Description: |
|
One of the classic patent gages. The premise here is quite
simple, but really ingenious-- use a single screw to hold 3 or
4 arms by shaping the arms such that a single pressure point can
lock them all. This worked quite well, making these popular tools
in their day.
This gage was produced for about 20 years, in both 3- and 4-arm
configurations. The shape of the arm on the 3-arm gage was
slightly different than that shown in the patent drawing (it was
hexagonal, rather than triangular).
