content: This is the patent model for U.S. patent No. 166,704, a universal milling machine patented by William Krutzsch of Dayton, Ohio, on August 17, 1875. The model is mostly painted red. Of note, this model was saved from the debris of the Patent Office Fire of 1877. This machine allows materials to be milled to be separately or collectively shifted either by the machine or by hand from different standpoints. Additionally, an elastic collar slotted longitudinally can fit tightly or loosely on the spindle, allowing for different materials to be milled in different ways.
