ACETYLENE-GAS GENERATOR.

To all whom it may concern:

Be itknown that we, RUFUS B. ALISON and WILLIAM G. ELLro'rr, citizens of the United States, residing at Vallejo, in the State of California, have invented certain new and useful Improvements in Acetylene-Gas Generators, of

which the following is a specification, reference being hadto the accompanying drawin s. I

' This invention relates to improvements in acetylene gas generators and consists of the novel construction, combination and ar-' 1angement of parts hereinafter fully devide a-simpleand practical generator of this character which will be reliable and safe in operation and from which it will be im- -possible for any gas to leak.

,The' above and other objects of the invention are attained in its preferred embodi-.

ment illustrated in the accompanying drawings, in which Figure 1 is a vertical sectional view through the improved gas generator; Fig. 2 is a side ,elevation showing the safety outlet pipe in section; Fig. 3 is a detail perspective of the valve; and Fig. 4 is a perspective View of the adjustable tube which closes the safety outlet pipe.

.The invention com rises a water tank 1 preferably of cylin rical form and surrounding, this tank is a cylinder 2,"the .bot-

tom portion of which has an angular flan e' 3 WhlCh is attached to the outer face of t e tank 1 adjacent its bottom so as to form an annular water sealin chamber lbetween the parts 1, '2, said cham er4 being in communication with the interior of the tank 1 through openings 5, as clearly shown in Fig. l. 7 r The liquid in the annular s ace or chamber 4 forms a seal for a gas bel 6, which latter is in the form of an inverted cylinder and hassecured in its flap top a cylindrical carbid receptacle or hopper 7. The bell is guided in its sliding movement by means of brackets 8 which receive and slide upon-upright guide rods 9 secured at their lower ends to the wallor cylinder 2 at diametter has suspende from it by means of a chain or thelike 11a hook 12' adapted .to

be engagedwith an eye 13 on the carbid rets other end provided which is suflicient to hold the valve 15 closed against the contents of the receptacle or ceptacle- 6 when the bell is elevated for the purpose of holding the same in such elevated position while the receptacle 7 is being filled. The carbid receptacle or hopper 7 is centrally arranged in the top of the bell and has a cone-shaped bottom 14 formed-with an opening which provides a seat fora coneshaped .valve 15. The latter, is arranged on the intermediate portion of a stem 16, the upper end of which is pointed and projects into .the carbid in the hopper or holder 7 so as toloosen the same when the valve is moved. 7 V 7 The lower end of the valve stem 16 is pivoted to a-lever 18 fulcrumed intermediate its ends on a bracket 19 depending from the bottom of the carbid receptacle and having with a weight 20 holder 7. The latter is filled with carbid through a centrally arranged opening 21 in its top, said .opening 21 being closed by the removable screw plug22 having a grooved flange in which latter is a packing ring or gasket 23, as clearly shown in Fig. 1. This construction, it will be noted, effectively prevents gas irorn leaking fiom the carbid holder or receptacle. v

24 denotes a; service pipe arranged .vertically'in the tank v1 and supported rigidly in by means of up er and lower brackets 25. The lower end 0 the-pipe 24 extends through the wall of the tank, contains a controlling valve 26 and is in communication with the lower end of a suitable gas filter or purifier 2-7 from the upper end of which latter jects a pipe 28 which supplies the gas to the,

por-

burners- The upper end of the service or supply pipe 24 isbent angularly, as shown at 29, andso disposed-that it forms a trip or stop for the weighted end 20 of the valve lever 20, whereby when the gas bell lowersto a predetermined ,point the enga ement of the "weight 20 with said part 29 .o

in"Ij.ig.'1,so that the carbid in the holder or rece tank 30 denotes a safet outlet vertically in the tan 1 and aving its upper end disposed. above the water level therein'and its lower end extending through v the wall-of said'taiik and from thence to the. atmosphere, a drip cook 31 being arranged n pipe 30. Ar-

the lowermost .part of'said *Iatent/ed Mar. 8,'1910,

;the pipe willcause the valve to be lowered, as shown ptacle 7 will. .drop'into the water in the Lipe arranged v telescope theu'pper open endof the portion of the pip a tube 32 having adgacent to its bottom an opening 33 and its upper ably connected to an operating and adjusting rod 34. The rod 34; slides through a stuliing'b'ox 35 in the top of the bell 6 and has at its ripper or outer end a fingerpiece 36 by means of which latter said-rod may be raised or lowered in the stuffing box to adjust the position of the telescoping tube 32. By reason of the adjustment of the latter it will be seen that the instant the bell rises to a predetermined position the gas within it will escape to the atmosphere, thereby preventing alldanger of explosions due to over generation of gas. 1

37 denotes an agitator arranged in the bottom'of the tank 1 and in the formof a shaft having a plurality of crank portions. One end of the shaft 87 extends through a stufiing box 38 and is provided with a crank handle 39.

4.0 denotes a cleaning out valve or cock through which latter the water and settlings in the tank may be removed when the agitator 37 is rotated.

41 denotes a filling spout arranged on one side of the wall or cylinder 2- adjacentits top.

In operation, it will be seen that as the gas is consumed, the bell 6 lowers until the weight 20 is lifted by its contact with the end 29 of the service pipe, whereupon the valve 15 will be lowered to open position, as shown in Fig. 1. When this happens, the carbid falls from the holder 6 into the water of the tank and the gas generated from the carbid collects in the bell and causes the same-to rise, thereby lifting the weigh-t 20 off of the end 29 of the service pipe so that said weight will close the valve 15. \Vhen it is desired to refill the carbid holder or receptacle the bell 'is secured inan elevated osition by engaging the hook l2 in'the eye 13, thereby allowing the weight 20 to close valve 15 so that little, if any, gas will be allowed to escape into the room or building through the filling opening 21 of the carbid holder. Should more gasbe generated than is consumed the surplus gas Wlll escape to i through the pipe 30 the inl the atmosphere stunt the opening 33 in the telescoping tube passes above the water level in the tank. From the foregoing it will be seen that the construction of the improved generator end closed and suitis such that it "will occup but little floor space and will be exceedingly strong and l durable.

The safety escape for an excessive amount I of gas contains no springs or other parts liable to get out of order so that it is exceedingly reliable in operation.

All parts of the generator are 'so con- 7 structed that it will be impossible for gas to leak and hence the liability of explosions is reduced to a minimum.

is claimed is:

ator comprising a cylindrical water tank formed with an open top and havingadjacent its bottom an annular "series otopenings, a' cylinder surrounding the upper portion of the tank and formed at its bottom with an inwardly extending flange united to the wall of the tank at a point beneath rising from sa1d cylslidably engaged-with said frame, a carbid holder centrally arranged in the top of'the bell and having an outlet in its bottom, a weight controlled valve to control said outlet opening, brackets projecting inwardly from the wall of the water tank, an upright gas outlet pipe arranged in the last mentioned brackets and having its upper end turned outwardly and adapted to be engaged by the weight of said valve, an eye upon thecarbid holder, and a flexibly suspended hook' upon the top of said supporting and guiding frame and adapted to i engage said eye for the purpose set forth.

in testimony whereof we hereuntonflix our signatures in the presence of two witnesses.
