ABSTRACT:
This invention relates to a modification of existing bowling alley pin setting equipment to facilitate bowling practice. The fixed pivot point of the scissor arms, supported by the scissors deck, is movable from a first position, in which the original pivot point of the scissors arms is maintained, to a second position, in which the pivot point is movable to prevent adequate closing of the scissor arms whereby an undesired pin(s) is not clamped by the scissor arms and remains on the bowling surface where it may be swept away by the sweeper during its sweeping motion. All of the necessary pin(s), required for a desired bowling practice pin combination, a clamped and raised by the scissor arms during the resetting cycle. The invention also relates to a control mechanism for controlling movement of the slidable pivot point.
