HERBERT L. HAIGHT, OF LANSING, MICHIGAN.

l i VENDING-MCHINE.

Be itknown that I, HERBERT Il. Haroii'r, a `citizen of the United States, residing at Lansing, inthe county of Ingham and State of Michigan, have invented certain new and Auseful Iniprovementsxin Veudin -Machines,

of which the following isa speci cation.

My invention relates to'. vending machines and has particular reference to machines ofA A further'ob]ect of this invention is to liquids, .such as provide means ofthe above mentioned char! acter, which are primarily operated by a single crank or the like, the remaining elements thereofl being 4actuated by the movement of the crank and operating automatically.

A further obje-ct of my"iiivention 4is .to provide means to positively lock'the-pump. operating elements of the apparatus. againstV rotation before the proper coin inserted, such elements being automatically released* 'upon the insertion of the coin and a slight- 35 movement of the crank nd associated elements. .f Y

A further object of the, invention is' to provide means to return th'e coin to the operator in the event that the apparatus does not contain a. sufficient amount of gasolene:

or the like.

' Other objects and advantages of this invention will be apparent during the coursev of the following description'.

thereof being shown in section, and, Fig. 5 is a sectional view through theliqud fuel hold- Y* 'ing'tank or receptacle, the elements disposed therein beingvshown in section,

In the drawings, wherein is illustrated preferred embodiment of my invention, the

numeral 6 designatesa casing or shell, of anv well known or preferred type, Within which are arranged the different operating elements of the apparatus,'so 'that the sainel cannot be vtampered with.'

Rigidly mounted within the shell 6, nearl and spaced from the upper endthereof, is a horizonaal support or base 7, as Shown. Rigidly mounted upon this base 7 are spaced upstanding `bearings V8, within which is rotatably mounted an operating shaft 9. This operating shaft extends 'outwardlyfbeyond the shell 6 and is' provided at its free eno `with a handle or crank 10, rigid1y connected ltherewith. The operating shaft @cari-.ies a 'ratchet wheel 11, rigidly mounted vvvvthereon.

[This ratchet Wheel is provided Witha later'- `fa'lly extending hub or sleeve 12,rigidly com nected therewith and :preferably-cast inte' hub 15, forming a partfof a sinallgar 16,

which is rotatably mounted upon the open' `ating shaft 9. The teeth'13 and 14 arepref- 'erablyo arra' l l Thelma-12 vis pro-' vided Yat its end vwith 13, to l-en, 2;age with teeth 14 formedi'iponfthe end of a ed that the hub A1,2 may be lrevolution before the teeth 33 Vwill engage` V-the teeth 14 to effect the rdta .on of the' hub "15 in the same directionlr' itis thus seen that the teeth' 13 and 14 form a 4lost motionconneotion or clutch between the hubs 1? and 15. The hub 1Q. carriesan upstandir'g lpost 17 andthe huh lo .in opstanding post 18, which are connected L a Suit-ably stili retractile coil spring i9, thefunction vof' 1which is to return the huh .'i to its normal position when released :i the teeth 13 and 14 will be properly spinal, I'or'allowing the hub 12 to be turned or'substantially one-fourth of a revolution before turning the hub 15, as above stated.

Rigidly mounted upon 'thebase 7 .are Aupsl-:inding spaced beariiigs 20, through which is liournaled a rotatg-vllle shaft 21. This .shaft 21 has a la rife geatfx feel 22 rigidly mounted thereon chiel vpeina'ncntly engages the small gear Wheel 16, as shown. Rigidly con-` nected vvwith lme end of the rotatable shaft 2t is a crank-disk 23,.which operates within an opening 24 formed in the base 7, as shown. l

Means are provided Vto normally lock the large 1gear wheel or pinion 22 against rotation, comprising a movable or reciprocatory bolt 25,A provided at its forward end with a tooth 26 to engage between the teeth of the gear wheel or pinion 22. The reciprocatory bolt 25 operates within a stationary guide bracket 27, rigidly mounted upon the base 7 as shown. Suitably connected with the reciprocatory bolt 25 is a curved rod or arm 28,connected at its opposite end with a head 29, carried by a reciprocatory rod or bolt 30. The rod or bolt 30 operates through a horizontal guide bracket 31, which 1s rigidly mounted u on a support 32, fixed upon the base 7. The reciprocatory rod or bolt 3() and the arm or rod 28 are Aadapted to be moved longitudinally simultaneously in the same direction, the same being in effect a continuous rod. Connected with the forJ ward or free end of the rod or bolt 30 is a retractile coil spring 33, which is attached t0 the shell 6 or other fixed support. The spring 33 normally holds the rod or bolt 30 in a forward position with the head 29 enwaging the guide bracket 31, as shown in ig. 1. y

The head 29 is provided upon its lower side with a longitudinal slot 34, for receiving the teeth of the ratchet wheel 11. This head is also provided with a vertical coin `slot 35, which leads into the slt 34. It is thus seen that when a suitable coin is inserted within the slot 35, the same lwill engage with the teeth of the ratchet Wheel 1l, which upon being turned in the direction of the arrow will move the head 29 andassociated elements longitudinally in the same direction, whereby the tooth 26 of the bolt 25 will disengage the teeth of the large gear wheel 22.

The rod or bolt 30 is provided upon its upper surface with a recess or notch 36, to be moved adjacent to and receive the end of a dog or pawl 37, upon the longitudinal movement of the same in one direction. Thel free end- .of this dog or pawl operates through angpening 38'formedl in the guide bracket 31, the same normally slidably engaging the rod or bolt 30. This dog or pawl 37 is pivoted, as shown at 39 upon fixed ears or brackets 40. v'

Suitably mounted 'within the'upper end of the shell 6 is a dispensing tank or receptacle 41 having connection at its lower end with a depending sup'ply pipe 42, as shown. The numeral 43 designates a tubular post mounted within the dispensing tank 41, as shown. Extending longitudinally through the tubular post 43 is a connecting rod 44, the lower end of which is forked and straddles the dog or pawl 37 and is pivotally connected therewith, as shown at 45.' Connected with the upper end of the tubular post 43 is a horizontal support or bar 46, upon which is rigidly mounted an upstanding ear or bracket 47. Pivotally connected with the upper end of this bracket 47, as shown at 48, is a vertically swinging lever 49, having pivotal connection with the upper fork end .of the connecting rod 44, as shown at 50. Rigidly connected with one end of the vertically swinging lever `49 and preferably formed integral therewith is an approximately U-shaped bracket 51, supporting a screw-threaded rod 52, rigidly attached thereto.

VThe numeral 53 designates a float-ball, which is longitudinally movably mounted u'pon'the Avertical rod 52 and held upon the saine in adjustment at a desired position by nuts 54, disposed above and below the same, as shown. Adjustably mounted upon the oppositeend of the lever 49 is a counterweight 55, which is clamped in adjustment at a desired position upon said lever by means of a clamping screw 56 or the like. It is thus seen that when the bolt or rod 30 is longitudinally moved to the right so that the free en'd of the Clo-g or pawl 37 will enter the nptch 36, upon the supply of the proper amount of liquid to the dis ensing tank 41 (b means to be hereina er described), the float-ball 53 will be elevated, whereby theflever 49 will have its right end swung upwardly, to move the rod 44 upwardly. Upon this upward movement of the rod 44 the dog or pawl 37 iselevated to release the boltor rod 30, the spring 33u at onceA returning the same to its normal position.

Connected with the lower portion or end of the dispensingv tank 41 vis an outlet or discharge pipe 57, which extends outwardly beyond the shell 6 and is preferably connected with thel hosel 58 or other suitable conduit. Connected in the outlet pipe 57 is a valvestructure 59 of any well known or preferred type, the valve of which (not shown), is operated by a stem 60, passing through a fixed ide bracket 61. Rigidly connected with t e outer end of the stem 60 is a depending crank 62, having pivotal connectionwith a link 63, which is in turn pivotallyl connected with an upstanding finger 64. This finger is provided at its lower end with an open head, for receiving the free end of the rod or bolt 30, the same being clamped thereon by a screw 65. When the rod or bolt 30 is in itsnormal position, as shown in Figyl, the valve structure 59 is open to allow of the escape of the liquid from the tank 41'but when the rod 30 is moved longitudinally to the right so that the end of the dog or awl 37 enters the ated by the finger 64, link 63 and depending crank 62, as is obvious. It is to be understood that any suitable form of valve may be connected in the ipe 57.

Disposed below t e base 7 is pumping means, comprising a stationary upstanding cylinder 66, within which is mounted a piston 67. Pivotally connected with this piston is a dependin pitman 68, having pivotal connection witg the crank-disk 23, as shown at 69. The lower end of the cylinder 66 is connected with a T-coupling 70, which is connected with a depending pie 71 and the pipe 42. The pipe 42 has a c eck valve .g 72 connected therewith, as shown. The pipe 71 exten'ds downwardly and leads into a liquid fuel holdinr tank or receptacle 73, as clearly shown in hg.. 5. The pipe 71 has a check valve 74 connected therewith.

Disposed within the tank 73 is a vertical pipe 75, within' which is mounted a oat 76. Connected with this float is an opstanding rod 77, pivotally connected at its up er end with a horizontal lever 78, which is pivotally' mounted, as shown at 79, upon a fixed support 80. g

The numeral 81 designates a coin chute, which is connected at its outerfend with the shell 6 and at its lower end with the guide bracket 31, as shown. This coin chutecond ucts the coin to the slot 35. The coin chuter 81 comprises an upwardly swinging secl tion 82, pivoted, as shown at 83. The section 82 is pivotally connected with a rod 84, which extends downwardly and is pivotally connected with one end of the lever 78. Disposed below the coin chute section 82 is a housing 85, to deliver-the return coin into a catching receptacle 86, through an opening 87. 1t is thus seen that when the liquid fuel held within the tank 73 falls below a certain level, the float 76 will descend, which through the connecting ,means will elevate the chute section 82, providing an opening. whereby the coin vill fall into the housing 85 and return to the operator. Disposed forwardly of and near the ratchet wheel 1l is a coin catching receptacle 86, into which the coin falls upon the proper rotation of the ratchet wheel and after the coin has fulfilled its flif'tion.

The operation of the machine is as follows :MA coin 70fL is inserted into the outer end of the chute 81, and is conducted thereby into the slot 35 of the head 29, to engage lthe teeth of the ratchet wheel *11, forming detachable connecting means between the head and the ratchet wheel. The operator now turns the handle 10 clock-wise for rotating the ratchet wheel l1 in the direction of the arrow, as shown in Fig. 1. When the handle l0 is first turned, that is before thc same has been turned for substantially a quarter of a revolution, the shaft 9 being rigidly connected with the ratchet wheel 11 `the right. It is 4and extension 12 will primarily turn the `when the shaft 9 has been turned for a quarter of a revolution. Upon the partial rotation of the ratchet'wheel 11 while the gear wheel 16 is stationary, as above stated, the head 29 and arm 28 are moved longitudinally to the right to withdraw the tooth 26 from between the teeth of the large gear wheel 22, such arm 28 being held 1n this position by the free end of the pawl or dog entering the opening or notch 36 of the rod or bolt 30, carried by the head 29. When the rod or bolt 30 is moved to the right so thatv the end of the pawl 37 enters the recess 35,' the coin within the slot of the head 29 opeupies a position at or near one side of the ratchet wheel, whereby the tooth which en gages the coin will now tend to move the same downwardly for discharging it from the slot, the same being connected within the receptacle 86. Attention is called to the fact that as the pawl 37is now holding the rod or bolt 30 against returning movement, the tension of thel spring 33 will be practically emove'd from the coin. in practice it has een found that no difiiculty is experienced in operating the machine due tothe failure of the coin to drop or disengage the ratchet wheel, but if the same should stick.7-it is obvious that the same may be readily released, after the pawl 37 has entered the recess 36, by turning the. crank shaft 9 slightly in a reverse direction, it being remembered that the coin is now located near or upon `one side of the ratchet wheel. the same falling within the receptacle 86. The' valve structure 59 is closed upon the movement of the rod or bolt 3() to thus seen that the large pinion 22 is released and the lock-ing means therefor 'will be held out of engagement therewith, until a proper amount of the gasolene or the like has been pumped into the dispensing tank 41. The crank .l0 is now rotated freely in the same direction` the tif-cth 13 engaging the teeth 14, whereby the small gear 16 is locked to the shaft 9 for rotation therewith. `The small gear 16 rotates ille large gear wheel 22, which in turn rotates the shaft 21.v This shaft rotates the crank disk 23, which causes the piston 67 (see Fig. 4), to be reciprocated, for umping the gasolene or the like from t e tank 73, through pipe 42 into the dispensing tank 41. This pumping action is continued until just the correct amount of the gasolene or the like has been pumped into the dispensing tank 41, when the float-ball 53 will be suiiiciently elevated to move the ref' 44 upwardly. whereby the free end of til. dog or pawlpis withdrawn from the opening or notch 3,6. When this takes place the spring 33 at once moves the rod or bolt 30, head 29, and arm 28 to the left into their normal position. The valve structure 59 is now opened and the bolt 25 returned to engagement with the gear wheel 22 to prevent rotation of the same. The gasolene or the like will now discharge through the pipe 57. The small gear wheel 16 engaging the large ear wheel 22, is now held against rotation. hen the crank or handle 10 is released, the gear wheel 16 being relatively stationary, as above stated, the spring 1 9 will turn the ratchet Wheel 1l andI associated elements counter-clock-wise so that the teeth 13 and 14 will be spaced for substantially a quarter of a revolutlon.' When the level of the gasolene within the tank 73 drops below a certain point, the fioat 76 descends carrying with it the rod 77, which swings the lever 78. This movement of the lever 78 moves the link or rod 84 upwardly to swing the coin chute section S2 upwardly` whereby the coin is returned to the operator.
