Patent number: 4809424Abstract: A tool comprises clamping members spaced from each other on a plate that clampingly engage a coaxial cable. Drill guide members hingedly connected together are latchably secured together onto the plate and they include opposing holes centrally disposed relative to the clamped cable to enable a drill bit to pass therethrough to drill opposed openings through the jacket and shielding and into the dielectric sheathing around the center conductor, whereafter the drill bit and drill guide members are removed. A housing of the coaxial connector containing stationary and movable signal probes is mounted on the plate to position the signal probes relative to the drilled holes whereafter the signal probes are moved into electrical connection with the center conductor and ground conductor members penetrate the jacket and electrically connect with the shielding.Type: GrantFiled: May 7, 1982Date of Patent: March 7, 1989Assignee: AMP IncorporatedInventors: Edward A.

Patent number: 4790695Abstract: A modular drill jig and method of making same, characterized by parallel base, tool and bushing plates which have precision machined flat and adjacent right angle edge faces defining orthogonal reference planes and axes for aiding in fast, precision lay out of the locations of drill guide bushings and other tooling in the drill jig. The plates are removably assembled in modular fashion on common guide posts. The bushing and tool plates are movable relative to each other for clamping a part to be drilled between opposed parallel clamping faces of such plates. In the manufacture of the drill jig, the adjacent right angle edge faces on the plates enable fast and precision lay out of bores for the guide posts in the plates, such precision lay out ensuring proper vertical alignment of the plates and enabling the desired movement of the tool plate without binding thereof on the guide posts while maintaining the opposed clamping faces of the bushing and tool plates parallel.Type: GrantFiled: May 24, 1982Date of Patent: December 13, 1988Inventor: Robert R.

Patent number: 4738009Abstract: A connector and cable preparation fixture to provide a coaxial cable tap while the cable continues to pass signals. The apparatus of the present invention attaches the cable tap without shorting the conductors and without significantly changing the coaxial cable parameters which would affect the data flow therein. The fixture described herein provides a guide for a cutting operation and for the subsequent assembly of the finished connector. The connector includes a cable tap which mounts on the coaxial cable in a perpendicular manner, and a center pin which attaches to the coaxial cable center wire along the axis of the cable tap. The center pin has two prongs spaced apart in opposition to straddle the center conductor. The connector is easily installed with no measurements. The resultingconnection has a long and reliable life without causing an interruption to information or signal flow on the cable at any time.Type: GrantFiled: July 2, 1986Date of Patent: April 19, 1988Assignee: LRC Electronics, Inc.Inventors: William J. Down, Melvin Acker

Patent number: 4730959Abstract: An edge joining fixture is provided comprising a spacer which is secured to the ends of a pair of boards by a clamp with the ends of the board abutting the spacer so that the ends will be properly aligned. A body member having drill bit bushings formed therein is positioned between the board members and rests upon the upper edges of the board members and is then clamped into position. A drill bit is then moved downwardly through the bushings to create dowel holes in the edges of the boards. A clamp on the body member is then released and the body member moved to the next dowel hole location where the body member is again clamped into position. The procedure is repeated until all of the desired dowel holes have been formed.Type: GrantFiled: September 28, 1987Date of Patent: March 15, 1988Inventors: Frank D. Aerni, Deborah J. Aerni

Patent number: 4669929Abstract: A drilling apparatus especially useful in drilling holes in wooden joists and studs, through which plumbing and electrical cables are to be routed, includes a bracket for engaging a joist or stud and a movable carriage supporting an electric motor and drill bit. A lever mechanism moves the carriage, and hence the motor and drill bit forcibly toward the bracket, forcing the drill bit through the joist. Countertorque from the drill bit is resisted by the coaction of the bracket and the drill bit in the hole being drilled. This avoids possible loss of balance by the operator.Type: GrantFiled: January 10, 1986Date of Patent: June 2, 1987Inventor: Karl R. Olesen

Patent number: 4639171Abstract: The dowel hole drilling machine comprises a workpiece support. One part of the workpiece support and a crosspiece carrying the drilling unit are mounted to be pivotally movable in unison about an axis. That workpiece support comprises eccentrically mounted supports, which are adapted to be aligned and flush with the workpiece support and to protrude beyond a workpiece support, which extends at right angles to the workpiece support and is spaced the same distance from the pivotal axis as the workpiece support. The workpiece support serves to support the workpiece during a horizontal drilling operation. When the drilling unit is in a vertical position, the stops are flush with the workpiece support and serve as stops for the drilling of the first row of dowel holes. This results in an exact coordination of the drill and the workpiece support, which constitutes a stop for and defines the location of the reference edge during the horizontal and vertical drilling operations.Type: GrantFiled: February 28, 1985Date of Patent: January 27, 1987Assignee: Schleicher Maschinenbau und -Vertrieb GmbHInventor: Johann Maier
