To aZZ 1071,0721, zit may concern.-

Be it known that LXVILLIAM H. BAZLEY, of Whitman, in the county of Plymouth and State of Massachusetts, have invented an 1111- before the first carbid-holde'r of the regular series comes in contact with the water; also, to provide the carbid-holders with sloping top walls, which protect the carbid from intimate association with the moisture contained in the gas and also direct the passage of the gas; also, to provide the carbid-holders with an outlet for the gas in open communication with a passage by which the gas is delivered to the top of the gas-chamber within the bell, and also to provide a chamber within the bell which is at all times in open communication with the atmosphere, which provides an outlet for the air contained within the bell when the apparatus is first charged and also an escape for the gas in caseof overproduction Figure 1 shows in vertical section an acetylens-gas generator embodying this invention; Fig. 2 is a verticalsection and partial elevation of the bell, showing the carbid-holders and support therefor; and Fig. 3 is a horizontal section of the bell shown in Fig. 1, taken,

on the dotted line 3 3.

a represents the stationary tank, of cylindrical form,whicl1 is designed to be filled with water, and b is the bell, which is made of less diameter than the'tank a and adapted to work up and down therein. The tank a has a main compartment ct and an auxiliary compartment a said compartments being formed by a division-wall a secured in place within the tank near the bottom. Centrally disposed within the tank a is a vertical pipe 0, which extends from the bottom to a point above the top of the tank, passing through both compartments thereof, and a pipe 0' leads from said vertical pipe 0 at a point within the com vtight telescopic joint.

partment a out through the side wall of the tank, which is connected to a servicepipe 0 located outside of the tank. A pipe at is cen trally disposed within the bell, whichis made larger in diameter than the pipe 0, so as to work up and down over said pipe 0 telescopically. The pipe (Z is made long enough to project down to a-point substantially flush with the lower end of the bell, and as said pipe 0 projects above the tank it will be seen that the pipe d always incloses the upper end portion, at least, of the pipe 0. The telescopic connection ofthe pipes c and (Z is at all times beneath the surface of the water contained in the tank a, so that a water seal is provided for the pipes at this point, insuring a gas- The upper end of the pipe-d is connected by a short pipe at to the upper end of the bell, said short pipe (1 projecting downward from the crown thereof, so that the pipe d is really connected to the crown of the bell, and therefore moves up and down with said bell. The telescopically-connected pipes c and (Z serve to conduct the gas from the bell to the service-pipe.

e represents a diaphragmor plate horizontally disposed within the bell, which forms the top wall of the gas-chamber, and pipes e are connected to said top wall, which pass upward for a short distance and are connected by pipes c to the pipe (1, so that an open connection is established between the gas-chamber and the telescopic conducting-pipes c d. lIerein I have shown two of these short pipes 6'; but one or any other number maybe provided.

f represents a cylinder which is centrally disposed within'the bell Z) concentric to the pipe cl, and said cylinder is made open atits lower end and closed by a plate f at its upper end, and said cylinderis made long enough to extend to a point near the lower end of the bell and up through the top wall e of the gaschamberandinto the chamber at the top of the bell above said gaschamber. This cylinder serves as an air-chamber,and it is designed and intended that it shall be at all times in open communication with the atmosphere, and to accomplish this result a vertical pipe f is contained in the tank a, which is located beside the pipe 0 and which extends from at or near the bottom of the tank a up into the cylinder or air-chamber f. The pipe f pro-- jects a short distance above the top of the distance above the surface of the water contained in the tank a. The lower end of the cylinder f is immersed in the water in the tank a, so that a water seal is provided between the cylinder or air-chamber f and the pipe f. The lower end of the pipe f projects down into the lower compartment a of the tank a and is provided at a point a short distance'below the division-wall a with an outlet f to the atmosphere. Thus the cylinder or air-chamber f is in open communication with the atmosphere at all times by means of the pipef In case of overproduction of the gas within the bell the bell will be lifted to its most elevated position, and when in such position a hole 20 in the wall of the chamber fwill be brought to a point above the water-level, and thereby an open com munication established with the atmosphere through the chamberf and pipe f The carbid-holders, a number of which will be provided, are arranged on a support which is herein shown as comprising two cylinders h h, arranged centrally one within the other with an annular space between them, and

' said tubular support is mounted upon and is tion of the bell.

free to slide up and down on the cylinder f, which serves as a guide therefor. The tubular support 77. 71 has at its lower end a float h of anysuitableconstruction, which rests on the water contained in the tank a, or it may be immersed therein, according to the posi- The upper end of the tubular support bears against the top wall 0 of the gas-chamber, so that as the bell descends said tubular support and parts attached to or connected with it will correspondingly descend. The carbid-holders each consist of a box-like structure 2, open at one end for the introduction of the carbid and having a sloping top wall Each carbid-holder also has an opening at its inner end communicating with the annular space between the cylinders h h'as, for instance, the cylinder hmay form the inner wall of each carbid-holder, and said cylinder at such points may be cut open or punctured, as at to provide such an opening'. The gas formed in the carbid-holders thus passes therefrom into the annular space between the cylinders h 72-. At the upper ends of the cylinders the annular space is left open, and consequently the gas which enters said space is free to pass up and out at the top of the tubular support, thereby entering the gas-chamber of the bell at the top, which is an important feature. The gas formed in the carbid-holders is well laden with moisture, and by causing it to enter the gas-chamber. at the top the moisture is al- By making the top ably, as shown, the moisture falling thereon has an opportunity to run off, and as-a result thecarbid contained in each .carbid-holder is not brought into so intimate association with the moisture as, would otherwise be the case.

Furthermore, said sloping -walls direct the passage of the gas to the openings The lowermost carbid-holder of the regular series is located at a point just above the connection of a trap-pipe f, to be described, with the gas-chamber, so that before said lowermost carbid-holder is immersed in the water said pipe f" will be trapped or water-sealed.

The air-chamberf contains within it a trappipe f comprising a vertical portion extending from nearly end to end of the chamber in parallelism with the central pipe 01 and a U- shaped portion at its lower end. The trappipe f is open at both ends and is connected at its lower end only to the wall of the chamber f at a point a short distance above the lower end of said chamber, such point, however, being sufficiently above the lower end of the chamber so as to be above the surface of the water contained in the tank a when the bell is in its elevated position, so that when first starting the apparatus the air contained in the bell or in the gas-chamber thereof can be driven out through said trap-pipe. Open communication is thus established between the gas-chamber of the bell and the atmosphere until such time as the bell descends, so as to allow the water to enter the trap-pipe,

when the U-shaped portion thereof immediately fills, and thereby Water-seals the pipe and closes the communication with the atmosphere previously established.

When first starting the apparatus, the gaschamber within the bell is filled with air, and it is desirable to displace the air with gas with as little loss of gas as possible and without causing atemporary overproduction, and to accomplish this result a supplemental carbid-holder is provided, as m, which is attached to the tubular support It 72. in the same manner as the other carbid-holders, so that the gas generated therein will be delivered to the gaschamber at the top; but said carbid-holder m is located at a point below the lowermost carbid-holder of the regular series and also below the connection of the trappipe, f with the gas-chamber, which, it will. be understood,is an outlet from the gas-chamber to the atmosphere. tal carbid-holder m a small quantity of carbid is placed, which will be sufficient to gen erateenoughgastofillthegas-chamber. This supplemental carbid-holder mt is first immersed in the water, and as the gas is generated it rises and enters the gas-chamber at the top and drives the air out through the trap-pipef This action continues until the gas-chamber becomes filled with gas, and then the bell gradually descends and the outlet to the pipe f enters the Water and said pipe becomes water-sealed, and the gas-chamber is then closed to the atmosphere. This occurs previous to the first carbid-holder of the regular series entering the water. I

It will be understood that but a small quantity of carbid is required for the production of sufficient gas to displace the air in the bell,

Into this supplemen and consequently the supplemental holder will be supplied with but a small quantity, while the other carbid-holders will be supplied with as much as desired. I believe myself to be the first to employ a supplemental carbid-holder for the accomplishment of this result, and therefore do not desire to limit my invention to the particular construction of the carbid-bolder when used for this purpose or to the construction of the other parts of the apparatus, so long as said supplemental carbid-holder is located below the outlet from the gas-chamber to the atmosphere.
