724,064. Filling receptacles. AVERY-HARDOLL, Ltd. Dec. 12, 1952 [April 18, 1952 ; July' 11, 1952; Aug. 6, 1952], No. 31590/52. Class 21. [Also in.Groups XVIII and XXIX] A receptacle filling device is provided with automatic means for stopping the filling including a main valve closed upon the attainment of a pre-determined level of liquid in the receptacle and a jet nozzle through which at least a part of the liquid flows in the form of a jet to impinge upon a pilot tube type of pressure intake and means effective upon the filling of the receptacle to the required level to disturb the jet and thereby reduce the pressure in the pressure intake and means associated with the main valve on which the pressure obtaining in the pressure intake acts to maintain the main valve open so long as the jet remains undisturbed. The hosecock shown in Fig. 1 comprises a main duct 1, a main valve 2, an auxiliary valve 3 normally closed by a spring 4, an operator's grip 5 controlling a rod 7 moving in the bore of a piston 9 fast with the main valve 2, a push rod 6, and a pin 8 fast with the piston 9 and extending through a slot 7a in the rod 7 so that the rod 7 can move the push rod 6 without moving the piston. A spring 10 is disposed between the push rod 6 and the auxiliary valve 3. A branch 11 connects-those parts of the duct 1 situated upstream and downstream of the valve 2 and a jet nozzle 12 with an associated pressure intake 13 receiving the jet are located in the branch 11. An annular groove 14 runs from the pressure intake 13 to a duct 15 opening in to a chamber 9e under the face 9d of the piston 9. An orifice 17 at the downstream end of the duct 1 communicates via a tube 19 to an orifice 18 located downstream of the jet 12. In operation the nozzle is inserted into the tank until the orifice 17 is at the level to which the tank is to be filled. The operator moves the lever 5 against the spring 16 whereby the pushrod 6 is forced back and compresses the spring 10 by the movement of the rod 7, the piston 9 remaining stationary. The valve 3 under the pressure of the liquid supply and of the spring 10 opens against the action of the spring 4 and the liquid flows through the branch 11 to the jet nozzle 12. A substantially cylindrical jet impinges on the pressure intake 13 and draws in air from the tank via orifices 17 and 18. The pressure created in the intake 13 is transmitted to the face 9d of the piston 9 and is sufficient to move the piston 9 and the valve 2 against the liquid pressures acting on the upstream side of the valve 2 and on the face 9c of the piston. When the liquid reaches the orifice 17 no further air passes through the orifice 18, the jet from the nozzle 12 loses velocity and the pressure in the pressure intake falls. The piston thereupon moves downwardly under the liquid pressures and closes the valve 2. Valve 3 then closes. The operator may at any time stop delivery by releasing the handle 5 whereupon the rod 7 is retracted and pin 8 on its downward movement withdraws the piston 9. In another embodiment the push rod 6 is replaced by a further auxiliary valve which controls a flow of liquid to the face 9d of the piston and opens the valve 2 before.the valve 3. As soon as the valve 3 is open the auxiliary valve closes and leaves the piston 9 open solely under the controlling pressure of the intake 13. In a further embodiment, the valve 3 is omitted, the supply to the branch 11 being controlled by the valve 2, and the lever 5 is replaced by a push-button. In another embodiment the pressure set up in the intake is transmitted to a flexible diaphragm operating a system of levers which maintains the handle 5 and hence the valve 2 in an open position until the pressure drops at the intake 13. In a further embodiment two nozzle and pressure intake systems are provided the first serving to diminish the flow as the required liquid level is approached and the second, which only then becomes operative, to shut off the flow when the level is finally attained.
