Improvements in Travelling Flat Carding Engines.
I, ROBERT TAYLOR, JUNIOR, of Asa Lees and Company Limited, of Soho Iron
Works, Oldham, in the County of Lancaster, Engineer, do hereby declare the
nature of this invention to be as follows:-
My invention relates to improvements in travelling flat carding engines and
consists in certain novel constructions and combinations of parts to enable any
flat to be disconnected from the travelling chains without disturbing or displacing
the latter.
In one such construction I form a special chain composed of either long or
short links united by being pivoted at each end, to a shank or distance piece
forming part of a tube, one half of which is cut away for the greater part of its
length while from the remainder of its length only about one-third is cut away
A stud is screwed horizontally into each end of each flat and this stud is of two
diameters, one part, the larger, fits into the half tube on the chain, the other
part is reduced in diameter to allow the two projections formed by only cutting
away one-third of the tube to pass over when the stud is partly unscrewed
from the end of the flat, and then by tightening up the screwed stud the larger
diameter is locked within the two projections and the flat cannot be detached
from the chain without again screwing back the stud.
As an alternative to the foregoing construction a stud with two flattened sides
might be employed to lock and release the tubular part which in this case need
only have about one-third cut away throughout its whole length.
As a further alternative construction the links of the chain may be pivoted
together by internally threaded bushes and the flats connected and disconnected
by means of studs screwed where they pass through the threaded bushes and
preferably plain and reduced in diameter where they enter the ends of the flats.
The bushes are kept from turning round by means of fins or projections thereon
engaging recesses formed to receive them in the links or by any other suitable
device.

page_text: 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 improvements in travelling flat carding engines and
consists in certain novel constructions and combinations of parts to enable any
flat to be disconnected from the travelling chains without disturbing or displacing
the latter.
In the accompanying sheet of drawings-
Figures 1 and 2 are elevations and Figure 3 is a plan, all partly sectional, of
one of the chains and some of the flats of a travelling flat carding engine to
which my present improvements are applied.
Figures 4 and 5 are a side elevation and plan, partly sectional, of an alter-
native construction.
Figures 6 and 7 are similar views to Figs. 4 and 5 of another alternative
construction.
Similar numerals refer to similar parts throughout the several views, in
which―
1 denotes the links of the travelling chain, 2 the pins which pivot the links
together, and 3 the travelling flats.
In the construction illustrated by Figs. 1, 2 and 3 I pivot on each pin 2 a
shank 4 forming part of a tube, one half of which is cut away for the greater
part of its length while for the remainder of its length, only about one third
is cut away so as to leave two projecting portions 5, one on either side of the
tube. A stud 6 is screwed horizontally into each end of each flat, and this
stud 6 is of two diameters as clearly shown in Fig. 3; one part, the larger, fits
into the half tube on the chain, the other part is reduced in diameter to allow
the two projections 5 on the half tube to pass over and so disconnect the flat
when the stud 6 is partly unscrewed from the end of the flat, and then by
tightening up the screwed stud its larger diameter is locked within the two
projections 5, and the flat cannot then be detached from the chain without again
screwing back the stud 6.
Figs. 4 and 5 show substantially the same construction as Figs. 1 to 3, but
in this case, instead of the half tube being formed on a shank it is formed
with a distance piece 7 to which the links 1 are pivoted by pins 2.
As an alternative to the foregoing constructions, a stud with two flattened
sides as described in the Specification to my previous Patent No. 14750 of 1898,
might be employed to lock and release the tubular part carried by the shank 4
or distance piece 7 and in this case the tubular part need only have about one
third cut away throughout its whole length.
As a further alternative construction, which is illustrated by Figs. 6 and 7,
the links 1 of the chain may be pivoted together by internally threaded
bushes 8 and the flats 3 be connected and disconnected by means of studs 9
screwed, where they pass through the threaded bushes 8, and preferably plain
and reduced in diameter where they enter the ends of the flats.
The bushes 8 are kept from turning round by means of a fin or projection 10
on each link engaging a flat place on the bush or by any other suitable device.
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:
1. The combination with the travelling chains, having shanks 4 pivoted on
the link pins 2, and formed with semi-tubular parts having projections 5, of
the screwed studs 6 each of two diameters, substantially as and for the purposes
herein described with reference to Figs. 1, 2 and 3.
2. The combination with the travelling chains having distance pieces 7 carry-
ing semi-tubular parts each having two projections 5, of the screwed studs 6

page_text: each of two diameters substantially as and for the purposes herein described
with reference to Figs. 4 and 5.
3. The combination with the links 1 of the internally threaded bushes 8 and
the screwed studs 9 substantially as and for the purposes herein described with
reference to Figs. 6 and 7.
