Application tiled July 7, 1909. lertal No. 506.295.

To all whom it may concern:

lie it known that l, WILLIAM C. Comuna, a citizen ot' the United States, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Lamps, of which the following is a specitication.

'lhe present invention relates more particularly to portable readin lamps that burn vaporized alcohol, gaso ene or otheihydriaarbons.

(lne of the primary objects of the present. invention is to provide a practical structure of a novel character, which is exceedingly compact, so that. the parts occupy but little space, and the clumsy appearance which is a feature of this type of structure is obviated.

A further object is to provide a structure in which the amount of light can be varied, as desired, the valve being such that. danger of clogging and inoperativeness is completclly overcome.

A urther object ,is to provide a structure, in which the vital parts of the lump are readily accessible, for the purpose of cleaning and re air.

hs pre erred embodiment. of the invention is illustrated in the accompanying drawings, wliercinz Fi ure l is a side elevation of the lump the s iads'iuid its nupport. being illustrated in section. Fig. 2 is a vertical aectional view through the upper portion of the lainlp, the Haine being shown on an enlarged sca e. Fig. 3 is a detail sectional view partially in section of the mixing chamber and one of the mantle supports. Fi f. 4 is a horizontal Section on the line"\t-4 o Fig. 2. Fig. 5 is a rear elevation of the structure disciosed in lei 'a 4s i .'iuiilar reference numerals designate eorresponding parts in all thi.I figures ot' the drawings.

ln. the eiulauliment illustrated. a basa ti is employed thatis in the forni of a reservoir or font, being provided with n suitable lilling nipple 'i' having a maplin f H, to which an oidnary air pump naiv le connected. tubular standard ll rises troni the font or verm-voir. and constitutes means for enndueting the fuel from said reservoir to the illuminating means. as will be obvious.

' This standard carries at its upper end a vertical vapori/.ing

tube l0 having un otl'sct l upper end ll, which is provided with a de i pending vapor discharge nipple l2, located along one side of the tube l0 in spaced :ula-t tion thereto. The otl'srt portion ll is extended, as `hewn at 13 beyond the nipple tit and foi-ins a bearing for a' rotary cut-o valve t4 havingv an exposed handle l5, and being provided at ita inner end with a controlling port iti that is movable into and out of register with 4the nipple l2.

A vertical mixing.r chamber is located alongside the va )orizing tube 10, and cunprises a inain bt y 17 and a vertical Banaan tube 18 that extends downwardly into the body 17, and terminates contiguous to the 'lower end thereof. Bunsen tube is disposed in line with the nipple l2, and it is farthennore p with a right'angnlarly disposed pipe laotion 1t), forming an nir inlet the outer 0l' open end of which is controlled by an adjustable cap 20, mid cap constituti meat for varyin' the supply of air, as w' ba apparent. 'l e body 1 is fu vided with diver by the upper portion o said body, and havi depending ripples 23, the lower ends of w ich are cnvei by perforated caps 24. Thess nipples constitute supports for inverted inantlcs 25 of the usual type. The mixing chamber is vertically adjust able on the tubs l0, and therefore tbs upper end of the llanxen tubo t8 has un ol'set collar 26 alidabls upon the tubo, and normally held in position theieon b a set. screw 27.

With t iis construction, it will be obvious that. the inantles are disposed ou opposite sides of the vaporizing tube, and cunasquently if the mantles are made incanddcent, the fuel tlowing upward the nt arms 22 carried pelled downward tliro'tllfh the llunsen tube 18. io tlow 0 the will eause an inriiuli of the itil' tlimtth pi e ttt. aud this air mixin with the vaql', wil creato a 'ascolta fue in the nnxin chamber l?. lliho fuel will be oonductc through the arias 2l to the mantieni.

It will be obvious by reference to Fig. 9 that lthe tructaro is'exceediiglly compact, and yet the necessiti' length o Imaan t8 is secured. lturt iermore it will be mitad that iinthis structure the working ps rta of the lain'p inost liable to elo r, arsleadily accessible, inasmuch as by waiting tha itat The upper end of tllia.

tube l0 will be vaporized and will sxy the nip ls 19 into l than ' tht' t'ttptttizing tttlw.
