Connections between attorneys Wilhelm & Bonner 
and the Buffalo, New York, brace patentees.
 
Firms in which Charles Amidon took part, however tenuously, according to the Directory of American Toolmakers.

Most of the patentees listed below are presumed to be connected to the Amidon concern(s) through a common law firm (Wilhelm & Bonner) and common witnesses (Buchheit, Brady & Popps). This is based on the assumption that the attorneys would not have undertaken to prepare any patents for a competitor of Amidon or one of the related firms where a conflict of interest might arise. Note that the Emil Neuhart acting as witness and Emil Neuhart the attorney are one and the same person, establishing continuity between the firms of Wilhelm & Bonner, Neuhart & Burkhart, and Neuhart.  The attorneys Stark, Sangster, and Drake are apparently independent of Amidon.  Note also that the January 14, 1868 patent won by Amidon was in use by both the Millers Falls Company and the American Bit Brace Company. That patent date is marked on a brace of mine made by the American Bit Brace Co.  This brace calls into question the start date of the American Bit Brace Company, presently thought to be 1882 per the DAT. Patentees with italicized names seem not be be in the Amidon group in spite of their Buffalo residencies.
I am indebted to Ron Pearson for his book, The American Patented Brace, 1829-1924, and its images of patent drawings wherein I found the attorney and witness signatures that made this correlation possible. The comments in the right hand column refer to Pearson's rating system, where NS means not seen (by Pearson or anyone on whom Pearson relied), A means rarest, and B means less rare but certainly not common, C, still not common, and FF meaning frequently found. With the advent of the Internet and in particular eBay, these ratings are relatively about the same, except that some patent examples of which Pearson was unaware have now surfaced.  I have put Pearson's NS rating into italics where I know that examples do exist.  For the present, patentee's names are linked to known examples in my collection and/or in the collection of Sandy Moss, magnificently presented on his website.

I have linked the patent numbers to the excellent website of the US Patent and Trademark Office where you can look up the patent images yourself.  Entries in green contributed by Joel R.
