Improvements in Flats and in Fasteners for Securing the Card
Clothing thereon and 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 relates to the flats employed on flat carding engines and in the
fasteners employed for securing the card clothing to the said flats.
I cast or form on the under surface of each side of the bar of the flat a longitudinal
rib, or tongue. The fastener consists of a strip of metal of the required length. One
of its edges is rolled, stamped, or pressed so as to form a three sided recess—the mid-
portion of the strip is flat, and the outer or remaining edge is cranked or bent at
right angles to the plain or flat part, the two foldings of the strip, make one half into
a shape not unlike the letter (U) 5, whilst the remaining half of the width, is of
Jform. The U edge of the fastener, receives the edge of the foundation, of the
clothing within which it is tightly gripped, the edge of the upper part of the > being
toothed or serrated, and the under part may be perforated so that when the > is closed
tightly on the foundation, the serrations enter or grip the face of the clothing whilst
pressure causes the under surface of the foundation to enter the perforations whereby
the foundation is gripped and firmly held-The clothing and fasteners, are next laid
on the flat, the straight or flat remaining part of the fastener lies to, and along the
edge of the flat, whilst the remaining portion, will be turned under the flat, and around
the longitudinal rib or tongue, in a Jor hook form thus securing the edge of the
fastener to the bar.
The width between the fasteners, is slightly less than the width of the flat so that the
foundation, is, in the operation of putting on, and creasing over the other or lower
edge of the fastener over the rib or tongue tightly stretched, and evenly and securely
held in position.

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 :-
This Invention relates to the flats employed on flat Carding Engines and in the
fasteners employed for securing the Card Clothing to the said flats.
In carrying out my Invention I cast or form on the under surface of each side of the
bar of the flat a longitudinal rib or tongue or projecting portion, so as to afford a
means of retaining or securing the bent over edge of a strip of sheet metal as herein-
after described. The fastener consists of a strip of sheet metal of the required length,
one of its edges is rolled stamped or pressed, so as to form a three sided recess the mid
portion of the strip is flat, and the outer or remaining edge is cranked or bent at right
angles to the plain or flat part the two foldings of the strip, make one half into a shape
not unlike the letter (U), whilst the remaining half of the width is of form. The
U edge of the fastener receives the edge of the foundation of the clothing within
which it is tightly gripped, the edge of the upper part of the may be toothed or
serrated and the under part may be perforated so that when the > is closed tightly on
the foundation, the serrations enter or grip the face of the clothing whilst pressure
causes the under surface of the foundation to enter the perforations whereby the
foundation is gripped and firmly held. The clothing and fasteners are next laid on
the flat the straight or flat remaining part of the fastener, lies to and along the edge of
the flat, whilst the remaining portion will be turned under the flat, and around the
longitudinal rib or tongue or projecting portion in a J or hook form, thus securing
the edge of the fastener to the bar.
The width between the fasteners, is slightly less than the width of the flat, so
that the foundation is, in the operation of putting on, and creasing the other or
lower edge, of the fastener, over the rib or tongue, tightly stretched, and evenly,
and securely held in position.
Such being, the nature and object, of this my said Invention, the following is
a complete description of the same, reference being had, to the accompanying
drawings, in which Figs. 1. 1 and 2, illustrate the metal strip, from which the
fastener is to be made, and 3. 4. 5. the several forms, to which it is bent or folded, in
making, and applying the complete fastener.
Fig. 6. shows the fastener, applied to the edge of foundation, of the fillet.

serrated gripping edge, and perforations.
Fig. 13. illustrates like fastener, having plain or nonserrated gripping edge, and
without perforations.
The several figures 14. 15. 16. 17 illustrate appliances, for shaping and applying the
fasteners.
Fig. 18. is a view, explanatory of the mode of stretching, the clothing, on the bar.
employ a strip of sheet metal, such as shewn at Figs. 1. and 2. of the
required length, and width, this strip is placed hetween the jaws 2. 3. Figs. 14.
the upper jaw by means of the screw 4. being forced down, upon the strip, folds
it, to the form illustrated by Fig. 3.
The Card fillet 5. Fig. 15 is placed between the jaws 6. 7. and the parts 8. 9.
of the foundation, are held firmly in position, by the bolt 4ª.
The outer surface, or sides of the jaws 6. 7. being smooth, and true, form or
guage, to which the "foundations" 5. are, by knife, cut all to the same width, as
this guage, whereon the upper jaw 6, is removed, and the fillet is lifted from the
lower jaw 7, and placed with the under surfaces of its edges, upon the shoulders,
of two of the strips, of the shape shewn, at Fig. 3. which had been previously made,
in the appliance illustrated by Fig. 14, and placed in the appliance Fig. 16, and
then the jaws 11ª, folding on the joints, A. B. will be nipped together, by the
nut and bolt 11, to the T head, 11 which forms a guage, whereon the presser
jaw 10. will by the screws 11. be forced down, folding the part A: of the fastener,
to the form shewn at Figs. 6, and 16, and securing the fastener, to the edges of
the foundation 5.
The fastener, and Card filleting, are now in the condition, shown by Fig. 6, and
they are next to be placed, with the wire downwards, as illustrated by Fig. 17,
on the supporting die 12. The bar 13. of the flat, will then be placed, as shewn,
with its upper surface, on the back of the Card clothing, on which it will be
pressed firmly, through the action of the screw 14, bearing on the presser piece 15,
at the same time, producing the necessary stretching of the foundation, or Card
filleting, as shewn in Fig. 18, where the bar is figured, as entering between the
upright portions, of the metal sheets 1. 1. and as the bar 13, is slightly wider than the
distance between the metal sheets, when pressed between them, produces, the requisite
amount of stretching or tension, of the foundation 5, and Card filleting.
The jaws 19, are then folded or closed, on hinges 20, and the parts 193, of the
jaws 19, are then brought, to bear firmly against the straight or upright parts of the
metal sheets 1. 1. and pressing such parts, closely to the edges of the bars, or flats, by
the use of the bolt 21. The bar, 13, fastener, and Card clothing, being thus securely held,
the slide pieces 16, will by the screws 17, be forced downwards, pressing outwards,
and folding the upper portion, of the straight part of the fastener, to, and over the
longitudinal ribs or tongues. 18, in a hooked, or J form, which hold the fastener, and
clothing, in true position see Figs. 8. 10. and 13. The slide pieces 16, are carried in
the jaws 19, the latter being capable of folding outwards, on the centres 20, for
purpose of facilitating, the placing of the fillet, fastener, and bar, in position, for
being operated upon, as described, and for removal therefrom.
Each strip 1, from which a fastener is to be made, is preferably, the length of
the whole working surface of the bar, of the flat, and I so manufacture, and apply
the fasteners, though they may be made, in two, or more lengths, so likewise, in
reference to the longitudinal ribs 18. I employ the latter along the whole length
of the bars, but such ribs would be useful, if along the bar, in a series of lengths,
and blanks, though not so effective, as if continued the whole length of the bar.
It will be seen, that I have thus provided, a method, of attaching the foundation,
to the bar, by the use of a continuous sheet of bent metal, (without the use of
ordinary rivets, pins, prongs, or other fastening devices, as heretofore, employed)
whereby, the edges of the foundation, all along the surface, and its edges, as also

page_text: the edges of the bars, of the flat, are enclosed, and encased, by the continuous
fastener, so that there can be no, puckering, or fraying of the edges of the
foundation, and so that the boring, or nicking the edges of the bars, for the receipt of
the rivets, pins, or prongs of the fasteners, and puncturing the foundations, as
heretofore employed, is no longer necessary, the bending over, of the edges of
the strip, being sufficient, to grip, and secure the foundation, to the bar, whilst
at the same time, enclosing, and encasing the cut edges of the foundation, and
edges of the bar, so as to present, an even, surface, throughout, whereby all puckering
or fraying of the cut or raw edges of the foundation, is avoided and there is a
great saving of labour, heretofore expended, in boring the bars and applying the
fasteners, and furthermore, a highly improved appearance, and finish is given to
the flats.
I would observe, that the serrating the edges, and the perforating, as illustrated
at Fig. 12, whilst affording, increased gripping, are not indispensible, as I have
obtained practical, and satisfactory results, from fasteners, neither serrated, nor
perforated.
I have now described, means, whereby, I can effectually carry out, my invention,
but I would remark, that it is obvious, that the forms of the edges of the bars,
and of the bent portions of the strip, may be varied, without departing from the
principle of my Invention, so long as it is provided, that one edge of the strip,
secures a firm grip upon the foundation, at the same time that the other edge,
also secures a tight grip upon the under portion of the bar, so that extraneous
rivets, nails, or prongs, can be dispensed with.
Having now particularly described, and ascertained the nature of my said Inven-
tion, and in what manner, the same is to be performed, I declare that what I
claim is :-
1. The improved construction of fastener, whereby the Card fillet, is secured to
the bar, along the edges, or selvages of the foundations, which edges, or selvages,
and also, the edges of the bars, are enclosed, and encased, by the fastener, as
described, and illustrated by the annexed drawings.
2. The improved construction of fasteners, combined, with the longitudinal ribs,
or tongues, or projections, as herein described, and illustrated by annexed drawings.
