1, WILLIAM PHILLIPS THOMPSON F.C.S., M.1.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6, Bank Street, Manchester
both in the County of Lancaster, 118 New Street, Birmingham in the County of
Warwick and 31-High Holborn in the County of Middlesex, Civil 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 improvements in sprinklers. It is designed to have one
or more series of arins adapted to rotate rapidly, and one or more nozzles operated
by the first through intermediate mechanism adapted to rotate at a different rate
of speed, said last named arms being made adjustable to throw the water at any
desired angle of elevation. To this end, it consists in a reservoir formed by two
bell-shaped sections, the lower one stationary and the upper one rotatable thereon,
a hollow shaft extending vertically through said reservoir, having on its upper
extremity sprinkler arms of any suitable construction and on its lower extremity a
pinion meshing with a gear which, through intermediate mechanism, rotates the
upper section of said reservoir, said upper section carrying one or more nozzles
adjustable vertically.
In the drawing accompanying and forming a part of this application, "the"figure
is a sectional view partly in elevation, of the improved sprinkler.
In said drawing, B represents a base, upon which the sprinkler is mounted
and bande the stationary and rotary sections respectively of the reservoir. The
The
stationary section may be mounted upon said base in any convenient manner.
rotary section of said reservoir rests upon and is adapted to rotate upon
the stationary section in the manner hereinafter described: Passing vertically
through said reservoir is a hollow shaft carrying on its top sprinkler arms g and
on its lower extremity a rod extending down through the bottom of the reservoir.
Within the reservoir the hollow shaft has ports i opening into the reservoir,
through which water is supplied to the sprinkler arms at the top. Attached to
the stationary section of the reservoir is a bracket j. This bracket may be
attached in any convenient manner. As shown in the drawing, it is held in place
by a nut k inserted in the bottom of the stationary section of the reservoir. On
the lower extremity of rod h is a pinion meshing with a gear m keyed upon a
vertical shaft o mounted in said bracket. On the top of shaft o is a pinion p
meshing with a gear 9 having a flange r adapted to rest against a flange
the top of the stationary section of the reservoir. Said last named gear has an
upwardly extending flange t which extends above the bottom of the rotary section
of the reservoir, and said last named gear is rigidly keyed to said rotary section of
the reservoir by one or more set screws or in any other convenient manner, 80
that said section rotates with said gear. Pivotally mounted in said rotary section
of the reservoir are one or more nozzles v, said nozzles being adapted to rotate in
a vertical plane to throw the water at any desired angle, and to rotate with said
s near

page_text: rotary section of the reservoir. A packing nut w prevents the escape of water
from the reservoir at the top, and a packing nut serves the same function at the
bottom.
The operation of the improved sprinkler is as follows:—
Water under pressure is introduced into the reservoir through supply pipe e and
pipe A. It thence passes through ports i into shaft f and thence to the sprinkler
arms on the top of said pipe. It also enters the nozzles v direct from the reservoir.
The water escaping from the sprinkler arms causes the shaft to rotate, and the
rotation of said shaft through the pinion on the end of rod h and the intermediate
system of gears causes the rotary section of the reservoir to revolve at a rate of
speed determined by the gearing. As here constructed, the rotary speed of the
nozzles is much less rapid than that of the rotary arms.
The advantage of the improved sprinkler is that a much greater area can be
sprinkled thoroughly by the combination of the sprinkler arms and the nozzles
rotating at different speeds, the nozzles throwing the water much further than
the sprinkler arms. Again the nozzles may be adjusted vertically to throw the
water at different elevations, the throw of the water depending more or less upon
the elevation at which it is thrown and upon the rate at which the nozzles are
being rotated.
·
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
1. In a sprinkler, two sets of sprinkler arms rotating at different speeds, one
driven by the other through intermediate mechanism, substantially as and for the
purposes set forth.
2. In a sprinkler, two sets of rotary sprinkler arms rotating at different speeds,
one set driven by the other through intermediate and connecting mechanism,
the driven set capable of vertical adjustment to throw the water at any desired
angle, substantially as and for the purposes set forth.
3. In a sprinkler, a reservoir composed of two sections, one stationary and the
other rotatable thereon, a vertical pipe passing through said reservoir and open
thereinto, having on its upper end laterally extended sprinkler arms and on its
lower extremity a pinion adapted, through intermediate mechanism, to rotate the
upper sections of said reservoir, said upper section carrying one or more nozzles,
substantially as and for the purposes set forth.
