Improvements in or relating to Apparatus for Emptying Pit Tubs,
Corves, and the like.
We, HENRY FISHER, Colliery Manager, THOMAS GODFREY LEES, Colliery
Manager's Assistant, and EDWARD Ross, Enginewright, all of Clifton Colliery in
the Borough of Nottingham, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in what are known as kickups or tipplers
for emptying pit tubs, corves, and the like, and to apparatus connected therewith.
Heretofore tipplers as commonly used at coal and other mines and works for
emptying wagons, tubs and the like have been constructed with a counterbalancing
weight, in some cases consisting of a vessel containing liquid, so as to cause the
tippler to right itself automatically, that is to return the tippler to its normal
position after the loaded wagon has emptied itself so that it can be removed and be
replaced by a loaded one.
In carrying out this invention we preferably construct the tippler in duplicate, the
duplicate parts being preferably placed diametrically opposite each other and both
carried on one shaft placed between them and journaled and turning freely in
suitable bearings. One part of the tippler will thus balance its counterpart in all
positions, but when in a vertical position and a loaded wagon or tub is put in the
upper part of the tippler the loaded wagon or tub will cause it to turn over and it
will make half a revolution, empty the wagon or tub, and bring the lower part to
the upper position which in turn receives a loaded wagon or tub which simultaneously
empties itself and brings the lower part containing the previously emptied tub to the
upper position; this is removed and replaced by a full one and the operation
repeated continuously.
By this means two loaded wagons or tubs are inverted and emptied each revolution
of the tippler and a greater number of wagons can thus be emptied in a given
time than by existing forms of tipplers which have to be overturned to empty the
contents of a loaded wagon or tub and then returned to their first position so that
the empty wagon can be removed and replaced by a full one.
It is obvious that in some cases the tipplers may be made in triplicate or a great
number of parts and in that case would empty three or more wagons or tubs at one
revolution.
The tippler shaft may be provided with a brake wheel so that it may be stopped
or regulated as required, and provision may also be made for holding the tippler in
position while the wagons are run on and off; this may be effected by a catch
engaging with a wheel on the shaft or other appliance and such catch or appliance
may be adapted to be disengaged by the loaded wagons as they are run on, or by the
attendant.
In connection with tipplers used for emptying coal wagons or tubs or wagons
containing minerals which it is not desirable to further break up, we form the
upper end of the shoot in transverse segments of convenient lengths arranged
preferably so that their inner surfaces form a curve approximating to that described
by the tippler; these segments are carried by adjustable levers so that the distance
of the segments from the tippler may be adjusted. The levers are operated by
counterbalancing weights so as to cause then to..approach the tippler when they
carry no load. In some cases the segments may be carried by chains or ropes
passing over pulleys provided with weights; when the tippler turns over, the
segments of the shoot are close to the top of the wagon or tub and the mineral
consequently does not fall on to the shoot but is retained in the wagon by the shoot

page_text: till the wagon or tub is nearly inverted and the whole weight of the mineral over-
comes the counterbalance weights and causes the segments of the shoot to recede
from the tub and permits of its free passage down the shoot. By this means the
breakage for example in the case of coal is minimised and there is a consequent less
production of small coal.

Improvements in or relating to Apparatus for Emptying Pit Tubs,
Corves, and the like.
We, HENRY FISHER, Colliery Manager, THOMAS GODFREY LEES, Colliery
Manager's Assistant, and EDWARD Ross, Enginewright, all of Clifton Colliery, in
the Borough of Nottingham, 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 improvements in what are known as kickups or tipplers
for emptying pit tubs, corves, and the like and to apparatus connected therewith.
It will be best understood by reference to the accompanying drawings in which
Fig. is a plan of tippler and shoot, Fig. 2 is a front elevation of tippler and shoot,
shewing a loaded tub in the upper part ready to be overturned and an empty tub in
the lower part, Fig. 3 is a side elevation of part of Fig. 2.
Heretofore tipplers as commonly used at coal and other mines and works for
emptying wagons, tubs, and the like have been constructed with a counterbalancing
weight in some cases consisting of a vessel containing liquid, so as to cause the
tippler to right itself automatically, that is to return the tippler to its normal
position after the loaded wagon has emptied itself, so that it can be removed and be
replaced by a loaded one.
In carrying out this invention we preferably construct the tippler with a part A
shown in its upper position and a part B which is a duplicate of the part A, and is
shown in its lower position, the parts A and B are preferably placed diametrically
opposite cach other and are both carried by the central shaft C journaled in
bearings C¹.
It will thus be seen that the duplicate parts A and B of the tippler will balance
each other in all positions but when a loaded tub shown at D is run on the part A it
will by its own weight turn the tippler over, empty itself and bring the part B
together with the inverted tub shown at E into the upper position, this process is
constantly repeated by replacing the empty tub which has now returned to the
upper position by a loaded one.
By this means two loaded tubs or wagons are inverted and emptied each revolution
of the tippler and a greater number of tubs can thus be emptied in a given time
than by existing forms of tipplers which have to be overturned to empty the contents
of a loaded tub or wagon and then returned to their first position so that the empty
tub can be removed and replaced by a full one.
It is obvious that in some cases the tippler may with advantage be made in
triplicate or a greater number of parts in which case the parts would be equally
distributed so as to counterbalance each other and would empty three or more tubs
or wagons at each revolution.
The tippler shaft C is provided with a brake wheel F fitted with a band For
other arrangement, for holding the tippler in position while the empty tubs are run
off and the loaded ones run on, the brake band F' is actuated by a lever G pivoted
at G which automatically applies the brake by the action of the weight G on its
outer end the outer end of the lever G is raised to release the brake by a lever H.

lever J pivoted at and provided with a step K for the foot of the attendant.
a
In connection with tipplers used for emptying coal tubs or wagons, or tubs
containing mineral which it is not desirable to further break up, we form the upper
end of the shoot in transverse segments of convenient lengths arranged so that their
inner surfaces form a curve approximating to that described by the tippler. The
upper end of the shoot as shown in the drawings is formed by segments L and M
the former being carried by the shaft P and the latter by the shaft R both shafts
being journaled in suitable bearings, the segment L is counterweighted by
weight on the lever O and the segment M by a weight Q' secured to the chain Q
passing over the pulley Q and secured to the segment M at Q3, by the action of
these counterweights the segments L. M. of the shoot will take the position shown
by dotted lines at L' and M when they carry no load. When the tippler is over-
turned the segments L and M will break the fall of the load which will overcome
the action of the counterbalancing weights P and Q' and cause the segments
to recede from the tippler and permit of the passage of the mineral down the
shoot.
By this means the breakage for example in the case of coal is minimised and there
is consequently a less production of small coal.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. Arevolving tippler adapted to receive two or more tubs and which simultaneously
inverts a loaded tub and returns an inverted empty tub to its position for removal
substantially as specified.
2. A revolving tippler formed of two or more tub receiving parts such as A and B
substantially as described and illustrated in tlie accompanying drawings.
3. A tippler in which a tub receiving part such as A is counterbalanced by a
corresponding part B substantially as described and illustrated in the accompanying
drawings.
4. The combination with a tippler of a shoot formed of counterweighted segments
such as L. M. for preventing breakage of the material substantially as described and
illustrated in the accompanying drawings.
5. The combination and arrangement of parts constituting the complete tippler
substantially as described and illustrated in the accompanying drawings.
