INVENTOR SAN/Mn Velma/m;

ATTORNEYS FUEL SUPPLY CONTROLLING APPARATUS This invention relates to a fuel supply controlling apparatus and more particularly to an apparatus for controlling fuel supply systems adapted for the sale of fuel on the credit basis, the self-service of fuel supply and other sales and other sales systems for supplying fuel to specified customers.

In the usual gasoline station for supplying fuel to vehicles of specified customers on credit sale, generally the operator records the amount of supplied fuel on the sales bill each time of supply of fuel and the customer puts his signature on the sales bill for acknowledgement. Then the sales bills are summed up periodically on a monthly basis for subsequent collection of money for the supplied fuel from customers. Registering of supplied fuel amount in the bills, periodical summation of collected money and other sales businesses become complicated accompanying labor as the number of customers increases and often there arises the possibility of errors in writing credit code or vehicle numbers on the sales bills.

Major transportation companies using automobiles such as bus and taxi companies have their own fuel-supplying apparatus within the enclosure of their firms whereat the drivers can desirably supply fuel to their vehicles by themselves when it is needed and register the fuel amount in the notes for reporting. However the described system had disadvantages that the drivers sometimes failed in the reporting or registering and the accurate control of the amount of supplied fuel could not be effectively made.

The present invention is intended to remove the above drawbacks and solve the problems associated with the fuel supply apparatus commonly used in the gasoline station.

A principal object of the present invention is to provide a fuel supply controlling apparatus which includes a fuel supply apparatus which is capable of supplying fuel only when a specified code board is inserted into a fuel supply controlling unit.

Another object of the invention is to provide a fuel supply controlling apparatus in which the amount of supplied fuel and the code number are automatically registered after the fuel is supplied after inserting a specified code board into a fuel supply controlling unit.

A further object of the invention is to provide a fuel supply controlling apparatus which can automatically register credit code numbers of customers in the sales bill upon selling the fuel on a credit basis to specified customers.

Still another object of the invention is to provide a fuel supply controlling apparatus which includes a detection means having no electrical error and which uses a mechanical means to cooperate with an indentation on the code board for detecting specified numbers of the code board.

Other objects and features of the present invention will be apparent from the following description when considered in connection with the accompanying drawings, in which:

FIG. 5 is a vertical front elevation of another embodiment ofa detecting means of code numbers ofa code board;

FIG. 6 is a perspective view of an embodiment of the code board used in the code number detection means; and

FIG. 7 is a side elevation in vertical fragmentary section of the detection means,

Referring now to the drawings, FIG. 1 is a schematic diagram which illustrates the system of an embodiment of a fuel supply controlling apparatus according to the present invention. A'suction conduitpipe 11 extends from a known fuelsupplying standpost 10mm a fuel reservoir 12 under the ground. As a suction pump 14 driven bya motor 13 operates, the fuel stored in the reservoir 12, for example, gasoline 15 is suctioned up through the pipe 11, which'passes through a flowmeter l6 and a fuel supplying flexible pipe 17, and reaches a fuel delivery nozzle 18. When the nozzle valve of said nozzle 18 is opened the fuel is discharged into a gasoline tank in the vehicle and the fuel supply is carried out.

A fuel supply controlling unit 19 is situated at a location apart from the fuel supplying post 10. The unit 19 has a slit 20 into which a code board as later described is inserted and has a code board detection means accommodated therein. A]- ternately saidcontrolling unit 19 may be provided integrally with the post 10. As the controlling unit 19 has inserted therein a specified code board, an electric signal is transmitted through a connection 21 and an electromagnetic switch 22 is closed. Then an operation switch 23 of the motor 13 is connected electrically to a power source 24 through a connection 25. Simultaneously, a signal receiving and recording part or unit 26 located in a controlling room or an office room apart from the stand post 10 and the controlling unit 19 receives the signal from the controlling unit 19 through a connection 27 and is actuated to be operable.

Upon supplying fuel, first the code board of the specified customer is inserted into the controlling unit 19 whereupon the switch 23 is connected to the power source 24 and simultaneously the signal recording part 26 will operate. When the fuel-supplying operator rotates a handle 28 a linkage mechanism 29 operates effecting the zero resetting of the indication of an indicator 30 and simultaneously the switch 23 is closed and the motor 13 is operated. As the motor 13 operates the gasoline I5 is suctioned up through the pipe 11 as described and is supplied to the vehicle from the nozzle 18. A flowmeter 16 is constructed so that for example a rotor in the interior thereof can rotate at a frequency of rotation proportional to the flow rate of the fuel. Corresponding to the flow quantity of gasoline passing through said flowmeter 16 a flow quantity oscillator 31 generates a signal which is supplied to the signal-recording part 26 through a connection 32. The flow quantity oscillator 31 may either be a cam oscillator of a contact system or a high frequency oscillator of a noncontact system which generates for example a pulse signal in response to the flow quantity of gasoline. The indicator 30 may be directly driven by the flowmeter 16 or it may be so constructed as to be driven by the signal from the oscillator 31.

The signal-recording part 26 has a printer therein and as later described it prints the quantity of supplied fuel and a code number of the code board inserted into the controlling unit 19 on a sales bill. Said signal-recording part 26 may have a means for recording on a tape or means for making indication of the integrally calculated amount of supplied fuel and memory of the flow quantity. Also said printer may be replaced in use by a magnetic tape, perforated tape, perforated card, etc.

Now an embodiment of the code board detection means in the controlling unit 19 will be illustrated in connection with the operation of the printer in the signal-recording part 26 with reference to FIGS. 2 to 4. The means for printing the flow quantity in the signal-recording part 26 in response to the signal from the flow quantity oscillator 31 has been well known, the particulars of which are therefore omitted.

Prior to the fuel-supplying operation as described above, a code board 50 of a plate shape as shown in FIG. 2 is inserted into the controlling unit 19 through the slit 20. When the code board 50 is inserted, a stepped portion 51 provided on the side of the board 50 pushes a spring leaf 53 of a microswitch 52 and closes said switch 52. As the switch 52 is closed three relay coils 54, 55 and 96 in parallel connection as shown in FIG 4 are connected to power source terminals 57a and 57!) through a normally closed switch 56 and are thereby actuated.

As the relay coil 54 is actuated, said electromagnetic switch means 22 is closed and connects electrically the power source 24 with the motor operation switch 23.

As the relay coil 55 is actuated, the relay switch 58 shown in FIG. 2 is operated. A contact member 58a is contacted with the contact points a and b and closes both contact points. A contact member 58b is removed from the contact points and d and opens said latter two contact points. At the forward end of a rotary shaft 60 of a step motor 59 which is rotatable both in the forward or normal and reverse directions is secured to a gear 97 which is meshed with a gear 98 having teeth double the number of the teeth of the gear 97. A rotary shaft 99 provided with and secured to the gear 98 is rigidly secured with a generally circular cam 101 having a recessed 100 portion on the circumference thereof as shown in FIG. 3B. The peripheral surface of the cam 101 is in attachment with the forward ends of spring leaves 103 and 105 respectively of microswitches 102 and 104. When the motor 59 begins its rotation in the normal direction the cam 101 is in a position as shown in FIG. 3B. In this position, the microswitch 102 is closed and the microswitch 104 is opened so that the switch contact member 107 associated with the switch 102 shown in FIG. 2 is closed and the contact member 106 associated with the switch 104 is opened. Accordingly, if the contact points a and b are closed by the contact member 580 as described, the motor 59 is connected to the power source and initiates the rotation in the normal direction.

Then by rotation of the motor 59 the cam 101 rotates through the gears 97 and 98 and when the rotary shaft 60 has turned just one rotation the cam 101 is rotated through one half rotation, being lowered in its rotational speed by the gears 97 and 98. The forward end of the leaf 103 falls in the recess 100 of the cam 101 so that the switch 102 is closed and the contact member 107 is opened, and consequently the motor 59 is stopped in its rotation.

The rotary shaft 60 of the motor 59 is separately rotatably fitted with two rotary cam plates 61 and 62 of the same shape with a determined interval axial spacing or between each other. On the outer periphery of each cam plate 61, 62 are formed, as shown in FIG. 3A, nine stepped projections 63a (64a), 63b (64b), 631' (641') outwardly expanding in a spiral and stepped manner by every one stage at an angular interval of central angle 36 and stepped portions 63] (64j) reaching to a position of minimum diameter at an angular interval of approximately l8 from said projections 631' (641'). Torsion springs 65 and 66 have their one ends respectively fixed to the rotary shaft 60 and their other ends respectively secured to the cam plates 61 and 62. The springs 65 and 66 are in the woundup state to avoid unnecessary movement of the cam plates 61 and 62 and engaged to stop members 67 and 68, the ends of which are secured to the corresponding rotary shaft 60 respec tivelv.

Respectively opposite to each of the cam plates 61 and 62, contact baseplates 69 and 70 are immovably fixed to a chassis frame (not shown). The rotary shaft 60 is rotatably fitted through the plates 69 and 70. The contact base plate 69 (70) is, a shown in FIG. 3, formed with ten contacts 73a (74a), 73b (74b) 73j (74j) consisting of conductors at equal intervals of 36 on the outer periphery ofa baseplate 71 (72) and a conducting contact 75 (76) of a circular shape in the center thereof. There are provided slide wipers 77 and 78 respectively on the cam plates 61 and 62 through insulating plates 79 and 80 which consist of conductors contacting in turn with each one of said contacts 73a (74a) 73j (74j) on the contact baseplate 69 (70) and with a circular contact 75 (76) making them conducting with each other and slidingly rotate on the contact baseplates 69 and 70 with rotation of said cam plates 61 and 62.

The code board 50 is provided at its forward end with two notches 81 and 82 into which the outer peripheral edges of the cam plates 61 and 62 may be respectively inserted. The lengths of said notches 81 and 82 respectively represent the individual coded number of the code board 50. According to the present embodiment said code number has two figures so that two of such notches of the code board are provided, and the cam plates also are two in number but the number of these sets may be desirably provided corresponding to any number of the figures of the code number.

In the middle of the code board there is provided a hole 83. When the code board 50 is inserted through the slit 20 between guide plates 84a and 84b (FIG. 3), the switch 52 is closed to actuate the relay coil 96 as hereinbefore described and a relay switch 88 of FIG. 3A is closed to operate a plunger coil 85. A sliding rod 86 is biased towards the receded position to the right side by a spring 87 and shifts to the left side by operation of the plunger coil 85, whereby the forward end of said sliding rod 86 passes through holes on the guide plates 84a and 84b and hole 83 of the code board 50 and thereby the code board 50 is locked securely at the inserted position.

Before rotation of the motor 59 is started the cam plates 61 and 62 are diametrically located in such way that the positions of minimum radii or positions between the stepped portions 63a, 64a and 63j, 64] are opposite to the code board 50. As described above, when the relay coil is actuated and the contact member 580 of the relay switch 58 is closed, the motor 59 rotates in the normal direction and rotary shaft rotates. Then the stop members 67 and 68 make the cam plates 61 and 62 rotate through springs and 66. It is herein provided that the notches 81 and 82, when the code number of code board 50 is No. 57 for example, are in the lengths respectively corresponding to No. 5 and No. 7. Therefore by rotation of the motor 59 the cam plate 61 rotating in the clockwise direction in FIG. 3A is engaged to or abuts against the notch 81 of the code board 50 at the stepped portion 63f and the cam plate 62 is similarly engaged to or abutting against the notch 82 at the stepped portion 64h. After the cam plats 61 and 62 are engaged to the notches 81 and 82, the rotary shaft 60 continues to rotate and thus winds up the torsion springs 65 and 66. When one rotation of the rotary shaft 60 has been accomplished the motor 59 stops its rotation as previously described.

With the rotation of the cam plates 61 and 62 the wipers 77 and 78 simultaneously rotate slidingly on the contact baseplates 69 and 70. When the stepped portion 63f of the cam plate 61 is engaged to the notch 81 the wiper 77 attaches the contact 73f and the contact making these contacts conducting and when the stepped portion 64h of the cam plate 62 is engaged to the notch 82 the wiper 78 attaches the contact 74h and the contact 76 making these conducting.

Upon completion of the fuel supply from the fuel supply stand 10, the operator may return the handle 28 to the initial position whereupon the operation switch 23 is opened and the motor 13 is stopped in its rotation, when a known printer of fuel supply in the signal receiving and recording part 26 is actuated and prints the amount of fuel supply on the sales bill 33. The above-mentioned printer may be constructed so that it can simultaneously record the date and time, kind of fuel, number of a fuel supply meter, name of operator and the like on the sales bill. After printing of the amount of supplied fuel on the bill 33, a printout signal is sent to a step relay 89 which actuates to connect the contact member from a nonoperated contact 95 to a contact 90 with a relay coil 91 being connected to the power source terminals 57a and 57b and it is thereby actuated. As the coil 91 is actuated a relay switch 92 is closed. Coils 93a to 93j for exciting ten keys of printing numbers from 0 to 9 are respectively connected to the contacts 73a to 73] of the contact baseplate 69 and the contacts 74a to 74j of the contact baseplate 70. Thus when the switch 92 is closed, the key coils out of the coils 93a to 93j are closed and actuated through the relay switch 92, the contact 75 connected to said switch, the wiper 77, and the contact to which the wiper 77 is in contact out of the contacts 73a to 73j, and thereby the printing on the bill is effected. In the present embodiment, as the wiper 77 contacts to the contact 73f, the key coil 93f of the numeral 5 connected to the contact 73f operates and the numeral 5 is printed.

As the printing of numeral 5 is made through the key coil 93f the signal indicating the completion of printing is sent to the step relay 89 which is switched over from the contact 90 to the contact 192 in connection. At this time the relay coil 91 is opened in a deenergiied state so that the switch 92 is opened and the circuit including the contact baseplate 69 is opened. On the other hand the relay coil 193 is closed and actuated so that relay switch 94 is closed. Upon closing of the switch 94 the key coil 93h of numeral 7 connected to the contact 74h is actuated through the contact 76 connected to said switch, the wiper 78 and the contact 74h connected to said wiper, and thereby the numeral 7 is printed. Thus the number 57 is printed by this operation eventually. The apparatus of the present invention may otherwise be designed such that it may have a memory device to integrally memorize the total amount of fuel supply, for example on a monthly basis and in the order of numbers as detected simultaneously as the number such as 57 will be printed. When the printing of the numeral 7 through the key coil 93h is accomplished and the bill 33 is printed out, there is sent a signal indicating a completion of printing to the step relay 89, which is again switched over to the nonoperated contact 95 with a switch 94 being closed and the circuit system with the contact baseplate70 being opened.

When printing of the keys corresponding to specified coils out of the above key coils 93a to 93j is finished and the bill is printed out, the switch 56 is temporarily opened by the signal for indicating the completion of printing and the relay coils 54, 55 and 96 are opened for deenergization. By deenergization of the coil 54 the electromagnetic switch means 22 is opened and the operation switch 23 is electrically disconnected from the power source 24. In order to close the operation switch 23 so as to supply fuel again, it is required to insert a new specified code board in the slit of the controlling unit 19. Further, by deenergization of the relay coil 55, the contact member 58a is opened simultaneously as the contact member 58b of the switch 58 is closed and rotation of the motor 59 is stopped. By deenergization of the relay coil 96 the switch 88 is opened and the plunger coil 85 becomes deenergized and the sliding rod 86 shifts rightwardly by force of the spring 87 whereby the locking of the code board 50 is released. Therefore the code board 50 is rejected and pushed from the controlling unit 19 a predetermined distance by the spring leaf5l of the switch 52 and remains in a free condition, and the switch 52 is thereby opened.

As described above, when the motor 59 turns just one rota tion in the normal direction, the cam 101 rotates through a half turn from a position as shown in FIG. 3b when the switch 104 is closed and accordingly the contact member 106 is closed. Therefore when the contact member 58b is closed as described above the motor 59 rotates in the reverse direction, as its reverse circuit is connected to the power source through contact members 5812 and 106 or when the motor 59 makes one rotation in the reverse rotation or the cam 101 makes a half rotation the contact member 106 is closed and the motor 59 stops its reverse rotation.

In the embodiment hereinbefore described the-code numbers of the code board 50 are 5 and 7 and the lengths of notches 81 and 82 are provided so as to correspond, to said numbers. Thus generally the lengths of notches 81 and 82 may be set corresponding to the code numbers as preferred. On the occasion when the lengths of the notches 81 and 82 are the shortest said notches are engaged with the stepped portions 63a and 64a and when the lengths of notches are the longest said notches are not engaged by the stepped portions 63i and 641' but the cam plates 61 and 62 make just one rotation and stop.

Another embodiment of the code board detecting means is now illustrated with reference to FIGS. 5 to 7 in which the same numerals designate like parts as in FIGS. 1 to 4.

Before the fuel supply operation a code board 150 as of .a' shape shown in FIG. 6 is inserted into the controlling unit'19 through the slit 20 on the right side of FIG. 7. The code board 150 is provided with racks 151 of toothlike shape ,on the upper surface thereof, on theright and the left sides of the forward end of which are respectively provided plane portions 153 and 152 of the specified lengths. The lengths of said plane portions 152 and 153 are the lengths corresponding to the code numbers proper to the code board 150 so that the lengths of rack portions 154 and 155 excluding the plane portions 152 and 153 on the left and right edges of the rack 151 likewise have lengths representing the code numbers.-

A fixed shaft 160 secured to achassisgframe (not shown) is loosely fitted with two rotatable gears 156 and 157 of the same shape at an axial interval or spacing-shown in FIGS. 5 and 7.

The gears 156 and 157 are provided on their outer periphery with teeth meshing with racks of the rack portions 154 and 155. The gears 156 and 157 have torsion springs 65 and 66 between fixed shaft 160 which are engaged with the stop members 67 and 68 as in the above embodiment. Also the gears are provided with the wipers 77 and 78 to engage to the contacts 73a to 73 and 75 and the contacts 74a to 74j and 76 v of the contact base boards 69 and 70 secured to the shaft 160.

By insertion of the code board 150 from the slip 20 the plane portions 152 and 153 of the board 150 pass underneath the gears 156 and 157 which will thus remain stationary. By further insertion of the board 150 first the gear 156 will mesh with the rack of the'rack portion 154 and start its rotation winding up the spring 65. By further insertion the gear 157" also meshes with the rack of the rack portion 155 and rotates in winding up the spring 66. When the board 150 is completely insertedinto a predetermined position the gears 156 and 157 respectively rotate by the number of teeth corresponding to the lengths of the racks of the rack portions 154 and 155.

When the code board 150 is inserted through the slit 20 to the predetermined position as described, the leaf 53 of the microswitch 52 is pushed by the forward end of the board 150 and the switch 52 is closed. Upon closing of the switch 52 the plunger coil is actuated and the sliding rod 86 moves downwardly fitting through the holes of guides 158a and 158b and a hole 159 of the board which in turn is locked at the position of its insertion.

In case the code board 150 has a code number 64 in this example the racks of the rack portions 154 and respectively have the teeth of thelengths corresponding to the numerals 6 and 4. Therefore by insertion of the code board 150 the gear 156 is rotated through a specified angle, corresponding to numeral 6 and the wiper 77 rotates slidingly on the contact base board 69 by rotation of the gear 156 and stops in contact with the contact 73g. And by the insertion of the code board 150 the gear 157 is rotated through the other specified angle, corresponding to numeral 4 after the gear 156 starts its rotation, and the wiper 78 rotates slidingly on the contact base board 70 by rotation of the gear 157 and stops in contact with the contact 742.

The electrical circuit system including the contacts 73a to 73j, 75, 74a to 74j, 76 of the contact base boards 69 and 70 and printing key coils 93a to 93j'has the same design as in the first embodiment of FIG. 4 in which the step relay 89 is changed over and connected consecutively to the terminals 90 and 92 and the key coils 93g and 93s respectively connected to the contacts 73g and 74e, are consecutively actuated, whereby the numerals 6 and 4 are printed consecutively, in consequence the number 64 is printed. Operation of the other circuit components is quite identical as in the above-described embodiments.

While the invention has been described with respect to the specific and preferable embodiments, various modifications and variations thereof will be apparent to those skilled in the art without departing from the scope of which is set forth in the appended claims.
