2 Claims.
While I will, for the purposes of illustrating my
invention, describe it as being particularly adapt
ed for the shipment of lime and cement in bulk,
it will, of course be understood that the use of
my improved container is not limited vto these
particular commodities.
As is well known, cement, prior to my invention,
was shipped in bags and each individual bag had
to be handled both in loading ‘and unloading on
10 railroad cars and other transportation vehicles,
all of which increased the cost of the product.
Lime is usually shipped in barrels or in bulk
in box cars, requiring considerable handling in
loading and unloading, which, likewise, increased
“ the cost of the commodity.
In both of these
methods of shipment there was no real protection
against the elements for the commodity because
moisture would penetrate the bags, and in the
case of box cars a leak in any portion of the car
would affect the lime in that particular zone,
and this effect would in many instances be
straight throughout the entire area of the box
car and result in a loss of the shipment.
The object of my invention is to provide a con
tainer, preferably of less than car load lots size,
for the shipment of lime and cement in bulk
whereby the entire contents of the container
could be handled at one operation, and whereby
the commodity would be fully protected against
30 the elements.
In instances of large buildings,
it is possible by my invention to load the con
tainer at the point of shipment and ship the con
tainer with its load intact to the point of desti
nation and raise the container by a crane, or other
35 means, to the point in the building under con
struction and deposit the entire contents at the
actual point of consumption in the building, thus
eliminating a large amount of manual labor.
, Another advantage of shipping cement and
40 lime in bulk is that the percentage of loss in
shipment is materially reduced.
With__-these and other ‘objects in view, my
invention consists of the parts and combination
of parts as will be hereinafter more fully set
45 forth.

The vertical Walls of the container are pref
erably made from sheet steel, the side walls 12
being provided with vertically extending ‘corru
gations l3 which rigidify and strengthen the
walls, the lower portion of the sheet being pro
vided with a horizontally; disposed corrugation
N. If desired the side walls of the container may
be provided With-guide shoes 15 which slidably
interlock with corresponding guides secured.'_ to
the side walls of gondola cars whereby the con-' 25
tainers are held against shifting on the car, and
whereby one or more containers maybe removed
from the car without impairing the stability of
the other compartments on the car.
The end sheets, or walls, [Glare provided with
vertically disposed corrugations or rigidifying ele
ments ll of varying lengths.
1 :
As shownin Figure 11 the ‘side and end wall
sheets are overlapped at the corners and I con
nect them by means of ‘an inner post l8 'andan
outer post I9, all being suitably secured together
by means of 'the rivets‘ 2b..
Theroof 2| of the container may be of any
approved construction and type andis provided
with a hatch way 2| (see Figure '7) , andlon each 40
side of the hatch way ,I provide ‘a channel or "
other rigidi'fying iron.‘ 22,.-the flanges ‘of which
project ‘ downwardly into the container. ‘ This
hatch way is further reinforced by angle irons 23
suitably secured. A hatch door 24 having a down
wardly extending ?ange 25 around its perim
eter is provided with rigidifying beams 26 to one
end of which a hinge member 21 is suitably se
cured, the other hinge member 2'!’ being secured
to the roof 2!] and channel beam 22, as shown in
Figure '7. It will be noted that the‘ hinge joint
and members are spaced rearwardly from the in—
Wardly turned ?ange 25 of the door. At the free
end of the door I provide a locking member 28
adapted to engage the screw thread fastening 55
bolt 29 which is pivotally mounted at 30 on the
car roof whereby the door may be securely sealed
in position on the container. It will be seen from
Figure 2 that I provide the door with two of the
beams 26.
The container is provided with lifting links 3|
at each corner.
The lower end of the container is provided with
a pair of doors 32 each having depending ?anges
10 33 around its perimeter, as clearly shown in Fig
ure 5. These doors are provided with reinforcing
angle bars 34 secured to a door sheet within the
?ange 33, each end of the reinforcing bars 34 be
ing provided with an extension 35, which exten
ward past the end of each door to the end sill.
These housings are clearly seen in Figures 4, 4A
and 5. It will be noted from Figure 5 that the
lower portion of the chain housings are ?ared to
accommodate spread of the chains 40 to their re
spective doors. The joint between the top of the
chain housing and the roof of the container is
closed preferably by welding, or some other ap
proved method of sealing the joint against mois
ture may be employed.v The de?ectors 39, as 10
shown in Figure 4A, are extended around the
chain housing.
At any chain hole, or opening, 43 and to one
hinge member is secured to another hinge mem
ber 31 secured to the side sill 38, the upper end
of which member 3'! extends within the ?ange 33
of the door to a point near the underface of the
side thereof I provide a drop door chain fastener
44’, the vertical leg of which is provided with a
vertical slot 45 which is wide enough to engage
and hold the drop door chain when the doors are
in closed position, and I also provide on the roof
of the container a support 46 adapted to support
the hatch door when in open position. The chain 20
fasteners 44’ also function to support the hatch
door when it is in open position.
While I have shown and described my pre
ferred construction, it is, of course, understood
that changes may be made in the details of con
door sheet whereby this hinge joint is protected
struction and arrangement of parts within the
against the elements and leakage.
I secure a sloping lading de?ector 39 within
the container on all four sides thereof just above
30 the top surface of the drop doors, the de?ectors
being secured to the side sills 38 of the container
base and to the side sheets of the container body,
scope of the appended claims.
What I claim is:
1. In a drop bottom discharge container side
and end sills secured to the bottom of the con
tainer and constituting extensions of the walls of
the container, a hinge member secured to the end
sills with its operative end materially above the
lower edge of the end sill, a door having a de
15 sion extends out under the door ?ange, as shown
in Figure 4A. These doors must ?t accurately yet
operate freely, proper clearances being provided
for that purpose. The door is provided with a
hinge member 36 secured to its underface and
20 within the depending ?ange 33 and materially
above the lower edge of the ?ange 33, which
and are preferably mitered at their ends for con
nection at corners of containers, the connection
being preferably welded. These de?ectors not
only function to de?ect the lading toward the
door opening, but, as seen in Figure 5, they func
tion as a hood or guard sill, cooperating with the
top surface of the door to prevent leakage of the
40 lading, and also prevent entrance of moisture
into the container. It will be seen from Figure 5
that the end sills elevate the doors of the con
tainer materially above the surface on which the
container rests whereby the doors are prevented
from coming into contact with any wet surface
on which the container may be deposited, thus‘
protecting the lading.
Suitable chains 40 are connected at their low
er ends to the extensions 35 of the door stiffeners,
50 said chains being connected at their upper ends
to a common plate 40' which, in turn, is connect
ed to the lifting chain 4| having a suitable ring
42 adapted to be engaged by a suitable source of
lifting power, said chains 4| passing up through
55 an opening 43 in the roof of the container.
To completely enclose the door operating
chains, so as to preventltheir contact with the
lading, as well as prevent the entrance of mois
ture into container a U-shaped chain housing 44
is suitably secured to each interior face of the
end wall of the container, and these housings ex
tend from the underside of the roof sheet down
pending marginal ?ange and hinged to said hinge
member at its underside within the space bound
ed by the ?ange, said door being positioned when
closed in a. plane materially above the lower edge
of the end sill, a de?ector extending outwardly
from the walls of the container over the joint 40
between the ?anged edge of the door and con
tainer to prevent the loss of lading through said
joints, a member secured to the underside of the
door and projecting outwardly beyond said ?ange,
and door closing and locking means secured to
said member.
2. In a shipping container designed to dis
charge through its bottom, drop doors secured
to the bottom of the container locking means
for holding the doors in closed position and per
mitting them to open, a housing within the con
tainer completely housing said means within the
container and open at both ends, the lower open
end extending below the said doors, whereby
moisture in said housing will be discharged 55
through its lower open end outside of the con
tainers, stiffeners extending transversely of said
doors having extensions extending beyond the
edges of the doors to a point under the lower open
ends of said housings, said locking means being
secured to said extensions.
