Universal Mono-Tabular Rule Broach – 021622110205

The idea behind the Honig rule broach is fairly straightforward. A ruled form consists of horizontal and vertical lines. Setting this using conventional rule is tedious. Casting machine makers had various solutions. The Honig represented a solution which used ordinary rule (continuously cast since the introduction of the Elrod) and hand methods. The rule was used for the lines in one direction (say, the horizontal). Each rule was broached with a little slot into which a triangular brass rod could be slipped. These gave the other direction (say, the vertical).
