Improvements in Dumping Cars.
I, WILLIAM GEORGE LANE, Gentleman, of Picton, in the Province of Nova
Scotia, Dominion of Canada, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement: -
This invention relates to improvements in dumping cars and it is carried out as
follows, reference being had to the accompanying drawings, where-
Fig. 1 represents a plan view of the improved dumping car showing the hopper
removed and the doors closed;
Fig. 2 represents a longitudinal section on the line 2-2 shown in Fig. 1 ;
Fig. 3 represents a similar longitudinal section showing the doors open;
Fig. 4 represents a cross section on the line 4-4 shown in Fig. 2; and
Fig. 5 represents an enlarged longitudinal section on the line 5-5 shown
in Fig. 1.
Similar letters refer to similar parts wherever they occur on the different parts
of the drawings.
The object of my invention is to carry a load of coal or other materials in
a hopper car and means for dumping the load instantly as will hereinafter be
more fully shown and described.
in
In the drawings A represents the hopper of the car secured to the car frame B
any suitable manner.
C, C, are the wheels on which the car frame is mounted, D, represents the lower
discharge opening of the hopper, which opening is normally held closed by means
of doors E, E, which are pivoted at e, e, to the upper portion of the end pieces or
wings F, F, which latter are pivoted together in their lower ends at f, to the braces,
standards or girders G, G, secured to the car frame as shown.
To the outer ends of the doors E, E, are secured axles H, H, on the ends of
which are journalled the grooved rollers h, h, adapted to roll on rods or ways I, I,
Eecured to the car frame as shown.
On the inside of the car frame are pivoted the gravitating latches K, K,
having notches K', K', adapted to receive the lugs or locking projections F1, F¹,
on the upper ends of the wings. F, F, when the doors E, E, are closed as shown
in the drawings.
k, is a cam projection on the underside of the free end of each of the latches K
as shown.
The doors E, E, are opened simultaneously by a rock shaft L, journalled across
the frame of the car and adapted to be actuated by a lever l, secured to one or
both ends of said shaft, and to the latter are secured the levers or arms M, M, M³, M',
extending in opposite directions.
The upper ends of the arms M, M, are connected to the most distant wings F, by
means of rods m, m, and the lower ends of the arms M³, M¹, are connected to the
Dearer wings F, by means of rods m³, m', as shown.
Each rod m,
has an offset or can projection m", adapted to come in contact with
the cam projections k', ¹, on the latches K, K, during the release of the doors from
said latches.
To unload the car all that is necessary to do is to swing the lever 1, in the
direction shown by arrow in Fig. 2 by which the latches K, K, are released from
the lugs F, F, by the action of the rod projections m", m", coming in contact

page_text: with the projections ³, k³, on the latches K, K, causing the doors and their side
wings to fall by gravitation, and in so doing the said doors are caused to move
outwards by the rolling motion of the rollers h,h, on the rods or ways I, I, to the
position as fully shown in Fig. 3.
In closing the doors after the contents of the car has been discharged, all that
is necessary to do is to swing the lever l. in the opposite direction causing the
wings F, F, and their doors E, E, to be closed and automatically locked in such
closed position by the lugs F1, F1, on said wings engaging with the notches in the
pivoted latches K, K, as fully shown in Figs. 2 and 5.
N, N, are suitable chains attached to the upper portion of the wings F, F, and
to the axles H, H, as shown in the drawings for the purpose of limiting the
opening movement of the doors E, E, and their wings and to support said doors
and wings in their open position during the discharge of the load as fully shown
in Fig. 3.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
1. A dumping car having a hopper open at its lower end and a pair of doors
pivoted to jointed side pieces or wings, gravitating locking latches adapted to
secure said doors in closed positions and rollers on said doors adapted to roll on
guides or ways secured to the car frame, substantially as and for the purpose
set forth.
2. A dumping car having a hopper at its lower end and a pair of doors pivoted
to jointed side pieces or wings and gravitating latches adapted to secure said doors
in closed positions and rollers on said doors adapted to roll on guides or ways
secured to the car frame combined with a rock shaft having a releasing lever and
arms connected to the respective side wings and means for releasing the latches
during the opening of the doors substantially as and for the purpose set forth.
Dated this 6th day of November 1894.
