Be it 'known that I, HENRY OMEARA, a

citizen of the United States,

t I residing at Sioux Falls, in the county of Minnehaha and State of South Dakota, have invented certain new and useful Improvements in Acetylene-Gas Generators, andI do declare thefollowing to be'a full, clear, and exactdescriptioii of the invention, such' as will enable others skilled in the art to which ap'pertains to make and u'se the same.

This invention relates to improvements in acetylene gas'generators and the primaryobject of the inventionis to'provide a simply constructed generator of, theherein debed character,'w hich will be eflicient and reliable in operation.

A 'secondary object is td' provide simple H and eificientmeanspoperated by the descent of the gasbell; for openingthe valve in th e carbid hopper, thereby allowing 'a new charge of carbid; to enter thegenerating chamber.

v i Still another: obj is tofprovide structure wherebythe tube which conducts the carbid from the hopper'f't'o the generating 1 hopper being closed. Figitis adetailhorizontal section on the line 4,430f Fig. 5;

Inthe I accompanying drawings, "I have shown improved generator as comprising, inf general, a water-tank 1, a gas bell 2, a carbid- 'hopper "3 and various "connections for controlling the feedr'of the carbid and for alsoreceivingthe gas generated.

The water is preferably cylindrical andis open at its upper end, while its lower end isclosed by asolid bottom 4:. Spaced a suitable distancefromy said bottom &' is a horizontal partition 5' having its J central portion bulged upwardly as at 6 HENRY oMEARA Ol-l SIOUX FALLS, SOUTH DAKOTA.

and in communication with the interior of an upright pipe 7. This pipe 7 has atWofold function y of conveying carbid to the "spacebetween the bottom 4: and thepa rtition 5 and of conducting the gas generated in said space to the house connection or serv- 93 P P a As clearly shown in the drawings, the bell'2 is of cylindrical contour and is provided with a solid top 8, while its lower end is entirely open as is common with devices of this character. The top 8 ofthe bell is provided with a central opening 9 within which a sleeve 10 is rigidly secured, said sleeve surrounding the pipe 7 and having its lower end flared outwardly as at 11. Thus it will beseenthat thepipe acts also as in its ascent and a guide for thebe ll 2 descent. The top 8 of the bell 2 is also provided with an eccentric opening 12 from whicha small cylinder 13 rises, said cylin der'being closedat its upper end and provided with a suitable Ioopor eye 14:, the function of which will hereinafter appear.

In addition to the hereinbefore set forth uses of the pipe Tyit also forms a rigid supportfor the carbid hopper 3., Said hopper comprises a funnel shaped lowerjend 15 which is in communication withfthe interior of the pipe 7 and is provided with an upright, wall 16 at its upper edge. The

upper edge of the wall 16 is provided with a cover 17, the latter having a threaded filling opening 18 which'is normally'closed by a screw cap'19. Vithin the hopperB and disposed in vertical alinement with the pipe -7, is a substantially cylindrical guide 20 which,"as shown, is'c'losed at itsupper end while itslower end is entirely open and is spaced from the junction of the'lower end 15 of the hopper 3, with theZpipeTI. The

guide 20 may be rigidly secured in this ;po

sitlon' in any suitable manner, a sleeve 21,

leading from said guide 20 through thle wall 16, usually answering this purpose. The

outer end of the sleeve 21 is externally threaded and engaged with internal threads in a boss 22,formed on the outer side of the wall '16, said outer end of the tubebeing provided with anannular'collar 21 which contacts with the inner side of said wall. As clearly seen in Fig. 3, the boss 22 receives, in its outer end, a packing nut 22 between whichiand the'adjacentend of the tube, 21;a

packingring is located,the adjacent ends of said tube and said nut being countersunk to force said packing ring into engagement with a shaft 23 which is located in said tube and is provided on its-inner and outer ends with crank arms,2at and respectively, said arms pro ect1ng in opposite dlrectlons from said shaft. The crank arm 24 is loosely connected, through the instrumentality of a plurality of links 26, to the upper endof a weighted valve 27, said valve being coneshaped at its lower end as shown at 28, said As seen in Fig. 3, the guide 20 is formed with a laterally extending boss 20 through which the inner end of the tube 21 prOJects into the interior of said guide, a nut 20 being threaded on said inner end thus clamping the boss 20 securely between said nut and a second annular collar 21 which is formed on the inner end portion of the sleeve 21. By this arrangement of parts, it will be seen that the guide 20 is rigidly supported within the hopper and that the outer end of the tube 2l acts asvone member ofa stuffing box.

hen the valve 27 is seated, the crank arm 25 will extend upwardly at substantially an angle of 45 and the gas hell 2 will be supported by the pressure of the generated gas as will be hereinafter described. As the gas is exhausted from the interior of the bell, and said bell gradually descends, it becomes expedient to provide means for automatically raising the valve 27, thereby allowing the, fresh 7, charge of carbid to descend through thepipe 7 and into the generating chamber between thebottom 4: of the tank I, and the partition 5 therein. For this purpose I employa chain 29 or other suitable connection, between the outer end of the arm 25, and the loop or eye 14. Thus it will readily be seen, that when the bell 2 de scends, said chain will pull downwardly upon the arm' 25, this movement rocking the shaft 23 and through the action of the crank arm2l and the links 26, raising the valve 27 to allowa charge of carbid to drop into thejpipe By reference to Fig. 1, it Will beseenthat the only outlet from the generatingfchamber, is the pipe 7 andtherefore allgas' generated in said chamber must neccssarily rise within said pipe. For the purpose of conducting the generated gas from the interior of the pipe 7, to the house connection and to the interior of the bell 2,.I provide a horizontal pipe 30 which extends outwardly fromthe pipe 7 and passes through the upright wall of the tank 1, its outer end being'in communication with a filter 31, the latter having a suitable nipple 32 to which the service pipe is connected. Intermediate its ends, the pipe 30 is'provided with an outwardly opening check valve 33 and with a valve 34: which -.may be employed for. cutting off the flow of gas entirely, or for conducting it to any one of the number of discharge pipes (not shown). The pipe 30 is provided, between the check valve 33 and its outer end, with a depending pipe 35 which hasits lower end turned inwardly as at 36, beneath the lower end of the hell 2 and rises as at 37,, its u pperiend discharging into the cylinder :13 carried by the topof the'bell 2, i v v 'With the parts asabove described, the op;

bid hopper 3 is filled with carbid and the shaft 23 is rocked in such a manner as to cause the valve 27 to rise within the guide from said-burners. The major pa ft of the gas generated will,' however, descend through the pipe 35 and willhtherefore be discharged in the upper end of the gas bell 2, said bell being substantially filled with waterl from the tank l. The gas within the hell; 2 will now caus'e'said bell to rise and will-thus re lease all" tensionon the chain} 2 9. The weighted valve 27 will now drop'by gravity to automatically check the ,des'centof the carbid and consequently no more generation said bell has been exhausted and again descends/ a i .H

By the provision of the outwardly opening check valve 33, itwill be seen that'the gas to the generating chamber through the pipes 35,30and7. i

For the purpose ofremovingthe exhausted carbid or sludge, from 'the generating chamber, I provide a valvedpipe 4:0 which communicates witha suitable suction pinnp and with the interior of said. generating chamber. The suction through thepipeAO, although removing the major part of said sludge, would not be sufficiently strong to reach all parts of said chamber. Irther efore 20 and thereby allow a quantityofsaid.cara

throughsaid service pipe and be discharged 7 from the hell 2 is prevented from'returning eration of the device is as follows: The carioo will take place until-some of the gaswithin iio provide an agitating finger or rod 41 which lies iiponthe bottom 4 and is provided with an upright operating rod 42 which ,passes revolubly through a tube i3, within the tank 7 1 and hasits upper endtnrned laterally; as

,1 44: toprovide a suitable operating handle.

By the provision of this agitating means, the sludgeupon said bottom: 4, maybe read- -'ily loosened andtherefore thesuction within the pipe 40 will be sufficient to remove the 3 same.

From the foregoing description, taken in f connection with the accompanying draw- ,lngs, the construction and operatlonof the invention will be readily understood without requiring a more extended explanation. Various changes in form, proportion and 'minor details may be resorted to without do a parting from the spirit of the invention'as claimed, 1 r
