“This machine is very simple and rapid in its operation…

From an 1881 issue of Scientific American


We give an engraving of a novel cork extractor lately patented by Mr. Chester C. Clark, or Brownwood, Texas, and designed for drawing corkscrew from bottles containing champagne, beer, ale, mineral waters, etc.  It is to be attached to a table, shelf, counter, and is operated by the lever handle, G, projecting from the back of the apparatus.



The bottle from which the cork is to be extracted is placed between the jaws, E, which close and hold it securely when the lever, G, is raised to drive the harpoon head, a, downward through the cork.  The lever, G, has its bearings in a cross piece of the frame, A, and carries a segmental gear wheel, F, that engages the rack on the back of the slide, B.  A shaft journaled in this slide carries at is lower end the extracting instrument, a, and is provided with a pinion near its upper end that is engaged by a bevel wheel journaled on the slide, B, and carrying an arm that extends laterally and between stops on its frame, A.

Two bill-pointed levers, b, are pivoted in a cross bar, D, and extend upward through the guides in the lower portion of the slide, B.  The bar, D, slides upon two rods projecting vertically from the bed of the machine, and is supported by spiral springs.

The operation of the machine is as follows:  The bottle being in positon between the jaws, E, the lever, G, is raised to nearly a vertical position forcing the blade, a, into the neck of the bottle, severing the wires which secure the cork and cutting the cork in two in the center.  Just as the blade passes through the cork the end of the lateral arm on the bevel wheel strikes the lower stop on the frame, A, and turns the blade, a, one-quarter around.  The lever, G, is now brought down, elevating the sliding frame and blade, and lifting the cork from the bottle.  Before the frame reaches its highest point the end of the lever on the bevel wheel, G, comes against the upper stop, causing the blade to be turned to its original position, and at this time the jaws, E, release the neck of the bottle.  The two bill-pointed levers, b, divide the cork and expel it in two parts away from the blade by the lateral motion imparted to the levers by the engagement of the curved ends by the guides on the slide, B.

This machine is very simple and rapid in its operation, and should find a large use in hotels, restaurants, and other places where large number of bottles are opened.
