T all 'whom t may] concern:

"Be it known that l, JOHN P. Reinheim, a citizen of the United States, residing at Lorain, 'in the county of Lorain and State 5 o :(hio, hare .invented a certain new `and useful Improvement Iin Gas-Valve Structures, of whichthe following is a full, clear, and exact description. j This invention relates to a gas regulating .10 valve for use in connection with gas burners. The object ot the-invention is to provide a 'burner in which the How oit gas is controlled by an insideadjustable member which is easily accessible for regulating purposes. i i I Reference should be hadto the accompanying drawing forming a part of ythis specification in which the ligure is a sectional eleva-` tion.

Referring to the 'drawing7 1 indicates a body "portionwhich has an extension l2 which `isthreaded, as indicated at 3, thisportion being adapted toi-connection yto `the feed pipe o a stove,`or the feedjgas `pipe of any construction in connection with which the herein described device may be used. dlherc is also an rextension at right angles to the extension l2 whichis indicated 'at 4. This efr-tension is hollow,fand at its outer end is `providedwith an Aexit opening `The end of the extension 4 terminates inl aconical slanting portion 67 which may .be generally 'speaking conical in shape, and the opening 5 is atthe upper or end `portion of the slanting parte. Upon the `outer surface of the extension l there are threads 7, and upon these threads there is la nut 8. This nut `may be adjusted to any desired position upon the thread 7, thereby determining the dis- 10` tance which the extension e will extend inside ot the `mixer of the usual burner.

There is an axial passageway 9 which extends through the extension 2 and it communicates with an enlarged chamber 10 which is formed in the member 1. The member l and the extension l are hollow, and threaded into an opening 1a at the lower` portion of the body 1 is a threaded barrel portion 11. Extending from this barrel portion is a hollow tubular part 12 which is provided withopenings 13, at a portion thereof so that they communicate with the chamber 10, and gas which passes through the passageway 9 and to the chamber 10 will,

i5 at une rcp thereof, and ,with a plurality of openings 116 for-med in the conical wall portions j The member 11 `and the tubular member 12 are capable of adjustment within the member 1, this adjustment being elleo-ted by inea-ns of a knurled 'Ahead portion lf? which 1s formed as a part of or `connected to the barrel portion 11. A 'lock nut l1-8 is threaded upon the 4threads ofthe .outer-surface of the barrel portion l1, and is adapted to engage with the `lower end oit the body portion -lso as to 'hold the barrel part 11 and the hollow tubular portion 12 in any adjusted position. Whenthe tubular -meinber 12 *is extended to its nmost outward position the conical portion will entend up into the opening and the conical walls of the member 12 will engage w-iththe edgeofrthe opening l5 so that gas passing through the tubular member 12 can find exitfonly through the opening 15. r

lf `it be desired-torv supply more gasthrough moved linwardly in the4 manner before ydescribed, .so that the conical 4wall 'portion 14 is `out Aof engagement with the lower Vorinner edge `of fthe opening 5, and runder-these conditions .gas may pass through fthe ope`nings 16 and `around the 4outside of the Lconi-l cal portion 11i, andl through the 4orifice The extent to which gas may thus flow will, of course, depend upon the clearance between the conical portion 14C and the inner edge of the orifice l.

It will be noted that the adjustable tubular member 12 will at its outer end be guided by theinner walls of the extension i so that the co-operation between the conical portion 14 and the outlet 5 will be assured.

By the structure which has just been described the member necessary to be moved in effecting an adjustment for the quantity of gas to be delivered, is readily accessible being entirely beyond the pipe which feeds gas through the valve structure.

The arrangement of parts which has been described also has the advantage of increa`sing the flow of gas to its maximum capacity because of the tact that the orifice in the the orifice 15 then the tubular member 12`is for entraining air as it passes into the mixer of a burner.

Having described my invention, l claim 1. A gas valve comprising a tubular body having at one end a tapering wall provided with an axial vdischarge opening and a gas inlet adjacent the opposite end, a tubular member within said body and adjustable longitudinally thereof, said tubular inember being of less diameter externally than i, the internal diameter of the body whereby an annular passageway from the inlet to the discharge opening is provided upon the exterior of the tubular member, said tubular member having openings in the wall thereof establishing communication with said passageway and a tapering end portion adapted to be moved into engagement with the discharge end of the body to close said annular passageway, said end portion of the tubular member having an axial opening of less diameter than the discharge opening of the body.

2. A gas valve comprising a tubular body having an end wall provided with a conical Y inner surface and an axial discharge opening, said body having a lateral gas inlet, a tubular member within said body and adjustable longitudinally thereof, said tubular member being of less diameter than the tubular body whereby an annular passage i way is formed between said tubular membei' and tubular body, said tubular member having a closed lower end which fits within the'lower end of the body and forms a closure therefor, said tubular member having openings communicating with the passageway and a conical end portion adapted to engage in the discharge opening of the body 3. A valve comprising a body portion having an extension with a gas passage therethrough and capable of being connected with a gas feed pipe, said body portion having an opening at right angles to the extension just mentioned, and having a hollow extension which is in alignment with the opening in the body portion just mentioned, said extension at its upper end having a slanting wall portion and an outlet orifice which is centrally disposed with respect to said extension, a movable tubular member within said hollow extension said tubular member being guided in its movement by the inner walls of said extension of the body portion said tubular member at its outer end having slaiitiiig walls, with an orifice which is in axial alignment with the outlet orifice before mentioned, the said slanting walls having openings which are not in alignment, said tubular member at the end thereof being provided with openings which communicate with the gas passageway in the first mentioned extension for the body portion', a barrel portion connected with the tubular member said barrel portion having a threaded exterior and-- which it co-operates to control the passageof gas therethrough.

ln testimony whereof, I hereunto affix my signature.
