Description: |
|
This is a very interesting special-purpose gage, designed for
marking off a fixed distance from an irregular surface. The
patent drawing shows it being used to mark off the skirting board
for stairs, but it can also be used for any general purpose
scribing.
This gage works somewhat differently than most other marking
gages. In this piece the head holds the arm perpendicular, but
the arm remains free to slide in and out. This allows the point
at the end of the arm to follow the irregular surface, while an
adjustable marking point halfway up the arm marks the same
profile on the workpiece.
The same inventor later patented an improvement to this tool
(50484 - 10/17/1865).
