Fi liiGis' '11 detail Vertical sctiq'n milieu ii hilili form a gradually t'apering my. a l 0 Ill] by a spring 33 in the casing 31 which tends to force the diaphragm downwardly and, controls a valve 34 to which the diaphragm is connected by a stem 35. Valve 34 is disposed in a gas channel 36, between valve seats 37 and 38 which respectively open into the regulator pipes 39 and 40, the parts being so arranged that with normal pressure through the outlet pipe 29 below the diaphragm 32, valve 34 will be held as shown,

in Figure 8 free of both of the valve seats,

3? and 38 and thus gas will pass through both of the regulator pipes 139 and 40.

"lVhen pressure falls below the desired point, spring 33 will act to depress the diaphragm and thus lower valve 34 onto the lowermost seat 3?, cutting oil the flow of gas through the regulator pipe 39 and deflecting all of the gas through the regulator pipe 40. On

,phragm 32 against the tension of its spring,

the other hand should the pressure increase ticularly or wall 50 having adjacent to its upper end an spoiling 53 through which the gas passes downwardly beneath a baille plate 54 car ried by and spaced from this partition or wall, causing the gas to thus take a tortuous path and finally emerge from beneath the baffle plate 54 at a point where it will be forced to pass through the full body of the filtering material 52 before tin-ally passing outwardly through the service valve 5i.

The carbide feed valve 19 is engaged within the valve casing 13 by the upper, lyoke shaped end of an arm 55 as seen pararm being secured upon a short shaft 56 which projects outwardly through the wall of the valve casing and has secured thereto above the desired point this pressure will cause upward flexing movement of the d1a-,

and will seat valve 34 against the upper seat 38 so as to cut oil the flow of gas through the regulator pipe 40 and force the gas to pass solely through the pipe 39.

On the water casing 10 at one side of the valve casing 13 beyond the gear 20 of shaft 18 is mounted an upright filter casing 41 whose lower enlarged portion forms a chamber for a rotor 42 having concavoconvex v peripheral blades 43 acted upon by-the gas rising through water 44 in. the filter casing from the lower end of the regulator pipe 40,

the lower end of a lever 57 shown in Figures in Figure 5, the lower end of this y 2 and 6. This lever is engaged upon the ex- H terior of the valve casing 13 by one hook and of an adjusting screw as, extending through an outstanding lug 59 of the valve casing and provided with a threaded adjusting nut 60 so that the valve l9 may thus be held in fully closed position against the inner end of the elbow 14- while the generator is being transported from place to place.

In addition to the above described parts which render the generator proposed by my invention of a compact, strong and durable nature as a whole, adapting the same to which enters the lower portion of the filter casing and is in communication with a charrncl 40 opening below the rotor, which channel may receive a drain cock 40* as best seen r in Figure 3. This filter easing has a groove in one side wall forming a gas lay-pass chair, nel 4 5 with the lower end of which the regulator pipe 39 communicates. The upper end of this groove or channel terminates above the level of the water 44 which is supplied to the casing through a valved filling device 46, the level being determined by a valved overflow cock 47. y The shaft 48 of the gas actuator rotor 42 extends laterally through, the inner wall of.-

the filter casing 41 as shown in Figure 4 and is provided with a small gear wheel 49 in mesh with the gear 20 of the feed shaft 18 'tube 61 secured diametrically therethrough for the reception of a bar to be utilized as a handle so that two persons, one upon each,

ready portability, the tanlrlO may have a side of the generator may readily carry the same from place to place.

In operation, the opening of the valve 19 and of the gas outlet valve 30, permits of ,the formation and passage of gas through 1 the gas outlet pipe 39 and into the regulator casing 31.

At this time the diaphragm 32 will be in lowered position with the valve 34 cutting off the .lator pipe 39.

iassage of gas to the reguaround the rotor 42! so as to start rotation of the latter. of rotation of the rotor the feed of carbide downwardly through the valve casing will take place by virtue of the rotation of the feed member and the normal operation will then begin. When pressure of gas is built up sufficiently the regulator diaphragm 32 I hus all ot the gas will be .forced to pass through pipe 40 and upwardly Immediately upon the start will be elevated and part of the gas will flow through the by-pass channel 45 as pre viously described and when there is an over flow supply of gas at any time pressure will seat the valve 34 so as to close the pipe 40 leaving all of the gas to .fiow for the time being and until the pressure again drops to,

normal, through the by-pass channel 45.

By the above described construction I provide an acetylene as generator which will be safe, strong and durable and will at the same time be compact and readily portable, especially adapting the same to garage and service station uses as well as other uses where acetylene gas in small steady quantities is desired.

I claim:

1. In a gas generator, a fluid casing having an upper carbide intake, a valve casing secured over the intake, a carbide container, a feed elbow having vertical and horizontal portions, the vertical portion of which supports said container and the horizontal portion of which opens laterally into the valve casing and has an annular lip projecting inwardly beyond the walls of said valve casing forming a valve seat, and an internal balfie member across its upper portion and spaced from the valve casin a valve in the valve casing shiftable towar and away from said seat and adapted to control the flow of carbide from the elbow, a shaft extending through the valve casing and axially through the horizontal portion of the feed elbow and upon which said valve is loosely guided and movable, and a feed member secured on and rotatable with said shaft in the feed elbow between the said baflle member and the valve casing, said feed member consisting of spirally curved feed arms rigid at one end with the shaft and tapering to relatively sharp free ends as described.

2. In a gas generator, a fluid casing having an upper carbide intake, a valve casing secured over the intake, a carbide container, a feed elbow having vertical and horizontal portions, the vertical portion of which supports said container and the horizontal portion of which opens laterally into the valve casing and has an annular lip projecting inwardly beyond the wall of said valve casing forming a valve seat, and an internal bafile member across its upper portion and spaced from the valve casing, a valve in the valve casing shiftable toward and away from said seat and adapted to control the How of carbide from the elbow, a shaft extending through the valve casing and axiall through the horizontal portion of the feed elbow and upon which said valve is loosely guided and movable, and a feed member secured on and rotatable with said shaft in the feed elbow between the said baitle men1- ber and the valve casing, said feed member consisting of a pair of feed arms, ri id at one end with the shaft at diainetrical opposite points, each of said arms in spirally curved around one half of the circumference of the shaft in spaced relation thereto and tapering throughout its length to a sharp digging point diametrically opposite to its end connected to the shaft.
