PROVISIONAL SPECIFICATION.
Improvements in Mountings for Carding Engine Flats, and in
Fasteners for Securing Card Clothing thereto.
I, EDMUND TWEEDALE of Globe Works, Accrington, in the County of Lancaster,
Manager, do hereby declare the nature of this invention to be as follows:-
This invention consists of an improved metallic mounting, or covering for enclosing
the raw, or cut edges of the foundation of the fillet, also of an improved fastener to be
employed in combination with the metallic edging, the latter however may be employed
in combination with the pins, rivets, and other well known fasteners heretofore
employed.
According to this my said invention I employ a strip or strips of metal, preferably
of mild, or soft steel, rolled stamped, or pressed to the form of the letter C which
receives, encloses and grips the raw edges of the cut woven foundation-The outer
upper edges of the bar are bevelled off or recessed, on or in which the under surface
of the C metal strips rest. Under the bar is a longitudinal rib as described in the
specification of Letters Patent, No. 1121 granted to me, and dated the 25th day of
January 1888.
The improved fastener for securing the foundation to the bar consists of a strip of
metal.in the form of the letter T the upper part of the fastener being curved or bent
so as to lie close upon, and grip the foundation and C metallic clip its lower end being
bent in the form of a hook-These fasteners are applied at intervals of the length of
the bar, and to provide for the reception of the fasteners, and to keep its surface flush
with the metallic C edgings I either cut away the back portion of the C forming a
recess for reception of the fasteners, or I apply the C metallic edgings in a series of
lengths equal to the width of the fastener. The improved fasteners are readily applied
by hand along one edge, then by means of a pair of hand clamps, the upper jaw of
which presses on the T head of the fastener the under jaws gripping the rib, and by
the leverage the card clothing is stretched across the face of the flat when applying
the foundation to the other edge and the hooked lower end of the T fastener slips
round the rib under the bar, and the whole is secure.
In combination with the metallic edging of the clothing there may be employed for
securing the same to the bar ordinary rivets, pins, or staples, but I prefer the improved
T shaped fastener hereinbefore employed.

COMPLETE SPECIFICATION.
Improvements in Mountings for Carding Engine Flats, and in
Fasteners for Securing Card Clothing thereto.
I, EDMUND TWEEDALE of Globe Works, Accrington, 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 :-
:-
My invention consists of an improved metallic mounting or covering for enclosing
the raw or cut edges of the foundation of the fillet or clothing combined with a
"flat" bar having bevelled or recessed edges for purpose hereinafter set forth,
and means for fastening or securing the latter when so encased to the bar of the flat.

page_text: According to my invention I employ a strip or strips of metal preferably of mild
or soft steel rolled, stamped or pressed into C shape which receives, encloses and grips
the raw edges of the cut woven foundation, while the fastening device I employ
consists of double hooked pieces of metal of Ṭ shape one hook of which engages with
a rib formed on the underside of the bar of the flat while the other hook formed of
the head of the T secures its hold partly upon the metal edging and partly upon the
woven foundation or clothing a number of such fasteners being placed at intervals
along both sides of the bar.
-
Such being the nature and object of this my said Invention, the following is a
complete description of same reference being had to the accompanying drawings :-
Fig. 1 is an elevation of a portion of a card flat with my improvements applied
thereto.
Fig. 2 is a section of same on the line x―x fig. 1.
Fig. 3 is a plan of fig. 1.
Fig. 4 is a plan view of the card clothing only showing the encased edge.
Fig. 5 is a similar section of the flat to fig. 2 but showing one of the fasteners
about to be applied with a tool for that purpose.
Fig. 6 is a plan view of the flat and the tool.
The bar a of the flat has two ribs -b formed upon the underside of its head, as
described in specification of Letters Patent dated the 25th January 1888 No. 1121
while its upper surface is bevelled off or recessed, the object of the bevelling off or
recessing is to provide for the extra thickness of the edges of the foundation by
reason of the metal edgings so that the clothing lies flat to the face of the bar and its
metal encased edges are not too prominent at the points
cc as shewn.
The card clothing e has its edges encased and enclosed by the C shaped metal
strips ff which are applied in any convenient manner. These strips may be either
continuous and have notches g g (fig. 4) cnt therein for the reception of the fasteners /
or they may be applied in lengths as shewn at the right hand end of fig. 4 suitable
spaces being left between them for the same purpose. These notches gg or spaces
enable the fasteners h to lay flush with the side of the metal edging f. The fasteners /
consist of shaped metal double hooks as shown, the upper hook of which bears
upon the foundation and upon the metal edging while the lower hook engages
with the ribbon the underside of the bar a of the flat, the metal edgings of the
card clothing being drawn down and partly seated in the bevels c-c on the edges of
the bar.
In fig. 5 I have shewn the method of applying these fasteners with a tool for the
purpose, the latter consists of a pair of tongs having a single upper jaw i with a
ridge or tooth on same (which may be serrated if desired) and a pair of lower.
jaws jj cut away or recessed to form shoulders as shown. The upper hook of the
fastener being placed on the metal edging as shewn in fig. 5 the jaw i of the tongs
is placed upon same while the lower jaws take hold of the rib on either side
of the lower hooked end of the fastener which upon pressure being applied to close
the jaws and slight leverage will draw and stretch the clothing tightly over the face
of the bar of the flat and enable the operator to slip the lower hooked end of the
fastener around the rib band the operation is completed.
The metal edging strips ff may however be employed with the ordinary pins,
rivets, staples, or other fasteners as they serve to prevent the edges of the clothing
fraying away but I prefer to use the T form of fasteners shown and described.
Having now particularly described and ascertained the nature of this my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
1. A metal strip or edging for enclosing and encasing the raw edges of card
clothing in combination with the bar of a flat having its upper edges g g bevelled or
recessed substantially as described.

page_text: 2. In combination a metal strip or edging for enclosing and encasing the edges
of card clothing applied in lengths or having notches g g with double hooked metal
fasteners adapted to grip said strips or edging and the card flat substantially as
described.
