-VAPOR-BURNER.

SPECIFICATION forming part of `Letters Patent No. 253,498, dated February 14, 1882.

Application filed J une 3, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH H. BEAN, of BondHill, Hamilton county, and State ot'Ohio, have invented a new and useful Improvement in Vapor-Burners, which improvement is fully set forth in the following specification, refer- I ence being had to the accompanying drawings.

The object of my invention is to produce a vapor-burner which shall be more particularly adapted to use in a common cooking-stove, but may be used for any other purpose. Its novelty consists in certain peculiarities of construction, which can be better understood by a detailed description.

Figurelisasectonal view of my burner 5 and Figs. 2, 3, 4, and 5 are separate parts ofthe same.

A represents the burner, which is made of a bowl-shaped casting, with a nipple on the bottom for a screw-thread. This bowl is covered with a cast-iron lid full of perforations, as shown at B, Figs. l and 2. This burner is screwed into the elbow of a compound injector, C. This injector is designed to mix the vapor very largely with the air before entering the burner, and it is composed of a small straight pipe, No. 1, of suitable length, which has an air-inlet, a. This pipe is screwed to one arm of the needlevalve seat D. Onto this pipe is screwed another short pipe, No. 2, cast wit-h one end closed, in which is cuta screw-thread. This pipe is larger than the first, so as to leave a space between it and No. l of about oneeight-h of an inch all round. No. lis caused to project into No. 2 about one-half an inch. Around the base of No. 2 are drilled small airho1es,as shown atb. No.2 is screwed into the end ofthe elbow No. 3, which is larger than No. 2 and' has air-holes, as shown at c. No. 2 projects into No. 3 as did No. linto No. 2. This may be multiplied as often as is necessary to give therequired result, or theburner may be used with No. l and the elbow alone, if desired.

D represents a four-way needle-valve seat, ,l

F, which is packed with asbestus or other suit able absorbent. Up through arm S is drilled a small hole to the center of the valve, into -which is tted the needle-valve G. This valve `stops abruptly at the upper side ot' the small opening l. This opening is made close to the bottom ofthe cup F on its inside and through the arm S. The object of this arrangementis to allow the gasoline, when the needle-valve G is slightly opened, to tlow through the valveseat D into the bottom'otthe heating-cup F. This gasoline' is quickly absorbed by the asbestus in the cup and carried to the top,where it is lighted by a match, and the needle-valve G is then instantly closed. This gives the required amount of heat for starting the burner with absolute certainty, as the amount taken up must be the same every time, and effectually prevents overflow, as is s'o often the case Vwith open cups, and does away with all smoke in lighting, as the liame is very small. This cup may be placed on a pipe leading from the fount, it' desired, and then placed under vthe needle-valve, instead of being fastened to it, and produce the same results. The value of thisi'eat-ure of my invention can be readily seen and appreciated by all users of vapor-burners.

The needle-valves E and G are provided with a sharp, slightly-tapered point, at the base of which is made a square shoulder, as shown at O, Fig. 5. This ei'ectually prevents the con-- tinual expansion of the poiiit of the valve, caused by the oft-repeated closing of the same, and insures absolute certainty in shutting oft thevvapor or gasoline, which is not the case with a tapered needle-valve made in the usual way. This is another feature of great importance, as can be plainly seen by all who understand the nature and construction ofthe needle-valve.

H represents my retort, which is cast hollow and in approximately-the shape otaletter T. Into the outlet No. 4 is screwed the pipe T, which connects the retort with the needlevalve-seat casting D. Into one of the other openings is screwed a pipe connected with the gasoline-supply pipe, and into the other is screwed a solid rod, which rests on one of the sidej ambs of thestove to hold the burner firmly in place.

Some of the advantages of my invention are the large amount ot' air mixed with the vapor, the safety, certainty, and convenience of the lighting, and the way in whichV the burningvapor escapes from the burner, all coming out IOC) 15 jector C, and burner A, as and for the purpose at the top of the burner and in direct contact with the object to be heated, instead of at the side of the burner, as is the usual manner.

Iam aware that attempts have been made by Holland, Humiston, and others to adapt the vapor-bdrner to the coininon cook-stove; but owing to the expensive nature of their burners, or the danger of overflow in lighting causing dangerous explosions, they have proved nearly useless for the purpose intended.

Having thus fully described my invention, what l claim isv l. In a vapor-burner, the combination ofthe four-Way needle-valve sent D,compound inset forth.
