Plating Fixture Disk Retainer

      The figures illustrate a plating fixture disk retainer which
eliminates a potential of any disks ever touching or being jarred
from their specified nickel plating location.

      Fig. 1 shows the plating fixture disk retainer resting on a
nickel plating arbor 2.  Nickel plating arbor 2 is inserted through
the disks as well as a plating fixture disk retainer guide 3.
Fixtures guide 3 is in an oval shape to allow the essential space
necessary to allow the disks to be placed onto plating arbor 2 such
that the disks do not hit the upper part of the fixture when a
pendulum base 4 is resting on the load or unload station fixtures.
When plating arbor 2 is lifted and placed into the plating barrel
configuration, the disks are restrained by grooves 5 on top of the
restraining fixture.  During the plating process, the parts are not
able to escape their designated plating location and are not able to
touch any neighboring parts if they were jarred or disturbed by the
high flow rates of the nickel bath.  This becomes very critical for
parts that have physical thickness less than 50 mils.  These parts do
not have the weight distribution to stand up to high flow rates while
slowly rotating in a plating bath.  Pendulum base 4 needs to be
weighted to keep the fixture in an upright position while the barrel
configuration is rotating in the plating bath.

      Fig. 2 shows a side view of the fixture loaded at 0.50-inch
spacing.
