AUGUST C. ROSENBROOK, OF BROOK, INDIANA.
AUTOMATIC BLOWPIPE.
SPECIFICATION forming part of Letters Patent No. 712,097, dated October 28, 1902.
Application filed April 10, 19Q2.
first vaporized and then at the burner mixed with the desired amount of air to attain perfect combustion and a high degree of heat, my object being to provide a construction for this purpose which is economical in the use I 5 of fuel, durable, and easily managed by unskilled persons, so that it is adapted to a wide range of duty, the same being described hereinafter, and illustrated in the accompanying drawings, in which Figure 1 is a vertical axial section to illustrate general construction, the wicks for delivering liquid fluid to the gas-chambers and a needle-valve being shown in proper position in elevation. Fig. 2 is an axial vertical section of the top portion of the main gaschamber, together with the burner, same as in Fig. 1, but ona scale two and one-half times larger to more clearly show the proper construction and relative position of the parts.
Fig. 3 is a section on broken lineA B, Fig. 2,
looking in the direction indicated by arrow E, to clearly illustrate the openings leading from the main gas-chamber into an interspace between the walls of the burner. Fig. 4 is a cross-section of the burner-nozzle on broken line C D, Fig. 2, to illustrate the annular fuelgas aperture and the central orifice for the delivery of air to the central part of the flame.
Similar numerals indicate like parts throughout the several views.
In this instance the containing vessel 1 is provided with a screw-threaded cap 2,to which is attached a closed-top vertical retort 3, whose lower end opens into the containing vessel.
Transversely through the top portion of the retort 3 is a burner-nozzle,which consists, Fig. 2, of atapered tube 4, fitted gas-tight through the retort and terminating at the small end in a delivery-orifice 5. Within tube 4.1m second tube 6, which is attached to tube 4 by a ring 7, Fig. 2, at the rear end, so that an interspace Sis formed between tubes 4 and 6, the
Serial No. 102,284. (No moan.)
small end of the inner tube 6 being so nearly the same size as the inner diameter of outer tube 4 that the interspace 8 is reduced to a very narrow annular passage-way, as is seen at 9 in Figs. 2and4. There are holes 10 which valve-casing close to the needle-valve, and
the lower end of the wick is in contact with the liquid fuel within tube 13. Secured to the upper end of valve-casing llisa tube 15, filled with a wick or otherliquid absorbent, the tube terminating at the topin a wire-gauze cap 16, and at the side next to retort 3 area number of holes 17 for the escape of gas from the interior of the tube.
In use after the containing vessel is supplied withasuitable fluid, like alcohol or naphtha, the fluid after valve 12 is opened quickly saturates wick 13 and thence through the valve-casing saturates the wick in tube 15, and in the meantime wick 18 is saturated throughout its length when if the gauze burner at 16 is lighted the heat'will quickly vaporize the liquid below the gauze, when it will be ignited at the holes 17, which being close to the retort 3 will heat the upper portion of the latter and vaporize the liquid supplied by wick 18, the vapor finding vent at holes 10, and thence along the interspace 8 will pass out at annular orifice 9 and at orifice 5 be ignited, the outward flow of the vapor serving to induce a central current of air through tube 6, which, mixing with the vapor, results in a very hot flame, which may be regulated in intensity within certain limits by the amount of liquid admitted to tube 15 through valve 12, for it is obvious that after the retort-is once heated a pressure may be easily maintained in the containing vessel and cause the fuel to be forced upwardly through tube 13 and through valve-casing 11,
I claim as my invention 1. In an automatic blowpipe, a closed vessel for liquid fuel, a retort consisting of a tube having one end closed and provided with a gas-outlet burner-nozzle, the other end of the retort attached to and in communication with the vessel, a wick filling the retort and extending out into the vessel, and close to the retort a torch consisting of a tube having one end portion provided with gas-outlet orifices adjacent the retort, the other end of the torchtube attached to a valve-chamber, a tube having one end portion extending from the valvechamber and into the vessel, a passage-way leading through the valve-chamber from the tubes of the torch, a valve guarding the passage-way, and a wick terminating close to the AUGUST 0. ROSENBROOK.
