Can Be Screwed Into the Cork by Pressing on the Handle
Improvements to the small appliances which are used every day are always welcome and appreciated. One of the latest is the unique corkscrew illustrated below,
patented by a Canadian. Up in that cold region they probably appreciate this improved device more than we would, as they frequently have cause to open a bottle. In the illustration two views are shown. The first a perspective view of the corkscrew before it is screwed into the cork and the other the position as screwed into the cork. The casing consists of a tubular metal sleeve of any diameter or length, which terminates in a corkscrew point. The sleeve is adapted to rotate around the axis of the threaded shaft, the latter terminating in an ordinary grip handle and connected with the sleeve by a coupling cap. In the center of the cap is a circular opening, through which the shaft passes. Extending down the side of the opening on opposite sides are ribs, adapted to engage in the channels of the shaft. Encircling the coupling cap is a withdrawing handle. In use the handle of the corkscrew is grasped and the sleeve part held downward, when it will rotate on the shaft. The point is placed in the cork and pressure applied to the handle, which causes the shaft to descend into the sleeve at the same time causing the sleeve to rotate, forcing the corkscrew into the cork. To draw the cork, the handle and the withdrawing handle are taken together, all the pull being necessary on the withdrawing handle. To remove the cork it is only necessary to take hold of the cork and pull upward on the handle.
The corkscrew, as described in the article, is the Peter Lymburner Robertson patent of 1905. The corkscrew was patented in both Canada and the USA (Canadian patent # 95,620 and US patent # 800,682).
We don’t yet have a Robertson in the collection, but would love to add one.
Of course, as we too live in a cold region, and often have cause to open a bottle, if you have any antique corkscrews with which you would like to part, feel free to drop us a line. We will put them to good use.
