IMPROVEMENTS IN MACHINES FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES
Year: 1884

page_text: I FREDERICK TOWNS POLLARD 52 Bruce St New Wortley Leeds in the County
of York Machine Joiner do hereby declare the nature of my invention for
IMPROVEMENTS IN MACHINES FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES
to be as follows:-
The use of two or more, brushes at or near the feeding part (instead of one as in
use at present,) with a separate brush motion.
For Nobles" and similar Combing Machines where circular Combs are used.
Advantages-The feeding brush being lighter my be made to run quicker and
more wool can be fed into the machine and more work got out.
The brush as at present becomes worn out much sooner at the feeding than at
the levelling part in my invention the feeding brush can be replaced with a new
one when worn out without disturbing the levelling brush which will be compara-
tively good this will be a saving in brushes.
Plan A shows feeding and levelling parts F feeding L levelling.
Plan B shows the brush as at present covering the feeding & levelling parts.
Elevation C shows the present brush which is made to rise & fall rapidly on the
wool which is over the points of the comb teeth and presses the wool into the
combs.
Plan D shows my invention two brushes one covering the feeding and the other
the levelling part.

page_text: I FREDERICK TOWNS POLLARD, 52 Bruce Street, New Wortley, Leeds, in the
County of York, Machine Joiner, do hereby declare the nature of my invention for
IMPROVEMENTS IN MACHINES FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
My invention consists in having Two rising and falling brush motions, working
.at different rates of speed, at the place where the combs come near together, where
at present only One brush motion is employed.
The two brush motions may be also worked at the same rate of speed.
The object is to have one brush motion for the feeding or pressing the fibre into
the teeth of the combs, and to run as quickly as possible, and the other brush
motion to run as slowly as possible, but keeping the fibre down into the teeth of
the combs at a proper level, during the Combing process.
I will now proceed to describe the accompanying drawings.
Plate 1 gives the plan of the comb circle C and brushes B.
Fig 1 plate 1 shows section of one brush as in use at present at each place where
the combs come near together.
Fig 2 plate 1 shows my invention with two brushes..
Fig 3 plate 1 is another arrangement of my invention the inner circle being
taken a little to the right so as to bring the retaining motion directly under the
driving shaft as fig 3 plate 2.
Fig 4 shows my invention applied to machines where the outer circumferences
of the circles come together.
The shape of the brushes and the spaces betwen them may be varied as in
figs 5, 6-7-8 plate 1.
Where the space between the brushes is straight I introduce a thin plate into
the space to prevent any fibre from rising between the brushes see P fig 2 plate 1.
Plate 2. Fig 1 shews the feeding brush taking its motion from an excentric on
the driving shaft and the levelling or retaining brush receives motion from an
eccentric can or crank on a seperate shaft made to revolve slower by means of
a belt from a small pulley on the driving shaft actuating a larger pulley on the
seperate shaft.
Fig 2 plate 2 is a side elevation of the same sbowing a support S I employ to
the end of driving shaft and Q a spring to the feeding motion and P a plate secured
to the pillar to which is fastened the framework of the brush motions.
Fig 3 plate 2 shows front elevation of another arrangement. The feeding brush F
receiving its motion from an excentric on a separate shaft on which is a small
pulley actuated by a belt from a larger pulley on the driving shaft and the retaining
brush R receives motion from an excentric or cam on the driving shaft D.
Fig 4 is a side elevation of the same.
C. C. are the comb circles.
By these means there will be better feeding-a greater quantity of fibre may be
combed and there will be less wear and tear in the brushes and comb teeth also
a steadier working of the machine.

page_text: 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 Employing Two rising and falling brush motions working at different rates
of speed at the place where the combs come near together where at present only
one brush motion is employed substantially as and for the purpose described and
shown in the drawing.
2nd Supporting the end of the driving shaft in the arrangement of dabbing
brushes herein described substantially as shewn.
3rd Applying a spring to the feeding motion in the arrangement of dabbing
brushes herein described substantially as shewn.
