Improvements in Combined Apparatus for Discharging Water
Jets and Spray.
I, JOHN COCKBURN of No. 3 Thistle Place, in the City of Edinburgh, Foreman to
the North British Rubber Company, Limited, do hereby declare the nature of this
invention to be as follows:-
:-
My invention relates to twin water directors of the kind wherein a central jet
nozzle is fitted in conjuction with a perforated plate or rose and which is provided
with a cock or plug for directing the discharge of water either in the form of a solid
jet through the nozzle or as spray through the rose plate and the invention has for
object to lessen the cost of production and to simplify and otherwise improve the
apparatus.
In lieu of attaching the rose plate to the conical part of the body of the apparatus
by means of a screw formed within the flange or rim of the rose and separately
attaching the central nozzle I form upon the inner side, or mainly upon that side of
the rose plate a central tubular screw boss which forms in whole or in part the solid
jet nozzle and which is attached by screwing to a pap or stem forming part of the
solid jet waterway in the body of the apparatus a packing of rubber, leather or similar
material against which the end of the boss or stem bears being provided to maintain
a tight joint. The flange or rim of the rose plate has formed in it an annular recess
into which is fitted a ring of rubber or other packing and when the rose plate which
fits over the conical part of the apparatus is attached as above described a rim on said
conical part presses on said packing; or a recess may be formed in the rim of the
conical part to receive the packing ring and a lip or flange formed on the rose plate
to bear on said ring a tighter joint being obtained in either of these ways than by the
use of the usual screw attachment. The plug or stop cock in lieu of having a three
way channel as usual, has a straight slot or passage through it and the seat for it on
the body of the apparatus has a recess or pocket formed in it at the inlet way so that
while on turning the cock to open one end of said slot to the water way for the solid
jet or to an orifice leading into the chamber formed in the conical part the opposite

page_text: end of the slot remains open to the supply tube which is provided for attachment to
a hose pipe but upon turning the cock to close off the discharge of water both ends
of the slot may be closed by the scat. The cock or plug has a square on its end upon
which is fitted a lever handle for turning the cock. The water way is formed entirely
within the conical part of the apparatus and leads direct from the supply pipe.

COMPLETE SPECIFICATION.
Improvements in Combined Apparatus for Discharging Water
Jets and Spray.
I, JOHN COCKBURN of No. 3 Thistle Place, in the City of Edinburgh Foreman to
the North British Rubber Company Limited 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 twin water directors of the kind wherein a central jet
nozzle is fitted in conjunction with a perforated plate or rose and which is provided
with a cock or plug for directing the discharge of water either in the form of a solid
jet through the nozzle or as spray through the nozzle or as spray through the rose
plate and the invention has for object to lessen the cost of production and to simplify
and otherwise improve the apparatus.
In lieu of attaching the rose plate to the conical part of the body of the apparatus
by means of a screw formed within the flange or rim of the rose and separately
attaching the central nozzle I form upon the inner side or mainly upon that side of
the rose plate A (as represented in the accompanying drawings which illustrate the
combined jet and spray apparatus in elevation at figure 1 and in section at figure 2)
a central tubular screw boss B which forms in whole or in part the solid jet nozzle
and which is attached by screwing to a pap or stem C forming in whole or in part
the solid jet waterway in the body of the apparatus, a packing of rubber, leather or
similar material against which the end of the boss or stem bears being provided if
required to maintain a tight joint. The flange or rim a of the rose plate A has formed
in it an annular recess a¹ into which is fitted a ring d of rubber or other packing and
when the rose plate A which fits over the conical part D of the apparatus is attached
as above described a rim d' on said conical part presses on said packing; or a recess

page_text: may be formed in the rim of the conical part to receive the packing ring and a lip or
flange formed on the rose plate to bear on said ring a tighter joint being obtained
in either of these ways than by the use of the usual screw attachment. The plug
or stop cock E in lieu of having a three way channel as usual has a straight slot or
passage e through it and the seat for it in the body of the apparatus has a recess or
pocket formed in it at the inlet way y so that while on turning the cock E to open
one end of said slot e to the water way for the solid jet as indicated by dotted lines
or to an orifice leading into the chamber D¹ formed in the conical part D as indicated
by the full lines in figure 2 the opposite end of the slot remains open to the supply
tube G which is provided for attachment to a hose pipe; but upon turning the cock E
to its mid position to close off the discharge of water both ends of the slot are closed
by the seat. The cock or plug E has a square on its end upon which is fitted a lever
handle H for turning the cock. The water way is formed entirely within the conical
part of the apparatus and leads direct from the supply pipe.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
A combined apparatus for discharging water jets and spray constructed and arranged
to operate substantially as described
