Engineer do hereby declare the nature of this invention to be as follows:-
The chest box or tank is made of sheet metal coated or otherwise, & is designed
for the transporting of tea, coffee, or like goods but if a suitable cement or packing is
used in the joints it can be used to contain liquids. The construction is such that.
the sides & ends being formed the parts can be put together without skilled labour
& form a strong & complete box, the parts can also be packed one within the
other for transport & thus the parts of a number of boxes will occupy very little
space, the box can also be taken apart when desired, or after use.
The box is made of any number of parts, the edges of each side plate are folded
but the edges which join to form the circumference of the sides, lock one within the
other, at the top & bottom the edge is folded outwards & forms a hold for the
connecting clips & also a strengthing edge.
The top & bottom is formed so that the main portion is level or nearly so with
the edges of sides, but immediately on the inside of & all round the sides a valley is
formed, the side of this valley which is nearest the side of the chest is parallel to it or
nearly so, the edge of the top & bottom plate is further extended & carried over
the outside of sides, the one side of valley & this outside edge thus forms a recess
into which the edges of the sides fit tightly, this recess & the joint in sides makes
the chest quite self supporting & firm.
The clips for firmly securing the sides & ends together are of strips of sheet
metal, they are placed under the folded edge at the top & bottom of sides & over
the edge of the top & bottom plates & are doubled into the valley formed in the
top & bottom plate.
A few clips can also be soldered to body of box & the contents thereby sealed.
To make the chest as airtight as possible a packing of hemp or such like material
can be placed in joints of side & in the recess of top & bottom plates.
To add to the strength of box the sides & ends can be corrugated or panelled.

Improved Method of Constructing Metal Chests and Tanks.
I, GEORGE FILEWOOD DEWDNEY of Dumballs Road, Cardiff, Glamorganshire,
Engineer, do hereby declare the nature of the said invention and in what manner
[Prine Ad

page_text: the same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This invention relates to sheet-metal chests, boxes and tanks specially applicable
for containing tea, coffee and other goods and has for its object to construct these
chests or the like of a number of parts capable of being readily fitted together or taken
apart and which parts separated, may be packed one within or close to another so as
to occupy very little space.
The invention will be best understood by reference to the accompanying drawings
in which :-
Figure 1 is a view of one of my improved chests or boxes shown partly in vertical
section and partly in front elevation.
Figure 2 is a horizontal section of Figure 1.
Figure 3 is a horizontal section of one of the separable portions of the vertical walls
of the chest or box shown in Figures 1 and 2.
Figure 4 is a front elevation and
Figure 5 an end elevation of one of the clips shown in Figure 1 for securing the
top and bottom of the chest in position, this clip being represented as in its normal
condition or before it is bent, and
Figure 6 is an end elevation of the same clip after it is bent.
Figures 7 and 8 are perspective views of other forms of clip.
Figures 9 and 10 are sections, showing one manner of packing the joints when it is
desired that they should be fluid-tight; these two Figures being drawn to a scale.
larger than that to which the other Figures are drawn.
Like letters of reference indicate like parts throughout the drawings.
As shown in the drawings the vertical walls a al a and a3 are formed in two
non-soldered parts A A', each part A or A¹ constituting or embodying respectively
two of the walls a a¹ or a as; as an example the part A comprising the walls a a', is
shown in Figure 3, as separated from the other part. The two parts A A¹ if desired
may be similar to each other in all respects so that both of them may be formed by
the same apparatus, and, as will be well understood, a number of them for
transportation or other purposes may be "nested" together so as to occupy a very
small amount of space.
The walls aa are formed with similar folded or hooked vertical edges at and the
walls al a³ are formed with folded edges a capable of engaging with the edges a' as
shown in Figure 2, and the upper and lower edges of the walls aa a³ are folded
over outwards and downwards as at a as shown in Figure 1.
The top B and bottom B¹ which may be alike and interchangeable, are each formed
so that the central or main portion b thereof is level or nearly level with the
surrounding turned-over edge between which and the portion b is formed a channel
or valley 62. The turned-over edges which as it were constitute a continuous
recess are adapted to fit tightly over or on to the folded or hooked turned-down
edges a of the parts A A¹ whereon they may be rigidly secured by clips C. Each of
these clips C is formed with a hook or hooked portion c capable of engaging with one
of the folded edges a", and with projecting portions or tabs el which may be readily
bent over one of the turned-over edges b¹ as shown in Figure 1; Figure 6 represents
the shape of one of the clips C with the tabs c¹ bent as last previously described.
The part of the clip when passed into the space between the body of the box and
the over-hanging flange a" (Figure 9) serves as a wedge to force the latter outward
against the contiguous flange of the cover and so aids in making a tight joint.
Further it acts to protect the box against accidental deformation. Each clip C
have any desired number of tabs c¹; an examples, two different forms of the clip are
represented in the drawings, that shown in Figure 4 having three tabs and that shown
in Figure 7 having only one such tab, or the clip may be a continuous strip slit only
for greater convenience of bending as in Figure 8; any of these connecting strips can be
continued round a corner and be curved for that purpose.
The edges of the parts A A¹ being bent or folded over in the manner previously
described render these parts very rigid, but to increase the rigidity of these parts,

page_text: they may be formed with panels a or corrugations as or as shown in the drawings,
with both panels and corrugations, and some of these corrugations as shown in Figure 1,
may constitute a scale by which the quantity or bulk of the contents of the chest
may be readily ascertained.
The top B and the bottom B' may also be provided with corrugations 8, as shown,
and the top may have small pockets 63 or other devices thereon for receiving an
address card or label.
When the chest, box, or tank is to be used for containing liquid, I may provide
each of the before described joints with a packing D of hemp or other suitable
inaterial; as shown in Figure 9 the packing D is placed in the recessed edge b¹ of
the top or bottom B or B', and, as shown in Figure 10, two strips of packing may be
used, one within the folded edge at and the other within the folded edge a. The
packing employed might be a plastic or cement packing; or such a packing could be
combined with the hemp packing aforesaid. By careful construction and a choice of
proper packing, boxes or vessels according to this invention will not leak even though
charged with such a searching fluid, as, say, petroleum.
If desired one or more of the clips C or the tabs thereof may be soldered to the
body of the chest and the solder sealed so as to secure the contents of the chest
against opening by any unauthorized person. The chest, box, or tank instead of being
rectangular as shown in the drawings may be of other desired shape for example, it
may be cylindrical, and instead of the body being formed in two parts any other
desired number may be employed.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. In a sheet-metal chest tank or the like a body formed of two or more parts each
having hooked or folded non-soldered edges such as a as to facilitate engagement
with or disengagement from corresponding edges of the other part or parts,
substantially as and for the purpose described and illustrated in the accompanying
drawings.
2. In a sheet-metal chest tank or the like the combination with a body having an
outwardly folded turn-down edge such as a" of a plate or wall having a channelled
edge such as b¹ receiving the edge a with or without clips such as C or packing,
substantially as described or illustrated in the accompanying drawings.
3. In a sheet-metal chest tank or the like the combination with a body formed
of two or more parts having hooked or folded edges such as at a and turn-down edge a
of a plate or wall having a channelled edge such as b¹ with or without clips such as C
or packing, substantially as and for the purpose described and illustrated in the
accompanying drawings.
4. In a sheet-metal chest tank or the like of the kind described top or bottom
plates or walls channelled as at 62 substantially as described.
5. In a sheet-metal chest tank or the like of the kind described a clip such as C'
substantially as and for the purpose specified.
6. The complete jointed chest, tank or the like substantially as described and
illustrated in the accompanying drawings.
