CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING AND SPINNING COTTON AND OTHER FIBROUS MATERIALS
Year: 1853

page_text: LETTERS PATENT to Henry Spencer, Manager, Henry Tattersall,
Mechanic, and Hugh Simphson, Carder, all of Rochdale, in the
County of Lancaster, for the Invention of "CERTAIN IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR PREPARING AND SPINNING COTTON
AND OTHER FIBROUS MATERIALS."
Sealed the 1st October 1853, and dated the 1st April 1853.
PROVISIONAL SPECIFICATION left by the said Henry Spencer,
Henry Tattersall, and Hugh Simphson, at the Office of the Com-
missioners of Patents, with their Petition, on the 1st April 1853.
We, HENRY SPENCER, Manager, HENRY TATTERSALL, Mechanic, and
HUGH SIMPHSON, Carder, all of Rochdale, in the County of Lancaster,
do hereby declare the nature of the said Invention of "CERTAIN IM-
PROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING AND SPINNING
COTTON AND OTHER FIBROUS MATERIALS" to be as follows:-
Our improvements apply, first, to "carding engines;" and, secondly,
to machines for spinning, called "throstles."
The first part of our improvements consists of a plate or plates of the
same construction as the ordinary "doffing plates" now in use in carding

page_text: engines. The said plate or plates are to be placed or fixed stationary in a
central position, near to the "taker" or "licker in;" that is, the roller or
rollers which operate in feeding in the cotton to the engine. In the
"throstle" our improvements apply, first, to the spindle, and consist of
a loose collar or bolster, to be adapted to the same. The said loose
collar works by friction of contact with the spindle, and in consequence
of the bobbin having an oscillating position in the washer cloth, we are
enabled to run the spindles at a much higher velocity than heretofore;
and the bobbins will also wear for a much longer period than has
hitherto been the case.
The second part of our improvements in the "throstle" applies to
the "tin roller" which is employed to drive the series of spindles, and
consists in covering the surface of the said roller with cloth or other
substance, which will have the effect of preventing the spindle bands
from slipping upon the said surface, and thus impart a much more even
and uniform twist to the yarn than can be produced with the bands
running upon the polished surface of the drum as heretofore.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Spencer, Henry Tattersall, and Hugh
Simphson, in the Great Seal Patent Office, on the 1st October
1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we,
HENRY SPENCER, Manager, HENRY TATTERSALL, Mechanic, and HUGH
SIMPHSON, Carder, all of Rochdale, in the County of Lancaster, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of April, in the year of
our Lord One thousand eight hundred and fifty-three, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Henry Spencer, Henry Tattersall,
and Hugh Simphson, Her especial licence, that we, the said Henry
Spencer, Henry Tattersall, and Hugh Simphson, our executors, admi-
nistrators, and assigns, or such others as we, the said Henry Spencer,

page_text: Henry Tattersall, and Hugh Simphson, 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 MA-
CHINERY OR APPARATUS FOR PREPARING AND SPINNING COTTON AND OTHER
FIBROUS MATERIALS," upon the condition (amongst others) that we, the
said Henry Spencer, Henry Tattersall, and Hugh Simphson, or one of
us, by an instrument in writing under our hands and seals, or under
the hand and seal of one of us, should particularly describe and ascer-
tain the nature of our 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 I, the said Henry Spencer, 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 apply, first, to "carding engines;" and, secondly,
to machines for spinning, called "throstles." The first part of our im-
provements consists of a plate or plates having a serrated edge of the
same construction as the ordinary "doffing comb" now in use in card-
ing engines, the teeth of which being somewhat similar to those of the
"Licker in"
Roller
doffing comb. The said plate or plates are
or
to be placed or fixed stationary in a nearly
central position, near to the "taker"
"licker in;" that is, the roller or rollers which
operate in feeding in the cotton to the engine,
and placed longitudinally immediately under-
neath such roller, as shewn in the margin of
these Presents, the object being to regulate
and assist in straightening the cotton as it is
fed into the engine, as well as to arrest a considerable portion of the
dirt, and prevent much extraneous matter entering upon the main
Combs

page_text: cylinder. In the throstle our improvements apply, first, to the spindle, and
consist of a loose collar or bolster, to be adapted to the same in place of
the ordinary bolster, which has hitherto been invariably fast in the bolster
rail. The said loose bolster works by friction of contact with the spindle,
and in consequence of the diminution of the friction, we are enabled to run
the spindles at a much higher velocity than heretofore; and the bobbins
will also wear for a much longer period than has hitherto been the
case. The second part of our improvements in the "throstle" applies
to the "tin roller" which is employed to drive the series of spindles,
and consists in covering the surface of the said roller with cloth or
other substance, which will have the effect of preventing the spindle
bands from slipping upon the said surface, and thus impart a much
more even and uniform twist to the yarn than can be produced with
the bands running upon the polished surface of the drum as heretofore;
or, if preferred, narrow strips or fillets of such covering may be placed
under each spindle band. Which three several improvements in ma-
chinery or apparatus for preparing and spinning cotton and other fibrous
materials, as above particularly described and set forth, we claim as of
our Invention.
In witness whereof, I, the said Henry Spencer, have hereunto
set my hand and seal, the Thirtieth day of September, in
the year of our Lord One thousand eight hundred and fifty-
three.
