  • Device for dampening bowstring vibration
    Patent number: 5452704
    Abstract: A device adapted for attachment to a compound archery bow to dampen bowstring vibration includes paired straight arms that are urged together by spring action. The facing surfaces of the arms carry cushioning material adapted to embrace the bowstring in the undrawn state of the bow. A cam-activated trigger lever prys the arms apart as the bowstring is drawn. When the bowstring is released, the trigger allows the arms to close again upon the bowstring.
