Improvements in and relating to Packing Cases for Carrying Sheet
Metal or other Goods.
I, WILLIAM HENRI LUTHER, of Petershill Road, Glasgow, Lanarkshire,
Manufacturer, do hereby declare the nature of my invention to be as follows:-
This invention has reference to and comprises a new or improved construction
or arrangement and combination of the parts of a packing case for packing fluid-
tight and carrying sheets of plain, and corrugated metal and other goods for
shipment or transit abroad, and which will enable parts of said cases to be
subsequently utilized for useful work after having served their purpose.
The improvements consist in the use of flat or plain or corrugated surfaced
sheets or plates of iron or other metal which may be either galvanized or coated or
painted to prevent rast, to form the bottom and top of the case, having the goods
to be packed placed between these two outer sheets which are effectually secured
round the sides and ends to form a complete water-tight case. This is accomplished
by having a rectangular frame of four pieces of wood or other material secured at
their ends by dovetailed, mitred, or plain joints to form the outer sides and ends of
the case between the top and bottom sheet metal plates, and this wooden frame is
made to support the main bearing weight of the packed material within the case,
instead of the top and bottom cover sheets. This is effected by nailing or securing
to these wooden beams or frames on both their bottom and top surfaces
segmental plates at each of their four end corners, and which plates may also be
continued round the outsides of the joints of the frames to form stengthening
plates, or separate L shaped straps may be used for this latter purpose. Projecting.
inetallic pieces or clips preferably convex or plain on top would be secured to the
centre of the end frames on bottom and top surfaces. While corresponding clips
preferably of a concave or flat shape on top would be secured to the surfaces
of both of the longitudinal beams or frames at intermediate distances projecting.
inwards from opposite sides, all so that these segmental and projecting plate
surfaces secured to the wooden beams will take the weight or strain or greater part.
of same of the plain or corrugated sheets or goods packed within the case, and thus
take the strain off the top and bottom binding plates. Straps of channel or
equivalent shape or wires would or may also be secured to the inside surfaces of
the longitudinal wooden beams at one or more intermediate distances apart with
their inward projecting ends supporting the goods, or these projecting ends. may
extend transversely across the bottom and top of case to further support the goods.
And longitudinal straps or wires may also be used along or around the top and
bottom surfaces of the goods.
A layer of felt, marine glue or other waterproof material would be interposed
between the surfaces of the wooden frame and the surfaces or edges of the bottom
and top metallic binding plates so as to form a watertight joint at these parts, and
these plates would be secured by L or equivalent shaped clips driven into the wood.
with their projecting parts bearing on the top of the covers and by this means the
sheets would not require to be pierced with nail holes, or these covers may be nailed
or screwed at intervals apart along their outer edges to the wooden frame. The
sheets of plain or corrugated packed metal, before securing on the top cover of case,
would or may also be secured round the edges by or equivalent shaped metal
clips driven into the wooden beams at intervals apart.
Trausverse metal strips may be fitted at intervals apart across the outer surfaces
of the top and bottom binding plates to give additional strength to the case, and:

page_text: these top and bottom plates may in some cases be each composed of two or more
small plates with jointing material at their overlapping parts.
When packing corrugated or fluted sheets the wooden ends would require to be
correspondingly fluted or grooved for the ends of the sheets to rest on, and in this
case the covers may be made to carry more of the strain of the goods.

COMPLETE SPECIFICATION.
Improvements in and relating to Packing Cases for Carrying Sheet
Metal or other Goods.
1, WILLIAM HENRI LUTHER, of Petershill Road, Glasgow, Lanarkshire,
Manufacturer, do hereby declare the nature of my invention and in what manner the
same is to be performed to be particularly described and ascertained in and by
the following statement in writing, reference being had to the accompanying
drawings, that is to say :-
This invention has reference to and comprises a new or improved construction or
arrangement and combination of the parts of a packing case, for packing fluid-tight
and carrying sheets of plain and corrugated metal and other goods for shipment or
transit abroad, and which enables parts of said cases to be subsequently utilized
for useful work after having served their purpose.
And in order that my said invention and the manner of performing or carrying
. the same into effect or practice may be properly understood, I have hereunto
appended an explanatory sheet of drawings in which the same reference letters are
used to indicate corresponding parts in all the figures where shown. Figure 1,
is a partial plan view partly in section, and Figure 2, a transverse section of a
packing case in which the top and bottom covers are formed of flat metal sheets
and otherwise constructed in accordance with one arrangement of my improve-
ments. And Figures 3 to 6 are detached detail views to an enlarged scale of
segmental corner and bearing plates and securing clips as formed in accordance
with my improvements. While Figures 7 and 8 are views corresponding to
Figures 1 and 2 of a packing case in which the top and bottom covers are formed
of corrugated metal sheets in accordance with a modified arrangement of my
improvements.
Referring to these drawings, and particularly to Figures 1 to 6,-The improve-
ments consist in the use of flat or plain surfaced sheets or plates A, A, or of
corrugated plates as shown in Figures 7 and 8, of iron or other metal, which may
be either galvanized or coated or painted to prevent rust, to form the top of the
case, having the goods to be packed placed in the space Z between these two outer
sheets A, A, which are effectually secured round the sides and ends to form a
complete water-tight case. This is accomplished by having a rectangular frame
of four pieces of wood or other material B, B, B, B, secured at their end corners
at B by dovetailed, pitred, or plain joints to form the outer sides and ends of the
case between the top and bottom sheet metal plates A, A, and this wooden
frame B is made to support the main bearing weight of the packed material
within the case, instead of the top and bottom cover sheets. This is effected by
nailing or securing to these wooden beams or frames B on both their bottom and
top surfaces segmental corner bearing and strengthening plates a, as shown in
Figure 3 at each of their four end corners B', and which plates a may also be
continued round the outsides of the joints of the frames to form strengthening
plates, or separate shaped straps a may be used for this latter purpose as shown
in Figure 7. Projecting metallic pieces or clips a' as shown in Figures 1 and 5,
preferably convex or plain on top would be secured to the centre of the end and
the longitudinal frames B on bottom and top surfaces to carry the greater part of

page_text: the weight of the packed material. While corresponding clips a' shown in Figure 1
and in detail views Figure 4, preferably of a concave or flat shape on top would be
secured to the surfaces of both of the longitudinal beams or frames B at inter-
mediate distances projecting inwards from opposite sides, all so that these
seginental and projecting plate surfaces secured to the wooden beams B will take
the weight or strain, or greater part of same, of the plain or corrugated sheets or
goods packed within the case, and thus take the strain off the top and bottom
binding plates A, A. Straps of channel or equivalent shape or wires would or may
also be secured to the inside surfaces of the longitudinal wooden beams at one or
more intermediate distances apart with their inward projecting ends supporting the
goods, or these projecting ends may extend transversely across the bottom and
top of case as shown at a to further support the goods. And equivalent
longitudinal straps or wires may also be used along or around the top and bottom
surfaces of the goods.
A layer of felt, marine glue, or other waterproof material would be interposed
as at B between the surfaces of the wooden frame B, and the surfaces or edges of
the bottom and top metallic binding plates A, A', so as to form a watertight joint
at these parts, and these plates A, A, would be secured by L or equivalent shaped
clips shown detached in Figure 6 having their pointed ends driven into the
wood B and with their projecting parts, bearing on the top of the covers A, A,
and by this means these sheets A would not require to be pierced with nail
holes or as shown in Figures 7 and 8, these covers A may be secured by nails and
washers or screws at intervals apart along their outer edges to the wooden
frame B. The sheets of plain or corrugated packed metal, before securing on the
top cover A of case, would or may also be secured round the edges by Lor
equivalent shaped metal clips driven into the wooden beams B at intervals apart.
Transverse metal strips similar to a¹ may be fitted at intervals apart across the
outer surfaces of the top and bottom binding plates A, A, to give additional
strength to the case, and these top and bottom plates may in some cases be
each composed of two or more small plates with jointing material at their over-
lapping parts.
When packing corrugated or fluted sheets the wooden ends B would require to
be correspondingly fluted or grooved as shown in the end section Figure 8 for the
ends of the sheets to rest on, and in this case the covers A may be made to carry
nore of the strain of the goods.
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.-
First, the construction or arrangement and combination of the parts and
securing fittings of packing cases, substantially as herein described in reference to
and shown in Figures 1 to 6 and 7 and respectively of the accompanying
drawings.
Second. The constructing of packing cases with wooden end frames and plain or
corrugated top and bottom sheet inetal covers, substantially as described in reference
to Figures 1 and 2 and 7 and 8 respectively of the accompanying drawings.
Third. Packing cases fitted with the segmental bearing and securing plates or
clips described and shown in reference to Figures 1 to 6 of the accompanying
drawings.
