VALVE-CONTROLLED FILLING NOZZLE.

Application filed November 27, 1926. Serial No. 151,234;

This invention relates to valve controlled filling devices of the type adapted for use at gasoline filling stations and the like, and has for an object the provision of a balanced and simply operated device.

Another object is to provide a device of this kind having a convenient handle menr her which serves to facilitate handling of the device, and which also serves as a guard for precluding accidental actuation ot the valve.

Another object is to provide a device for thepurpose stated which is controllable with one hand, and in which the handle cooperates with the hand of the operator in exercising line control of the valve.

These and other objects are attained by the means described herein and disclosed in the accompanying drawing, in which:

The figure is a side elevational view of a device of the invention, the part being shown in cross section. The deviceconiprises a hollow casing body 5 provided at its one end (5 with a threadedly connecting coupling i. The coupling 7 carries an open web or spider 8 having a centrally periorated sleeve 9 in which one end 10 of a valve stem 11 is slid-ably retained. The opposite end 12 ot' the valve stem ll is reciprocally retained in a spud or suitably packed bonnet structure 13. The bonnet 13 is screw threaded into a'threaded perforation M in the end of casing 5 opposite the coupling end 7. lnteriorly of the casing 5 is providcd a valve seat 15 controlled by a valve 16 mounted on stem 11 and normally retained in a closed position upon scat l5 by a spring member 17 which surrounds stem ll and has its opposed ends in abutment with the valve and the web 8. From the foregoing it will be apparent that the easing 5 is divided by the valve 16 into a pair of chambers 18 and 19. The chamber 18 communicates with a-suitable pipe or flexible hose through which liquid may flow from a tank into the chamber 18. 'The chamber 19 is provided with a suitable filling spout 20 for insertion into a container to be tilled and whichdirects the liquid which flows from chamber 18 through chamber 19 when the valve is raised from its seat.

In order to provide convenient means for handling the device and for actuating the valve, the casing 5 is provided with a prefchamber 19 and spout 20.

erably integral handle and actuating support structure which joins the casing at its one end at a point 2i adjacent the coupling end i of the device and which point is most remote from the filling spent 20. The handle and guard member 522 is suitably curvcd to lit the hand and is aniplv spaced from the side and top end ol the casing to permit free movement of the linger of an operator between the handle and casng. it its top the handle 22 is developed into a substantially straight portion which extends in spaced relation across the top of the casing, stem and packing gland. The remaining section ill of the handle and guard member connects the section 23 with the top portion of the casing adjacent the filling spent 20. From the foregoing, and by reterence to the drawings, it will be ap parent that the handle and guard member extends in substantially the same plane as the axis of the filling spout, thereby facilitating directional moven'ientand manipulation of the device. A pair of integral arms 25 and 26 extend in spaced relation to one another and from the top portion of the casing 5 to the handle and guard member. A bell crank lever having arms 27 and 28 is pivotally mounted between the arms 25 and 26 adjacent the handle member, 'llhe arm 28 lies immediately beneath the section 23 of the handle and guard member and is provided with a flat face 29 against which the end of the valve stem 12 abuts. The arm 27 of the bell crank lever is extended to provide an actuating lever 30. The spring 17 which normally retains the valve 16 upon its seat, also serves to normally retain the bell crank lever in the position shown.

When it is desired to use the filling nozzle the device is grasped in a natural manner with the handle 22 against the palm of the hand and the lingers between the lever 30 and the casing 5. The filling spout may then be conveniently inserted into the fillino opening of a. tanlc or container, after whic the lever 30 is moved toward the handle 22 by the fingers of the operator. This movement results in a downward movement of the arm 28, which depresses the valve stem against the resistance oi? the spring 17 and unseats the valve for permittin a flow or" fluid from the chamber 18, trough the lVhen it is desired to shut off the flow the pressure of Gin lOU

lltl

returns the lever to the position shown. It

will also be noted that the valve may be retained in a partially open position by imparting a slight movement to the lever. The

handle and guard portion 22, 23 and Q-l amply protect the actuating lever as well as the protruding portion of the valve stem against accidental operation, and also serves as a mounting means for the actuating bell crank lever,

What is claimed is:

1. In a device of the class described the combination of a valve casing, a valve controlling passage of liquid through the easing, a valve stem having an end projecting through the casing, a handle comprising a continuous member connected at itsopposite ends to opposite ends of the casing, and a bell crank lever pivotally mounted on the handle and. comprising a pair of arms, one arm lying between the handle member and the valve casing adapted to be actuated toward the said handle member for effecting depression of the valve stem by the other arm.

2. In a device of the class described the combination of a valve casing, a reciprocating valve stem extending through the easing and having one end projecting exterior-1y of the casing, a combined guard and handle member connected at its opposite ends to the casing and having its intermediate portion spaced from the casing and the projecting end of the stem, an actuating lever pivotally mounted on the intermediate portion of the handle lying between the said handle and the valve casing and movable in a plane therewith for depressing the valve stem when the lever is moved toward the handle, and resilient means normally retaining the stem in a projected position whereby the lever is yieldingly retained away from the handle. A

3. In a valve controlled filling nozzle the combination of a valve casing, a discharge spout and a rigid handle member disposed in a common plane on opposite sides of said casing, a valve in the casing controlling passage of liquid through the casing, and an actuating lever pivotally mounted on the handle member and lying intermediate the said handle member and valve casing for controlling the valve.

i. In a device of the class described the combination of a casing, a combined handle and protective guard member extending about one side and one end of the casing and connected to the casing at opposite ends thereof, a discharge spout extending angularly from the casing in a plane with the handle member and the casing, a reciprocating valve and stem therefor, one end of the stem projecting through the casing, actuating means pivotally mounted on the handle and guard member and comprising a bell crank lever having an arm normally abutting the end of the valve stem, and an actuating arm normally disposed adjacent the casing, the handle and actuating arm being adapted to be simultaneously grasped by the hand of an operator, whereby the operator may press the actuating armtoward the handle for depressing the valve stem, and resilient means for returning the actuating means and valve stem to their normal positions.

5. In a device of the class described the combination of a casing having an inlet port and a dischar e, spout, the dischargespout being intermeciate the ends of the casing and extending at an angle to the casin a valve intermediate the inlet port and discharge spout for controlling the flow through the casing, a valve stem extending beyond the easing, a combined protective guard and handle member having its ends secured to the casing and its body portion spaced from the casing, and a lever pivotally carried by the protective guard and handle member and disposed between the casing and body portioii'of the handle member for (lCPl'GcSlIlg the valve stem.

In testimony whereof, I have hereunto subscribed my name this 22nd day of November, 1926.

HARRY J. ERNST.
