Patented June 11, 1935 UNITED STATES PATENT OFFICE 2,004,203 SPOU'I FOR HOSE NOZZLES James W.Howell, Chickasha, Okla. Application March 25, 1935, Serial No. 12,939 2 Claims. (01. 221-34) My invention relates to improvements in spout for hose nozzle especially adapted for use in dis-- pensing gasoline.

The principal objects of my invention are to provide a device of this character which is positive in action, simple and inexpemive in COIL- struction; new, novel, and easily operated; which is strong, durable, reliable and of evident utility; which cannot easily get out of order and is efiicient for the purposes for which it is intended; to provide a non-drip valve at the extreme end of the spout but under control of the hand lever similar to that now in common use on gasoline dispensing nozzles; to provide a renewable valve seat for threaded connection at the outlet end of the spout together with a fiber valve and spider guide for securely closing the spout; to provide a coil spring within said spout for positively seating the said valve; to provide connecting mechanism between said valve and hand lever for opening the valve when dispensing gasoline.

With these and other objects in View my illvention consists of the construction, novel features and combination of parts hereinafter more fully described, illustrated in the accompanying one-sheet drawing and pointed out in the claims hereto appended. Various changes in the form, proportion, size, shape, weight and minor details of construction, within the scope of my invention may be resorted to without departing from the spirit or broad principle of my invention or yielding any of its benefits.

In the accompanying drawing, Figure 1 is a side View of the device in section; Figure 2 is an exterior side View and Figure 3 is a section on the line 3-3 of Figure 1.

In the following description like reference numbers designate like parts in all the figures, and it is to be understood that the drawing is to be interpreted as being illustrative and not restrictive.

The nozzles in common use at the present time are very unsatisfactory due to the position of the faucet or cut-01f valve. The faucet is about a foot back of the outlet end of the spout and when it is shut off there is always some gasoline adhering to the inner surface of the said spout due to skin friction. It requires some little time for all of this gasoline to drain out of the spout and usually the filling station attendant does not wait for this to take place but removes the spout from the gas tank intake and drips the fluid over the highly polished surface of the automobile. This soon dulls the finish and ruins the appearance of the car.

My improved spout is so constructed that the cut-off valve is at the extreme end instead of some twelve or fifteen inches back of said end. It closes the outlet so there is no spout to drain and no time is lost in waiting for the cut-off to become effective and best of all, there is no gaso-, line to drip over the finished surface of any. part of the car.

One embodiment of my invention is shown as follows: Connecting body or frame I is threaded at 2 for coupling to hose 3. Curved spout 4 is threaded at 5 into body I and is provided with hexagonal facets 6. Operating lever l is hinged to body I by means of lug 8 and bifurcation 9. Guard in has a slotted guide H for the free end of lever l. Hinge plates l2 are pivoted to bolt connection I 3 which has vertical movement in slotted opening [5 in lever 1. Lock nutsl4 on bolt connection l3 provide for longitudinal adjustment to the position of pull rod l6. Said rod 16 passes through packing nut I! and is sealed against leakage by packing material H3. The inner end of pull rod I6 is attached to valve operating chain I9 which passes over pulley 20 and between stop pins 22, the latter serving as stops for the upper end of coiled compression spring 2i. Chain I9 is threaded through the coils of spring 2! and at its lower end is secured to valve stem 23 upon which is seated valve 24 and spider 25, the latter two members being securely held in place by nut 26. Valve seat bushing 2! is threaded into the lower end of spout 4 at 28 and the outer surface of said valve seat bushing 27 is knurled at 29 so as to be easily removed by hand. Valve 24 may be fiber or other suitable material. Spout 4 will preferably be made of brass and members I6, I9, 20, 2|, 22, 23, 25, 26, and 21 may be of brass or any suitable material not subject to corrosion or deterioration due to contact with, and immersion in gasoline.

As can be readily seen in Fig. l the parts subject to wear, namely valve 24 and valve seat 21, are so located as to be removed and replaced with a minimum expenditure of time and effort. Both are accessible without disturbing any other part of my improved spout. The valve 24 is under pressure from spring 2| and is guided into perfect alinement for seating in member 21 by spider guide 25. The said valve 24 is also urged into seating position from the pressure exerted by the gasoline seeking to escape from spout 4. When lever is released, after being actuated to allow gasoline to flow out of spout 4, the combined pressures of said gasoline and spring 2| will cause the valve 24 to close instantly and as riding over a pulley located within the upper there is no open pipe or spout beyond the valve there can be no drip as occurs with the spout now in use as hereinbefore elucidated.

The operation of my improved spout is self evident but will be explained briefly. As viewed in Fig. 1, when lever I is actuated in the direction indicated by the arrow 30, pull rod IE will be moved to the left and through the connecting chain I!) will open valve 24 against the pressure of spring 2|. Gasoline will flow out through the apertures between the wall of spout 4 and the cross arms of spider guide 25. (See Fig. 3.) When lever l is released, valve 24 will close instantly and prevent any dripping of gasoline from the end of spout 4.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is: I

1. In a device of the class described, in combination, a frame for connecting a hose to a spout, a spout having an'arcuate section intermediate its ends, said spout being threaded into said frame, a lever hinged to said frame and protected by a guard having a slot for directing the movement of the free end of the said lever in one plane, an adjustable bolt and hinge plate means for connecting said lever with a pull rod extending through a packing nut in the said frame and into the upper end of the said spout, a chain attached to the inner end of the said pull rod and end of the said spout, said chain being threaded through a coiled compression spring within the arcuate section of the said spout, pins through the said spout forming a stop for the said spring, the lower end of the said chain being attached to a valve stem supporting a spider guide which forms the lower stop for the said spring, and a valve for seating in a valve seat bushing screwed into the lower end of the said spout, the said bushing having a knurled outer surface to facilitate its removal by hand.

2. In a device of the class describe, in combination, a connecting body or frame having coupling means for a hose, a spout in threaded connection with said frame opposite to said hose coupling, hexagonal faced means on said spout for screwing the said spout into the said frame, the said spout having an arcuate section intermediate its ends, a lever in hinged connection with said frame, a guard on the said frame for protecting the said lever, the said guard having a slot for guiding the free end of the said lever so as to have movement in one plane only, a bolt connection adapted for seating in a slotted hole in the said lever and provided with adjusting lock nuts, a pull rod, hinge plates connecting said bolt and said rod, the rod'extending through a packing nut and into the upper end of the said spout, the said lever being adapted to reciprocate the said rod through the said frame and within the said spout, a chain for attachment to the inner end of the said rod, a pulley within the upper end of the said spout immediately adjacent the inner end of the said rod over which the said chain has movement, a coiled compression spring seated within the said spout and surrounding the said chain, pins through the said spout as a stop for the upper end of the said spring, a valve stem within the lower end of the spring. and attached to the lower end of the said chain, a spider guide and valve seated on the said stem and under compression of the said spring and a valve seat bushing in threaded connection with the lower we end of the said spout for registering with the said valve, the said bushing having a knurled outer surface to facilitate its removal by hand.
