To all whom 'it may concern:

Be it known that I, RICIARD H. VVELLES,`

a citizen o f the United States, residing at Kenosha, 1n the county of Kenosha and 5 State of Wisconsin, have invented certain new and useful Im rovements in Acetylene- Generators, of w 'ch the following is a specification.

My invention relates to acetyleneenerators, and'more particularly to that c ass of portable generators designed lto roduce as or use in furnishing headlights fdr vehic es, such as automobiles.

The object of my invention is to provide a simple,.`.z compact, safe, and easily-manipulated 'generator whichwill occupy but` little space and be capable withja ,single charge of yleldin f gas forlivhting purposes for a considerabglc period o time.'I l

sists in certain features of novelty and utility in a device of this character substantially as hereinafter described and claimed.

Referring to the accompanyi drawings, wherein is shown a generator em odying the novel vfeatures of'my invention inl a preferred form, Figure 1 is a vertical longitudinal sectional view of the 'apparatus diagonally through the externalcaslng of the gen- 30 'erator on the line :eMac of- Fig. 2j, Fig. 2 is a top plan view; Fig. is a detail view illustrating the means for introducing'water-tol the carbid-chamber. and meansl for controlling said introduction of water and the disthe admission of water has been cut oli", and

Fig. 4 is a detailfragmentary view of a portion of the base of the'generation-chamber', illustrating the means for uniting the latter to the t base of the' external easing or water-chamber. Referring tothe ydrawings for a more de# tailed description of the device, `5, designates' Ythe external casing ofv the generator, which sucha form being reasons, which wi l herelnafter appear casing 5 constitutes a `water-cln'ur'iber de-4 signed when the appara'tuseis fullycliiilged vto i fibrous Wick 9, which serves to preventk To this and other en ds my invention con.

charge of the residue of gas' produced after.

is here shown as rectangular in 'cross-section,l

preferred for va varietyilf:

evaporation or spilling of the water in the casing and at the same time to admit the' fibrous wick '9" one endof-the latter is providedwith a bent Wire 10, attached thereto. Centrally within the llower portion of the casing 5 is disposed'a cy'lindflc'al casing'll, inclosing the generation-chamber of kthe apparatus, and within the casing'11 a' pyingthe major portion of the space thereof 1s dis osed the cylindrical carbid-receptacle 12, a apted to contain a charge of carbid", (indicated at 13). The central circular portion of the lower end of" the outer casing 5 is open and is surrounded by a de ending flange l14 Within which snu 1y fits t lower en of the casing 11 0F the encratlonchamber, and the lower margins'o the flange 14 andcasing 11 seat upon a packing-ring 15,

-itself contained within an annular groove or 11 by means of a pair of oppositelyocated vertlcaltie-rods 17, (see Flgs. 2 and' 4), the.

lower ends of which are secured in ears or lugs'- 18, .projecting laterally-and op ositely `from the cover 16, said rodsA exten :lng 11p--Y vwardly through vertical sleeves 5*"betw'een the lower and upper walls of the casing 5 and extending'tlirough the latter 4 and equipped on their upper endsfwith'thumb-nuts 19,by turningy up whichthe bottom cap, or cover 16 The cover 16 e open is drawn tightly aglainst thei'lower margins e' water and chambers n an obvious manner.

mounted a sleeve 20, the open upper end of which` extends throu h the top Wall of the water-chamber 5 an has a quadrant notch On :the upper end of the casing 11 of the" generation-chamber and centrallyoth'ereof is.

'generation p which constitute stops for the'stembfajvalveplu ,hereinafter fdescribed. Fittedltii turn' with across-piece 22 for readiiy turning the same by the thumb and En er and with a radially-projecting pin 21', resigned to ce gplerate with the notch 2O1 to eiiect the stop.

e lower endvof the rod 21 terminates in a conical valve-plug 23, which snugly fits a correspondingly-shaped bore in a valveblock 24, secured to the under side of the top Wall of the casing 11. rlhe'valve-plug 23 1s axially bored from its lower end, as shown at 25, up to a point where the bore intersects a At e radial passage 27 oi the valve-block.

The said tu lateral opening 26, Fig. 3, which latter is adapted to communicate with either of a pair of radial horizontal passages 27 and 28,

formed in the valve-block 24 right angles i to each other. l

- Extending entirely' across the water-Cirami ber and at its opposite ends mounted in inwardly-curved walls 5L at opposite corners et said chamber is a horizontal tube 29, closed at its outer ends by threaded caps 3() and containing a filling of spongy or absorbent material inthe nature of a wick 31. lt will be Yobserved that the tube 2Q lies in a direction parallel with the diagonal of the top and bottom walls of the outer casing/end passes through and across the upper end of the generation-chamber 11, said tube lying against one side ofthe valve-block 24 and having an o ening therein which communicates with e is urther provided on its under side at points between the outer wall of the casin l1 and the inner wall of the casply lling the water-chamber 5. The lower end of the valve-plug23 extends downwardly below the valve-block 24 to constitute a discharge-nozzle 23 for water passing there-V through, and the outer surface of said nozzle is externally threaded to receive a washer S3 and nut 34, by which a tight 'oint between the valvelugand the va vel locli may .be maintained).

Mounted in and between the upper and lower covers l2 and l2`bof the carbid-receptacle 12 and coaxially thereof is a perforated tube 35, the upper' open. end of which is in line with and directly beneath the dischargenozzle 23a of the valve-plug. y

Y Tapping the top wall of the generationu chamber 11 is a gasdischarge pipe SG, which extends upwardly through the upper portion of the water-chamber and through the top wall ot the latter and at itev upper end may connect with the servicciipc leading' The.

. extending blow-oil pipe 37, which coumiunicates at its inner end with the radial passage 28 ofthe block and through the latter with the axial bore of the valve-plug when the latter is turned to bring its aperture 26 into apertures 32, designed to admit Water to the 'interior of the tube from the su p- `,open upper end of .the sleeve and is equipped l register with the passage 28. The-outer end ofthe tube 37 extends through the side wa'lls fof the lgeneration-chamber and` of the waterchamber alongside of and parallel with the wicktube 29, communicating at its outer end freely with the atmosphere.

YTo charge the generator, the thumb-nutsi 1Q are removed and the bottoni cover 16 withdra-wn, the tie-rods 17 being at the same" Atime withdrawn through their containingsleeves v5". The carbid-receptacle is at the same time withdrawn from the generationehamber, and the top cover thereof being removed. the carbid is charged thereinto around the central erforated tube 35 and the cover replaced. he receptacle is then reinserted within the'generation-chamber and -r the cover 16 reapplied, the gasket 15 being drawn hard against r-,the lower ends of the water and generation chambers by the turning up of' the thumbnuts 19. The cap 7 having then been removed, the outer casing is' iilled with water preferably to its entire capacity, and the cover 7,l is then returned to closing position. Upon then turning the valve-plug until the cross-piece at the upper end thereof points to the word On on the top ofthe casing the aperture 26'of the valveplug will be brought into register with the passage 27 and the water which enters the tube 29 and seeps through the absorbent lilling thereof is free to trickle .and drop through the vertical axial bore of the valve-plug down within the perforated tube 35, through the l numerous apertures ot which it trickles, at#

taeking the surrounding carbid and thereby generating the gas, which rises through the' tube and through an annular opening 12c in ,the cover et' the carbid-receptacle surrounding the upper end of the tube and is inally discharged to the servicepipe through the discharge-pipe 36. vVhen it' isv desired to discontinue the generation of 'the gas, the stem oi the-valve-plug is given a: quarterturn to a position where the cross-head 22 points to the word Oft which movement throws the aperture 26 of the valve-plug out' of register with the inlet-passage 27, cutting oli' the latter, and into register with'the out` let-passage 2S, comm umcating with the blowofi pipe Il! whereby any residuum of gas that may remain in the generation-chamber after the admission of water has been cut of:1 is discharged to the atmosphere to relieve any abnormal pressure that ymight be created thereby. The generation of gas may be renewed at any time by a simple resetting of the valve-plug to a point to cut off the blowoffl pipe and connect with the water-inlet tu e.

heat that accompanies the liberation of the gas. By.'-in'dentiiig the diagonally oppo# formed against inury. resnltingfiom dental contact wit ,external.objectsgvvhicn in a portable generator isafeature'.offcoiif'` 'valveblock tothe ..eicclusion of tieother,
