Improvements in or Appertaining to Stive Rooms and in
Apparatus for Collecting and Discharging the Dust or Stive.
We, JAMES HIGGINBOTTOM and ORSINI STUART of the Firm of Higginbottom and
Stuart of 51 Seel Street, in the City of Liverpool, Milling Engineers, do hereby
declare the nature of this invention to be as follows:-
This invention consists in the application of improvements to the stive room or
dust collecting chambers as originally devised by Monsieur Perrigault in France.
The stive room is divided by partitions or floors into a long serpentine chamber
formed with horizontal trays on the floors, upon which the dust is deposited by
gravity as the dust laden air is passing over the same.
In our stive rooms we arrange-firstly, the trays, preferably as endless revolving
belts, and employ automatic collecting apparatus, preferably transverse worms at the
ends of the belts worked by suitable gearing, to continuously remove the deposited
dust, secondly-deflecting boards to each tray for the purpose of making a contraction
of the cross sectional area of the air passage as it enters to the tray, and for the
purpose of allowing the air passage to again increase in area as the air travels over
the surface of the tray, and for the purpose of forming a dead chamber over the tray
and thereby increasing the depositing capacity of the tray surfaces, thirdly, we arrange
an air tight collecting box or boxes at one side to receive the collected dust from each
tray and to discharge the same automatically on the exterior of the stive room.
Fourthly, we form the collecting box so that the driving arrangement to the
automatic apparatus is enclosed therein, or else box off a special small chamber for the
driving apparatus.

Apparatus for Collecting and Discharging the Dust or Stive.
We, JAMES HIGGINBOTTOM and ORSINI STUART of the Firm of Higginbottom
and Stuart of 51 Seel Street in the City of Liverpool, Milling Engineers, 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 consists in the application of improvements to the stive room or dust
collecting chambers as originally devised by Monsieur Perrigault in France.
The invention may be best described by reference to the accompanying drawings
in which
Figure 1 is a longitudinal section,
Figure 2 a transverse section and
Figure 3 a sectional plan of our improved stive room, with collecting and discharging
apparatus.
The stive room A is divided longitudinally into two chambers, a large one A¹ and
a small one A2. The dust or stive is collected in the large one A' and the gearing
for driving the apparatus is contained in the small one A2, though if preferred the
smaller chamber may be dispensed with and the driving arrangement enclosed in the
larger one, or placed in part outside the building. The dust laden air enters
the chamber A at a, and passes out at a¹, being compelled to take a serpentine
course (as shown by the arrows in Figure 1) by the horizontal trays B, which are
the full width of the chamber, but somewhat shorter than it, and are so arranged that
the free ends of any two adjacent trays are at opposite ends of the chamber. The
dust is deposited by gravity on the trays B, as the dust laden air is passing over the
same. If preferred, the trays instead of being fixed, as shown in the drawings, may
be in the form of endless revolving belts.
The dust is collected at one end of each tray by a scraper or scrapers C, attached
to endless chains or bands C, said bands being carried by wheels C² on shafts C³ & C
These shafts are supported in bearings in the sides of the chamber, the shafts C³
passing through into the chamber A², and being provided with spur wheels C³, by
which the scrapers are actuated, as will hereafter be described. The bearings of the
shafts Care adjustable as shown at Co.
The dust is discharged from the trays into the chute D, preferably by transverse
worms E, placed one at the end of each tray. The worm shafts project into the
chamber A & are each provided with a band wheel E¹, by which they are driven,
and a pinion E2 which gears with the spurwheel C and actuates the scrapers C.
Bands F pass from each of the wheels E¹ to similar bandwheels G, which are mounted
on the driving shaft G'.
It will thus be seen that the whole apparatus is worked automatically from the
shaft G', and that the dust is collected in the chamber A¹and discharged automatically
on the exterior of the stive room by chute D.

page_text: Deflecting boards H are attached to the free end of each tray for the purpose of
making a contraction of the cross sectional area of the air passage as it enters to the
tray, and for the purpose of allowing the air passage to again increase in area as the
air travels over the surface of the tray, and for the purpose of forming a dead chamber
over the tray, and thereby increasing the depositing capacity of the tray surfaces.
I is a revolving cowl for preventing the outside air from blowing down into the
stive room.
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 :
1. The combination of stive room with horizontal trays on which the dust is
deposited by gravity, travelling scrapers for collecting the dust, and transverse worms
or their equivalent for discharging the same at the exterior of the stive room, the
whole worked automatically & substantially as described and shown.
2. In combination with the trays B, (whether fixed or travelling,), having air
passages so arranged as to cause the air to pass over each in succession, a deflecting
board H at the entrance of the air to each tray, whereby the air is caused to expand
as it enters the space above each tray, and a stagnation of the air is caused immediately
over each tray, through which the dust from the weakened expanding current can
settle.
3. A stive room, collecting and discharging apparatus, constructed as a whole
substantially as herein described and shown."
