HENRY E. PRILLWITZ, or CHICAGO, ILLINOIS.

. AcE'rYLENE-GAS GENERATOR.

To aZZfw/"wm'z't may concern.'

i e itknown that I, HENRY l". a citizen of the Unitedv States, residing at in the countyof Cook and State of Illinois, have invented new and usefullm.- provements in Acetylene-G'as Generators, of which the following is a specification.

rllhis invention relates to acetylene gas generators in which the carbidis fed into the water in small quantities or charges, and its obj ect is to provide a novel and impro ved carbid feed which is simple in construction.

' and economical, and positive and eiicient in operation. lt

feeds with diiiiculty as it comes in lumps of l all shapes and forms, and it is essential 'that all useless pivots, plates, levers; etc., be eliminated, as the carbid is apt to work' in between such parts and prevent the appa-A ratus from properly Vperforming its.' work. This ditiiculty has been eliminatedb'y pro vriding a minimuml number of Y pivots Vfor freedom of action. v

Another object of the invention is to pre'- vent packing and clogging of carbid within the' carbid hopper orcontainer, thereby in! suring when the feeding means are in discharging position.

The invention also has for its object to provide ar moisture-proof feeding means to prevent'after-generation of gas which isa continuous loss, and also to prevent'slal ing and faking of carbid in the hopper or on the dumping pan which also results in a waste of gas and causes anfirregular feedof 'arbid M Gther objects and advantages of the invention will be pointed out in the detailed description appearing` hereinafter, and in order that Vthe same may be better understood, reference is had to the accompanying drawings, forming a part of this specication.

` In the drawings,`

Figure l is a vertical section of the apparatus;

Fig. 2 is a sectional view of the carbid feed mechanism showing the same in discharging position;

Fig. 8 is a view similar to `Fig. 2 showing, the feed-mechanism closed, and

Fig. #l is a section on the line 4 4 of Fig. 3.

Referring specifically to the drawings, 5 denotes a carbid reservoir having a hopper specification of Letters Patent.

bottom 5? provided with a contracted portion at the center open at the bottom and slightly to one side so that the carbid is not discharged straight down but sidewise. The opposite side walls 5b of the contracted portion are parallel, the rear wall 5c follows the'slope of the hopper bottom 5a, whereas the front wall 5d has an outward curve and terminates short of the bottom of the wall 5C to leave the opening through which the carbid is discharged into a pan 6 positioned beneathsaid opening. rlhis pan has a curved bottom and upstanding side walls 6a, the latter being located on the outside of the walls 5". V,The pan bottom extends at one end to the top of the side walls 6a with a curve corresponding to the curvature of the` wall 5, as shown at 6b, to tit slidably on the outside of said wall. rllhis end of the pan has a hollow extension 'T adapted to be weighted as shown at 7a. The other end of the `pan is open, this end being the discharging end,'and when the pan is in non-discharging position said end seats against an inclined wall orstop plate 8 carried by and (fleoeiicliiig from the hopper bottom 5a. ThisV plate is faced .with a tapered plug 8a adapted to enter the pan end completely close the discharge end thereof as Vshown in Fig. Beneath the plug 8a,the plate 8 is faced with a gasket 8" which projects beyond the edges of the plug, the edges of the pan enga ging the projecting portions Aof the gasket to Ymake a tight joint. The sides 6a of the pan vcarry packing strips 9 which slidably seat against the outer faces of the walls 5". lt will therefore be seen that the pan 6, when in non-discharging position, completely seals the carbid .outlet of the hopper against the entrance of water or moisture, the curved end wall 61 snugly fitting the Vwall 5d as hereinbefore described. The carbid in the reservoir is therefore completely shut off from moisture, and consequently prevented from slalring or caking. Y

' 'The pan 6 lis pivoted on a shaft l0 pass` ing across and through the wallsb and into the side walls 6a of the pan. `The pivot rod is made fast to the walls 6 so that it turns when the panswings, and it has inside the walls 5 a crank bend l0a to which is attached an agitator rod 10b extending upwardly into the hopper 5, whereby the carbid is stirred or agitated every time the pan operates. The agitator rod also has bottom extensions l0c which project into the pan 6 so that' when the latter swings down to discharging position these extensions move forward and prevent thewcarbid banking on the pan, thereby assuring a uniform feed at all times. The upper end of the rod 1()b is loosely connected by a link 101 to a support 10e on the bottoinoi1 a conical shield 11 inthe hopper 5 above the outlet of the latter. to carry the weight of the carbid and prevents itfrom bearing too hard on the pan 6 when the latter is in receiving and nondischarging position. The shield 11 is supported by legs 11a from the wall of thev hopper bottom 5a.

-The side wall of vthe carbid reservoir 5 is continued below the liopperbottom 5a,

. andits lower end is open and dips into the water in a tank 12, being supported in said tank by legs 13." The carbid is discharged by the pan 6 into this water, and to facili tate the escape of the gas, the bottom of the reservoir wall 'which is immersed in the f water has escape apertures 14.

The reservoir 5 is surrounded byva cylindrical wall l5 which is spaced from the wall of the tank 12 and is joinedv at the bottom to the latter as shown at 15a. ln the space between'the wall 15 and the wall ofthe tank- 12 Yextends a gas bell 16, the usual water seal 16.a being provided. The gas ris- Y ing'romihe water in thebottom of the tank`12 passes upwardly through the space lbetween the reservoir 5 and the wall 15 andV then' passes into the bell 16'as usual. The bell 16 has rollers 17 running on the inside of the wall of the tank 12, and serving to hold the bell properly centered and preventing it from sticking. i

The carbid dumping` pan 6 is operated by the rise and fall of the bell 15.V sshown in F ig. 1, the bottom extension of the reservoir 5 supports a lever 1S havingl one end connected by a link 18a to the pan, and to the other endof the lever is connected an upright'slidable rod 18 supported ina bearing 19 at the top of the reservoir. The rod isp'ositioned at its upper end above the topV as Lshown inF ig. 2. When the bell 16 again i rises and releases the rod 18h, the pan auto- This shield helps a service, pipe 21, the latter also having a kconnection 21 with the lower portion of the'ta'nk 12, soV that when any moisture or water gets in the pipe it will drain into the generating chamber. From` theV pipe. 2l leads a pipe 22 which Vcarries the gas to the placejof use. rThe pipe 22 is provided with a valve 22il which is closed when the apparatus is being replenished, in order to prevent the entry of air into the pipe line, which would cause flickeringY and buzzing of thel lights; To the pipe 21 is also connected an exhaust valve 23 to let out all air which may have gathered in the vbell 16 or other parts of the apparatus after it has been replenished with water and carbid, and

started.

The `tank 12 has a cover 24 provided with air-vent holes 25 to leave air in and out as the bell 16 lowersand rises.

It will be noted.; in Fig. 3 that botten ofA the pan '6V is curved in such a manner that when its discharge end seats against the stop plate 8, and before arriving in this position, the bottom assumes a downward slope V:trom this end, with the result that the carbid rollsV down and .awayiromV the dis charge end topreclude the possibility oi the carbid preventing the entrance of the plug .83

A pump 26 is connected to the tank 12 for removalof the sludge accumulations.

I' claim:

1. In an acetylene gas generator, a carbid reservoir having an outlet, a swinging pan positioned over the outlet, a pivot rod i'or the pan movable therewith and extending' across` the outlet end 'of Vthe reservoirsaid. rod having acrank, and a carbid agitator connected to the Vcrank and extending upwardly into the reservoir.
