MINERS LAMP.

specification of LettersPatent. Patented Nov, 22, 1910.

Application filed April 23, 1910. Serial No. 557,195. I

To all whom it may concern:

Be it known that I, MARTIN JAMES Gun- 'l'lS, a citizen of the United States, residing at Billings, in the county of Yellowstone and State of Montana, have invented certain rangement of parts forming the generating vessel and novel means for supporting a lamp thereon.

A st1lL further object is to provide means for supporting the lamp upon the cap or the user.

Other objects and advantages will be apparent from the following description, and

it will be understood that changes in the specific structure shown and described may be made within the scope of the claims with out departing from the spirit of the invention.

In the drawings, Figure l is a side elevation of my improved lamp, in posit-ion for use, Fig. 2 is a vertical central sectional View taken on the line 3-3 of Fig. 3, Fig. 3 is a top plan view of the device, Fig. 4e is a detail view of the supporting bracket for the burner globe, Fig. 5 is a detail view of a retaining member for the top of the globe.

Referring to the drawings in which like characters denote like parts, 1 have shown my improved miners lamp, which comprises the carbid reservoir 10, which as more particularly shown in Fig. 2 of the drawings I has a concaved inner face ada ted to con form tothe shape of the cap Q the wearer, the outer and side faces of the reservoir being angular in cross section, said reservoir having attached to, its concaved inner surface, a depending pin. 11 adapted for securing the device tothe cap in the usual manner. The reservoir is adapted to contain the.

carbid in granular form and is provided with a screw cap 12, through the med um of which the carbid is fed to the reservoir.

Disposed upon the upper wall of the reservoir and depending into an opening'therein is a water tank 13, which is supported upon the upper wall of the reservoir as by means of an annular flanged ring 14, which is secured to the tank and the reservoir and. said tank is also provided with a screw cap l5 through which water may be poured into the tank. The lower end of the tank 13 is slightly conical and has an extension 16 of reduced diameter and having a central bore 17 and a conical valve seat 18,-said bore being opened or closed as desired by means of an operating stem 19 having a corresponding"conical end adapted to be received in the seat 18 and thereby regulate the amount of water discharged from the water tank.

The stem 19 extends through the outer wall of the reservoir and is providedv with an operating head 20. i

Extending outwardly from the outer wall of the reservoir there is a suitable bracket 21 having a suitable angular brace member 22 secured thereto, the outer end of said bracket being adapted to support a cylindrical base 23, said jacket having a central aperture 24' through which a burner pipe25 is extended, said pipe being in communication with the reservoir above the operating stein 19 and extending at an angle to beneath said cylindrical base and more especially the aperture therethrough. The burner pipe is adapted to convey the gas generated within the reservoir to the burner and a valve 26 of the usual type is provided for regulating the flow-thereof, it being understood that the carbid is poured into the reservoir through the opening therein and the water tank similarly filled with water,

the valve stem is then operated to allow. the

water to drip very slowly from the tank so a proper amount of gas will be generated and flow through the burner pipe, for all useful purposes.

Supported upon the cylindrical base 23 is a burner globe 27, which is preferably of glass and adapted to be positioned at a slight distance from the reservoir, the burner being adapted to extend upwardly a slight distance within the globe. To prevent the globe from becoming displaced upon the cylindrical base 23 I provide a spring keeper which comprises an arm 28, which is secured to the upper end of the water tank, the outer end of said arm being bent to form a de- I pair of cross arms 30 having depending ends match or the like may be inserted underneath the globe.

- From the foregoing it will be seen that I have provided a miners lamp which can be very cheaply manufactured and one which will be very desirable for such use, inasmuch as there is small liability of the same catching fire, thereby avoiding accidents usually occurrin from this cause.

What is claimed is:

1. A miners lamp comprising a gas supply reservoir, a bracket secured adj acent the bottom of the front wall of the reservoir. and having a pair of openingstherethrough, a burner pipe extending from the reservoir, said pipe being disposed downwardly through one of said openings and upwardly through the other of said openings, a burner carried thereby, a globe supported upon said bracket and a keeper secured to the top of the reservoir and engaged with the upper end of theglobe to hold the same in position.

2. A miners lamp comprising a suitable gas generating vessel, having means for securing the'same to the cap of the user, a

' supporting bracket secured to the vessel and extending outwardly therefrom, said bracket havmg a circular base upon its outer end provided with an annular groove, a valve controlled burner carryin pi e in communication with the vesse m extending throu h the base, a globe having an enlarge upper portion and a restricted lonier end seated in said roove, and means bracing the globe at its upper end.

3. A lamp comprising a suitable generatfor - ing vessel for gas, saidvessel having a concaved inner surface, means secured to said surface for attaching the same to an object a bracket secured to the lower front wall of said vessel, a cylindrical base carried by said bracket, said base having a central aperture therethrough, a burner pipe extendingfrom said vessel and adapted to convey gas therefrom, said burner pipe extending u wardly through said aperture and provide with a suitable burner, a valve in said pipe for regulating the supply of as, a globe supported upon said base an over the burner and a spring keeper secured to said generat-
