Clamp For Bundling, Servicing And Supporting Cables, Wire Lines And Other Control Lines

US Patent:
2005024, Nov 3, 2005
Filed:
Apr 30, 2004
Appl. No.:
10/836789
Inventors:
Lawrence McClure - Katy TX, US
William Whitefield - Houston TX, US
International Classification:
E02D005/62
US Classification:
248230500
Abstract:
A body is molded from elastomer, preferably polyurethane, and has a hinge at one end of the body between the two arms which make up the body. A pair of metal inserts are embedded within the arms of the body, respectively, and are positioned such that three bolts can be turned to bring the two arms closer together to clamp whatever control lines are positioned between the two arms. The two arms are molded such that there is a slight separation of the two arms until the three bolts are torqued up to cause the elastomer arms to distort and firmly clamp the control lines being clamped. The two inserts, as well as the three bolts, are preferably fabricated from stainless steel but may also be fabricated from other metals, or from very hard plastic.
