Improvements in Apparatus to be Employed in Feeding Wool and
other Fibres, to. Condensing Carding, Engines or Scribbling
Machines.
I, JABEZ LEACH of Fartown Green, Fartown, Huddersfield, Yorkshire,
Scribbling Engineer, do hereby declare the nature of this invention to be as
follows:-
In the "scotch " or like intermediate feeds for feeding wool or other fibres to
the secoud card or scribbling machine, the slivers or ribbons. of fibre are deposited
in layers upon the feed lattice sheet across the width of the card, either straight
or diagonal, or as the description of feed employed may determine, and in such
manner that at each bend or turn, they are not carried over or beyond the lateral
edges of the lattice sheet and each portion is therefore fed to the .card in the
condition in which it is deposited on the feed lattice sheet. In practice I find that
the doubling of one layer over the other short of the edges of the lattice sheet or
within the width of the card produces weak or broken places; in the fibres or
rovings at the ends of the bobbins caused by the irregularities at the ends. of the
laps or slivers deposited on the feed sheet.
The object of my present invention is to avoid the production of faulty work
from the cause named and this I accomplish by the means and in the manner
hereafter set forth :-
On the feeding end' of the machine and supported in a suitable position is a
longitudinal bar or rod adapted to be reciprocated backwards and forwards by a
crank pin fixed to a crank disc, or by a cam or tappet acting, directly on said rod
or through the medium of suitable levers. At each side of the feed lattice sheet.
are beaters or plates attached to, or forming part of levers pivotted on studs
carried by brackets bolted to any fixed part of the machine. The said beaters
or plates are engaged at their free ends by projections or studs fast on the
reciprocatory bar when such bar moves in a direction towards them and they are
returned or held in engagement with said studs when the bar moves in the opposite
direction, by means of springs.
These beaters. or plates are, however, free to be moved outwardly away from the
edges of the lattice sheet independently of the action of the reciprocatory bar,
and this is done by the carriage, or some part of the feeding, mechanism employed,
which, being caused' to travel further in each direction, than previously, in order
that a short length of each sliver or lap may be deposited over or beyond the
edges of the lattice sheet or beyond the ends of the card, is adapted to engage
with and move the beaters successively out of the way to allow of such added
length being deposited at each extremity of motion of the feed. Immediately
the beaters or plates have been released by the return of the carriage or feed
mechanism, they are oscillated or vibrated on. their pivots by the action of the
reciprocatory bar and beat or gently press or force the projecting ends of the laps
back on the lattice sheet into line with the ends of the card.
By this means as much fibre can be put into the edges or ends of the laps
or slives as is desired and the production of faulty or weak places thereby
avoided.

page_text: The parts are adjustable so that the movements thereof. can be regulated to
suit requirements and the means for giving reciprocatory motion to the bar may
be actuated through gearing from any suitable part of the machine.

Improvements in Apparatus to be Employed in Feeding Wool and
other Fibres to Condensing Carding Engines or Scribbling
Machines.
I, JABEZ LEACH, of Fartown Green, Fartown, Huddersfield, Yorkshire,
Scribbling Engineer, 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:-
In the "scotch" or like intermediate feeds for feeding wool or other fibres to
the second card or scribbling machine, the slivers or ribbons of fibre are deposited
in layers upon the feed lattice sheet across the width of the card, either straight,
or diagonal, or as the description of feed employed may determine, and in such
manner that at each bend or turn, they are not carried over or beyond the lateral
edges of the lattice sheet and each portion is therefore fed to the card in the
condition in which it is deposited on the feed lattice sheet. In practice I find
that the doubling of one layer over the other, short of the edges of the lattice
sheet, or within the width of the card, produces weak or broken places in the
fibres or rovings at the ends of the bobbins caused by the irregularities at the
ends of the laps or slivers deposited on the feed sheet.
The object of my present invention is to avoid the production of faulty work
from the cause named and this I accomplish by the means and in the manner
hereafter set forth.
"
On the feeding end of the machine and supported in a suitable position is a
longitudinal bar or rod adapted to be reciprocated backwards and forwards by a
crank pin fixed to a crank disc or by a cam or tappet acting directly on said rod
or through the medium of suitable levers. At each side of the feed lattice sheet
are beaters or plates attached to or forming part of levers pivoted on studs
carried by brackets bolted to any fixed part of the machine. The said. beaters or
plates are engaged at their free ends by projections or studs fast on the reciprocatory
bar when such bar moves in a direction towards them and they are returned or
held in engagement with said studs when the bar moves in the opposite direction,
by means of springs. These beaters or plates are, however, free to be moved
outwardly away from the edges of the lattice sheet independently of the action of
the reciprocatory bar and this is done by the carriage or some part of the feeding
mechanism employed, which being caused to travel further in each direction than
previously, in order that a short length of each sliver or lap may be deposited over
or beyond the edges of the lattice sheet or beyond the ends of the card, is adapted
to engage with and move the beaters successively out of the way to allow of
such added length being deposited at each extremity of motion of the feed.
Immediately the beaters or plates have been released by the return of the carriage
or feed mechanism, they are oscillated or vibrated on their pivots by the action of
the reciprocatory bar and beat or gently press or force the projecting ends of the
laps back on the lattice sheet into line with the ends of the card.
In order that my said invention may be fully understood reference is hereinafter

page_text: made to. the accompanying drawings forming a part of this specification in
'which
Fig. 1 is elevation of so much of the feeding end of a carding engine as is
necessary to shew the application of my invention, and Fig. 2 is plan of same.
Referring to the drawings letter a represents a longitudinal bar or rod supported
in front of the: machine by brackets 6 bolted to the side frames c, said rod being
adapted to be reciprocated in an endwise direction by a crank pin d fixed to a
disc or face plate e mounted on a stud f which is driven by bevil gearing g from
any suitable or convenient rotary part of the machine. Or the said bar may be
moved backwards and forwards across the front of the machine by a cam or
tappet acting directly on the bar or through the medium of suitable levers. At
each side of the feed lattice sheet are beaters or plates i, i, pivoted on studs j, j,
carried by adjustable brackets k, k, bolted to the framework of the machine, the
rear ends of said beaters or plates being attached by flat or other form of springs 1, 1,
to short plates m, m, pivoted on studs n, n, secured to adjustable brackets k¹, k¹.
The studs n, n, are arranged in line with the studs j, j, so that the plates m, m,
shall move responsively with the beaters i, i, and only put sufficient tension on
the springs 1, 1, to ensure the beaters keeping up to their work. The said beaters
are engaged at their free ends by fingers or projections a¹, a¹, formed on, or
rivetted, or otherwise secured to the reciprocatory bar a when such bar moves in
a direction towards them, and they are returned, or held in engagement with said
fingers when the bar moves in the opposite direction by the springs 1, l. These
beaters are, however, free to be moved outwardly away from the edges of the
lattice sheet independently of the action of the reciprocatory bar a and this is
done by means of an arm p or other projection or engaging part on the carriage pl
or corresponding feeding mechanism employed for depositing the fibre on the
lattice sheet or apron, which, being caused to travel further in each direction than
previously in order that a short length of each sliver or lap may be deposited over
or beyond the edges of the lattice sheet or beyond the ends of the cards, brings.
the said arm alternately into engagement with the beaters i, i, which are thus
forced outwardly on their pivots to the extent necessary to allow for the extra
length of the lap or sliver being laid beyond the sides or edges of the lattice
sheet, as illustrated on the right hand of Fig. 2. Immediately the beaters or
plates i, i, are released by the return of the carriage or feed mechanism, they are
forced back by springs 1, 1, into engagement with the fingers a', a', which, by means
of the reciprocatory action of the bar a, oscillate or vibrate said beaters on their
pivots, whereby the overhanging portions of the fibre or lap is beaten or gently
pressed or forced back on to the lattice sheet into line with the ends of
the card.
By this means as much fibre can be put into the ends of the laps or slivers as is
desired, and the production of faulty or weak places thereby avoided.
The fingers for oscillating the beaters and the parts carrying said beaters are
adjustable, so that the movements thereof can be regulated to suit requirements.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Firstly. In "scotch" or like intermediate feeds for feeding wool or other fibres.
to carding machinery, the method and means for beating or working the fibre-
deposited beyond the edges or sides of the feed lattice sheet back into the laps
and into line with the working ends of the cards in the manner and for the
purposes substantially as shewn and described.
Secondly. In the intermediate feeding of wool or other fibres to carding
machinery, the combination, with the deposition of short lengths of fibre beyond.
the ends of the cards or lateral edges of the feed lattice sheet, of pivoted beaters
or plates such as i, i, springs acting thereon, and means for vibrating or oscillating

page_text: said beaters and for moving them alternately out of the way as the feeding
mechanism arrives at each end of its traverse, substantially as set forth and for
purposes described.
