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). In addition, look at features of the Charles E. Thompson Sept. 29, 1896 patent (no. 568,381). |
