The drawing shows a key switch billing system 6 according to an embodiment of the invention when it is used in a liquid dispensing pump 8 for billing the amount of liquid dispensed to each of several authorized persons.In a conventional manner, the fuel dispensing pump 8 has a feed pump 10 driven by a motor 12 for delivery of fuel via a measuring mechanism 14 and a shut-off valve 16 to a fuel dispensing nozzle 18. The fuel pump also has a resettable register 20 with a volume counter 22 and a cost counter 2h, each with a visual display, for the visible registration of the volume and the cost of the fuel quantities supplied. The output shaft Z6 of the measuring mechanism 14 rotates proportionally to the fuel volume dispensed and drives that

209850/0118

Volume counter 22 and the accounting counter 24 of the Register 20 to · For the adjustable selection of the price per unit volume of the fuel dispensed a variator 28 connected between the measuring mechanism 14 and the cost counter 24 in a known manner Register 20 may be used, for example, from that described in U.S. Patent No. 2,932,448 issued April 12, 1960 Type and has a suitable reset mechanism, to zero the volume counter and the cost counter 22 or «24 before the start of each liquid dispensing process is actuatable.

The fuel nozzle 18 has, as shown, in a conventional manner a hanging box 30 for accommodating the dispensing nozzle between the dispensing operations (viewed from the right in Fig. 1) must be rotated to its vertical off position to allow the nozzle to be re-hung in its hanging box, and that the nozzle must be removed from the hanging box to pivot the control handle 32 about 99 in. in the opposite direction to its horizontal on position. The control handle '32 is connected to the register 20 via a control shaft 34 in such a way that when the control lever 32 is in

209850/0118

its Einsehaltstellung is pivoted, the fuel pump 8 is activated for the delivery of fuel by switching on the engine 12 and the Valve 16 is opened. When the control handle 32 is pivoted into its vertical switch-off position, the motor 12 is switched off and the valve 16 is closed, to shut down the fuel pump 8 for the delivery of fuel «.

The key switch accounting system 6 is provided for accounting for each fuel dispensing process with the relevant customer or user. The system 6 has a pressure device 52 and a lock $ h which can be actuated by means of a plurality of keys (as part of a key switch $ 6) , which allows the pump 8 to be optionally blocked or unblocked for the delivery of fuel. The key switch 56 contains a key identification register 57 (with a plurality of pressure rollers 58-64 with increasing value) which forms a key identification part of the printing device 52. The printing device 52 also has a fuel dispensing part 66 which is formed by a printing counter 68 (with a plurality of printing counting rollers 70-73 with increasing digit values) for printing out the amount of fuel dispensed. In the illustrated embodiment

209850/0118

the printing counter 68 connected so that it can be driven jointly with the volume counter 22 and counts the volume of the amount of fuel dispensed. Instead, the printing counter 68 could be connected in such a way that it reduces the cost of the fuel dispensed quantity (or an additional printing counter (not shown) could be used for this purpose can be used) · The printing counter 68 is preferably resettable and is (with the volume counter together) immediately before the start of each fuel dispensing process and automatically reset immediately before the pump 8 is ready for fuel delivery,

68
If the printing counter could not be reset, of course, the amount dispensed with each individual dispensing process could be determined by determining the difference between

the counter readings are determined before and after the dispensing process «

The counter 52 has a suitable printing unit 76 (shown schematically in FIG. 1), which can be actuated in such a way that it outputs a document corresponding to the registration of the fuel delivery by the pressure rollers 70-73 and the key identification pressure rollers 58-64 at a reading point or station 78 supplies. The printing unit 76 is expediently connected to the pump control shaft jh , so that in each case a document before the beginning and / or after the end

209850/01 18

every fuel dispense is delivered when the control handle 32 in its on position and / or off position is swiveled · If, for example, the printing counter 68 is zeroed, it is sufficient after the completion of each dispensing process (and before the zeroing of the printing counter 68) to print out a single receipt instead of this, if the printing counter 68 cannot be reset, It may be desirable to provide a receipt both before the start and after the end of each dispensing process (for the determination of the amount of fuel dispensed with each dispensing process, if, for example, a ticket with the printed information is issued to the user of the pump) or immediately before or immediately after each dispensing process (if the printed information is only retained for our own purposes are) to make available or · to print out «For example, successive documents be printed out on a continuous strip of paper, which remains inside the pump 8 and later for the Offsetting the amounts for the individual dispensing operations with the individual authorized users is taken.

The lock $ k of the key switch is a cylinder lock which, in a conventional manner, has a lock housing 79 and a cylinder 80 rotatably mounted in the lock housing, which (between a first normal locking

Each pressure roller adjusting means 84 is locked to an associated pressure roller 58-64 in such a way that it can move it into either of two operative positions. For each pressure roller 58-64 a leaf spring holding arm 96 is also provided for precisely aligning the pressure roller in each of its two operating positions. Thus, when the roller actuator 84 is in its normal locked position, the associated pressure roller 58-64 is held in a first or normal position, and when the roller actuator 84 is rotated with the cylinder 80 (when the cylinder is to make the pump ready for fuel delivery is rotated), the relevant pressure roller 58-64 is rotated into a second extended position.

The pressure rollers 58-64 are preferably numeric Letters or print types of the numbers 1 to 7, and there is only a single type element on each print roller, which is arranged to provide a print in the printout or reading station 78 when the pressure roller is in its extended position So Venn locked the lock 54 in his State, all pressure rollers at the printing station 78 have blank spaces, and with a key identification printing mechanism With seven rolls, the following separate numerical information or key IDs can be printed out:
