2336. Radford, R. H., [Ges. fuer Foerderanlagen E. Heckel]. Jan. 30. Rope grips for railways, tramways, and the like, which are actuated by the weight of the suspended load or by screw-and-nut mechanism, are arranged so that the traction and supporting ropes are approximately in the same vertical plane, while at the same time the load-suspending bolt and traction rope are brought close to one another. Fig. 2 shows a load-actuated grip having a fixed jaw f1, and a pivoted jaw f provided at its lower extremity with a roller e, which is guided in a diagonal slot in a sliding block b. The block supports the shaft a, from which the load is suspended by the hanger a', and which is provided with the usual releasing- rollers h. The weight of the load depresses the block b in the guides c, thereby moving the lower end of the pivoted jaw laterally, and causing the upper end to grip the rope. Fig. 3 shows a grip having its pivoted jaw connected at its lower end to a nut e engaging a screw of quick pitch. A projecting arm n on the end of the screw shaft comes into contact with fixed projections which partially rotate it and thereby release or tighten the grip. A guide-pulley such as o is fitted to the grip, and is preferably mounted on an extension of the fixed jaw f1 so that it may work in guides p when the carrier-rope takes a curved path.
