  • Patent number: 4838237
    Abstract: An arrow rest is attached to an archery bow by a rigid mounting bracket having a projecting pin on which the arrow rest is carried. The arrow rest includes a mounting base and two pivot blocks which pivot independently. Each pivot block has a separate spring which biases it in a direction to normally maintain the fingers in positions where an arrow can be held in a stable seat found between oppositely curved tips of the fingers. Each finger can deflect from its normal position independently of the other finger so that differential deflection of the fingers can take place when they are subjected to differential forces applied by the arrow.
