UNITED STATES PATENT OEEICE.
CHARLES OHINNOOK, OF BROOKLYN, NEW YORK.
Specification forming part of Letters Patent No. 38,147, dated April 14, 1863.
To LZZ whom, it may concern.-
Beit known that I, CHARLES (lHINNocK, of Brooklyn, Kings county, and State of New York, have invented a new and Improved Device for Drawing Cor-ks from Bottles; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
Figure 1 shows the principle. The shaft of the screw drops loosely through the two cams. The lower cam or inclined plane, c, is fastened to the cage. The upper cam, b, has ratchetteeth on the top. The ratchet a above is fixed to the handle. Fig. 2 shows the same cams and ratchets enlarged. Fig. 3 shows the same as Fig. 2, extended, as is necessary to obtain a longer lift.
This arrangement is an improvement on my former invention, patented May 27, 1862. Al-
though the corkscrew then patented will draw f the corks almost without fail, objections have been made to it, it being necessary with that one that the screw pass entirely through the cork. Consequently with an old wine and old cork dust will fall into the wine.
The object of this invention is to avoid that difficulty, and combines with it drawing the cork with the same facility as the former one, as well as cheapnessin manufacturing.
When used, the action may be seen by the drawings. The shaft ofthe screw dropping loose through the cams, the screw is forced into the cork, as with an ordinary corkscrew, and will not pass through a cork of the usual length. The ratchet fastened to the handle then catches-in the ratchet on the upper end of the loose cam b. The inclined plane on b, pressing on the inclined plane c, draws the cork, as the friction on the metal cams is less than that of the screw on the cork.
What I claim, and desire to secure by Letters Patent, is-
The combination of the ratchet-cap ct, the loose snail-like cam or screw b, and the corresponding cam or screw, e, with the independent worm and pillar d, all operating together for the purpose set forth.
