CLAUDE DREW, OF KINGS LYNN, ENGLAND.
To all whom it may concern Be it known that I, CLAUDE DREW, asubject of the King of England, residing at Kings Lynn, Norfolk, England, have invented new and useful Improvements in Stopper-Extractors, of which the following is a specification.
The object of the invention is to provide a new and novel form of stopper extractor which is easily insertible through the stopper and provided with means adapted to bear against the stopper on the bottom end thereof, the said means having a radial extent that will permit its having a relatively great bearing surface on the bottom of the stopper, thereby providing for withdrawing the stopper without the danger of mutilation. To this end the invention comprises a staff, a tubular member slidably mounted on the staff, an entrance screw formed at the lower end of the staff to provide means for driving the staff through a stopper, and link members connected between the staff and the sleeve, the link members being adapted for spreading and abutting the bottom face of the stopper and taking the thrust of the extracting operation. The invention is illustrated and described in but one embodiment to which, however, it is not to be restricted. The right is reserved to make such changes or alterations as the actual reduc tion to practice may suggest, in so far as such changes or alterations are compatible in spirit with the annexed claims.
The same numerals of reference designate the same parts throughout the several figures of the drawings wherein:
Figure 1 is a central vertical sectional view through the improved extractor and the neck and stopper of a bottle, the extractor being shown in its initial position after having been forced through the stopper.
Fig. 2 is a sectional view similar to Fig. 1, but shows the link members of the device spread for the extracting operation.
Fig. 3 is an enlarged plan view looking at that end of the device which penetrates the stopper the link members in this figure being shown spread for the extracting operation.
Fig. 4.- is a detail perspective view of the lower end of the staff and its attendant screw, the links which are attached between the sleeve and the staff being omitted in this figure. I
Specification of Letters Patent.
Application filed June 19, 1919.
Patented Feb. 10, 1920.
Serial No. 305,450.
Referring to the drawings, the invention is shown as comprising a staff 1 which is enlarged adjacent one end, as indicated at 2, that portion of the staff above the enlarged end being formed to provide a tang 3 designed to attach the handle 41 to the staff. The enlarged portion 2 is formed to provide a shoulder on that end opposite the tang and the stafl from this latter shoulder to its main portion tapers as indicated at 5, thus providing a frusto-conical portion connecting the enlarged portion 2 with the straight portion 1 of the staff.
At the lower extremity of the staff there is formed a screw'G which simulates a wood screw and which at the end remote from the point is of a diameter equal to or slightly greater than the sleeve 7 which is carried on the staff and which is slidable longitudinally therealong. The upper end of the sleeve is flared outwardly, as indicated at 8 to correspond in shape to the frusto-conical portion 5, the enlarged upper end of the sleeve abutting the shoulder formed at the enlarged portion 2 when the sleeve is in its normal position on the staff.
A finger gripping device 9-comprising a ring with two radially disposed diametrically opposite arms is provided and attached to the sleeve adjacent the frusto-conical portion 8 thereof. .The purpose of this finger gripping device appears hereinafter.
The sleeve is of a shorter length than the staff and-is adapted to move along the staff from the shoulder adjacent the enlarged portion 2 to the upper ends of the tapering ribs 10 which are formed with or connected to the staff adjacent its lower ends and are likewise connected with the upper end of the screw, as clearly indicated in Fig. 4-. These ribs taper in width, the pointed ends being up the staff and the full width ends connecting with the screw 6, each rib adjacent the screw being provided with an eye 11 through which there passes a pin or pivot 12, the latter serving to secure links 13 on opposite sides of the rib. The remaining ends of the links which are of course assembled in pairs, two being attached to each rib, are connected together by means of a pin 14 with a spacer 15 carried on the pin and disposed between the two links comprising any one pair. These pins 14 serve also to secure to each pair of links 13 a pair of links 16 which are disposed on the outsides of the two links 13. The remaining ends of these links 16 are pivotally attached to ears 1? formed on the lower end of the sleeve 7 .pins 18 passing through the links 16 and through the ears 17 to effect this attachment.
In the normal position of the device, the sleeve member 7 is raised on the staff until its upper end abuts the shoulder of the enlarged portion 2 adjacent the frusto-conical portion 5. In such a position of the sleeve member, the links 13 and 16 are alined in the direction of their lengths and lie against the staff 1 between the ribs 10 thereof. In such a position of the different parts of the device, the screw 6 may be made to pass through a stopper, such as the one indicated at 19 and the stafi and sleeve will follow this screw, the hole made by the screw being sufficient to permit the links as well as the sleeve passing through the stopper, as shown in Fig. 1. So soon as the device has been passed through the stopper far enough for the lower end of the sleeve to protrude through the bottom of the stopper, a pull exerted on the handle a in the direction of the length of the staff 1 will tend to raise the staff in the sleeve member and thus spread the links 16 and 18 until they assume the positions shown in Figs. 2 and 3, when the links 16 will stand substantially at right angles to the staff with the links 13 disposed diagonally with reference thereto. Continuing the pull exerted on the handle will then serve to extract the cork 19 from the neck of the bottle 20 as is clearly apparent. The cork having been extracted, to release the device it is only necessary to catch the finger grip 9 with the fingers when the hand rests on top of the handle 4: and exert a pressure tending to move the finger grip 9 toward the handle, when the sleeve and the staff are moved to assume their former positions and the links are straightened out to fall in longitudinal alinement against the staff 1, the device thereafter being extracted from the cork by reversing the operation which caused it to penetrate the cor I.
From the foregoing description and the accompanying drawings, it is believed that a clear enough understanding of the invention is to be had to render further description unnecessary.
The invention having been described, what is claimed as new and, useful is:
1. A stopper extractor comprising a staff, a sleeve in surrounding relation to the stafl and longitudinally movable therealong, the staff being formed at one end with a screw of gradually increasing diameter from this point to the point where it connects with the stafi, links pivotally connected with the staff, other links pivotally connected with the sleeve and also pivotally connect-ed with the first said links, and a handle carried by the staff at the end remote from the screw, whereby the staff and the sleeve may be moved relative to each other to effect the relative spreading of the links or their relative longitudinal alinement as are herein shown and specified.
A stopper extractor comprising a staff, a sleeve in surrounding relation to the staff and longitudinally movable therealong, the staff being formed at one end with a screw of gradually increasing diameter from this point to the point where it connects with the staff, links pivotally connected with the staff, other links pivotally connected with the sleeve and also pivotally connected with the first said links, a handle carried by the stall at the end remote from the screw, and a finger grip carried by the sleeve, whereby the staff and the sleeve may be moved relative to each other to effect the relative spreading of the links of their relative longitudinal alinement as are herein shown and specified.
3. A stopper extractor comprising a staff having a stopper penetrating element at one end, a sleeve in surrounding relation to the staff and longitudinally movable therealong, links pivotally connected with the staff adjacent the stopper penetrating element, other links pivotally connected with the sleeve and also pivotally connected with the first said links, and a handle carried by the staff at the end remote from the stopper penetrating element, whereby the staff and the sleeve may be moved relative to each other to effect the relative spring of the links or their relative longitudinal alinement as herein shown and specified.
In testimony whereof I afiix my signature.
