Improved Clip or Holder for Use in Machinery for Tentering,
Stretching. and Drying Fabrics.
We, HORATIO CLIFFE and WILLIAM CLIFFE, of the Firm of Elkanah Hoyle and
Sons Limited, of Waterside Works, Halifax, in the County of York, Millwrights,
Engineers and Iron Founders, do hereby declare the nature of this invention to
be as follows, that is to say:-
It relates to clips or holders formed upon or secured to the travelling chains
of tentering, stretching and drying machinery used in the treatment of fabrics
and consists in constructing the said clips or holders in such a manner that they
will grip and firmly hold the fabrics under treatment in a desired manner during
and notwithstanding the vibratory and other actions of the machinery, while
their actions of gripping and releasing their hold of said fabric at the proper
place and time are automatically performed.
In carrying our invention into effect we form the lower jaw of the clip or holder
to have its incorrodible plate attachment and slots for adjusting the actions of
the upper jaw upon the fabric as heretofore, the upper jaw being mounted upon
projections on the arm of the lower jaw so that its gripping edge may engage
with the selvage of the fabric as desired.
This upper jaw is made to descend by gravity into contact with the fabric
being treated, prongs or projections upon its lower edge being arranged to act
through the slots in the lower jaw so that the gripping actions on the fabric are
not commenced unless and until the proper width of selvage is beneath the
upper jaw.
Pivotted to appropriate bearings arranged in an appropriate position relatively
with those upon which the upper jaw is mounted is a supplementary jaw or lock-
ing lever which is constructed and formed so that its own weight will cause it to
engage with the upper jaw when this latter has moved into position for gripping
the fabric, its said engagement being of such a nature as to enable it to hold said
upper jaw firmly in position until the desired position on the machine is reached
when the actions of cam pieces or cam plates will automatically release same
as desired.

We, HORATIO CLIFFE and WILLIAM CLIFFE, of the Firm of Elkanah Hoyle and
Sons Limited, of Waterside Works, Halifax, in the County of York, Millwrights,
Engineers and Ironfounders, 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, that is to say:-
It relates to clips or holders formed upon or secured to the travelling chains
of tentering, stretching and drying machinery used in the treatment of fabrics
and consists in constructing the said clips or holders in such a manner that they
will grip and firmly hold the fabrics under treatment in a desired manner during
and notwithstanding the vibratory and other actions of the machinery, while
their actions of gripping and releasing their hold of said fabric at the proper
place and time are automatically performed.
In order that our said invention may be readily understood, we have hereunto
appended sheets of drawings illustrative thereof, in which :-
Fig. 1 is a front elevation of our improved clip or holder fixed to its travelling
chain.
Figs. 2 and 3 are end and sectional end elevations respectively of parts illus-
trated by Fig. 1.
Fig. 4 is a plan view of parts shown by Fig. 1.
דין
Fig. 5 is a part sectional end elevation of the clip and the framework sup-
porting it, and illustrates a method whereby the movable jaws may be auto-
matically raised or opened.
Fig. 6 is a sectional elevation, drawn to a reduced scale, of the incline.or
cam part illustrated by Fig. 5.
Similar letters and figures of reference indicate similar parts throughout the
several views:
In carrying our invention into effect, we form the lower jaw a of the clip or
holder (which is formed integrally with or mounted on the travelling chain m)
to have its incorrodible plate 6 (attached to said lower jaw by the bolt c) and the
slots'd for adjusting the actions of the upper jaw e upon the fabric as heretofore,
said upper jaw e being mounted upon the pin or shaft e¹ which takes within
openings formed in the projections f f extending from the arm a of the lower
jaw ȧ, so that the gripping edge e² of said upper jaw may'engage with the
selvage of the fabric as desired.
1
The said upper jaw e is formed so that it will, when free to do só, descend by
gravity into contact with the selvage of the fabric g, while the prongs or pro-
jections formed upon its lower edge are arranged to act through the slots d
in the lower jaw a, so that the gripping actions are not commenced unless and
until the proper width of selvage is beneath said upper jaw e.
Pivotted on the pin h¹ which is preferably mounted in the projections ƒ ƒ¹
as shown, or may be pivotted in separate bearings if desired, we mount a supple-
mentary jaw, or locking lever h which is formed so that its own weight will,
when it is free, cause it to descend until its surface 2 comes into contact or
engages with the surface of the upper jaw e, when this latter has moved into
its lower position for gripping the fabric g, in this manner the upper jaw e is
held so that it cannot be raised or displaced by any tension on the fabric g,
or by the vibrations of the machine.
At the feeding end of the stretching, tentering or like machine, 'or at that part

page_text: where the clips lay-hold-of the fabric to be operated upon, it is necessary that
the upper jaws e and their locking levers h should be raised from their lower or
closed positions in order that the fabric g may be passed beneath said upper
jaws e. This may be effected by the stationary double cam or incline piece n,
preferably mounted on the bearings o for the travelling chain m, its upper cam
surface n being for the reception of the arm h³ of the locking lever h, and the
lower cam surface n is for the arm of the upper jaw e to rest upon. It will
thus be seen that as the clips are carried along by their travelling chains m
(one series of which only is shown by Fig. 5, although there is another series of
chains and clips to receive the fabric at the opposite side of the machine) in
the bearings o, their upper jaws and locking levers will be automatically opened
and then allowed to fall into their closed or locked positions at the required time
and place of their travel.
At the delivery end of the machine, or the part where the fabric is released
from clips, one cam surface n¹ only is necessary to raise the locking levers h,
as the fabric may then readily pass from between the jaws a and e.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. A clip or holder for use in machinery for tentering stretching and drying
fabrics, the same being constructed and arranged to operate substantially as
herein specified.
2. In machines for tentering, stretching and drying fabrics, clips or holders
and means for operating same, substantially as herein specified.
