I, JOHN R. WILSON, of 95 Fifth Avenue, Pittsburgh, in the County of
Allegheny, and State of Pennsylvania, United States of America, Manufacturer,
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 dumping apparatus; and it has for its object to provide
an automatic dumping apparatus for automatically dumping ore and coal or other
material through floors or the ordinary trestle-work supporting the tracks which
will be particularly efficient in its work, while at the same time the dumping
apparatus will be simple in construction and easy of manipulation.
The primary object of the invention is to provide an apparatus which will provide
for the automatic releasing of the emptied car or wagon at. the same time that the
loaded car or wagon is travelling to the point at which it will be automatically
dumped, and to this end to provide such an apparatus as is set forth by this
Specification.
•
With these and many other objects in view, which will readily appear as the
nature of the invention is fully understood, the same consists in the novel con-
struction, combination, and arrangement of parts hereinafter.more fully described,
illustrated, and claimed.
In the accompanying drawings
Figure 1 is a side elevation, partly in section, of a dumping apparatus constructed
in accordance with my invention, illustrating one car dumping and the loaded car
checked upon the main portion of the track.
Fig. 2 is a top plan view of the same.
Fig. 3 is a detail plan. view of a section of a track provided with a dumping
device constructed in accordance with a modification when one or more dumps are
required on the same track at the same point of operation.
Fig. 4 is a detail in perspective of one of the stop horns.
Fig. 5 is a similar view of the press lever.
Referring to the accompanying drawings A represents the upper portion of a
trestle-supported frame, to the top of which is secured the rails B, forming a track
upon which the dumping cars or wagons Care adapted to travel and be automatically
dumped at the point of dumping in the line of the track, and from which point
after said cars or wagons are dumped the. same travel down the inclined portion D
of the track to be refilled in the ordinary manner.
The tilting rails E form a continuation of the main rails B of the main portion of
the track and are mounted upon or connected with the transverse axle or shaft F,
journalled in the boxes f, located near the end of the frame timbers at the point
where the cars C are to be dumped, and said tilting rails are connected with said
axle or shaft at any given position to suit the various lengths and constructions of
the dumping wagons or trucks, so. that the same when filled will tilt the rails until

page_text: uumped, and wheir emptied or partly emptied, as desired, will cause said rails to
resume their normal positions in a line with the rails forming the main body of the
track.
Forming a portion of the inclined track D are the hinged or pivoted rails G,
pivotally mounted upon the rods, g located directly in front of the ends of the
inclined rails, and said swinging rails G are halved onto the dropping ends of the
rails E, and are provided at said ends with the longitudinally-disposed slots g', in
which are designed to work the projecting ends of the cross-rod 9³, connecting the
ends of the tilting rails E and extending to either side of the same. The connection
between the hinged and tilting rails allows the connecting ends of the same when the
loaded wagon or truck tilts the tilting rails to drop downward through the portion
of the frame-work at which the dump is located, and thus allows for the different
positions that the said rails must assume when the same are thrown down and up,
respectively, and when their normal positions provide for a continuous track over
and down which the emptied or partly emptied truck travels.
A series of bridles H brace the tilting rails E apart, and are also adapted to
carry the devices and mechanism used in connection therewith. To the outer
projecting ends of one of the intermediate bridles H are pivoted the ends of the
opposite stop and releasing horns I, extending longitudinally of said rails and
provided with upturned ends h, projecting above the top of said rails and normally
fitting close thereto, in order to engage the tread of the forward wheels of the
truck upon said tilting rails, and the curved or stop ends of said horns are so
disposed with relation to the tilting portion of the track that the weight of the
truck is sufficient to tilt the track and thus dump the contents thereof through the
supporting frame or through the floor, as the case may be, which supports said
track, and when said truck has discharged or partly discharged the contents thereof
the track will resume its normal position and the truck will be released in the
manner to be described.
Horizontally and centrally pivoted to the connecting braces at the dumping
end of the tilting portion of the track is the horizontal T-shaped lever J, to the
opposite ends of the head of which are pivotally secured the opposite horn-
controlling rods j, also connected to the opposite horns I, located upon the outside
of the opposite rails E, comprising said tilting portion of the track. Opposite
retractile springs 11 are secured to the intermediate bridle and to the hook or
stop ends of said horns, so that after the rods ; have forced said horns outward
and out of the path of the rails of the track the said springs will withdraw said
horns back and in contact with the sides of the rails, in order to catch and hold
the next succeeding car or wagon to be dumped. An operating-rod K is pivotally
connected to the outer end of the stem or arm of said T-shaped lever, and extending
longitudinally of the tilting portion of track is connected to the depending.arm k,
projecting below the point or pivot and operated by the upwardly extending press-
lever L. The said press-lever L is pivoted at 1 to one of the braces H at one end
of the tilting rails and between the same, and said press-lever extends above the
plane of the track and is provided at its free or swinging end with a stop-flange 1,
that is designed to work beneath one of the connecting braces H, and thus form a
stop for said press lever when the same assumes its normal position, extended above
the plane of the tilted track.. It can be readily seen now that after the truck
held upon the tilting track by the horns connected therewith has been dumped of
its contents the tilting and hinged track sections will resume their normal positions
in a line with the main portion of the track. The tilting track having assumed
its position in line with the main portion of the track, the next loaded car or truck
is allowed to roll thereon. Immediately upon striking the tilting section of the
track the low body of the truck strikes the upwardly extending press lever L,
which passes beneath the bottom of said loaded car. Motion is at once communicated
through the press lever rod K to the oscillating T-lever J, which throws the
opposite arm outwardly beyond the rails E and causes the stop or hook ends h
of the opposite horns to spread and be thrown out of contact with the tread of the

page_text: forward wheels of the emptied or partly emptied car or truck. The emptied car
or truck being released immediately travels down the track to the point of connec-
tion with a return side track, so that the car may re-enter the mine. The
loaded truck by this time has passed over the elevated press lever L, and the
opposite horns are then free to be withdrawn against the sides of the rails under
the tension of the retractile withdrawing-springs-j', and this being done or effected
automatically before the forward wheels of the loaded car reach the ends of the
horns, the same are ready to check and hold the said car, while the same auto-
matically tilts the track and discharges its contents in the manner just described.
A curved friction bar M is secured to the rail-brace H adjacent to said press lever,
and is steadied by and works through the guide plate m, secured to one of the
central longitudinal timbers comprising the track frame. Directly below said
guide-plate in and to said timber, which may be designated
as A¹, secured the
stationary brake-plate N, over the face of which one side of the flat curved bar M
works. Pivoted at its inner end to said timber N' is the horizontal brake-lever O,
provided with an arm o, carrying a flat brake-shoe o¹, pivoted to said arm and
parallel with the stationary brake-plate M. As said lever is operated the brake-
shoe o' can be clamped upon the friction bar M as tightly as desired, and thus
prevents the tilting section of the track from tilting too suddenly or abruptly or
to return to its normal position with too great a jar. The outer end of the brake
lever extends to one side of the track and is connected with the hand operating.
lever P by means of the connecting rod p. The said hand-lever P is pivotally
mounted upon the adjacent frame-work and works between and is regulated by the
ordinary lever segments p'. While the car or truck upon the tilting section of the
track is discharging its contents the next succeeding loaded car is held in check
awaiting its turn by the supplemental safety check horns Q, pivotally secured to
opposite sides of the main portion of the track in rear of said tilting portions..
The said horns are also provided with the hook or stop ends 1 and are connected
together by the single intermediate retractile spring q', connecting said horns
together, so that the same may be normally held in contact with the rails or
drawn to the same after being released from their outspread positions.
Pivoted upon one side of the main portion of the track and to the supporting
timbers is a supplemental T shaped lever R, to the opposite ends of the head of
which are pivotally secured the opposite spreading-rods r, connected with the
opposite safety horns q, which when said T-lever R is operated will be spread
outward from the track and allow the loaded car to pass upon the tilting track when
the car in front of the same has been dumped or partly dumped of its contents.
The outer end of the operating arm or stem of the lever R is connected with the
hand operating lever S by means of the connecting rod s, and is controlled by the
operator in the same manner as the hand lever P, secured to the track-supporting..
frame to one side thereof. One of the spreading rods r is provided with a locking"
notch which when the horns are spread is designed to receive the inner end of the
latch T, pivoted to the inside of one of the rails B of the main portion of the track
and which serves to hold the horns apart until the loaded truck has passed beyond
the same. The other end of the pivoted latch is provided with an upwardly
extending strike-lug t, which when the rear wheels of the loaded wagon have passed
beyond the horns is designed to be pressed down by the flange of the front wheel.
The latch is of course immediately lifted out of the notch and allows the horns to
close and be ready to check the approaching car. The operation of dumping and
checking the loaded wagons is repeated and automatically controlled in the manner
herein described.
When it is designed to have one or more dumps in a single line of tracks-that
is, to partly dump the contents of one car at one point and then dump again at
another I provide a modification of the herein described apparatus, as illustrated
in Fig. 3 of the drawings. This figure illustrates the track as supported upon a
solid floor, through which the contents of the cars or trucks are dumped. In this
modification the T-shaped lever J is modified to form a cross shaped lever, to the

page_text: extreme upper end of which is pivotally secured a longitudinally sliding locking
bolt U, which by the same motion of the lever J that spread the horns I is thrown
into a suitable keeper in the frame or flooring, which thus holds the dump in a
rigid position, so as to carry any weight that may pass thereover. It will be
observed that when the horns are closed the bolt is withdrawn, thereby allowing
the next succeeding truck to dump. The controlling of the horns and locking bolt
is by means of the press lever V, corresponding to the press-lever F, and may be of
the same construction, but, as illustrated, is disposed to one side of the tilting track,
in order to insure a ready operation of the modified form of apparatus. The
construction, operation, and advantages of the dumping apparatus are now thought
to be apparent without further description.
In regard to the brake herein described it may be additionally noted at this point
that the same may not only be used for the purposes set forth, but may be also used
to regulate the motion of the dump and hold the same at any degree or pitch to
allow the contents of the car or truck to pass out quickly or moderately, as
desired.
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
