PROVISIONAL SPECIFICATION.
Improvements in the Flats or Bars of Flat Carding Engines, and in
Appliances for Securing Card Clothing thereon and thereto.
I, RICHARD WILKINSON BATEMAN of 5 Hanover Street, Halifax in the
County of York, Shoemaker, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in the flats or bars of flat carding
engines and to improvements in the method of and means employed for stretching
and securing card clothing to such flats or bars.
According to this invention I construct a flat preferably of rolled sheet steel the
upper and outer edges of the bar having shaped recesses formed thereon
extending the whole length of the bar or flat. The foundation of the card clothing
is cut to the required width and each edge of the foundation is then pressed onto
a row of short pins which are set in strips of metal the length of the flat or bar.
When a strip of metal is attached to each edge of foundation by means of the
pins, the edges of the card clothing and the metal strips and pins are slided
longitudinally along the flat or bar so that the metal strips and edges of the
foundation are in the recesses along the outer edges of the flat.
In order to stretch the foundation evenly on the face of the flat or bar a strip
of metal with angular edges is now forced between to the two outer strips the edges
of which are slightly recessed to receive the angular edges of the stretching strip,
so that the outer strips are forced apart and into the recesses and the foundation is
stretched and securely fastened to the flat or bar.
Instead of the three strips of metal above described, the two outer strips may
be so wide as to meet one another and their inner edges connected by a joint or
hinge so that when the outer edges are forced under the recesses, and the joint or
hinge straightened the foundation will be stretched and secured to the flat.
A suitable apparatus for sliding the stretching or centre strip between the outer
strips consists of a guide or slide which is placed close to the end of the flat or bar
and the centre strip is forced through this guide by means of a finger or carriage
mounted on a screwed shaft and operated by hand or power.
The stretching strip may be either a flat strip or a round rod of metal.

COMPLETE SPECIFICATION.
Improvements in the Flats or Bars of Flat Carding Engines, and in
Appliances for Securing Card Clothing thereon and thereto.
I, RICHARD WILKINSON BATEMAN of 5 Hanover Street, Halifax, in the
County of York, Shoemaker, 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 improvements in the flats or bars of flat carding
engines, and to improvements in the method of and means employed for stretching
and securing card clothing to such flats or bars.

page_text: Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the accompanying drawings, in
which
Fig. 1 is an end elevation partly in section of one end and part of the length of
a flat, together with the appliances for stretching the foundation fillet and securing
it to the flat.
Fig. 2 is a side elevation of Fig. 1.
The remaining figures are details or separate views of the several parts.
According to this invention, construct a flat 1 preferably of rolled sheet
steel, the upper and outer edges of the bar having shaped recesses formed
thereon extending the whole length of the bar or flat 1. The bar or flat 1 may be
formed in one piece as shewn at 1, or of two strips 1 secured by rivets 2 at
intervals of the length of the bar. The ends of the bar 1 are received in the slit 3
of the piece 4, which is, as shewn, of the usual form, but cast or formed separately
from 1. The rivets 5. 5 secure the parts 1 and 4 together, the outer end of the
part being angled or bevelled as shewn by dotted lines 6, so as to lie on a
corresponding incline 7 formed in part 4, so as to constitute a splice and give
increased security of the connection between 1 and 4.
The foundation 14 of the card clothing, is cut to the required width, and each
edge of the foundation is then pressed onto a row of short pius 9. 9 which are set
in strips or plates of metal 8. 8 the length of the flat or bar. The pins 9.9 are
drifted into the plates 8. S with their points standing outwards and in opposite
directions as shewn. When strip of metal 8 is attached to each edge of
foundation 14 by means of the pins 9. 9, the edges of the card clothing and the metal
strips 8.8 and pins 9. 9 are slided longitudinally along the flat or bar 1, so that the
metal strips 8. 8 and edges of the foundation 14 are in the recesses 10. 10 along
the outer edges of the flat 1.
In order to stretch the foundation 14 evenly on the face of the flat or bar 1, a
strip of metal 11 with angular edges is now forced between the two outer strips S. 8,
the edges of which are slightly recessed to receive the angular edges of the
stretching strips 11, so that the outer strips 8. 8 are forced apart and into the
recesses 10. 10, and the foundation 14 is stretched, and securely fastened to
the flat or bars 1.
At 12 is shewn a single plate having pins 9 in opposite directions, one edge of
the foundation 14 being placed on one line of pins, and on being pulled tightly across
the plate and lowered onto the opposite line of pins, the latter holds the foundation 14
tightly stretched, and the margin of the foundation will be cut off along the edges
of the plate 12, and the latter and the card fillet then will be placed in the
recesses 10. 10 of part 1 as already described in reference to Figs. 1 and 2.
At 13 is an angular cross piece, which when screwed to the end of the bar,
serves to cover the end of the foundation as ordinary.
Instead of the three strips of metal S. 8 and 11 above described, the two outer
strips 8. 8 may be so wide as to meet one another as shewn at 16, and their inner
edges connected by a joint or hinge 16, so that when the outer edges are forced
under the recesses 10. 10, and the joint or hinge 16 straightened, the foundation 14
will be stretched and secured to the flat 1.
A suitable apparatus for sliding the stretching or centre strip 11 between the
outer strips 8. 8, consists of a guide or slide placed close to the end of the flat or
bar 1, and the centre strip 11 is then forced through this guide by means of a
finger or carriage mounted on a screwed shaft and operated by hand or power.
Having now particularly described and ascertained the nature of my snid inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
(1) The improved flat or bar constructed as illustrated by Fige. 1 and 2 and
herein fully described.

page_text: (2) A flat or bar constructed of parts 1. 1 or made of one piece 1* for receipt
of a card foundation, together with the holding and stretching device as hercin
fully described.
