A bumper for limiting a string displacement on a projectile accelerating apparatus is described for absorbing vibrations thereof, the bumper comprising an hollowed body including an opening portion at a first end of the body, an expansion portion inside the hollowed body and adjacent to the opening portion, a damper portion adjacent to the expansion portion inside the hollowed body, the damper portion including a volume of air that is compressible when the opening portion is closed, and a string-contacting portion disposed on an exterior surface of a second end of the body, the distal wall and the string-contacting portion being moveable toward the opening portion to compress the volume of air in the damper portion in consequence of a string contact on the string-contacting portion. A projectile accelerating apparatus including same and a method of using same are also presented.

A bow string vibration and noise damper includes an aperture and a body portion. The string vibration and noise damper is configured to be mounted on the bowstring. In this way, a closed loop is created by inserting at least a portion of the body portion through the aperture. The closed loop encircles a portion of the bowstring thereby attaching the string vibration and noise damper to the bowstring.

In some embodiments, an archery bow comprises a riser, limbs and a bowstring extending between the limbs. A string stop is supported by the riser. The string stop comprises a first body member, a flexion member supported by the first body member and a bumper supported by the flexion member. At least a portion of the flexion member is oriented nonparallel to a shooting axis defined by the archery bow.

Flexible string dampers can include resilient bodies configured to be inserted between strands of a bowstring or cable in archery equipment. The dampers can include openings or recesses in along their longitudinal or transverse axes to provide additional flexibility and vibration dampening. Accessories and inserts can be added to the bowstring by positioning them within the openings or recesses, and the accessories and inserts can be exchanged from the bowstring without removing the damper and without needing external equipment such as a bow press to reduce tension on the string or cable. A damper can also be used as a peep sight with a central opening configured to change in width in response to changes in tension in the strands holding it in place.

A cocking system for retracting a string carrier on a crossbow that is substantially silent during operation.
