Improvements in or relating to Exhaust Opening Machines for
Cleaning Cotton and other Fibrous Materials.
I, ROBERT TAYLOR, Junior, of the Soho Iron Works, Oldham, in the County
of Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
"
My invention relates to improvements in the feed trunk or pipe through which
cotton or other fibrous material is drawn from the "breaker to the "opener,
and the object of my invention is to provide a simple and efficient means for
removing the dirt and other impurities which fall from the cotton during its
passage through the trunk.
In one arrangement according to my invention I fit a revolving worm below the
grate bars and modify the construction of the trunk as required so that the dirt
and impurities falling through the bars are gradually carried by the rotation of
the worm to a discharge opening in the trunk. The dirt thus discharged may
be disposed of in any convenient manner but I prefer to employ for this purpose
a drum fitted below and close against the opening in the trunk and driven at
any convenient speed by suitable gearing; this drum has a longitudinal slot in
its periphery through which once in each of its revolutions a certain quantity
of dirt is delivered by the worm and this dirt is in its turn emptied through the
slot into any receptacle.
The grate bars might be dispensed with and the upper surface of the worm
allowed to form a substitute for the bars.
As an alternative arrangement I may employ a cylindrical trunk or pipe
arranged to be rotated in suitable bearings and instead of the ordinary grate bars
I form an internal thread or spiral of coarse pitch and of sufficient depth; the
cotton is passed through the centre of this trunk and spiral while the dirt and
other impurities dislodged fall into the spaces between the threads of the spiral and
as by their own weight they remain at the bottom of the trunk the rotation of the
latter causes the spiral to carry the impurities to one end where they can be.

COMPLETE SPECIFICATION.
Improvements in or relating to Exhaust Opening Machines for
Cleaning Cotton and other Fibrous Materials.
I, ROBERT TAYLOR, Junior, of the Soho Iron Works, 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 particularly described and
ascertained in and by the following statement:-
"
My invention relates to improvements in the feed trunk or pipe through which
cotton or other fibrous material is drawn from the "breaker" to the
opener," and
the object of my invention is to provide a simple and efficient means for removing
the dirt and other impurities which fall from the cotton during its passage
through the trunk.
In one arrangement according to my invention I fit a revolving worm below the
grate bars and modify the construction of the trunk as required so that the dirt

page_text: and impurities falling through the bars are gradually carried by the rotation of the
worm to a discharge opening in the trunk. The dirt thus discharged may be
disposed of in any convenient manner but I prefer to employ for this purpose a
drum fitted below and close against the opening in the trunk and driven at any
convenient speed by suitable gearing; this drum has a longitudinal slot in its
periphery through which once in each of its revolutions a certain quantity of dirt
is delivered by the worm and this dirt is in its turn emptied through the slot into
any receptacle.
The grate bars might be dispensed with and the upper surface of the worm
allowed to form a substitute for the bars but in practice I prefer to employ
grate bars.
As an alternative arrangement I may employ a cylindrical trunk or pipe
arranged to be rotated in suitable bearings and instead of the ordinary grate bars
I form an internal thread or spiral of coarse pitch and of sufficient depth; the
cotton is passed through the centre of this trunk and while the dirt and other
impurities dislodged fall into the spaces between the threads of the spiral and as by
their own weight they remain at the bottom of the trunk the rotation of the latter
causes the spiral to carry the impurities to one end where they can be disposed of
as above described.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying three shects of drawings reference being
had to the figures and letters marked thereon.
Figures 1, 3 and 5 are three front elevations of my improved means for removing
dirt and impurities from the trunks of an exhaust opener and Figures 2, 4 and 6
are end views respectively of Figs. 1, 3 and 5.
Similar letters refer to similar parts throughout the several views.
Referring first to the arrangement illustrated by Figs. 1 and 2, a designates
the feed pipe or trunk through which the cotton or other fibrous material is drawn
to the opener, the dust trunk, e the grids or grate bars, and d a series of division
plates or air baffles.
According to my invention as aforesaid I fit the worm e in bearings below the
grate bars c, and below the discharge opening in the dust trunk b I fit the
drum in bearings h. The worm e is driven by the band pulley i or by other
suitable means and the drum g is driven from the worm by the gears j. The
.drum g has the longitudinal slot g' in its periphery through which once in each
revolution the dirt falling through the grate bars c, and delivered at the opening b
by the rotation of the worm e is discharged into the drum g and by the latter
emptied through the slot g'.
In the second arrangement illustrated by Figs. 3 and 4 the ordinary grate bars c
are dispensed with and instead a worm or spiral thread e is formed and fitted inside
the dust trunk which in this case is cylindrical and fitted within overlapping
portions a¹ of the feed trunk a and supported upon rollers m so that it can be
rotated by the gears j, k and I, and the band pulley i secured on the axle of the
drum g.
The rotation of the trunk 6 causes the dirt and heavy impurities lying at the
bottom between the threads of the spiral e to travel along the spiral until they fall
through the opening 61 and slot g' into the rotating drum g by which they are
discharged.
In the third arrangement illustrated by Figs. 5 and 6 a further development or
modification of my invention is shown.
In this case I make both the worm e and the drum g in two parts each having a
central bearing fand respectively in addition to their end bearings. The drum g
also in this case is divided transversely into a series of compartments by means of
division plates g" corresponding in position to the division plates or air baffles d of
the dust trunk b.
One part of the worm e has a right hand and the other a left hand thread and
each part of the drum has a longitudinal slot g' as before.

page_text: In operation the dirt and impurities falling through the grate bars c enters the
drum g through the longitudinal slot g¹ the air baffles & guiding the impurities into
the several compartments of the drum. The drum g in rotating empties the
impurities on to the worm e by which they are fed to the middle and discharged
through the opening b¹.
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 :-
In an exhaust opening machine for cleaning cotton and other fibrous materials :—
1. The combination with the feed trunk, of a rotating worm for the purpose of
removing the dirt and impurities falling from the fibrous materials on their passage
through said trunk.
2. The several combinations of the feed trunk the rotating worm, and slotted
discharge drum substantially as and for the purposes herein described and as
illustrated on the accompanying drawings.
