Improvements in or relating to Coaling Stations or Depots.
A communication from FRIEDRICH CORRELL, Civil Engineer, of Neustadt
a/Haardt, in the Kingdom of Bavaria.,
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of London,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The ordinary coaling stations of a railway suffer from the drawback that a trans-
fer of coal from the several store places to the place of delivery, and vice versa is
not conveniently possible, and that, on the contrary the coal can only be passed
from the coal reservoirs to the place of delivery which also is the place of intake
to the coal reservoirs, while the transfer to the place of storage by machinery as
well as the employment, necessary under all conditions, of the plant, kept at the
station, for the purpose of equalising the weekly and monthly variations by means
of the mechanical contrivances, used for the transfer of the coal to the coal
reservoirs, was not possible.
According to the present invention the coal reservoir or reservoirs by which
is to be understood the compartments from which the coal is loaded into the
trucks etc., are so combined with an elevator device, that it is not only possible
to transfer the coal from the reservoirs to the trucks or wagons, and vice versa,
from the trucks to the reservoirs, but also, by means of the same mechanical
iransfer device to transfer the coal from the place where it is delivered to the
storage depots and from thence to the reservoirs, or direct to the receiving place.
This object is obtained, according to the present invention, by an arrangement
according to which the coal reservoir together with its transfer or conveying
device is placed between the storage depots and the loading or delivery point
which also serves as the receiving place, while a longitudinal passage, through
which the conveyor in the form of a bucket chain or equivalent passes, is con-
nected on the one hand by means of shoots with the storage depots and, on the
other hand with the delivery station. The coal reservoir or reservoirs can be
connected by passages constructed as required both with the depots and with the
delivery station.
In one arrangement according to the present invention it is possible to discharge
the ashes simultaneously with the delivery of coal, so that not only a few trains
but each separate truck or locomotive which takes in coal may also at the same
time deliver its ashes.
In the accompanying drawings a coaling depot of the improved type is
represented.

page_text: In the drawings A represents the coal store the contents of which are intended
to meet special requirements or demands, such as in cases of war, strikes, or
for equalisation of changes, or to meet unexpected large demands..
B represents the rails, on which the trucks travel, at the coal discharging or
receiving point, and according to the present invention the problem to be solved
is that coal may be transferred from B to A, as well as from A to B according
to requirements. For this purpose between A and B a coal reservoir H com-
prising one or more divisions is arranged, beneath which a longitudinal passage E
is provided, below the normal level of the rails, whilst the coal reservoir is suffi-
ciently high for the purpose of transferring the coal from it either to the coal
depot A or to B by means of shoots L and I or other means of delivery.
"
The storage depot A is connected with the longitudinal passage E by narrow
pockets" or chambers M while the place of delivery or in-take is connected
with the same passage E by "pockets" or chambers B and incline shoots D).
Within this longitudinal passage is arranged the elevator chain F comprising a
series of pivotted buckets or any other suitable transport device, passing up
through a vertical shaft to the coal reservoir H in such manner that the coal dis-
charged into the passage E falls into the buckets of the elevator chain or trans-
port device and will be delivered to the coal reservoir H.
It will readily be understood that by opening the necessary valves or doors in
the shoots of the storage depot and closing the connections with the delivery
depot, coal may be taken off from any part of the storage depot passing through
the shoots to the chain, and thence taken to the coal reservoir. It will also be
readily understood that coal delivered at the point 13 may be transferred, after
opening the valves or doors in the shoots connected with the passage E to the
coal reservoir H..
It will further be readily understood that the coal can be transferred both to
the place of delivery for the purpose of charging trucks, wagons or locomotives
by means of the shoot I, or to the storage depots by means of the shoots L.
From this it follows that it is possible to transfer the coal from any place in the
depots A to the delivery place B, for it is only necessary to open the corresponding
pocket or chamber M from which the coals are taken, as described, to the reser-
voir H from which they pass directly by means of a shoot I to the trucks on
rails B.
Figure 4 represents a modification in the arrangement of a coaling station.
differing from the one just described, in that the coal reservoir H is arranged
over a greater number of rails. In this manner it is possible to load not only the
wagons standing at the place of delivery B, but also those on the rails BB,
with coal from the reservoir H H; only the first rail B being provided with a
chamber in communication with the passage E. Beneath the other
rails are provided passages which communicate with another horizontal
passage E, which runs underneath all the rails and is provided with another
bucket-chain F, for the purpose of taking off the ashes etc. and transferring them
to the reservoir X serving as a reservoir for such material.
It is obvious, that in the arrangement as illustrated, each truck or locomotive
standing on the rails BB can not only be charged with coal, but may also,
transfer its contents of ashes etc. to the bucket chain Fl from which they are
carried to the reservoir X.
It is also possible to employ a bucket-chain or conveyor in the passage E¹ to
receive the coal from a number of trucks at the same time and convey it to the
reservoirs or to the storage depots and vice versa in the manner described..
In very large coaling stations the coal elevator bucket-chain F may be divided
into two parts, as represented in Figure 5. By means of this arrangement, for
instance, the one bucket-chain may work over the coal reservoir H, while the
other, at the same time will transfer the coal to the coal depots, or also, through
the, shoots L, and inclined shoots I, directly to the tenders of the locomotives or
trucks standing on the rails B.

page_text: Suitable mechanism will of course be provided for working the bucket-chains
or conveyors, and for operating the various shoots, valves, doors and the like.
Having now particularly described and ascertained the nature of the said in-
vention as communicated to me by my foreign correspondent, and in what manner
the same is to be performed I declare that what I claim is:-
1. A coaling station in which the transfer of coal from the place of delivery
to the coal storage depot and rice versa, is effected by arranging a coal supply
reservoir, such as H. between the storage depot and the place of delivery and a
bucket chain or equivalent for transferring the coal to the supply reservoir
arranged in a longitudinal passage such as E, communicating with the place
of delivery and with the storage depot by suitable passages, whereby the coal
may be transferred both from the storage depot (A) as well as from the place of
delivery (B) to the supply reservoir above, or by the same means from the storage
depot to the place of delivery and rice versa substantially as described.
2. A coaling station of the kind described in which the supply reservoir
extends over several sets of rails, and the "pockets" of one or more sets of the
rails, communicating with the storage depot while beneath the other rails are
chambers communicating with a horizontal passage provided with conveyor
buckets for the transfer of ashes to an ash reservoir, by which means not only a
simultaneous taking in and delivery of coal is possible, but also a simultaneous
taking in of coal and delivery of ashes to and from several trucks may be accom-
plished, substantially as described.
3. A coaling station characterised by the combination of coal reservoirs such
as H with a coal depot such as A a longitudinal passage such E, and "pockets"
such as M substantially as described.
4. The complete coal station substantially as described and illustrated in
Figures 1, 2 and 3 or in Figure 4 or in Figure 5 of the accompanying drawings.
Dated this 30th day of March 1899.
