Improvements in or relating to Looms for the Manufacture of
Tufted or Pile 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:-
This invention has reference to looms for the manufacture of tufted or pile
fabrics of the hind known as Royal Axminster or Jacquard Axminster and its
chief object is to simplify the Jacquard mechanism and also to dispense with the
large number of levers and cords hitherto generally employed to impart the
required up and down movements from the jacquard to the yarn carriers.
The invention mainly consists in the employment of a set of strips or bars and
pegs as hereinafter described and in the combination therewith of a single feather
edged bar or lifter which will lift all the strips when required.
In carrying out the invention we employ in connection with the Jacquard
apparatus a set of strips or bars equal in number to the yarn carriers; every
such strip is formed with a number of holes the distance of which from each other
is exactly the same as that of the holes in the yarn carriers. The yarn carriers
are suspended by means of wires or cords to the corresponding strips so that
In
every lift given to a strip is equally given to the corresponding yarn carrier.
the holes of the strips are fitted pegs the heads of which project therefrom until
pushed in by the Jacquard needles under the influence of the cards on the card
cylinder or drum. The Jacquard needles pass through holes in back and front
guide plates. On the opposite side of the plates facing the ends of the pegs is
a plate which is moved at certain times as hereinafter described. Below the
vertical rows of pegs in the strips is a feather edged bar or lifter which extends
across the loom.
The operation is as follows:- The card cylinder is moved forward so as to bring
its cards in contact with the needles all of which are thereby pushed forward by
blanks or full parts of the cards except one in each vertical row, this one being.
that which corresponds with the design. The needles, except those thus selected,
come against the pegs and push the heads home against the strips, one peg in each
strip being left projecting. The card cylinder is now returned and the needles.
which it pushed forward move back to their first position under the action of springs.
The feather edged bar or lifter is then raised and in this movement it comes in
contact with the one projecting peg of every strip and thereby lifts the strip to an
extent equal to one two or more holes according to the particular peg that projects
as previously selected by the card; the corresponding yarn carriers being by the
same action lifted to the same extent. The feather edged bar and the strips will
remain lifted while the loom goes through various movements as will be well
understood after which they are allowed to return to their former position. Then
the plate on the opposite side of the strips is moved so as to come against the ends
of the pegs projecting at that side and push them back into the strip ready for the
next action of the Jacquard needles; this plate is then returned. The card
cylinder next repeats its forward movement and so on.
Instead of the hole in the card being made to select the required needle in
accordance with the design the needle may be selected by a blank or full part of

page_text: the card, in which case the selected needle will be the one pushed forward instead
of, as above described, the one not pushed. The feather edged bar must therefore
be placed at the other side of the strips, and the loom is preferably constructed so
that the bar can be fitted to and worked at either side as may be required.
The strips in their up and down movements are guided by top and bottom frames
with combs for keeping them apart; the comb teeth are preferably pointed to
enable them to enter between the strips more easily. The strips should have stop
pieces to prevent their dropping too low.
For a fine pitched carpet or fabric the jacquard can be made double, that is
to say, two Jacquard apparatus arranged as above described can be put back
to back.

COMPLETE SPECIFICATION.
Improvements in or relating to Looms. for the Manufacture of
Tufted or Pile 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 the said
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 reference to looms for the manufacture of tufted or pile
fabrics of the kind known as Royal Axminster or Jacquard Axminster, and its
chief object is to simplify the Jacquard mechanism and also to dispense with
the large number of levers and cords hitherto generally employed to impart the
required up and down movements from the jacquard to the yarn carriers.
The invention mainly consists in the employment of a set of strips or bars and
pegs as hereinafter described and in the combination there with of a single lifter or
feather-edged bar which will lift all the strips when required.
In carrying out the invention we employ in connection with the Jacquard
apparatus a set of strips or bars equal in number to the yarn carriers; every such
strip is formed with a number of holes, the distance of which from each other is
exactly the same as that of the holes from each other in the yarn carriers. The
yarn carriers are suspended by means of wires or cords to the corresponding strips
so that every lift given to a strip is equally given to the corresponding yarn
carrier. In the holes of the strips are fittted pegs the heads of which project
therefrom until pushed in by the Jacquard needles under the influence of the cards
on the card cylinder or drum. The Jacquard needles pass through holes in back
and front guide plates. On the opposite side of the plates facing the ends of the
pegs is a plate which is moved at certain times as hereinafter described. Below
the vertical rows of pegs in the strips is a feather-edged bar or lifter which extends
across the loom.
The accompanying drawings and the following further description of the
construction and operation of the loom will enable our invention to be fully
understood.
Figure 1 is an end elevation partly sectional of the Jacquard mechanism.
Figure 2 is a plan of the same with the upper frame P, upper comb Q and lower
comb R (all hereinafter described) removed.
Figure 2 is an elevation as seen from the left hand end of Figure 2.
Figure 3 is an edge view on a larger scale of one of the strips or bars detached
and without the pegs.

page_text: Figure 4 is a face view of the strip shown in Figure 3 but with the pegs in
place.
Figures 3 and 4 show a strip for holding only five pegs, while that seen in
Figure 1 is for ten pegs, but the number is optional.
Figure 5 shows in edge view another strip in which the holes are oblong instead
of round, the pegs used therewith being of corresponding shape in section.
Figure 6 is a plan of a portion of the lower comb R on a larger scale than
Figure 1.
A A are the strips or bars which are equal in number to the yarn carriers;
every such strip is formed with a number of holes a a (Figures 3 and 5) the
distance of which from each other is exactly the same as that of the holes from
each other in the yarn carriers. The yarn carriers are suspended by means of
wires or cords K to the corresponding strips A so that every lift given to a strip
is equally given to the corresponding yarn carrier. BB are pegs fitted in the
holes of the strips; the heads of these pegs project from the holes until pushed
in by Jacquard needles F F, there being one needle for every peg; in Figure 1
all the needles are shown as pushed in except one (the fourth from the top).
T is a front guide plate and S a back guide plate through which the needles FF
pass. L is a plate facing the ends of the pegs. I is a feather-edge bar or lifter
below the vertical rows of pegs and extending across the loom. D is the card
cylinder.
The operation is as follows:-The card cylinder D, which is operated by means
of the lever X, as hereinafter described, is moved forward from the position shown
in full lines in Figures 2 and 24 and in dots in Figure 1 to the position shown in
full lines in Figure 1, so as to bring its cards in contact with the needles F F
hich at this time project in front of the guide plate T as seen in Figure 2.
All the needles are thereby pushed forward by blanks or full parts of the cards
except one in each vertical row (see the fourth from the top in Figure 1) this one
being that which corresponds with the design. The needles except those thus
selected come against the pegs B and push the heads home against the strips A,
one peg in each strip being left projecting (see Figure 1). The card cylinder D
is now returned, and the needles which it pushed forward move back to their first
position under the action of the springs G, the small bosses U preventing them
from going back too far. The feather-edge bar or lifter I is then raised to the
position indicated at J, this being effected by the levers V V Figure 2, and in this
movement it comes in contact with the one projecting peg of every strip A and
thereby lifts the strip to an extent equal to one, two or more holes, according to
the particular peg that projects as previously selected by the card, the corre-
sponding yarn carriers being by the same action lifted to the same extent. The
feather-edge bar and the strips will remain lifted while the loom goes through
various movements as will be well understood, after which they are allowed to
return to their former position. Then the plate L on the opposite side of the
strips is moved by means of the levers W W (operated as hereinafter described)
to the position indicated at M so as to come against the ends of the pegs B pro-
jecting at that side and push them back into the strip ready for the next action of
the Jacquard needles; this plate is then returned. In Figure the plate Lis
shown in its back or returned position, while in Figure 2 it is seen as pressing the
pegs into line ready for the next selection by the Jacquard cards. The card
cylinder D next repeats its forward movement and so on being caused to make a
partial revolution in the usual manner and by the usual devices before each such
forward movement. Y is the lever and Z the main shaft which give motion to the
Jacquard apparatus.
The lever Y is operated by the rod Y¹ from the loom and imparts a rocking
motion to the shaft Z. On the shaft Z are keyed the two levers V V already
referred to which lift the bar I; this bar is carried by two uprights V' V₁ the
lower ends of which rest upon the levers V V and move up and down as these
levers rock with the shaft Z. The lower end of the lever X already referred to as

page_text: operating the drum D is jointed at its lower end to the lever Y and at its upper
end to an arm Y¹ keyed to the shaft Y2 to which it imparts a rocking motion; to
the shaft Yare keyed other arms Y' which as they rock give rectilinear motion
in the one direction to bars Y that move the drum D, rectilinear motion in the
other direction being given to the bars Y' by the springs Y. The levers W W
that move the plate L are carried by a sleeve W¹ on the shaft Y2 and are operated
by the rod L which is connected with the loom, and rocks the sleeve W' by means
of the arm W.
Instead of the hole in the card being made to select the required needle in
accordance with the design, the needle may be selected by a blank or full part
of the card, in which case the selected needle will be the one pushed forward
instead of as above described the one not pushed. The feather-edge bar must
therefore be placed at the other side of the strips A as indicated at N, and the
loom is preferably constructed so that the bar can be fitted to and worked at
either side as may be required.
The strips A in their up and down movements are guided by top and bottom
frames P and O with combs Q and R for keeping the strips apart; the comb
teeth are preferably pointed (see Figure 6) to enable them to enter between the
strips more easily. The strips should have stop pieces such as shown at b,
Figures 3, 4 and 5, to prevent their dropping too low. When the holes a a are
oblong as in Figure 5, and the pegs B are of corresponding shape in section, there
is a greater surface for the points of the needles F to act against; this is of
advantage because the needles cannot conveniently be put in a straight line with
the pegs.
For a fine pitched carpet or fabric the jacquard can be made double, that
is to say two Jacquard apparatus arranged as above described can be put back
to back.
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 with reference to looms for the manufacture of tufted or pile fabrics of the
kind known as Royal Axminster or Jacquard Axminster is:-
:-
1. A set of strips or bars to which the yarn carriers are connected, a set of pegs
engaging in holes in the said strips or bars, and a set of Jacquard needles for
selecting the particular pegs required by the exigencies of the design to be pro-
duced, in combination with a device for lifting all the strips by means of the
selected pegs, substantially as and for the purpose berein before described.
2. The combination with the strips or bars, pegs, Jacquard needles and lifting
device as referred to in Claim 1, of a plate for returning to their normal position
the pegs that have been pushed forward by the Jacquard needles, substantially
as hereinbefore described.
3. The improved Jacquard mechanism constructed and working substantially as
herein before described and represented in the accompanying drawings for the
purpose set forth.
