- .3Claims. (Cl. 237 -55) This invention relates to a fresh air heater and circulator, the general object of the invention being to provide means for heating air by the products of combustion passing from a heating device 5 through a chimney and causing the heated air to enter a room or the like.
Another object of the invention is to provide means whereby fresh air from the exterior of a building can be heated and passed into a room or the air in a room can be heated and returned to the room.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.
In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:
Figure 1 is a vertical sectional view through a portion of a building, showing the invention in use.
Figure 2 is a vertical sectional view through one of the tubular members of the device.
Figure 3 is a section on line 3-3 of Figure 2.
Figure 4 is a view of the top chimney plate.
Figure 5 is a sectional view through Figure 4.
Figure 6 is a top plan view of the smoke receiving box.
Figure 7 is a vertical sectional view through said box.
Figure 8 is a fragmentary vertical sectional view showing a joint between one tubular member and another.
Figure 9 is a sectional view through a register and showing the shutter means therefor.
In these drawings, the letter A indicates the furnace or other heating device and the letter B indicates a chimney and the letter C indicates a room in a building. In carrying out my invention, I provide a smoke box 1 which fits snugly in a lower part of the chimney and has a bottom flange 2 which extends between some of the bricks of the chimneyso that the box is supported in the chimney, as shown in Figure 1, and a nipple 3 is formed on the box and extends from one side thereof through a hole in the chimney and receives the pipe 4 which leads the products of combustion from the furnace into the box. This pipe 4 is provided with the usual damper 15. Tubular members 6 have their lower ends fitting over the nipples 7 formed on the top of the box andtlie upper ends of thetubular membersfit over the nipples 8 depending from a-plate 9 hav ingitsed'geslocated between'some of the bricks of the upper part of the chimney, as shown in Figure 1. Thus the products of combustion from the furnace pass into the box and then flow upwardly through the tubular members and pass through the openings 10 of the plate and then continue up through the chimney. These tubular members are provided with the fins 11 which are shown as arranged horizontally in the drawings, but which may be otherwise arranged, if desired.
Upper and lower registers 12 open out into the room and are in communication with that part of the chimney between the box 1 and the plate 9 and a pipe 13 leads air from an exterior part of the building into a tubular member 14 located in an opening in the lower part of the chimney above the box 1, so that this fresh air is delivered into the space in the chimney formed between the box 1 and the plate 9 and this air, coming in contact with the tubular members 6 and their fins 11, will be heated before it passes from the space through the registers 12. A damper 15 is located in the pipe 13 for controlling the passage of fresh air therethrough.
Thus it will be seen that I have provided means for utilizing the heat from the products of combustion passing from the furnace or heater A through the chimney for heating fresh air and thus the heat of the products of combustion which ordinarily is wasted is utilized for providing auxiliary means for heating thebuilding.
If desired, the damper 15 can be closed and the air in the lower part of the room will then pass through the lower register into the heating space and then pass from the space back into the room through the upper register.
Figure 9 shows shutter means 16 operated by the member 17 in the registers.
Figure 8 shows means for providing an air-tight joint between the sections of the tubular members and between the tubular members and the nipples and as will be seen, the section 6 fits in the section 6" and a shoulder 18 is formed on the section 6' to form a seat for a gasket 19 which also acts the end of the section 6".
- It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.
It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided.
that such changes fall within the scope of the appended claims.
What is claimed is:
1. In combination with a heating device for a building and a chimney, a box located in the lower part of the chimney, means for introducing the products of combustion from the heating 2. In combination with a heating device of a building and a chimney, a box located in the lower part of the chimney, a conduit leading from the heating device into the box, an upwardly extending nipple connected with the top of the box, a plate extending across an upper part of the chimney and having a depending nipple, a tubular member connecting the two nipples together and having fins thereon, a pipe for leading fresh air into the chimney space above the box, a damper in said pipe, and registers arranged one above the other in the chimney and connecting said chimney space with an interior part of the buildmg.
3. In combination with a heating device for a building and a chimney, a box located in the lower part of the chimney, means for introducing the products of combustion from the heating device into the box, 'a plate extending across the upper part of the chimney, a tubular member connecting the top part of the box with the plate, said plate having "an opening therein for placing the interior of the tubular member in communication with that part of the chimney above the plate, controlled means for introducing air into the chimney space above the box, and registers for connecting said space with an interior 20 part of the building.
