Improved Means for Securing the Wire Card Clothing to the
"Flats" of Carding Engines.
We FRED LAW of Cleckheaton in the County of York, Card Clothing
Manufacturer, and JOSEPH SEEL of 12 Nelson Street Lower Broughton Man-
chester in the County of Lancaster Mechanical Engineer, do hereby declare the
nature of this invention to be as follows:-
at
This invention relates to improved means for securing the wire card clothing to
the cast iron "flats" of carding engines the object of the invention being to
dispense with the necessity for drilling or notching the edges of the "flats
intervals; also with the use of rivets, pins, staples or other such like fastenings:
and to secure the clothing to the "flats" by means of longitudinal strips of metal
which effectually cover the edges of the card clothing but do not pass round the
edges or back of the "flat" whereby the width of the latter is not increased, and the.
chain of flats is not lengthened.
For the purposes of our invention we cut or otherwise form in the face of the cast
iron flat to which the card clothing is to be secured a continuous longitudinal saw-
cut or "kerf" near to each edge thereof, that is just outside the edges of the strip of
card clothing, and extending from end to end of the "flat."
These cuts or "kerfs" are not made in a direction perpendicular to the face of
the "flat" but at an angle of about forty five degrees (more or less) to the said face
extending downwards and inwards towards the centre.
We next provide strips of metal about one quarter of an inch in width (more or
less) serrated at one edge and plain at the other, and of suitable length equal to
that of the "flats."
These strips we bend over longitudinally in such a way that when their plain
edges are placed in the angular saw-cuts or "kerfs" above mentioned, and pressed
home their serrated edges will be brought down onto the edges of the card
clothing.
We then place the "flat" and clothing face upwards in a groove made for that
purpose in a metal block or anvil and by means of any suitable tool or apparatus
we apply downward pressure thereto so as to cause the serrated edges of the metal
strips to be pressed into or onto the face of the clothing and we then pass a plough
along the serrated edge, which causes the metal strips to be forced outwards from
each other so as to stretch the clothing in width.
This pressure also at the same time causes the plain edges of the strips to be
firmly clinched into the angular saw cuts or "kerfs" in the face of the cast iron
"flat" whereby the wire card clothing is securely united to the latter.
Instead of making the angular saw cuts or
"kerfs as above described, we some-
times form dovetail grooves in the face of the "flat" near the edges the plain edges
of the metal strips, being so bent as to fit therein.

Improved Means for Securing the Wire Card Clothing to the
"Flats" of Carding Engines.
We FRED LAW of Cleckheaton in the County of York, Card Clothing
Manufacturer, and JOSEPH SEEL of 12 Nelson Street Lower Broughton Man-
chester in the County of Lancaster, Mechanical Engineer, 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 improved means for securing the wire card clothing to
the cast iron "flats" of carding engines, the object of the invention being to
dispense with the necessity for drilling or notching the edges of the flats at
intervals, and to secure the clothing to the flats by means of longitudinal strips of
metal which effectually cover the edges of the card clothing, but do not pass round
the edges or back of the flat, whereby the width of the latter is not increased, and
..the chain of flats is not lengthened.
The nature of our said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the sheet of drawings hereunto annexed (which are made about twice the real size)
and the following explanation thereof.
For the purposes of our invention we cut or otherwise form in the cast iron
"flat" a (see transverse sectional view Fig. 1) to which the card clothing is to be
secured, a continuous longitudinal saw cut or "kerf" near to each edge thereof,
that is, just outside the edges of the strip of card clothing, and extending from end
to end of the "flat." These cuts or "kerfs" are not made in a direction
perpendicular to the face of the "flat," but at an angle of about forty five degrees
(more or less) to the said face extending downwards and inwards towards the centre
as shown.
We next provide strips of metal about one quarter of an inch in width (more or
less) serrated at one edge and plain at the other, and of suitable length equal to that
of the "flats."
These strips we bend over longitudinally (as shown at c on the perspective view
Fig. 2) in such a way that when their plain edges are placed in the angular saw
cuts or "kerts" above mentioned and pressed home their serrated edges will be
brought down onto the edges of the card clothing.
We then place the "flat" and clothing face upwards in a groove made for that
purpose in a metal block or anvil, and by means of any suitable tool or apparatus we
apply downward pressure thereto so as to flatten the top of the two metal strips c
and cause the serrated edges of the same to be pressed into or onto the face of the
clothing as shown at Fig. 3, and we then pass a plough along the serrated edge
which causes the metal strips c to be forced outwards from each other, so as to
stretch the clothing in width, and in order to give a better grip we groove the
surface of the "flat" longitudinally at or near the edges as shown at a Figs. 1
and 3. Sometimes we vary the positions of the "kerf" and the bend of the strip c
as shown at Fig. 4. or instead of making the angular saw cuts or "kerfs" b as above
described we sometimes form dovetail grooves d in the face of the "flat" near the
edges (as shown at Fig. 5) the plain edges of the metal strips c being so bent as to
fit therein as shown at Fig. 6. The form of the finished fastening is shown in section
at Fig. 7.
I
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 :-
"
The improved means for securing the wire card clothing to the cast iron "flats
of carding engines by cutting angular or dovetailed "kerfs or grooves in the face
"

page_text: of the flats near to each edge thereof, and pressing thereinto longitudinally bent
strips of metal plain at one edge and serrated at the other such metal strips not
passing round the edges or back of the "flats" but being bent and compressed
substantially in the manner hereinbefore described and illustrated by the drawings.
