Improvements in Heald Knitting Machinery.
We, THOMAS FIELDEN, Traveller, WILLIAM ASTLEY, and ROGER ASTLEY,
Heald and Reed Manufacturers, all of Higson Street, Blackburn, in the County
of Lancaster, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in machines employed in the manufacture
or knitting of fancy healds, the object being to render such machinery self acting
when it is desired to vary the knitting, which is accomplished by varying the
speed of the "take up" motion, so producing various counts, either finer or
coarser as desired, and on the same shaft without change of wheels or any other
part, ie, in a given space there may be more or less number of henids as desired.
The invention consists in controlling the "take up motion, consequently the
counts of the healds, by means of an extra row of pegs on the pattern lags, and
by simple appliances connected therewith.
"
According to this invention we employ a pattern cylinder as ordinary, but the
pattern chain has two rows of pegs, the additional row acting on a lever working
on a fulcrum stud, and the other end of this lever is jointed to a lever on a shaft,
on the end of which is a fork or clutch, which operates a cam or key, which locks
or grips the bose of a carrier wheel driving the ordinary change wheel of the
"take up" motion. When one of the additional pegs acts on the lever above.
mentioned, a partial turn is given the shaft, and the forked clutch draws the
carrier wheel out of gear with the change wheel,.so that for the time being; the
"take up" motion is stopped, consequently as the knitting proceeds, the counts
are finer, but when the "take up" motion is in operation, the healds are taken up
as knitted and are consequently coarser.
By arranging the additional row of pegs, the number of healds in a given space
can be regulated so that we are able to knit two, three, or four healds to oue dent
of the reed without any change of wheels.

COMPLETE SPECIFICATION.
Improvements in Heald Knitting Machinery.
We, THOMAS FIELDEN, Traveller, WILLIAM ASTLEY, and ROGER ASTLEY,
Heald and Reed Manufacturers, all of Higson Street, Blackburn, in the County
of Lancaster, 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 machines employed in the manufacture
or knitting of fancy healds, the object being to render such machinery self acting
when it is desired to vary the knitting which is accomplished by varying the
speed of the "take up” motion, ao producing various counts, either finer or coarser

page_text: as desired, and on the same shaft without change, of wheels or any other part,
i.e. in a given space there may be more or less number of healds as desired.
The invention consists in controlling the "take up" motion, consequently the
counts of the healds, by means of an extra row of pegs on the pattern lags, and
by simple appliances connected therewith.
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the annexed drawings, in
which:-
Fig. 1.is a side elevation of the improved apparatus for purpose aforesaid.
Fig. 2 is an end elevation of Fig. i.
According to this invention, we employ a pattern cylinder 1 as ordinary, but
the pattern chain 2 has two rows of pegs 3-4, the additional row 4 acting on a
lever 5 working on a fulcrum stud 6, and the other end of this lever 5 is by
link 8 jointed to a lever 7 on a shaft 9, on the end of which is a fork or clutch 10,
which operates a locking device or key 11, which locks or grips the boss or other
part of a carrier wheel 12 driving the ordinary change wheel 13 of the "tako up'
motion.
دو
The locking device consists of a boss or collar 11 loose on the short shaft 15,
but caused to rotate therewith by means of the key 15, and on the face of the
collar or boss 14 is a half clutch 16, the corresponding half clutch 17 being on
the carrier wheel 12, so that when these two are brought into contact by sliding
the boss or collar 11 on the shaft 15, as herein before described, the carrier
wheel 12 is locked on and caused to rotate with the shaft 15.
When one of the additional pegs 4 acts on the lever 5 above mentioned, a
partial turn is given the shaft 9, and the forked clutch or key 11 draws the carrier
wheel 12 out of gear with the change wheel 13, so that for the time being, the
"take up" motion is.stopped, consequently as the knitting proceeds, the counts are
finer, but when the "take up" motion is in operation, the healds are taken up as,
knitted, and are consequently coarser.
By arranging the additional row of pegs, the number of healds in a given space
can be regulated so that we are able to knit two, three, or four healds to one dent
of the reed without any change of wheels.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
(1) The general construction, arrangement, and combination of parts constituting
the said invention, as and for the purpose herein described; and substantially as
illustrated by the annexed drawings.
(2) The pattern cylinder 1, levers 5 and 7, fork 10, locking device or clutch 11,
and carrier wheel 12, all in combination, as and for the purpose herein described,
and substantially as illustrated by the annexed drawings.
