Engineer do hereby declare the nature of this invention to be as follows:-
My invention refers to improvements in apparatus for converting at will a jet
from a branch-pipe to a spreading jet-and means for shutting off the jet and
re-opening same.
Between the smaller end of an ordinary branchpipe I introduce a sleeve or
cylinder screwed on its outer surface and with smooth bore; and by a female or
socket I screw this on to the branchpipe, and at the end of cylinder away from
the socket is a screwed male end on to which an ordinary jet piece or nozzle is
screwed between the branchpipe end and the nozzle end of cylinder which is
screwed on the outer surface, I place a running nut or sleeve having gudgeons or
pins projecting from its outer surface and radially with the axis of cylinder and
to these I connect links, or a frame, which carries or supports a sphere or segment
of a sphere or a cone, the convex surface of sphere or segment or apex of cone
facing the orifice of jet. The links vibrate on the pins or gudgeons of sleeve and
allow the sphere or segment of sphere or cone to cover the orifice of jet pipe
or to move clear thereof. When the sphere or segment of sphere or cone is in
front of the orifice of jet, a spreading jet or conical spray is formed and when clear
the jet issues uninterruptedly in cylindrical form, again when the sphere, or
eegment of sphere or cone is in front of orifice by screwing the sleeve downwards
towards the branch pipe the sphere or segment of sphere or cone is drawn towards.
the orifice of jet and regulates the quantity of water issuing as a spreading jet,
and when sufficiently screwed down shuts the jet off entirely-the vibrating
movement of the links and with this the sphere or segment of sphere or cone can
be regulated by the hand or by a screw or lever attachment and guards or stops
are formed to limit the movement of the links-the sphere or segment of sphere
or cone can be fitted to the links or frame so as to be removed or replaced by one
form or another and the sleeve may be part of the branch pipe or of the jet or of
each independently, but as described the jet can be altered and replaced by jets of
different sizes as the case may require. This apparatus may be adapted to
existing branch-pipes and existing jets or made of special form. The frame can
be made of flut section with cutting or knife edges at that part to which the sphere
or segment of sphere or cone is attached so as to prevent the spreading stream
from being interrupted thereby. The sphere or segment of sphere or cone can be
varied in shape so as to produce a spreading jet of varying shape. For small jets
such as for garden purposes, where a shut off may not be required I can modify
the shape of the frame supporting the spreading attachment and use a single arm
or double arm frame and use or dispense with the shut off.

Improvements in Nozzles for Hose. Pipes for Fire Extinguishing
and other Purposes.
JAMES CADOUX HUDSON 75 Upper Ground Street Blackfriars Road Londop
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 refers to improvements in nozzles, for hose pipes for fire
extinguishing and other purposes by means of which I can convert, at will, a jet
from a branchpipe, to a spreading jet, and means for shutting off. the jet and
reopening same.
At the smaller end of an ordinary branchpipe I introduce a tube or cylinder
screwed on its outer surface. and with smooth bore ; and by a female or socket
I screw this on to the branch pipe end-and at the end of cylinder away from the
socket is a screwed male end on to which an ordinary jet piece or nozzle is
screwed between the branch pipe end and the nozzlo end of cylinder which is
screwed on the outer surface I place a running nut or sleeve having gudgeons or
pins projecting from its outer.surface and radially with the axis of cylinder and to
these I connect links or afframe which carries or supports a sphere or segment of
a sphere; or a cone, the convex surface of sphere or segment or apex of cone
facing the orifice of jet.
The links vibrate on the pins or gudgeons. of sleeve and allow the sphere or
segment of sphere or cone, to cover the orifice of jet pipe or to move clear
thereof.
When the sphere or segment of sphere or cone is in front of the orifice of jet
a spreading jet or conical spray is formed, and when clear- the jet issues un-
interruptedly in cylindrical form-again when the sphere or segment of sphere or
cone is in front of orifice by screwing the sleeve downwards towards the branch-
pipe the sphere or segment of sphere or cone is drawn towards the orifice of jet
and. regulates the quantity of water issuing as a spreading jet, and when
sufficiently sorewed down shuts the jet off entirely the vibrating movement of the
links and with this the sphere or segment. of sphere or cone can be regulated by
the band or by a screw or lever attachment and guards or stops are formed to
limit the movement of the links. The sphere or segment of sphere or cone can be
fitted to the links or frame so as to be removed or replaced by one form or another
and the sleeve may be part of the branchpipe or of the jet or of each independently
but as described the jet can be altered and replaced by jets of different sizes as the
case may require: The apparatus may be adapted to existing branchpipes and
existing jets or made of special form. The frame can. be made of flat section with
cutting or knife edges at that part to which the sphere or segment of sphere or
cone is attached so as to prevent the spreading stream from being interrupted
thereby. The sphere or segment of sphere or cone can be varied in shape' so as
to produce a spreading jet of varying shape. For small jets such as for garden
purposes when a shut off may not be required I can modify the shape of the frame
supporting the spreading-attachment and use a single arm or double arm trume
audiuse or dispense with the shut off. In order that my said invention may be
must fully understood and readily carried into effect, I will proceed to describe the
drawings hereunto annexed.

or jet pieces.
Fig. 18-is a form of jet in which the vibrating movement of 'spreader is controlled
and regulated by a screw.
Fig. 19 is a sectional plan of the same.
Fig. 20 is an elevation of a form of jet in which the vibrating movement of
spreader is controlled and regulated by a lever.
Fig. 21 is a sectional plan of the same.
Figs. 22 and 23 are plan and elevation of a modification of the form of jet shewn
at Figs. 20 and 21.
Referring now to Figs. 1. 2 and 3 (A) is the body of jet, (B) the screwed cylinder
connected to the body of jet (A) by a screwed joint (C) and at the opposite end,
having an interior screwed or female boss (D) to receive the branchpipe. (E) is
a running nut on the upper side of which is a bridle or 'swivel (F) having pro-
jecting pins (G)(G) formed on its outer circumference and upon these pins (G) (G)
the sides of frame or liuks (H) (H) and spreading attachment vibrates. "The
upper part of links (H) (H) are connected by a bar ()upou'which is 'formed 'the
huss () to receive the spreader (K) or jet pieces (0) (0) (0) the 'section of
bar (1) being of an acute triangle 'having cutting or knife edges (L) (L). On the
outer part of body of jet (A) are slots' or grooves (M) (M) to receive the
pius (N) (N) on vibrating links (H) (H) and which form guards or stops
to the movement of the links (H) (H) and regulate the action of the spreading
attachnient. The pins (N)i(N) are shewn at Figs. 2 and 3 being placed at
point off the vertical centre line' of links (H) (H) and bore of jet'; but tho
pins (N) (N) may be on the centre line of bore of jet or in any other desired
position. The slots (M) (M) are of such a form as to give the required movement
to the spreader or jet piece-(K) being for a 'part of its length parallel with the
centre of bore of jet. The remaining part of the grooves or slots (M) (M) being
at an angle with the same.
In Fig. 8 the running nut (E) is sliewn in its lower position the pins (N) (N)
being at the bottom of slots (M) (M) and the spreader (K) closed over the mouth
of jet (A).
In Fig. 9 the running "out- (E) has been partly raised together with the
pins (N) (N) and spreader (K) the movement given to spreader being' vertically
or in the direction of the centreline of bore of jet. The pins (N) (N) having
arrived at that part of the slots (M) (M) at' which the vertical direction terminates
a further upward movement of the running nut (E) causes "the pins (N) (N) to
enter and travel in that part of the slots (M) (M) in which the direction is at
anwangle with the vertical or centre line' of' bore of jet, and by continuing the
upward movement of running nut (E) the pin is brought to the position shewn
attFig. 10. in which the spreader (K) is thrown clear of the jet' orifice, allowing a
full bore and uninterrupted jet. Then with the spreader (K) in the boss (J)'there
may be either a spray Fig: 9, a solid jet Fig. 10, or the nozzle" may be entirely
closed Fig. 8. In Fig. 10 the links (H) are in such a position that the spreader (K)
may be removed and replaced by any of the jet pieces (0) (0) (0) without

page_text: interrupting the jet issuing from the nozzle. This having been done and the
nut (E) lowered as shewn at Fig. 11 a solid reduced jet (P) and also spray (Q)
can be obtained. By lowering this running nut (E) to the position shewn at
Fig. 8. a reduced solid jet only is obtained through the jet piece (0) or by raising
the nut (E) into the position shewn at Fig. 10 the jet piece (O) is thrown clear of
the jet orifice and a full bore solid jet is obtained. In Fig. 6. the diameter of bore
for the solid jet is reduced from that shewn at Fig. 5. The spreading surface of
the jet pieces 4, 5 and 6 may be of the form of a segment of a cone as shewn
in full lines or of a segment of a sphere as shewn in dotted lines or of any
other suitable form. In Fig. 7 the shank (U) of jet piece (0) is continued
beyond the top of the bar (1) and boss (J) and screwed to receive a rose or
perforated piece (R). To enable the jet pieces (0) (0) (02) and spreader (K)
to be readily removed from or inserted into the boss (J) I form in the boss (J)
a groove (S) into which is inserted a wire spring (T) of steel. German silver or other
suitable material the section of wire being preferably a circle but wire of other
section may be used. The wire spring (T) is slightly smaller in diameter than the
bore of the boss (J) and shank of spreader (C) or jet pieces (0) (0) (0²) any
one of which being introd need into the boss (J) the spring (T) is opened, and by
reason of its tendency to return to its normal condition the spring (T) grips the
shank (U) of spreader (K) or jet pieces (0) (0) (0) with sufficient pressure to
prevent the same falling out of the boss (J) but at the same time allowing the
sprender (K) or jet pieces (0) (0) (0) to be removed by a slight pressure on
the upper side and an equally ready method of replacing.
Referring to Figs. 12, 13 and 14 (A) is the body of jet (B) the screwed cylinder
directly attached to the brauchpipe (V) (E) is the running nut with swivel (F)
and projecting pins (G) (G) and vibrating links (H) (H') connected by the bar (1)
carrying the boss () to receive the spreader (K). Upon the links (H') (H) is
formed the stops (M) (M) to guide and controll the vibrating movement of the.
links (H) (H). At Fig. 13 the spreader is shewn directly over and closing the
orifice of the jet (A) and guided in this position by the stop. (M).
By raising the nut (E) to its highest position as shewn at Fig. 14 and bringing
the vibrating links over to the right the stop (M) is brought in contact with the
body of jet (A) and the spreader (K) is thrown clear of the jet orifice allowing a
Bolid and uninterrupted jet. In Figs. 15, 16 and 17 the screwed cylinder and
running out in connection with shut off is dispensed with. (A) is the body of
jet, (H) (H) the vibrating links connected at the top by the bar (1) carrying
boss (J) to receive the spreader (K). The pins (G) (G) are formed on the
outer circumferenre of the lower part of body of jet (A). The motion of vibrating
links (H2) (H) is controlled by the stops (M) (M³) formed upon and connecting
tho links (H) (H). In Fig. 16 the spreader (K) is shewn directly over centre
of bore of jet being guided in this position by the stop (M³). By moving the
vibrating links (H) (H2) over to the left until the stop (M2) comes in contact with
the body of jet the spreader is thrown quite clear of jet orifice allowing a solid and
uninterrupted jet. In Figs. 18 and 19 (A') is the body of jet, (³) (H) the
vibrating links, (G) G¹) the pins formed on the outer circumference of lower part
of jet, (W) is a bar connecting the vibrating links (H) (H³), and carrying a
boss (X) screwed to receive the thumbscrew (Y) by meaus of which the vibrating
movement of links (H) (H) is controlled. Z is a spiral spring connected to the
links (H) (H) and by means of which the links (H) (H) are brought to the
vertical position after having been thrown over by the screw (Y) to the dotted
position where the spreader (K) is clear of the jet orifice.
In Figs. 20 and 21 a lever (BI) with fuleruin (C) is substituted for the screw (Y)
Figs. 18 and 19. (W¹) is a bar formed on aud connecting vibrating links (H) (H)
with a jaw (D) to receive the boss (E') of lever (B) working on the pin (F), the
bar (W) forms a stop by means of which the spreader (K) is brought over and in
a direct line with the centre of bore of jet. The other letters of reference apply
as at Figs. 18 and 19.

page_text: In Figs. 22 and 23 another form of lever (B) and spring (Z') is shewn, (H) are
the vibrating links with the bar (W) and lever (B), (W) is a stop formel on and
connected to the links (H) (H) and by means of which the spreader is brought
over and in a direct line with the centre of bore of jet.
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
Firstly. The arrangement of applying a spraying piece or spreader which can be
moved to the front of a jet or nozzle aud moved clear of that jet for the purpose of
breaking up an issuing jet into spray or allowing it to issue in a solid streain in the
manner illustrated & described.
Secondly. The arrangement of vibrating frame, sleeve and scrow and guide and
stop attachments by which such spraying piece can be held free of the issuing jet
and brought in front of same and regulated when spraying the jet and caused to
shut off the issuing jet as illustrated and described.
Thirdly. An arrangement for altering the spraying piece, to a piece with central
hole of varying size, or rose spreader or other desired form of jet or spray, then
varying the size of jet and description of spray as illustrated and described.
Fourthly. The above arrangements used separately or combined.
Fifthly. Also the arrangement of frame carrying the spreading piece in
connection with the stops, screw or lever used to actuate the frame to bring the
spreader in front of the issuing jet in the simple form of spreader and jet as
illustrated and described.
