Definitions
- This invention relates generally to a coin chute which is operable to accept a variety of differently sized coins and coin combinations by altering or exchanging the coin carrying slide. More specifically, the coin chute includes coin sizing dogs which are arranged to be operatively associated with any one of various coin slides without requiring internal adjustment of said dogs.
- Coin controlled timing units are usually installed on commercial appliances such as clothes washers, dryers, vending machines and the like.
- the coin control is enclosed within a housing mounted on the appliance or machine and the housing is usually provided with a locked coin drawer which prevents unauthorized access to a coin receptacle located in spaced relation to the coin control.
- the coin control includes a coin chute having a coin slide reciprocally mounted in a guide track for projected and retracted movement.
- the coin slide is formed having a coin receiving portion whereby the presence of a coin therein is operative to allow projected movement of the coin slide to the operate position thereof.
- the coin is transmitted to the coin receptacle upon projected movement of the coin slide.
- the inner end of the coin slide is provided with an operator for actuating the appliance or machine upon continued projected movement of the slide to the operate position thereof.
- U.S. Pat. No. 3,763,984 overcomes the prior problem of the need to return the coin chute to the manufacturer for coin slide replacement by providing easily adjustable sizing dogs to permit accommodation of various sized coins.
- this device works, it still requires that the vending machine owner make internal adjustments to the sizing dogs of the coin chute whenever a different combination of coins other than that for which the device was originally set, is to be used.
- the present invention improves further over the prior art in the manner hereinafter described.
- the present invention provides a coin chute which allows the use of a wide combination of coins by merely altering the coin receiving portions of the slide, or replacing the slide with one having differently sized coin receiving portions to accommodate changes in coin denomination for operating the coin slide assembly.
- the coin receiving portions are formed having press fitted knock-out plugs which can be selectively removed or punched out of the slide so as to change the denomination of coins required to operate the mechanism.
- the invention provides for coin size sensing dogs which are pre-positioned to operatively engage with the coin receiving portions of the slide in use, and which do not require further adjustment when making changes in the size of the coin receiving portions of the slide.
- 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.
- a blocking means which is responsive to the missing or wrong sized coin to place an obstruction in the path of travel of the coin slide to prevent movement thereof to its operate position.
- the blocking means is responsive to the presence of the proper coin or combination of coins to remove the obstruction and thereby allow continued projected movement of the coin slide to its operate position for activating the coin-controlled device.
- the device By providing the coin slide assembly with multiple sizing dogs pre-positioned to be operable with any combination of coins received in the coin slide, the device will operate without the need to make internal adjustment to said sizing dogs.
- Additional anti-tampering means are provided, such as to prevent the use of magnetic "slugs" to operate the device, and to prevent retrieval of the coins after the mechanism is activated.

- FIG. 14 is a partial plan view of an interchangable coin slide wherein different slides are required to change coin denomination, showing, in phantom, the positioning of various coin receiving portions or openings for accepting a variety of differently sized coins and coin combinations to permit such openings to be operatively associated with the pre-positioned sizing dogs shown in phantom without requiring adjustments to the sizing dogs; and
- FIG. 15 is a plug removal tool guide to be used in combination with a punch or other similar object to remove the press fitted plugs of the coin receiving portions of a slide to change the denomination of the coins required to operate the device.
- a coin operated device 10 is composed of three (3) basic structures: an upper assembly portion 12 a coin slide 14 and a lower assembly portion 16.
- the upper and the lower portions 12, 16 form a slide chute and define therebetween a longitudinal coin slide guide track passage to receive and guide movement of the coin slide 14 between its projected and retracted positions.
- the coin slide 14 is in its retracted position wherein the coin receiving sockets 18A, 18B, 18C and 18D are outside of the guide passage awaiting receipt of the appropriate coins.
- the coins are supported in these sockets 18 (A-D) by the lower assembly 16.
- the coin sockets 18(A-D) are disposed over coin discharge openings 20A, 20B (see FIG. 5) to permit the coins carried by the slide 14 to fall therethrough into a coin recepticle or box (not shown) spaced below the coin operated device 10.
- an anti-coin holding shim structure 26 is provided. This structure is formed by a series of projections 28 extending downwardly from the bottom of the coin slide 14 and riding in a matching series of closely fitted elongated slots 29 formed in the lower assembly 16 (FIGS. 5 and 7). As can readily be seen from FIG. 7, this structure will prevent the insertion of a shim along the bottom on the coin slide 14.
- magnets 30 and associated jamming edge 32 are provided on the forward portion of the upper assembly 12. Basically, the magnets 30 are inclined upwardly toward the back portion of the upper assembly 12 to expose a wall or jamming edge 32, so that a slug, partially drawn out of its socket 18 by the magnet 30, will be forced into abutment with the jamming edge 32 and jam the slide.
- a set of magnets split into two pairs 34 A, B, and 36 A, B are provided over the coin receiving openings 20A, B to prevent the slugs from falling into the coin box.
- a second anti-shim means is also provided in the form of tapped openings 31 formed in the upper assembly as shown in FIG. 6. These openings can be provided with spacing screws (not shown) which can be inserted and screwed downwardly into close proximity to the top surface of slide 14. This provides a simple means to adjust the clearance above the slide 14 after the coin operated device 10 has been installed in an appliance.
- a center sensing dog 40 is provided. As can be seen in FIG. 4, the sensing dog 40 is carried on an arm 42 which is disposed to pivot about pin 44 and be biased downwardly by spring 45. The inter-relationship among these parts can be seen by a comparison of FIGS. 1, 3 and 4. As can be seen in FIG. 1, an identical set of compenents is provided for each line of coin holding sockets 18A, 18B, 18C, 18D in the coin slide 14.
- FIG. 10 The operation of the center sensing dog 40 can be easily understood from FIG. 10, wherein the relative location of the sensing dog 40 with respect to the coin slide 14 is shown at A.
- the sensing dog 40 Upon projected movement of coin slide 14, the sensing dog 40 passes over the middle of the coin holding socket 18.
- the coin slide illustrated in FIG. 10 has not had any of its press fitted plugs 46, 48 removed to accept the coins. However, if the plugs were removed and a washer were present in one of these sockets 18 then, upon projected movement of the coin slide 14, the sensing dog 40 would be biased downwardly into the central opening of the washer, under the influence of spring 46, and prevent further projected movement of the coin slide. If a solid coin is present in a socket 18, the sensing dog 40 will ride over the coin and thus be displaced out of its blocking position.
- a small inclined guide 50, 52 is provided at the trailing edge of each socket 18 to permit the sizing dog 40 to pass over the coin and ride up the inclined guide during continued projected movement of the slide.
- the inclined guides 50, 52 are conveniently formed by providing a partial circular groove in the slide, as can be seen from FIG. 11. This is mainly a preferred configuration from the point of view of manufacture, as any inclined guide surface would serve the same purpose.
- locking dogs 54, 54 are carried on the same arm 42 that carries the sensing dog 40.
- the locking dogs 54, 54 are also located at A, A as shown in FIG. 10; however, they are spaced away from the center-sensing dog 40, 40, a predetermined distance.
- Locking slots 56, 58 are preferably rectangular openings formed through the coin slide 14.
- a pair of sizing dogs 60, 62 are associated with each row of sockets 18A, 18B, 18C, 18D.
- these sizing dogs 60, 62 are carried by the lower assembly 16 as shown in FIGS. 4 and 8.
- the sizing dogs 60, 62 are biased upwardly by leaf springs 64, 66 as shown in FIG. 2.
- FIG. 4 shows the upward biasing interaction between leaf spring 64 and sizing dog 62.
- the leaf springs 64, 66 are secured to the lower assembly 16 by bracket 68 and a screw 70.
- the dogs 60, 62 pivot about a shaft 72 and have a spacer 74, 76 therebetween.
- the sizing dogs 60, 62 their position relative to sockets 18 in the coin slide 14 is important. It is this relationship which permits changing the denomination of the coins used in the coin slide 14 without the need for adjusting the position of the sizing dogs 60, 62.
- the sizing dogs are located at B, B and C, C. The position C, C passes over the outer press-fit knockout plugs 48 in the sockets 18 and the position B, B passes over the outer edge of the inner press fit knockout plugs 46.
- a coin receiving portion of the slide has had one or two of its associated press fit plugs removed as there will always be at least one sizing dog 60, 62 disposed near the edge of the socket 18 to sense whether the entire space is essentially filled with a coin. If the space is not essentially filled with a coin, the appropriate dog 60, 62 will be biased upwardly by leaf springs 64, 66 and abut the inner edge of the socket 18 to jam the slide 14 upon continued projected movement of the slide. If only the inner press fit plug 46 has been removed, the outer dog 60 will be prevented from jamming the slide by the presence of the outer ring 52.
- FIG. 14 shows a coin slide 114 with a number of different possible coin sockets 118 (A-H) shown in phantom so that the relationship between the various sizing dog positions B, C with respect to these different socket sizes and positions can be seen.
- the coin sockets irrespective of size, must have an edge through which one of the sizing dogs passes. This insures that regardless of the coin size, the sizing dogs will be operative without adjustment.
- either coin slides with knockout plugs (FIG. 10) or with sockets as shown in FIG. 14, may be used without requiring adjustment of the sizing dogs.
- sizing dogs 60, 62 with inclined sizing dog guides 78, 80 extending rearwardly from each socket 18 to permit easy travel of the sizing dogs 60, 62 away from the sockets 18 when a coin is present.
- the preferred embodiment of the coin chute 10 also includes anti-coin return dogs 82 (FIG. 4). With reference to FIG. 10, these are in position D,D and have as their function the prevention of movement of coin slide 14 to its retracted position in an attempt to retrieve the coin after the appliance or timing mechanism has been activated. This may be achieved, for example, by taping the coin in place.
- the anti-coin return dogs 82 are pivotally mounted and located at positions D, D, and are spring biased to project into the intermediate portion of the sockets 18.
- Each anti-coin return dog 82 rides in aligned anticoin return dog guides 84, 86, 88 provided in the coin slide 14.
- the return dogs 82 bear against the rear edge of the coin in the socket upon retracted movement of the slide to jam the slide and prevent further retracted movement thereof.
- the anti-coin return dogs prevent the return of coins which have been taped or otherwise stuck in the sockets so that they do not fall through the coin discharge openings 20A, 20B, but they also act in conjunction with the coin magnet pairs 34A, 34B, 36A, 36B to jam the coin chute 10 when magnetic slugs are used in the device.
- the magnets are positioned above the coin discharge opening 20A, 20B to prevent slugs from dropping into the coin box if the slugs should be jiggled passed the first magnets 30, 32.
- a spring 90 is disposed between a bracket 92 on the coin slide 14 and a post 94 on the upper assembly, as shown in FIG. 1.
- the bracket 92 projects upwardly from the end of the coin slide 14 and further acts as a stop member in that it abuts the upper assembly 12 when the coin slide is in its fully retracted position to prevent removal of the coin slide from the coin chute mechanism.
- a ratchet mechanism serves to prevent retracted movement of the slide until after the slide has been moved to its fully projected position to deposit the coins in the coin box.
- the ratchet mechanism includes a pawl 96 carried on the lower assembly 16 and biased by a spring 98 in the direction against an edge of coin slide 14.
- the pawl 96 coacts with notches 100 formed along the edge of the coin slide 14.
- the pawl 96 is pivoted in a counter-clockwise direction by a shoulder 102 formed on the leading end of the slide 14.
- FIG. 15 shows a plug removal tool guide 107.
- the guide has a raised collar 108 to fit into an open socket of a coin slide, thereby to mount the coin slide on the guide.
- the openings 110 can then be used as a guide or die for a punch or similar object, to aid in the removal of one or more of the press fit plugs 50, 52 from the slide by exertion of a force against the plugs 50, 52.
- the spacing between the dogs in each pair 60, 62 may be varied as required by the coins in different countries.
- a usual large coin is a quarter and a usual small coin is a dime.
- the distance between the sizing dogs would therefore be one-half the difference in diameters of these coins or about one-eighth inch.
