Other mechanisms

In the category "other corkscrew designs" you will find the most interesting models. This is because the designs usually are so inadequate and useless that they become fascinating collectors items. For a corkscrew collector, but absolutely not for a wine entusiast needing proper equipment, these corkscrews have a special warm compartment in our hearts.


Lever corkscrews consist of one or more lever arms that are pushing the cork upwards. The lever arm turns around the turning point of the lever arm to extracts the cork. These corkscrews are usually manufactured later than 1850 and attracted lots of manufacturers. These corkscrews do not break, thus lever corkscrews are very common.


Cork splitters were sought to be an improvement from traditional straight pull corkscrews. When penetrating, the cork is splitted by the CS creating a considerable amount of cork crumbs. A cork splitter CS will surely ruin every opened bottle of wine and should be kept safely in the collection. A nice corksplitter is quite rare.


Threaded shaft corkscrews withdraw the cork by rotating a handle fixed to the shaft. The penetration appears by rotation of the handle. To extract the cork just simply change the direction of the rotation. The frame acts as a fulcrum and the handle as a lever.


Whelan obtained a patent where the extraction of the cork was supposed to manage only by the force of your fingers. This requires considerable force since it relies on no leverage. Not Lady friendly at all. Whelan himself claimed his invention made the straight pull motion easier. Having testing this CS in practice I conclude that Whelan unfortunately was very wrong in his design. May I add that most of the registred mechanisms usually were " Not user friendly". The CS was manufactured by Hipkins.


The picture above is an example of a Coney clutch cs. A locking mechanism prevents the worm from moving backwards. A wingnut can be used to extract the cork as in this wingnut CS by BB Wells. Whelan patented a direct pull mechanism. Hipkins a lever mechanism. The Hipkins actually work pretty fine and releases the cork without hesitation. The Whelan on the contrary requires lots of effort to extract the cork and is not an appropriate device at the dining table.


The traditionally lever corkscrews relies on a very simple mechanism. By leverage the force to the the cork, the cork will be extracted in no time. A simple design, and still operational. The CS is genuine quality, it will not break !

A Lever corkscrew made by Thomas Lund in London. The actual corkscrew is marked both Fleet street and Cornhill. The patent was granted to William Lund of Fleet street. Watching this corkscrew gives you some nice relief from day to day obligations. What an item and it does work !

An effective wingnut extraction mechanism. Simple and  does not require force. Wells quality !

Hipkins lever mechanism will not fail on you and in fact does not require force.

An example of a Procter cork extractor. Patented in 1863. Utterly useles !

Above a Lucian Mumford 1892 US patented corkscrew. The main advantage with this CS is that it does not destroy the physical cork. The blades are supposted to be pressed down in between the bottle neck and the cork. Todays corks are so tight that this becomes impossible and the cs is today useless.


The Whelan corkscrew requires significant force to extract the cork. Having tried it, I must say that the idea just to use your fingers to pull does not work. A completely useless devise, but what a corkscrew for the collection.

An example of a Bradnock 1883 magic twist cs. The two spikes are driven into the cork by downward pressure and a clockwise rotation. The cork is extracted by a rotary pull. Simple and operational.

Greely was granted a US patent in 1888 for a cork extractor. This is a copy of an ad for the corkscrew. The Greely extractor is much smaller than the Procter. They are both useless.

Weir received a patent 1884 for a lever arms corkscrew. The simple idea is to introduce more lever arms to create an increase in leverage force. This idea works, but by introducing more lever arms the more difficulty there is to insert the cork. Although it works, the idea is quite crazy!

Two corkscrews used in a lever mechanism. Both are made by Lund.
