Description: |
|
This is one of the most complicated and incomprehensible butt
gages ever produced. It has the usual complement of marking
arms, plus a built in arm to allow the width of the mortise to be
marked, plus a built in try/square and bevel square.
Of particular interest on this patent is the registration
mechanism used to ensure that the blade locks square when used as
a try square.
