ACETYLENE-GAS BURNER.

SPECIFICATION forming part of Letters Patent No. 635,532, dated October 24, 1899.

Application filed March 22, 1899 Serial No. 710,068. (No model.)

To ctZZ whom it may concern:

Be it known that I, FRANK O. FAXON, a citizen of the United States, residing at the city and in the county of San Francisco and State of California, have invented certain new and useful Improvements in Acetylene- Gas Burners; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to certain new and useful improvements in burners for use in connection with acetylene gas; and it consists in the arrangement of parts and details of construction, as will be hereinafter fully set forth in the drawings and described and pointed out in the specification.

The objects of the present invention are, first, to'dispense with the use of the lava burners ordinarily employed in connection with the burning of acetylene gas in order to avoid the clogging and smoking which result by reason of the absorption by said burners of the oil carried by the gasv passing therethrough, and, secondly, to so arrange the burner that a mixing-chamber is obtained which permits of a better air-draft being socured and a more perfect admixture of air than by the use of the lava burner, thus providing for the production of a whiter and more brilliant flame with less carbonization than is obtained by the use of the burners now in use. These objects are attained by forming within the burner-arms air-admixing chambers having air inlet openings therein and having restricted outlet-openings for the mixed gas and air, the restricted outlet-opening for the escape of the gas serving to create agreater draftor suction of air into the mixing-chamber during the escape of gas therethrough, and consequently a more perfeetadmixture of gas and air is obtained, from which whiter and more brilliant flame results. Where the admixture of the gas and air takes place within the mixing-chamber of the metallic burner-arms, there is no absorption of the oil carried by the gas into the small orifice of the nozzle plate ordisk,which acts as abrake to the gas, and hence no clogging or carbonization takes place therein, as is the case with the lava burners made use of, the disk or nozzle plate being made of metal or other non absorbing substance and sepa rated from the lower end of the lava tip or burner by the mixing-chamber, and there is no danger of the outlet-orifice or gas-passage through the said outlet nozzle or disk be coming clogged. This takes place where the opening through the lava tip or burner constitutes the restricted outlet for the gas or, in other words, when there is no separation between the lower end of the burner-tip and the mixing-chamberby a nozzle plate or disk having a restricted outletopening.

The invention also consists in removably connecting the bu rner-arms carrying the mixing-chambers with their supporting-post in order that the said arms may be adjustable for the purpose of readily securing alinement of the gas-jets in order to secure proper alinement and cause the jets to impinge perfectly.

In order to comprehend the invention, reference must be had to the accompanying sheet of drawings, forming a part of the present application, wherein Figure l is a front view in elevation of the burner, partly in section. Fig. 2 is an enlarged top plan view of one of the burnerarms with its tip removed, showing the inner nozzle plate or disk; and Fig. 3 is a crosssectional enlarged detail side view in elevation of the nozzle plate or disk.

In the drawings the letter A isused to indicate the pillar of the burner, and A the support for the burner-arms. 111 the present case the support is provided with a screwthreaded portion a, which screws into the screw-threaded end ct of the pillar, thus making the parts removable. By so doing I am enabled to unite or remove the support A from the pillar A without disturbing the gas globe or shade, thus facilitating the work of handling the parts. The support A is formed with the branch arms B, each of, which supports a burner-arm B. These parts are united by a socket -joint 1). Consequently each burner-arm may be removed or adjusted upon its support independent of the other burnerarm. Eachburner-armisformedwithanangle extension B both of which incline toward each other when the burner-arms are in proper position. IVithin each angle extension of the burner-arms is formed an enlarged chamber 12, which receive the gas discharged from the passage-way W. The full volume of gas passing through said passage-way is prevented from flowing into the chamber 1) by means of the 'metallic nozzle plate or disk 0, fitted snugly within each chamber 1), so as to close or shut down the passage-way b Said nozzle plate or disk. is formed with a minute es- IO cape-opening cl, through which the gas under pressure is forced into the chamber 1). This enlarged chamber 5, formed in each supporting-arm, constitutes the mixing-chamber for the air and gas, the air being drawn therein through the air-inlet openings cl, formed in each burner-arm above the nozzle plate or disk.

In the upper end of each burner-arm is fitted a flat lava tip D, having an escapeopening d therethrough. I/Vhile this escape outlet-opening d is considerably larger than the opening cl of the nozzle plate or disk 0, it is nevertheless many times less than the diameter of the mixing-chamber Z). Consequently the outlet for said chamber may be said to be a contracted one. This contrac tion or reduction of the outlet area of the mixing-chamber gives a greater force to the ejected streams or jets of gas and causes a stronger draft to the mixing-chambers, thereby causing a greater quantity of air to be drawn into the said mixin g-chambers through the air-inlet openings cl and obtaining a better admixture of gas and air therein, which 5 results in obtainingawhiter or more brilliant flame and less carbonization than with the lava burners now used in connection with the burning of acetylene gas.

Inasmuch as the thin metallic nozzle plates 4c 0r disks arranged within the mixing-chambers will not absorb any of the oil contained within the gas flowing therethrough, clogging and smoking, which result therefrom, are obviated.

The jets of gas ejected through the burnertips meet at a common point and form the usual fan-shaped flame. However, by making each burner-arm adjustable to its seat either arm may be adjusted so as to secure perfect alinement of the jets. This is quite an important feature, as it facilitates the adjustment of the burners and enables me to secure perfect alinement of the jets.

Having thus described my invention, What I claim as new, and desire to secure protection in by Letters Patent, is-- 1. In a burner for acetylene gas, the combination with the burner-arms having extensions inclining toward each other, of gas pas- 6o sage-ways formed in said burner-arms, an enlarged mixing-chamber formed in each eXtension and with which the gas passage-ways communicate, air-inlet openings communicating with the mixing-chambers, a nozzle-plate having a minute outlet-opening fitted in each mixing-chamber so as to cover the gas passage-way, and of a burner-tip fitted in the upper end of each burner-arm.

2. In a burner for acetylene gas, the combination with the burner-arms inclining toward each other, of an enlarged mixing-chamber formed in the upper portion of each arm, airinlet openings formed in the walls of said chambers, a gas passage-way in each arm and communicating with its mixing-chamber, a nozzle-plate provided with a minute outletopening fitted in each chamber so as to cover the gas passage-way, and of a burner-tip secured in the end of each burner-arm, said tip having an escapeopening therein.

3. The combination with a burner-arm of a burner for acetylene gas, of a gas passage-way therein, an enlarged mixing-chamber with which said passage-way communicates, a nozzle-plate having a minute outlet-opening removably secured within the mixing-chamber so as to cover the gas passage-way, an airopening in the wall of said chamber, and of a burner-tip removably secured in the upper end of the burner-arm, said tip having a gasoutlet opening therein.

4. In a burner for acetylene gas, the combination with the support, of the burner-arms removably and adj ustably secured thereto, a gas passage-way formed in each, an enlarged mixing-chamber formed in each burner-arm, air-inlet openings in the wall of said chambers, a nozzle-plate having a minute outletopening removably fitted in each mixingchamber so as to cover the gas passage-way, and of a burner-tip having an escape-opening secured in the upper end of each burner-arm.

5. In a burner for acetylene gas, the combination with the pillar, of a support removably secured thereto, the burner-arms adjustably connected to said support, an enlarged mixing-chamber in each burner-arm, a nozzleplate having a minute escape-opening fitted in each mixing-chamber, an air-inlet opening in the wall of each chamber, and of a burnertip fitted in the upper end of each burner-arm, said tips having an outlet-opening therein through which the gas from the mixing-chamber escapes.

6. The combination in an acetylene-gas burner, of two burner-arms mounted upon a suitable support and inclined toward each other, each bu rner-arm being provided with an enlarged mixing-chamber having a minute gas-inlet opening in the base thereof, and airinlet openings through the wall thereof, and of a burner-tip removably fitted in the upper end of each burner-arm and having a gas-outlet opening, said tip forming the cover or top for the enlarged mixing-chamber.

In testimony whereof I hereunto affix my signature, in presence of two witnesses, this 16th day of March, 1899.
