Description: |
Although the Canadian Patent Office Record summary drawing show a brace wrench type combination tool similar to the Robinson (patent nos. 159,119 and 198,685) and Johnston (patent no. 530,419) brace wrench combination tools, the patented features here focus on the inclusion of the ratchet cylinder which is detailed in the full set of drawings -- see DATAMP entry for corresponding U.S. patent 568,381 granted September 29, 1896. See also British patent GB-189621580 registered Sept. 29, 1896 which also emphasizes the ratchet. |
