"CURTIS C. LILLIBRIDGE, OF HUTCHINSON, KANSAS.

. OIL-BURNER.

Specification of Letters Patent. Patent d Get. 16, 1917.

Application filed February 8, 1917. Serial No. 147,422.

To all whom it may concern Be it known that I, CURTIS C. LILLIBRIDGE, residing at Hutchinson, in the county of Reno and State of Kansas, have invented certain new and useful Improvements in Oil-Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in liquid fuel burners, the principal object being to provide means whereby the flow of fuel may be automatically cut 011 in case more oil is running into the burner than can be consumed.-

An additional object is to provideaburner in which the flow of fuel to the same is stopped by means controlled by the excess fuel.

With these and other objects in view, the invention resides in the novel features; of construction, combination, and arrangement of parts which will be hereinafter more parti-cularly described. and claimed.

In the accompanying drawing:

Figure 1 is a side elevation of a liquid fuel burner provided with my invention, the supplemental valve'thereof being in open position;

Fig. 2- is a similar view with disposed so that the valve will be closed;

Fig. 3 is a horizontal section taken substantially on the plane of the line 3-3 of Fig. 1; and

Fig. 4 is a detail the burner proper.

The invention is shown applied to an or dinary form of liquid fuel burner, but it is obvious that with'slight modifications it may be used in connection with any preferred form of burner using coal oil or other liquid fuel. The burner proper l is a tank (not shown) by the supply pipe2, the same having the usual control valve 3 and a supplemental cut 03 valve 4, the first being preferably positioned outside of the stove so that it may be manually manipulated, while the supplemental valve is placed inside of the stove and beneath the burner to allow it to be automatically operated as will be hereinafter explained. I

The burner 1 has the usual flame spreader 5 and an annular oil groove 6 into which the parts sectional view through the oil flows from the supply pipe 2 before .being ignited, ,said groove being disposed in .the groove 6, thus only a certain amount of oil may collect in the bottom of the burner,

the excess flowing down the overflow pipe 8.

The lower end of the overflow pipe, which may be of any desired length, is placed above a receptacle 10 which will receive the excess oil and prevent the same from being wasted. This receptacle 10 forms one portion of the means for automatically controlling the supplemental cut off valve {1, the other part consisting of a cylindrical tubular member 11, the same being approximately six inches long and one inch in diamcter. This member 11 is secured to the handle of the valve 4, which in the present instance is a hand wheel 12, by the clips 13 which surround the member and have clamping ears 14 to engage the spokes of. the hand wheel. It will be noted that the clips are preferably disposed around the member 1 nearer one end than the other, said member thereby forming in effect a lever arm.

The. short end of the member 11 is provided with a hook 15 on which the handle of the receptacle 10 is hung. The weight of the empty receptacle is overbalanced by a meal ball 16 placed within the tubular member 11,-and when thisball is at the end of the member opposite to that carrying the hook 15, the parts will be disposed as shown in Fig. 1 and the supplemental valve 4 will be opened. As soon, however, as the weight of the receptacle 10 and its contents equals or slightly exceeds the weight of the ball 16, the same will be moved to the opposite end of the member as illustrated in Fig. 2, whereupon the valve will be closed. In this manner any oil which is not ignited in the burner will flow down the pipe 8 and be collected in the receptacle 10. This overflow of fuel is generally caused by the flame of the burner being accidentally blown out, and

unlessthe usual valve 3 is manually cut oi the .oil will. continue touflow. and A will thus be wasted. My invention overcomes this difficulty by automatically stopping the flow of fuel and also providesmeans for collecting the liquid which would ordinarily be wasted.

I claimz. I v y 1. The combination with a burner, a fuel supply pipe connected therewith, a cut off valve in said supply pipe, an arm fixedly secured to said valve, overbalancing means movable on said arm, and means carried by said arm for collecting any excess fluid delivered to the burner for shifting said overbalancing means from one end of the-arm to the other to operate said valve.

2. The combination with a burner, a fuel supply pipe connected therewith, a cutoff valve in said supply pipe, an arin secured to the handle of said valve and comprising a cylindrical tubular member, an ove'rbalanc ing ball movable to either end of said memher,

a hook on one end of said member, an.

overflow receptacle carriea by said book, an

and into said receptacle,

I overflow pipe extendingjrom, said burner said ball being movable past the center of said. tubularmeinber when a duantityof liquid has flowed into said receptacle, whereby to automatically close the valve. 1 v v In a device of the class described, a burner having an annular oil groove, a fuel supply pipe connected with said burner, a out off: valve in said supply pipe, an overflow pipe having one end extending slightly above the bottom of said oil groove, a cap spaced above said end of the overflow pipe, and an overbalancing means connecting the other end f the overflow pipe with said out off valve. y

In testimony whereof I have hereunto set w my hand in the presence of two subscribing witnesses. 7 v y y d CURTIS O. LILLIBRIDGE.
