OIL BURNER Filed July 21, 1952 Patented Mar. 10, 1936 UNITED STATES PATENT Charles E. Glebe, Rankin, Tex. Application July 21, 1932, Serial No. 623,;367.

3 Claims.

The device forming the subject matter of this application is an oil burner, and one object of the invention is to provide novel means whereby the oil will be atomized before it passes to the vaporizer. Another object of thev invention is to provide novel means whereby both the atomizer and the vaporizer will be heated from the burner. A further object of the invention is to supply novel means whereby the oil or other liquid fuel i9 will be changed into gas before it is delivered to the burner.

It is within the province of the disclosure to improve generally and to enhance the utility of devices oi that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds the invention resides in the combination and arrangement of parts and in the details of constructions hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope. of what is claimed, without departing from the spirit of the invention.

In the accompanying drawing:

Fig. 1 shows in top plan, a device constructed in accordance with the invention;

Fig. 2 is a vertical section;

Fig. 3 is a side elevation showing the cap of the vaporizer;

Fig. 4 is a side elevation showing the base of the vaporizer.

The device forming the-subject matter of this application preferably is made of metal throughout. It comprises an air inlet member including a vertical tubular body 2, having a lateral air intake 3.

The numeral 4 designates a burner, which is horizontally disposed, the burner including a head 5, which, preferably, is of somewhat greater diameter than the body 2 of the air inlet member The head 5 is supported on the upper end of the body 2 of the air inlet member and has a sleeve 6 which extends downwardly into the body 2 of the air inlet member, to hold the burner 4, which is removable, in place against lateral sliding. In the upper surface of the head 5 of the burner 4 there is an outer annular groove 1, with which communicates a downwardly extended oil drain pipe 10. The head 5 of the burner is provided with an inner annular groove 8, the inner wall of which is defined by an upstanding neck 9, which extends upwardly above the remaining portions of the head 5.

The numeral ll]. designates a hollow vaporizer, including a base ll, having a concaved recess'lZ in its bottornfthe recess diately above. the neck heing disposed imme- 9 in vertically spaced relation thereto. The base ll of the vaporizer It comprises an upwardly thickened central portion it, the convexity oi which is more. pronounced than the concavity of the recess l2, so

is to be observed that the atomizer 2| is located above the grooves 8 and 1 of the burner, and the oil in the atomizer 2| is heated to a considerable degree, the oil, often, being turned partially into gas, within the atomizer 2|.

The oil, and such portions of it as may have been turned into gas, proceeds through the pipe 20 into the vaporizer Ill. The upwardly convexed portion I 4 of the base H of the vaporizer carries the oil laterally, and the oil flows out of the notches 48 of the cap I8, into the grooves 8 and 1. In the vaporizer I0, the oil is turned almost completely into gas, and burns at the notches or openings 48, air being supplied through the neck 9. If any oil, not turned into gas, is received in the grooves 8 and I, the oil, of course, burns there, and the grooves 1 and 8 are of peculiar utility for receiving a priming charge, at the starting of the burner. Owing to the great thickness of the central portion II of the base I I of the vaporizer, the base of the vaporizer will not be cooled to any appreciable extent by the air that comes upwardly through the neck 9 and is received in the recess I 2. The recess I2 serves to carry the air laterally and deliver it around the periphery of the base H, and, owing to the provision of the recess l2, the air is directed downwardly toward the grooves 8 and 1. Any surplus oil received in the groove 1, at the priming of the burner, or at any other time, is carried back by the pipe 10 to any suitable receptacle provided for that purpose. Owing to the small diameter of the pipe 10, there is not air enough in it to support combustion, and the flame does not work back, in practice, through the pipe 10 to the place where the surplus oil, if any, is stored.

Having thus described the invention, what is claimed is:

1. In a device of the class described, a vertical tubular air inlet member, a starting burner on the upper end of the air inlet member and having an upstanding tubular neck communicating with the air inlet member, the burner being provided in its upper surface with continuous inner and outer annular grooves disposed about the neck, a vaporizer located above the neck, spacing means separating the vaporizer from the neck and supporting the vaporizer on the neck, the vaporizer having outlets about its periphery and located above the inner groove, to discharge thereinto, the outer groove forming an overflow receptacle for the inner groove, a drainage outlet for the outer groove, and means for supplying fuel downwardly into the top of the vaporizer.

2. In a device of the class described, a vertical tubular air inlet member, a starting burner on the upper end of the air inlet member and having an upstanding tubular neck communicating with the air inlet member, the burner being provided in its upper surface with an annular groove disposed about the neck, a vaporizer located above the neck, spacing means separating the vaporizer from the neck and supporting the vaporizer on the neck, the vaporizer having outlets about its periphery and located above the groove, to discharge thereinto, an atomizer offset to one side of the axis of the vaporizer and located above the vaporizer, in close relation thereto, the atomizer extending across the groove from a point outwardly of the groove to a point inwardly of the outlets of the vaporizer, means for supplying fuel to the atomizer, and a conduit leading from the atomizer to the top of the vaporizer.

3. In a device of the class described, a starting burner, a vaporizer supported above the starting burner, an atomizer supported above the burner, a connection between one end of the atomizer and the vaporizer, and an oil inlet at the opposite end of the atomizer, the atomizer being provided on its bottom with upstanding ribs which are disposed transversely to the flow-line from the inlet to the connection, the connection being joined to the atomizer at a greater height than the inlet, the ribs having substantially vertical surfaces and having inclined surfaces which are presented toward the inlet, the ribs and the inclined surfaces l thereof increasing progressively in height from the inlet toward the connection, thereby forming a combined atomizing means and fuel-directing ramp.
