page_text: effectual cleaning of the cotton or other material to be operated upon is
obtained than has hitherto been accomplished. This we effect by
dispensing with the spiked teeth on the inside of the cover of an
ordinary willow opening or cleaning machine, and in lieu thereof
placing transverse bars set in a frame with a chamber or cavity above,
from which is taken the dust, leaf, seed, or other foreign substances from
the cotton or other material to be operated upon by means of a blast
or fan.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Greenhalgh, John Cooper, and William
Goulding in the Great Seal Patent Office on the 3rd February
1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
GREENHALGH, Machinist, JOHN COOPER, Cotton Spinner, and WILLIAM
GOULDING, Mill Manager, all of Oldham, in the County of Lancaster, 1
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of August, in the year of
our Lord One thousand cight hundred and seventy-four, in the 38th
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said John Greenhalgh, John Cooper, and William
Goulding, Her special license that we, the said John Greenhalgh, John
Cooper, and William Goulding, our executors, administrators, and
assigns, or such others as we, the said John Greenhalgh, John Cooper,
and William Goulding, our executors, administrators, or assigns,
should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should
and lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN MACHINERY FOR OPENING AND
CLEANING COTTON AND OTHER FIBROUS SUBSTANCES," upon the condition
(amongst others) that we, the said John Greenhalgh, John Cooper, and
William Goulding, our executors or administrators, by an instrument
in writing under our hands and seals, or under the hand and seal of
one of us, should particularly describe and ascertain the nature of tho a

page_text: said Invention, and in what manner the same was to be performed;
and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that we,-the-said-John-Greenhalgh, John-Cooper,
and William Goulding, do hereby declare the nature of our said Inven-
tion, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, reference
being had to the accompanying Drawings, and to the letters and figures
marked thereon, that is to say :—
Our Invention relates to that description of machinery for opening
and cleaning cotton and other fibrous substances known as the "willow"
or opener," and it consists of an "improved method of constructing the
same whereby a more effectual opening and cleaning of the cotton or
other material to be operated upon are obtained. This object we effect
by dispensing with the spiked teeth on the inside of the cover of an
ordinary "willow or opener," and substituting therefor transverse
bars set in a frame with chambers or cavities above, from which the
dust, leaf, seed, or other foreign substances from the cotton or other
material to be operated upon are conducted by means of a blast or
an or other suitable apparatus.
t
"
"
And in order that our said Invention may be fully understood, we shall
now proceed more particularly to describe the same, and for that purpose
shall refer to the several Figures on the annexed Sheet of Drawings,
the same letters of reference indicating corresponding parts in all tho
Figures.
Figure 1 of our Drawings represents a sectional elevation of a machine
constructed in accordance with our Invention; Figure 2 is a plan of the
same half, shewing the complete machine, and half with the cover or
upper part removed; and Figure 3 is a detail section of the transverse
bars drawn to an enlarged scale.

a represents the framework of the machine; b, the cylinder; c, the
fan; d, the creeper for feeding the machine; and e, the ordinary grating
surrounding the bottom of the cylinder. Surrounding the top-or-upper
part of the cylinder 6 we place transverse bars if (shewn detached-in
Figure 3). Above or outside which wo form the chambers or cavities, j'.

page_text: The shape of and distance between the bars f may be varied to suit the
class of material to be operated upon. is the door and i the creeper for
delivering the material from the machine, and are the feed rollers;
Z are the spikes or teeth which are disposed on the cylinder b, and which
we arrange by preference so that one set of spikes or teeth will break
joint with or not be in the same line as the two adjacent sets as shown
in Figure 2, whereby the action of the spikes or teeth is equally dis-
tributed over the inner surface of the bars f; m is a dust pipe or tube
connecting the chambers or cavities 9, g', above the bars, and n is a
spout or channel for carrying off the dust or other refuse.
The machine operates in the following manner, viz. :-The cylinder b
is made to revolve at the usual or any required or desirable speed. The
cotton or other substance or material to be operated upon being placed on
tho crceper d is passed into the machine between the rollers k, and comes
in contact with the spikes or teeth fixed on the cylinder, the grating e
surrounding the under side of the cylinder, and the bars f surrounding
the upper side of cylinder. The sceds and heavier particles disconnected
from the material fall through the grating into the lower part of the
machine in the usual manner, and the dust, leaf, and other lighter sub-
stances pass between the bars f placed round the upper part of the
machine, enter the chambers or cavities 9, 9, above, whence they are
withdrawn by the ordinary blast or fan c, or by any other suitable
apparatus for causing a current of air, as may be found most desirable,
and conveyed into the ordinary dust hole or other convenient receptacle
through the spout or channel n as indicated by the arrow.
In the Drawing the apparatus is shown as arranged for the dust to bo
drawn through the fan, but it may be driven from it and conveyed away
at any suitable part, either by a fan or other means.
The machine as illustrated in the Drawing delivers the cotton at tho
front on to a cross lattice or creeper i, so as to fall or be delivered at
the side, but it may be constructed or altered to deliver at the back or
elsewhere, as may be found most convenient.
Having now described and particularly ascertained the naturo of
our said Invention and the manner in which the same is or may be used
or carried into effect, we would observe in conclusion that what wo

page_text: consider to be novel and original and therefore claim as the Invention
secured to us by the herein-before in part recited Letters Patent is,-
First. The application and use to and in the machines known as the
"willow "
or "opener" of bars placed transversely over or around the
top or upper part of the cylinder, substantially-as-and-for-the-purpose
herein-before described and as illustrated by our Drawings.
Second. The combination with the before-mentioned transverse bars
of chambers or cavities above the same, substantially as and for the
purpose herein-before described and as illustrated by our Drawings.
In witness whereof, we, the said John Greenhalgh, John Cooper,
and William Goulding, have to this our Specification set our
hands and seals, the Twenty-eighth day of January, One thousand
eight hundred and seventy-five.
