EDWARD HODSON BAYLEY, of Newington Causeway, in the County of Surrey,
Engineer. "IMPROVEMENTS IN OR APPLICABLE TO CARTS OR VANS FOR DISTRI
BUTING WATER OR OTHER LIQUIDS OVER ROADS, WAYS, OR OTHER SURFACES."
My Invention relates to the distribution of liquids over or upon roads and land,
and has for its object the provision of improved means for regulating the extent in
width as required to which the said liquid is to be distributed, and also obtaining
a more uniform distribution of the said liquid over the surface of the road or
land.
According to one mode of carrying out my Invention the tank for containing the
liquid is divided by means of partitions into two or more chambers, or is fitted with
one or more supplementary tanks.
The main tank or main chamber of the tank, as the case may be, may be supplied
with liquid in the ordinary manner, whilst the supplementary tank, or tanks, or
chambers may be supplied from the main tank or chamber. It is preferred to employ
the main tank to supply a distributing pipe extending across the back of the tank
and the supplementary tanks for supplying other distributing pipes, which may be
either curved or straight, and arranged at an anglo to or parallel with the sides of
the tank.
An important feature of my Invention consists in the arrangement of the rear
distributing pipe, which is divided at the centre by means of a diaphragm secured
by bolts between flanges formed on the two portions of the pipe, the said two
portions having separate and distinct communication by suitable valves with the
tank with which they are connected.
To the bolts which fasten the two flanges are attached radial bolts, and in con-
nection with the radial bolts is employed a circular strap, which fastens the diaphragm
in its place, and enables it to be removed when required for cleaning the tubes
which form the rear distributor. Other flanges being suitably placed enable this
portion of the distributor pipe to be entirely removed, and plugs at the curved
extremity of the distributor pipes afford a means of flushing them by a flow of
water from the tank longitudinally through the pipes.
According to another mode of carrying out my Invention I employ a singlo tank
or chamber, and supply the liquid therefrom by means of pumps or suitable valves

page_text: to either one or more of the distributing pipes, as required, a suitable air chamber
being provided at the top of the tank or other convenient position. Similar pumps
or valves may also be employed in conjunction with the preceding arrangement for
the purpose of increasing the pressure on the fluid, so as to cause it to be thrown to
an increased distance. I also employ the following improved construction of distri-
butors, viz. In lieu of allowing the liquid from the tank to pass through holes
simply bored in the distributing pipes, I fit nozzles into the said holes, having conical
passages which prevent the jets of liquid (passing through them) from spreading,
and thus ensure the water being thrown to a greater distance.
.The side distributing pipes may either be connected to the back distributing pipe
in a similar manner to the two portions of the latter, or they may be arranged
separately therefrom as desired.
Suitable valves to be worked by the hand or foot of the driver of the vehicle are
provided, so as to admit of the liquid from the tanks being conducted therefrom as
required into either the whole or into any one or portion of the distributing pipes,
in order to regulate the distribution of the liquid either behind or on one or both
sides of the track as required.
The distributing pipes are supported by light brackets, and fittings are made as
light as possible compatible with strength and durability.
The connection between the side portions of the distributor pipes and the upper
tank is effected by means of pipes so arranged in shape and traverse (either inside
or outside of the van) so as to give the minimum friction to the water in passing
to its exit.
