Description: |
| This press is a toggle draw press, which is a type of punch press that achieves its maximum force at the end of the stroke. The inventor had been co-founder of press maker Zeh & Hahnemann Co., Newark, NJ, in 1905 or '06. It seems that he left the business after only a couple of years and this patent provides a data point on what he did afterward. |
