page_text: I ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Engineer, do hereby declare the nature of this invention (a communication from
Gottlob Warttinger Engineer and Gustav Rosenberg Architect both of Berlin in
the German Empire) 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 trolleys to be used for the
unloading of ships, in the deepening of water-courses or sinking of pits for the
loading of railway trucks and generally where loads are to be hoisted and
transferred.
In the accompanying drawings is as an example represented the application of
these improved dumping trolleys to an inclined loading apparatus provided with
two lines of rails.
In Figure 1 a dumping trolley is represented in two different positions i.e.
I while being drawn up the inclined plane.
II while being dumped automatically.
Figure 2 represents the dumping mechanism on a larger scale.
Figure 3 a side elevation of a box trolley and
Figure 4 a section of the same.
Figure 5 represents a plan of the trolley and Figure 6 a plan of the under frame
thereof.
The trolley is drawn up the incline by means of a rope B running over rope
pulleys F and runs down in consequence of its own weight. On their highest point
the inclined rails A suddenly turn downwards and end in an upwardly turned
curve i having the same radius as the wheels of the trolley.
The underframe of the trolley runs on two axles and four wheels and on it
rests the box of the trolley with 3 fixed sides. The fourth or front side e can be
lifted and is fastened to the box by the latches K K which engage with the pins 8 s
of the front side e.
The box is only connected with the frame by two plummer blocks at the front
axle in such a manner that the box turns round this axle. The latches K K are
connected in front by a rod and each is provided with a hoop or stirrup K¹ on the
part against the side of the box. As soon as these hoops K¹ run over the rollers o
of the curves the latches are lifted and the front side è is detached from the box.
The latches are elongated and joined by a rod in front to prevent the swaying of
the front side e.
In Figure 3 the door e is shown fastened down by the latches K; in Figure 1 (II)
the door e is shown held open by the latches K.

page_text: If trolleys with low boxes are used, as represented in Figure 2, the front side can
be dispensed with altogether.
The back end of the box is provided with a bearing bracket L on each side but
inside the trolley frame situated shortly before but a little lower than the hind
axle, which carry the shaft w.
By this shaft w the trolley is held and the box dumped on the trolley reaching
the downwards extending curve of the rails and the load of the trolley is emptied
automatically the front side e of the box being detached at this point.
In a suitable position underneath the dumping point a horizontal shaft v is fixed
which is provided with two levers H whose ends are claw shaped. These levers H
pass between the rails and are adjusted by the mechanism C so that the claws are
exactly at the same height as the shaft w of the trolley.
°
As soon as the claws of the levers H pass round the shaft w the levers H will be
carried upwards by the movement of the trolley and as these levers H turn round
the shaft they lift the back. end of the trolley box while the wheels of the under
frame remain on the rails. To the same shaft v, to which the claw levers H are
fastened, another lever h is fixed by which the trolley is drawn back on to the
inclined rails A through the reverse movement of the levers H when the box will
fall back on to the under-frame, the front side e will again be fastened to the box
and the trolley will run down the incline in consequence of its own weight drawing
the rope B after it. The levers H elevated during the dumping fall on to india
rubber buffers to lessen the shock in the righting of the trolley.
These rubber buffers may be carried upon a movable beam or block M Figure 2
whose position may be regulated by the screw / so that by turning this screw the
block M is moved up or down as required and the height of the claws of the levers H
may be adjusted so as to correspond with the height of the axle w.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent I declare that what I claim is
1. In dumping trolleys the arrangement of the latches K which are automatically
lifted by their hoops or stirrups K' by means of the rollers o or other equivalent
means for the purpose of unfastening the front side e of the trolley box substantially
as specified.
2. In dumping trolleys the connection of the trolley box with the under frame
in such a manner that the box turns round the front axle of the under frame
substantially as and for the purpose specified.
3. In connection with dumping trolleys the combination with the levers H
(having claw-shaped ends which engage with a shaft w suitably placed on the box
of the trolley) fastened to a shaft v supported in the fixed framing for the purpose
of holding and dumping the said box to empty its contents, of another lever h
fixed to the said shaft v for the purpose of returning the trolley substantially as
specified.
4. In dumping trolleys a mechanism for adjusting the claw levers H to keep them
always at the same height with the shaft w of the trolley, substantially such as
specified.
5. In dumping trolleys the elongation of the latches K to prevent the swinging
of the front side e of the trolley box when the latter is being dumped, substantially
as specified.
