I, HENRY SIMON of No. 20 Mount Street Manchester in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows :-
In middlings purifiers a current of air is drawn or forced in and has to pass through
the middlings. When this air is impure, as it often is, especially in or near manu-
facturing towns, loaded with particles of soot, it is apt to deposit many of these
impurities on the material under treatment, and thereby greatly to depreciate its
quality and value. Now according to my invention, in the passage by which air is
admitted to the purifier, I place a screen or several screens of porous fabric or of
granules loosely arranged, in passing through which the air deposits the impure
particles without carrying them with it to vitiate the material operated on by the
by the purifier.
When a number of purifiers are arranged in one apartment, the air supplying the
apartment may be thus purified so as to supply all the purifiers in the apartment with
filtered air. Obviously, instead of stationary filters, dust catchers of any known kind
may be employed to remove more or less of the impurities from the air.

An Improvement in Middlings Purifiers.
I, HENRY SIMON of No. 20 Mount Street Manchester in the County of Lancaster,
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 :-
In middlings purifiers, a current of air is drawn or forced in and has to pass
through the middlings. When this air is impure, as it often is, especially in or near
manufacturing towns, loaded with particles of soot, it is apt to deposit many of these
impurities on the material under treatment, and thereby greatly to depreciate its
quality and value. Now, according to my invention, in the passage by which air is
admitted to the purifier I place a screen or several screens of porous fabric or of
granules loosely arranged, in passing through which the air deposits the impure
particles without carrying them with it to vitiate the material operated on by the
purifier.
When a number of purifiers are arranged in one apartment, the air supplying the
apartment may be thus purified so as to supply all the purifiers in the apartment with
filtered air. Obviously instead of stationary filters, dust catchers of any known kind
may be employed to remove more or less of the impurities from the air.
As an example of the application of my invention, I shew in the accompanying
drawing a vertical transverse section of a purifier provided with means according to
my invention for purifying the air drawn in from the surrounding atmosphere.
A A are inclined porous screens fixed in the lower part of the framing and covering
the only passage by which the external air can enter the interior of the purifier.
Within the screens A are fixed inclined deflectors B for distributing the currents of
air which pass through the screens and through the intervals between the deflectors as
indicated by the arrows. The screens A may be made removeable, so that they can be
taken away from time to time to be cleaned, or they may be kept clean in their places
by any known suitable cleansing apparatus arranged to act on them. For purifiers of
other forms, screens similar to those shewn at A may be arranged at the air inlets of
each purifier, or, when there are a number of purifiers in one apartment, all the inlets
for air to that apartment may be provided with similar screens.
Having now particularly described and ascertained the nature of my invention and
in what manner the same is to be performed, I declare that what 1 claim is :-
==
Providing the inlets for air drawn into middlings purifiers with porous screens or
their equivalents, substantially as and for the purpose set forth.
