page_text: LETTERS PATENT to Josiah Aked, of Halifax, in the County of York, Worsted
Spinner and Manufacturer, for an Invention of "IMPROVEMENTS IN CAPS AND
CUPS EMPLOYED IN MACHINERY FOR SPINNING AND TWISTING OR DOUBLING
WORSTED AND OTHER FIBRES."
PROVISIONAL SPECIFICATION left by the said Josiah Aked at the Office
of the Commissioners of Patents on the 17th January 1880.
JOSIAH AKED, of Halifax, in the County of York, Worsted Spinner and
Manufacturer. "IMPROVEMENTS IN CAPS AND CUPS EMPLOYED IN MACHINERY FOR
SPINNING AND TWISTING OR DOUBLING WORSTED AND OTHER FIBRES."
This Invention relates to cap and cup spinning and twisting machinery, and the
object of my Invention is to prevent the twisting of yarn either single or double
the wrong way, that is to say, to prevent the yarn being twisted the contrary way
to that intended, and in this class of machinery wrong twisted yarn is frequently
made in consequence of the driving bands being placed on the pulleys in such
manner as to cause them to revolve the wrong way.
My improvements consist in making a slit or groove in some convenient part of
the cap or cup, and at such an angle that when the said caps and cups are revolving
the way intended the slit or groove is no inpediment to the yarn, but should the cap
or cup be caused to revolve the wrong way the slit instantaneously catches the
yarn and prevents it being twisted.

the said Josiah Aked in the Great Seal Patent Office on the 17th July 1880.
JOSIAH AKED, of Halifax, in the County of York, Worsted Spinner and
Manufacturer. "IMPROVEMENTS IN CAPS AND CUPS EMPLOYED IN MACHINERY FOR
SPINNING AND TWISTING OR DOUBLING WORSTED AND OTHER FIBRES."
This Invention relates to cap and cup spinning and twisting machinery, and the
object of my Invention is to prevent the twisting of yarn either single or double
the wrong way, that is to say, to prevent the yarn being twisted the contrary way
to that intended, and in this class of machinery wrong twisted yarn is frequently
made in consequence of the driving bands being placed on the pulleys in such
manner as to cause them to revolve the wrong way.
My improvements consist in making a slit or groove or a number of slits or
grooves in some convenient part of the cap or cup, and at such an angle that when
the tubes are revolving the way intended the slit or groove is no impediment to
the yarn, but should the tube be caused to revolve the wrong way the slit
instantaneously catches the yarn and prevents it being twisted.
In order that the Invention may be better understood reference is made to the
accompanying Sheet of Drawings, wherein Fig. 1 shews the application of my
improvements as applied to a twisting frame, and Fig. 2 shews its application to a
spinning frame; A is a cap having a rim or enlargement B, and C are the slits or
grooves formed therein. It will be seen that when the driving band D is properly
on the wharle and the tube revolving in the direction of the arrow (see Fig. 3), that
the slits are no impediment, but should the driving band D be reversed and the
tube revolve the opposite way the slits will instantaneously catch the yarn
and absolutely prevent the twisting until the driving band is altered to drive
correctly.
The rim or enlargement B also strengthens the cap, and many breakages are
thereby prevented.
Having now described the nature of my Invention, and shewn by Drawings how
the same is to be performed, I would have it understood that what I believe to be
new and therefore claim as my Invention is,-
The use and employment of the slits or grooves C for the purpose substantially
as herein shewn and described.
In witness whereof, I, the said Josiah Aked, have hereunto set my hand and
seal, this Sixteenth day of July, in the year of our Lord One thousand
eight hundred and eighty.
JOSIAH AKED. (L.S.)
