Improvements in Machine Cork Drawers.
I, JOHN BECK, of 121, Queens Road, in the City of Liverpool, Draper, do hereby
declare the nature of the said invention to be as follows:-
This invention relates to that class of cork drawers which are operated by a
pivotted handle arranged to revolve through a segment of a circle.
A cork drawer according to this invention comprises; a corkscrew, forming one
end of a spindle whose other end is grooved with a screw of opposite direction to
that of the corkscrew; a straight groove in said spindle; a fixed sleeve surround-
ing the spindle and forming a guide therefor and provided with slots, and a nut
or matrice for the corkscrew; a movable sleeve surrounding the fixed sleeve, and
provided with slots divided by a bridge piece, and a bell mouth; a collar on the
spindle, having trunnions which pass through the slots in the sleeves and enter
slots in the operating handle, and which may have antifriction rollers; balls,
held in recesses at each side of the collar, which enter the upper screw groove of
the spindle; a tubular casing; a bracket; and a pivotted operating handle.
The operation of the cork drawer is as follows:-The handle in its normal
position may stand vertically, and may be arranged to work through one eighth of
a circle. As the handle begins its descent the balls in the collar engage with the
threaded portion of the spindle and cause the corkscrew to revolve in the nut in
the fixed sleeve and to emerge therefrom and pass into a cork which is held against
it. The balls in the collar at this point enter the longitudinal groove in the
spindle, so that the latter no longer turns. The collar trunnions now come in
contact with the bridge piece of the movable sleeve which is consequently pushed
forward, and, as its bell mouth rests on the bottle shoulder, the bottle is forced
away from the cork. In the upward stroke of the handle the collar balls pass up
the longitudinal groove in the spindle and then enter the screw groove therein
and turn the spindle in the reverse direction, thus stripping the cork, against the
fixed nut before referred to.
The spindle above mentioned is preferably solid, with a screw groove and longi-
'tudinal groove formed in it, or it may be tubular with such groove cut in it; and
the thread of the screw groove may be either single or double pitched.

statement:—
This invention relates to that class of cork drawers which are operated by a
pivotted handle arranged to revolve through a portion of a circle.
In the annexed drawing, Figure 1 is a side view, Figure 2 a front view, Figure 3
a section, Figure 4 a detail, and Figure 5 a modified detail, of a cork drawer
according to this invention.
a is the cork screw, which is attached to the lower extremity of a hollow spindle
or tube b (Figure 4) in the upper part of which is cut a double spiral slot or thread
of opposite direction to that of the corkscrew, namely, the double screw threads
of the hollow spindle 6 have a left hand twist and the corkscrew possesses a right
hand twist. Each of the screw threads C of the spindle b resolves
itself into a straight slot''d, on opposite sides of the spindle. e is a
fixed tube surrounding the hollow spindle b and forming a guide there-
for. The tube e carries a. nut or matrix in its lower end.
pins g secure the nut f and the tube e to the outer case h. i is a movable
sleeve which slides between the tube e and the case h and is provided with a bell
mouth is a pin passing through the screw threads of the spindle 6 and
through slots in the tubes e h and i. The extremities of the pin k lie in slots in
the operating handle 1, which is pivotted to the bracket m.
The
The operation of the cork drawer is as follows. As the handle 7 begins its
descent, the pink engages the doubly threaded upper portion of the hollow spindle b
and causes the corkscrew a to revolve in the nut f and to emerge therefrom and
pass into a cork which is held against the nut f. This much being accomplished,
the pin now enters the straight or longitudinal slots d in the spindle b, so that
the latter ceases to revolve. The pin k simultaneously comes in contact with the
lower end of the slot in the movable sleeve i, which is consequently pushed forward,
and, as its bell-mouth rests on the bottle shoulder, the bottle is forced away
from the cork. In the upward stroke of the handle the pink passes idly up the
straight slots in the spindle b and then enters the double screw threads c therein
and turns the spindle in the reverse direction, thus stripping the cork against the
nut f, the sleeve i being at the same time raised by the pin engaging with the
upper end of its slot 22. The sleeve i possesses four slots, namely two slots 2 and
two slots for the accomodation of the pins 9. The casing his slotted at h¹ to
accomodate the pin k.
Instead of the spindle 6 being hollow or tubular as above described, with threaded
and straight slots cut therein, it may be solid as shewn at Figure 5, Figure 6 being
a cross section of the spindle. With such a spindle I employ-as a substitute for
the pin a collar which surrounds the spindle and has trunnions which pass
through the sleeve and case h and enter the slots in the handle 7. Half embedded
in the inner surface of the collar, and diametrically opposite one another, are two
balls, which engage the threaded and straight grooves of the spindle.
Instead of the corkscrew a working in the nut f I may form a lower thread c¹
on the spindle b and I cause this thread to work in the nut f. The thread c¹ and
the corkscrew a have the same direction, the upper thread c having the reverse
direction. The operation of a cork drawer having a spindle similar to that shewn
in Figure 5 is practically identical, with that above described.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is:
1. The combination of a hollow spindle bearing spiral and straight slots and a
corkscrew working in a fixed matrix, a slotted containing case and a pivotted handle
carrying a cross-pin operating to turn the screw within its matrix so that it emerges
therefrom and enters a cork held against it, and a slotted sliding sleeve which is
thrust forward by said pin after the screw has entered the cork, whereby the bottle is

page_text: pushed from its cork, the spindle remaining stationary as the pin passes down
its straight slots, the reverse action serving to strip the cork against the fixed
matrix, substantially as described with reference to the drawings.
2. The employment in a cork drawer operating substantially as herein described,
of a spindle bearing right and left hand threads separated by straight grooves, and
a corkscrew, substantially as described with reference to Figures 5 and 6 of the
drawings hereto annexed.
