Folding Corkscrew

From a 1917 issue of The Spatula:


An inexpensive folding corkscrew has been invented which, if desired, can be placed on a bottle at the same time that it is sealed in the bottling works, so that the purchasers may have no inconvenience in opening the container whenever he wishes.  The upper end of the screw consists of a broad eyelet which serves as a pintle to hinge to each other the two halves of which the handle is composed.  These two halves are bent at right angles and fold down against the neck of the bottle.  If desired a sealing wire can be fun through the wholes and the handle tied down.  To use the corkscrew it is only necessary to remove this wire and turn the two parts of the handle up until they form a horizontal bar which can be grasped by the hand.
