Abstract: 174,709. Koefoed, Hauberg, Marstrand, & Helweg Aktieselskabet Titan, and Barkhuus, W. Oct. 27, 1920. Grab-buckets. - In a single-rope grab having bucket halves H<1>, H<2>, the movement of a guide-pulley C away from or into contact with the grab drum T causes a rack G to move into or out of the path of the arm b of a pawl B, whereby a pivoted arm A is held or released by the pawl and the grab is prevented from or allowed to close respectively. The arm A is pivoted at M on the bucket half H<1>, and has a hooked, part L adapted to engage the pawl B pivoted on the bucket half H<2>. As shown in Fig. 4, a frame carrying the guide-pulley C is pivoted at s and the pivotal movement is transmitted through bevel sections D, E to a pinion segment F gearing with a spring-pressed rack G. When the grab is closed, hoisted, engaged with a carrier Z, and the hoisting-rope slackened, the grab assumes the position shown in Fig. 2. The hoisting-rope is then pulled taut, operating the pulley C, and thereby moving the rack G into the path of the pawl arm b and locking the buckets. The open grab is then released from the carrier Z and lowered until the rope slackens, releasing the rack G. The grab may then be closed and raised in the usual way.
