APPARATUS FOR DISPENSING GASOLINE AND THE LIKE.

' Application filed September My invention relates to an improvement in apparatus primarily designed for dispensing gasoline at filling-stations but not so limited, the object being to produce, at a relatively low cost for manufacture, a simple, compact, conveniently-operated and re-- liable apparatus preferably constructed so as to be electrically started and mechanically controlled during the remainder of one cycle of its operation.

With these-ends in view, my invention consists in an apparatus for dispensing gasoline, and kindred fluids, characterized by its adaptation to being mechanically controlled during a cycle of its operation after having been once started, whether electrically or manually.

My invention further consists in an apparatus characterized as above and having certain details of constru'tion and combinations of parts as will be hereinafter described and pointed out in the claims.

For the illustration of in invention I have shown an apparatus or dispensing gasoline by specially designed tokens having the grooved character of pin-tun} 13, 1927. Serial No. 219,236.

bler-lock keys and designed also to be operated, if desired, by push-buttons The apparatus illustrated provides for dispensing one, five or ten gallons of gasoline in one cycle of its operation, depending upon which of tlie'tliree of its measuring-units is initially started, but, of course, the amount of gasoline, or other fluid, dispensed may be varied as desired by mere mechanical changes in the ii'ieasurmg-units.

The apparatus herein illustrated, which may be operated by push-buttons or pluglike tokens, comprises three measuringunits, all installed upon a drive-shaft 10 driven by a flow-meter or fluid-motor 11 of any approved construction and not calling for detailed description more than to say that itis provided with an inlet or supplypipe 12 connected with a source of asoline under pressure, and an outlet or service-pipe 13 which ultimately leads to a hose or nozzle (not shown) for filling the gas-tank of an automobile, interposed a valve 14, the reciprocating stem 15 of which is encircled by a sprin 16,- by means of which the valve is normal y maintained in its closed position. The said valvestem 15 is depressed against the tension of the spring 16 for opening the valve and per- ,mitting the flow of gasoline, through the flow-meter 11 and service-pitpe 13, by its engagement with the lower 1 ace of a valveoperating arm 17 mountedon a rock-shaft 18 journaled at its opposite ends in the end walls of the housing 75 of the apparatus.

An operating-arm 19 on therock shaft 18 is formed in its forward end with a downwardly-opening notch 20 receiving a conpling-pin 21 laterally'ofisetting from a measuring-finger 22 having a trian lar nose. 23 for co-action with either one 0 two diametrically-arranged V-shaped measuring-notches 24 formed in the eriphery of a ten-gallon measuring-disk 25 ioosely mounted upon the shaft '10 aforesaid. The said .notch 20- and pin 21 form, in effect, a. one-way driving-connection between theseveral measuring-fingers 22 and the valve 14, in so far as the measuring-fingers 22 can move the arms 19 upward, but the arms cannot so move the measuring-fingers.

The said disk 25 is provided with a guarddisk 26 hearing against one of its faces, loosely mounted upon the drive-shaft 10 and having'oscillatory movement with respect to the disk 25, such movement being and receiving a stop-pin 28 carried by the' limited by a segmental slot 27 formed in it measuring-disk 25. The said guard-disk 26 is formed with two diametrically-op osite complementary guard-fingers 29 whic are snapped under the point of the nose 23 of the measuring-finger 22, at the moment the said nose is lifted out of either one of the i notches 24. by means of a helical spring 30 extending between the said stop-pin 28 and a pin 31 carried by the guard-disk, whereby the nose 23 is prevented from re-entering the given notch 24before the same has, in the rotation of the measuring-disk 25, been carriedclockwise forward out of line with the nose. I

- The measuring-disk 25, its guard-disk 26,

the measuring-finger 22, the arm 19, an armature 51, and a solenoid such as 53,54 or 55, constitute what, for convenience, I have designated as a "measuring-unit. The particular measuring-unit being described is 10- cated next adjacent to the flow-meter 11 and is flanked on the opposite side there- 'from by two corresponding measuring-units,

from which it differs only in the number of the measuring-notches in its measuring-disk 25 and the number of guard-fingers in 'its guard-disk 26. Thus, the disk 25 has two measuring-notches for dispensing ten gallons of gasoline for each measuring-cycle (a half revolution) of its operation, while the measuring-disk 32 of the intermediate measuring-unit has four measuring-notches 33 and its guard-disk 34 four guard-fingers 35, this intermediate unit being designed for dispensing five gallons of gasoline for each measuring-cycle (a quarter revolution) of its operation. The measuring-disk 36 of the remaining unit is formed with twenty measuring-notches 37, while its guard-disk 38 has twenty complementary guardfingers 39, the disk 36 being thus adapted to dispense one gallon of gasoline for each measuringcycle (a twentieth revolution) of its operation. The other parts of the five-gallon and one-gallon measuring-units respectively duplicate the parts of the ten-gallon measuringunit, are correspondingly numbered, and do not, therefore, call for individual description.

and 36 is formed upon its outer face with a circular series of twenty equally-spaced coupling-sockets 40, any pair of which" is adapted to receive a pair of coupling pins 41 projecting laterally from a spool-likeing upon a horizontally-arranged shaft 47,

Each of the three measuring- disks 25, 32

ing-units and will be correspondingly numbered.

Each of the measuring-fingers 22 is mounted upon the lower end of a solenoid armature or core 51 extending upward into the concentric passage 52 of a solenoid, of which there are three, namely, 53, 54 and 55. The solenoid 53 is connected with a circuitwire 56 controlled by a push-bottom 57 the solenoid 54 is conneeted'by a circuit-wire 58 with. a. push-button 59; While the solenoid 55 is connected by a circuit-wireyGO with a pushbutton 61. Having thus described the organization of my improved apparatus, I will nowproceed to describe one cycle of its operation, choosing for such descriptiveillustration its use for dispensing five gallons of gasoline, for which purpose the measuring-unit comprising the measuring-disk 32 is employed.

To electrically start the unit in question, the vendor operates the push-button 59 whereby the solenoid 54 is energized with the effect of lifting its armature 51 and hence its measuring-finger 22 out of the measuring-notch 33 of the disc 32 into which it was, at the time, entered. The described withdrawal of the .finger 22 from the notch permits the spring 30 to move the guarddisk clockwise, whereby the adjacent guardfinger 35 is snapped under the nose 23 of the measuring-finger 22, so that the same is prevented from dropping back into the notch 33 from which it has just been lifted; Simultaneously with the action described, the cam-surface 49 of the measuring-finger 22 operates through the cam-head 48 of the rocking-lever 46 to rock the same and so effect the insertion of the coupling-pins 41 of the clutch 42 connected with it into a pair of sockets 40 in the outer face of the measuring-disk 32, whereby the same is coupled with the drive-shaft 10 for clockwise rotation therewith. Simultaneously also with the liftin of the measuring finger 22, its pin 21 1i ts the arm-19 and depresses the arm 17 so as to open the valve 14 in the service-pipe 13. Gasoline instantly starts to flow through the flow-meter 11, with the effect of driving the shaft 10 and so rotating the measuring-disk 32 for a quarterturn, when its next succeeding measuringnotch 33 will be brought under the measuring-finger 22 which then drops by gravity into it. Concurrent with the described descent of the measuring-finger the rocle ing lever 46 is rocked by its spring 50 to' retract the coupling-pins 41 of its associated spool-like clutch 42 from the sockets sit) in the outer face of the measuring-disk 32, with the effect of uncoupling the same from the drive-shaft 10. Concurrently, also, with the described descent of the given measuring-finger 22, .the valve-spring 16 asserts itself to lift the valve-stem 15 and hence the valve 14 and so stop the flow of gasoline through the service-pipe 13, which stops the rotation of the flow-meter 11 and the rotation of the drivcshaft 10 after it has made a quarter-turn. All this takes place as soon as five gallons of gasoline have been allowed to pass through the service-pipe 13. The apparatus, as shown and described, 'is so organized that the shaft 10 makes but one complete revolution for the dispensation of twenty gallons of gasoline.

In the same manner, the use by the vendor of the push-button 57 energizes the solenoid 53 and starts the ten-gallon measuring-disk in rotation for the dispensation of ten gallons of gasoline. The shaft 10 then makes one-half of one revolution before it is stopped. In the same manner, the vendor, by operating the push-button 61, energizes the solenoid 55 and starts the measuringdisk 36, which will be stopped after the shaft has made one-twentieth of one revolution and has dispensed one gallon of gasoline.

It will be seen from the foregoing description that although the apparatus is electrically started, thereafter it is mechanically controlled and stopped at the conclusion of one cycle of its operation, irrespective of the length of that cycle, which will depend upon the amount of gasoline to be dispensed.

If desired, the push-buttons may be supplemented or even replaced by coin-controlled switches such as shown herein, the term coin, as used, being designed to cover coins, tokens, or special plugs made on the .principle of the grooved keys of pin-tumbler locks. The coin-box 62 is formed with three vertical coin- passages 63, 64 and 65 opening at their lower ends into a till 66. The upper ends of these passages. terminate in conformed coin- slots 67, 68 and 69 formed. in the top plate 70 of the box 62. vNormally projecting into one wall of each of the passages 63, 64 and 65 I locate a spring-pressed reciprocating switch-plunger 71, which serves to connect the wires 72 and 73 when a suitable grooved-coin or token 74 is dropped into the slot 67, 68 or 69, as the case maybe.

Without going into the details of the wiring, it is obvious that when a.coin 74 falls through the passage 63, it closes the circuit of the solenoid 53. Similarly, the dropping of a coin through the passage (it-closes the circuit of the. solenoid 54, and also similarly the dropping of a coin through the passage 65 closes the circuit of the solenoid My invention has been shown and described as an improved electrically-started dispensing apparatus, which is its preferred form, but, obviously, the advantages procccding from its mechanical construction and organizationwould be present if manually started, as mightbe readily done by the lifting of the measuring-finger of the respective measuring-units by hand. -I would, therefore, have it. understood that my invention comprehends in its scope manual starting, if desired.
