PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Distributing or Spraying Liquids,
We, CHRISTOPHER JOSEPH WHITTAKER, and WALTER CHARLES BRYANT, both of
Globe Chemical Works, Church, in the County of Lancaster, Chemical Manu-
facturers, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide a simple and efficient means of dis-
tributing or spraying liquids over a large surface, and the invention is specially
applicable to distributing sewage over the surface of aerated filters,, on which
filters, for their most efficient working it is necessary that the sewage should be
uniformly distributed so that no part of the filter may become temporarily water-
logged. No method or apparatus heretofore has accomplished the distribution
satisfactorily.
Our invention consists essentially in making use of two or more hollow arms
fixed (preferably tangentially) into a hollow central boss which is free to revolve
on antifriction ball bearings on a stand pipe. Openings or passages are provided
in the stand pipe and in the central boss through which liquid may pass from
a supply pipe to the hollow arms. The hollow arms are provided with holes so
arranged that the force of the liquid issuing from such holes causes the bollow
arms and boss to revolve round the stana pipe the friction being reduced very
considerably by means of the ball bearings. The issuing liquid is thereby
uniformly distributed or sprayed over a comparatively large area with the use
of few distributing pipes. The fixing of the hollow arms tangentially into the
boss also assists in causing the arms to revolve.
Under another modification the hollow arms are fixed into an annular cylinder
forming the central boss which is carried on ball bearings on a stand pipe. A
nozzle on the stand pipe delivers the liquid into the annular cylinder at such a
head as is sufficient to cause such liquid to flow through the hollow arms and the
holes therein as before described.
The ball bearings in both modifications are so disposed as to be effectively pro-
tected against the action of the liquid or of the weather.

DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a plan and Fig. 2 is a side view of apparatus for distributing liquids,
constructed according to our invention. Fig. 3 is a vertical section on an
enlarged scale of the central part of the apparatus and Fig. 4 is a horizontal
section at the line A A on Fig. 3. a are hollow arms conveniently made of tubes
and fixed at a tangent into a central boss b which is hollow and surrounds the
stand pipe c upon which the boss is supported and round which it is free to
revolve. d are ball bearings arranged between the upper part of the stand nipe
and the upper part or cover e of the boss. A close joint is made at f by packing
or otherwise, between the boss and stand pipe sufficient to prevent access of
liquid to the ball bearings but not to hinder free revolution of the boss. The
cover e encloses and protects the bearings from the rain or weather, so that they
are not liable to corrosion. is a centring point to prevent any unequal wear
or grinding at the joint f. h is a supply pipe for the liquid to be distributed
leading into the passage i in the stand pipe. jare openings preferably arranged
tangentially in the stand pipe and leading from the passage i into the hollow k
of the boss. 7 are passages in the boss leading to the hollow arms a so that
liquid can pass from the supply pipe h to such arms. The joint at f¹ is made close
by packing or otherwise to prevent escape of liquid. m are holes arranged in
the sides of the arms a through which the liquid flows in jets so that the reaction
causes the arms and boss to revolve thus distributing the liquid uniformly over
a surface, say of a filter bed n. are stavs from a central pillar for supporting
the outer ends of the arms a. The stand pipe may be supported in any desired
way but preferably on a base piece which may be formed as a dish to receive any
leakage of liquid from the hollow of the boss. The base piece may be carried
en a pillar such as r. g is an overflow pipe for any leakage.
Fig. 5 is a vertical section of a modification under our invention in which the
central boss is formed as an annular cylinder into which the hollow arms a

page_text: are fixed tangentially. c is a stand pipe carried on a base piece q. d are the
ball bearings arranged between the upper part of the boss or cylinder and the
stand pipe so as to be effectually protected from liquid or weather as before
described. s is a nozzle on the stand pipe by which means liquid is delivered
into the annular cylinder and flows therefrom into the hollow arms a. The
operation of this modification is the same as described under Figs. 1 to 4.
We do not claim broadly the distributing of liquid by revolving arms but
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
First. In revolving liquid distributing appliances the combination of a stand
pipe, a central hollow revolving boss or the like with hollow arms having holes
in the sides thereof, and enclosed ball bearings between the stand pipe and boss,
at or near the top thereof substantially as and for the purpose set forth.
Second. In revolving liquid distributing appliances the arrangement of the
hollow arms tangentially to the central boss substantially as and for the purpose
set forth.
