F!LLING=NOZZL FOR f'LUlDml-iOLDiNG TANKS.

SPECFICATION forming part of Letters Patent No. 696,736, dated April 1, 1902.

Application iiled May 31,1901.

To cir/ZZ whom it may concern:

Be it known that I, FRANK WALTER How- ARD, a citizen of the United States, residing at the borough of Brooklyn, city and State of New York, have invented an Improvement in Filling-Nozzles for Fluid-Holding Tanks, of which the following .is a specification. l

My invention relates particularly to fillingnozzles for tanks holding such iiuids as gasolene, naphtha, and kerosene.

The object of my invention is to provide a valve of simple form that isbcth iiuid and vapor tight and that does not project from the tank.

In myimprovernent the valve-case is ,tubular and open-ended, with a liaring mouth at one end and exteriorly threaded and perforated at the other end and with a central contracted neck forming a guide for the X-stem of the valve. The threaded end is covered With a cap forming a seat for one end of a spring and the other end of which spring seats against the valve. The outward force ofthe spring holds the valve firmly to its seat. The valve-case is secured to the fluid-holding tank at a flange surrounding its flaring mouth, and the tank may be filled by simply pressing down the valve and holding the same While the fluid is being poured into the tank, the iiaring mouth preventing the fluid spilling.

In the drawings, Figure l is an elevation, Fig. 2 a plan, Fig. 3 a vertical section, and Fig. 4 a sectional plan at the line ai o; ol' Fig. 3, illustrating my improvement.

The valve-case or tubular body is made With a iiaring mouth a, having a surrounding flange 2; a contracted neck ct at the eenter of the case; an open end nickt-elderly threaded at 3 and provided With perforations 4. The valve-case is thus open-ended. A cap h, interiorly threaded, screws.- upon the threaded portion 3 of the valve-case and closes this end of the case, and said cap is provided with a cup-seat 5 for one end of the spring c.

The valve-body d is provided with a beveled periphery contacting with a beveled seat at the lower end of the contracted neck a', and these parts are preferably ground and fitted to forni a close joint. The valve-body is preferably provided with an X valve-stem Serial No. 62,540. (No model.)

CZ, closely iitting and received Within the con-a tracted neck a and the neck forming a guide for the valve.

'A cup-seat 6 is formed on the under side of the valve-body d to receive the upper end of the spring o, and e represents the top of the metal fluid-holding tank, within which the valve-case is received and to which the same is soldered at the flange 2. The spring c normally maintains the valve-body in an elevated position to its seat in the valve-case, so as to close oft the exit of fluid or vapor. When the tank is to be filled, the end of a funnel or noz- Zle may be pressed against the upper surface of the ,l-stem and by the same the valve be depressed, so as to permit of the entrance of fluid into the tank, whichpassing down the valve-case, inds an exit into the tank through the perforations 4, the valve at once closing after pressure upon the stem has been released. This valve is especially adapted for use with motor-vehicle tanks where a supply of iiuid is carried for use in actuating the motor mechanism, it being absolutely essential in thisV class of tanks that the filling-valve be iiuid and vapor tight. The Haring mouth has the further advantages of preventing the spillingoi:` the liquid and consequent loss when the funnel is inserted and the liquid passes through the funnel and through the fillingnozzle into the tank; also, the opening in the tank Where the flange 2 is secured thereto is sufficiently large to pass therethrough all of the nozzle below the lian ge, so that the device in its entirety is readily inserted and secured in place.

l claim as my inventionl. A filling-nozzle for fluid-holding tanks, comprising an open-ended valve-case having a iiaring mouth, a reduced cylindrical neck with a valve-seat at the end thereof and an enlarged threaded end portion with openings therein, a valve having an integral .l-stem which iits the said reduced neck, a cap iitting upon and covering the enlarged end portion of the valve-case, and a spring between the said valve and cap, substantially as specified.r
