Key to Links for Patent Information

USPTO = U.S. Patent Office . Images of the actual patent can be viewed on the U.S. Patent Office web site but a special TIFF viewer must be installed with your browser in order properly work. More information on how to configure your computer to view these patents can be found at TIFF image Viewers for Patent Images.
DATAMP = Directory of American Tool And Machinery Patents . A sister site to VintageMachinery.org with information on patents related to machinery and tools. A much easier user interface than the USPTO's for finding information on machinery patents.

Patent Number Date Title Name City Description
6,325 Apr. 17, 1849 Revolving-die spike machine Ephraim Brown Lowell, MA Of interest because co-inventor Ephraim Brown went on to invent and manufacture treadle-powered woodworking machines. Note that although the patents on either side of this one have a grant date of 1849-04-17, and this patent's drawing has the same date, the patent specification itself is dated 1849-05-18. We have no explanation for the discrepancy.
