GAS-GENERATOR.

Specification of Letters Patent.

Patented Jan. 11, 1921.

Application filed November 21, 1919. Serial No. 339,598.

To all whom it may concern:

Be it known that we, FRED TURNER and new and useful Improvements in Gas-Generators, of which the following is a specifi cation. I

This invention relates to acetylene-gas generators, and embodies among other features an auxiliary carbid container. adapted for use when it is necessary to refill the main carbid container, thus maintaining the device in operation while performing this duty.

To this end, use is made of an adjustable cover for the water container, the cover supporting an auxiliary carbid container in a position to be submersed when the cover is tight upon said container, the cover being provided with a gas escape opening at WlllCh point the gas is ignited while the main. carbid container is being refilled. I

Other objects and advantages will appear when the following detail description is taken in connection with the accompanying drawings the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawing forming part of this specification like numerals of reference, indicate similar parts in the several views and wherein Figure 1 is a vertical sectional view through the device forming the subject matter of our invention.

Fig. 2 is a similar view showing the carbid arranged within the carbid container.

Fig. 3 is a sectional view taken on line 33 of Fig. 1.

Fig. 4 is a sectional view taken on line 4-4 of Fig. 1.

The device forming the subject matter of our invention comprises a water container 10 and a main carbid container 11, the latter being separated from the water container by means of a partition 12. The partition 12 has a small opening 13'from which depends a tube 14, the latter conveying water from the container to the carbid container 11. A similar tube 15 is supported by the water container and a valve rod 16 is passed through said tube to control the amount of water admitted to the carbid container 11. Projectin from the carbid container is a burner tube 17, which is threaded to accommodate a cap 18. The cap is provided with a central opening 19 for the escape of gas,

an'dxat which point the gas'isignited. A partition 20 is arranged in the tube 17 to prevent thefiltering element 21 from gaining access to the carbid container, the partitlon 20 being perforated as shown to allow for the passage of gas through the openmg 19.- The filtering element or medium 21 may be of any suitable material as it is provlded to prevent the dust from the carbid or other foreign matter from clogging the opening 19 of the cap. The water container 10 is closed at its upper end by means of a cap 22, while the carbid container is closed at the bottom by means of a cap 23, gaskets 241 being arranged within each cap as shown.

With a view of maintaining the device in operation, when it is necessary to refill the carbid container 11, we make use of an auxiliary carbid container 25. This container is in the form of a tube depending from the cap 22. The tube 25 is open at the bottom and supports the stopper 26 the latter having a vertical bore .to receive a tube 27 A valve including a stem 28 is fitted within the tube 27. The cap 22 is provided with an opening 29 which allows the escape of the generated gas from the container 25, and at which point the gas is ignited. The cap 22 is further provided with a vent 30 to admit air to the water chamber. In practice, when it is desired to refill the main carbid container 11, and at the same time maintain the device in operation, the cap 22, which is threadedly associated with the container 10 is removed, and the stopper 26 separated from the container 25. A quantity of carbid is then placed in the container 25, and the cap 22 again placed in position. Consequently a quantity of gas is generated in the container 25, which gas escapes through the opening 29 at which point it is ignited. The flame is of course extinguished at the point 19 while the container 11 is being refilled with carbid.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily understood, we desire to have it understood that we do not limit ourselves to the details of construction, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

Having thus described our invention what we claim as new is 1. An acetylene gas generator comprising a water container, a carbid container, means for controlling the admittance of water from the water container to the carbid container, said carbid container having a gas outlet opening, a cap for said water container, an auxiliary carbid container carried by the cap and depending therefrom so that the carbid contained therein may be submersed, said auxiliary carbid container being open at its lower end, a stopper positioned within said lower end, said cap having an outlet opening for the auxiliary carbid container, and a valve arranged in said stopper between the water container and said auxiliary carbid container.

2. An acetylene gas generator comprising a water container, a carbid container, means for controlling the admittance of water from the water container to the carbid container, said carbid container having a gas outlet opening, a cap for said water container, an auxiliary carbid container carried by the cap and depending therefrom and adapted to be partly submersed, said cap having an outlet opening for the auxiliary carbid container, a stopper fitted within the auxiliary container and the auxiliary carbid container, and a valve including a stem arranged within said valve.

In testimony whereof We affix our signatures.

FRED TURNER. THOMAS BURTON.
