ABSTRACT:
An arrow nock which includes a base secured to the rearward end of an arrow shaft. First and second legs extending from the base are transversely spaced apart to define a bowstring notch. First and second curved beads are centrally located on the interior surfaces of the legs which define the notch and have outwardly projected crests which form a throat to impede movement of the bowstring from the seat of the notch when the arrow is not drawn back, but permit relatively free flight of the arrow when the bowstring is drawn back and released. The nock has a forwardly open cavity for assembly to the end of an arrow shaft. The cavity can have retaining ribs located therein for retention of glue to secure the nock to the arrow shaft.
