To all whom it may concern:

Be it known that I, JAooB E. CorFEY, a citizen of the United States, residing at Casey, in the county of Clark and State of Illinois, have invented certain new and useful Improvements in Liquid-Dispensing Apparatus: and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others, skilled in the art to which it appertains to make and use the same, reference being had to they accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in apparatus for dispensing gasolene, coaloil and other liquids and consists in theprovision of a simple and 'eflicient apparatus of this nature having various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in which:

Figure l'is a central vertical sectional view showing parts of the apparatus in eleva tion. Fig. 2 is an enlarged detail view in elevation showing parts in difierent operative positions from that disclosed in Fig. 1. Fig. 3 is an enlarged detail in elevation of the mechanism in the lower part of the apparatus, and Fig. 4 is a sectional view on line 4-4 of Fig. 2.

Reference now being had to the details of the drawings by numeral, 1 designates a casing mounted upon a standard 2 and within which casing the operative parts of the apparatus are positioned. A frame 3 is mounted within the receptacle and 4 designates an exit pipe through which the liquid is dispensed and from which a vent pipe 5 rises vertically within the tank, and 6 designates an inlet pipe. A valve 7 is mounted upon a stem 8 and is adapted to regulate the inlet end of the pipe 4, said stem having a vertical play in the hollow bosses 9'which project from the standard 10. An angle lever 11 is pivotally. mounted upon a pin 12 other end to an apertured lug 17 upon the frame 3. A coin chute 18 registers with a slot 19 in the wall of the casing, as shown in lfig. 2 of the drawings, and the lower portion of the slot extends laterally and has an exit opening 20 through which the coins, desgnated by numeral 21, are adapted to fall lnto a coin receptacle 22. Two parallel pull bars, designated respectively by numerals 23 and shown in section in Fig. 4 of the drawings, and having a handle 23' pivotally connected thereto, are held spaced apart by a crosspiece 24 and a spring 25 is fastened at 26 to the frame 3 and its other end to the bars 23, normally holding the same in the position shown in Fig. 2. Said bars have a longitudinal movement in slots 27 formed in the walls of the casing of the coin slot and also through the frame 3 and the casing 1.

A boxing 28, shown in edge view in Fig.

-' 4:, has flanges 29 projecting from the upper and lower edges thereof and which are guided in slots in the walls of the slotted casing, and pins 30 project from said boxing and which are engaged by forked arms 31 of themembers 32, which is pivoted upon a pin 33, carried by the angle lever 11. Said member 32, it will be noted, has a recess 34: formed in its lower end, one side of which is open and afiording' means whereby the tilting movement of the member in one direction may be limited. A spring 35 is fastened to the member 32 and also to the stationary float stem 36 and is provided for the purpose of giving the member 32 a swinging movement independent of the lever 11 for the purpose of kicking the coin as the member swings in one direction, causing the coin to fall into thereceptacle beneath. u

A float 37 is mounted upon the stem 36 and till is provided with anti-friction rollers 38 upon its top and bottom which bear against the stem at points diametrically opposite, and 39 is a bracket member secured to the top of the float. An angle lever 4L0 is pivotally mounted upon a pin 41 carried by the standard 10 and has a short arm 42 which is pivoted to the link 43, which latter in turn is pivoted at 44 to the lever 11, thus forming a. toggle joint connection. A spring 45 is fastened at one end to the link 43 and its other end to the lever 11 and serves to cause the toggle joint to straighten or buckle when the angle lever 11 is tilted to the right to cause the valve 7 to open to allow the liquid to dispense. the buckling of the toggle joint serving to hold the valve open through the connections described. An adjusting screw 46 is mounted in a bracket arm 47 upon the standard and serves to adjust the swinging movement of the toggle joint in one direction. The long arm 48 of the lever 40' is positioned in the downward path of th float 37.

A valve 49, regulating the inlet valve 6, is mounted in a hollow boss 51 projecting from the standard 52, and 53 designates a lever with a slot 54 therein which receivesa pin 55 carried by the stem 50. Said lever 53 has a downwardly projecting arm 56 which is pivoted to a link 57 and which in turn is pivoted to the lower end of the lever 58 pivotally mounted upon apin 59 carried at the end of the lever 11. A spring 6O is fastened at one end to a lateral projection of the standard 52 and its other end bears against the lever 53 to the right of the standard 52. A lever 61 is pivotally mounted upon a pin 62 at the top of the standard 52 and has a rod 63 fastened to one arm which rod extends vertically through the frame 3 and carries a flanged disk 64 thereon, held upon the rod by means of a set screw 65. A

. collar 66 is also fastened by a set screw 67 to the rod 63 and limits its downward movement. A link 68 is pivotally connected to one arm of the lever 61 and its other end to a link 69 which in turn is pivoted to the upper end of the lever 58. A spring 70 is fastened at one end to the pivotal connections between the link 69 and lever 58 and its other end to the boss 9. .An adjusting screw 71 is mounted in the downwardly extending arm of the lever 53 and tends to adjust the swinging movements of the link 57 and lever 58 in one direction, forming a toggle joint connection.

A longitudinally movable bar 72 is mounted in apertures in said frame and a bracket arm 73 and is movable between the antifriction rollers 74 upon said bracket 73, and an arm 72 has a collar 72 thereon mounted upon the bar 72 and is held in adjusted position thereon through the medium of the set screw 72. Said arm 72 has a forked end positioned in the path of the bracketmember 39 upon the float 37. The upper portion of the bar 72 is curved as at 74, forming a cam edge which causes a lateral swinging movement to be imparted to the bar 72 as the curved portion passes by the edge of the slot through which the bar 72 passes. A pawl 81 is pivoted to the upper end of the bar 72 and its movement in one direction is limited by a pin 81*, said pawl being adapted to engage the flanged disk ()4 as the bar 72 is moved upward, carrying with it the disk and the bar 63.

Antifriction rollers 81 are mounted above and below the slot in the top of the frame through which the bar 72 passes and are adapted to bear against the opposite sides of said bar 72. A bar 82 is pivotally mounted upon a pin 83 upon a lug 84 of the frame 3 and is pivotally connected at its other end to a coin slot-closing slide 85 adapted to normally hold the coin slot closed until the supply of gasolene within the tank or receptacle 1s replenished. A rod 86 is pivotally connected at 87 to the bar 82 and has an elongated loop 88, shown in Fig. l of the drawings, and 89 is a finger engaging said loop 88 and projects from a collar 90 which is held in adjusted position upon the bar 7 2 by means of an adjusting screw 91. A bracket 92 is fastened to the casing 1 and is in the path of the bar 82 and is adapted to limit its upper movement.

The operation of my invention will be readily understood and is as follows: Assuming that the tank has a supply of liquid therein to be dispensed, the operator drops a coin in the slot and said coin runs down the inclined chute and rests upon the horizontally disposed ledge 18 and is positioned intermediate the bars 23 and between the crosspiece 24 and the boxing 28. The pull bars 23 are-then drawn out against the tension of the spring 25, causing the lever 11 to tilt and also the pivotal member 32 which is spring-pressed and which is pivoted to the lever 11. As the lever 11 tilts, the exit valve 7, through'its connection with said lever 11, will be raised from its seat and allow the liquid to dispense through the pipe 4. As the lever 11 tilts. the toggle link connections, consisting of the lever 40 and link 43, will assume the position shown in Fig. 3 of the drawings and be held in such position by the spring 45 which will hold the lever 11 at its farthest throw to the right and the valve 7 from its seat. As the lever tilts upon its pivot 12, it will be noted that the lever 58 carried by its short arm will be elevated and the link 57 will also be elevated and the spring 70 will cause the toggle link connection between the

levers

11 and 53 to assume the position shown in Fig. 3 of the drawings. As the lever 58 and link 57 are swinging from the position shown in Fig. 1 to the positions which they assume in Fig. 3, the rod 69, which connects the upper end of the lever 57 with the link 68, will cause the latter to swing against the lug 68 but without tilting the lever 61 in its movethe arm 72*, it will cause the latter and the the two bars.

ieoaaa ment. As the liquid is dispensed, the float 37 lowers upon the surface of the liquid and, when it comes in contact with the long arm 48 of the lever 40 and bears upon the same with sufiicient pressure to overcome the tension of the spring 45, the toggle joint connection between the

levers

40 and 11 will assume the positions shown in Fig. 1 of the drawings, and the exit valve will close and the inlet valve 49 will unseat, allowing the tank to be replenished with the liquid through the pipe 6. It will be noted that, immediately before the inlet valve is raised from its seat, the toggle joint between the lever 58 and link 57, assuming the positions shown in Fig. 3, will cause a rigid connec-, tion between the levers l1 and 53. The inlet 15 and the connections intermediate the same and the lever 53. As the float rises with the liquid in the tank as it is being refilled and when it comes in contact with bar 72 to be raised and the pawl 81', engaging the flanged disk 64, will impart an upward longitudinal movement to the bar 63, tilting the lever 61, and the toggle joint

intermediate the'levers

11 and 53 will break and the inlet "alve will seat through the in fluence of the spring 60. As the curved edge 74 of the bar 63 comes in contact with the antifriction rollers 81, a lateral swinging movement will be imparted to the'bar 72, suflicient to cause the pawl 81' to swing free of the disk 64 and, when the finger 89 .comes in contact with the upper end of the loop 88, an upward movement will be imparted to the rod 86and causing the bar 82 to swing up and with it the slide which covers the coin slot, thus opening the latter to allow another 'coin to be deposited in the.

aperture.

lltwill be noted that, after the pull bars 23 have been drawn totheir outer limits and released, the spring 35 connected to the member 32 will causethe same to swing upon its pivot and kick the coin out from between From the foregoing, it will be noted that the operation of my improved liquid dispensing apparatus is automatic in its action,

the valves being operated inthe mannershown for filling and allowing the tank to be dispensed and, by adjusting the member 72 upon the bar 72, the apparatus may be adapted to operate with different quantities of liquid contained within the tank. 1
