Improvements in and relating to Carding Engines.
We, ERNEST HANNAN GILLETT, of Crosse Hall Works, Chorley, in the County
of Lancaster, Cotton Spinner, and JAMES FOGG, of 8, Crosse Hall Street,
Chorley, aforesaid, Foreman, do hereby declare the nature of this invention
to be as follows:-
Our invention relates to improvements in travelling or revolving flat carding
engines.
The object of our invention is to construct the flats & flexible bends of card-
ing engines in such a manner that all the teeth or wires of the flats are in
turn brought into contact with the cotton so that one portion of the teeth or
wire, of the flats, is used to deal with the entangled," &, dead, cotton, seed,
leaf, &c. whilst the other portion of the teeth or wire being reserved is in better
condition for combing the fibres, after they have to a great extent, been sepa-
rated from the heavier impurities.
In carrying out our invention, we construct the flat ends, so as to have two
working or sliding surfaces, & so arrange the flexibles, that as the flat first comes
into contact with them, the toe of the wire, will come in contact with the cotton
on the cylinder, & as the flats travel or slide around the flexibles, their position
is gradually altered, so as to bring all the teeth or wires on the flats in their
turn in contact with the cotton on the cylinder.
Also where the flat comes in contact with the cotton with the toe of the flat
nearest to the cylinder. The flexibles can be adjusted, so as to keep the
flat with its toe nearest the cylinder, during the greater part of its travel
around the first half or thereabouts of the flexibles, without destroying the
concentricity of the flats, which may have passed the first half or thereabouts
of the flexibles. When the flat has reached half way round the flexibles or
thereabouts, the teeth or wires at the heel of the flat comes in contact with
the cotton, & remains so during its passage round the remaining part of the
flexibles.
The flexible may be arranged, in one, two, or more parts, & may be secured
together by hinges, bolts, or other suitable, arrangement. The parts can also
be made adjustable to each other.

page_text: Chorley, and now of 172, Lyons Lane, Chorley, aforesaid, Foreman, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention relates to improvements in travelling or revolving flat card-
ing engines. The object of the invention is to construct the flats and flexible
bends of carding engines in such a manner that all the teeth or wires of the
flats are in turn brought into contact with the cotton or fibre whereby one por-
tion of the teeth or wire of the flats may be used to deal with the entangled
and dead cotton seed leaf and the like, whilst the other portion of the teeth or
wire being reserved will be in better condition for combing the fibres after
they have to a great extent been separated from the heavier impurities.
In carrying out our invention we construct the flat ends so as to have two
working or sliding surfaces and so arrange the flexible bends that as the ilat
first comes into contact with them the toe of the wires will come in contact
with the cotton on the cylinder and as the flats travel or slide around the flexible
bends their position is gradually altered so as to bring all the teeth or wires
on the flats in their turn in contact with the cotton on the cylinder the flat
finally finishing up by working with the heel of the wires.
Where the flat comes in contact with the fibre, with the toe of the flat nearest
to the cylinder, the flexible bends are arranged so as to keep the flat with its
toe nearest the cylinder during the greater part of its travel around the first
half or thereabouts of the flexible bends without destroying the concentricity
of the flats which may have passed the first half or thereabouts of the flexible
bonds. When the flat has reached half way round the flexible bends or there-
abouts the teeth br wire at the heel of the flat comes in contact with the
fibre as stated and remains so during its passage round the remaining part of
the bends. The bends for this purpose may be arranged in one, two, or more
parts, and may be secured together by hinges, bolts, or other suitable arrange-
ment. The parts can also be made adjustable to each other.
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying draw-
ings, in which :-
Fig. 1 is a diagram representing our improved arrangement of flexible bend
in side elevation.
Fig. 2 is a plan view of Fig. 1.
Fig. 3 is an elevation of the flexible bend shewing three flats in different
positions thereon.
!
Fig. 4 is a side elevation of one end of a flat formed according to our inven-
tion, looking in the direction of the arrow y Fig. 6.
Fig. 5 is an underside view of Fig. 4.
Fig. 6 is an end view of same, and
Fig. 7 is an end elevation of the flat, looking in the direction of the arrow z,
Fig. 6.
According to this invention the flats A are each formed at their ends with
three working or sliding surfaces e f 9, the surfaces e and f being on one
edge and being of different heights, while the surface 9 occupies the other edge
and is approximately of the same height as surface f. The other end of the
flat it will be understood is formed with the same surfaces and the flexible
bends B on both sides are formed with three surfaces a-b-c of which about
one half or the leaving end c is concentric with the teeth on the cylinder D
while about one half or the entering portion of the bend is formed in two
circular wedge shaped surfaces which are struck from the centres a¹-3¹ respec-
tively, the surface a being struck from the centre so that if such surface c
were continued as indicated by the broken line d the surface a would be out-
side or above d and the surface 6 would be inside or under d. All three surfaces
meet at the point L or thereabouts.

page_text: The arrangement is such that when the fat is resting with its surfaces •
and 7 on the rait of bend a the toe part of the wire is brought lower than the
heel, while when the flet rests with the suas f end g on the part of bend a
its heel is lower than its toe as usual, an intermediale position bringing the
flat level.
The action is as follows:-The flats revolving on their endless chains first
come in contact with the flexible bend at the entering end I (Figs. 1 and 3) the
surfaces e and g of the flat coming in contact with part a of the bend so that
as shewn at H (Fig. 3) the toe of the wires are nearest to the teeth on the
cylinder D. The Hat remains in this position until the surface f begins to
come in contact with part of the bend which lifts the surface è of the flat
away from part a of the bend and as both parts a and b of the bend are wedge
shaped the part a will bring the heel nearest the cylinder while at the same
time part is taking the toe of the fat further away from the cylinder so that
the flat is partly rolled over, assuming the position J (Fig. 3) when the centre
of the wires are in contact with the teeth of the cylinder while the continued
onward movement past point L (Fig. 1) further rolls the flat so that when the
surfaces and 9 are on the part e the flat assumes the position shown at K with
the heel nearest to the cylinder teeth so that the wires at the heel which have
not hitherto had to do the work of freeing the fibres from seed, leaf, and the
like, and are in a comparatively clean condition are ready to do the usual work
of carding around the remaining portion of the cylinder.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1
(1) In a revolving flat carding engine, means for causing the flats to com-
mence the carding from one edge of same, and means for partly rolling same
over during their travel and causing same to finish the carding from their
other edge, as herein described and substantially as illustrated by the annexed
drawings.
(2) In combination with the cylinder of a revolving flat carding engine, a
flat having an upper and a lower surface on one edge of same, and a flexible
bend having wedge shaped surfaces of different height, such surfaces merging
into a surface concentric with the cylinder, as and for the purpose herein described
and substantially as illustrated by the annexed drawings.
(3) In combination with the cylinder of a revolving flat carding engine, a
flat having an upper and a lower surface and a bend of circular wedge shape
having surfaces of different heights adapted to carry the flats and according to
the position of same thereon to present the toe or heel of the wires to the
cylinder, as and for the purpose herein described and substantially as illustrated
by the annexed drawings.
