Improvements in Appliances for Securing Card Clothing to the
Bars or Flats of Flat Carding Engines.
I ALFRED HITCHON of Globe Works, Accrington, in the County of Lancaster,
Machine Salesman do hereby declare the nature of this invention to be as
follows:-
This invention relates to means and appliances for securing card clothing to the
bars, or flats of carding engines. The object of this invention is to ensure effective
fastening of the foundation fabric to the bars by means of compound clamps applied
to each edge of the foundation fabric, and bar.
According to this my said invention I first encase, and enclose each marginal
edge of the foundation fabric in a metallic border, or clamp forming a metallic
beading along the length of the foundation. One edge of the beading may be
serrated, the serrations, or spaces between the teeth serve to prevent the foundation
fabric being cut by the edges of the beading being nipped into the foundation
fabric.
The metallic beaded foundation fillet is now to be put on the bar, and each of its
metallic headed edges is to be secured thereto by a second metallic trough, or clamp,
one edge of which lies upon and over the metallic beading so as to enclose and
cover the latter, the other edge is turned around the outside edge of the bar, or
into a longitudinal groove, or recess formed in the same.
The outer trough, or clamp may have its edge serrated, and may only enclose
the metallic beading, or the said serrations may enclose the beading, and also enter
the foundation fabric giving additional hold, the serrations being preferably of
different pitch to those of the metallic beading so that the teeth of the serrations of
the outer trough, or clamp are "in and out" with the serrations of the metallic
beadings so that both sets of serrations are not in the same threads of the foundation
fabric and thereby less liability of cutting the foundation.

Improvements in Appliances for Securing Card Olothing to the
Bars or Flats of Flat Carding Engines.
I, ALFRED HITCHON, of Globe Works, Accrington, in the County of Lancaster,
Machine Salesman 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 means and appliances for securing card clothing to the
bars, or flats of carding engines. The object of this invention is to ensure effective
fastening of the foundation fabric to the bars by means of compound clamps applied
to each edge of the foundation fabric, and bar.
According to this my said iuvention I first encase, & enclose each marginal
edge of the foundation fabric in a metallic border, or clamp forming a metallic
beading along the length of the foundation. One edge of the beading may be
serrated, the serrations, or spaces between the teeth serve to prevent the foundation
fabric being cut by the edges of the beading being nipped into the foundation
fabric.

page_text: The metallic beaded foundation fillet is now to.be put on the bar, and each of its
metallic beaded edges is to be secured thereto by a second metallic trough, or clamp,
one edge of which lies upon and over the metallic beading so as to enclose and cover
the latter, the other edge is turned around the outside edge of the bar, or into a
longitudinal groove, or recess formed in the same.
The outer trough, or clamp may have its edge serrated, and may only enclose the
metallic beading, or the said serrations may enclose the beading, and also enter the
foundation fabric giving additional hold, the serrations being preferably of different
pitch to those of the metallic beading so that the teeth of the serrations of the outer
trough, or clamp are "in and out" with the serrations of the metallic beadings so
that both sets of serrations are not in the same threads of the foundation fabric
and thereby less liability of cutting the foundation.
Such being the nature and object of this my said invention the following
is a complete description thereof, reference being had to the accompanying
drawings
- Figure 1, shows a section and oblique view of a piece of the outer clamp with
serrations or spaces cut out to form teeth as shewn with their points bent upwards
for encasing the margin edge of the fabric foundation, metallic border and flat
edges, as further described :-
Fig. 2 is a similar view of a piece of metallic border with one serrated edge, the
spaces and teeth being of finer pitch than the outer clamp.
Fig. 3 is an example of Fig. 2, but with extra bend like Fig. 1.
Fig. 4 is another shape of metallic border without teeth or serrations for same
like purpose as Figs. 2 and 3.
Fig. 5 is an end section of card foundation D with the two outside clamps A A
pressed in position also the two pieces of metallic border CC of same section as
shewn separately Fig. 4.
Fig. 6 shews all the parts of Fig. 5 fixed to flat E by bending the outer clamps A A
over its edges.
Fig. 7 is same as Fig. 6, but with pieces of metallic bead BB (like section to
Fig. 2) which are held within the two outer clamps AA when the outer clamps are
fixed to flat E.
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 metallic border or beading combined with a metallic clamp, as illustrated on
annexed sheet of drawings for purposes set forth.
