An energy absorption system for a railcar having an elongated sill with front and rear stops defining a pocket therebetween. To facilitate use of known railcar structures, the energy absorption system can be used in combination with a railcar also having a sill with center stops disposed between the front and rear stops. A coupler having a head portion and a shank portion is arranged in operable combination with the energy absorption system. The energy absorption system also includes a first cushioning assembly positioned in the sill pocket. A first follower is urged toward and engageable with the front stops under the influence of the first cushioning assembly and is operably engageable with a free end of the shank portion of the coupler. A second cushioning assembly is positioned in generally axial alignment with first cushioning assembly. A second follower is positioned and normally urged by the energy absorption system toward and configured to engage with the center stops. An axially elongated yoke encompasses the first and second cushioning assemblies, terminates in an open forward end, and is coupled to the shank portion of the coupler. The first and second cushioning assemblies act in series relative to each other to absorb and cushion impact forces directed against them when the energy absorption system operates in a buff direction. Advantageously, the second follower acts in concert with the center stops and the second cushioning assembly to minimize excessive system cycles while better dissipating train action energy when the energy absorption system operates in a draft direction.

An apparatus for controlling discharge of commodity from a railcar having a
hopper
with at least two transversely spaced discharge openings and two laterally
spaced and commonly
joined pivotal doors arranged in registry with the two discharge openings. The
control apparatus
includes a transversely extending operating shaft and a linkage system
operably connecting the
operating shaft to the doors. A drive mechanism is operably connectable to the
linkage system.
The drive mechanism includes a driver for selectively operating the linkage
mechanism to either
simultaneously push the doors into their closed position or to simultaneously
pull the doors from
their closed position. The drive mechanism further includes a lever radially
extending from the
operating shaft and operably connected to the driver. To releasably hold and
maintain the doors
in their closed position, a lock assembly is arranged in operable combination
with the driver.
The lock assembly can be operated in either of two operable conditions and
either in timed
relation to movement of the doors or manually. An indicator is also provided
for providing a
visual indication, from a side of the car, the operable condition of the lock.

Abrégé

A railcar energy absorption/coupling system including a cushioning assembly arranged in operable combination with a coupler and a yoke. The cushioning assembly is positioned in a draft pocket defined by a draft sill on a railcar between the front and rear stops. The yoke consists of a back wall along with top and bottom walls which are joined to and axially extending from the back wall toward a forward end of the cushioning assembly. The back wall of the yoke is disposed to contact the rear end of the cushioning assembly. The top and bottom walls of the yoke are operably coupled to a shank portion of the coupler toward a forward end of the yoke.

Abrégé

A mechanism for operating a discharge gate assembly mounted on a railcar. The gate assembly including a frame defining a discharge opening, a door slidably positioned on the frame for a generally horizontal range of movements between a closed position and an open position. An operating shaft assembly is mounted on the frame for rotation about a fixed axis and is operably coupled to the door such that the door moves in response to rotation of the operating shaft assembly. The mechanism for operating the discharge gate assembly includes a mount earned by and with the railcar and an actuator carried by the mount outside a range of travel of the slidable door. A force transfer mechanism is operated by the actuator for rotating the operating shaft assembly to slidably move the door between the closed and open positions in response to operation of the actuator.

Abrégé

A railroad freight car brake beam with a
strut having a pair of generally parallel and joined side
walls disposed to opposite sides of an axis of the strut
and having a central hollow portion along with a
longitudinally elongated slot adapted to be inclined a
predetermined number of degrees from vertical for
accommodating an elongated brake lever extending through
the strut. Each side wall of the strut defines a bore
opening to the hollow center portion and to an exterior
of the strut. The bores defined by the strut are aligned
relative to each other to accommodate at least a
length-wise portion of a brake lever pivot pin extending
through the strut and serving to connect the brake lever
to the strut. The aligned bores in the strut also define a
pivot axis for the brake lever. The strut further includes
a pair of bushings which journal the brake lever pivot
pin. One bushing is accommodated in each bore
de-fined by the strut. Cooperating instrumentalities inhibit
inadvertent displacement of the brake pin bushings
away from the axis of and relative to the strut thereby
fixing the pivot axis of the brake lever relative to the
strut.

Abrégé

A system on a railroad hopper car for providing an indication, observable by a person located either proximate to or remote from the hopper car, of a condition of a lock arranged in operable combination with a mechanism on the hopper car for controlling discharge of material from the hopper car. The system includes electric circuitry and a sensor for providing a signal when each discharge mechanism lock on the railcar is in the locked condition and for producing another signal when each discharge mechanism lock on the railcar is in the unlocked condition. An illuminable indicator, mountable on a side of the railroad hopper car, is responsive to signals from the circuitry for displaying the condition of the discharge mechanism locks. A method for visually displaying a condition of a lock on a railroad hopper car as through use of illumination is also disclosed
