,Troll wfwmzftmayconuem Y Be it'known that I, ,FREDERICK Sceau LENBERG, a citizen ofthe United States, residingV at Lima, in the county of reellen, State of Ohio, have yinventedcertainvnew and useful Improvements in Oil Valves; and I do hereby .declare the following to be 1a full, clear., .and` enactt@descriptionY of the invention, lsi i elias, will enable 'others skilled .10 1in the art to which it iappertans to .make and use thesame. l i

This invention relates ,to new and useful improvements in lvalves and particularly .to valves for, CQIitrolling thev flow of liquid or gaseous fuel. lThe particular yadaptation oi' 4the' valve is (for -oilor gas-burning cook :stoves 011e obj-ect. ci' the invention ist@ provide a valvev of this :character having means yfor ilimitingthe opening :and closing movement thereof. Y

Another object of' the invention is Lto provide xa valve off this character )having an 1 adjustable sto-p l'onilimitigng the opening movement .of the-valve Aliieyond the starting position or that position wherein l-the fuel .is permitted :to flow to the bujrner.

' 'A further object is to provide a valve with which is associatedfa Sight-feed 112W- .ing a priming .means formed integrally therewith. Y Y Y l A still lfurther' object isto provideV .a novel valve of this character having1a packiing and a -bushingso constructed 4and .arrangedthat the packinggcan `be forced `into close embracing irelation to f the stem of -the valve.

Other objectsand advantages .willbe apt parent iromzthe following description when 0 taken in connection with the accompanying drawing. Y i y In fthedrawing: y i

through the valve on the line 4 4 of Figure l, which line is parallel to the line 2-2.

Figure 5 is a longitudinal sectional detailed view through the handle 'and locking i plunger.

`Referring particularly to the accompanying drawing 10 represents the body of the valve which has the fuel ,inlet passage ll `extending.; inwardly from one side vand `having the threaded nipple --1 2 for attachment to the fuelmanifold 13. v Formed vertically through the body of the valve `is a passage 14,. VSaid passage being reduced to form the shoulder l5, on which rests ,the

stem .is formed with a tapered point 22 which .seatsin thveeconical seat23.YV A prortion of this seat is `:formed withinthe conical boss 24, which is formed `integrally with the valve body and projects downwardly from the center thereof. As clearly shown, the passage 11 communicates with the lower portion of the passage l4,-so that when the Aneedle .valvestem 2() is elevated its point 'isfunseated, andthe fuel will pass downwardly and drop from the lower end of the boss 24. A cap nut25 is screwedionthethrejaded neck 26, which is formedon the upper side of thevalve body, and `is arranged t@ drive the bushing 18 downwardly ,against the packing 1,6 when The Vstem 2O is vrotatably vdisposed through this cap.

Detachably secu-red to the upper endof the stem 20 is a laterally extending handle 27,the same being` .secured thereto by inea-ns lof Vthe isere/w28. Secured to `the upper tace of the valve 'boi-fly, and receiving the neck 26 upwardly therethrough, is a dial plate 29,'i1he :same beingk ,slightly Aless Lthan :a coinplete circle. This disk `secured to the valve `body by :meanscf ,the screws 30.

Formed in the dial plate 29, adjacent one end Vof the flat edge thereof, isa depression- 31, andv at a point approximately 135" from the depression 3l is another similar depression 32. Extending radially from the attaching .portion of the handle,at a ,point` diametrically opposite to the handle is an arm 33, and formed on the outer end of this arm is a downwardly extending ltubular member 34, within which is disposed the spring pressed plunger 35, the spr1ng35 of which `normally urges the lower end of the plunger into contact with the upper face of the dial plate 29, said plunderbeing arranged to drop into the said depressionBl or 32V according tothe position of thehandle and valve stem.

Projecting from the lower end oi' thetubul lar member 34 is a nose 36, to which refer:

In' the edge of the dial plate 29 are formed the series of notches 37, said series beginning at thedepression 32 and extending around from the depression .31.

ina direction toward the flat portionY of the edge ofthe plate and in a'direction away Engaged on the neck 26 for rotation is acollar 38, this collar being split and having itsends extending outwardly as shown at 39, and receiving therethrough a pivot pin 40, for supporting the L-shaped member or latch 4l, VVdisposed Vbetween said ends.

The intermediate portions of the ends 39 are outwardly and oppositely bowed as at 42 to provide a tubular socket for thecoil spring 43. The 'upper end of thiscoil spring bears against the lower face ofthe dial plate 29', while its lower end bears on the upper ledge of the horizontal leg of the L-shaped'member 41, to rock said L-shaped member and engage its lvertical leg in one or another of the notchesl this body, and extending-laterally `and then Vcurving upwardly, is the pipe 48, ,which `has its upper end enlarged into the form of a cup or bowl 49. Into this cup or bowl 49V is adapted to be poured oil or Agasoline. for the purpose of primingthe burner, with which the Vvalve is used. A removable .closure -or this cup consists oi'a fiat disk 50 Vhaving dependingleg's 51, which are sofarl ranged as to rest within the mouth of the Vcup and hold the disk slightly elevatedthereabove, to permit air to pass through the cup. Screwed into the lower end of the body 45 is the oil conveyingrpipe 52, which conveys oil to the burner. Y

In the operationl of Vthe device when the ofthehandle 1 plunger 35 is seated within the depression Y Y 3l, the needle valve is rmly seated on the :Y
