THOMAS M. STRAIT, OF TROY, NEW YORK.

CORKSCREW.

SPECIFICATION forming part of Letters Patent No. 279,202, dated June 12, 1883.

Application filed March 24, 1883. (No model.)

To a, whom it may concern:

Be it known that 1', THOMAS M. Srau'r, a citizen of the United States, residing at Troy, in the county of Rensselaer and State of New York, have invented a new and useful Cork screw, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to corkscrews; and it has for its object to provide eflicient means for severing the cord or wire by which corks are generally secured.

To this end my invention consists in certain improvements in the construction of corkscrews, as hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 rep resents a perspective view of my corkscrew applied in position to the cork of a bottle. Fig. 2 represents a vertical section of the same. Fig. represents a detail view of the cone-shaped cutter, the latter being shown as attachable on the shank.

Like letters refer to corres 'londing parts in all the figures.

Referring to the drawings, A designates the shank of an ordinary corkscrew, provided with a suitable handle, B, and the screw 0. These parts are constructed in the usual way, and need not be described further here.

At a point on the shank between the handle and screw I fix a cutter, D. This cutter is cone-shaped, and is provided on the inside with a shoulder, d, which adapted to rest on the cork, or on the top of the bottle. Be low said shoulder the inside of the cutter is beveled off to form a sharp cutting-edge, e, the purpose of the latter being to sever the wire or cord generally employed in holding corks in bottles. The said cutting-edge may also be used to break the sealing-wax of the bottle.

The cone-shaped cutter may be fixed on the shank, as shown in Figs. 1 and 2; or the said cutter may be internally screw-threaded at the upper end, as shown in Fig. 3, and screw upon threads on the shank. By this means the cutter can be readily detached from the corkscrew and inserted upon other corkscrews, as found convenient and desirable.

The upper portion of the cutter may be provided with an extension, and a pin or other securing device can be passed through the extension and shank A, so as to secure the cutter on the shank and allow a slight yielding motion of the cutter. This manner of connection may be employed at the option of the maker.

The operation of my corkscrew can be readily understood by the foregoing descrip tion, taken in connectionwith the accompanying drawings.- The corkscrew is applied and inserted in the cork in the usual manner. By turning the handle the cutting'edge of the coneshaped cutter severs the wire or cord by whichthe cork is secured. then be extracted by pulling on the handle of the corkscrew in the usual manner. The edge of shoulder 61 also forms a cutting-edge to break the sealing-wax of the cork, and also sever the cord or wire in conjunction with the cutting-edge c.

My corkscrew will be found to work etliciently, and in practice will cut the wire or cord and extract the cork in a very short time.

l'have described the cutter as cone-shaped; but I do not limit myself to this or any other form, as the cutter can be constructed in the shape of a square, hexagon, octagon, cylinder, or triangle without departing from the spirit or scope of my invention.

\Vhat I claim is 1. A. corkscrew provided with a cutter, said cutter-having a shoulder, (Land beveled from said shoulder to form a ciittiiigedge, e, as set forth.

2. In a corkscrew, the combination, with the shank, handle, and screw, ofa cone-shaped cutter secured to the shank, substantially as and for the purpose set forth.

3. In a corkscrew, the combination, with the shank, handle, and screw, of a cone-shaped cutter adapted to be attached to the shank, said cutter having a shoulder, (I, and beveled from said shoulder to form a cutting-edge, e,

substantially as and for the purpose set forth. 4. A corkscrew provided with a cutter, said cutter having a shoulder, d, forming an inner cutting-edge, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
