WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. 'IMPROVEMENTS IN BOTTLE STOPPERS." [A
communication from abroad by Charles Otto Hammer, of Pittsburg, Pennsylvania,
United States of America.]
This Invention relates to improvements in bottle stoppers, and consists in a cone-
shaped clastic stopper secured to a metallic cap hinged to a lever, and the lever
hinged to the neck of the bottle by means of a curved extended piece or bail
pivoted in lugs on a band surrounding the neck of the bottle, whereby the elastic
stopper may be pressed into the mouth of the bottle through the medium of excentric
action of the said lever, and withdrawn through the medium of the said lever. The
said band is divided, and the two ends are bent back so as to form loops for the
purpose of drawing the band closely to the neck of the bottle by means of a link
formed of wire, the tightening being effected by twisting the wire.
In case of the bottle being broken by accident the band may be opened out by
untwisting the wire, and then its bail, lever cap, and stopper can be removed from
the neck of the broken bottle.
Instead of employing the aforesaid band I may in some instances form a socket
on each side of the neck of the bottle, into which the bail will be pivotted..

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN BOTTLE STOPPERS." A
communication from abroad by Charles Otto Hammer, of Pittsburgh, Pennsylvania,
United States of America.
My Invention relates to improvements in bottle stoppers or stopples, and consists
in a coni-formed elastic stopplo secured to a metallic cap hinged to a lever, which
is hinged to the neck of the bottle by means of a bail pivotted in the lugs of a band
surrounding the neck of the bottle, whereby the said elastic stopple may be pressed
into the mouth of the bottle through the medium of the excentric action of the
lever, and withdrawn through the medium of the said lever.
In the accompanying Drawing,
Figure 1 is an elevation of the bottle provided with my improved stopple,
representing the stopple, the lever, and bail in the position they occupy when the
bottle is sealed.
Figure 2 shews the position of the said lever, bail, and stopple when the bottle is
unsealed.
Figure 3 is a vertical section of the lever, cap, and coni-formed stopple.
Figure 4 is a sectional view, shewing these parts in the same position as in
Figure 2.
Figure 5 is a side elevation, representing the bail pivotted in the neck of the
bottle, according to a modification of this Invention.
Like letters indicate corresponding parts throughout the Drawing.
A represents the bottle, around the neck of which is placed a band B, having
lugs C, in which are pivotted a bail D; the latter passes through the lever e, which
is pivotted at f to the metallic cap g, to whose under side is secured the elastic coni-
formed stopple h. The band B at i is so bent back as to form loops for the
purpose of drawing the said band closely to the neck of the bottle by means of a 3
link formed of wire by twisting it, as shown at m.
In the event of the bottle being broken the said band, by untwisting the part m
of the link, may be opened out, and its bail, lover, cap, and stopple can be removed
from the neck of the broken bottle.
The form of the device shown in Figure 5 is a modification of my Invention, as
shewn in the other Figures of the Drawing, and may be substituted for the same.
In this modification, instead of using the band, I form sockets or holes at q in the
sides of the bottle neck for the reception of the ends of the bail.
The operation of the said Invention is as follows, that is to say:-The elastic
coni-formed stopple h is placed in the mouth of the bottle, and the lever e is thrown 4
from the horizontal position, represented in Figure 4, to the vertical position shown
in Figures 1 and 3, the said lever having an eccentric action, whereby the stopple
is so pressed down into the mouth of the bottle as to hermetically seal it, and hold
it in a locked position.
Having thus fully described the said Invention, as communicated to me by my 4
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim,
First. The combination of the bail, the lever, the cap, and the stopple, arranged
and operating with relation to oach other, as herein described, and for the purpose
set forth.
Second. The combination of the band, the bail, the lever, the cap, and the stopple,
arranged and operating as herein described, and for the purpose set forth.
Third. The band having hooked ends in combination with the link, the bail, the
lever, the cap, and the stopple, as and for the purpose set forth.

page_text: Fourth. A bottle provided with sockets or holes in its neck for the reception of
the ends of the bail, as above set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Eleventh day of November, in the year of our Lord
One thousand eight hundred and seventy-eight.
