PROVISIONAL SPECIFICATION.
Attaching or Securing Card Clothing to the Flats of Revolving
Flat Carding Engines.
We, JOHN WILLIAM FAWCETT, Gooder Lane, Rastrick, Engineers Fitter,
and ERNEST JONES, of Whitcliffe, Cleckheaton, Card Nailor, both in the County
of Yorkshire do hereby declare the nature of this invention to be as follows
Our invention relates to an improved clamp or fastener, for the purpose of
attaching or securing card clothing to the flats, which form an endless chain on
revolving flat carding engines, without planeing or altering in any way the
flats from the original flats, which have holes drilled through the outer edges, as
is well understood.
The clamp or fastener consists of a US strip of metal of the required
length, having legs or prongs, formed on or from the under side of the strip.
These legs are bent at right angles to the said strip, and are at such a distance
apart as to suit circumstances. "The foundation of the card clothing is cut to the
required width and the edges are then placed in the said > strip, which is then
pressed rolled or hammered tightly on to the fabric, the upper or both sides of the
strip being perforated, or toothed, so as to hold the clothing more securely. Still,
we do not bind ourselves to perforate, or tooth, the strip in any way, as the
fasteners will hold securely without. The clothing and fasteners are then placed
on the face of the iron flat, the legs or prongs being forced downward through
the holes in the said flat. The legs being of such a length as to project through
on the under side. The fasteners and clothing being pressed or rolled tightly on
to the face of the flat, the projecting ends of the legs are then folded down on the
under side, thus securely holding the clothing in position. In order that the
clothing may be tightly stretched across the face of the flat, it is cut to such a
width, that when the fasteners are attached, the distance between the legs is not
so wide as the holes in the flat.
Our improvement is such, that in necessary cases the fasteners may be attached
to the clothing before being sent to the factory where the flats are working. Thus
saving the time that is at present lost in sending the flats away to be recovered.

COMPLETE SPECIFICATION.
Attaching or Securing Card Clothing to the Flats of Revolving
Flat Carding Engines.
We, JOHN WILLIAM FAWCETT, of Gooder Lane, Rastrick, Engineers' Fitter,
and ERNEST JONES, of Whitcliffe, Cleckheaton, Card Nailor, both in the County
of York, 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 improvements consist in making a clamp or fastener with a C shaped groove
and projecting prongs to be used for taking hold of card clothing and attaching same
to the revolving flats of carding engines.
In commencing to put the parts together our improved clamps are first of all
attached to the card clothing, and afterwards the cards so clamped, are attached
to the flats, either new ones, or those at present in use having holes in their outer

edges, and this can be done without in any way altering the said flats, as our
improved clamp is made with prongs which can be inserted into the holes drilled
into the said flats.
Such being the nature and object of our invention, we will now proceed to
describe the same more fully, and for that purpose make reference to the accom-
panying sheet of drawings illustrative thereof, wherein Fig. 1 is an edge view of
our improved clamp, one of which is attached to each side of the card ready for
being applied to the flat or sent to the factory; Fig. 2 is a view looking on the
underside of one of our clamps; Fig. 3 shews the method of how our clamp secures
the card clothing of the flat, and Fig. 4 is a view on the underside of Fig. 3.
A is a cross section of the flat, and B the card clothing; our improved clamp is
shewn at C, which is made of any required length.
The clamps have shaped grooves and are made with legs or prongs D which
do not pass through the card clothing, but are inserted through holes formed in
the edge of the flats, the prongs being afterwards bent over after the manner of a
paper fastener as shewn clearly in Fig. 4. Preferably the upper edge of the
clamp is serrated as shewn at E so that when pressed onto the upper side of the
card clothing B, the clamp more securely holds the card clothing in position.
After the clamps have been fixed to the card clothing, the clothing itself will be
stretched on being attached to the flat, and this is done in the following manner
viz. The card is made slightly narrower than the width of the flat, and on
commencing to fix the card to the flat, the card is bent so as to be slightly concave
as shewn at Fig. 5, causing the prongs to incline outwardly, the points of which
are then inserted into the holes at the edge of the flats, and on the prongs being
forced down, they are made to become vertical, in doing which they act as levers
drawing the card outwardly or broader, whereby the card clothing is stretched upon
the surface of the flat.
Our improved clamps are specially adapted to existing flats which have holes
bored in their outer edges, and our improved clamps possess another advantage
viz. That they can be fastened to the card clothing at the works of the card
maker, and afterwards sent to the factory and there secured to the flats; this will
be found a great convenience especially in the export of cards which can be sent
away with our clamps without the flats, and thus save freightage and custom
house duty.
We have not described any form of apparatus for making our clamps, nor have
we described any form of apparatus for pressing the C shaped groove onto the
card clothing, as these devices form no part of our invention, as the methods to
do which may be various, but
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 :--
Firstly. A clamp, having a C shaped groove and projecting prongs, the former
of which receives and is attached to the card clothing previous to and ready for
being applied to carding engine flats, all as described.
Secondly Mounting and securing card clothing upon carding engine flats by a
clamp having shaped grooves and projecting prongs as herein shewn and
described.
