Application filed May 6, 1912. Serial No. 6925,4694

To all whom it may; concern:

lie it known that '1, MARTIN NILLIAM Moons, a citizen of tnc United States, residing at Springfield. in the county of Banga- 111011 and State of Illinois, have invented certain new and useful Improvements in Acetylene-Gus'iiainps; and I do declare the a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it uppert-uins to make and use the same.

This invention relates to improvements in acetylene lamps.

(l ne object. ot the invention is to provide a lump of this character which'is particularly adapted for the use of miners and which is provided with an improved construction and arrangement of feeding mechanism whereby the water from the ervoir of the hump is controllecl'and discharged into the generating chamberin the desired quantities.

With this and other objects in view, the invention consists of certain novel features of construction, and the combination andarrangement of parts as will be more fully described and claimed.

1n the accompanying drawings; Figure l is a central vertical sectional view of my iniprovcd lamp; Fig. 2 is'a horizontal sectional view thereof, taken on the line 2--2 of Fig. 1; Fig. 3 is a detail perspective view of the supporting plate for the perforated water distributing cup of the lamp.

My improved lamp comprises a base section 1 which contains the carbid and forms the gas generating chamber of the lump. The base section 1 is threaded cxteriorly at its upper end and onto said threaded portion is screwed a gas chamber 2 which is in the form of an inverted cup and has its sides bent outwardly to form radially disposed annular recess 3. The lower end of the mp2 forming the gas chamber is threaded inte'orly as 1 and is adapted to be down onto the threaded upper end of the base section 1. in the annular recess 8 of the chamber 2 and engaged with the upper edge oi the base section 1 is a gasket 5 and between the gasket and the upper wall of the recess 3 is clamped the outer edge of a gas filtering screen 5 which extends across and covers the lower end of the chamber 2 as shown. The gasket 5 forms a gas tight connection between the chamber 2 and the upper end of the generating chamber formed by the base '1.

Secured to and having a fluid tight engagement with the sides of the cap-forming the chamber 2 is a water reservoir 7 indie upper end of which is arranged-a filling opening 8 normally closed by a screw plug 9 as shown. Secured to one side of the lower portion or" the water reservoir 7 is a reflector 10 and arranged through the lower portion of the reflector and through theudjacent sides of the reservoir 7 and gas clrambcr2is a gas discharging tube '11 in the outerend of which is secured a burner 12.

Arranged in the bottom of'the base section or generating chamber 1 of the' lar'np is a cup supportingplate 13 having thereon a centrally disposed I upwardly projecting cir cular boss'ld which ispreferably struck up i'roin the-plate 13 as shown. =Engaged but detaohably connected with theiboss when the plate 13 is a perforated water distributing cup 15 which projects. upwardly to a suitable distance in the generating chamber. Arranged in the center of the reservoir 7 and extending downwardly through the cap 2 forming the gas chamber and having its lower end projecting into the water distributing cup to a point near the lower end thereof is a water conducting tube 16 in the lower end of which is formed a tapered valve seat 17. In the tube 16 adjacent to the bottom of the reservoir 7 or upper side of the cap 2 are water discharging passages 18 of which there maybe any suitable number and through which the water from the reservoir 7 discharges into the tube 6.

The upper end of the tube 16 is closed and has therein a threaded passage 19 with which is engaged the threaded upper end of a valve stem 20 which is disposed in the tube 16 and has on its lower end a conical shaped valve 20 which is adapted to be engaged with the seat the tube whereby the latter is opened and closed to permit the discharge of water from the tube into the distributing cup 15. The water when thus discharged into the distributing cup 15 passes through the discharge openings therein onto the carbid in the lower portion of the generating chamher. The water in discharging apertures in the cup 15 will be evenly distributed onto the carbid and by PI'OVldlIlD' the valve 21 as herein shown and described 17 in the lower end of.
