NOZZLE FOR FILLING STATIONS.

Application filed September 26, 1925. Serial No. 58,914.

This invention relates to nozzles and more particularly to nozzles for use 1n filling stations.

It is the object of the invention to provide nozzles for use in filling stations where a hose is employed to deliver liquid from a source of supply to an automobile tank with means for controlling the flow of fluid through the nozzle, said means being readily actuated by the hand of the operator with which the nozzle is being held; and also with means to prevent the controlling means from being actuated accidentally by striking the ground or other objects when the nozzle is out of use and thereby'prevent danger of fire.

To these ends a lever comprising the controlling means is so positioned that its fulcrum is on the upper or further side of the nozzle so as to lengthen that part of the lever between the fulcrum and the point of contact with the valve stem, whereby the valve stem is given a long movement sufiicient to fully lift the valve without an unduly long movement of the handle or free end of the lever, while a guard is provided on the nozzle which prevents said lever from being operated accidentally by striking the ground or other objects when the nozzle is out of use. It is important to shorten the movement of the free end of the lever or its handle portion so that the normal position of the handle portion may be near enough to the nozzle for the hand of the operator to hold the nozzle and reach down with the fingers and lift the lever handle.

In the accompanying drawing the figure is a partial sectional view and side elevation of my improved nozzle.

In the accompanying drawing the nozzle comprises a casting 1 forming an inlet chamber 2 and an outlet chamber 3. An opening between these chambers is adapted to be closed by a valve 4 having a stem 5 travelling in a guideway formed by projections 6 in the valve ca 7 which is screwthreaded on to said casting 1, as shown at 8. A spring 9 resting against the valve head 4 at one end is held in position by the cap 7 and serves to keep the valve normally seated. A piston 10 for the valve 4 extends beyond the casting 1 and a packing gland 11 of usual form seals the casting at this point. On the upper side of the nozzle casting 1 is fulcrumed at 12 a lever 13 extending through a housing formed by the walls 14 and 15 in said casting and adapted to contact with the end of the piston 10 to lift the valve 4. This lever is rovided with a plate 16 of suitably hardene metal to afford a proper surface for withstanding the wear at'the point of contact of the piston 10 with the lever. The wall 15 of the housing serves to limit the downward movement ofthe lever 13 so that the free end of the handle portion 13* thereof will be held in a position sufficiently close to the nozzle casting 1 for the hand of the user to hold the nozzle and reach down with the fingers and lift the lever. A throw of sufficient length to fully unseat the valve 4 by a relatively short movement of the free or handle end of the lever is accomplished by reason of the fulcrum point 12 being placed at a considerable distance from the point of contact of the lever with the valve piston. These nozzles are particularly adapted for use in filling stations and may be attached to a hose in any suitable manner, as by a coupling shown at 17. A delivery spout 18 may be secured at the outlet end of the nozzle for delivering the liquid into the tank of an automobile.

When the nozzles are not in use they are often thrown on the ground or the floor and it will thus readily be seen that if the lever 13 were accidentally struck it would allow gasoline to flow out on the ground or floor and create danger of fire. In the present instance I have therefore provided a guard 19 to prevent any such accidental actuation of the lever 13 to open the valve 4. Without such guard the underwriters will not accept a device of this kind and it will therefore be apparent that this feature of the invention is of vital importance.

When in use theoperator grasps with one hand that port-ion of the nozzle adjacent the hose and by extending downwardly the fingers of said hand. may readily reach the handle portion 13 of the lever and pull it toward him, whereupon the valve a is raised against the tension of the spring 9 to permit the passage of the liquid from the source of supply to the automobile. The locating of the fulcrum of said lever at a point remote from its point of contact with the valve piston affords a long movement of the piston suflicient to fully lift the valve without an unduly long movement of the handle portion 13 and in the normal position of the thus obviatingv danger of fire; an

holding the nozz c." On the other hand when the nozzle is not in use there is no danger of accidental operation of the lever because of the guard 19.

From-the foregoing description it will .be apparent that I have provided a nozzle for use in gasoline filling stations which is prevented from being accidentally 0 erated, which may be easily and efficiently operated when In addition to the above advantages'the device is sim lo and economical to manulacture and fu fills the requirement of the Underwriters.

Having thus fully described my invention what I claim 'as newan'ddesire to secure by Letters Patent'iszfl. In a nozzle, a valve and valve stem for controlling the passage of liquid therethrough, a lever for. actuatihg said valve, and a guard to prevent the accidental actuation ofsaid lever and valve when the nozzle I its free end occupies a position sufficiently close to the nozzle that an operator ma hold the nozzle andfactuate the lever. wit

is not in use enclosing said lever, and the free end of said valve stem.

2. In -a nozzle, a valve and valve stem for controlling the passage of liquid therethrough, a lever for actuating. saidvalve,.

said lever being so formedand mounted that one hand, themovement-imparted to said lever being suflicient to fully lift the valve and a guard enclosing the end of the valve stem and a portion of saidlever actuating it and the. handle portion of saidlever.

In a nozzle, a valve for controlling the passage of liguid therethrough, -a valve -long portion of the lever between the fulcrum and the point of contact with said valve stem, whereby the valve stem is '1ven a long movement sufficient to fully, li t the valve without an unduly long movement of the free end of the lever and a guard enclosing the end of the valve stem and a portion of said lever'actuating it and the handle portion of said lever.

4. In a nozzle, a valve for controlling passage of liquid therethrou h, a lever for actuating said valve, said lever being so formed and mounted that its free end occupies a position sufiiciently close to the noz- 'zle that an o era'tor may hold the nozzle and actuate t e lever with one hand, the movement. imparted to said lever being suf-- ficient to fully lift the valve, and a guard to revent the accidental actuation of said ever when the nozzle is not inuse, said guard completely enclosing said lever.
