Improvements in and relating to Cork-screws or Extractors.
We, ALEXANDER EDIE, Machinist, HERMAN KOPPAS and JOHN NICK KOPPAS,
Builders, all residing at Butte City, in the County of Silver Bow and State of
Montana, one of the United States of America; do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to cork-screws; and consists of the novel features which will
hereinafter be more fully described and claimed and shown in the annexed drawing,
in which-
Figure 1, is a side view of a cork-screw embodying our invention;
Figure 2, is a vertical section about on the line, X-X, of Figure 1, on an enlarged
scale;
Figure 3, is a detail view of the upper portion of the frame showing the toothed
lever in position ;
Figure 4, is a top plan view of the frame, and-
Figure 5, is a sectional view of the enclosed end of the screw cylinder, on the
line, Y-Y, of Figure 3.
The frame comprises the upper tubular portion, a, the lower collar or ring, a¹, and
the bars, a², connecting the parts, a, and, a'.
The toothed levers, B, are arranged in grooves in the sides of the tubular portion, a,
and are pivoted between their ends to the sides of said tubular portion. The lower
ends of the levers, B, are connected by the spring, C, which is semi-circular and
adapted to press the ends of the levers together. The upper ends, b, of the levers, B,
are bevelled from one side to the other for the purpose hereinafter more particularly
described.
The levers are reduced in thickness below the portion, b, to form the shoulder, b¹,
and the upper end of the tubular portion, a, is reduced to form the stop or
shoulder, d, which limits the downward movement of the ring, D, relative to the
frame, A.
The screw, E, is fastened at its upper end to the externally threaded stem, F, which
is provided with the crank, f, or other handle at its upper end for rotating the stem, F,
and screw, E.
The cylinder or case, G, is fastened at its upper end to the stem, F, and is adapted
to encircle the tubular portion, a, of the frame, a space, y, the width of the ring, D,
being left between the sides of the casing, G, and the tubular portion, a, for the said
ring, D, to work in. The inner flange or shoulder, h, at the lower end of the case
fits the tubular portion, a, snugly and steadies the said case and stem, F, in their
movements, and forins a stop for the ring, D, to strike against and disengage itself
from the frame and the shoulders, b', of the levers, B.
The device is supported on the end of a bracket, I, which is secured to a counter,
table, shelf, or other support. To remove a cork place the bottle at the end of the
screw or frame and rotate the stem, as the screw enters the cork the stem and case
descend until the closed end of the case rests on the top of the levers, B, when the
cams, j, at said end of the cylinder, G, will engage with the inclined or bevelled
ends, b, of the levers and press them in and bring the teeth thereon in engagement
with the thread on the stem, at the same instant the ring, D, will drop over the
shoulders, b', of the levers and hold the toothed ends of the levers in engagement with
the thread of the stem, F. The stem and case are rotated in the same direction and
are caused to rise by reason of the teeth on the levers, B, engaging with the thread
on the stem, F, thereby extracting the cork which is carried up with the rising
screw. When the case reaches a certain elevation, which is sufficient to remove the

page_text: cork, the ring, D, strikes the shoulder or stop, h, and is disengaged from the levers
and the spring, C, reacting presses the lower ends of the levers together and
disengages the toothed ends of the said levers from the threaded steni, F. The
stem and case being released will fall and be in position to repeat the operation
above described.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is―
First In a cork-screw, the combination with the frame and the screw having a
threaded stem, of toothed levers carried by the frame and adapted to be thrown in
engagement with the thread on the stem, and means, as the ring, D, for locking
the levers when in engagement with the said thread, substantially as described.
Second The combination, in a cork-screw, of the frame, a threaded stem journalled
in the frame and having screw, E, at its lower end, and cam, j, at its upper end
toothed levers pivoted to the frame and operated by cams, to throw them in
engagement with said threaded stem, a spring for throwing the levers out of
gear with the threaded stem, and a locking ring, D, substantially as described.
Third: In a cork-screw, the combination of the frame, the threaded stem and the
toothed levers, of the cams, j, for throwing the levers in engagement with the said
stem and the locking ring, and the spring, C, substantially as described.
:
Fourth In a cork-screw, the combination with the frame and the toothed levers,
of the threaded stem carrying the screw, the case having the inner flange or
shoulder, h, and having the cams, j, and the locking ring, D, and the spring, C,
substantially as described.
Fifth The herein shown and described cork-screw composed of the frame, the
toothed levers, B, the spring, 0, the threaded stem, F, having the screw, E, the
case, G, having the cams, j, and the inner flange, h, and the locking ring, D, substan-
tially as and for the purpose described.
