BRIEF DESCRIPTION OF THE DRAWING The drawing shows a schematic representation partly broken away of a fuel dispensing system incorporating an embodiment of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawing, a self-service fuel dispensing system incorporating an embodiment of the present invention is shown including a fuel pump 10 having the usual nozzle 14 for delivering fuel and Va suitable storage receptacle 1S for storing the nozzle 14 between deliveries. A meter 16 in the fuel line provides in a conventional manner for driving a register 18 for registering the volume and cost of fuel delivered, and an electric motor 20l is employed for operating a suitable reset mechanism 21 for resetting the register.

The pump 10 is adapted to be activated for delivering fuel by energizing a motor 22 for the fluid pump 23 and by energizing a pair of solenoid operated valves 24, 26 mounted in series in the fuel line to control the delivery of fuel. The valve 24 has open and closed positions and the valve 26 has open and throttled vpositions so that by de-energizing the valve 26 the rate of fuel delivery is adapted to be reduced or throttled and by subsequently de-energizing the valve 24 the fuel delivery is adapted to be terminated.

The disclosed system includes a selector switch 30 which is key operated to select Attended (A) and Unattended (U) poistions. With the selector switch 30 in its Unattended position, a Reset switch 32 located at or adjacent the pump 10 (or an alternative Reset switch 34 located remotely from the pump 1()` as for example at a kiosk which is manned for Attended operation) may be manually actuated to energize the reset motor 20 to reset the register 18, and at the end of the reset cycle the reset mechanism 21 actuates an acceptor control relay 35 to its on position to energize a money acceptor 36. The money acceptor 36 which is preferably located at the usual pump island is adapted to provide for activating the pump 10 for delivering fuel after a predetermined deposit is collected by the acceptor. For example, the money acceptor 36 -may be designed for collecting one dollar in coins or a single one-dollar bill before that amount is collected and a fuel delivery in that amount can be made.

The money acceptor 36 is connected (when the selector switch 30 is in the Unattended position) via the selector relay 40 to actuate a pair of control relays 44, 46 to their on positions and to thereby energize the pump motor 22 and the solenoid operated fuel valves 24, 26. At the same time, the acceptor control relay 35 is actuated to its off position to de-energize the money acceptor 36 and to thereby discontinue the operation of the acceptor 36 until the end of the succeeding reset cycle of the register 118. Also, a reset control relay 48 is actuated while the motor 22 and valve 24 are energized to prevent operation of the `reset motor 20 during the delivery of fuel. However, if desired, a suitable manually operable Stop switch 0 provided at the pump may be operated (or an alternative Stop switch 52 at the kiosk may be operated) as for example if it is desired to terminate the fuel delivery before the amount of fuel paid for has been delivered. Also, the Stop switch 52 could be operable by a suitable timer (not shown) to deactivate the pump after a given time interval and an additional Stop switch 53 is mounted on the pump adjacent the nozzle storage receptacle 1-5 to automatically deactivate the pump when the dispensing nozzle 14 is returned to its storage receptacle.

A predeterminer 58 is employed in the system for automatically actuating the control relays 44, 46 to their off position and for thereby timely dicontinuing the delivery of fuel when the amount of fuel paid for has been delivered. The shown predeterminer 58 comprises a pair of predetermining counters 6I), 61 and a third money counter 62, each of which preferably comprises .a bank of conventional single wheel magnetic counters 64 of the type which are adapted to be electrically reset and which have readout sections which may be used as predeterminers for automatically deactivating the pump 10 when the amount of fuel paid for has been delivered.

The counter 62 provides for registering the amount of money deposited in the acceptor 36 and is accordingly connected to be appropriately indexed by the money acceptor each time the predetermined deposit is collected by the acceptor. Thus, with the system in its Unattended condition, the counter 62 is indexed to register the predetermined deposit, for example one dollar, at the same time the control relays 44, 46 are actuated to energize the motor 22 and valves 24, 26. Therefore, if for example the money acceptor 36 is designed to collect one dollar, the third or hundredths order single Wheel counter 64 of the counter 62 will be indexed one step to provide a registration of 100, in which instance the two lower order single wheel counters 64 play no active part and can therefore be deleted if desired.

The counter 61 is provided for manually setting the monetary amount of the delivery when the kiosk is attended, and for this reason its single wheel counters are shown having suitable manually operable push buttons 66 for setting the single wheel counters. The counters 61 and 62 do not, however, perform any function when the selector switch 30 is in its Unattended position and the kiosk is unmanned. The counters 61 and 62 are, however, adapted to be reset with the counter 60` at the same time the reset motor is energized to reset the register 18. In this regard the counters 60 and 62 are adding counters (i.e. adapted to be indexed in the adding direction) and are therefore reset to zero (000); whereas the counter 61 is preferably a subtracting counter (i.e. adapted to be indexed in the subtracting direction) and is therefore reset to its maximum count of 999.

. The counter 60 is used during Unattended operation to automatically discontinue the fuel delivery after the amount of fuel paid .for has been delivered. Since, the-refore, the deposit which may be collected by the acceptor 36 is predetermined, the counter 60 is connected so as to deactivate the pump after that amount of fuel has been delivered. In the present embodiment the counter 60 in indexed in the `adding direction during the delivery of fuel and for example if the predetermined deposit is one dollar, the counter 60 will provide for discontinuing the delivery as it is indexed to 100. l

A pulse generator 68 driven by the cost counter 70 of the register 18 is connected to index the counter 60 in accordance with the amount of fuel delivered. Thus, if the predetermined deposit is one dollar, the pulse generator 68 will provide for indexing the counter 60' from 000 to 100 at which point the delivery of fuel will be terminated. For this purpose, the readout sections of the single wheel counters 64 of the counter 60 are connected so as to provide a first signal at` 080 to actuate the control relay 44 via the selector relay 72 and to thereby de-energize the valve 26 to reduce the rate of fuel flow and a second signal at 100 to actuate the control relay 46 via the selector relay 73 and to there by de-energize the motor 22 and valve 24 to terminate the delivery of fuel. Also, with conventional single wheel counters 64 designed to be indexed at the end of the pulse generated by the pulse generator 68, the pulse generator 68 is mounted so that the generated pulse ends at approximately when the amount delivered corresponds with the succeeding reading of the register.

The system may be switched to the Attended condition with the selector switch 30 to provide for attended self-service operation. In its Attended position the selectorswitch 30 provides for actuating the selector relays 40, 71, 72, 73, 74 to provide for (l) connecting the control relays 44, 46 for actuation to their on positions by a manually operable Start switch 90 instead of the acceptor 36 to their off positions by the predetermining counter 61 instead of the predetermining counter 60; (2) connecting the pulse generator 68 for indexing the counter 61 as well as the counter 60; and (3) disconnecting the Reset switch 32. The acceptor 36 may, however, be used during Attended operation, and the counter 62 will be indexed when the predetermined deposit is collected by the acceptor. And since the acceptor 36 is not de-energized until the Start button 90 is depressed, the counter 62 will be indexed each time the predetermined deposit is collected by the acceptor 36, and the counter 62 will indicate the total deposit collected by the acceptor. After such deposit, or if the money acceptor 36 is not used, as for example because the fuel is paid for directly to the attendant either before or after the delivery, the monetary amount of fuel to be delivered is manually set into the counter 61 :by manual actuation of the counter push buttons 66. For this purpose, an intercom system with a speaker 84 at the pump and a speaker 85 at the kiosk is shown provided for assisting the customer in informing the Aattendant of the amount of fuel which he wishes to have if he does not use the money acceptor 36.

Thereafter the Start switch is actuated by the attendant in the kiosk for activating the fuel pump 10 to enable the customer to deliver the desired amount of fuel. The pulse generator 68 will index the counter 61 in the substracting direction during the delivery. of fuel and when the preselected amount of fuel is delivered the pump 10 is deactivated to terminate the delivery of fuel. As with the counter 60, the'counter 61 provides a first signal, as for example at 020, to actuate the control relay 44 for de-energizing the valve 26 and for thereby reducing the rate of flow of fuel and .a second signal at 000 to actuate the control relay 46 to terminate the fuel delivery. And if the amount of fuel originally preset in the counter 61 is not delivered, as for example due to the customers tank being full, the pump is adapted to be manually deactivated by the Stop switch 50 or Stop, switch 52 or to be automatically deactivated by the switch 53 when the nozzle isreplaced in its storage receptacle 15. The attendant can then determine the refund due or amount owed,vas the case may be, directly from the counter 61 for a refund or directly from the counter 60 for determining thecost of the fuel de livered. v y

A nonpredetermined delivery may be made by the attendant in a conventional manner vmerely by placing the selector switch 30 in its Attended position in'.which case a maximum of $9.99 worth of fuel may bedelivered before the pump is deactivated. Additionally the counter 61 may be appropriately disconnected as with the switch 80 if for example -a greater amount of fuel is to be delivered. The switch 80 is also shown adapted for connecting the Reset switch 32 directly to the reset control relay 48 and for thereby bypassing theselector relay 74 sothat the operation ofthe pump will then be controllable Iwith the manually operable reset switch 32 and the manually operable. Stop switch 50 or switch 53. And the attendant may then resetthe pump register 18 with the Reset switch 32, deliver-the amountiof fuel desired and after the completion of the delivery deactivate the pump with the switch;50 or switch 53.

A pump selector switch 90 forI the acceptor 36 is shown provided for selectively employing the acceptor 36 inthe self-service systems of two or more pumps. Thus, a customer may manually operate the pump selector switch90 toselect a given pump, as for example to select a particular grade of fuel, and then place the'predetermined deposit in the'acceptor 36 upon which occurrence the selected pump 10 will be conditioned `for delivering fuel as previously described. A succeeding cus tomer may then select and activate another pump (not shown) in the same way without having to wait for the completion of the delivery of the preceding customer.

As will be apparent to persons skilled in the art, various modifications and adaptations of the structure above described will become readily apparent without departure from the spirit and scope of the invention.
