Improvements in the Manufacture of Bread Tins and the like.
I SAMUEL NUTTALL ASHWORTH, Tinplate Worker of 21 Butler Street
Oldham Road, Manchester do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to simplify the manufacture of bread tins and the
like, and at the same time to make them more durable. In carrying out my.
invention I make each tin from one sheet of metal or blank having an angular
piece cut out of each corner. I next fold over, or edge, by means of a suitable
edging machine or tool, the edges that are to form the corner of the bread tin &c.
The tin is then stamped in suitable dies and at the same time the upper edges
are folded over, ready for wiring. After stamping the tin the edges forming the

with a name, trade mark, or other device at the time of stamping it.
The special wiring machine which I propose to use for wiring the edges of tins
is, as before stated, somewhat similar to an angle bending or folding machine but
made with a solid bed-plate. Above this is a bar the ends of which are capable of
rising and falling in vertical grooves formed in standards at the ends of the bed-
plate. The bar is caused to rise and fall by two excentrics or cams keyed upon a
shaft which can be partially turned by means of a lever or handle. The ordinary
guide or "fence" used in the angle bending machine is not required for the purpose
of wiring.

Improvements in the Manufacture of Bread Tins and the like.
1 SAMUEL NUTTALL ASHWORTH, Tinplate Worker of 21 Butler Street
Oldham Road, Manchester, 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 object of my invention is to simplify the manufacture of bread tins and the
like and at the same time to make them more durable.
The nature of my invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the two sheets of drawings hereunto annexed and the following explanation thereof.
In carrying out my invention I make each tin from one sheet or blank of metal
as shown at a Fig. 1 on Sheet 1 of the annexed drawings having an angular piece b
cut out of each corner. I next fold over or edge, by means of a suitable edging
machine or tool, the edges that are to form the corners of the bread or other tin,
as shown by the dotted lines at Fig. 1.
The tin is then stamped in suitable dies which bend up the sides and ends, as
shown at Fig. 2 and at the same time the upper edges at c are folded over ready

page_text: for wiring. After stamping the tin, the edges forming the corners thereof are
locked together and beaten over to make a joint as shown at Fig. 3.
The wire may then be put in by means of a special wiring machine resembling an
angle bending or folding machine (or the tin may be finished in the usual manner)
as shown at Fig. 4; I may impress the tin with a name, trade mark or other device
at the time of stamping it.
The special wiring machine which I propose to use for wiring the edges of the
tins is illustrated in front elevation at Fig. 5 and end view at Fig. 6 on Sheet 2 of
the annexed drawings. It is, as before stated, somewhat similar to an angle
bending or folding machine but made with a solid bed-plate e. Above this is a
bar the ends of which are capable of rising and falling in vertical or slightly
inclined grooves formed in the standards g at the ends of the bed plate.
The bar is pressed downwards by two excentrics or cams h keyed upon a
shaft which can be partially turned by means of a lever or handle k two springs
being provided for lifting the bar f when the handle k is raised again.
The ordinary guide or "fence" used in the angle bending machine is not required
for the purpose of wiring but I prefer to make grooves m in the face of the
bed-plate e to receive the wired edges 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 :-
The improvements in the manufacture of bread tins and the like from a single
sheet or blank substantially as hereinbefore described and illustrated by the
drawings annexed.
