    Abstract: The ram of a vertical milling machine is raised up from the machine base and then secured thereto in a raised position to accommodate a workpiece having a vertical dimension that is greater than the normal vertical clearance between the tool spindle on the ram and the work support table below the spindle. The method involves removing the bolts which mount the ram on the base, threading long guide screws into these bolt holes and supporting an inverted U-shaped bracket on nuts threaded on the guide screws such that the bracket is disposed in an elevated position above the ram. A lift screw is then extended downwardly through the bight portion of the bracket and is threaded into the conventional threaded eye bolt opening on the top side of the ram. Thereafter, a nut is threaded down on the lift screw against the top side of the bight section of the bracket and continued rotation of the nut causes the lift screw to be displaced upwardly to raise the ram as it is guided by the guide screws.

  • Patent number: 4124927
    Abstract: A sliding headstock automatic lathe includes a cutting tool which rotates in the same direction as the workpiece and at a speed precisely twice that of the workpiece, resulting in two or more flat cuts on the workpiece. The cutting tool is rotated by a connecting shaft driven by the same drive means which also rotates the workpiece. The connecting shaft is telescoping to accommodate the relative longitudinal movement of the lathe spindle nose and is pivotally attached between the drive means and the cutting tool to allow lateral movement of the cutting tool without slippage.

  • Patent number: 4117943
    Abstract: A device to code a machine tool holder, to preset the tool length, to mount the tool in the holder, and to inspect tool dimensions and coding. These functions are performed by a ring selector which selects different outside diameter rings in such sequence that a desired indentification of a tool by a combination of lands and grooves is accomplished, by a power torque machine which tightens the tool holder collet, by a digital height and diameter gage device which inspects the tool dimensions, and by a digital ring counter which gives a digital readout of the land and groove combination on the external surface of a tool holder.

  • Patent number: 4061059
    Abstract: A device for undercutting a rotating workpiece is provided wherein the tool carried by the toolholder is actuated into and out of engagement with the workpiece at predetermined feed locations. A base forms the mounting for the undercutter attachment with the toolholder being pivotally mounted on said base. The tool is moved axially in one direction along the workpiece to provide cutting. When the end of the travel has been reached, the tool moves in the opposite or return direction and the tool is automatically disengaged prior to reaching the start of the undercut portion. The actuator for the tool includes a pivoted arm and stationary trip cam on the machine tool. A positive latch holds the tool in the cutting position and a release trigger engages the trip cam to release the latch during the return feed at the proper position. The latch comprises a biased pin and the pivotal toolholder is biased by a spring activated cylinder.

  • Patent number: 3970903
    Abstract: A solid electrolyte tantalum capacitor comprises a porous tantalum body, a tantalum oxide film grown over the surfaces of the body, and an overlying coating of manganese dioxide wherein a conducting member is partially embedded. The conducting counterelectrode member is of a base metal such as nickel being plated with a noble metal such as gold. Alternatively, the conducting member is a base metal having an adjacent layer of graphite interposed between said base metal and said manganese dioxide. An extended portion of the conducting member serves as the cathode lead.
