Abstract: 104,042. Wardale, H., and Storey, W. R. March 7, 1916. Jib cranes.-In hydraulic cranes &c. provided with a lifting-lever, the position of the fulcrum of the lever can be varied without affecting the hook, and the ratio of the travel of the lifting-rope and the stroke of the ram can be altered, so that the power varies automatically with the load to Le raised. In the form shown in Fig. 1, the lifting- lever I, which carries a pulley 4 at one end and a weight 15 at the other, is connected by a pivot 13 to a frame 3 provided with a counterweight 7 and connected by a pivot 3a to the crane post 2. The weight 7 is connected by a rope 7a to a brake pulley 8 mounted in a fixed frame 8<a>. The hoisting chain or rope passes round the pulley 5 carried by the jib, and also round the pulley 4. When the crane is put in action on no load, the weight 7 remains stationary, and the roller 10 on the end of the ram 11, in moving upwards, acts on the lever 1 at the maximum leverage for which it is designed, the empty chains being raised rapidly. If the full load is on, the roller 10 first pushes the weight 7 backwards or upwards and the fulcrum 13 swings back until the roller 10 bears against the stop 14, whereupon lifting commences. For lighter loads, the movement of the weight 7 will be less, and the power exerted will be just sufficient to raise the load. In a modification, the brake 8 and weight 7 are replaced by a constant-pressure hydraulic ram, and in a further modification, Fig. 3, the weight 7 is mounted on the pivot connecting the levers 3<c>. In each construction, a tripping-rod 9 mounted on the post 2 is connected to a lever on the working valve so that the power is cut off when this rod is struck by the lever 1.
