To all 'whom it may concern.'

Beit known that I, OscAn A. ARNEsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinols, have invented certain new and useful Improvements in Gasolene or Vapor Lamps, of which the followinfJr is a specification.

This invention relates to improvements in the construction and arrangement of parts in lam commonly` known as gasolene or vapor amps and is more particularly adapted to that type of lamps in which inverted mantles are used for generatin the light, al-v thou h certain features are a so applicable to -ot er types of such lam s. Its objects are to provi( e a new form oflamp which will be more efficient and satisfactory in operation than those heretofore used, which will be neat and attractive in appearance, and which will roduce an even and steady light of Great br iancy.

attain these advanta es in my improved lamp, a preferred form o which is shown in the accompanying drawings, in which- Figure 1 is a vertical section, arts being broken away orshown in full or convenience in illustration; Fig. 2 is a detail showing the arrangement of the double burners; vandFig. 3 is a sectional detail showing the burner construction.

As shown in these drawings, lidesignates any suitable form of hanger which is 'provi( ed with one or more pipe connections 5 5 for connection with the main supply ipes. A valve 6 is connected with the anger 4 and with a depending pipe 7 which carnes at its opposite end a tee 8, this tee having only one passage way through the same to allow the suppl to pass through the coiled pipe 9 which lea(v s down to a valve 10, makin connection with a horizontal pipe 11 at the ottom of the lamp. This horizontal pipe or tting 11 leads to a generator tube 12 running dlametrically across the bottom of the lamp and connected at its o posite end with an upwardly extending er Aorated nipple 13 leading into an a1r cham er 14 and.

directed toward the open mouth of a vertical ipe 15 leading upward from said air chamer. The air chamber is entirel closed except for'a short inlet pipe 16 eading out through the side of the lamp. The mixing pipe 15 is connected at the top with a horizontal'iitting 16 having a passage way therethrough leading to a vertical pi 17 at about the center of the lamp, whic carries the mixed air and gas down to a forked fitting 18 which in turn connects with two downwardly' projecting tubes 19 and20 havin burners 21-21 at the lower ends thereo The burners 21 are threaded to screw on the ends ofthe pipes 19 and 20 and are provided with flaring outlets 22 to direct the gas out toward the surface of the mantles 23. The mouth of the burner 22 is provided with a screen 24 which is held in position by spinnin the end ofthe burner 21 in to engage wit the lower outer edge of said screen. The outer surface of the lower end of the burner is provided. with a groove 25, so that a string 26 m-ay be passed around the upper end of the mantle 23 and tied around said mantle to hold the same in position-on the burner. The frame construction of the lamp is completed by a pipe or rod 27 connecting between the lower end of the tee 8 and an upwardly projecting stem on the iitting 16, thereby serving to hold said litting and its connected parts. A rod 28 also connects with a lateral projection on said fitting 16 and with the pipe or {itting 11 heretofore described.

Around the centrali disposed portions of the lam frame is a shell or casing 29 connected y means of strips 30 and a shield plate 31 with a cover portion 32 which is ccnnected by means of a thimble or sleeve 33 and a set-screw 34, with the pipe 27, and servesto hold the casin in adjusted position. The casing 29 is slotted at the bottom at 35 to receive the pi e 11 and is provided with a downwardly an outwardly projecting shade support 36 which is held in position by means of screws 37 passing through said casin 29. This support 36 serves to hold the sha e or globe 38 which may be made in any desired style. The casing 29 is provided Wlth a hole to receive the air inlet 16, heretofore described, and with a series of holes 39 near the top to allow for the exit of the heated gases or for the inlet of air to cool the u per portion of the burner pipes, there being a so an outlet for the gas formed between the upper end of the casing 29 and the cover 32. A deflector 40 is inserted below the cover 32 in order to direct the gases out through the opening underneath said cover.

T arrangement of the air mlet 1s of partlcular importance, a's the air is only allowed to ass' in through a large opening at one side o the mixin chamber, which tends to prevent iiickermg of the lamp and reduce the noise of the inrushing air to a minimum. It will be supply is noted that the arrangement whereby the prevented from bein heated and \what 1s commonly termed doub e generation is prevented, is an important feature in connection with this improved lamp, as it in- `27, so that a eures a steady light without flickering.

The arrangement ofthe casing is such that by removing the air inlet tube and the shade holder, it ma be easily shoved up on the rod of the operating parts of the burner are readily exposed for cleaning or ins ection.
