of the container sides to constitute the bottom of
the container. The actuation of these doors is
eifected by means of chains secured to the free

carrying lifting eyes or hooks. These eyes are
adapted for engagement with hooks provided on

The considered containers are provided, addi
tionally, with hooks adapted to be engaged by
lifting hooks on the crane by means of which
the containers may be lifted, lowered and trans

.
The container embodies end walls "-14 which,
as clearly shown in Figure 2 of the drawings, are
provided with reinforcing corrugations 15-15.
The end walls H extend from the top of the con
tainer and terminate above the bottom of the
75 container, as indicated at iG-IG.
and embodies preferably a plurality of metallic
sheets which may be corrugated, as indicated at
24. The cover member is formed with depending 25
marginal side ?anges 25 secured to the top re
inforcing angular members l1. The cover mem
ber is also provided with depending marginal
end ?anges 26 secured to the angular reinforc
ing members i8. It is preferred that the con 30
tainer, which is to be utilized for the shipment
of bulk materials, be formed with a hopper
construction and to this end slope sheets 21-21
are utilized. Each of the slope sheets extends
between the side walls of the container and is 35
secured at its upper margin to the lower margin
of an end sheet by means of ?anges 28-28. From
these points of securement the slope sheets 21
extend downwardly in converging relationship
andterminate above the bottom of the container 40
de?ned by the angular members 20-2I. At their
lower ends the slope sheets are spaced apart, as
clearly shown in Figure 1 of the drawings, to
provide an opening for the discharge of material.
As clearly indicated in Figures 1 and 2 of the 45
drawings, the slope sheets 21 are preferably re
inforced by means of integral corrugations 29.
Mechanism is provided in accordance with the
instant invention in order to control the dis
charge opening in the bottom of the hopper which
is provided by the hereinabove described associa
tion between the slope sheets and the end and
side walls of the container. For this purpose
there is secured to each of the side walls at the
ends of the opening in the hopper a supporting 65
bracket 30. Each of the brackets 30 comprises
an attaching ?ange 3| by means of which the
bracket may be fastened to a side wall. An at
taching ?ange 32 provided at the lower margin
of the bracket is utilized to secure the bracket to 60
the angular reinforcing member 20. Each
bracket, additionally, is formed with a plurality
of spaced extensions 32, 33 and 34, disposed as
clearlyindicated in Figure 4 of the drawings.
There is provided, additionally, a bearing mem 05
ber 35 for a purpose hereinafter explained. A
substantially cylindrical ?ange 36 extends from
said “bearing member in spaced relationship to
an opening 31 formed therein. A depending
?ange 38 is provided on the cylindrical ?ange 35,
the ?ange 33 being disposed in spaced relationship
to the bearing member 35 and being provided
with _ recesses
39-39 ‘preferably
disposed in
diametrically opposed relationship. The asso
ciation .of a bracket member 30 with a container

relationship with the extension 32 of each of the
25 bracket members and are secured thereto as by
means of rivets 46. Additional angular mem

50 and 5| these members are adapted to abut
against the metallic strips 61 which, therefore, 25
serve not only to prevent loss of the material
in the container but, as clearly shown in Figure 5
of the drawings, function to limit closing move

it is impossible to disengage the crank from
the shaft. By virtue of this construction it is
manifest that the crank can be disengaged from
the shaft only when the closure members are in
their closed position, thereby assuring against
10 loading of the container when the closure mem
bers are open.
It has been set forth herein that means is pro
vided in order to limit the closing movement of
the closing members 50 and 5|. Means is also
15 provided to limit the opening movement of said
closure members, this opening movement being
limited by the engagement between the projec—
tion 60 formedat the ends of the closure mem
bers and the lug 6| provided on each of the
20 bearing member‘s'30.
The closure members 50 and 5| when in their
closed position are adapted to be maintained
in said position by the equal pressure upon the
curved walls 52 and 55 of said closure members
25 exerted by the material in the container. It is
preferred, additionally, to construct the rib 56 of
the closure member 5| of greater section and,
hence, greater weight than the longitudinal rib
54 of the closure member 50.
In this manner
30 additional weight is given to the closure mem
ber 5| tending to over-balance the closure mem
ber 5| when the closure members are in closed po
sition and thereby maintain said members in said
position.
35
A positive locking means may, however, be
utilized for this purpose.
Such a locking means
is illustrated in Figures 9 to 12 inclusive. In the
form illustrated there is utilized a hollow shaft
‘I3 within which is fastened a plug ‘I4. A cylin
40 drical member ‘I5 is inserted within the end of
the shaft ‘I3 and is slidably maintained therein.
Studs ‘IE-‘I8, which may advantageously be
threaded into the cylindrical member ‘I5,>extend
therefrom through openings ‘I‘I-1‘I’formed in the
45 shaft ‘I3.
These openings, as clearly illustrated
in Figure 9 of the drawings, are elongated in the
direction of the‘length of the shaft thereby per
mitting the sliding relationship of the cylindrical
member ‘I5 within the shaft, while at the same
50 time compelling rotation of the cylindrical mem
55
60
65
70
ber with‘ the shaft. A spring ‘I8 is disposed be
tween the inner end of the cylindrical member
‘I5 and the adjacent end of the plug ‘I4. One
end of the spring bears against the cylindrical
member, while the other end bears against the
plug. Where the face of the shaft ‘I3 is not
smooth it is preferred to provide the plug ‘I4
with a stem ‘I9 upon which the spring ‘I8 is placed
and which extends into the cylindrical member
‘I5 which is then in the form of a hollow cylinder.
By this means irregularities in the face of the
shaft will not adversely affect the sliding move
ment of the cylindrical member. The end of the
shaft ‘I3 is recessed diametrically at opposite
points, as indicated at 80-80. The outer end
of the cylindrical members ‘I5 overlaps a portion
of the recessed end of the shaft. Bearing mem
bers 8| secured to the side walls of the container,
as hereinabove described, are formed to provide
locking abutments for the studs or detents ‘IS-‘I6.
To this end the bearing portion 82 of the bracket
member 8|, within which the shaft 73 is jour
naled, is formed with opposed semi-cylindrical
recesses 83-83 adapted to receive the detents
75 16-16 in the closed position of the closure mem
closure members 50 and 5| to open position is
prevented.
In order to permit rotation of the closure mem
bers 50 and 5| to open position for the purpose
of discharging the material within the container,
a’ crank member 84 is employed. The crank 10
member is provided with an angularly related
cylindrical portion 85 formed at its ends with
oppositely disposed ears 86-86. These ears are
adapted to be received within the recesses 80-80
formed in the end of the shaft ‘I3 when the crank
members are associated with said shaft for the
purpose of rotating the closure members. The
ears 86-86 are adapted to be inserted through
recesses 8‘I-8‘I formed in the cylindrical ?ange
88 provided on the bracket member 8|. This cy 20
lindrical ?ange 88 is otherwise continuous as de
scribed in connection with the cylindrical ?ange
38 of the bracket member 30 whereby, upon angu
lar movement of the crank member 84, interlock
ing engagement between ears 86-86 thereof and 25
cylindrical ?ange 88 will be had, preventing dis
engagement of the crank member from the shaft
until the closure members are in their closed
position. As the ears 86-86 enter the recesses
80-80 provided in the end of the shaft ‘I3 they 30
engage the end of the cylindrical member ‘I5 and
force said member inwardly against the pressure
of the spring ‘I8. As the cylindrical member
moves inwardly the detents ‘I6 are moved there
with in the recesses ‘I‘I-‘I‘I provided in the shaft, 35
thereby causing disengagement of said detents
from their cylindrical abutments 83 provided in
the bracket member 8 I. Upon the disengagement
of the detents from their abutments the shaft
‘I3 and, consequently, the closure members 50 and 40
5| mounted thereon, may be rotated so as to '
expose the discharge ports 4| and 42, whereby
the lading within the container may be dis
charged.
After the closure members 50 and 5f have been 45
rotated to their closed position so as to effect
alignment between the ears 88-88 on the crank
84 and the recesses 81-8‘! in the cylindrical
?ange 88, the crank may be removed. Upon the
removal of the crank the spring ‘I6 will again 50
be effective to urge‘the detents ‘I6 into the semi.
cylindrical recesses ‘I3 provided in the bracket
member 8|. Attention is invited to the fact that
while oppositely disposed ears, as illustrated on
the crank member 84 as well as on the crank 55
member 88, are provided, the structure of the
crank is not limited to this disposition of the
ears. It is preferred, however, inasmuch as this
arrangement of the ears on the cranks permits
the closure members to be operated both from 60
below as well as from above. If this facility of
operation is not required, it is evident that only
a single ear and, consequently, a single recess in
the cylindrical ?ange need be provided.
The employment of the positive locking mech
65
anism above described obviates the need for the
heavy counter-balancing rib 56 provided on the
closure member 5|. In its place a rib “R”, illus
trated in Figure 11 of the drawings, may be uti
lized, this rib being similar to the rib 54 provided 70
on the closure member 50.
It will be apparent from the construction above
described that the amount of exposure of the
discharge ports effected by rotation of the closure
members may be varied at will between the ex
76
5
2,126,949
treme positions of said closures. By this means
the amount of the material within the container
to be discharged at any given time_or at any
given place may be controlled. It will also be
apparent that by the provision of discharge ports
asset forth a given amount of exposure of the
discharge ports may be had with only half of the
angular movement of the closure members that
would be required for a single discharge port.
Lifting hooks 89 secured to each of the upper
corners of the container may be utilized to obtain
securement of said container to a hoist mech
anism in order to lift the container and deposit
it at any desired point.

The charging‘ port for the container is provid
ed by an opening 90 preferably rectangular in
shape provided in the cover member of the con
tainer. The margins of the sheet metal formed
in the cover member by means of the openings
20 which extend parallel to the ends of‘the contain
er may be reinforced by means of angular mem
bers 9 l-—9l extending preferably from side to side
of the container and secured thereto by means of
clips 92-92 disposed on opposite sides of the ends
25 of the reinforcing members. ' Av frame.93 is secured
to the metallic sheet 23 around the opening 90
formed therein. The frame-93 is substantially
angular in cross section and embodies a horizon
tal leg 94 riveted to the adjacent margin of the
30 metallic sheet 23 and to the reinforcing angular
members 9|. The frame comprises also a verti
cally extending leg 95 from which a ?ange 96 dis
posed intermediate the ends of the leg 95 ex-~
tends outwardly. A closure member 91 is hinged
35 to the frame 93, as indicated at 98, said closure
member being adapted to be disposed upon the

peripheral ?ange 99 and effective to change the
direction of ,air tending to enter the opening and
thereby the velocity of such air. The ?ange 96,
shoulder I00 and upper portion of the leg 95 co
operate, additionally, to provide a tortuous path
for any air carrying foreign particles such as
rain and the like’, whereby to prevent the entry
60 of air and such particles into the-container. It
will be apparent, therefore, that the container is
well adapted to carry materials‘ which would be
adversely affected by moisture and the like.
The instant invention, therefore, presents clo
sure means for discharge ports of a container
which is extremely simple and sturdy in con
struction, and economical. There is utilized with
this construction only a single shaft upon which
the closure members are mounted.
The closure
members, therefore, rotate simultaneously in the
same direction when the discharge ports are
opened and when they are closed.

modi?cations of the details of the instant in
vention may be resorted to by those skilled in ‘the
opening to provide a pair of discharge ports, op
posite bearings on said container, an operating
shaft journaled in -said bearings, means com
prising a'curved member secured to said shaft
for rotation therewith, a discharge opening
