Year: 1870

page_text: LETTERS PATENT to Thomas Broughton, of Keighley, in the County
of York, Worsted Spinner, and Wilson Riley, of the same Place,
Mechanic, for the Invention of "IMPROVEMENTS IN APPARATUS EMPLOYED
IN DRAWING, ROVING, DOUBLING, SPINNING, AND TWISTING WOOL AND OTHER
FIBRES."
Sealed the 31st December 1870, and dated the 4th July 1870.
PROVISIONAL SPECIFICATION left by the said Thomas Broughton and
Wilson Riley at the Office of the Commissioners of Patents, with
their Petition, on the 4th July 1870.
We, THOMAS BROUGHTON, of Keighley, in the County of York, Worsted
Spinner, and WILSON RILEY, of the same Place, Mechanic, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN APparatus
EMPLOYED IN DRAWING, ROVING, DOUBLING, SPINNING, AND TWISTING WOOL AND
OTHER FIBRES," to be as follows:-
:-
According to our improvements we employ an endless band of leather
or other suitable material to work with the surface of each of the bottom
delivery rollers, such bands being guided to form a support for the fibre

page_text: to the nip of the top delivery rollers therewith, and they are kept at the
desired tension by spring or other pressure capable of adjustment. We
also give positive motion to both of the delivery rollers. Also in place
of the bottom delivery rollers having motion given to them by their
being formed on or applied to a common shaft having the required
motion given to it the desired motion is obtained by the use of a separate
shaft having suitable gear to give motion to pairs or sets of such rollers
and their top rollers. The warves or pulleys to the bobbin spindles in
place of being fixed to or formed on them are formed to slide on such
spindles and to give them motion by friction of conical surfaces or other
clutch connection. These warves may be released singly or in series to
stop any or all of a series of spindles as required by levers or lifters and
their rods. By this means the slipping and stretching of the bands and
the distortion of the upper ends of the spindles are prevented when
stopping is desired.
Ordinarily in the spinning process the back rollers are arranged in
pairs (a top and a bottom roller) and a positive motion is only given to
the bottom rollers, the top rollers receiving motion by friction in the
motion of the bottom rollers.
In carrying out our improvements we prefer in the spinning process
to give positive motion to each of the back rollers, and to employ two or
more of them in each set so that the yarn may pass partly round cach of
them, by which we find that the delivery to the other rollers is more
uniform.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said Thomas Broughton and Wilson Riley in the Great
Seal Patent Office on the 4th January 1871.*
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, THOMAS
BROUGHTON, of Keighley, in the County of York, Worsted Spinner, and
WILSON RILEY, of the same Place, Mechanic, send greeting.

special licence that we, the said Thomas Broughton and Wilson Riley,
our executors, administrators, and assigns, or such others as we, the
said Thomas Broughton and Wilson Riley, 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 APPARATUS EMPLOYED
IN DRAWING, ROVING, DOUBLING, SPINNING, AND TWISTING WOOL AND OTHER
FIBRES," upon the condition (amongst others) that we, the said Thomas
Broughton and Wilson Riley, our executors or administrators, by an
instrument in writing under our or their hands and seals, or under the
hand and seal of one of us or them, 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
Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that we, the said Thomas Broughton and Wilson
Riley, do hereby declare the nature of the said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement thereof, that is to say:-
Our improvements relate, first, to employing an endless band of leather
or other suitable material to work with the surface of each of the bottom
delivery rollers, such bands being guided to form a support for the fibre
to the nip of the top delivery rollers. These bands are kept at the desired
tension by spring or other pressure capable of adjustment.
The improvements relate, secondly, to giving positive motion to both
of the delivery rollers.
"
Thirdly. In place of the bottom delivery rollers having motion given
to them by their being formed on or applied to a common shaft having
the required motion given to it the desired motion is, according to this
third part of the Invention, obtained by the use of a separate shaft having
suitable gear to give motion to pairs or sets of such rollers and their top
rollers.
114
Fourthly. The improvements relate to means for giving motion to the

page_text: In carrying out this part of the Invention the warves or pulleys
to the bobbin spindles in place of being fixed to or formed on them are
formed to slide on such spindles and to give them motion by friction
of conical surfaces or other clutch connection. These warves may be
released singly or in series to stop any or all of a series of spindles as
required by levers or lifters and their rods. By this means the slipping
and stretching of the bands and the distortion of the upper ends of the
spindles are prevented when stopping is desired.
Ordinarily in the spinning process the back rollers are arranged in pairs
(a top and a bottom roller) and a positive motion is only given to the
bottom of these rollers, the top roller receiving motion by friction in the
motion of the bottom rollers.
In carrying out our improvements we prefer in the spinning process
to give positive motion to each of the back rollers and to employ two or
more of them in each set, so that the yarn may pass partly round each
of them, by which we find that the delivery to the other rollers is more
uniform.
But that the Invention may be more fully understood we will by the
aid of the accompanying Drawings proceed to describe means pursued by
us in carrying the same into effect.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a sectional side view and Figure 2 a front view of parts
of apparatus arranged according to the first head of the Invention. In
each of the Figures of the Drawings the same letters are used to indicate
the same parts wherever they occur.
a are the bottom delivery rollers; 6 are top ones; and c are endless
bands of leather or other suitable material, one of which works by
passing over the surface of each of the bottom rollers a whilst each also
passes over and is kept distended by a roller d, and in order to effect the
desired tension on each band c each roller d is supported upon the ends
of arms e from an axis e¹ which is supported with capability of rocking
in the fixed standards f, and which axis is also formed with another
arm e² which is acted upon by the rod e³ and spring e* with capability
for varying the power exerted by the spring on the band c as required.
If desired weight instead of spring pressure may be employed. By this
employment of endless belts support is given to the fibre in its passage
to the delivery rollers.

page_text: These Figures 1 and 2 also show a means of giving a positive motion
to both the top and bottom delivery rollers. As shewn, this is effected
by means of the teeth of a toothed pinion 6' affixed to the axis b³
of cach pair of the top delivery rollers taking into the teeth of a
corresponding pinion a¹ affixed on the axis a³ of each pair of bottom
rollers a.
We will now describe the third part of our Invention, which is shown
applied by a perspective view of parts at Figure 3, and where it will bo
seen that whilst each pair of top delivery rollers has applied to it a
pinion by which to gear with the teeth of a corresponding pinion a¹ on
a pair of bottom delivery rollers motion is given to the pinions a¹ by
means of other pinions fon a separate axis f¹, and this axis f¹ extends
all across the machine or to an extent adapted by being provided with
a scries of such pinions f, one for each pair or set of rollers a and
their top rollers 6 to give motion to series of pairs or sets of delivery
rollers.
By these means increased facility is afforded for effecting changes in
both the bottom and the top delivery rollers.
We will now describe the fourth part of the Invention, which is shown
applied by side view and front view of parts at ₁igures 4 and 5, and
by separate sectional view of a portion thereof at Figure 6. In these
Figures it will be seen that the warve g in place of being affixed to the
bobbin spindle so that any motion given to that warve must of necessity
give motion to the spindle h, it is applied to run loosely on that spindle
so that when motion is given to that warve by a band in motion acting
in the groove thereof, it only gives motion to the spindle h, when its
inclined or conical internal surface rests upon or is in contact with the
corresponding conical surface i affixed to the spindle 7.
We would, however, remark, that although we have shown conical
surfaces to effect contact, other form of frictional or clutch connection
may be adopted; j is a lever which is supported to turn on an axis of
motion from the bar 1, so that when its lower end 11 is pressed inwards
the upper and crooked end may at once act on the under side of the
warve to raise it from frictional contact with the conical surface i,
and also by bearing against the spindle / cause it to cease rotation
during a change of bobbin or for other purpose.
Figures 7 and 8 show an external view and a sectional view of a slight
modification of the above.

page_text: In Figure 3, l, m, and r are the back rollers, each of which has
positive motion given to it by having affixed on it a pinion A, m³, and n¹
respectively, the teeth of which are geared together. The fibre under
operation is represented by the lines o, o, and it will be seen that in each
case the fibre passes over the top roller n down between that roller n
and the roller m partly around which it passes, and thence between that
roller m and the roller 1, and then down under the roller to the delivery
rollers a, b, by which a more uniform delivery is effected.
Having thus described our improvements in apparatus employed in
drawing, roving, doubling, spinning, and twisting wool and other fibres,
together with means which we adopt in carrying the same into effect,
we would have it understood that we do not confine ourselves to the
precise arrangements of parts shown and described, as these may be
varied; but what we claim is,―
First. The use of an endless band of leather or other suitable material ]
to work with the surface of each of the bottom delivery rollers, acting
in manner substantially as described.
Secondly. We claim for giving a positive motion to both top and
bottom of the delivery rollers.
Thirdly. We claim for giving motion to series of delivery rollers by 2
means of a separate shaft with suitable gear, substantially as described.
Fourthly. We claim for giving motion to the bobbin spindles from the
warves by frictional contact of conical surfaces or other suitable clutch
connection.
In witness whereof, we, the said Thomas Broughton & Wilson
Riley, have hereunto set our hand and seal, this Thirty-first
day of December, in the year of our Lord One thousand eight
hundred and seventy.
