#1I was looking up data on a thumb cuff using the very useful books that Joe Giunta published and noticed that there were two patents for the Eisaman & Rome nipper. This got me wondering which one I owned since it stated the patent date of 1888.
Basically the first patent #394162, dated Dec. 11, 1888 shows one spring between the two claws for tension and the top of the shaft handle without a cover. There are no screws shown holding the cover plate.
The second patent # 829197 issued to Rome on Aug. 21, 1906 has several improvements including a cap on the top of the shaft to protect the users hand and two springs one for each claw. The patent drawings also show two screws holding the cover plate. This improved design would require new tooling from the first model.
Removing the two screws from my nipper and popping the cover plate revealed two springs. The markings on the other plate, which is part of the body, has the patent date of 1888.
Does anyone have one marked with the 1906 date? The nippers I have seen over the years have the 1888 date. Does anyone have one without the two screws--the plate riveted in place?
I bet they just never bothered to change the patent information stamped on the cuff. So I have a 1906 patent not the 1888 patent.
