Lockwood, near Huddersfield, in the County of York, Overlookers, for
Sealed the 12th September 1861, and dated the 15th March 1861.
PROVISIONAL SPECIFICATION left by the said Ely Green and John
Green at the Office of the Commissioners of Patents, with their
Petition, on the 15th March 1861.
We, ELY GREEN and JOHN GREEN, of Broadfield Mill, Lockwood, near
Huddersfield, in the County of York, Overlookers, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN CARDING ENGINES," to
be as follows
This Invention relates to carding engines for carding wool or other fibrous
substances obtained from ground or torn up rags and similar fibrous materials,
technically known as "mungo" or "shoddy." The present combination and
arrangement of the parts of carding engines permit or allow portions of untorn
up rags and tufts, cotts, or locks of materials and dirt to pass from the breast
cylinder to the swift or main cylinder, which is very objectionable; to remedy.
which we place an additional stripping roller or card roller in contact with the
angle stripper, which removes such substances from the angle stripper, but not.
the fibres contained in the teeth thereof. Another card roller is placed below
clear of this roller, but in contact with the breast cylinder, which receives the.

page_text: said rags or dirt, and in conjunction with the said breast cylinder further
operate upon them.
A plain or uncovered roller is placed underneath this card roller, which acts
as a stripper thereto for removing the remainder of rags or dirt therefrom, and
another card roller is also placed in contact with the said card roller (and
also with the swift), which strips the fibre therefrom and transfers it to
the swift.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Ely Green and John Green in the Great Seal Patent
Office on the 13th September 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ELY
GREEN and JOHN GREEN, of Broadfield Mill, Lockwood, near Huddersfield, in
the County of York, Overlookers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of March, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Ely Green and John Green, Her special license that we, the said
Ely Green and John Green, our executors, administrators, and assigns,
or such others as we, the said Ely Green and John Green, our executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein ex-
pressed, 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 CARDING ENGINES," upon the
condition, amongst others, that we, the said Ely Green and John Green,
r executors or administrators, by an instrument in writing under our, or their,
or one of their hands and seals, should particularly describe and ascertain the
nature of the 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
L'etters Patent.
our
NOW KNOW YE, that we, the said Ely Green and John Green, do
hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say):-

page_text: This Invention relates to carding engines for carding wool or other fibrous
substances obtained from ground or torn up rags and similar fibrous materials,
technically known as "mungo" or "shoddy." The present combination and
arrangement of the parts of carding engines permit or allow portions of untorn
up rags and tufts, cotts, or locks of materials and dirt to pass from the breast
cylinder to the swift or main cylinder, which is very objectionable; to remedy
which we place an additional stripping roller or card roller in contact with the
angle stripper, which removes such untorn up substances and dirt from the said
angle stripper, but not the fibres contained in the teeth thereof. Another card
roller is placed below clear of this roller, but in contact with the breast cylinder,
which receives the said rags or dirt, and in conjunction with the said breast
cylinder further operate upon them.
A plain or uncovered roller is placed underneath this card roller, which acts
as a stripper thereto for removing the remainder of rags or dirt therefrom, and
another card roller is also placed in contact with the said card. roller (and
also with the swift), which strips the fibre therefrom and transfers it to
the swift.
This Invention will be readily understood by reference to the accompanying
Sheet of Drawings.
A is the breast cylinder; B, the swift or main cylinder; and C, the angle
stripper of a carding engine placed or arranged as in ordinary use. In the
using of which for carding fibrous substances obtained from torn up rags which
usually contain tufts, cotts, locks, or bits of untorn up material and dirt, such
tufts, cotts, locks, or bits are carried forward from the breast by the angle
stripper to the swift and spoil the cards thereof, to prevent which we place a
card roller D in contact with the angle stripper, which strips or removes the
said tufts, cotts, locks, or bits therefrom and precipitates them to the roller E,
which, in conjunction with the breast A, further operate upon them.
A plain
roller F removes the remainder of tufts, rags, or dirt therefrom, precipitating
the same to the floor, and a card roller G strips the fibre from the roller E and
transfers it to the swift. The direction of rotation of the several rollers and
cylinders is indicated by arrows. The surface speed of the roller D is same as
the breast stripper, and that of roller E as the breast worker; that of roller F
is rather slower than roller E; and the roller G is of the same speed as the
roller D. These rollers are driven by straps from the shaft of the breast
cylinder, but may be driven from any other convenient part of the engine.
And in carrying this Invention into practice we have found it advantageous
to place one of such rollers betwixt the middle doffer and the latter swift under
the angle stripper, which acts as a conductor, preventing the wool or other

page_text: fibrous substances from falling to the floor or being driven out by the current
of wind produced by the rapid revolution of the cylinders.
Having thus described the nature of our said Invention, and the manner
in which the same is performed or carried into effect, we would have it under-
stood that we do not claim any of the rollers or parts separately considered,
nor do we confine ourselves to the precise details of arrangement; but we claim
as of our Invention the application to carding engines of rollers in manner and
for purposes substantially as herein described and illustrated.
In witness whereof, I, the said John Green, for and on behalf of
myself and the said Ely Green, have hereunto set my hand and seal,
this Tenth day of September, One thousand eight hundred and
sixty-one.
Signed, sealed, and delivered by the
within-named John Green, in the
presence of
WM. TASKER, Patent Agent,
Halifax.
