Plenary Adjustment Device

      Disclosed is an invention of a mechanism to adjust a three
point Cube holding disk.

      To process the Cube through the Ultra-Stepper it has to be
oriented, it has to be secured so it will not move through the
various stages of the process, it has to be level and it has to be
exactly on the same plain as the reference disk.  This is
accomplished through the unique design of a three point adjustable
holding disk.  The disk is adjusted through the unique design of a
three point adjustment device.  The three mechanisms are located in a
base plate equally spaced and aligned with the three .060 diameter
precision ground balls located on the holding disk.  There are three
parts to each device.  The first being a fine threaded shaft, the
second being a tapered block and the third part is a compression
spring which applies back pressure between the tapered block and the
spring which eliminates thread back lash.  The ground balls rest on
the tapered blocks surface and when the shaft is turned it moves the
tapered block forward or backwards.  The taper lifts the ball
providing a three point adjustment for the Cube holding disk.  There
are also three dowel pins accurately located and press fit into the
base which provides the overall security and location for the entire
assembly (Figs. 1 and 2).
