From the May 17, 1879 issue of Scientific American:
Mr. L. C. Mumford, of San Francisco, Cal., has devised a cork extractor, shown in Fig. 8. It is made wholly of spring sheet metal. Its construction, as well as the manner of using, will be readily understood by reference to the engraving.
Do any of you have the 1879 version of this cork extractor?
Mumford’s patent (# 212,863) was issued on Mar. 4, 1879.
