. ACETYLENE -GAs GENERATOR.

SPEGIFICA.TIOIT forming: part of Letters Patent No. 752,053, dated February 16, 19O4=.- Application filed June 4, 1902. Serial No. 110,131. (No model.) I

Toall whom it may concern:

Be it known that I, ALFRED C. EINSTEIN, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Acetylene-Gas Generators, of which the follow-ing'is a full, clear, and exact d'esci'iption, reference being had to the accompanying drawings,frming part of this speci- My. invention relates to that class of gasgenerating apparatus utilized in the production of acetylene gas from calcium carbid,-the invention having for its object the production of a generator in which a normal pressure and amount of gas will be maintained, due to the construction and arrangement of the waterdelivery parts of the apparatus and the con-- vnection of the gas-conveying pipes in such manner that the .gas evolved in the apparatus constantly acts to regulate the amount of Water fed to the carbid;

- subdivided by partitions 3 and 4. The parti tions 3 and i are united by a central tube 5, and the partitions divide the interior of the tank' into three chambersviz. a generatingchamber 6, in which the carbid is contained, a water-chamher7, from which the water is conveyed to be delivered into the generatingchamber, and a gas-chamber 8, into which the gas passes as it is produced in the generatingchamber. l 4

9 designates a water and gas conducting tube seated. in the tube 5 and extending from the generating-chamber to the gas-chamber, the tube being open at both ends to communicate with said chambers.

10 designates a water-feed pipe provided with legs 11 and 12, that are open at their ends service.

that water in said chamber may enter the legs to pass upwardly through the feed-pipe. The

feed-pipe is preferably inclined upwardly from one of the legs, and it is positioned the conducting-tube 9 and provided with a restricted outlet-nozzle 13, through which the water finds egress from the feed-pipe into the conducting-tube to descend therethrough onto the carhid in the receptacle 2. 4

14 designates a supply-tank provided with 'an inlet 15, closed hy a cap 16.

17 is a supply-pipe provided with a valve '18 and leading to the tank 1, to which it is connected at the bottom of the water-chamber 7 19 is a drain-cock fitted to a supply-pipe 17.

- 20 is a relief-pipe connected to the supplypipe 17 below the valve 18, that is positionedin said pipe and extends upwardly into the supply-tank l tto' the upper end of said tank. 21 is a blow-off at the top of the supply-tank. 22 is a gas-delivery pipe leading from the upper end of the generator-tank l and having to communicate with t-ldilttithf-ohamber '7, so

and introduced into said tank at the upper end of the waterrchamber 7.

' In the conducting-tube 9 I provide one or more orifices 9, through which the condensed water resulting from vapor that rises into the gas-chamber 8 from the generating-chamher may be returned to the generating-chain her on falling to the dished partition i, which constitutes the bottom of the gas-chamber.

'In the practical use of this generator carbid is placed in the receptacle 2 previous to its being afiixed to the generator-tank, and on the application of the carbid-receptacle to the tank the apparatus is in condition for Water is introduced into the sup ply-tank 14: through the inlet 15 and passes therefrom through'the supply-pipe 17 to the Water-chamber 7 in the tank 1, the amount of water introduced being governed by the 10.-

cation of the inlet, which ispositioned sothat the supply-tank will be only partially filled when-the water-chamber is full. When the desiredamount of water has been introduced, the valve 18 may be closed to shut off the passage of water from the supply-tank to the water-chamber until such time as may be desired to eflect generation of gas. On the opening of the valve 18 the water contained by the supply-tank descends through the supply-pipe 17 and enters the water-chamber 7, with a result that it rises through one of the legs 11 or 12 of the feed-pipe to escape through the restricted outlet-nozzle 13 and descendsthrough the conducting-tube 9 into the generating-chamber onto the carbid in said chamber; While I have shown the feed-pipe 10 as provided with two legs, I do not limit myself to the use of both of these legs, as one of them would be ample under fnany conditions. By the delivery of water to, the carbid in the manner explained generation of gas is produced and the gas passes from the generating-chamber through the tube 9 into the gas-chamber 8and generation being continued without cessation so long as excessive pressure is not produced. In the result of excessive pressure of gas the gas after passing into the conveying-pipe 22 returns to the generator-tank through the return pressure-pipe 24 and enters the water-chamber 7 'to exert pressure against the water in'said chamber. In such case the water in said chamber is driven downwardly therein by the pressure of gas and ascends through the supplypipe to be returned to the supply-tank 14, thereby loweringit away from the leg or legs of the feed-pipe 10 and causing cessation of I delivery of water through said feed-pipe.

The pressure of gas holds the water in the chamber 7 away from the feed-pipe until the gas-pressure again becomes'normal in the gas-chamber 8, when upon reduction of pressure the water returns to the water-chamber and delivery through the feed-pipe is again established as before to renew the generation of gas.

In the'event of excessive pressure of gas occurring after the apparatus has been shut ofi' by the closing of the valve 18, that controls the supply-pipe 17, the excessive pres sure may find egress from the water-chamber 7 by passing through the water therein and through the supply-pipe 17 to the relief-pipe 20, through which it is delivered into the supply-tank 14 to escape through the blow-off or safety valve 21.

I claim as my invention i 1. In an acetylene-gas generator, the combinatio n of a generating-chamber, a waterchamber, a gas-chamber, a tube prov idingcommunication between said generating-chamber and said gas -chamber, a feed-pipe having a leg arranged in said water-chamber and seated in said pipe, an outlet-nozzle on said feed-pipe in said tube, a supply-tank, a supply-pipe leading from said supply-tank to said water-chamber, a gas-conveying pipe leading from said gas-chamber, and a return-pipeleading from said gas-conveying pipe to said water-chamber, substantially'as and for the purpose set forth.

2. In-an acetylene-gas generator, the combination of--a generating-chamber, a'waterchamber, a gas-chamber, means for delivering water from said water-chamber to said generating-chamber, a water-conveying pipe leading from said gas-chainber,a return-pipe leading from said gas-pipe to said water-chamber,

asupply-tank,asupply-pipeleading from said 8o.

supply-tank to said water-chamber, and a relief-pipe leading from said supply-pipe into said supply-tank, substantially as described.

3. In an acetylene-gas generator, the combination of a generating-chamber, a waterchamber, a gas-chamber, a tube providing communication between said generating and gas chambers,- and provided at the bottom of said gas-chamber with an orifice, a water-feed pipe leading from said water-chamber to said tube and having an outlet'arranged in said tube, substantially as described.
