"We THOMAS KNOWLES of Fir Tree Cottage, Chapeltown, Turton near Bolton in the
county of Lancaster, Cotton Spinner and ROGER TATHAM of Moss Lane Iron Works,
Moss Lane, Rochdale in the county of Lancaster Machine Maker 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:-
"
Our invention relates to the flats" employed in carding-engines used for carding
cotton and other fibrous materials and our invention consists in a mode of placing or
arranging the wires" or teeth upon each of such flats" so that such "wires" or
teeth will operate upon the cotton or other fibrous material better than they have
hitherto done.
In carrying our invention into effect we so place or arrange the "wires" or teeth
upon each of such "flats" that such "wires or teeth are で set more widely apart
at one edge of the "flat" than at the other edge of the "flat" and nearer together as
they are situate farther from that edge of the flat at which the "wires** or teeth

or teeth a
wires or
set" most widely apart.
In the accompanying drawing Figs. 1 and 2 are diagrams illustrating the manner
in which our invention may be carried into effect. Fig. 1 being a
Fig. 2 a view of a portion of the wire surface" of a "flat" the
upon which are placed or arranged according to our invention. The wires
at the edge A of the "flat"are" set more widely apart than the
teeth a' at the edge B of the "flat" and the "wires" or teeth a² between those at
the edge A of the "flat" and those at the edge B of the "flat" are "set nearer
together as they are situate farther from the edge A of the "flat" b.
In some cases we in addition to placing or arranging the "wires or teeth as above
described form the "wires" or teeth of various thicknesses the "wires" or teeth being
formed of thicker material where they are farther apart and of thinner material
where they are nearer together.
"
"
This modification of our invention is illustrated in the diagrams Figs. 3 and 4 of the
accompanying drawing Fig. 3 being a cross section and Fig 4 a view of a portion of
the wire surface" of a "flat" the "wires" or teeth upon which are formed and
placed according to this modification of our invention. The "wires" or teeth cat the
edge of the "flat" are "set" more widely apart than the "wires" or teeth c' at
the edge 1 of the "flat" d and the "wires" or teeth c² between those at the edge C
of the flat" and those at the edge D of the "flat" d are
"2
set nearer together as
they are situate farther from the edge C of the "flat" d. The
"
wires or teeth care
formed of thicker material than the "wires or teeth which are "set" nearer together.
and the wires or teeth which are "set"**
nearer together are formed of thinner'
material than the "wires or teeth which are set farther apart.

flats as above described we
cause such wires" or teeth to exercise a better straightening, cleansing and combing
effect upon the cotton or other fibrous material being operated upon by such "wires

27
"Flats" the "wires" or teeth of which are placed or arranged as above described
may be used in carding-engines in which what are known as revolving flats are
employed and in carding-engines in which stationary "flats are employed.
وو
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The heroinbefore described mode of placing or arranging the "wires" or teeth
upon each of the "flats" employed in carding-engines, according to which mode the
"wires" or teeth are substantially as and for the purposes herein before described,
"set" more widely apart at one edge of the "flat" than at the other edge of the "flat
and nearer together as they are situate farther from that edge of the "flat" at which
the wires" or teeth are set" most widely apart.

2. In a "flat" in which the "wires" or teeth are substantially as hereinbefore
described "set" more widely apart at one edge of the "flat" than at the other edge of
the "flat" and nearer together as they are situate farther from that edge of the "Hat"
at which the "wires or teeth are set most widely apart, " wires or teeth of various
thicknesses, those formed of thicker material being placed where the "wires" or teeth
are "set" farther apart and those formed of thinner material being placed where
the "wires" or teeth are "set" nearer together substantially as herein before
described in reference to and illustrated in and by Figs. 3 and 4 of the accom-
panying drawing.
