Amazing sliding frames

A sliding frame barrel is an improvement as compared to a straight pull corkscrew. The frame of a straight pull CS cannot assist in centering the worm at the beginning of the cork penetration. The sliding frame does just that and can slide vertically on the shaft.

 

The most famous of the sliding frame corkscrew is the John Loach corkscrew. Loach was granted a patent for the mechanism in 1844. His corkscrew is fantastic when polished to a vibrant color restoring its original patina and impression. Also, the Jones II patent is hybrid of a sliding frame. The worm is penetrated using 2 spikes  and the cork is ejected by a straight pull approach. The Jones II is an often sought CS and comes with either a badge or the markings stamped into the barrowl. Still after 150 years the crown of English patented corkscrews.

 

Loach also added two spikes to his invention, thus preventing the cork to turn by the studs. The cork could then easily be withdrawn by pressing down the handle. Simplicity made to work consistently and smoothly. One of the patents that ever worked.

 

Chinnock made a simple sliding frame design. Although simple to it's design it will work and not fail on you. Chinnock made a brass variant as displayed below. Fantastic piece !

A nice example of a Loach. Polished to it's original patina and shining as a crown juwel. Excellent piece !
 

A US patented version of the Chinnock.

The Chinnock mark. Patented may 1862. There is a US steel version as well as a UK brass version known. Simple but functional pieces.

A Chinnock with excellent patina. A simple design but a magnificent touch. The Chinnock will require force to extract the cork.

 

An unmarket gold plated sliding frame. Probably made in Germany. A common piece !

An example of a Jones II.

The hybrid of a sliding frame but still not. Patented in 1842. A nice example is rare.
 

 

C. V. Heljestrand manufactured a sliding frame corkscrew very similiar to Chinnock. Hyper rare !
