PROVISIONAL SPECIFICATION.
Improvements in Machines for Folding and Measuring Fabrics.
We CAROLINE COOPER, JAMES COOPER, SQUIRE COOPER, and HENRY
COOPER trading fas C. Cooper & Sons Machinists of Thomas Street Works
Radcliffe in the County of Lancaster do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in machines for folding & measuring
fabrics. It has for its object the providing of simpler mechanism, whereby the
machine can be more rapidly & accurately adjusted from folding one length of plait
or lap to other lengths.
In place of moving the the top stud or pin of swivilling arm, separtely & by
hand, for more or less swivil of folding knives as at present, we move the bottom
swivilling arm stud or pin in a slot, by means of a lever or other equivalent, working
on a stud or centre, fixed to a bracket or framework of the machine. One end of
the said lever is connected with the said bottom swivilling arm stud, and the other
end of the lever is connected with the radial arms at present in use, so that when
the said radial arms are adjusted, to compensate for the various lengths of plaits or
laps of the fabric, it accurately adjusts the swivilling of the folding knives at the
same time.

Improvements in Machines for Folding and Measuring Fabrics.
CAROLINE COOPER, JAMES COOPER, SQUIRE COOPER, and HENRY COOPER,
all of The Thomas Street Works, Radcliffe, in the County of Lancaster, Engineers,
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 machines for folding and measuring textile fabrics, and
its object is to simplify the construction and arrangement of that part of the
apparatus by means of which the swivelling or alterations in the angular position of
the folding kuives is effected.
The type or class of machines to which our improvements relate is described and
illustrated in and by the Specification of Letters Patent granted to Joseph Cooper
No. 17874 dated the 9th day of November 1889.

page_text: In carrying our present invention into effect we provide each end of the
swivelling bar with a stud, that at the upper end engaging with a slot or hole in
the knife frame, and that at the lower end with a slotted bracket. This latter
stud is embraced by the lower end of a lever of which the upper end engages with
one of the radial arms carrying the holding down rails. This lever is fulcrumed
to the frame side of the machine so that when the radial arms are caused to
approach to or recede from each other, the lever has its position altered and thus
effects the movement of the swivelling bar.
Our improvements are illustrated by the accompanying drawings which are
hereinafter referred to and in which:
Figure 1 is a side elevation, and
:-
Figure 2 an end view of the lower end of the swivelling bar and its accessories
for adjustment.
A is one of the folding arms which carry the knife frame B, and is pivoted at C
in the usual manner. The radial arms D'D' which are constructed as at present,
are also pivoted at C, but one of them, D, is slotted at E for the reception of a
stud F secured to the upper end of a lever G, fulcrumed at H to the frame side
of the machine. The other and lower end of the lever is slotted or forked as
shewn at I, and engages a stud J, secured in the lower end of the swivelling bar K
which is arranged in the same plane preferably as A. The upper end of the
swivelling bar K is connected with the knife frame B either at a fixed point or by
a stud to a slot L formed in an extension from the knife frame. The stud J at the
lower end of the swivelling bar K, enters a slot M in the fixed bracket N, and may
he secured therein by a back nut or otherwise.
The device for causing the radial arms D D' to approach to or recede from each
other when a longer or shorter fold is required, consists of the right and left handed
screw Opassing through and engaging with corresponding nuts P P which carry
studs working in slots in the arms.
The operation of effecting an alteration in the length of the fold is effected in
the following manner :-The stud nuts at the upper and lower ends of the
swivelling bar having been loosened, the distance apart of the arms D D¹ is
adjusted by the rotation of the screw O whereby the lever G is moved upon its
fulcrum through its connection with D by the stud F. This movement shifts the
position of the stud J in the slot M, and thus alters the angular position of the
kuife frame. This having been effected, the nuts are again tightened and
the machine is again ready for work.
The holding down rails R R' the levers S S' the bowls T and the connecting
rod U by means of which the machine is driven, and the other parts of the machine
are constructed arranged and operated substantially as in the existing machines.
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 we are
aware of the Specification of the expired Letters Patent No. 1142 of 1872 and
we claim nothing that is described in that Specification but what we claim is :-
In machines for folding and measuring fabrics a device for altering and adjusting
the angular position of the folding knives, consisting essentially of a swing lever G
engaging at its upper end with the radial arm D and having its lower end capable
of being adjustably secured in a slot M by means of a stud on which the lower end
of the swivelling bar is pivoted, constructed and arranged substantially as herein-
before described and as illustrated by the accompanying drawings.
