Abstract
A cushioned nock is mounted on a bow string to be between the arrow and a bow string release device. The cushioned nock comprises an elastomeric cylinder having an axial hole to receive the bow string. The cylinder is slit to permit the cylinder to be spread open for mounting on the string. A split ring fits in an external groove on the cylinder and is squeezed to clamp the cylinder on the string. The cylinder has a flange at each end to prevent damage to the arrow or the release. A similar cushioned nock or a conventional plastic lined, clamp type nock is mounted on the string above the arrow to fix the nocking point on the string. It is preferred to use a cushioned nock on each side of the nocking point (the point engaged by the arrow nock). Another cushioned nock can be mounted below the release device to allow mounting the device on the string pending use.
