corkscrew


Early wine was stored first in terracotta amphoras and later in wooden barrels. Wine was never aged; it was briefly stored or transported and served before it had a chance to spoil. Wine glasses and decanters first appeared in Venice around the 12th century, used only for serving the wine.
Glass-blowing technology improved and in the early 18th century glass wine bottles with small bottlenecks made airtight wine storage possible. Wine could now be safely aged.
The English were the first to seal wine bottles, using cork imported from Spain or Portugal. Cork comes from the wood of the Quercus Suber or cork tree, a species of Oak native to Spain. Obviously, corkscrews were invented as an easy way of removing the cork from a bottle.
However, wine bottles were not the first bottles to be corked. Bottle tops and cans did not become common until after W.W.II. Before that time and before wine was ever corked, all kinds of substances were often stored in corked containers: beer, medicine, cosmetics and food. Many of these corked items required small corkscrews.
Who invented the first corkscrew? Corkscrew historian Ron McLean from the "The Virtual Corkscrew Museum" had this to say:
"It is unknown when and who made the first corkscrew. The first corkscrews were derived from a gun worme, a tool with a single or double spiral end fitting used to clean musket barrels or to extract an unspent charge from the barrel. By the early 17th century corkscrews for removing corks were made by blacksmiths as using a cork to stopper a bottle was well established."
Corkscrew inventors were inspired by a tool called the bulletscrew or gun worm, a device that extracted stuck bullets from rifles. McLean lists the following corkscrew patents gathered from his research as being firsts in several respective countries.
•  England: Patent No 2061 granted to Samuel Henshall, Princes Street, Parish of Christchurch, Middlesex, on August 24, 1795.
•  France: Patent No. 3571 granted to Francois Rever on February 23, 1828.
•  U. S. A.: Patent No. 27,615 (see above) granted to M.L. Byrn of New York, N.Y. for a corkscrew on March 27, 1860. However, a much earlier patent No. 15,325 (see below) was granted on July 15, 1856 to George Blanchard of New York, N.Y. for a metallic tube nutmeg grater as the handle of a corkscrew. The patent illustration shows the tubular nutmeg grater as the handle of a wire helix corkscrew with the patent description mentioning the corkscrew connection three times.
•  Germany: Patent No 16 granted to Benjamin Loew of Tilsit on July 3, 1877.
•  Canada: Patent No.16,163 granted to William Addison of Hamilton, Ontario on January 23, 1883.

Waiter's Corkscrew - Single Lever Corkscrews

German Carl Wienke invented a single lever waiter's type corkscrew called the 'Butler's Friend'. Wienke was granted a German patent (Lever Corkscrew Patent DRP 20815) on May 26, 1882. He was granted a British patent (Improvement in Lever Corkscrews No. 2,022) on April 20, 1883 and a French patent (No. 155314) on May 7, 1883.
The patent drawing on the right illustrates Wienke's American patent (No. 283,731) granted on August 21, 1883. Wienke's corkscrew design is still in common use today. The corkscrew was nicknamed the 'Waiter's Friend' or 'Butler's Friend' because it could easily remove and easily replace a cork.

Double Winged Lever Corkscrews

The double winged lever design is another common corkscrew design found in households today. The first double lever can be traced to H.S. Heeley, who was granted a British patent (No. 6,006) on April 23, 1888. Heeley's corkscrew was called the A1 Heeley Double Lever; it used pivoting links to "gain an improvement in mechanical advantage to pull a cork".
The first double winged lever patented in North America was created by the Italian designer, Dominick Rosati (see illustration below). Rosati was granted a U.S. patent (No. 1,753,026) on April 1, 1930 and a Canadian patent (No. 306,030) on November 25, 1930.

The Walker Bell

The Walker Bell corkscrew was patented in 1893 by Edwin Walker, an American designer. A simple self-pulling corkscrew that incorporated a bell shape, the Walker Bell was often used for promotional messages. The bell shape rested on the bottle top and as the corkscrew was turned the cork was pulled inside the bell. Edwin Walker's first bells were manufactured by E.S.M. Co. of Erie, Pennsylvania in the early 1890's. Walker also patented a method for making corkscrews in 1912.
The patent drawings to the left and below illustrates a Walker design for a combination corkscrew/bottle opener. (U.S. Pat No. 647775 - granted on April 17, 1900)
