Year: 1874

page_text: LETTERS PATENT to Charles Parkinson, of Bolton, in the County of
Lancaster, Manager, and Robert Henry Lord, of the same Place,
Cotton Spinner, for the Invention of "CERTAIN IMPROVEMENTS IN
MACHINERY FOR CARDING COTTON AND OTHER FIBROUS SUBSTANCES.”
Scaled the 21st August 1874, and dated the 10th June 1874.
PROVISIONAL SPECIFICATION left by the said Charles Parkinson
.
and Robert Henry Lord at the Office of the Commissioners of
Patents, with their Petition, on the 10th June 1874.
WC, CHARLES PARKINSON, of Bolton, in the County of Lancaster,
Manager, and ROBERT HENRY LORD, of the same Place, Cotton Spinner,
do hereby declare the nature of the said Invention for "CERTAIN IM-
PROVEMENTS IN MACHINERY FOR CARDING COTTON AND OTHER FIBROUS SUBSTANCES,"
to be as follows:-
:-
:
Our improvements consist in the employment of two main cylinders,
which may be of the same or of different diameters. The cotton or
other fibres are fed to the first cylinder, and after the fibres, have been

page_text: partially carded between it and a series of working and clearing rollers,
or by an endless chain of top flats, or by stationary top flats, or a
combination of rollers and top flats, they are stripped off by the second
main cylinder, which overruns the first main cylinder, and which is also
provided with worker and clearer rollers, or a chain of top flats, or
stationary top flats, or a combination of the same, the fibres are then
deposited on a doffer of the ordinary description. By means of these
improvements the dirt, dust, fly, and nebs are effectually removed from
the fibres, which are completely carded and straightened before they are
deposited on the doffer.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Parkinson and Robert Henry Lord in
the Great Seal Patent Office on the 27th November 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CHARLES
PARKINSON, of Bolton, in the County of Lancaster, Manager, and
ROBERT HENRY LORD, of the same Place, Cotton Spinner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of June, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Charles Parkinson and Robert
Henry Lord, Her special licence that we, the said Charles Parkinson
and Robert Henry Lord, our executors, administrators, and assigns,
or such others as we, the said Charles Parkinson and Robert Henry
Lord, 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 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 "CERTAIN IMPROVEMENTS IN MACHINERY FOR CARDING COTTON AND OTHER
FIBROUS SUBSTANCES," upon the condition (amongst others) that we, the said
Charles Parkinson and Robert Henry Lord, our executors or adminis-.
trators, by an instrument. in writing under our, or their, or one of our

page_text: or 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 Scal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that we, the said Charles Parkinson and Robert
Henry Lord, do hereby declare the nature of our 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) :-
.
Our improvements consist in the employment of two main cylinders,
which may be of the same or of different diameters. The cotton or
other. fibres are fed to the first cylinder, and after the fibres have been
partially carded between it and a series of working and clearing rollers,
or by an endless chain of top flats, or by stationary top flats, or a
combination of rollers and top flats, they are stripped off by the second
main cylinder, which overruns the first main cylinder, and which is also
provided with worker and clearer rollers, or a chain of top flats, or
stationary top flats, or a combination of the same, the fibres are then
deposited on a doffer of the ordinary description. By means of these
improvements the dirt, dust, fly, and nebs are effectually removed from
the fibres, which are completely carded and straightened before they are
.deposited on the. doffer.
:
And in order that our Invention may be fully understood and readily
carried into operation, we will proceed to describe the accompanying
Sheet of Drawings, reference being had to the figures and letters.
marked thereon.
{
Fig. 1 is a sectional elevation of our improved machinery for
carding cotton and other fibrous substances; and Fig. 2 represents a
modification of the same.
In Fig. 1 a is the first main cylinder, and 6 the second main cylinder,
the surface of the latter running considerably faster than the former..
The cylinder a is provided with an endless chain of top flats c, and the
cylinder has a similar chain of top flats d. We wish to remark
here that instead of the chains of top flats cand d, as shown in the
Drawing, a series of working and clearing rollers or stationary top flats,

page_text: or a combination thereof; may be used. The fleece of fibres wound on
tlië lap roller e is supported by the rollers f, f; which in revolving deliver
tlie flecce to the feed rollers g, ÿ, near to which is the dirt roller h,
similar to that described in the Specification of former Letters Patent
granted to us on the Eighth day of March 1871, Number 613. The
fibres carried forward by the cylinder a are partially carded between it
and the endless chain of top flats c or their equivalents, and when they
arrive at the point of contact of the two cylinders a and b they are
stripped off the cylinder a by the cylinder b, and the fibres are finally
carded by it and the chain of top flats d or their equivalents and
deposited on the doffer i, as in ordinary carding engines. The roller j
strips the main cylinder and deposits the fibres on to the cylinder a.
In Fig. 2 the parts are arranged so as to afford greater facility in
removing the empty lap roller e and replacing a full lap. In this
arrangement the fleece is carried over the flexible apron-k and taken to
the feed rollers 7, 9. This modification of our Invention gives greater
space for the endless chain of top flats or their equivalents, and
consequently more surface for carding than the arrangement shewn in
Fig. 1. In both cases the fibres are more effectually carded and cleaned
than by the machinery hitherto in use.
Having thus stated the nature of our Invention, and described the
manner of performing the same, we wish it to be understood that we
do not limit ourselves to the details given, as they may be varied or
modified, and we claim, the combination of two main cylinders for
carding cotton and other fibrous substances, acting in the manner and
for the purpose described.
In witness whereof, we, the said Charles Parkinson and Robert
Henry Lord, have hereto set our hands and seals, this Twenty-
sixth day of November One thousand eight hundred and seventy-
