Year: 1879

page_text: LETTERS PATENT to George Little, of Oldham, in the County of Lancaster,
Mechanical Engineer, and Thomas Charles Eastwood, of Bradford, in the
County of York, Machine Wool Comber, for the Invention of "IMPROVEMENTS
IN MACHINERY FOR COMBING FIBRES."
Sealed the 6th April 1880, and dated the 7th November 1879.
PROVISIONAL SPECIFICATION left by the said George Little and Thomas
Charles Eastwood at the Office of the Commissioners of Patents on the 7th
November 1879.
GEORGE LITTLE, of Oldham, in the County of Lancaster, Mechanical Engineer,
and THOMAS CHARLES EASTWOOD, of Bradford, in the County of York, Machine
Wool Comber. "IMPROVEMENTS IN MACHINERY FOR COMBING FIBRES,"
This Invention relates to further improvements in machinery for purpose
aforesaid of the class for which Letters Patent were granted to us, the said George
Little and Thomas Charles Eastwood, of Bradford, in the County of York, Machine
Wool Comber, No. 839, A.D. 1873.
The present Invention comprises-
Firstly. Improved appliances for carrying and imparting to the gills the requisite
"to" and "fro" or reciprocating motion.
Secondly. Improved appliances for carrying and operating the divider.
Thirdly. A friction clutch which when thrown out of gear ensures automatic
relative adjustment of certain going parts of the machine before the latter resumes
motion.
According to this my said Invention in order to secure the requisite reciprocating
motion of the gills the latter are mounted in or upon a frame carried by rocking
arms, having for fulcrum a cross rail near the foot of the machine; the friction and
wear and tear of sliding the gills as heretofore is obviated. The motion is imparted

and combined with the foot rail of the rocking arms, so that its lateral traverse

disc, pinion wheel, and spring duplicate disc, a catch, and catch boss; the contact

projections; there are two corresponding notches in the catch boss, so that when
obstruction to the free working of the machine from any cause arises the discs
separate, and frictional contact between the two is resumed only when the recesses
and holding bits are again in gear, these being so spaced as to ensure contact and
renewed motion of the fallers when the nipping part of the revolving nip jaws
arrives at its position to take hold of the tuft of fibre under operation.

GEORGE LITTLE, of Oldham, in the County of Lancaster, Mechanical Engineer,
and THOMAS CHARLES EASTWOOD, of Bradford, in the County of York, Machine
Wool Comber. "IMPROVEMENTS IN MACHINERY FOR COMBING FIBRES."
This Invention relates to further improvements in machinery for purpose
aforesaid of the class for which Letters Patent were granted to us, the said George
Little and Thomas Charles Eastwood, Number 839, A.D. 1873.
The present Invention comprises-
Firstly. Improved appliances for carrying and imparting to the gills the requisite
to and fro or reciprocating motion.
Secondly. Improved appliances for carrying and operating the divider.
Thirdly. A friction clutch which when thrown out of gear ensures automatic
relative adjustment of certain going parts of the machine before the latter resumes
motion.
According to this our said Invention in order to secure the requisite reciprocating
motion of the gills the latter are mounted in or upon a frame carried by rocking
arms, having for fulcrum a cross rail near the foot of the machine; the friction and
wear and tear of sliding the gills as heretofore is obviated. The motion is imparted
to the rocking arms by means of eccentric or cams.
The "divider" is connected and combined with the foot rail of the rocking arma,
so that the "divider's" lateral traverse during its whole course is equa distant from
or parallel to the curvature of the gills, and the divider's action upon the fibre is
equal throughout.
The friction clutch comprises disc, pinion wheel, and spring duplicate disc, a catch,
and catch boss; the contact faces of the friction discs are provided with two
recesses and two holding bits or projections; there are two corresponding notches
in the catch boss, so that when obstruction to the free working of machine from
any cause arises the discs separate, and frictional contact between the two is
resumed only when the recesses and holding bits are again in gear, these being so
spaced as to ensure contact and renewed motion of the fallers when the nipping
part of the revolving nip jaws arrives at its position to take hold of the tuft of
fibre under operation.
Such being the nature and object of this our said Invention, we will now proceed
to describe same in detail, and have annexed two Sheets of Drawings illustrating
the Invention.
DESCRIPTION OF THE DRAWINGS.
In order to secure the requisite reciprocating motion of the gills 1 the latter are
mounted in or upon a frame 2 carried by rocking arms 3, having for fulcrum a
cross rail 4 near the foot of the machine; the friction and wear and tear of sliding
the gills as heretofore is obviated. The motion is imparted to the rocking arms 3
by means of eccentric or cams 5.
The "divider" 6 is connected and combined by bracket 7, and arms 8, 9, with

page_text: a catch 9, and catch boss 10; the contact faces 11, 11, of the friction discs are
provided with two recesses 12, 12, and two holding bits 13, 13, or projections.
There are two corresponding notches in the catch boss, so that when obstruction to
the free working of machine from any cause arises the discs separate, and frictional
contact between the two is resumed only when the recesses and holding bits are
again in gear, these being so spaced as to ensure contact and renewed motion of the
faller when the nipping part of the revolving nip jaws arrives at its position to
take hold of the tuft of fibre under operation.
Having thus fully described the nature and particulars of this our said Invention,
together with the manner in which same is to be or may be performed or carried
into practical effect, we would have it understood that we claim,-
Firstly. The combination of gills 1, frame 2, arms 3, operated by cam or eccentric,
in manner and for purpose as described and illustrated.
Secondly. The "divider" 6 in combination with the rocking gills, and when such
"divider" is mounted and operated in manner described and illustrated.
Thirdly. The use of the peculiar friction clutch constructed as described and
illustrated, and when in combination with the rocking gills described and illustrated.
In witness whereof, I, the said George Little, for and on behalf of myself and
the said Thomas Charles Eastwood, have hereunto set my hand and seal,
this First day of May, in the year of our Lord One thousand eight hundred
and Antv.
