PROVISIONAL SPECIFICATION.
Improvements in and relating to Metallic and Composite Boxes,
Tanks, and the like, and in Securing Lids or Covers thereto.
I, HENRY JAMES STUART BROWN of Egremont, Cambuslang in the County
of Lanark, Commercial Traveller, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in the construction of boxes tanks and
the like composed entirely of metal or having the top and bottom and one or
inore of the sides or either of them composed of wood or other material joined
to the metal parts.
Under the preferred mode of construction the box or tank has its sides made
out of one piece or sheet of metal which by stamping or otherwise has panels
formed upon it each of these panels representing the major part of the area of
one side of the box and the groove bounding the panel being dished inwards so
that at the top and bottom these grooves afford ledges or supports on which
to carry and secure the bottom and lid.
In making up the box the piece of sheet metal is bent throughout its depth
between the grooves dividing the several panels so as to give it the requisite
rectangular form and the two ends of the sheet are joined or secured together
by forming them with hooks between which a vertical staple or key is driven or
they may be soldered or otherwise joined. When so joined the bottom which is
preferably of wood is inserted in place and surrounded by a band of metal so
bent into channel form as to grip both the wood and the groove of the panel.
This band of metal is preferably in one length cut or recessed to enable it to
be bent round the corners of the box and at the points where its ends meet a
hook or clip is secured to the wood the jaw of the hook embracing the ends of
the metal band.
The top of the box which is preferably made of metal is also dished or panelled
a groove extending around near its outer edge resting upon the ledges constituted
by the grooves at the upper ends of the panels of the sides. The edges of the lid
are bent downwards so as to fit over the top of the box and it is also held in
position by a band of metal of channel form embracing it and the top of the box as
described with reference to the bottom the said band being secured either by a clip
or by a screw passed through its ends into a nut fastened to the lid.

COMPLETE SPECIFICATION.
Improvements in and relating to Metallic and Composite Boxes,
Tanks, and the like, and in Securing Lids or Covers thereto.
I, HENRY JAMES STUART BROWN of Egremont, Cambuslang in the County
of Lanark Commercial Traveller, 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:-
This invention relates to improvements in the construction of boxes, tanks and
the like composed entirely of metal or having the top and bottom or either of them
of wood or other inaterial joined to the metal parts.
Under the preferred mode of construction and which is illustrated in vertical

section at Figure 1 and in horizontal section on the liner, at Figure 2 the box
or tank has its body made in a single piece or sheet of metal which by stamping or
otherwise has panels a formed upon it each of these panels representing the major
part of the area of a side of the box. The grooves b, b1, bounding the panels are
dished inwards so as to afford ledges or supports k, k¹ on which to carry and secure
the bottom and also the lid if so desired. The box shewn has a wooden bottom c
and a metallic lid d but both may be of wood or metal. In making up the box the
piece of sheet metal is bent throughout its depth at parts equi-distant between the
grooves dividing the several panels so as to give it the requisite rectangular form
and the two ends of the sheet are joined or secured together by bending the one.
over the other as at e, a vertical staple or keyf being driven down at the joint to
cause the bent edges to lock together or the ends of the sheet may be soldered
together or otherwise joined. When joined the bottom is inserted in place and
surrounded by a band g of metal so bent inio channel form as to grip both the
bottom and the grooves 6 of the panels. This band of metal which is shewn in
detailed elevation and plan at Figures 3 and 4 respectively is made in one length
cut or recessed to enable it to be bent round the corners of the box. To secure it
in position the ends are overwrapped and fastened by a screw h passed through
them into the wood.
The top d preferably made of metal is also dished or panelled and the groove or
dented part of the panel may be sufficiently deep to rest upon the ledges con-
stituted by the grooves at the upper ends of the panels of the sides. The edges of
the lid are bent downwards so as to fit over the top of the box and the lid is also
held in position by a band 9' of metal of channel form the upper member of which
embraces the lid whilst the lower part enters the grooves b' the band being secured
by a screw h¹ passed through its overwrapped ends into the lid or into a nut
fastened thereto. To enable the ends of the bands g, g' to be overwrapped the
channel section is terminated short of one end as shewn by Figure 4 and the flat
part m is entered into the channel of the other end. By partially cutting through
the broader flange of the band at the points n and by shaping the narrower flange
at these parts as shewn by Figure 4 the band can with great ease and quickness be
placed in and removed from position and the mode of fastening the bottom and lid
in place with one screw also greatly facilitates the closing up and opening of the
box or tank. To render the joint of the lid thoroughly water and air tight a band
of rubber, cork, felt or other elastic material may be inserted where the down-
wardly bent part of the lid fits over the top of the box.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A metallic or composite box or tank having its body composed as set forth of
one piece of metal and its ends held in place substantially as described with
reference to the drawings annexed.
2. In a metallic or composite box or tank the use to hold the ends in place of a
metallic band constructed substantially as set forth with reference to the accom-
panying drawings.
