UNITED STATES JOHN WALTER JOHNSON, F BLUEFIELI), WEST VIRGINIA.

GASOLINE-VENDING MACHINE.

Application filed February 18, 1924. Serial No. 693,610.

To all whom it may concern:

Be it known that 1", JOHN W. JOHNSON, a citizen of the United States, residing at Bluefield, in the county of Mercer and State of West Virginia, have invented a new and useful Gasoline-Vending Machine, of which the following is a specification.

The present invention relates to gasoline dispensing devices, and aims to provide a device of this character which will be check or coin controlled.

The primary object of the invention is to provide a device of this character wherein a purchaser may, by inserting a coin in a suitable slot obtain a predetermined quantity of gasoline, novel means being provided for insuring the exact quantity of gasoline paid for, being dispensed from the device.

Another important object of the invention is the provision of means for regulating the quantity of gasoline dispensed through the discharge pipes of the device so that the quantities of gasoline dispensed may be varied according to the change in price of gasoline.

A still further object is to provide means for automatically maintaining the tank in a filled condition, means being provided to insure against the filling of the tank While fluid is being dispensed therefrom.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts. and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is a front elevational view of a gasoline dispensing device constructed in accordance with the invention.

Figure 2 is a longitudinal sectional view through the device, taken on line 22 of Figure 3.

Figure 3 is a longitudinal sectional view through the device taken on line 3-3 of Figure 2.

Figure 4 is a sectional view taken on line 4-4 of Figure 3.

Figure 5 is a sectional view taken on line 5-5 of Figure 3.

Figure 6 is an enlarged "detail view disclosing contact members.

Figure 7 is a sectional view float controlled members.

Figure 8 is a diagrammatical view disclosing the electric circuits that control the operation of the device.

Referring to the drawings in detail, the reference character 5 designates the tower or dispensing device which may be of an desired construction. Supported within the tower 5 is a tank 6 which receives gasoline through the pi e 7 that is in communication with the supp y tank 8 through the pipe 9, there being interposed between the pipes 7 and 9 a rotary pump 10 mounted on one end of the motor 12 that receives electric energy from the battery 13.

As shown, the motor 12 is in circuit with the battery 13 through the wires 14; and 15, there being provided a manually controlled switch 16 designed for completing the circuit to the motor to control the operation of the motor.

A plurality of contact points 17 are arranged in pairs and are adapted to be bridged by means of the contact plates 18 carried by the valve operating arms 19 to be hereinafter more fully explained, so that when the arms 19 are moved inwardly to operate the Valves controlled thereby, the members 18 will be moved out of engagement with the contact points 17 to break the clrcuits to the motor.

Switch members 20 are supported within the tower 5 and are adapted to be bridged by the contact arm 21 carried at the lower disclosing end of the rod 22 that has pivotal connection with the arm 23 disposed at the upper end thereof, the arm 23 having connection with the float 24 so that as the float moves upwardly and the gasoline level in the tank reaches its upward limit, the circuit to the motor will be broken by the disengagement of the arm 21 with the contact members 20.

Extending into the tank 6 are discharge pipes 25 of various lengths, each of which pipes 25 being provided with a threaded upper extremity 26 desi ed to receive a threaded sleeve 27 where y the lengths of the pipes may be varied at the will of the operator.

These pipes 25 communicate with a discharge pipe 28 through the relatively short pipes 29, the passage of gasoline through the I pivoted arm 33 that engages the lug 34 of the arm 19 associated therewith, there being provided an adjustable weight 35 on one end of the arm to cause the arms to be operated by coins of various weights.

Disposed directly above the arms 33 are coin chutes 36, which coin chutes are of various sizes to accommodate coins of various sizes .so that when coins are dropped into the chutes 36 they will engage the arms 33 to move them out of engagement with the lugs 34 to release the arms 19 and allow the same to be manually operated.

"Coiled springs 37 are positioned on the arms 19 and normally act to draw the arms 19 to their initial position, there being provided a pin 38 on each arm 19 to engage the inner edge of the casing 39 or coin box to prevent the arms 19 from being withdrawn to operate the valve members.

An overflow pipe indicated at 40 provides communication between the tanks 6 and 8 to return a surplus amount of gasoline contained in the tank 6, to the tank 8 and insure against the tank 6 overflowing.

A drain pipe 41 also establishes communication between the tanks 6 and 8 to permit the gasoline within the tank 6 to be drained therefrom, and should it be desired to repair the tank or mechanism of the dispensing device.

A suitable hose not shown may be connected with the discharge pipe 28 so that the gasoline may be directed to a motor vehicle tank or container in which the gasoline is to be placed.

The operation of the device is as follows Assuming that it is desired to purchase fifty cents worth of gasoline, a fifty cent piece is inserted in the slot designed to receive the same, whereupon the arm 33 disposed thereunder, is operated, releasing the arm 19 associated therewith to permit the valve controlled by the arm, to be moved to its open position.

The gasoline in the tank 6 is now permitted to flow through the discharge pipe which has been opened by the movement of the valve, it being obvious that the gasoline will continue to flow until the level of the gasoline is below the upper end of the pipe, through which gasoline is moving. It is obvious that as the level of the gasoline in the tank 6 is lowered, the float 24 moves down wardly causing an upward movement of the arm 22, which results in a movement of the arm'21 to complete a circuit to the motor through the members 20. I

The member 18 of the arm operates to release a quantity of gasoline, having been moved out of contact with its contact oints, the circuit to the motor 12 remains roken until the desired quantity of gasoline has flowed from the tank 6 and the arm has been released by the purchaser, whereupon the coiled spring associated with the arm returns the arm to its initial position and completes the circuit to the motor with the result that the motor operates to fill the tank 6 with gasoline from the tank 8.

As the tank becomes filled, the float 24 is moved upwardly resulting in a downward movement of the arm 22 to break the circuit between the arm 21 and members 20 causing the motor to cease pumping.

I claim A gasoline dispensing device including a tower, a tank mounted in the upper portion of the tower, a plurality of discharge pipes Within the tank, valve members for controlling the passage of fluid through the discharge pipes, switch members disposed adjacent to the valve members, valve operating arms associated with the valve members for operating the valve members, contact members carried by the arms and adapted to complete circuits through the switch members when the operating arms are in their normal positions, a motor driven pump for forcing fluid into the tank, switch members within the tower and in circuit with the motor, a vertically movable float actuated rod carrying a contact arm at its lower end adapted to complete the circuit to the motor when the rod is moved to the limit of its upward movement, to supply fluid to the tank, and said fioat actuated rod adapted to move to break the circuit to the motor when the fluid in the tank fills the tank.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.

JOHN WALTER JOHNSON.
