Description: |
| This is a simple sheet metal square, with the addition of a sheet metal fence. The primary claims are for the fact that it would be very cheap to manufacture. Frederick G. Breul also went on to found the Fred G. Breul Tool Works, which is a possible manufacture. This design was widely used, but I have never seen one of these squares marked with the patent date. |
