PROVISIONAL SPECIFICATION.
Improved Apparatus for Securing Card Clothing to the Flats of
Carding Engines.
We GEORGE ALEXANDER KENNEDY of the Firm of Horsfall & Bickham
of Bridgewater Works Pendleton in the County of Lancaster Card Makers,
WILLIAM SENIOR and IRA Wood both of the same place, Mechanics, do hereby
declare the nature of this invention to be as follows:-
This invention relates to apparatus for securing card clothing to the flats of
carding engines by means of strips of metal provided with a flange which is itself
formed or provided with teeth or spikes passing through the foundation of the
clothing from beneath; and the object of the invention is to provide convenient
and efficient apparatus for pushing the teeth or spikes through the clothing,
rivetting or clinching them down on the surface thereof, covering the clinched
points by bending the upper part of the metal strip over the edge of the clothing
and finally securing the whole to the flat by bending the lower part of the strip
beneath the edge of the said flat.
According to this invention we mount upon a suitable frame a pair of long bed
plates each having a vertical face and a horizontal face. These vertical faces are
about the distance of the width of the flat apart from each other; but we would
here remark that only one bed plate might be used although we prefer to employ
the two as above described so that both edges of the flat can be secured at the
same time by two attendants at the same machine.
The horizontal and vertical faces of the bed plate are made with a number of
bolt holes for securing loosely a horizontal and a vertical plate, the former being a
pressing and clinching plate and the latter a clamping plate as hereafter described.
The heads of the bolts for securing the clamping plate are so formed or made
that it can rock slightly thereon as on a horizontal pivot and the plate is provided
near its lower edge with a flange or is otherwise so formed that it can be acted
upon by a long eccentric rod or rocking shaft moved by a suitable handle or lever
to force out the lower edge of the clamping plate and bring in the upper edge
against the vertical face of the bed plate. The lower part of the metal strip above
named (which forms the fastener) being placed between these plates with its flange
resting (spikes upwards) upon the upper edge of the clamping plate the said
fastener will be firmly held in place. A fastener being so clamped to each bed
plate there will be exactly sufficient room between them to place a strip of card
fillet between the two fasteners and rest it upon the spikes.
The pressing plate then comes into action. It is slotted so that it can slide upon
the bolts which secure it to the bed plate, and is pushed forward by an eccentric
rod or rocking shaft working against its outer edge and moved by a suitable handle
or lever. Its outer edge is then raised by another eccentric rod or shaft beneath
it, and it rocks upon its bolts the head of each of which is made with a half_ball
working in a socket in a thick washer or loose plate through which it passes.
the inner edge is brought down upon the card clothing forcing it down upon the
flange of the fastener and causing the points or spikes to project up through the
face of the said clothing.
Thus
The points or spikes are then bent down upon the face of the foundation of the
clothing by means of a small roller or bowl at the end of a suitable handle; this

page_text: bowl is preferably made with a groove in its periphery in which fits the upper edge
of the fastener so that the tool is guided thereby along the edge of the clothing
and thus none of the points or spikes are missed.
The latter are then completely clinched by placing a rod along the edge of the
clothing upon the bent over spikes and bringing over and pressing down the
clinching plate.
Another rolling tool made conical on its periphery is then passed along the edge
of the clothing between the vertical face of the bed plate and the upper edge of
the fastener, bending the latter over the edge of the clothing. The pressing and
clinching plate is then brought down again and completely covers the clinched ends
of the points or spikes by pressing the aforesaid upper part of the fastener down
upon them.
Each edge of the clothing having been secured as above described to a fastener
strip, the same can now be secured to the flat either in another similar machine
or by removing the clamping plates and substituting fixed ones.
In either case
the said fixed plates must allow sufficient space above their upper edges for the
edges of the flat to come beneath the pressing and clinching plates. The upper
edges of the fixed plates are by preference slightly grooved or hollowed to receive
the metal edging formed by the bent over edges of the fasteners, the card clothing
being placed upon these two plates face downwards and resting upon their upper
edges; the other edges of the fasteners which now project upwards are bent over
the edges of the flat (which is placed downwards on the card clothing) by a
runner tool or otherwise, and the pressing and clinching plate is brought down,
pressing the edges of the fasteners down upon the under surface of the flat and
thus securing the fasteners and consequently the card clothing firmly to the flat.

Improved Apparatus for Securing Card Clothing to the Flats of
Carding Engines.
We GEORGE ALEXANDER KENNEDY of the Firm of Horsfall & Bickham
of Bridgewater Works Pendleton in the County of Lancaster, Card Makers,
WILLIAM SENIOR and IRA WOOD both of the same place, Mechanics, 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 apparatus for securing card clothing to the flats of
carding engines by means of strips of metal provided with a flange which is itself
formed or provided with teeth or spikes passing through the foundation of the
clothing from beneath, as shewn by the Specification of Letters Patent No. 8407
granted to William Senior and others, dated April 26th 1893, and the object of the
invention is to provide convenient and efficient apparatus for pushing the teeth or
spikes through the clothing, rivetting or clinching them down on the surface thereof,
covering the clinched points by bending the upper part of the metal strip over the
edge of the clothing and finally securing the whole to the flat by bending the lower
part of the strip beneath the edge of the said flat.
Our invention will be readily understood from the following description on
reference to the two accompanying sheets of drawings.
Fig. 1 is a plan view, and Fig. 2 a transverse section of a machine adapted to be
used for the entire process as hereafter described.

page_text: Fig. 3 is an end view illustrating the apparatus to be employed for the final part
of the process as hereafter described.
Figs. 4, 5, 54, 5, 6, and 7 are detached views hereafter more particularly
referred to.
According to this invention we mount upon a suitable frame a pair of long bed
plates a a (Figs. 1 and 2) each having a vertical face and a horizontal face
(see Fig. 2). These vertical faces are about the distance of the width of the flat
apart from each other, but we would here remark that only one bed plate might be-
used although we prefer to employ the two as above described so that both edges
of the flat can be secured at the same time by two attendants at the same
machine.
The horizontal and vertical faces of the bed plate are made with a number of
bolt holes for securing loosely a horizontal plate b and a vertical plate c, the former
being a pressing and clinching plate, and the latter a clamping plate as hereafter
described.
The heads of the bolts or screws c¹ for securing the clamping plate are so.
formed or made (see Fig. 2) that it can rock slightly thereon as on a horizontal
pivot, and the plate c is provided near its lower edge with a flange, or is otherwise
so formed (or mounted as seen at Fig. 2), that it can be acted upon by a long
eccentric rod or rocking shaft d moved by a suitable handle or lever d¹ (Fig. 1) to
force out the lower edge of the clamping plate c, and bring in the upper edge
against the vertical face of the bed plate a. The lower part of the metal strip
above named (which forms the fastener) being placed between these plates a and c
(see detached view Fig. 4) with its flange a resting (spikes upwards) upon the
inner edge of the clamping plate c the said fastener will be firmly held in place..
A fastener being so clamped to each bed plate (see Fig. 4) there will be exactly
sufficient room between them to place a strip of card fillet on the two fasteners.
and rest it upon the spikes.
The pressing plate 6 then comes into action. It is slotted (as seen at Fig. 2) so.
that it can slide upon the bolts 6' which secure it to the bed plate a, and is pushed
forward by an eccentric rod or-rocking shafte working against its outer edge and
moved by a suitable handle or lever e¹, see also Fig. 1. Its outer edge is then.
raised by another eccentric rod or shaft beneath it, and it rocks upon its bolts,.
the head 62 of each of which is made with a half ball working in a socket in, a
thick washer or loose plate through which it passes (see Fig. 2). Thus the inner
edge which is formed for the purpose, as seen at Fig. 4, is brought down upon the
card clothing forcing it down upon the flange x' of the fastener x, and causing the
points or spikes to project up through the face of the said clothing.
The points or spikes are then bent down upon the face of the foundation of the
clothing by means of a small roller or bowl g (shewn detached at Fig. 54) at the end
of a suitable handle or in a frame g¹ provided with handles 92 (see side and end
views Figs. 5 and 6); this bowl 9 is preferably made with a groove g+ in its
periphery in which fits the upper edge of the fastener so that the tool is guided
thereby along the edge of the clothing and thus none of the points or spikes are
missed. The frame is guided and held down by the bowls 98 thereon which run
beneath plates g' fixed upon the plates 6 (Fig. 2).
The latter may then if desired be completely clinched by placing a rod along
the edge of the clothing upon the bent over spikes and again bringing over and
pressing down the clinching plate b. This clinching may however be dispensed
with.
Another rolling tool 9 shewn detached at Fig. 5B made conical on its periphery
and mounted behind the bowl g in the frame g¹ follows the said bowl g and passes
along the edge of the clothing between the vertical face of the bed plate a and the
upper edge of the fastener, bending the latter over the edge of the clothing. The
pressing and clinching plate b is then brought forwards and down again and com-
pletely covers the clinched ends of the points or spikes by pressing the aforesaid
upper part of the fastener down upon them.

page_text: Each edge of the clothing having been secured as above described to a fastener
strip, the same can now be secured to the flat either in another similar machine (as
seen at Fig. 3) or by removing the clamping plates c and substituting fixed ones.
In either case the said fixed plates c+ must allow sufficient space above their
upper edges for the edges of the flat to come beneath the pressing and clinching
plates (see Fig. 7). The upper edges of the fixed plates c+ are by preference
slightly grooved or hollowed as shewn to receive the metal edging formed by the
bent over edges of the fasteners x, the card clothing being placed upon these two
plates face downwards and resting upon their upper edges.
The plate + the inner edge of which is formed by preference with a groove as
shewn, is then brought down over the projecting edges of the fasteners and the
bed plate shewn on the left hand side of the machine is drawn back by the
excentrics (see also Figs. 1 and 2) and the card clothing is thus stretched.
The flat is then placed between the metal edges face downwards upon the clothing
and the movable bed plate is returned to its place, see Fig. 7. The plate b+ on
each side of the machine is then forced inwards and will bend the edges of the
metal strips over the under side of the flat; and the plates 6+ being then brought
down to press the edges of the fasteners upon the under surface of the flat will
thus secure the fasteners and consequently the card clothing firmly to the flat.
a runner tool may be used to bend over the edges of the metal strip ready to be
pressed down by the plates b.
Or
It will be seen that by the use of this apparatus the clothing can be stretched
before the flat is put upon it and when secured to the edges of the flat will be held
in this stretched condition and as the spikes of the fastener pass through the
clothing from the side next to the face of the flat there will be no tendency for the
said clothing to rise in the middle of its width but the clothing will be held perfectly
level and smooth on the flat.
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 :-
1. The construction and arrangement of apparatus for securing the above named
card fasteners to the card clothing and to the flats of carding engines substantially
as hereinbefore described and illustrated by the annexed drawings.
2. The construction and arrangement of apparatus for securing the above
named card fasteners to the card clothing substantially as hereinbefore described
and illustrated by the drawings annexed.
3. The construction and arrangement of apparatus for bending the edges of the
fasteners attached to the clothing to secure the same to the flat substantially as
herein before described and illustrated by the annexed drawings.
