  • Patent number: 5046901
    Abstract: A flush bolt boring jig is rigidly attached to a drill. The drill has a bit which is the length of the bore to be formed in the door. The jig holds the drill rigidly so the bore being drilled in the door is parallel to the free end of the door. This is done by tracks mounted by clamps in such a way that the tracks are parallel to the free end of the door. The jig is attached to a pair of slide tubes which slide on the tracks. Since the drill is attached to the jig, as the hole in the door deepens, the drill moving with the slide tubes over the tracks moves in a straight line so that the bore being formed is exactly parallel to the free end of the door.

  • Patent number: 4848327
    Abstract: A method for placing screws in an orthopedic nail used in setting fractures of the long bones of the body. A fluoroscope assembly is used initially to develop an image on a monitor. This image enables the physician to adjust the fluoroscope assembly until the x-rays from the fluoroscope are propagated along lines which are coaxially aligned with the nail screw holes. This status of alignment is then used to allow reference marks to be made on the skin located on one or more lines projected through the limb containing the fractured bone in coaxial alignment with the nail screw holes.The limb is then incised at the location of one or more of these alignment marks allowing tubular drill guides of a jig to be set against the bone in a position of coaxial alignment with the screws holes through the nail.

  • Patent number: 4789279
    Abstract: An engine block reboring system for main bearings in which the block is mounted on a pair of rails extending laterally on a workbed and is rebored by a tool driven by a right-angle drive extension on a vertical boring machine after the position of the block has been adjusted so that the vertical axis of the boring machine spindle and the desired reboring axis are in the same vertical plane, and the proper height for the tool is set for reference, so that the bearings can be rebored by manipulating the spindle vertically and horizontally in said vertical plane with respect to the height reference. Apparatus is provided for initially properly aligning the block and keeping it in aligned position during the reboring operation.

  • Patent number: 4753556
    Abstract: Apparatus and method are disclosed for enabling a single operator to correctly position and clamp a power tool, such as a drill, onto a rail or beam-shaped workpiece. The apparatus has an adjustable clamp, comprising gauge blocks that provide snug multi-point stable contact with the workpiece in cooperation with a movable guided jaw. A sight hole ensures correct positioning of the clamp by direct viewing of a mark on the workpiece. A thrust bearing positioned between the movable clamp jaw and a clamp locking nut facilitates clamping and unclamping in repeated use and permits the application of a clamping force sufficient to carry the weight of the entire apparatus, including a power-tool attached to the clamp. The drill, including a hollow centrally-lubricated annular drill bit, is manually guided into the workpiece along guide rails attached to the clamp in the same plane as the drill axis for maximum stability during operation in any orientation.

  • Patent number: 4650379
    Abstract: A pin machining fixture 10 has a plurality of openings 25 extending through a body having exterior surfaces 11-16 that lie accurately in three pairs of parallel planes that intersect perpendicularly. Each of the through openings 25 has a location notch 26, and the apexes of location notches 26 are equally spaced apart and arranged in a plane parallel with a pair of exterior surfaces. Set screws 30 threaded into the body clamp a pin or work piece 20 in each of location notches 26 so that a portion of each pin 20 extends beyond one exterior surface for machining. An abutment key 40 is preferably adjustable within the exterior surfaces of fixture 10 for locating ends of a plurality of pins 20 to be clamped and machined.

  • Patent number: 4611957
    Abstract: A fixture for the adjustable mounting of board-like furniture parts on the work table of a drilling machine. Underneath the drilling head of the machine, backstop rails which project slightly above the supporting surface of the work table are disposed in alignment with one another and longitudinally displaceably at equal distances on opposite sides of a longitudinal central plane. The ends of a threaded spindle are threaded into the ends of the backstop rails adjacent the drilling head, the threaded spindle being provided on each half with contrary threads of equal pitch. The threaded spindle is mounted rotatably but in a longitudinally undisplaceable manner on the work table. Cursors are longitudinally displaceable on the upper sides of the backstop rails and can be fixed at given uniform distances on the associated backstop rail, and each bears a stop which is biased to a position projecting toward the surface of the work table, and which can be retracted into the cursor against the bias.

  • Patent number: 4419031
    Abstract: An apparatus for drilling matching dowel holes in at least two companion workpieces includes a frame with a top surface and a drilling mechanism driven by a motor. The drilling mechanism is slidably attached to the top surface of the frame and movable along a first drilling axis substantially parallel to the top surface. A centering mechanism automatically centers the workpieces with respect to the first axis by movement along a second axis. A positioning mechanism is rigidly attached to the centering mechanism and positions the centering mechanism such that each of the workpieces is positioned in at least two dowel hole drilling positions along the first drilling axis. The positioning mechanism includes spaced-apart first and second stop members which define first and second dowel hole drilling positions. A stop engaging member is positioned movably between the first and second stop members and rigidly connects the positioning mechanism with the centering mechanism.
