THOMAS POYSER, OF SAN FRANCISCO, CALIFORNIA.

PAlNT-BREAMER.

SPECIFICATION forming part of Letters Patent No. 324,163, dated August 11, 1885.

' Application filed July 25, was.

- To all whom it may concern.-

Be it known that I, THOMAS POYSER, a citizen of the United States, residing in the city and county of San Francisco, and State of California, have invented a new and useful Improvement in Self-Acting Blow-Pipe Lamp and Paint-Burner, of which the following is a specification.

My invention relates to improvements in blow-pipe lamps in which the gas is generated by heat created bya heated rod connecting with a gas-chamber in the interior of the can holding the general supply of camphine, alcohol, benzine, or other gas-generating substance. It will be more fully understood by reference to the accompanying drawings, in which-'- Figure l is a perspective view of the lamp with a portion of the draft-chimney cut out. Fig. 2 is a cross-section cut vertically through the center of the same. Fig. 3 is a plan view. Fig. 4 is a perspective of the gas-generating and flame and heat regulating gage-rod. Fig. 5 is a cross'section of the lamp, showing the wick-tube when placed in the center of the can, and the tube bent to take up the fluid when but little remains in the can, and is a substitute for the straight tube placed. at the side of the can, as shown in Figs. 1 and 2.

The following is the construction of the same:

A represents a tight vessel or can; B, the wick-tube or chimney; C, the cap of the wicktube; E, thecombustion-chamber; G, the gasgenerating and flame and heat regulating gagerod.

H is the opening for filling the can.

J represents the gas-tube, which in Fig. 2 is shown as being straight,while in Fig. 5 it is shown curved at its lower end.

L represents the regulating groove or slot in the rod G. The rod is sometimes constructed with the extension M, and generally so where no wick is employed, as shown in Figs. 2 and 5.

O represents the draft-opening or air sup ply.

The form of the can, wick-tube, and combustion-chamber is the same as that employed in my improvement patented b01116 under date of May 2,1882, and numbered 257 ,380.

(No model.)

- I employ the rod Gto generate gas and regulate the amount of flame and heat.

The following is the operation of the same: The can being filled with any suitable burning fluid, when there is a wick the fluid is drawn up, and passing out through the groove L, may be lighted, but'where there is no wick the can is sufficiently inverted and the rod G turned out or unscrewed sufficiently to allow a little of the fluid to pass out through the slot L, and when lighted the rod G is quickly heated and gas is formed in the gas-tube J or K, and as soon as the can is righted, the gas flows out, creating more intense heat and heating the rod still more. When gas is so rapidly generated in the gas-chamber, and the pressure so increased in the can as to require regulation, the same is effected by screwing the rod G down into the cap 0, and partially closing the opening formed by the slot L. This slot L is generally filed with a three-cornered file, tapering from the bottom until it runs out as shown in the drawings. By this arrangement the amount of heat and flame can be perfectly regulated by placing a wrench upon the nipple N and turning the rod G out or in, thus opening or closing the slot L.

WVhen the can is constructed with the tube in the center, then the bent tube must be employed, where there is no wick employed to take up the fluid, as the gas is liable to blow out and allow the cooling of the heater when the supply of the fluid is not kept in contact with the heated parts.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

The combination, with a can having the wick-tube B, provided with the cap C. of the chamber E, inclosing the upper end of said cap and having openings D, the gas-tube J, separably connected with the wick-tube, the rod G, having the groove L, threaded, as shown, said rod being located within the tube J and extending into the chamber E, and a filling-opening, substantially as set forth.

THOMAS POYSER.
