PROVISIONAL SPECIFICATION.
Improved Means or Apparatus for Purifying, Ozonising, and Cooling
Air for Ventilation.
I, MORRIS PAUL HATSCHEK of Ashley House, Albert Bridge Road, Belfast,
in the County of Down, Chemical Engineer, do hereby declare the nature of my
said invention to be as follows:-
This invention is an improvement or addition to my Patent No. 3574, dated
26th of November 1889.
My invention refers to my description of Patent on "An improved system of
Pnuematic Malting" delivered under No. 3574 on the 26th November 1889, and
constitutes a further improvement of the same and especially of the air-washing
apparatus drawn and described there and in the application of this apparatus and
its modifications for various purposes.
The cylinder A forming the said air-washing apparatus can be substituted by a
square column or chamber &c., and made of iron or brickwork, of wood, earthen-
Instead of the taps,
ware or any other fit material shaped in a suitable manner.
protected by shades, indicated in the said drawing for the entrance of atmospheric
air, the apparatus (cylinder &c.) can be provided inside with perforated plates,
arranged in steps, or with perforated bricks, allowing the air and the water to be
brought into contact on large surfaces, or with pieces of coke, pumice-stone or other
porous or perforated material, serving the same purpose.
In case of very low temperature being required, the apparatus can be partly filled
with pieces of ice also, or ice can be added to the water, destined for cooling the
atmospheric air.
The ozonising of the air can be effected either when entering or when leaving the
washing apparatus, the same might be constructed in one or the other manner, as
described.
The fan or blower can drive the air into the washing-apparatus, or suck it from
the same, as one or the other disposition might be found more convenient.
The same system of driving or sucking the atmospheric air through the aforesaid
washing and ozonising apparatus with its various modifications and delivering it
afterwards by main- and distributing-pipes is to be used as well for the ventilation of
floor-maltings, so as to have the growing process carried on in a sound and properly
tempered atmosphere and the carbonic acid gas and other impurities, floating in the
air, continually removed: for the ventilation of fermenting rooms (tun-rooms) of
breweries, distilleries, etc., to the same purpose, and especially to avoid infection
of the wort or wash, and of the yeast formed therein: further for the ventilation of
dwelling-houses, hotels, restaurants, theatres and all such places, where unsound or
infected air of any kind (with fog, smoke, dust, nitrogen, carbonic acid etc.) should
be removed and substituted by sound and purified air of a suitable temperature for
the benefit of the inhabitants, visitors and other persons, staying in such localities
of any description whatever.
The fans or blowers used can be connected with steam or gas or hot air engines
etc., but when driven by water-motors, the water leaving the latter, can be employed
afterwards for washing the air, thus serving a double purpose.

Improved Means or Apparatus for Purifying, Ozonising, and Cooling
Air for Ventilation.
I, MORRIS PAUL HATSCHEK, formerly of Ashley House, Albert Bridge Road,
in the County Down, but now residing at 27 Bedford Place, London W.C.,
Chemical Engineer, do hereby declare the nature of my said 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 relates to a certain invention for which I have obtained Letters
Patent dated 26th November 1889, No. 3574; and the object of my present inven-
tion is to make further improvements in or additions to the same, and especially to
improve the air-washing apparatus therein described, and to extend the application
of the same system and apparatus, and its modifications to various other useful
purposes.
In my said former Specification No. 357480, the principal part of the air-washing
apparatus consists of a cylindrical vessel. This vessel or chamber or its equivalent
may be formed rectangular or otherwise, and made of iron, brickwork, wood,
earthenware, or any other suitable material.
I fit the chamber, forming the air-washing apparatus, with a series of perforated
plates, or perforated bricks or tiles, which allow the air and water to be brought
into contact, on large surfaces. Or pieces of coke, pumice stone, or other porous
or perforated material may be used for the same purpose.
In case of very low temperatures being required, the apparatus can be partly
filled with ice, or water cooled by ice may be run through the same to cool the
air to lower degrees.
The ozonising of the air may be effected by electric currents or otherwise, either
while entering or leaving the apparatus.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.

The water from the chamber h falls down in the form of rain, and is run off by
the pipe d. The air at the same time passes upwards and escapes by the pipe i,
circulating in its passage between the plates bb, and washed by the falling water.
k is a chamber, fitted to the pipe i, intended to contain sticks of phosphorus lying
in water; or permanganate of soda and sulphuric acid for developing ozone; or a
porous material impregnated with other means for disinfecting the passing air.
The air may be driven through the apparatus either by pressure or exhaustion,
whichever may be found most convenient. Or instead of a fan or blower, Körting's
water spray ventilator or another similar system may be used for inducing a current
of air through the apparatus and driving it through leading pipes at the same time;
especially in cases where only small quantities of air are required.
The same system of driving or exhausting the atmospheric air, through the afore-
said washing and ozonising apparatus, with its various modifications, and delivering
it by main pipes, and distributing pipes formed with a number of perforations for

page_text: distributing the air as required, may be used for the ventilation of floor maltings,
so as to have the growing process carried on in a sound and properly tempered
atmosphere as well in the colder as in the warmer season, in which latter floor
malting is generally stopped for periods of 3 or 4 months, and the carbonic acid gas
and other impurities floating in the air, are thereby continually removed. Also for
the ventilation of fermenting rooms (tun rooms) in breweries, distilleries &c., for
the same purpose; and especially to avoid infection of the wort or wash, and of the
yeast formed thereon. Also for ventilating dwelling-houses, hotels, restaurants,
theatres, concert rooms, and all such places where vitiated air of any description
(with fog, smoke, dust, nitrogen, carbonic acid gas &c.) is required to be removed,
and substituted by sound and purified air of a suitable temperature for the benefit of
the inhabitants, audiences, or visitors. The purified air can, after leaving the
washing apparatus, be passed through a heating apparatus; various constructions
of which are well known in all cases where ventilating with tempered air is
required.
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 :-
1. The method of preparing purified and ozonised air for floor maltings, tun
rooms, dwelling houses and other buildings, by means of washing and other apparatus
substantially as hereinbefore described and illustrated by the drawings.
2. The manufacture and use of air washing and ozonising apparatus, constructed,
arranged, and operating substantially as hereinbefore described and illustrated by
the drawings.
3. The application and use of apparatus as aforesaid for the production of pure
green malt free from infection, at all times of the year, by means of cooled, purified
and ozonised air, substantially as described.
