ACETYLENE-GAS LAMP.

Specification of Letters Yatent.

Application led May 24, 1911. Serial No. 629,203.

To all whom it may concern:

Be it known that I, LORENZO EVANS, a citizen of the United States, residing at Hiteman, in the county of Monroe and State of Iowa, have invented new and useful Improvements in Acetylene-Gas Lamps, of which the following is a specification.

The invention relates to acetylene generators and has for an object to provide an acetylene lamp for producing light.`

Among other features my device embodies a lamp adapted to employ carbid and Water to produce a gas, the lampbeing so arranged that when the carbid container is removed therefrom to refill the container, the lamp will still be operative to produce a light.

In a large number of acetylene lamps now 'in use, when the carbid contained in the main carbid container becomes exhausted, the container must be withdrawn from the lamp and refilled with carbid to produce new gas and in the meantime the light at the burner of the lamp will be extinguished so that if there is no other light present the operator will be in the dark. In my device the lamp is so arranged that a light will be produced at all times, evenwhen the main carbid container is being refilled with carbid to generate a new gas.

Reference is to be had to the accompanying drawings constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which- Figure 1 is a vertical sectional view of my device. Fig. 2 is a horizontal section on the line 2.-2 in Fig. 1, looking in the direction of the arrow. Fig. 3 is a fragmentary' partment 15 being adapted to contain wa-V ter and the compartment 16 being adapted to contain carbid and constitute an auxiliary carbid-container, a cover 17 belng thread- -edly connected to the cover 12 so that carbid can be placed thecompartment 16. A

valve 22 adapted to rest on the 'valve seat 20 and the upper end of the said rod is threaded for. engagement with a head 23 of the tube 18, a knob 24 being secured to the outer end ofthe rod 21. An auxiliary water tube 25, similar to' thetube 18, extends from the cover 12 through the Water compartment 15 and the partition 14 into the auxiliary carbid container 16, the said tube being provided atthe lower end with a valve seat 26 similar to the valve seat 20 and extended through the said tube is a rod 27 having the lower end pointed to form a needle valve' 28 and :the upper end provided with a knob 29 and threadedly engaging the tube 25, the said tube being provided with a series of apertures 30. A

burner 31 extends outwardly from the bodyY 10 and an auxiliary burner 32 extends outwardly from the compartment 16, Vthe burner 31 having an end terminating at the indented portion of the body 10 .to receive gas generated in the container 11.

In the operation of my 'device carbid is placed in the carbid container 11 and in the auxiliary carbid container designated by the numeral land water is poured into the water compartment 15. Now by turning the knob 24, the needle valve 22 will be op-v erated, thus permitting water to flow from the compartment 15 through the apertures 19in the tube 18 and downwardly into the carbid container 11, the mixture of carbidv and water being adapted to produce gas in the usual manner which pours outwardly ythrough the burner 31 where it is ignited.

IV hen the carbid in the container 11 becomes exhausted, the knob 24 is irst operated to actuate the rod 21 and shut off the supply of water to the container 11v and the knob 29 is then actuated to operate the rod 27 thus permitting Water in the compartment 15 to liow into thevauxiliary container or compartment 16 where gas will be produced by the action of the water and the carbid contained in the compartment 16, the said gas being then adapted to pass outfilled a light can be produced at tbe burner v 32 byl permitting vWater from the comparting desirable to retain a use.

iyardly Athrough the burner 82 Where the same is ignited. Thus it will be seen that While the carbid container ll is being re- .ment l5 to flow intothe auxiliary carbid container of my lamp and container has been `properly refilled and connected to the bodyl() the Wat-er supply -to tbe compartment 16 can be shut ont by operating the knob 29 and then by turning the knob-24 Water will again tloW into the carbid container l1, .thus producing new gas in the said container, the said gas being adapted to l'oW outwardly through the burner 31. v

VMy device is particularly adaptable for use in connection with miners lamps, it belight in these kind of lamps at all times when the same are in Having tlius fully described the invention, What`l claim as new, is

1. A lamp comprising a body, a carbid container for removable connection with the said body, a partition formed in the said body to constitute a Water compartment and an auxiliary carbid container, burners connected With the said carbid container and said auxiliary carbid container, means tor after the carbidl :imacat supplying Water to the said carbid container and means for supplying water to the said auxiliary carbid container. c 2. A lamp comprising a body, a carbid .container for removable connection With formed in thev said body to constitute a Water compartment and an auxiliary carbid container and lapertiired tubes the said body, a partition extending from the said Water compartment to the said carbid container and said `auxiliary carbid container for supplying Water thereto.

3. A lainp comprising a body, a 'carbid container for removable connection with Vtlie said body, a partition formed in the said body to constitute a Water compartment and an auxiliary carbid container, means for supplying Water to the said carbid container, ineansl for supplying Water to the said auxiliary carbid container, an adjusting screw for controlling the supply of water to the said carbid' container and a second screw for controlling the supply off Water to the said auxiliary carbid container. In testimony whereof I aflix my 'signature Iin presence of tWo Witnesses. l
