And Pivoted Released Part Patents (Class 194/254)
  • Patent number: 7708129
    Abstract: A multiple coin actuation mechanism has a latch biased to an inward home position with its inner end extending through an upstream side of a first coin slot of a stationary front cover plate toward a rotatable carrier wheel and generally alongside an unobstructed path for insertion of a first coin through the first coin slot into a first coin recess of the carrier wheel. The latch is pivotally yieldably movable away from the carrier wheel due to engagement with a second coin in a second coin recess in the rotatable carrier wheel, as the second coin is brought into alignment with the first coin slot, to allow the second coin to pass under the latch while the latch remains in contact with the second coin, preventing its removal from the second coin recess outwardly through the first coin slot, as the carrier wheel rotates past the first coin slot.

  • Patent number: 7270225
    Abstract: A dual coin mechanism for a vending machine includes a cover plate having a peripheral flange with first and second coin slots defined therein angularly and axially offset from one another about and along an axis defined by the cover plate, and first and second coin carrier wheels mounted for rotation about the axis relative to the cover plate and respectively having first and second coin recesses angularly and axially offset from one another about and along the axis. The axially offset relationships between the first and second slots, the first and second recesses and consequently first and second paths taken by first and second coins carried in the first and second recesses ensure that the first and second coins are not brought into alignment respectively with the second and first slots and thus are made inaccessible to a user during their travel along the first and second paths.

  • Patent number: 7222711
    Abstract: A multiple coin actuation mechanism has a carrier wheel with angularly spaced first and second coin recesses aligned with first and second coin slots of a front cover plate when the carrier wheel is in an initial home position at which a user initially deposits first and second coins into the first and second coin recesses through the first and second coin slots. A pivotal coin removal blocking latch and an edge notch defined adjacent to one side of the first coin recess in the carrier wheel allows initial insertion of the first coin through the first coin slot into the first coin recess while preventing removal of the second coin from the second coin recess through the first coin slot when the carrier wheel has turned sufficiently to align the second coin recess with the first coin slot.

  • Patent number: 4830168
    Abstract: A coin and key operated cam lock comprising a cam disc mounted for rotation wherein the cam disc has a lock barrel disposed therein. A cam lever and release bar engaging ramp is provided on the cam disc which also has a coin receiving slot therein. A cam lever having a detent lug thereon is biased so that the detent lug will engage with the disc ramp to thereby releasably restrict rotation of the cam disc. A coin engaging surface is located on the underside of the lever and is engageable with a coin placed within the lock to force the detent lug out of engagement with the disc ramp to permit rotation of the cam disc to the fully locked position. The disc ramp also has stop shoulders engageable with the detent lug to prevent multiple uses of the cam lock after the coins have fallen out of the coin receiving slot.
