Improvements in Clips for Tentering, Stretching or Drying
Machinery for Fabrics.
We JOSEPH HORTON and WILLIAM HORTON both of West Vale near Halifax in the
county of York Engineers and machine Makers, do hereby declare the nature of
this invention to be as follows:-
The object of our invention is to construct a safe locking clip, which overcomes all
vibration when travelling the length of the machine and retains its firm grip upon
the cloth whether tight or slack, it automatically gauges the proper distance from the
edge of the piece so making a straight selvedge, it automatically closes upon the edge
of the piece when feeding, and automatically opens at the end of its travel, the clips
being suitable either for a return machine or for a gas tentering machine which allows
the piece to be taken off at the opposite end of the machine.
When desired eccle plates can be used on this chain in place of the aforesaid clips.
To each link of the chain we attach a plate with slots, at the side of the plate we
pivot a faller consisting of an arm to which is pivotted a grip, jaw and guage, the
guage passing into the slots beforenamed and so guages the proper distance for
gripping the edge of the piece, at the back of the pivotted arm is a second spring
pivotted locking arm wedge or key which is automatically opened and closed by
suitable projections on the machine.
The piece is placed forwards on the plate the faller, grip, jaw and guage is dropped
down and as the chain is travelling up the incline the piece is gradually withdrawn
from the clip until the edge is the required distance when the locking arm falls into
position and firmly secures the piece and locks it.

Improvements in Olips for Tentering, Stretching or Drying
Machinery for Fabrics.
We JOSEPH HORTON and WILLIAM HORTON both of West Vale near Halifax in the
county of York, Engineers and Machine Makers, 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:-
The object of our invention is to construct a safe locking clip which overcomes all
vibration when travelling the length of the machine, and retains its firm grip upon

page_text: the cloth whether tight or slack, it also automatically guages the proper distance.
from the edge of the piece, so making a straight selvedge, further, our improved clip
automatically closes upon the edge of the piece when feeding, and automatically
opens and releases the piece at the end of its travel; the clips are suitable either for
a return machine, or for a gas tentering machine, which allows the piece to be taken 5
off at the opposite end of the machine.
Fig. 1 is a side view of our improved clip showing the same open and
locked.
Fig. 2 is a side elevation of our improved clip showing the faller grip and guage
resting upon the piece, and the locking arm being depressed.
Fig. 3 is a plan of our improved clip showing position of same when the grip jaw
has taken hold of the cloth or fabric.
Fig. 4 is a side elevation of Fig. 3. Fig. 5 shows mechanism for automatically
locking and unlocking the clip on a reduced scale also for operating upon or knocking
the faller over on to the cloth.
Upon the arm A of each link B of the chain, we attach a plate C, with slots D,
pivotted upon this arm A in suitable brackets E, is a faller consisting of arms F to
which is attached or pivotted a grip jaw or clip G, and guage H, the gunge passing
into the slots D before-named, and so gauges the proper distance for gripping the
edge of the piece J.
At the back of this clip is a spring pivotted locking arm K, wedge, or key, which
is operated upon automatically by a semicircular plate L (attached to the machine
frame) as the said clip travels with the piece, for releasing and locking the clip either
open or closed.
This locking arm or key K is also pivotted upon the arm A, and has at one end a
rounded heel M, which when the clip G is opened, drops behind a similar heel N
upon the boss of the grip jaw, or clip arms F, and locks the clip G in this position
Bee Fig. 1.
When the locking arm K is depressed, the clip G is released, and comes in contact
with a second bracket or plate P, which causes the second clip to fall upon the cloth,
the cloth being gradually withdrawn by the ordinary taper or expanding chain race
or plane at the feeding end of the machine until the gauge H drops within the
recesses D in the plate C, when the grip or clip immediately takes a firm hold of the
cloth, and is then locked by means of the rounded face of the heel M engaging with
a similar concave recess upon the heel of the clip, see Fig. 4. tension is put upon the
locking arm K by spiral springs Rattached to wings S, upon the locking arm K, and
projections T, upon the arm A.
The action is as follows.-In an ordinary tentering machine, the piece J is placed
forwards on the plate C, the clip G being open and locked, the pivotted locking
arm K comes in contact with the semicircular plate L which depresses it, until it
passes under the plate as shown in dotted lines on Fig. 1, Bo releasing the clip G which
is knocked over on to the piece by the plate P, (this plate is adjustable to the
position of the faller so as to operate upon the same in an effectual manner), and as
the chain is travelling the piece is gradually withdrawn from the clip until the edge
is in the required position. when the guage H drops within the recesses D in the
plate Cand the clip takes a firm hold of the piece or cloth, this is accomplished
after the locking arm K has passed under the plate L, so that when the clip takes
hold of the cloth, the rounded heel M of the locking arm, immediately engages with
the concave recess on the heel N of the clip and locks it, see Fig. 4. Owing to the
shape of the plate L, the locking arm K is gradually depressed and gradually resumes
its original position, so preventing any unusual or sudden strain upon the working
parts.
For automatically releasing the piece underneath the machine, a second semi-
circular plate similar to the one before described is fixed upon the frame of the

page_text: machine, this plate acts upon the locking arm K as before described; when the said
arm K is passing under the plate the clip G is released and opens by gravitation, as
the arm passes from under the plate it rises and locks it. The clip is held open
until the next piece is put in when it is automatically released, takes hold of the
fabric, and is again locked as before described.
In gas tentering machines that is, where the piece is dried with gas in place of hot
air or steam pipes we preferably release the piece on the top, and depress the locking
arm K by means of a semicircular sheet or cover placed around one side of each chain
wheel, the edge of this cover projects so that as the chain passes over the wheel the
locking arm comes in contact with the plate and is depressed until the clip opens as
before described, the arm then passes underneath and out of contact with the plate
and locks the clip in position.
Having now particularly described aud ascertained the nature of this invention
and in what manner the same to be performed we declare that what we claim
is :-
1. Clips for the chains of tentering stretching and drying machinery constructed
with faller or grip jaw G, mounted upon pivotted arms F, plate C having slots D,
guage H, operated locked and unlocked automatically in the manner and for the
purposes substantially as shown and described.
2. Clips for the chains of tentering stretching and drying machinery, with
grip jaw G guage H, pivotted arms F having heel N, and pivotted spring locking
arm K with heel M, for automatically locking and unlocking the clip, in the manner
and for the purposes substantially as shown and described.
3. In clips for the chains of tentering stretching and drying machinery the com-
bination with a grip jaw G, upon pivotted arms F, guage H, and spring locking
arm K, of a semicircular plate L and plate P, or their equivalents, for automatically
opening, closing, locking and unlocking the said clip, in the manner and for the
purposes substantially as shown, and described.
