I BENJAMIN VERITY of 77 Hamilton Terrace London N.W. Engineer, do hereby
declare the nature of this invention to be as follows:-
This Invention relates to the ventilation and warming of buildings by the introduc-
tion of a current of fresh washed and if desired warmed air the current being
produced by the inductive action of a jet or jets of water whereby the air is cleansed
of floating impurities. The jet is in the form of a diverging annulus or cone and is
situated within an air tube or channel through which the current is to be conveyed,
the jet issuing from an annular nozzle supplied by tubes which have a free passage
for the air through the nozzle. Centrally opposite this annular nozzle and within the
hollow conical jet of water issuing therefrom is placed a deflector against which a fine
jet of water is directed whereby the jet is broken up into a fine cloudlike mist the form
and situation of the deflector being such as on the one hand to direct the air against
the main-conical jet and keep it under the inductive action of the latter and on the
other hand to cause the spray or mist to diffuse itself throughout the air current and
to take such a direction as to assist in the conveyance of the air which will thereby
be freed from any suspended impurities such as soot or dust. The hollow conical jet
of water is downwardly directed so that the force of gravity assists the pressure at
which the water issues from the nozzle and the down cast tube or passage within which
it acts communicates above with a suitable inlet and below with another or up cast tube
or passage whereby the fresh air is conveyed wherever required. The down cast tube
is preferably constructed of glazed earthenware to lessen the hissing noise produced
by the water striking against its sides. A suitable outlet is provided at the bottom of
the down cast shaft for carrying off the waste water from the jet.
When the apparatus is used for exhausting vitiated air from a building the down
cast shaft would be connected to the space to be ventilated and the up cast with any
suitable outlet.
The up cast tube or passage may be around or alongside of the down cast tube or
passage, and if it be desired to warm the air the up cast tube would constitute the
heater and be constructed with double walls through which hot water would be kept
constantly circulating by means of a dome shaped boiler also constructed of annular
form with double walls and acting as the chimney for an argand gas-burner placed
within it, the boiler being connected with the air heater by means of flow and return
circulation pipes.

page_text: I BENJAMIN VERITY of 77. Hamilton Terrace, London, N.W. 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 :-
This Invention relates to the ventilation and warming of buildings by the introduc-
tion of a current of fresh, washed, and, if desired, warmed air, the current being
induced by the inductive action of water jets and spray whereby the air is cleansed
of floating impurities.
Reference is to he had to the accompanying drawings forming part of this specifica-
tion, wherein Figure 1 represents an elevation, one half being in section, of the main
and secondary jet nozzles within the air tube or passage. Figures 2 and 3 shew
sectional elevations, at right angles to one another, of one arrangement of air tubes
or passages in which the jets are applied. Figure 4 is a perspective view of a
modified arrangement Figures 5 and 6 illustrate the arrangements for warming, as
well as for inducing and cleansing, the current of air, figure 5 being a vertical section
of the boiler, and figure 6 a vertical section of the hot water jacketted air tube. The
same letters of reference indicate the same parts in all the figures.
The main jet A is in the form of a diverging cone, and it is situated within an air
tube, passage, or shaft B through which the air current is to be conveyed, the jet
issuing from fine holes drilled in an annular nozzle C supplied with water by tubes D
which leave a free passage for the air through the annular nozzle C. The hollow cone
of water A is preferably downwardly directed, so that the force of gravity assists the
pressure at which the water issues from the nozzle, and the conical jet of water strikes
against the sides of the tube or passage B at a point about eighteen inches from the
nozzle and is thereby broken up, the water running down the sides of the tube B.
This down cast air tube B is preferably constructed of glazed earthenware to lessen
the hissing noise produced by the water striking against its sides.
Centrally opposite the annular nozzle C, and within the hollow cone of water A
issuing therefrom, is placed a hollow conical deflector E against which a fine secondary
jet of water is directed from a central nozzle F, the direction of this secondary jet
being preferably opposite to that of the main jet. This secondary jet on striking the
deflector E becomes broken up into a fine cloud-like mist which diffuses itself through
the air current and seizes hold of and throws down any suspended impurities such as
soot or dust.
The deflector E is attached to the under side of a hollow chamber G which occupies
a central position opposite the aperture through the annular nozzle C, the form and
position of this chamber G being such as to direct the air against the main conical
jet A and keep it under the inductive action of the latter. The chamber G with which
the nozzle F is connected by a pipe, as shewn, may be supplied with water from a
separate pipe, or from the same pipe as the main nozzle.
The down cast tube or passage B communicates, as shewn in figures 2 and 3, above
with a suitable inlet H, and below with another or upcast tube or passage 1, whereby
the fresh air is conveyed wherever required. A suitable outlet K is provided at the
bottom of the down cast tube for carrying off-the-waste water from the jet.

page_text: The apparatus may also be used for exhausting vitiated air from a building, in which
case, the down-cast tube would be connected to the apartment or space to be ventilated,
and the upcast tube I with any suitable outlet. Both arrangements of apparatus may
be applied to force air into and exhaust air from the same building at the same time.
The up cast tube or passage may be alongside of the down cast tube or passage, as
shewn in figures 2 and 3, or around it, as shewn in figures 4 and 6, and if it be
desired to warm the air, the upeast tube would constitute a heater, as shewn in figure 6.
In this case, the tube I is constructed with double walls of sheet metal forming a
closed chamber through which hot water is kept constantly circulating by means of
a suitable water heater.
The preferred form of water-heating apparatus consists of a dome shaped boiler L
constructed of annular form with double walls, and acting as the chimney for an
argand gas burner M placed within it, the boiler being connected with the air heater I
by means of flow and return circulation pipes N P. By means of this gas heated
boiler, the temperature of the current of air may be kept practically constant.
I would have it clearly understood that although I have, in the drawings, represented
the nozzle of circular form it may be square, oblong, or of other shape, providing
that it be annular or have an unobstructed central passage for the air through it,
which is an essential feature of this part of my Invention.
Having now particularly described and ascertained the nature of the said Invention
and in what manner the same is to be performed; I declare that what I claim is -
1. An apparatus for inducing and washing a current of air, the apparatus consisting
of an annular or hollow nozzle producing a diverging hollow jet of water playing
within and striking against the sides of an enclosing tube or passage, substantially
as herein specified.
2. In an apparatus for producing a current of air, the combination with a main
annular nozzle producing a diverging conical jet of water, of a secondary jet and
deflector placed within the conical jet aforesaid and producing a cloud-like mist
co-acting with the main jet to induce a current of air through the tube or passage in
which the nozzles are placed, substantially as specified.
3. A ventilating apparatus consisting of a down cast tube or passage having a
downwardly directed diverging conical jet of water therein, issuing from an annular
nozzle and playing against the sides of the tube, and a cloud-like mist produced by a
secondary jet striking against a deflector within the main jet, and an upcast tube
communicating with the downcast tube at bottom, and with the place to or from which
the current is to be conveyed, substantially as shewn and described.
4. In an apparatus for producing a current of washed and warmed air, the
combination with the water-jet apparatus placed within a down cast tube, as herein
specified, of an upeast tube, constituting also a hot water jacket, substantially as herein
described and shewn in the drawings, said jacket being in connection by circulation
pipes with a suitable heater.
5. The herein described construction of water heater for use in connection with
ventilating and warming apparatus, such as herein described, said heater consisting of
a metal tube with double walls, the annular space between being filled with water and
connected by flow and return pipes with the air heater, said water heater being
combined with and acting as a chimney for an argand gas burner, substantially as
described and shewn in the drawings.
