ABSTRACT:
Bells for use on log skidding cables are often angular and difficult to assemble and disassemble. A simple, streamlined bell for use on a wire cable includes a longitudinally extending passage in one end of the body of the bell for receiving the ferrule on one end of the cable. The large diameter inner end of the passage is closed by a disc which is held in the body by a split pin. A sleeve slidably mounted in the large diameter end of the passage is biased towards the other narrow diameter, closed end of the passage by a helical spring mounted in the sleeve and retained therein by an inwardly extending, annular flange on the outer end of the sleeve. A keyhole slot is provided in the body at the outer end of the passage, whereby the ferrule and the free end of a cable can be inserted into the passage. The tapering free end of a ferrule is inserted into an annular, tapering socket in the outer end of the flange and pushed to move the sleeve towards the disc so that the ferrule can be fully inserted into the passage and rotated into alignment with the passage. When the cable is released, the spring pushes the sleeve, and consequently the ferrule into a locked position in the passage. In order to remove the ferrule and release the end of the cable from the bell, it is merely necessary to reverse the process.
