JOHN WILLIAM HOLTBY, OF JUNCTION CITY, KENTUCKY.

ACETYLENE-GAS GENERATOR.

Application filed April 20, 1915.

T all whom it may concern:

Be it known that I, J OHN \V. HOLTBY, a citizen of the United States, residing at Junction City, in the county of Boyle and State of Kentucky, have invented a new and useful Acetylene-Gas Generator; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved acetylene gas generator, and an object of the invention is to provide means for auton'iatically governing the carbid in its feed, in order to maintain uniform pressure of the gas and the gasometer bell.

Another object of the invention is the provision of means for automatically closing the valve of the main carbid receptacle, in case the valve gearing should become disconnected from the gasometer bell.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

in the drawings :Figure 1 is a vertical sectional view. Fig. 2 is a-sectional view on line 3-3 of Fig. 1. Fig. 8 is a transverse sectional view on line l4: of Fig. 1. Fig. 4 is a transverse sectional view on line 5--5 of Fig. 1. tive view of the connections between the lever 40 and the arm 26, showing the bracket arm 30, to which the member 32 is pivoted.

Referring to the drawings, 1 designates the water tank, the bottom 2 of which is formed with an extension auxiliary bottom 3, which is conical as shown at 4, so that the sediment or refuse may become centered. By opening the valve 5 the sediment or refuse may be carried off through the pipe 6. The tank 1 is provided with a door or closure 7, which when closed engages a suitable gasket 8, so as to make a tight fit, in order to prevent the escape of water in the tank. This door or closure is provided for the purpose of permitting the tank 1 to be cleaned, without disarranging the other parts of the generator.

In the present instance the tank 1 is supported upon suitable legs 9 secured at 10 to the tank. Upon the inner circumference of the tank are T-shaped guides 11, which Specification of Letters Patent.

are engaged by the guide brackets 12, which are secured to, as at 13, and carried by the gasometer bell 1 1, vhich, as the gas increases and decreases correspondingly to the consumption thereof, rises and lowers in the tank 1. The gasometer bell in its vertical movement is maintained plumb and concentric with the tank 1 through the medium of said guides. Secured at to the bottom 2 of the tank 1 are vertically disposed bracket standards 16, the upper ends of which are secured at 17 to the carbid receptacle 18, which is shown as rectangular in shape or contour and provided with a pyramidal bottom 19, so that the carbid will pass through the outlet rectangular pipe 20, which is provided with transverse openings 21. Guided in said openings is a valve bar 22 having a valve opening designed to be thrown in and out of registration with the passage through the outlet pipe. This valve bar is guided at 24 in a cross piece 25, which connects two of the bracket standards. The valve bar is provided with a downwardly extending arm 26 having a slot 27.

Connected at 28 to a cross piece 29 (which connects two other bracket standards) is a bracket arm 30, and mounted to operate on a pin 31 at the upper end of the bracket arm is a member 32 having an arm 33 having a pin 34: extending into the slot 27 of the arm 26. This member 82 is supplied with two additional arms 35 and 36 disposed to appear wish-bone fashion. Also secured at 28 to the cross piece .29 is another bracket arm 38, to the upper end of which as at 39 a lever 40 is pivoted. One arm of this lever 40 has a pin &1, designed to play between the wish-bone arms or prongs 35 and 36, in order to oscillate the member 32 in one direction or the other. Connected to the short arm 42 of the lever l-0 is a link 43, which in turn is pivoted at 4 1 to the rod 45, which passes through the upper part of the gasometer bell. This rod 45 is threaded, and extends through a bracket 46 (which is secured at 47 to the top of the gasonieter bell), there being nuts 48 above and below the bracket 46 whereby the rod 15 may be adjusted, so that the connections between the gasometer bell and the oscillatory member 32 may be varied. In case the link 43 and the rod 45 become broken or otherwise disconnected, suitable means 50 is provided for automatically closing the valve bar, in order to shut off the flow of the car-bid from the receptacle 18. The gasometer bell is limited in its movement vertically by the chain 51, which connect the tank 1 and the gasometer bell, as shown clearly in Fig. 1. A suitable extension pipe 52 is connected at 53 to the top of the gasometer bell, which pipe 52 is in turn connected to the valve casing 54- having a valve 55, and connected to the valve casing 54., is an auxiliary carbid receptacle 56 having an extension pipe 57 and a valve casing 58 provided with a valve 59. When the receptacle 56 needs replenishing, the valve is closed and the valve 59 is opened, and a suitable funnel (not shown) is inserted in the valve casing 58, and the carbid (which may be nut or crushed carbid) is poured into the funnel, from which it empties into the receptacle 56. In starting the machine both receptacles 18 and 56 are filled with the car-bid, and when the carbid in the receptacle 18 is consumed, the valve 55 is opened, thereby permitting the carbid in the receptacle 56 to empty into the receptacle 18, at which time the valve 59 remains closed, to prevent the escape of gas. After the receptacle 56 is emptied into the receptacle 18, said receptacle is replenished in the man 'ner heretofore stated, As the gas generates in the gascmeter bell it is carried off through. the outlet pipe 60, for the purpose of consumption. l Jhen the quantity of gas in the gasometer bell is greater than the consumption of gas, it is relieved by means of the exhaust pipe or tube 61, which extends through the top of the gasometer bell and is provided with valve 62. This exhaust pipe 61 terminates a short distance above the lower edge of the gasometer bell, and when the bell rises and the volume is greater than the consumption, the lower end 63 of the exhaust pipe will assume a position above to the level of the water, thereby allowing the excess of gas to escape.

The invention having been set forth, what is claimed as new and useful is In an acetylene gas generator, a main tank, a gasometer bell guided telescopically therein to rise and lower vertically, a gas outlet pipe, a carbid receptacle, a supporting frame upon the interior of the tank to support the carbid receptacle in the interior of the bell, said cal-bid receptacle having an outlet tube at its lower end, a valve bar controlling the carbid passing through said tube and having a right angled extending slotted arm, a pair of brackets secured to the supporting frame, an oscillatory member fulcrumed to one bracket and having an arm connection to said slotted arm, so that as the member is oscillated, the valve bar is moved transversely of the outlet tube, spring tensioning means against which the oscillatory member is moved to open the valve bar, said oscillatory member having a pair or wish-bone disposed arms, a lever pivoted to the other bracket and having a pin playing between said wish-bone arms, a connection between saidlever and the gasometer bell, said spring tensioning means acting to operate the oscillatory member to close the valve bar in the event said connections between the lever and the bell become disabled.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
