PROVISIONAL SPECIFICATION.
Improvements in Water Cars for Moistening and Laying the
Dust in the Roads of Coal and other Mines.
I, ROBERT MURRAY WIGHT, of 42, Exchange Buildings, Cardiff, Glamorganshire,
South Wales, Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in water cars or vehicles carrying water for
moistening and laying the dust in the roads or tramways of coal and other mines,
and its object is to precipitate or settle the dust contained in the air as well as
moisten that already deposited on the road and adjacent parts.
A
For this purpose I employ a water car in which the water tank or reservoir is both
water-tight and air-tight and is adapted to withstand considerable internal pressure.
Provision is made for filling the tank with water under sufficient pressure to compress
the air, or a portion of the air, in said tank to the pressure required for use.
suitable sprinkler or sprinklers is or are fitted to the tank to sprinkle or spray the
water which is expelled (when sprinkler or sprinklers is or are turned on) by the air
pressure within whilst the car is travelling along the road or tramway.
As a modification the said tank may be partly filled with water at normal pressure
and a sufficient quantity of air may then be forced in to obtain the pressure
required.

Improvements in Water Cars for Moistening and Layig the
Dust in the Roads of Coal and other Mines.
I, ROBERT MURRAY WIGHT, of 42, Exchange Buildings, Cardiff, Glamorganshire,
South Wales, Merchant, do hereby declare the nature of this invention and in what
mauner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to improvements in water cars or vehicles carrying water for
moistening and laying the dust in the roads or tramways of coal and other mines,
and its object is to provide improved means to moisten and precipitate or settle the
dust contained in the air as well as moisten that already deposited on the road walls
and roof and adjacent parts.
For this purpose I employ a water car in which the water tank or reservoir is both
water-tight and air-tight and is adapted to withstand considerable internal pressure,

page_text: Provision is made for partially filling the tank with water under sufficient pressure to
compress the air in said tank to the pressure required for use. A suitable sprinkler
or sprinklers is or are fitted to the tank to sprinkle or spray the water which is
expelled (when the sprinkler or sprinklers is or are turned on) by the air pressure
within whilst the car is travelling along the road or tramway.
If a greater pressure is required than is thus obtainable the air in the said tank
may be compressed by forcing in additional air under pressure preparatory to charging
same with water.
Reference is made to the accompanying sheet of drawings forming a part of this
specification, in which similar letters of reference indicate corresponding parts in each
of the figures.
Figure 1, represents a side elevation of the car I employ.
Figure 2, is a plan view of the same partly in section and Figure 3, is an end view
of the same.
The cylindrical reservoir A is preferably made with concave or cambered ends B
and B to better withstand internal pressure. The cylinder is supported on the
wooden chocks or curved wooden rests C, C. fitting into the body of the carriage D
and is secured thereon by metal straps E, E the ends of which pass through the sides
of the carriage and are secured by the nuts E' underneath. The carriage runs on
two pairs of wheels F, F. A cock G is fitted in the back end B of the cylinder by
which the reservoir is charged with water and a discharge pipe H fitted with a cock J
is carried, by preference, round to the front of the reservoir and supplies the spraying
nozzle or nozzles or other spraying device.
The cross bar K at the back is provided for the attendant travelling on the car to
hold on by.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The means or method of discharging the water from a water car, viz.: the
employment of an air-tight cylinder and compressing the air therein by charging
same with water at a suitably higher pressure, substantially as herein shown and
described and for the purpose specified.
2. The improved water car, substantially as herein shown and described and
illustrated in the accompanying drawings..
