The hollow auger is 1870's, based on what I was told by another collector. There were apparently 2 patents for this, and mine is based on the first which was granted ca. 1873 if I recall.
105,896, August 2, 1870. At the time, C.S. Bonney lived in Syracuse, NY nd hadn't even founded Bonney Vise & Tool Works yet.
Part of the confusion with Bonney's history comes from the fact that he left Philadelphia after he sold the company, moved to Portsmouth, Ohio (I believe he followed his daughter and son-in-law, Archie Proctor Goldsmith, there - See pic), but continued inventing tools there which had nothing to do with Bonney Vise & Tool Works. As LS has emphasized.
The word Bonney in an Arch lists the first use date as 1876. No luck with the "jelly bean" Bonney logo yet.
And maybe USPT office wouldn’t approve the jellybean, because it merely adds an outline to the previously trademarked name?
My opinion is that the jellybean version might be considered to be covered by the TM. It is an arching BONNEY, it just happens to also be outlined.
What complicates all this is that the C.S. BONNEY marking (not arching), found on 1903 pliers, as shown on AA, is
not Bonney Vise & Tool Works or Bonney Forge & Tool Works, as LS pointed out earlier.
In 1903, C.S. Bonney had nothing to do with the company that was merely carrying on his name, but he had not stopped inventing tools. AA creates confusion by listing these patents in the Bonney section and showing these kinds of tools without clarifying the sale of Bonney Vise & Tool Works to Newkirk, Ritchie, and Bills in 1885. They chased down everything associated with C.S. Bonney and assumed it was BV&TW or BF&TW when it's neither. They missed the fact that Newkirk, Ritchie, and Bills went under, and that Armstead O. Bills became the sole proprietor of BV&TW.
As you guys know, without Bills, there would be nothing for the Princeton grads to pick up and run with!
