Our invention relates to a uid dispensing system and more particularly to a gasoline dispensing system, for installation on and in a service station area wherein a service station includes a gasoline supply tank and a pump therefor to maintain air pressure in the system available for operating purposes in dispensing units located entirely below the surface of the ground.

Our invention is intended' primarily for use in a service area for vehicles, such as automobiles, trucks, aeroplanes, air ships, etc.

It is an object of this invention to provide an arrangement for dispensing equipment which can be eiiectively cleared from the surface of the service station area when not in use, thereby eliminating obstruction hazards.

Another object of the present invention is to provide a dispensing system which can be installed in a comparatively short-period of time by inexperienced help, if necessary.

A further object of this invention is to provide dispensing unit parts that may be lowered to a position below the level of the ground when not in use, thereby taking advantage of all of the space aiorded by surface area.

It is also an object of this invention to provide gasoline dispensing equipment located below the surface of the station area at suitable locations so that said equipment could be raised and lowered in a practical and convenient manner to provide service on the spot, i. e., any spot on the surface area of the service station.

An additional object of this invention is to provide a compact dual dispensing unit whereby, at least, two grades of gasoline products may be selectively dispensed.

A further object of our invention is to provide a central pumping unit in a service station house so that separate pumps and motors may be eliminated.I A pump and motor is required only for each grade of gasoline product and is capable of servicing e, plurality of dis-.- pensing units.

Stili another object of our invention is to provide an inexpensive built-in drainage system for each unit. This drainage system `is especially desirable in airport installations.

It is also an object of our invention to provide means for automatically eliminating the pressure on dispensing units when not in use, there by reducing fire hazards.

It is a further object of our invention to provide a pit casing having therein a hollow or cell body spaced from said casing by means of roller 11 Claims.

In the specification and the drawings thereof, the reference characters identify the particular parts of the system, including the details thereof.

The drawings are not to be considered definitive of our invention', but merely illustrative thereof, since many changes can be made within the scope of the invention, as claimed.

In our system, a plurality of pumping station the cell body is lowered into the pit units are contemplated, one of which is shown in the station house 53Figure 13.

Each pumping station unit is provided ywith a plurality of dispensing units connected directlyv 43 and a bottom closure 46, Figure 6, and a closure or floor at the bottom of the upper section 3. The fastening means passing through the ring anges 48 and the closures may be bolts, studs or rivets 43.

The pit casing l and the cell body or hollow body 2 are maintained in concentrically or equally spaced relation-by a multiplicity of roller bearings 'I retained in position on the wall of the pit casing I or on the adjacent wall of the body 2, preferably the former.

The concentric spacing constitutes a heat insulating feature which aids in preventing freezing while both the space and rollers 'I prevent jamming of the body 2 and the casing I The lower section 2' of the cell body 2 contains Self-retracting hose reels 4, positive piston disi placement meters Sand combination air releasers and strainers 6 in advance of the meters 5.

The pit casing I is provided adjacent its top portion with a laterally extending sectional and compartment box construction 9 and I0 receiving pipes or tubes 38, 33, 34, 35 and 36, including their valves which have operating means or handles 26, 2'I, 28 and 29. 'I'he operating 'means 26 is a foot pedal manipulated by the foot of the operator or attendant. The foot pedal 26 operates a three way air valve 25 for raising and lowering the cell body 2 within the casing I.

When the pipes andvalve are installed in compartment 9, as shown to the right of Figure 7, then the connectionsare made for the pipes and valves later to be housed in compartment I0. After the connections are made, the compartment I0 is inserted over the pipes from below. The use of the notches or recesses 50 in the ends of the compartment III makes the insertion assemblage possible.

The closure and retainer insert 43 is provided with notches or recesses 50' and 58" to receive the pipes 33 and 35. After the insert 48 is in asseming bolts through aligned apertures 52.

The raising and lowering mechanism or means I I is located between the bottom of the pit casing and the bottom 46 of the cell body 2. The means I I is operated by fluid pressure and said means I i is preferably telescopic and operates like a plurality of displaceable pistons. When the threeway air valve 25 is turned on by the foot manipulated pedal 28. the air under pressure enters the means II and raises the cell body 2 and its contents. When the air under pressure is released from this means II, the cell body 2 descends to its lowermost position. s

The gasoline hose I3 is supported von self-retracting reels, one of which is symbolically disclosed in the pit casing I to one side of the lifting or raising means II.

The self-retracting hose reels are supported on one side by a bracket I2 suspended from the bottom of the section 8.

The pipe or tube 33 conducts gasoline into one dispensing means through the hose I3 and finally to a nozzle 22. The pipe 33 is provided with a valve I5 having a valve head provided with a stem operated by a spring 8l. The transversely arranged iiat piece 83 is carried by the valve stem 85 and is adapted to be engaged by the cell body 2 when it is lowered. When the cell body 2 is in araised position, the spring 84 retracts the stem 85 and its valve head, thereby opening the valve. When the cell body is lowered, it closes the valve I5, whereby the iiow of gasoline to cell body 2 is stopped.

The metal ring 8 `which is substantially flush With the surface of the station area serves as a partial closure for the valve box 9.

The closure I6 of a dispensing unit may be fiat, but is preferably slightly convexed or domeshaped, as disclosed in Figures 1, 12, 17, 18 and 19. 'I'he closure I6 is secured by any suitable means to the upper edge portion of the cell body section 3. This closure is provided with a depending rim portion extending, at least, intoy close proximity to the ring 8. Between the rim and the section 3, the closure IE, Figure 12, is provided with an annular channel having a backing piece engaged by a yieldable ring 51 of rubber or rubber composition or any other suitable yieldable material. The ring 51 yieldably engages the upper edge of the pit casing I. This particular closure construction in connection with the air space between the body and the casing affords protection against freezing. The yieldable sealing ring 51 is secured in position against the backing of the annular channel by a pair of spaced concentric rings 58 and 58. 4

The upper section 3 of the cell body 2 is provided in its opposite sides with computers 28 having dials displayed through windows tted with flat panes of transparent material 42, preferably made of plastic. The other opposite sides of the section 3 are provided with display compartments having display windows containing convex panes 4 I, 4I of transparent material, pref-- erably plastic. In these compartments are convex frames II, I1 having floors or shelves for supporting, at least, some merchandise currently on sale at the service station house.

The frames I8 of the computer compartments are straight and extendaround the computers. The wall portion I9 is adapted to form a support for advertising material. The frames I8 contain a housing 39Figure 14, for a spring actuated electric switch. The terminal contacts 8| and 8B are secured to the inside o: the .housing as. 'me movable part l2 is moved to closed position by the spring 1l. The housing II contains a supi When the nozzle 22 is removed from its support the circuit, including the wires 'I6 and 1021s automatlcally closed by the switch. When the nozzle 22 is replaced on its support the switch is opened and the electric circuit is broken.

The antifriction bearings 2l, Figure 1, are adapted to engage the hose 9|, Figure 19, as it moves to and fro through the bearings 2l which are supported in the combined floor and shelf in the bottom of section 3. Y

In Figure 1, the shafts 23 connect the meters E with the computers 20. The quick releasable couplings 24, 24 connect the hose I3 with the combination air releasers and strainers B, 8. The swivel joints 3i connect the piping 32 with the hose 9i on the hose reels l.

In Figure 8, the pit casing l is provided with a drainage device comprising an eductor 56. Air is supplied through the pipe or tube 31 which passes through the aspirator 56 and draws the water, etc., from the casing i and forces it out through the pipe or tube 30. A hose (not shown) should be attached to the upper end of the pipe t@ to carry the drainage away to -a suitable place of disposal. When the drainage of the casing i is completed the valve 29 is closed and the hose may now be removed from the pipe 3U.

Air is supplied from the compressor in the service station house, which is also used for tire inflation as well as operating tools used in and about the station. A pressure relief valve is inserted in the discharge pipe line from the compressor to the telescopic pistons Ill. The function of the relief valve is to dissipate or discharge to the atmosphere any excessive pressure beyond a, predetermined setting of the relief valve. This arrangement is intended to prevent damage to a vehicle or to the unit, should a. unit be accidentally raised under a vehicle. The relief valve would insure just e. suiiicienfamount of pressure of air to cause the cell body 2 to rise. In the event of an abnormal weight on the closure I8, suchas a vehicle, the cell body 2 and its closure it could not rise. y

Control of the air for lifting and lowering the cell body 2 is maintained by the use of a threeway control valve 25. One side of the valve has the air inlet pipe Ik and the bottom has the air outlet and air return pipe 36 and the exhaust outlet pipe 35 is located on a side of the valve 25 opposite to the inlet pipe. The three-way valve it is located in the valve box 9 below the surface of the ground. Attached to the three-way valve 2d is a foot pedal 26; Figures 1, 10 and 11. To provide for operation of the control valve 25 by the cperatorsfoot, the foot pedal 2E is connected to the circular part 55 of the valve 25 by means of an extensible arm 53 including a spring 5i to maintain the arm' 53 normally in retracted condition with the foot piecev located in one of the recesses d or El. The recesses 5l and 5|' are large enough to receive the toe of the operator's boot or shoe, so that the foot piece can be lifted and tilted to a desired position.

In Figure 13, the station house 59 is provided with agasoline storage tank 65 located below the .'ieveliof the service station area. The tank 65 6 is provided with a nlling tube or pipe t! and a vent pipe il having a. vacuum relief valve il. a flame arrester il and a detachable pipe connection or union I3.

The mechanism located in the station house 69 is provided with a supply pipe 33 for dispens ing units located in the service station area. The pipe ,13 is connected by a unison il' with the gasoline discharge line or tube 1l. The discharge tube 'll is provided with a pressure gage I6, a thermometer 61, and a register l! for gallons of gasoline dispensed from the storage tank il. The pipe il is connected to the tank tube by a coupling or union 83" and is provided with a. check valve 10 adjacent to its connection with the pipe or tube 1l. Both the check valve 10 and the pipe 18 are connected by pipes or tubes having an interposed pressure relief valve 1I. The pump Il has a pipe or tubular connection 11 which is provided with a strainer l2 interposed therein.

The pump 'i3 is operated by the explosion proof motor 'Il which is provided with a controlling means 15. The electrical conductors 'I6 lead to the various dispensing units located in the service station area.

The markers 88 are placed about the dispensing units to aid drivers of vehicles in properly placing `their vehicles in a suitable position for convenient servicing from a dispensing unit. The marker includes a spike or prong having a head with an upright wall 8B surrounding a reflecting jewel 81.
