I20 comprises two parallel header members HI and I22 connected by a series of parallel cross tubes which are adapted to receive the fire bed. Water is admitted to the header I2I through pipe I23 but is prevented from passing immediately to the pipes I24 and I25 by means of a partition I26 located in the interior of header I2I. This causes the coldest water to pass across the grate to header I22 and after this, it may pass backward and forward, eventually leaving the grate through pipes I24 and I25. These pipes are located within the flue I02 and extract more heat from the products of combustion passing upwardly within the flue. A tank I29 is located in the upper portions of the chimney and this tank surrounds the flue I02. Heated water may be led from this tank to any desired service outlet.
In Fig. 6, one mode of usage is shown comprising a pipe I29 connected to a faucet I30. From the foregoing it will be seen that water arising in the pipes I24 and I25is maintained in heated condition since the flue will be relatively hot as long as the stove is in operation. At the same time, the water in tank I29 is maintained in heated condition since the air in the chamber I05 rises upwardly.
In both stoves, I have provided a firebrick located in the lower rear vertical portion thereof, this being identified by reference numeral 60 in Fig. 2 and by reference numeral I28 in Fig. 6.
The door is the same in both embodiments of the invention so that a description of one will suffice. Referring to Figs. 1 and 2, it will be seen that the door consists of two sections 46 and 41 connected by means of a hinge 48 in such manner that the panel 46 will overlie the panel 41 when the door is in full opened position. At this time, the rod 49 which is secured to the panel 46 is received in brackets 52 and 53. In opened position, the stove presents the appear ance of a conventional fireplace while there are no cumbersome doors to obstruct the view or to interfere with the normal function of the various parts. In closed position, the rod 49 is received in the brackets 50 and 5!.
Other modes of applying the principle of the invention may be employed, change being made as regards the details described, provided the features stated in any of the following claims, or the equivalent of such, be employed.
I therefore particularly point out and distinctly claim as my invention:
