Improvements in Means for Attaching Card Clothing to the "Flats"
Employed on Carding Engines.
We FREDERICK WHITLEY THOMSON of Brunswick Mills Halifax in the County of
York, Card Maker, and JOSEPH SEEL of Glen Dale, Plymouth Street Lower
Broughton, Manchester in the County of Lancaster, Engineer, do hereby declare
the nature of this invention to be as follows :-
The object of this invention is to construct a novel form of clip or clamp for
securing the card clothing to the "flats" employed on carding engines for carding
cotton or other fibrous substances, in such a way that the said clips can be applied to
the flats and removed therefrom for replacing the card clothing by an ordinary
mechanic without the use of any special machinery or tool other than an ordinary
turnscrew.
For this purpose we employ longitudinal metal strips bent into such a form as to
clip the edges of the strip of card clothing pass round the edges of the same and of
the flat, and extend partly round the back of the latter, but instead of making such
clamps or clips so tight that they require to be sprung on or to be bent or compressed
thereon by special machinery or tools as hitherto done we make the opening of such
a width that they can be easily passed over the edges of the flat and the clothing by
hand, and they are caused to nip the edge of the card clothing without being further
compressed.
The tightening of the clip or clamp is effected as follows:-
"
:-
The back of the "flat is provided with either a raised rib or a groove in such a
position that the edge of the clip which passes under or round the back of the "flat"
can rest against or in such rib or groove; and screwed holes are made at suitable
intervals through that part of the clip or clamp which passes under the "flat" into
which holes short screws are fitted.
The clip or clamp being placed with its upper edge over the edge of the clothing
and its under edge against the rib or in the groove above named, upon turning the
small screws, they will press against the back of the "flat" and using the rib or the
edge of the groove as a fulcrum will draw down the upper edge of the clamp, and
cause it to grip the edge of the clothing and hold it firm. A groove or indentation is
made in the back of the flat to receive the ends of the screws so that the clip cannot
be drawn off without loosening the screws.
By bevilling the edges of the flat the clamps will be caused to draw outwards'
and stretch the clothing as the screws are tightened. Or the same effect may be
produced by making a V-shaped groove near the edge of the face of the "Hat"
into which the upper bend of the clip or clamp is drawn as the screws are
tightened.

Improvements in Means for Attaching Card Clothing to the "Flats"
Employed on Carding Engines.
We FREDERICK WHITLEY THOMSON of Brunswick Mills Halifax in the County of
York, Card Maker, and JOSEPH SEEL of Glen Dale Plymouth Street Lower
Broughton Manchester in the County of Lancaster 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 :-
The object of this invention is to construct a novel form of clip or clamp for securing

page_text: the card clothing to the “flats" employed on carding engines for carding cotton or other
fibrous substances in such a way that the said clips can be applied to the "flats" and
removed therefrom, for replacing the card clothing, by an ordinary mechanic without
the use of any special machinery or tool, other than an ordinary turnscrew.
The nature of our said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the sheet of drawings hereunto annexed and the following explanation thereof.
Figs 1, 2, 3, 4 and 5 on the drawing represent in transverse section a metal "flat"
with the card clothing attached thereto by our improved means, the principle being
the same in all cases but the form slightly modified. a is the metal "Hat" and
6 the card clothing.
For the purposes of our invention we employ longitudinal metal strips c bent into
such a form as to clip the edges of the same, and of the "flat" a and extend partly
round the back of the latter, but instead of making such clamps or clips so tight that
they require to be sprung on, or compressed thereon by special machinery or tools as
hitherto done, we make the opening of such a width that they can be easily passed
over the edges of the flat and clothing b by hand and they are caused to nip the edge
of the card clothing b without being further compressed.
The tightening of the clip or clamp c is effected as follows:-The back of the flat is
provided with either a raised rib or a groove as shown on the various figs., in such a
position that the inner edge of the clip c which passes under or round the back of the
flat "
can rest against or in such rib or groove; and screwed holes are made at
suitable intervals through that part of the clip or clamp c which passes under the flat a
(see Figs. 1 and 2) into which holes short screws d are fitted.
The clip or clamp c being placed with its upper edge of the clothing band its
under edge against the rib or in the groove above referred to, upon turning the small
:screws they will press against the back of the "flat" a and using the rib or the
-edge of the groove as a fulcrum, will draw down the upper edge of the clamp c and
cause it to grip the edge of the clothing b and hold it firm.
A groove or indentation is made in the back of the flat a (Figs. 1 and 2) to receive
the ends of the screws d so that the clip c cannot be drawn off without loosening the
screws, and these grooves are so bevilled internally that the tightening of the screws
will force the clips c slightly outwards and thus stretch the clothing, and this action
inay also be assisted by bevilling the edges of the "flat" as shown at Fig. 1, or by
making a bevil shaped groove near the edge of the face of the "flat" as shown at
Fig. 2 into which the upper bend of the clip or clamp c is drawn as the screws d are
tightened.
On Figs. 3, 4, and 5 the screws d are shown as taking their abutment against the
-edges of the "flat" instead of against the back thereof.
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 :-
The improved means for attaching card clothing to the "flats" employed on carding
engines, consisting of loosely fitting metal strips or clamps one edge of which is
passed above the clothing on the face of the "flat," and the other edge is curved or
bent over the edge of the "flat" and rests in a groove or against a rib in or on the
back thereof, the said strips or clamps being tightened by means of screws or
equivalents abutting against the back or edges of the "flat" substantially as herein-
before described and illustrated by the drawings annexed.
