1931 Charbonneau U. S. Patent Corkscrew

1931 Charbonneau U. S. Patent Corkscrew.  On July 14, 1931 Albert Charbonneau of Boston, Massachusetts was granted United States Patent Number 1,814,895 for his "Compound Appliance." To get his patent Charbonneau simply added a corkscrew to Maurice Roberts 1926 patent for a "Bottle Stopper." Charbonneau wanted to make Roberts invention more useful by "utilizing certain of the essential portions of the patented construction for the purpose of attaching and housing an added instrumentality, preferably a corkscrew." The tool will lift a bottle cap and reseal the bottle or pull a cork from a bottle. Like Maurice's patent, this patent was been assigned to the Roberts Specialty Manufacturing Company of Boston. It was produced using the same stamping as on the original cap lifter/sealers: "Sav-Kap, Pat. Dec. 7, 1926, Boston."

Payment preferred by check, money order, or wire transfer (all fees to sender).
