IMPROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING WORSTED, SILK, COTTON, AND OTHER FIBRE
Year: 1872

page_text: LETTERS PATENT to William Firth, of Bradford, in the County of
York, Worsted Spinner, and Prince Smith, the younger, of Keigh-
ley, in the County aforesaid, Machine Maker, for the Invention of
"IMPROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING WORSTED,
SILK, COTTON, AND OTHER FIBRE."
Sealed the 10th December 1872, and dated the 11th June 1872.
PROVISIONAL SPECIFICATION left by the said William Firth and
Prince Smith at the Office of the Commissioners of Patents, with
their Petition, on the 11th June 1872.
We, WILLIAM FIRTH, of Bradford, in the County of York, Worsted
Spinner, and PRINCE SMITH, the younger, of Keighley, in the County
aforesaid, Machine Maker, do hereby declare the nature of the said In-
vention for "IMPROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING
WORSTED, SILK, COTTON, AND OTHER FIBRE," to be as follows:-
"
Our Invention relates to the portion of such machinery known as the
"pot eyes
or guide eyes, made of earthenware, and through which the
fibre under process of spinning or doubling passes on its way to the flyer

cap and bobbin, such eyes or guides being fixed or secured to a folding
board known as the " guide board" or top board, but it is found in
practice that guide eyes so made are liable to breakage and displacement,
causing damage to the fibre under operation, and loss of time required to
replace the eyes.
Now our improvements consist in dispensing with the aforesaid guide
eyes, and in lieu thereof we employ a strip or narrow plate of steel (or
other metal) attached to the top board by hinges. In the strip or plate
referred to are a number of holes or eyes countersunk and corresponding
in number to the number of "ends" under process of spinning or
doubling. A slit or passage from each eye to the outer edge of the strip
or plate admits the end being readily placed with the eye.
In applying the Invention to existing machinery, plates as above
described will be attached to the ordinary "folding board." Doffing is
greatly facilitated, and the guides are much more durable than those
heretofore employed and first herein referred to.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Firth and Prince Smith in the Great
Seal Patent Office on the 11th December 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, WILLIAM
FIRTH, of Bradford, in the County of York, Worsted Spinner, and
PRINCE SMITH, the younger, of Keighley, in the County aforesaid,
Machine Maker, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of June, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for. Herself, Her heirs and successors, give
and grant unto us, the said William Firth and Prince Smith, the younger,
Her special licence that we, the said William Firth and Prince Smith,
the younger, our executors, administrators, and assigns, or such others
as we, the said William Firth and Prince Smith, the younger, 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,

page_text: exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "In-
PROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING WORSTED, SILK, COTTON,
AND OTHER FIBRES," upon the condition (amongst others) that we, the
said William Firth and Prince Smith, the younger, our executors or
administrators, by an instrument in writing under our, or their, or one of
their hands and scals, should particularly describo 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 Letters Patent.
NOW KNOW YE, that we, tho said William Firth and Prince Smith,
the younger, 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 Invention relates to the portion of such machinery known as
the "pot eyes
or guide eyes, made of earthenware, and through which
the fibre under process of spinning or doubling passes on its way to the
flyer cap and bobbin, such eyes or guides being fixed or secured to a
folding board known as the "guide board" or top board, but it is found
in practice that guide eyes so made are liable to breakage and displace-
ment, causing damage to the fibre under operation, and loss of time
required to replace the eyes.
Now our improvements consist in dispensing with the aforesaid guide
eyes, and in licu thereof we employ a strip or narrow plate of steel (or
other metal) attached to the top board by hinges. In the strip or plate
referred to are a number of holes or eyes countersunk and corresponding
in number to the number of "ends" under process of spinning or
doubling. A slit or passage from each cyc to the outer edge of the
strip or plate admits the end being readily placed within the eye. In
applying this Invention to existing machinery, plates as above described
will be attached to the ordinary "folding board."
By the application and use of this Invention not only will the
breakage of pot eyes and waste of the fibrous substances under process
be prevented, but the doffing is greatly facilitated, and the guides are
much more durable than those heretofore employed and first herein
referred to.

page_text: Such being the nature of our said Invention, and the particulars of
which are so simple that the manner in which the same is to be per-
formed or carried into practical operation will be readily understood by
all spinning machinery makers and practical spinners, therefore we dcom
it unnecessary to illustrate the improvements, or to enter into any
detailed explanation thereof, but suffice it to state that we claim as our
Invention, the construction, application, and employment in lieu of
ordinary pot guides steel or other metal plates having guide eyes
formed therein in manner and for purposes substantially as herciu
described.
In witness whereof, I, the said. Prince Smith, the younger, for
and on behalf of myself and the said William Firth, have here-
unto set my hand and seal, this Ninth day of December, in the
year of our Lord One thousand eight hundred and seventy-
two.
Signed, sealed, and delivered by
the within-named Prince Smith,
the younger, in the presence of
