IMPROVEMENTS IN DRIVING THE SPINDLES OF DOUBLING AND SPINNING FRAMES
Year: 1863

page_text: LETTERS PATENT to Joseph Thomas Webster, of Mansfield, in the County
of Nottingham, for the Invention of "IMPROVEMENTS IN DRIVING THE
SPINDLES OF DOUBLING AND SPINNING FRAMES."
Sealed the 19th April 1864, and dated the 23rd October 1863.
PROVISIONAL SPECIFICATION left by the said Joseph Thomas Webster
at the Office of the Commissioners of Patents, with his Petition, on
the 23rd October 1863.
I, JOSEPH THOMAS WEBSTER, of Mansfield, in the County of Nottingham,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
DRIVING THE SPINDLES OF DOUBLING AND SPINNING FRAMES," to be as follows:-
The object of this Invention is to drive the spindles and bobbins of such
machines both by a positive motion, the spindles being driven so much faster
than the bobbins as shall cause them to put the requisite amount of twist into
the thread.
At or near the foot of the spindle is made fast a small wheel with a grooved
edge, and above this I place another similar grooved wheel mounted so as to
run loosely on the spindle. In the upper face of this last-mentioned wheel is
fixed an upright pin or peg which connects the wheel with the bobbin, and
thus drives the latter. These wheels are both driven by a face wheel keyed on
a horizontal shaft, which wheel has two wedge-formed rings or projections on
its face, which fit respectively into the grooves on the edges of the two wheels

page_text: on the spindle, the outer or larger rim acting on the upper or loose wheel, and
thus driving the bobbin, so as to wind on the thread, whilst the inner or smaller
rim acts on the lower or fast wheel, and thus drives the spindle, and puts in
the twist; the difference between the diameters of the two rims on the face
wheel imparting proportionately different speeds to the spindle and bobbin and
thus regulating the amount of twist put into the thread. This method of
driving the spindle and bobbin causes much less vibration and noise than the
methods hitherto employed and considerably diminishes the wear and tear of
the machine. The driving wheels are kept in contact by means of a spring,
which acts on the spindle, and is provided with a small projection or handle,
by means of which the operative can at any time throw the spindle and
bobbin out of and into gear with the face wheel with the greatest facility, so
that the most complete control over the spindle is obtained.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Thomas Webster in the Great Seal Patent Office. on
the 21st April 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
THOMAS WEBSTER, of Mansfield, in the County of Nottingham, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of October, in the year of our
Lord One thousand eight hundred and sixty-three, in the twenty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Joseph Thomas Webster, Her special licence that I, the
said Joseph Thomas Webster, my executors, administrators, and assigns, or
such others as I, the said Joseph Thomas Webster, my executors, adminis-
trators, 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 Inven-
tion for "IMPROVEMENTS IN DRIVING THE SPINDLES OF DOUBLING AND SPINNING
FRAMES," upon the condition (amongst others) that I, the said Joseph Thomas
Webster, my executors or administrators, by an instrument in writing under
y, or their, or one of their 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 Scal

page_text: Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Thomas Webster, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement in writing, and on reference to the accompanying Drawings,
that is to say-
The object of this Invention is to drive the spindles and bobbins and
cops of such machines both by a positive motion, the bobbin or cop to
be driven so much faster than the spindle as to give the requisite stretch
and wind the thread on to the bobbin or cop as it receives the required.
amount of twist.
Near the foot of the spindle A is made fast a wheel B, one inch more
or less in diameter, grooved on the edge, and above this I place another
grooved wheel, same diameter, C, mounted so as to run loosely on the
spindle on this last-mentioned wheel is fixed a pin D, of sufficient length
as to allow of another pin E attached to the plate F by means of a socket
carried through the lifting bar, which socket also forms the upper bearing
of the spindle to traverse the bobbin or cop on the plate F; the bobbin
or cop rests and is carried round, thus saving the loss of power caused by
the drag of the bobbin on the lifting rail as at present in use. These
wheels are both driven by a face wheel G, keyed on a horizontal shaft H,
which wheel has two wedge-formed rims or projections on its face which
fit respectively into the grooves of the two wheels B and C, the outer or
larger rim acting on the upper or loose wheel, and thus drives the bobbin
so as to wind on the thread, whilst the inner or lesser rim acts on the
lower or fast wheel, and puts in the twist, the difference between the two
rims on the face wheel imparting proportionately different speeds to spindle
and bobbin, and thus regulating the stretch on the thread and giving an even
and regularly twisted yarn.
Perfect control over the spindle is obtained by placing at its foot a small
spring I, provided with a handle, by means of which the operative can at any
time throw the spindle and bobbin out and into gear with the driving wheel
with the greatest facility and ease.
5 For traversing the lifting rail of doubling frames the ordinary or "mangle
motion" is the best adapted.
For traversing the thread of the throstle spinning frames I provide a
method as herein-after described in Figure 2 of the accompanying plate.
For the throstle spinning frame a different motion is required to form a cop;

page_text: for this purpose I provide two cones placed conversely one to drive the other, the
driving a cone fixed on a shaft B has six, more or less, rims or wheels fastened
on the cone, the first rim or wheel to be about six inches in diameter, to have
seven cogs placed upon it one-eighth of an inch apart, the next wheel to be
about a quarter of an inch less in diameter, and upon this wheel are placed
seven cogs, same as the first, and each succeeding wheel to have the same
number placed, so that as each wheel ceases to drive the next commences;
this describes one half of the driving cone. At the end of the cogs on the
smaller wheel are placed seven more cogs' immediately following. On the
next wheel are placed seven cogs, placed so as to act immediately the wheel
before it ceases to drive, and so on with each succeeding wheel, till the first-
mentioned seven cogs are in gear again, thus having effected one revolution of
the driving cone the cone B also fixed on a shaft, and to have the same number
of rims or wheels, and the same number of cogs only; this cone must be
placed, and the cogs thereon, conversely to the cone A; on the end of
the shaft upon which this cone is placed is fixed an excentric or heart to
a lever which is attached to the lifting bar; on the end of the
lever is fixed a builder screw to regulate the length of the cop.
And I may here observe that I do not confine myself to any sized cones nor
any number of wheels, nor yet any number of cogs. I claim protection for
gaining an increasing and diminishing speed of traversing the thread by means
of converse cones.
In witness whereof, I, the said Joseph Thomas Webster, have hereunto
set my hand and seal, this Twenty-first day of April, in the year of our
Lord One thousand eight hundred and sixty-four.
