2 Claims.

This invention relates to heating systems and has particular relation to a heat distributing means for hot air heating systems.

The present invention is more particularly applicable to forced air heating systems. The systems of this character are considered as air conditioning systems and usually employ filters and the like to take pollen and dust out of the air. Heretofore it has been the practice to determine the heat required in B. t. u. to heat the rooms of a dwelling or the like and to then determine the cubic feet per minute (c. f. m.) of heated air required for each room. With this data and the aid of suitable tables, the proper sizes of pipes for each room were chosen. While it was sometimes possible to combine several pipes together into a single pipe for a. portion of their length, it was necessary to make allowance for the air friction encountered in this combined pipe and to then make the combination pipe sufliciently large to carry the right quantity of heated air per minute. The result of this system of figuring sizes was that the combination pipes were necessarily odd sized and the hot air supply line was a tailor-made structure or fitting with the combination pipes frequently of odd and difiicult sizes.

With these difliculties in mind it is among the objects of my invention to devise a standardized combination pipe or trunk line which is applioae ble to ninety-five per cent of all heating installations and thus to obviate the expense of a tailormade system and to further avoid the unsightly jumble of pipes which ordinarily occupy valuable space in the basement and to providea heating system in which the combination or trunk line is decreased at each offshoot to thus proportion the cross-sectional area of the trunk line pipe to the cubic feet per minute of heated air to be carried.

It is a general object of my invention to provide a novel heat conducting and distributing system which divides the stream of heated air into suitably proportioned parts and conducts each part to the room, and which lends itself readily to standardization of parts.

It is another object of my. invention toprovide a more sightly and efiicient heat distributing system.

It is another object of my invention to provide a conducting means which is varied in cross-sectional area so that heated air is forced out by reason of the reduction in size of the conduit at outlet points along the conduit.

It is another object of my invention to provide a heat conducting system, the parts 91' which may be readilynested for shipment and storage.

' invention will be more apparent to those skilled Another object of my invention is to provide a i system, the parts of which are standardized to readily fit one to another and yet in which suitable subdivision of the hot air stream is secured.

Other and further features and objects of the in the art upon a consideration of the. accompanying drawing and following specification, wherein is disclosed a single exemplary embodiment of the invention, with the understanding, however, that such changes maybe made therein as fall within the scope of the appended claims, Without departing from the spirit of the invention.

In said drawing:

Figure 1 is a view in perspective of the top portion of a furnace and of a hot air conducting system constructed according to one embodiment of my invention.

Figure 2 is a view in perspective of a conduit system illustrated in Figure 1.

Figure 3 is a view in perspective of the parts shown in Figure 2 as they appear while in nested position suitable for shipment or storage, and

Figure 4 is a viewin perspective of a slip joint connection for connecting the parts of a system constructed in accordance with one embodiment of my invention.

The system I am about to describe is based on a maximum of ten 8" outlets with a total 0. f. in. capacity of 1,750 cubic feet per minute. The 80 trunk line system may use 6, 7, 8 or 9 inch outlets.

In order to better illustrate the structure and the application of my heating system to the prob-, lem of heating a building, let it be supposed that the c. f, in. requirements of a certain building have been found to be as follows: i;

Room Size 13. t. u 0. f. m Pipe size Living 20x 14 19,728 356 2 s' 40 Dining 12x 14 13,048 189 s Kitchen 10x12 9,520 124 8" 9x12 9,425 123 s" 9x12 9,425 123 8' 6x6 3,977 52 6' It is to be noted that in the example given, a total of seven pipes are required. Suppose that the grouping of pipes leaving the trunk line will be two pipes at spaced intervals, then two pipes close together, an interval, another pipe, an interval, and then two more pipes.

We find, on reference to suitable tables, that the inlet dimensions of the trunk line having ac-, commodations for seven pipes will be 23" x 10 In constructing the trunk line I may utilize a conventional furnace, indicated at It], generally, 55'

in Figure 1. The furnace is of conventional character except that the heat dome II has a single rectangular opening at the point l2 instead of a plurality of openings in the sloping side walls thereof as in the conventional furnace. A vertically disposed riser conduit I3 is positioned over the opening l2 and is held in, position by means of a rectangular upstanding flange l5 around the opening l2, the riser and dome flange being connected by means of a slip joint connection, such as illustrated in Figure 4. The riser I3 has its upper edge engaged to an elbow l6 by means of another slip-joint connection to thus change the direction of the trunk line from vertical to horizontal. 7

Now suppose that, as indicated, the first requirement of the line is one of the two supply lines for the living room. This pipe line is indicated at H, theelbow leading from the living room outlet to the pipe line is indicated at IS. The first reduction in area of the pipe line oc curs at this point since it is desirable to decrease the cross-sectional area of the trunk line to insure a portion of the heated air passing into the elbow l9 and pipe line IT. This section is indicated at 2| in Figure 2 and as has been shown the section is a substantially rectangular one except that the left side is tapered as indicated and an opening 26 is provided in this side wall. The inlet side 22 of the section 2i is the same as the outlet side of the elbow IE, but inasmuch as the reduction in size occurs at this point the outlet of section 2| as indicated at 23 is smaller, the reduction being such as to decrease the c. f. in. capacity of the trunk line by approximately the c. f. m. capacity of the pipe IT. We find by reference to suitable tables that the outlet size is 22 x 10 and this size 22 x 10 is suitable for properly supplying six remaining eight inch pipes. The next outlet which occurs is indicated at 29 and in the same manner the section 28 decreases from a size of 22x 10 to 19 x 10 at the outlet 32. Now the next requirement is for two outlet pipes, as indicated at 36 and 31. The section being necessary is indicated at 38 and is of substantially the same thickness as the preceding section but tapers on both sides, as indicated, in order to insure suitable reduction, the reduction being from 22 x 10 to 16 x 10, and leaving the trunk line of a size to accommodate a sufiicient volume of air for the three remaining pipes.

The next reduction occurs at M and is a reduction from 16 x 10 to 13 x 10. The final reduction occurs at section 46 and is a reduction from 13 x 10 to 10 x 10. This end section 46 is formed with a taper on one side or the other, as indicated at 41, and has an opening at the end thereof, as indicated at 48, for taking care of the final pipe 49.

The following is a standard table of sizes suitable for trunk lines constructed according to my invention.

Balanced trunk line Number Single outlet fitting 3;? :2 o. i. m of s" pipes 25 x 10 23 x 10 1400 s it x 10 13 x 10 700, 4

section by bellying 'out Number Double outlet fitting :2 o. r. m o; s" plp 25 X 10 1750 10 23 x 10 1575 9' 22 X 10 1400 3 19 x 10 1225 7 16 x 10 1050 6 13 x 10 875 5 10 X 10 700 4 575 3 It is apparent that by the use of these standar d sections, constructed according to my invention, a trunk line may be constructed in which the trunk line reduces in cross-sectional area wherever an outlet occurs.

The reduced sections of the trunk line may be nested one within another, as indicated at Figbellied out to permit the smaller sections to be inserted in the largerones.

In joining the sections of the trunk line I prefer to utilize a slip joint, such as indicated at Figure 4, in which the part 51 is a portion of the edge of one section and the part 52 is the adjacent edge of the succeeding section. The edge of the section 5! is turned back, as indicated at 53, while the adjacent edge 54 of the section 52 is turned back the opposite direction as indicated. A flattened member 56, having inwardly turned edges 51, may be slid on over the flanges 53 and 54 to lock the sections together and fastened by means of metal screws 60 or the like. It is apparent that modifications may be made by those skilled in the art and such modifications may be made without departing from the spirit and scope of my invention as set forth in the appended claims.

I claim as my invention:

1. In a hot air heating system including a furnace, means for conducting heated air from the furnace to various points of heat discharge in' the system comprising a single main conduit formed of a series of sections and feeder pipes leading from the sections to the points of heat discharge, the sections from which the feeder pipes lead being formed with a varying cross-sectional area, the inlet side of the sections adjacent one portion of the feeder pipe being larger in cross-sectional area than the outlet side of the tions comprising box-likemembers substantially rectangular and box-like at the inlet and at the main outlet thereof but with the main outlet reduced in cross sectional area by substantially the area of the lateral outlet, the member being tapered on at least one side thereof, and having a lateral outlet in the tapered side wall, each of said sections adapted to form a connection at its inlet end with the outlet end of the next larger section and further adapted. to nest within the larger the sides thereof.
