We, JOHANNIES PIETER VAN GELDER, Engineer, and PIETER VAN GELDER,
Milling Engineer, both of Bankroyd, Sowerby Bridge, in the County of York,
do hereby declare the nature of this invention to be as follows:-
This invention has for its object an improvement in apparatus or machinery
for collecting dust or other waste products of industrial establishments, known as
vortex machines, and in which the air passes tangentially into a chamber causing
the air to revolve rapidly therein, and deposit the dust or waste in a quiet portion
of the chamber.
The object of our invention is to construct and and arrange a machine or
apparatus which shall more perfectly collect the dust or waste products and at
the same time sort or grade the same, so greatly increasing their commercial
value.
We preferably employ a cylinder of a certain length placed horizontally, one
end of which is closed except a small orifice in the centre, the other end of the
cylinder is also closed excepting for a larger orifice to which an exhaust fan is-
attached.
Inside the said cylinder circular strips or segments are attached to the periphery
at short distances or intervals, and underneath and communicating with the
cylinder there is placed a trough fitted with a series of suitable outlets. The
divisions between the outlets correspond with the number of segments.
The air to be purified enters through the spiral or tangential inlet near the
closed end of the cylinder, and causes the air to rotate spirally therein, until it
reaches the other end of the cylinder, whence it is drawn away in a purified state
by the exhaust fan.
The dust or waste is deposited in the trough by means of the circular rings
attached to the inside of the cylinder in such a manner, that the heaviest products
are discharged nearest to the closed end, and spiral or tangential inlet of the
cylinder, and the finest or lightest products nearest to the exhaust fan at
the opposite end of the cylinder.
To prevent re-action in the trough or receptacles below the cylinder, we apply
a thin metal segment so placed on the inner rings, as to sufficiently cover the
trough or receptacles.
The entrance or exit of air through the dust receptacles is prevented by specially
designed valves or outlets, one below the other; the upper valve being opened by
the weight of material within the receptacle overcoming the pressure upon the
hinged flaps or sides of the valve or outlet, such material falling into the receptacle
or valve immediately underneath, this receptacle also discharges its contents in
a similar manner but both operate alternately and in such a way that when one

page_text: is opened the other is closed, for the purposes before described, the flaps or outlets
are kept closed by air pressure springs or other suitable means.
If desired the cylinder may be placed at any angle to the horizon, but so far we
have found the horizontal position to give the best results.
We are aware that this apparatus may or can be worked by pressure only
or by blast and exhaust combined, but, we prefer the exhaust only when the
machine is to be used to separate fine dust.
Further instead of one cylinder a series of cylinders of different diameters may
be coupled to form one apparatus.

Improvements in Apparatus for Separating Solid Impurities from
Air and Gases, and Sorting the same.
We, JOHANNES PIETER VAN GELDER, Engineer, and PIETER VAN GELDER,
Milling Engineer, both of 1, Bankroyd, Sowerby Bridge, in the County of York,
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 has for its object an improvement in apparatus or machinery
for collecting dust or other waste products of industrial establishments, known as
"
vortex machines, and in which the air passes tangentially into a chamber,
causing the air to revolve rapidly therein, and deposit the dust or waste in a
quiet portion of the chamber.
The object of our invention is to construct and arrange a machine or apparatus
which shall more perfectly collect the dust or waste products, and at the same time
sort or grade the same, so greatly increasing their commercial value.
DESCRIPTION OF DRAWINGS.
Fig. 1, is a side elevation in section of our improved apparatus for separating
solid impurities from air and gas, and sorting or grading the same.
Fig. 2, is a plan of our improved apparatus aforesaid.
Figs. 3 and 4 are end views of Fig. 2.
Fig. 5, is a sectional end view of valve for discharging the waste products
after collection, into suitable hoppers, or upon a suitable conveyor for removal.
Fig. 6, is an end elevation of a modification of Fig. 5.
Fig. 7, is a side elevation of Fig. 6.
We preferably employ a cylinder A of a suitable length, placed horizontally,
one end B of which may be closed, or if desired may have a small orifice in the
centre, the other end C of the cylinder is also closed excepting for a larger orifice D),
adiacent to which is fixed an exhaust fan E.
Inside the said cylinder A, circular strips, or segments F are attached to the
periphery at suitable distances or intervals apart, and underneath, and communicat-
ing with the cylinder A there is placed a trough G fitted with a series of divisions
or receptacles H. these receptacles or divisions correspond with the number of
segments F within the cylinder A.
The air or gases to be purified enters through the spiral or tangential inlet J
near the closed end B of the cylinder A; and causes the air to rotate spirally therein

page_text: until it reaches, the other end of the cylinder, whence it is drawn away in a purified
state by the exhaust fan E.
The dust or waste is deposited in the trough G or settling chamber, by means of
the circular rings or segments F, attached to the inside of the cylinder, in such a
manner, that the heaviest products are discharged nearest to the closed end B and
spiral or tangential inlet J of the cylinder, and the finest or lightest products
nearest to the exaust fan E at the opposite end of the cylinder.
To prevent reaction in the trough or receptacles below the cylinder, we apply a
thin metal segment ", so placed on the rings Fas to sufficiently cover the trough
or series of receptacles.
The entrance or exit of air up through the dust receptacles, is prevented by
specially designed valves, consisting of a longitudinal cylinder K, mounted upon a
shaft L, this cylinder is divided into sections corresponding with the number of
segments in the cylinder A, troughs M M formed upon the outer surface of the
cylinder K, receive and discharge the waste products at intervals on to an
Archimedian conveyor N, or into a series of hoppers for removal, or the conveyor N
may collect the contents of several receptables, and discharge the same into one,
two or more hoppers P for removal, flaps R of leather or other suitable material
placed upon each side and in contact with the cylinder, prevent any reaction during
such discharging.
Or in place of the cylinder K, we may construct the aforesaid valves or outlets
one below the other, the upper valve S being opened at intervals by means of a
weighted bell crank lever T, operated by tappet, cam, or finger U, this finger U
in revolving after opening the top valve, also opens the bottom valve V, discharging
the contents in a similar manner, these valves S and V are operated alternately
in such a manner that when one is opened the other is closed for the purposes
before described.
Weights W attached to the bell crank levers, close the valves immediately they
are released by the cam or finger U; a midfeather X of suitable metal arranged
within the series of receptacles, ensure the perfect discharge of the dust or other
waste products from one valve to the other.
The valves see Figs. 1, 2, 3, 4, and 5 may be operated from the driving or fan
shaft, by straps Y and pulleys Y₁, so arranged as to operate the valve spindle
slowly, or as shown at Figs. 6 and 7, the mechanism for operating the valves may
be operated by gear wheels Z from the conveyor shaft, with like result.
If desired the cylinder may be placed at any angle to the horizon, but so far we
have found the horizontal position to give the best results.
We are aware that this apparatus may or can be worked by pressure only
or by blast and exhaust combined, but we prefer the exhaust only when the
machine is to be used to separate fine dust.
Further instead of one cylinder, two or more cylinders of different diameters may
be coupled to form one apparatus.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
