,lQrodzz-aam-tat mm; Be it known t at I, F ,',en-' gineer, citizen of theFrench Republic, re-

. siding at Paris,- in the Department Y of the 5 Seine, France, have invented a certain new and I useful 3 AcetyleneGe'nerator," of which i the following isa specificatioin This invention relates to apparatus" for generating acetylene for the production of '10 lightfor projectors, in kinematograph lanterns or for other purposes; or for the production of heat as, 'for example,- in autogenous soldering,

acetylene generator, as hereinafter set forth and particularly pointed out in the claim.

In the accompanying drawings, Figure 1' shows the acetylene generator invertical t in plan.; Fig.- 3 shows a. vertical section of the uppenpart.

. of the generator taken along'the hne A'A section. Fig.2 illustrates of Fig. 2. l

1 The acetylene generator shown in Figs. 1,

2 and 3 comprisesan outer receptacle 1 to;

which is fixed an inner recep the bottom'o tacle 2; through the upper end of both of these receptacles passes a third receptacle 3. This receptacle is normally water and air tight, exceptat the small opening 9 formed in the lower tubular extension 4. The upper part of the receptacle3- isprovided with a lid 5 which may be hermetically-closed by 'means of the stirrup orbail 6 and the 'screw7. v

The annular space between the receptacles 1 and 2 is, when the apparatus is in use, filled with water for the purpose of'cooling the generator, such water being introduced through an opening furnished with plug or stopper 8.

In use, the receptacle 2 contains a determined quantity of water which is intro duced by being poured into the receptacle 3,. whence it flows 1nto receptacle 2 through the;

of the receptacle- V small opening 9. Theto 2 is connected by thetu e 10' to a safety valve 11 and to a cook or valve-12, through which, when desired, air may be forced .un-

The upper end of the receptacle 1 carries a rtlcal tube 13 which is closed at its lower The upper part of the tube 13 communicates lateral t11l 1es 14 and 15 with valves 16 and, :1 through WhlCh valves communication is opened respectively with the upper-part ofthe receptacle 3 and the upper part of the GI receptacl'e2 by tubes18 and 19. Gas enteringthe tube 13 either through tube 18, valve 16, and tube 14, or through tube 19, valve 17 and tube 15, passes through the purifier 20 placed within the receptacle 3. When the water is forced into and rises in the recep- .tacle 3, the cat-bid is attacked and acetylene .lsgiven oflt' andpasses through the tube 18, the valve 16 being open and the valve 1 7 being closed. The gas thus generated and conducted passes through, the purifier 20 and the valve 21. The ascentof'the water .in the receptacle 3 is effected by 8. the pres. sure in the receptacle 2 as long as this pressure is greater than that of thelgenerated When it is desired to stop the generation of gas the valve 17 is opened so as to establishcommunication for a moment between and'equalize'the pressure, in receptacles 2 and'3; The valve'16 then closed. The

The valve 21 being closed in its turn gas accumulates'in the receptacle 2 and sets'np the 7 essure therein necessary for the nextworkmgof the. pparatus after rez pg ragi the valves 16 and 21.

Having thus described my invention, what Iclaimis:-

An acetylene generator comprising a closed vessel adapted to contain a body of liquid and also to hold gas under pressure, an inner closed receptacle in said vessel having its lower end provided with a small opening below the normal level of the liquid,-

a removable container in said receptacle having its lower end adapted to admit liquid but supported above the normal level of the liquid in with the inner the upper valves in said tube and pipe, a delivery pipe the vessel,a tube communicating receptacle, a pi econnecting end 'of said vessel with said tube,

connected with said tube between said valves, and means whereby pneumatic pressure mav-be' brought to bear upon the sur-
