PROVISIONAL SPECIFICATION.
Improvements in Stoppers for Bottles and Jars.
JAMES HARRAWAY, Tobacconist, 419, Brixton Road, London, S.W., ALBERT
SCUTT, Engineer, 48, Branksome Road, London, S.W., do hereby declare the
nature of this invention to be as follows:-

cork for securing the contents of liquids in bottles and jars consisting of three
or more lugs turned inwards at the bottom edge of cap to fit under the rim or neck
of bottle or jar.
Improvements in Stoppers for Bottles and Jars.
We, JAMES HARRAWAY, of 419, Brixton Road, London, S.W., Tobacconist, and
ALBERT SCUTT, of 48, Branksome Road, London, S.W., Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
1. Our invention relates to improvements in stoppers for bottles and jars.
2. The object of our invention is to improve the stoppers or caps used for
securing the liquid or other contents of bottles and jars, and in connection there-
with to improve the portions of the bottles and jars to which the stoppers or caps
are applied, in such a manner, that the stoppers or caps may be more conveniently
used and applied, and also, that the portion of the stopper or cap coming into
contact with the contents of the bottle or jar to which it is applied shall be made
of cork and used instead of a cork for securing the contents of the bottle or jar,
for which purpose, the aforesaid portion of the stopper or cap that is made of
cork may be brought into contact with and afterwards kept in sufficient contact.
with the mouth of the bottle or jar to which it is applied by the improved locking
arrangement to be hereinafter specified.
3. Referring to the drawing provided:-

stanner

page_text: Figure 2 shows a view in perspective of the improved stopper or cap.
Figure 3 shows a view in perspective of a portion of a bottle closed with the
improved stopper or cap.
Figure shows a section through an improved stopper or cap in place on the
mouth of a bottle.
4. Referring to Figure 1, a bottle is taken as an example of the application and
use of this invention. The neck of the bottle is formed as shown with one or
more grooves G, G, G, made in the thickness of the material of the neck, and the
grooves may be enlarged or widened at the upper or and lower ends as shown.
The grooves G, G, G, each terminate in a horizontal groove or channel HG,
HG, HG, which latter grooves do not form one continuous channel round the
neck of the bottle but are separated by the stops S, S, S. Sections of the
grooves HG, H G, are shown in Figure 4.
5. In Figure 2 is shown an external view of the improved stopper or cap ST.
It is made of metal, and fits easily over the mouth M of the bottle B as shown in
Figure 4. The lower edge of the stopper is provided with three or more
lugs L, L, L, projecting inwards as shown. Internally, the upper part of the
stopper is fitted with a disc of cork D, Figure 4, which disc is used instead of a
cork to close the bottle. The lugs L, L, L, may be formed by shaping them out
of the metal of the side of the stopper or cap, and then bending or turning them
inwards. Where greater strength is required, the lugs may be cut out from the
solid metal of the stopper or cap, or they may be formed separately, and soldered
on, or they may be cast in the proper position and of the proper shape in one
piece with the stopper or cap.
6. When the stopper ST is applied to the mouth of the bottle B for the purpose
of closing the bottle, the lugs L, L, L, are made severally to coincide with the
grooves G, G, G, otherwise the lugs L, L, L, would rest on the thicker portions
of the sides of the mouth of the bottle. The lugs L, L, L, being coincident with
the entrances to the grooves G, G, G, are now unobstructed and are free to

descend, and the stopper may be passed down over the mouth of the bottle.
referring to Figure 4, the downward movement of the stopper ST may be
continued until the cork disc D rests on the mouth of the bottle shown at M.
The disc D is of such a thickness that any further downward movement of the
stopper ST presses the disc D more and more tightly on to the mouth of the
bottle B until at last the lugs L, L, L, reach the respective horizontal
grooves H G, HG, H G, when a turn of the stopper ST to the right or left will
push the lugs L, L, L, along their respective horizontal grooves HG, HG, HG,
and the bottle will be safely stoppered. The movement of the lugs L, L, L, in
the grooves HG, HG, HG, is limited by the stops S, S, S, or by the ends of
the grooves HG, HG, HG.
It will

be there noticed that the sides of the stopper ST are in the same line as the sides
of the neck of the bottle. This enhances the neatness of the appearance of the
bottle. Such, however, is not an essential portion of this invention, but when
desired, it may be secured by increasing the external diameter of the bottle a
little below the grooves HG, HG, HG, as shown in Figure 4.
8. If the horizontal grooves HG, HG, HG, which are specified to be parallel
with the seating of the disc D on the mouth of the bottle B, are, starting from
their junctions with the grooves G, G, G, slightly inclined away from the mouth
of the bottle, the lugs L, L, L, of the stopper will by following the downward
direction of the grooves HG, HG, HG, tend still further to press the disc D
un to the mouth of the bottle.
9. On referring to Figure 4, it is obvious that the lugs L, L, L, of the stopper or
cap ST are retained or locked in position by the upper sides of the horizontal
grooves HG, HG, HG, and that the lower sides of the grooves are not used at all
for this purpose, therefore we may form the ledge or shelf required for retaining
the lugs by increasing the external diameter of the neck of the bottle at the

page_text: proper place to the required extent. This increase in the diameter if continued
up to the mouth of the bottle and forming a strengthening rim is present in most
bottles. And in order to adapt the rim so formed to the present invention, it
only remains to form the necessary grooves G, G, G, therein to pass the
lugs L, L, L, to the shelf on the underside and also where required to add the
stops S, S, S.
10. In other words, if instead of forming the horizontal grooves HG, HG, HG,
as specified, we reduce the external diameter, of the bottle as shown by the
dotted lines DL, DL, Figure 4, we form the shelf SH required for retaining the
lugs L, L, L, as before specified.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
A lock stopper or cap of metal with cork disc inside to be used instead of a cork
for closing the mouths of bottles and jars and for securing the contents of bottles
and jars whether liquid or otherwise, the stopper or cap being kept in position
by three or more lugs turned inwards at the bottom edge of the stopper or cap
and arranged to fit under the rim or neck of the bottle or jar to which it is applied
or into grooves formed in the neck of the bottle or jar and parallel with the mouth
of the bottle or jar, and with all necessary grooves or passages to enable the lugs
to reach the underside of the rim or the grooves aforesaid, all made and used
substantially as specified and described with reference to the drawings, and in
accordance to the modifications shown and described.
Dated this 10th day of January 1898.

ALBERT SCUTT.
