IMPROVEMENTS IN STOPPERING JARS, BOTTLES, 'AND OTHER VESSELS.CONTAINING ALIMENTARY AND OTHER SUBSTANCES:
Year: 1879

page_text: LETTERS PATENT to William Howard Allen, of Cubitt Town; in the County of
Middlesex, for the Invention of "IMPROVEMENTS IN STOPPERING JARS, BOTTLES,
'AND OTHER VESSELS.CONTAINING ALIMENTARY AND OTHER SUBSTANCES:"
PROVISIONAL SPECIFICATION left by the said William Howard Allen at
the Office of the Commissioners of Patents on the 27th September 1879.
WILLIAM HOWARD ALLEN, of Cubitt Town, in the County of Middlesex.
"IMPROVEMENTS IN STOPPERING JARS, BOTTLES, AND OTHER VESSELS: CONTAINING
ALIMENTARY AND OTHER SUBSTANCES."
The object of this Invention is to effect a thorough and convenient closure, while
at the same time preventing air from being compressed into the jar or. other vessel
while the stopper is being inserted.
I:form the stopper with a projecting part or rim slightly smaller than the neck.
or upper inside part of the jar, and I place an elastic ring, say of india rubber,
around. this rim so as to form an airtight joint when inserted in the jar. I form a
small hole through the upper part of the jar at such a distance from the top that
the air enclosed in the jar can escape thereby while the stopper. is being inserted,
but.so as to be covered by the elastic ring when the stopper is fully inserted.
. Or I may reverse the construction by fitting. the elastic ring on the outside of the
jar and fitting the lid over the same, and forming the lid with a small hole for the
escape of the air.
"
This lid or stopper may be conveniently removed and put on airtight again as
often as desired.

by the said William Howard Allen in the Great Seal Patent Office on the
27th March 1880.
WILLIAM HOWARD ALLEN, of Cubitt Town, in the County of Middlesex.
"IMPROVEMENTS IN STOPPERING JARS, BOTTLES, AND OTHER VESSELS CONTAINING
ALIMENTARY AND OTHER SUBSTANCES."
The object of this Invention is to effect a thorough and convenient closure, while
at the same time preventing air from being compressed into the jar or other vessel
while the stopper is being inserted.
I form the stopper with a projecting part or rim slightly smaller than the neck
or upper inside part of the jar, and I place an elastic ring, say of india rubber,
around this rim so as to form an air tight joint when inserted in the jar. I form a
small hole through the upper part of the jar at such a distance from the top that
the air enclosed in the jar can escape thereby while the stopper is being inserted,
but so as to be covered by the elastic ring when the stopper is fully inserted.
Or I may reverse the construction by fitting the elastic ring on the outside of the
jar and fitting the lid over the same, and forming the lid with a small hole for the
escape of the air..
This lid or stopper may be conveniently removed and put on air tight again as
often as desired.
The accompanying Drawings shew various modifications in illustration of the
manner in which my Invention may be conveniently carried into effect. Figure 1
is a vertical cross section of a stopper and jar made according to one modification,
showing the stopper out of the jar. a is the stopper; b is the india rubber ring
inserted in groove in same, and c is an aperture in jar whereby the air contained in
the jar is allowed to escape while the stopper is being inserted in same. Figure 2
shows the stopper inserted in the jar and there secured; Figure 3 shows the stopper
proper in the form of a cap with ring on the neck (or it might be vice versa) of the
jar, instead of being on the stopper itself. I do not limit myself to the shape or
form of the ring of india rubber, although I prefer the shape to be square or
rectangular as shown; in fact, I have found that in some cases by making the ring
of a double V shape I am able to dispense with the aperture c and still obtain a
similar result, or nearly so.
Figure 4 shows such a stopper inserted in a jar as aforesaid; Figure 5 shows &
cap stopper fitted with india rubber, and similar to the arrangement just described,
wherein the aperture is dispensed with.
Figure 6 shows a portion of one side of the stopper drawn on a larger scale than
the previous Figure, showing the form the ring assumes as it enters the jar and so
allows the air inside the jar to escape between the apex of the diamond shaped ring
and the neck of the jar, but when the stopper is pushed wholly down, the apex of
the ring again expands and a tight joint is produced. The rings may of course be
of a single diamond shape, or as shewn at Figure 7, instead of double, although
I prefer the latter.
*Figures 8, 9, 10, 11, 12, and 13, represent other sections which may suitably be
applied in connection with my improved method of stoppering.
Having now described the nature of my said Invention, and in what manner
the same is to be performed, I declare I am aware that it has been heretofore
proposed to use some forms of rings of india rubber round stoppers for securing
same in jars and other vessels, and in some cases these india rubber rings have
been caused to expand when the stopper has been inserted in the jar or other vessel.
I lay no claim to the application of such rings when taken alone or separately to
the stoppering of jars or other vessels, but I claim as my improvements in stoppering
jars, bottles, and other vessels containing alimentary and other substances,—

page_text: First. The 【employment of india rubber joint ring in combination with an air
aperture and applied to the stoppering of jars or other vessels, substantially in
manner and for the purposes hereinbefore described and illustrated in the accom-
panying Drawings.
Second. The mode and means of stoppering jars and other vessels, substantially
in manner and for the purposes hereinbefore described and illustrated with reference
to Figures 4, 5, and 6, of the accompanying Drawings.
In witness whereof, I, the said William Howard Allen, have hereunto set my
hand and seal, this Twenty seventh day of March, in the year of our
Lord One thousand eight hundred and eighty,
Witness,
