Patent number: 7178434Abstract: Apparatus for supporting a coaxial cable, or the like, and effecting cutting and stripping operations to remove a portion of one or more layers which concentrically cover a central conductor. A single blade, having a circular cutting edge, is moved in an orbital path about the cable with rotary motion of a motor translated to orbital motion of the blade through a plurality of plates relatively movable on crossed, linear, roller bearings and a shaft eccentrically affixed to the motor with the shaft and motor axes at an acute angle to one another. The shaft extends through a spherical bearing mounted in one of the plates, thereby translating nutational motion of the shaft to orbiting motion of the plate which is directly attached to the blade. A unique clamping assembly includes a pair of jaws having respective gear racks engaging a single pinion gear on a motor output shaft for linear movement of the jaws by equal distances in opposite directions.Type: GrantFiled: August 18, 2004Date of Patent: February 20, 2007Inventor: David J.

Patent number: 7013782Abstract: A cutting/stripping apparatus, and methods of operation thereof, which include at least one first blade for rotary motion about the central axis of a multi-layered workpiece, and at least two, second members/blades reciprocally movable along essentially linear axes, toward and away from the one another while remaining equally spaced on opposite sides of the central axis. The general structure of the apparatus may be a single, orbiting blade to provide cutting of the outer layer about its entire periphery and a pair of members movable toward and away from one another to engage the outer layer. The pair of members may have linear, opposed edges, or may have a V-shaped or radiused (curved) cutting edges. Electronic controls and software, together with selective operator inputs which define operation of the apparatus, permit cutting the outer layer of the workpiece by either the rotary blade or the reciprocating blades.Type: GrantFiled: February 26, 2004Date of Patent: March 21, 2006Assignee: Orbital Technologies, Inc.Inventor: David J.

Patent number: 5561899Abstract: Apparatus for feeding an insulated electrical wire, or the like, axially with respect to a transverse plane in which a single pair of blade cutting edges are supported for movement toward and away from the axis of the wire. Each blade has a continuous cutting edge forming the periphery of an opening through the blade. The wire is advanced a predetermined distance through the aligned blade openings by a pair of conveyors on opposite sides of the plane of the blade edges. The blades are moved in opposite directions to sever a premeasured length of wire from the supply by first portions of each blade edge. The severed wire portion is then moved by the conveyors to a second axial position and the blades are again moved to cause second portions of the cutting edges to pass partially through the layer of insulation, stopping before contacting the conductor. Axial movement of the wire then causes the engaged blades to sever a slug of insulation and strip it partially or fully from the conductor.Type: GrantFiled: July 10, 1995Date of Patent: October 8, 1996Assignee: Carpenter Manufacturing Co.Inventors: Thomas S. Carpenter, David D. Hand, David J. Palmowski
