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
176,400 Apr. 18, 1876 Improvement in atmospheric hammers John C. Butterfield Chicago, IL This atmospheric hammer design was written up in the 1876-09-16 Engineering News, which said that "a hammer built under this patent is now on exhibition in Philadelphia". That exhibit was by H. H. Scoville. We could find no evidence that Scoville, or anyone else, ever manufactured it. This patent was subsequently improved in patent 264,859, and the fact that Butterfield improved his design does provide indirect evidence that his original hammer design was used.

230,612 Aug. 03, 1880 Power-hammer Charles M. Brown Chicago, IL
