facturer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object improvements in the manufacture of carpets and
other fabrics.
The objects of my invention are First, to weave pile fabrics without wasting pile
threads by allowing them to lie unused in the body of the fabric as occurs for example
in Brussels carpets.
I cause the pile threads for the entire width of the fabric to be arranged in duo
order in a slay or like apparatus. I provide also a clip or clips by which the threads
projecting from the slay can be nipped or held. The clip apparatus is of a length to
hold all the threads from end to end of the slay. Jacquard or other selecting apparatus
is also employed. The threads selected by the Jacquard are made to project further
through the slay than the other threads, and as so arranged they are taken hold of by
the clip. The clip then places the fringe of selected threads projecting from it amongst
the warp or chain of the fabric and by the insertion of the weft the fringe becomes
tied in.
A knife then divides the threads so tied into the fabric and liberates the clip which
then returns for another selected fringe to be prepared.

page_text: I, HENRY FAWCETT of 10 Nowgate Street in the City of London, and of Kidder-
minster Carpet Manufacturer, 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 invention has for its object improvements in the manufacture of carpets and
other pile fabrics.
The object of my invention is to weave pile fabrics without wasting pile threads by
allowing them to lie unused in the body of the fabric as occurs for example in Brussels
carpets.
I cause the pile threads for the entire width of the fabric to be arranged in due
order in a slay or like apparatus. I employ Jacquard or other selecting apparatus to
select the threads required. I also provide a clip or clips by which the threads selected
by the Jacquard can be nipped or held. The clip apparatus is of a length to hold all
the threads from end to end of the slay. The threads selected by the Jacquard are
taken hold of by the clip and placed amongst the warp or chain of the fabric and by
the insertion of the weft the fringe becomes tied in.
A knife then divides the threads so tied into the fabric and liberates the clip which
then returns for another selected fringe to be prepared.
The drawings annexed shew parts of apparatus constructed to weave carpets or other
pile fabrics in the above manner.
Figure 1 is a vertical longitudinal section looking from one side of the loom and
Figure a similar longitudinal section looking from the opposite side of the loom.
Diagrams A, B, C and D illustrate the action of the mechanism.
AA' is a slay or holder in which the ends of the pile warps B are held. C, D, are
the chain or ground warps, E E' is the clip by which the pile warps selected by the
Jacquard are placed amongst the chain warps to be woven in. F is a carrier bar by
which the ends of the selected pile warps are placed into the clip E E'. G is a carrier
bar by which the selected pile warps after being woven into the fabric and after their
ends which have been woven into the fabric are severed off from them are placed back
into the bottom clip or holder A A¹. H' is a reed carried by the batten H it is com-
posed of a series of blades held at their upper end.
The action of the parts is as follows:
At a time when the ends of all the pile warps are held in the bottom clip A A' the
pile warps are selected by the Jacquard and the selected threads raised up through
the chain or ground warps as indicated in diagram A. The top carrier bar F is then
passed across the loom so as to come below the selected pile warps between them and
the chain or ground warps. The carrier bar F is then moved forwards towards the
front of the loom at the same time that the clip A A¹ is opened. All threads lying across

page_text: the top carrier bar F are then drawn out of the clip A A¹ and carried to the clip E E¹
by the bar. The parts are then in the position shewn by Diagram B. The carrier
bar F passes between the two jaws of this clip carrying the ends of the threads along
with it. The jaws E E¹ then close upon and nip the threads lightly and are moved
forwards until they hold the extremities of the selected threads just above the fell of
the fabric. The cords of the Jacquard which hold up the selected threads are at the
same time lowered so that a shoot of weft may be passed through the warps over the
selected pile warps. Afterwards the batten beats up and the parts are in the position
shewn by Diagram C. Subsequently the jacquard lifting board rises and a second
shoot of weft is laid in under the pile warps and the batten again beats up and the
jacquard lowers the selected threads to lay them on to the lower carrier bar G. When
the shed of the chain or ground warps has been again changed the ordinary tying in
shoot is inserted and the batten again beats up. At this time also the selected pile
threads are severed from their ends which have been tied into the fabric by any
ordinary cutting mechanism leaving the ends of the lengths cut off from the pile
threads projecting from the surface of the fabric and forming part of the pile.
The threads as they are laid by the Jacquard on to the top of the carrier bar Gas
shewn in Diagram D are caught by it as herein after explained and when the bar
is moved forward into the position shewn in Diagram A it carries the ends of the
threads into the clip A A-where they are again retained and then another selection
is made by the Jacquard.
The way in which I open and close the clips and move the upper clip to and fro
and in which I give motion to the carrier bars is shewn in the drawings.
For passing the shoots of weft through the sheds a wire or other suitable motion
may be used instead of the usual shuttle motion.
No shuttle motion is shewn in the drawings or any knife motion for severing the
pile threads as they may be of any suitable construction and mode of action.
The batten H has its backward and forward motion given to it by lever arms I'
acted on by a cam I-it has also a rising and falling motion given to it. Its lower
end is for this purpose jointed to arms on an axis J-this axis has fast upon it
another arm J which by a link is coupled to one end of a lever J* the opposite
end of which is acted on by a cam J on the cam axis.
The clip E E' has motion given to it in the following manner :-
One blade E of the clip is carried by arms fixed to a rod K which can turn in
bearings carried by arins K which turn on an axis at K2. The rod K has also fixed
to it another arm K³ in which is a slot into which enters a pin at one end of a link K
the other end of which turns on a fixed centre at K³.
The other blade E' of the clip is carried by arms fixed to a rod L which turns
in bearings in short links L2 which can turn about the rod K. The rod L has
another arm L³ fixed to it which by a link L is coupled to the upper end of a
lever L the lower end of which is acted on by a cam L on the cam shaft. The
arms K' have a swinging to and fro motion given to them by their being coupled
by links M to a lever M which is acted on by a cam M on the cam shaft.
The lower clip or slay A A' is opened and closed in the following manner :-
The upper bar A is fixed-the lower bar A¹ is coupled to arms N' which are fixed
to a rod N2 capable of being turned in fixed bearings-this rod has another arm N³
fixed to it which by a link N is coupled to one arm of a lever No the other arm
of which is acted on by a cam N on the cam shaft.
The way in which motion is given to the upper carrier bar F is shown separately
at figures 3 and 4.
It is carried at one end by a slide O' which can be traversed to and fro along
the top rail of a frame 02 which is at one side of the loom at right angles to it.
The frame O at its lower end is fixed on an axis 03-A rocking motion is given to
this axis by its upper end being coupled by a link to the upper end of a lever O'
the lower end of which is acted on by a cam O on the cam shaft.
The slide O¹ is traversed to and fro at the required times along the top rail of the
frame O2 by a pin upon it passing into a slot in the upper end of a lever P¹ which

page_text: turns on a pivot at its lower end and is coupled by a link P2 to a lever P3 which is
acted on by a cam P on a cam shaft P4 which is driven at the same speed as or double
the speed of the main cam shaft.
When the carrier bar F has by the movement given to the slide O¹ been passed
across the loom its end is received on to the top of a projection R¹ on an arm R which
is fixed to the axis 0³ of the frame O2 and therefore rocks to and fro with the frame.
The lower carrier bar G is moved to and fro by links S¹ coupled to one arm of a
rocking lever S² the other arm of which is coupled by a link to a lever S³ which is
acted on by a cam S on the cam shaft.
The upper edge of the bar G has numerous recesses formed in it as shewn in
Figure into which the pile warps enter when they are lowered by the jacquard to be
returned to the lower clip A A¹. The bar has also jointed to it a number of fingers G
which are made to turn into the position shewn in figure 5 after the warps have been
laid into the recesses so as to retain the warps therein. At other times they are turned
into a vertical position to leave the recesses open at the top. The shape of the various
cams for giving the above described movements to the various parts is shown at
Figure 6.
In order to be able to simultaneously rock all the fingers G¹ their lower ends are as
shewn jointed to a bar G² which may be drawn by a spring into position to cause the
fingers to close over the recesses.
When the bar G has been moved to its forward position the bar G2 may be made to
come against an incline and be thereby moved endwise and caused to turn the fingers
into their vertical position and the bar G may then be caught by a spring catch and
be retained by it until the bar G has been moved to its back position when the catch
may be released by its being brought against a fixed stop so as to then allow the
fingers to close over the recesses in the bar.
I would state that I do not restrict myself to the various means herein before
described for giving movement to the operative parts of the mechanism as these may
be considerably varied.
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
1. The construction of looms for weaving carpets and other pile fabrics in such
manner that the ends of the pile threads are held in a holder and when required to be
woven in selected by jacquard or other selecting apparatus and placed into a clip by
which their ends are carried to the fell of the fabric so that they may be woven in
and the woven in ends afterwards severed off and the pile threads returned to the
holder in which they were previously held.
2. The construction of looms for weaving carpets and other pile fabrics substantially
as herein before described and illustrated in the drawings annexed.
