Foreign Patent Solicitors 6, Lord Street, Liverpool and 6, Bank Street,
Manchester both in the County of Lancaster & 323 High Holborn in the County
of Middlesex, Civil Engineer, do hereby declare the nature of this invention
to be as follows:-
The tipping apparatus employed in mines for throwing out the products obtained
are operated either by hand or mechanically; these latter may be divided into
tips with equal and tips with unequal circumferential speed. The unequal circum-
ferential speed is preferable as it allows a slower tipping and a speedier return to
an upright position of the tip wagon; by this means, on the one hand, an even
feeding of the dressing apparatus, lying beneath the tip, is obtained, and on the
other hand, by the speedy return of the tip wagon, a frequent utilization of the
tip, indispensably necessary for the working, is attained.
This improved tip fulfils these conditions.
On the accompanying drawings
Figure 1 shows the tipping apparatus with a wagon reversed,

Figure 4 is a section of the breaking device of the tipper.
As soon as a wagon is pushed onto the tip, the lever a, with the small roller b
attached thereto, is drawn out in the direction of the arrow Figure 3 by the
workman attending to the wagon; by this movement the coupling device c is
pressed into the constantly rotating belt pulley d, and sets the shaft e, with the
rollers situated thereon, in motion.
The tipping frame g, which rests on the four rollers and fif, is then, through
the friction, slowly moved in the direction of the arrow y until the wagon is tipped,
the roller bon the hand lever comes simultaneously in front of the angle iron h
attached to the frame of the tip, as shown in Figure and holds the coupling
device in its advanced position until the slot i ati, Figure 2, is reached.
As soon as the roller & drops into the slot at , the weight k, (Figures 2 and 3)
attached to the lever, comes into play and disconnects the coupling. The roller b
of the hand lever a then passes back again behind the angle iron and makes way
for the quick backward motion which now commences.
This motion is automatic,
and is brought about in the following manner through the excess weight of the
tipping frame and wagon.
The centre of gravity of the tipping frame and wagon is situated between the
middle of the tip and the point i, Figure 1. In consequence of the action of
the weight o, the lever n, already brought into tension in the last stages of the slow
movement of the tip, presses against the pin m situated on the frame of the tip, and
gives the impetus for the return motion; when this impulse is given, the tip frame
and wagon rolls, in consequence of the proportions of the centre of gravity above
named, in the direction of the arrow Figure 1 on the now free running shaft e by
the rollers ff and on the other two carrying rollers "back into the position
shown in Figure 2. The pins p p', Figure 1, serve for limiting the lift of the three
armed lever n. In order to guard against an overdriving of the tip, a brake is
employed, as shown in Figure 4, which operates by the brake piece q which is

The tipping apparatus may also be employed, by maintaining. the direction of
rotation of the arrow y 'Figure 2, that is to say that no return motion takes place,
in such a case an apparatus such as shown in Figure V, or the like must be made
use of, so that the weight of the hand lever a¹ presses, by means of a suitable
connection, against a brake block gliby means of a brake check attached to the
lever a. The moving backwards of the tipping apparatus is prevented by means of
the bolt R, Figures 1 and 2 which drops in when in a normal position.

Improvements in Tipping Apparatus for Tipping Wagons
and the like.
A communication by ULLRICH FRANTZ, of Zabrze on the Saale, in the Empire
of Germany, Engineer.
I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6, Bank Street, Man-
chester, both in the County of Lancaster, and 323 High Holborn in the County of
Middlesex, Civil 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:-
The tipping apparatus employed in mines for throwing out the products obtained
are operated either by hand or mechanically; these latter may be divided into tips
with equal and tips with unequal circumferential speed. The unequal circum-
ferential speed is preferable as it allows a slow tipping and an accelerated return to
an upright position of the tip wagon; by this means, on the one hand, an even
feeding of the dressing apparatus, lying beneath the tip, is obtained, and, on the
other hand, the accelerated return of the tip wagon, enables a more frequent
utilisation of the tip.
These objects are attained by the device forming the object of the present
invention in the manner hereafter described.
On the accompanying drawings-
Figure 1 shows the tipping apparatus with a wagon in its upright position,
Figure 2 the same with the wagon reversed,
Figure 3 a longitudinal section of Figure 1,
Figure 4 is a sectional view showing the braking device of the tipper,
Figure is a side view of a modified form of brake for a tipper designed to
rotate in one direction only,
Figure 6 a side view showing means for arresting the tipper in its proper
position.
As soon as a wagon is pushed onto the tip, the lever a, with the small roller b
attached thereto, is drawn out in the direction of the arrow, Figure 3, by ithe
workman attending to the wagon; by this movement the coupling disc cris,shifted
into contact with the constantly rotating belt pulley d and sets the shaft,e with.the
rollers situated thereon, in motion.
The tipping frame g, which runs on the four rollers mounted on shaft e
and on a similar shaft e', is then slowly moved by the driving rolls ffin the
direction of the arrow y, Figure 1, until the wagon is turned over, the roller bion
the hand lever a running on the front surface of the angle iron attached to the
frame of the tip, as shown in Figures 3 and 5, and thus holding the coupling.disc c
engaged with pulley d. This position remains until the slot has arrived at the
point, Figure 2.

page_text: As soon as this has taken place, the roller b drops into the slot at under the
influence of the weight k, Figures 1 and 3, attached to a lever arm of the shifting
fork of the dise c, said weight simultaneously disconnecting the coupling. The
roller of the hand lever a does not however remain in the slot but passes right
through it and out at the back of the angle iron and makes way for the quick
backward motion of the tipping apparatus which now commences. This return
movement is automatic, and is brought about by the action of gravity in the
following manner-
The centre of gravity of the tipping frame and wagon lies above the centre of the
tip in the line 1, Figure 2, so that it will be evident that the tip, when once started,
will run back by its own weight. This start is effected by the weight o mounted on
the lever n having already been lifted a certain distance by the pin m of the tipping
frame during the last stages of the slow movement of the tip. As soon therefore
as the coupling has been shifted and the apparatus stopped the weight o presses
against the pin m and gives the impetus for the return notion; when this impulse
is given, the tip frame and wagon roll by gravity in the direction of the arrow,
Figure 2, on the rolls ff of the now free running shaft e and on the other two
carrying rollers back into the position shown in Figure 1. The pins p p³,
Figure 2, serve for limiting the lift of the three armed lever n.
In order to prevent
overdriving the tip, a brake is, employed, as shown in Figure 4, consisting of a
wedge 7 mounted on the tip frame, Figures 2 and 4, and a pin s, which is connected
with the tip frame, being inserted under lever armt mounted underneath the tip
frame. The lever arm has braking cheeks which are loaded with a weight r, said
lever being limited in its downward movement by the pin s. On the frame
approaching the limit of its rotation the wedge 9 runs under the weighted lever t
thus braking and finally stopping the frame.
q
The tipping apparatus may also be made to rotate in the direction of the arrow y
only, Figure 1, that is to say the reversal need not necessarily take place, in such
case an apparatus such as shown in Figure 5, or the like, must be made use of, the
weight acting to press the brake cheek w of the hand lever a against a brake
block of the rotating frame. The backward movement of the tipping apparatus
is prevented by means of a stopping device, the operation of which may be as
follows-
A lever His arranged on the extended shaft G, Figures 1 and 6, which, when
the tipper is set in action, withdraws the bolt F in the direction of the arrow K
from the frame of the tipper and causes it to pass in front of the inclined cam L.
The frame of the tipper is thereby set free to revolve. As soon as the lever H,
when the wagon is emptied, moves in the direction of the arrow M, which it will do
on the coupling being shifted by the action of the weight K, the bolt F follows its
movement, being shifted by the angle lever N' engaging with the bolt Factuated
by its weight N. The said bolt is thus caused to come into contact with the surface
of the rotating tip frame before the end position is reached, the bolt will come in
contact with the inclined surface of the cam Lacting as a brake and finally entering
between the end of the cam L and the stop and arresting the tipper frame. On
the other side of the tipper there is a stop P, Figure 4, attached to the frame which,
when the end position is reached, comes gently in contact owing to the braking
influence of cam L with a rest Q screwed down on the support beam.
The final position of the tipper is thus fixed by means of the cam L and the
catch and the bolt apparatus H J N N in connection with these parts, or by
means of the stops P and Q.
Having now particularly described and ascertained the nature of the said inven-
tion 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-
In tipping apparatus with a mechanical discharge operated by means of friction
rollers -
1. A device for automatically returning the tipping apparatus consisting of a

page_text: .
lever n held stationary by means of an upper peg p until a pin m on the tipping
apparatus moves the lever in the direction of the lower peg p' and a weight o
commences the return movement, at the same moment in combination with a hand
lever a, the roller of which passes through a slot i behind the flange h and
disengages the coupling c d.
2. In combination with the device described in Claim 1, a brake consisting of a
wedge q, Figure 4, attached to the tipping apparatus which wedge, on the return
of the apparatus before the end position is reached, can push itself under a brake
check which is loaded with a weight r.
3. The device for fixing the end position of the tipping apparatus and at the same
time for braking it before the end position is reached, consisting of a bolt
apparatus HJ N N', Figure 6, connected with the shaft G in combination with
the sloping cam L attached to the frame of the tipping apparatus and the rest O,
as well as the stopping device, in combination with the last named arrangement,
formed of the stop P on the frame of the tipping apparatus and the contact
piece Q, Figure 6, attached to the support beam substantially as hereinbefore
described.
