PROVISIONAL SPECIFICATION.
An Improved Method of Making the Joints of Tin and Iron Ware
in the Manufacture of Stoves and analogous Articles.
We, JOHN WILLIAM BERNARD WRIGHT, of 390 New John Street West,
Birmingham, in the County of Warwick, Lamp Manufacturer, and WILLIAM
RANDLE, of 407 Bearwood Road, Smethwick, in the County of Stafford, do hereby
declare the nature of our said invention to be as follows:-
Our invention relates to an improved method of making the joints of tin and
iron ware in the manufacture of petroleum stoves and gas stoves for cooking and
heating; for the purpose of strengthening and improving the appearance of such
stoves and analogous articles.
Our invention consists in forming and uniting the plates of sheet metal together
by means of a double wire edge as usually understood in the trade, one, the smaller,
edge being closed, or partly so, the other, the larger, being left partly open and
being sufficiently large to allow of the smaller edge being slipped inside it, thus
forming a close, firm and bold joint. The joints may either be left circular or the
edges may be afterwards flattened, as preferred. And if desired we may form a
square or other shaped joint in the same way our invention being in no way confined
to a round wire edge as above.

COMPLETE SPECIFICATION.
An Improved Method of Making the Joints of Tin and Iron Ware
in the Manufacture of Stoves and analogous Articles.
We, JOHN WILLIAM BERNARD WRIGHT, of 390 New John Street West,
Birmingham, in the County of Warwick, Lamp Manufacturer, and WILLIAM
RANDLE, of 407 Bearwood Road, Smethwick, in the County of Stafford, do hereby
declare the nature of our said invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
Our invention relates to an improved method of making the joints of tin and
iron ware in the manufacture of petroleum stoves and gas stoves for cooking and
heating, trunks, deed boxes and other articles manufactured from sheet metal; for
the purpose of strengthening and improving the appearance of such stoves and
analogous articles.
Our invention consists in forming and uniting the plates of sheet metal together
by means of a double wire edge, as usually understood in the trade; one, the
smaller edge, being closed, or partly so; the other, the larger edge, being left
partly open, and being sufficiently large to allow of the smaller edge of another
plate being slipped inside it, thus forming a close, firm, and bold joint. The joints
may either be left circular, or the edges may be afterwards flattened, as preferred;
and, if desired, we may form a square or other shaped joint in the same way; our
invention being in no way confined to a round wire edge, as above mentioned.
And in order that our said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar figures
of reference indicate corresponding parts.

page_text: Fig. 1 is a transverse section of the plate shown in plan in Fig. 3.
Fig. 2 is a transverse section illustrating the method of uniting two plates
together.
Fig. 4 is a transverse section illustrating square joints.
The larger joints 5 are formed with an opening 6 to allow of the insertion of the
small joint 7 of the adjoining plate.
The joints may be circular, square, elliptical, hexagonal, flattened, or otherwise.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
In the manufacture of petroleum and gas cooking and heating stoves and analogous
articles, the application and use of a "double wire edge" in forming and uniting
plates of sheet metal, substantially as herein before described and illustrated by the
drawings.
