CORK-EXTRACTOR.

Specification of Letters Patent.

Patented June 16, 1914.

Application filed October 25, 1913. Serial No. 797,267.

To all whom it may concern Be it known that I, EMMA E. KNUTsoN, a citizen of the United States, residing at International Falls, in the county of Koochiching and State of Minnesota, have invented new and useful Improvements in Cork-Extractors, of which the following is a specification.

This invention relates to cork extractors; and it has for its object the provision of a device of this character which may be constructed from a single length of wire having portions extending in opposite directions through the cork and provided with terminal anchoring ends which are adapted to be effectually drawn into the material of the cork so that the device may be permanently held therein.

Another object of the invention is the pro vision of an extractor wherein the anchoring ends thereof will tend to increase their purchase with the cork during the extracting operation.

A further object of the invention is the provision of an extractor wherein the cork anchoring or engaging portions will be located at the opposite sides of the medial center of the cork and arranged in remote points relatively so as to distribute the strain equally and thereby eliminate the possibility of tearing or destroying the cork during the extracting operation.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings :Figure 1 is a longitudinal section through a cork, showing the application of the extractor thereto and illustrating the initial positions of the anchoring extremities; and Fig. 2 is a similar view, showing the operative engagement of the anchoring extremities with the cork.

The cork 1 herein illustrated is of the usual well known construction. The extractor 2 is constructed preferably of a single piece of wire bent upon itself to provide oppositely extending legs 8, which are passed downwardly through the body of the cork and which open onto the sides of the cork at diametrically opposite points. At

points above the plane of the cork, the legs 3 are connected by a pulling crown or connecting bight portion 41:. The extremities of the legs 3, at points preferably at diametrically opposite sides of the cork are bent in opposite directions so as to form anchoring spurs or locking portions 6 which extend in the direction of the sides of the cork and which are adapted to be wholly embedded in the cork when pull in an upward direction is exerted against the crown 4: of the device.

Initially, the legs 3 are extended through the cork as previously described and the portion 6 bent up so as to enter the cork when pull is applied to the crown 4:, whereby to cause the spurs or extremities 6 to extend in opposite directions and to be located at remote points relatively, so as to minimize the possibility of destroying the corks during the extracting operation. From the construction, it is understood that on each ex tracting operation, the extremities or anchoring portions.6 tend to increase their locking engagement with the cork. The curved surfaces 7 between the extremities and the main body portions of the legs 3 form abutments to resist the withdrawing of the device from the corks beyond a certain distance.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention, as claimed.

Having thus described my invention, what I claim is 1. A cork having an extracting element constructed of a single length of wire bent in its main length to provide a pulling crown and angularly disposed legs, the legs being extended into the cork and intersecting each other at a point substantially medial of the cork, and terminally provided with looking portions to prevent the withdrawal of the legs when pull is applied to the crown.

2. A cork having an extracting element constructed of a single length of wire bent upon itself and its main length to provide a arranged in spaced relation and lying subpnlling crown and angularly disposed legs, stantially at right angles to each other. 10 the legs being extended into the cork and In testimony whereof I aflix my signature intersecting each other at a point substanin presence of two Witnesses.
