PROVISIONAL SPECIFICATION.
An Improved Method of Making Cans, Hollow-ware, and the like.
JOHN BANBURY Merchant City of Auckland Colony of New Zealand do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to fasten the heads of can to body by means of
einbedding a.wire between the edges of body and flanged head by crimping, so that
alf the section of wire lies in a groove on the head and the other half of section
in a groove on the body, thus keying it firmly on, after embedding the wire
entirely round the can the finishing end of wire is led out at the edge, the tin
being crimped around it-this projecting end of wire by being drawn out, forms a
ready means of opening the can..
To render the cans additionally airtight the edges may be dipped in any of the
various sealing solutions or solder.

An Improved Method of Making Cans, Hollow-ware, and the like.
I JOHN BANBURY Machinery Agent at present residing at Burford Oxfordshire
England formerly of the City of Auckland Colony of New Zealand 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 :-
The methods heretofore adopted in making cans etc. have been either by soldering
or double seaming the lids to the bodies of same. .
The object of this invention is to secure the heads of cans etc. to their bodies, by
the mechanical device of keying or locking the same together by embedding a
wire or metallic strip between the can body and the lid or head of same, by
crimping, forcibly embedding, or other method, by which a portion of the section
of wire or metal strip is forced into, and lies embedded in a groove in the can-body,
the other portion of the section of the wire lies in a groove in the flange of the
lid, or the whole may be embedded in either the can-end or the flange of the lid
simply engaging with the parts immediately opposite it, thus keying or locking
the lid and body firmly together, and greatly increasing the strength and solidity
of same.
After embedding the wire around the can or other article, the end of the wire is
led out at the side or end of the can, the metal being crimped firmly round it-the
wire thus embedded forms a locking or keying medium, which on being withdrawn,
admits of the lid being easily removed.
Should it be necessary to render the joint additionally air-tight, the same may
be treated by any of the various sealing solutions, or solder.
Having in the above description explained the nature of my invention and how
the same is performed, I do not restrict myself exclusively to the descriptions
therein given, as many modifications may be introduced without, departing from

page_text: the principle of the method described, as for instance rigs. 4,
accompanying drawings.
8 and in the
Figure 1. is a plan view of a can having its top and end closed in accordance
with my invention.
Figure 2. is a vertical section through body of can, taken practically on the
line 2-2 of Fig. 1.
Figure 3. is a section through lid and cover illustrating the joint shewn in Fig. 2,
but enlarged.
Figure 10. illustrates a key which may be used in the unsealing or opening
cans &c., made as above.
In the accompanying drawings the body A, is shewn cylindrical altho any desired
contour may be given it, such as square, oval, octagonal etc., and the bottom may
be attached internally or externally as shewn in the accompanying drawings.
The lid or cover B is provided with an upturned marginal flange b. and the
wire C. employed in effecting the sealing, fastening, or keying is located between
the flange of the lid, and the contiguous surface of the body.
In order to accomodate the wire in the manner set forth, and also that the flange
of the cover may closely engage with the body of the can, an annular chamber Ď.
is formed between the flange of the cover and the body, and the said chamber may
be produced in various ways, as illustrated in the drawings.
Reference is to be had to the accompanying drawings forming part of this
Specification, in which similar letters of reference indicate corresponding parts in
all the views.
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
The peculiar method or system of making or closing cans etc., which consists in
placing a wire or metal strip between the can body and the lid or cover substantially
as before described in this Specification, and illustrated in the accompanying
drawings.
Dated this First day of December 1894.
