Improvements in and relating to the Manufacture of Loaf-tins,
Drippers, or like Utensils.
We, WILLIAM MORRIS and LUTHER WILKINSON of Manchester Road,
Burnley, in the County of Lancaster, Hardware Dealers and Tin Plate Workers,
do hereby declare the nature of this invention to be as follows:-
Our invention relates more particularly to seamless loaf-tins, drippers, or the
like, and is designed to secure, without rivets, the sole, false-bottom, or metal
plate, by which this class of tin is usually shod, instead of rivetting the same to
the tin.
Our method of making the seamless loaf-tin consists in stamping a sheet metal
plate in such a manner, that under the first stamping process, the loaf-tin or the
like is blocked to shape, leaving however a wing or fold at each corner of the
partially formed loaf-tin, and a flange all round the top sides to form the rim,
which is afterwards wired. In the second process, the wings or folds are doubled
or folded over the ends of the loaf tin or the like, two folds or wings from the
respective corners being folded over each end.
Now, our invention consists essentially in forming the sole, false-bottom or metal
plate (by which a loaf-tin or the like is usually shod) with its two ends bent at right
angles, so that when the sole, false bottom, or the like is put in its place, its bent
ends will overlap each end of the partially formed loaf-tin or the like.
The bent ends of the sole, false bottom, or metal plate are of such depth, that
during the second process of stamping, the two wings or folds at the respective
ends of the seamless loaf-tin will be doubled over, or be brought against the
projecting ends of the sole, or false bottom, overlapping the same, and holding it
very firmly and securely at each corner in position, without rivets or other means
of fastening, when the rim of the tin has been finally wired, which process
effectually secures the folds or wings at each end. Instead of being lapped over
the ends of the loaf-tin or the like, the wings or folds may be bent over the sides
of the tin, and secure the faise bottom, or shod in its place by these means, in an
exactly similar manner to that previously described. Again, in substitution of the
shod, two plates may be secured at each end or side as described, and their free
ends then bent round to form a false seam.
In a modification, which is also applicable to loaf-tins or the like other than
seamless, the bent ends of the false bottom as above described are continued to the
top of the tin, and are lapped over the wire which is used to stiffen the rim, thus
dispensing with rivets.

Improvements in and relating to the Manufacture of Loaf-tins,
Drippers, or like Utensils.
We, WILLIAM MORRIS and LUTHER WILKINSON of Manchester Road,
Burnley, in the County of Lancaster, Hardware Dealers and Tin Plate Workers,
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 :-
Our invention relates more particularly to seamless loaf-tins, drippers, or the
like and is designed to secure, without rivets the sole, false bottom, or metal
plate by which this class of tin is usually shod, instead of rivetting the same to
the tin.
Our method of making the seamless loaf-tin consists in stamping a sheet metal
plate in such a manner, that under the first stamping process, the loaf tin or the
like is blocked to shape leaving however a wing or fold at each corner of the
partially formed loaf-tin, and a flange all round the top side to form the rim, which
is afterwards wired. In the second process the wings or folds are doubled or
folded over the ends of the loaf-tin or the like, two folds or wings from the
respective corners being folded over each end.
Now our invention consists essentially in forming the sole, false bottom or metal
plate (by which a loaf-tin or the like is usually shod) with its two ends bent at
right angles, so that when the sole, false bottom or the like is put in its place, its
bent ends will overlap each end of the partially formed loaf-tin or the like.
The bent ends of the sole, false bottom, or metal plate are of such depth that
during the second process of stamping the two wings or folds at the respective
ends of the seamless loaf-tin will be doubled over or be brought against the
projecting ends of the sole or false bottom, overlapping the same and holding it
very firmly and securely at each corner in position, without rivets or other means
of fastening, when the rim of the tin has been finally wired which process
effectually secures the folds or wings at each end. Instead of being lapped over
the ends of the loaf tin or the like, the wings or folds may be bent over the sides
of the tin, and secure the false bottom, or shod in its place by these means, in an
exactly similar manner to that previously described. Again in substitution of the
shod, two plates may be secured at each end or side as described, and their free
ends then bent round to form a false seam.
In a modification, which is also applicable to loaf-tins or the like other than
seamless, the bent ends of the false bottom as above described are continued to
the top of the tin, and are lapped over the wire, which is used to stiffen the rim,
thus dispensing with rivets.
In the accompanying drawings, Fig. 1 is a plan view of a loaf-tin formed or
blocked to shape under the first stamping process in accordance with our invention.
In this stage, the piece of sheet tin or metal A is blocked into the shape of a
loaf-tin, so as to leave a wing or fold B at each corner of the partially formed
loaf-tin and the flanges C for the formation of the rim all round the top edges
thereof.
Fig. 2 represents the loaf-tin as constructed under the second stamping process.
The metal shoe, sole or false bottom (by which the loaf tin or the like is usually
shod) has its two ends D bent at right angles during the stamping process. The
end wings B are simultaneously and by the same means bent so as to overlap the
said metal shoe or false bottom D, and firmly hold the same in position. It will
be observed that the wings B are at each end of the loaf-tin, dripper or the like,
and that the flanges C are bent ready for wiring to form the rim.

page_text: The loaf-tin, dripper or the like, when finally wired, is shewn in plan view
Fig. 3 where the wire E is slightly exposed at the corners.
The bent ends D of the sole or false bottom may be continued to the top of the
tio, and doubled over the wire forming the rim. In this form the arrangement is
more particularly applicable to drippers and may be adapted to the same without
either wings or rivets. Or, the ends of the sole or false bottom may be fixed at
the sides of the tin instead of at the ends, the wings being bent to overlap the
sides for this purpose. In this case the sole or false bottom is formed with right
angled projectious at the sides or lengthwise, instead of end wise. In another
method, the sole may be constructed in two pieces secured at the ends or sides by
wings or flaps B, but doubled over one another at their free ends to form a false
seam.
We wish it to be understood that we do not claim any right to the particular
formation of the wings B only so far as they overlap and thereby secure the ends D
of the sole or false bottom.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. The manufacture and use of loaf-tins, drippers, and like utensils by stamping
and shodding them, substantially in the manner described and illustrated.
2. The manufacture and use of seamless loaf tins and the like by constructing
them with wings B to overlap the sole or false bottom, and constructing or forming
the said sole or false bottom with its ends D projecting at right angles to facilitate
the overlapping and securing process, substantially in the manner described and
illustrated.
3. The continuation of the bent ends D of the sole or false bottom to the top of
the rim and to be doubled over the same, substantially as described.
Dated this 21st day of November 1896.
