SEE-GIFICATION forming part of Letters Patent No. 685,939, dated November 5, 1901.

Application iiledrOctober 17, 1899. Serial No. 733,871. (No modell) To all whom, it may concern:

Beit known that we, GUIDO PALAZZI, UGO PALAZZI, and VITTORIO PIVETTA, subjects of the King of Italy, residing at the city of Naples, in the Kingdom of Italy, have invented certain new and useful Improvements in Hyp thereto, a closed vaporizingfchamber above y the heating-burner, a soldering-burner in communication with a second gas conduit or pipe, a gassupply pipe in communication with the gas conduits or pipes, a vapor-blowpipe in communication at one end with the upper part of the vaporiZer and at the other with the soldering-burner, and a spring-valve for regulating the flow of gas opened by finger-pressure, located in each of the gas-pipes leading to the burners.

Such invention is fully shown in the following specification, of which the accompanying drawings form a part, wherein similar letters I of reference designate like or equivalent'parts i wherever found throughout the several views, and in which-- Figure l is a side View of the apparatus. Fig. 2 is a top View thereof. Fig. 3 is a vertical sectional View of the same on the line X X of Fig. 2. Fig. 4t is a sectional View in detail, on an enlarged scale, of the valves on the line Y Y of Fig. 2.

Referring to the drawings, the referenceletter ct indicates the handle of the solderer, and through its hollow interior passes the gaspipe b. This pipe divides into two branches where it leaves the handle and immediately before the main valves c d. The valve d is placed in the lower pipe e and the Valve c in the upper pipe, which beyond such valve `o also divides into two parallel branches g g,

which each communicate at the front of the apparatus with a single pipe 72., which is bent downward, so as to give a convenient direc- .2 tion to the iiame, the burner 7c being located at the end thereof.

The regulatingvalves c and CZ consist of a piston S, having annular gas-grooves u and o, which pistons are forced outward by a spiral spring T and inward by finger-pressure exerted upon the head or nger pieces. The two valves differ in that in its normal position the valve c fully closes its conduit or pipe, so as to absolutely stop the flow of gas therethrough, while the valve CZ in this position allows a little passage to remain always open to the gas-stream in the pipe or conduit e, the groove o being arranged in such a way that a small portion of it always forms a free communication between the conduit or pipe e and its branch of thepipe b.

The pipe e extends to the front of the apparatus and turns down in a hookf, by which the device may be hung up. At about the middle of the pipe e and immediately under the water-reservoir q is a burner or burners m. The pipe e ends in a finely-pointed tube or pipe n, which runs along the tube 7e and terminates with a very small hole under the burner lo, acting as a pilot-light therefor.

Inside 4the tube h or pipe is another smaller pipe or tube p, with open ends terminating in the interior of the burner 7c at one end and at the other in the upper part of the small reservoir or boiler q, which forms the vapor or blowing pipe of the device. This boiler is usually of cylindrical form, with rounded ends,having at its upper part an aperture r, with a screwed cover, through which the water or alcohol to be vaporized may be poured.

To operate the device, the reservoir or boiler q is filled about half-full of water or alcohol and the top screw r screwed tightly down, so as to make suoli boiler air-tight, save through the vapor or blowing pipe p. The tube b is then connected to the gas-pipe Figs. 1 and 2, and when the gas-cock has been opened the gas passes through the small passage, which the groove o of the valve ol always leaves free, and iiows from the burner m and from the small pipe n at the burner la, and these being 1 lighted the solderer is ready to be put to use.

To use it, the valve d is pressed inward in IOO such a Way as to bring the groove n in regis-` try With the opening of the conduit or pipe e in order to allow the greatest possible quantity of gas to flow through such pipe eto the burner m, which raises the Water in q to the boiling-point, and as soon as the jet ot' steam flowing from the blowing-pipe p is of sufficient force the valve c is pressed inward until the groove u comes in registry with the opening of its conduit or pipe and allows free passage of the gas through the tubes g and g lo the pipe h, and at the aperture of the burner la the gas meets the pilot-'dame n and is thus lighted, whereupon the apparatus is ready for Working by directing the pencil of flame upon the article to be soldered or heated.

Thejet or pencil of 'flame may be regulated by pressing upon the valves c and CZ.

ofthe burnerm,and consequentlythestronger the blast, and the greater that on d the greater the flame of the burner 7c. j

When the soldering is terminated, the valves c and d are released from finger-pressure, Whereby the flame of the burner 7c is eX- tinguished, and at the same time the flames of the burner m and of the small pilot-light 'n are diminished.
