I, WILLIAM HENRY PARRY, of the Rock, Hagley, in the County of Worcester,
Builder, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in screw stoppered bottle openers. It
is found that with such bottles unless the stoppers are screwed up very tight, the
contents do not keep well; and that when thus screwed up tightly, and particularly
after standing some time, the stoppers are so fast that very considerable force has
to be used to unscrew them, and sometimes further results in a broken bottle..
To obviate these difficulties I have made this my invention.
I make a disc (preferably of hard wood) about twice the diameter (or more)
of the head of the stopper, and of a thickness 'say about half an inch to three
quarters of an inch. Upon the one side a concentric recess is made about three eights
of an inch or more, and of a diameter a little larger than the stopper head. At
the side in this recess I now provide a projecting tooth or catch or cam (of a ratchet
character) so that when the device is passed on to, the stopper head and turned in
the unscrewing direction, this tooth or catch or cam locks itself against the
periphery of the head and thus by the increased leverage, and convenient size of
the device, the stopper can be readily removed with ease.
The shape and fixing of this catch, or cam or tooth may be varied, and may
be formed of a pivotted like lever whose fore end may be notched or serated to
engage more surely with the head of the stopper, while its rear end is further
shaped that the catch may be moved in the one direction out of the way to admit
of the entrance of the stopper head, but when turned the other way it shall be
limited in its motion by coming in contact with a stop.
Instead of a pivotted catch I may make a spring-like catch which shall yield.
in the one direction, but not in the other, or a roller may be used in conjunction
with an inclined path, so as to tighten on to the head, when the device is turned
in the one direction or vice versa.

Improvements in Screw Stoppered Bottle Openers.
I, WILLIAM HENRY PARRY, of the Rock, Hagley, in the County of Worcester,
Builder, 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:-

is found that with such bottles unless the stoppers are screwed up very tight, the
contents do not keep well; and that when thus screwed up tightly, and particularly
after standing some time, the stoppers are so fast that very considerable force has
to be used to unscrew them, and sometimes further results in a broken bottle.
To obviate these difficulties I have made this my invention, and in order to more
fully explain this my invention I have appended hereunto an illustrative drawing
upon which are figures and numbers of reference, similar, numbers referring
throughout to the same thing or part.
Fig 1, is a plan view of this my invention.
Fig. 2, is a sectional view of the opener on line A-B, Fig 4.
Fig 3, is a sectional plan view of the opener on line C-D, Fig 2, as seen when
not in operation.
Fig 4, is a similar. view to. that of Fig 3, but showing the action of the cam
upon the bottle stopper.
Fig 5, is a "modification of my invention in which a spring catch is made to
serve in place of the cam.
Fig 6, is a modification of my invention in which a gripping roller is made to
serve as a can.
I make a disc 7; (preferably of hard wood) about twice the diameter (or more)
of the head 8, of the stopper shown in dotted lines, and of a thickness say about
half an inch to three quarters of an inch. Upon the one side a concentric recess 9,
is made about three eights of an inch or more, and of a diameter a little larger than
the stopper head. At the side in this recess I now provide a projecting cam 10,
preferably of a ratchet character, pivotted at 11, so that when the device is passed
on to the stopper head, as seen in Figs 2 & 4, and túrned in the unscrewing
direction as indicated by arrow 12, this cam 10 locks or jams itself against the
periphery of the head, and thus by the increased leverage, and convenient size
of the disc 7, the stopper can be readily removed with ease.
The shape and, fixing of this catch, or cam or tooth may be varied, as for instance,
instead of a pivotted catch I may make a spring-like catch 10", see Fig 5, which
shall yield in the one direction, but in the other, it shall bite upon or grip the
stopper as before described, or in some cases as shown in Fig 6, I may make the
inside surface 13, of an inclined shape so that as the device is turned in either
direction the roller 10b, shall be wedged upon the stopper head S, so that thereby
the stopper may be unscrewed. In this case, 14 is a plate having a slot hole 15,
through which the body of the roller may pass, but the removal of which is pre-
vented by the pivots 16. If desired the periphery of the roller and also the
surface 13, may be roughened or serrated so as to increase the bite.
It will be readily seen that the other side of the disc 7, may be utilized as a
push stopper opener.,
In this device it will be readily seen how convenient is the size and the circular
shape of the article which so readily affords means for a powerful action but yet
requiring but a simple movement in application.
'
my
said
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what I
claim is:-
In screw stoppered bottle openers the combination with a disc 7, having a
recess 9, of the tooth, cam, or roller such as 10, 10", 10", constructed and operated
substantially as set forth and shown.
