Definitions

  • the machine described in the patentin includes pivoted gate members blocking withdrawalfof bottles from dispensing stations and a coin release mechanism.
  • any one of the gates may be swung to open position in response to withdrawal of abottle. Swinging movement of a gate to open position causes a lock plate to slide a predetermined distance.
  • the lock plate is normally latched against sliding movement by means of a pivoted latch element having a nose portion extending into a slot in the plate.”
  • the latch and lock plate cooperate in such manner that a predetermined movement of the lock plate is necessary, before the latch is free to swing to a completely released position. This necessitates making the slot of such length that some movement of the plate is possible before it is arrested by the latch even though thernechanism is not released by a coin.
  • the improvement comprises the provision of Q a dog element pivotally mounted on the lock plate and having a portion which, in etfect, blocksone end of the slot in the lock plate soas to prevent unauthorized initial movement of the plate.
  • the dog element is adapted to provide an improved bottle vending mechanism arranged to prevent improper and unauthorized partial manipulation of the parts and thus prevent possible damage to the mechanism and unauthorized withdrawal of bottles therefrom.
  • FIG. 1 is a side elevational view of a fragmentary portion of a bottle vending machine incorporating the present invention
  • FIG. 2 is a vertical sectional view, on an enlarged scale, taken substantially along the line 2-72. of FIG. 1;
  • FIG. 3 is a perspective view of a portion of the mech anism incorporating the invention
  • Y FIGS. 4, 5, 6 and 7 are views similar to FIG. 2 but showing the parts in various relative positions during different portions of acycle of operationj
  • the vending machine is provided with suitable stationary frame elements 2 and 4. Sloping supply shelves (not shown sequentially feed bottles of beverage to dispensing platforms 6, upon which they rest in alignment with discharge openings in the machine frame. The bottles normally rest on the platform 6 with their necks extending to the right as seen in FIG. 1 but withdrawal of the bottles in that direction is prevented by gates 3, pivotally supported on the frame of the machine on horizontal pivot axes 10.
  • a link 12 is pivotally connected to the lower portion of each gate 8 and extends rearwa-rdly therefrom, being provided at its rear end with a roller or abutment 14 guided for movement along a "horizontal path.
  • a series of lock blocks 16 are provided to extend across the path of movement of the abutments 14 so that when one gate 8 is swung to its open position, its associated abutment 14 separates the adjacent lock blocks 16 to thus block sliding movement of all other abutments 14 associated with the other gates of the machine.
  • the pivot pins 18.. by which the links 12 are pivoted to the gates 8 extend.
  • Each slot 20 is provided with a flange 24 at its upper edge de fining a cam surface sloping downwardly and forwardly from each pin 18 when the gates are all in closed position.
  • Each slot 20 is of generally V-shape, having a vertical leg 26 extending downwardly from the pins 1 8.
  • the means for locking the plate 212 in its lowermost position comprises a pivoted latch 34 and a slot 36 in the lock plate 22.
  • the latch 34 has a nose portion 38 extending inmachine, at 40, and has a lower extension 42 closely adjacent one face of the lock plate 22.
  • lock plate 22 is in its lower position, the latch 34 cannot be swung to a release position since its lower extension will engage the plate 2.2 and prevent such release movement.
  • a spring 44 normally urges the latch 34 to its released position.
  • the solenoid 32 controls a slide 46 on which a blocking pin 48 is mounted. When the blocking pin 48 is in the upper position shown in FIG. 2, it holds the latch 34 is in its most counterclockwise position and actually holds the extension 42 spaced somewhat 23% I from the plate 22. Under such conditions the mechanism is locked, even though (before the present invention) the lock plate 22 was permitted to slide upwardly until its lower end 50 engaged the nose of the latch 34.
  • the edge 59 of the slot'36 must extend downwardly below the nose portion 38 so that the plate 22 may move upwardly sufficiently far to clear the extension 42 of the latch 34 when the mechanism is released for dispensing. Until the plate 22 reaches that upper position, the latch 34 could not swing to'a releasing position even if the blocking pin 48 were removed. It is this lost motion, or free sliding of the plate 22, that the present invention seeks to eliminate.
  • the solenoid 32 When a proper coin is deposited in the machine, the solenoid 32 is energized to pull slide 46 and blocking pin 48 downwardly away from the latch 34 whereupon the machine can be manipulated to dispense a bottle. The solenoid is then held in this position by a holding circuit until downward movement of plate 22 acautes the switch 30 wherein the solenoid 32 is deenergized and a spring 52 returns the slide 46 and blocking pin 48 to its uppermost position.
  • the dog 54 which is of generally channel shape in cross section (see FIG. 3), is provided with a dog element 54 pivoted thereto at'the lower end of the lock plate.
  • the dog 54 comprises a substantially flat plate portion 56 having opposed ears 58 pivotally mounted on a pin 60 carried by the lock plate 22.
  • a torsion spring '62 surrounds the pivot pin 60 and one end thereof engages the lowermost flange 64 of the plate 22 while its other end bears against an edge of one of the ears 58 to thereby urge the dog to swing in a direction to project its upper end toward the plate 22 in the region of the slot 36.
  • the upper edge portion 66 of the dog 54 constitutes a stop member engageable with the surface of the lock plate 22 to limit movement of the plate portion 56 under the influence of spring 62.
  • a tongue 68 extends from the edge'66 and is so dimensioned and proportioned that it extends freely into the slot 36, with its upper or free end portion closely adjacent the'lower edge of the nose portion 38 of latch 34.
  • the nose portion of the latch 34 is configured to define a cam edge 70 and a hook portion 72.
  • thehook portion 72 overlies the upper edge of the tongue 68 so that any effort to lift the plate 22 will result in the tongue 68 being engaged by the hook 72 and upward movement of the plate 22 is thereby arrested.
  • blocking pin 48 engages a cam surface 74 on the latch 34 and forces it to swing counter-clockwise from the position of FIG. 7v to the position of FIG. 2 wherein the parts are all in their locked position, as they were at the start of the cycle.
  • a vending machine having a plurality of article delivery stations, a movable gate member at each delivery station, and a slidable lock plate movable with any one of said gate members to block movement of all other gate members, the improvement comprising: a slot in said lock plate; a pivoted latch having a nose portion extending into said slot and spaced from the ends thereof;
  • a selectively retractable blocking member engaging said latch and normally preventing withdrawal of said nose portion from said slot;
  • a dog member pivoted to said lock plate and having a tongue portion projecting into said slot adjacent said nose portion to thereby prevent sliding movement of said lock plate; said dog being pivotally movable to swing said tongue out of said slot and spring means biasing said dog. to swing said tongue into said slot.
  • a slidable lock plate having an elongated slot therein adjacent one end, extending in the direction of plate movement; a latch pivoted intermediate its ends on an axis adjacent saidplate, said latch having a nose portion on one end thereof and extending into said slot intermediate the ends thereof when in gate 8 to open to bottle dispensing position.
