Specification of Letters Patent.

Patented June 17, 1913.

Application filed May 13, 1911. Serial No. 627,018.

To all whom it may concern Be it known that I, NEWTON J. ANDnnsoN, a citizen of the United States of America, residing at Coffeyville, in the county of Montgomery and State of Kansas, have invented certain new and useful Improvements in Acet-ylene- Generators, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to the subject of producing gaseous fuels for use in connection with welding and other tools, and the principal object of the same is to provide a producing plant in which acetylene gas can be generated, the plant being equipped with certain safety devices as hereinafter described.

iVith the above and other objects in view, this invent-ion consists in general of certain novel details of construction, combination and arrangements of parts, as will be hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and Figure l is a front elevation of the improved generator. Fig. 2 is a partial plan view showing the upper portion of the carbid receptacle and the safety appliances. Figs. 3 and t are detail views partly in section showing the means for locking the safety valve operating arm. Fig. 5 is a fragmentary plan View of the valve operating arm, certain of the parts being shown in sect-ion. Fig. 6 is a vertical section of the safety valve. Fig. 7 is a view at right angles to Fig. 1 showing the upper part of the device.

The improved fuel generating plant is of special utility in the production of acetylene gas for use in connection with the type of welding torches shown in U. S. Letters Pat ent No. 976,717 granted to me November 22, 1910.

The improved acetylene generator comprises an acetylene tank 23 which is rigidly secured to a platform 24, said tank being preferably cylindrical. At its lower portion, the tank 23 is provided with a cleanout opening from which a tube 27 projects laterally. A flanged cap 29 fits snugly over the outer end of the tube 27 to control the same, and on this cap 29 is provided a hand grip 32 preferably in the form of a wheel so that the latter may be screwed on or ofi the tube.

At a point above the bottom, the tank 23 is provided with an opening from which an elbow 34; projects outwardly, said elbow carrying a trap 35 which forms a liquid seal to prevent air entering the tank 23, and from said trap extends a vertical pipe 36 carrying on its upper end a valve casing 37 which has its inlet end provided with a coupling sleeve 38 into which projects a funnel 39 so that the tank may be charged with water. As will be obvious, the funnel 39 is but one of the many ways in which water can be placed in the tank through the pipe 36 since the coupling sleeve 38 is capable of being used with any type of tubular water-conveying devices.

A flanged cover 40 is rigidly fastened in overlapping gas-tight relation to the upper edge of the tank 23. A carbid receptacle -12 is provided with an outstanding flange 44 arranged to overlap and seal the joint between the cover and the receptacle of the gas-tank. On this receptacle is a cap 53 and an operating rod 55 is slidable through the cap 53 and has its projecting upper end provided with a bifurcated head 56 in which a rocking lever 57 is pivotally mounted. This lever has pivotal connection by means of a link 57 wit-h an upstanding ear 58 carried by the carbid receptacle. The other end of said lever is provided with an eye 59 which is engaged by the end hook 60 of the handle 61 preferably formed with a triangular hand grip 62. A spring 62 is coiled about the rod 55 and has one end bearing on the head 56 and the other end bearing on the cap 53 so that the rod 55 is normally retained in an outwardly-projected position.

The cylindrical washing tank 68 is rigidly fastened to the platform 2% and is arranged vertically and in proximity to the acetylene tank 23. The tank 68 is preferably smaller in diameter and of less length than the tank 23 and is provided with a raised bottom 69 at the lower portion. The tank 68 is provided with a clean-out opening 70 from which a tube 71 projects which tube is pro-- vided with a controlling valve 72. At an intermediate point the tank 68 is provided with an opening 7 3 from which a filling pipe 74 projects. The upper end of the pipe 74 is provided with a controlling valve 7 5, the casing of which is equipped with a coupling sleeve 76 in which a funnel 77 or other means for facilitating the passage of water is seated. A flanged cover 78 is fitted gastight over the upper end of the tank 68. An externally threaded inlet pipe 79 projects through the cover 78 and its lower end ten minates adjacent the lower end of the tank (38. The pipe 79 at its upper end has a branch '79- coupled to the casing of a safety valve 80% A discharge tube 81 projects from the cover 40 of the tank 23 and a pressure gage S2 is carried by the tube 81. A discharge pipe 83 extends through the cover of the tank (58, said pipe 83 having its lower end arranged above the water level in the tank 68.

The carbid receptacle 452 is provided with a filling opening that is norn'ially sealed by a plug 86. The head of the plug is preferably nut-shaped. In connection with the plug 86 which controls the charging of the receptacle 42, the invention provides means whereby the safety valve 80 is operated if an attempt is made to remove the said plug so that the gas will be conveyed through a pipe 8? to a distance from the plant so that danger of an explosion being caused by gas escaping through the filling opening of the receptacle a2 is avoided. This safety device comprises a band 88 that encircles the receptacle 12 and carries a laterally projecting supporting arm 89, one longitudinal edge of which is provided with a recess 90. A valve operating lever 91 has a pivotal connection 92 with the free end port-ion of the arm 89. A lever 91 has an upwardly-projecting portion 93 from which an arm 94: projects over the top of the receptacle 12 and has its free end provided with a cap 95 that is open at one end. The cap 95 normally incloses the nut-shaped head of the plug 86 so that in order to remove said plug, it will be necessary to rock the lever 91 on its pivotal connection with the arm 89 so that the cap 95 will uncover said plug. free end of the lever 91 has a chain or other flexible connection 96 with the operating lever 97 of the valve 80 The lever 91 carries a laterally-projecting lock housing 98 through which a bolt 99 is slidable. A. spring 100 is coiled about the said bolt and bears against the enlarged portion 101 thereof and the upper portion of the casing with sufficient tension to normally The project the lower portion of the bolt below the base of the housing so that said bolt will engage the recess 90 of the arm 89 to lock therod 91 to said arm. Said bolt 99 is provided with a hand grip 102 by means of which said bolt may be manually removed from the recess 90 to release the lever 91.

By employing the described safety device, it will be seen that before the plug 86 can be removed from the filling opening, the lever 91 must be released from the arm 89 and then swung on its pivotal connection with said arm to remove the cap 95 from said plug, and said lever 91 being connected to the operating lever of the safety valve 80% it will be clear that the swinging movement of said lever will cause said lever to open the said valve so that the gas will pass out of the tank 23 and be conveyed to a distant point by the pipe 87 before the plug 86 can be removed.

Having thus described the invention, what is claimed as new, is

1. An acetylene gas generator including a tank, a gas outlet therefor, a safety valve carried by said outlet, a carbid receptacle carried by said tank and provided with a filling opening, a plug sealing said opening, a supporting arm carried by said tank, an. operating lever pivotally connected to said arm, means for connecting one end of said lever to said safety valve, a cap carried by the other end of said arm and normally inclosing said plug, and means for locking said lever to said arm.

2. An acetylene generator including a tank and carbid receptacle, a safety valve for said tank, said receptacle being provided with a filling opening, a plug for sealing said opening, a supporting arm carried by said tank, a valveoperating lever pivotally connected to said arm, means connecting one end of said lever to said valve, plug inclosing means carried by the other end of said lever. and a locking bolt carried by said lever for engaging said arm.

In testimony whereof I hereunto afliX my signature in presence of two witnesses.
