DEVICE' FOR 'EXTRACTING CORKS, 84c.

SPECIFICATION forming part of Letters Patent No. 531,670, dated January 1, 1895. Application filed November 2, 1893- Serial No. 489,826. (No model- To all whom it may concern:

Be it known that I, HARRY J. WILLIAMS, of

Meriden, in the county of New Haven and State of Connecticut, have invented certain newand useful Improvements in Devices for Extracting Corks, &c.; and I do hereby declare the followingto be a full, clear, aud ex a part of this specification, and to the letters of reference marked thereon.

. This invention has for its object to provide an improved cork-extracting implement simple in operation and construction and of great power, and which will by a continuous movement drive the screw into the cork and draw the latter out of the bottle-mouth; then by a reverse movement, discharge the cork and return the parts to first position, ready toextract another cork.

Referring to the accompanying drawings: Figure 1 is a side elevation of a device constructed in accordance with my invention. Fig. 2 is a similar view with parts in section to show the operating mechanism,the corkscrew being shown hanging in normalposition. Fig. 3 is a view similar to Fig.2 with the cork-screw in the position it occupies when entering a cork. Fig. 4 is a section on an enlarged scale showing the cork partially extracted. Fig. 5is a detail section of the block, in which the cork-screw is mounted.

Similar letters of reference in the several figures denote the same parts.

The device in the preferred embodiment, and as illustrated in the drawings, employs two operating screws, one carrying the corkscrew proper, and the other-serving togive the cork-screw and itscarrying screw a bodily retrograde movement, the operating screws preferably having right and left handthreads respectively, just as in the old well-known arrangement of screws in devices of this kind which were adapted to be held in the hand while in use.

In my present device, I employ a frame or casting A having a clamp a onone side for attaching the device rigidly to a table or other I Immediately over the annulus B, the frame is provided with a head C internally threaded, preferably for the reception of a left-hand screw D of large diameter, and having a central longitudinal opening threaded preferably only throughout the upper end for the reception of the right-hand screw E, which latter I "movement in one direction or the other, and

especially as the inner screw moves down, the elevating screw is provided with friction clutches formed by a spring Washer F at the top and a spring washer F at the bottom, which Washers are adapted to come in con tact with and bind against the top and bottom surfaces of the frame head C, thereby locking the elevating screw until positively moved by the inner screw or crank handle G attached to the upper end thereof.

The operation of the parts as thus far described, is as-follows: Assuming that the elevating screw is down and the cork-screw and its supporting screw up as in Fig. 2, if a bottle is placed in the position shown in dotted lines in said figure and the crank handle turned to the right, the efiect will be first to drive the cork-screw down into the cork, then as the 'inner or supporting screw reaches the end of its downward movement, the hub of the crank-handle will comein contact with the upper end of the elevating screw, causing the latter to turn in unison with the handle and inner screw, but being a left-hand screw, the effect of turning the crank handle to the right is to elevate both screws and draw the corkout of the mouth of the bottle as shown in Fig. 4. As the elevating screw reaches the upper end of its upward movement,'the friction clutch at its lower end locks it to the frame-head, when the crank-handle may be turned in the opposite direction to withdraw the cork-screw from the cork, the latter seating against the bottom of the elevating screw. By continuing the backward rotation of the handle, the inner screw again looks with the elevating screw, rotating the latter, and together they are lowered to the position shown in Fig. 2, ready for another operation. In operating these devices, it is found that the cork-screw is rotated even on the upward movement in drawing the cork and in order to overcome this and provide a mechanism which will rotate the cork-screw as it goes down, draw it up without rotation, then rotate it reversely to discharge the cork, I provide a head or block II into which the upper end of the cork-screw is rigidly secured, and connect this block to the lower end of the supporting screw byadouble clutch construction, that is to say, a connection which will connect the supporting and cork-screws when the corkscrew is pushed up by striking or as it is entering the cork and which will also connect the two when the cork-screw is suspended from the supporting screw, but neither of which clutch connections are operative when the cork-screw is held at an intermediate point and hence at this time the supporting screw may be rotated without turning the cork-screw. This will be betterunderstoodfrom the sectionaldrawings, wherein it will be seen that the block II fits in the central opening of the elevating screw and a stem K of the supporting screw passes down within the same, where it is provided with a cross pin k adapted to work in a central annular groove h in the block, or to fit in one or the other of the cross recesses or holes m at the top and bottom of the annular groove to lock the screw and block together.

In Fig 2, the block and cork-screw are shownhanging from the supporting screw and the pin forms a clutch with the upper recess in the block. The cork-screw in this position is supposed to have been just withdrawn from a cork.

In Fig. 3, the cork-screw is shown pushed up by being started into a cork, the pin now forming a clutch with the lower groove or recess in the block and locking the two screws together so as to rotate and force the cork screw into the cork.

When the cork-screw has been forced clear into the cork and the hub of the crank handle or the enlargement on the upper end of the supporting screw has arrested its further independent rotation and downward movement, the block will have reached the lower end of the elevating screw and as the latter begins to move up, a bearing N on its inner side comes up under the block and supports it with the pin in the intermediate position as shown in Fig. 4. Thus the elevating and supporting screws may rotate without rotating the corkscrew. At the same time the latter will be carried up with the elevating screw to withdraw the cork. Having reached the upward limit of the movement of the elevating screw and drawn out the cork, the reverse movement of the supporting screw will at once move the pin into the upper recess of the block and cause the cork-screw to partake of the reverse rotation, thus causing it to be withdrawn from the cork. A continuation of the reverse rotation of the supporting screw moves it to the upward limit of its independent movement where it looks with the elevating screw and causes the latter to be turned down to normal position ready for the extraction of another cork.

In order to insert the block II the lower end of the elevating screw is made separable, or more properly a collar M? is screwed thereon with a relatively fine right hand thread so as not to be worked 01f. This collar M serves as a convenient means for holding the spring washer at the lower end by clamping the same against the screw as shown.

The whole device, it will be seen, is extremely simple both in construction and operation, and while the details of mechanical construction shown and described are preferred, it is obvious that the clutch connection between the cork screw and its support ing screw may or may not be employed as desired, and further, it is obvious that any of the well known forms of clutch which will answer the purpose may be employed between the cork screw and its supporting screw and at one or both ends of the elevating screw to lock it against rotation until the inner or supporting screw reaches the limit of its independent movement, or for that matter, in some instances the clutches may be entirely omitted.
