Definitions

  • Tollberg Anorney-Sheiner & O'Connor ABSTRACT A wide price range, coin mechanism for a merchandising machine in which an electromechanical coin totalizer system responsive to the deposit of coins establishes credit and sets up change making circuits for giving up to four nickels in change over a range ofprices from St to $1.00 in S 6 steps while doing away with base price and price differential cam mechanisms of the prior art in which the range of prices is limited to the narrow range of differentials from the base price.
  • One object of our invention is to provide a change-making coin mechanism which permits goods to be sold over a wider range of prices than do coin mechanisms of the prior art.
  • Another object of our invention is to provide a change-making coin mechanism which is capable of giving change over a wide range of prices.
  • a further object of our invention is to provide a. wide price range, change-making coin mechanism which does not require the complicated price differential cam mechanisms of coin mechanisms of the prior art.
  • a still further object of our invention is to provide a wide price range, change-making coin mechanism which permits articles to be sold over a range of prices from St! to SLOO in 5 steps while being able to make up to 4 nickel: in change at each price.
  • our invention contemplate; the provision of a wide price range, change making coin mechanism in which an electromechanical coin totalizc'r establishes credits and sets up change-determining circuits for giving up to 4 niclteIs in change over a range of prices from 5! to $l.00 without the necessity of providing price ditferential cams of mechanisms of the prior art.
  • FIG. 1 is an elevation of our wide price range, change making coin mechanism.
  • FIG. 2 is an elevation of the other side of our change making coin mechanism.
  • FIG. 3 is a fragmentary elevation of a portion of our wide price range change making coin mechanism taken along the line 3-3 of FIG. 2 and drawn on an enlarged scale.
  • FIG. 4 is a fragmentary sectional view of a portion of our wide price range, change-making coin mechanism taken along the line 4-4 of FIG. 2 and drawn on an enlarged scale.
  • FIG. 5 is a schematic view of the electrical circuitry of our change making coin mechanism.
  • our coin mechanism indicated generally by the reference character 10 includes a frame 12 carrying a coin slot l4 through which deposited nickels, dimes and quarters pass to a coin separator and slug rejector assembly indicated by the reference character l6.
  • the slug rejector 16 may be of any suitable type known to the art such for example as that shown in (iabriclscn U.S. Pat. No. 2,975.8 from which all of the coins pass into and through a totalizcr assembly indicated generally by the reference character 18 such for example as that illustrated in Baker US. Pat. No. 2,996,l63.
  • Pin 28 extends through a slot 30 in the frame 12 to a position at which it supports a brush assembly driving rack 32 supported for vertical sliding movement in brackets 34 and 36 on the frame 12.
  • Rack 32 drives a pinion 38 carried by the shaft 40 of the brush assembly indicated schematically by the broken line outline 41 in FIG. 2.
  • the assembly 42 is driven through an angular displacement which is proportional to the aggregate of the sum in coins deposited in the machine.
  • the guide structure 44 normally holds the first nickel in a position at which it can be directed to a change coin supply tube 48 when the coins are accepted or alternatively it may be directed back to the escrow bucket 46 when the customer actuates the coin return to be described.
  • escrow bucket 46 may be actuated either to return all coins to the customer or to direct coins other than c first nickel to the cash box.
  • a lever 50 is positioned to direct the first nickel also to the escrow bucket. Since the construction and operation of the coin guide mechanism 44 and the escrow bucket structure 46 does not per se form part of our invention it will not be described in greater detail. The construction and operation is fully described in the Auerbach et al. application ro'ferred to hereinabove.
  • a customer may either make a purchase or he may have his coins returned.
  • the customer actuates a compound coin return link 52 in any suitable manner known to the art.
  • a pin 54 on the lower part of the link actuates a reset lever 56 to rotate in a counterclockwise direction about its pivot 58 as viewed in FIG. 2 to cause a leaf spring 60 thereon to move pin 28 upwardly to cancel the credit which had been established by the deposit of coins.
  • the first nickel is driven back towards the escrow bucket 46 and the bucket is operated in the manner described in the Aucrbach et al. application to return all coins to the customer.
  • a circuit to be described hereinafter including a brush of assembly 42 completes a circuit to an unlatching solenoid 62 to cause it to pivot an unlatching lever 64 in a counterclockwise direction as viewed in FIG. 2 around its pivot 66.
  • the lever first releases an arm 68 to cause a spring 70 to pivot the arm to a position at which a recess 72 therein locks out the coin return link 52.
  • a pin 82 pivotally connects the rod 80 to an arm 84 having a slot 86 which loosely supports arm 84 on a pin 88 on the frame I2.
  • a pin 90 connects the upper end of bent bar 80 to a Hat bar 92.
  • the electrical circuit of our coin mechanism sets up circuits for determining the vertical displacement of bar 92 and the corresponding movement of bar 80 proportional to the amount of change which must be given.
  • a U-shaped bracket 94 slidably supports a number of fingers 96, 98, I and I02 for movement between positions shown at which enlarged portions I04 of the fingers rest on the lower edges of lateral slots I06 provided in a flange 108 of the bracket 94.
  • Leaf springs I10 normally urge the fingers into engagement with the lower edges 106 of the slots.
  • the other ends of the finger are connected to the respective cores 112 of a plurality of solenoids II4, 116, N8 and I20.
  • Springs 122 normally urge the cores and the fingers to positions such as that shown in FIG. 4 whereat the enlarged portions of the fingers ride on the surfaces I06.
  • any one of the solenoids I14, I16, I18 and I20 it draws its associated finger to the left as viewed in FIGS. 2 and 4 until a reduced finger portion I24 falls into the corresponding notch I26 extending below surface I06 to lock the finger in that position.
  • the lower end of the change-determining bar 80 carries a projection I30 which extends through an opening I32 in the wall of frame I2 to a position at which it engages a pin 134 on a change-determining cam I36 of the change-dispensing mechanism indicated generally by the reference character I38 of our coin mechanism.
  • the mechanism I38 is shown and described in detail in Krakaucr ct al. US. Pat. No. 3,135,271. The only differences between our change dispensing mechanism and that shown in that patent are the particular manner in which the cam I36 is driven and the fact that an electrical motor drives our mechanism in a manner to be described rather than a manual operation. As is explained more fully in the Krakaucr et al. US. Pat. No.
  • the mechanism 138 includes a plurality of slides I40 positioned below the coin tube 48 and adopted selectively to be coupled to a driving slide I42 by a coupling link I44 to withdraw a predetermined number of nickels from the stack in tube 48 and to deliver them to a customer upon movement of slide 142 to the right.
  • An operating Icver I46 driven in a manner to be described is pivotally supported on a pin 148.
  • the distance through which the coupling link I44 moves in this direction and thus the number of slides engaged thereby is determined by the position of the change-determining cam I36.
  • This cam includes a plurality of steps I56 which selectively are positioned in the path of a stop I58 on the coupling link as the cam 136 is displaced in a counter clockwise direction as viewed in FIG. I in response to downward movement of bar as viewed in FIG. 2.
  • steps I56 which selectively are positioned in the path of a stop I58 on the coupling link as the cam 136 is displaced in a counter clockwise direction as viewed in FIG. I in response to downward movement of bar as viewed in FIG. 2.
  • a roller I78 on the arm engages a surface I80 of the reset arm to reset the coin totalizer I8.
  • Another roller or pin I82 on the upper end of arm I74 engages the undersurface of arm 84 to reset bars 92 and 80 and to permit bell crank 76 to relatch bar 80.
  • Arm I74 also carries a pin or roller 184 which extends through a slot 185 in the frame wall to a position between bifurcations I86 and 188 on the upper end of arm 146. It will be seen that as arm I74 oscillates pin 184 moves first to the right and then to the left as viewed in FIG. 2 or first to the left and then to the right as viewed in FIG. I. As a result, arm I46 first rotates in a counterclockwise and then in a clockwise direction as viewed in FIG. I. This movement of the arm 146 causes the first nickel to be delivered to the coin tube and actuates the bucket mechanism 46 to accept coins therein as described in detail in the Auerbach et al. application referred to hereinabove. The movement of arm 146 further actuatcs link 152 to position coupler 144 as determined by the position of cam 136 to engage the required number of slides I40 and then operates the slide driver 142 to deliver the required sum in change to the customer.
  • a pushbutton switch 200 is mounted on the frame 12.

Each contact 222 is connected in series with a respective selecting solenoid 224, 226, 228, 230 or 232 by means of an empty switch 234 associated with a particular machine section.
  • Respective pricing conductors 236 lead to the price board 206.
  • Price board 206 may be of any suitable type known to the art.
  • the arrangement is such that the conductors 236 may be on one side of the board while lines 204 are on the other side of the board with all of the lines 204 intersecting all of the conductors 236.
  • Any machine section may be set to dispense an article at any price within the range of prices provided by lines 204 merely by connecting its conductor 236 to a particular line 204 corresponding to the desired price at the point of intersection. This may be done in any convenient manner such as by inserting a conductive pin 238 through the board 206 at the point of intersection to connect a conductor 236 to a line 204.
  • section corresponding to solenoid 224 is set to sell articles at the section corresponding to solenoid 226 being set to sell at 80, the section corresponding to solenoid 228 to sell at 65, the section 230 being set to sell at 75, and the section corresponding to solenoid 232 as being set to sell at 35, While we have illustrated our mechanism in connection with only five merchandising units it will readily be appreciated that we might provide a great many more units selling articles of merchandise at other various prices.
  • winding 258 in series with switch I96 between conductors 240 and 246.
  • winding 258 When energized when the supply of coins is below a predetermined level winding 258 closes a normally open switch 260 to light a lamp 263 to indicate that the exact amount must be deposited to make a purchase. At that time winding 258 also opens a normally closed switch 262 to disable the change-making circuit in a manner to be described.
  • the mechanism must be able to give 2 nickels in change for articles selling at 40 or At all other prices the mechanism need be able to give only a single nickel in change. Our mechanism satisfies all of these conditions while at the same time preventing selection of an article at a price lower than or a price higher than the set price.
  • switch 196 closes to energize winding 258 to close switch 260 to light the exact change lamp 263 and to open switch 262 to disable the change making mechanism.
