860,824. Hooks and shackles. GARLAND, N. June 7, 1957 [March 8, 1956], No. 7316/56. Classes 24 and 89(2). A mooring-device for ships &c. comprises a bridge 1, Fig. 1, pivoted at 2 between side-plates 54 and held in a position to close a recess 66 by a nose 8 thereon engaging a nose 9 on one end of a lever 3 pivoted at 14 between said plates. The device may be mounted on a buoy or bollard or on the main eye 53 of a shackle mooring-link SML. The other end of lever 3 carries a pin engaged in a hook 11 on a lever 4 pivoted at 13 and urged by its weighted-end 12 to engage the pin. Lever 4 is prevented from turning clockwise by a pivoted-pawl 16 secured by a wedge 18 in a socket 19 in the lever. The wedge and lever 4 are connected by lanyards 51, 20, respectively, to a lanyard 49 carrying a ball- or wedge-shaped weight 45, which is joined by a lanyard 5 to a remote controlling-position. To release a mooring wire 7 held in recess 66, lanyard 5 is pulled to take up all lost-motion, i.e. to raise weight 45, and then to remove wedge 18 from its socket 19. Thereafter, lever 4 is turned clockwise to release lever 3, and a pull on wire 7 will pivot bridge 1 to release the wire. In a modification, hook 11, Fig. 5, of lever 4 is closed by a loop 23 engaging a nose 29 and pivoted by a pin 24 in a slot 25. A lever 26 pivoted at 30 and weighted at 27 has a forked-end 31 engaging pin 24. Thus, to release pin 10, lever 26 is turned clockwise by the lanyard to move pin 24 along its slot, and move loop 23 away from nose 29. When the lever 26 engages stop 32, lever 4 is carried therewith to move hook 11 away from pin 10. In a further modification, hook 11, Fig. 7, is closed by a forked-rod 33 slidably-guided by a slot 44 and attached by a link, (not shown), to a lever 39 normally in a horizontalposition. To release pin 10, lever 39 is turned clockwise by the lanyard, and then pulled along slot 43, thus withdrawing rod 33 to the left. Further pulling on the lanyard, pivots lever 4 clockwise to remove hook 11 from pin 10. Specifications 485,173, 771,644, 772,926, 779,569, 779,970, 781,634 and 798,191 are referred to.
