Improvements in or connected with Storage Buildings for Coal and
other Materials:.
We THOMAS WRIGLEY of Waterside House, Todmorden in the County of
York, Mill Manager, and Toч TAYLOR of 31 Royal Exchange, Manchester in
be County of Lancaster, Engineer do hereby declare the nature of this invention
to be as follows:-
Our invention relates to buildings for storing coal or other material of a
powdered, granular or pebbly kind and consists in an improved construction or
arrangement of said buildings and of the means for discharging or removing the
coal or other material from the same.
In the coal storage buildings hitherto erected, the coal deposited or stocked in
the same by means of elevators, tips or other appliances has been discharged or
taken out from the top of the coal at the top or side of the building. This practice
has the disadvantage that the coal first stocked is last used and that in order to
use up the coal first stocked the storage building must be completely emptied out,
so that additional buildings are required to stock a further supply of coal, as other-
wise the coal in the lower part cannot be used up and will deteriorate. The
object of our improvements is to obviate these defects by so constructing the
building and coal discharging appliances that the coal is taken out from the bottom
of the stack or building and the coal first put in is also first used, and that fresh
coal can be put into the storage building at the top while the old coal is removed
from below, and the storage buildings.can be made of less capacity for a certain
consumption.
In carrying our improvements into effect, we arrange the building and appliances
somewhat as follows: Upon the bottom floor of the building we arrange a series of
parallel conveyors at convenient distances from each other extending from front
to back, which discharge their contents into another conveyor placed across the
ends of the former, this conveyor delivering the coal as may be required by the
local circumstances into an elevator or other conveyance for delivery to the boiler-
house or other place of consumption.
Along the sides of the parallel conveyors we erect walls, columns or pillars of
convenient height, and cover in the space between the conveyors by means of brick
arches, flags or plates placed on girders or other means used for forming floors for
supporting heavy weights, so as to form a second or false floor in the building
containing openings above the conveyors. These openings or part of the same we
close by means of sliding doors operated by screw spindles or other convenient
neaus, the part between the doors being covered by plates or their equivalent.
The conveyors may be worm conveyors or any other suitable kind.
When any of the doors are opened, the coal above them drops into the conveyor
and is carried out of the building into or by the cross conveyor. By opening and
closing the doors more or less a regular abstraction of the coal all over the floor
space or if desired more from one part than another may be obtained. The
building is charged at the top by means, of elevators and conveyors in any usual
way with small coal as in the case of storage buildings hitherto used."

page_text: Obviously the same arrangement of false floor and conveyors can be used for
storage buildings for other materials than coal. The false floor may be on the
level of the surrounding ground or raised above the same.

Improvements in or connected with Storage Buildings for Coal and
other Materials.
We THOMAS WRIGLEY of Waterside House, Todmorden in the County of
York, Mill Manager and TOM TAYLOR of 31 Royal Exchange, Manchester in
the County of Lancaster, 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 buildings for storing coal or other material of a
powdered, granular or pebbly kind and consists in an improved construction or
arrangement of said buildings and of the means for discharging or removing the
coal or other material from'the'sanie.
In the coal storage buildings hitherto erected, the coal deposited or stored in tlie
same by means of elevators, tips or other appliances has been discharged or taken
out from the top of the coal at the top or side of the building. This practice has
the 'disadvantage that the coal first'stored is last used and that in order to use up
the coal first stored the storage building must be completely emptied out, so that
additional buildings are required' to store a further supply of coal, as otherwise the
coal in the lower part cannot be used up and' will deteriorate. The object of our
improvements is to obviate these defects by so constructing the building and coal
discharging appliances' that the coal is taken out from the bottom of the stack or
building and the coal first put in is also first' used, and that fresh coal can be pnt
into the storage building at the top while the old coal is removed from below and
the storage buildings can be made of less capacity for a certain rate of
consumption.
On the drawings 'appended hereunto a coal storage 'building constructed in
accordance with our invention is represented,
Fig. 1, showing a longitudinal and Fig. 2, a cross section of the same, and
Fig. 3, a discharging shoot and slide on an enlarged' scale.
On the drawings A represents the storage building, B a coal crushing machine
fed through a hopper b and delivering the crushed coal into an elevator C or more
than' one by which the coal is raised into the top conveyors D which deliver it into
the storage building, these arrangements not forming part of my invention:
In carrying out our improvements we arrange the bottom part of the building
and discharging apparatus preferably as follows: Upon the bottom floor of the
building we arrange a series of parallel conveyors E at convenient distances 'from
each other and extending from front to back, which discharge their contents' into
another conveyor F placed across the ends of the former, this conveyor delivering
the coal as may be required by 'the local circumstances into an elevator or other
conveyance for delivery to the boiler house or other place of consumption. In
case the coal is used for steam boilers the cross conveyor' is conveniently utilised
for delivering coal into the elevator or hoppers described in my Specification for
Letters Patent No. 15033 A.D. 1889:
On the drawing three longitudinal conveyors E are shewn, but obviously there
may be less or more of them according to the size of the storage building and there

page_text: may be one or more cross conveyors arranged under them inside the building as
well as outside thereof if desired or the cross conveyor may be omitted.
Along the sides of the conveyors E we erect columns G of convenient height, or
instead of the columns we may erect pillars or walls, and we cover in the space
between the conveyors E by means of brick arches H supported on girders g, or by
means of stone flags or plates placed on girders or by other means ordinarily used
for forming floors for supporting heavy weights, so as to form a second or false
floor in the building. The space between the columns or their equivalents is like-
wise covered in by troughs h as shewn or their equivalent, containing openings at
intervals to which shoots h' are fixed, so that the coal can drop through the shoots
into the conveyors. These shoots are so arranged that they can be closed by
sliding doors operated by means of screw spindles e engaging in nuts attached
to the doors, the screw spindles being supported in brackets d ' and fitted with
hand wheels e. According as the doors are opened or closed more or less, more
or less coal will be abstracted from the store and by regulating the opening of the
doors a regular abstraction of the coal all over the floor space, or if desired more
from one part than from another, may be obtained. Any other suitable arrange-
ment of doors or means for opening or closing them may be used.
The conveyors shewn on the drawings are worm conveyors, but any other
suitable kind, for instance chain and scraper conveyors, may be used, and they
may be driven by any suitable ordinary means.
The floor supporting the coal may be on the level of the surrounding ground or
raised above the same. Obviously instead of building a second floor, the ground
floor of the building may have pits sunk or formed in the same at suitable distances
apart and extending from one wall to the opposite one, in the bottom of which pits
the conveyors are arranged, while the top of the pits is covered in level with the
floor with openings and shoots at intervals for delivering the coal into the
conveyors.
Storage buildings with conveyors arranged as hereinbefore described may be
used for other powdered, granular or pebbly materials than 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. In storage buildings for powdered, granular or pebbly materials the use and
arrangement of conveyors for removing the material from the building by
abstracting it from the bottom of the stored material substantially as hereinbefore
described.
2. In storage buildings for powdered, granular or pebbly material the arrange-
ment of conveyors below the floor supporting said material and underneath openings
in the floor, shoots leading from the openings to the conveyors and doors or
equivalent means for opening and closing the openings more or less, substantially
as hereinbefore described and illustrated by the drawings.
3. The arrangement and construction of storage buildings and means for
discharging or removing the stored material therefrom substantially as herein-
before described and illustrated by the drawings.
