PROVISIONAL SPECIFICATION.
Improvements in Looms for the Manufacture of Tufted or other
Fabrics.
We, BRINTONS LIMITED, of Kidderminster, in the County of Worcester, Carpet
Manufacturers, and THOMAS GREENWOOD of the Shrubbery, Wolverley, near
Kidderminster aforesaid, Mechanic, do hereby declare the nature of this invention
to be as follows:-
Our invention has reference to looms for the manufacture of tufted or other
fabrics and more particularly of carpets or fabrics of the kind known as Axminster,
Royal Axminster or Moquette.
According to one part of our invention, we employ, in looms in which grippers
are used to feed tuft yarns to the fabric that is being woven, an arrangement
comprising a lower comb and an upper comb or bar at or near the fell of the cloth
as about to be described. The. tufts of yarn are laid by the grippers upon the
lower comb which is horizontal or approximately so; then after the weft has been
shot the lay and reeds beat up and bind the tufts against this comb; next the
grippers open, release the tufts and rise out of the shed and in so doing somewhat
lift up what were previously the gripped ends of the tufts. Then the upper comb
or bar with a combined upward and backward movement followed by a downward
and forward movement comes behind the tufts and brings the previously gripped ends
into a vertical position in which they are then'secured by another shoot of weft, the
dead warp having been meanwhile raised.
Another part of our invention consists of a double reed, that is to say, a' reed
having two dents placed one behind the other. Each warp thread passes at one
side of the back' dent of the corresponding reed' and then at the other side of the
front dent of the same reed being in' fact threaded through 'between the back and
front dents. These double reeds have the effect of keeping the warp threads close
up to the side of the reeds and therefore at a uniform distance from each other
which is important particularly when' tuft yarns have to be inserted.

Improvements in Looms for the Manufacture of Tufted 'or other
Fabrics.
We, BRINTONS LIMITED of Kidderminster in the County of Worcester, 'Carpet
Manufacturers, and THOMAS GREENWOOD of the Shrubbery Wolverley 'near
Kidderminster, aforesaid, Mechanic, 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 :-
Our invention has reference to looms for the manufacture of tufted or other
fabrics and more particularly of carpets or fabrics of the kind known Axminster,
Royal Axminster, or Moquette.
as,
According to one part of our invention we employ in looms in which grippers are
used to feed tuft yarns to the fabric: that is being, woven, an arrangement
comprising a fixed lower comb-and a movable upper comb or bar at or near the fell

page_text: of the cloth as about to be described. The tufts of yarn are laid by the grippers
upon the lower comb which is horizontal or approximately so then after the weft
has been shot the lay and reeds beat up and bind the tufts against this comb; next
the grippers open, release the tufts and rise out of the shed and in so doing
somewhat, lift up what were previously the gripped ends of the tufts. Then the
upper comb or bar with a combined upward and backward movement followed by
downward and forward movement comes behind the tufts and brings the previously
gripped ends into a vertical position in which they are then secured by another
shoot of weft the dead warp having been meanwhile raised.
Figures 1 to 7 of the accompanying drawings will serve to make this part of our
invention fully understood; they show it applied in connection with grippers which
in their form, disposition and action are the same as those described in Specification
No. 15,680 of 1890.
Figure 1 shows the parts in the positions they respectively occupy when the row
of tufts of yarn has just been laid by the grippers upon the lower comb and the
weft has been shot;
Figure 2 shows them when the lay and reeds have just beaten up the shoot of
weft and bound these tufts against the lower comb the grippers still holding one end
of each tuft;
Figure 3 when the lay and reeds have moved back and the grippers have
opened, released the tufts and partly risen out of the shed in which movement they
have somewhat lifted up what were previously the gripped ends of the tufts;
Figure 4 when the upper comb or bar has by reason of a combined upward and
backward movement come behind the tufts so as in its following movement to bring
the previously gripped ends into a vertical position and the lay and reeds are
moving forward with a shoot of weft; and
Figure 5 when the upper comb or bar by its said following movement, that is to
say a downward and forward movement has brought up the previously gripped
ends into a vertical position and they have been secured by the shoot of weft
carried forward by the lay and reeds.
Figure 6 is a plan view on a larger scale of a portion of the lower comb and
Figure 7 a section on line a- of Figure 6.
C
a represents the grippers, 6 the lay, the reeds, d the fixed lower comb and e the
upper comb or bar which has the combined upward and backward movement
followed by a downward and forward movement as and for the purpose already
explained. These movements are produced as follows:-The comb or bar e is
carried by rods (one at each side of the loom) jointed to levers or bell cranks g
which are themselves pivoted or centred at h, while to an intermediate part of the
rods are jointed rods i (one at each side of the loom). These rods are pivoted to
bell cranks also centred at h. The bell cranks and respectively bear by means
of antifriction rollers on two cams Im on a shaft n which may be either one of the
ordinary rotating shafts of the loom or a special shaft as may be found most
suitable. The forms or contours of the two cams are such as to give the herein-
.before described motions to the bar or comb e.
Another part of our invention consists of a double reed, that is to say a reed
having two dents placed one behind the other. Each warp thread passes at one
side of the back dent of the corresponding reed and then at the other side of the
front dent of the same reed, being in fact threaded through between the back and
front dents. These double reeds have the effect of keeping the warp threads close
up to the side of the reeds and therefore at a uniform distance from each other
which is important, particularly when tuft yarns have to be inserted.
The reed shown at e Figures 1 to 5 (already hereinbefore referred to) is one of
our double reeds. Figure 8 is a horizontal section on a larger scale. It will be
seen that it has two dents 1, 2 placed one behind the other. 3 represents the warp
thread which passes at the one side of the back dent, I of its corresponding reed and
then at the other side of the front dent 2 of the same reed.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a loom for the manufacture of tufted fabrics, the combination of a fixed
comb such as d upon which the tuft yarns are laid by the grippers and against
which the reeds beat up the weft and bind the tufts and of a comb or bar such as e
having a combined upward and backward movement followed by a downward and
forward movement whereby the tuft ends released by the grippers are brought up
into a vertical position, as hereinbefore described.
2. The double reed for looms herein before described.
