  • Patent number: 5819901
    Abstract: The present invention provides a weighing apparatus for weighing coins accumulated in a coin hopper using a load cell and automatically taking a periodic readings of the number of coins accumulated in the hopper. By periodically monitoring the hopper and automatically calculating the number of coins in the hopper, theft of coins and other irregularities can be easily and timely detected. The unauthorized removal of coins during an actual or purported maintenance procedure can be detected by automatically determining a count of coins before a hopper access door is opened, automatically counting the number of coins once the door is closed, and using those two counts to determine the change in the number of coins in the hopper at the time of the change.

  • Patent number: 5818917
    Abstract: An anti-vandalizing device prevents removal of the coin-return bucket through the coin-retrieval window of the lower-housing cover of a coin-operated telephone while still accommodating coin vault security involving use of one key by the coin collector and of a differently coded key for the upper housing by the maintenance person responsible for fixing the bucket in the lower housing. A guard ring mounted inside an aligned window of a guard wrap reduces the effective size of the guard wrap window to where the bucket cannot be retrieved therethrough even after being crushed against the anti-rocking screw while still accommodating user coin retrieval of his unused deposited coins. The guard ring is slidably mounted on the back side of the guard wrap so as to be retrievable from above in the space between the lower housing cover and the guard wrap when the upper housing is removed. In one embodiment a ridge about the perimeter of an installed guard ring window seats within the guard wrap window.

  • Patent number: 5615625
    Abstract: A system for the secure transportation of articles such as cheques and bank notes comprises first and second docking stations at different locations, and a secure container which mates with the docking stations. The container has a number of lockable doors into which bank notes are fed by a feeder mechanism at the first docking station. The container has its own microcontroller which monitors the status of the doors and the integrity of the container, and which can respond to external control signals while it is in transit. Once the container has been loaded at one docking station, it is transported to the second docking station at a different location, where it can be unloaded. A one-time code is generated each time the container is loaded, and must be communicated to the second docking station before the container can be unloaded. Any attempt to tamper with the container while it is in transit results in the activation of a dye dispenser, which marks the contents of the container.

  • Patent number: 5524143
    Abstract: A mechanism prevents explosion damage to coin pay telephones by providing an almost horizontal offset in the coin path so that a wad of paper cannot be moved by the weight of subsequently inserted coins. For existing phones, a retrofit provides a horizontal offset by locating a horizontal slot to one side of the existing coin chute entrance and having in back of it a relatively horizontal slippery surface for sliding the coin sideways and then downwards into a tunnel in alignment with the existing coin chute. The tunnel has a sloping bottom surface so that the coin rolls therein under the force of gravity into the existing coin chute. In another embodiment, the horizontal slot is further arranged perpendicular to the existing slot and the relatively horizontal slippery surface slides the coin back towards the horizontal slot and then downwards into the tunnel with a bottom sloping surface operative to roll the coin into the existing coin chute.

  • Patent number: 4842120
    Abstract: Jam reducing apparatus for use in coin operated machines, such as telephones, acts to prevent the insertion of coins when the entryway is obstructed by foreign matter, assists in dislodging jammed coins and discourages vandals. The apparatus comprises a coin entryway which includes an inclined surface as part of a flared end of a lid. An entry slot in an entrance blocker, which is an integral part of the lid, as in substantial alignment with the coin insert slot of the front panel of the machine in normal operation. The lid is connected to a torsion spring and is associated with a coin reject lever. The inclined surface of the entryway lies opposite the blocker slot and is angled toward an exit of the coin entryway, which directs a coin into the machine. In normal use, inserted coins pass through the entryway and are directed into a coin mechanism for coin testing. Foreign matter inserted into the machine hits the inclined surface and exerts a camming force on the lid, rotating the lid about a torsion spring.

  • Patent number: 4735344
    Abstract: The objects drop into a tray (1) from which they can be removed through a dispenser opening (2), the latter being closed by a first flap (3) that gives way when one reaches therethrough. Behind this flap (3), a second flap (17) is arranged which blocks the path (14) along which the objects pass into the tray (1) once the first flap (3) has left its rest position, and maintains this path closed until the first flap (3) has returned into its rest position. For this purpose, the first flap (3) forms the driving member, and the second flap (17) forms the driven member of a lever-cam gear with a rocker mechanism (15/16). A rocker arm (16) is guided along a cam (18) in such a way that the other rocker arm (15) repels the second flap (17) during opening of the first flap until it blocks the path (14). Until then, one rocker arm (16) closes off the interspace between the lower rim (22) of the first flap (3) and the lower rim (38) of the dispenser opening (2).

  • Patent number: 4693357
    Abstract: The specification discloses a coin mechanism for dispensing machines including two or more rectangular chutes for receiving and containing a given number of coins. A rectangular gate selectively directs coins into the chutes and a rocker arm is operable to move the gate from a first position directing coins into the first chute to a second position directing coins into the second chute when the coins reach a predetermined height in a first chute. A pawl is adjustably mounted adjacent to the second chute to prevent upward movement of a predetermined number of coins deposited in the second chute. A catch plate pivotally attached to the door of the dispensing machine below the chutes supports the coins therein. The catch plate receives a hook which prevents opening of the door until the coins in the second chute are high enough to engage the pawl. A number of intermediate chutes may be located between the first and second chutes.
