COMPLETE SPECIFICATION.
Improvements in Tipping-mechanism or Plant for Rail-road Trucks
or the like.
I, FRANZ NÜKEL, of Dortmund, in the Province of Westphalia, German Empire,
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: -
This invention relates to tipping-mechanism for rail-road trucks and the like
and has for its object various improvements in the construction of the same.
I have illustrated my invention in the accompanying drawing, in which
similar letters denote similar parts throughout the different views, and in which:
Figure 1 is an end-view of the tipping mechanism in a normal position,
previous to the tipping, and
Figure 2 a side-elevation of Figure 1, showing more clearly the driving-gear,
Figure 3 also an end-view, showing the position of the truck at the point where
the discharge fully commences.
My improved tipping mechanism is arranged for continued or uninterrupted
running, the said power being conveyed to the pulley h, actuating shaft g.
The general construction of such tipping plant being fully known, I think I
may abstain from describing such parts as do not refer to my invention and there-
for proceed to remark that in my improved tipping mechanism arranged, as here-
in before indicated for uninterrupted running, the tipping is effected by the aid
of two outer guide-rings a and a¹, or more precisely segments of the same, as
shown in the drawings.
•
As soon as the tipping mechanism is placed into gear with the power, the
smaller guide-ring a comes into contact with a larger driving pulley b,
Figures 1-3, and effects the movement along the path or distance yz, whereby
a rapid revolving of the tipping mechanism is effected.
Along the path or distance z,, however, the outer guide-ring segment a¹ comes
in contact with the pulley b, and by traveling along the said path ze effects a
slowing down or a reduction of the speed of the tipping mechanism, the said
pulley b also being actuated by the application of power.
Hereby it will be clear, that a slower emptying of the contents of the truck or
the like is brought about, and also a rapid return of the truck when emptied.
It will be seen, that I have attained, by the employment of two guide-ring
segments, as here illustrated, a tipping mechanism, in which the tipping is
effectually carried out, entirely by power, and in which a varying speed of rotation
is obtained.
In my improved construction, however, as herein before indicated, I employ
two power-conveying pulleys and b', the diameter of which varies considerably,
said pulleys being fixed to the main shaft.
Also, as herein before indicated, each pulley comes into operation at a different
time, so that the tipping-plant or mechanism is never, as it were, left to itself,
or to perform a movement of itself by the force of gravity or the like, but must

page_text: always move in the manner in which the same is actuated by the machinery or
power, this, however, being possible in my improved construction at a varying
speed.
When it was first tried to actuate tipping plant by machinery, it was found
that the tipping was effected too slowly.
After this it was tried to effect only a part of the movement by machinery or
more precisely to give back part of the necessary movement to the workmen.
This also was found unsatisfactory, for the reason that the desired variations in
speed were not produced with sufficient reliability.
In my improved construction, however, these difficulties have been overcome in
that firstly, by means of the same a rapid tipping of the truck or the like takes
place, until the point is reached, at which the effective discharge of the contents
of the truck fully commences, whereupon from the said point, where the tipping
commences, to the point, where the contents of the truck have been fully dis-
charged, or more precisely during the time which the segment al travels along
the path or way zx, a retarding of the speed is effected, and thus a slower rotation
or revolving of the tipping mechanism brought about.
As indicated, I abstain from further description of the plant, otherwise than to
the extent to which the same applies to my invention.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
A tipping mechanism or plant for emptying railway trucks or the like,
characterised by the said mechanism or plant being arranged so as to tip the truck
or the like at varying speeds by the employment of driving pulleys and b₁ of
largely varying diameter, said driving pulleys, conveying motion to the tipping
plant or mechanism; by means of two segments a and a¹ of correspondingly differ-
ing diameter, substantially as described.
