page_text: Improvements in Sheet Metal and Composite Boxes.
I, WILLIAM ORE, of 109 Saint Vincent Street, Glasgow in the County of
Lanark, Merchant, do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to the construction of boxes composed of metal sheets or
partly of metal and partly of wooden or composition boards and it has for its
objects to provide in a simple, inexpensive and efficient manner for securing together
of the parts of such boxes and for the formation of jointing edges adapted to make
tight joints.
Under the invention the sides and ends of the boxes or either the sides or ends
are held or bound together by means of flexible bands or straps of steel or other
metal which are placed around recesses or indentations embossed, cut or otherwise
formed in the sheets or boards of which the sides or ends of the boxes are composed,
the bands or straps being screw-threaded at their ends or having screws attached
to them. Over the screwed ends of each strap a screw threaded sleeve or nut is
fitted and turned to draw together the ends of the straps or bands the screws being
for this purpose right and left handed.
By embossing the sheets used, strength and firmness are secured with light soft
steel sheets. Projecting screwed portions of the flexible bands are kept flush with
the outside face of the box by so embossing the sheet that a suitable cavity is
formed in which these portions of the bands will lie close down when the band
has been tightened. The outside "shipping measurement" of the package is thus
made practically equal to its internal carrying cubical capacity.
The screwed up joints of these boxes will be sufficiently tight for the generality
of purposes requiring a tight and firm though not an entirely air and water-tight or
hermetically sealed package. But the use of suitable water-tight jointing material
in the jointing spaces of these boxes before screwing the bands hard up would
make them completely air and water-tight.
Where the bands are used in boxes of wood, or of wood and metal a cavity for
receiving the projecting screwing ends is scooped out of the wood, in the bottom of
which a thin sheet metal protecting plate may be placed.
The metal sheets used are preferably of sizes to suit the four sides being in one
piece and for embossing in one operation. The one vertical jointing edge is
formed by the two folded over edges being made to nest the one inside the other
with or without a strip of water proof packing material first placed in between
the two folded edges the whole being then pressed down firmly so as to lie close
upon the inside surface of the sheet whose folded edge lies within the other folded
edge of the sheet. Or the two edges to be jointed may be so rounded as to allow
the one to be inserted within the other fitting sufficiently close to secure a tight
joint and this close fitting may be accomplished by pressing down the outer jointing
round upon the inner after it has been inserted the necessary condition being that
the edges shall be firmly held together and in such a manner as to be as nearly air
and water tight as possible. In the finished box this joint has the further security
of being enclosed by the end flanges as also when necessary by one of the flexible
screw bands.
The joint in these forms might be further secured by clips when considered
necessary placed so as to grasp the folded edges described.

page_text: The joints may be formed by folding or turning in the one edge and folding the
other in Z form to engage and embrace the first mentioned edge upon pressure
being applied or by bending one edge into the form of an ogee or like curve and
the adjoining edge into the corresponding inverse curve and applying pressure to
clinch or unite the curved edges.
The ends of the box are made with edges folded over forming a flange all round
with the corners folded in and held securely by rivets or otherwise. The jointing
of the ends to the sides of the box may be in one or other of the following
methods :-
By the flexible band pressure holding the two surfaces of the flanges formed on
the ends of the sides, and the inner side of the end firmly together, or by the screw
band pressure holding the formed edges of the ends in the concave edges of the
sides, or by the band pressure holding securely the curved or rounded flanges of
ends and of sides the one inside the other fitted close together.

Improvements in Sheet Metal and Composite Boxes.
I, WILLIAM ORR, of 109 Saint Vincent Street, Glasgow, in the County of
Lanark, Merchant, 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 the construction of boxes composed of metal sheets or
partly of metal and partly of wooden or composition boards and it has for its
objects to provide in a simple, inexpensive and efficient manner for securing together
of the parts of such boxes and for the formation of jointing edges adapted to make
tight joints.
The invention is illustrated by the accompanying drawings.
Figure 1 shews a metal box constructed in accordance with my invention,
Figure 2 a box composed partly of wood and partly of metal and showing a
slightly modified application of the flexible lamb for securing the sides and ends
of the boxes in position,
Figure 3 shews the flexible bands applied to a cylindrical box or receptacle and
Figures at 5 are details hereinafter particularly referred to.
Under the invention the sides A and einds B of the Lakes as shown at Fig. 1 or
either the sides or end are held or bound together by means of flexible bands
or straps (oi steel
or other metal which are placed around recesses or
indentations I) embossed, cut or otherwise forred in the sheets or boards of which
the sides A or ends B are composed, the bands or straps C being screw-threaded at
their ends or they are each turned at their adjacent ends to embrace the head of
a screw-threaded bolt E. Over the screwed ends of each strap or over the bolts E
attached to the ends of the strap a screw-threaded sleeve or nut F is fitted and
turned to draw together the ends of the straps or bands C the screws being for
this purpose right and left handed; or the ends of the bands may be drawn
together by a single bolt and nut.
By embossing the sheets used as shewn strength and firmness are secured with
light soft steel or other sheets. Projecting screwed portions of the flexible bends C
are kept flush with the outside face of the box by to embossing the sheet that a
suitable cavity is formed in which these portions of the hands will Hic cla
down when the band has been tightened. T

page_text: of the package is thus made practically equal to its internal carrying cubical
capacity.
The screwed up joints of these boxes will be sufficiently tight for the generality
of purposes requiring a tight and firm though not an entirely air and water-tight
or hermetically sealed package. But the use of solder or other suitable water-
tight jointing material in the jointing spaces of these boxes before screwing the
bands hard up would make them completely air and water tight.
Where the bands are used in boxes of wood or of wood and metal a cavity for
receiving the projecting screwed euds is scooped out of the wood as shewn at G
Figure 2 in the bottom of which a thin sheet metal protecting plate may be placed.
One set of the flexible bands may be so placed as to cover and protect the
corners of the box as shewn at Fig. 2 in which case the bands are drawn together
by the means shewn at Figs. 4 and 5.
The metal sheets used are preferably of sizes to suit the four sides A being made
in one piece and for embossing in one operation, but each side of the box may
be a separate piece. The jointing edge or edges are preferably made as shewn
at J, Figs. 1 and 2, or as shewn at I, Fig. 1 and the joint may be soldered or have
water-proof packing material placed between the two folded edges the whole being
then pressed down firmly so as to lie close upon the inside surface of the sheet
whose folded edge lies within the other folded edge of the sheet.
The ends of the box may instead of being made as already described with
reference to the jointing of the sides be formed as shewn at H, Fig. 1 with edges
folded over forming a flange all round with the corners folded in and held securely
by rivets, solder or otherwise. The jointing of the ends to the sides of the box
may be in one or other of the methods illustrated i.e. by the flexible band pressure
holding the two surfaces of the flanges formed on the ends of the sides and the
inner side of the end firmly together, or by the screw band pressure holding the
formed edges of the ends in the concave edges of the sides or by the band pressure
holding securely the curved or rounded flanges of ends and of sides the one inside
the other fitted close together.
Figures 4 and 5 are two different arrangements shewing how all the flexible
bands C may be tightened simultaneously. The bolt E which has a right and left
hand screw thread formed on it enters nuts K over which the looped ends of the
bands C are placed, said bolt being turned to tighten the bands by the application
of a spanner.
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 :-
1. A sheet metal or composite box the parts of which are formed and secured
or bound together substantially as described.
2. A sheet metal or composite box the walls of which are grooved or indented
and are bound together by flexible bands secured in said grooves or indentations
substantially as described.
3. In sheet metal or composite boxes having grooved or indented walls the
provision of flexible bands fitted in the grooves or indentations and secured by
means of screw-threaded sleeves or nuts engaging their ends substantially as
described.
