I, RUDOLPH SCHOMBURG of N° 28 Southampton Buildings, Chancery Lane in
the County of Middlesex, Engineer do hereby declare the nature of the said
invention for "IMPROVEMENTS IN SPRAYING APPARATUS FOR IMPREGNATING THE
ATMOSPHERE OF ROOMS WITH MEDICINAL OR CHEMICAL FLUIDS, ALSO APPLICABLE
FOR MOISTENING THE AIR GENERALLY, AND FOR PRODUCING CURRENTS OF AIR
FOR VENTILATION," to be as follows:-
According to my present invention I cause a jet of the liquid with which it is
desired to impregnate the atmosphere of a room to flow through a small opening
immediately in front of which are situated the points of three fine wires, so that
the liquid in impinging upon such points immediately on passing through the
aperture, is converted into exceedingly fine spray. The pipe with the spraying
arrangement is situated within the mouth of a larger tube that passes down some
distance and is then bent up again, terminating in a trumpet mouth, so that the air
drawn in at the one end by the action of the jet, becomes intimately mixed with
the fine spray as it passes through the tube, and issues in this impregnated condition
into the room. The lower part of the tube may conveniently be situated in a pan
or vessel containing the chemical or medicinal fluid which is to be converted into
spray, and which is forced by a force pump from the pan through the spraying
tube.
-
At the bend of the air tube an opening is formed through which any excess of
liquid not taken up by the air can escape back into the pan.
The orifice through which the liquid issues from the spraying tube is by
preference inade with a sharp edge, the metal being splayed on each side thereof,
whereby the risk of the orifice becoming obstructed is greatly diminished.
Although I prefer to employ threo wire points for the liquid to impinge against as
described, yet only two or a greater number than three may be employed.

page_text: It will be evident that the above described spraying apparatus may also be
used for simply moistening the nir with water or for merely utilising the current of
air produced thereby for ventilation. In these applications the requisite current of
water may be obtained from any convenient constant supply under pressure instead
of by means of a special pump. When employed for ventilation, the inlet orifice of 5
the air tube would of course be made to communicate with the atmosphere external
to the room to be ventilated.

I, RUDOLPH SCHOMBURG, of N° 28 Southampton Buildings, Chancery Lane in
the county of Middlesex, Engineer, do hereby declare the nature of my invention
for "IMPROVEMENTS IN SPRAYING APPARATUS FOR IMPREGNATING THE ATMOSPHERE
OF ROOMS WITH MEDICINAL OR CHEMICAL, FLUIDS, ALSO APPLICABLE FOR MOISTENING
THE AIR GENERALLY, AND FOR PRODUCING CURRENTS OF AIR FOR VENTILATION
AD
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
According to my present invention I cause a jet of the liquid with which it is
desired to impregnate the atmosphere of a room to flow through a small opening
immediately in front of which are situated the points of three fine wires, so that
the liquid in impinging upon such points immediately on passing through the
aperture, is converted into exceedingly fine spray. The pipe with the spraying
arrangement is situated within the mouth of a larger tube that passes down some
distance and then passes up again, terminating in a trumpet mouth, so that the air
drawn in at the one end by the action of the jet, becomes intimately mixed with
the fine spray as it passes through the tube, and issues in this impregnated con-
dition into the room. The lower part of the tube may conveniently be situated in
a pan or vessel containing the chemical or medicinal fluid which is to be converted
into spray, and which is forcod by a force pump from the pan through the spraying ·
tube.
At the bend of the air tube an opening is formed through which any excess of
liquid not taken up by the air can escape back into the pan.
The orifice through which the liquid issues from the spraying tube is by
preference made with a sharp edge, the metal being splayed on each side thereof,
whereby the risk of the orifice becoming obstructed is greatly diminished: Although
I prefer to employ three wire points for the liquid to impinge against as described,
yet only two or a greater number than three may be employed.
It will be evident that the above described spraying apparatus may also be used
for simply moistening the air with water or for merely utilising the current of air
produced thereby for ventilation. In these applications the requisite current of
water may be obtained from any constant supply of water under pressure instead
of by means of a special pump. When employed for ventilation, the inlet orifice of
the air tubo would, of course, be made to communicate with the atmosphere external
to the room to be ventilated.
Fig. 1 of the accompanying drawings shows a part vertical section of the above
described improved spraying apparatus, Fig. 2 shews a plan, and Fig. 3 shews a
sectional elevation to a smaller scale of the complete apparatus in a portable form.
A is a nozzle with small opening A', through which a jet of liquid is forced by the
hand pump E, drawing from the vessel D containing the liquid of which the spray

page_text: is required to be produced. Opposite the opening of the nozzle are situated three
points B so that the liquid issuing from the orifice, in impinging upon these points
is converted into a very fine spray, which is projected down the one limb of the
bent tube C in the open end of which the nozzle is fixed, thereby inducing a
current of air down the tube which air becomes effectually impregnated with the
moisture, and rising up through the other limb of the tube escape through the
orifice C³ thereof into the room or other locality. Any surplus liquid from the spray
that is not taken up by the air escapes through the opening C in the bend of the
tube, back into the vessel D again.
The metal round the orifice of the jet is bevelled off on both sides, as shewn, so
as to form a sharp edge, whereby the choking of the orifice by deposit is more or
less prevented.
The part B¹ of the nozzle is capable of adjustment on the part A, so as to
enable the distance of the points B from the orifice A¹ to be regulated as may be
desired.
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.
1, The construction of spraying apparatus wherein the liquid flowing under
pressure through a small opening is caused to impinge upon points presented to the
opening, whereby the liquid is converted into fine spray, substantially as herein
described.
2, In spraying apparatus, the combination of the nozzle A and points B B, with
the bent air tube C having an orifice C¹ at its bend through which any surplus
liquid from the spray passes back into the vessel D, while the impregnated air
passes up and escapes through the orifice C³ substantially as herein described with
reference to the accompanying drawings.
