Improvements in and relating to Devices for Hermetically
Closing Bottles, and for similar Purposes:
I WILLIAM ROBERT LAKE of the firm of Haseltine Lake & Co Patent Agents
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN AND RELATING TO DEVICES FOR
HERMETICALLY CLOSING BOTTLES AND FOR SIMILAR PURPOSES," to be as follows:-
This invention relates to stoppers for bottles or other vessels, and to the mode of
fastening such stoppers.
The said invention comprises essentially a cap which is applied hermetically to
the mouth or orifice of the vessel by causing a bolt with a lever to act upon a cam
on the closing disc.
My system is susceptible of various modifications and applications as hereinafter
described.
According to this invention, I provide a cap which is connected by a vertical bolt
with a collar fixed upon the neck of the bottle, the said cap being hinged or pivotted
to the upper end of the said bolt. The collar consists of two semi-circular parts
fastened to the vertical bolt and united by a screw. A projection on the collar
receives a second vertical bolt provided with a lever and having at its upper
extremity a lug. In an extension of the cap is formed a hole adapted to permit
the upper part of the said second vertical bolt to pass therethrough, the cap being
closed upon the mouth or orifice of the bottle, and the extremity of the bolt passed
through the hole in the said extension; the bolt, when turned by the lever, causes
the lug to slide or turn upon the inclined face of the extension and press the cap
firmly against the mouth of the bottle. In order to ensure tightness the cap is
provided with an india-rubber disc or ring in the interior.
According to a modification one half of the collar is dispensed with and replaced
by a wire which is fastened in recesses formed in the two ends of the collar.
According to another modification the collar does not extend all around the neck
of the bottle, being secured to the bottle simply by its elasticity. It is placed on

page_text: the neck of the bottle by bending its two ends asunder and it is held there in
consequence of its action as a spring.
When I employ the improved stopper with bottles for aerated drinks the cap
is provided with a central orifice which is normally closed by an india-rubber
valve.
For short necked bottles or vessels with a large orifice, the aforesaid metallic cap
is substituted by a ring which presses a glass plate against the india-rubber disc or
ring placed upon the edges of the mouth of the bottle, thus ensuring the tightness
as desired.
"
I may employ the improved stopper in connection with lamp-burners, in which
case I provide a cylinder which is secured 'upon the reservoir for the combustible
liquid, and the cap above it, which receives the burner, by the action of the cam
mechanism described above, presses an india-rubber ring placed in an annular
groove formed in it against the edges of the said cylinder. In order to introduce
the oil or other combustible liquid it is sufficient to turn the lever bolt so as to
disengage the cap from the lug and to turn the cap around.its pivot.

I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my invention for "IMPROVEMENTS IN AND RELATING TO DEVICES FOR HER-
METICALLY CLOSING BOTTLES AND FOR SIMILAR PURPOSES" and in what manner.
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention relates to devices chiefly designed for hermetically closing
bottles.
The said invention comprises a device consisting of a bolt formed with snugs or
projections and designed to be partially rotated by a lever to operate in combination.
with helical or inclined surfaces upon à cap and upon a lug secured to the neck of
a bottle or upon other parts so that the said parts will be forced towards each other,
and a tight joint, between the same thus ensured!
In some cases, the bolt has a snug or projection at one end to operate in
combination with an inclined surface on one of the parts, and its other end, is
formed with an external screw-thread' to operate in combination with a, corre-
sponding internal screw-thread in the other of the parts to. be united or secured
together.
The said invention, moreover, comprises various improvements as hereinafter set
forth.
The improved devices are susceptible of various, modifications, some of which are
hereinafter described with reference to the accompanying drawings.
Figure 1 is a side elevation, partly in vertical section.
Figure 2 a front elevation, and
Figure 3 a plan, shewing the neck of a bottle provided with devices made in'
accordance with the said invention.
C
In these Figures, A. indicates a cap, which is connected by a bolt B with a
collar C'secured upon the neck of the bottle. The cap A is hinged or pivotted at ✗
to the upper end of the bolt B. The collar C is formed of two semi-circular parts
connected by the bolt B and by a screw D. The lug or extension' E on the said
collar is screw-threaded internally to receive a screw-threaded bolt F provided with
a lever F, and having.at its upper extremity a snug or projection' H
The cap A is provided with a lug or extension I having a helical or inclined
surface on its upper side and formed with a hole I to receive the upper part of the
bolt F, the upper end of the said bolt can, however, only be passed through the
said hole when the lever and bolt are in the position-indicated by dotted lines in
Figure 3.
When the cap A is turned on its hinge into position to close the orifice or mouth
of the bottle, and the upper extremity of the bolt is passed through the hole 1, the
cap A can be forcibly pressed against the mouth of the bottle by turning the bolt F

page_text: by its lever F into the position shewn in full lines in Figure 3, the snug or
projection H sliding up the helical or inclined surface of the lug or extension I, and
the helical surfaces of the screw-thread on the lower end of the bolt F acting in
combination with the correspondingly inclined surfaces of the screw-thread in the
lug or extension E.
A disc, ring or washer K of india-rubber or other suitable elastic material is
inserted in the cap A, so that it will press upon the neck of the bottle and ensure
the closing of the same hermetically.
Figure 4 is a plan showing a modification which consists in dispensing with one
half or part of the collar C and replacing it by, or substituting for it, an iron wire
which is fastened in recesses a, a.
Figure 5 is a plan shewing another modification which consists in making an
incomplete spring collar C designed to be secured or held upon the bottle-neck by
its elasticity. When the ends b, c are opened or pulled apart and the bottle is
introduced into the collar, the latter, by reason of its elasticity, presses against the
neck of the bottle.
Figure 6 shows a device for closing bottles for containing aerated liquids; in
this device, the cap A is provided with an orifice M to which an india-rubber or
other valve N is applied.
Figure 7 represents the application of my invention to a short necked bottle or
vessel with a large orifice. The said Figure also illustrates a modification which
consists in substituting for the screw-thread at the lower part of the bolt E and in
the lug or extension E, a snug or projection H¹ on the bolt and a helical or inclined.
surface on the said lug or extension, similar to those above described.
:
The part A, instead of being in the form of a cap, is made in the form of a ring.
which, when acted upon by the bolt F, presses a glass plate O against the elastic
ring or washer K and thus forces the same against the edges of the bottle-neck and
ensures the tight closing of the bottle.
It is obvious that the device consisting of the bolt provided with the snugs or
projections and arranged to operate in combination with helical or inclined
surfaces as above specified can be employed for other purposes than the closing
of bottles.
For example, it can be applied to lamps, as shewn in Figure 8, for the purpose
of making a tight joint between the lamp-burner and the vessel for containing the
oil or inflammable liquid. In this Figure, a cylindrical piece R is firmly secured
in any suitable manner upon the reservoir or vessel for the inflammable or com-
bustible liquid, the part A, which is made in the form of a ring and in which is
fitted the burner S, is applied to the said cylindrical piece R in a similar manner
to that above described, an elastic ring or washer K being placed in an annular
groove formed in the part A.

In order to introduce the oil or other combustible liquid, it is sufficient to turn.
the bolt F by means of the lever F¹ and thus release the part A from the snug or
projection H, and then to turn the part A and burner S around or about the
pivot X.
+
The said bolt operating in combination with helical or inclined surfaces can also
be employed for ensuring the tightness of joints between pipes, as shewn in
Figures 9 and 10, or Figures 11 and 12, or Figure 13, the bolts being formed either
with two snugs or projections H, H', one at each end, as shown in Figures 9 to 12,
or with a snug or projection at one end and a screw-thread at the other end, as
shewn in Figure 13.
Figures 14 to 17 shew further modifications of the improved devices as applied.
to bottles or other vessels. These modifications will be readily understood without.
further description.
If desired, the lever F1 above described may be dispensed, with and the bolt: F
formed with a hexagonal head or otherwise so that it can be turned by means of a 5
spanner
