We, THOMAS WILLIAM BASSETT MUMFORD of 1 Glendale Villas, Sylvan Road
Winstead in the County of Essex Chemist and ROBERT MOODIF of 19 Khedive Road
Forest Gate in the County of Essex, Engineer do hereby declare the nature of this
Invention to be as follows
The object of this Invention is to provide an apparatus of a very simple and
economical construction which will efhciently separ ite dust or other particles from air
An apparatus constructed according to this Invention consists of casing with which
is combined or in which is situated a device such as evolving fan for inducing a
current of air and into this casing also opens an inlet duct leading from the exterior
and opening near to the centre or eye of the fan and also an outlet duct leading from
near to the periphery of the fan, to the exterior of the casing As the fan revolves
air is drawn into the casing through the inlet duct and is received by the fan by
which centrifugal force is imparted to it and the particles which it contains the said
particles being projected outwards and falling into the casing whilst the purified air
passes into and out from the outlet duct Surrounding the upper part of the air
outlet duct there may be guards or louvres which prevent or assist in preventing
particles from entering the air outlet duct

We THOMAS WILLIAM BASSETT MUMFORD of 1 Glendale Villas Sylvan Road
Wanstead in the County of Essex Chemist and ROBERT MOODIE of 19 Khedive
Rond Forest Gate in the County of Essex Engineer do hereby declaro the nature
of this Invention and in whit manner the same is to be performed to be particularly
described and ascertained in and by the following statement
1
The object of this Invention is to provide an apparatus of a very simple and
economical construction which will efficiently separate dust or other particles from
air
An apparatus constructed according to this Invention is shown in vertical
section in the accompanying drawing It consists of an outer casing A in which is
situated a device D such as a revolving fan for inducing a current of air and into
this casing opens an inlet duct leading from the exterior of the casing A and
opening near to the centre or eye of the fan D and into the said casing there passes
an outlet duct B leading from near to the periphery of the fan D and opening at the
exterior of the casing A As the fan D revolves air is drawn into the casing through
the inlet duct C as shown by the arrows a and is received at the eye of the fan by
which fan contrifugal force is imparted to it and the particles which it contains the
said particles being projected outwards between the blades of the fan and falling into
the cising A as shewn by the arrows y whilst the purified air passes into and out
from the outlet duct as shewn by the arrows 2 Surrounding the upper part of the
air outlet duct there may be guard plate d attached to the fan D as shewn in dotted
lines which prevents or assists in preventing particles from entering the air outlet
duct B
Having now particularly described and ascertained the nature of our said Inven-
Lion and in what manner the same is to be performed we declare that what we
claim is —
1st The arrangement or combination of parts constituting the apparatus for
separating dust or particles from air substantially as hereinbefore described and
illustrated in the accompanying drawing whether or not the shield & be employed
2nd In apparatus for separating dust or particles from air the combination of an
outer casing containing a fan, an air inlet leading from outside the said casing
to the eye of the said fan and an air outlet leading from the upper part of the space
clear of which the particles are propelled by the action of the said fan and opening
outside the said casing all substantially as hereinbetore described
