AUGUSTINE J. POCOCK, OF DAYTON, OHIO.

NOZZLE-VALVE.

Application filed. December 4, 1915.

To all whom it may concern:

Be it known that I, AUGUSTINE J. P0- ooox, a citizen of the United States, res1ding at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Nozzle-Valves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in valves and more particularly to an improved nozzle valve for filling the gasolene tanks of automobiles. In filling such tanks F. there is liability of overflowing because of the inability of the person operating the pump to know just exactly the amount of oil that is being delivered thereto.

The object of the present invention is to provide a nozzle valve having structural features as hereinafter described and claimed whereby a quick, positive and reliable manipulation of the valve is obtainable.

The invention will be more fully described in detail in connection with the accompanying drawings.

Referring briefly to the accompanying drawings, Figure 1 is an elevation of my improved nozzle valve; Fig. 2 is a section thereof on the line a-a of Fig. 1; Fig. 3 is an elevation of the stuffing box and valveoperating parts removed from the nozzle.

In a detail description of the device, similar reference characters indicate the same parts in the several illustrations.

The receiving branch 1 and the discharge branch 2 constitute the casing or body of the nozzle, the former being provided with internal screw-threads for connection with the flexible pipe leading from the source of supply. The discharge branch 2 has a suitable number of surface projections 3 for the convenient attachment of a reducer or discharge spout i which is adapted for insertion into the inlet opening of the tank to be filled. At the entrance to the discharge branch of the nozzle, a puppet valve 5 is located and cooperates with a seat 6, said valve having extensions or wings 7 which at all times lie within the entrance to said discharge branch and serve to guide the Specification of Letters Patent.

Serial No. 64,977.

Astem 8 is united to said valve and extends through a stuffmg box 9 provided in a cap 10. The cap 20 has an exteriorly screw-threaded extension 11 which unites the cap with an openlng above the valve and an annular flange 12 engages a packing gland 13 and the union between the cap and the upper branch of the nozzle is effectually sealed. The top of the cap 10 is provided with two oppositely positioned lugs or offsets 14;, portions of the upper ends of which are tapered as at 15 and other portions are straight as at 16. The stufling box cap 10 issurmounted by a cupshaped member 17 having an annular knurled surface 18 which the fingers grip in turning said member. The said cupshaped member 17 is pinned to the upper end of the valve stem 8 and forms the upper closure of the stuffing box. The lower end of the member 17 has oppositely disposed cam surfaces 19 and 20 which co-act with the lugs or offsets 14 in opening the valve and maintaining it open. The deepest part of each of said cam surfaces terminates in a straight surface 21 and a stop 22. In turning the stem and the valve therewith from the closed position of the valve, the cam surfaces 19 and 20 ride on the tapered surfaces 15 of the lugs 14, and the continued movement of the member 17 causes the straight surfaces 21 to ride onto the straight surfaces 16 of said lugs which is the limit of the movement of said member 17 in that direction owing to the stops 22. At this time the valve is maintained open. In order to permit the spring 23 to close said valve, a very slight movement of the member 17 will bring the straight surfaces 16 and 21 out of contact and the valve will be instantly closed by the spring, the extent of said movement being equal to the length of the straight surface 16 which it will be observed is small.

Having described my invention, I claim.

In a valve of the character specified, a member forming a liquid discharge passage, a valve controlling said passage, a stem extending from said valve, a screw-cap mounted upon said member and having an upwardly extended portion forming a stuifing gland for'the valve stem, said screw-cap having lugs extending laterally from opposite sides of the stuffing gland portion of said cap, the upper ends of said lugs having cam and straight surfaces, an upper cap mounted above said screw-cap to which the valve stem is connected, said upper cap having oppositely disposed cam surfaces Which terminate in straight surfaces and downwardly extending stop surfaces at the terminals of said straight surfaces, the said 0ppositely disposed cam surfaces cooperating with the cam surfaces of the lugs of the screw-cap in opening the valve and the 0 straight surfaces cooperating With the AUGUSTINE J. POCOCK.
