SAMUEL B.

RAPPLEYE, OF PHILADELPHIA, PENNSYLVANIA.

OIL-B RNER.

' Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed April 20. 1906. Serial No. 312,767.

To all whom it 'may concern:

Be it known that I, SAMUEL B. RAPPLEYE, a citizen of the United States, residing at Philadelphia., county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Oil-Burners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

The object of my invention is to produce an oil burner in which the oil, at the point of burning' is thoroughly oxygenized while avoiding the mixture, with the products of combustion, of inert gases that fail either to burn or to support combustion.

The invention also has for its object to produce a burner that is simple in construction, economical and efficient in operation, and that can be easily taken apart for cleaning.

I will now describe a preferred embodiment of my invention.

' In the drawings: The figure represents a longitudinal sectional view of my improved burner with its front end projecting beyond the wall of a combustion chamber.

The oil tube consists of a long straight section a open at the front or discharge end, and a short curved section or elbow b threaded thereto. This tube may have an internal diameter of about l l/4 inches. The closed rear end of the oil tube has an orifice communicating with a cup r.

Surrounding the oil tube is a water tube c, threaded at its rear end onto the elbow of the oil tube, and thereby at its rear end, spaced from, and held in delinite relation to, the oil tube.

e is a cup at the rear of the water tube.

The water tube may be of an internal diameter of about two inches.

An air-and-water tube, composed of a front section f, a rear section g, and a short middle T section h, extends through the oil tube along its longitudinal center, its rear end extending through an orifice in the rear end of the oil-tube. The middle section h is provided with an upright inlet tube t' extending through,

and tapped into, the section h and the walls of the oil tube and water tube. The tube t' serves to hold the air-and-water tube in iixed relation to the oil tube.

j is a cup at the upper end of tube t',

k is a cap for opening or closing the rear end of the air-and-water tube.

lwater is now dropped into the cup e.

dropped from the oil pipe into the cup r at the rear end of the oil tube. Heat is applied to the eil burner by inserting a heating medium underneath or Within the front end of the same. The cap c is turned to admit air into the air-and-water tube. The oil, after it reaches the heated portion of the oil tube` is vaporized, and the oil vapors. uniting With the oxygen of the air emerging from the air-and-Water tube, is ignited. After the tubes of the burner become highly heated, Alter the burner has become still more highly heated, the cap lc is turned to sluit off the admission of air to the rear of the air-and-water tube, and water is dropped into the cup j. The proportion of water to oil will vary with the particular application and situation of the burner, although ordinarily one part of water to live parts of oil will suffice.

The burner is especially applicable for heating boilers and hot air furnaces. the front end of the burner being inserted into the fire box so as to substantially exclude the admission of atmospheric air except such air as is admitted through the burner itself. In the drawings p represents the front wall of the fire-box. The quantity of nitrogen gas set free by combustion is thus reduced to a minimum, while the hydrogen gas is itself consumed and, with the burning constituents of the oil, produces an intense heat in the fire box.

The burner is very simple in construction, is easily operated, and may be readily taken apart for cleaning.

Having noW fully described my invention, what I claim and desire to protect by Letters Patent is:

l. An oil burner comprising an oil tube, a second tube within and surrounded by the oil tube, a third tube outside the oil tube, water receiving cups connected respectively with the second and third tubes, and means to regulate the admission of air to the second tube.

2. An oil burner comprising' an oil tube havingl a turned up rear end through which oil is supplied, an inner tube within the oil tube, the rear end of which extends through the rear wall of the oil tube, an outer' tube surrounding the horizontal part of the oil tube, means by which Water is supplied to the outer and inner tubes, and a cap on the projecting rear end of the inner tube for regulating the admission oi air thereto.

An oil burner comprising an oil tube having a turned up rear end through which oil is supplied, an inner tube within the oil tube, the rear end of which extends through the rear wall of the oil tube, an outer tube surrounding the horizontal part of the oil tube, a water receiving inlet tube communicating with the inner tube and extending through the walls of the oil tube and outer tube, and a Water-re ceiving cup on the outer tube.

4. An oil burner comprising an intermediate vaporizing tube means to admit thereto oil, an inner tube extending longitudinally Within the oil tube, an outer tube within which the inner tube extends longitudinally, means to supply water to the inner and outer tubes, and means to supply air to all the tubes.

An oil burner adapted for insertion and comprising an intermediate vaporizing admit oil to the vaporizing tube, an inner into a fire-box tube, means to tube extending longitudinally within the vaporizing tube, an outer tube within which the intermediate tube extends longitudinally, said inner and outer tubes being open to the atmosphere at points back of their exit ends, means to supply an oxygen containing iiuid to both the inner and outer tubes, whereby the oil is vaporized and oxygenized before exit from the burner and before mixture with the oxygen containing fluids emerging from the outer and inner tubes.

G. An oil burner adapted for insertion into a fire box and comprising an intermediate vaporizing tube, means to admit oil to the vaporizing tube, an inner tube extending longitudinally7 within the vaporizing tube, an outer tube Within which the intermediate tube extends longitudinally, and means to supply Water to the inner and outer tubes, all said tubes being open to the atmosphere at points back ot' their exit ends,

T. An oil burner adapted for insertion into a fire-box and comprising an intermediate vaporizing tube, means to admit oil to the vaporizing tube, an inner tube extending longitudinally within the vaporizing tube, an outer tube within which the intermediate tube extends longitudinally,

means to supply water to the inner and outer tubes, means to supply air in regulated quantities to at least one of thelast-named tubes, and'means to supply air to the oil-vaporizing tube.

8. An oil burner adapted for insertion into a fire-box. comprising an intermediate vaporizing tube having an oil inlet opening to the atmosphere, means to drip oil through tubes being open to the atmosphere at points back of their exit ends.

9. An oil burner adapted for insertion into a fire-box comprising a vaporizing tube having an inlet openingr to the atmosphere, means supplying oil through said inlet to the vaporizing tube, and two tubes extending longitudinally of the vaporizing tube and arranged concentrically with respect thereto and with respect to each other, the two last-named tubes having inlets opening to the atmosphere, and means supplying water to one or both of the two last named tubes through its said inlet.

10. An oil burner adapted for insertion into a re-b0x comprising a vaporizing tube having at one end an oil inlet opening to the atmosphere, and two tubes extending longitudinally of the vaporizing tube, one surrounding, and the other surrounded by, the vaporizing tube, each of the two last-mentioned tubes having water inlets opening to the atmosphere.

In testimony of which invention, I have hereunto set my hand, at Philadelphia, on this 17th day of April, 1906.
