HEATING APPARATUS.

Specification of Letters Patent.

Patented May 4, 1920.

Application filed April 6, 1918 Serial No. 221L081.

To all whom it may concern:

Be it known that I, JoHN RYcKMAN, a citizen of the United States residing at Minneapolis, in the county of l lennepin and State of Minnesota, have invented certain new and useful Improvements in Heating Apparatus, of which the following is a specification.

My invention relates to heating apparatus and the object is to provide 'a system in which a circulation of hot water or steam for heating purposes may be obtained by-the combustion of fuel oil in an efficient and economical manner.

The full objects and advantages of my invention will. appear in connection with the detailed description thereof and are-particularly pointed out in the claims.

Referring to the drawings which illustrate the application of my invention in one form,-

Figure 1 is a diagrammatic view, largely in vertical section, of my apparatus. Fig. 2

is a view in section on line 22 of Fi 1.

Referring to the drawings, 10 in( icates the water jacket of the boiler having the inner cylindrical wall 12 and the outer cylindrical wall 14, these two walls being joined at their ends to form an annular chamber for containing .water. Leading from the top of the water jacket thus formed is the outlet pipe 16 while a return pipe 18 enters the bottom of the water jacket. Inclosing thewater jacket is the drum 20, preferably of sheet metal, from the upper end of which is led the escape flue 22 for spent ases. The rear end of the drum extends yond the water jacket to form a passageway 24 and the drum is positioned eccentrically around the water jacket with their lower surfaces in contact so as to form the passageway 26 at the top. The boiler formed by this constructionmay be supported on suitable legs 28 connected by cross bars 30. The front end of the drum fits closely upon the front end of the water jacket and is provided with a clean out door 32 above the water jacket and the opening 34 leadin to the space within the inner wall 12 of t e water jacket. A tube 36 having a burner tip 38 extends through the opening 34 for a short distance and beyond the burner tip is a deflector 40. The pipe 36 leads from a fuel oil tank 42, and

within the tank the pipe is bent to form two vertical portions 44 and 46 connected by a short bend at their lower ends. The portion 44 is closed at its top and at a short distance below the top is provided with an opening 48 for entrance of the compressed alr, while in the bottom of the portion 46 is a small opening 50 for entrance of fuel oil. The valve 52 controls theflow through the pipe 36. The tank 42 is provided with a cook 54 which is ordinarily closed but which may be opened to determine the upper level of the fuel oil in the tank when the oil is supplied by opening the valve 56 in the supply ipe 58. The space in the tank 42 above t e oil level is supplied with compressed air from a storage tank 60 connected with the top of tank 42 by a pipe 62 provided with an air vregulator 64 and a pressure gage 66. The storage tank is connected by a pipe 68 with an air compressor 70. The ipe 68 is provided with a pressure gage 2 and with an automatic electric regulator 74 of well known construction. An electric motor 76 is geared to the air compressor and a supply of current to the motor is switched on and off by the regulator according to the air pressure in the pipe 68.

he advantages and operation of my invention will be apparent from the foregoing description. A substantially constant air pressure is maintainedv in the compressed air storage tank and pressure therefrom reduced, as desired, by the air regulator 64 is transmitted to the space at the top of the fuel oil reservoir. Notwithstandin slight fluctuations in the air pressure in t e storage tank, it will be apparent that a constant pressure will be maintained in the tank 14. Compressed air enters the opening 48 and flows through the pipe 36 to the burner in its passage drawing in fuel oil in small uantities through the small opening 50. ir and oil are delivered from the burner tip in the form of a fine mist or spray which burns with intense heat in the space within the inner wall of the water jacket, the buming gases being deflected against the inner wall 12 by the deflector and passing back over th outer wall 14 to the escape flue 22. The wager in the water jacket will be quickly heated and cause a circulation of hot water out through the pipe 16 and returning on said air tank,a burner and means for delivering oil and air from said oil tank throughsaid burner in the form of mist.

2. A heating apparatus comprising a burner, a fuel oil tank, a compressed ir tank, a pi e connecting said air tank to t e top of sai oil tank, a U-sha ed pipe in said -oil tank, one of the brane es of said U- shaped pipe being closed at its top except" for a small air inlet opening, the other branch of said-U-shaped pipe having a small oil'inlet near its bottom and having its upper end connected to said burner for delivering oil and air from said oil tank through said burner in the form of mist.

In testimony whereof I hereunto aflix my signature.

JOHN RYOKMAN.
