v INVENToR w.D.coQK Q Feb. 8p 1944. w; D. cooK l FILLING DEVICE Filed April '7, 1941 Patented Feb. 8, 1944 Fiume DEVICE William D. Cook, Detroit, Mich., assignor to Phillips Petroleum Company, a corporation oi' Delaware ApplicationApril 7, 1941, Serial No. 387,293

(ci. 22o-s6) 3 Claims.

This invention relates to a filling device for use with containers'to prevent overfilling the container. Y

In the handling of liqueiied gases and volatile liquids, the containers in which the liquefied gas is transported or stored must not be filled above limits prescribed by law. Because of the high volatility and infiammability of liquefied petroleum gases, such as propane, butane, and mixtures containing one or both of them, many of the liquid level gauges applicable to use with less volatile or less inflammable liquids are not advantageously used with liquefied petroleum gases. On some of the larger storage containers and transport tanks, a clip tube gauge is used. These devices are well known and consist of a small tube extending into the container with a valve on the portion of the tube outside the container. The end of the tube inside the container is set at a predeterimned point relative to the top of the container or, in some gauges, may be varied at will during the gauging operation. The operator may determine whether the open end of the dip tube inside the tank is above or below the surface of the liquid by opening the valve and noting' whether vapor or liquid is expelled. Portable containers often are not equipped with a liquid level device. These containers are lled to the proper extent by weighing or metering the liquefied gas into the container. f

The present invention provides an improved filling device for use with the containers by which e the containers may be filled to the desired extent without the necessity or gauging the liquid. The device is attached to the container inlet and automatically retards flow of liquid into the container when a predetermined liquid .level is reached.

An object of this invention is to provide an improved filling device for use with containers.

A further object of this invention is to provide a device which will automatically retard flow of uuid into a container when a predetermined level has been reached.

- The drawing is an elevational view in vertical cross-section oi' a container showing the device of the present invention in position.

With reference to the drawing. the numeral l designates the container with which the lling device 8 is to be used. The lining device extends through the top oi' the container and is attached thereto by any suitable means, as bywelding to the plug l in the top of the container. Attached to the iilling device, outside the container. is the valve 8 which is normally closed except when the container is being filled. 'I'he body of the filling device comprises an enlarged portion 9 containing.

vice and is normally maintained in a vertical position, as illustrated in the drawing, by the counterweight I4. The counterweight is joined to the valve disk by the lever arm I5 which passes through a slot I6 in the iilling device;- 'I'he slot is of suicient size to allow freedom of movement of the valve disk from the vertical position to the horizontal position C indicated by dotted lines in the drawing. When the valve disk I0 is in the horizontal position C the resilient valve face II cooperates with the valve seat I2 to prevent ilow through the conduit II into the container. Directly opposite the counterweight I4 is a port I8 through which liquid from the conduit I I may fiow into the container.

The operation of the device is as follows. Liquid from an external source is admitted to the container through the valve 8 and flows through the filling device into the container 6. In flowing' through the conduit II of the filling device liquid mayalso be diverted through the port I8 into the container. The iiow rate through the valve 8 is so adiusted that very little. if any, liquid is diverted through the port I8 during the iilling operation. When the liquid in the tank reaches the predetermined level L in the container the flow ot liquid through conduit I I is opposed-by the liquid in the tank. liquid passing through the con duit Il is discharged against the liquid head equal to the depth of submergence of the lower end of the conduit II below the liquid level L. This added resistance to ilow of liquid through the conduit II causes an increased volume ot liquid flow through the port I8. Liquid discharged through the port I8 impinges on the lever arm and counterweight I4 swinging it away from the conduit II to some intermediate position B.

- Motion of the lever arm I5 moves the valve disk I8 a corresponding amount into its intermediate position B. When the valvedisk l0 reaches the intermediate position, liquid flowing through the filling device exerts ,a torce on the upper side ofl the disk moving it into closed position C. Interruption of flow of liquid through the conduit II may be detected by the operator lling the containedby any suitable means. The 'operator may then close the valve 8 and proceed with iilling of other containers. l

It is to be noted that the device of the present I invention eliminates the necessity for a liquid level gauge. The present illling device interrupts the'riow of liquid to the container when the deaired liquid level has been reached. The operator illling the containers is thereby relieved of the responsibility of constant vigilance to prevent a filling device comprising a body member. a

conduit extending from the body member into the container, the lower end of the conduit being submerged in the liquid in the container when the container has been nlled to the proper height, a valve in the body member to close the conduit connected to the body member, a port through the wall of the conduit through whichthe iluid entering the conduit flows into the container when the lower end of the conduit becomes submerged, and means connected to thev valve and actuated by the flow of uid through the port to close the valve and prevent further liquid entering into the container.

2. In combination with a container for liquids, a illling device comprising a body member, a conduit extending from -the body member into the container, the lower end ofthe conduit being submerged in the liquid in the container when the container has been illled to the proper height,

and prevent further liquid entering into the container;

3. In combination with a container for liquids, a filling device comprislnga body member, a conduit extending from the body member into the.

container, the lower end` oi the conduit being submerged in the liquid in the container when the container has been filled to the proper height, a valve disk plvoted in said body member and normally positioned out of the path of fluid now entering the container but adapted to close the conduit connected to the body member, a weighted lever arm attached to said valve disk which maintains the valve disk normally out of the path of il'uid flow through the body member, a port through the wall of the conduit intermediate its ends through which the fluid entering lthe chamber ows into the container when the lower end of the conduit becomes submerged, and the fluid ilow through the port actuating the weighted lever arm to pivot the valve disk to a closed position on the conduit and prevent further liquid entering into the container.
