We JOHN GREENHALGH, RICHARD GREENHALGH, and JOSIAH GREENHALGH, all of
Vulcan Iron Works, Oldham in the County of Lancaster, Machinists, do hereby-
declare the nature of the invention to be as follows:-
-
Our invention relates to improvements in machines for opening and cleaning cotton
or other fibres, and has for its object in the first place, to provide means whereby the
fibres to be treated can be introduced or fed into the machine (viz., between the grid
and cylinder) automatically) instead of by hand, thus saving a great deal of time and
ensuring more regular and better work.
Secondly, to utilize the air which issues from the machine on delivery of the
treated fibres, for the purpose of further cleaning the same, and freeing the travelling
delivery band or table from dirt or any other foreign matter which may still be
contained in the fibres, and deposits itself on the said delivery table or band.
The first part of our invention consists in providing the grid onto which the fibres
to be treated are fed, and to which an intermittent radial movement is imparted by
suitable means,
with a trough or shoot.
This trough or shoot is attached to the upper end of the grid frame and is also
made radially movable, in such a manner, that on the upper end of the grid frame
descending, the free or outer edge of the trough or shoot is ascending, thus
throwing the fibres deposited thereon, into the machine onto the said grid.
This we attain by hinging the said trough or shoot to the upper end of the grid frame,
and attaching to each end on the outer edge of the trough or shoot, a cord, or
equivalent, arranged to ride over a pulley, the other end of the said cord or equivalent,
being connected to the upper end of the grid frame.
The second part of our invention consists in forming below the delivery band
or table, and above the described feeding device, a hopper of suitable shape and
material, in order to cause the air issuing on delivery of the fibres, onto the said band
or table, to deflect downwards, through the latter and into the said hopper for the
purpose of further cleaning the treated fibres, and freeing the delivery table or band
from dirt or any other foreign matter which may have collected thereon.

Improvements in Machines for Opening and Cleaning Cotton and
other Fibres.
We JOHN GREENHALCH, RICHARD GREENHALGH, and JOSIAH GREENHALGH, all
of Vulcan Iron Works Oldham in the County of Lancashire, Machinists 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:
Our invention relates to improvements in machines for opening and cleaning cotton
or other fibres, and has for its object in the first place, to provide means whereby the
fibres to be treated can be introduced or fed into the machine (viz. between the grid
or flake & cylinder) automatically) instead of by hand, thus saving a great deal of time
and securing more regular and better work.
Secondly, to utilize the air which issues from the machine on delivery of the treated
fibres, for the purpose of further cleaning the same and freeing the travelling delivery
band, table or creeper from dirt or any other foreign matter which may still be con-
tained in the fibres and deposits itself on the said delivery table, band, or creeper.
And in order that our invention may be more fully understood we have caused to
be appended hereunto one sheet of drawings which shows a vertical cross section of
that part of the machine to which our improvements are applied a is the frame part,
6 the delivery door, c the grid or flake, d the delivery table, band or creeper and ethe
cylinder of the machine.
In carrying out this invention the first part of our improvements consists in pro-
viding the grid or flake c onto which the fibres to be treated have been fed heretofore
by hand, and to which an intermittent radial movement is imparted by suitable means
from any moving part of the machine, with a trough, shoot, or tray f
This trough, shoot or tray f which we attach preferably to the upper end of the
grid or flake frame c', is made radially movable in such a manner that on the upper
end of the grid frame e descending, the free or outer edge of the trough, shoot, or
tray is ascending, thus throwing the fibres previously deposited thereon, into the
machine onto the said grid or flake c automatically.
This we attain preferably by hinging the said trough, shoot, or tray f to the
upper end of the grid frame c' so as to form a double joint c², and attaching
to each end near the outer edge of the trough, shoot, or tray f, by means of
studs, a cord or band g or its equivalent, arranged to ride over a pulley y' mounted
on a cross shaft g and carrier pulley g³, rotating on brackets gt bolted to the side
frame work a of the machine, the other end of the said cord g or equivalent, being
suitably connected to the upper end of the grid or flake frame c¹.
On the cross shaft g being intermittently actuated by suitable means the pulley g
causes the grid or flake e by reason of the hinged connection c², to descend and the
trough, shoot or tray to ascend into the position indicated in dotted lines, thus
throwing the substance to be treated onto the grid or flake c into the machine.

page_text: In carrying out the second part of our invention the improvements consist in
forming below the delivery band, table, or creeper d, and above the described feeding
device (viz., trough shoot or tray f) a hopper h of suitable shape and material, in
order to cause the air issuing on delivery of the fibres onto the said delivery band,
table or creeper d to deflect downwards, through the latter and into the said hopper h,
& through the opening into the machine, thus causing a circulation of the air for
the purpose of further cleaning the treated fibres, and freeing the delivery table,
band or creeper d from dirt or any other foreign matter which may have collected
thereon.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what
we claim is :-
In machines for opening and cleaning cotton and other fibres :-
1st. The employment of a trough shoot, or tray factuated from the grid or flake c,
substantially as & for the purpose specified.
2nd. The employment of a hopper h underneath the delivery table, band or
creeper & substantially as and for the purpose specified.
