Improvements in Sprinklers for use on Watering Carts.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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 centrifugal sprinklers which are attached to watering
carts or wagons and driven by suitable connections with the rear wheels of the
vehicle, and my improvement comprises a novel arrangement of two valve-guarded
ventages or nozzles which enable the jets of water to be thrown to either or both
sides of the street or roadway, from a single disc armed with suitable blades,
buckets or vanes, as hereinafter described.
In the accompanying drawing
Figure 1 is a rear elevation of a water sprinkler embodying my improvements.
Figure 2 is a plan of the same, the hanger being omitted and the main shaft
shown in section.
A represents a portion of the rear frame of a watering cart or wagon, or other
similar vehicle and B is a hanger depending rigidly from said frame, boxes b, b
being attached to said hanger for the support of a main vertical shaft C, the lower
end of which carries a disc D, armed with a series of concave buckets or vanes d.
The upper end of this main shaft has a bevel pinion E attached to it, which pinion
gears with a bevel wheel F of counter shaft G, the latter having a pulley or
sprocket wheel H, driven by a belt or chain connection with the hind wheel or axle
of the vehicle, the arrangement of these connections being such as to impart a high
velocity to the sprinkler proper D d. I is a pipe leading to the tank or barrel
and i i are branches connecting said pipe with chambers J J', the latter being
provided with valves K K', having stems koperated by suitable means.
LL' are ventages or nozzles reaching from these valve chambers down almost to
the buckets d.
In constructing this sprinkler care must be taken to arrange the gearing in such
a manner as to cause the disc D to revolve in the direction of the arrow seen in
Figure 2 or in other words, in the direction of the concave sides of the buckets or
vanes. Care must also be taken to locate the nozzles L L' about diametrically
opposite each other, in order that one of them may supply the front half of the disc
with water, while the other ventage supplies the rear half.
If the water is to be thrown to the left, while the vehicle advances the valve K¹
is opened so as to cause the disc to be supplied with water from the nozzle L'.
But if the water is to be thrown to the right the valve K is opened and the disc is
then supplied from the other nozzle L. When it is desired to throw water both to
the right and left, the valves K and K' are opened so as to bring the pair of
nozzles L L into service and thereby supply the front and rear portions of the disc
with sufficient fluid to sprinkle a street from curb to curb. It will thus be seen
that the present arrangement of sprinkler performs the work of two discs, such as
heretofore employed, simplifies the construction of the machine, reduces the weight
one half and renders the apparatus less liable to derangement. The dotted
lines II in Figure 2 indicate that the branches i¹ may be omitted and the
chambers JJ' be connected directly to the tank by independent supply pipes, if
desired.
Finally the nozzles L L' can be composed of upper and lower pipes coupled
together at so as to enable the ventages to be set at whatever angle may be the

page_text: most appropriate to secure the desired results. The exact angle, however cannot
be specified, inasmuch as it will vary with the size of the disc D, the velocity with
which it is driven and the shape of its buckets d.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
First. A centrifugal sprinkler consisting of a single plate or disc armed with a
series of buckets or vanes in combination with a pair of ventages having independent
cut off's one of which ventages discharges in the rear of said shaft, the jets either to
the right or left of the machine, or to both sides of the same, substantially as herein
described.
Second. In combination with a centrifugal sprinkler, a pair of angularly-
adjustable ventages or nozzles adapted to discharge water on the front and rear
surfaces of a single disc, each ventage being provided with an independent valve or
cut off, substantially as herein described and for the purpose above specified.
Dated this 10th day of March 1891.
