Adjustable CRT (Cathode Ray Tube) Mount

      Figure 1 is a cross section of a CRT (Cathode Ray Tube) mounted
to an enclosure.  The adjustment hardware is shown. It fastens the
CRT mounting ear 10 to the enclosure 12.

      A threaded stud with shoulder 14 positions the mounting ear
relative to the enclosure.  Threads are cut into the stud above and
below the shoulder.  The height of the mounting ear is set by turning
the stud within a threaded hole 16 on the enclosure.  This adjustment
allows precise spacing between the enclosure and the face of the CRT
18, which is normally an interference fit.  Such spacing enables
additional hardware to be mounted to the face of the CRT without an
interference fit, i.e., touchscreen, glare filter, transparent
overlays, etc.

      Additional hardware is necessary to lock the threaded stud in
place once the desired spacing is set.  A locking nut 20 with a
washer 22 clamps the mounting ear to the shoulder.
