vALvE STRUCTURE vnon AcETYLENE-LAMPS AND THE LIKE.

Specitlcaton of Letters Patent.

Patented Nov. 2, 1920.

Application led May 24, 1918. Serial No. 236,310.

l T 0 all 'w hom t may concern:

Be it known that I, GEoReE R. SHANKLTN, a citizen of the United States, residing at Springfield, in the county Iof Sangamon and State of Illinois, have invented certainnew and useful Improvements in Valve Structuresfor Acetylene-Lamps andthe like, of which the following is a description.

My invention belongs to that general class of valve devices particularly designed to control the flow or feed of fluid to the calcium carbid in acetylene gas lamps and the like. It has for its object the production of a simple and efficient device for the pur pose stated, which is reliable in its action and durable in its operation.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts,

Figure 1 is a central vertical section through an acetylene gas lamp equipped with my improvement;

Fig. 2 is an enlarged vertical sectional view of the lower end of the fluid tube and its valve;

Fig. 3 is a transverse section substantially on line 3-3 of Fig. 2;

Fig. 4 is a transverse sectional view taken on the line 4-4 of Fig. 2;

Fig. 5 is a section similar to that shown in Fig. 2 illustrating a slightly modified form; and

Fig. 6 is a transverse view taken substantially on line 6-6 of Fig. 5.'

In the drawings, 1 represents the water chamber and 2 the carbid chamber of an acetylene lamp. The two are adapted to engage one another by the usualv screw threaded connection shown at 3. The water chamber 1 is provided with the filling opening 4 provided with the cap 5. The gas released is conducted to the outlet 6, which in use is equipped with the usual tip, and if desired a reflector.

7 is a vertical water tube secured to and carried by the top of the water chamber 1, extending therethrough downward and ending well within the carbid chamber so as to be positioned within the bed of carbid therein. The lower end of the tube, as at 8, is formed with a valve seat adapted to coperate with the valve 9 carried upon the end of the rotatable valve stem 10. The upper portion of the valve stem 10 is secured to and carried by the thimble 11 in threaded engagement at 12 with the upper end of the tube 7. The upper end of the valve rod 10 is preferably bent over as at 13 to afford a convenient means for rotating the valve.

The valve 9 has rigidly secured thereto a sleeve 14 which loosely and rotatably embraces the lower' end of the tube 7 and eX- tends downward below the valve. The said sleeve is provided with slotted openings 15 substantially in line with the valve and valve seat so that the fluid released thereby may escape through the openings.

In the form shown in Figs. 5 and 6, a similar construction is illustrated, the sleeve 14 being firmly pinned to the valve 9 by pins 16, or equivalent means. In this form also the valve is reduced on two or more points as at 17 so as to permit the fluid to escape between the edge of the` valve and the sleeve at that oint, while at the same time the valve e ectively seats upon the valve seat and controls the flow of the fluid.

The operation is apparent and requires no descriptlon.

Having thus described my invention, what I claim as new and desire to secure by Let- 2. In a device of the kind described, a 100 vertical tube having a valve seat formed on the lower end thereof, in combination with a rotatable valve stem loosely extending within the tube and carrying upon its lower end a valve adapted to coperate with the 105 valve seat to control the flow of liquid, and a sleeve loosely embracingthe tube, secured to the valve, said sleeve having peripheral openings to permit the escape of fluid be tween the valve and sleeve when the valve 110 is opened.

3. In a device of the kind described, a

vertical tube havingl aV valve seat -at the lower end thereof, in combination with a rotatable valve stern loosely positioned in the tube and carrying upon the lower end a the lower end thereor` a valve adapted tocooperate with the valve seat to control the low of fluid, a sleeve loosely embracing the tube and said valve and .projecting below valve ada Jted'to seat uaon the valve seat 4an of the valve aarts'a considerable distance and to be adjustedto control the flow o'i luid,.and a sleeve loosely embracing 'the tube and secured to the valve at a point below the tube, said sleeve being open at its lower end, and being` of a length to project a considerable distance below any of the valve parts so as to space the saine from the L carbid or the like in which the tube is ern-V vertically disposed tubehaving a valve seat at the lower end thereof, a valve stein loosely positioned within the tube and having at so as to form a substantial housing therefor, said sleeve having one or more peripheral openings at a .point opposite the valve and said sleeve being secured to the valve whereby to maintain the relative position of said openings and valve regardless p of the adjustment of the latter.

ln testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
