VAPOR-BURN ER.

SPECIFICATION forming part of Letters Patent N o. 400,498, dated April 2, 1889. Application tiled May 1**7, 1887. Renewed February 23, 1889. Serial No. 300,995. (No model.)

o all whom it may concern.-

4Be it known that I, CHARLES H. SHULTZ, a citizen of the United States, residing at St Joseph, in the county of Buchanan and State of Missouri, have inventeda new and useful Improvement in Vapor-Burners for Gas- Stoves, of which the following is a specification.

My invention relates to an improvement in vapor-burners; and it consists in the peculiar construction and arrangementof the devices, as will be more fully set forth hereinafter", and particularly pointed out in the claims'.v

In the drawings, Figure l is a vertical sectional view of a vapor-burner embodying my improvements. Fig. 2 is a top plan view. of the same. Fig. 3 is another form of the packing device forthe needle-valve..

A represents a hollow annular casting,

which constitutes the generating-chamber.

This chamber is preferably made annular in form and surrounds a central open space, B, which is open from top to bottom throughout the `height of the chamber. From one side of the chamber A projects an offset, C, which per end of the usual stand-pipe, D, by a screw- From the opposite side of the generating-chamber extends avaporpipe, F., to the lower end of which is attached a horizontal sleeve, F,fwhich has its closed apertured extremity projected toward the stand-pipe. ln this sleeve is located the needle-valve G. The outer end of the horizontal sleeve F is provided with screw-threads, as shown in Fig. l, and the closed inner end of the said sleeve has a conical central aperture, R.

S represents a packing-gland, which is cylindrical in shape, and is provided with interior screw-threads adapted to fit the thread on the outer end of the sleeve F. Y

Gr represents the needle-valve, which fits in the sleeve F, and is provided at its inner end with the usual conical needle-point extending through the aperture R. The outer portion of the needle-valve is provided with screwthreads U, which engage a threaded opening in the bottom of the gland S.

V represents packing material, which is arranged in the packing-gland on the outer end suitable manner.

- from'the outer end of the sleeve F.

W represents a handle, which is secured to the lower depending end of the needlevalve by means of a setscrew, X.

H represents a combined mixing-chamber and burner-head, which has its upper end part way inserted in the space and arranged concentrically in the said space. The lower end of the mixing-chamber and burner-head is provided with an integral tube, I, which is open at its outer end, and is projected toward the inner end -of the sleeve F. This mixing-chamber and burner-head may be supported. by an arm, K, projecting from the stand-pipe, as shown in theaccompanying drawings; or it may be supported in any other The upper end of the mixing-chamber and burner-head is provided with a number of horizontal radial openings, L, some of which are slightly above the lower side of the generating-chamber and the others are below the same.

M represents a drip or oil cup, which forms an annular flange-extension of the cap of the mixing-chamber and burner-head. This cap is secured in position by means of the vertical clamping-bolt N, as shown in Fig. l.

The operation of my invention is as follows: In starting the burner in operation a small quantity of oil is placed in the cup N and is ignited, thereby causing the generating-chamber, which is directly over the oil-cup, to become thoroughly heated. When the oil is permitted to ilow from the reservoir (not shown) through the stand-pipe D into the generatingchamber, it becomes vaporized therein, and the vapor passes through the pipe E and the sleeve F and is directed by the aperture in the said sleeve into the burner-head through theopen tubel thereof. As the said vapor entersthe' burner-head it sucks the air into the burner-head, which air mingles with the vapor and renders the latter combustible. As the oxygenized vapor passes outward from the burner in small jets through the openings L, it burns in a IOO flame, which strikes against. the lower and inner sides of the annular generating-chainber, and thus keeps the said generat or so hot that it is caused to generate vapor as fast as it is consumed by the burner. Exterior air is drawn upward by the ame and heat through the space B and around the upper end of the burner ll in suiicient qualitities to insure perfect combustion of the vapor.

Particular stress is laid on the construction of the burner-head and commin glin g-ch amber with the series of perforations in the sides above and below the lower side of the generator, whereby the jets of name are projected laterally against the bottom and lower sides of the generator-chamber, causing the latter to be thoroughly heated to effect the vaporization of the oil. By havingl the jet-openings in the sides instead of at the top the flame is caused to strike the bottom of the generator-chamber and cannot escape without touching the chamber. Again, the burner is arranged out of contact with the lower side of the generator, to leave a space through which air can escape through the space B of the generator to feed combustion.

The construct-ion of packing shown in Figs. l and 3 is claimed in my application, Serial No.238,3i8, filed May-16, 1887. In Fig. 3l show an improved form of packing. The`gland S screws upon the tube F in the manner shown in Fig. l; but in the present instance l employ a cap, XW, held rigid on the valve-stem by a set-screw, X2, and this cap XW screws over the threaded outer end of the gland S. By this arrangement the cap XW is caused to screw or unscrew over the threaded outer end of the gland by the movement of the valve G. The object of this construction is to dispense with the necessity of threading the valve, as in the construction shown in Fig. l, and at the same time secure the proper movement for the valve. By the turning of the valve the box N l2 works over the outer end of the gland to give the proper movement to the valve. By this means the turning of the valve G effects the packing thereof, and leaking of the gas is entirely overcome. Should any gas escape from the valve, it will be arrested by the packing-gland. No stuffingboxes are required to be used in this packing device, and this is a point gained, as every one familiar with this art will admit.

Particular stress is laid on the arrangement of the burner within the air-space B of the generating-chamber, whereby the said airspace is not closed by the burner,but a space is left around the burner and between it and the generating-chamber to allow a free upward draft of air for the purpose of assisting combustion.

It has been found in practice that unless the fiames jets are supplied with a suiiicient quantity of air the jets will be of a yellowish color and cause smoking, with an offensive odor. By my construction the flame-jets are supplied with air in such quantities as to insure perfect combustion,causing the flamejets to be of a purplish color, devoid of smoke or odor.

l ain not aware that any vapor-burner havingl a central opening or air-space, B, has ever been constructed with the burner located in the same but not closing the said air-space, so that a free upward current of air around the burner is insured at all times.

Having thus described my invention, I claiml. In a vapor-burner, the generating-chamber A, surrounding a central space, B, which is entirely open both at the top and bottom, combined with the burner-head arranged below the generating-chamber and having its upper end inserted part way into the open space B, the top of thc burner being closed and imperforate, and two or more series of jet-openings, L, in the sides of the burnerhead, one series being above the other, so that the openings L are both above and below the bottom of the generating-chamber, as set forth.

2. In a vapor-burner, the generating-chamber A, surrounding a central space, B, which is open at the top and bottom, and the combined mixing-chamber and burner H, arranged below the generating-chamber, the burnerhead being inserted into the space B, and having a removable cap provided with a hanged extension, which forms an oil-cup, M, the top of the cap being imperforate, and the perforations L in the sides of said cap, as set forth.

3. In a vapor-burner, the generating-chamber A, surrounding a central space, B, which is open at the top and bottom,and the vaporpipe E, extending from thc chamber, in coinbination with the combined mixing-chamber and burner H, made separate from the generating-chamber and having its upper end inserted part way into the space B and its lower end formed with an integral tube, I, which is turned to one side toward the pipe 1Q, and the needle-valve at the lower end of pipe E, adjacent to the end of tube I, and the jet-openings L in the sides of the burner, said openings being both above and below the bottom of the generating-chamber, the top of the burner being imperforate, as set forth.

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