Improvements in the Manufacture of Jars or Vessels for Preserving
Alimentary and other Substances.
I, ALEXANDER LEWIS, of 43, Moffatt Road, Palmer's Green, in the County of
Middlesex, Commercial Traveller, do hereby declare the nature of this invention
to be as follows:-
My invention relates to jars or vessels for preserving alimentary and other
substances the object of my invention being to provide a vessel which combines the
advantages of a glass, earthenware or like vessel with the advantages of a metal
vessel as regards the closing and sealing.
A vessel constructed according to my invention has the body made of glass,
earthenware or other suitable material and a metal rim, ring or flange incorporated
with or embedded in such material around the mouth of the vessel whilst the latter
is in a plastic condition the said rim, ring or flange projecting to such an extent
that a lid or cover may be attached to it hermetically by soldering or otherwise.
In order to form a good bond between the metal and the glass, earthenware or
the like holes may be formed in the rim, ring or flange in which the material con-
stituting the body of the vessel will be pressed and unite; or flanges or projections
may be provided.
I sometimes construct the vessel with an additional cover which will serve for
temporarily closing the vessel after the hermetically closed cover has been removed.

Improvements in the Manufacture of Jars or Vessels for Preserving
Alimentary and other Substances.
I,..ALEXANDER LEWIS, of 43, Moffatt Road, Palmer's Green, in the County of
Middlesex, Commercial Traveller, 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 invention relates to jars or vessels for preserving alimentary and other
substances the object of my invention being to provide a vessel which combines the
advantages of a glass, earthenware or like vessel with the advantages of a metal
vessel as regards the closing and sealing.

page_text: A vessel constructed according to my invention has the body made of glass,
earthenware or other suitable material and a metal rim, ring or flange incorporated
with or embedded in such material around the mouth of the vessel whilst the latter
is in a plastic condition, the said rim, ring or flange projecting to such an extent
that a lid or cover may be attached to it by soldering or otherwise, to hermetically
seal the contents of the vessel.
In order to form a good bond between the metal and the glass, earthenware or
the like holes may be formed in the rim, ring or flange through which the material
constituting the body of the vessel will be pressed and unite; or flanges or pro-
jections may be provided.
I sometimes construct the vessel with an additional cover which will serve for
temporarily closing the vessel after the hermetically closed cover has been
removed, and in order to isolate the contents of the vessel from the metal top I
sometimes place over the substance contained in the said vessel a disc or sheet of
glass or other suitable material.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which:-
Figure 1 is a sectional view of my improved vessel; and,
Figure 2 is a similar view of the same filled and hermetically closed:
1
Figure 3 is a sectional view of a suitable form of mould for manufacturing glass 2
jars or vessels according to my invention, the parts being in the position they
occupy after having moulded a vessel and being drawn to a smaller scale than
Figures 1 and 2.
Figure 4 is an elevation of the metal rim or ring which I embed in the material
of which the vessel is composed; and,
Figure 5 is a view drawn to the same scale as Figure 3 of the upper die of the
mould.
2
Figures 6 and 7 are sectional views illustrating a slight modification.
Similar letters of reference indicate corresponding parts in the several figures.
a is the body of the vessel and b is the metal rim embedded in the same.
The 3
said rim as shewn is of circular shape but it will be obvious that it may be made of
any other desirable shape to suit the shape of the vessels to be produced.
The apparatus shewn in the drawing for manufacturing the vessel shewn in
Figures 1 and 2 comprises a base plate c, a ring d which fits on to a projecting
portion e on the said base plate, a top f which fits on to the said ring and a plunger g 3
which fits in and is capable of sliding through a hole in the said top. The latter
is hinged at h to the base plate c and a catch i is provided for holding the parts of
the mould together.
The ring b to be embedded in the material of which the body a of the vessel is
formed and which is shewn detached in Figure 4 is fitted on to the plunger so 4
that the lower part projects as shewn in Figure 3 a recess j being formed around
the plunger to receive the upper part as shewn in Figure 5.
In moulding a vessel, the plunger being raised out of the lower part of the
mould the quantity of molten glass or other material required for making the
vessel is placed in the mould whereupon the plunger is depressed to the position 4
shewn in Figure 3 whereby the plastic material in the mould is forced up to fill
the latter and around the lower part of the ring b and through the holes k formed
in the ring, so that the said ring b is incorporated with or embedded in the
glass, a good bond between the metal and the glass being formed by the
glass passing through the said holes k.
It will be obvious that instead of providing the ring with holes as above described
it may be provided with flanges or projections for securing a good bond, and in
some cases it may be left quite plain.

The die g being raised the completed vessel can be removed from the mould the
metal ring b will project above the edge of the same and serve for the attachment 5
of a cover in the usual manner,

page_text: m represents the disc or piece of glass or other suitable substance which can be
placed, so as to rest on the top of the body of the vessel inside the ring, in order to
entirely isolate the contents of the vessel from the tin top.
I sometimes modify the construction herein before described by arranging that
the ring 6 shall practically have the glass in contact with it on one side only. In
this modification which is shewn in Figures 6 and 7 the mould is provided with
a rib n which limits the upward movement of the glass in the mould around the
outside of the ring b under the pressure of the plunger. The space above this
rib serves to allow the ring b when heated from the inside by the contact of the
molten glass to bulge outwards under the pressure. It will thus be seen that a
rib o upon the vessel is in engagement with a groove upon the ring thereby afford-
ing a good bond between the two.
With this modification it is necessary in order that the vessel can be removed
from the mould that the ring portion d of the latter should be jointed so that it
can be opened.
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. A jar or vessel for preserving alimentary and other substances having the
body of the vessel made of glass, earthenware or other suitable material with a
metal rim, ring or flange incorporated with or embedded in the material around
the mouth of the vessel, the said rim, ring or flange serving to receive a lid or cover,
substantially as, and for the purposes, set forth.
a
2. In a jar or vessel of the kind described in Claim 1, a rim or ring such as b
provided with holes or their equivalents for forming good bond between the
metal ring and the glass, earthenware or the like from which the body of the vessel
is formed, substantially as set forth.
3. A jar or vessel for preserving alimentary or other substances having a body of
glass, earthenware or other suitable material a rim or ring embedded in the
material forming the mouth of the vessel and a lid or cover secured to the said rim
or ring, substantially as described.
4. The combination with a jar or vessel for preserving alimentary or other sub-
stances having a body of glass, earthenware or other suitable material, and a rim
or ring of metal embedded in the material for the attachment of a metal lid or
cover, of an additional cover for isolating the contents of the vessel from the lid,
substantially as described.
5. The manufacture and use of vessels for preserving alimentary and other sub-
stances, substantially as hereinbefore described and illustrated in the accompanying
drawings.
