PROVISIONAL SPECIFICATION.
Improvements in Means for Opening Internally Stoppered Bottles.
I, CORNELIUS CRASTIN, of 88, Blackstock Road, Finsbury Park, in the county
of London, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to means for opening bottles which are closed with internal
stoppers.
In carrying out my invention I provide a block having a central plug or projection
the diameter of which decreases towards the base, and a raised flange situated at a
suitable distance around the said plug, the face of the said plug being preferably
made concave to especially adapt it to the surfaces of ball stoppers. The block is
advantageously formed so that it can be fixed at an acute angle to the front edge of a
counter or to the under side of the same. The central plug or projection is provided
with a passage for the escape of gas from the interior of the bottle. Within the
recess between the plug or projection and the flange I place an india rubber or other
suitable washer against which the mouth of the bottle comes in contact when the
bottle is opened and which is made with a corrugated face so as to allow of the
escape of gas from within the bottle.
In order to open an internally stoppered bottle with an opener of this construction
it is only necessary to place the mouth of the bottle over the plug or projection and
then to press the bottle, whereupon the plug will force the stopper into the bottle
and the mouth of the latter will press against the corrugated washer, the gas passing
out through the corrugations of the same and through the hole in the plug or pro-
jection, thus preventing any waste of the contents of the bottle. By forming the plug
with inclined eides in the manner hereinbefore described bottles can be opened
whether they are pressed against the opener in a straight line or at an angle without
any risk of breaking the bottle.

COMPLETE SPECIFICATION.
Improvements in Means for Opening Internally Stoppered Bottles.
I, CORNELIUS CRASTIN, of 88, Blackstock Road, Finsbury Park, in the county of
London, Engineer, 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 :-
My invention relates to means for opening bottles which are closed with internal
stoppers.
In carrying out my invention I provide a block having a central plug or projection
adapted to enter the mouths of bottles, and a raised flange situated at a suitable
distance around the said plug, the diameter of the said plug decreasing towards the
base and the face being preferably made concave to especially adapt it to the surfaces
of ball stoppers. The block is advantageously formed, so that it can be fixed at an
acute angle to the front edge of a counter or to the underside of the same. The
central plug or projection is provided with a hole or passage for the escape of gas from
the interior of the bottle. Within the recess between the plug or projection and the
flange I place an india-rubber or other suitable washer with which the mouth of the
bottle comes in contact when the bottle is opened.

page_text: In order to enable my invention to be fully understood 1 will describe how
it can be carried into practice by reference to the accompanying drawing in
which :-
Figure 1 is a front elevation:
Figure 2 is a side elevation; and
Figure 3 is a section of a bottle opener constructed according to my invention,
shewn fixed to the vertical face of a counter or the like; the two latter figures also
illustrating the application of
bottle when using the opener.
Figure 4 is a similar view to figure 2 but shewing the bottle opener fixed to the
underside of a counter or the like.
Similar letters in all the figures indicate similar parts.
a is the block which is advantageously formed of a hollow casting as shewn
provided with lugs b, b to allow of it being readily screwed at any angle to the front
of a counter c, as shewn in figures 1, 2 and 3, or to the underside thereof as in
figure 4, and with a hole d for the passage outwards of the gas from the bottle being
opened.
e is the central plug or projection formed on the hollow block a and having a
diameter decreasing towards the base, a concave face fto especially adapt it to the
surface of ball stoppers and a central hole g leading to the interior of the block a and
transverse groove for the passage of the gas from the bottle.
i is the flange formed on the block a at a distance from and around the plug e; j is
the washer placed in the recess between the plug e and flange i and with which the
mouth of the bottle comes in contact.
In order to open an internally stoppered bottle with an opener of this construction
it is only necessary to place the mouth k of the bottle, illustrated by dotted lines in
figures 2 and 4, over the plug e and then to press the bottle against the opener, where-
upon the plug will force the stopper into the bottle and the mouth of the latter will
press against the washer j, as shewn in figure 3, the gas passing through the
groove h and hole g in the plug to the interior of the block a and then out through
the hole d, thus preventing any waste of the contents of the bottle.
The plug e formed with inclined sides in the manner hereinbefore described and
illustrated constitutes the main feature of my invention, the advantage arising from
this formation being that bottles can be opened whether they are pressed against the
opener in a straight line or at an angle without any risk of breaking the bottle, there
being always a clearance between the base of the plug and the interior of the bottle
mouth (as will be seen by reference to figure 3) which will allow the bottle to be
turned or pressed askew to a certain extent without risk.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The improved means for opening internally stoppered bottles hereinbefore described
with reference to the accompanying drawing.
