for the Invention of "IMPROVEMENTS IN CORKSCREWS.”
for the Invention of "IMPROVEMENTS IN CORKSCREWS.”
Sealed the 7th September 1875, and dated the 12th March 1875.
PROVISIONAL SPECIFICATION left by the said Hyde Bateman at the
Office of the Commissioners of Patents, with his Petition, on the
12th March 1875.
I, HYDE BATEMAN, of No. 2, Clifton Villas, Moore Park, Fulham,
in the County of Middlesex, Architect and Surveyor, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN CORKSCREWS," to
be as follows:-
This Invention relates to means by which in the continuous rotation
of the stem, as in piercing the cork, after such piercing has been fully
effected, the cork will be withdrawn; and my present improvements
relate to locking means to the handle of such stem, which locking means
is acted upon by the frame of the corkscrow to allow the handle to

page_text: operate on the stem and withdraw the cork when those parts come in
contact.
In effecting my improvements the lower part of the stem is provided
with any suitable penetrating and holding screw adapted to penetrate
and hold the cork to be withdrawn, and at the upper end of this
penetrating portion there is provided a collar or guide.
The upper portion of the stem above the collar is formed with any
suitable screw thread, but this portion of the stem is simply capable of
moving freely in the frame of the corkscrew without being acted upon
thereby, except for guiding that upper portion of the stem centrally into
the cork. Tho thread on this portion of the stem is cut to correspond
with a femalo screw in the handle of the stem; and this handle is
provided with a locking bolt or bolts, which during penetration locks
the handle and stem together, but so soon as penetration has been fully
effected this locking bolt or the bolts is or are released by coming in
contact with a conical or other suitable surface to the top of the frame,
and then the handle is capable of turning on the thread of this upper
portion of the stem, and in so doing of withdrawing the cork. So soon
'as the cork is withdrawn or the handle recedes from the frame it again
locks on to the upper portion of the stem.
I apply india-rubber or other suitable elastic substances to the edge
of the frame which bears on the bottle and to the outer surface of such

give and grant unto me, the said Hyde Bateman, Her special license that
I, the said Hyde Bateman, my executors, administrators, and assigns, or
such others as I, the said Hyde Bateman, my executors, administrators,
and assigns, should at any timo agree with, and no others, from time
to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the
and Isle of Man, an Invention for "IMPROVEMENTS IN CORKSCREWS," upon
the condition (amongst others) that I, the said Hyde Bateman, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner tho
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE,' that I, tho said Hyde Bateman, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
This Invention relates to means by which in the continuous rotation
of tho handle, as in piercing the cork, after such piercing has been.
fully effected the cork will be withdrawn; and my present improvements
relate to locking means to the handle of such stem, which locking means
is acted upon by the frame of the corkscrew to allow the handle to
operate on the stem and withdraw the cork when those parts come in
contact.
In effecting my improvements the lower part of the stem is provided
with any suitable penetrating and holding screw adapted to penetrate
and hold the cork to be withdrawn, and at the upper end of this
penetrating portion there is provided a collar or guide.
The upper portion of the stem above the collar is formed with any
suitable screw thread, but this portion of the steam is simply capable of
moving freely in the framo of the corkscrew without being acted upon
thereby, except for guiding that upper portion of the stem centrally into
the cork. The thread on this portion of the stem is cut to correspond.

Figure 3 shows another section of a portion of the same with the
parts in a different position from that indicated by the previous
Figures.
a is the frame, the lower edge a¹ of which in use rests on the upper
portion of the neck of the bottle from which the cork is to be with-
drawn; is the stem, the lower portion of which is provided with a
spiral penetrating means b¹, or other suitable means for penetrating the
cork; and d is the handle, which is provided with a pair or other
number of locking bolts e, the upper ends e' of which are supported each
to turn as on axes in the handle d, and are acted upon by springs c³
with a tendency to bear their lower ends towards the stem with their
projections or studs e into holes e' formed to receive those studs in the
upper portion of the stem b. When the studs e' of the locking bolts e
are in this position the handle & will be locked to the stem b, and by
turning the handled the penetrating portion of the stem will be
caused to penetrate the cork. In doing so the handle & will progressively
approach towards the upper rim or collar a of the frame a, the interior

page_text: of which collar forms a guide for the stem 6; and when the lower ends
of the bolts e come in contact with and as they bear against the upper
outer edge of the collar a³, as shown by Figure 3, those lower ends of
the bolts will be forced outwards, overcoming the force of their
springs c, and their studs e³ will then be released from the recesses e*,
and by acting in the thread 6 formed on the stem b act as a female
screw or corresponding thread, so that by continuing the rotation of the
handle & the stem 6 will be raised vertically to withdraw the cork from
the bottle.
Figures 4 and 5 show a slight modification of the arrangement shown
by Figures 1, 2, and 3, in which in place of the springs e² the upper
ends of the locking bolts e are acted upon by the V's or inclines 6* to
cause the studs e³ to pass into the holes e¹ in the stem b.
Figures 6 and 7 show another modification, in which the upper part e*
of the locking bolts e are extended in a somewhat horizontal direction
in recesses formed for them in the under side of the handle d, and they
are so extended as to act as weights to those ends with a tendency to
force the studs e into the holes e in the stem b, and retain them there
in place of using springs for that purpose, springs may however also be
used with this arrangement.
Figures 8 and 9 show another modification of the Invention, in which
and
the locking bolt e is applied in a recess formed for it in the stem b,
it is forced outwards with a tendency to project therefrom by an internal
spring. This bolt e when projecting beyond the surface of tho stem
rests on the under side of the bandle d, and thus prevents the screw
thread formed in that handle from following the course of the screw
thread formed in the surface of the stem until the inclined outer end
of the locking bolt e comes against the inner surface of the upper part
of the collar a², when the projecting end of that locking bolt e will be
pressed inwards so as to pass within the handle d, and will be there
held to admit of the screw thread in the handle d working on the screw
thread of the stem to raise the cork.
In each of the Figures of the Drawings the same letters apply to
corresponding parts wherever they occur.
Having thus described my Invention, and means which I adopt in
carrying the same into effect, I would have it understood that I do not

page_text: confine myself to the precise arrangements of parts as shown and
described, as the same may be varied without departing from the
peculiar character of my Invention, but what I do claim is, the
arranging or combining parts of corkscrews whereby locking bolts or
means e act to secure the motions for the penetration of the cork and
the withdrawal thereof from the neck of the bottle by the continuous
rotation of the handle, substantially as described.
In witness whercof, I, the said Hyde Bateman, have hereunto set
-
my hand and seal, this Eighth day of September, in the year
of our Lord One thousand eight hundred and seventy-five.
