"IMPROVEMENTS IN THE CONSTRUCTION AND MANUFACTURE OF TIN AND OTHER
METAL CANS OR CANISTERS AND BOXES OR CASES
"
The object of my invention is to greatly facilitate the manufacture of tin and
other metal cans or canisters and boxes or cases by a novel method of fitting the
lid whereby a considerable economy in time labour and expense is effected
·
Hitherto the lids of such articles have had to be fitted therein by the aid of
skilled labour owing to the necessity of adapting the shape of the body to the size
of the lid
Now my invention consists Firstly. In turning in the upper edge of such body
all round so as to form a V groove and Secondly In forming a narrow rim or flange
upon the underside of the lid which when placed on the top accurately fits into
such groove and can be readily secured therein by soldering
By this simple and effective construction and arrangement I entirely dispense
with the present troublesome and expensive method of fitting the lid inside the
body of the can or other article
I also where it is desirable fit the bottom of the can or other article in a similar
manner
1
Another advantage of my invention is that it combines perfect security. with
great neatness of finish

IMPROVEMENTS IN THE CONSTRUCTION AND MANUFACTURE OF TIN AND OTHER
METAL CANS OR CANISTERS AND BOXES OR CASES
"
This Invention more particularly relates to tin cans or canisters and boxes or
cases used for holding preserved provisions, but may also be advantageously applied
to other articles of a like nature
Hitherto the rims of such cans or canisters and other similar articles have been
first made separately and then fitted on the body of the can, thus necessitating the
aid of skilled labour, owing to the necessity of adapting the shape of the body of
the can or canister to the size of the rim
Now the object of my invention is to greatly facilitate the manufacture of such
articles by a novel method of forming such rim out of the body of the can, or
canister or case itself, whereby a considerable economy in time labour and expense
is effected and all necessity for skilled labour is entirely dispensed with
And in order that my said invention may be better understood and readily
carried into effect, I will now with the aid of the accompanying drawings (whereon
similar letters of reference indicate corresponding parts;) proceed more particularly
to describe and ascertain the same
Figure 1 of such drawings shews the upper edge a of the body of a tin canister
turned down so as to form a rim and channelled with a groove b as presently
described Figure 2 shews a plan view of the lid c of such canister with its rim or
flange d-Figure 3, shews a cross section of such lid-Figure 4 shews a sectional
elevation of the upper portion of a can or canister made according to my invention
which consists in turning down the upper rim or edge a of the body of the can or
canister all round and then channelling it so as to form a V shaped groove b therein,
'wherein the rim or flange d of the lid c accurately. fits when placed in the top of
the canister and is readily secured by soldering the same therein
I would here observe that I particularly wish to point out that the novel feature
of my present invention consists in turning down the top of the can itself so as to
form such rim, thus dispensing with all necessity for the aid of skilled labour in
order to fit the rim on the body of the can or canister
When desired the bottom of the can or canister may be fitted and secured to the
body thereof in a similar manner.
By this simple and effective method I entirely dispense with the present
troublesome and expensive mode, thus effecting a considerable economy in the cost
of production
Having thus particularly described and ascertained the nature of my said
invention of Improvements in the construction and manufacture of tin and other.
metal cans or canisters and boxes or cases and the manner of carrying the same
into effect I would have it understood that what I claim as novel and of my
invention and desire to secure by the herein before in part recited Letters
Patent is:
Firstly. The turning down the upper rim or edge of the body of a tin can or
canister or case or other similar article and forming a V shaped groove
therein so as to allow of the lid of such canister or other similar -article
being fitted and secured therein in the manner hereinbefore specified and
shewn

page_text: Secondly. The application of my improved method of fitting to the bottom of a
tin can or canister or case or other similar article in the manner herein-
before specified
In witness whereof I the said James Maconochie have hereunto set my hand
and seal this tenth day of January in the Year of Our Lord One thousand eight
hundred and eighty four
