IMPROVEMENTS RELATING TO COIN DISPENSING APPARATUS

Abstract: A coin dispenser (1) pushes coins (3) out one by one from the foot of stack confined in a tube (2). The coins are then confined to a guide track (5, 11, 19, 20), each coin being pushed by the next one upstream. The track may lead upwards. At the delivery end the coins (3) topple into a chute (10) and thence into a collecting chamber (14) where they are visible through a window (15). When all the allotted coins have amassed, a mechanism (16, 17) operates to drop them into a collection pocket (18). The track may be straight, it may have an upward curve, and/or it may twist or bend to one side.

Description: "Improvements relating to Coin Dispensing Apparatus" This.invention relates to coin dispensing apparatus.and is concerned with the kind in which a mechanism at the base of a stack of coins withdraws or pushes out the coins one by one edgewise in a generally horizontal direction from the base of the stack, the latter indexing down under its own weight as the coins are removed into a delivery path. Although reference is made throughout this specificat¬ ion to coins, it will be understood that the same principles apply to tokens. Such apparatus is to be found in practically all amusement or gaming machines, particularly those known as fruit machines, which give a pay-out when a player achieves some objective. Normally, the coins are delivered to an open pocket on the front of the machine cabinet, and to travel from the dispensing mechanism to that pocket they usually slide down a chute immediately after release from the mechanism. This arrangement means that the pocket is low down, for example just below normal waist height so that the player does not have to stoop to any extent to extract his winnings. The dispensing mechanism itself has to be clear of the reels of a fruit machine and their motors, and so it is generally set quite high up towards the rear of the cabinet. This is an advantage in that servicing the dispensing mechanism and filling it with coins to prime the machine, which is normally done through a rear entry door, is quite easy. However, if the mechanism is high up, the height of the ^ stack of coins must be limited. Nowadays, nearly all amusement and gaming machines are microprocessor controlled and the entire apparatus within the cabinet has shrunk to a substantial degree as compared with the old style electro-mechanical machines. However, the cabinets have remained substantially the same size, and so there is a considerable amount of free space within them. Therefore, there are no longer the constraints on position¬ ing coin handling devices as there were at one time. It is the aim of this invention to provide a more versatile coin delivery system. According to the present invention there is provided coin dispensing apparatus comprising mechanism for withdraw¬ ing or pushing out coins one by one edgwise from the base of a stack of coins in a generally horizontal direction from the base of the stack, the latter indexing down under its own weight as the coins are removed into a delivery path, characterised in that the delivery path includes a track for guiding a continuous array of edge-to-edge coins, each coin being pushed by the adjacent upstream coin as the mechanism is operated. The track may be level, it may undulate, or it may simply lead upwards, at least over part of its length. At the delivery end of the track, the coins may be arranged to topple over and fall down a chute, one by one. Thus, the coins can be pushed up to the height of the initial stack and beyond, which means that the apparatus can be set lower down in a gaming or amusement machine than was previously customary, but still deliver coins to a pocket at the conventional height. The guide track may be of channel section with upwardly directed flanges to confine coins supported by the web of the section. Alternatively the guide track may comprise opposed channel sections open towards each other to receive edge portions of the coins. The fit will be free enough to ensure that the coins will not jam at the tightest part of the curve. With this arrangement, the radius of any upward curve can be rather less than with an open guide channel, and the coins can even be taken back towards the stack in a partly inverted state. Conveniently, the opposed channel sections are separated so that the middle portions of coins span a gap. This will make freeing any jam easier. The guide track may be twisted or bent so that the centres of the coins do not remain in the same vertical plane. For example, the stack mechanism may push the coins out in a direction parallel to the face of the machine, and as it climbs the track may turn towards that face. In another arrangement the track may snake sideways in an S- bend. This may be done by making the track as an initially straight member of a material allowing it to be twisted or bent to the required configu a ion. Downstream of the track the delivery path may include a coin accumulation chamber visible behind a window, there being means for releasing the coins in said chamber all at once to a manual collection pocket below. With this arrangement, when there is a win, the pay out drops coin by coin into the chamber so that the player can see his win amassing. Then, when the full amount is there, the bottom of the chamber is released, the coins fall through, and the player can collect. This arrangement is made particularly easy to achieve using the upward coin track, for the window must be above the collection pocket, which means that the coins must be delivered to an even higher point than usual. For a better understanding of the invention, some embodiments will now be described, by way of example, with reference to the accompanying drawings, in which: Figure 1 is a diagrammatic side elevation of coin dispensing apparatus, Figure 2 is a section, to an enlarged scale, on the line II-II of Figure 1, Figure 3 is an alternative section, to an enlarged scale, on the line II-II of Figure 1, and Figure 4 shows diagrammatic plan views of various track configurations. The apparatus has a coin dispenser 1 in which an upright tube 2 contains a stack of coins 3. At the bottom of the stack there is a mechanism 4 which when activated pushes the coins one by one from the bottom of the stack edgewise in a horizontal direction into a guide track 5. As each coin is removed, the stack indexes down under its own weight. The track 5 curves upwardly, and its form is best seen in Figure 2. It comprises two opposed rail-like members 6 arranged in mirror image fashion. Each has a ledge 7 to support a respective edge portion of the coin 3, and each has an overhanging portion 8 to form a groove 9 to trap the edge of the coin. Thus, as the dispenser 1 delivers coins they form a train which is shunted up the curved track 5, each coin pushing the next one by its edge. At the top of the track 5 the coins topple over one by one into a chute 10. To prevent unauthorized extraction of coins, there will be an anti-tip device at this point so that if the machine in which the apparatus is installed is pulled over forwards or even inverted, coins lying waiting in the track 5 will not escape. An alternative track 11 is shown in Figure 3, this being of shallow U-section with the coins resting on the web 12 and being confined between the flanges 13. This will generally be preferred where there is no slope or where it is not too steep and the curves are not too sharp. The chute 10 leads to a chamber 14 which is closed on one side by a transparent window 15 situated on the front of the machine cabinet in easy view of the player. The chamber 14 has a trap door 16 at the bottom which can be operated by a device 17 on the completion of a pay out, allowing coins accumulated in the chamber 14 to fall into a pocket 18 to which the player has manual access. Thus, when there is a win, the train of coins in the track 5 is indexed forwards and upwardly as the mechanism 4 is operated, and the appointed number of coins fall into the chamber 14 where the player can see his win accumulating. When all the coins are there, the device 17 is operated and the coins fall into the pocket 18 in a sudden cascade. Figure 4 shows that the track from the foot of the coin tube 2 need not remain in the same vertical plane. It can deviate, and in Figure 4(a) the track 19 turns the coin path through 90° in the horizontal sense as it climbs to the delivery point. In Figure 4(b) the track 20 'snakes' to one side. These configurations can easily be achieved by using a slightly flexible channel section of plastics material, manufactured straight but distortable to forms with easy • curves. The examples described all have tracks which lead upwards over at least part of their length. But a level track, or one which undulates, may also be useful for conveying coins from a dispenser to a remote collection point without appreciable loss of height. These alternatives may also twist or bend to one side or the other.
