Improvements in Machines for Preparing Wool and other Fibres.
JOHN BAIRSTOW SHARP, of Prospect Mill, Bingley, in the County of
York, Spinner, and SAMUEL METCALFE, of the same place, Combing Overlooker,
do hereby declare the nature of our invention to be as follows:-
This invention relates to certain improvements in machines for preparing fibres,
for the subsequent combing and other machines and has for its object, the con-
struction of the same in such a manner that a reduction of the wear and tear of the
broad leather carrying belt, known as "preparing leathers" is accomplished, the
liability of the faller pins of the machine being bent or the fibre broken minimised
and the power required to drive the machine reduced.
We accomplish our object in the following manner :-The fluted pressure rollers
at each side of the travelling fallers are dispensed with, and in lieu thereof we
mount at the feeding end of the machine a roller having a number of sharp pins
projecting from the circumference, which, on revolving draws the fibre from the
feeding apron, delivering it comparatively loose to the fallers, which, travelling at
a quicker rate draw it through the pins of the rotating roller, thereby to some
extent opening and straightening the fibre and by the fibre being free on the pins
of the revolving roller, the faller pins are not so liable to be bent or broken as is
the case when fed by a pair of rollers under pressure.
At the delivery end of the travelling fallers, another rotating roller is mounted
having a number of rows of pins projecting from the circumference, which remove
the fibre from the travelling fallers.
Between each row of pins is a movable bar, the ends of which are supported by
stationary cam grooves, so arranged that, on the roller and movable bars rotating,
the latter at a certain portion of the revolution are caused to move some distance
from the centre, and thereby remove the fibre from the pins of the roller,
delivering it to the "preparing leathers" revolving freely over rollers not under
pressure.

COMPLETE SPECIFICATION.
Improvements in Machines for Preparing Wool and other Fibres.
We, JOHN BAIRSTOW SHARP, of Prospect Mill, Bingley, in the County of
York, Spinner, and SAMUEL METCALFE, of the same place, Combing Overlooker,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to certain improvements in machines for preparing fibres
for the subsequent combing and other machines, and has for its object, the con-
struction of the machines in such a manner that, a reduction in the wear and tear
of the broad leather carrying belt known as "preparing leathers" is accomplished,
also the liability of the faller pins of the machine being bent or the fibre broken is
minimised and the power required to drive the machine reduced; and consists in
dispensing with the fluted pressure rollers at the feeding and delivery ends of the
machine, and substituting therefor, rollers having pins projecting from the circum-
ference so arranged that, the respective rollers will feed the fibre to and remove
the film from the follora

page_text: In describing our invention in detail, reference is made to the accompanying
drawings, in which
Fig. 1 represents a sectional elevation through line a. b. of such portions of a
preparing machine as are required to illustrate our invention which is added thereto.
Fig. 2. is a plan thereof, and
Figs. 3. 4. and 5. detached details.
The fluted pressure rollers hitherto used at the feeding and delivery ends of the
machine are dispensed with, and in lieu thereof, we mount rollers having sharp pins
projecting from the circumference.
At the feeding end of the machine above the rotating rollers A. A. is mounted
in suitable journals a roller B. the circumference of which is studded with sharp
pointed pins C. and is driven by toothed wheels or other well known means
connected to any convenient part of the machine.
On putting the machine in motion, the pins on the circumference of the rotating
roller B. draw the fibre from the feeding apron or plate D. and deliver it com-
paratively loose to the fallers E. which are constructed and operated in the usual
manner: the circular rotating brush B¹ clearing the pins C. of the roller B. of any
fibre not delivered to the fallers E. and by the latter travelling at a quicker rate
than the surface speed of the circumference of the roller B. the pins of the fallers E.
draw the fibre through the pins C. of the rotating roller B. thereby to some extent
opening and straightening the fibre, and by it being free on the pins C. of said
roller, the faller pins are not so liable to be bent or broken, or the fibre damaged,
as is the case when the fibre is fed to the fallers by rollers under pressure.
At the delivery end of the machine, another rotating roller F. is mounted having
a number of rows of pins P. projecting from the circumference, which remove the
fibre from the travelling fallers E. and deliver it to the "preparing leathers” G.
and H.
Between each row of pins P. projecting from the circumference of the rotating
roller F. is a movable bar R. supported at each end in the groove of the respective
stationary cam plates H. so that, on the roller F. rotating, the bars R. move
therewith and are operated towards or away from the centre of the roller in
accordance with the formation of the cam groove; a perforated plate N. being
secured at each end of the roller F. through the slot holes S. of which, the movable
bars R. pass, and are thereby driven along with the roller F. and plates "N.
independent of the pins.
Each cam plate His mounted loose on the shaft of roller F. and secured in any
convenient manner so that, the plates H are stationary, the groove H' in each
plate being concentric with the shaft for some distance.
On the rotation of the roller F. those movable bars R. that are between the
points indicated by F and F are withdrawn by the grooves H until they are
some distance below the points of the projecting pins P. thus allowing the latter to
collect the fibre from the delivery end of the fallers E. but on the rotating movable
bars R. arriving at F³ the cam grooves H' departing from the centre of roller,
cause the movable bars R. to move away from the shaft to a distance beyond the
points of the pins, by which means, the fibre is lifted or forced from the pins and
delivered to the "preparing leather" G. revolving freely and not under spring
pressure over the roller L and carrying roller M. thereby preserving the leather
and reducing the friction of the machine by dispensing with the pressure-on the
rollers hitherto required for feeding the fibre to and removing it from the-fallers of
preparing machines.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that.what we
claim is :-
1. In a machine for preparing fibres the combination of the fillers E. with the
rollers B. and F. and preparing leathers 'G. substantially in the manner-as-shown

page_text: 2. A. machine in which are combined the fallers E. roller F. bars R. and cams H'
arranged substantially in the manner and for the purpose as hereinbefore
set forth.
