page_text: I, HENRY HARDEMAN, of the Swan Hotel, Tenbury, in the County of Shrop-
shire, Gentleman, do hereby declare the nature of this invention to be as
follows:--
This invention relates as hereinafter described to an improved cork screw,
and has for its object to provide means whereby such articles may be rendered
more useful by providing means for allowing the gas to escape from a bottle
before the cork is drawn thereby preventing the over-flow of the liquor, and
waste thereof.
My invention consists essentially of a cork screw provided with an orifice or
tube whereby the gas may escape when the point descends beneath th bottom.
of the cork.
In carrying my invention into practice I make a cork screw somewhat of
the ordinary form and through part of the core of the screw threads I form a
tube in a manner whereby there is an outlet near the side of the point and another
near the top of the screwed part the one at the top of the threads, being the
educt.
Thus when the screw enters the cork by rotation and the point thereof des-
cends beneath the bottom the gas escapes through the tube aforesaid. The cork
can then be drawn without any danger of the liquor' overflowing, or the bottle
bursting in the hands.
I, HENRY HARDEMAN, of the Swan Hotel, Tenbury, in the County of Shrop-
shire, Gentleman, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
This invention relates as hereinafter described to an improved cork-screw
and has for its object to provide means whereby such articles may be rendered
more useful by providing means for allowing the gas to escape from a bottle
before the cork is drawn, thereby preventing the over-flow of the liquor and

page_text: waste thereof. My invention consists essentially of a cork-screw provided with
an orifice or tube whereby the gas may escape when the point descends beneath
the bottom of the cork. In carrying my invention into practice I make a cork-
screw somewhat of the ordinary form, and through part of the core of the screw
threads form a tube, in a manner whereby there is an outlet near the side of
the point and another near the top of the screwed part, the said' outlet constitut-
ing the induct for the gas, the one at the top of the threads being the educt.
Thus when the screw enters the cork by rotation and the point thereof descends
beneath the bottom, the gas escapes through the tube aforesaid: The cork can
then be drawn without any danger of the liquor overflowing, or the bottle
bursting in the hands.
In order that my invention may be more clearly understood I will describe
it by reference to the accompanying drawings, the same letters of reference
indicating similar parts throughout. Figure 1 illustrates a front elevation,
Figure 2, an end elevation and Figure 3'a vertical section of my improved
cork-screw.
A, represents the core of the screw and B, the tube. C and C are the induct
passages for the gas, and D, and D2, the educt passages for the gas. When the
corkscrew is driven into the cork E as illustrated at Figure 2, the passage C,
or Callows the gas to escape to the tube B and hence through the outlet D
or D and thus by reducing the pressure of the bottle's contents enables the
cork to be withdrawn without any danger of the liquor overflowing or the bottle
bursting. Should the liquor escape when the passages C and D are open, that
is to say before the cork is withdrawn and after the escape of the gas, a slight
turn of the screw will force the passage D³ into the cork, thus closing up the
same. My said invention in the manner herein before described may be applied
to the ordinary counter cork-drawer.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. The combination with a cork-screw of the central tube B, the induct pas-
sages Cand. Cand the educt passages D and D³ arranged to operate substan-
tially as described and illustrated' and for the purpose set forth.
Doted this 94th day of April 1900.
