PROVISIONAL SPECIFICATION.
Improvements in Water Jet Apparatus adapted to be used in the
Extinction of Fires.
I, JAMES SEXTON SIMONDS, of Winchester House, Southwark Bridge Road,
in the County of Surrey, Chief Officer of the Metropolitan Fire Brigade, do
hereby declare the nature of this invention to be as follows:-
The object of this invention is to direct a stream of water from an elevated
position upon the upper stories of a building and to enable an attendant at the
ground level to control the direction of the water jet.
At the top of a fire ladder or escape I provide a frame or platform on to which
the jet apparatus can be fixed. The water is led up to this platform by a hose
which is held in a coupling on the underside of the platform.
This jet apparatus consists of a flanged tube which is held upright in a gland
fixed upon the platform. The tube carries an arc of teeth into which a worm
gears. The spindle of the worm is carried by bearings secured to the gland and
on the end of the spindle is a pulley receiving an endless chain or rope. By means
of the chain the flanged tube can be rotated about its vertical axis. The flanged
tube terminates in a lateral mouth or opening to which a nozzle is adapted by an
universal or ball and socket joint. There is a toothed arc attached to the ball
portion of the joint concentric with it; this are lies within the mouth and a pinion
gears into it. The pinion is carried by a spindle projecting outside the tube. On
the outer end of the spindle is a pulley which can be turned by another endless
rope or chain, thus the nozzle is moved through an angle radially and in a
vertical plane.
In place of employing a hose, one of the uprights of the ladder may be tubular
for the water to be supplied through it.

Extinction of Fires.
I, JAMES SEXTON SIMONDS, of Winchester House, Southwark Bridge Road,
in the County of Surrey, Chief Officer of the Metropolitan Fire Brigade, 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:-
The object of this invention is to direct a stream of water from an elevated
position upon the upper stories of a building and to enable an attendant at the
ground level to control the direction of the water jet.
At the top of a fire ladder or escape I provide a frame or platform onto which
the jet apparatus can be fixed or it may be secured to the side of the ladder by
clamp irons or other suitable means. The water is led up to this platform by a
hose which is held in a coupling on the under side of the platform.
This jet apparatus consists of a flanged tube which is held upright in a gland
fixed upon the platform. The tube carries an arc of teeth into which a worm gears.
The spindle of the worm is carried by bearings secured to the gland and on the end
of the spindle is a
pulley receiving an endless chain or rope. By means of the
chain the Hanged tube can be rotated about its vertical axis. The flanged tube

In order that my said invention may be fully understood and readily carried into

DESCRIPTION OF THE DRAWING.
Figure 1 is a transverse vertical section partly in elevation of an apparatus made
according to this invention.
Figure 2 is a section on the line a
Figure 1.
Figure 3 is a horizontal section through the arc of teeth on the flanged pipe.
Figure 4 is a horizontal section on the line y y.
Figure 5 is an end view of the nozzle.
The apparatus shown in these figures is secured with a water tight joint upon a
frame or platform at the top of a ladder or by means of clamp irons or other
suitable means to the side of the ladder, or like portable structure and a connection
is made with a hose for supplying water, the hose coupling being on the underside
of the platform.
A is a tube with a flange B which is held upright in a gland C which is secured
as already stated to the platform. The tube A carries an arc of teeth D into
which a worm E gears.
The spindle F of the worm E is carried by bearings G. G¹ secured to the
gland C and on the end of the spindle F is a pulley H. receiving an endless
rope I.
By means of the rope I. the flanged tube A can be rotated about, its vertical
axis. The flanged tube A terminates in a lateral mouth K to which a nozzle N is
adapted by a joint consisting of a ball L and socket M. A toothed arc P into
which a pinion Q gears is attached to the ball L concentric with it. The pinion Q
is carried by a spindle R held in bearings S S¹. On the outer end of the spindle R
outside of the tube A is a pulley T which can be turned by another endless rope W,
thus the nozzle N can be moved in a vertical plane.
By means of the ropes I and W which reach to the ground, the firemen can
direct the water in any direction whilst they are at a distance from the heat of
the fire.
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 1
claim is :-
1. A water jet apparatus consisting of a tube held in a gland, which cau be
rotated about its vertical axis and having a laterally directed nozzle which can
be partially rotated.in a vertical plane substantially as described.
2. A water jet apparatus.consisting of a flanged tube held in a gland, which can
be rotated by means of a worm gearing into an arc of teeth on the tube, such tube
having a lateral mouth and, adapted to the mouth. by a ball and socket joint a
nozzle which can be rotated by means of a pinion gearing into a toothed arc on the
ball part of the joint substantially, as described.
3. A water jet apparatus.substantially as described and shown in the drawings..
