PROVISIONAL SPECIFICATION.
Improvements in Clipping Appliances for Taking Creases and Folds
Out of the Edges and Stretching Woven Fabrics during various
Finishing Operations.
1, Sir JAMES FARMER, of Adelphi Street Iron Works, Salford, in the County of
Lancaster, Knight, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in clipping appliances for taking creases
and folds out of the edges and stretching woven fabrics during various finishing
operations.
In constructing a clipping appliance according to my invention I fix a pair of
revolving discs or circular plates on a loose sleeve fitted on a stationary spindle.
These discs support any suitable number, say for example eight pairs of pivoted elbow
levers, the long arms of which are preferably reduced to a knife edge to grip the edges
of the fabric and the short arms pass through slots in the discs and by means of
springs are kept continually pressing the long arms of each pair towards one another.
Above and below each disc is fixed a hollow stationary cam or equivalent which
acts upon bowls or rollers fitted upon the short arms of the elbow levers so as to open
and close the long arms as the discs revolve.
I employ one of my improved clipping appliances on each side of the machine into
which the fabric is to be guided and I guide the fabric so that its edges pass between
the pairs of revolving dises and are gripped successively by the pairs of elbow lovers,
as they are closed by the springs after having been opened by the stationary cams.
In this way the action of each pair of elbow levers mounted in the revolving discs
is equivalent to that of a closed finger and thumb being drawn away from the fabric
to take out folds and creases from the edges and at the same time to stretch the cloth.
The clipping appliances are mounted adjustably so that their distance apart can be
regulated to compensate for varying widths of cloth.

Improvements in Clipping Appliances for Taking Creases and Folds
Out of the Edges and Stretching Woven Fabrics during various
Finishing Operations.
I, Sir JAMES FARMER, of Adelphi Street Iron Works, Salford, in the County of
Lancaster, Knight, 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 :-
My invention relates to improvements in clipping appliances for taking creases
and folds out of the edges and stretching woven fabrics during various finishing
operations.
In constructing a clipping appliance according to my invention I fix a pair of
revolving discs or circular plate on a loose sleeve fitted on a stationary spindle.
These discs support any suitable number, say for example eight pairs of pivoted elbow
levers, the long arms of which are preferably reduced to a knife edge to grip the
edges of the fabric and the short arms pass through slots in the discs and by means of
springs are kept continually pressing the long arms of each pair towards one another.
Above and below each disc is fixed a hollow stationary cam or equivalent which acts

page_text: upon bowls or rollers fitted upon the short arms of the elbow levers so as to open and
close the long arms as the discs revolve.
I employ one of my improved clipping appliances on each side of the machine into
which the fabric is to be guided and I guide the fabric so that its edges pass between
the pairs of revolving discs and are gripped successively by the pairs of elbow levers,
as they are closed by the springs after having been opened by the stationary cams.
In this way the action of each pair of elbow levers mounted in the revolving discs
is equivalent to that of a closed finger and thumb being drawn away from the fabric
to take out folds and creases from the edges and at the same time to stretch the cloth.
The clipping appliances are mounted adjustably so that their distance apart can
be regulated to compensate for varying widths of cloth.
Fig. 1 represents a vertical section of my improved clipping appliance.
Fig. 2 is a plan of the lower revolving disc and clipping levers.
a is the upper revolving disc and the lower revolving disc both fixed on the
sleeve c which turns on the stationary spindle d; e e are the long arms of the upper
clipping levers carried by the disc a which are fulcrumed at e¹ el; the short arms e
of these levers are provided with antifriction bowls ee³ and with studs et e on which
are studs and springs which studs and springs enter recesses in the boss of the disc a;
these springs exert pressure on the short arms of the levers and press them outward
when they are not lield back by the cam fand cause the ends of the long arms e e of
the levers to move downward and with the corresponding levers below them clip the
fabric under operation; a¹ is a plate which is screwed on to the lower side of the
fabric a to keep the levers in position; f is a stationary cam fixed at the top of the dead
spindle d; part of the internal diameter of this cain is large enough to allow the
arms e²e to be moved outward and part of the diameter is small enough to force the
armis e e inward and release the fabric held by the long arms of the levers; ii are
the long arms of the lower clipping levers carried by the disc b and fulcrumed at ¹zl
and having short arms provided with antifriction bowls ³ ³ and studs ii on
which are springs which enter recesses in the boss of the disc b, the levers being
actuated by the springs and by the cam j in a similar manner to the upper gripping
lever o ;
is a plate which is secured on to the upper side of the disc b to keep the
levers in position; k is a bevel wheel fixed on the sleeve c and motion is transmitted
to it through the bevel wheel fixed on the shaft m which latter extends below and
across the path of the fabric to drive simultaneously another similar pair of discs with
clipping levers which hold the other edge of the cloth; n is a screw having a right
hand thread at one end and a left hand thread at the other to traverse the clipping
appliances at either side of the cloth nearer to or farther from each other to suit
different widths of cloth. Each sliding bracket has a nut n¹ which fits a thread of
the screw n.
The cams and j are adjustable to admit of the clipping levers being opened or
closed at any point that may be desired to clip or release the fabric.
By the use of my improved apparatus creases and folds may be quickly and
effectively taken out of woven fabrics and the fabric can be stretched to the desired
extent without perforating or injuring the edges of the fabric.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The combination and arrangement of parts forming the improved appliance for
taking creases and folds out of and for stretching woven fabrics substantially as herein
described and shown.
2. The combination with a revolving disc or discs of a stationary cam or cams for
operating clipping appliances for opening and stretching woven fabrics.
