HEATING SYSTEM.

Application filed November 28, 1923.

My invention relates to heating systems, particularly to the type known as hot air heating systems and has for its object to provide a system whereby all of the rooms of a building may be equally as well heated regardless of the distance of the same from the furnace proper.

Another object of the invention resides in providing a system whereby the piping used in connection with the same may be so run that a minimum amount of space in the basement of the building will be utilized and so that full head room may be had throughout the entire basement.

Another object of the invention resides in providing a system in which allot the rooms of the building may be simultaneously heated without robbing any particular room so that the desired temperature may be secured and maintained in any or all rooms of the building.

In carrying out my objects I provide a looped trunk to which all the registers of the rooms are connected, which trunk is connected at both ends to the top of the furnace so that the same may be fed through both ends of the same.

Other objects of the invention reside in the detailed construction thereof as is particularly brought out in the specification and claims.

In the drawings illustrating my invention in one form Figure l is a'plan sectional view of the first floor of a dwelling illustrating the application of my invention thereto. a

In the ordinary hot air or moist air heating system in which the heated air is conducted by suitable ducts to the various rooms of the building in which the heating system is installed considerable difficulty has been found in that certain of the rooms in. the lniilding do not seem to secure suitable circulation to heat the same up to the temperature desired. This is particularly true in the ordinary system where all of the ducts leading to the various registers in the re spective rooms lead directly from a dome formed upon the top of the furnace casing. My invention overcomes these'difiiculties by providing a system whereby circulation of heated air may be secured in any and all of Serial No. 677,393,

the rooms of the building. In addition, the ordinary hot air heating system is disadvantageous in that in order to securesutllcient pitchto the hot air ducts the same are run at a steep angle, thereby reducing the head room at certain localities in the basement and so wasting space and rendering the basement less useful. In overcoming these disadvantages I utilize a looped trunk which is positioned immediately below the ceiling joists and extends in a circuitous path below the floor of the various rooms within the building, which trunk is connected at both ends and fed from the furnace proper and has suitable outlets with risers connecting with the respective registers in the various rooms to be heated.

ll or illustrating the application of my invention I have shown in the drawings a dwelling indicatedin its entirety at A which comprises a basement B and a first storv C. This building may be constructed in the usual manner having a basement floor 10 and basement walls 11 upon which are positioned floor joists 12 extending across the same and supporting a floor 13. In addition, a beam 141 is shown extending longitu dinally of thebuilding to carry the floor joists 12 near their centers and the beam is supported upon posts 15 resting upon the floor 10. In the drawings I have shown a fireplace 36 which may be provided with aflue or chimney 35 to which the furnace in my invention may be connected.

The upper story C of building A is shown as divided into a living room 15, dining room 16, kitchen 17, two bedrooms 18 and 19 and bath 20. The rooms 16, 18, 19 and 20 open intoa hall 21 positioned as shown. These rooms are formed by exterior walls 22, 23, 24 and 25 and by partitions 26, 27, 28, :29, and 31 as well as other partitions providing the necessary closets, which, how ever, donot materially enter into this invention. The construction of dwellings and other buildings being well known in the art it-has not been attempted to show the same in detail, the same'being merely illustrated in diagrammatic form to show the manner of constructing and installing my invention.

In the use of my invention I employ a furnace 32 which-may be of the ordinary construction such as utilized in hot air or moist air heating systems. This furnace is preferably of the type having a flat top 83 instead of the dome-shaped top frequently employed. 'ihis furnace is positioned toil one end or the side of the building to the chimney and is so arranged that the may he connected by a smoke pipe 34 with the chimney 35.

in the various partitions 26, 27, 28, 29, 3O

" 7 number of registers 37, :iil which are adapted to ted air into the various rooms banding as is apparent from the These tors are preferably that the Hi? are in a circui- Eelow theev registers 1 run a duct 40 which is prefer- 'ular cross section, though any oss section may be employed,

sus ended in'nnediately bejoists either in contact thereshor distance below the same,

antially horizontally throughlbt) 4 The various registers posi tioned in tl respective rooms of the dwellare comiected by means of bull-headed 44 with the trunk 43, which as is shown in the drawings is run immediately b low the same. By this means each of the respective registers is in direct communication with the said trunh so that when the heated air is conducted into the same said heated air may pass upwardly through the said ducts 44 and through the respective registers into the rooms to be heated. lhe cross sectional area of the duct 43 may be diminished between the respective registers depending upon the location of the same from the furnace 32, so that the cross sectional area of trunk 43 is in all places substantially equal to the area of all of the registers to be fed by means of the same. In other words, the cross sectional area of the duct at the portions'45 and 46 is much greater than at the opposite portion indicated at 55 as can readily be seen from Fig ure 1. p 7

As will be noted, the duct or trunk 43 is looped or circuitous in arrangement so that the portions 45 and 46 approach each other. This duct is so arranged that these ends are positioned immediately above the furnace proper.

By means of two elbows 47 and 48 this trunk may be directly connected to the top of the furnace so that the heated air formed within the same may rise to flow along the said duct and be discharged into the various rooms of the building, as required. I

F or returning the cold air from the rooms back to the furnace 3:2 I provide a number of cold air registers which are installed in the usual manner. In the drawings I have shown two cold air registers 49 and 50 which are positioned in the hall 21 and living room 15. These registers are connected by cold air pipes 51 and 52 which lead to verlength.

tical runs 53 and 54 directly connected to the lower portion of the furnace proper. It can readily be understood, however, that any number of cold air returns may be used or, if desired, the fresh air supply taken from the exterior of the building, the looseness of the windows and doors being sufficient to permit the air discharged into the rooms to escape to the exterior of the build- In installing the trunk 43 the same run immediately below the floor joists and is directly secured thereto. The said trunk is run practically horizontally throughout its length, excepting at the point where the beam 14 occurs. At this point I i the portion of said duct indicated at upwardly above the said beam running the duct between the floor and beam. Vi ith this arrangement the duct may be continuous y run close to the ceiling joists without breaking the continuity of the same. In this manner the head room in the basement is maintained uniform throughout and no space is lostdue to the arrangement of the pipes ordinarily employed and furthermore, the appearance of the basement of the building is greatly improved. The operation of the invention is as follows:

The heated air from the furnace rises to the top of the jacket of the same and into both of the elbows 47 and 48 of the trunk 43 where the same travels along the said trunk and is discharged through the various registers into the respective rooms of the dwelling. Due to the pressure caused by the heated air the same is forced along the trunlr and discharges without obstruction through the respective registers. With this arrangement, due to the positioning of all of the registers upon the single duct which is fed from both ends, all of the rooms are equally heated. This becomes evident, for if upon starting one of the registers, say register 40, should receive no heat, but heated air should be passing upwardly through register 41, this would cause a suction in the trunk 43 between the said registers 40 and 41 which would tend to draw the heated air from the furnace'32, which as soon as the same arrives at the register 40 would travel upwardly and discharge into room 18 in the desired manner. That this actually occurs must become evident when it is taken into consideration that the heated air in the duct 48 which is considerably lighter than the cold air in room 18 would be drawn toward the register 40 more readily than the cold air in room 18 would be drawn down through said register 40 to check the passage of heated air to the said register. lVhere a number of registers have been placed upon a dead ended trunk the effect of one register robbing the heat from other registers frequently occurs, but when the same are connected in a circuitous manner by a duct fed at both ends from the same heating unit, then the desired result is automatically obtained.

My invention is advantageous in that it provides a simple and eifeetive means for uniformly feeding all of the registers in a hot air system so that all of the rooms of the building to be heated can be maintained at the desired temperatures. At the same time, an inexpensive and economical construction is provided whereby the registers are fed by a single circuitous trunk which nay be positioned close to the floor joists of the dwelling so that suitable head room is maintained throughout the entire basement and so that no space is wasted due to pipes extending across the same.

In accordance with the patent statutes I have described my invention, illustrating the best embodiment thereof, but I desire to have it understood that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.

I claim:

1. In combination with the rooms of a dwelling, a number of registers positioned therein arranged in a circuitous path, a

looped trunk having separated ends connecting and feeding all of said registers and a heating plant for simultaneously feeding said looped trunk with heated air at both separated ends thereof, whereby a uniform and balanced distribution of heated air is secured to all of said rooms.

2. A heating system comprising a heating plant, a looped duct having the ends thereof connected to said heating plant, registers connected with said duct at intervals along the same, all of said registers being fed thereby so that heated air may travel in either direction along portions of the duct in order to insure uniform distribution of the heated air to the registers.

8. A heating system comprising a heating plant, a looped duct connected therewith, and fed from both ends thereof, registers positioned at intervals along said duct, and all of said registers being fed with heated air from said duct, said duct diminishing in cross sectional area by substantially the cross sectional area of each register that is fed thereby, as said register is distant from the heating plant, whereby a uniform distribution of heated air is provided for all of said registers.
