Referring first to'FIGS. l and 2, there is shown a gasoline dispensing pump. 20having a liquid gasoline dispensing hose 22 provided at it's freeend with a nozzle 24 and manually operable trigger valve 26. The pump has a computer 28 provided with counter scales29, 30 and 31 indicating respectively the amount of the last sale of gasoline in dollars and cents, the number of gallons dispensed in gallons and tenths of gallons, and the price of the gase line in cents and tenths of acent per gallon. Onthe front of the pump is a viewing window 21 to show when gasoline is flowing out of the pump. A crank-handle 23 is provided for resetting the saleand quantity scales 29,30 of the computer to zero indications. Gasoline -:is supplied tothe pumpvia pipe 32 from an underground tank." To the exten d r d; he nu plfl s e i e conventional and reference may be made to "US. Patent 29952 9 f r ald sc ip ionc intern W n p r s- Mounted on one side of the pump opp osite to the hose 22 is a cabinet 35 containing a coin controlling mecha sm- Q si e W 36 Q th cas s a d '3 supp ing a coin receiving apparatus 39 inside the cabinet. In
Patented June 8, 1965 door 38 are three slots 40, 41 and 42 of successively larger sizes for receiving coins of difrerent denominations such as dimes, quarters andhalf dollars. The'door has a key operated lock 44 at one edge. Beneath the slots 40-42 is a coin return trough 46 for returning and collecting defective coins which may be deposited in the slots. At the bottom of side wall3 6 is a door 48 providing access to the interior of the cabinet. This door has a suitable lock 49. Adjacent to the slots is an operating knob 50. ,On the front wall 52 of the cabinet is lock 54 foroperating a control circuit C of the device. This circuit C is shown in FIG. 3 .to which reference will be made. Abovethe cabinet is a sign 55 marked on-the transparent Wall of a lamp housing 58 containing lamp 50. When the lamp 60 is energized,.the legend SELF SERVICE COIN OPERATED ofthe sign is illuminated. H i
1 Referring now to FIG. 3, it will be noted that there is provided a motor 62 which operates the-pump ;fordispensing gasoline inliquid form. The motor is connected in series with normally closed push-button switch 64. Swith 64 may be located in the hose supporting receptacle .65 on the side of. the pump. The switch opens'when valve- 26 is installed in the receptacle to press'the button 66. The. switch closes when the valve 26 is removed fromthe receptacle. i The motor .62.is connected in series with a coin controlled relay circuit and terminal 7 1 of apower supply. Lock 54 controls ganged poles 72,73 of a double pole-double throw switch Pole 72 closes with fixed contactu'76 in one position ofthe switch. Lamp 60 is connected in series with pole 72, contact 76 and power supply terminal 81. Pole 73 closes with fixed contact 80. in another position of the switch. Pole 73 and contact 80 are connected in a shorting circuit 82 for short circuiting the relay circuit 70 when thedevice is set' for manual control. 1 The relay circuit is operated by a coin or coins of suitable denomination deposited iii slots 40- 42, and by pressing of operating knob 50. Reference should .be made to the above-mentioned Patent 2,995,229 for details of the circuit 70 and associated mechanical parts. r
In operation of circuit C, the operator may turn lock 54 with a suitable key to set switch 75 for manual or jcoin control of the device. In FIG. 3, the circuit is set for coin-controlled operation. A direct electrical connection will exist between terminal -71 and motor 62 if a suitable coin or coins are deposited in slots 40-42, so that the motor 62 operates when switch 64 is closed. If the nozzle valve 26 is placed in receptacle 65, the switch 64 will open to shut off the motor. Lamp 60 is energized and the sign 55 is illuminated indicating to a customer that the device is under coin control. B'y depositing suitable coinsin the slots 40, 41, 42 and pressing knob 50, all according to the arrangement of the above-mentioned patent, a quantity of gasoline will be dispensed from hose 22 dependingon the dollar amount of the coins deposited.
The coin control arrangement will be effective while the device is unattended by an operator sothat motorists can senve themselves. Suppose now that an attendant becomes available. The operator will insert the cootrolkey and each circuit controls its own only a single circuit C I ato'r.
"for, dispensing cans of high tester high octane gasoline so is mounted on the front of each cabinet 35 and 35* tor manual operation when the lock 54 is set to manual openating position. Two identical control circuits C are provided for the devices. Since the circuits are identical can dispensing device, is shown in RIG. '6. A can reeeiving trough 1% is provided at the front of each cabinet for retaining a can or gasoline G discharged therein when thedevice is operated under coin control. Other parts oi the devices N2, 102' corresponding to those of de ice as are identically numbered. A single coin re be ing slot 41 is provided in each coin receiving cabinet as, ss a Referring now toFIG. 6,'it will be noted that switch "75 which is controlled by lock" 54 is a triple poledouble throw switch. The coin controlled relay '70 connects can dispenser motor 62 directly to power supply terminals 71, 31* when poles 72 73a, 74* are in the right or coin control position as shown in the drawing. Push-button switch 64 is short circuited since pole 7 2 is closed with fixed switch contact 1%. Lamp 63 is illuminated since pole 72 is closed with contact '76 The shorting circuit 82 is open since pole 73 is open with respect to fixed contact 89 The device can operate unattended; as each coin is deposited in slot 41 inotorist who serves'himself upon discharge of a can G- Suppose that the device'is to be attended by an oper- 54 and set switch '75 for manual operation. Pole 73 closes with contact 8% and the circuit it; is short circuited; Pole 72 opens with respect to contact i6 and lamp se is extinguished. Pole '74 opens with respect to contact 108 so thatswitch 64 is activated. Theoperator' can now manually close switch 64* each time a can is to, be dis pensed from the device without'having to deposit a coin in slot 41?.
In FIGS. 7 and 8 is shown an apparatus I5tlincluding both liquid dispensing pump as and can dispensing device 102. Coin receiving cabinets 35, 35 are associated with and attached to sides of the pump and'can dispensing cabinet 104, respectively. The coin receiving cabinets 35,
, 35 are turned 90 fnom'their positions in FIGS. 1 and-4,
but are otherwise'identical in structure and corresponding pants are identically numbered. On side wall 152 of the device a is a door 116 closed by a lock 112. lnside this door, as shown in FIG. 9, are three key operated locks 54, so and 114. a s
FIG. 10 shows the control circuit C"--of theapparatus 150. Parts corresponding to those of circuits C and C are identically numbered and operate in the same ways as previously described. 'Lock 114 controls a double polethree position switch 115. The center position is the OFF position and the poles 116, 117 are open circuited. At the left or GAS position of switch 115, power supply terminals 71 81 are connected to fixed contacts 118, 1-19 so that the left circuit portion C is activated. Then the operator can set switch '75 controlled by lock 54 to either manual or coin control positions as above described in connection with circuit C. If switch 115 is set to the right 'or CAN position, then circuit C is deactivated and circuit C is activated as poles 116, 117 close with contacts 120, 121 and connect terminals 71 81 to circuit C. 'Now the operator can set switch 7-5 to either coin or manual control by appropriate settingof lock 54*. Three different keys are required to operate the several locks 54, 54 and 114 of apparatus 150. In addition, a fourth key is required for opening lock 112 to gain access to the circuit by a" The operator will insert the suitable key in lock 9 aromas control; locks. This arrangement insures security against the appended claims. I

The apparatus described can be installed at gasoline stations in association with conventional manually operated liquid gasoline dispensing pumps, to provide gasoline dispensing service to motorists when the station is closed or otherwise unattended. Alternatively, the apparatus can be installed at locations such as along road-sides where it may not be economically feasible to maintain a full-time attendant.
j cabinets, are provided with any type of locked hinged doors for refilling the cabinets. I
It is to be understood that a suitable refrigerating un t may be'installed in the cabinet to keep it in cool condition during hot weather.
