ABSTRACT:
An improved bowling alley bumper system for selectively guarding against the throwing of gutter balls. Comprising the system is a gutter formed of transversely divided elongated sections of which at least one is pivotally displaceable by underside actuator apparatus from a first position cooperating with the remaining section to form a conventional unguarded gutter to a second position extending above the adjacent lane bed to afford a bumper bowling effect.
