VAPOR PAINT-BURNER SPECIFICATION forming part; of Letters Patent No. 391,745, dated October 23, 1888.

Application filed July 14, 1887. Serial No. 211,316. (No model.)

To ctZZ whom it may concern..-

Be it known that I, MARTIN L. HULL, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and Improved Vapor Paint-Burner, of which the following is a specification.

The subject of my said invention is a hand lamp for generating-and burning vapor from gasoline and other light hydrocarbons. The apparatus consists of a reservoir, a conducting-pipe extending upwardly from the lower part thereof, a generatingburner on the upper end of the said pipe provided with a suitable regulatingvalve, and a hollow handle on the reservoir, by which the apparatus is lifted, held, and used, made of rubber or like elastic material, communicating with the reservoir at top and provided with suitable checkvalves, so that by squeezing the said handle pressure of air will be produced within the reservoir in order to force gasoline therefrom to any necessary extent.

The improvements particularly relate, first, to the combination, with a vapor-burner or gcneratinglamp, of an elastic lifting-handle for producing pressure in the reservoir to supply the generating-burner; second, to the combination, with the reservoir, of an elastic lifting-handle and a shield therefor, which may be used, if desired, to afford a rigid grasp for the hand and better control of the apparatus, and, third, to an improved construction of burner proper cast integrally, as hereinafter described.

In the accompanying drawings, Figure I is a perspective view of the apparatus. Fig. II is a vertical section of the same.

The reservoirl is formed with a filling-opening for supplying it with gasoline, and is pro vided with a plug, 2, closing the opening, and a pipe, 3,-communicating with its lower part and extending upward above its top. On the upper end of the pipe 3 the burner 4 is screwed. This is cast integrally of brass or other metal, and consists of a vertical neck, 5, an inclined conduit, 6, vertical duct 7, inclined valvesocket 8, and the mixing-cylinder 9,forming the inner walls of the conduit and duct, into which the vapor is delivered through a nipple, 10, and within which it mingles with air admitted through apertures 11 in the sides of the cylinder. The cylinder is also inclined, so as to be in line with the valve-socket and parallel with the conduit, and formed with a rear opening, through which access can be had to the nipple 10. The valve-socket 8 is threaded to receivea screw-rod, 12, the extremity of which forms a. valve to regulate or stop the flow through the nipple 10. On the rear end of this valverod is fixed a hand-wheel, 13, for turning it. A check-nut, 14, on the said rod prevents it being screwed in too far. At the lower end of the mixing-cylinder 9 is a small aperture, 15, to permit a drip of gasoline from the nipple 10 into the customary annular cup, 16, which is fixed beneath the heel of the burner for use in the initial heating of the latter.

The lifting-handle 17 is composed of a rubber tube, 17, secured tightly at top and bottom to brackets 18 19, projecting from the reservoir. The upper bracket, 18, is made tubular to form an air-connection with the top of the reservoir, being connected with the interior of the handle. This bracket 18 has an arm, 21, and is formed with an upwardly-extending duct, 20, a port, 20, leading upwardly therefrom, and an angular duct, 21, extending downwardly parallel with the port and laterally through the arm.

22 is a cap secured to the bracket covering the port and inlet to the duct 21., forming a connecting-chamber, 22.

The port 20 is provided with a check-valve, 23, by which it is controlled to prevent the reflux of air.

A check-valve, 24, opening inward, guards a port, 19, in the bracket 19 at the bottom of the handle for the inlet of air. At the back of the handle is a shield, 25, of thin sheet metal attached to the brackets 18 19 by screws 26, so that said shield may be readily taken off, if necessary, to renew the elastic rubber tube. By using rubber tubing of sufficient stiffness for the handle the sheet-metal shield 25 may be dispensed with; but it is generally useful to afford a more stable hold and give better control of the apparatus.

The operation of the apparatus will be clear By squeezing the from the above description.

ICO

rubber portion of the handle air is forced into the reservoir, producing pressure therein, which forces gasoline up the pipe 3 and causes its ejection in liquid or gaseous form,as the case may be, at the nipple 10. On relieving the pressure the check-valve 23 closes and the atmospheric pressure raises the inlet'valve 24 and fills the handle with air. The gasoline running down into the annular cup 16 is ignited to start the generating-burner in the usual way, and after this a few quick motions of pressure on the handle will force a long blue flame from the front of the burner, the vapor being thoroughly mixed with air entering through the apertures 11 and the flame being spread by cross-bars 27 within the cylinder 9, to cause more complete combustion. These cross-bars likewise assist in conveying heat from the flame to the burner for the generation of gas.

The apparatus constitutes a very effective and convenient paint-burner, being held and operated by the left hand,while the scraper is held in the right. It is also very useful for lighting vapor street-lamps and other vaporlamps. It is also used with good effect by plumbers and tinners for heating solderingirons, and is applicable to many useful purposes.
