Improvements in the "Flats" of Carding Engines for Carding
Cotton, Wool, and other Fibrous Substances.
I JOHN ALLEN DYSON of Butler Street Mills Manchester in the County of
Lancaster Manager do hereby declare the nature of this invention to be as follows:-
This invention relates to the construction of the "flats" or flat cards used in
Carding Engines, and to the method of attaching or securing the wire card clothing
thereto; the object of the invention being to utilize the full width of the "flat" so as
to obtain an increased carding surface upon an endless chain of a given length.
Hitherto the card clothing for flats has been made the full width of the "flat" but
with a blank margin at each edge for fastening or attaching the clothing to the face of
the "flat" by rivets or by wires or otherwise; and the consequence has been that a
large amount of carding surface has been lost equal to double the width of this margin
between each two "flats."
22
According to my invention I make the card clothing for "flats wider than the
face of the "flat" itself, the card covered surface being of the width of the "flat" with
a margin outside upon each edge.
I make the edge of the "flat" with a recess and I turn over the margin of the card
clothing at each edge, and I fasten it to the edge of the flat (instead of the face) by
means of rivets or wires or otherwise, the recess preventing the heads of the rivets or
the wires or other fastenings from projecting beyond the edge of the "flat" and these
will be protected from injury so that the surface of the "flat" is clothed with card
teeth to the full width thereof from edge to edge, and the endless chain or belt of
"flats" presents an unbroken card surface.
Or if preferred I use narrower "flats" each about the width of the strip of card
teeth on the flats at present used, by which means a greater number of "flats" can be
put on a chain or belt of a given length and the "flats" being narrower will turn
round the rollers with greater facility.

I JOHN ALLEN DYSON of Butler Street Mills, Manchester in the County of
Lancaster Manager 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 :—
The invention relates to the construction of the "flats " or flat cards used in
carding engines, and to the method of attaching or securing the wire and clothing
thereto; the object of the invention being to utilize the full width of the "flat" so as
to obtain an increased carding surface upon an endless chain of a given length.
And in order that my invention may be clearly understood I have annexed here-
unto a sheet of drawings illustrative thereof.
Fig. 1. is a plan view and Fig. 2 a side elevation of part of a "flat" made according
to my invention.
Fig. 3. is a section through three "flats" together in working position.
Hitherto the card clothing for flats has been made the full width of the "flat" but
with a blank margin at each edge for fastening or attaching the clothing to the face of
the "flat" by rivets or by wires or otherwise and the consequence has been that a
large amount of carding surface has been lost equal to double the width of this margin
between each two "flats."
:
According to my invention I make the card clothing a, a for "flats" wider than
the face of the "flat" b, bitself the card covered surface being of the width of the
"flat" with a margin outside upon each edge. I make the edge of the "flat" with a
recess at *
and I turn over the margin of the card clothing at each edge and
I fasten it to the edge of the flat if made of wood or to the flanges as shown if made
of cast iron (instead of the face) by means of rivets e, c or wires or otherwise the
recess preventing the heads of the rivets or the wires or other fastenings from
projecting beyond the edge of the "flat" and protecting them from injury so that the
surface of the flat is clothed with card teeth d, d to the full width thereof from edge
to edge or nearly so, and the endless chain or belt of "flats" presents an almost
unbroken card surface.
Or if preferred I use narrower "flats" each about the width of the strip of card
teeth on the flats at present used, by which means a greater number of "flats "can be
put on a chain or belt of a given length and the flats being narrower will turn round
the rollers with greater facility.

page_text: I prefer to strengthen the card clothing (by means of strips of tape e, e or other
suitable material, see Fig. 2) where the rivets pass through the same, as indicated also
by dotted lines at Figs. 1. and 3.
I also make the ends of each flat bb somewhat wider than the central part as shown
at x, x (Figs. 1. and 2) so that the parts bx, x may work close together, but to
prevent the rivet heads c, c and the card clothing on adjacent flats from coming into
contact with one another.
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 :-
:-
The construction and clothing of "flats" for carding engines substantially in the
manner hereinbefore described and illustrated by the annexed drawings.
