IMPROVEMENTS IN COMBING MACHINES
Year: 1884

page_text: I JOHN CHARLES WALKER of Shipley Fields Mill, Shipley near Bradford in
the County of York, Mechanical Engineer do hereby declare the nature of said
invention for "IMPROVEMENTS IN COMBING MACHINES to be as follows:
"
The object of my improvements is to improve the action of the rollers employed
on what are known as "Nobels" combing machines.
Instead of making the feed or creech rollers of wood as hitherto I form them
of metal tubes, such tubes having fluted or corrugated surfaces and therefore
rendered much stronger than plain tubes or wooden rollers and not so likely to
become bulged or otherwise injured. The ends of these corrugated tubes are closed
by metal plates one of which forms a flange to the roller such flange being for the
purpose hereafter described.
These end plates are provided with holes at the
centre tapped for the purpose of receiving the adjustable studs or pins which are
screwed therein. These studs or pins being adjustable can be arranged to suit
the varying distances between the bearings.
In order to impart the intermittent rotary movement to the feed rollers I mount
and hinge an arm on a suitable bracket, this arm remains stationary until the
aforesaid flange on each roller successively comes in contact therewith and by the
pressure of the feed rollér as it traverses along, the arm is forced up an incline and
owing to the frictional contact between the feed roller and the arm causes the feed
roller to rotate.
The requisite pressure to ensure the required amount of friction between the
arm and the flange is imparted to the arm by springs or weights in connection
therewith.
I also improve the action of the drawing off rollers by arranging the gearing
in such manner as to be enabled to employ much smaller drawing-off rollers than
hitherto with much less injury to the drawing off leathers.
Hitherto a considerable amount of difficulty has been experienced especially
where smaller rollers are required, in gearing the two rollers together with spur
pinions so that the pinions would not be in such a position as to be dangerous to
the attendant as well as a great liability of the material operated upon becoming
entangled with such gearing.
Now in my improvements I provide spur wheels (the size of which depends
upon that of the rollers) on the roller shaft these are geared together and concealed
within the bushes or bearings in which the roller shafts are mounted.
Doted this Second day of January 1884.

I JOHN CHARLES WALKER of Shipley Fields Mill Shipley near Bradford in
the County of York Mechanical Engineer do hereby declare the nature of my
Invention for IMPROVEMENTS IN COMBING MACHINES and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying drawings and to the
letters and marks thereon.
The object of my Improvements is to improve the construction of the rollers
employed on what are known as Nobel's Combing Machines.
Instead of making the feed or creel rollers of wood as hitherto I form them of
metal tubes, such tubes having fluted or corrugated surfaces, and are therefore
rendered much stronger than plain tubes or wooden rollers and not so likely to
become bulged or otherwise injured.
The ends of these corrugated tubes are closed by metal plates, one of which
forms a flange to the roller, such flange being for the purpose hereafter described.
These end plates are provided with holes at the centre tapped for the purpose
of receiving the adjustable studs or pins screwed therein. These studs or pins
being adjustable can be arranged to suit the varying distances between the
bearings.
In order to impart the intermittent rotary movement to the feed rollers I mount
and hinge an arm on a suitable bracket, this arm remains stationary until the
aforesaid flange on each roller successively comes in contact therewith, and by the
pressure of the feed roller as it traverses along, the arm is forced up an incline
and owing to the frictional contact between the feed roller and the arm causes the
feed roller to rotate.
The requisite pressure to ensure the required amount of friction between the
arm and the flange is imparted to the arm by springs or weights in connection.
therewith.
I also improve the action of the drawing off rollers by arranging the gearing in
such a manner as to be enabled to employ much smaller drawing-off rollers than
hitherto with much less injury to the drawing-off leathers.
Hitherto a considerable amount of difficulty has been experienced especially
where smaller rollers are required in gearing the two rollers together with spur
pinions, so that the pinions would not be in such a position as to be dangerous to
the attendant, as well as as great liability of the material operated upon becoming
entangled with such gearing.
Now in my improvements I provide spur wheels (the size of which depends upon
that of the rollers) on the roller shafts, those are geared together and concealed
within the bushes or bearings in which the roller shafts are mounted.
And in order that my invention may be more readily understood reference is
given to the accompanying drawings and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a front elevation, and Fig. 2 a plan looking on the top shewing a pair
of drawing-off rollers constructed in accordance with my improvements. Fig. 3
is a side elevation and Fig. 4 a plan of two pairs of feed or creel rollers employed
in combing (circular) machines having my improvements applied thereto.
Instead of making the feed or creel rollers of wood as hitherto I form them of
metal tubes a Figs. 3, 4, and 5, such tubes having fluted or corrugated surfaces as
shewn in cross section in Fig. 5 and are therefore rendered much stronger than
plain tubes or wooden rollers and not so likely to become bulged or otherwise
injured. The ends of these metal tubes a are closed by metal plates b and c
one of which c forms a flange to the roller such flange being for the purpose
hereafter described.

page_text: These end plates are provided with bosses d having holes through them for the
purpose of receiving the adjustable pins or studs e, which are screwed therein
and held in position by the locking nuts i. These studs or pins being adjustable
in the manner shewn can be arranged to suit the varying distances between the
bearings.
In order to impart the intermittent rotary movement to the feed rollers a
I mount or hinge an arm f on a bracket attached to the standards k of the
machine. Beneath this arm ƒ is fixed an incline g cast on or otherwise attached
to the bracket h which is fixed to one of the standards of the machine. The
arm f is so hinged that it can move in a vertical direction and also rotate about
the pin but remains stationary until the aforesaid flange con each roller
successively comes in contact with the end of the arm at fi forcing the arm up
the incline and by the frictional contact and motion of the end of the arm fi
against the flange c rotates the roller a for feeding the material.
The requisite pressure to ensure the necessary amount of friction between the
end of the arm and the flange c is imparted to the arm f by means of springs m
or weights connected therewith. The amount of rotation may be adjusted by
moving the pin in the slot j bring the end f₁ of the lever f nearer or further away
from the centre of the disc c.
I also improve the action of the drawing-off rollers by arranging the gearing
in the manner shewn in Figs. 1 and 2 whereby I am enabled to employ much
smaller drawing off rollers n and o than hitherto and with much less injury to the
leathers.
Hitherto a considerable amount of difficulty has been experienced (especially
where smaller rollers are required) in gearing the two rollers together with spur
pinions so that the pinions would not be in such a position as to be dangerous to
the attendant as well as to offer a great liability thereby of the material operated
upon becoming entangled with the gearing.
Now in my improvements I provide on the roller shafts 2 and the spur
wheels and s the size of which depends on that of the rollers n and o (being
small when the rollers n and o are small). These are geared together and concealed
within the bushes or bearings vand x in which the roller shafts p and q are
mounted.
The herein before described arrangements form parts of one combing machine,
other portions of which not described may be of ordinary construction.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
1°. The construction of the feed or creel rollers of combing machines of metal
tubes having fluted or corrugated surfaces substantially as herein set forth.
2°. The application of adjustable studs or pins e to the feed or creel rollers
substantially as herein set forth.
3°. The arrangement and application of the mechanism for automatically
rotating the feed or creel rollers of combing machines substantially as
herein set forth.
4°. The arrangement of spur wheels 7 and 8 concealed within the bushes or
bearings and x for gearing together the drawing-off rollers n and o of
combing machines substantially as herein set forth.
