Improvements in Apparatus for Preventing Accumulations of
Coal Dust in Mines and other Places.
We, HUGH BELL of Middlesbrough in the County of York, Ironmaster, ADDISON
LANGHORN STEAVENSON, of Holywell Hall, in the County of Durham, Mining
Engineer, and RICHARD HARLE of Browney Colliery, in the County of Durham,
Colliery Viewer, do hereby declare the nature of this invention to be as follows:-
According to this invention the coal and dust on the tops of the tubs, are
automatically damped preferably before the loaded tubs are carried to the main haulage
roads, and there exposed to the intake or other air currents.
The arrangement consists of a small tank, where other sources of supply are not
available, containing water, placed at a convenient point and at a suitable level above
the tubs, preferably at or near the flats or landings where the tubs are arranged to
start. The water is carried from this tank to a perforated pipe or outlet, so arranged
as to deliver a spray of water, to cover the area of the laden tub, as it passes under.
The connection with the tank is provided with a valve worked by the tub, as it
travels along the rail. For this purpose at the point where the spray is fixed, the
tub wheel or other part of the tub passes over or strikes against a bar or other
arrangement actuating a lever connected with the valve in the outlet pipe, and the
speed of the tub, and valve are regulated so as to give a sufficient quantity of water
to each tub, to prevent the fine dust escaping to the surrounding atmosphere, or
depositing in the gallery it travels along. By this means all excess of water which
might damage the roadways, or haulage ropes, is obviated and the costly process of
watering over the whole distance of main roads with large quantities of water is
avoided.
This arrangement is intended to prevent the dust which is given off by the tubs,
but in mines where dust comes down from the screens and disintegrator a similar
arrangement may be made in the shaft or in the road near the shaft and in this case
the cages would, if found necessary, shut off the water whilst men are passing through
it either up or down.

page_text: Colliery Viewer, 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:-
According to this invention the coal and dust on the tops of the tubs, are
automatically damped preferably before the loaded tubs are carried to the main haulage
roads and there exposed to the intake or other air currents.
The arrangement consists of a small tank, where other sources of supply are not
available, containing water, placed at a convenient point and at a suitable level above
the tubs, preferably at or near the flats or landings where the tubs are arranged to
start. The water is carried from this tank to a perforated pipe or outlet, so arranged
as to deliver a spray of water to cover the area of the laden tub, as it passes under.
The connection with the tank is provided with a valve worked by the tub, as it
travels along the rail. For this purpose at the point where the spray is fixed, the
tub wheel or other part of the tub passes over or strikes against a bar or other
arrangement actuating a lever connected with the valve in the outlet pipe, and the
speed of the tub and valve are regulated so as to give a sufficient quantity of water
to each tub, to prevent the fine dust escaping to the surrounding atmosphere, or
depositing in the gallery it travels along. By this means all excess of water which
might damage the roadways, or haulage ropes, is obviated and the costly process of
watering over the whole distance of main roads with large quantities of water is
avoided.
This arrangement is intended to prevent the dust which is given off by the tubs,
but in mines where dust comes down from the screens and disintegrator, a similar
arrangement may be made in the shaft or in the road near the shaft, and in this case
the cages would, if found necessary, shut off the water whilst men are passing through
it either up or down.
Figure 1 is a transverse section and Figure 2 a longitudinal section of roadway
fitted with apparatus according to this invention. Figures 3 and 4 are enlarged local
sections.
a is a water tank, ba supply pipe leading from it, c is a spring valve on the pipe b,
and d is a perforated pipe connected to it. e is a lever pivotted at e and operating
the valve c. The lever e is connected by a rod f to the lever g pivotted at g¹ and
carrying the treadle / which is depressed by the wheels of the truck j in passing.
Figure 5 is an elevation and Figure 6 a plan showing the application of the
invention to a coal drawing shaft. In these figures the tank a is not shown and the
truck is replaced by the cage j but in other respects the arrangement is similar except
that the cage when it comes against the treadle or trip h turns off the water instead
of turning it on.
Figure 7 is a sectional elevation and Figure 8 a plan showing the application of
the invention to the screens above ground. In this case the trunnion of the
"kickup" k carries a crank pin connected by the rod f to the lever e operating
the valve c.
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. The combination with apparatus for moving or treating coal of a water jet
controlled by a valve operated by a moving part of the apparatus.
2. Apparatus substantially as described and shown at Figures 1 to 4 of the
drawings.
3. Apparatus substantially as described and shown at Figures 5 and 6 of the
drawings.
