other Vessels.
LIONEL DOVE, of 37 Liverpool Street Bishopsgate Street, in the City of London
Engineer, do hereby declare the nature of my said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement:-
The object of my invention is to effect improvements in stoppering or closing
bottles, jars, and other vessels of a similar nature.
In this Specification the word "bottle" is intended to be read as including jars
and other vessels.
In carrying out my invention I provide inclined planes round, or partially round
either the inside or the outside of the neck of the bottle, at or near the mouth of
the same. I prefer to form two of such inclined planes, with a short break between
them, on opposite sides; but any other number may be formed therein or there-
upon, according to the nature of the article or vessel; and, for the purpose of
description, I shall confine myself to two inclined planes only.
The stopper is formed with two studs, nibs, or lugs, either inside or outside,
according to the construction of the neck of the bottle." These studs are capable of
passing between the ends of the inclined planes, and engaging their undersides,
after the manner, or on the principle of bayonet joints.
Suitable packing of india rubber, cork, or other elastic substance, is provided, in
order to render the stopping air and liquid proof.
And in order that my said invention may be more particularly ascertained
and described, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
Fig. 1 is an elevation of the upper part of the neck of a bottle parallel to the
line 1-2 of Fig. 3. Fig. 2 is a similar elevation parallel to the line 3-4 of
Fig. 3.
Fig. 4 is a vertical section on the line 1-2 of Fig. 3. Fig. 5 is a similar section
on the line 3-4 of Fig. 3.
Fig. 6 shews in section on the line 5-6 the cap in its place, and Fig. 7 is
a section of the ordinary form of cap.
The remaining figures shew variations of construction.
a is the upper part of the neck of a bottle, b b are inclined planes or wedge
pieces, formed in one with the bottle. cc are two stops, to prevent the cap from
being turned too far, in closing the bottle.

then turned to the right or left, which operation causes the lugs ff to become
locked and firmly held under the inclines bb The top of the cap d (Figs. 6 and 7)
is lined with a suitable packing of cork, india rubber, or other elastic substance,
which is firmly pressed against or upon the upper edge or mouth of the bottle, and
forms a fluid-tight joint.
Another form of cap is shewn in Fig. 8, in which the packing e consists of a ring,
surrounding the projection d' which enters the mouth of the bottle.
Figs. 9 to 14 shew the application of my invention to the inside of the neck.
Fig. 11 is a section 6' 6 being the inclined surfaces under which the lugs f1, Fig. 9,
are secured d, Fig. 9, is the head of the stopper, e is the packing ring and f¹, is
one of the lugs. Fig. 10 is a view of the underside of Fig. 9.
Figs. 12 and 13 shew two methods of fitting the packing to the mouth of the
bottle, instead of the stopper. In Fig. 12 a ring or band e of circular section is
shewn, and in Fig. 13 a band of square section is shewn, let into a wedge shaped
groove.
Fig. 14 is a section on the line 7-8 of Fig. 11, shewing the inside channels b² 62
and the stops c¹ c¹.
It is obvious that the positions of the lugs and wedge pieces may be reversed,
and the lugs placed on or in the neck of the bottle, the wedge surfaces being placed
in or on the stopper.
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 manufacture and use of bottles, jars, and other vessels, and of stoppers
for the same, constructed, arranged, and operating substantially as hereinbefore
described and shewn on the drawings.
2. The general arrangement, construction, and combination of the several and
respective parts, together forming my improvements in stoppering or closing
bottles, jars, or other vessels, substantially as herein before described and shewn on
the drawings.
