Claim:
A method for manufacturing a purse ring engageable with a bridle line of a seine for pursing the seine with a purse line during deep-sea fishing operations which comprises the steps of: fabricating an oblong-shaped, heat-treated, steel frame circumscribing a passageway, wherein the frame has a proximal end and a distal end interconnected by a first side and a second side, wherein the second side is interrupted by a gap defined by a first edge and a second edge, wherein a pivot mount is provided at the first edge, wherein an aperture is formed at the second edge, and wherein the pivot mount and the aperture are separated by a gap distance; biasing a heat-treated steel push button lock to extend from the aperture at the second edge; pivotably mounting a heat-treated steel pivot arm in the gap of the second side to selectively open and close the passageway, wherein the pivot arm has a first end and a second end, wherein the first end includes a pivot member connected to the pivot mount for movement of the pivot arm, and wherein the pivot arm defines a key guide terminating at a key guide stop; and connecting a heat-treated steel sleeve to the pivot arm, the sleeve having a distal end with an end face formed with a notch and a proximal end and forming a channel defining an axis therebetween for slidably receiving the pivot arm, wherein the sleeve defines a lateral opening to the channel, wherein the sleeve includes a key that rides in the key guide of the pivot arm, wherein the sleeve has a retracted position in which the sleeve rides over the first end of the pivot arm, and wherein the sleeve has a fully extended position in which the notch automatically depresses the push button lock and the lateral opening receives the push button lock prior to the key abutting the key guide stop, limiting the maximum distance between the pivot member at the first end of the pivot arm and the lateral opening to be substantially equal to the gap distance, and wherein the interaction of the lateral opening with the push button and the key abutting the key guide stop are maintained within a tolerance to ensure the establishment of a tight fit when the bridle line of the seine is pursed.
