DAN RYLANDS of Shepcote Stairfoot near Barnsley in the County of York
Glass Bottle Manufacturer do hereby declare the nature of this invention to be
as follows
--
My present invention has for its object the manufacture of glass or other ware
or bottles in such a way that glass only will come in contact with the contents of
the bottle and that the contents of the bottle can be boiled or cooked with the
stopper screwed down and also that the screw cap holding the glass stopper down
can be easily cut so as to set the glass cap at liberty. In carrying out my
invention I manufacture a bottle in a machine which machine not only forms a
screw thread on the outside of the bottle mouth but also forms in such screw
thread one or more vertical slots which slots come a little way below such screw
thread. I also form by this machine on the top side of mouth of bottle an annular
groove for receiving the india rubber washer which is fixed on the outside of the
bottle mouth. I then make or form a glass cap which glass cap is so shaped that
it will pass over the raised portion of the mouth of the jar or bottle and will
impinge upon the india rubber washer. I then make a screw ferrule of tin or
other suitable substance which will work on the screw thread formed on the glass
cap the rim of which screw ferrule will impinge around the outer edge of such
glass cap bringing such cap down into an air-tight position. Near the centre
of this glass cap I form a small hole such hole being wider on the outside of
the cap than it is on the inside of the cap. As this hole is pierced right through
the cap it allows of steam passing through from the substances being cooked or
boiled inside the jar and when such substances are sufficiently cooked a small piece
of sealing wax or cement or other suitable substance is dropped in the hole and
the size of the hole being so much smaller at the lower side of the cap than it is
on the upper side of the cap this sealing or cement wax is stopped running through
into the jar and thus effectually stops the hole. After screwing the tin ferrule as
tightly down as it is to be screwed it is difficult to open the jar by unscrewing
such ferrule and a much handier way of opening the jar is by introducing into
the vertical slot before described a small sardine knife or other such instrument
and passing this knife up the said slot the tin ferrule is at once cut open and the
glass cap set at liberty.

1, DAN RYLANDS of Shepcote Stairfoot near Barnsley in the County of York
Glass Bottle Manufacturer 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 :-
My present invention has for its object the manufacture of glass or other ware
or bottles in such a way that glass only will come in contact with the contents
of the bottle and also that the contents of the bottle can be boiled or cooked with

page_text: the stopper screwed down and further that the screw cap holding the glass stopper
down can be easily cut so as to set the glass cap at liberty.
In carrying out my invention I manufacture a bottle in a machine which
machine not only forms a screw thread on the outside of the bottle mouth but
also forms in such screw thread one or more vertical slots which slots come a little
way below such screw thread.
I also form by this machine on the top side of mouth of bottle an annular
groove for receiving the india rubber washer which is fixed on the outside of
the bottle mouth. I then make or form a glass cap which glass cap is so shaped
that it will pass over the raised portion of the mouth of the jar or bottle and will
impinge upon the india rubber washer. I then make a screw ferrule of tin or
other suitable substance which will work on the screw thread formed on the glass
cap the rim of which screw ferrule will impinge around the outer edge of such
glass cap bringing such cap down into an air tight position. When it is desired
to cook or boil the contents in the jar or bottle I form near the centre of the
glass cap a small hole such hole being wider on the outside of the cap than it is on
the inside of the cap.
As this hole is pierced right through the cap it allows of steam passing through
from the substances being cooked or boiled inside the jar and when such substances
are sufficiently cooked a small piece of sealing wax or cement or other suitable
substance is dropped in the hole and the size of the hole being so much smaller at
the lower side of the cap than it is on the upper side of the cap this sealing wax
or cement is stopped running through into the jar and thus effectually stops the
.hole. When it is not required to boil the contents in the bottle or jar with the
glass cap on, the perforated hole in the cap is not necessary; and for this and
other purposes I make the glass cap without the hole.
After screwing the tin ferrule as tightly down as it is to be screwed it is difficult
to open the jar by unscrewing such ferrule and a much handier way of opening the
jar is by introducing into the vertical slot before described a small sardine knife or
other such instrument and by passing this knife up the said slot the tin ferrule is
at once cut open and the glass cap set at liberty.
In order that my invention may be more clearly understood I attach drawings,
of which,
Fig. 1 is a sectional elevation, Fig. 2 an elevation, and Fig. 3 a plan view of
a jar capable of being hermetically sealed in accordance with my invention.
In Figs. 1 2 and 3, a is a jar preferably made by machine formed at the outside
of the mouth portion with a screw thread 6 having interruptions or vertical slots
at cc; d an annular seating formed for the reception of the elastic jointing ring ef
the glass cap perforated at g, and the screw ferrule of tin or other suitable
material having its upper portion machined into an internal flange as shown at i.
The method of hermetically sealing and protecting the contents of a jar is as
follows-The jar being filled and the glass cap fjointing ring e screwed ferrule h
being in position as shown by Fig. 1, the body of the jar is placed and suspended
in a steam or water cooking-bath, the enlarged diameter of the screwed mouth
portion b resting on the cover of the bath in such a manner that the steam is
confined within the bath. After the contents have been sufficiently cooked the
perforation 9 is closed by sealing wax or other suitable substance.
To open the jar a sardine knife or other suitably-formed sharp instrument is
placed in one of the slots cc and the screwed ferrule cut open, when the glass cap
an be removed. Although I have not shown in the drawings a glass cap without
hole, it will be well understood that in some cases it may be preferable to make
the glass cap without the hole or perforation g.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is―
1. The combination of the glass cap perforated at y with the screw ferrule h

page_text: and jointing ring e secured to the glass bottle or other vessel in the manner and for
the purpose herein described.
2. The screw ferrule h, jointing ring e, and slots c c, in combination with either
a perforated glass cap for a solid glass cap so adapted to the mouth of the bottle
or jar as to prevent the contents coming in contact with either the screw ferrule or
the jointing ring.
3. The formation of slots cc on the outside of bottle or jar mouths as and for
the purpose herein described.
4. A glass cap perforated for the egress of steam in such manner as to allow of
the perforation being subsequently rendered airtight by sealing wax or other
suitable substance or substances.
