  • Patent number: 5099982
    Abstract: Apparatus for piling in stacks a plurality of successive individual battery plates moving at a high rate of speed. Synchronized plates are transferred to a carrier conveyor which advances them into work stations with the leading edge of each plate raised generally vertically above its trailing edge. Sequentially in one and another of the stations, each plate is rapidly stopped so that a plurality of succeeding synchronized plates are each disengaged from the carrier and deposited in a stack on an elevator underlying each station. The elevator is retracted as each plate is deposited so that the next plate can be received on the stack. Periodically, the depositing of plates is switched from one station to another and stacks of plates are removed from the elevator associated with each station so that another stack can be formed on the elevator.
    Type: Grant
