  • Patent number: 4616835
    Abstract: An arrow tip for hunting arrows which includes a slotted head or blade mount fitted with a v-shaped deep slot and a v-shaped shallow slot oriented in transverse relationship in the blade mount. A first shaped base blade having a truncated tip and downwardly extending base blade legs is seated in the deep slot and a second shaped top blade, having a sharpened tip and provided with downwardly extending top blade legs, is seated in the shallow slot with the fork of the top blade legs touching the truncated tip of the base blade and the tip of the top blade projecting above the end of the blade mount. In a preferred embodiment, the extending ends of the base and top blade legs are fitted with stabilizing members projecting toward the blade mount shank and designed to bias against an arrow shaft carrying the arrow tip to impart a curvature into the top blade legs and base blade legs.

  • Patent number: 4318390
    Abstract: An arrow retainer for bows including a generally flat base plate for mounting on the frame of a bow and provided with an upward standing, tensioned support having a notch in the upper surface thereof, and a cooperating support arm for engagement with the notch when the arrow retainer is in supporting configuration. A pair of spaced retaining arms are provided in biased cooperation with the support arm to support an arrow when the arrow is nocked and the bow string drawn. When the arrow is released the arrow movement and lateral pressure depresses the support and causes the support arm and the retaining arms to retract and disengage the support and the arrow, respectively, by action of the bias against the retaining arms.
