Securing mechanism for shackle
View Patent ↗A securing mechanism for a shackle having a pair of opposed legs with an opening at one end of each of the pair of opposed legs to form a pair of opposed openings. The securing mechanism includes a shackle bolt having a head at one end and a circumferential groove near an opposed end wherein the shackle bolt is received through the pair of opposed openings in the shackle. A two piece hinged clamp assembly is received in the circumferential groove in order to retain the shackle bolt in the shackle. A retainer pin is received in an opening in the two piece clamp assembly to hold the two piece clamp assembly in a closed position. A retainer clip surrounds the retainer pin. A lock pin through the two piece clamp assembly retains the retainer pin in the two piece clamp.
1. A method to secure a shackle, which method comprises the steps of:
inserting a shackle bolt having a head at one end and a circumferential groove near an opposed end through a pair of openings in opposed legs of said shackle;
installing a two piece clamp assembly around said shackle bolt in said circumferential groove including separating a face ring and a back ring of said two piece clamp assembly by rotating about a hinge pin and moving to a closed position by closing said face ring and said back ring by said hinge pin;
inserting a retainer pin through an opening in said two piece clamp assembly in order to secure said two piece clamp assembly in said closed position; and
inserting a lock pin through an opening in said two piece clamp assembly and through a transverse recess in said retainer pin to retain said retainer pin.
2. A method as set forth in claim 1 wherein said steps are performed in reverse order to disassemble said shackle.
3. A method as set forth in claim 1 including the additional step of installing a retainer clip around said retainer pin before moving said two piece clamp assembly to said closed position.
4. A method to secure a shackle, which method comprises:
inserting a shackle bolt having a head at one end and an opposed end through a pair of openings in opposed legs of said shackle;
installing a two-piece clamp assembly around said shackle bolt at said opposed end including separating a back ring and a face ring of said two-piece clamp assembly by rotating about a hinge pin and moving to a closed position including closing said face ring and said back ring by rotating about said hinge pin;
inserting a retainer pin through an opening in said two-piece clamp assembly so that the retainer pin is parallel to the shackle bolt in order to secure said two-piece clamp assembly in said closed position.
5. A method as set forth in claim 4 including the additional step of installing a retainer clip around said retainer pin for moving said two-piece clamp assembly to said closed position.
6. A method as set forth in claim 4 wherein said two-piece clamp assembly is installed around said shackle bolt in a circumferential groove near said opposed end.
