Annegummea :mbar 1, 19a?. siem m. saam( This inventionrelates nozzles for filling of motor vehicles. The object of this invention is to provide sucha nozzle with a valve to close the passage -a valve stem whic through the nozzle when it is desired to re- :nove the same from the tank. 4

e principal features of my invention consist 1n a sprin pressed valve,` guided by will seat itself when released, and stop the ow of gasoline theres through. Y y a These and other features of my invention are h'eremafterl described and are illustrated in the accompanying drawings, in which:

Figure' 1 is a longitudinal central section of my improved nozzle.

k:from the wall a of position therein as indicated Figure 2 is a side elevation of the valve stem of my improved nozzle, with'the valve thereon in sectlon on an enlarged scale.

Figure 3 is aside elevation of the'valve operating ltrigger of my improved nozzle showing the stung box thereon in'longitudinal central sectlon on an enlarged scale.

In these drawings A indicatesthe housing of my improved nozzle having an angular inlet stem A ada ted to be secured toa hose (not shown) lea ing from the usual-pump mechanism (not shown). v

mdicates 'a valve chamber, the rear end of which is closed by a closure plug B. C indicates a lpas'sa'ilge from the va ve chamber B to the nozzle C indicates/the chamber containing the valve operatin lever C. Slidably mounted in guides E. depending the housing A, is a valve stem 'F on which is lexibly securedva valve F see Fig. 2; The valve stem F is rovided with a head f. Upon the stemF place a sleeve f which is prow'ded with external threads ada ted to elgage the internal,

threads f o the valve Between and the internal annular shoulder s of the sleevef, is a'helical spring f whic presses the head f of the valvestem F againstfthe inner wall of the valveF. Against the G of resilient in ,place by a being pressed washer G said washer G against the packing disk G- by the 'head of the sleeve f. The opening through the sleeve f is of a greater diameter than the valve stem so that said stenican assume an angular by broken lines 1n F1 2. By meansv of` this flexible construction the valve is free to. adjust itself wall ofthe chamber C in which J ndicates the body whichis screwed into the rear-wallthreads j to press the the head ,f of the valve stem the end of the assage C, is a valve operating lever C2, whic is mounted upon a` ipv'ot 0 1n the upper iartofy the chamber said lever C2 exten ing downward across the end the free end of saidj lever seat. vWithin the chamber C at C2 bein engaged by a roller I-I inthe slidable i trigger see Fig. 3. The slidable trigger H .passes packing box secured in the .rear

C8. The body member J is provided with packing J through which the trigger H passes. "Upon the tri ger Il I place a gland sleeve J 2 and I provi e a cap J8 with internal threads adaptedto be screwed over the gland sleeve J 2 against vJ". AThe roller H is mounted 1n a slot,v not shown) and the end of the lever C* extends through said. slot and engages said roller so that when the hook it of said trigger I-Iis pulled backward the lever C2 iscaused to swing against the end of the valve stem which causes the packin is "raised on' o to ow throu h rearward from the chamber C'.

the valve l" to move 'away from the valve seat to its standin The ends ol t e' tually seals the joint between said tube and i the housing lA.

Having thus fully described m so that the same can be utilized' by others I do `not desire to be limited to the exact construction shown and described as many modilieations can be parting from the scope of myinvention therefore what I claim as new"and desire tov secure by Letters Patent is:

1. In a device of the class described, a valve housing having ay passage therethrough,` an annular valve seat sage, valve stem guides extending transversely into said passage, a valve stemsupported in said guides, a ea valve having a screw threaded cavit to receive said head', asleeve having its interior diameter greater than the diameter of said invention y made therein without de` shoulder around said pas p d on said valve stem, a i
