AN IMPROVED CONSTRUCTION OF APPARATUS FOR PRODUCING SPRAY WITH AUTOMATIC ADJUST- MENT TO SUIT VARYING PRESSURES
Year: 1884

page_text: We HENRY BROOKS of 7 Little Somerset Street Aldgate Engineer and
RICHARD MESTERN of 15 Gower Place Euston Square in the County of Middlesex
Engineer, do hereby declare the nature of our said invention for AN IMPROVED
CONSTRUCTION OF APPARATUS FOR PRODUCING SPRAY WITH AUTOMATIC ADJUST-
MENT TO SUIT VARYING PRESSURES, to be as follows:-
The object of this invention is to so construct or arrange an apparatus from
which water can issue in a circular sheet and then be dashed against the sides of a
tube as spray with sufficient force as to form a vacuum and a suction within said
tube for ventilating purposes. The valve is controlled by a spring the power or
force of which can be set by a screw nut as to limit the opening to suit varying
pressures.
According to our invention we form a bulbed or other shaped end on or attach
one to a water supply pipe-within this bulb is a cross bar having a hole in its
centre through which the spindle of the valve is passed and is held in position by
a screw nut,
Between this cross bar and another cross bar which is loose and capable of
turning round if desired we arrange a spiral or helical spring The lower part of
the spindle carries the valve of conical shape which fits a coned surface at the
lower end of the bulb so that the water may pass through and be projected in a
circular sheet like form or finely divided from the opening. The spindle is
continued below the valve and a many bladed rotator or screw' is fitted loosely
thereon, the rotator being held to the spindle by a nut or other device The
blades of the rotator are in the path of the sheet of water and are rotated by it
with sufficient force to break up the sheet and to distribute it as very fine spray
against the inner side of the tube within which the apparatus is centrally
arranged.
The spring ensures the valve being kept closed when no water is passing and it
can be so set as to permit of the valve opening to any desired extent, due to
pressure exerted.

RICHARD MESTERN of 15 Gower Place Euston Square in the County of Middlesex,
Engineer, do hereby declare the nature of our said invention for "AN IMPROVED
CONSTRUCTION OF APPARATUS FOR PRODUCING SPRAY WITH AUTOMATIC ADJUST-
MENT TO SUIT VARYING PRESSURES," 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 so construct or arrange an apparatus from
which water can issue in a circular sheet and then be dashed against the sides of a
tube as spray with sufficient force as to form a vacuum and a suction within said
tube, for ventilating purposes.
1.
The valve is controlled by a spring the power or force of which can be set by a
screw nut as to limit the opening to suit varying pressures.
According to our invention which we show on the annexed sheet of drawings
we form a bulbed or other shaped end A on or attach one to a water supply pipe B
within this bulb is a cross bar O having a hole in its centre through which the
spindle D of the valve E is passed and is held in position by a screw nut F.
Between the cross bar C and another cross bar G which is loose, and capable of
turning round if desired, we arrange a spiral or helical spring H. The lower part
of the spindle D. carries the valve E of conical shape which fits a coned surface at
the lower end of the bulb A so that the water may pass through and be projected
in a circular sheet like form or, finely divided spray from the opening. The
spindle D is continued below the valve E and a many bladed rotator or 'screw' I is
fitted loosely thereon, the rotator being held to the spindle by a nut or other
device.
-
The blades of the rotator, I are in the path of the sheet of water and are rotated
by it with sufficient force to break up the sheet and to distribute it as very fine
spray against the inner side of the tube J within which the apparatus is centrally
arranged.

The spring H ensures the valve being kept closed when no water is passing and
it can be so set as to permit of the valve opening to any desired extent due to
pressure exerted.

In the drawings Figure 1 a section and Figure 2 an elevation we show, the bulb
form of apparatus, this having the adjusting nut F inside the neck K of the
bulb A and upon the moveable cross bar G said bar being guided by ribs shown at
Figure 3.

According to this arrangement when the spring. H has to be reset from any
cause the nozzle (bulb) A has to be removed from the supply pipe B, but by the
arrangement shown at Figures 4 and 5 elevation and section respectively the
adjustment or setting of the spring H can be done from the outside without
removing the nozzle A, which we here show is of conical shape.
The spindle D is a fixture to the upper cross bar G (the loose cross bar being
dispensed with) and instead of the nut F we employ a screw D¹ which engages on
the spindle D to compress the spring H and to set the valve E the lower edge of
which is serrated or "milled" to break up the stream into fine jets.
Figures 7 and 8 show the application of our invention to two methods of
ventilation. By the first of these methods fresh air can be drawn in at the pipe J
by the vacuum created therein by the down rush of the spray as shown the air

page_text: being cooled or warmed according to the temperature of the water used, the air
passes under the bend L and issues into the room from the pipe M, the water from
the spray collects at the bottom of the pipe and runs off by the siphon N which
seals that passage against the escape of air by that channel.
In this Figure we have shown a duplicate nozzle A¹ in the up pipe M so that a
reverse action such as removing vitiated air from a room can be adopted. For this
purpose it is only necessary to turn off the cock P and open the cock Q to obtain
the spray in the pipe M The pipe J then becomes the outlet.
The pipe M may have several branches R R leading from, or to different parts
of a building such as we have indicated at Figure which shows the apparatus in
an apartment below a Billiard Room, this being ventilated in such manner that no
perceptible draught can be experienced by the players.
This example Figure 8 will make the utility of our invention clearly understood
with regard to sick chambers, hospital and infirmary wards especially in fever
wards in which it is necessary to ensure a gentle yet constant supply of fresh air
to or the withdrawal of contaminated air from the room or ward, in which case the
water, coming from a special source, may have a disinfectant mixed with it, as to
prevent pollution to any desirable extent.
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
The improved apparatus shown on the annexed drawings and as described for
the purpose or purposes set forth.
