20150233446 | CONNECTOR FOR SYNTHETIC AND COATED WIRE ROPE - A sleeve for terminating synthetic rope and coated wire rope has a body and a first channel, a second channel, and a third channel formed within the body. Each of the first, second, and third channels form a trilobular opening within the sleeve for receiving and crimping wire rope. The wire rope can have an eye splice formed at one end. A method of crimping the trilobular sleeve includes feeding the rope through the first channel of the trilobular sleeve, looping the rope through the second channel of the sleeve and then through the third channel of the trilobular sleeve, inserting the sleeve between upper and lower crimp dies, and pressing the sleeve between the dies, thereby crimping the sleeve to the rope. | 08-20-2015 |
20140302727 | CRIMP SLEEVE - A crimp sleeve for use with small enclosures has a body having an outer diameter and an opening having an inner diameter extending through the body. The sleeve joins a wire formed of stainless steel to a fiber formed of Vectran braid through the opening. The sleeve is formed of a material which has a high coefficient of friction relative to the wire, such as titanium. | 10-09-2014 |
20140212213 | COMPRESSION SLEEVES - A compression sleeve for connecting and swaging cable has an outer housing having one or more passages therethrough for holding a cable having a sheath thereon. The passages have a series of teeth separated by blunt roots which extrudes and removes the sheath from the cable thereby swaging the sleeve to a metal portion of the cable. The sleeve can be pressed at a first central position such that the teeth engage the sheath of the cable. The sleeve can also be pressed at subsequent positions extending outwardly from the central position of the sleeve such that the teeth engage the sheath of the cable. | 07-31-2014 |
20130305896 | CUTTER DIES - A cutter die has an upper body and a lower body having first and second cutting blades which encapsulate a rope. A first blade holder retains the upper body and a second blade holder retains the lower body. The first blade holder has an edge for supporting the wire rope and the second blade holder has an edge for supporting the wire rope. The first cutting blade and the second cutting blade can have cutting edges which are cantered and offset. | 11-21-2013 |
20130247385 | COMPOUND WIRE ROPE CUTTER - A compound wire rope cutter has a first handle and a second handle; a first lever and a second lever; and a first cutting jaw and a second cutting jaw. The first cutting jaw is formed at a distal end of the first lever. A second cutting jaw is formed at a distal end of the second lever. A first pivot pivotally connects the first handle and the second handle. A second pivot pivotally connects the first lever to the first handle. A third pivot pivotally connects the second lever to the second handle. A fourth pivot pivotally connects the first lever to the second lever. A first mechanical advantage is defined as a pivot lever length divided by a pivot jaw length, and a second mechanical advantage is defined as a handle length divided by a pivot handle length. A compound mechanical advantage is obtained by multiplying the first and second mechanical advantages together. | 09-26-2013 |
20130239417 | HAND HELD CABLE CUTTER - A hand held cable cutter has a first cutter half having a first cutting head with a first jaw having a first cutting blade formed on a first edge of the first jaw. A first pivot portion is formed in the head. A second cutter half has a second cutting head with a second jaw having a second cutting blade formed on a first edge of the second cutting blade. A second pivot portion is formed in the second head. The first and second cutting blades each has a cutting profile formed between the pivot portion and the first cutting edge and a root formed between a second cutting edge and the first pivot portion. The root and profile of the first and second cutting blades each form an overlap between the first and second cutter blades when the cutter is in a closed position. | 09-19-2013 |
