Improvements in the Manufacture of Twist Lace.
We, ROBERT FREDERICK CAREY, Managing Director of the Firm of Carey & Sons,
Limited, Lace Manufacturers, and WILLIAM ROBINSON SMART HANCOCK, Lace
Designer, both of Heathcote Street, Nottingham, do hereby declare the nature of
this invention to be as follows:-
The object of this invention is to produce scalloped edges without the use of
an end jacquard.
Formerly curtains, window blinds, and similar goods, had to be taped at consider-
able expense to give the requisite scalloped edge.
By means of this invention we attain the same effect on the machine.
We introduce down the extreme edge of the fabric, by means of a bar shogged
in the usual way, a thick thread more heavily weighted than the other spool threads.
The spool threads, usually three or more, next the thick thread, are, when the
latter is shogged inwards, gathered together by it along with the bobbins and warps,
the curvature of the scallop being determined by the course of the thick thread,
and this is governed by droppers worked by needles from the upright jacquard.
A carriage is omitted between each pair of adjacent breadths of fabric on the
machine, but the spool thread of that pillar is retained and forms a draw thread
connecting the two breadths together. At the points of the scallops this thread
is jacked, so as to traverse three gaits and connect the points together, but at
the concavities of the scallops it hangs down loose.

A carriage is omitted between each pair of adjacent breadths of fabric on the

necting the two breadths together. At the points of the scallops this thread is
jacked, so as to traverse three gaits and connect the points together, but at the
concavities of the scallops it hangs down loose.
The drawing is a diagram to a greatly enlarged scale of the edges of two curtains
or pieces of lace, six pillars of each being shown.
a are the ordinary spool threads, a¹ the thick heavily weighted spool threads at
the edges of the pieces, a² the spool thread between the pieces, 6 the bobbin threads
and c the warps.
The pillars are connected in the ordinary way by clothing forming the pattern.
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. Forming scallops at the edges of lace by means of a heavily weighted spool
thread which is shogged inwards and gathers together the threads of the adjacent
pillars substantially as described.
2. The manufacture of twist lace substantially as described and illustrated in the
drawing.
