To all whom it may concern:

Be it known that I, Gaonon An'rus, a citizen of the United States. residin at Clear Lake, in the county of Deuel an State of South Dakota, have invented certain new and useful Improvements in Automatic Gasolene and Oil Venders, of which the following is a specification.

This invention relates to vending machines for dispensing liquids automatically in a measured amount corresponding to the denomination of thecoin inserted.

The main objects of my invention are to provide an apparatus dispensing liquids of different grades which can be predetermined by the purchaser and in varying amounts automatically controlled by the denomination of the inserted coin.

The invention will be understood from the following detailed description in connection I with the accompanying drawings, in which Figure l is a diagrammatic view of anapparatus embodying my invention; and Fig. 2 is a detail view of a modified form of one of the parts. For the purposes of clearness I have not shown the sup orting framework. A suitable number of coin chutes 1 graduated in size to receive coins of different denominations' are provided which lead to the shallow grooves 2, 2, etc., in the coin-cylinder 4, these grooves being a depth to permit the coin to project beyond the periphery of the cylinder. Corresponding with the grooves and in a position to be engaged by the coins when the cylinder 4 is rotated, are a series of swinging levers 6, 6, pivoted at their upper ends 6 A coin in one of the grooves will engage one lever or the other, pushing it away from the cylinder, and. actin through the links 8, 8, rotates the bell-era g the dog 15, carried by the arm 12, to swmg the weighted inverted pendulum 17, forward upon the horizontal pivot 18. As the dog 15, slips off the side of the pendulum rod 16, the spring 19, causes the pendulum to fly back with suflicient force to strike a hammer blow upon the lug 20, thereby rotating the switch 21 and causing the blade 23 to engage the contact- 24, thus closing the circuit of the electric motor 25,

connected to the pump 26. This movement of the switch, acts through the link 28,- to

lever 9, 10, 12, upon its pintle 14, and cans lift the arm 30, pivoted at 31, and which will return the swltch to off position when it is engaged by one of the stop lugs 32, 33, 35 or 36, in a manner hereinafter described.

When the pump 26 is driven by the motor, the gasolene or other liquid will be pumped from the main supply pipe through the pipe 38, into the dispensing tank 40. As the tank is being filled the float 42, rises and causes the cable 43 to gradually lower the cross-head 45, carrying the stop rods 46, 47, until one of thestop-lugs strikes the arm 30, causing it to descend and swing the switch 21 to the of! position with the blade 23 resting upon a back-stop 22, thereby breaking the circuit and stopping the motor.

I have shown four stop lugswhich are adjustable on the rods 46, 47 and are arranged atdiiferent elevations corre 0ndinigl with different quantities of liqui that w tor operates for correspondng periods of time. These stops may be set to different .points on the rOdS in accordance with the be pumped into the tank when the mo- Patented Feb. 5, 1918.

are suspended from the block or cross-head 45, carried by the swivel 49 on the end of the cable 43. g

The pump may be connected to either supply pipes 56, or 57 so that different grades of oil may be supplied. This may be con-' trolled b rocking the control lever 60, either to the right or to the left, thereby swinging the valve 61, to open communication with one supply pipe or the other. Then by pushing the lever forward the link 62, and arm 63 will turn the guide 51 causing the block 45 to turn on the turnbuckle 49 as a pivot and bring the rod 46 adjacent the lever 30 so that the stops 32 and 33 will be in alinement therewith. By pulling the control lever 60 in the opposite direction, the link 62 will swing the block 51 in the reverse direction to thereby oscillate the block 45 on the pivot 49, bringing the rod 47 adjacent the lever 30 and the stops 35, 36

in alinement therewith. These preliminary will cause the actuation of the pendulum 17 to throw the switch 21 and thereby close the circuit through the motor 25. The manner in which the different coins determine the particular stop that shall engage the lever 30 is as follows :If a coin is inserted in slot 2, the lever 6 will be engaged by the coin when the cylinder 4 is rotated by the handle 7, pushing the lever back and caus-v ing the bar 11 to oscillate in a clockwise direction upon its pintle 13, thereby swingin the arm .70, in a clockwise direction an causing the bell-crank 71- to move on its pivot 2 in a direction to %ush the link 74. and guide 50 forwardly. he rod 46 will thus be swung toward the arm 30, causing the lower, shorter stop 32 to be in direct vertical alinement with said arm. Under these conditions, the float 42 in the tank can only rise until the cable 43 descends sufficiently to cause the lower sto 32 to strike the arm 30 and lower it sufficiently to open the switch 21 thus breaking the motor circuit.

If, however, the proper coin is inserted in the slot 2*, the rotation of the cylinder 4 thereby oscillat ng will cause the lever 6 to swing backward,

the bar 11 in an anticlockwise direction and causing the bellcrank 71 to pullthe guide 50 backward. This movement swings the rod 46 away from the arm 30 sufliciently to move the lower stop 32 out of alinement with the arm 30 but leaving the longer upper sto 33, still projecting thereover. Consequent y the motor will continue to operate until the float has risen to a higher level, sufiicient to permit the descending stop 33, to engage the lever 30, to open the switch 21 in the manner described. I have deemed it suflicient for purposes of illustration to show two coin slots and the mechanism controlled thereby to determine the period of operation of the motor driven pump, but it is obvious that I may provide any desired number of coin slots with a corresponding number of cooperating elements to effect the proper movement of the stops.

Instead of placing the arm 30 at one side.

of the stop rods, I may place it between the rods; and I may alsoplace upon one bar 46' as-shown, for instance, in Fig. 2, the bar being turned axially by the lever 60 in substantially the manner previously described.

The valve 75, in necting with the hose open and be automaticallv maintained closed while the tank is being filled in any suitable manner, as for instance by connection with all of the stops the outlet pipe 76, COI1- 78, may be normally the float or with an operating part of the I I um I have shown the valve controlled by suitable lever mechanism 80, with a centrifugal governor 81, on the shaft of the pump. When the pump is in operation the valve will be maintained closed, and will be opened when it stops, permitting the contents of the tank to flow out through the hose 7 8 and nozzle 79.

I The operation of my liquid vender will be understood from the foregoing detailed description. When oil. or other liquidol different grades is supplied, the particular grade or quality is determined by the lateral movement of the control lever 60, and the set of quantity stops covering the range of prices which include the coin which is to.

'to swing the pendulum 17, and cause it to rebound with a hammer blow upon the lug .20, causing the switch arm 23 to close the circuit of the motor 25 to thereby actuate the pump 26. The particular denomination of the coin deposited controls the direction of movement of the bar 11, and the consequent swinging movement of the rods 46, 47 which determines the particular stop lug that shall engage the arm 30, to open the motor switch when the tank .float has risen sufiiciently to lower said stop. Upon the stoppage of the motor and pump the valve 7 5 automaticallly opens to discharge the contents of the tan I have particularly described the mechanism illustrated in the accompanying drawings for the express purpose of clearly disclosing an embodiment of my invention but I am aware that various changes and modi fications can be made within the scope of my claims and without in any manner departingfrom the scope of my invention.
