No. 13993.—12th September, 1901.—THE ATLANTIC ACETYLENE BURNER COMPANY, a corporation duly organized under the laws of the State of New Jersey, and having its principal place of business at 15, Exchange Place, Jersey City, United States of America (assignees of John Harris, of 222, Seventh Street, Buffalo, United States of America, Mechanic). Improvements in gas-burners.

Extract from Specification.—The improved burner comprises an upright gas-receiving tube a that forms the lower end of the device. The tube a has its lower end screw-threaded internally to render it capable of being screwed on to a gas-supply pipe (not shown). The tube a has its upper end screw-threaded externally and screwed into the correspondingly internally screw-threaded lower end of an upright air-receiving tube b. The tube a is provided with an external flange a¹ that abuts the lower end of the tube b. The flange a¹ is polygonal externally to accommodate the application of a wrench thereto. The tube a has its upper end terminating in a cone 6, and the gas-conducting or gas-supply passage-way 7, that is formed within the tube a, is gradually reduced in width or transverse area toward the upper extremity or apex of the cone 6 where the said passage-way terminates in a discharge-orifice 8 that is formed centrally of the said apex. The cone 6 forms the bottom of an air-receiving chamber 9 formed within the tube b next above the tube a. The surrounding wall of the chamber 9 is provided with a series of lateral perforations or air-inlets 10 that are arranged at the same or approximately same horizontal plane at suitable intervals around the tube b. The tube b illustrated has four uniform air-inlets 10 arranged equidistant apart, and the arrangement of the parts is preferably such that the said air-inlets 10 shall be arranged directly opposite the gas-discharge orifice 8 of the tube a so as to conduct air from the external atmosphere directly to and in advance of the said orifice, and preferably the said perforations 10 are large enough to render them capable of directly conducting air against the aforesaid cone 6, and the cone is instrumental in directing the air toward the aforesaid orifice. The tube b, a short distance above the air-inlets 10, is provided with an annular shoulder 11 that forms a seat for the dish-shaped holder c that is instrumental in supporting the chimney, globe, or glass d that surrounds the burner in the usual manner. The holder c performs also the function of supporting the device employed in suspending or holding the mantle e, or other body, that is to be rendered incandescent over the upper and flame-discharging end of the burner. A vertically arranged port or passage-way 12 is formed in and centrally of the top wall of the air-receiving chamber 9, and has its lower end gradually enlarged downwardly—that is, the surrounding wall of the lower end of the port or passage-way 12 flares downwardly, and thereby facilitates conducting or directing the gas and air entering the chamber 9 during the operation of the burner upwardly into the said port or passage-way, and the gas and the air are brought into closer communication with the said port or passage-way. The port or passage-way 12 has its upper end discharging into a chamber 13 formed within a tube f that has its lower end screw-threaded internally and screwed on to corresponding threads formed upon and externally of the tube b next above the bottom of the holder c. The tube f is screwed on to the tube b far enough to cause the tube f to clamp the holder c against the seat forming shoulder 11 of the tube b. The tube b has its upper end preferably considerably smaller in cross-section than the surrounding tube f, so as to form an annular space 14 externally of the upper end of the tube b between the external surface of the tube b and the internal surface of the tube f. The said space 14 forms a downward extension of the chamber 13. The gas and air that are brought into close communication with each other within the port 12, as already indicated, are thoroughly mixed within the chamber 13, and the downward extension of the said chamber around the upper end portion of the tube b forms a pocket from which the mixture cannot escape except upwardly to the upper or gas-burning end of the burner. The tube f is provided internally at the upper end of the mixing chamber 13 with a screen g that is arranged horizontally and transversely of the tube and held in place upwardly against an annular shoulder 15 formed internally of the tube f by any suitable means, such, for instance, as a split spring-forming ring h introduced into and against the underside of the screen. The tube f has its upper end, above the mixing chamber and above the screen g, reduced in cross-section to form a vertically arranged port or outlet 16 centrally of the upper end of the tube f above the screen. The port 16 has its lower end gradually enlarged towards the screen g, so that the surrounding wall 17 of the lower end of the port 16 flares toward and overhangs the screen. The port 16 is reduced in size at its upper or outer extremity so as to form an annular downwardly or inwardly facing flange 18 internally of and upon the surrounding wall of the outer and discharging end of the said port, which flange, preferably, has its under or inner side flaring downwardly or inwardly. The enlargement of the port 16, next above the screen, accommodates the passage of a larger volume of the inflammable mixture through the said screen than would be the case in the absence of the said enlargement of the said port. The reduction or contraction of the port 16, at its outer or discharging extremity, is instrumental in preventing the flame from entering the burner during the operation of the burner.

[NOTE.—The number and length of the claims in this case preclude them from being printed, and the foregoing extract from the specification is inserted instead.]
