CRUDE-OIL BURNER.
To all whom "it may concern:
Be it known that I, ROBERT H. Bnooxs, a citizen of the United States, residing at Huston, in the parish of Lincoln and State of Louisiana, have invented a new and useful Crude-Oil Burner, of which the follow ing is a specification.
The invention relates to improvements in crude oil burners.
The object of the present invention is to improve the construction of crude oil burners and to provide a simple, inexpensive and efficient crude oil burner designed particu larly for use in stoves for heating and cooking with crude oil, and adapted to control by means of a single valve the admission of both crude oil and air to the burner, whereby complete combustion is assured.
A further object of the invention is to provide a crude oil burner of this character adapted to be readily adjusted to secure the desired feed of fuel to produce either a slow or a fast fire.
Another object of the invention is to provide a crude oil burner adapted, when closed, to effectually prevent any leakage of oil into the stove and capable, when open, of also preventing the oil from flowing backward onto the pipes.
lVith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawing :'Figure 1 is a side elevation of a crude oil burner constructed in accordance with this invention. Fig. 2 is a longitudinal sectional view of the same on an enlarged scale. Fig. 3 is an end view of the burner. Fig. 4 is a detailed view of the plunger. Fig. 5 is an end view of the same. Fig. 6 is a detailed view of the plunger illustrating a modification of the invention. Fig. 7 is an end view of the plunger shown in Fig. 6. Fig. 8 is a transverse sectional view taken substantially 011 line 88 of Fig. 4.

responding parts in all figures of the drawing.
1 designates a barrel or casing of substantially cylindrical form provided with a longitudinal opening 2 for the reception of a valve plunger The rear end l: of the barrel or casing is externally threaded for the reception of a tubular member 5 provided with an enlarged interiorly threaded inner portion 6 which screws onto the inner or rear end of the barrel or casing. The tubular member 5 has a reduced intermediate portion provided with inner screw threads 7, which are engaged by a threaded portion 8 of the plunger 3, whereby when the plunger is rotated it will be moved inwardly or outwardly according to the direction of the rotation, to open or close the valve. The rear portion 9 of the tubular member is of a diameter slightly in excess of that of the intermediate portion of the tubular member and it is provided with exterior screw threads for the reception of a nut 10, and it operates as a metallic gland for engaging a packing 11 arranged within the nut. The nut 10 forms a stu'lling box for a stem 12 of the plunger 3. The stem, which is preferably formed integral with the plunger, is reduced in diameter and is equipped at its outer end with a hand-wheel 13, or other operating means secured by a set-screw 14L to a squared portion 15 of the stem. The outer end of the stem is reduced to provide the square portion 15 and form a shoulder against which the disk or wheel 18 abuts, as clearly illustrated in Fig. 2 of the drawing. The stufiing box operates in the usual manner to prevent any leakage at the rear end of the valve burner, and the tubular member detachably connects the plunger with the barrel or casing to enable the parts to be readily separated and assembled.
The valve casing or barrel is provided at the outer end of the opening 2 with a tapered end wall. 16 and it has a central bore, or passage, 17 extending outwardly from the opening tube through a nozzle 18 formed integral with the valve casing and tapered outwardly so as to eject or discharge the fuel in the form of a jet. The nozzle is equipped in rear of the tapered portion with a vertical flange 19, preferably formed integral with the nozzle and arranged to operate as a shield or guard to prevent any of the oil from flowing bacle ward onto the pipes with which the burner valve is connected. The flange 19 is of less diameter than the casing, and it is connected with the same by a reduced portion or neck.
The outer end 20 of the plunger is adapted to fit against the tapered wall 16 of the valve casing to close the passage of the valve burner, whereby when the plunger is screwed tightly against the end wall of the valve casing leakage of the fuel is effectually pre vented. The plunger 8 is also equipped with longitudinal passages 21 and 22, having their outer terminals arranged eccentrically with relation to the longitudinal axis of the plunger, whereby when the valve burner is closed the said passages will be located eccentrically with relation to the outer passage 18, so as to be positively closed by the end wall 16.
The passage 21, which is connected by the means hereinafter described with an oil supply pipe (not shown), is substantially V-shaped or triangular in cross section. The other longitudinal passage 22, which is connected by means hereinafter described with an air supply pipe (not shown), is slightly larger in cross section than the passage 21 to introduce a larger volume of air than oil, and it is also V-shaped or triangular in cross section. The V-shaped passage 22, which is located in the rear of the passage 21, is provided at its front end with an angularly disposed branch 28, and it is connected at a point in the rear of the inner end of the passage 21 with a circular bore 241, forming an outlet and consisting of an outer longitudinal portion and an inner angularly disposed transverse portion 25, the outer longitudinal portion of the bore or passage 24 is arranged inparallelism with the bore or passage 21, as clearly indicated in Fig. 1- of the drawing, and the transverse portion 25 is located in the rear of the said passage 21.
The inner ends of the passages 21 and 22 communicate with transversely disposed spiral grooves 26 and 27 tapered longitudinally and transversely to gradually decrease their cross-sectional area. These grooves, which are formed in the periphery of the plunger, are of the same pitch as the threads 8 of the plunger, so that the plunger may be partially rotated to carry different portions of the peripheral grooves 26 and 27 into register with the oil and air inlet apertures 28 and 29 of the barrel or casing. The barrel or casing is provided at the oil and air inlet apertures 28 and 29 with exteriorly threaded tubular extensions and 81, adapted to be connected with oil and air supply pipes. The plunger is adapted to be rotated to carry the grooves beyond the inlet apertures 28 and 29 to present solid portions of the plunger to the apertures 28 and 29 for cutting oil the supply of oil and air. The air receiving groove 27 is slightly larger than the oil receiving groove and it extends farther around the periphery of the plunger than the oil receiving groove, in order that, should there be any leakage of the oil through an imperfect fit of the parts, or an expansion of the metal, a sufficient quantity of air will be introduced into the valve casing to unite with the oil to produce complete combustion. When the ends of the spiral grooves 26 and 27 are in register with the inlet apertures 28 and 29 the maximum supply of fuel will be afforded for securing a hot, fast fire, and a gradual rotary movement of the plunger will decrease the supply of oil and air and gradually reduce the amount of fuel discharged from the nozzle, which will effect corresponding reduction in the amount of heat and produce a slow fire. The closing of the tapered end of the plunger against the tapered end of the valve casing will positively close the valve and cut off the supply of fuel to the stove.
In Figs. 6 and 7 is illustrated a modification of the invention, the plunger 82 being equipped with a single circular bore or passsage 88 which is connected by radial bores or passages 84 and 85 with peripheral air and oil receiving grooves 86 and 87, the passage 88 is arranged eccentrically with relation to the longitudinal axis of the plunger in order to enable it to be effectually closed by the wall 16 of the barrel casing.
In the form of the invention illustrated in F ig. 4C the oil and air mix in the valve casing after they leave the passages of the plunger, while in the form of the invention illustrated in Figs. 6 and 7 the oil and air mix in the longitudinal passage of the plunger.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. A burner of the class described includ ing a valve casing having oil and air inlets and provided with a nozzle, and a rotary plunger for controlling the flow of oil and air from the inlets to the nozzle, said plunger being provided with peripheral grooves tapered longitudinally, whereby upon rotation the plunger is adapted to reduce the area of the grooves at the said inlets.
