Improvements in the Method of and Apparatus for Ventilating.
I, KENNETH WILLIAM PRIDGIN TEALE, of North Grange, Headingley, in the
City of Leeds, Cabinet Maker, do hereby declare the nature of this invention to
be as follows: :-
The object of my invention is to collect all dust and dirt on its passage through
inlet ventilators to buildings, boxes, cases, or the like.
I employ a trough or vessel in the ventilator in which is placed any suitable
liquid substance but preferably oil: from the inlet to the oil trough or vessel.
is a deflecting plate which directs the air to the oil trough so that all dirt or dust
passing with the air must impinge upon the surface of the oil or liquid contained
in the trough or vessel and is retained therein and the air is delivered into
the room free from dust or dirt.
I apply the same principle of purifying the air to boxes, specimen cases,
and other enclosures by making openings therein to admit the air required,
and making such air pass through so as to impinge upon the oil or liquid con-
tained in a suitable trough or vessel and so collect all dust and dirt contained
in the air as it passes through.

Improvements in the Method of and Apparatus for Ventilating.
I, KENNETHI WILLIAM PRIDGIN TEALE, of North Grange, Headingley, Leeds,
Cabinet Maker, 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 my invention is to collect all dust and dirt on its passage through
inlet ventilators to buildings, boxes, cases, or the like.
I employ a trough or vessel in the ventilator in which is placed any suitable
liquid substance but preferably oil; from the inlet to the oil trough or vessel
is a tube which directs the air to the oil trough so that all dirt or dust
passing with the air must impinge upon the surface of the oil or liquid contained
in the trough or vessel and is retained therein and the air is delivered into
the room free from dust or dirt.

tained in a suitable trough or vessel and so collect all dust and dirt contained
in the air as it passes through.
Figure 1 is a vertical section of a wall ventilator constructed according to
this invention and Figure 2 is an outside elevation of the same.
a is a metal plate fitting a hole through the wall and bare tubes fixed to it.
e is a trough containing oil.
The arrows show the direction of the air which is directed downwards by the
tubes onto the surface of the oil before it passes into the room. Dust and smuts
in the air are arrested on the surface of the oil and gradually sink to the
bottom..
Figure 3 shows the application of the invention to a case:
Having now particularly described and ascertained the nature, of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:.
1. The combination of a trough containing liquid with a pipe or pipes directing
the incoming air onto the surface of the liquid.
2. The employment of oil as the liquid referred to in Claim 1.
3. The method of and apparatus for ventilating substantially as described and
illustrated in the drawings.
Dated this 28th day of December 1898.
