PROVISIONAL SPECIFICATION.
Improvements in Stentering Clips for Stretching Textile Fabrics.
I, EDMUND NUTTALL, of Wyndham Street, Bury, in the County of Lancaster,
Mechanical Draughtsman do hereby declare the nature of this invention to be as
follows:
This invention relates to the gravity clips employed in stentering machines for
gripping or engaging the selvages of the cloth and is designed to reduce the weight
of the finger resting upon the cloth to hold the gripper open.
It consists essentially in constructing the clip with a link or links projecting
behind the gripper pivoted or connected at one end to the gripper and at the other
end to the finger which is independently pivoted to the frame of the clip whereby
the pressure or weight exerted by the finger upon the cloth is reduced.
In carrying out the invention a gripper of any convenient form is pivoted to the
frame of the clip in the usual way and to the back of the gripper is pivoted or
connected a connecting link or links.
Behind the gripper is pivoted also the frame of the clip the finger which rests upon
the cloth to maintain the gripper open. The free or other end of the connecting
link or links is pivoted to the finger at a point some distance removed from the
axis upon which the finger is pivoted. The finger may be made with a projecting
arm of bell crank shape the length of such arm in relation to the length of the
finger being proportioned to give the desired weight or pressure.
By increasing or reducing the length of the leverage the weight of the finger upon
the cloth can be regulated or adjusted.

Improvements in Stentering Clips for Stretching Textile Fabrics.
I, EDMUND NUTTALL, of 58, Wyndham Street, Bury, in the County of Lancaster,
Engineer, 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 the gravity clips employed in stentering machines for
gripping or engaging the edges or selvages of the cloth the gripper or upper jaw
being connected with the finger which bears on the cloth so that the gripper or jaw
grips the cloth when it moves from under the finger; and the object of my

page_text: invention is to reduce the weight with which the fingers of such clips rest upon
the cloth due to the attachment of the gripper, or jaw, thereto. According to
my invention I combine with the clip. a link, or links, projecting behind the
gripper, the said link, or links, being pivotted, or connected, by a hinged connection,
at one end to the gripper and at the other end to the finger which is independently
pivotted to the frame of the clip. By this means the pressure, or weight, exerted
by the finger upon the cloth, is reduced.
Figures 1 and 2 represent in sectional elevation and Figure 3 in plan, a clip provided
with a link in accordance with my invention, Figure 1 representing the gripping
Jaw out of action and Figure 2 representing the said jaw engaged with the fabric to
be stretched.
A gripper A (of any usual, or convenient form) is, pivotted, or hinged, at a,
to the frame of the clip, which may be done in the usual way, and to the back of the
said gripper is pivotted, or hinged, at b, one end of a link B. To the frame of the
clip, and behind the gripper, A, is pivotted, or hinged at c, the finger C, which,
when it rests upon the cloth, maintains the gripper A, open by reason of the
connection of the said finger with the gripper, the other end of the said link B,
being pivotted, or hinged, to the said finger C, at a point 2 some distance from the
axis upon which the finger C is pivotted, or hinged. The distance between the
points cc² is so proportioned in relation to the length of the finger as to give the
desired weight, or pressure, of the finger on the cloth. By increasing, or reducing,
the distance between the points in relation to the length of the finger the
weight of the finger upon the cloth can be regulated, or adjusted, as desired.
I have shewn but one link B, on the drawings, but more than one link may be
similarly connected if desired.
Having now particularly described and ascertained the nature of this
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. The combination with clips for stentering machines of a link, or links,
pivotted, or hinged, at one end to the gripper, and at the other end to the finger, at
a point removed from that at which the finger is independently pivotted, or hinged,
to the frame of the clip substantially as, and for the purpose, hereinbefore
described.
2. A clip for stentering machines constructed as hereinbefore described and
illustrated in the accompanying drawings.
Dated this 10th day of April 1899.
