Abstract

1418490 Hauling MILBRAS 14 Dec 1972 [15 Dec 1971] 57875/72 Heading B8B [Also in Division F2] A grip for a free cable winch comprises an inner jaw 17 adapted to move between the arms of a U-shaped outer jaw 18, the two jaws 17, 18 defining together a passageway for receiving a cable 9 and being capped at opposite ends by brackets 23, 24, each of which has a transverse portion 37 to which is secured a rocking piece 40 bearing on the back of the inner jaw 17, and each bracket 23, 24 being pivotable about a transverse pin 21, 22 which is also located behind the back of the inner jaw 17. The free ends of the arms of the bracket 23 extend beyond the outer jaw 18 and are connected, on the one hand, to a stop 35 on the outer jaw 18 by a spring 31 which biases the bracket 23 in the direction in which the jaws 17, 18 are clamped and, on the other hand, to the free ends of the arms of the bracket 24 through pivoted connection links 56. An arm 54 welded to the back of the bracket 24 is provided with a hole 55 for receiving the pivot pin of a connecting rod by means of which the bracket 24 is connected to a hoist-control lever (2) (Figs. 1 and 2, not shown). Each rocking piece 40 is connected to the back of the inner jaw 17 through a bi-directional connection formed by a cylindrical bead 41 on the rocking piece which is pivoted in a housing surrounding the bead over more than 180 degrees. The connection is obtained in practice by securing a small block 45 to the back of the inner jaw after mounting the bead 41 of a rocking piece 40 in a semi-cylindrical recess in the back of the jaw. The block 45 has a curved bearing surface which closes on the bead 41 and thus completes the housing for the bead. A tenon on the base of the block 45 engages with a dovetailed slot in the jaw 17, a screw passing through the block and engaging a hole tapped in the jaw. Each rocking piece 40 is provided at its top with a boss 39 which is nested into a corresponding opening in the transverse portion 37 and welded thereto. In order to grip the cable, the control lever is actuated to transmit to the pin in the hole 55 a force in the direction of arrow 58, causing the brackets 23, 24 to swing in the same direction and the beads 41 to bear upon the back of the inner jaw 17 in the direction of arrow 59.
