Application filed duly l3,

This invention relates to gasoline dispens ing systems and has for its object the provision of a device to which may be connected a plurality oi vending stands at a filling station and in which any one of the vending stands maybe operated for dispensing; gasoline independently of the other stands.

Anoth r object oi? the invention is the provision of a gasoline dispensing system having a single auxiliary tank to which connected a plurality oi vending devices whereby any one of the vending devices may be operated independently oi the other devices by cutting oil the air pressure between the auxiliary tank and the source or? air.

A further object of the invention is the provision of a gasoline dispensing system in which an automatic selective valve which is operated by compressed air to cut oil the r mainder of a plurality of vending; devices when one vending device is in operatio..., employed.

This invention will be best understood from a consideration of the following do tailed description, in view of the accompanying drawings forming a part of the speciiication; nevertheless it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications which shall define no material departure from the salient features of the invention as expressed in the appended claim.

In the drawings: Figure 1 shows diagrammatically a dis-- pensing system constructed in accordance with the principles of my invention.

Figure 2 is a vertical longitudinal section of a selectivevalve for automatically controlling the compressed air in the system.

Figure 3 is a bottom plan view of the same.

Referring more particularly to the draw ing, 1 designates a main supply tank which is connected through a conduit 2 with an. auxiliary supply tank 3. A. check valve iis located within the pipe 2 which will permit gasoline from the main tank 1 to flow to the auxiliary tank 3 but which will prevent the return of the gasoline from the auxiliary to the main tank. These tanks are buried in the ground and a vent pipe connects the main tank 1 with the atmosphere.

A dispensing pipe 6 having its lower end located in the auxiliary tank 3 is provided with a foot valve 7 oi the usual type. The

1925. Serial lilo. lhfitlfi.

pipe 6 has a branch pipe 8 which opens into a dispensing tank 9 located above the surface of the ground to which is connected a discharge pipe 10 with a valve 11 located in said pipe for controlling the dispensing of the gasoline from the container 9. This container is connected adjacent its upper end with the main tank l by means of an overflow pipe 12.

Pneumatic pressure is maintained in the main tank and the auxiliary tank respectlvely by pipes 13 and let. An air supply pipe liilis connected to the pipe 13 by means of a branch pipe 16 and a. two-way valve v 17. A branch pipe 18 connects the pipe 14lwith the valve 17. An automatic selective valve 19 is placed in the branch pipe 18 and apipe 20 is connected between said valve and a two-wayvalve 521 which is operated by a lever by -pass 23 connects the pipe 15 with the two-way valve 21. i

A conduit places a stand pipe 8, which has its lower end the auxiliary tank 3, in communication with an overhead container 25 in which the gasoline from said auxiliary tent: is orccd and tempo rily stored before is di iensed through use tub 538 when the valve 5.? open. A valve 28 in the pipe 524 closes communication between the container 535 and pipe t" and is operated through a lever Q9 which simultaneously operates valve 21 through a link 30. lln a similar manner a valve 31 in pipe 8 is operated by a lever 32 which simultaneousl rocks lever 33 connected. with valve 1?. link 34 connects levers 3t? and 33.

Any number of automatic selective valves may be placed in the pipe 18 as shown at 19 by means of a conduit 35 connected to another dispensing; container similar to the container 25 and all operated from the same system.

As shown more particularly in Figures 5?; and 3 the automatic selective valve comprises a casing 36 having its opposite ends threaded as shown at 3? and 38 for mounting the same in a pipe line. The casing is provided with an internal chamber .39 in which is loosely mounted a ball valve 40. This valve is adapted to engage a seat 41 or a seat 42 threaded into the opposite end of the casing 36. The casing has 8. depending nipple 43 adapted to be threaded on a section of the pipe 18 leading to the auxiliar tank 3 and slots it are provided in the we 1 of the casing; for placing the chamber 39 in till) till Elli) ltlb communication with the hollow nipple 43. The valve seat 42 is removable and is provided witha slot 45 adapted to be engaged by a suitable tool for turning whereby the seat may be removed or replaced. The removable seat 4&2 permits the removal or insertion of the bail valve 40.

The operation of my device is as follows:

The air valves 17 and 21 are normally maintained open to the atmosphcreso that after a certain. quantity of gasoline has been dispensed from the device the pressure may be relieved. The pipe isconnected to the valves 17' and 21 so that when either oi? the valves 17 or 21 is closed air pressure will be exerted on the auxiliary tank- 3 and force gasoline up into the dispensing container 9 or 25 as the case may be and which depends upon the operation oi either of the valves. en it is desired to dispense gasoline from the dipensing container 9 the lever 32 is moved to a vertical position whence valve 31 places the container 9 in communication with branch pipe 8 and stand pipe 6 and valve 17 closes the exhaust pipe 16 which is connected to pipe 13 and in turn to the top of the main tank 1 whence pipe 15 which carries the source of compressed air will, through pipe 18, be connected with the automatic selective valve 19. The ball valve 40 is then forced upon its right hand seat cutting ofi pipe and where there are other dispensing devices the ball 40 as shown in the selective valve 19' is likewise moved to close ipe 35 so that the compressedair is cut 02 automatically from the other dispensing devices to prevent the escape of air through such manually operated valves as 21. The compressed air through pipe 14 acts on the li uid in the auxiliary tank 3 and said liqui is forced upwardly through pipe 6 to branch pipe 8 past open valve 31 and into the container 9 whence it may be dispensed by opening valve 11.

After the filling of the container 9 the valve 31. is closed by moving the lever '32 to the position shown in Figure 1 and simultaneously valve 17 is positioned to open the fill exhaust through pipe 16 to the atmosphere. If it be desired to dispense gasoline from the container it is only necessary to move lever 29 towards the right until the valve 28 places the container 25 in communication with pipe 24 and likewise through pipe 6 placing the pipe 24 in communication with the auxiliary tank 3. By the simultaneous movements of valves 21 and 28 valve 21 closes the exhaust pipe 13 to the atmosphere so that the air pressure from pipe 15 Will be transmitted to pipe 20 against the ball valve 40 in the valve 19 forcing the valve to the left and closing the pipe 18 to the action of the compressed air. The com-- pressed air then acts through pipe 1 1- on the top of the liquid in the auxiliary tank 3 and supply tank 3 as may be since the valve 31 is closed and the Valve 28 is open gasoline will be forced into the container 25 whence it may be dispensed by manipulating the valve 27. lVhen all the gasoline is dispensed that is necessary the lever 29 is then moved to the position shown in Figure 1. In practice the container is filled and the valve 31 is shut off at once, the gasoline being dispensed from the container either immediately or at a later time.

As shown by the automatic selective valve 19 pipe 13 is adapted to be connected with a third dispensing container. and as many dispensing devices may be employed and placed in. communication with the single auxiliary desired so that it is only necessary to employ a single auxiliary container at a station in order to dis pense liquids from said container through a plurality of dispensing devices.

In the position of the dispensing apparatus shown in Figure 1, valves 17 and 21 are normally open to the atmosphere so that compressed air may exhaust from pipes and permit gasoline from the main tank 1 to flow to the auxiliary tank 3. When the valves 31 and 17 have been manipulated in order to place pipe 8 in communication with pipe 6 air pressure in pipe 18 will act on the ball valves 40 in the automatic selective valves 19 and 19 and-maintain the pipes 20 and closed. When valve 28 has been opened valve 21 will permit air pressure from pipe 23 to act through pipe 20 on the ball valve and force it in the opposite direction so that air pressure will act upon the fluidin tank 3 and force gasoline into the container 25 whence it may be dispensed. The combined valves of other dispensing devices may be similarly operated and a similar automatic selective valve such as 19 or 19 may be employed to automatically shut off the air to the other dispensing devices.

An overflow pipe 12" is connected between container 25 and overflow pipe 12 to relieve excess liquid from said container during It will be appreciated that valves 28 and 31 do not act to cut off the flow of the gasoline from the auxiliary tank 3 respectively to the dispensing containers 9 and 25, but acts rat-her when closed to retain the liquid in the containers since the flow of the gasoline is controlled through the manipulation of the air valves 17 and 12 and the consequent actuation of the ball valve 40 through air pressure.

at I claim is:

In a liquid dispensing apparatus, a supply tank, an auxiliary tank from which liquid may gravitate from the supply tank, a plurality of elevated liquid dispensing containers, a source of compressed air, a discharge pipe leading from the auxiliary tank,

' trol valve in each branch pipe for preventing the return ofliquid from a dispensing container to the auxiliary tank, an air pipe connectedwith the auxihary tank, a pair of pipes connected with the compressed air supply and having a common pipe forming a connection with the air pipe in communication with the auxiliary tank, a double acting valve in the common connection to close either of the pair of air pipes to the air pipe connected with the auxiliary tank, a manually controlled valve in each of the pipes connected with the source of compressed air, and means connecting the air valve with a liquid control valve whereby both valves may be operated simultaneously for opening the air pipe'to the atmosphere and for closing'the branch pipe to the auxiliary tank, the arrangement being such that when an air valve is open to the atmosphere and the coordinated liquid control valve is closed, the double acting valve in the common connection will be moved to close the last mentioned air pipe when the other air valve places its respective air pipe in communication with the compressed air supply and the liquid control valve associated therewith isopened.
