PROVISIONAL SPECIFICATION.
Improvements in Machines for Stentering or Finishing Woven
Fabrics.
We, Sir ARCHIBALD ORR EWING, Baronet, M.P. of Ballikinrain Castle, in
the County of Stirling, North Britain, and JOHN STOBO, Foreman Mechanic, of
Levanbank Works, Jamestown, in the County of Dumbarton, North Britain, do
hereby declare the nature of this invention to be as follows, that is to say :-
Our said invention relates to stentering or finishing machines of the kind in
which the woven fabric is held and carried through the machine by automatic
clips upon endless chains; and our object is to improve the action of certain parts
and to diminish frictional wear.
In carrying out our invention we fix or form on the upper or movable jaw of
each clip a part extending up beyond the axis on which the jaw hinges, this
extension being the part to be acted on for opening the jaw. And instead of
having as heretofore a fixed or stationary cam guide in contact with which the clip
jaw or a part acting thereon is brought at the parts of the machine whereat the
clips are to be opened, we provide a pulley rim or flange which turns on a centre
and moves with each clip jaw or part acting thereon whilst the same is in contact
therewith, so that rubbing friction is avoided. The clip chains pass round large
pulleys at the ends of the machine, and the flanges for opening the clips may be
formed or fixed on such pulleys, or they may be on separate disks or pulleys.
The upper jaw of each clip has formed in the same piece with it at its lower
part a projection acting as a gauge piece or feeler which rests on the fabric and
keeps the jaw from closing on it until the selvedge is drawn from under the feeler.
This feeler is shaped without sharp corners but with a nearly straight bottom edge
which rests on the fabric and is not liable to injure the fabric or get out of order
like some existing forms.
Dated this Thirteenth day of April 1892.

Improvements in Machines for Stentering or Finishing Woven
Fabrics.
We, Sir ARCHIBALD ORR EWING, Baronet, of Ballikinrain Castle, in the
County of Stirling, North Britain, and JOHN STOBO, Foreman Mechanic, of
Levenbank Works, Jamestown, in the County of Dumbarton, North Britain, 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 :-
This invention relates to stentering or finishing machines of the kind in which
the woven fabric is held and carried through the machine by automatic clips upon
endless chains; and our object is to improve the action of certain parts and to
diminish frictional wear.
In carrying out the invention we fix or form on the upper or movable jaw of
each clip, a part extending up beyond the axis on which the jaw hinges, and to
open the jaw we form on each clip chain pulley, at the end of the machine, or on a
separate disk a pulley rim or flange which moves with and acts on the upwardly
extending part of each movable clip jaw. The upper jaw of each clip is provided

straight bottom edge, to keep the slip jaw from closing until the selvedge is
drawn from under the feeler.
And in order that the said invention and the manner of performing the same
may be properly understood, we hereunto append a sheet of explanatory drawings,
to be hereinafter referred to, and showing the improvements.
Figure, 1, of the drawings is a plan, and Figure, 2, a sectional side elevation of
a part of a stentering or finishing machine, as fitted with the improvements.
Figure, 3, is a side elevation of the improved clip the movable jaw of which is
shown, as open, in dotted lines. In these drawings the same reference letters and
numerals are used to mark the same or like parts wherever they are repeated.
Figures, 1, and, 2, show the parts which carry and act on one of the two endless

form on the upper or movable jaw, A, of each clip, B, a part, C, extending up'
beyond the axis on which the jaw hinges, this extension being the part to be
acted on for opening the jaw to release the fabric. And instead of having as
heretofore a fixed or stationary cam guide, in contact with which the clip jaw, A,
or a part acting thereon is brought at the parts of the machine, whereat the
clips, B, are to be opened, we provide a pully rim or flange, D, which turns and.
moves with the clips, when they are in contact therewith so that rubbing friction
is avoided. The disk, D, is of such a size and is so placed that as the movement
of the endless chain brings each clip along, the projection, C, of each clip
encounters the edge of the disk and is thereby moved so as to open the clip.
The clip chains, E, pass round large pulleys, F, at the ends of the machine, and
which are arranged and worked in the ordinary way; and the flanges or disks, D,
for opening the clips, B, are formed or fixed on these pulleys, or if desired they
might be on separate disks or pulleys.
The upper jaw, A, of each clip, B, has formed in the same piece with it at its
lower part a projection acting as a gauge piece or feeler, G, which rests on the
fabric when it first enters the clip with its edge considerably within the jaw, A,
and this feeler prevents the jaw from closing, until the selvedge is drawn from
under the feeler. The feeler, G, is shaped without sharp corners and with a nearly
straight bottom edge, G 1, which rests on the fabric, and is not liable to injure
the fabric, or get out of order like some existing forms.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
1. In machines for stentering or finishing woven fabrics providing a flange, or
disk, or pulley rim, for opening the clips and arranged to move with the clips
when acting on them, substantially as and for the purposes hereinbefore described.
2. In clips for machines for stentering or finishing woven fabrics, a feeler or
gauge piece shaped as bereinbefore described and as shown in Figure, 3, of the
accompanying drawings.
