HYDROCARBON-BURN ER.

SPECIFICATION forming part of Letters Patent No. 562,537, dated June 23, 1896.

Application filed April 21, 1894:. Serial No. 508 ,502. (No model.)

To all whom t may concern.-

Be it known that I, WILBERT J. J ACKMAN, a citizen of the United States, residing at Lima, in the county of Allen and State of Ohio, have ments in Hydrocarbon-Burners; and I doV hereby 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 an improved hydrocarbon-burner, and belongs to that class thereof known as vaporizers and airmixers, in which the oil is vaporized as it passes to the burner, and is mixed with a certain amount of air prior to ignition.

The object of the invention is to provide a burner of such construction that all the oil will be thoroughly vaporized before passing to the burner proper, and another object is to provide for the vapor issuing to the burner in the form of a jet, so as to carry into the burner an appropriate quantity of air.

Vith these ends in view the invention coning-pipe connected therewith, a back-pressure pipe for receiving the unvaporized oil, a cut-off valve through which the vapor passes, an air-mixer arranged upon the valve-casing, and a burner proper located above the mixing-chamber and communicating there with said burner.

The invention consists also in certain details of construction and novelties of combination which will be fully described, and hereinafter particularly pointed out in the claims.

In the drawings forming a part of this specification, Figure l is a side elevation, partly in section, of my improvements. Fig. 2 is a vertical sectional view of the burner proper, mixing-chamber, and cut-off valve; and Fig. 3 shows a sectional view of a burner adapted for use in heating-stoves, the burner shown in Figs. 1 and 2 being adapted principally for use in cooking-stoves.

In carrying out my invention I employ an oil-supply pipe A, which is connected with a suitable tank or reservoir, (not shown,) and the oil is passed therethrough by gravity or by air pressure, as desired. This pipe A leads to a regulating-valve B, and connected with the opposite side of this valve is the retort or vaporizing-coil C, comprising several turns c and the depending end portion c', which end portion is connected with ,a condensing-pipe D by means of a `reducing-coupling d. This condensing-pipe D is considerably smaller in diameter than the pipe C, the purpose of which is to cause any small unvaporized oil globules or particles passing therethrough to unite and separate from the vapor as the latter passes onward to the burner. The lower end of this pipe D is connected with a pipe E by means of an elbow e, and this pipe E is connected with the eut-oif' valve F by means of a T- coupling e.

In the opposite end of the coupling c is screwed a pipe or cylinder G, closed at its end by a cap g. This pipe I term a back-pressure pipe, and its purpose is to receive any large globules of oil that may have passed through the coil without being thoroughly vaporized and been carried by their momentum past the vapor-duct leading to the burner. Any oil entering said pipe is thus retained therein and prevented from passing onto the burner, and

while so retained it is gradually vapori/Zed by the heat from the hot vapors of the j et-oriiice when the burner is in full operation and then passes up into the burner.

Projecting upward from the cut-off valve Fis a union f, which is adapted to receive my improved burner. This burner comprises a pipe H, which screws upon the union f, and is contracted at its upper end, providing a very small aperture h for the passageof the vapor, thus causing it to issue in the form of a jet. Connected with the pipe Il (either integrally or by attachment) is a flash or drip pan I, said pan surrounding the pipe, and being provided with a surrounding flange c', of any suitable depth. Extending upwardly from the end of pipe II are the arms k lo, supporting a mixingchamber or hood K, which is provided with a closed top. Passing through this top and extending some distance into the chamber or hood is the delivery tube or pipe L, upon the upper end of which fits the burner proper, M, the lower end of said tube or pipe being eX- panded to receive the commingled air and gas or vapor.

The hood K and depending portion of the IOC tube L constitute an annular air-chamber above the jet-orifice, which receives and confines such parts of the vapor as do not pass into the tube L, and admixes air therewith. The hood K also protects the jet of vapor from disturbance by air currents, and directs said currents to facilitate their admixture with the vapor.

It will be noted that the tube L, pipe Il, and cut-off Valve F are all in alinement with one another, so that the vapor has a straight and unobstructed passage into the burner.

The burner proper, M, comprises the upper perforated plate m and the lower plate m, secured to each other and separated a suflicient distance to permit the expansion of the mixed air and vapor within the same. Passing through the burner upon opposite sides of the center are the air flues or passages m2, which serve -to provide air at the point of ignition, thus insuring satisfactory combustion and also spreading the flame. The lower plate has a central opening m3, and surrounding` the same is a collar or flange m4, by means of which the burner is fitted and held upon the delivery-tube L.

The regulating-valve I3 and cut-of valve F are substantially the same in construction, each consisting of a cylindrical casing N, closed at each end by means of screw caps or heads n and n. lVithin this casing N is arranged the valve proper, consisting of two parts U2 and U3, respectively connected by a screw and socket, as shown, each section having a head and flange n4, which lits and works in a rabbet U5, formed at each end of the cylinder, and between the ends of sections and the caps of the cylinder are arranged the packing-wastes no. The valve or plug proper has a passage nl, which is adapted to register with opening 'a8 in the opposite side of the casing, and it will be observed that the diameter of these openings and also of the passage nl is considerably smaller than that of the communicating pipes, the purpose of which is to give the vapor considerable pressure as it issues to the burner.

The Valve or plug is made in two parts for the purpose of inserting it in the casing, and by constructing it with heads at each end and packing them in the manner shown a perfectly gas and oil tight valve is obtained.

The valve is operated by means of a stein 019, which is threaded intermediate of its ends and works in a threaded yoke n10. This stem can be made in one piece or in two parts and connected by means of a socket.

The diameter of the bore a" canbe made any suitable size, according to the purpose for which it is intended. In operation the oil is fed from the tank by gravity or air-pressure and passed through the regulating-valve B, which has been previously set at the desired point. AThe oil then passes through the coil C, down into pipe D, through pipe E, valve F, and pipe II. IIere it flows out upon the flash or drip pan I, where it is ignited. Vhile the oil upon the pan is thus burning, the oil passing through the coil C becomes vaporized, and passes through the same course as the oil previously described. It issues,however, from the pipe Hin the form of a jet and passes up into the air-mixing chamber K, and the commingled air and vapor then pass through the tube L into the burner, where it is consumed, the combustion being assisted by the air mixed in the chamber K and also brought into contact with thev flame by means of the air flues or passages m2. rlhc condensing-pipe D and contracted passages of the valve and pipe II all tend to feed the vapor to the mixer with considerable force, so that a current or suction is created, thus drawing and commingling the air in a better manner.

Having thus described my invention, what I claim isl. In a hydrocarbon-burner, the combination with a burner, and a retort, of a condensing-tube through which the vapor passes to the burner, and a supplemental pipe or tube communicating at one end with the condensing-tube, and closed at its opposite end, and adapted to receive globules of unvaporized oil which are carried past the Vapor-dis charge orifice, said condensing-tube being of relatively smaller diameter than its inlet and discharge connections.
