Improvements in or connected with Tins for Enclosing Preserved
Provisions or Foods and the like.
I, ARCHIBALD WHITE MACONOCHIE, of the Firm of Maconochie Brothers, of
131, Leadenhall Street, in the City of London, Merchants, do hereby declare
the nature of my invention to be as follows:-
My invention has for its object to provide tins for containing preserved pro-
visions, or foods, and the like, which tins are expeditiously and economically
made without the use of the solder, or with the use of but a minimum amount
of solder, and which are absolutely tightly closed. According to my invention
the body part of the tin is made from a sheet of tin plate of a size in accordance
with the tin to be produced. The corners are removed and the meeting edges
are turned over in reverse dirctions, so that they can be engaged together by.
folding over each other, or after the manner of hooks. Pressure is then applied
to the edges thus engaged together so as to make a tight joint, which can, if
desired, be further secured by applying solder along the exterior. The upper
and lower ends are then turned out so as to form Hanges at top and bottom
the removal of the corners, as aforesaid, having prevented the formation of the
several thicknesses of metal at the parts to be flanged which would occur if the
corners were not removed. To make the two ends, I take tin plate, and I apply
to it, by means of gelatine, or other suitable cementing material, a sheet, or
sheets, of paper linen, or the like. I then subject the combined plate of tin
and paper, linen, or the like, to the action of dies, so as to stamp therefrom
the two ends, each of which has a depressed mid-portion, the periphery of
which is inclined, so that its lower part will enter the opening at the end of
the body-part of the tin, its upper part being slightly larger in diameter than
the said opening. Projecting around from the upper part of the said inclined
periphery is a flange of a diameter exceeding that of the flanges on the body-
part. The paper, linen, or the like, is situated at the underside of the
end. One of the ends is put in place at one end of the body
part and is forced downwards so that the inclined periphery is forced into
the mouth of the tin, and, owing to its inclination, and its slightly larger.

Improvements in or connected with Tins for Enclosing Preserved
Provisions or Foods and the like.
I, ARCHIBALD WHITE MACONOCHIE, of the Firm of Maconochie Brothers, of
131, Leadenhall Street, in the City of London, England, Merchants, 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 has for its object to provide tins for containing preserved pro-
visions or foods, and the like, which tins are expeditiously and economically
made without the use of solder, or with the use of but a minimum amount of
solder, and which are absolutely tightly closed. I will describe my invention
with reference to the accompanying drawings. Figure 1 shews a part of a plate
for the body of the tin. Figure 2 shews the complete tin bent into shape.
Figures 3 to 6 are sections of tins in various stages of securing the top (the
bottom being secured in like manner). Figure 7 is an enlarged section of
part of a tin to shew more clearly the way in which the joint is formed.
Figure 8 is a plan and Figure 9 is a section of part of a tin plate with paper
linen or the like applied thereto as hereinafter described ready for the formation
of a lid end or cover therefrom and Figure 10 shews a lid end or cover stamped
from a plate so prepared.
According to my invention the body part of a tin is made from a sheet A of
tin plate of a size in accordance with the tin to be produced. The four corners
are removed as shewn at a and the meeting edges are turned over in reverse
directions, as shewn at a², so that they can be engaged together by folding over
each other, or after the manner of hooks. Pressure is then applied to the edges
thus engaged together so as to make a tiglit joint, which can, if desired, be
further secured by applying solder along the joint. The upper and lower ends
are then turned out so as to form flanges a³ at top and bottom, the removal
of the corners, as aforesaid, and as shewn at a, having prevented the formation
of the several thicknesses of metal at the parts to be flanged which would occur
if the corners were not removed. To make the ends, lids or covers of tins I
take tin plate, and I apply to it, by means of gelatine, or other suitable cementing
material, a sheet, or sheets, of paper, linen or the like material of a pure veget-
able character in the nature of cellulose which should be without. lead, clay,
or other impurity, likely to injure the contents of the tin. In Figures 8 and 9
I have shewn a plate so prepared, the paper, linen, or the like 63 being partly
turned up from the tin plate 6 in Figure 8. I then subject the combined plate

page_text: of tin and paper, linen, or the like, to the action of dies, so as to stamp there-
from the end, lid or cover B as shewn in Figure 10 it having preferably a
depressed mid-portion b, the periphery of which is preferably somewhat inclined,
so that its lower part will enter the opening at the end of the body-part of the
tin, its upper part being slightly larger in diameter than the said opening.
Projecting around from the upper part of the said periphery is a flange 62 of
a diameter exceeding that of the flanges a³ on the body-part. The paper, linen,
or the like, is situated at, and covers, the underside of the end, as shewn at 63.
This protects the contents from the tin of the cover, lid or end. In applying
ends or covers, thus made, to a body part as hereinbefore described one of the
said ends or covers is put in place at one end of the body part, as shewn in
Figure 3, and is forced downwards, so that the periphery is forced into the
mouth of the tin, as shewn in Figure 4, and, if it be inclined, owing to its
inclination, and its slightly larger diameter at its upper part, it forms a very
tight closure. The flange on the said end or cover is then spun," or turned,
under the flange of the body part, as shewn at Figure 5, or the flanges are
rolled together, as shewn in Figures 6 and 7, the paper, linen, or the like, being
confined thereby between the parts and making a perfect joint between the
body part and the said end or cover. After the food, or other material, has been
put in the tin the other end or cover is similarly applied and secured, and the
tin as a whole is perfectly closed.
In place of entirely covering the tin plate to form the ends, lids, or covers,
with paper, linen, or the like, a ring of paper, linen, or the like, may be used
sufficient to be enclosed between the flanges.
If desired solder may be applied at the parts where the joint of the body
part meets the joints at top and bottom.
The body part will usually be made circular and the top and bottom in the
form of discs, but I do not limit myself to this particular shape, for example,
the body part may be made oval and a lid or cover made from combined tin
plate and paper, linen, or the like, can be applied to a body part of other con-
struction than that shewn, for example, to a body part stamped with the bottom,
sides and flange all in one piece as indicated by the dotted line, Figure 6.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A tin for enclosing preserved provisions or foods or the like having a
body part which is made by removing the corners from a plate and bending
the edges which are to meet and engaging these bent edges together and
pressing them substantially as hereinbefore described.
2. A cover, lid, or end, for tins for enclosing preserved provisions or foods
or the like, the said cover, lid, or end, being made from tin plate to which is
cemented paper, linen, or the like, as aforesaid so that the said paper, linen,
or the like, covers the part where the joint is to be made substantially as herein-
before described.
3. A cover, lid, or end, for tins for enclosing preserved provisions or foods
or the like, the said cover, lid, or end, being made from tin plate to which is
cemented paper, linen, or the like, as aforesaid, so that the said paper, linen,
or the like, covers the internal surfaces of the cover, lid, or end, and also the
flanges at the part where the joint is to be formed substantially as herein before
described.

4. A tin for enclosing preserved provisions, or foods, or the like, having
body part which is made by removing the corners from a plate and bending
the edges which are to meet and engaging these bent edges together and
pressing them, and having ends made from tin plate to which is cemented
paper, linen, or the like, as aforesaid, so that the said paper, linen, or the like,
covers the internal surfaces of the ends and also extends between the flanges at
