AUTOMTIC GASOLlNE-BURNER.

SPECIFICATION forming part of Letters Patent No. 445,572, dated February 3, 1891.

Application tiled February 5, 1890. Serial No. 339,326. (No modeL/ T @ZZ who/1t it may concer/L:

Be it known that I, NELSON NEWMAN, of Sprlnglield, in the county of Sangamon, State Vof Illinois, have invented new and useful Im- Vprovements in Automatic Gasoline-Burners;

and I do hereby declare that the lfollowing' is a full, clear, and exact description of my invention, which will enable others skilled in the art to which it appertains to make and use it, reference being had to the accompanying drawings, forming part of this specii'ication.

My invention relates to an improvement in automatic gasoline-burners; and the objects of my invention are, flrst, to provide a burner which is adapted for consu ming `gasoline for illuminating purposes, either indoors or out of doors, and, secondly, to provide means for automatically igniting and extinguishing the burner at predetermined intervals of time.

My invention consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of a gasoline-burner embody' ing my improvements. vation of the same. tional view.

l designates the suppl y-pi pe, through which the gasoline or other hydrocarbon fluid is supplied to the burner 2. To the upper end of this supply-pipe is secured the shell of 'a regulating-valve 3, which has an axially-turning plug 4, to which is secured a lever 5, and this lever is arranged in the paths of projections on a revoluble dial G. The dial is carried by an axially-turning shaft 7, which is adapted to be rotated once in twenty-four hours by any suitable motor or clock-work mechanism arranged in the case S on a base i). This clock-work mechanism is not shown, as it maybe ofany preferred Well-known construction. The dial is inscribed with numerals corresponding to the hours of the d ay and provided with two concentric series of apertures lO 11, in which pins l2 13 are adapted to be inserted, respectively. The

Fig. 2 is a front ele- Fig. 3 is a vertical sccpin 12 is adapted to strike the long arm of -the lever to turn on the flow of gasoline, and the pin 13 is adapted to strike the short arm of the lever to shut off the flow of the gasoline by partly turning the valve, as will be readily understood. By adjusting the pins in the appropriate openings they may be caused to turn on and shut olf the gasoline at any hours desired. Rising from the valve is a pipe l5, which carries the burner 2 at its upper end, and in this pipe or tube is placed a fibrous filling of cotton wick or other suitable material 16 to conduct the gasoline to the burner.

The burner consists, essentially, of a metallic plate 20, having the curved flame-deilector 2l, the plug 22,and the concave iianleplate 23, arranged on the plug above the outlet thereof and over the opening in the plate, through which passes the flame-jet from the ignitor or auxiliary burner 30, arranged bclow the burner 2. The plate 2O is provided with an internally-threaded hollow boss 24: on its lower side, which is screwed on the upper end of the pipe l5, and in this hollow boss of the plate 2O is fitted the lower end of the plug 22, which is held in a fixed position immediately over and in line with the pipe l by means of an upwardly extending curved or bent arm 25, integral with the plate 20, which arm rests on the upper extremity of the plug, as shown, to prevent said plug from being elevated or blown out of the plat-e 20 and its seat therein by the expansive force ot' the gas generated by combustion of the gasoline supplied through the pipe l5. The plug 22 is provided with a continuous axial and transverse bore or passage 40, which opens through one endV and the lateral face of the plug, and immediately over the transverse opening of said passage is arranged the concave fla1ne-plate 23, which serves to direct the gas or vapor over the vertical aperture 26 in the bottom of the plate 20. The deiieeting-plate 2l curves upwardly and inwardly, so that its upper edge overhangs the horizontally-arranged concave flame -plate 23, and the latter plate terminates a short distance from the deiector-plate, so that an intervening space is provided between the upright deI'lcctor-pl.itc 2l and the flame-plate 23 for the passage of the name, which is spread out by the delector-plate 2l.

Below the detlector 2l of the plate 20 is arranged the vertical ignitor or auxiliary burner 30, the upper end of which is arranged within but out of contact with an integral bell-shaped hood 3l, which depends from the lower side of the plate 20, and in the center of this hood is formed the vertical aperture 26, which is in alignment withtheignitor or auxiliaryburner. 'lhisignitor 30 consists of a foraminous jacket formed of a series of two or more concentric cylinders, of wire-gauze or sheet metal, a seat or base 32, to which the jacket is secured, and a plug 33, fitted in the upper open end of the pipe 34which conducts the gasoline from the pipe l at a point below the regulatingvalve to the ignitor. i This seat or base 32 is rigidly secu red to the pipe 34, and in the plug is formed a very small passage 35, that permits the passage of a small quantity of gasoline through the plug to the interior chamber formed by the foraminous jacket.

The operation of my invention is as follows: The gasoline is constantly supplied or conducted by the pipe 3l from the pipe l to the ignitor or auxiliary burner, and the latter is ignited in any suitable way, so as to heat the forarninous jacket and the plate 20. The ignitor burns constantly or as long as may be desired, so as to maintain the plate 20 in a heated state sufficiently to vaporize the gasoline, and when the revoluble dial in its rotation causes the pin l2 to impinge against the lever the regulatingw'alve is opened. The gasoline is then conducted through the wick 16 to the passage in the plug-22, and the gasoline is vaporized by the heated plate 2O and the plug, so that it issues 'from the passage of the plug in the form of gas or Vapor, and is directed by the horizontal plate 23 across andV over the opening 26, at which point the gas is ignited from the jet issuing from the ignitor through vthe opening 2G, and the iiame is spread by the curved upright plate 2l. The burner continues to vaporize the gasoline and consume the gas until the dial rotates suliiciently to cause its pin 13 to ifnpingeagalnst the short arm of the lever, which operates to close the valve and cut oit the supply of gasoline to theburner; but the ignitor orauxiliary burner continues in operation, because it receives its supply of -gasoline from the p1pe l at a point below the regulating-valve iin said pipe, so that the apparatus is in condition for operation when the dial shall have rotated sutliciently to cause its pin l2 to again open the regulating-valve. The foraminous jacket of the ignitor admits of the free passage of air to the interior of the ignitor or auxiliary burner and excludes drafts of air from the flame. The overhanging hood on the plate 2O prevents downward drafts of air in the ignitor.

Having thus describedl my invention, I claiml. The gasoline-lournercomprising the supply-pipe having the valve, the Wick-tube rising above the latter, the plate 20 on the upper end of the wick-tube and having the curved defiecting-plate 2l, with a vertical opening 26 in its base, and the depending hood 31, the plug 22, rising from plate 2O and having the aperture 40 and thellame-plate 23, and the ignitor 30, with its upper end in the hood 31, the ignitor being connected to the supply-pipe at a point beiow the valve, substantially as described.

2. In a gasoline-burner, the plug 22 in the upper end of the Wick-tube and having the opening 40 and the tiameplate 23, and the plate 20, attached to the upper end of the Wick-tube, said plate having the curved dci'lecting-plate 2l, for the purpose Set forth, and the arm 25, which latter has its upper end bent over the top of the plug, substantiallyas described.

In testimony that I claim the foregoing I hereunto append my signature.

NELSON NEWMAN. IVitnesses:

WM. R. BOWERS, E. S. DAY.
