This invention relates to railway cars of the
thereof, with the long axes of these doors or
hopper-bottomed dump type, as commonly used
ports extended parallel with the slopes of the
for hauling and transporting coal. In the use of
such cars experience proves that when the hopper
spondingly shaped gates of larger super?cial di
doors are opened, a certain amount of coal im
mediately at the door opening will be discharged
by gravity, but for the reason that the slope
of the hopper bottom in the usual car of this
type is not steep enough to cause the coal to slide
out by gravity alone, the balance of the coal at the
opening will jam up or arch over, which jam or
arch must be broken up and the coal forming the
same must be released and assisted down through
the discharge hopper by inserting crow bars or
other implements up through the open hopper
doors and poking or raking the coal for breaking
same loose. Furthermore such jams will be fre
quently repeated in the process of unloading a car.
Another method of loosening such jams, as fre
quently resorted to, is to pound upon the sides
of the car with hammers or other tools, and as
these cars are generally constructed of sheet metal
or steel, the result is that the cars are dented,
pitted, scarred or stove in, and thus seriously
damaged by such operations. On the other hand
it is extremely inconvenient and dirty Work for a
man to get below an open hopper door for the
purpose of inserting implements up through the
same, for the purpose of loosening a coal jam
or arch.
It is the primary purpose of the present in
vention therefore, to provide handy and conven
hopper bottoms at each end of the car, corre
5 mensions than the said ovate openings pivotally
supported at one end to the‘margins of the upper
ends of the said ovate openings and adapted to
close downwardly thereover, and latches on the
margins of the lower ends of the openings adapt
10 ed to releasably engage the free ends of the gates
in their closed positions.
A further object of the invention is to vprovide
in a hopper bottomed or dump type of railway
car of the kind referred to, the bottoms of the
15 hoppers thereof sloping from ‘either end of the
, car inwardly and downwardly towards their cen
trally located discharge doors, ovate ports, doors
or openings formed through the sides of the car
in spaced relation to the ends thereof with‘ their
20 long axes extended parallel with the slopes of
the hopper bottoms, ?at frames mounted over the
outer sides of these ports or openings and se
cured to the margins thereof, the said frames be
‘ing formed with ovate ports or openings axially
25 aligned with the ports or openings through the
sides of the car and with the margins of the
ovate openings of the frame overlying the mar
gins of the'ovate openings through the sides of
the car, ovately elongated'gates of larger super
30 ?cial dimensions than the openings of the frames,
pivotally supported at one end to the margins of
the upper ends of the openings of the frames and
ient means, incorporated upon the car, for break
ing up coal jams of the kind referred to, as same
arranged to close by gravity downwardly there
coal and facilitating its discharge through the
hopper doors.
A further object of the invention is to provide
their closed positions.

such other and additional objects and advantages

In the use of a hopper bottomed car of the
type as described, or of any similar type, the
gated openings or ports as described provide very
handy and convenient means for access to the
interior of the car, in the process of unloading
coal or other loose materials therefrom, for the
purpose of inserting crow bars or other imple
ments through the openings for breaking up jams
and arches as commonly form at the hopper doors
of such cars in the process of unloading coal.
The ovately elongated form of port or opening
as here shown and described is thought to be the
best form and best adapted for the purpose de
scribed, for the reason that such opening will
permit the working and manipulation of tools or
implements in every direction through the in
terior of the hopper, for the purpose of dislodg
ing and breaking up jams or arches as above
referred to. However any other form of port or
