Chests or Boxes.
We, JOHN EBENEZER HOPKINSON of Westfield, Southborough Rise, Surbiton in
the County of Surrey Engineer and HERBERT RUMSEY of St Hildars, St Margarets,
Twickenham in the County of Middlesex Engineer 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 to a novel construction of chest or box for the reception of
Tea and other articles whereby we facilitate the carriage of the empty box or chest
while giving it increased durability and lightness.
For this purpose we construct the chest or box of sheet metal, preferably in three
distinct parts or sections, and of a form ensuring the utmost simplicity in its
construction whilst rendering it impervious to damp or moisture.
We will now proceed to describe our Invention by reference to the accompanying
sheet of Drawings upon which
Figure 1. Represents a perspective view of an improved chest or box embodying
our improvements.
Figure 2. Being a cross section through the same with cover partly withdrawn.
Figure 3. Is a detailed view showing construction of cover plates with hand hole
for sampling contents of box.
Figure 4. Shows the method of seaming the side of chest or box.
Figure 5. Illustrates the plate A for forming the sides of the chest or box.
Figure 6. Represents a vertical section through the chest, cover plate and
bottom.
Figure 7. Represents a modification of the above arrangement for closing the
chest; the cover being made double so as to grip the mouth of the chest on
all sides.
Figure 8. Is a further modification of the cover shown in Figure 1.

page_text: E. Wooden rail to which the cover of chest or box is secured when closed, by
screw or other fastening e. e' piece of felt or suitable material interposed between
plate C and rail E to make a tight joint.
F. Bead or corrugations formed upon plate A for the purpose of strengthening
sides of chest.
G. Socket for key for locking and unlocking plate securing cover of hand hole.
H. Plate for securing cover on hand hole.
I I. Projections formed upon cover C.
In constructing a chest or box according to our improvements we first cut out,
or otherwise shape, a plate A (see Fig. 5) so that it can be readily folded to form
the four sides of the chest or box; upon this plate (preferably coated with lead) we
form suitable beads or corrugations F for the purpose of strengthening the sides of
the chest or box and securing the bottom B and cover thereto, these beads or
corrugations being formed by means of rolls, in the ordinary manner, or by any
suitable means.
We also make in this plate A a series of slight indentations a at suitable distances
apart, for the purpose of indicating and facilitating the bending of the plates as
required.
The bottom plate B, as will be seen upon reference to Fig 6, has a beaded
flange F formed all round, which enters within the corresponding bead or
corrugation F, formed at the lower part of the plate A, when the bottom B is
forced therein, these flanges being formed either by stamping or bending up the
outer edge of the plate after it has been corrugated.
In making the cover plate C we raise a flange upon three of its sides only; each
flange having formed upon it a bead or corrugation F corresponding to that upon
the chest or box A.
By this construction of the cover C with only three flanged sides we are enabled
to slide or force it upon the chest or box A until it completely closes the mouth of
the same; in which position it can then be secured by means of one or more
screws e, or other fastenings, to the rail E, made of wood or other suitable material,
and attached for this purpose to one of the end plates of the chest A by rivets, or
otherwise.
In the centre of this cover plate O is an opening fitted with a suitable cover
plate D, through which a portion of the contents of the box can be withdrawn for
the purpose of sampling, or otherwise, without removing the entire cover-To
effect this we form the lid D of two distinct plates D and H, these plates being
united by means of a centre stud rigidly secured to the lower plate H and arranged
to turn within the upper plate D. In the centre of this stud is a recess or socket
to receive a key. The outer ends of the lower plate are tapered so as to cause the
two plates C and D to be closely drawn together when the plate H is turned
round by means of the key.
We may prefer to form this cover C as shown on Fig. 7, where the flanges of the
cover are made double so as to fit closely on either side of the chest or box A, in
which case we dispense with the rail and screws; or we may construct this cover
as shown in Fig. 8, in which case the projections I I are folded one on the other so
as to enclose the end of the box and secure the lid in its closed position, in which
case also we dispense with the rail and screws.
".
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. A metal box or chest, consisting of a middle section having a top and bottom
secured thereto by the setting of a bead on the one within a groove or bead on the
other, the said middle section having only one vertical seam or joint and the top
and bottom being without vertical joint, substantially as set forth.
2. The rail E for securing the cover C substantially as described.

page_text: 3. The hand hole in the cover plate C constructed as shown Figure 3, the
plate D being secured in its closed position by the turning of the plate H to the
position shown Figure 6, by means of a key, or otherwise.
4. The double flanged cover C substantially as shown Fig. 7 for the purpose
specified.
5. The cover C₁ with its projections L. I. for sealing the box or chest sub-
stantially as described and shown Figure 8.
