CORKSCREW.

SPECIFICATION forming part of Letters Patent No. 784,688, dated March 14, 1905.

Application filed June 2, 1904' Serial No. 210,853.

To (I/ZZ whom, it nuoy concern:

Be it known that I. GUSTAV LORENTZ KLEI- SER, a citizen of the Kingdom of Norway, and a resident of Christiania, Norway, have invented certainnew and useful Improvements in Corkscrews, of which the following is a specification.

In many corkscrews are now used various devices intended to facilitate the uncorking of the bottle. Such means are, however, either so complicated that the corkscrews have become dearer in a disproportionate degree or they cause an injury to the bottle during the uncorking.

My invention has for its object a corkscrew which is cheap, simple in construction, and operates in a secure manner without damaging the bottle.

My invention is illustrated in the accom panying drawings. in which Figure 1 is a view of the corkscrew in folded position. Fig. 2 shows the corkscrew screwed down in a cork, and Fig. 3 illustrates how the cork has been partially drawn up by the swinging down of the handle.

My invention is preferably applicable to the usual foldable pocket-corkscrews which consist of a spring-y handle-bow 1, with interposed boss 2 for the corkscrew 3 itself. The latter is secured in its two positions in usual manner by means of knots 4.

My invention consists in the arrangement of a piece 5, the

lugs

6 and 7 of which surround the pin 8 loosely, so that the piece 5 can be turned on the pin 8 without preventing one of the branches of the bow 1 to slide on the pin when the corkscrew is opened or folded.

After having opened the corkscrew in usual manner the screw 3 is screwed completely down in the cork, as shown in Fig. 2. The handle 1 is then swung down around the pin 8 to that side on which the piece 5 is lying. During the swinging down the piece 5 first will engage the upper edge of the bottlemouth. (SeethedottedlinesinFig.2.) When, then, the handle 1 is forced farther down, the pin 8 is raised, together with the screw 3 and the cork 9, during which the piece 5 slides on the edge toward the center of the mouth, and

hereby compresses the part of the cork lying between the screw-stem 10 and the mouth, as shown in Fig. 3. In order to allow the most possible compressing, the piece 5 is on each side provided with a notch 11, Fig. 1. so that the stem 10 can project in one of said notches. hen the cork has been brought to the position shown in Fig. 3, the handle 1 is swung right up, and the last part of the uncorking will now (as the cork in the manner described above has been loosened and half-way drawn up) be undertaken with the greatest facility.

The piece 5 is curved from end to end, as shown in Fig. 1, so that when the corkscrew is in use and the pin 5 is being turned and caused by the action of the lever to successively assume the operative positions shown in Figs. 2 and 3 first its center and finally its ends will be caused to bear on the mouth of the bottle, so that the curved piece 5 will act as a cam to increase the outward movement of the corkscrew when starting the cork. Furthermore, the curved form of the piece 5 causes it to conform approximately to the shape of the mouth of the bottle and promotes the efliciency of the device when used on bottles which vary in size.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

In combination with a corkscrew, a lover, a fulcrum-piece having laterally-cxtending lugs and a pivot-pin connecting the lever to the corkscrew engaging the lugs of the fulcrum-piece and hence also pivotally connecting the fulcrum-piece to the corkscrew and lever and adapting the fulcrum-piece to lie in the angle between the corkscrew and the le- Ver, to bear on the mouth of a bottle and to be moved inwardly thereon by the action of the lever and pressed by the lever against one side of the cork to start the cork, substantially as described.

In testimony whereof I have hereunto affixed my signature, this 9th day of May, 190%, in the presence of two witnesses.
