the pressure battens 2| which are of substan
formed by threading each end of round steel
tially the same length as the horizontal dimen
sion. of the adjacent end wall, and are so located
as to provide, a groove at the end wall for. the
reception of the top edge thereof.
Normally, the bottom structure of Fig. 3 and
the top structure of Fig. 4 are manufactured in
dependently, in association-with the independ
ent manufacture of the parts constituting the
front, end and side walls, and may be shipped in
this condition to the packaging plant. It is,
however, possible to assemble the two end walls
with the back wall to provide‘ an open U-shaped
structure prior to shipment.
In any event, when the parts are brought into
the shipping room, the preferred manner of pro—
cedure is to mount such a U-shaped member in
position on the floor structure ,3, with the lower
edges of the end walls and of ‘the rear wall in
35 the. grooves provided just inside of the rear rib
l3 and of the rib pieces [4. The material is then
introduced into the opened structurev thus pro
vided (as shown in Fig. 6). In the shipment of
tin. plate, the customary procedure is to manu
facture the plate and-then clip or cut it to the
desired size. It is then given a ?nal inspection
immediately before packaging. For this purpose,
a pile of the sheets is positioned in front of, a
worker, who takes the sheets one at a time and
inspects the upper and lower surfaces thereof.
45 Experienced workers perform this‘operation very
rapidly. The sheetis then introduced into the
assembly of Fig. 6, and is caused to abut against
the walls, so that the sheet falls correctly into‘
position upon the bottom, or upon the next pre
50 ceding sheet. Owing to the clearances between
the walls, this results in the quick formation of
an accurate stack of material. It is often ad
vantageous to slightly raise the open or front side
of the container by means of a block 25 (Fig. 6),
55 which sometimes assists in assuring that the front
edges of the sheets will be at a. uniform position.
Usually, the inspector, has two’ such containers
at hand, and delivers “grade A” sheets into one
of them, while “grade B” sheets are placed in
The containers are designed on the basis of
the gage of- the material and the number of
sheets which are to be placed therein. When tin
plate is being shipped, it is customary to have the
height from, say, eleven to fourteen inches, de
pending upon the area of the particular sheets.
This means that a package will be of very great
weight, such as one or two tons. ,
When the inspector has ?lled the container to
the desired height, which ‘is somewhat less than
the height of the vertical walls, a shipping clerk
utilizes a truck to remove the filled container, and
its position is then taken by an empty container.
The withdrawn container then receives the front
stock of the proper length, they are very inex
pensive. They are preferably located close to
the angles provided by, the battens l6 and. the
walls 15, whereby they are protected against me
chanical damage. The operation of drawing
these bolts down‘ assures a tight engagement of
the weight-transmitting battens 2|
with the ,
stack of sheets, at the ends of these sheets where 25
the thickness of the pile or stack is greatest:
while still leaving a space 26.
The packages thus closed may be moved onto
cars, or transported or stored otherwise.‘ The
superposition of these packages gives no di?i- .
culty, and the superimposed packages accurately
transmit their weight through the floors, skids
and top walls, so that the weight is supported
within each container by the pile of sheets there
in: the space 26 being-maintained even under 35
extremely heavy loads.
The closed and bolted package has the upper
and lower edges of the vertical walls sealed by
the close-?tting engagement of the margins of
these vertical walls in the grooves provided at
the bottom and top structures of Figs. 3 and 4,
and it will be noted thatthe stack of sheet ma
terial has its lower surface well above the lower
edges'of these vertical walls, so, that leakage does
not .run directly tothe lowermost sheets; while '45

tion of the driving rain into the interior of the
It is preferred to manufacture the parts of
wood, for thereason that wood has a certain 50
supporting and cushioning e?ect without damage
to the edge of the sheets, andv prevents damage
' by the action of a sling chain or the like along
edges of the package. In manufacturing the
container of wood, the various parts may be made - 55
of simple shapes,’ each of the partsbeing essen
tially' a rectangular parallelo'pipedom'so that the
container may be manufactured with the least
wastage and scrap. The skids are properly lo
cated, the bottom member"! I placed thereon, and 60
the false bottom positioned: these parts are then
nailed tightly together. Similarly, the ribs and
rib pieces are positioned and nailed. The form
ing of the holes for the bolts 30 may be effected
prior to the assembly of these parts, or after the 65
bottom structure has been completed, as may be
the more convenient and expedient. Similarly,
the top’ structure and the end walls are assembled
by nailing.

As pointed out above, it is preferred to join two 70
end walls and the rear wall I‘! before the start
of packaging. For this purpose, the nails may be
driven adjacent the vertical edges of the rear wall
I1 into the battens "land into the adjacent end
of the end wall l5.

shown by the nail heads in Fig. 2.
One of the features of the present arrange
ment is that the ribs, ?anges and bolts operate
to support the vertical walls, even against con
siderable impacts of the contained material,
whereby itis unnecessary to secure either the
upper or lower edges of these vertical walls, and
