  • Energy saving control system for an automatic pin spotter
    Patent number: 4151993
    Abstract: A control system for an automatic pin spotter which permits the drive motor of the pin spotter to run only when needed so that energy is not wasted in the needless running of the motor and other portions of the pin spotter. The control system includes means for sensing when the pin spotter has a pin deck that is full of pins, sensing when the pin spotter is going through a pin spotting cycle and sensing whether a ball is in the pin spotter. The motor is allowed to run if the pin deck is not full, if there is a pin spotter cycle in progress, and if the bowling ball is in the pin spotter and otherwise it is turned off.
