Definitions

  • the present invention is intended to alleviate this difficulty by providing a coin selector which can be easily modified to operate upon receipt of different coins or on any combination of difierent coins.
  • the only modifications which have to be made to the apparatus to accommodate different coins is to alter a coin receiving block and/or an escutcheon plate and possibly the height of a bridge. It need not be necessary to make all these modifications, the precise modifications to be made depending upon the size of the coins.
  • the apparatus also includes several checks for coins received by the apparatus in order to ensure that the coins are genuine. If any one of the received coins fails to satisfy any one of the checks then the coins are not accepted.
  • the elegant and compact construction of the apparatus enables it to be easily maintained.
  • the present invention provides apparatus for carrying out an operation or making an operation possible on receipt of one or more coins, which apparatus includes a movable coin receiving part for receiving at least one coin when in one position which coin receiving part is movable to a second operating position through coin checking means, and means for preventing the coin receiving part from being moved to the said second position if no coin has been received by the coin receiving part, the coin receiving part having two spaced abutments arranged to engage the edge of a received coin at two positions around the periphery of the coin so that a coin greater than a predetermined size projects above the coin receiving part a sufficient amount that the coin checking means prevents passage of the coin receiving part to the second operating position.
  • the coin checking means includes a third abutment and preferably the coin receiving part has two further spaced apart abutments to prevent a coin being received if its thickness is greater than a predetermined amount.
  • the abutments of the coin receiving part are formed by at least one slot and the coin checking means includes a second slot arranged to allow passage therethrough of a received coin of predetermined size placed in the slot of the coin receiving part and advantageously the slot of the coin receiving part is adapted to receive vertical coins.
  • the slot of the coin checking means is substantially at right angles to the longitudinal axis of the slot of the coin receiving part.
  • the coin receiving part is adapted to retain a received coin at least for the initial part of its movement from the said one to the said other position.
  • the means for preventing the coin receiving part from being moved to the said second position includes gripping means arranged to grip a grippable abutment means upon the coin receiving part which gripping means is depressed away from the abutment means upon the passage of a coin of the correct size.
  • the gripping means is spring biased towards the grippable abutment means.
  • the gripping means may be a pivotally mounted lever which has an inclined face to engage with the said gripping abutment means of the coin receiving part.
  • the apparatus preferably includes a bridge having wall members against which a coin of the predetermined size abuts and depresses the gripping means to allow passage of the coin receiving part.
  • a coin of less than the predetermined size does not abut against the wall members and depress the gripping means but allows the gripping means to grip the grippable abutment means of the coin receiving part to prevent the passage thereof.
  • the bridge has coin propulsion means to propel accepted coins from the apparatus and preferably this is an inclined abutment surface within the slot of the bridge.
  • the coin receiving part is a slide.
  • FIG. 1 is an exploded view of part of the apparatus
  • FIG. 2 is a sectional side view of the apparatus
  • FIG. 3 is a plan view of the apparatus
  • FIG. 4 is an underside view of the apparatus
  • FIG. 5 is a perspective view of part of the apparatus.
  • FIG. 6 is a sectional view along the lines BB of FIG. 2.
  • the apparatus shown in FIGS. 1 to 6 is for allowing a machine such as an automatic washing machine to be operated on receipt of a coin or coins from a person wishing to use the washing machine.
  • the apparatus has a manually operable slide 10 comprising a coin receiving metal block 11 which is screwed to a metal rectangular plate 12 by a screw 12a.
  • the block 11 has an integrally moulded handle 11a by which the slide 10 may be moved as will be hereinafter described.
  • the block 11 has three coin receiving slots 13, 14, 15 for receiving three different size coins which in the case of this example are a one shilling coin, a two shilling coin and a sixpenny coin respectively.
  • the slots 13, 14, 15 have a partly dished surface 18 to facilitate the insertion of coins.
  • the slide 10 is mounted for sliding movement in a metal frame 16 with a flat basepart 17 adapted to receive the slide 10 and an upright part 21.
  • Screwed to the upright part 21 by screws 20 is an escutcheon plate 19.
  • the escutcheon plate 19 is provided with three slots 22, 23, 24 as shown in FIG. 1.
  • the three slots 22, 23, 24 are in line with the three coin receiving slots l3, l4, 15.
  • the base part 17 and the folded over edges of the frame 16 constrain the slide 10 so that it may slide between a leftward position, in which the slide is shown in FIGS. 2'to 4, and a rightward position.
  • Leftward movement of the slide 10 is limited by a stop 51 which projects above the body of the block 11 and which abuts against the escutcheon plate 19.
  • Rightward movement of the slide is against the bias of a spring 52 fastened between a post 54 on the frame 16 and the end of the plate 12 at 55.
  • the rightward movement is limited by the end stops 56 which abut against the ends of the block 1 1.
  • the part of the apparatus to the right of the upright part 21 as seen for example in FIG. 2 is inside the machine and normally inaccessible and the part of the apparatus to the left of the upright part 21 is outside and accessible.
  • the coin receiving block 11 can receive coins only when the slide 10 is in its leftward position.
  • the slide 10 has suitable means such as a cam 25 or the like screwed to the end of the plate 12 at its right-hand end by screws 26 for operating a washing machine when the slide is moved to a rightward position.
  • a person wishing to operate the washing machine inserts the appropriate coins as required into the coin receiving slots l3, 14, 15 when the slide 10 is in its leftward position and then pushes the handle 11a of the slide 10 to its rightward position in which the slide operates the washing machine. As will be described hereinafter movement of the slide to its rightward position is prevented if the coins do not satisfy certain checks.
  • the sides of the slot 14 form two abutments 27 and 28 (see FIG. 3) which are spaced apart by a distance slightly greater than the diameter of a genuine coin.
  • the plate 12 has an opening 29 in it below the slot 14 so that when a genuine coin is received by the slot 14 the lower part of the edge of the coin will rest on the base part 17.
  • the slot 23 in the escutcheon plate 19 at 90 to the slot 14 forms a third abutment 30 spaced above the base part 17 by an appropriate distance.
  • the slots 14 and 23 are in line so that when a genuine coin has been received in the slot 14 and the slide is then moved to the right the coin will pass through the slot 23 the coin being retained as it moves by being supported on the base part 17.
  • the two abutments 27 and 28 will engage the edge of the received coin at two positions around the periphery of the coin and cause the coin to project above the slide 10 a distance greater than that of the height of the abutment 30 above the slide 10, so that if any attempt is made to move the slide 10 to its rightward position the top edge of the coin will 30 and prevent such movement.
  • the apparatus operates in precisely the same way to prevent the slide being moved rightward if a coin with a diameter substantially greater than that of a genuine coin is received by the slots 13, in the block 11, the slots 22, 24 respectively providing the third abutments to prevent the passage of coins having a diameter greater than that of the predetermined amount.
  • the sides of the slot 14 form two further abutments 31 and 32 which are spaced apart by a distance slightly greater than the thickness of a genuine coin. These two abutments will prevent a counterfeit coin being received at all by the slot 14 if the thickness of the coin is greater than their spacing.
  • the block 12 operates in precisely the same way to reject a coin if its thickness is substantially greater than that of the slots l3, l5.
  • This means comprises three levers 33 which are pivotally mounted upon a pivot shaft 34.
  • a leaf spring 38 is attached to the frame 16 by screws 39, the leaf spring acting to urge the levers 33 through an opening 57 in the frame against the plate 12.
  • the levers 33 have inclined gripping faces 35 which may engage locking keys 36a screwed to the block 11 by screw 12b on the underside of block 11.
  • the levers 33 are of a general T-shaped section, with the center member 37 projecting upwards towards the plate 12.
  • levers 33 are not depressed. Since levers 33 are urged upwards by the leaf spring 38, the gripping faces 35 are engaged with locking abutments 36a, said levers 33 being lowered by the inclined faces of abutments 36 on the block 11 to the undersurface of the block 11 thus preventing further movement of the slide to the right. Also since the face 35 of the lever 33 is inclined then increasing the force in order to try to compel the slide to move to the right in an attempt to start the washing machine for the insertion of no coins causes more of the face of the lever to be engaged with the locking keys 36a so more firmly engaging the levers 33 and the locking keys 36a.
  • a further device is incorporated into the apparatus in order to enable coins which are too narrow or otherwise of the wrong shape to not be accepted even through the coins may be of the correct diameter to have passed the checks provided by slots 13-15, 22-24.
  • the further device is a bridge 45.
  • the bridge 45 is secured to the frame 16 by two screws 46 (see FIG. 3).
  • the bridge has three rectangular slots 47, 48, 49 in line with the slots l3, 14, 15 in the block 11.
  • Within each of the slots 47, 48, 49 and slightly spaced from the entrance are wall members 50.
  • At the rear of the bridge is an inclined surface 58.
  • the edge of the coin would abut against the inclined surface 58 before contacting the depressing the lever 33 so that further movement of the slide to the right would be prevented.
  • the height of the bridge 45 above the frame may be varied by the inclusion of shims (not shown) between the bridge and the frame 16 so that the distance between the wall members and the levers may be altered and hence the thickness at which coins are rejected may be altered.
  • the apparatus can be simply modified to operate on any combination of coins or even if no coins are inserted, by the use of one or more blanking plates 40 (see FIG. 5).
  • the blanking plate 40 has two arms 41 and 42 which fit into slots (not shown) on the underside of the block 1 l.
  • the projecting part 43 projects into the appropriate slot and prevents the insertion of coins into that slot.
  • the lower projecting part 44 is adapted to simulate a genuine coin so that when the slide 10 is moved to the right the blanking plate 40 engages the appropriate center member 37 of the lever 33 and depresses the lever to allow the slide 10 to continue to move to the right. It will be appreciated that blanking plates may be inserted into the block 11 so that the block 11 may be arranged to work on any combination of coins, the vacant slots being filled by blanking plates.
  • a nonretum means is included within the apparatus to prevent the slide being returned to its original starting position without having first been moved to a rightward position in which the slide operates the washing machine.
  • the nonreturn means comprises two pivotally mounted ratchet arms 60, one on each side of the frame 16.
  • the arms 60 are spring biased by springs 61 to have the apex of the arms 60 projecting downwards to engage spaces 62 between teeth 63 in the plate 12.
  • the spaces 62 and the arms 60 engage substantially as the received coins fall into the cash box to prevent the slide 10 being returned.
  • the slide 10 then has to be pushed fully to the right to engage the cam 25 with the washing machine when the arm 60, having moved over the teeth 63, is received by the larger space 64.
  • the inclination of the arm 60 may now be reversed to facilitate the return of the slide to the original leftward starting position in readiness for a further operation.
  • a magnet may also be positioned within the apparatus. This magnet would cause any coin which included ferromagnetic material (i.e. is counterfeit) to jam in the apparatus and prevent further rightward movement of the slide 10.
  • a device for preventing movement of the slide to its rightward position if a received coin has a hole in it may comprise a pivoted lever for each coin, the lever being arranged so that its end presses'against the face of the coin at some stage as the slide moves from its leftward to its rightward position.
  • the lever carries a stop and is arranged so that if there is a hole in the coin the end of the lever will enter this hole and cause the stop to operate to prevent further rightward movement of the slide.
  • the above apparatus can readily be adapted for use with other coins. This adaptation is carried out by replacing the coin receiving block 11 and/or the escutcheon plate 19 and possibly altering the height of the bridge 45 by shims as aforementioned.
  • coin freed apparatus comprising a coin receiving part movable .between first and second operating positions having coin receiving means for receiving at least one coin when in said first operating position, coin checking means positioned between the first and second operating positions, means for preventing movement of the coin receiving part from the first to the second operating position, said preventing means having upon the coin receiving part a grippable abutment member, said means including gripping means for gripping the grippable abutment member to thereby provide a first engageable position to prevent movement of the coin receiving part from the first operating position to the said second operating position and a second disengageable position to permit movement of the coin receiving part from the first operating position to the second operating position, said coin receiving part having two abutments spaced apart a distance slightly greater than the diameter of a coin of predetermined size, whereby a coin of greater than a predetermined diameter engages the edges of the spaced abutments and projects above the coin receiving part to engage a third abutment upon the coin checking means to prevent passage of the coin
  • the gripping means is a spring biased pivotally mounted lever which has'an inclined face to engage the grippable abutment means of the coin receiving part.
  • gripping means has an inclined face on each side of the center member.
  • a coin receiving part movable between first and second operating positions having a first slot for receiving at least one coin when in said first operating position
  • coin checking means having a second slot positioned between the first and second operating positions
  • said preventing means having upon the coin receiving part a grippable abutment member said means including gripping means for gripping the grippable abutment member to thereby provide a first engageable position to prevent movement of the coin receiving part from the first operating position to the second operating position and a second disengageable position to permit movement of the coin receiving part from the first operating position to the second operating position
  • said first slot of the coin receiving part having two abutments spaced apart a distance slightly greater than the diameter of a coin of predetermined size, whereby a coin of greater than a predetermined diameter engages the edges of the spaced abutments and projects above the receiving part to engage a third abutment upon the coin checking means to prevent
  • the gripping means contains a center member, coins of the correct predetermined size on movement to the first to the second operating position contacting said center member to depress said gripping means, the gripping means having an inclined face on each side of the center member to engage said grippable abutment means of the coin receiving part.
