IMPROVEMENTS IN APPARATUS FOR SPINNING AND 16 DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES
Year: 1876

page_text: LETTERS PATENT to James Dearden, of Burnley, in the County of Lancaster,
for the Invention of IMPROVEMENTS IN APPARATUS FOR SPINNING AND
16
DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said James Dearden at the Office
of the Commissioners of Patents on the 24th August 1876.
JAMES DEARDEN, of Burnley, in the County of Lancaster
"
IMPROVEMENTS
IN APPARATUS FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS
SUBSTANCES."
This Invention relates to certain improvements in the "collar" or "bolster" used
with throstle or doubling spindles, which improvements enable the spindle to run
steadier and at a much higher speed than hitherto obtained.
In place of making the collar (which is screwed into the bolster rail) short and a
mere ferrule for the bobbin to rest upon, as heretofore I make it the same length
as the bobbin, and of a suitable size to fit loosely in the hole through the same.
This collar I bore out so as to act as a long bearing for the spindle, or if preferred, I
bore it so that the spindle only bears top and bottom to prevent extra friction.
In place of the washer cloths hitherto employed I slip over the collar a metal
washer turned so as to fit the bottom of the bobbin, and which imparts the
necessary "drag" By this arrangement a much higher speed is attainable, while at
the same time the flyer winds on more steadily and evenly.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said James Dearden in the Great Seal Patent Office on the 24th February
1877.

page_text: This Invention relates to certain improvements in the "collar" or "bolster " used
with throstle or doubling spindles, which improvements enable the spindle to run
steadier and at a much higher speed than hitherto obtained.
In place of making the collar (which is screwed or fixed with a set screw into
the bolster rail) short and a mere ferrule for the bobbin to rest upon as heretofore, I
make it about the same length as the bobbin, and of a suitable size to fit loosely in
the hole through the same. This collar I bore out so as to act as a long bearing
for the spindle, or if preferred I bore it so that the spindle only bears at top and
bottom to prevent extra friction.
In place of the washer cloths hitherto employed I slip over the collar a metal
washer turned so as to fit the bottom of the bobbin, and which imparts the
necessary "drag." By this arrangement a much higher speed is attainable, while
at the same time the flyer winds on more steadily and ovenly.
Such being the nature and object of my said Invention, I will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect, and in order that the same may be clearly understood,
I have annexed hereunto a Sheet of Drawings illustrative thereof, and have marked
the same with figues and letters of reference corresponding with those in the
following explanation thereof:-
In the annexed Drawing Fig. 1 is a vertical section, and Fig. 2, an external
elevation showing the application of my Invention to an ordinary throstle
spindle.
a, a, is the spindle; b, b, the flyer; c, c, part of the bolster rail into which a long
collar or bolster e, e, is screwed, as shown in the Drawing, or it may be fixed with a
set screw. The long collar or bolster e, e, passes through the bobbin c, c, and reaches
to the top thereof, and the bobbin turns entirely upon this long collar, whilst the
spindle a, a, revolves within it without touching the bobbin. The lower flange of
the bobbin c, c, is made concave beneath and fits on to a metal washer f, f, which
is placed loosely upon the bolster, and by means of which the necessary "drag" is
imparted to the bobbin.
Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into
practical effect, I wish it to be understood that I claim as my Invention, the
combination of the long collar or bolster with the metal washer, substantially as
shown in the annexed Drawing and herem-before particularly described
In witness whereof, I, the said James Dearden, have hereunto set my hand
and seal, this Twenty-second day of February, in the year of our Lord
One thousand eight hundred and seventy-seven.
