AMANDA T. JONES, OF CLINTON, WISOONSlN.

OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 225,839, dated March 23, 1880.

Application filed September 27, 1879. 7

To all whom it may concern:

Be it known that I, AMANDA T. JONES, of Clinton, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Oil-Burners; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which-- Figure 1 is a vertical sectional view of a device embodying the improvements in my invention. Fig. 2 is a plan view of the cover, and Fig. 3 is a detail view.

The nature of this invention relates to an improved oil-burner and feed mechanism constructed and arranged for the purposes of steam-generation, metal-smelting, glass-manufacturing, and the like.

In order to insure the best combustion of crude petroleum or other inflammable oils, the oil should be thinly spread over the broadest possible burning-surface, fully exposed to the air, and the feed so regulated as to prevent overflow. To further the essential requisite of safety during combustion, the burner should be so arranged that when combustion is carried on upon an extensive scale it will be impossible for any resurgent flame to reach the supply pipes and tanks containing the supply of oil. It is also desirable that the oil shall be fed to the burner in such limited quantities that no dangerous amount of gas will be generated in the furnace or burning-chamber at any subsequent relighting of the fire; and to such end my invention is designed to carry into practical effect the principles above mentioned.

Referring by letter to the drawings, A designates a burner or crucible, which is to be set into the fire-box or combustion-chamber of any furnace, either alone or in conjunction with others. This burner consists of a shallow pan provided with an open downward extension, I), which admits of its connection with a supply-pipe, through which the oil is admitted into the pan. This burner or pan is formed with a grooved flange, 0, around its rim, the same answering the double purpose of guarding against any of the surface-oil from dripping down the sides of the burner, and of forming a restingledge in setting the burner in level position within the furnace.

An inner ledge or shelf, d, entire or broken, runs around the inner side of the burner or pan, thereby forming a seat for the cover E. This cover should he, say, about one-fourth less in thickness than the depth of the pan in which it lies, thereby leaving about that space beneath it in the pan. Such space is left so as to be filled with oil during use. The cover has a corrugated or ribbed upper surface, and is perforated, preferably, between the ribs, thereby allowing the oil to rise and lie either in an entire sheet upon the cover or in sheets between the corrugations only. The cover is provided with knobs or handlesf, so that it may be readily lifted; or it may have notches g, which admit of the insertion of hooks, so that it may be lifted when the interior of the burner requires attention.

The burner, with its closely-fitting cover, may be of any desired shape, either round, square, or otherwise, the object being to give the broadest burning-surface to the air that may be needed, according tothe' size of fur nace to be heated.

The pipe h, which enters the burner from below, has a plug or stop-cock, h, at its lower end, so that the same may be opened to strain off or cleanse the burner should it become clogged.

The pipe i, leading from the burner, is for the admission of air when the burner becomes sufficiently heated to insure the volatilization of. the oil beneath the cover. In this way there will be a certainty of consuming all of the carbon, and of thus leaving a clean pan.

Leading off horizontally from this perpendicular pipe his a pipe, 7:, provided with a stop-cock, 7a. This extends to and opens in the cylinder L, which is to be located outside of the furnace.

The cylinder L is provided with a pipe, I, which has a stop-cock, and is intended to drain off sediment,

M designates the pipe which connects'the cylinder with the oil-tank from which the supply of oil is derived.

The mechanism for automatically opening or closing a cock, at, in the pipe 0, whereby the feed to the cylinder shall be controlled, is as follows: P designates a hollow ball, which is designed to float upon the surface of the oil in the cylinder L, and hence rise and fall with 2 eeaeeo the same, so as to automatically open or close the cock bymeans of intermediate connectingrods. This hollow ball is secured upon the end of a vertical rod, 19, which works through the top of the cylinder. The upper end of this rod is screw-threaded, and is adjusted in a rod, q, so that the ball can be raised or lowered at pleasure. Said rod is provided with a nut, q, whereby it may be readily manipulated.

If desired, the rod 12 maybe made hollow atits upper end and screw-threaded, so as to fit upon instead of in the short rod g. In lieu of this, however, the shaft or rod q may be made tubular and provided with a scale, as in Fig.3. In this case the rod 19 will be arranged to slide within the same, and be provided with an indeX, qso that the exact height of the ball may be known. Rod q will be slotted, so that the pin of the index or pointer may work along the same, and it will be provided with a setscrew, q so that the rods may be secured together. In order that the rod q may be connected with the arm 4, which operates the cock, so that during operation the rod 10 shall have a true vertical movement, I provide between the arm r and the rod q a knuckle-joint, consisting of the short rod 8, pivoted at one end to arm r and atthe other to the'rod q.

The burner being set in the fire-box with its upper surface about on a level with the surface of the fluid in the cylinder and the ball properly adjusted so as to close the cock, there will be no overflow when the cook between the cylinder and the burner is closed. If, now, this cock is opened, the oil will flow into the burner until the surface thereof is covered. At this point the oil in the cylinder will be about upon a level with the oil upon the burner, and the cock will be opened by reason of the descent of the ball and con sequent operation of the rods and arm. As

the oil in the cylinder rises, however, the ball ascends until the requisite limit to prevent overflow is reached, and at this point the cock will be closed.

It will be seen, therefore, that the object of the cylinder and valve mechanism is to obtain and keepa certain fixed fluid-levcl,which may be varied at pleasure byraising or lowering the ball.

By the above distribution of oil upon the burner the oil will be readily ignited and will burn without material deposit of carbon. The addition of an ail-blast will not be necessary, though a slight blast of air or steam may be used, if desired, .so as to efiect more perfect combustion.

When desired, two or more burners maybe employed, the principles heretofore explained being observed in their arrangement.

What I claim is 1. The herein-described burner A, provided with a perforated and ribbed cover, E, substantially as set forth.

2. In combination with the burner A, cylinder L, and intermediate connectingpipes, a stop-cock adapted to control the flow of oil through the supply-pipe M, and actuating mechanism composed of a float within the cylinder, a rod connecting with the float and passing up through the cylinder, an arm for operating the cock, and a knuckle-joint connecting said arm with the float-rod, all substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

AMANDA T. JONES.

In presence of- Mrs. MELL RoBBINs, CHARLES D. ROBBINS.
