PROVISIONAL SPECIFICATION.
An Improvement in Revolving Nozzles for Distributing Liquid.
I, EDWARD EUGENE DULIER, of Manor House, Mildenhall, in the County' of
Suffolk, retired Military Officer, do hereby declare the nature of this invention to
be as follows:-
My invention relates to the construction of revolving nozzles for distributing
liquid in such a manner that the friction which impedes their revolution is greatly
reduced, and consequently they can revolve with freedom and rapidity, causing
wide and effective distribution of the issuing liquid. For this purpose according
to one construction I fix centrally in the vertical supply pipe a bolt extending up
through a chamber from which the nozzles project, and having fixed on it
adjustably a disc made with a circular concave groove on its underside.
Under this disc is a similar disc fixed to and covering the nozzle chamber, and'
having on its upper side a groove corresponding to that of the disc above it.
In the underside of the lower disc there is a recess for packing covered by a
projecting collar of the central bolt.
In the grooves of the two discs are placed a number of balls to constitute a
ball bearing, which, taking the upward pressure of the nozzle chamber, reducés
the friction that would otherwise impede the rotation of the nozzle-chamber.
From this chamber project in a tangential direction two or more nozzles which
are uniformly arranged around the chamber so as to balance the internal pressure
on all sides. These nozzles may project in the plane of the chamber, each having
a spirally curved channel leading to it from the chamber, or the channels may
bend downwards and then with spirally curved channels horizontally outwards.
According to a modified construction, the central bolt is dispensed with and the
ball bearing is arranged between an outwardly projecting-flange-at the top of
the supply pipe and an inwardly projecting flange at the bottom of the chamber,
the flange of the pipe having a circular groove for the balls on its underside
and the flange of the chamber having a corresponding groove on its upper side.
Dated this 9th day of January 1896.

I, EDWARD EUGENE DULIER, of Manor House, Mildenhall, in the County of
Suffolk, retired Military Officer, 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 the construction of revolving nozzles for distributing
liquid in such a manner that the friction which impedes their revolution is greatly
reduced, and consequently they can revolve with freedom and rapidity, causing
wide aud effective distribution of the issuing liquid.

page_text: For this purpose according to one construction, which is shewn in vertical
section in Fig. 1 and in plan Fig. 2, I fix centrally in the vertical supply pipe A
a bolt B extending up through a chamber C from which the nozzles N N project,
and having fixed on it adjustably a disc D made with a circular concave groove on
its underside.
Under this disc is a similar disc E fixed to and covering the nozzle chamber C
and having on its upper side a groove corresponding to that of the disc D. In the
underside of the lower disc there is a recess for packing P covered by a disc of
leather or similar material and projecting collar of the central bolt B. In the
grooves of the two discs D and E are placed a number of balls F to constitute a
ball bearing which, taking the upward pressure of the nozzle chamber, reduces the
friction that would otherwise impede the rotation of the nozzle chamber. From
the chamber C project in a tangential direction two or more nozzles N which are
uniformly arranged around the chamber so as to balance the internal pressure on
all sides. These nozzles may project in the plane of the chamber, each having a
spirally curved channel leading to it from the chamber, or the channels may
bend downwards as shewn and then with spirally curved channels horizontally
outwards.
According to a modified construction shewn in section in Fig. 3 and plan Fig. 4
the central bolt B¹ projects up from a socket S which is screwed on the supply
pipe A and the nozzle chamber C' revolves around the socket S and bolt B¹ which
are grooved to prevent or lessen leakage.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In combination with a set of revolving nozzles a ball bearing the balls of which
are interposed between the revolving chamber which carries the nozzles and the
abutment against which the chamber is pressed, substantially as and for the
purpose set forth.
