CRUDE-OIL BURNER.

Specification of Letters Patent.

Patented Sept. 20, 1910.

Application filed December 13, 1909. Serial No. 532,794.

To all whom it may concern:

Be it known that we, l/VILLIAM L. LUB

BOOK, residing at Houston, in the county of Harris and State of Texas, and SAMUEL HAMBLEN, residing at Poi-tales, in the county of Roosevelt and Territory of New Mexico, have invented certain new and useful Improvements in Crude-Oil Burners, of which the following is a specification.

Our invention is in the nature of an improved portable crude oil burner, more particularly adapted for burning crude oil; and it primarily has for its purpose to provide a burner of this character, of a very simple and inexpensive nature, easily manipulated, and absolutely safe in its operation.

In its generic nature, our invention embodies a novel construction of burner, applicable to any ordinary cooking or heating stove or fire-place, and it includes a novel cooperative arrangement of parts, whereby, in its operation, it will burn the gas or vapor from the oil only, and does not consume the oil until it is transformed into vapor.

In its more subordinate features our invention consists in certain novel arrangement and peculiar combination of parts, all of which will be hereinafter fully described and specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which- 'Figure 1, is a view illustrating our improved burner as in use on an ordinary cooking stove. Fig. 2, is a vertical section thereof. Fig. 3, is a detail perspective view of the base portion of the burner. Fig. 4, is a similar view of the burner end. Fig. 5, is a detail view of the cup or batlle member, hereinafter specifically referred to. Fig. 6, is a perspective view of a modified form of our improved burner. Fig. 7 is a vertical section of the form shown in F i 6. Figs. 8 and 9, are diagrams hereinafter specifically referred to.

Referring now to the accompanying drawings in which like numerals and letters designate like arts in all of the figures, 1 denotes a cast lIOIl cylindrical base having a vertical flange 1 and a hub portion 1, having a central aperture 1. The hub portion 1 has its upper end formed with a circular horizontal enlargement 1 the upper face of which is convexed, as shown by 1", the reason for which will hereinafter be explained. The body 1 is also provided with a suitable number of integral legs 1", for conveniently restin the burner on the stove or fire-place, an also to provide a suflicient space below the body 1 for 0011- veniently attaching the feed pipe 2, which is provided with a regulating valve 2, as clearly shown in Fig. 1; and the said pipe 2, in practice, is joined with any suitable source of supply.

A supplemental feed pipe section 3 joins with the pipe 2 and the said pipe 3 is of a diameter to pass freely up through the bore of the hub l", of the base, and in practice, the upper end of the said pipe 3 is projected above the convexed surface of the hub of the member 1, and the said projecting portion is formed with an external thread 3, as shown.

t designates a cast iron body having an internally threaded socket 1 to engage the threaded end of the pipe 3, and the lower face of the said member 4 is concaved as at 4 to snugly seat against the convexed face of the hub member 1. The body 4 is also provided with a jet opening 49 that communicates with the socket 4i and the pipe 3, and discharges into a bowl surface 4: on its upper end, which upper end is in the nature of a vertical extension rim 4; having a downwardly beveled surface 4., as shown in Fig. 2.

(3 designates a cap or ballle member having an inverted cup shape, and of a diameter slightly in excess of the extension 4L, of the member 4, whereby an annular jet or cscape channel 5 is provided between the members 6 and 4, and the bottom of the annular portion or rim (3 is beveled on a plane with the beveled surface 1 of the member to rest on said surface. The cap member 6 has a suitable handle portion 6".

From the foregoing description taken in connection with the accompanying drawings the ad vantages of our invention will be apparent to those skilled in the art to which it appertains.

The oil as it comes up through the feed pipe 3 discharges through the jet aperture 4 of the member 4, into the bowl end 1 thereof, which forms an oil receiving cup. As soon as the member 4 and the member 6 are properly heated, the oil, as it passes into the space under the cap (5, boils and generates gas and escapes through the jet orifices 6 or as the case may be, where it mixes with air and burns with a blue flame. Should the oil in the cup 1 overflow and run out through the openings 6 (m the forms shown in Figs. 1, 2 and 3 of the drawings), the drippings will fall on the surface 1 of the base, which being hot will cause the drippings to splatter and become ignited, thus the overflow or drippings of the oil will be consumed before they reach the bottom 1 of the burner. In the forms shown in Figs. 6 and 7, however, the drippings from the apertures 6O" will fall directly into the base member 1 In Figs. 6 and 7 is illustrated a modlfied form of our improved type of burner which embodies the same generic features as shown in Figs. 1 and 3. In this form the rim or disk 40 is of considerably larger diameter than the disk 4 shown in Fig. 2, and it is made convexed and formed with a series of ridges 40 that act as rii'fles or retarding means to keep the oil that drips over from the bowl 4 from flowing quickly toward the outer edge or rim of the disk 10 By having the disk 40 large and ridged, as shown in Figs. 6 and 7, the oil is retained longer on the disk, and a greater quantity can constantly be vaporized than is possible in the form shown in Figs. 1 and 2, and the cap plate in the modified form, designated by 60, is made dome shaped with lts base of a diameter substantially that of the disk 40 and provided with jet outlets 60 as shown. The increased size of the cap 60 also providing a large heating surface for facilitating the vaporization of the oil. In the form shown in Figs. 6 and 7, the circular en largement 1 shown in Figs. 1 and 2 is not required.

In the practical construction our improved burner may be constructed, as shown in Figs. 1 to 6, rectangular or elongated, as diagrammatically represented in Figs. 8 and 9, or any other desired shape, and of any material adapted for the purpose, the exact shape depending largely upon the practical purpose for which it may be used, as the same can be readily applied to any cooking or heating stove, fireplace, green houses or hot house, with or without legs, as described.

What We claim is:

1. A crude oil burner comprising a base having a vertical annular flange and a centrally apertured hub portion, said hub portion having a circular horizontal enlargement, said enlargement being convex on its upper face, a member having an aperture therethrough, and an internally threaded socket in its lower end, said member being adapted to seat upon the convex face of the enlargement of the hub portion, and a cap adapted to seat upon the upper portion of the said member, substantially as shown and described.

outwardly and downwardly inclined face of the hub enlargement being of a greater diameter than the aforesaid chamber Whereby the unconsumed drippin'gs from the said chamber will be received thereon, for the purposes described.

3. In a crude oil burner, a base having an annular vertical flange, and a centrally apertured hub portion, a member having a central aperture adapted to rest upon the upper face of the hub portion, said member having an internally threaded socket in its lower end, a feed pipe having an externally threaded portion adapted to fit within the internally threaded socket of the said member, said member also having its upper end formed with a concaved depression, and a cap member adapted to seat upon said member over the concaved portion thereof, said cap member having discharge outlets, substantially as shown.

4. In a crude oil burner, a base having an annular Vertical flange, and a central hub portion, said hub portion being centrally apertured and having an enlarged circular portion at its upper end, said enlarged circular portion being convexed on its upper face, a member concaved on its upper and lower ends and adapted to seat upon the horizontal enlargement of the hub portion and over the aperture therein, said member being centrally apertured and having an internally threaded socket at its lower end, a feed pipe extending through the aperture in the hub portion, said feed pipe having its end externally threaded and adapted to engage the internally threaded socket of the said member, said member having a circular flange, and a cap member having a chamber disposed over the upper end of the said member and adapted to rest upon the flange of the said member, saidcap having discharge outlets communicating with the chamber, all being arranged substantially as shown and described.
