Improvements in Chain Clips for Stentering, Drying, and Finishing
Machines.
I, ALEXANDER COCHRAN ADAM, of the firm of William Adam and Son, of
Milnbank, Townmill Road, Glasgow, in the County of Lanark, North Britain,
Bleachers, Dyers, and Finishers, do hereby declare the nature of this Invention to he
as follows; that is to say :-
My said Invention relates to machines for stentering, drying, and finishing woven
fabrics, through which machines the fabrics are conveyed by endless chains the links
of which are made with clips for taking hold of the selvedges of the fabrics; and the
object of my Invention is to improve the construction of the clips and to make them
so that their holding power does not become diminished with use.
In an ordinary clip the upper jaw is pressed downwards on the lower jaw by the
action of a spring and if the spring is not strong enough or has become too weak from
use, the strain on the fabric makes it slip out from between the jaws, the movement
which the strain tends to impart to the upper jaw being in the direction of opening it.
In carrying out my Invention, instead of arranging the movable jaw so as to open
by rising off the other jaw, I arrange it to open by moving inwards from the other
jaw towards the link; and I give a bevilled gripping surface to the other jaw, which
surface the gripping edge of the movable jaw encounters when moved outwards.
With this arrangement the strain or pull of the fabric makes the movable jaw close
more firmly against the other jaw. The clip is thus rendered self-holding, and the
fabric is held the more tightly the stronger its strain is. A spring of any convenient
kind may be applied to the movable jaw to close it, but need not be of any great
strength, as the self-holding action is sufficient to keep the jaw closed.
When the clips are applied to machines for drying woven fabrics by means of heated
air admitted into an enclosed space of which the fabric forms the top boundary, the
clips are formed with shields on their undersides to diminish the escape of heated air
between the clips and the links to which they are attached.

Improvements in Chain Clips for Stentering, Drying, and Finishing
Machines.
I, ALEXANDER COCHRAN ADAM, of the firm of William Adam and Son, of
Milnbank, Townmill Road, Glasgow, in the County of Lanark, North Britain,
Bleachers, Dyers and Finishers, 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:―
My said Invention relates to machines for stentering, drying and finishing woven
fabrics, through which machines the fabrics are conveyed by endless chains the links
of which are made with clips for taking hold of the selvedges of the fabrics; and
the object of my Invention is to improve the construction of the clips and to make
them so that their holding power does not become diminished with use.
In an ordinary clip the upper jaw is pressed downwards on the lower jaw, by the
action of a spring and if the spring is not strong enough or has become too weak
from use, the strain on the fabric makes it slip out from between the jaws, the move-
ment which the strain tends to impart to the upper jaw being in the direction of
opening it.
In my improved clip the movable jaw is arranged to open by moving inwards from
the other jaws towards the link, instead of opening by rising off the other jaw; and
I give a bevilled gripping surface to the other jaw. In some cases the clips are
formed with shields on their undesides to diminish the escape of heated air.
And in order that my said Invention and in the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings to be
hereinafter referred to and showing my improved clip.
Figure, 1, in the accompanying sheet of drawings is an end elevation showing
the holding jaw closed. Figures, 2, and 3, are, respectively a front elevation and an
inverted plan of two clips jointed together; and figure, 4, is a transverse vertical
section showing the holding jaw open. In these drawings the same reference numerals
are used to mark the same or like parts wherever they are repeated.
In carrying out my Invention each of the links, 5, forming the endless chain are
formed, as usual, with a single joint eye or lug, 6, at one end and with a pair of joint.
eyes or lugs, 7, at the other end and the links are connected together by joint pins in
the usual manner. The upper movable jaw, 8, of the clip is hinged by means of
lugs, 9, and a pin, 10, to two brackets, 11, formed in a piece with a rib, 12, on the
link, 5. The jaw, 8, is made with a shank, 13, to be acted on by the stationary cams
or inclines of the machine for opening and closing the jaw, the opening taking place
by the jaw, 8, moving inwards from the other jaw, 14, towards the link, 5. The
jaw, 14, is also formed in a piece with the rib, 12, and it is formed with a bevilled
gripping surface against which the movable jaw, 8, closes when moved outwards.
With this arrangement the strain or pull of the fabric held as shown at, 16, in

page_text: figure, 1, makes the movable jaw, 8, close more firmly against the other jaw, 14. The
clip is thus rendered self-holding, and the fabric is held the more tightly the stronger
its strain is. A spring, 15, is applied to the movable jaw, 8, to close it, but need not
be of any great strength, as the self-holding action is sufficient to keep the jaw
closed.
The jaw, 14, is so shaped that it forms a shield on the underside of the clip which
is of special advantage when the clips are applied to machines for drying woven
fabrics by means of heated air admitted into an enclosed space of which the fabric
forms the top boundary, the escape of heated air between the clips and the links to
which they are attached being by means of these shields greatly diminished.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is :-
1. The combination of parts forming an improved chain clip for stentering, drying,
and finishing machines substantially as herein before described and shown in the
accompanying drawings.
2. Making a chain clip with a movable jaw arranged to open inwards and in closing
to move outwards against a bevilled surface on the other jaw substantially as and for
the purposes herein before described.
3. Forming chain clips with shields on their undersides substantially as and for the
purposes hereinbefore described.
