To afZZ whom t may concer-n,.-

Be it known that I, ATHOL B. MAOKLIN, a subject ofthe King of GreatV Britain, and a resident of Brooklyn, in the county of Kings i and State of New York, have invented certain new and useful. Improvements `in Hydrocarbon-Vapor-Burning Apparatus, of which the following is a specification.

.My invention relates to an improvement on the construction of my hydrocarbon-vaporburning apparatus shown in Letters Patent Y No.` 707,517, dated August 19, 1902.

` My present invention differs from the construction of` apparatus shown, described, and claimed in the said Letters Patent in that the bell-shaped mixing or cominingling chamber isremoved from itsposition between the burners to a place at a lower elevation within the body of the burner, thus securing the advantage of a less oircuitouspassage for the vapor and air, a direct feed to the burner, a good mixture of vapor and air, and greater pressure against the mantles, with a corresponding increase in the brilliancyY of the light produced. In the position formerly occupied by the mixing or commingling chamber I place an upper vaporizer or distiller, which is heated by the mantles. `In the regular vaporizer I insert a coiled cylinder of wiregauze wound without a mandrel, and in the upper end of the tube of this vaporizer'or immediately resting on the top of the gauze cylinderIplace al disk or washer of dine-mesh wire-gauze and above this another dislcof gauze ofstill liner mesh to serve as a inal screen about half-way up the vapor-nipple. The upper vaporizer is providedwith aBunJ sen burner as well as the lower vaporizer and is connected with the gas-tube of the lower vaporizer,`the gas-tube being provided with a two-way valve having a handle providing means whereby both Bunsen burners are opened and closed simultaneously. The lower vaporizer is provided with a peculiar construction of valve for controlling the flow of vapor thereto from the Outlet-pipe of the upper vaporizer. The vapor-nipple is also raised three-eighths of an inch out of the intenseheat of the auxiliary dame by increasing the height ofthe hub upon which it is mounted, and I` find that a decided gain is accomplished.

.Other novel features in the details of construction have been included in the present invention, as hereinafter described.

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure I is in part afront elevation and in part aver-tical section of my improved hydrocarbon-vapor-burning apparatus having a double burner. Fig. II is a side elevation thereof. Fig. III is in part a front elevation and in part a vertical section of my improved hydrocarbon-vapor-burning apparatus having a single burner. Fig. IV is a side elevation of the same. Fig. V is a detail vertical section of the auxiliary or lower burner and adjacent parts shown in Fig. I. Fig. VI is a vertical longitudinal section throughthe gassupply pipe shown in Fig. II. Fig. VII is a vertical section of the gas-valve shown in Fig. IV; Fig. VIII is a detail view of the sleeve for supporting the cleaner needle-bar, showing the stepped slot in which the arm of the needle-bar is moved.

1 is the lower section, and 2 the upper secltion, of a circular main-burner body shouldered together and providing a mixing or commin gling chamber 3 for the vapor and air. The upper section 2' is formed in one piece with burner tubes or branches 2"', having burners 2b provided fwith gauze burner-caps 4, with a pendent dedector 2, located over the mixing-chamber 3, and with a central boss 2d, surinounting the pendent deflector and positioned between'the burner-tubes and having arim 2u and a vertical socket or recess 2f.

represents posts extending laterally frome the sides of the burner-tubes, inwhich are adjustably secured rods 6 by means of binding-screws 7. hooked upperends 6, from which are suspended the mantles 8, which overhang and surround the burners.

On the central projection 2 I mount an upper vaporizer or distiller adapted to be heated by the burners and mantles owing to their close proximity thereto. This upper vaporizer consists of an outer tube 9, closed at its upper end by a screw plug or cap 10 and at its lower end is provided with a .terminal The rods 6 areprovilded withl ICO which is removably secured bya set-screw or bolt 12, working through the rim 2C. The terminal is also formed with a side fuel or oil duct or passage 11C, a central vapor duct or passage 11 and ascrew-socket 11, surrounding the upper end ot' the central vapor-duct, in which is supported, by its screw-threaded lower end, an inner tube 13, extending to a point near the upper end of the outer tube `9,

producing with the cylinder a vaporizingchamber 14. Surrounding the top of the inner tube 13, between the exit of the Vaporizing-chamber 14 and the inlet to the inner tube 13, is a gauze cylinder 15 for iiltering the vapor passing therethrough and collecting the carbon therefrom.

Connected with the side fuel or oil duct or passage 11c is the fuel or oil supply pipe 16. The vapor produced in the upper vaporizer flows through the central vapor duct or passage 11l1 to an outlet vapor-pipe 17, extending downwardly to a lower vaporizer, in which the vapor is superheated. 13 is a central airtube located beneath the pendent deflecton 2c within the mixing-chamber and extending through the lower section 1 of the mainburner body and screw-threaded thereto, so as to be adjustable therein with relation to the y vapor-nipple 30 beneath and the pendent deiiector above the central air-tube. Secured by their upper tinned ends to the lower secy tion 1 of the main-burner body are dependinggas tubes'or bleeders 19, through which gas vin the mixil'lg-chamber is drawn downwardly and whose lower tinned ends are secured to the upper section of an auxiliary or lower burner body having an annular exte-rior shoulder 20, on which is supported a lower burner body, having an annular interior fiange 23, providing a central air-openin g 23b and a seat 23C and having screw-threaded connection with the upper section 20.

The lower vaporizer is constructed with a vertical tube 24, secured at its upper end within the shouldered central hub 20C in any suitable manner.

The lower end of this tube is closed by a terminal formed with an upper y part 25, screw-threaded to the tube 24 and" having a central vapor ductor passage 25, a middle part 26 of wrench-nut form, having a central vapor duct or passage 26 and a iiarv ing-seat 2b'b and a lower part 27, in which is located a cylindrical head 23, having a central vapor duct or passage 2S, with which the lower end of the vapor-pipe 17 is connected; a tapering upper end 28, fitting in the iiaringseat 2Gb, and a concavity 23c in its lower end, against which impinges a screw-threaded plug 29, working through the lower part 27 of the terminal and whereby the cylindrical head is removably but tightly seated. Fitting within the extension 20 of the central hub 20c of the upper section 20 is a stepped vapor-nipple 30, screw-threaded into and supported by the tube 24 against the upper annular shoulder 20. This vapor-nipple has an extension 30, projecting above the hub extension 20 and above the cup-deilector 21 to isolate the exit of the nipple from the intense heat of the lower-burner flame.

31 is a filling formed of a coiled wire-gauze sheet located with in and surrounding the central vapor-duct 25 of the plug 25, and supported on the filling against the vapor-nipple is a iinegauze filtering-disk 32, while the outlet of the vapor-nipple beneath its upperstep is further guarded by a finer-gauze disk 33, fitted there against. terior seat 23, above the flange 23, within the heating-chamber 22, and fitting at its upper edge against the lower interior shoulder 20b and the central hub 20, is a truste-conical wire-gauze screen 34, through which the combined vapor and air or gas passes from the pendent tubes or bleeders 19 to the heatingchamber 22, toward the outer chamber 23l. 35 is a pillar or rod whereby the main and auxiliaryburner bodies are rigidly connected to relieve the pendent tubes of the weight of the auxiliary-burner body.

36 is a pendent ordinary gas-supply pipe which may be connected with a city gas-main conveying illuminating-gas thereto, having a coupling 37, to which the apparatus is rigidly clamped by means of a supporting-arm 38 on the main-burner body, a clamp-plate 39, and screw or bolt 40. The coupling is formed with a valve-casing 41, having a plug-valve 42, provided with two ports or ways 42 42b and turned by means of a handle 43, having provision for the attachment of a flexible connection 44, whereby the handle is operated. Controlled by the valve is an upper gas-nipple 45 and lower gas-tube 46, connected with upper and lower Bunsen burners 47 4S, respectively adapted to operate in the vicinity of the upper vaporizer and the lower vaporizer, respectively.

49 and 50 are upper and lower pilot-burners located in the gas-pipe and lo ver gas-.tube and playing on the upper and lower vaporizers, respectively. Also extending from the main-burner body is a bracket 51, located at right 4angles to the supporting-arm of the apparatus, having clamp-jaws 52 53, controlled by a clamp-screw 54 and supporting a sleeve 55, having a stepped slot 55, formed with a seat 55", vertical open part 55C, and vertical blind part 55 In the sleeve is mounted the needle-bar 56, similar to that described in my Supported on the inl 59,secured by a set-screw 60 to the curved arm. Referring to Figs. III and IV, I show a modiication of my apparatus in which my improvements are applied to a hydrocarbonvaporburning apparatus having a `single burner. Parts corresponding to those shown in Figs. I and II are similarly lettered in Figs. l is the lower section, and 2,' the upper section, of a cylindrical upper or main burner body, which are shouldered together, the upper section having a gauze burner-cap 4l. The upper vaporizer is provided with a terminal at its lower end, in which the Vouter vapor duct orfpassage'lld extends vertically therethrough. The lower-burner body is constructed with a cylindrical upper section in one piece with a UA shaped bridge 35, which is also in one piece with and supports it from the 'lower section of the main or upper burner body. The lower section 23 of the lower-burner body is formed with an annular chamber 23, having perforations 23" in its inner wall and its outer wall connected with a i lower Bunse-n burner 48, which is in turn connected in horizontal position with a vertical gas-pipe 4-6.` The lower vaporizeris provided with a lower terminal having an upper part 25, formed with a central vapor duct or passage 25, a lower part 26', of wrench-nut form, having aright-angle vaporduct or passage 2W' and a horizontal screw-threaded plug 29', connected with the lower part and having a vapor duct or passage 29", with which the vapor-pipe 17 connects. 3G is a pendent ordinarygas-supply pipe on which the apparatus is supported by means of a coupling37, formed on the bridge ,and into thiscouplin g the gas-pipe is screwthreaded, while the lower end of the coupling is closed bya screw-threaded plug37. 4l isthe valve-casing, connected with the coupling 37', having a cylindrical valve 42 and vertical ducts 42 and 42h', controlled by the valve and leading to a gas-nipple 45 and gaspipe 46', which is connected with the valvecasing. 47 is the' pilot-pipe, connected with the valve-casing. Gl is apendent rod screwed into the bridge 35. The pendent rod is provided with a screw-threaded lower end Gl and iiange (jlb. 62 is'a thumb-nut workin g on the lower end of the rod, and between this thumbnut andthe iiange on the pendent rod I support a globe-ring 63, having a radial slot 63 to enable it to be moved sidewise sufficiently so as to be released when the nut is loosened.

G4 is a screw for securing the globe on its ring.

The pilot for igniting the mantles may be dispensed with, as the upper Bunsen flames serve the purpose.l

'The construction shown in Figs. III and IV is principally intended for large mantles.

The bleeder-tubes are tinned at their ends and are placed in core prints in the sand made toreceive them, and when the molten metal is poured intothe mold the ends unite with the main casting by fusion, making a very substantial, neat,and economical job. These tubes were formerly inserted bythreads at one end and by swaging at the other; but in practice they were likely to work loose, particularly as they were the only support of the upper part of the lamp.

Experiment has shown that the cup deiector, to prevent the gases of combustion from the auxiliary flame from entering the mixing-tube, gives better results if inverted, as shown, with the concave side uppermost.
