uids; and it relates more particularly to the` construction and arrangement thereof.

The principal objects of my invention are first, to provide a comparatively simple, durable and efficient vapor burner; second, to

. provide a vapor-burner in Which the naphtha,

gasoline or other hydrocarbon uids are presented adjacent to the base of the burner to the generating chamber thereof, in order to expedite and insurea better vaporization and t-o afford better illuminating effects resulting from a given quantity of fluid utilized in the production of a flame at the exposed end of the burner in the presence of a mixing cham` ber; third, to provide a vapor burner with a laterally adjustable curved detlector plate for spreading the ilame and with an air shield and mixing chamber connected therewith and located adjacent to a gas generating chamber and the naphtha, gasoline or other hydrocarbon iiuid introduced into said chamber by means of controlled pipe connections from the front of the burner or hottest portion thereof, in order to enhance the character of vapor generated from the fiuid passing therethrough, to reduce Waste and to increase the illuminating properties derived therefrom; fourth, to pro- `vide a vapor-burner in which the several conduits or channels leading to the chamber, the construction being such as to adapt the same to inside and outside purposes. y

Myinvention consists of the improvements in vapor-burners hereinafter described and claimed.

The nature, scope and general features of my invention will be more fully understood from the following description taken in con- 6o nection with the accompanying drawings forming part hereof;` and in which- Figure l, is a perspective view of a vapor burner embodying features of my invention shown in application to a main provided with a globe-shaped Water trap and with means connected therewith -for regulating the supply of fluids to the main and for permitting of the. discharge of water from the trap, the construction and arrangement of the appara- 7o tus therein shown is such that the same is especially adapted for use in street lamps. Fig.

2, is a View in perspective of the burner proper detached from the main supply pipe or connection; and Fig. 3, is a vertical longitudinal section of avapor burner embodying features of my invention and adapted for the reception of a shade or globe for inside lighting purposes.

Referring to the drawings a, is a main sup- 8o ply pipe having detachably connected therewith a globe shaped Watertrap and fluid regulator B, provided with a stop-cock b', and with a blow-off valve or cook b2, having a cuto key b3. The section a', of the fluid supply 8 5 pipe a, is adapted for the reception of a Wicking a2.

C, is the vapor-burner provided with an internal longitudinal channel c', and a vertical channel or conduit c2, leading directly to the 9o vaporizing or generating chamber o3, with an internally threaded valve stem socket c4, adapted for the' reception `of the threaded stem of the needle pointed cock d, having a key d. The generating chamber c3, has a contracted vapor nozzle or exit c6, into the interior of which normally engages the tapering end of the cock d. The generating chamber has a depending threaded extension c5, which is adapted for the reception of the roo threaded integral neck d2, of the cupshaped device d3, for containing hydrocarbon fluid or naphtha which is'permitted to escape through the contracted vapor nozzle c6, of the generating chamber c3, into the same, in order that by the igniting of the same`r by radiation they generating chamberL may'g be heated up for vaporizing the fluid escaping or forced into said chamber. i Formed integral with the casting comprising the parts of the burner is a curved bearing plate for the reception of a laterally adjustable curvedy fiame deilector plate c7, provided with Wind or air shields e and e2, bent in such manneras to form a hood and comprising a mixing chamber adjacent to the vapor discharge nozzlel of the generating chamber e3. 4Into one end of the conduits or channels of the casting constituting the burner C, is inserted athreaded plug f, for a f purpose to be presently fully described.

With special 'reference to Fig. l, the flow of the naphtha or other hydrocarbon Huid from a suitable supply is through fhepipe c,

and trap B, under` regulation, which is de-V `tachably connected Withthe sectionof pipe y a', containinga wicking to the burner proper.`

Any kWater carried into the pipe d and trap B, by reason of its specific gravityfalls to the bottom of the trap B, and is discharged through the valve b2, by opening the cock b3. The fluid or naphtha passing through the wicking or analogous ymaterial a2, and regulating the supply of fluid to the generating or vaporizing chamber, passesina curved direction through the `internal conduit c', of the burner proper andby operating'the needle-cock d,by means of its key d', the vapor generated in the rst instance bythe heating up of the chamber c3, is ignited, producing a flame at the exposed yendfof. the contracted orifice c6, of the generating chamber c3." vThe vaporization of the fluid inthe first instance, is obtained by permitting the fluid to flow through the generating chamber and to escape through the contracted flame orifice thereof in such manner as to drip into the cup-shaped device d3, when by igniting'the same the generating chamber c3, is heated up so as to hasten the vaporizing of `the Huid contained therein, and in order kthat by 4applying a ame thereto, the gas issuing from the exposed end of the contracted orifice c6, of the generating chambercg, may be readily ignited. The pressure of the gas from the chamber c3, through its contracted nozzle cl", is under control, so that the flame presented to the detiector plate and mixing With the surrounding air may according to requirements be of greater or less intensity but of high illuminating power, by reason of the perfect vaporization obtained due to the particular arrangement above explained of the several parts of the burner C. The extent, however, of the flame can be `regulatedy entirely by the operation of the needle cock d, by means of its key d', as clearly shown in Figs. l and 3.

With reference to Fig. modified form of the burner such as is especially adapted for inside lighting purposes. In this instance the longitudinal conduit or r3, is shown a slightly f channel' ci, of theA casting C, is closed by means'of a screw threaded plug f, and the ad-A mission of the fluidto the internaly gas genrection, through the nipple ,detachably connected with the T-coupling, vertical andjlongitudinal conduits'or channels cgand c', to the generating chamber c3. Surrounding the nipple ,'is asleeve i', for supporting to position a bracketj, provided with projecting armsj',

adapted to receiveand holdto position a j y In the supplyr pipe a, is mounted suitable wicking or analo-V l;

globe `or shade, not shown.

gous material a2, for permitting to a greater kor less extentof the regulation of the Iiowjot the fluid therefrom to the T-coupling g, con-v` 'trolled 'as to the escape of Vfluidftherefromrto, H

the burner proper by means of the cockgf, by the turning of the `key g'2 thereof. The

fluid in this device for'effect-ing vaporization in the first instance, is permitted by allowing f. a certain quantityof the same toy flow therel ltliroughinto the generatingchamber andto n i j escape therefromthrongh the contracted noz-` zle c6, by releasing the 'needlecock whence lit drips therefrom into the cup-shaped device di', and by the ,application ot' a flame thereto it is ignited in such manner as that by radiationthe chamber c3, is heated, in or` der to vaporize the fluid and continues under v due regulation of the tioW of uid through the parts of the burner to maintain the required ame at the exposed end of thecontracted orifice c6, of the 'generating chamber c3.

Oner of the main advantageous features of,

this device isL they presenting of the Huid to the burner forvaporizng the same at the hottest portion thereof, in rorder toproduce' a flame at the exposed end of the contracted nozzle of the generating chamber, whereby the uid is expeditiously vaporized` anda flame of great intensity and high'illuminatingpower is obtained. Hitherto in the use of vapor-burners, the fluid has generally been k 'f adjacent to the igniting point thereof, so that thesame may not only be thoroughly vaporf ized, butthe greatest number of unitsA of efliciency obtained there from forlightingpuri poses. Moreover, the mixing of the air at the point of r`ignition of the issuing vapor from the generating chamber greatly enhances the such a burner.

t The burner of my invention possesses illuminating quality of the gasy produced in f 4 by f kreason of itsconstructlon and arrangement the desirable features requisite for the expeditious vaporization of the Iiuid, the reduction of waste to aminimum and the obtaining of the greatest illuminating eect without requiringan abnormal amount of heat in and about the generating chamber for the obtaining of the results mentioned. The deflector plate as clearly illustrated in Fig. 2, is provided with an oblong slot f3, having a tightening screw f4, extending therethrough. This 'arrangement aords the means whereby the same may be set at an angle to the contracted iame orifice or Vapor discharge pipe c6, in order to increase or lessen the area of the llame, which is desirable in some instances should be under perfect regulation from an illuminating standpoint and more especially in house lighting Where a globe or shade is employed in connection with a burner of the type, for example, illustrated in Fig. 3.
