Improvements in the Manufacture of Tufted Pile Carpets, and other
Tufted Pile Fabrics, and in Apparatus. therefor.
I, HENRY DIXON, Managing Director of Henry Jecks Dixon & Sons, Limited,
Carpet Manufacturers, of Kidderminster, in the County of Worcester, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in weaving that class of carpets and other
fabrics in which the pattern is first set up on bobbins, and the bobbins then placed
into an endless chain on the loom in rotation numbers for weaving into cloth,
whereby I am enabled to produce a bordered carpet without changing the set of
bobbins. For this purpose I employ two sets of bobbins placed in the same chain
as hereinafter more particularly described, instead of one set as hitherto.
In order that my improvements may be clearly understood I will first describe
the method now employed for manufacturing tufted pile fabrics. The bobbins are
placed in the endless chain of the loom by rotation link by link and each bobbin is
moved forward one link, after having been taken out of the chain passed through
the warp and placed back into the chain.
I retain the general arrangement above described but according to my invention
I place one set of bobbins in each alternate link by rotation and place the other set
in each intervening alternate link by rotation; and then I move each bobbin
forward two links after it has been taken out of the chain passed through the warp
and placed again into the chain; by this means I weave as much as I require from
the one set of bobbins, and I move the chain one link forward and I then weave in
like manner the other set of bobbins. By this arrangement I can weave a border
to a carpet without a seam and without taking out one set of bobbins and putting
in a fresh set of bobbins as has hitherto been necessary.
The cam and lever on the main shaft of the loom and the ratch-rod attached to
the lever are arranged to give the required movement to the chain, and in place of
the usual quadrant I advantageously use a toothed segment.

Improvements in the Manufacture of Tufted Pile Carpets and other
Tufted Pile Fabrics, and in Apparatus therefor.
1, HENRY DIXON, Managing Director of Henry Jecks Dixon & Sons, Limited,
Carpet Manufacturers, of Kidderminster, in the County of Worcester, 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 relates to improvements in weaving that class of carpets and other
fabrics of which the pattern is first set up on bobbins, and the bobbins then placed
into an endless chain on the loom in rotation numbers for weaving into cloth,
whereby I am enabled to produce a bordered carpet without changing the set of
bobbins. For this purpose I employ two sets of bobbins placed in the same chain
as hereinafter more particularly described, instead of one set as hitherto.
In order that my improvements may be clearly understood I will first describe
the method now employed for manufacturing tufted pile fabrics. The bobbins are
D

page_text: placed in the endless chain of the loom by rotation link by link, and each bobbin is
moved forward one link after having been taken out of the chain, passed through
the warp, and placed back into the chain.
I retain the general arrangement above described, but according to my invention
I place one set of bobbins in each alternate link by rotation and place the other set
in each intervening alternate link by rotation, so that one set is in position for
work and the other set is idle.
I move the chain forward two links after each bobbin has been taken out of the
chain, passed through the warp and placed again into the chain, by which means I
weave as I require from the one set of bobbins and I then move the chain one link
forward or backward and weave in like manner from the other set of bobbins.
The cam on the main shaft of the loom and lever actuated thereby, the ratch-rod
attached to the lever and the toothed segment gearing with the ratch-rod are
arranged to give the required movement to the chain.
To enable my invention to be fully understood I will describe how it can be
.carried into practice by reference to the accompanying drawing, in which :-
Figure is a side elevation of a loom adapted for the manufacture of tufted pile
carpets and other tufted pile fabrics according to my invention:
Figure 2 is a view of a portion of the side of the loom opposite to that shewn in
Figure 1:
Figure 3 is a detached view of a handle hereinafter described for putting the sets
of bobbins into and out of operation.
a, a and b, b, are the two sets of bobbins which are arranged in the usual chain o
so as to alternate with one another as shewn.
is the cam on the main-shaft e of the loom, and f is the lever actuated by the
said cam; g is the ratch-rod attached to the lever f, and h the toothed segment
gearing with the ratch-rod.
The toothed segment is loose on the chain-shaft and is moved from left to
right when the ratch-rod g is raised and from right to left when the ratch-rod is
lowered; and the spring pawl * engages with the ratchet wheel i which is fixed on
the chain-shaft i¹. The said pawl is carried by a bracket fixed to the toothed
segment. The said ratch-rod and toothed segment serve by these means in com-
bination with the cam d to impart, through the ratchet-wheel i, the movement to
the chain-shaft ¹ necessary to present alternate bobbins to the arms j which remove
them from the chain c and pass them through the warp.
In order to move the chain c the distance of one link or one bobbin so as to put
the idle set of bobbins into operation, I mount a toothed disc k on one end of the
shaft, and I provide a lever-handle 1, Figures 2 and 3, adapted to bear against
any tooth of the disc k, so that the disc k and consequently the shaft can be
rotated to the required extent. The lever-handle is so formed at one end as to
partly embrace and bear against the boss of the disc k which forms a fulcrum for it.
The chain c having been adjusted to present the required set of bobbins, those
marked a for example, to the arms; and the loom being then set in motion, after
each bobbin has been removed therefrom and passed through the warp by the said
arms, the chain is moved two links forward and so on until as much as is required
has been woven from the bobbins a. The operative then applies the lever-handle !
to the toothed disc k and by means thereof moves the chain c forward or backward
to the extent of one link so as to bring the other set of bobbins 6 into action and
the weaving is continued from this set.
By this arrangement I can weave a border to a carpet without a seam and
without taking out one set of bobbins and putting in a fresh set of bobbins as has
hitherto been necessary.
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. In a loom for manufacturing tufted pile-fabrics of that class in which the

page_text: pattern is first set up on bobbins, and the bobbins then placed in an endless chain
in rotation numbers as set forth, the described method consisting in working two
sets of bobbins arranged in the endless chain in the manner described, and first
weaving as much of the fabric as is required for one set of bobbins, next moving
forward two links after each bobbin has been taken out of the chain, passed through
the warp and placed again into the chain, then moving the chain forward or
backward one link, and effecting the weaving in like manner with the other set
of bobbins, substantially as described.
2. In a loom for weaving tufted pile carpets or fabrics the combination of cam d,
lever f, ratch-rod g, arms ; and toothed segment h, constructed as described and
serving to take from a chain and to present alternate bobbins to the arms g, such
bobbins being arranged on the chain c, in the manner described, substantially as set
forth.
3. The combination with the chain c, cam d, lever f, ratch-rod 9 and toothed
segment h, of the disck and lever handle 1, said disc being adapted to be operated
by the lever handle bearing against any of its teeth to turn the disc and its shaft
for moving the chain the required distance to bring the idle set of bobbins into
operation, substantially as set forth.
4. The improved loom for weaving tufted pile carpets and other tufted pile
fabrics hereinbefore described and illustrated in the accompanying drawing.
