HEATING APPARATUS.

Application filed April is, 1922. Serial No. 554,979.

To all whom it may concern:

Be it known that 1, Common W. SnxToN, a citizen of the United States, residing at Charlotte, in the county of' Mecklenberg and State of North Carolina, have invented new and useful Improvementsin Heating Apparatus, of which the following is a speci-' fication.

This invention relates to heating apparatus for buildings and proposes the construction of a heater of the heated air type which is adapted to be installed on the same fioor or level as the rooms to be heated and will positively create and maintain circulation of air by drawing cold air from a remote point in the room which is to be heated,

or from another room or rooms, through a properly proportioned conduit, and radiatmg warm air to be carried by convection to the point or points from which the cold air is exhausted.

ber by being provided with a plurality of air fines communicating at their opposite ends with the air space between the double walls at the top and bottom of the heater and the front portion of which includes a' fire pot of substantially the same width as the combustion box and being unrestrictedly open at the top and in communication with said flue chamber.

Still another object of the invention is the provision of a transverse partition wall lying in a vertical plane at an intermediate portion of the flue chamber and provided with a permanentlyopen avenue of communication below its lower edge between the adjacent parts of said flue chamber, and a damper-controlled opening near its upper end, the smoke pipe being'located on the opposite side of'said partition wall from the fire pot.

Still another object of the invention is the provision of the double walled air chamber surrounding the combustion box, and having cold air conduits leading from remote points to the lower portien thereof and also having perforations in its upper wall communicating with the atmospher nfhereby air is supplied to said air chamber to be heated therein, and discharged therefrom.

Still another object of the invention is the provision of a humidifier in the heated air chamber, equipped with signalling means for indicating the level of liquid within said humidifier. v

ll ith the above and other objects in view, my invention consists in the improved heat ing apparatus illustrated in the accompanying drawings, described in the following specification, and particularly claimed, and in such-variations and modifications thereof as will be obvious to those skilled in the are to which my invention relates.

In the drawings accompanying and forminga part of this specification, and wherein the preferred embodiment of my invention is illustrated:

Figure 1 is a side elevation in cross section showing the construction of my improved heating apparatus.

spectively, the front and back outer Walls of the heating apparatus which are joined to the outer side walls 3 and 4:, the shape of the outer casing thus formed being rectangular. These walls are preferably made of a heavy grade of sheet metal and are secured to the bottom and top walls 5and 6, respectively. This casing surrounds an inner casing or combustion box which is likewise formed of four vertical side walls '7, 8, 9 and 10 which are joined at the top and bottom to the

headers

11 and 12, and held in place by the stay bolts 56. The combus- Referring now in detail to the several figures, the

tion box is spaced from the outer casing on all sides, being supported from the bottom thereof upon the upwardly extending

lugs

13 and 14 which are preferably made integral with the outer bottom wall 5. The

front walls 1 and 7 of the outer casing and combustion box are perforated with aligned rectangular openings in which is seated the frame 15 of the fuel door 16 hinged at its lower edge 52, and with another pair of The walls 1 and 7 are also proyided"with elongated aligning apertures which .are

By the arrangement and construction of my improved heating apparatus I have perfected a heating device in which uniform distribution of heat is assured by blanketing the entire surface of the heater with a layer of flowing air so that the heat is not all radiated at one spot in the vicinity of the heater but is absorbed by the flowing medium and distributed by convection to the parts from which the cold air is withdrawn. By providing the fire pot with an outlet-opening of unrestricted area the products of combustion are permitted to issue freely therefrom and to play with full intensity upon the tubular fines, and the absence of curves and inaccessible recesses on the floor of the combustion box makes it possible to easily and completely remove soot from said combustion box by way of the clean-out door. The blanket of air surrounding the combustion box acts as a heat insulation, making it perfectly safe to install the heater adja cent walls and floors of a non-fireproof na-V heaters of the usual type has heretofore usually been neglected on account of its in accessibihty.

Having described my invention what I claim as new and desire to secure by Letters Patent, is v A heater comprising an outer casing, a combustion box within said casing and spaced from the walls thereof forming an enveloping air chamber, an open topped fire pot in the forward part of said combustion box, a plurality of banks of vertical fiues arranged rearwardly of said fire pot and communicating at their opposite ends with said enveloping air chamber, a smoke pipe leading from the rear part of said combustion box, a vertical partition arranged intermediate said banks of fines and between said fire pot and smoke pipe for deflecting the heated products of combustion longitudinally of said fines, said partition having a damper controlled draft opening at its upper end, a grating constituting the upper wall of said air chamber and extending above said fire pot and said flues and cold air supply conduits communicating with that part of said enveloping air chamber which lies directly beneath said banks of fiuesl In testimony whereof I have hereunto set my hand in presence of two subscribing wit- IQQSSGS.
