  • the present invention relates in general to a coin slide assembly for use in connection with coincontrolled devices, such as machines which vend either goods or services.
  • the present invention provides a coin slide assembly which is relatively simple in, construction and which can be easily modified by replacement of the coin slide and by making a few adjustments to take different coin denominations and combinations thereof.
  • a lower assembly and an upper assembly releasably connected to the lower assembly and defining therewith a longitudinal guide passage.
  • the coin slide which is interchangeable for different coins, is disposed for reciprocable movement in the guide passage. Operation of the coin-controlled device without inserting the proper coin or coins into the coin slide is prevented by a blocking means having parts which are supported preferably by the lower assembly, but can be supported by either one of the upper and lower assemblies, or by both of them.
  • the blocking means is disposed to normally block the movement of the coin slide beyond a preset limit position by inserting an obstruction into the guide passage in the absence of the proper coin or combination of coins in the coin slide.
  • the blocking means is responsive to the presence of the proper coin or combination of coins to remove the obstruction from the guide passage and thereby allow movement of the coin slide beyond the blocking limit to a position for activating the coin-controlled device.
  • the invention is applicable to coin slides which carry multiple coins of the same or different denominations, as well as to coin slides which'carry only a single coin.
  • the blocking means has for each coin receiver of the coin slide a lever which is engaged by the coin and pivotally displaced thereby. This lever is coupled to a spring biased obstructor element such that when the proper coin engages the lever, the pivotal displacement thereof will be sufficient to withdraw the obstructor element from the guide passage.

  • FIG. 13 is a partial plan view of the lower assembly, similar to that shown by FIG. 7, but illustrating the operation of the coin sensing levers of the blocking means.
  • FIG. 14 is an exploded perspective view of a typical coin sensing lever used in the coin slide assembly of the invention.
  • FIGS. 1 land 12 there is shown a coin slide assembly 10 that can be regarded as having three easily separable major components, namely a lower assembly 11, an upper assembly 12 and an interchangeable coin slide 13 shown in more detail by FIGS. 4-6.
  • the upper and lower assemblies 11' and 12 are releasably connected together by a plurality of screws 15 and define betweentheir inside faces 17 and 18 respectively, a longitudinal guide passage in which coin slide 13 is disposed for reciprocable movement.
  • the coin slide 13 is a double coin type, having two coin receiving openings 19 and 20 disposed in side-by-side parallel relation. It is to be understood that a'coinslide not shown) having a single coin opening could be substituted for the double coin type shown, with the elimination of corresponding parts associated with handling one of the coins.
  • the invention provides blocking means to prevent movement of the coin slide 13 beyond a preset forward limit posi tion without the proper combinationof coins inserted into openings 19 and 20.
  • blocking means are providedto limit the forward movement of the coin slide so that it cannot be pushed to activate the device without deposit of proper coins.
  • the type of blocking means employed is one that has a spring 21 disposed to normally urge a pair of slidable obstructor blocks 22 and 23 into positions where they each obstruct a corresponding longitudinal groove 24, 25 in lower assembly 11, as can be seen from FIGS. 7 and 11.
  • the guide passage configuration defined by the upper and lower assemblies 11 and 12 has a flat portion extending widthwise commensurate with the width of the coin slide 13, and the longitudinal grooves 24, 25 that extend transversely to the flat portion of the guide passage are in effect other portions thereof.
  • Coin slide 13 has a flat portion 26 disposed for insertion into the flat portion of the guide passage, and a pair of laterally spaced rails 27 extending from the underside of portion 26. Each rail 27 is disposed for insertion into a corresponding groove 24, 25 and to travel therealong. Located ahead of rails 27 and aligned therewith for travel in grooves 24, 25 are fingers 28. Behind rails 27 and aligned therewith are coin pushers 29 and guide pins 30 which also travel in grooves 24, 25 with the coin slide 13.
  • the coin receiving openings 19 and 20 are aligned generally concentric with coin openings 19A, 20A respectively in the apron 31 of upper assembly 11, and fingers 28 engage against the outer endwise facing sides of blocks 22 and 23 to prevent further pullout of coin slide 13.
  • coin slide 13 can be pushed forward to a preset limit position established by the engagement of either one or both blocks 22, 23 with the forward edge of rails 27. If only one coin is inserted, limiting of coin slide 13 forward movement is effected by the block 22, 23 associated with the blocking control for the other, missing coin, whereas if no coins are inserted, both blocks 22, 23 effect limiting of coin slide 13 forward movement.
  • the guides 39 and 40 have wrap-around ears which serve to prevent the coin 32, 33 from jumping up as it is pushed through the deposit slot 38.
  • guide 40 is displaced laterally outward and thereby pivots lever 41 such that the forward end 42 thereof is swung inwardly pressing against the head of a screw 43 received in a corresponding block 22, 23 and secured by a nylon insert 45.
  • This causes the block 22, 23 to be pushed against spring 21 into the guide channel 44 and removes the obstruction normally presented by such block 22, 23 in the groove 24, 25.
  • coin slide 13 When both blocks 22, 23 are withdrawn out of obstructing grooves 24, 25, coin slide 13 can be pushed forward to its extreme limit position that is established by the engagement of projections 46 on rails 27 with barriers 47 extending across grooves 24, 25 at guide channel 44. These barriers 47 offer no interference to the portions of rails 27 forward of projections 46. At this extreme forward limit position, the coin slide 13 commonly effects closure of a switch (not shown) to activate the coin-controlled device, and threaded holes 48 are provided at the end of coin slide 13 to facilitate attachment thereto of some other part (not shown) as might be used for activation purposes.
  • Coin slide 13 is biased by a spring 49 to return to its starting position, and as the rails 27 pass backward beyond blocks 22, 23 said blocks are returned to their normal groove 24, 25 obstructing states by spring 21.
  • the upper assembly 12 is provided with a pair of magnetic inserts 51 that serve to trap ferrous metal slugs, and a pair of spring loaded pivot fingers 52 that further prevent cheating by taping coins.
  • a pair of pivotable, spring-loaded pawls 53 having teeth which engage into a series of openings 54, 54A in corresponding aligned rows on coin slide 13.
  • Pawls 53 serve to assure that once coin slide 13 has dropped coins 32, 33 onto guide surfaces 35, 36, it cannot be retracted to the ready position until it has advanced by an amount sufficient to a push the coins 32, 33 through deposit slots 38 and complete a full forward advancement.
  • Pawls 53 are selfreversing when they drop into the long slots 54A.
  • FIGS. 8, 9, 10, 11, and 14 illustrate the adjustable features of the invention which allow the user to set the coin slide assembly 10 to operate with different sizes, and hence denominations of coins.
  • the lateral guide 37 can be shifted laterally as required for different coins simply by loosening their mounting screws 61 that extend through slots 62 and 63.
  • the guides 39 have mounting screws 64 that extend through a slot 65 to allow lateral adjustment of guides 39.
  • the guide 40 is connected to lever 41 by a screw fastening 66 that extends through an arcuate slot in lever 41. This allows the amount of pivot movement imparted to lever 41 to be adjusted for various coin sizes, so that the displacement of block 22, 23 effected at end 42 of lever 41 will be sufficient to clear the groove 24, 25.
  • each lever 41 is provided with a hole 67 to permit insertion of a screwdriver (.not shown) for turning screw 43 to adjust the amount the block 22 or 23 extends into groove 24 or 25 when lever 41 is not pivoted by passage of a coin.
  • a screwdriver (.not shown) for turning screw 43 to adjust the amount the block 22 or 23 extends into groove 24 or 25 when lever 41 is not pivoted by passage of a coin.
  • the blocks 22, 23 are each shown in FIG. 7 as completely obstructing grooves 24, 25, it is to be understood that there might be some situations when, for a peculiar coin size, the amount of pivot displacement of lever 41 might be less than that needed to push each block 22, 23 completely across its groove, and the screw 43 would then be adjusted so that the block 22, 23 involved would clear its groove 24, 25 with the available lever 41 swing.
  • the duplicate blocking means comprising the combination of lever 41, guides 40, blocks 22, 23, screws 43 and spring 21 is responsive to the presence of the proper coin combination in coin slide 13 and can serve also to preventcheating by use of wrong coins.
  • the use of oversize coins is, of course, easily prevented by sizing the openings 19, to prevent their insertion.
  • insufficient lever 41 movement to effect complete withdrawal of blocks 22, 23 from grooves 24, will prevent coin slide 13 movement to its device activation position, and hence the invention prevents this type of cheating.
  • a coin slide assembly comprising in combination a lower assembly, an upper assembly releasably connected to said lower assembly and defining therewith a longitudinal guide passage, a coin slide disposed for reciprocable movement in said guide passage, and blocking means disposed to normally block the movement of said coin slide beyond a preset limit position by inserting an obstruction into said guide passage in the absence of a coin in the coin slide, said blocking means being responsive to the presence of a coin in the coin slide to remove said obstruction from the guide passage and allow movement of the coin slide beyond said limit position, said coin slide having an extending rail, said blocking means including a coin sensing lever disposed for engagement by the coin carried by the coin slide and an obstructor element disposed for movement along a path intersecting the movement path of the rail of the coin slide, said obstructor element being coupled to said lever for displacement thereby into a position withdrawn from the.
  • the improvement according to claim 1 including means disposed on said lower assembly defining a deposit slot for each coin carried by the coin slide, and guides positioned for receiving each coin carried by the coin slide and guiding such coin through said deposit slot.
  • said coin slide is disposed to receive and carry a plurality of prescribed coins and said blocking means includes a plurality of coin sensing levers each disposed for engagement by a corresponding one of such coins, and a plurality of obstructor elements, each coupled to a corresponding one of said levers for displacement thereby into a position withdrawn from the guide passage when the lever engages a respective coin.
  • said upper and lower assemblies define a longitudinal guide passage having a flat portion extending widthwise and at least one longitudinal groove portion extending transversely from said flat portion
  • said coin slide has a flat width portion disposed for insertion into said flat portion of the guide passage and a rail disposed for insertion into said groove portion of the guide passage
  • said blocking means inserts an obstructor element into the groove portion of the guide passage to engage the rail of the coin slide to block the movement thereof beyond said limit position.
  • the improvement according to claim 1 including means disposed on said lower assembly defining a deposit slot for each coin carried by the coin slide, and guides positioned for receiving each coin carried by the coin slide and guiding such coin through said deposit slot, said guides being adjustable to accommodate changes in the size of coins carried by the coin slide.
  • said coin slide is disposed to carry a plurality of specified coins
  • said blocking means is disposed to normally block the movement of the coin slide beyond said limit position by inserting into the guide passage a plurality of obstructions equal to the number of such coins, and said blocking means is responsive to the presence of each of such coins to remove the corresponding obstruction from the guide passage and allow movement of the coin slide beyond said limit position only when all of said specified coins are carried by the coin slide.
  • said coin slide is disposed to carry two specified coins in side-by-side relation
  • said blocking means includes a pair of blocks biased each for extension into a respective groove portion of the guide passage to engage respective rail parts on the coin slide to limit the movement thereof beyond said limit position.
