GASOLENE-LAMP.

SPECIFICATION forming part of Letters Patent NO. 794,972, dated July 18, 1905.

T0 at whom, it may concern.-

Be it known that I, BLAIR A. EsTEP, acitizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gasolene-Lamps, of which the following is a full, clear, and exact description.

My invention relates to gasolene pressurelamps. Heretofore the tanks of these lamps have been arranged in such a position that, considering the size it is necessary to make them in order to hold suffici'ent oil, they cast a very large shadow. As heretofore constructed the burner of these lamps had to be separated from the tank by a sinuous pipe in order to accommodate the presence of the cleaning-needle valve thereof, and thus deprive the tank of the benefit of the heat generated in the burner to promote the generation of gas. The object of my invention is to overcome these objections. This I accomplish in a simple and effective manner, substantially as hereinafter fully described and as particularly pointed out in the claims.

In the drawings, Figure 1 is a front elevation of a gasolene-lamp embodying my invention, having the upper portion of the hanger thereof broken away. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical transverse section of the burner separated from the tank and drawn to an enlarged scale. Fig. 4 is a horizontal transverse section taken on dotted line 4 4:, Fig. 3, looking in the direction indicated by the arrows. Fig. 5 is a front elevation in detail of the cylindrical piston employed to admit gas into the combustion-chamber.

Referring to the drawings, A represents a circular or other suitably-shaped tank, which stands on edge, as shown in the drawings, The front of this tank has a suitable elbow Z) projecting therefrom, which has a suitable pressure-gage B secured to the end of its vertical branch, and preferably at a point above this pressure gage the walls of the tank are pierced by and have secured therein an ordinary valve-controlled air-inlet C. The tank 5 O has a suitable plugged inlet 0, through which the gasolene is supplied thereto, extending through the rear side thereof, and the gasolene thus supplied to said tank is forced up by the air-pressure through the pipe 0Z into the screw-threaded stud e of the burner, which latter is tapped into the circumference of the tank at a point opposite and in alinement with the center of the base of the same. The burner D consists of a suitable casting extending vertically upward in alinement with the stud e, which is provided at a suitable point above the tank with two diametrically opposite laterally-projecting arms E and F, the latter of which is preferably slightly longer than the former. The upper part is drilled longitudinally and centrally from its upper end to form a combustion-chamber L, and it has lateral openings or air-ports 7" at its lower end and has seated in its rabbeted upper edges a wire-gauze cap M. The longer arm E has a longitudinal central passage f drilled or otherwise made therein, which extends from its outer end into the vertical portion of the burner D, and this passage f communicates with the upper end of the bore of the stud e by means of the passage 9, extending centrally through-the brace g, connecting said arm E and said stud, substantially as shown in the drawings. The communication between passages f and g is controlled by a screw-threaded spindle-valve H, whose conical end is adapted to engage a corresponding seat at the confluence of said passages, and this valve H extends longitudinally and centrally out through a gland-nut 71. at the outer packed end of arm E and is manipulated by a suitable milled wheel on its extremity.

The inner end of the passage f strikes into the lower end of a vertical passage I, that extends to and communicates with an annular chamber in the upper end of the burner D. At a point diametrically opposite the passage I said burner is provided with a vertical passage K, extending downward therefrom, which has its lower end extended horizontally and diametrically into the longitudinal central vertical gas-chamber 7c in the burner. This chamber 76 is made by drilling a smaller hole into the body of the burner below the c0mbustion-chamber and in alinement there- 3 of the tip and keeps the same clean.

with, and it extends from a point preferably below the plane of the arms E and F up into said central combustion-chamber. The upper end of the gas-chamber 7a is closed by the tip m up through a very small central orifice in which the gas is forced into the combustionchamber L. Seated in the lower portion of the chamber K is a cylindrical piston n of such length that when at the limit of its downward movement the discharge-opening of the passage k will be uncovered. This piston has extending centrally from the apex of its upper conical end a needle 0, which as said piston moves to the limits of its upward throw projects through the central discharge-orifice This piston n has one side thereof facing the arm F of the burner flattened in a plane transverse to the axis of said arm, and about the center of length of this flattened portion it is provided with a transverse recess '1", which'is en- -gaged by the eccentrically-located stud R, extending from the adjacent end of the transverse shaft S, which latter is journaled in to assist in the volatilizing of the gasolene therein.

the bore of arm F and has its outer reduced end extend out through a suitable packingchamber in the end of said arm and through a suitable gland-nut T and is provided with a suitable milled wheel m on its outer end with which to turn the same. When this wheel as is in the position shown in Fig. 3, the piston will be at the lower limit of its movement and by giving said wheel a half turn or revolution limit of its upward movement. This recipfirst started, and likewise the heat transmitted to the burner by the burning of the gas from the et to be imparted to pipe (i into the tank By placing the tank A endwise, as hereinbefore described and shown, the light from the burner is not obstructed to the extent it .would be were the flattened sides of the tank in a horizontal position, and a much greater area below said lamp is made light than is now possible.

What I claim as new is- 1. A gasolene-lamp comprising a suitable .burner having a straight body from the tank of said lamp to the upper end of the same; a

longitudinal central gas-chamber; a combustion-chamber; a sinuous passage from the tank to said gas-chamber on the exterior of said combustion-chamber; a valve controlling the inlet portion thereof; a heating-chamber consisting of an annular enlargement of said passage mediate said valve and gas-chamber,

surrounding the upper portion of the walls of the combustion-chamber; in combination with a longitudinally-movable piston in said gaschamber; a needle secured in and extending from the upper end thereof, adapted to penetrate the discharge-orifice in the end of the same farthest from said tank; and means for actuating said piston.
