"IMPROVEMENTS IN CORK-SCREWS."
This Invention consists in constructing a body or case to fit over the neck of the
bottle. The screw passes down the centre of this body or case. Upon the case are
two projecting arms, to which are pivotted two levers; below the head or thumb
piece of the screw is a projection, collar, or boss. By screwing the screw into the
cork this projection, collar, or boss is brought to bear upon the levers and throws
them into a horizontal position. To draw the cork it is then only necessary to
press downwards simultaneously the arms of the levers.

* IMPROVEMENTS IN CORK-SCREWS."
This Invention consists in constructing corkscrews with a body or case to fit
over the neck of the bottle. The screw passing down through the centre of the
case. Projecting from the sides of the case are two arms, to each of which is hinged
or pivotted a lever; below the head or thumb piece of the screw is a projection,
collar, or boss, against which the lever arms are brought to bear in order to raise
the screw and thus draw the cork-out-of-the-bottle.-
Referring to the Drawings, Figure 1 is a front view of the corkscrew, and
represents the position of the several parts when the screw is inserted in the cork;
Figure 2 is a side view; and Figure 3 a front view of the corkscrew, and represents
the position of the parts when the cork has been withdrawn from the bottle.
(a), (a), are the two arms; (b), (b), the levers; (c), the projection, collar, or boss.
By screwing the screw into the cork the projection, collar, or boss (c) is brought
to bear upon the two levers (b), (b), and throws them into the position shown in
Figure 1. To draw the cork it is then only necessary to press down the
ends (d), (d), of the levers (b), (b), until they are in the position shewn in Figures 2
and 3.
Figure 4 shews a modification of the Invention, in which modification a loose
boss (e) is allowed to work up and down the shaft-of the-screw, and upon this loose
boss are two pins, one of which is shewn at (f) working in slots (9) in the levers.
The pressing down of the levers causes the loose boss to slide up the shaft, and in
so doing to press against the head or thumb piece and withdraw the cork from the
bottle.
By another arrangement the levers may be hinged to the head or thumb piece
instead of to the arms or projections upon the sides of the case. These arms or
projections simply acting as fulcrums for the levers.
Having thus described the nature of the said Invention and the manner in which
the same is to be performed, I claim, without limiting myself to these precise details,
the application of two levers to corkscrews in the manner and for the purposes
herein more fully set forth and specified.
In witness whereof, I, the said William Burton Baker, have hereunto set my
hand and seal, this Fourteenth day of January, in the year of our Lord
One thousand eight hundred and eighty one.
