We GEORGE ASHWORTH and ELIJAH ASHWORTH of the firm of Ashworth Brothers
of the Moss Brook Works Collyhurst Manchester in the County of Lancaster
Engineers do hereby declare the nature of this Invention to be as follows:-
Our Invention relates principally to the flats used in travelling flat carding engines
and consists of improvements in a former invention for which Letters Patent
number 4091 of the year 1877 have been granted to us. In carrying our said former
invention into effect we secured the clothing to the flat bar by means of metal staples
which passed through slits or perforations in the bar and were clenched on the back of
the bar. According to our present invention we use a multiple staple or fastener
baving a number of legs to pass through the slits or holes in the bar and formed by
slitting a riband of metal or flattened wire with rectangular cuts which partially sever
narrow strips of metal these strips remaining attached to the riband by one end. The
said strips are bent at right angles to the riband in the slitting operation or by a
subsequent operation to constitute the said legs and are spaced at distances apart corre-
sponding to the pitch of the slits or holes in the bar. The metal riband so prepared
is applied with the said legs passing through the material and the slits or holes in the
bar and the parts are clamped together by pressing the parts together and by bending
over or clenching the ends of the legs. The said legs are each formed either by
means of two slits or cuts extending in the direction of the length of the riband and
united at one end by a cross cut or of one slit and a cross cut opening out at one edge
of the riband. In the former case the riband may be wider than in the latter so that
if desired it may extend from the edge of the bar entirely to the dents of the card
and thereby cover the margin of the foundation. In the ordinary practice of attaching
by means of rivets there is a tendency for the cloth of the foundation to pucker at the
intervals between the rivets especially when woollen material is used in the founda-
tion. This constitutes an important defect as the whole of the heels of the dents do
not properally bed upon the flat bar and the margins are liable to collect fluff and
dirt. To remedy this defect we cover each margin with a riband or strip of steel or
flattened wire or of sheet metal which has been perforated to correspond with the
holes drilled in the bar and we secure the whole together by means of rivets or of
suitable fasteners.

We GEORGE ASHWORTH and ELIJAH ASHWORTH of the firm of Ashworth Brothers
of the Moss Brook Works, Collyhurst, Manchester, in the County of Lancaster,
Engineers, 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 and accompanying drawings:
:-
Our Invention relates principally to the flats used in travelling flat carding engines
and consists of improvements in a former invention for which Letters Patent number
4091 of the year 1877 have been granted to us. In carrying our said former inven-
tion into effect we secured the clothing to the flat bar by means of metal staples
which passed through slits or perforations in the bar and were clenched on the back of
the bar. According to our present invention we use a multiple staple or fastener
having a number of legs to pass through the slits or holes in the bar and formed by
slitting a riband of metal or flattened wire with cuts which partially sever narrow
The said
strips of metal these strips remaining attached to the riband by one end.
strips are bent at right angles to the riband in the slitting operation or by a subsequent
operation to constitute the said legs and are spaced at distances apart corresponding to
the pitch of the slits or holes in the bar.
Our Invention will be best understood when described more fully with reference to the
accompanying drawings which are drawn larger than the full size for sake of distinc-
ness. In the said drawings Fig. 1 represents a short length of a riband of steel which
has been slitted in accordance with our invention. The said riband is by preference
produced by flattening or rolling down steel wire as by that means smoother edges are
obtained than when strips are sheared from sheet metal to produce the ribands. The
lines at a indicate one of the forms in which the slits may be made. We do not
confine ourselves to any particular form of slit so long as the slit partially severs a
tongue of metal from the riband of such a form as will be suitable to the fastening of
the card clothing to the flat bars. The slitting may be effected by the action of
suitably shaped punches and dies fixed and mounted in presses or of revolving
punches and dies or by any suitable means the means for effecting the slitting not
forming any part of our invention. Each tongue remains connected by one end with
the metal riband and is bent at right angles with the face of the riband so as to appear
as in Fig. 2 which represents an edge view of the riband with the tongues constituting
a number of legs b b which project downward. In Fig. 1 the said tongues are about
in the centre line of the riband but they may be nearer to one edge as in Fig. 3 or
be close to one edge as in Fig. 4 wherein the tongues are supposed to be formed by
means of slits which open out at one end to one edge of the riband. When employing
the metal ribands so formed we apply the riband upon the margin of the foundation
material of the flat so that the said legs shall pass through the slits or holes formed in
the metal bar and project for a suitable distance beyond the back of the bar. The
projecting ends of the legs are then pressed or hammered down upon the back of the

page_text: bar and the parts are pressed together so that the card becomes tightly clamped to the
bar. Fig. 5 represents a cross section of a flat having the improved fasteners applied
in position. On the right hand side the legs appear as when first inserted. On the
left hand the parts are shown as when the fastening is completed. In the example
the bar is supposed to be nicked or slitted at the edges to receive the legs in
accordance with our said former invention. The riband indicated at c is made
sufficiently wide to cover the margin from the edge of the bar nearly to the wires.
When the bars are drilled to receive the legs the riband is formed with the legs at a
distance from one edge and at a distance apart to suit the positions of the holes in the
bar or otherwise the bar is drilled to suit the riband. Although we prefer that the
riband shall extend nearly across the margin of the card as in Fig. 5 we do not confine
ourselves to this. The riband illustrated by Fig. 4 is adapted to be used so as to
cover the edge of the margin without extending so nearly to the wires of the cards.
In the ordinary practice of attaching by means of rivets there is a tendency for the
cloth of the foundation to pucker at the intervals between the rivets especially when
woollen material is used in the foundation. This constitutes an important defect as
the whole of the heels of the dents do not properly bed upon the flat bar and the
margins are liable to collect fluff and dirt. To remedy this defect we cover each
margin with a ribaud or strip of steel or flattened wire or of sheet metal which has
been perforated to correspond with the holes drilled in the bar and we secure the whole
together by means of rivets or suitable fasteners. This modification is illustrated by
Figs. 6 and 7 in which e e are the ribands which we apply to cover the margins of the
foundation. The rivets ff pass through the said ribands the card foundation and the
bar and secure all together. Each riband by preference extends in one piece from
end to end of the card. Although we have described the ribands as being made of
steel we do not confine ourselves to this metal.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed we declare that what we claim is :-
(1) The riband of metal slit so as to partially detach tongues which are bent down
at right angles to the flat face of the riband substantially as and for the purpose set
forth and indicated hereinbefore and by Figs. 1 to 5 of the accompanying drawings.
(2) As a means for fastening card clothing to flat bars a metal riband wide enough
to cover the margin of the card foundation slit so as to form tongues which extend in
the direction of the length of the riband before being bent and which when bent can
be passed through the perforations or slits in the flat bars and be clenched at the back
substantially as set forth and indicated.
(3) The application of metal ribands to cover the margins of the foundation when
securing card filets to flat bars substantially as set forth and indicated with reference
to Fig. 6 of the drawings.
