First Claim
1. Archery equipment comprising in combination:
- (a) a bow having a bowstring;
(b) an arrow having a shaft, said shaft including a rear end;
(c) a segregable two part nock for disengageably engaging said rear end of said arrow with said bowstring; and
(d) said two part nock including an insert attached to said rear end of said arrow, a receiver for engaging said bowstring and for remaining engaged with said bowstring after discharge of said arrow and at least a magnet for disengageably engaging said insert with said receiver.

Abstract
A nock for use with an arrow includes a receiver having a bowstring engaging notch with a pin extending thereacross to capture and retain the bowstring within the notch and an insert permanently attached to an arrow shaft for disengageably engaging the receiver. A retention device, such as a magnet attached to the receiver, magnetically cooperating with a magnetically responsive member attached to the insert, retains the arrow shaft in engagement with the bowstring as the bowstring is pulled back. Upon release of the bowstring, the forward momentum of the arrow overcomes the retention force of the retention device and the arrow shaft disengages from the receiver to begin its flight.

18. A method for disengageably engaging an arrow with the bowstring of a bow and for discharging the arrow from the bow upon release of the drawn bowstring, said method comprising in combination:
-
(a) attaching an insert to the rear end of the shaft of the arrow;
(b) capturing the bowstring with a receiver having a notch for retaining the bowstring to maintain the receiver in engagement with the bowstring during discharge of the arrow;
(c) maintaining a magnetic force to disengageably engage the insert with the receiver to maintain the arrow attached to the bowstring as the bowstring is drawn back and upon release of the bowstring; and
(d) overcoming the magnetic force between the insert and the receiver as a function of the momentum of the arrow when the drawn bowstring comes to its position of rest to release the arrow from the bowstring. - View Dependent Claims (19, 20, 21)
