and claimed.

In the accompanying drawings :--Figure' 1 is a vertical section of the generator. Fig.1 2 is a section taken on line 2-'2, of Fig. 1. Fig. 3 is a section taken on line 3-3, of Fig. 1 looking in the direction, of the arrow. I Fig. l is an enlarged vertical sectional view through the piston casing. F ig. 5 is an enla-rged sectional view through the upper end of the piston casing showing the manner of the carbid reeeptacle so as to come in contact with the carbid contained in the upper tank. It should 'be understood, however, that the present device is adapted for use in houses and for other purposes and may be modified as to itsdetall mechanical construction without from the spirit of the invention. v Referring to the drawings will be seen 55 as 1 tee-the use of'the 'generator tained in the bottom of the tank. (The providing the gas chamber should be overextends downwardly into the liquid within With these and other objects view this I invention consists of certain novel combina- I' holding the piston rod in a set position.v Fig. -6 is a perspective view of the upper -mean s such as illustrated at 11 for the'pu-rprevent the splashing of liquid or'water into which comprises a tank shape body having a flared bottom 2. This bottom 2. is provided at its lower end with a clean-out opening '3 to ifiacilitate the cleaning of the bottom of the receptacle when it is so desired. I The base or water'containmg tank 1 is provided with a substantially inverted cone-shape hopper {l which is open at its lower end as indicated at 5 and over this opening '5 is placed a substantially domeshape shield 6, which shield is supported above (the inner face of the hopper a by means of upwardly extending legs '7' so as to allow the [carbid to readily slide into the water or liquid conliquid or water is adapted to be placed in the tank 1 at a sufficient height to extend slightly above the lower end of the 'hopper, r and in view of the fact that the hopper 4 '75 the tank l, it will be seen that this willprevent the splashing ofthe liquid in case the body of the generator should be su-bjectto sudden jars as would be the case when used 831) course, it should be understood that "the water containing tank or base '1 may be prov-ided with any suitable filling opening." H

A carbid containing section or compartment 8 is detaohaibl y mounted upon the upper end of the base 1 and is provided with a circumferential flange- '9 upon its lower end :to fit tightly around the upper edge of the .basel. A' sealing washer 10 is interposed between the .carbid' containing receptacle 8 and the "base 1 so as to constitute -anair,'gas and water tight joint between the two sections. The carbid containingjsection 8 may be provided with-any'suitable pose of allowing the device to be attached to any desired support such as a vehicle or automobile frame. The carbid containing section '8 is provided at-its upper end with an upwardly extending collar 12 upon which is threaded a removable cap '13 so as to nbrrnally close the -"upper end of the carbid containing section 8. "lhis 'cap' may, illOW- ever, be removed when it is so desired.

A pressure gage 5L4 may be earriediby the carbid containing section 8 so as to indicate the amount of gas pressure within the base 1 if i h .1'1 ejs A g s pni y pipe. 16 is eonnected to the carbid contain as to communicate with the base 1 to allow the passage of acetylene gas from the generator.

A carbid delivering hopper 16 is mounted 5 within the carbid containing section 8 and comprises a substantially inverted coneshape body having an open lower end 17. A transversely extending guiding bar 18 is carried by the hopper 16 and this guiding bar 18 is provided with an eye 19 through which the vertically extending guiding rod 20 passes. This guiding rod 20 carries a helical twisted agitator bar 21 which bar 21 terminates in a valve 22 at 15 its lower end. This valve 22 has a depending pin 22, and this pin 22 is pivotally connected to the link 23 by means of a pivot pin 24 or may be connected in any desired manner without departing from the spirit 2 of the invention. The carbid is placed within the upper end of the carbid containing section 8 through the opening which is normally closed by means of the cap 13, and the carbid' is delivered from the hopper 16 2 through the opening 17 when the valve 22 is moved away from the opening 17 to the position shown in full lines. One end of the link 23 is pivotally connected to a suporting rod 25 which constitutes a suspending'ineans therefor, and the opposite end of this link 23 is provided with a longitudinallyextending slot 26 which slot receives a transverselv extending pin 27 carried by the vertically extending piston rod 28. The piston rod 28 is in this manner s curely held in engagement with the link tions 31 to admit the gas from the base 1 into the lower end of the piston cylinder 29. The piston rod 28 passes through this cap 30 and is provided with a reduced upper end 32 which passes through the piston head 33. This piston head 33 is loosely mounted upon 59 the piston rod 28 and is normally -forced into engagement with the beveled shoulder 34 of the piston rod by means a of a tension spring The tension of this spring 35 may be adjusted by means of a nut 36 which is threaded upon the upper end of the piston rod 28. The piston head 33 may of course be formed of any desired construction for the purpose of performing the desired function. The lower end of the rod 28 is bifurcated so as to straddle the link 23 similar to the manner in which the depending pin 22 straddles it as is illustrated in Fig. 8. A coil spring 37 is mountedupon the lower end of the piston rod 28 and is interposed between the cap 30 and an adjusting nut 38., which 2.61--

justing nut 33 is threaded upon the lower end of the piston rod 28 for the purpose of regulating the tension of the spring 37 The piston cylinder 29 and section 8 are provided with registering apertures 39 which registering apertures will allow the escapement of excess mulated in the base ii The agitator bar 21 is provided with a toothed periphery 40, which will break up the agglomerated lumps of carbid as the agitator bar passes through the carbid and inthis manner cause only small particles of carbid to drop into the base 1, thereby allowing the acetylene gas to be more.

quickly generated than if large particles of ca'rbid were allowed to drop into the base 1.

From the foregoing description it will be seen that when the valve 22 is drawn away from the opening 17 the carbid with-' in the carbid containing section 8 will drop into the base 1 and by mixing with the water within the lower portion 2 of the base 1 will cause acetylene gas to be generated and as the gas continues to'be generated the piston head 33 will 'be forced upwardly thereby drawing the valve 22 to a closed position over the opening 17. In case the gas should continue to be generated at an excess pressure the piston head 33 will be "forced still farther upwardly against the ten sion of the spring 35 and cause the piston head 33 to pass beyond the apertures 39 thereby permitting the discharge of excess gas from i the generator. As soon as suflicient gas has escaped from the generator the piston head will assume itsnormal position and when sutlicient gas has been used from the base 1,

the piston will again drop in the piston cylinder 29 suflicient to cause the valve 22 to be drawn away from the opening 17.

The piston rod 28 carries at its upper end an eye 41 which eye is adapted to receive the downwardly inclined end 42 of the loclring rod 43. This locking rod 13 passes through a guiding sleeve 14; and carries a knob 45 at its outer end to facilitate the op eration of the locking pin or rod -13. When it is desired to hold the valve 22 in a closed position such as for instance when the carbid containing sectionB is being filled with the carbid the piston rod 28 is raised to the position shown in dotted lines in Fig. 1., and the downwardly extending end 42 of the pin or bar 43 is forced through the eye 4.1 thereby holding the rod 28 in a set position and also holding the valve 22 in firm engagement with the edge of the aperture 17. Owing to the fact that the inner end 12 i of the rod 43 is inclined downwardly it willbe seen that the farther the pin or rod is is pushed inwardly, the rod 28 will be drawn farther upwardly.

It, of course, should be understood that gas which has accuwhen it is desired to fill the carbid receptacle 8, the cap 13 may be removed therefrom so as to allow the operator to place his hand into the carbid receptacle 8 and pull upwardly upon the rod 20 and in this manner raise the plunger 33 to such a position as to allow the locking rod L3 to engage the eye carried by the valve stem 28.

It will be seen that a very simple and eflicient locking means for the piston rod 28 has been produced, whereby the valve 22 may be firmly held in a closed position.
