  • Self-actuating, dry-fire prevention safety device for a crossbow
    Patent number: 5085200
    Abstract: A self-actuating, dry-fire prevention device for a crossbow (10) includes a pivotable stop block (30) and a pivot pin (35) and a spring (41) to pivot said stop block into releasable locking engagement with the crossbow trigger mechanism (15) such that the trigger mechanism is blocked from operating to release the bowstring (43) in the absence of an arrow (40). The stop block (30) has an arrow contacting surface (50, 51) such that when the arrow (40) is placed into position to be fired, the arrow (40) engages the arrow contacting surface (50, 51) causing the stop block (30) to pivot out of locking engagement with the trigger mechanism (15) to allow operation of the trigger mechanism (15) and release of the bowstring (43).
