Product Locator Adjustment Device

       This invention is related to the adjustment of a large
board product into position.  Refer to Fig. A for an illustration of
the Clark Board and its locators.

      The Clark Board product is located on the Drilling Tool using 3
rectangular slots which fit over 3 square locators 1 (see Fig. B).
The locators must be positioned correctly in the direction
perpendicular to the rectangular slots to properly locate the board.

      The locator adjustment solution is illustrated in Fig. B.  This
solution gives graduated incremental adjustment to the keeper 2 in
the direction perpendicular to the slots in the board; movement in
any other direction is restricted.  The adjustment is accurate since
the initial position is not lost - even when the mounting screws 6
are loosened.  The Guide Keeper 4 is set up once and fixed to the
Table using the Mounting Screws 7.  The Differential Screw (3,4) is
used to produce graduated moves of the keeper relative to the guide
keeper.  Each notch on the differential screw (every 45 degrees)
moves the keeper approximately 0.0001".  The inside differential
screw 3 is fixed to the keeper with a set screw inside the tapped
hole 10 to ensure it does not turn with the outside differential
screw 5.  The Angle Bracket 9, fixed to the guide keeper, and the
Spring 8 preload the keeper against the differential screw to
eliminate backlash when reversing directions.
