VAPOR-BURNER.-

SPECIFICATION forming part of Reissued Letters Patent No. 9,922, dated November 8, 1881, Original No. 188,283, dated March 13, 1877; Reissue No, 9,602, dated March 8, 1881. Application for reissue filed August 22, 1881.

A of Ohio, have invented new and useful Improvements inVapor-Burners, of which the following is a description.

To enable others to make and use the same reference will be had to the accompanying drawings, making part of this specification.

The invention consists in such parts and combinations as will be hereinafter more fully set forth and claimed for heating purposes.

In the drawings, Figure l represents a vertical section offa vapor-burner embodying my invention. Fig. 2 is an enlarged view ol' that part ot' the burner embracing the expansionchamber and valve. Fig. 3 is a detached view of the base or adjusting plate. Fig. 4 is a detached view of the perforatedy cap or dome.

Like letters refer to like parts in the several views.

In the drawings, A is a pipe which leads to and is connected with an elevated reservoir, (not shown in the drawings,) whence the gasolineor hydrocarbon iiuid comes for burning in the ordinary well-known manner. To the said pipe A is connected the vertical tube B, the upper part of vwhich forms the vaporizingchamber D, Fig. 1. Around said part of the 3oztube is placed the heating-cup C. Above the vaporizing-chamber is situated the expansion chamber N, from which leads the passage or outlet a. The said chamber is beveled or funneled at the lower part, as shown at d, Fig 2, and the., angle of the bevel is made to correspond with the tapering end of the screw-pin valve E,so as to secure a tight and close fit to prevent leakage. The lower part of the said valve-rod is screw-threaded and works in the female screw in the projection It. Said rod is provided with a hand-wheel, P, or other suitable device, by which the supply of the vaporized fluid is regulated.

H isatop plate,provided with acentral opening,and is supportedon the arms G G, which rise from the upper part of the vaporizingchamber D, and admits of a free open space between the outlet a and the burner, for the purpose of securing combustion.

The adjusting-plate I is provided with a depending guide-pipe, b, screw-threaded on the outside,whereby,in connection with the threaded opening of the top plate, the said adjustingplate I can be elevated or lowered relatively to said top plate. The pipe b is situated directly over the outlet a, from whence the vaporized duid passes through said pipe into the perforated combustion cap or dome K. The plate I is also provided with openings or jet# apertures. The perforations or openings are seen at c c. The object in making the plate I adjustable is to secure a blue or heating flame. This desired result can be reached in all instances with my improvement by simply adjustin g upward ord'ownward the plate I, as circumstances may require.

K is the perforated cap of the combustionchamber K. It tits to the periphery or sides of plate I loosely, so that it can be taken otf or removed when desired. The cap is fitted to the plate by means of a shoulder or dange on the lower edge of the cap, as seen in Fig. 1 at e e. One advantage thereby secured is that in case the opening or outlet a. becomes clogged or stopped up, the instrument by which to clear it can be passed through the tube b frbm above in a line with the axis of outlet a, thus diminishing the liability of injury to the outlet, as weli as facilitating its cleaning.

The combustion-chamber Kl is formed by the interior of the cap K, and the door or base thereof by the plate I. The upper section or dome is made without a door or bottom and rests upon the plate I, to which it is removably connected, and the two sections or parts forming the chamber are held in placev by a circular flange at the junction of the said sections, Ywhich holds and prevents lateral dis-4 placement of' the sections.

Combustion-chambers have been made, from mere convenience of construction,of thin metal, in two parts, as in the patent to Love, February 8,1870, No. 99,689; but he expressly states that the two parts are to be brazed together;

IOO

they join, and the weight of the cap keeps it in place; but it can readily be removed at any time when required.

By means of the expansion-chamber N a steady and even ow of the vaporized duid through the outlet a is secured, and any of the fluid which escapes vaporization in the chamber D and enters the expansion-chamber N is` vaporized therein, so that by this improvement a thorough vaporiziugof the gasoline or hydrocarbon fluid is secured.

The operation of the vapor-burner is as follows Gasoline or hydrocarbon fluid enters the tube B by hydrostatic pressure. To light the burner, turn the wheel P so as to open the valve E. This will cause ajet of fluid to pass through the opening a int'o the' combustionchamber K', striking against the roof or top thereof. The iluid will then run down into the cup G, and when it is about half full close the valve E to stop the dow. Then light the fluid in the cup and let it burn out. This operation heats the upper part of the tube B-suicieutly to cause vaporization of the fluid to take place in the chamberD thereof. Now, when the valve is opened again, the vaporized iluid passes into the combustion-chamber andissues at the jetopeuings c c', where, when lighted, it burns with'a blue flame, which can bc regulated, as desired, by opening the valve more or less. The vaporiziug iluid that passes from the interior of the cap K through the jet-apertures c' issues between the top plate, H, and the adjustingplate I and burns with a blue flame,

which flame surrounds the burner. The heat from the top plate, H, and from the burner is transmitted by t-he arms G G, and by radiation to the upper part of the tube B to a sufticient degree to continue the vaporization of the gasoline in the chamber D, which was secured in the rst instance by the direct application of heat by means of the ignited oil in cupC.

Any number of these burners may be connected with and supplied by the same reser voir, limited, of course, only tothe capacity of the latter.

The interior of the guide-pipe b is preferably made tapering, with the smaller end opening into 'the combustion-chamber K'.

A removable perforated cap of sheet metal has heretofore beeuused on illuminating-burners with acurvcd base, but such cap fitted the base so closely as to be practically immovable. My burner is so adjusted on the flange or base 'platethat it can readily be. removed when either hot or cold. ,It is made of cast metal, and by making it of the form shown the use of a core in casting it is avoided, which had not been done in the maufacture of others. tate audc'heapen the manufacture. This method of casting has particular advantages in this case, in that it secures a smooth interor'surface, which hasimportant relations to the per-y fection of the gas-burning perforations and to the matter of the deposit of soot and incrustation, as will be readily understood.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The removable perforated cap K, tted on the base-plate, and in combination with said plate and with the guide-pipe and jet-orifice, substantially as and for the purpose described.

2. In combination with the vaporiziu'gchamber D, expansion-chamber N, and screw-valve E, the adjusting-plate I, guide-pipe b, and re-V movable cap K, substantially as and for the purpose described.

3. The combination, with thc vaporizingchamber D, expansion-chamber N, and screwvalve E, of the adjusting-plate I, guidepipe b, top plate, H, and removable cap K, substantially as described.

4. The combination, with vaporizing-chamber D, expansion-chamber N, screw-valve E, and heating-cup C, of the adjustable plate I, guide-pipe b, top plate, H, and removable combustion cap K, substantially as described.

5. The combination, with the vaporizingchamber D, expansion-chamber N, screw-valve E,'and heating-cup C, of the arms G G, adjusting-plate I, guide-pipe b, top plate, H, and

6. A perforated cap, K, adjustable to a bottom or base plate, I, constructed as described, the two forming a combustion-chamber, substantially as and for the purpose set forth.

7 The combination of the removable perforated combustiou-capK with base-plateI and ,gnidepipe b, having a central opening arranged iu relation to the gasvalve orifice, substantially as and for the purpose described.

8. A combustion-chamber made of two castmetal sections, K andy I, the upper one forming the dome or cap and the lower one thcebase or bottom thereof, and a guide-pipe communicatin g with said chamber, substantially as and for the purpose described.

In testimony whereof I aiiixk my signature in presence of two witnesses.
