Description: |
|
This gage is designed to mark both the lock and hinge mortises
for a door. In operation it is very much like the Biersdorf
patent (1,142,138), but it is packaged in a much thinner
tool reminiscent of the Goodell patent (531,114) that was
in wide use at this time.
The new feature on this gage, however, is the ability to adjust
the gain for both the hinge and lock markers with a recessed
thumbwheel in the body of the tool. A very cool feature, but
probably not that useful in the real world. Once you got the
gain set the way you liked, you would never adjust it again.
