Description: |
| Manufacturing information from the EAIA's "Directory of American Toolmakers". Besides some information on Lowentraut's markings, DAT says "One of Lowentraut's best known products is a wrench brace with a Dec. 4, 1894 patent apparently issued to an S. J. Johnston, Leesburg, VA. Lowentraut made plumber's tools, box scrapers, punches, and a range of other tools."
Some of the brace wrenches marked with this patent date also incorporate features patented by Johnston in 1898 (pat. no. 601,302). |
