Description: |
| This tool combines a vernier-style inside/outside caliper with a protractor head similar to those used on combination squares.
These were produced in at least two varieties. One was identical to the patent drawing, but a (presumedly) later variant went one step further by providing with a built-in center gauge (see picture for details). The inclusion of the second arm allowed the tool to be used as a bevel gage or caliper without changing the arm orientation. Niether version is particularly well-made, but the second model eliminates the vernier on the protractor, making it even less accurate.
Known examples of both variants are marked with the manufacturer's name and patent date. |
