mounted on the car or truck frame are connected
together in pairs and are adapted to engage and 5
eliminate waste space at the car ends and between
containers and to reduce the actual truck orv car
structure to the minimum length for a standard
transportation, the paired jacks being connected
‘ 15 mounted on the car or truck body, which pockets
are adapted to receive the clamping jacks for
holding the containers in place so that the ends
of the containers may more closely approach the
end of the car body and the adjacent ends of
20 containers on a car body built to accommodate
more than one container may be brought into
close proximity, the jacks being arranged on the
car body under the containers in such a manner
as to enter the pockets to clamp the car body
25 securely, the said jacks being arranged in pairs
?led September 6th, 1935, (now Patent 2,072,988,
dated March 9, 1937) in that jacks slidably
hold the removable goods containers during
to the car or truck frame through a spring me—
dium which absorbs endwise shocks imparted to
the frame or chassis and obviates the transmis- 10
sion of such shocks to the containers which are
supported upon rollers on the deck of the car or
truck.
,
In the construction illustrated in the said pat
ent, as also in other structures which are publicly 15
known, jacks are arranged on the car structure to
engage ?ttings on the ends of the containers and
accommodation is provided in the length of the
car or truck for the arrangement of such jacks
beyond the ends of the container.
,
of each pair of longitudinally‘ disposed jacks are
connected together by rods 4 which extend hori
connected together and connected to the car
zontally toward each other and the inner ends of
these rods are connected to blocks 5 which are tied

tive arrangement of the container holding jacks
and the containers equipped with my improved
pocket structure for housing the engaging ends of
the jacks.

closed in my co-pending application No. 39,404,
in position upon the car in such a manner as to

10 saving in construction costs and cost of operation
and maintenance.
The principal features of the invention consist
in the novel arrangement of pockets in the under
side of the goods containers which are removably
35
(01. 105—-366)
The principal objects of this invention are to
provide a car or truck adapted for transporting
removable goods containers with shock absorbing
equipment and means for securing the containers
together by a rod 6 and a compression spring ‘l
encircling the rod 6 is engaged by inwardly mov
able sleeves B which are ?anged so that they can 30
move only in an inward direction toward the
centre of the car.
It will be seen that the endwise connection
between the jack blocks 2 is inextensible and that
the jacks when clamped against the container 03 5
body will hold it securely, but the jacks can move
longitudinally in unison and their lengthwise
movement is cushioned by the spring 7 all of
which construction is set forth in the said patent.
According to the present invention the con as
tainers 9 are provided with a special form of
corner structure in the form of a rectangular cast
ing [0 which is hollow on the underside and has
an open outward side, thus forming an underside
corner pocket and at the inward end of this cast- 45
ing is provided a socket member H which has a
semi-circular ?ange l2 which opens outwardly to
the side of the car and is adapted to receive the
?anged end I3 of the jack screw M, which screw is
threaded in the upper end of the jack I so that 50
the container may be positively interlocked with
the holding jacks in the manner set forth in my
copending application 8,685, ?led February 28th,
1935, but in the present case the actual socket
member is preferably cast integral with the corner 55

pocket casting and is housed therein so that it
does not project beyond the ends of the container,
but is actually spaced inwardly therefrom in the
fore and aft direction to enable the upper end of
the jack and jack screw to be also accommodated
or housed in the pocket recess when raised so that
no part of the same projects beyond the container
either at the ends or the sides.
This corner socket casting is suitably reinforced
It) by vertical ribs ii‘: on the inward side and at the
outward end is provided with an upwardly pro
jecting right-angular corner piece I6 which nests
within and is rigidly secured to the right-angular
corner piece ll of the frame of the container 9.
The recessed castings to extend well inwardly
from the fore and aft ends of the containers so
that the jacks are disposed well in under the con
tainer ends when they are secured in place, but as >
the jacks are adapted to be swung outwardly and
downwardly when the container is to be removed
from the car or truck, they swing freely outward
through the open sides of the castings I 0 and the
jack screws
readily accessible for manual
operation from the sides of the car when the jacks
are in the raised position for the purpose of turn
ing same to either lock or unlock same with the
socket members it at the inner ends of the cast
ings i8.
Where this invention is applied to a railway car
where two containers are arranged end to end, the
ends of the containers may be brought into very
close association as no space is required between
dated within said corner recesses to lock said
jacks to said containers with the jacks accommo
dated therebelow, said recessed corner structures
opening downwardly and outwardly to provide for
lateral entry and removal of said holding jacks
and to render the lock means accessible for man
ual operation from the side of the car.
2. The combination with a container-carrying 10
car having holding jacks slidably mounted there
on for shock-relief displacement and pivotally
mounted to be swung in lateral planes to an up
right container-holding position above the deck
surface and having lock portions displaceable 15
relative to the jacks, of a container for detachable
mounting on said car deck adapted to embrace
said jacks when they are in their operative posi
tion above the car deck and formed with pockets
at the ends opening downwardly and laterally and 20
adapted when the jacks are swung upwardly to
receive and house the entire upper end portion of
the upwardly swung holding jacks, and lock
means Within said pockets registering with said
displaceable lock portions of the jacks and 25
adapted to receive the said displaceable lock
portions only when said jacks are in their up
wardly swung position housed within said con
tainer pockets, said end pockets being of such
length in the fore and aft direction as to permit 30
manual operation of the locking portions of said
housed jacks from the side of the car into and out
of locking contact with said lock means in the
them for a holding jack, but the jack is arranged
underneath the end engaging the structure within
the corner pocket. Also at one end of the car, the
pockets.
jack may be arranged so as to allow the container
to extend completely to the end of the car (as best
car having holding jacks slidably mounted there
on for shock-relief displacement and pivotally
shown in Figure 7) , but as herein shown, where
the structure is provided on a freight car, provi
40 sion may have to be made at one end of the car for
a hand brake for the car (as best shown at the
right hand end of Figure 1), consequently this end
of the car extends past the end of the container.
but not as far as would be required if the jacks
were required to be outside the ends of the con
tainer.
It will be appreciated that where the jacks are
arranged underneath the containers as herein
shown and described, the total length of the car
may be considerably reduced and space heretofore
wasted will be eliminated at the car ends and
between the containers and as the car is short
ened the wheel base is also reduced. Further, the
resultant reduction of stresses on longitudinal
55 members makes it possible to reduce the car
Weight materially.
A socket arrangement can be provided in this
manner in the construction of the container
which will in no wise reduce the strength of the
container, but rather it may be increased, as the
corner castings on the container act as a base for
the container corner posts and rigidly connect the
end, intermediate and side rails at each corner.
