Specification of Letters Patent.

Patented May 7, 1912.

Application led April 27, 1911. Serial No. 623,641.

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- Generators, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to apparatus for generating acetylene gas, and has special reference to that type of acetylene gas generator 1n which a vertically movable bell is employed together with means for gradually submerging carbid into water to generate and collectthe gas within said bell.

The invention has for its object to provide an improved acetylene gas generator which will be simple in construction and effective in operat-ion and may be readily removed for repair and charged with carbid and which will avoid any danger of explosion.

Referring to the accompanying drawings: Figure 1 is a View in vertical section of an acetylene gas generator constructed in accordance with this invention and shown as sunk in the ground. Fig. 2 is an elongated detail view in vertical section of a portion of the apparatus consisting of a carbid holder which is removably mounted in the gas bell. in vertical section of a portion of the carbid holder. Fig. 4 is a detail plan view of one of a number of disks employed with a carbid holder. Fig. 5 is an enlarged detail view of a metallic blank used to form the angular perforated metallic strip shown in Fig. 6. Fig. 6 is a detail view of an angular perforated metallic strip serving as a water conduit for the carbid holder. Fig. 7 is an enlarged detail view of a portion of the end of a gas pipe located in the end of a gas pipe shown in vertical section.

In the construction of this invention a metallic tank 1 of suitable size is employed which is sunk in the ground as shown in Fig. 1, and is `provided with a solid bottom 2. Located in the tank 1 is a vertically movable bell 3 having at its upper end laterally projecting arms' 4, each of said arms having on its outer end a friction roller 5 which bears against the inside of the tank 1, the arms 4 and friction rollers 5 serving to steady the bell 3 when it is raised and lowered. Suspended within the bell 3 is a cylindrical metallic casing 6 open -at its Fig. 3 is an enlarged detail view i lower end and having a closed top 7 with an annular flange 8 which is adapted to be seated inthe shoulder of an opening in the top of the bell 3, through which opening the casing 6 is adapted to be removed. The' casing 6 is yof a length equal to that of the bell 3 and is for the purpose of containing carbid. The casing 6 is secured in place by any suitable means, as, for example, by nuts and bolts 9. Extending centrally through the casing 6 and projecting through its top 7 is a` pipe 10 which is held in place by means of a transverse bar 11 through which the pipe 10 projects, and is clamped in place thereon by nuts 12. The bent outer ends 13 of the bar 11 rest on the top of the bell 3.

Located at intervals apart on the pipe 10 1 and removable therefrom are perforated '3 disks 14 which are slidably removable from 1 the pipe 10 and are held in spaced relation ,j to each other by any suitable means, as, for i example, by short tubes 15 mounted on the tube 10 and having a flanged lower end 16 chambered portion 16 having a lower l open end and located in said chamber 16 and slidably and detachably mounted on the pipe 10 is a cone shaped float 17. It aids in lifting the carbid holder and bell.

Mounted in the sides of the casing 6 are a lnumber of vertical perforated conduits 18 tofv any suitable shape for the passage of f water, and, as'here shown, preferably of an angular shape formed by bending a metallic blankstrip 19, as shown in Fig. 5 int-o the angular shapel shown in Fig. 6 with'the sides 20 having apertures 21. These perforated conduits 18 are secured in any suitable manner to the inner sides of the casing 6 and the disks 14 are seated over said conduits 18 by means of notches 22 in the periphery of each disk. These perforated conduits 18 are for the purpose of conducting l wat-er to the carbid and also for the passage of the generated gas to the tube 10 which is provided at its upper end with a number of and the lower end of the pipe 24 is connected by an elbow joint 26 with a pipe coupling joint 27 containing a cock or valve. The

. other elbow pipe 2S of the coupling joint has the bell 3 is admitted to the desired point for use by means of a vertical pipe 33 having its 'open upper end projecting into the bell and its lower end coupled to a horizontal short pipe 34 which in turn is coupled to a vertical l pipe 35 projecting out of the top of the casing 1 and connected by a short pipe 36 with a pipe coupling 37 containing a stop cock 38, said coupling being connected to a pipe 39 leading to a place where the gas is to be use Located at the bottom of the casing 6 and passing through its wall is a U-shaped tube 40 extending up on each side of the wall of the casing and secured thereto in any suitable manner. The tube 40 serves to prevent the escape of gas while the apparatus is being charged, being of a suflicient length to be submerged in the water and thus making a water seal just before the carbid touches the water and begins to generate gas, and, ashereinafter more fully set forth, also serves to permit the escape of all the air through the lower end of the casing 6 while the carbid holder is being replaced after bej ing recharged, the gas bell lying flat on the water thus forcing all of the air out before the upper end of the tube 40 is submerged so as to fill with water.

The carbid casing 6 is charged with carbid by removing it from the bell and inverting the same. The oat 17 and the disks 14 with their supporting tubes 15 are re moved from the pipe 10 and each chamber formed by the disks 14 as they are replaced is filled with carbid 41. After the carbid holder has been charged, as aforesaid, it is replaced in the bell and the latter is lowered into the water 42 in the tank l. In charging the water the gas bell 3 lies flat on the water, and the pipes 29 and 83 telescope into pipes 43 depending from the top of the bell, thereby leaving the bell or carbid holder entirely free from air. As soon as the carbid casing charged with carbid strikes the water the pressure is created in the carbid holder and as it is forced down to the proper position the air is expelled through the tube 40 and just before the carbid at the lower end of the carbid holder comes in contact with the water and begins to make gas, the tube 40 fills the water, making a gas tight seal, as shown in Fig. 3, and starts the machine in operation and practically no air can be drawn out of the pipes or mixed with the gas. By placing the carbid on a series of perforated shelves the whole charge of carbid is prevented from being moistened at once, and the necessity for feeding the carbid to the water is avoided, and,V moreover, the caking of the residuum or refuse carbid is avoided and the `spaces between the several charges of carbid assist in preventing an over supply of gas and make it unnecessary to change the water so frequently for the reason that all of the residuum of the carbid is retained in the holder, from which it is readily removed before recharging.

By means of the foregoing construction the machine may readily be recharged while in operation, the service being continuous without a sufiicient amount of air being mixed with the gas to materially aiect the brilliancy of the light. By means of this -construction also Yin cutting off the gas described 1n connection with the handle 32 the carbid holder can be removed for recharging the machine without turning out the lights. It will readily be seen that as the carbid holder is lowered into the water the latter will pass through the perforated conduits 18 and is distributed among thc carbid gradually as the carbid holder is lowered the generated gas passing down through the tube 10 and out of the tube 29 into the bell.

What I claim is 1. In an acetylene gas generator of the kind described, a carbid holder consisting of a cylindrical casing with a closed top and an open lower end, and a chamber in the lower end of said casing, a central gas tube extending through said casing, and having an open lower end, and an apertured upper end communicating with said casing, a column of perforated disks detachably mounted on said tube and spaced apart from each other, and a U-shaped tube mounted in the side of the lower end of said carbid holder with its upper end in a plane below the lower end of the column of perforated disks, and serving to form a water seal therefor.

2. In an acetylene gas generator of the kind described, a water tank, a bell vertically movable in said water tank, a carbid holder consisting of a cylindrical casing suspended from the top of said bell, and having a central gas tube, a number of removable perforated disks mounted thereon and spaced apart from each other, a number of vertical conduits having perforations and located on the inner side of said holder and i with said valve and projecting through the top of said bell.

3. In an acetylene gas generator of the kind described, a water tank, a bell vertically movable in said water tank, and having tubes depending from its top inside thereof, and an opening in its top, a carbid holder depending within said bell and detachably mounted in said opening in itsv top, and having a central gas tube extending from top to bottom of said holder and open at its lower end and having apertures at its upper end opening into said holder, a number of perforated disks slidably and detachably mounted on said pipe, and spaced apart from each other, tubes on said pipe located between said disks, angular perforated conduits located on the inner sides of said holder, the lower end of said holder being formed with a chamber, a cone shaped supe port detachably mounted on said pipe in said chamber, a U-shaped pipe mounted on one sideL of said chamber and serving as a water seal, a U-shaped pipe located in the lower end of said water tank and having one arm projecting into said pipe in the carbid holder and its other arm opening into the bell, a discharge pipe projecting into the lower end of said bell, a vertical pipe connected with said discharge pipe and projecting through the top of the water tank, and a pipe leading to the point of discharge connected with said vertical pipe, the vertical pipes projecting into the bell being adapted to telescope with the pipes depending from the top of the bell.

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