PROVISIONAL SPECIFICATION.
An Improved Arrangement of Clip for Holding Cloth in Machines
with Endless Chains for Stentering, Stretching, or Finishing
Cloth.
WILLIAM GEORGE HANNA of 24 Wellington Place Belfast Ireland Agent
do hereby declare the nature of this invention to be as follows:-
This improved arrangement of clip for holding cloth consists of a gripper or
straight-edge swung upon two arms beneath this gripper or straight-edge is a fixed
plate this swinging gripper or straight-edge and fixed plate together form the clip
for holding the cloth and they have in connection with them a lever which prevents
the swinging gripper from coming into contact with the cloth except at the edge or
selvage thereof the combination of this swinging lever with the gripper being the
main feature of this my invention.
The swinging gripper fixed plate and lever are designed to be carried on the
chain connected by hooks and eyes for which Letters Patent No. 775389 were
granted to the present applicant.
The centre or spindle upon which the gripper swings is further from the centre
of the chain than the edge of the gripper which is thus made to come into contact
with the cloth-that is between it and the fixed plate-in such a manner that the
gripper rests at an acute angle with the cloth when in contact therewith so that
the greater the strain on the cloth the tighter it is held and that without the aid
of springs.
On a centre or spindle between the chain and the centre upon which the gripper
swings is swung a lever that is slotted and which rests upon the cloth at the inlet
end of the machine whilst the cloth is behind the edge of the gripper. Moving in
this slotted lever is a projection which is attached to the back of the gripper the
slot in the lever and the position of the projection being so arranged that the edge
of the gripper cannot come into contact with the cloth until the edge or selvage
thereof has passed beyond the end of the slotted lever which then descends into a
hole in the plate and allows the edge of the gripper to come into contact with
the cloth.
When the swinging gripper is lifted by the usual mechanism employed for this
purpose the slotted lever is also lifted by means of the projection attached to the
back of the swinging gripper.
The swinging gripper is slotted so that the swinging slotted lever can pass
through it without contact where the paths of the gripper and lever cross each
other.
The swinging gripper and the slotted lever thus mutually control each other for
the swinging gripper cannot come into contact with or sieze hold of the selvage of
the cloth so long as the slotted lever rests upon the cloth and when the swinging
gripper is lifted so as to release the cloth it lifts the slotted lever above the plate so
that the cloth at the entrance can pass freely between the plate and the swinging
gripper and slotted lever.

WILLIAM GEORGE HANNA of 24 Wellington Place Belfast Ireland, Agent,
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 improved arrangement of clip for holding cloth is illustrated in the drawing
herewith in which
Fig. 1 is a top view.
Fig. 2 is an end view with clip open.
Fig. 3 is also an end view, but showing the clip closed.
The same letters of reference indicate the same or like parts in all the views.
This improved arrangement of clip for holding cloth consists of a gripper or
straight edge (a) swung upon two arms (2) beneath this gripper or straight edge (a)
is a fixed plate (c) this swinging gripper or straight edge (a) and fixed plate (c¹)
together form the clip for holding the cloth and they have in connection with them
a lever (b) which prevents the swinging gripper (a) from coming into contact with
the cloth (f) except at the edge or selvage thereof. The combination of this
swinging lever (b) with the gripper (a) being the main feature in this my invention.
The swinging gripper (a) fixed plate (c) and lever (b) are designed to be carried
on the chain connected by hooks and eyes for which Letters Patent No. 775389
were granted to the present applicant, it is also equally applicable to the ordinary
pivoted chain used in machines for stentering stretching or finishing cloth.
The centre or spindle upon which the gripper (a) swings is further from the
centre of the chain (c) than the edge of the gripper (a) which is made to come into
contact with the cloth (/) that is between it and the fixed plate (c') in such a
manner that the gripper (a) rests at an acute angle with the cloth when in contact
therewith, so that the greater the strain on the cloth the tighter it is held and that
without the aid of springs.
On a centre or spindle (6¹) between the chain (c) and the centre upon which the
gripper (a) swings, is swung a lever (b) that is slotted and which rests upon the
cloth (f) at the inlet end of the machine whilst the cloth is behind the edge of
the gripper (a)..
Moving in this slotted lever (6) is a projection (a¹) which is attached to the back
of the gripper (a) the slot in the lever and the position of the projection being so
arranged that the edge of the gripper (a) cannot come into contact with the cloth
until the edge or selvage thereof has passed beyond the end of the slotted lever (b)
which then descends into a hole in the plate and allows the edge of the gripper (a)
to come into contact with the cloth (f).
When the swinging gripper is lifted by the usual mechanism employed for this
purpose the slotted lever is also lifted by means of the projection attached to the
back of the swinging gripper.
The swinging gripper is slotted so that the swinging slotted lever can pass
through it without contact where the paths of the gripper and lever cross each
other.
The swinging gripper and the slotted lever thus mutually control each other, for
the swinging gripper cannot come into contact with or seize hold of the selvage of
the cloth so long as the slotted lever rests upon the cloth, and when the swinging
gripper is lifted so as to release the cloth it lifts the slotted lever above the plate so
that the cloth at the entrance can pass freely between the plate and the swinging
gripper and slotted lever.

page_text: 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
The arrangement and combination herein described and illustrated, of slotted
swinging gripper (a) projection thereon (a') and slotted lever (b) mutually controlling
each other as set forth.
