ACETYLENE-LAMP.

Application filed December 4, 1917.

To all whom it may concern Be it known that I, HARRY GALL, a citizen of the United States, residing at Ishpeming, in the county of Marquette and State of Michigan, have invented certain new and useful Improvements in Acetylene- Lamps, of which the following is a specification.

This invention relates to acetylene generators, and more particularl to acetylene lamps for use by miners and others.

The object of the invention is to construct a lamp of this character with two independ ent gas generating chambers adaptedto supply acetylene gas to burners so that when the carbid in one chamber becomes exhausted the other may be brought into operation to continuously supply light, the empty chamber being filled after the;- other is in operation so that one may be always ready for use on the exhaustion of the other.

Another object is to provide improved means for holding the water supply valves in open position, said holding meansbeing quickly brought into use when desired.

With the foregoing and other objects 111 view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a front elevation partly in section of a lamp constructed in zu'cordance with this invention, and

Fig. 2 represents a, transverse vertical section thereof.

In the embodiment illustrated a cylindrical receptacle 1 is shown provided at its opposite ends with closures 2 in the form of screw caps having gaskets; 3 arranged between said caps and the receptacle to pro vide a. fluid tight connection between them,

the receptacle being shown reduced at its ends with shoulders 4: formed at the inner ends or bases of said reduced ends and against which the packing or gasket is clamped. This cylindrical receptacle 1 has a partition 5 arranged transversely thereof preferably midway its ends so as to divide the receptacle into two chambers which are designed to contain carbid for the genera- Speciflcation of Letters Patent.

tion of the gas for supplying light to the lamp. These chambers 6 and 7 have valved openings communicating with a water container 8 which is also here shown cylindrical in form although obviously. it may be of any other desired configuration. This water container or tank is provided with a filling opening 9 in its upper wall equipped with a suitable closure 10 and which is designed to contain the water to be supplied to the chambers 6 and 7 for generating the acetylene gas.

Surrounding each of the openings in the chambers 6- and '7 a depending tube as 11 through which extends a rod 12 which is movable longitudinally in the tube 11, the upper portion of said rod extending transversely through the water tank 8 and surrounded by a sleeve 13 which terminates at its outer end in a head 14. Coiled around the sleeve 13 within the tank 8 is a spring 15 which bears at one end against the inner face of the tank and at its other end against the stop 16' carried by the rod 12. This spring exerts its tension to normally force the rod downwardly through the tube 11 and cut off the water supply which is accomplished by the engagement of a packing or vtlve 17 carried by the rod 12.

A ferrule or sleeve 18 preferably surrounds the opening in tank 8 through which the sleeve 13 passes as is shown clearly in Fig. 1 and which operates as a guide therefor.

A plate 19 is hinged at one end to the tank 8 adjacent the ferrule 18 and is designed to be elevated and engaged with the under face of the head 14 carried by the rod 12 for holding this rod in raised position to open the valve between. tank 8- and the carbid chamber 7.

While one of these chambers and the water controlling valve therefor only is described, it is to be understood that the other chamber is constructed exactly like it.

A gas tube or chamber 20 is arranged in front of the water tank 8 and slightly above the receptacle 1, being supported on said re-' ceptacle by tubular standards 21 which also operate to afford communication between the chambers 6 and 7 and the gas chamber 20 to permit the gas nerated in the chambers 6 and 7 to pass into the supply chamber 20 from which it passes to the burners as 22 which project laterally from the chamber 20 and open into a reflector 23 which is bolted to the gas tube or chamber 20 by a bolt 24 which extends centrally througih said reflector, the burners also operating to assist in holding the reflector in position.

The gas chamber 20 is also connected with the front of the water tank 8 as shown at 25, said connection being effected by soldering or in any other suitable manner.

A hook 26 is carried by the rear wall of the water tank 8 and is designed for supporting the lamp, it being ordinarily engaged with. the cap of a miner or other person using it, but obviously it may be engaged with any other suitable support, it being not restricted in use to miners caps.

In the use of this lamp the chambers 6 and 7 having been filled with carbid through the ends which are closed by the caps 2 and said caps placed in operative connection therewith, the tank 8 is filled with water through the opening 9 and the lamp is then ready for use. In order that gas may be generated the rod 12 is raised by lifting the head 14 at its outer end and then swinging upwardly the holder 19 into the position shown at the right of Fig. 1. When this holder is so positioned the valve 17 will be lifted from the opening which communicates with the chamber 7 and water from tank 8 will be allowed to flow through the tube 11 downward into the chamber and onto the carbid whereby acetylene gas will be generated within this chamber and will pass out through one of the tubes 21 into the chamber 20 from which it will be supplied to the burners 22. The exhaustion of the carbid in the chamber in use will be indi cated by the reduction in the size of the flame produced at the burners so that the user of the lamp will be notified in ample time to bring into operation the other gas supply chamber which is accomplished in the same manner as that above described. The exhausted chamber may then be refilled with carbid after first cutting off the water supply therefrom which is accomplished by disengaging the holder 19 from the head 14: of the valve stem which. will cause said stem to move inwardly under the tension of the spring 15 and the valve 17 to close, thus cutting off the water supply through the tube 11. This chamber will then be again ready for use and may be brought into operation when found desirable or necessary. It 1s, of course, understood that the chamber in use Wlll generate sufiicient gas to maintain in chamber 20 pressure suflicient to maintain the burners lighted during the filling of the exhaust chamber which will occupy only a few minutes.

It will thus be seen that a lamp constructed as above described may continu ously supplyv light by utilizing first one chamber andthen the other and filling the exhausted chamber after the other has been brought into operation.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of. the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while I have described the principle of operation of the invention together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

I claim I In an acetylene lamp, a cylindrical carbid container-horizontally disposed and divided transversely into a plurality of compartments, a cylindrical water tank mounted longitudinally on said container directly on the top thereof and having openings communicating with the compartments of said container, sleeves surrounding said openings and depending into said compartments, spring pressed valves for closing said openings, stems carrying said valves and projecting from said tank and extending through said sleeves with heads on their outer ends, hinged members carried by said tank for engaging said heads to hold the valves in open position against the tension of their springs, a cylindrical gas storage chamber secured to one side of said tank and arranged parallel therewith and having a burner extending laterally from its outer side, and diagonally disposed pipes connecting said chamber with the compartments of said container and operating to conduct the gas from the container to the storage chamber, and also to operate as additional supports for the storage chamber.

In testimony whereof I aflix my signature in presence of two witnesses.

HARRY GALL.
