Improvements in or relating to Carding Engines.
I, WILLIAM SCOTT TAGGART, of 285, Chorley Old Road, Smithells, near Bolton,
in the County of Lancaster, Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to revolving or travelling flat carding engines and is
designed to simplify the construction of the flats and flexibles employed.
In carrying my invention into effect I prepare the ends of the flats in such
manner that the working or carding surfaces are parallel to the surface of the
flat wire and in order to obtain the necessary bevel or heel of the flats during
the operation of carding I employ flexibles cast or formed with two surfaces at
parallel heights one surface being raised above the other a sufficient height to
give the necessary heel or bevel to the flats or the surfaces may vary in height
from each other so that the inclination of the bevel of the flats may be varied as
they pass over the flexibles. The difference in the height between the two surfaces
of the flexibles may be obtained by making them in two parts and fixing them
together in any convenient manner.
It wish it to be understood that the gist of my invention is to provide a flexible
having two surfaces for the purpose of giving the necessary bevel or heel to
flats during the operation of carding.
Improvements in or relating to Carding Engines.
I, WILLIAM SCOTT TAGGART, of 285, Chorley Old Road, Smithells, near Bolton,
in the County of Lancaster, Consulting and Mechanical Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to revolving or travelling flat carding engines and is
designed to simplify the construction of the flats and flexibles employed.
In carrying my invention into effect I prepare the ends of the flats in such a
manner that the working or carding surfaces are parallel to the surface of the
flat wire and in order to obtain the necessary bevel or heel of the flats during
the operation of carding I employ flexibles cast or formed with two surfaces at
parallel heights one surface being raised above the other a sufficient height to
give the necessary heel or bevel to the flats or the surfaces may vary in height

page_text: from each other so that the inclination of the bevel of the flats may be varied as
they pass over the flexibles. The difference in the height between the two surfaces
of the flexible may be obtained by making them in two parts and fixing them
together in any convenient manner.
I wish it to be understood that the gist of my invention is to provide a flexible
having two surfaces for the purpose of giving the necessary bevel or heel to
flats during the operation of carding.
In the accompanying sheet of drawings-
Figure 1 is a transverse vertical section through the flexible, the engine bend,
and part of the main cylinder and chain of travelling flats of a carding engine.
Figure 2 is an end view looking from the outside of the carding engine.
Figure 3 is a plan view of one end of a flat showing the specially prepared
working surface.
Figures 4, 5 and 6 are similar views to Figs. 1, 2, 3 respectively of an alterna-
tive arrangement in which the flexible has its higher surface on the outside
instead of on the inside as in the first arrangement.
Similar letters and figures refer to similar parts throughout the several views.
In the drawings,-- designates the main cylinder, one of the flats, c the engine
bend or side framing and d the flexible bend which according to my improvements is
made in one part having two concentric surfaces 1-2 and 2-3 in different
planes each parallel with the surface of the wire on the main cylinder. At each
end of each flat 6 the surfaces 4, 5 and 6 are made parallel to the surface of the
card wire on the flat, all the surfaces 4, 5 and 6 being in the same plane, while
the surface is recessed out a little deeper than the amount of heel and toe
inclination it is intended that the flat shall have when working over the main
cylinder.
The surface G on the flat bears on the surface 1-2 on the flexible but the
surface being recessed clears the higher surface 2-3, so that it passes over
the flexible without touching it, the surface 4 on the flat bears on the higher
surface 2-3 on the flexible and the surface 5 being in the same plane as the
surface 4 clears the lower surface 1-2 on the flexible.
In Figures 1, 2 and 3 the flexibles d have their higher surfaces 2-3 on the
inside and the flat ends have their corresponding recesses 7 on the inside; but
in Figures 4, 5 and 6 the higher surfaces 3-2 are on the outside and the corre-
sponding recesses 7 on the flat ends are also on the outside.
Instead of making each flexible d in one piece as shown I may make it in
two parts bolted or otherwise rigidly secured together with two surfaces at
different heights as described, and these surfaces, instead of being parallel and
concentric, may vary in height if desired.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The combination with a flat having its ends prepared with the surfaces 4, 5,
6 and 7, of flexibles each prepared with two preferably concentric surfaces 1-2
and 2-3 in different planes substantially as and for the purposes herein set
forth.
