PROVISIONAL SPECIFICATION.
Improved Dumping Car.
I, WILLIAM WILSON HORN, of the firm of Horn & Son, of 151 Strand, London,
in the County of Middlesex, Patent Agent (a communication to me from abroad by
John Riley Robinson, and William Phinehas Searls, both of New York, New York
State, United States of America, Gentlemen), do hereby declare the nature of this
invention to be as follows:-
The object of this my invention is to provide a railway or other car which is
capable of being readily unloaded as and in the manner hereinafter described.
I provide in combination with a car-platform, a duplex dumping body or box
divided longitudinally along the middle of the car, and both parts are pivoted at the
ends on suitable supporting-bearings by trunion pivots, so as to dump at the sides of
the car, respectively.
The said parts of the box or body are preferably made of boiler or sheet metal plate,
reenforced with longitudinal and transverse strengthening-bands, to which the trunion
pivots are attached.
In unloading the car, the dumping boxes are turned over on the trunion-pivots to
right and left, as will be readily understood.

COMPLETE SPECIFICATION.
Improved Dumping Car.
I, WILLIAM WILSON HORN, of the firm of Horn & Son, of 151 Strand, London,
Middlesex, Patent Agent, do hereby declare the nature of this invention, (a com-
munication to me from abroad, by John Riley Robinson, and William Phinehas
Searls, both of New York, State of New York, United States of America, Gentlemen,)
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This by invention consists of a car body or box made in two parts divided from
each other longitudinally along the middle of the car and separately mounted on
trunnions at the ends in an arrangement facilitating the dumping of the same on the
respective sides of the car, as hereinafter fully described, reference being made to the
accompanying drawings, in which-
Figure 1 is a side elevation of my improved dumping-car. Figure 2 is a plan
view, and Figure 3 is an end elevation.
At or near each end of the platform a, I arrange the standards b, about half the
height of the boxes c, and preferably extending across the platform in one structure
for the bearing supports of the boxes, which extend the whole length of the space
between said bearing-supports and have the trunnion pivots or journals & mounted in
suitable bearings e thereon, said boxes being as wide as is practicable for being thus
placed side by side longitudinally of the car, and also being of suitable bucket shape
in end section for discharging freely when turned over for dumping, as indicated by.
the dotted lines at the right hand of Figure 3-that is to say, having the over-
projecting top and backwardly-sloping outside from the top downward. The boxes
are so pivoted that when loaded in proper trim they will naturally keep their
upright position, but may be overturned with moderate effort by the hands of one or
two persons.

page_text: Along the middle of the car lengthwise, I provide a strong upright frame, con-
sisting essentially, of the posts fand beam g, and being a little higher than the top of
the boxes, and having hooks i to secure the boxes for safety while loading and running
by engaging the eye-studs ; on the boxes, but capable of easy disconnection when the
boxes are to be dumped.
The boxes are constructed of boiler-plate, and are re-enforced at the middle, both
longitudinally and transversely by strong metallic bands kl, of suitable capacity for
stiffening the plate as needed, and the trunnions are attached to the band by their
flanges m and bolts or rivets n.
It will be seen that the construction is very simple and the contrivance entirely
practical and very useful. The advantages are obvious in comparison with the boxes
dumping on one side only, or with those having a bottom sloping from the middle to
each side with the sides arranged as gates opening outward.
The invention is designed more particularly for ore-cars; but it is alike useful for
dumping-cars for any purpose.
The invention is designed to convert the ordinary platform-car into a practicable
dumping-car, whereof the box is divided along the middle only and into two parts
only.
'
Having now particularly described and ascertained the nature of my said inven
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The combination, with the car-platform, of the standards extending across the
platform, one at each end, and two dumping-boxes extending from one to the other of
said standards, side by side, and pivoted thereon by trunnions attached to the ends,
said boxes having the dumping-bucket shape formed by the over-projecting top and
backwardly-sloping outside from the top downward.
2. The combination, with the car, of a duplex dumping body or box divided longi-
tudinally along the middle of the car and both parts pivoted at the ends on the
supporting-bearing by trunnion-pivots, so as to dump at the sides of the car,
respectively, said parts of the box or body being made of boiler or sheet-metal plate
and re-enforced with the longitudinal and transverse strengthening-bands, and the
trunnion-pivots being attached to the longitudinal strengthening-bands, substantially
as described.
