Patent number: 8087160Abstract: A compression assembly tool for attaching a connector to a coaxial cable includes a tool body that supports a connector to be compressed in a compression head, a fixed handle, a moving lever handle, and an axially sliding plunger. The lever handle is pivotally connected to the tool body at the front end and to a link at the back end. The connection of the link to the back end of the lever handle and the placement of pivot points at opposite ends of the lever handle provides a scissor action appearance. The relative lengths of the lever handle, plunger and link and the placement of the pivots provides high levels of compression force and sufficient compression travel by the plunger to compress connectors of different lengths while requiring only a very limited handle opening angle, which allows maximum hand strength to be applied to the tool handles.Type: GrantFiled: November 16, 2007Date of Patent: January 3, 2012Assignee: Capewell Components Company, LLCInventors: Andrew J. Tarpill, Tadeusz Zagula

Patent number: 7814646Abstract: A compression assembly hand tool for attaching a connector to a coaxial cable tool includes a sliding carriage driven by handles through multiple stages of mechanical advantage to provide a very high level of compression assembly force in order to compress large diameter connectors. The middle and the back of a connector are engaged between relatively closely spaced, parallel, and opposed compression surfaces on the front of the tool and on the sliding carriage. Adapter inserts that slide into openings in the compression surfaces allow different connector sizes to be compressed. The tool allows the cable to extend outward from either end so that splice connectors may be attached. In the preferred design, a ratcheting system using two pawls provides the very highest level of compression force.Type: GrantFiled: October 31, 2007Date of Patent: October 19, 2010Assignee: Capewell Components Company, LLCInventors: Andrew J.

Publication number: 20090100681Abstract: An adjustable coaxial cable stripping tool for preparing an end of a coaxial cable for attachment to a connector includes first and second mechanisms located at opposite ends of the tool. The first cutting mechanism uses a pair of jaws and a planar cutting blade mounted in a replaceable blade cartridge to cut through the outer conductor and inner insulation to the inner conductor. The second cutting mechanism uses a double edged cutting blade and an adjustable stop that contacts the cut made by the first cutting mechanism to control the distance that the outer insulation is removed beyond the first cut. A third cutter is optionally provided to form a bevel on the end of the inner conductor.Type: ApplicationFiled: October 19, 2007Publication date: April 23, 2009Applicant: CAPEWELL COMPONENTS COMPANY, LLCInventor: Andrew J.

Patent number: 7059162Abstract: A flaring tool for flaring the outer conductors of two different sizes of coaxial cable includes a dome-shaped body and a reversible tool head. The tool head has first and second shafts and first and second flaring heads on opposite sides. Reversing the tool head exposes the shaft and flaring head for the corresponding size coaxial cable. The shafts match the inner diameter of the inner conductor of the coaxial cable to be flared. The flaring heads are shaped as half cones, which allow the outer conductor to be flared without deforming the insulation between the inner and outer conductors of the coaxial cable.Type: GrantFiled: August 5, 2004Date of Patent: June 13, 2006Assignee: Capewell Components, LLCInventors: Andrew J.

Patent number: 6820326Abstract: A compression assembly tool having multiple split bases for attaching connectors of different sizes to corresponding coaxial cables of different dimensions by compressing the connectors axially. The tool uses a light rigid O-frame and at least two pairs of split base supports located at different distances from a compression plunger driven by a lever handle. The handle is spring-loaded to the open position, but is held in the closed position by a wire bail for storage. The pairs of split base supports have annular bearing surfaces of different diameters that support the back of different connectors over a full 360 degrees. The split base supports are pivotally attached to the body, are held closed by a spring and are easily opened by squeezing push surfaces located on the split base supports towards each other to pivot the split base supports to the open position.Type: GrantFiled: October 5, 2002Date of Patent: November 23, 2004Assignee: Capewell Components Company, LLCInventors: Andrew J.

Patent number: 6581291Abstract: An adjustable cable slitting tool for longitudinally slitting optical fiber buffer tubes and other precision cables includes a T-shaped body and a guide that slides relative to the body to hold and guide the cable to be slit in a guide channel. A slitting blade is mounted on a blade carriage that can be precisely adjusted with an adjustment screw to control the depth the slitting blade projects into the guide channel. A scale and indicator marks allow the desired depth of cut to be adjusted with precision by comparing indicator marks on the adjustment screw with the scale and other indicator marks on the tool body. The adjustment screw has a tapered portion that drives the blade carriage through a single contact point via a ball bearing. A deformable pad material in contact with a threaded portion of the adjustment screw acts as both a friction adjustment and part of the backlash prevention mechanism.Type: GrantFiled: October 9, 2001Date of Patent: June 24, 2003Assignee: Capewell Components Company, LLCInventors: Andrew J. Tarpill, Tadeusz Zagula
