The water may be poured into the tunnel 9 in order to replenish the tank with water. for slaking the carbid. A portion of the wall). adjacent to the bottom l has a vertical slot 16 therein Awhich is cov-' ered by a box 17 secured to the exterior ot thewall, the box having a neck portion 18 thereon extending upward a suitable distance and secured to theexterior of the casing 3, the upper end ot' the neck preferably having a funnel 19 thereon. 'A guide 2O is secured Ato the casing 3 ywithin the funnel and a guide 2l is secured tothe inner side ofy the wall 2. A rod 22 extends throughthe guide 2O and has a handle 23 on its upper end which when desired may rbe supported onfan arm24 that is pivotally supported in a bracket 25, Secured tothe casing 3, and

- the rod may be lowered when the arm is swung away from beneath the handle. The normally lower end of the rod 22, has a lateral arm 2G thereon within the box 17 Vand a return rod 27 extends from the arm upward through the guide 2l and has a cross-` bar 28 thereon which is provided with aA downwardly extending linger 29 whichis in contact with the inner side ot the wallv 2 behind a. vertical guide 30 on the wall. c The slaking water may if desired be poured also' into. the unnell9, or the tunnel may receive water for` washing out the residuum from tank. n The yupper portion of the casing 3 has an .5; aperture'3l therein provided with a funnel 35 32, in order that theA sealing water or liquid may be conveniently poured into the sealing compartment.v Anoutlet pipe 33 is arranged adjacent tothe inner side ot the wall 2 and is supported on an elbow 34 which is connected to a ldischarge pipe 35 extending through and secured to the wall, the upper endr of the pipe 33 .preferablyfhaving an* elbow 3G thereon to prevent moisture lfrom gas.

' The generator is provided with a safetyvalve which comprises an upright rpipe 37 supported by an elbow 38 adjacent to the inner side of the wall 2, the elbow being yconnected yto and supported by an escape pipe 39 which extends through and is secured to the wall 2. The-upper open end of the pipe '37 is normally .closed agalnst the escape ofgas by means of a cap comprising y a tube 40 extending down over the pipe a 5 5` suitable distance, the tube havingfa head 41 closingits upper end, the lower end of the tube having a cylindrical shaped screen il secured thereto and extending about the pipe 37, the cap being elevated by means of a chain 43 connected thereto when4 the gas` is generated in excess of requirements.

A gas-bell comprises a cylindrical shell t4 of suitable diameter tofreely pass over the wall Aofl the tank and within.' the casing3, the lower end of the bell being open and imrtively andthe ends of'the vdownwardly extending ears 66 and G7 respecti-vely, providedrespectively with pivots "63. The plates 59 and 60 are maintained in parallelfrelation by means of thimbles 69 y and tie-rods 70. `are support-ed in the two plates 59 and 60 :tween the plates 6l andr 62. bodies 73 and 74 are mounted respectively mersed in water, as is customary in gas generators, the shell having a, conical top/l5 into the middle Portion of which extends a cylindrical magazine for holding the carbid, the magazine having a hopper shaped bottom 47 and a top 4S, the top being provided with `a removable filling plug 49.

box which has two upright side plates 59 and G0, ot' suitable length, which are connected at their upper ends tor the lower open end of the hopper `bottom 47, yand tworelatively short plates Gl and 62 connected also tothe ('bottomd and to the plates 59 Aand 60. TheV yplates form a rectangular discharge "chute (33 through which the carbid falls into the 57 and 5S are mounted tank. The plates 59 and V60 have extensions t Gel and 65,011 their lower portions respec extensions have Two pivot rods 7l and`72 and extend from one to the rother of the plates at a suitablefdistance below the'plane of the lower end of the plates 6l and 62 and somewhat farther apart than the space be- Two valve on the pivots `7l and 72 between the side plates 59 and 60 and extend upward to the' lower ends of the plates 61 and 62., the valves having curved upper working faces 75 and Q76 respectively, which are adapted to close the chute or partially `open it. The valve bodiesv are provided at the upper portions thereof with pvot rods 77 and. 78 respectively, twostiff links 7 9. and SObeing connected to the rod 77, vtwo similar links 81 and 82 being connected to the rod 7S. The two plates 59 and 60 have vertical guide slots 83 and 8i therein,respectively, n tween thepivots 7l and 72. A pivot rod 85 extends through `and is guided in the two guide slots and is connected with all the links, and two operating rods 86 and 87 are f connected at one end to the pvotrod 85.

An operating lever comprises two arms SS and 89 connected at oneend to thepivot 68, and a cross bar 90 connected to the opposite end' of the. arms. A pivot rod k91 is connected to the arms 'ofthe lever yand also to the normally lower ends ot' the rods S6 and midway beisc l fil-Lithinible y92;.is' preferablyplaced ybe-j filled and refilled with carbid, while the l suitable distance tiveenithetwo arms of the leverfandfsecured thereto by a tiero'd 93 so'that theflever' may `v `be, stopped in itsy yupward movement byij` the fthiin'blecoming in. contact y with the lower edges'of the side plates and @0in which position the valve ,-,is'wide-open.

In order to prevent the carbidy from pack-1 f ing on the bottom of the magazine a suitable number of standards 95 are secured upon the bottom I7 and support a cone 96 at a 'above Lthe bottom.

In some cases n weight 97 on its lower l,end `composed of lead in order to maintain the 'desired degree of pressure on the gas. y f

In practical use `the generating tank contains a suitable ,quantityfof water as does also the sealing compartment, and normally the cross bar 28 is depressed. The plug 49 is removed 'while thev magazine is being feed val-ve is closed. If it is desired to feed a quantity of carbid by hand or quickly generate the gas, the attendant raises the handle 23 and again pushes it down vor may hold it up byvmevans of the arm 24. Vhen y rating lever,

, again comes in contact witli'tlie cross bar 28y magazine.
