Improvements in Acetylene-Gas Machines, of

which the following is a specification.

My invention relates to means to control the feed of carbid in such machines and to other features thereof hereinafterdescribed; and the object thereof is to provide a simple and efiicient machine. I accomplish this object by the mechanism described herein and illustrated in the accompanying drawings, in which Figure 1 is'a cross-section taken on line 1 1 of the generator andgas-holder. Fig. 3 is a side elevation, partly'in section, with parts broken away. Fig. 4 is a central vertical section of the carbid-chamber and its outletchamber with the carbid-controlling valves in'elevation. Fig. 5 is a detail of the top of the valve-operating rod. 2

In the drawings, 6 is the carbid-chamber, which is provided with a port 7.in the .bottom thereof, which opens into chamberS, which I will call a safety-chamber. This safetychamber is provided with a port 9 in the bottom thereof, which opens into a hood 10, that opens into the generator-chamber 11, projecting downwardly thereinto. On thelower end of the casing of the safety-chamber is a moisfrom running down the outside wall of the safety-chamber to the outlet thereof. The topof the carbid-chamber is provided with a screw-cap 13, which is removed when it is desired to refill the chamber.

ports a cap 15 secured thereto, which cap A brace 14 sup- .covers the upper end of the carbid-valve-oper- :ating rod 16, upon which is slidably mounted a sleeve 17, which carries near its lower end conical.-shaped valves" 18 and 1.9, which control port 7 of thecarbid-chamber and port 9 ;of the safety-chamber. v the carbid as it falls from the safety-chamber Valve 19 willdeflect -so it will fall into the water at a point outside of the vertical line projected from the moisture-collar 12, thereby causing the principal part of the steam to arise outside of the collar. Below valve 19 is asupporting-cone 20,

. .which is rigidly secured to the valve-operating rod 16. This valve-operating rod carries on the top thereof, within cap 15, a nut 21, be-, tween which and brace 14 is spring 22, which is adapted normally to hold valve 18 so that it closes port 7 and valve 19 to close port 9. This rod is U-shaped, as best shown in Fig. 2, and passes upwardly and. out of the generating-chamber through the guide-tube 23, which is secured in partition 24, which partition forms the top of the generating-chamber.

A sealing-tube 25 is secured to rod 16 and istelescopically movable upon tube 23 to prevent any gas escaping upwardly through said tube. The exterior end of rod 16 terminates in a yoke16, and between this yoke and'cover 26 is spiral spring 27, which also normally .holds valves 18 and 19 to close ports 7 and 9, respectively. Mounted on the top of gas-bell 28 is a standard 29, which carries an arm 29,

which passes through yoke 16' and is adapted tocontact therewith and depress the valveoperating rod so as to open valves 18 and 19 when the gas in saidbell is nearly exhausted. Should an excess of carbid fall into the generator-chamber by reason of the failure of valves 18 and '19 shutting ofit' the supply of carbid, the accumulation of gas in the bell will cause it to rise until arm 29 contacts with the top of the yoke and will raise said rod to a height sufficient to seat valves 18 I and 19 or willprevent the further rise of the gas-bell, at which time ports 30 in sealing -tube 31 will be so close to the waterline 32 in the gas-bell that the gas will pass through said ports 33 in sealing-tube 34, which is telescopically movable upon pipe 35, which pipe opens into the condensing-chamber 36 and serves as an escape-pipe for the gas which passes therethrough and into the condensingchamber and from thence through pipe 37 and.

through outlet 38, (shown in Fig. 1,) which outlet may be connected by pipe to lead the gas outside the building if the gas-machine is kept within an inclosed building. The generator-chamber is provided with a fillingspout 39, and the water necessary to fill the machine passes therefrom through port 40 and thence through tube 41, having a number of small ports 42 in the vertical wall thereof and near its bottom, as shown in Fig.2. This tube I will call a filling-tube, and passing therethrough is rod 43,. having handle 44 on the top thereof and stirrer-blade 45 on the I bottom thereof, which stirrer is operated to cause the ash to flow out through pipe 46 when the machine is being cleaned. Leading from the generator-chamber is the supply- 5 pipe 47, which terminates in the gas-bell. On the pipe 47 is a three-way valve 48, which valve is also connected to pipe 37 This valve 51 leads the gas therefrom to the place of use.

' The safety-chamber is removably secured to the top of chamber by bolts 54. Hood 1O 1 is provided with a plurality of holes 55,through which the gas that rises in the hood is forced in detached streams, thereby washing the gas better than if it were not separated into jets.

Arm 29 is slidable through its support 29, which support is secured to the gas-bell, so that when it is desired to refill the machine said arm can be removed away from engagement with yoke 16, thereby permitting springs 22 and 27 to bring valves 18 and 19 to close ports 7 and 9, respectively, when the chambercan be refilled.

It will be observed that in case the user neglects to disconnect arm 29 from yoke 16 Valve 19 will be in the position shown in Fig. 4:, which closes port 9, and that the safetychamber will fill with carbid and that the valve will not rise so as to open port 9, and the carbid will then have to be removed from the machine and valve 18 permitted to close port 7 before the carbid-chamber is in a proper position to receive a new supply, thus putting an effective check upon the improper filling of the machine, as no carbid can possibly get into the water in the generator until the valves are in their proper position. As soon as the carbid-chamber is refilled and cap 13 replaced the carbid-operating rod is depressed by hand until the gas-bell rises to a point where arm 29 can be slid back with the end thereof projecting through yoke 16. It will also be observed that as ports 42 are in the vertical wall of the filling-tube and that the tube is in close engagement at the bottom with the stirreroperating rod no gas will escape therethrough and that said tube performs the functions of a seal around this stirrer-rod and a fillingtube. The condensing-chamber 36 is provided with a filling-spout 52 for filling said chamber with the necessary water, which passes through port 53 into said chamber.
