I ARCHIBALD WHITE MACONOCHIE of the Firm of Maconochic Brothers of
Lowestoft in the County of Suffolk Preserved Provision Manufacturers and 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:
This Invention has for its object to effect a considerable economy in the time labor
and cost of manufacture of tin and other metal cans, canisters, boxes, cases and other
similar articles hereafter referred to under the general expression "the tin."
This I effect by making the tin in two parts and uniting such parts by a single
soldered seam.
In order to do this I stamp or strike out two pieces of tin or other suitable metal of
any convenient shape and size, one whereof(hereafter termed "the bottom,")-forms
the body and the other-(hereafter termed "the top ")-the lid of the tin. I then block,
bend, or otherwise shape the bottom to the required form and make a narrow flange
of any suitable width around its upper edge. I then stamp or block the top so as to
form a rim around the outer edge and likewise a groove just inside such rim which
fits over the before mentioned flange I then fit the two pieces together and mechanically
clip and clinch the rim and flange together and turn the edge of the top rim under the
bottom flange and flatten it thereon thus closing the tin.
I then solder the seam or join made by thus uniting the edges when the tin is
hermetically closed and fastened and complete.

page_text: Fig. 3, is a view in section of the tin shewing the top and bottom fitted together
and Fig. 4, is a similar view of the tin complete after the top and bottom have been
clinched and soldered together-a is the top with rim b and groove c-d, is the bottom
with flange e, formed round its upper edge.
Hitherto the bottoms and lids of metal cans, canisters, boxes, cases and other similar
articles have had to be fitted to the body by skilled labor and have required several
solderings instead of one only as by my invention.
Many important advantages are attendant upon my invention which is both
extremely simple and highly effective vizt.
Firstly It greatly reduces the labor and cost of production.
Secondly It obviates the necessity of employing skilled labor.
Thirdly Ii effects a considerable economy in the quantity of solder used.
Fourthly It combines perfect security with great neatness of finish.
Fifthly My invention renders it perfectly impossible for any solder or salts to come
in contact with the contents of the tin.
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. As a new article of manufacture a tin or other metal can, canister, 'case, box or
other similar article made in two parts which together constitute the entire tin and
which are stamped out, shaped fitted, closed, and fastened together by a single soldered
scam all substantially in the manner and for the purposes hereinbefore described and
shewn.
2. In a tin or other metal can, canister, case, box or other similar article uniting the
top and bottom portions thereof by a single soldered scam or join placed centrally or
otherwise, and otherwise made and fitted, all substantially in the manner and for the
purposes herein before described and shewn.
