Improvements in or relating to Means for Tilting Trucks or the like
for Automatically Unloading the same.
I, WILHELM ELLINGEN, of 8, Metzerstrasse, Cologne, Engineer, 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:
In the annexed drawing Figs. 1 to 5 represent various forms of this invention and
Fig. 6 is a detail view of part of the construction.
This improved arrangement consists essentially of an oblique truck framing a
and of an inclined track which may be wholly or partly curved on the vertical
plane.
The truck framing a is provided with a horizontal platform 6 for receiving the
trucks to be emptied and can be moved on an oblique track c upwards or down-
wards or upwards and downwards.
It is generally provided with running wheels, but it can be constructed as a slid-
ing carriage.
The running track forms in the vertical plane such an inclination that the
horizontal platform b of the carriage framing running on the track gradually tilts
upwards as in Fig. 1, when the arrangement is used for lifting the carriages or
trucks downwards as in Fig. 2, when the arrangement is intended for letting the
cars or trucks down.
The running track can also be vertically curved as shown in Figs. 3 & 4. The
track c of the car framing a can also lie over the platform b, that is to say the plat-
form can be suspended as shown in Fig. 5.
The latter arrangement will be preferable, when for special reasons it is not
desirable to sink into the ground with the car framing. Of course the track e can
also have any desired inclination other than that indicated in Fig. 1 and that in
Fig. 5. It is essential, that the car to be emptied keeps a certain position until it
is immediately emptied. An important element of the car a is the drawing rods d
with the cross head e.
On a transversal axle f of the under car there are seated laterally on the outside
two strong drawing rods which end on the top in the common cross head 6.
The cross head is provided at each exterior end with an axle which carry rollers,
which operate between guiding rails g. On the thus guided cross head a rope chain
or the like of a winch is fixed.
This fastening however is effected conveniently by inserting a pulley i with
fork and spindle k and buffer spring 1. In this arrangement the rope forms a loop,
and can consequently be thinner and a winch of smaller drum diameter but of
greater velocity can be used which is important when working with an electro
motor. A complete system of block and pulley tackle can be inserted between
cross head and winch when for instance the winch is driven by human power.
The buffer spring renders, the start elastic. To guard against back running of the
car framing for instance should the rope break, the cross head is provided at the

page_text: end with two turnable arms m which are fixedly keyed on an axle n seated on the
cross head. On the axle there is in the middle the lever o, the fork like end of
which seizes the pin of a collar of the spindle k in such a manner, that by the pull
on the drawing rope s the spring is compressed and the arms m are lifted up and
are released from the ratchet upon which they operate. Should however the rope s
break the pull of the rope of course ceases, the spring presses the spindle k
back into its lowest position and the arms m engage with the ratchet. The cross
head e is seated at such distance, that is to say the drawing rods d are so long and
also arranged so far from one another, that the carriage or truck h can move easily
forwards.
In certain cases for instance when the truck is not moved forwards, but back-
wards as also in the arrangement with hanging track, Fig. 5, the drawing rods.
with cross, head e (Fig. 1) are superfluous and the rope can be fixed directly on the
carriage framing in the manner shown in Fig. 6.
The cars can be tilted and emptied forwards or sidewards. The platform can also
be constructed for receiving several trucks, also for receiving simultaneously two
and more trucks emptying forwards, or for emptying sidewards or. with one
carriage emptying sideways and one for emptying forwards. The whole arrange-
ment can also be constructed in a transportable manner.
The truck framing a with the trucks thereon, loaded with coal, ore or other
material is raised on the oblique track or lowered by means of a winch having a
rope or chain,, as indicated in Figs. 1 & 2. In the arrangement shown in Fig. 1
the winch requires a driving motor of any kind, but in Fig. 2 the necessary winch
need only to be provided with brakes and does therefore not require any driving.
power. Of course a counter weight must then operate opposed to the weight on
the winding drum or also directly on the truck traming in order to facilitate the
raising or lowering of the truck. The counter weight will preferably be variable
during the lifting. Such a counter weight q can also be applied when lifting the
car to be emptied, as shown in Fig. 1. The counterweight is however dispensed
with when two apparatus are combined and are operated by a single or two coupled
winches in such a manner that the one car is raised when the other. one goes
downwards.
When several single or double arrangements are standing close together they
can be operated conveniently from a common transmission, which is very practical
with the kind of the winches in view. The winch is constructed in such a manner,
that the drum is operated by a friction coupling of the communicator which is
effected when pulling the load high. The back movement of the under car and the
framing with empty trucks is however effected when the coupling is disengaged
and by operating vigorous band brakes for regulating the velocity. A second safety
brake is in connection with a conical pendulum in such a manner that at a more
than normal velocity this brake is automatically operated. The motor and the
communicator shaft run always in the same direction without being reversed. The
car h is secured on the under car framing by known means against undesired.
rolling. off or tilting. In Fig. 1 there are arranged brake blocks of
large dimensions turnable simply horizontally and adjustable by
of a
means
screw spindle the car can also be held in such a manner that "the axles
are grasped by drawing rods turnable from below upwards with hooks as is very
usual. With regard to the position of the winch it need not be necessarily in
the, position indicated in Fig. 1.
By guiding the rope at the top first over a roller Fig. 2 the winch can be placed
at any desired convenient place. When working the apparatus by hand it will
even be useful to arrange the hand cable winch on the car framing a. The work-
men operating the winches can then go up or down and can open the fastenings
of the truck immediately before unloading the same.
The winch for hand or motor operation standing on the platform of the car
framing, can also be rendered inoperative in a simple manner, say by a toothed wheel
being engaged in a toothed rod of the track.

page_text: Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. A truck framing a running on rails and constructed obliquely with plat-
form b for receiving cars of any kind for the purpose of lifting and lowering the
same on an inclined or vaulted track, so that the bottom of the truck takes succes-
sively such an inclined position, that the contents can be emptied automatically.
2. An inclined track curved wholly or partly in the vertical plain in a form
required by the construction of the truck framing and its manner of operation.
3. In the framing as under Claim 1 the arrangement of a drawing rods d with
guided cross head e, whereby the bow d is turnable round an axle f of the car fram-
ing and formed in such a manner that the truck can move forwards with the under
carriage.
