(No Model?) A. L. QV ARNSTRUM. GORKSCRBW Patented Mar. 12, 1895.

W .M. l 7 M,

To all whom it may concern.-

Be it known that ANDERS LUDVIG QVARN- s'rRoM, a subject of the King of Sweden and Norway, residing at Sundyberg, Sweden, have invented certain new and useful Improvements in Corkscrews, of which the following is a full, clear, and exact description.

This invention has relation to corkscrews, and especially that class thereof wherein a spindle is caused to screw into the cork by a downward pressure upon the handle.

One of the objects of this invention is to provide such a corkscrew in which the downward pressure upon the handle transmitted to the screw spindle will be greatest upon the latter at the beginning ofthe operation of screwing the device into the cork, so that said spindle will be caused to invariably engage in and with the'cork, after which the pressure exerted uponthe spindle ina longitudinal direction will gradually decrease during the screwing in of the same while the turning force at the same time increases.

A further object of the invention is to provide a locking device whereby the screw spindle will be prevented from rotating in the opposite direction when the cork is being pulled out of the bottle.

A still further object of the invention is to provide a corkscrew which may when telescoped together be as short as possible and thus be enabled to be carried in a very small compass.

WVith the above and other objects in view, all as will presently appear, the invention consists in the novel construction, arrangement and combination of parts as hereinafter fully described, illustrated in the drawings and pointed out in the appended claims.

In the accompanying drawings:Figure 1 is a sectional elevation of my improved corkscrew in its simple form. Fig. 2 is a detail View of a portion of the sleeve or tube B. Fig. 3 is a sectional elevation showing the corkscrew extended, the same here embodying a slight modification; Fig. 4., an elevation showing said corkscrew telescoped together. Fig. 5 is an enlarged detail view of the lower portion of the screw spindle.

To the handle A is secured a tube or sleeve A in which is arranged a tube or sleeve B CDERS LUDVIGr QVARNSTROM, OF SUN DYBERG, ASSIGNOR TO THE FIRM OF JULIUS STOOR, OF STOCKHOLM, SWEDEN.

'CORKSCREW.

SPECIFICATION forming part of Letters Patent No. 535,726, dated March 12, 18195. Application filed July 8,1893. Serial No. 479,529. (No model.)

provided with a worm groove 0 with which engages the pin E secured to the screw spindle D. The worm groove O has, as shown, an'increasing pitch upward in order that the screw spindle drawn out and placed against the cork may, when the handle is pressed down be subjected to end pressure which will be greatest atthe beginning of the operation of screwing into the cork, and which pressure will then gradually decrease while at the same time the turning force exerted upon the spindle will increase. At its top the worm groove 0 terminates in a recess Finto which the pin E can be made to engage by turning the handle slightly after the screw spindle has been completely screwed into the cork. The cork can then be pulled out in the usual manner by pulling upon the handle.

The recess F can be formed either so that the worm groove turns in the opposite direction, as shown by Fig. 1, or formed so as to run in an unchanged direction perpendicular to the axis, as in Fig. 2. The said recess can be more or less inclined as indicated by the dotted lines in said Fig. 2.

The provision and arrangements of the re cess as described, serves to prevent the screw spindle turningin an opposite direction when the cork is being pulled out, the pin E invariably engaging in the said recess to thereby form a lock for said spindle.

In order that the corkscrew when telescoped together may be short and compact, there may be a second sleeve provided which can enter the sleeve secured to the handle. This is illustrated by Figs. 3 and i of the drawings. Into the sleeve A secured to the handle A there is introduced the sleeve G which can rotate in the sleeve A in the same manner as the screw spindle in Fig. 1. In the sleeve G the spindle D itself is adapted to rotate. The sleeve G is provided with a pin E ongaging in the worm groove D of the spindle and the sleeve A is provided with a pin E engaging in the groove D of sleeve G. The worm grooves can be arranged as described above, that is with varying pitch, and the locking device between the spindle and the sleeve surrounding it also provided. The spindle may be provided with a special handle K.

In Fig. 5, the lower end of the screw spindle is represented on a larger scale. The two lines a-b and d@ being continuations of the upper and lower generatrix of the worm groove, show that the first mentioned or up per side has a greater inclination to the axis than the lower side, the angle abc being greater than the angle eclf. The inclination of the sides may vary provided the relation between the inclination of the one and that of the other he thatjust mentioned. The angle abc can for instance be almost or entirely a right angle, and the angle ecZf greater or smaller than that shown by the drawings.

By the arrangement of the screw worm shown in Fig. 5 the cork screw will be easy to screw in, as the under side of the screw makes a very acute angle to the axis of the latter. WVhen pulling out the cork the reverse will be the case, as then the upper side of the screw worm otters resistance said side making almost a right angle to the line along which the pulling force acts. Oonsequentlythepitch canbe greater than otherwise whereby the cork screw will more quickly screw in the cork.

What I claim, and desire to secure by Letters Patent, is

1. In acork screw of the class described, the combination with a screw spindle, and a sleeve surrounding the same of a worm groove and pin connection between said parts adapted to cause the rotation of the spindle when the sleeve is pressed downwardly, the pitch of said groove increasing toward the upper end of the latter, as and for the purpose specified.

2. In a corkscrew of the class described, the combination with a screw spindle, and a sleeve surrounding the same, of a worm groove and pin connection between said parts adapted to cause the rotation of the spindle when the sleeve is pressed downwardly, the pitch of the said groove increasing toward the upper end of the latter, an outermost sleeve surrounding the first mentioned sleeve, a pin and groove connection between said sleeves and a handle to which the said outermost sleeve is secured, as specified. I

3. In acorkscrew of the class described, the combination with ascre'w spindle, and a sleeve surrounding the same, of a worm groove and pin connection between said parts adapted to cause the rotation of the spindle when the sleeve is pressed downwardly, the pitch of the said groove increasing toward the upper end of the latter, and a handle to which the said sleeve is secured, and means for looking the spindle against backward rotation after the same has been screwed into a cork, consisting in an angularly arranged recess in which the upper end of the said groove terminates and-a pin carried by the spindle and adapted to engage within said recess when the spindle has been screwed into a cork, as specified.

4. In a corkscrew of the class described, the combination with a screw spindle, and a sleeve surrounding the same, of a worm groove and pin connection between said parts adapted to cause the rotation of the spindle when the sleeve is pressed downwardly, the pitch of the said groove increasing toward the upper end of the latter, an outermost'sleeve surrounding the first mentioned sleeve, a pin and groove connection between said sleeves, and a handle to which the said outermost sleeve is secured and means for locking the spindle against backward rotation after the same has been screwed intoa cork consisting in an angularly arranged recess in which the upperend of the first mentioned groove terminates and a pin carried by the spindle and adapted to engage within said recess when the spindle has been screwed into a cork, as specified.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
