  • Pneumaticall time delayed bow release
    Publication number: 20020162546
    Abstract: A pneumatically time delayed bowstring release assembly for use with a bowstring affixed to a bow is disclosed. The bowstring release assembly is comprised of a release mechanism operated by a trigger that is time delayed by a pneumatic vacuum cylinder. The time delay of the pneumatic vacuum cylinder is controlled by the amount of airflow into the vacuum cylinder by means of an adjustable air intake valve. The cylinder is forced upwardly by an internal spring within the cylinder that is controlled by the vacuum until the air vent releases the pressure completely thus allowing the operator to reload the device.
