Year: 1858

page_text: LETTERS PATENT to Benjamin Foster, of Denholme, near Bradford, in
the County of York, Spinner, and Prince Smith, of Keighley, in the
County of York, Machinist, for the Invention of "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR SPINNING AND DOUBLING WOOL, ALPACA,
MOHAIR, COTTON, SILK, FLAX, AND OTHER FIBROUS SUBSTANCES."
Sealed the 21st April 1859, and dated the 28th October 1858.
PROVISIONAL SPECIFICATION left by the said Benjamin Foster and
Prince Smith at the Office of the Commissioners of Patents, with their
Petition, on the 28th October 1858.
We, BENJAMIN FOSTER, of Denholme, near Bradford, in the County of
York, Spinner, and PRINCE SMITH, of Keighley, in the County of York,
Machinist, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR SPINNING AND DOUBLING WOOL, ALPACA,
MOHAIR, COTTON, SILK, FLAX, AND OTHER FIBROUS SUBSTANCES," to be as
follows:-
Our Invention relates, firstly, to spinning from one or more rovings, and
consists in causing such rovings to pass around an additional detached roller
or bar, so as to cause it to be partially held back. The said additional roller
may or may not be driven, and this part of our Invention is particularly appli-
cable to "mottled yarns," in which rovings of different colors are used.

page_text: Secondly, our Invention relates to doubling spun yarns, and consists in the
application for that purpose of a cap or bell placed upon the upper end of the
spindle for conveying the material to a rotatory bobbin, which rises or falls
within the said cap or bell, the arrangement being similar to one now
employed for spinning, and known in the worsted trade as the cap spindle or
"Danforth throstle."
Also our Invention relates to the wharves for such bobbins as aforesaid, and
consists in forming one of the flanges thereof larger than the other, so as to
enable the attendant to stop it readily by applying his knee..
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Benjamin Foster and Prince Smith in the Great Seal Patent
Office on the 27th April 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, BENJAMIN
FOSTER, of Denholme, near Bradford, in the County of York, Spinner, and
PRINCE SMITH, of Keighley, in the said County of York, Machinist, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of October, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Benjamin Foster and Prince Smith, Her special license that we, the said
Benjamin Foster and Prince Smith, our executors, administrators, and
assigns, or such others as we, the said Benjamin Foster and Prince Smith,
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 "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR SPINNING AND DOUBLING WOOL, ALPACA, MOHAIR, COTTON, SILK,
FLAX, AND OTHER FIBROUS SUBSTANCES," upon the condition, amongst others,
that we, the said Benjamin Foster and Prince Smith, by an instrument in
writing under our 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
Letters Patent..

page_text: : NOW KNOW YE, that we, the said Benjamin Foster and Prince Smith,
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 and accompanying Drawings (that is to say) :-
Our Invention relates to machinery or apparatus for doubling spun yarns,
and consists in the application for that purpose of a cap or bell placed upon
the upper end of a spindle for conveying the material to a rotatory bobbin, which
rises and falls within the said cap or bell, the arrangement being similar to
one now employed for spinning, and known in the worsted trade as the cap
spindle, and also known as the Dauforth throstle.
Also, our Invention relates to the wharves for such bobbins as aforesaid,
and consists in forming one of the flanges thereof larger than the other, so as
to enable the attendant to stop it by applying a knee, or the same thing may
be accomplished by enlarging the diameter of both flanges, so that they shall
extend beyond the bobbin.
In the accompany Drawing the apparatus employed, according to our
Invention, is shewn in vertical section. The fixed spindle is at a supported in
a rail 6, which spindle carries at its upper end the cap or bell c. The bobbin
is shewn at d, mounted upon a tube e, which is fixed to the wharve f, f*, to
which rotary motion is communicated after the usual manner of machines of
this class. The wharve rests upon the lifting or copping rail g, which as it
rises and falls, therefore causes the bobbin to move upward and downward
within the cap or bell c. The material to be doubled passes from ordinary
rollers of doubling machines to the cap or bell, and from thence to the bobbin,
and being twisted or doubled, is wound thereon precisely as if the ordinary
process of spinning were in operation. The upper flange f* of the wharve is
of larger diameter than the lower flange, and the attendant may therefore
readily place a knee against it in order to arrest the motion of the bobbin.
It will be evident that the object of this part of our Invention is accom-
plished, by so forming a part of the wharve that it shall project beyond the
bobbin, and it will therefore appear that the same object may be gained by
forming both flanges of the wharve of larger diameter than the flange of the
bobbin.
Having thus described and ascertained the nature of our said Invention, and
the manner in which the same is to be performed, we desire it to be under-
stood that we claim as secured to us under the above in part recited Letters
Patent,―
Firstly, the employment of the arrangement above described for doubling

page_text: Secondly, forming one or both of the flanges of the wharve of larger
diameter than the flange of the bobbin.
In witness whereof, we, the said Benjamin Foster and Prince Smith,
have hereunto set our hands.and seals; this Twenty-sixth day of April,
in the year of our Lord One thousand eight hundred and fifty-nine.
