Nock for arrows of sport and hunting bows
First Claim
1. Nock for arrows of sport and hunting bows of the type having a nock body attachable to the end of the arrow shaft, two nock wings formed on the end of the nock body, wherein a diametrically running furrow is formed for accepting the nock-location defining section of a bowstring, ribs formed on the inside of the nock-wings, thereby narrowing the furrow at the end opposite the bottom, said ribs running perpendicular to the arrow axis, the improvement thereupon comprising:
- a first peripheral cut-off formed on the ribs at the bottom of the furrow, said first cut-off being inclined with an acute angle with respect to the perpendicular axis of the arrow in the direction towards the arrow shaft;
each nock-wing having a second peripheral cut-off formed therein, said second cut-off being inclined with an acute angle with respect to the perpendicular axis of the arrow in the direction towards the end of the nock, a first circular notch formed on the bottom of the furrow at the peripheral end of the first cut-off, and a second circular notch formed in the ribs at the inclined peripheral ends of the second cut-off, each of said circular notches being positioned perpendicular to the direction of inclination of the cut-offs for the purpose of receiving the bands defining the nock-location of the bowstring.

Abstract
A nock for arrows is disclosed. This nock is formed so that at all times during spanning of the bow and firing of the arrow, the nock-location section of the bowstring will be received in the nock so that the collar lies evenly against the bottom of the furrow of the nock for accurate firing of the arrow.

9. A nock for arrows having a shaft, to receive the nock-location section of a bowstring therein, said nock being of the type including,
a removable nock body slidably received on the shaft; -
a pair of projections being integral with and extending rearwardly from the nock, said projections defining a diametrically running furrow therebetween, wherein the nock-location defining section of the bowstring is received; a pair of ribs formed on each of said projections within the furrow on an axis being perpendicular to the longitudinal axis of the arrow, thereby forming a reduced area of the furrow and dividing said furrow into a rearward entrance portion, wherein the nock-location section of the bowstring is received in the nock, and a forward closed portion, wherein the nock-location section of the bowstring is seated during the loading and firing of the arrow; wherein the improvement comprises; each of said projections further having a recessed portion formed therein, whereby a lateral channel is formed in the forward closed portion of the furrow to receive therein the nock-location section of the bowstring when said bowstring is relaxed during the loading and firing of the arrow; each of said projections further having a first cut-off formed therein on the forward upper portion of the recessed portion, said cut-off being inclined at an acute angle in the direction of the arrow with respect to the longitudinal axis thereof; each of said ribs having a second cut-off formed therein on the lower portion thereof, said second cut-off being inclined at an acute angle in the direction of the arrow with respect to the longitudinal axis thereof; a first circular notch formed in the nock body in a location at the peripheral end of the first cut-off on a plane intersecting said first cut-off; a second circular notch formed in the ribs in a location at the peripheral end of the second cut-off on a plane intersecting said second cut-off; wherein the angle of inclination of the first and second cut-offs are substantially aligned and the first and second circular notches are so formed as to receive therein the nock-location section of the bowstring.
