An Improved Rotary Nozzle.
I, FREDERICK NOEL MACKAY, of 242 York Road, King's Cross, in the
County of London, Engineer, do hereby declare the nature of this invention, to be
as follows:-
My invention relates to an improved rotary nozzle.
The object of my said invention is to construct a nozzle, which, when liquid is
caused to issue therefrom will be automatically rotated by the said liquid to sprinkle
or spread the same.
According to my invention, I place at the end of the delivery-tube or channel
for fluid, a chamber rotatable in suitable bearings and preferably closed except
for tangential or approximately tangential or inclined perforations in the wall
thereof. Through these perforations the liquid issues, and causes the said
chamber to rotate so that the issuing liquid is spread or scattered centrifugally.
In order that the said chamber may rotate easily I may provide ball bearings
therefor.
For example I may provide the said chamber with a flanged supply tube, and
with a screw-threaded bush encircling the supply-tube and adapted to be screwed
into the orifice at which fluid is delivered into the said tube. The bush is provided
with a ball-race, and balls are placed thereon so as to lie between said race and the
underside of the flange of the supply-tube, to support the chamber by upholding
the said flange during the rotation of the chamber and supply-tube.
In an alternative construction of such apparatus, the chamber is provided with
an internal central spindle which is attached thereto and turns therewith and is
flanged to form one part of the ball-race, the other part of which race is provided
on the support for the rotary spindle. The said support in turn, is carried by the
bush aforesaid.
In a further alternative construction two sets of ball-races are employed, one set
on the flange of the central internal spindle and its support, and the other set on
the circumference of the bush aforesaid and on the opposed portion of the
circumference of the chamber.
Such a rotary nozzle is particularly advantageous for use as a sprinkler in cask-
washers, churn-washers and the like, upon stationary, telescopic, or hand-directed
pipes, for the sprinkling effects the cleansing, as well as the filling, of the apparatus
under treatment.
The device is also very useful for application to jet-condensers, gas-absorbers,
water-softening apparatus, fire-extinguishing sprinklers, and other appliances.

1, FREDERICK NOEL MACKAY, of 242 York Road, King's Cross, in the
County of London, 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 :-
My invention relates to an improved rotary nozzle.
The object of my said invention is to construct a nozzle, which, when liquid is
caused to issue therefrom will be automatically rotated by the said liquid to
sprinkle or spread the same.
According to my invention, I place at the end of the delivery-tube or channel
for fluid, a chamber rotatable in suitable bearings and preferably closed except for
tangential or approximately tangential or inclined perforations in the wall thereof.
Through these perforations the liquid issues and causes the said chamber to rotate
so that the issuing liquid is spread or scattered centrifugally.
In order that my invention may be more clearly understood I will now describe
the same with reference to the accompanying drawings, in which
Figure 1 is a central section of my improved rotary nozzle showing it screwed
into an orifice in the main supply pipe for the liquid.
Figure 2 is an elevation thereof.
Figure 3 is a transverse section of the said nozzle.
Figure 4 is an elovation of a form of nozzle adapted to move in and out of a
chamber (shown in section) provided on the outlet of the main supply pipe, herein-
after more fully described.
Figure 5 is a view showing the nozzle projecting from the tube in the position it
occupies when the liquid is issuing therefrom."
Figure 6 is a longitudinal section of the same.
Figures 7 and 8 are central sections of larger forms of nozzles Figure 8 being
drawn to a much reduced scale.
A is a rotatable nozzle or chamber perforated with a number of small holes A'
which are more or less tangential. In the form illustrated in Figures 1, 2 and 3
the chamber A is provided with a flanged supply tube B screwed or otherwise
secured into a ring or collar C which is fastened in or formed by the base of the
chamber A. A screw-threaded bush D which is preferably tapered at D¹ as shown
encircles the supply tube B and is adapted to be screwed into a pipe E projecting
from the main supply pipe F which delivers the water or other Huid to the outlet
tube B. The flange of the tube B is constructed so as to form a ball race B₁ in
which hardened steel or phosphor bronze or other suitable balls G G are placed so
as to lie between the said race B' and a ball race D* formed on the screw-
threaded bush D. The liquid issuing from the nozzle through the tangential
orifices causes the nozzle to spin round. The liquid is thus dispensed in the form
of a rotating series of jets. The balls G take the longitudinal or axial thrust. This
form of nozzle somewhat modified I use as a rising nozzle for washing casks and the
like, see Figures 4, 5 and 6. In this construction the screwed bush D of Figures 1
and 2 is dispensed with and a collar or ring H is substituted for it with a ball race on
its inderside H. The chamber A is formed with a tubular extension I on which is
fixed a collar J, formed with a ball race J' on its upper side. K is a set screw to
lock the collar J. The balls G are enclosed between the races H', J. A
shoulder at the upper end of the extension I prevents the ring H from lifting
and so maintains the balls in position.
.
When no water or other fluid is passing into the nozzle, said nozzle is enclosed
by a tube L secured on the main supply pipe F and rests on the circumference of
the pipe orifice see Figure 4, and is then protected by the tube L from blows which

page_text: it might otherwise receive. When fluid is passing into the nozzle the pressure of it.
raises the nozzle till the ring or washer H is pressed into contact with the lower
face of the internal flange L provided at or near the mouth of the tube L see
Figure 5 in which position the nozzle projects through the end of the said
tube L.
In an alternative construction of rotary nozzle, see Figure 7, the chamber A is
provided with an internal central spindle A which is attached thereto or formed in
one part with the said chamber, and therefore turns with the chamber A. The said
spindle is flanged at A³ to form a ball race A'; the support M for the said rotary
spindle A also forms a ball race M. The support M is carried by arms D'D' of
the screwed bush D which is secured in the outlet from the supply pipe.
In a further alternative construction Figure 8 two sets of ball races and balls are
employed, one set on the flange A³ of the central internal spindle A' and its
support M to take the thrust of the water and the other set on the upper flange of
the part D and on the opposed portion A of the base of the chamber A to support
the weight of the nozzle.
The construction shown in Figure 8 is intended for large rotary nozzles, the
parts of which may be bolted together and also stayed if desired. The part D is
in this case made with an external Hange D' by which it may be bolted to the
main supply pipe.
Such a rotary nozzle is particularly advantageous for use as a sprinkler in cask-
washers, churn-washers and the like, upon stationary, telescopic, or hand-directed
pipes, for the sprinkling effects the cleansing, as well as the filling, of the apparatus
under treatment.
The device is also very useful for application to jet-condensers, gas-absorbers,
water-softening apparatus, fire-extinguishing sprinklers and other appliances.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. For delivering and distributing liquid, a nozzle mounted to rotate freely and
furnished with tangential or inclined outlet orifices, for the purpose specified.
2. The combination, with such a nozzle, of ball bearings to reduce the friction
of rotation, substantially as described.
3. Such a rotary nozzle mounted within an outer tube and capable of axial
movement therein, substantially as, and for the purpose, specified.
4. A rotary nozzle constructed substantially as described with reference to
Figures 1, 2 and 3 or to Figures 4, 5 and 6 or to Figure 7 or Figure 8 of the
accompanying drawings, and operating as specified.
