3 Claims.

The invention relates to a combination heating and cooling unit.

The primary object ofV the invention is the provision of a unit of this character, wherein l the heated air will be properly humidied for the purpose of heating a room or rooms of a building and particularly where such building lacks a cellar or a furnace room, the unit being of novel construction and is readily convertible for cooling purposes.

Another object of the invention is the proviv sion of a unit of this character, wherein the same is susceptible of being suspended from the floor within a building for installation where such building lacks a cellar or basement or what is more commonly known as a furnace room and the unit when operating functions as a heater as well as a cooling unit. The air heated is susceptible of treatment to eliminate dryness so that the heated air will be thoroughly humidiied and the heating of the building or room being successfully carried forth without regard to the size of the same.

A further object of the invention is the provision of a unit of this character, which is comparatively simple in its construction, thoroughly reliable and effective in its operation, enabling th'e installation economically, durable, affording a combination heater and cooler and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1 is a top plan view partly in section o of a heater constructed in accordance with the invention.

Figure 2 is a section'al view on the line 2--2 of Figure 1.

Figure 3 is a sectional view on the line 3-3 of Figure 2.

Figure 4 is a sectional of Figure 2.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

view on the line 4 4 Referring to the drawings in detail, A desig-v sufciently for the installation of a. heating and cooling unit constructed in accordance with the invention and hereinafter fully described.

The unit constituting the present invention comprises a substantially rectangular shaped body I 0 preferably made from sheet metal and has interiorly thereof I I having common thereto The body I0 at its top is ginal 1atera1 iiange I3 face ofthe iioor A at portion for said unit so the separated twin fire boxes a hood formation I2. formed with a inarcounterseated in the top opening or cut away that it will be suspended beneath said floor in operative position.

The iire boxes II are spaced from each other and about the hood I2 is a heat distributing wall I4 preferably made from insulating material and providing between it and the hood an air outlet space or chamber I5 for directing air heated in an upward direction through a register plate I6 carried at the top of the unit.

The fire boxes II at the upper portion of the hood have communication with circuitous flues I 1, these being located between the boxes and open into an outlet nipple or opening I8 to a discharge chimney or iiue so that the spent products of combustion will be thereto.

delivered from the unit Between the body I 0 and the wall I4 is an air inlet chamber or space I9 leading to a downwardly tapered lower end portion 20 built with the said unit, the

air being admitted in a downward direction through the register plate I6 to the chamber or space I9 for the heating thereof Within the body I IJ. The wall I4 is continued into the lower portion 20 and inwardly angled at 2| which angled portion is provided with louvered openings 22 communicative with fan chambers 23, these being i cross webs 23" separated by partitions 23 and respectively.

In each of the' chambers 23 is arranged an electric fan 24 the electric circuit thereof being switch 25. 'I'he fan is operated the unit is utilized as a cooling controlled by a for cooling when unit.

Located within each lire box II is a gas burner 26, its feed pipe 27 being tted with a valve 28 controlled by a turn key 29 accessible at the top of the unit for regulating or shutting off the supply through the pipe 21 to the burner 26. Co-,

active with the burner 26 equipped with a valve 3|.

spray tube 32, its water It is preferable to have is a lighting pilot 3o` 34 and this tube 32 the chamber I9 enheated air.

the hood I2 formedl with peep openings te.; these covered by heat resisting transparent panels 3 which are remov1 able to permit convenient lighting of the pilots d@ associated with both burners 26.

The hopper portions 2t have leading therefrom at the lowermost points thereof drain pipes 3l! for the discharge of the water from the tube 32.

In the suspended position of the unit from the oor A the heated air will be delivered through the register plate te interiorly of a room or buildi-A ing and such heated air is humidied, the burners 2d heating the air.

When it is desired to use the unit as an-air conditioning or cooling unit the fans ,2d are started so that this air under the force of the fan will be circulated through the register plate i@ into the room or building. This circulated air will be water sprayed for air .cooling effect.

The circuitous lues deliver the spent products of combustion within the re boxes to the opening'.

i8 which is locatedfat the transverse center of the body of the unit and intermediate of thenre boxes interiorly thereof.

The iire boxes, have the lateral housing-s 3d,

these opening through, opposite ends of the body as will be apparent from Figure y2A of the drawings...

nre boxes and spaced from the vcasing and also 1 said fli'e boxes to effect air inlet andv outlet spaces through said grated top, the wall being extended into the tapered lower end of said casing and inwardly angled at its lower portion, the angled.

areas 'of said wall being formed withA windows partitions and webbings arranged within the said wall and constituting therewith fan chambers beneaththe fire boxes, fans operating within.a said chambers, the louvered windows establish- I ing communication between the chambers and the aifinlet-space, a waterspray located in theair in lctspace between the casing and said wall, and lateral housingsformed with the fire boxes and opening reversely to each other through aoraass opposite sidesof said casing and carriedthrough said wall. f

2. A unit of the character described comprising a casing having a grated top and a downwardly 'tapered lower end, separated twin re boxes interiorly of said casing, a wall about said re boxes and spaced from the casing and also said nre boxes .to effect air inlet and outlet spaces through said grated top, the wall being extended into the tapered lower end of said casing and inwardly angled at its lower portion, the angled areas of said wall being formed with windows, partitions and webbings arranged within the said wall and constituting therewith fan chambers beneath the rire boxes, fans operating within saidchambers, the ioiivered windows establishing communication between the chambers and the airf. inlet space, a water spray located in the air v,inlet space between-'the casing and said wall, lateral housings formed with the re boxes and opening reversely to each other through opposite sides of said casing and carried through said wall, anda h ood common to there boxes and establishing 4cornrnuini cation therebetween.

i 3. A unit of the character described comprising a casing having a grated top and a downwardly taperedlower end, separated twin re boxes interiorly of said'casing, a wall about said re boxes andspaced from the casing and also said fire boxesf-to edect air inlet and outlet spaces throughsaid grated top, the wall being extended into the tapered lower end of said casing and inwardlyv angled at `.its lower portion, the angled l areas of said wall being formedwith windows, partitions and webbings arranged within the said wall and constituting therewith fan chambers beneath the nre boxes, fans operating within said chambers; the louvered -windows establishing communication between the chambers and the air inlet space, a water spray located in the air inletspace between.. the casing and said wall, lateral housings formed with the fire boxes and opening reversely to each other through opposite sides of said casing and carried through said Wal1,a hood commento the lire boxes and establishing. communication therebetween, and burners arranged within said housings for eiecting com- -bustion in said fire boxes and accessible through the open.y ends of said housings.
