IMPROVEMENTS IN MACHINERY FOR CLEANING COTTON
Year: 1876

page_text: LETTERS PATENT to Walter Lord, of the Firm of Messieurs Lord, Brothers,
of Todmorden, in the County of York, Machine Maker, and Leonard Kaberry,
junior, of the same Place, Mechanician, for the Invention of "IMPROVEMENTS
IN MACHINERY FOR CLEANING COTTON."
•
PROVISIONAL SPECIFICATION left by the said Walter Lord and Leonard
Kaberry at the Office of the Commissioners of Patents on the 25th August
1876.
WALTER LORD, of the Firm of Messieurs Lord, Brothers, of Todmorden, in tho
County of York, Machine Maker, and LEONARD KABERRY, junior, of the same
Place, Mechanician. "IMPROVEMENTS IN MACHINERY FOR CLEANING COTTON."
Our Invention consists in an improved combination of machinery for cleaning
cotton after it has been opened by the ordinary opener and scutcher.
Our improved machinery consists of a feeding apron supporting two or more
laps from the opener or scutcher. This apron delivers the fleece to a feed roller,
under which are the holders forming part of the self-regulating feeding apparatus
for which Letters Patent were granted to Edward Lord on the 28th day of
December, 1861, Number 3249. The cotton delivered by the feed roller is then acted
upon by two drums covered with toothed flat wire or other equivalent, and partially
surrounded with grids, as described in the Specification of Letters Patent granted to
Alexander Melville Clark on the 15th day of September, 1875, Number 3229, being
a communication from Georges Alphonse Risler, the fibres are then drawn over a
longitudinal grid or other equivalent against the surface of a perforated cylinder or
cylinders in which a partial vacuum is formed by a fan. The fleece of fibres is
then carried forward between calender rollers, and formed into a lap in the usual
manner.
In some cases a single toothed drum may be used instead of- the two above
referred to.

the said Walter Lord and Leonard Kabeiry in the Great Seal Patent Office
on the 22nd February 1877.
WALTER LORD, of the Firm of Messieurs Lord, Brothers, of Todmorden, in the
County of York, Machine Maker, and LEONARD KABERRY, junior, of the same a
Place, Mechanician "IMPROVEMENTS IN MACHINERY FOR CLEANING COTTON."
Our Invention consists in an improved combination of machinery for cleaning
cotton after it has been opened by the ordinary opener and scutcher.
Our improved machinery consists of a feeding apron supporting two or more laps
from the opener or scutcher. This apron delivers the fleece to a feed roller, under 1
which are the holders forming part of the self-regulating feeding apparatus for
which Letters Patent were granted to Edward Lord on the 28th day of December,
1861, Number 3249. The cotton delivered by the feed roller is then acted upon by two
drums covered with toothed flat wire or other equivalent, and partially surrounded
with grids, as described in the Specification of Letters Patent granted to Alexander I
Melville Clark on the 15th day of September 1875, Number 3229, being a com-
munication from Georges Alphonse Risler, the fibres are then drawn over a
longitudinal grid or other equivalent against the surface of a perforated cylinder or
cylinders in which a partial vacuum is formed by a fan. The fleece of fibres is
then carried forward between calender rollers and formed into a lap in the usual 2
manner.
In some cases a single toothed drum may be used instead of the two above
referred to.
And in order that our Invention may be fully understood and readily carried
into operation we will proceed to describe the accompanying Drawing, which' 2
represents a side elevation of our improved machinery for cleaning cotton.
a is the feeding apron supporting two or more laps b from the ordinary opener
or scutcher. This apron delivers the fleeces of fibies to the feed roller c, under
which are the holders & forming part of the self-regulating feeding apparatus
described in the Specification of Letters Patent granted to Edward Lord on the 3
28th day of December, 1861, Number 3249.
The cotton delivered by the feed roller c over the ends of the holders & is acted
upon by the drum c, which is covered with toothed flat wire or other equivalent.
The fibres are carried downwards by the drum e, while the greatest part of the dust
and other impurities is discharged through the grid f.
3
The fibres are stripped from the drum e by the drum g, which is also covered
with toothed flat wiro or other equivalent, and the dust and other impurities are
again discharged through the grid h. These drums and grids are similar to those
described in the Specification of Letters Patent granted to Alexander Melville
Clark on the 15th day of September, 1875, Number 3229, being a communication 4
from Georges Alphonse Risler.
The fibres are discharged by the drum g on to the longitudinal grid i or other
equivalent, and they are drawn against the circumferences of the perforated
cylinders j and by the partial vacuum formed therein by the fan in the
ordinary manner. The fleece of fibres thus opened and cleaned after passing 4
between the perforated cylinders j and h, is consolidated by passing between
calender rollers, and is then formed into a lap on the rollers m, m, as in the usual
lap machines. The laps are then taken to the carding engines.
In some cases only one of the toothed drums e org may be used.
By means of this improved machine the fleeces from the scutcher or opener are 5
cleared of a great proportion of their dust, seed, and other impurities, and the
fibres are prepared for the subsequent operation of carding.
Having thus stated the nature of our Invention, and described the manner of
performing the same, we declare that we claim, the combination of the machinery
known as Lord's Patent self-regulating feoding apparatus, with the toothed drums 5

page_text: and grids described in the Specification of Lotters Patent granted to Alexander
Melville Clark above referred to, and the perforated cylinders and lap machine, all
as shewn and described.
In witness whereof, I, the said Walter Lord, on behalf of myself and the said
Leonard Kaberry, junior, have hereto set my hand and scal, this Twentieth
day of February, One thousand eight hundred and seventy-seven.
