Year: 1863

page_text: LETTERS PATENT to James Ellison and Abraham Rogerson, both of Bury,
in the County of Lancaster, Mechanics, for the Invention of "IMPROVE-
MENTS IN SLUBBING, INTERMEDIATE, AND ROVING FRAMES, IN THROSTLES AND
WINDING MACHINES, USED FOR THE. MANUFACTURE OF COTTON OR OTHER
FIBROUS MATERIALS."
Sealed the 1st December 1868, and dated the 23rd June 1863.
PROVISIONAL SPECIFICATION left by the said James Ellison and
Abraham Rogerson at the Office of the Commissioners of Patents, with
their Petition, on the 23rd June 1863.
We, JAMES ELLISON and ABRAHAM ROGERSON, both of Bury, in the County
of Lancaster, Mechanics, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN SLUBBING, INTERMEDIATE, AND ROVING FRAMES, IN THROSTLES
AND WINDING MACHINES, USED FOR THE MANUFACTURE OF COTTON OR OTHER FIBROUS
MATERIAL," to be as follows:-
Our improvements have for their object the prevention of unequal tension of
the thread during the change in the direction of motion of the traversing rail,
and to decrease the taper of the thread on the bobbin where flanges are
not used, and consequently put a greater length of thread on the same bobbin,
also to prevent snarling of the thread on the top of the fly at the time the
traversing rail is changing its direction of motion. To accomplish this we
attach a lever to the traversing rail, and at a convenient distance from the
fulcrum of the said lever a slot is situate, through which moves an arm carried
by a stud, the said stud being movable so as to vary the action of the arm;
the said arm acts upon two catches situate on each side of it; the said catches

page_text: also act upon another lever whose fulcrum is concentric or otherwise with the
fulcrum of the other lever. A stud is fixed on one end of the last named lever,
which stud moves in a slot situate in a third lever; the other end of the last
named lever is attached to the rod connected to the wheels or other motion
for reversing the traversing rail. Two springs are also fixed-on or attached to
the first named lever, and act upon the second named lever alternately but
in different directions. The second named lever also acts upon two ratchets
which act upon a ratchet wheel, and are kept in contact with the said wheel
by means of a spring or springs. A spur wheel larger in diameter and
containing a greater number of teeth than before in use is fixed to the said
ratchet wheel, and revolves upon the same axis. The said axis has a screw cut
upon it for the purpose of moving the arm before mentioned, which regulates
the taper of the bobbin as required. The said spur wheel actuates a rack which
moves the strap on the cone drum used for varying the velocity of the bobbins
when necessary. When the first named lever is carried to the full extent of
its traverse by the traversing rail, the movable arm attached to the said lever
lifts one of the catches and releases the second named lever, which has been
pressed by one of the springs attached to the first named lever; the pressure
of the said spring causes the said lever to move through the necessary space
to change the direction of motion of the traversing rail by acting on the
mechanism for that purpose, and also acts on one of the said ratchets and
releases it from the ratchet wheel, 'which now moves one-half tooth by the
action of the rack before named, the other ratchet being in such a position
as to prevent it moving further. The screw on the axis before named now also
moves the arm attached to the first named lever, and decreases the traverse of the
traversing rail by its action on the catches being variable. The traversing rail
now moves to the other extremity of its traverse, and a similar operation of the
changing motions takes place. The axis containing the screw projects to the
front of the machine, and contains a handle for the purpose of winding back
the mechanism described as soon as one set of bobbins are finished, and placing
it in its orignal position so as to commence another set.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Ellison and Abraham Rogerson in the Great Seal
Patent Office on the 22nd December 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
ELLISON and ABRAHAM ROGERSON, both of Bury, in the County of Lancaster,
Mechanics, send greeting.

... .:
NOW KNOW YE, that we, the said James Ellison and Abraham Roger-
son, 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 accompanying Drawings (that is to
say):
Our improvements have for their object the prevention of unequal tension
of the thread during the changing of the direction of motion of the traversing
rail; and to decrease the taper of the thread on the bobbin where flanges are
not used, and consequently put a greater length of thread on the same bobbin,
also to prevent snarling of the thread on the top of the fly at the time the
traversing rail is changing its direction of motion. To accomplish this we
attach a lever a, Figs. 1, 2, 3, to the traversing rail of the machine, and at a
convenient distance from the fulcrum of the said lever a a slot is situate,
through which moves an arm c carried by a stud d, the said stud d being
movable along the slot e by the action of a spiral groovef cut in the axle b,
into which a portion of the stud d is fitted. The said arm c acts on the two
catches 9, 91, situate on each side of it, and movable on the
are secured to a portion of the framework i of the machine.
studs h; hi, which
The catches 9, 91,

page_text: catch against the projecting part n of the lever 1, Fig. 4, and the said lever
has the axle b for its fulcrum. A stud kis fixed on the lever and passes
through a slot in the framework i, and also through another slot in the lever m;
the other end of the lever m is connected to the rod o, which acts on the
wheels or other mechanism used for reversing the traversing rail which carries
the bobbins. Two springs p, P₁, are fixed or attached to the lever a, and act
upon the lever l alternately but in different directions. To the lever h is
attached a tappet g, which acts upon the two ratchets 7, 71, which move upon
studs,s, 8, attached to the framing i, and act upon the ratchet wheel t fixed on
the axle b, and are pulled towards the ratchet wheel by the spring u: The
spur wheel is fixed on the axle b, and works in or is geared to a rack which
acts upon the strap on the cone drums used for varying the velocity of the
bobbins when necessary. To the other end of the axle b a wheel or handle w
is fixed in front of the frame to allow of the stud d and the arm c being wound
back by the action of the groove f as soon as the bobbins are full. The said
rack is moved by the action of a weight in the direction pointed out by the
arrow, Fig. 1, and thereby causes the wheel to revolve as required when
either of the ratchets r, r₁, are liberated from the wheel t.
When the machine to which our apparatus is attached is set in motion, the
said traversing rail, on which rests the revolving bobbins, causes the lever a to
oscillate, which acts upon the arm c, and if the said lever a be traversing
upwards it will act upon the arm c and cause it to lift the catch g, and as the
spring p is now pressing against the lever l, the said lever will instantly
move towards the right hand (Fig. 1), the catch 9₁ will drop off the pro-
jection n, the lever m will act on the rod o, and cause the traversing rail to
instantly change the direction of its motion; the tappet 9 will knock off the
ratchet, and the wheel t will move one-half tooth by the action of the
wheel and rack and weight before mentioned. The axle 6 having now
made part of a revolution, the spiral groove f will have caused the stud d to
move along the slot e, and increase the distance between the stud d and the
catches 9, 9₁, and also the distance between the stud d and the lever a, and as
this distance will increase with every oscillation of the lever a, the time that
will elapse between the catches 9, 9₁, being knocked off will decrease with
each oscillation, and consequently the traversing rail will decrease in the
length of its traverse also, and thereby give taper to the end of the accumu-
lated thread upon the bobbins, and the taper will be less than before in use,
and snarling prevented owing to the rapidity with which the change of motion
is effected. When the lever a moves downwards, the spring p₁ presses against
the lever 1, which moves in an opposite direction to that before mentioned, and

page_text: the catch g, will be liberated, and the tappet 9 will knock off the ratchet r and
again allow the ratchet wheel to move one-half tooth, and the action of the
other portion of the mechanism will be similar to that before described. The
spring u keeps the ratchets r, r₁, pressed against the ratchet wheel when not
prevented from doing so by the tappet q. The tappet q may be worked direct
by the stud k by making the lever 7 sufficiently long so that the said stud will
clear the wheel v, and the rod o may be connected to the said tappet, and the
lever m in this case need not be used. The rack and weight before mentioned
that moves the wheel are coupled by a chain which passes over a pulley
or pulleys in such a way that the pull of the weight shall tend to lift the rack
from its bearing and so reduce the friction, thereby causing it to move more
freely.
To the knocking-off lever a link is attached, one end of which has an
inclined plane upon it, which acts upon the lever used for lifting the cone
drum, and liberates it from a slot in which it is held by the action of the
common lifting weight and chain for lifting the said drum during the opera-
tion of stopping the frame, and snarling of the thread takes place on the top
of the fly, and the thread is ready for wrapping on a fresh set of bobbins.
We use a spring for lifting the said drum when required. The change of the
direction of motion of the traversing rail is accomplished so quickly that
unequal tension of the thread is prevented..
Having thus described the nature of our Invention, and the manner in
which the said Invention is to be performed, we wish it to be understood that
what we claim is, the mechanical arrangement and combination of parts as,
herein set forth and described, and for the purpose herein named.
In witness whereof, we, the said James Ellison and Abraham Rogerson,
have hereunto set our hands and seals, this Twenty-first day of
December, in the year of our Lord One thousand eight hundred and
sixty-three.
