We SAMUEL CUNLIFFE LISTER of Manningham Mills Bradford in the County
of York Manufacturer and JosE REIXACH of the same place Manager for the
firm of Lister and Co at Manningham Mills aforesaid do hereby declare the
nature of our invention for "IMPROVEMENTS IN MACHINERY FOR CUTTING OR
SEVERING DOUBLE PILE FABRICS WOVEN FACE TO FACE AND IN THE MANU-
FACTURE OF DOUBLE PILE FABRICS TO FACILITATE THE CUTTING OPERATION to
be as follows:-
"
In machinery for cutting or severing double pile fabrics we employ according to
this invention moveable rails the one mounted on the edge of the top velvet or
gauge rail and the other mounted on the edge of the bottom velvet or gauge rail
in such manner that they can be slidden upwards or downwards to open or close
the angle of the two pieces whilst being cut or sovered by a knife made to travel
in front of and equidistant from the said moveable rails-and for the purpose of
securing and keeping an even and regular tightness across the unsevered double
pile fabric as it moves up to the point at which the pile is to be cut or severed we
cmploy two double pile fabric temples such as employed by us in looms for
weaving double pile fabrics and we weave the double pile fabric with an additional
or second binding thread between the top and bottom piece at a suitable distance
from the usual or outside binding threads, the latter binding threads being severed
during the process of weaving whilst the former binding threads are left intact
during this process and are not severed until the pile is cut in the cutting or
severing machine.

Pile Fabrics Woven Face to Face, and in the Manufacture
of Double Pile Fabrics to Facilitate the Cutting Operation.
We SAMUEL CUNLIFFE LISTER of Manningham Mills, Bradford in the County of
York Manufacturer and JOSÉ REIXACH of the same place Manager for the firm
of Lister & Co at Manningham Mills aforesaid 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:-
In machines for cutting or severing double pile fabrics we employ according to
this invention moveable bars the one mounted on the edge of the top velvet or
guage rail, and the other mounted on the edge of the bottom velvet or guage rail,
in such manner that they can be slidden. upwards or downwards to increase or
diminish the distance the two pieces are held apart whilst the pile is being cut or
severed by an endless knife made to travel in front of and equidistant from the
said moveable rails, and for the purpose of securing and keeping an even and
regular tightness across the unsevered double pile fabric, as it moves up to the
point at which the pile is to be cut or severed, we employ two double pile
fabric temples such as employed by us in looms for weaving double pile fabrics and
we weave the double pile fabric with an additional or second binding thread
between the top and bottom piece at a suitable distance from the usual or outside
binding threads, the latter binding threads being severed during the process of
weaving whilst the former binding threads are left intact during this process and
are not severed until the pile is cut in the cutting or severing machine.
In order that our invention may be fully understood we proceed to describe the
drawings hereunto annexed.
Figure 1 is a side view of part of the frame of the cutting machine and of the
guage rails and the guide rail for the endless knife-the knife is shewn only in
section.
Figure 2 is a cross section of the guide rail for the endless knife.
Figure 3 is a plan view of one of the temples and of a portion of one side of the
cloth passing over it.
Figure 4 is a section of a portion of the cloth shewing one side selvage with the
two sets of temple loops the outer set of temple loops is shewn to have been
severed by the loom temple whilst in the process of weaving and the other set of
loops remaining unsevered to be used on the cutting machine.
Figures 5 and 6 are front views of the top and bottom velvet or guage rails with
their moveable guage bars-they shew the way in which we provide for moving
the guage bars towards or away from one another.
Figure 7 is a section of the top velvet or guage rail with its moveable bar and
Figure 8 is a section of the bottom velvet or guage rail with its moveable bar,

page_text: A is part of the framework of the machine B is the guide rail for the endless
knife. The guide rail extends across the machine and supports the portion of the
knife which is acting to cut the pile-The endless knife also passes over two
wheels in the ordinary way one at one side of the machine the other at the other
side and receives motion from one of these wheels which is on the driving shaft of
the machine. C (Figure 1) is the endless knife in cross section. D is the top
velvet or guage rail and E the bottom velvet or guage rail. F is the temple shown
to be carried by the lower guage rail E-there is one such, temple carried by each
end of the guage rail-The temples can be slidden along the rail and can be moved
towards or away from one another by screws G as seen in Figures 1 and 3-so as
to regulate the tension on the cloth as it comes up to the point where the pile is to
be severed. H. H¹ are the moveable bars of the upper and lower guide rails.
J. J₁ are draw bars for raising or lowering the bars H. H³. Each of the bars H. H',
has inclines K. cut in it at intervals whilst the draw bars J. J' have corresponding
inclined projections L which rest against the inclines K so that when the draw
bars J. J are moved endwise the bars H. H' will be raised or lowered. In the
upper bar II are inclined slots H2 of the same inclination as the inclines K and L.
J' are studs carried by projections on the upper draw bar J to enter these slots
and hold the inclines K of the upper bar up to the inclined projections on the
upper draw bar.
To give endway movement to the bars J. J each of these bars has a screw
stem M extending from it on to which screws a nut N which lies between two lugs
projecting from the fixed guide rails D. E. so that the end way movement may be
given by turning the nut N. O. O. are screws for fixing the moveable guage bars
when they have been adjusted in position. In this way the guide bars can be set
nearer to or further away from one another to adjust the tension on the pile threads
as they are brought up to the knife to be severed.
The double pile fabric to be cut is woven with two binding threads passing
between the side selvages of the upper and lower cloths at each side of the cloth-
these threads we weave into the cloths in the same way as is described in the
Specification of a former patent granted to us N° 3327 in the year 1878 for weaving
in a single binding thread.
In Figure 4 the pile threads of the double pile fabric are marked P-the
outer binding thread which passes from the outer edge of the selvage of the one
cloth to the outer edge of the selvage of the other is marked these serve to hold
the cloth distended as it is being woven in the loom and are cut by the loom
temples. The other binding thread R which lies centrally between the outer edge
of the selvages and the pile threads remains uncut as shewn in Figure 4 for the
temples of the cutting machine to hold on to.
The operation of cutting the pile of the double pile fabric in the cutting machine
is as follows. As the fabric is drawn forwards towards the knife C the binding
threads R come on the outside of the temples and the fabric becomes stretched by
tle incline of this outer surface and is so kept free from creases during the cutting
operation. As the loops of the binding thread come to the curved bend at the end
of the temple they are severed by the outer edge of the temple being there
sharpened.
After the knife has divided the pile the upper cloth, is led away over a roller S
shewn by dotted lines in Figure 1 and the lower cloth over a similar roller-these
rollers have a continuous revolving motion imparted to them whenever the knife C
is revolved.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the saine is to be performed we declare that what
we claim is
1. The use in combination of the endless knife and guide rails D and E with

page_text: 2. The use in combination of the endless knife and guide rails D and E with
their adjustable guide bars substantially as described.
3. The manufacture of double pile fabrics with binding threads passing from the
selvage of the upper to the selvage of the lower cloth centrally between the pile
and the outer edge of the selvages to form loops for the temples of the cutting
machine to hold on to when the pile is being cut substantially as described.
