PROVISIONAL SPECIFICATION.
Improvements in Means for Securing Card Clothing to Carding
Engine Flats.
I, EDUARD HERKNER, of the Firm of A. Herkner's Söhne, Reichenberg,
Bohemia, in the Empire of Austria, Manufacturer, do hereby declare the nature of
this invention to be as follows:-
My invention relates to the fastening of card clothing to carding engine flats, the
chief advantages being that the simplicity of the fastening renders it absolutely
reliable, and that the fastening takes up less room on the iron flats than hitherto, so
that the flats can be so made as to work very close to the margin, thus allowing an
increased working space.
According to this invention the card-fillets are fixed on the flats by means of
metal bars, on one edge of which more or less pointed or blunt teeth or tongues are
formed by corresponding notches, and these are inserted, bent at a right angle,
through the edge of the card-fillet, and the holes which lie underneath it, and have
their ends, which project, turned down over the holes. So that the card-fillets may
be closely applied to the flats at all points, the former are stretched whilst being
fastened in position.
For the purpose of increasing the rigidity of the bars they may be strengthened
at the points which are not notched.
Since the card-clothing may be made so as to act over its whole surface at both
edges with the exception of a very narrow margin, or even right up to the edge
close to the holes for securing it, much working space is gained."

COMPLETE SPECIFICATION.
Improvements in Means for Securing Card Clothing to Carding
Engine Flats.
I, EDUARD HERKNER, of the Firm of A. Herkner's Söhne, Reichenberg,
Bohemia, in the Empire of Austria, Manufacturer, 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 relates to the fastening of card clothing to carding engine flats, the
chief advantages being that the simplicity of the fastening renders it absolutely
reliable, and that the fastening takes up less room on the iron flats than hitherto,
so that the flats can be so made as to work very close to the margin, thus allowing
an increased working space.
According to this invention the card-fillets are fixed on the flats by means of
metal bars, on one edge of which more or less pointed or blunt teeth or tongues are
formed by corresponding notches, and these are inserted, bent at a right angle,
through the edge of the card-fillet, and the holes which lie underneath it, and have
DQ17

page_text: their ends, which project, turned down over the holes. So that the card-fillets may
be closely applied to the flats at all points, the former are stretched whilst being
fastened in position.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing, in which :-
Figure 1 is a plan of part of a carding engine flat having card clothing secured
thereto according to my invention;
Figure 2 is a section along the line x-x of Figure 1:
Figure 3 is a plan of the underside of the flat:
Figures 4, 5, and 6 are perspective views illustrating various ways of shaping the
bars to fix the card-fillets in their places.
As herein before stated, the card-fillets a are fixed to the flats b by means of
bars C, which have oblique rectangular or other notches (Figures 4, 5, 6) cut therein
so as to form more or less acute or blunt projections c¹ which are turned over so as
to lie at right angles to the plane of the bars.
These projections are inserted through the edge of the card-fillet or clothing a,
and through the correspondingly arranged holes in the flat b, and their ends
which project through the holes are then turned over as shewn in Figure 3.
The above described method of fastening is carried out under suitable conditions
of tension of the carding combs, so that the latter lie closely on the cards at all
points.
For the purpose of increasing the rigidity of the bars c they may be strengthened
at the points which are not notched.
Since the card-clothing a may be made so as to act over its whole surface at
both edges with the exception of a very narrow margin, or even right up to the
edge close to the holes for securing it, much working space is gained.
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 :-
The employment for securing card clothing to carding engine flats of metal
bars c in which more or less acute or blunt projections c are formed by oblique,
rectangular, or other notches or indentations, the projections being turned up at
right angles to the plane of the bars and passed through the edges of the card-
fillets and their ends which project from the holes in the flats turned down,
substantially as hereinbefore described.
