near Manchester, in the County of Lancaster, Machine Maker, and William
James Gradwell, of Manchester aforesaid, Mechanic, for the Invention of
"IMPROVEMENTS IN MACHINERY FOR DOUBLING AND WINDING YARN AND
THREAD."
Sealed the 5th April 1878, and dated the 17th October 1877.
PROVISIONAL SPECIFICATION left by the said Samuel Brooks and William
James Gradwell at the Office of the Commissioners of Patents on the 17th
October 1877.
SAMUEL BROOKS, of the Union Iron Works, West Gorton, near Manchester, in
the County of Lancaster, Machine Maker, and WILLIAM JAMES GRADWELL, of
Manchester aforesaid, Mechanic. "IMPROVEMENTS IN MACHINERY FOR DOUBLING
AND WINDING YARN AND THREAD."
This Invention consists in an improved combination of machinery for stopping
each bobbin separately, when one of the ends of yarn or thread breaks and when
the bobbins are full.
The machine consists of a friction drum, against which the hobbins on which the
yarn or thread is wound are pressed. Each bobbin is supported in a sliding frame
which is acted upon by a spring to give the required pressure against the drum.
The yarns or threads to be doubled and wound up, on leaving the cops or bobbins
are taken through the eyes of pendulum stops which pass through a frame supported
on levers, they then pass over a glass guide rod, and then through a traversing guide
which distributes them on the bobbin as usual.
In front of the ends of the pendulum stops is a comb or other equivalent, which is
traversed to and fro by a cam on the friction drum acting on a lever.
The spring above referred to is fixed on the axle of the setting-on lever, to which
[Price 6d.1

page_text: is fixed one half of a clutch, the other part of which is fixed to one of the levers
supporting the frame of the pendulum stops.
When the ends are all passing forward to the winding-on bobbin the two parts of
the clutch are in contact, and the comb or other equivalent passes to and fro in front
of the ends of the pendulum stops, which are held back by the yarns or threads, but
as soon as an end breaks the comb comes against the end of the pendulum stop of
the broken end and moves the stop frame sideways, thereby disconnecting the clutch;
the spring which held the bobbin against the friction drum then flies up, and the
bobbin slide is drawn back by a rod connected to a plate suspended. to the carriage
slide and to one of the levers supporting the stop frame.
The moving back of the bobbin slide brings into action a pair of spring clips which
press against the ends of the bobbin, and check its momentum. When the bobbiir
is full a pin in the rod connected to the carriage slide acts on the levers, supporting
the stop frame, and by disconnecting the clutch draws the bobbin out of contact
with the friction drum, as above described.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Samuel Brooks and William James Gradwell in the Great Seal
Patent Office on the 12th April 1878.
SAMUEL BROOKS, of the Union Iron Works, West Gorton, near Manchester, in
the County of Lancaster, Machine Maker, and WILLIAM JAMES GRADWELL, of
Manchester aforesaid, Mechanic. "IMPROVEMENTS IN MACHINERY FOR DOUBLING
AND WINDING YARN AND THREAD."
This Invention consists in an improved combination of machinery for stopping each
bobbin separately when one of the ends of yarn or thread breaks, and when the
bobbins are full.
And in order that our Invention may be fully understood and readily carried into
operation, we will proceed to describe the accompanying Sheet of Drawings, in which
Fig. 1 is an elevation, and Fig. 2 a plan of part of a machine for doubling and
winding yarn and thread, constructed according to our improvements.
In these views a is the ordinary friction drum; these drums are fixed as usual to
a horizontal shaft, extending the whole length of the machine; b are the bobbins
on which the yarn or thread is wound; these bobbins instead of being supported as
usual in swing frames are supported in the frames c, which slide in the fixed rails c¹,
and they are pressed against the drums a by the springs d, acting on the axle c²,
supported in bearings projecting from the sliding frame.
The yarns or threads to be doubled and wound on the bobbins b, are taken from
the cops or bobbins through the eyes e of the pendulum stops f, which pass through
grooves in the lower end of the frame g, which is supported by the levers h, h';
these levers are drawn toward each other by the spring h³, the stops ƒ are suspended
by wires or cords to the upper end of the frame g. The yarns or threads on leaving

page_text: the eyes e are taken through the guide wires e¹ over the glass guide bar e³, then over
the guide pulley es, and then through the ordinary traversing guide e, which distri-
butes them evenly on the bobbin b, as usual.
The levers h, h¹, are provided with sockets to receive studs projecting from the
under.side of the frame g, and they are both mounted on studs fixed to the beam i.
In front of the end of the pendulum stops f is the comb or plate with holes j, which
is traversed to and fro by the cam a¹ on the axle of the drums a, acting on the
lever k.
The spring d, above referred to, is fixed to the clutch lever l, which is mounted on
the shaft, extending the whole length of the machine; to the shaft is fixed the
stop collar to limit the range of the lever l. In the lever is a slot into which a
stud projecting from the setting-on lever m enters. The setting-on levers are
mounted on studs fixed in brackets bolted to the beam i. On the same stud as the
lever m is the lever m¹, at the lower end of which is a stud acting on the arm ³ of
the lever h. The outer end of the lever forms the second half of the clutch in the
lever. In the lever h is a socket for the drop catch h³, which takes into the teeth
of the rod n, which is hinged to the lever o, projecting from the double fork o', the
fulcrum of the lever o and double fork o', is connected to projections from the axle c²
of the slide frames c. In the axle care fixed studs for the spring clips c³,
the outer ends of which are brought, when required, against the flanges of the
bobbin b..
When the yarns or threads are all passing forward to the winding-on bobbin b,
the two parts of the clutch are in contact, and the comb or other equivalent j passes
to and fro in front of the ends of the pendulum stops f, which are held back by the
yarns or threads, but as soon as an end breaks the comb comes against the end of
the pendulum stop of the broken end and moves the stop frame g sideways, thereby
disconnecting the clutch at the end of the lever from the clutch lever l. As soon
as the clutch is disconnected the pendulum stop is released from the comb j; the
spring d, which held the bobbin b against the friction drum a, then flies up; and the
bobbin slide c is drawn back by the rod n, connected to the lever o, double fork o¹,
and axle o², suspended to the carriage slide c, and connected by the drop catch h³ to
the lever h, supporting the stop frame g.
The moving back of the bobbin slide c brings into action the spring clips c³, which
then press against the ends of the bobbin b and check its momentum. When the
bobbin is full, the pin n² in the rod n connected to the carriage slide acts on the
levers supporting the stop frame, and by disconnecting the clutch draws the bobbin
out of contact with the friction drum, as above described. The pin n² is adjustable
in the rod n, and can be set in any of the holes, according to the diameter of the
bobbin b. When the bobbin is drawn from the friction drum the drop catch h³
comes against the fixed incline to liberate the drop catch from the teeth in the
rod n, to release the spring clips c³ from the ends of the bobbin.
Having thus described the nature of our Invention, and the manner of performing
the same, we wish it to be understood that we do not intend to limit ourselves to
the details given, and that we claim,-
First. The pendulum stops f, acting in the manner and for the purposes
described.
Secondly. The comb or perforated plate ; or other equivalent for acting on the
end of the pendulum stops, as described.
Thirdly. Supporting the winding-on bobbins in sliding frames, as described.
Fourthly. The spring clips for checking the momentum of the bobbins, as
described.
Fifthly. The clutch for holding the winding-on bobbin in contact with the friction
drum, as described.
Sixthly. The combination of the drop catch h³, rod n, and pin n², projecting
therefrom for disconnecting the bobbin when full from the friction drum.

page_text: And, lastly. The general combination and arrangement of the parts, forming an
improved machine for doubling and winding, as shewn and described.
In witness whereof, we, the said Samuel Brooks and William James Gradwell,
have hereunto set our hands and seals, this Eleventh day of April, One
thousand eight hundred and seventy-eight.
