Specification of Letters Patent.

Patented Oct. 3, 1905.

Application filed December 12, 1904. Serial No. 236,600.

To all 7.171107% it may concern.-

Be it known that I, PETER LYMBURNER RoB- ERTSON, of the village of Oanfield,in the county of Haldimand, in the Province of Ontario, Canada, have invented a new and useful Improvement in Corkscrews, of which the following is a specification.

The nature of my invention relates to the way in which the corkscrew can be screwed into the cork (that is to be drawn) by simply pressing downward on the handle part of the device.

Further, the objects are: that the corkscrew may be rapidly and accurately screwed into the cork, and for this purpose I provide a tubular sleeve terminating in a corkscrewpoint, and within the sleeve is arranged to screw up and down a screw-threaded shaft mounted by a suitable handle. Rotatably connecting the shaft with the sleeve is a coupling-cap, to which is fastened the withdrawing-handle. The sleeve is also adapted to receive and is provided with a removable cap that fastens over the corkscrew. part,-so as to protect it and also make it convenient for carrying. I attain these objects by the device as illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the cork screw in a condition that it might be screwed into the cork. Fig. 2 is a perspective view showing the corkscrew in the position as screwed into the cork. Fig. 3 is a vertical sectional view of the corkscrew closed up and the removable cap fastened over the end. Fig. 4 is a perspective view of the fastening-nut removed. Fig. 5 is a perspective view of the withdrawing-handle removed, and Fig. 6 is a perspective view of the coupling-cap removed.

Like letters refer to like parts throughout the specification and drawings.

In the drawings, a represents a tubular metal sleeve of any suitable diameter or length, which terminates in a corkscrewpoint 5.

The sleeve a is adapted to rotate around the axis of a screw-threaded shaft 0, which is provided with an ordinary grip-handle d. Coupling the shaft 0 in rotatable connection with the sleeve (0 is a coupling-cap e. The coupling-cap 0 consists of a radial flange f and a depending screw-threaded flange g.

The top part of the sleeve (0 is screw-threaded, by which the cap 6 may be screwed onto it. Passing through'the center part of the cap a is a circular opening IL, through which passes the shaft 0. extending down the sides of the opening it are ribs c', adapted to engage in the channels j in the shaft 0.

Adapted to and encircling the coupling-cap e is a withdrawing-handle k. The handle consists of a circular body part 1 and two arms extending outward therefrom, and through the center of the body part Z is a circular opening a, which encircles the flange g of the cap 6.

The handle it is revolubly held on the flange g by a lock-nut 0, adapted to screw on the screw-threaded part of the flange g.

On the top face of the body part Z of the handle k is a circular seat p, adapted to receive the radial flange f of the cap 6.

In Fig. 2 I have shown the device with the withdrawing-handle k omitted, as I may not always find it necessary to have the handle, as I may extend the flange f sufliciently that it may be utilized for the same purpose.

In the drawings I have shown the shaft 0 provided with two spiral channels j; but one or more may be used equally as well. Extending through the bottom end of the shaft 0' is a pin q, that is adapted to check the upward travel of the shaft 0 by coming into engagement with the ribs 6 in the opening it in the cap 6.

At the juncture of the corkscrew-point d and the sleeve (0 is a cut-away section 1', form- 'inga shoulder s, and on the cut-away section is adapted to fit up to the shoulder a removable cap t, which may be slipped onto the end of the sleeve to protectthe corkscrewpoint 6 or for a convenience for carrying.

Any of the parts may be slightly modified without deviating from the nature of my invention, as the essential feature of my invention lies in the principle of a corkscrew which may be screwed into the cork solely by a downward pressure, and to remove the cork from the corkscrew all that is necessary is to take hold of the cork and draw upward on the handle d, which causes thecorkscrew Z) to unscrew out of the cork.

The operation for drawing a cork from the bottle with my device is as follows: The handle (1 is taken hold of and the sleeve part is held downward, when it will rotate round the axis of the shaft and screw itself downward until its descent is checked by the pin q, engaging with the rib When the device isarranged in this condition, the point 5 of the corkscrew is placed on the cork and a Oppositely disposed and downward pressure is given to the handle (Z, L a screw-threaded shaft adapted to work up,

which causes the shaft cto descend downinto the sleeve, at the same time causing the sleeve to rotate around the shaft by the action of; the ribs 1' engaging in the channels j. The downward pressure on the handle and shaft also acts as a downward pressure on the whole device, which is necessary to cause the point of the corkscrew to enter into the cork."

\Vhen the shaft and handle have descended into the sleeve as far as possible, the device is ready to draw the cork.

To draw the cork, the handle (Z and the withdrawing-handle Zware taken together, and all the pull is necessary on the handle 72', as the handle Zr, sleeve a, and corkscrew-point?) are all adapted to move together.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. A corkscrew comprising a tubular sleeve, said sleeve terminating in a corkscrew-point, a screw-thread ed shaft adapted to engage within said sleeve, a handle mounted on said shaft, said sleeve adapted to rotate round the axis of said shaft, by the action of said shaft being pressed down into said sleeve, means for connecting the said shaftin rotatable combination with the said sleeve, substantially as described.

- 2. A corkscrew consisting of a tubular sleeve terminating in a corkscrew-point, a screw-threaded shaft adapted to engage within said sleeve, a handle mounted on said shaft, a coupling-cap adapted to screw on the top of said sleeve, said shaft adapted to pass through an opening in the center of said cap, ribs extending down the sides of said opening, said ribs adapted to engage in spiral channels extending around the said shaft, said sleeve adapted to rotate round the axis of said shaft by the downward movement of the said shaft in the said sleeve, substantially as described.

3. A corkscrew com arisin a tubular sleeve a I I a e said sleeve termlnating 1n a corkscrew-point,

and down in said sleeve, a coupling cap screwed on the top of said sleeve, said coupling-cap adapted to connect said sleeve in rotatable combination with said shaft, a suitable handle fastened on the end of said shaft, said sleeve adapted to rotate round the axis of said shaft by the movement up and down in said sleeve, substantially as described.

a. A corkscrew comprising a tubular sleeve,

said sleeve terminating in a corkscrew-point,

a screw-threaded shaft adapted to be operated up and down in said sleeve, a coupling-cap fixed to said sleeve and adapted to connect said shaft in combination with said sleeve,

said coupling-cap adapted to cause the said sleeve to rotate round the axis of said shaft as the shaft is operated up and down in said sleeve, an operating-handle mounted on the top of said shaft, and a withdrawing-handle revolubly attached to the said coupling-cap, substantially as described.

5. A corkscrew comprising atu bular sleeve, said sleeve terminating in a corkscrew-point, a screw-threaded shaft adapted to operate up and down in said sleeve, a coupling-cap fixed to said sleeve and adapted to connect said sleeve in rotatable combination with the said shaft, said shaft adapted to pass through a circular opening in said cap, ribs formed in said opening and adapted to engage in the channels formed in the said shaft, the said ribs engaging in said channels adapted to cause the said sleeve to rotate round the axis of said shaft when operated up or down in said sleeve, suitable handles mounted on the said sleeve and fastened to the said couplingcap, substantially as described.
