- a va vs 116 is adjustably fitted on the tube a means for carrying the plunger into the asoline is at the full level in the tank g 113 under the cover 42 so that when 1) the valve 116 effectively closes any s opening there may be between the tube 113 and cover 42 where the tube passes therethrough.
- the motor 19 may then function to operate the gasoline pump. As soon as the gasoline comes up to the predetermined level, the float 115 is raised sufiiciently to release the pull on the rod 103 of the switch 102 which it has held closed, so that the motor 19 is then stopped. .It is obvious that even though the switch 102 may close before the plunger 25 reaches its up rmost position, no gasoline will be pumpe until the plunger 25 does reach that position to permit closure of the switch 93.
- a further means to prevent unwarranted dispensing of gasoline is provided.
- a door 126 is provided to permit access to the pump and motor. When this door is 0 ened, a pawl 117 is carried under the en of the bar 28 b the link 118 pivotally interconnecting t e door and the pawl.

Like characters of reference indicate like parts throughout the several views in the drawings.
In the upper portion of a supporting structure 15, we mount a tank 16 here shown as made of metal though it may be made of any other suitable material such as glass. For the purpose of fully disclosing the invention in one particular form, the commodity to be vended will be hereinafter referred to as gasoline such as is commonly vended for automobile use. The gasoline is drawn from any suitable underground storage tank (not shown) throu h the pipe 17 by the rotarypump 18 driven y the electric motor 19 and discharged through the pipe 20 into the tank 16, the pipe 20 here shown as passing up through the bottom-of the tank 16 (Fig. 1.) and extending upward- Qly well toward, the top of the tank.
horizontal transverse section" on An overflow pipe 21 extends up through the bottom of the tank to terminate at a fixed level so that regardless of the amount of gasoline coming into the tank 16, the level of the asoline will be the top of the overflow pipe 21, which is preferably returned to the storage tank from which the pipe 17 leads.
A discharge pipe 22 also extends up through the bottom of the tank 16 and has its top end at the same level as that of the overflow pipe 21 The lower end of the discharge pipe 22 is interconnected with a flexible hose 23 which may be used to direct the discharged gasoline to any suitable 55 point, such as an automobile gasoline tank in the usual and well known customary manner.
A guide rod 24 is fixed to the base of the tank 16 and extends vertically 11 through and beyond the .top of the tan 16 to slidingly receive thereon the displacement plunger 25, which plunger has an upper tubular extension 26 slidingly guided over the rod 24: The plunger 25 is rigidly carried by the horizontal arm 27 which is secured the extension 26 whereby the plunger 25 may be adjusted vertically in relation thereto. The arm 27 is integrally attached to the upper end of the operating bar 28 which is carried in a vertical position between the outer side of the tank 16 and within the structure 15.
. The bar 28 extends downwardly below the tank 16 and has a pluralit ofteeth 29 cut in one edge to form a rac gear. The bar 28 passes through a bracket 30 which carries a pinion gear 31 in mesh with the rack gear teeth 29. A crank shaft 32 slidingly extends through the gear 31 and its short hollow shaft .34 and carries an operating crank 33 on the outer end externally of the structure 15, and has a dog 35 fixed to its inner end normally extended inwardly beyond the end of the shaft 34 by a compression spring 36. A dog 37 is fixed on the end of the shaft 34 whereby, by pulling outwardly on the crank shaft 32 the dog 35 mayengage with the dog 87,
turning of the crank 33 will then cause the gear 31 to turn and raise or lower the bar 28. Releasing the crank 33 permits the s ring 36 to disengage the dogs to permit t e bar normally to rop downwardly.
A weight 38 is attached to the end of the cable 39 which extendsu over around down from the=pulleys 40 an 41 and is secured to the arm 27. This weight is sufiiciently is such that the under side of the plunger ,25 is on a level with the tops of the pipes 121 and 22 so that any downward movement of the plunger will immediately start (lisplacing the gasoline to tend to cause it to overflow into the pipes 21 and 22.
Attached to the under side of the cover 42 is a bracket 45 in which is pivotally carried the lever 46, the lever 46 being mounted offs-center to have a longer arm toward the overflow pipe 21 and the shorter arm toward the discharge pipe 22 so that the lever 46 normally tends to have its longer end drop downward] to raise the shorter end corresponding y. To the outer end of the longer arm of the lever 46. is pivotally secured a hollow valve stem 47, to the lower end of which is affixed a valve head 48 adapted to seat in a conical seat formed in the upper end-.of the pipe 21. A hole 49 is drilled through the head below its rin of contact in the seat' so that there may ee free passage for air in from the top of the stem 47 and out through the hole 49 into the pipe 21 when the valve 48 is seated thereon.
A similar valve 50 is carried on a similar stem 51 pivotally suspended from the shorter end of t e lever 46, the valve 50 being adapted to be seated in the conical seat in the top end of the discharge pipe 22 (Fig. 1). An adjustable stop screw 52 is carried in the long arm of the lever 46 and is so adjusted as to have its lower end extend through the lever 46 to be contacted on the top side of the plunger 25 to hold the longer arm of the lever 46 upward sufliciently to tightly seat the valve 50 on the pipe 22 and lift the valve 48 from oil the pipe 21.
Now should the crank 33 be pushed in and turned to pull down the bar 28 so as to force the plunger 25 down into the gasoline, the
On the outer side of the collar 54 is fixed an upright arm 63'from which laterally extends a pin 64. A similar pin 65 projects from the side of the tongue 55 arallel to the pin 64. A cross member 66 o the structure 15 carries a bell crank 67 pivotally se cured thereto to have one leg hang substantiall '.normal'on the side of the pin 66 removed from the bar 28. The horizontall extended arm of the crank 67 is of suc length that it is normally below the in 65 when the bar 28 is up, and when the ar 28 is lowered will be contacted on its top side by the pin 65, be pushed down to rock back and swing over the top side of the pin 65, whereupon upward travel of the bar 28 will cause the low and t ereby rock the crank 67 to cause the vertical leg to strike the pin 66 and carr it and the ton e 55 therewith toward the ar 28 so that t -e end of the tongue 55 will have passed under the collar 54 by the time the crank 67 has been rocked sufiicient- 1y to rmit the pin 65 to pass around the end 0 the horizontal arm of the crank and release it.
It is now obvious that once the bar 28 has been lowered and raised to its top position, the tongue 55 entered under the collar 54 prevents further movement of the bar 28, and means for withdrawing the tongue 55 will now be described.
Three bars '68, 69 and 70 are slidingly mounted in the bracket 71 to slide perpendicularly from the front wall 61.
From the top side of the front end of each bar, a rod extends over the slide 56 and out through the wall 61 to receive the ull knobs 72, 73, 74 res tively thereon. mmediately above the obs are the slots 175, 17 6 and 177 of just the right proportions to receive a twenty-five cent piece, a fifty cent ieee, and a silver dollar respectively therein, and conductor tubes 76, 77, and 78 lead from the slots rearwardly and downwardly to terminate with but slight clearance over the respective bars 68 69, and 70. Slots 79, 80 and 81 corresponding in size to the respective coins are cut through from in 65 to contact the arm from be-.
securilto' the top sides of the bars 68, 69 and 70 to curve down and. forwardly to open from the front ends of the barsbelow the forwardly all three bars, and the bars are also notched from the under sides near the rear ends' to pass over the return lever 83 which is pivoted at one end and has a sprin 84 attached by one end to the free end- 0 the lever 83 and by its other end to a post out back of the bars, whereby the lever 83 normally retains the bars 68, 69 and 70 back against the stop strip 82, as in Figs. 7, 8, 9,-
and 10.
The bar 68 is proportioned so that when it is pulled forwardly by the knob 72the rear shoulder 85 of the notch over the strip 82 .will strike the strip before the front end of the bar strikes the slide 56 when the slide 56 is in itsinner position.
Releasing the knob 72 will permit the bar lever 83 to automatically return the bar 68 to its normal position which is such that a twenty-five cent piece coming down the conductor tube 76 w1ll drop into the slot 79 and roll against the slide 56'whereupon any pull on the knob 72 will cause the end of the bar 68 to press the twenty-five cent piece against I the slide 56, carry along the slide as the bar is moved, and thereby pull the tongue 55 out from under the. collar 54. "Upon releasing the knob .72, the bar 68 returns to its normal rear position and the coin drops by gravity into the money box 86, leaving the slide and tongue in the position indicated.
-The bar 28 may then be lowered by the crank 33. An adjustable stop 87' ispositioned on the bar 28above the collar 54 to have a down-turned leg that will strike on the tongue. 55 when the amount ofgasoline to be vended for twenty-five cents has been displaced by the proper travel of the bar 28. The intermediate bar 69 has the notch over the stop strip 82 proportioned so that the forward end of the bar when pulled ahead by the knob 73 maynot strike the slide 56 when no coin is therebetween,-but. is of'such length that when the fifty cent piece drops down the slide 56 is moved ahead or for wardly a total distance equal to that moved by the twenty-five cent piece in bar 68 plus the difference in diameters of the twentyfive and fifty cent pieces (Fig. '8), and the coin drops down throu h the opening 89upon release of the knob% 3. I
When the bar 69 is actuated as described,v
The bar is similarly formedto be operative with a. silver dollar pressed against the slide 56 to carry it ahead 9. distance farther than those reached by the two lesser coins, and a third adjustable stop 91 is'carried'on the bar 28. to strike the tongue 55 when moved to the' dollar position.
The tongue 55 andslide 56 are, as above.
indicated, returned after each outward movement to the inner normal position of the tongue 55 being under the collar'54: before again being moved out.
When any one of the bars 68, 69, or 70 are pulled ahead, the lever 83 is pulled ahead to come under the collar 54 from the back side so that when the tongue 55 has been Withdrawn from under the collar 51 and the particular bar is'normally held in the forward position, the bar 28 can not be lowered to permit any person to obtain gasoline thereby over the amount for which he had deposited his coin to originally withdraw the tongue 55. The bar 28 may be held in any position onceit is lowered by means of the screw 92 which may be run in against the edge of the'bar 28.
Unique means are provided to permit refilling of the tank 16 only whenthe plunger 25 has been returned to its uppermost position and the bar 28 locked against downward travel.
At one side at the lower end of the bar 28 is mounted an electric switch 93 (Figs. 1,5 and 6) which is normally held closed by the spring 91 which pulls the rod 95 toward the end of the bar 28 to hold the bar 96 in contact across the contacts 97 and '98. The end of the rod 95 is cut to slope downwardly and across under the end of the bar 28 so that downward movement of the bar 28 will cause the bar 28 to press the rod 95 back to overcome the spring 94 and carry the bar 96 away from the contacts 97 and 98. A wire 99 leads from the contact 98 to the motor 19 and a wire 100 leads from the other contact 97 out through the conduit 101 to any suitable source of electric current (not shown).
A second switch 102 is provided. This switch has the actuating rod 103 carrying the contact bar 104 across one end normally held out of contact with the two contacts 105 and 106 by the compression spring 107. A wire 108 leads from the motor 19 to the contact 105 and a wire 109 leads from the other contact 106 out through the conduit 101 to the source of current to complete the circuit including the switch 93 the motor 19 and the switch 102.
A cable 110 is fixed to the outer end of the switch rod 103 and passes up over,,
around and down from the pulleys 111 and 126 can not 112 in the top of the structure 15 and is attached to thetube 113 extendin slidingly through the cover 42. The tu 113 is slidinglyguided in a vertical direction b the rod 114 passing internally therethrougli and fixed to the bottom of the tank-16. T e tube 113 passes down to'within the tank 16 andadf'ustably carries thereon a float 115.
A va vs 116 is adjustably fitted on the tube a means for carrying the plunger into the asoline is at the full level in the tank g 113 under the cover 42 so that when 1) the valve 116 effectively closes any s opening there may be between the tube 113 and cover 42 where the tube passes therethrough.
When the plunger 25 is carried down into the gasoline, the level does not drop but raises, and the float 115 does not dro then, but when the plunger 25 is returne to its top ition the level of the gasoline drops and the float 115 drops accordingly to pull on the cable 110 and thereby close the switch 102, the switch 102 being usually closed thereby before the bar 28 has reached its upper limit of travel. As soon as the bar 28 comes up the switch 93 then closes,
and as both switches 93 and 102 are closed the motor 19 may then function to operate the gasoline pump. As soon as the gasoline comes up to the predetermined level, the float 115 is raised sufiiciently to release the pull on the rod 103 of the switch 102 which it has held closed, so that the motor 19 is then stopped. .It is obvious that even though the switch 102 may close before the plunger 25 reaches its up rmost position, no gasoline will be pumpe until the plunger 25 does reach that position to permit closure of the switch 93.
A further means to prevent unwarranted dispensing of gasoline is provided. A door 126 is provided to permit access to the pump and motor. When this door is 0 ened, a pawl 117 is carried under the en of the bar 28 b the link 118 pivotally interconnecting t e door and the pawl. The door be opened unless the bar 28 is position since the pawl will strike the bar 28 in any other position. our invention in the one at the top the edge 0 Having described form now best known to us it is obvious that many structural variations may be made without departing fromthe spirit of the invention, and we, therefore, do not desire to be limited to the precise form as shown and described norany more than may be required by the following claims.
