AGETYLENE-GAS GENERATOR.

Specification of Letters Patent.

Patented Aug. 12,1913.

Application filed July 17, 1912. Serial No. 709,947.

To all whom it may concern:

Be it known that I, JEROME L. RICHARD- soN, a citizen of the United States, residing at Red Oak, in the county of Montgomery and State of Iowa, have invented certain new and useful Improvements in Acetylene- G-as Generators, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to acetylene gas generators and the principal object of the invention is to improve and simplify the general construction of devices of this character.

A second object of the invention is to provide a novel charging means for generators of this description.

With the above and other objects in View, as will be hereinafter apparent, this invention consist-s in general of certain novel constructions, combinations and arrangements of parts, as will behereinafter 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

Fig'ure 1 is a vertical median section through a gas generator constructed in accordance with this invention. Fig. 2 is a section on the line 22, Fig. 1. Fig. 3 is a section on the line 33, Fig. 1.

The generator consists of an outer shell or casing 10 provided with a removable top 11. Secured to the side walls of the outer shell or casing are guide rods 12 whereon slide lugs 13 mounted on the upper and lower ends of a bell 14 adapted to rise and fall Within the casing and sealed by water 15 contained in said casing. This bell 14 has a passage 16 extending centrally therethrough and provided with an offset portion 17. Mounted within the casing 10 is a pipe 18 which lies close to the side of the casing and is secured thereto by suitable clips 19. At the upper end of this pipe there is provided a T 20 and from this leads a pipe 21 to the burners or main, and in this pipe 21 is located a valve 22.

At the lower end of the pipe 18 there is provided an elbow 23 which communicates by means of a pipe 24 with a second elbow 25 from which extends a pipe 26 which leads up within the bell 14 and is in alinement with a pocket 27 extending above the top of said bell.

Leading from the T 20 is a pipe 28 to which is connected a return bend 29 which communicates by means of a pipe 30 with a valve 31. From the valve 31 there leads a pipe 32 which is connected to an elbow 33 which is in turn connected to a pipe 34. The other end of the pipe 34 connects with a T 35 from one end of which leads a pipe 36 which connects with the valve 37.

From the valve 37 a pipe 38 opens into the casing. The stems of the two valves 31 and 37 are connected by a rod 39 from which ex tends a lever 40 provided with a downwardly extending arm 41 adapted to engage the pipe 34 when the parts are in lowered position. The valves 31 and 37 are so arranged that when the lever is in the lowered position as clearly shown in Fig. 1 the valve 31 will be opened and the valve 37 closed.

Within the passage 16 there is provided a cylinder 42 supported bar a cross bar 42 and extending from end to end of this cylinder is a rod 43 having secured to its upper end a T 44. Mounted on this rod 43 is a plurality of graduated carbid containers 45, the upper and lower ones having a series of perforations 46 formed to admit water. These carbid containers are separated one from the other by means of spacers 47 and are supported within the cylinder 42 by a spring 48 which has its lower end resting upon a nut 49 mounted on the threaded end 50 of the rod 43. The openings in the covers through which the spacers pass are of such size that the water may pass into the recep tacles through these openings.

From the T 44 leads a nipple 51 which communicates with an elbow 52 from which leads a pipe 53. Connecting with the pipe 53 is a pipe 54 having an open lower end provided with a collar 55 from which extends a lug 56.- From the T 35 a pipe 38 extends downward close to the side of the casing 10 and at its lower end this pipe is provided with an elbow 57 which communicates by means of a pipe 58 with an elbow 59, and from the elbow 59 there extends a pipe 60 which is so arranged as to telescope within the pipe 54.

Depending from the lever 40 are ears through which extends a rod 56 having at one end a handle 57' and at its other end a depending hook 58.

In the operation of the device the carbid containers 45 are charged with carbid. The lug 56 is engaged with the hook 56 and then the handle 57 is grasped and pulled. This allows the cylinder 42 with the carbid to drop into the water through the opening 16. Thereupon acetylene gas is generated and passes up the cylinder and enters the T ldfrom whence it passes upward through the nipple 51, elbow 52, into the pipe 53 and then passes downward through the pipes 54 and ('30. The gas then passes through the elbows and pipe 58 and upward through the pipe 38, passing finally out through the pipe 21. It will be obvious that the bell acts as a reservoir for any ex cess gas generated over that to be used.

It is to be noted that when lever a0 is raised to a vertical position it closes the valve 31 and opens the valve 37 which is connected with the pipe 38. By this means when it is desired to take the carbid container out for recharging, air is admitted through 38 and down through the valve 37, T 35, pipe 56, and pipes 57, 58, 59 and 60 to the pipe 5 f, thus breaking the seal in the carbid container so that it can be taken out without raising any water with it. It is to be further noted that the reason for making the cans of different sizes is that each is in proportion to its duty. The upper and lower cans are of equal size while the remaining cans are graduated from the top down. The openings for the admission of water in the upper and lower cans are made in the bottom, around the bottom edge and in the flat lid of the bottom can. The admission of water to the intermediate cans is obtained by making the hole at the top through which the spacer passes of relatively large size so that space is left between the supporting member or pipe and this opening. The cans above the bottom are provided with inclined covers for the reason that. there is a constant dripping of water from the roof or top of the container and this permits the same to run off with out starting the generation in any other can from that in which it should be taking place. It will be noted that by reason of the plurality of containers for the acetylene, but one is used at a time.

It will be observed that in the generation of acetylene gas from calcium carbid with this apparatus at the earliest stage of the generation it is desired to quickly charge the bell with the gas. Therefore, a relatively large quantity of carbid is used, the bottom container being larger than that next above. By reason of this, a large surface of carbid in its usual granulated form is exposed to the action of the water with the correspondingly rapid generation of the gas. Now, after the carbid has been used sufliciently to permit a second can to enter the water, the water will still be comparatively free from calcium hydrate in solution, and the small second can will expose enough carbid to the action of the water to render the generation sufliciently rapid to keep the supply up to the quantity used. However, with each successive generation of carbid, the remaining water becomes more and more vitiated by the presence of calcium hydrate, and consequently it is necessary to expose successively larger quantities of carbid to the action of the water in order that the rate of generation may be maintained. On this account the containers are made successively larger from the bot-tom to the top.

There has thus been provided a simple and efficient device of the kind described and for the purpose specified.

It is obvious that many minor changes may be made in the form and construction of this invention without departing from the material principles thereof and it is therefore not wished to confine the invention to the exact form herein shown and described but it is wished to include all such as properly come within the scope claimed.

-Having thus described the invention, what is claimed as new, is 2- 1.
