To all 1:71am it mai comiem:

Be it known that I. Man ox \V. Prrxrn, a citizen of the United States. residing at.

Chicago, in the county of Cook and State of Illinois, have mvented newand useful linprot ements in Lamps, of which the followmg is a specification.

- The, invention relates to an improvement in lamps of the vapor burning type. comprehending specifically a onstruction whereby the lamp is rendered self-generating and the vaporization controlled directly by and in proportion to the. heat from the burners.

T he main object of the present invention is the provision of a generator disposed? within the heat zone from the burners and adaptedto receive the fuel vaporizing heat directly from the lmrners. the disposition of the generator and feed conduitleadingthereto insuring an even and constant llovv of the fuel and astead generation of gas in i suiliirient quantity to'properly supply the Another object. of the. invention is the provision of a feed conduit leading to and I in connmuiication with the generator. and the disposition of this conduit within the heat Zone i'rom-theburners, so that the fuel is initially heated during its passage il'l!'()ii;fll the conduit and prior to its enr burner tubes. Fig. 5 is a vertical section of the grid for the burner tube. Fig. 6 is a perspective view of the coupling for conneciing the hanger tube and burner ring or spider. Fig. 7 is a plan of the globe supporting ring. Fig. 8 is an elevation of the body casting of the lamp. Fig. 9 is a horizontal section partly in elevation illustratin the connection between the generator and valve body. Fig. 10 is a modified form of the body casting,

Referring particularly to the. accon'ipanying, drawings, 1 represents the hanger tube which ma y beof any desired length and is preferably adapted for engagement at the upper end with any desired form of ceiling plate. To the lower end of the hanger tube is secured through an exterior threaded connection a coupl ir preferably of the ordinary sleeve type and formed with a longitudinally disposed slot. 3. opening through I 3 the upper end ofihe coupling and terminatiug" above the lower end thereof, as clearly 7 I shown in Fig. 6. I

A connecting plug 4 15 secured in the lower end of the conpdng 2, preferably through trance into the generator. whereby the \af porization within the generator is materially facilitated and a more uniform gas supply maintained.

Another object of the invention is to;

materially simplify the construct ion and arrangement of the lamp parts, whereby to provide for the convenient and ready assemblage or separation of said parts when desirwl. and thus imnrcconvenient accessibility of the material parts of the lamp when replacement or repair is: necessary.

With these and other material objects in view, the invention consists in certain details of t'fUiin'UiittlOll hich will be fully descriot-d in the following s ieritication, refereat-e being had therein particularly to the in-co'mpanyiug drawings, in which Figuri- I is a \N'tit'nlsectional vicw,partly in elm atiou. of a lamp c nstructtal in accord- :lllttwith my invent ion. Fig. 2 is a transverse section of the same on line 22 of Fig. 1. Fig. 3 is a vertical sectimial view partly in elevation illustrating the connection of the supply pipe and feed tube. Fig. his a bot tom plan of the. delivery end of one ofthe" spider .3.

The relatively outer or free end of each tube (3 is. bent or formed to provide a' depending outlet, which is interiorly' thr 1K1- ed at 7 for the reception of a burner tube 8,

The burner tubes are 01' frusto-conical formation in longitudinal section, being interiorly formed. however with a longitudinally extending bore J of even diaun-ter throughout. The irustoa-onical formation of the burner tube tends to materially thicken the relatively lower portion of the all thereof, fora purpose which will presently appear. At the relatively lower end the bore 2) of the burner tuhe is increased in diameter to form a chamber 10, the lower portion of the wall of which is threaded at 11.

, 112 represents a grid comprising a cylindrical disk of metal of appropriate thickness, the peripheral edge of which is threaded for engagcmentzwith the threads 11 of ,the chamber l0 of the burner tube. The grid 1.2 comprises essentially a centrally disposed solid section 13 exteuding'diametrically of the plug, from which section extend in both directions a series of parallel slots Lt opening through the peripheral edge of the disk. While preferring the pardisk.

allel disposition of the slots 14'. it, is to be understood that they may have any angular arrangement relative to the central section desired, the sole requirement being that the slots open entirely through thebody vof the The lower end of the burner tube/is exteriorly beaded at- 15 to provide for the convenientapplication of a mantle 16, which in ordinary use is adapted to be secured by a suitable connection about the burner tube 1 above the bead.

The relatively lower end of the spider body is interiorly threaded for the reception of the upper end of a mixing tube 17, comprising a length, of tubingterminating above the lower ends of the burner-tubes. The

below the sphere 19. The sphere is formed in the relatively upper portion with a threaded opening 22 for the reception of the lower end of the mixing ube, and in alinemeat with the opening 2:, at a diametrically opposite point with a second opening 23, for a purpose which will presently appear. Intermediate the openings '22 and 23 the wall of the sphere is fdrmed with a series of circulnferentially or otherwise disposed openings 1'4- in which are secured one or thus radiate from the sphere, and may be prolonged the desired distance to carry their open free ends beyond the plane of the burner tubes to insure aj proper supply of oxygen to the sph e.

A "lobe holder support :26 is threaded into the section 21 of the body, said support beingof tube like form and depending below the section 21 the distance requisite to properly support the globe ring 27, which ring or holder, more clearly shown in Fig. 7. comprises a sleeve 28, of a size to encircle the support 26, and interrupted or open at- 2! for a purpose hereinafter described. The sleeve 28 is provided with a set screw 30. whereby the sleeve may be held in adjusted position on the support, said sleeve The casting com-- The tubes 25 being further provided with. radiating arms 31 supporting at their outer' ends a ring 32, surrounding the sleeve 28, and of sectional formation to receive and em ti e the lower edge of the globe. An ornamental band 33 is arranged tosupport the upper end of the globe, said band being secured upon the ends of the air supply tubes 25 through the I medium of flanged hollow plugs 34 threaded in the endsof 'thetubes, as clearly shown in Fig. 1.

The feed conduit of the lamp proper com L prises a section of pipe ilf) within which is ooselyi disposed a feed tube 36, having a comparatively restricted bore. Between the pipe 35 and the tube '36 is disposed a layer of asbestos 37 or other non-conducting mate-' rial, the function of which is to prevent vaporization of theiuel passing through the feed tube 36, while admitting, however, the passage of sufficient heat from-the burners to initially heat the fuel to a degree below vaporizing point.

The feed conduit is secured in the burner in the following manner. The upper. end of the conduit is disposed within the hanger is projected laterally through the slot 3 in the sleeve coupling 2. The conduitwis then passed down between two of the spider tubes tube 1, and below the lower end of said'tube sleeve section 21 thereof and downwardly through the globe holder support, 26, depending below the lower end of the latter, as shown in Fig.

The n'onconducting lining 37 and the feed tube 36 terminate above the lower end of the feed pipe the latter below the feed.

tube being interiorly threaded for the reception of a valve body 38, the u per end of which is reduced in the form 0 a plug for insertion within the feed tube The valveg body isformed with the usual longitudinally extending duct 39, which receives the fuelfrom the feed tube 36, said body being also provided with a cut-oil valve 40 suitably mounted for movement in the body and having its stem projected beyond the body and formed or provided for manual operation.

The valve body is provided with a laterally projecting arm 41 interiorly formed with a channel in comnninication with the duct 39 of the bodysaid channel 42 being at; the free end of the arm 41 turned upwardly, as at 43. and openin through the upper surface of the arm, t e portion 43 no I g a i proper passage of the gasolene, while atthe same time permitting the practically instantaneous disconnection of. the generator from the valve body when desired. In providing f this connection I secure in the lower por- J tion of the generator a :nnion plug 45.

as, in the. position noted, to encircle thearm- 41. Diamctrically opposite the connection of the ring 46 with the plug -15 said ring is formed with a threaded opening 47 to re ceive a threaded push rod 48, the lower end of which is provided witha thumb piece 49 for convenient operation. i

In connecting the generator to the valve body the push rod -18 is withdrawn the desired distance and the ring i6 is passed over the end of the arm -11 until the conical end of the plug 45- approximately registers with the mouth of the channel 43. The rod 48 is then threaded through the opening 47 until-it contacts with the lower surface of the arm-ll. the movement of the rod being continued until the conical end of the plug 45 is seated in the flared mouth of the chant The lower end of the gcn erator is thus secured in a fluid tight manner to the arm of the valve body, the connection providing, however, for practically instantaneousseparation of the parts when desired by withdrawing the rod 48 and lifting upward on the ring 46 to remove the end of the plug from the channel in the arm.

- The generator extends above the arm it in practically parallel relation with the globe holder support 26, being above the sleeve section 21 of the body projected laterally to a slight degree until disposed between the arms 20 of the body. the extreme upper end of the generator being passed through the opening 23 in the sphere 19 and provided with a plug 50 having a restricted outlet 51. As the generator seats loosely in the opening 23, it is obvious that; disconnect-ion of said generator from the arm 41, in the manner previously described, permits the complete removal of the gcnerator in a simple and expeditious manner.

The generator is preferably disposed on the side of the body opposite the feed pipe 35, thereby avoiding interference and providing for the convenient connection of both of these parts with the body.

The lamp is supplied with fuel through a supply pipe 52, preferably in the form of a \vire tube having a comparatively restricted bore. The supply pipe extends within the hanger tube 1 and is connected to the upper end of the feed pipe in the manner shown in Fig. 3. For this purpose -the u per end of the feed pipe is interior-1y threa ed to receive the lower end of a coupling 53, the interior bore ill of which is slightly flared at the upper end, as at 55;

The upper end of the coupling is cxteriorly threaded to receive a lock nut 56, and the lowerend' of the supply pipe is provided with. ajamb 5} to titwithin the flaring end of the bore 5%. With the janib 57 fitting in the bore of the coupling the nut 56 may' be applied to firmly fix the jainb in the mouth of the bore, thereby providing a fuel tight connection which maybe. readily operated to permit separation of the parts when desired. v V

With the parts constructed and assembled as described it will be understood that. the

fuel, as gasolene or the like, will find its through the feed conduit itis to be noted that itwill receive'the heat from the burners of the lamp, so that said fuel is highly heated duringlts travel through this conduit. By virtue of the asbestos lining, however, the fuel is protected against that dereepf heat necessary to vaporize the fuel, it being desirable that the'fuel be delivered to the generator in a liquid state. As the f fuel reaches the generator it is subjected to the heat of this body and vaporized, passin rthrough the outlet port 51 and into the. i e

sp ere 19, the vacuum produced by the travelof the vapor tending to draw air 1 through the tubes 25 to be mixed with the vapor for ignition purposes. Owing to the opposing paths of travel of the vapor and air a complete mixture occurs in the mixing tube 17, from which the mixture passes to the burners and is ignited. The pressure of the gas tends to distend the mantles 16 into proper form, so thatthe resultant incandescent'e' produces a brilliant and steady light. V

It will be noted that the generator 44, as well as the feed conduit is disposed within the heat zone of the burners, so that during the use of. the lamp the generator is main tained at a suflicient degree of heat to com-- pletely vaporize the fuel admitted thereto, and avoid any flooding through improper vaporization.

In Fig. 10 I have shown a modified form oi body casting. wherein the section 21" is projected laterally so that the same is disposed out of alinement with the s here 19'.

3y this means both the feed conduit 35 and the generator 44' may be carried through the .lamp section without requiring the lateral changes and modifications may be resorted to without departing t'roui my invention, and it is to be understood that 1 consider as within the'spirit of the present invention all such changes and modificationsasinay fall within the. scope of the appended claims.
