PROVISIONAL SPECIFICATION.
Improvements in Watertight Packing Cases.
I, ARTHUR CHARLES MOORE, of Ida Wharf, Deptford, in the County of Kent,
Manufacturer, do hereby declare the nature of this invention to be as follows :-
In the Specification to my application for a Patent No. 8320 of 1891 I described
a construction of watertight packing cases for containing sheet metal and other
metal goods wherein the four sides of the case were made of wood while the top
and bottom were formed firstly of flat metal sheets that were cemented to the edges
of the wood sides by a watertight cement, and secondly, of a wood cover fixed over
the metal sheet and secured to the sides by nails or screws.
According to my present invention, when constructing such packing cases for
the transport of corrugated or stepped sheet metal, employ correspondingly
corrugated or stepped metal plates for the plates that serve to close the top and
bottom of the packing case, so that when the goods arrive at their destination,
these plates may serve as part of the goods supplied, instead of being more or less
useless, as would be the case with flat covering plates when used for a cargo of
corrugated plates.
For this purpose I prefer to construct such packing cases as follows. I make
the sides of the case of wood, secured together in a watertight manner by
cementing as before, or by a layer of felt or other similar material between the
joints. The top and bottom edges of two opposite sides I cut so as to form them
with a corrugated or stepped configuration corresponding exactly to the configura-
tion of the corrugated or stepped plates that are to form the covers, so that when
these are placed upon the sides, they will accurately fit the corrugated edges of the
latter, and they are made to form a watertight joint with these both at the
corrugated ends and at the two longitudinal flat sides by the interposition of
suitable watertight cementing or other material to exclude water or other liquid.
The wood covers to be fixed on over the sheet metal covers are by preference
provided with projecting fillets at the two ends which are formed with a corru-
gated or stepped configuration so as to fit into the corrugations of the cover plates,
while the two longitudinal sides remain flat for fitting upon the flat longitudinal
side edges of the said plates, such wood covers being fixed on by nails or screws.
In the ridges of the corrugated fillets I form transverse notches so that any
water that might penetrate into the internal hollow spaces that exist between the
flat inner face of the wooden cover and the furrows of the corrugated plate, can
escape again through such notches.
In some cases the said corrugated fillets on the wood covers may be dispensed
with and these covers are then fixed with their flat underface against the tops of
the ridges of the cover plates, being secured down upon them at these points by
nails or screws, the intermediate furrows of the plates being held sufficiently tight
against the end sides of the casing by such fixing.
The wood covers may in some cases be made as skeleton covers, that is to say,
they may consist of separate boards fixed only over the two ends of the corrugated
cover plates to a greater or less extent, and leaving the intervening part or parts
thereof uncovered, or some additional pieces in between the two end pieces may be
used.
The flat longitudinal edges of the cover plates may in that case be secured to
the longitudinal edges of the sides either directly by nails or screws driven directly
through the plates, or by wood fillets placed on top of the edges of the plates and
secured by nails or screws. Such fillets, formed with a corrugated configuration

page_text: may in that case also be interposed between the skeleton cover and the corrugated
edges of the plates.

Improvements in Watertight Packing Cases.
I, ARTHUR CHARLES MOORE of Ida Wharf, Deptford, in the County of Kent,
Manufacturer, 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 :-
In my previous Specification No. 8320 of 1891, I described a construction of
watertight packing case for containing sheet metal and other metal goods wherein
the four sides of the case were made of wood while the top and bottom were formed
firstly of flat metal sheets that were cemented to the edges of the wood sides by a
watertight cement, and secondly of a wood cover fixed over the metal sheet and
secured to the sides by nails or screws.
According to my present invention, when constructing such packing cases for
the transport of corrugated or stepped sheet metal, I employ correspondingly
corrugated or stepped metal plates for the plates that serve to close the top and
bottom of the packing case, so that when the goods arrive at their destination,
these plates may serve as part of the goods supplied, instead of being more or
less useless, as would be the case with flat covering plates when used for a cargo of
corrugated plates.
For this purpose I prefer to construct such packing cases as I will describe
referring to the accompanying drawings, Fig. 1 of which shews a perspective view
and Fig. 2 a section.
I make the ends and sides a a¹ of wood secured together in a watertight manuer
by cementing or by a layer of felt or other similar material between the joints as
shewn at bb. The top and bottom edges c c of the ends I cut to a corrugated or
stepped configuration corresponding exactly to the configuration of the corrugated
or stepped plates d d that are to form the top and bottom, so that they will
accurately fit the corrugated edges of the ends a a, and they are made to form a
watertight joint with these and also with the two longitudinal flat sides a¹ a¹ by
the interposition of suitable watertight cementing or other material to exclude
water or other liquid.
The wood covers e to be fixed on over the sheet metal pieces forming the top and
bottom of the case are by preference provided with projecting fillets & at the two
ends which are formed with a corrugated or stepped configuration so as to fit into
the corrugations of the cover plates while the two longitudinal sides e³ remain flat
for fitting upon the flat longitudinal margins of the said cover plates, such wood
covers being fixed by nails or screws.
In the ridges and valleys of the corrugated fillets e¹ transverse notches of may be
formed so that any water that might penetrate into the internal hollow spaces that
exist between the flat inner faces of the wooden covers and the furrows of the
corrugated plates can escape again through such notches.
In some cases the said corrugated fillets on the wood covers may be dispensed
with and these covers are then fixed with their flat underfaces against the tops of
the ridges of the corrugated cover plates, being secured down upon them at these
points by nails or screws, the intermediate furrows of the plates being held suffi- 5
ciently tight against the ends of the casing by such fixing.
The wood covers may in some cases be made as skeleton covers, that is to say,
they may consist of separate boards fixed only over the two ends of the corrugated

page_text: cover plates to a greater or less extent, and leaving the intervening part or parts
thereof uncovered, or some additional pieces in between the two end pieces may
be used.
The flat longitudinal margins of the cover plates may in that case be secured
to the longitudinal edges of the sides either directly by nails or screws driven
through the plates, or by wood fillets placed on the margins of the plates and
secured by nails or screws. Such fillets, formed with a corrugated configuration
may, in that case also be interposed between the skeleton covers and the corrugated
edges of the plates.
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:
Packing cases for the transport of corrugated or stepped metal plates constructed
of wooden sides and ends which are secured together in a watertight manner and
have their top and bottom edges so shaped as to fit the top and bottom covers
formed of corrugated or stepped metal plates supported by wooden backings, sub-
stantially as and for the purpose set forth.
