Year: 1872

page_text: LETTERS PATENT to Henry Taylor, Manager, Henry Warburton,
Carder, Thomas Taylor, Mechanic, and William Wadsworth,
Machinist, all of Bolton, in the County of Lancaster, for the
Invention of "IMPROVEMENTS IN OR APPLICABLE TO MACHINES FOR COMBING
COTTON AND OTHER FIBROUS MATERIALS."
PROVISIONAL SPECIFICATION left by the said Henry Taylor, Henry
Warburton, Thomas Taylor, and William Wadsworth at the Office
of the Commissioners of Patents, with their Petition, on the 27th
December 1872.
We, HENRY TAYLOR, Manager, HENRY WARBURTON, Carder, THOMAS
TAYLOR, Mechanic, and WILLIAM WADSWORTH, Machinist, all of
Bolton, in the County of Lancaster, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN OR APPLICABLE TO MACHINES FOR
COMBING COTTON AND OTHER FIBROUS MATERIALS," to be as follows :—
Our Invention consists in an improved combination and arrangement
of mechanism for stopping combing machines when the sliver breaks or

page_text: becomes too thin by the failure of the slivers from one, two, or more of
the combing heads of the machine, and our improvements are applied to
the drawing bead placed at the end of each combing machine, and are
formed by a balanced lever having a slit in its end through which the
sliver passes, and its friction in passing, when the sliver is full size, is
sufficient to keep the lower end of the lever which has a hook formed
upon it from coming in contact with a projection from a rocking shaft,
but when the sliver breaks or becomes too thin the lever falls, and the
hook comes in contact with the projection from the rocking shaft, one end
of which lifts, and this draws up a sliding bar that releases a sliding rod
that traverses the driving belt on to the loose pulley, the sliding rod
being acted upon by a weight or spring. The rocking shaft has motion
from an excentric upon the cross shaft of the drawing head. Combined
with the stop motion there is a brake lever which is connected with the
sliding rod by a lever and rod, so that after traversing the driving belt
the weight or spring causes the brake surface on the brake lever to
press against the side of the fly wheel on the side of the fast driving
pulley.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Taylor, Henry Warburton, Thomas Taylor, 2
and William Wadsworth in the Great Seal Patent Office on the
23rd June 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
TAYLOR, Manager, HENRY WARBURTON, Carder, THOMAS TAYLOR,
Mechanic, and WILLIAM WADSWORTH, Machincst, all of Bolton, in the 2
County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of December, in
the year of our Lord One thousand eight hundred and seventy-two, in
the thirty-sixth year of Her reign, did, for Herself, Her heirs and a
successors, give and grant unto us, the said Henry Taylor, Henry
Warburton, Thomas Taylor, and William Wadsworth, Her special license
that we, the said Henry Taylor, Henry Warburton, Thomas Taylor, and
William Wadsworth, our executors, administrators, and assigns, or such

page_text: others as we, the said Henry Taylor, Henry Warburton, Thomas Taylor,
and William Wadsworth, our exccutors, 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
3 lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ircland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN OR APPLICABLE TO MACHINES FOR
COMBING COTTON AND OTHER FIBROUS MATERIALS," upon the condition (amongst
others) that we, the said Henry Taylor, Henry Warburton, Thomas
Taylor, and William Wadsworth, by an instrument in writing under our
hands and seals, or under the hand and seal of one of us, 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 Henry Taylor, Henry Warburton,
Thomas Taylor, and William Wadsworth, 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 the accompanying Drawings (that is to say) :—
Our Invention consists in an improved combination and arrangement
of mechanism for stopping combing machines when the sliver breaks or
becomes too thin by the failure of the slivers from one, two, or more of
the combing heads of the machine, and our improvements are applied to
the drawing head placed at the end of each combing machine, and are
formed by a balanced lever having a trumpet-shaped hole in its ends
through which the sliver passes, and its friction or drag in passing,
when the sliver is of full size, is sufficient to keep the lower end of the
lever which has a hook formed upon it from coming in contact with a
projection from a rocking shaft, but when the sliver breaks or becomes
too thin the lever falls, and the hook comes in contact with the
projection from the rocking shaft, one end of which lifts, and this draws
up a connecting bar that releases a sliding rod which traverses the
driving belt on the loose pulley, the sliding rod being acted upon by
a weight or spring. The rocking shaft has motion from an excentric
upon the cross shaft of the drawing head. Combined with the stop
motion there is a brake lever which is connected with the sliding rod by

page_text: .
a lever and rod, so that after traversing the driving belt the weight or
spring causes the brake surface on the brake lever (which may also act
as the belt lever) to press against the side of the fly wheel fixed or
formed on the side of the fast driving pulley.
Fig: 1 is an end elevation; Fig. 2 is a front elevation, and Fig. 3 an
end view, showing so much of the framing and other parts of a cotton
combing machine as will be necessary for explaining our Invention.
The other Figures of the Drawings being detached parts are herein-after
referred to.
a is the framing of the machine; b is a cross shaft, commonly used in
front of the draw box of cotton combing machines. On this shaft wo
key an excentric (c) which works in a fork & secured on the end of a
shaft e, which shaft is carried in suitable bearings in brackets from the
framing, but that bearing at the excentric end of the shaft is open
upwards, so that the shaft can lift in its bearing. The excentric c
imparts a rocking motion to the shaft e, and for this reason we name it
the rocking shaft. Upon the rocking shaft a projecting finger e¹ is
fixed, which in its up-and-down movements will catch upon a hook
formed at the lower end of a balanced lever f, when the hook end is
brought towards it. This lever (f) is shown in Figs. 1 and 2, and a
detached front view of it is shewn full size by Fig. 4, and a corresponding
side view by Fig. 5. It is formed with a trumpet-shaped tube at its
upper and a hook at its lower end. Its fulcrum (f¹) is carried on a
suitable bracket (a¹) in front of the ordinary tube (9), conducting the
sliver to the calendar or delivery rollers. f" is a screw passing through
the balanced lever f, its front end having a thin plate f³ secured to it,
which is adjusted by means of the screw to come close but not in
contact with the lower fluted front roller of the drawing head below the
level of its axis, so that should a "lap" begin to form on such roller the
material will come in contact with the thin plate (f³) and press it
downwards, and consequently through the hook end of the balanced
lever towards the finger (e¹) upon the rocking shaft (c). f'arc screw
nuts upon the screw (f³), by which the balance of the lever (ƒ) is
adjusted.

page_text: and corresponding edge view by Fig. 9. This lever (i) has its fulcrum
on a bracket (¹), which bracket is secured to the framing. The end of
the lever i forms the latch which holds a hook upon the end of the
sliding stop rod, and when the rocking shaft lifts the latch end (*) of
the lever (i) is depressed, and the hook end of the stop rod (5) is released;
then a spring j¹ having its abutment against the framing, and its
opposite end against a collar on this stop rod will slide the rod endways,
and the end of the rod being connected with the strap lever k, having its
fulcrum k¹ on a bracket secured to the framing, the driving belt will be
traversed from the fast pulley (2) to the loose pulley (4), and at the
same movement a brake surface k³, carried upon the lever k), and which
surface may be faced with leathers or other suitable material, will be
brought against the side of the fly wheel, and this will almost instantly
stop the rotation of the machine. There is a stop rod (m) for stopping
the machine by hand, and there is a lever (m³) having its fulcrum m³
on the framing, and the free end of this lever is connected with this stop
rod (m), which lever (m²) will come in contact with a collar shown upon
the stop rod j, and cause it to latch upon the lever (i) when the machine
is started again, but the arrangement allows the machine to be both
stopped and started without unlatching the stop rod j which is connected
with the strap lever k by a collar or pin, so as to push that lever only in
the direction to stop the machine. We employ the rocking shaft (e)
when a separate balanced " spoon is used for the "sliver of each
combing head, and when such "spoons are arranged in a line at the
"
33
back side of the draw box we secure a bar or plate to an arm or arms
from the rocking shaft e in a line with the spoons, so that when any
one or more of the spoons falls back, their lower ends will move forward
and prevent the plate or bar from lifting, which will consequently cause
the excentric end of the rocking shaft e to lift, as before explained.
We have now particularly described the nature of our Invention, and
the mode of carrying it into effect, and claim as our Invention,-
Firstly. The stopping of combing machines by the combination and
arrangement of mechanism, substantially as herein-before described and
illustrated by the Drawings.
Secondly. The stopping of combing machines when a "lap" begins to
form in the drawing head, substantially as herein-before described.
