CORK EXTRAOTOR.

CORK-EXTRACTO R.

SPECIFICATION forming part of Letters Patent No. 390,159, dated September 25, 1888.

Application filed April 3, 1886. Serial No.197,707. (No model.)

To all whom it may concern.-

Be it known that I, LEVI M. DEVORE, a resident of Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements in Cork-Extractors; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it pertains to make and use the same.

The object of my invention is to provide more reliable means for removing the cork from the corkscrew after it is drawn from the bottle, it having been found that owing to differences in the corks themselves all the extractors with which I am acquainted occasionally fail, if intended to automatically split and discharge the cork by causing it to pass a knife.

My device dispenses with a knife or cutter and bursts the cork by simple outward pressure from the interior of the cork.

In the accompanying drawings, to which reference is bad in this specification, Figure 1 is an elevation of a cork-extractor embodying one form of my invention; Fig. 2, asection on the line as y, Fig. 1; Fig. 3, a section on the line :r 3 Fig. 1.

Animportantfeature of my invention is, al lowing the cork to rotate if friction upon the corkscrew exceeds that of the bottle and of the bursting device combined, thereby avoiding screw is actuated by a crank, D E F, and has upon its upper end a sharp wire-removing hook, G. From'the bearing Oalug, whose inner face closely fits the cylinder of the corkscrew-spiral, extends downward nearly to the bottle-neck when the latter is in position to be arrested by the stop K, as shown. The con tour of this lug is shown in Figs. 1, 2, and 3. The stop K is provided with an aperture to allow the ordinary bottle-neck to project entirely through it or nearly to the point of the lug 0, while in the ordinary form the end of the neck meets the stop below the upper surface thereof.

The portion of the spiral alongside the lug 0, Fig. 1, is turned down or otherwise made of less diameter than the partimmediatelybelow the lug, in order that the point of the lug being within the elements of the outer surface of the lower portion may more readily enter the rising cork.

A most important advantage of my device is that the cork is at alltimes engaged throughout its entire length by the corkscrew, and is consequently carried upward thereby even when its lower end has passed the point of the rupturing-1ug,and thus is completely ruptured from end to end. The importance of this construction is more evident when it is considered that were the cork engaged only by that portion of the screw below the rupturing device the engaged portion must at last (in each cork extracted) become very short, and that consequently the continued rotation of the screw, instead of advancing the cork over the rupturing device, bores or grinds out its central portion and allows the fragments to fall into the open mouth of the bottle.

It is convenient, but not essential, to form the lug integrally with the bearing, for if both lug and bearing be cut on the line as y the device is still operative.

I am aware that others have combined with a corkscrew adapted to extract corks by its own rotation without longitudinal movement a fixed sleeve inclosing the corkscrew-stein, and having a cork-rupturing blade whose e11- tire working-edge slopes upward and outward from said sleeve, whereby the rotation of the cork with the corkscrew is hindered, while the cork is ruptured by radial outward force alone; and I do not claim such combination as my invention.

Having now fully set forth my invention, I do not claim as new all the parts shown, but only such novelty as is set forth in the claims which follow:

1. In a corkextractor, the combination,

with a longitudinally-fixed,rotary, spiral corkscrew supported by a fixed standard, of a cork-rupturing wedge rigidly connected with said standard lying alongside the upper part of the spiral portion of said corkscrew, and adapted to enter the rising cork and by radial force from the inside outward rupture it upon one side,whi1e the opposite side is still engaged throughout its entire length by the spiral portion of the corkscrew, whereby the automatic rupturing of the lower as well as the upper portion of the cork is rendered more certain.

2. In a cork-extractor having a longitudinally-fixed corkscrew revolubly mounted in a stationary bearing, and a stop limiting the movement of the bottle, the combination, with a corkscrew having the diameter of the upper 1
