IMPROVEMENT IN GAsoLlNE-BURNER-s.

Specification forming part of Letters Patent No. 200,464, dated February 19, 187B;v application filed January 8, 1878. I

To all whom it may concern v Be it known that I, FoRDYoE A. Lvivmmof Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Gasoline-Burner; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it pertains to make and use it, reference being had to the accompanying drawings, which form partof this specication.

My invention relates to an improved burner for gasoline,for employment in gasoline cooking-stoves; and consists in the combination of devices and appliances herein set forth an claimed.

In the drawing, Figure l is a longitudinal central section of a device embodying my invention. Fig. 2 represents separate views of perforated and slotted bell-crowns.

A is a pipe, through which gasoline is conveyed to the burner. B is a tube situated beneath the vapor-jet and contiguous thereto, and which, with the jet-chamber C, constitutes the vaporizing-chamber, within which the gasoline is converted to vapor. D is a needle or point passing through the vaporjet orifice, and governs the ow of vapor to the burner proper. E is a tube located above the vapor-jet, and leading to the bell-crown or burner proper F. G are arms, which support the burner and the tube E above the jet.

The burner F may be of the usual form of perforated crown, as shown in Fig. 2; or it may be in the form of a bell or crown, slotted about its upper end, through which the flame is emitted. If slotted, as last described, there may or may not be employed an annular ring surrounding the burner just below the slot, for the purpose of spreading the flame, and causing it to burn more quietly.

The slotted crown is shown at F, and its upwardly-flaring ring at f, and the slot at f. F is the ordinary perforated-crown burner. H is a chamber surrounding the vapor-jet, and formed preferably in a single casting therewith. H is a screw-shaft, passing through its side and entering the vapor-jet chamber C. The bottom of the chamber H is provided with one or more perforations, h, preferably a number of perforations surrounding the jetoriiice, and there are also one or more openings,fh,` leading from the upper side of the chamberH down through the chamber through its lower portion. I is a plate or cup for catching the liquid gasoline and furnishing they initial heat.

The operation vof this device is, briefly, as follows: When it is desired to start the flame the shaft D is run down, so as to open the jetorice, permitting the liquid gasoline to over'- flow upon the top surface of the chamber H. This gasoline ilowsdown through the orifice h onto the'plate I beneath. It is then lighted,

and communicates heat tothe chamber H surrounding the jet-chamber, and also communicates heat directly to the jet-chamber C and the adjacent pipe B, converting the gasoline therein to vapor. The shaft D is then again loosened, so as to open the jet-orifice, and the jet, ascending through the tube above, draws air with it into the tube, and the same is mixed in the burner F above, and may be lighted at the perforations or at the slot f. The shaft His now loosened, so that vapor may pass into the chamber H and down through the orifice h, causing a slight flame to be maintained beneath the chamber H between the chamber and the plate or cup I. This flame maintains a strong heat surrounding and in immediate proximity with the vaporizing-chamber, and is entirely independent of the name above.

The lower flame may be increased or dimin. ished at, pleasure, by opening or closing its feed-orifice; by the feed-shaft H'. Moreover, the feed-shaft D may be run up, so as to shut off the main liame at the burner proper; but the lowerfjllame, being fpermitted to burn slightly, will maintain a vapor within the vaporizing-chamber, so that at any moment the If at any time while the upper llame is burn-' ing it is found jthat the QflameE is yellow at places, indicating that the gasoline is not suficiently vaporized before escaping from the jet, and consequently producingimperfect comb ustiomthe defect can be immediately*reinedied by increasing the flame on the plate I.

After the upper or main burner has been extinguished and the flame permitted to die down on the plate I, the upper burner may at any time be ignited by simply turning on the vapor-jet by the shaft D, and then cause a sudden enlargement of the iiame on the plate I by permitting more gasoline to be fed to it. The flame in rising will ignite thegasoline at the main burner above.

I propose generally to make, in connection with the plate I, upturning flanges or ribs i, the object being to prevent any sudden blast of air from extinguishing the flame on the plate I, the said ribs or flanges serving as a windguard or shield. 1

, My invention will admit of various modifications without departing from its principle. Thus the chamber H andthe plate I might be made in a single piece. So, also, the burner Fabove and the tube leading to it might be entirely disconnected from the other mechanism 'and be supported by the frame-work of the stove, or be connected in any other manner. I would have it understood, however, that the plate I may be made with or without the wind-guards.

So, also, I may or may not employ the perforated burner; and if I employ the slotted burner I may or may not employ the plate f, so as to cause the ame emitted from the slot f to' spread out beneath the cooking utensil, for my invention is equally Well adapted for use with any of the well-known bell-crowns.

l. The combination, with the vaporizingchamber and heating-chamber surrounding the same, and formed with passages h and h', of the burning-plate I, substantially as set forth. f

2. The combination, with the vaporizingchamber, provided with suitable valve mechanism, and the heating-chamber, which surrounds it and is formed with the passages h and h', of thevalve H' and the horizontal burning-plate I, provided with or Without Wind-guards z', substantially as set forth.

3. The combination, with the vaporizingchamber and the annular heating-chamber, of the burner proper, the intermediate` vertical tube, and the standards or open support upon which said tube and burner are raised independently above the vapor-jet orice, substantially asset forth. Y

4. The combinatiomwith the burner F, form ed with slot f', of the annular upwardly-Haring plate f, formed on the top thereof below said slot, substantially as set forth.

5. The combination, with the vaporizing chamber, ofthe surroundingchamber H, provided With burningjets h and valve H', for supplying gasoline or vapor to the said jets, substantially as described. y

6. 'The combination, with the main vaporjet, of the chamber H, plate I, Aand orifices h', substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FORDYCE A. LYMAN.
