PROVISIONAL SPECIFICATION.
Improved Construction of Watertight Packing Cases.
I, ARTHUR CHARLES MOORE, of Ida Wharf, Deptford, Kent, Manufacturer,
do hereby declare the nature of this invention to be as follows:-
My invention has reference to an improved construction of water tight packing
cases, more particularly such as are intended to contain sheets of galvanized iron
and other heavy metal goods. When employing for such purposes ordinary water
tight packing cases consisting of a wooden box containing a complete lining of
soldered sheet metal, the plates or other goods in shifting about with more or less
play are apt to burst through the metal lining, thus letting in the water; or if
the box is merely lined with felt, this is not sufficiently water tight.
According to my present invention I obviate these defects by constructing the
packing cases as follows. I form the four sides of the box of strong boards, the
joints at the corners being made water tight by the interposition of suitable water
tight packing such as marine glue, pitch, and the like.
The top and bottom of the box are closed firstly by a sheet of metal, extending
to the outer edges of the sides, and secondly by a wood cover. A water tight
packing of marine glue, pitch, &c. is introduced between the edges of the sides
and the covering metal plate, and the wood cover is screwed or nailed down over
the latter. By this means the interior of the box presents four wooden surfaces
for the sides, and metal surfaces for the top and bottom, with all the joints made
watertight by packing.
Thus the sheets of galvanized iron or other material enclosed in the packing case
strike against wood surfaces in shifting during the transport and are thus prevented
from doing damage, while at top and bottom they slide upon metal surfaces which
render these comparatively large surfaces perfectly water tight and protect the
box from injury by abrasion.

Improved Construction of Watertight Packing Cases.
1, ARTHUR CHARLES MOORE, of Ida Wharf, Deptford, 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 :--
My invention has reference to an improved construction of water-tight packing
cases, more particularly such as are intended to contain sheets of galvanized iron
and other heavy metal goods.
When employing for such purposes ordinary water-tight packing cases consisting
of a wooden box containing a complete lining of soldered sheet metal, the plates
or other goods in shifting about with more or less play are apt to burst through
the metal lining, thus letting in the water; or if the box is merely lined with felt,
this is not sufficiently water tight.
According to my present invention 1 obviate these defects by constructing the
packing cases as follows.
I form the four sides of the box of strong boards, the joints at the corners being
made water-tight by the interposition of suitable water-tight packing such as
marine glue, pitch, and the like.

page_text: The top and bottom of the box are closed, firstly, by a sheet of metal, extending
to the outer edges of the sides, and secondly by a wood cover.
A water tight packing of marine glue, pitch &c. is introduced between the edges
of the sides and the covering metal plate, and the wood cover is screwed or nailed
down over the latter. By this means the interior of the box presents four wooden
surfaces for the sides and metal surfaces for the top and bottom, with all the joints
made watertight by packing.
Thus the sheets of galvanized iron or other material enclosed in the packing case
strike against wood surfaces in shifting during the transport and are thus prevented
from doing damage, while at top and bottom they slide upon metal surfaces which
render these comparatively large surfaces perfectly water tight and protect the box
from injury by abrasion.
Fig. 1 of the accompanying drawings shews a perspective view and Fig. 2 shews
a section of a water-tight packing case constructed according to my invention.
The case is constructed of four strong wood sides a a' secured together at the
corners in a water tight manner by the interposition of water tight packing bb.
The end pieces a¹ are by preference let into the side pieces a as shewn at Fig. 3,
so as to make a more perfect joint. The top and bottom of the box are constituted
firstly by sheets of metal cc extending over the outer edges of the sides, and
secondly by a wood cover dd, water tight packing being interposed between
the edges of the sides and metal sheets c c, so that when the covers d d are screwed
or nailed down as shewn at Fig. 2 with the screws or nails passing through the
sheet metal, a perfectly water tight joint is made between the metal sheets and the
sides.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is:
In packing cases, the combination of wooden sides secured together with the
intervention of water-tight packing, sheet metal covers extending to the outer
edges of the sides and fitting thereon with the intervention of water-tight packing,
and wood covers, covering the sheet metal, and secured to the sides by screws or
nails passing through the sheet metal, substantially as described.
