PROVISIONAL SPECIFICATION.
Improvements in Machines for Opening and Cleaning Cotton and
other Fibres.
I, ROBERT TAYLOR, Junior, of the firm of Asa Lees and Company Limited,
of Oldham, in the County of Lancaster, Engineer, do hereby declare the nature
of this invention to be as follows:-
:-
My invention is particularly applicable to exhaust openers and similar machines
in which the cotton or fibre to be cleaned passes through the fan or fans employed
to blow or draw the fibre on to the perforated cages the object of my invention
being to assist the work of the beating cylinders.
In carrying my invention into effect I place a grid or grids extending round any
portion of the vanes of the fan and in close proximity to them, the grid being
surrounded by the usual fan casing; in this way the revolving fan aided by the
grid acts as a beater and knocks some of the dust and impuritics into the space
between the grid and the fan casings.
The dirt can be removed in any convenient manner through suitable doors in the
casing or it may fall on to the usual grid in the trunk placed between the fan and
the cages.
.
Either alone or in addition to the grid which surrounds a portion of the fan a
grid or grids may be arranged on one or both sides of the fan.
In place of the grids the casing of the fans could be roughened or corrugated
so as to form a rough surface against which the cotton would be beaten to loosen
the dirt.

COMPLETE SPECIFICATION.
Improvements in Machines for Opening and Cleaning Cotton and
other Fibres.
I, ROBERT TAYLOR, Junior, of the firm of Asa Lees and Company Limited,
of Oldham, 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 par-
ticularly described and ascertained in and by the following statement :-
My invention is particularly applicable to exhaust openers and similar machines
in which the cotton or fibre to be cleaned passes through the fan or fans employed
to blow or draw the fibre on to the perforated cages the object of my invention
being to assist the work of the beating cylinders.
In carrying my invention into effect I place a grid or grids extending round any
portion of the vanes of the fan and in close proximity to them, the grid being
surrounded by an airtight casing; in this way the revolving fan aided by the grid
acts as a beater and knocks some of the dust and impurities into the space between
the grid and the casings.
The dirt can be removed in any convenient manner through suitable doors in
the casing.
Either alone or in addition to the grid which surrounds a portion of the fan a
grid or grids may be arranged on one or both sides of the fan.
In place of the grids the casing of the fans could be roughened or corrugated
50 as to form a rough surface against which the cotton would be beaten to loosen
the dirt.

page_text: And in order that my invention may be fully understood and readily carried
into effect I will describe the accompanying sheet of drawings reference being had
to the figures and letters marked thereon.
Fig. 1 is an end view and Fig. 2 a side view with part of the casing removed,
of so much of an opening machine as is necessary for the illustration of my inven-
tion and
Figs. 3 and 4 are similar views to Figs. 1 and 2 and illustrate the application of
grids or slotted sides to the fan casing.
Similar letters refer to similar parts throughout the several views.
In the drawings, a is the frame of the machine on which are secured bearings a¹
for the fan b in this case made with a central disc b¹ to strengthen the vanes 6³;
the casing c of the fan is partially cut away as shown in Fig. 2 and its place taken
by a grid d. This grid d is enclosed in front by an airtight casing e which receives
dirt &c., and is provided with a door e¹. The cages are connected as usual by a
trunk with an ordinary grid g.
In Figs. 3 and 4 the fan casing c is also partially cut away as in Figs. 1 and 2
but to a greater extent. The sides c' of the fan casing are arranged with open slots
to form a grid both sides being covered with a special casing / provided with
doors and supported on the frame a.
The cotton or other fibre is fed to the machine through a pipe and side
trunks jj which conduct it to both sides of the fan the blades of which beat it
against the grid d and a certain amount of dirt or other impurities is driven
through the grid and falls into the airtight casing e from which it can be removed
through the door e', the bulk of the cotton passes as usual over a grid in the
trunk g to the cages from which the air is exhausted by a fan k, the remaining
portions of the machine call for no special notice as they may be of any suitable
form.
In Figs. 3 and 4 the only point of difference is that the cotton while passing
through the fan b is beaten against the slotted sides c' of the fan casing and some
of the dirt &c., is knocked out of it and falls into the side chambers and a further
portion of dirt may be loosened from the fibre and passes out of the grid d into
the airtight casing e.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. Substituting a grating such as the grid d for the ordinary fan casing in an
opening machine substantially as herein described with reference to Figs. 1 and 2.
2. The combination with a fan or fans of an opening machine, of side slots or
grids in the sides of the fan casing substantially as herein described with reference
to Figs. 3 and 4.
3. The general combination and arrangement of parts embodying my improve-
ments in machines for opening and cleaning fibrous materials substantially as herein
shown and described.
