SPECIFICATION forming art of Letters Patent No. 646,404, dated March 27, "1900. Application filed October 31,1899. Serial No. 735,350, (No model.)

producing acetylene gas, especially constructed for the purpose of using candles, molded sticks', or the like made of calcium carbid. ThlS-ilIlPlOVBd apparatus can be recharged while working and without occasioning any escape of gas. I will now describe it with reference to the accompanying drawings, in

Figural isavertical. section. Fig. 2 is a View, half plan and half horizontal section, on line 2 2, Fig.1. Figs. 3, 4, and5 represent in vertical section the various parts of a can bid box or chamber; and Fig. 6 is a sectional view on the line 6 6, Fig. 5.

. My apparatus consists of .a tank or vessel a,

in which are placed the regulating-bell b and the various carbid chambers or containers 0.0.

The respective positions of these various parts of the apparatus can be varied. Usually the 'bellis placed at the center and the carbid- 3 chambers around the latter. Each of the carbid-chambers consists of .an oblong or tubular bell c, in which can be engaged by its lower opening a tube (I, intended to receive the carbid stick or candle f, this latter being supported by a grid r. As seen more clearly in Fig. 5, the'tubc d is open at both ends and toward its lower extremity has two opposite slots or notchesc-ut into it, leaving side walls covered by a small bell g, which is free and merely rests upon the lower collar'h of the tube d; bell c by means of any suitable device-for inst'ance,by a bayonet-joint or by the hook-f catchesi. (Shown'on'the drawi'ngsz) In its upperp'ortion' the bell c is divided by a grid This tube d can be secured-tothe or grating 7c, and above the said grid itcon mu nicates with a vertical tube j, which is carried by the bell, this tube beingclosed at the top and open'at the bottom. As indicated in Fig. 3, the space above the grid 7; may concan be supported. in the vessel a by means of a flange or shoulder I resting upon the cover a at the upper partotthe vessel, the said cover being provided with openings to receive the various carbid-chainbers c 0. These latter can thus be easily inserted and withdrawn.

The bottom of the tank a is preferably formed by a partition m-,which is iu'clined'or funnels .tain' a suitable gasepurifying material. Each oi the bells c, with all its working parts,-'aswell as the tube j fixed thereto, as explained,

shaped, and has at its lowest part a valved outlet m th ough which the residuum. may berernoved. Beneath the-partition m isa closed chamber m, toward the lower part of which thevertical tubes n n deliver the gas.

from the chambers c. This chamber m is supplied with water to a point above the discharge-points of the tubes, so as to constitute a water seal andwashing-chamber. These tubes n are of a sufficient height when the chambers c are in place to enter the tubes up to the upperportion. The dilterent chain.- bers c are constructed in this manner, and

'with the tube jof eachof them corresponds pended. from the top of the bell by a central tube 1; and constitutes a displacement-body. The weight of this receiver 1) can be regulated as desired by introducing Water, granulated lead, &c., into the. same through a pipe 'q; 7

. whose otherend'projects through the crown of the bell. 1 Into the upper part of this gov-' ernor-bell b there delivers a tube '2", which too opens from theupper part of the chambertn, Y

above the level of the water therein. In the present instance this gas -tube ropens'into the central tube 19, which carries the receiver I 1 the chamber being in the. positioushownon p, and-has suitable ontlets'f or the gas into I cook it for the escape of air. 4

The working of the apparatusis as follows:

Each o'fithe chambers cis furnished 'th the} gas-generatin g substance in the form stick,

cartridge, or candle f, the various parts of the drawings and as above stated. These chambers cc are placed, in thavessel a, this latter being filled with water up to a certain.

height. The level oii this water; tends to equalize itself in the vessel-ct, inthe bellrb, andin,thecarbid-chamberscc. Consequently when the water comes in contact with the candles f gas is given of. If the loose bellcov ers g are used over the tubesd, the first effects'of. the generation of the gas will be to depress the water-level in the'co vers or to raise these covers g until the gas can escape around their lower edges and up into the bells c. The gas rising in the bells c. escapes by the tubes j and it (after havingpassedfiif necessary, in contact with the desiccating-material placed above the grids k) and is delifts with it the mass 19, which, being of a chambers c c.

' ceases, and the pressure diminishing by the 1 redesoends'.

livered into the midst ofthewater contained in the chamber m, through which water it bubbles. It collects in the upper portion of this chamber m and passes ;t rough tube 5', whence it reaches the governor-belib, which it fills and raises. This bell being so raised fairly-considerable volume and partly standing out of the water, consequently displaces a much less quantity of water. that the level of water in the hell I) is lowered aswell as in the vesselfa and in the carbid- The carbid sticks no longer dipping into the water, the production of gas consumption of the" gas the governor-bell b The receiver 10 is thereupon immersed to a greater extent, displacing a greater quantity of water and causing a rise in level'in the chambers c, the candles again dipping into the water and the production of gas again commencing. This succession of phenomena will be effected in a continuous manner, and the production of gas thus takes place regularly, according to consumption.

It will be remarked that in case of an ex cessive production of gasthe difl'erent chain bers or bells'c are raised a certain height, for they are held freely in the openings inthe cover a, and thus increase the capacity of the apparatus occupied by the gas. Also in each of the. chambers c the bell gin'tervenes as a safety device, for in case of an excessive production the water is at first driven back from within the hell 9 to its outside-that is quent in the chamber cthe candle fconsey no longer dipping into the water. It will be observed that with this apparatosay i It follows ms the recharging of the generato'nwith the gasproducing substance can be effected without any escape of gas. By raising up any one chamber 0 for this purpose the gas-tube j is disengaged from the tube n, and thislatter is then in communication with the atmosphere; but the gas contained inthe chamber m' drives back' the water' in this tube t a 7 height corresponding with the pressure. I"may obviously modify the construction of this apparatus without departing from the spirit of my invention.
