HYDRocARBoN INvERrED-MANTLE LAMP.

Specification of Letters Patent.

Patented Feb. `9, 1909.

Application led July 21, 1908. Serial No. 444,689.

To all whom it may concern:

' Be it known that L OseAR J. ySEEHAUSENl a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Hydrocarbon Inverted-Mantle Lamps, of which the following is a specification,

- This invention relates to a hydro carbon lamp of that type in which the mantle or mantles are inverted and which generates its' own vapor by the heat of the llame.

The invention has for one of its objects to improve and simplify the construction vand operation of lamps of this character so as to overcome objectionable features of lamps as heretofore constructed, and so as 4to be thoroughly reliable and efficient in use, and comparatively simple and inexpensive to manufacture.

Another object of the invention is the provision of a lamp in which the va orizer is a le quick starting and efficient operation of the burner, and whereby the condensed vapor will drain away from the tip or nozzle at the end of the valporizer when the lamp i-s shut down .and co ect at a suitable point where vaporization can be quickly and easily effected during the initial heating` of the vaporizer for starting of the lamp.

Another object of the invention is the novel and compact arrangement, Within the canopy 0r casing, of the vaporizer, mixing tube into which the vaporizer discharges, and gas-conducting material that supports the mantle of the burner of the lamp, the parts being so designed as to permit the easy and quick assembling thereof and at the same time producing a lamp of neat and attractive ap earance.

Tith these objects in .view and others, as

invention comprises the various novelfca tures of construction alnd arrangement of" parts which will be more fully described ereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawing which illustrates one embodiment of the invention, Figure l is a centrallvertical section of the lamp. Fig. 2 lis a similar section taken at right angles to the section of Fig. 1.

Similar reference `characters are employed to designate corresponding parts throughout the several views.

'ing cap 9 and around Referring to the drawing, A designates the canopy or casing of the burner which is preferably made in an upper and lower section l and 2 connected together by a telescoping joint at 3, and on the upper section is a hood or cover 4, which is of sheet metal spun or pressed into any desired shape, provlded with screws 5 at its bottom for supporting the globe that incloses the inverted mantle or mantles. l

- Arranged within the casing A is a gas-conducting tube Bin the general form of a uestion mark having a vertical portion 6 w ich is formed into a semicircular bend 7 at 'its u per .end for connection with the mixing c amber C, while the lower end is bent into a compound curve to terminate at 8 in a position coincident with the axis of the canopy ina single mantle burner. On the lower end of the gas-conducting tube is a gauze-carrythe mantle of the lamp. The mixing chamber C is a metal casting or the like of appropriate form which has an internally-threaded olpening 10 at its top into which is threaded t e receiving end of the tube B,'and the bottom of the chamber has a threaded opening 11 into which is screwed a nozzle or jetdischarging device 12. The casing has side openings 13 that are internally threaded for receiving the air inlet tubes 14 which have their outlet ends disposed in openings 15 in the lower section of the'canopyor CaSngA, the inner ends of the tube being screwed into' the side openings of the mixing chamber. The outer ends of the covered with gauze 16 secured in place-by crimping theedgcs of the tube as shown in Fig. 2 around the pcripheries of thcI gauze pieces, the gauze serving to prevent cross drafts through the fere with the effectiveoperation. The air inlet tubes constitute means for supporting the casing of the liquid chamber.

The vaporizer D wl'iich is arranged within the canopy, consists of a suitable length of L' tubing bent mto scmi-circu larsubstanti ally U shaped form with one end screwed into the ndzzle 12and is connected'thercby with` the bottom ofthe mixing tube, while the upper end of the other arm is connected with a needle valve easing 17. low stem that passes out of the canop through an opening 18a and in which 1s threaded a needle valve 19 'copera ting with the seat 20 to control or cut off the supply of this cap is suspended4 lamp which might `interi This casing 17 has a hol-- air inlet tubes 14 are liquid fuel, the valve being manipulated by a lia-nd Wheel 21 disposed outside the canopy A. The vaporizer is located ,in close proxirnity to the mantle and .is in the direct pathquickly heat and insure rapid generation oivapor and at the same time preventk the draining of liquid fuel into the mixing; chant ber and gas-conducting tube. Leading into the upper end of the canopy .is a uel-oon ducting pipe E which extends centi 'ily through the cover 4 and is bent laterally at 23 toward one side of the casi g, and then vertically at 24 so as to screw into the upper end oi the needlevalve casing l?, this pipe being filled with asbestos 25 or the like for preventing pulsation of the lamp. The upper end of the pi e E is connected with a suitable source oi liquid fuel supply under pressure and the liquid fuel feeds through the ipe, valve-casing 17, and into the vaporizer ln) Where it is. converted into vapor, and finally issues through the nozzle or tip E2 into the mixing tube. The jet of vapor in; duces a supply of air into the chamber through the tube i4, and the` mixture thus resulting is conveyed to the mantle through the ges-conducting pipe A.

From the foregoing description, taken in connection with the accompanying drawing, the advantages .of the construction and of the method of o eration Will be readily er arentto those s `lled in the art to which the invention appertains, and While I'liave vde scribedvthe principle ofo eration of the invention, together with t e devicewhieh noW consider to be the bestfembodiment thereof, I" desir'e to have it understood'tha-t 4the device shovvn is merely illustrative, end that such changes may be made when desired as are Within the scope of the claims appended hereto.

Having thus described the invention, Whe-t I claim is l. A hydro-carbon lamp of the inverted mantle type comprising` a gas-conducting tubedisposed vertically and having its upper end bent back upon itself, a mixing tube havingr top and bottom and side openings, said top opening receiving the upper end of the gas-conducting tube, e substantially U- shaped vaporizer having one arm connected with the bottom of the mixing chamber and the other erre latter, a li. te bottoni of -the with the vapori er, nected v/itn; the v discherfging liqu. ingits lower oasing, e trolling the il. from the last-noel oasiA g on j tube connchenil :L tween the ing; under the che; l f oi the casing, oJ lower end of 'the r bottom opening o secured to 'the noz doubled bach on trolled liquid ine conduit Werdly through j ri/'ith the seid 3.
