From an 1889 issue of The Iron Age
Empire Automatic Cork Extractor
This article, patented April 16, 1889, is manufactured by the Empire Knife Company, West Winsted, Conn. Its form and
general construction are show in the accompanying illustration. A spring in the head detaches the handle from the corkscrew rod, so that the corkscrew does not turn in the cork while pulling out, and the corkscrew can be set to turn any distance into the cork, so that the cork need not be pierced through, thus saving it for use again. The power of this corkscrew is referered to as such that the hardest corks can be pulled with ease.
Of course, the Empire Automatic Cork Extractor is the Seymour L. Alvord and Edward E. Brown patent of 1889 (number 401,672). Not often turning up with a patent mark, when they do, they are marked “PAT. APR 16 ‘89.”
This one still eludes me, if you have an Alvord and Brown patent with which you would like to part, I have plenty of tradebait available!
