COMPLETE SPECIFICATION.
Improvements in Means for Stopping Bottles, Jars, and other
Vessels.
I, IGNATZ MARTIN of 1155 Myrtle Avenue, Brooklyn, Kings County, New
York, United States 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 :-
This invention has for its object to firmly close and readily unclose the mouths
of bottles, jars and other vessels, without danger of losing the stopping device, and
to these ends the bottle and its stopper are constructed as fully described in
the following Specification and illustrated in the accompanying drawing, in
which ;-
Fig. 1 is a perspective view, showing my improvement as applied to the top of a
bottle.
Fig. 2 is a cross sectional elevation.
Fig. 3 is an inverted view of the stopper, showing one form in which it may be
made.
Fig. 4 is a sectional view of the stopper, showing a modification.
A represents the neck of a bottle, jar or jug, which may be of any suitable size,
contracted as shown, in the case of a bottle or it may be expanded in the case of a
preserving or other vessel.
The neck of the bottle or jar is provided with an enlargement a which has in it two
vertical grooves & s¹, each terminating at the top in an angular section t, making
something like the groove of a bayonet joint.
The lower edges y y' of the enlargement on opposite sides of the grooves s s' are
inclined, the edge y being inclined from the lowest point 2 at the side of one groove
to a higher point 3 at the side of the upper groove; while the edge y¹ is inclined
from the lowest point 4 at the side of the groove s¹ to the higher point 5 at the sile
of the groove s.
The stopper B consists of a cap, disc or top f of any suitable form with two
pendent legs bb, and at the end of each leg is an inwardly projecting lug or
trunnion c.
These parts are so constructed that when the stopper is applied to the
bottle, the lugs are passed beneath the edges y y¹ of the enlargement a and into
the grooves s s¹, and by turning the stopper in the direction of the arrow, Fig. 1,
the lugs c are gradually carried beneath the deeper portions of the inclined
edges y y¹ until the cap f is drawn down close upon the neck of the bottle firmly
holding it in place against the neck or against any intervening packing which may
be placed there if desired. When it is desired to hold any liquids under pressure
in the bottle, a cork may be placed in the bottle and then the stopper may be
forced down and turned as before described so as to hold the cork in place.
When it is desired to release the contents of the bottle, the stopper B is turned in
an opposite direction to the arrow, Fig. 1 until it is gradually released and the lugs
are brought into the grooves ss when the cap is raised and then swung over to one
side, the lugs turning in the portion t of the grooves so that they act as trunnions
upon which the cap may swing without being released from the bottle. The
contents may then be poured out unless the bottle is corked, if the bottle is corked,
then the cork may be removed and the contents then discharged.
The grooves ss may be of any desired width but preferably there is only just
sufficient width to permit the lugs ce to pass upward without permitting the same

page_text: to be turned in the grooves until the lugs reach the portion t of the grooves. The
stopper therefore is always held in connection with the bottle unless the legs are so
sprung apart as to permit it to be released, which however is seldom required.
If desired, the edges y y¹ may be serrated so as to form projections or shoulder>
against which the edges of the lugs cc may catch to prevent the stopper from being
too readily turned.
The engaging edges of the lugs c may be inclined as shown to correspond to
similar inclinations of the shoulders or edges y y', so as to prevent the legs from
spreading apart and disengaging from the bottle when the cap is held in place.
If desired the stopper may be provided with flanges ee which tend to maintain it
centrally in position upon the top of the bottle or jar.
The stopper B may be made of cast or any other suitable metal or material;
I prefer however to strike it up from a sheet of sheet metal, forming a central
dise, and two projections which when folded up form the legs bb, each leg being
folded centrally and the parts brought together to form the lugs c c.
As said before, there may be a packing. If there is such a packing 1 prefer to
make use of the construction shown in Fig. 4 where the cap is formed with a
pocket to receive a block of rubber g and is compressed or indented before or after
introducing the block so as to hold the same in place; and if desired the cap may
be cut away as for instance above the point 7, leaving the upper portion of the
rubber block projecting through. I thus am enabled to combine the stopper
permanently with the cap. When a rubber disc is used between the stopper and
the top of the bottle, I prefer in many instances to put a metal plate under the disc
to facilitate the turning of the stopper.
It will be evident that the various parts of the structure may be altered in
then proportions and dimensions while still preserving the main features of the
invention.
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 1
claim is ;-
1. A bottle having an enlargement a and the edges y y¹ and grooves & s' having
lateral portions t combined with a stopper having a cap portion and dependent legs
and lugs entering the grooves all substantially as set forth.
2. A bottle provided with an enlargement a having cam edges and vertical
grooves having lateral portions at the top combined with a stopper having pendent
legs and lugs adapted to said grooves and adapted to be moved vertically upward
above the top of the bottle and swung to one side or to be depressed and turned
to engage its lugs with the inclined edges to hold the cap in place substantially as
set forth.
3. The combination with a bottle having an enlargement and inclined edges y y¹
and vertical grooves with lateral portions t of a stopper consisting of a cap formed
of sheet metal with extensions bent at an angle to the top and folded to form
legs and lugs c c substantially as set forth.
4. The combination of the bottle having the enlargements with inclined edges
and grooves of a stopper having pendent legs and lugs and provided with a rubber
packing or stopper with or without a metallic plate or washer substantially as
set forth.
5. The within described improvement in means for stopping bottles jars etc.
comprising an enlargement upon the bottle or jar with inclined edges and grooves
and a stopper having pendent legs and lugs all constructed and arranged to operate
substantially as described.
