Application filed January 6, 1919. Serial No. 269,853.

To all whom it may concern:

Be it known that I, DAVID J. NYsEwANDER, a citizen of the United States, residing at Toledo, in the county of Lucas and State of i0, have invented certain new and useful Improvements in Heaters, of which the following is a specification.

The object of this invention is to provide inexpensive means whereby an apartment or building may be efiectively and economically heated. The invention seeks to provide an apparatus for the stated purpose which will be simple in its construction and compact in the arrangement of its parts and by which a thorough circulation of heated air will be set up so that all parts ofthe apartment or building will be kept at the desired temperature.

The invention is illustrated in the accompanying drawings and consists primarily in mounting a radiator concentrically within an upright tubular drum, placing burners within the radiator near its lower portion, forming a water jacket in the wall of the radiator around said burners so as to protect the drum from excessive heat by inclosing the burners in a fire chamber, and providing access to said chamber through opposite doors in the drum and in the wall or" the jacket; and the invention further consists in certain novel features which will be hereinafter first fully described and then more particularly pointed out in the appended claim.

In the said drawin s:

Figure 1 is a vertical section of a heater constructed in accordance with my invention;

Fig. 2 is an elevation of the same;

3 is a horizontal section on the line 3-3 of Fig. 1.

In carrying out my invention, I employ a cylinder or drum 1 which has its upper and lower ends open and is preferably construct ed of sheet metal so that it will be light and inexpensive. This drum is supported upon. feet 2 so that an open space will be provided between the floor or other fixed support and the lower end of the drum through which cold air may readily pass into the drum, the air being heated as it rises through the drum and escaping through the upper end thereof to circulate through the room or building. Housed within the drum and supported in spaced relation thereto by brackets 3 is an inner casing or radiator consisting of a lower cylinder slightly tapered and the closed as shown. This inner drum or-radiator will also be preferably constructed of sheet metal and the lower portion thereof constituting the fire chamber will preferably be constructed with double walls, as shown at 8, whereby it may be utilized as a water jacket so that water may be heated for domestic use and also for supplementing the hot air circulation as a medium for heating the building or room. IVater may be supplied to this acket through any convenient means and I have illustrated portions of a feed or inlet pipe 9 and an outlet or circulating pipe 10 passing through the drum 1 and having their ends secured in the water jacket so that the desired circulation of water will be set up. These pipes also serve as supports for the radiator or inner drum so that the same will be maintained in its proper position relative to the outer drum or casing. Near the lower closed end of the radiator I provide a plurality of openings 11, and on the inner side of the radiator I provide an annular damper 12 which is provided with a similar series of openings 13 adapted to register with the openings 11 to admit air to the interior of the radiator or to be moved so that the spaces between the said openings 13 will cover the openings 11 and thereby cut-off the inflow of ,air. This annular damper may be maintained in proper position within the radiator by any convenient means and I have illustrated overhanging lugs 14 secured on the inner surface of the radiator and engaging over the upper edge of the damper, a handle 15 extending through a slot in the radiator being provided for the manipulation of the damper. It will be readily understood that by properly adjusting this damper the inflow of air to the fire chamber of the radiator may be regulated so that combustion will be properly supported and a circulation through the radiator established to carry oli obnoxious fumes and gases. To provide for the outlet of the said fumes and gases, a flue 16 is fitted through the upper portions of the radiator and the drum and has its inner end turned upwardly within the radiator, as shown at 17 so that the gases and fumes will be drawn into the flue from the top of the radiator and thence carried out to the chimney. A check damper 18 may be provided in the flue as will be readily understood. It is intended to employ either gas or oil as the fuel in my heater and for this burner 19 which is preferably in the form of a ring having jets on its inner periphery, said ring being disposed immediately below the water jacket 8 and being supplied through a gas pipe 20 leading through the walls of the drum and the radiator from any source of. supply; I also provide a vapor burner 21 which is disposed preferably at the axial center of the water jacket and may be supported by the gas burner. This vapor.

burner may be of any well-known construction and is fed by a supply pipe 22 fitted with a regulating valve 23 and connected to a pipe or tube 24: leading from a supply tank which may be located at any desired point and also connected with a source of compressed air so that the oil passing to the burner will be in proper condition for rapid and thorough vaporization. To permit access to the burners for inspection and cleaning of the same as may be needed, I provide a-door 25 in the drum and a similar'door 26 through the jacket of the radiator opposite the first door. i

It is thought the operation of the heater will be readily understood. The water pipes 9 and 10 may be connected with a boiler and also connected with a system of radiators and with asource of water supply so that hot water may be had at such points as may be needed or desired. The water, of course, will fill the jacket 8 and the entire system of radiators including the circulating pipes and the boiler. Ignition is effected in the usual manner, the gas burner being preferably lighted first and permitted to heat the vapor burner and the latter then being lighted. from said gas burner. The heat from either or both burners will rise within the fire chamber of the radiator and will play directly on the water jacket so thatthe drum opposite said jacket'will be to an extent protected. The entire surface of the radiator will be quickly raised in temperature and will radiate heat. The heat ra diated from the upper portion of the radiator and the outer surface of the water jacket will act directly upon the air. within the drum so that said air will be raised in tem perature and will flow from the top of the drum into the room andthrough the building thereby setting up a circulation which .will draw cold air in through the lower end of the drum to be in turn heated and escape through the upper end thereof. The gases and fumes rising from the burner will pass to the top of the radiator and will be then turned back toward the open upturned end of the escape flue and will enter said flue and thence pass out through the chimney, the

flow of said gases and fumes being regulated by the manipulation of the check valve purpose I provide a gas and set up a circulation through the pipes 9 and 10 toestablish a supply of water'in the boiler and in the radiators connected with said pipes.

The tapered form of the upper portion of the radiator will bring the walls of the same across the direct path of the ascending heated currents so that they will play directly upon the entire surface and upon the top closed end of the said tapered portion and, consequently, a large active radiating surface will be utilized so that the air contained between the radiator and the drum will be very quickly brought to the desired temperature. The several parts are very simple in their construction and are compactly arranged so that the heater will occupy very little space and will utilize all the heat generated without any appreciable waste of the same and consequently a low grade of fuel may be employed and the cost of maintenance minimized. As the lower end of the radiator is closed the inflow of air will be reduced so that the draft through the radiator will not be strong enough to carry the heated currents rapidly and directly into the flue before they have had time to do the expected work while at the same time sufficient air will be admitted to maintain the combustion and establish the necessary circulation. Moreover, should some oil overflow when the initial combustion is set up in the use of the vapor burner the overflow will be caught by the closed.

lower end of the radiator and thereby prevented from running over the floor of the room and damaging the same.

Having thus described the what is claimed as new is:

In a heater of the type described, the combination with an upright drum open at its ends, a door in its wall, a radiator supported concentrically within the drum and having a tubular lower portion and a tapered upper portion closed at its upper end, a water jacket in the wall of the tubular portion surrounding an internal fire chamber, and a door through the jacket opposite the other door; of a damper controlling the admission of air into the lower end of the radiator, an escape flue leading from its upper portion, a vapor burner disposed within and near the center of said fire chamber, a gas burner also disposed within said. firechamber at the bottom of the jacket, and means for supplying appropriate fluid fuel to said burners selectively.

In testimony whereof I afliX my signature.

invention DAVID J. NYSEWANDER. [L. 8.]
