PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Metal Canisters, Boxes, or
other like receptacles.
I, BENJAMIN SCOTT of James Street in the City of Carlisle, Lithographer, and
Tin Box Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to the manufacture of metal canisters, boxes and
other like receptacles, and its object is to fit an air-tight inner rim to the mouth of
the body of the receptacle without soldering or tacking as is usual in such
manufacture; also to fit an inner lid permanently to the inner rim and inde-
pendently of the body and outer lid of the receptacle.
For the purpose of the invention the upper edge of the body of the receptacle
is first formed with an inturned flange or lip and this flange or lip is then depressed
or sunk in the middle so as to form a groove or U-shaped recess all round to
receive the outer flange or edge of the inner rim. The inner rim before its flange
is inserted into the said groove or recess has two down-turned flanges at the outer
and inner edges respectively and the inner flange forms a seat for the inner lid of
the box which is hinged or secured to the inner rim before this is fixed to the box
body.
In order to fix the inner rim to the box body the outer flange of the rim is let
into the groove or recess in the box body and then this outer flange and the flange
of the box body are coiled or curled around each other whereby these parts
become firmly united or locked without the use of solder or tacking, the top of the
inner rim becoming at the same time sunk below the top edge of the box and a sort
of beading being formed all round.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Metal Canisters, Boxes, or
other like receptacles.
I, BENJAMIN SCOTT of James Street in the City of Carlisle, Lithographer, and
Tin Box Manufacturer, 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 reference to the manufacture of metal canisters, boxes and
other like receptacles, and its object is to fit an air-tight inner rim to the mouth of
the body of the receptacle without soldering or tacking as is usual in such
inanufacture; also to fit an inner lid permanently or otherwise to the inner rim and
independently of the body and outer lid of the receptacle.
For the purpose of the invention the upper edge of the body of the receptacle is
first formed with an inturned flange or lip and this flange or lip is then depressed
or sunk in the middle so as to form a groove or U-shaped recess all round to
receive the outer flange or edge of the inner rim. The inner rim before its flange
is inserted into the said groove or recess has two down-turned flanges at the outer
and inner edges respectively, and the inner flange forms a seat for the inner lid of
the box which can either be hinged or secured to the inner rim before this is
fixed to the box body, or be loose.

page_text: In order to fix the inner rim to the box body the outer flange of the rim is let
into the groove or recess in the box body and then this outer flange and the flange
of the box body are coiled or curled round each other whereby these parts become
firmly united or locked without the use of solder. or tacking, the top of the inner
rim becoming at the same time sunk below the top edge of the box, and a sort of
beading being formed all round.
The accompanying drawings will serve to illustrate my invention,
Figure 1 is a vertical section of the upper portion of the body a of the
receptacle as first formed with an inner flange or lip b.
Figure 2 is a similar view showing this flange or lip depressed or sunk in the
middle so as to form a groove or U-shaped recesse all round to receive the outer
flange or edge of the inuer rim.
Figure 3 is a vertical section of the inner rim of before its insertion into the
groove c of the box body; it will be seen that the said inner rim has two down-
turned flanges, riz.-one e at the outer edge, and one at the inner edge. gg are
gudgeons or hollow projections to receive the pintles or pivots of the inner lid.
Figure is a vertical section taken at right angles to Figure 3 showing the
inner rim d with the inner lid h hinged thereto. is a finger piece for use in
opening this lid.
Figure 5 is a vertical section showing the inner rim d fixed to the box body a.
To effect this the outer flange e of the inner rim is let into the groove c in the box
body, and then this flange e and the flange of the box body are coiled or curled
round each other as shown so that these parts become firmly united or locked
without the use of solder or tacking, the top of the inner rim d becoming at the same
time sunk below the top edge of the box. " is the outer lid which can be attached
to the box body in any suitable manner.
Figure 6 is a fractional view on a larger scale showing the union between the
flange of the inner rim and that of the box body.
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. The mode or method substantially as hereinbefore described of fitting an
inner rim to the mouth of the body of a metal canister, box or other like
receptacle.
2. A metal canister, box or other like receptacle made substantially as herein-
before described and represented in the accompanying drawings.
