PROVISIONAL SPECIFICATION.
Improvements in Flats Employed in Carding Engines.
We EDWARD WRIGHT WRIGLEY of Thornycroft Werneth, Oldham, Lancaster
Cotton Spinner and ROBERT PATTERSON of 58 Greengate Street Oldham, Lancaster,
Manager do hereby declare the nature of our said invention to be as follows:-
This invention relates to an improved means of more effectually protecting and
supporting the carding wires at the edge of the card filleting forming the flat and in
that part technically called the heel of the flat.
In performing our invention we either reduce the length of the wires all along at
this edge and to the extent of about an eighth of an inch more or less in width or
employ wires of reduced length or we apply a solid metal strip of about the same
depth riveted or otherwise secured in the same position. We find that this means of
supporting the edge of the card filleting also gives a straighter and more parallel edge
to the carding wires than has hitherto been practicable.

COMPLETE SPECIFICATION.
Improvements in Flats Employed in Carding Engines.
We EDWARD WRIGHT WRIGLEY of Thornycroft Werneth, Oldham, Lancaster,
Cotton Spinner and ROBERT PATTERSON of Greengate Street, Oldham, Lancaster,
Manager do hereby declare the nature of our said 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 an improved means of more effectually supporting and
protecting the carding wires at the edge of the card filleting and forming the flat in
that part technically called the heel of the flat.
In performing our invention we either reduce the length of the wire all along at
this edge to the extent of about one eighth of an inch more or less in width or employ
wires of reduced length or we apply a solid metal strip of about the same depth
rivetted or otherwise secured in the same position. We find that this improved means
of supporting the edge of the card filleting also gives a straighter and more parallel
edge to the carding wires than has hitherto been practicable.
On the accompanying drawing Figs. 1 and 2 represent end sectional views of
carding engine flats embracing our improvements.
In performing our invention we either reduce the length of the wires forming the
card filletting at the heel edge a of the flat and to the extent of about an eighth of
an inch more or less in width as illustrated in Fig. 1. or we apply a solid metal strip b
of about the same depth and in the same position at the heel edge as illustrated in
Fig. 2. which strip is rivetted to the bar c or otherwise secured thereto in any suitable
manner.
We prefer that the inner edge of this metal strip shall be formed angular as illus-
trated so as only to be in touching contact with the onter wires for the smallest possible
surface but it will be obvious that other sections or strips of metal or other suitable
material might be substituted with more or less advantage,
