PROVISIONAL SPECIFICATION:
Improvements in Looms for Weaving Royal' Axminster or Moquette
Tufted Fabrics.
I, WILLIAM ADAM of the firm of Tomkinson and Adam of Kidderminster in the
County of Worcester, Carpet Manufacturer do. hereby declare the nature of this
invention to be as follows:-
The invention relates to looms for weaving Royal Axminster or Moquette Tufted
Fabrics, and consists in the employment of additional means for the purpose of more
securely raising the tufts to the surface of the fabric and preventing their falling to
the back thereof.
Heretofore a single comb has been employed to raise the ends or tufts of yarn
through the spaces in the warp, and such comb is made to work so as to push the
tufts through the spaces between the warp, but it is found that, if the tufts of
yarn do not hang or lie straight from the tubes through which the tufting yarns
pass, the comb will miss the tufts and consequently they fall to the back of the carpet
and thereby produce imperfect work; the object of my invention is to remedy
this defect and cause the comb to raise all the tufts of yarn to the surface of the
fabric.
For this purpose I propose to employ a second comb, or thin strip of steel, or
iron blade, to work close to the front of the present comb, to push forward and
straighten the tufts of yarn projecting from the tubes, prevent their falling through
the spaces in the old comb, and place them in position opposite the spaces in the
warp ready for the present comb to push them through to the surface; when my
additional comb, bar, or blade has done this work, it is caused to drop downward and
leave the present comb to do its work.

Improvements in Looms for Weaving Royal Axminster or Moquette
Tufted Fabrics.
I, WILLIAM ADAM of the firm of Tomkinson and Adam, of Kidderminster, in the
County of Worcester, 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 :-
The invention relates to Looms for weaving Royal Axminster or Moquette tufted
fabrics of the character shown and described in the specification of Letters Patent
granted to Sydney Pitt, dated January 18, 1877, No. 235, and consists in the employ-
ment of additional means for the purpose of more securely raising the tufts to the
surface of the fabric, and preventing their falling to the back thereof.
Heretofore a single comb has been employed to raise the ends or tufts of yarn
through the spaces in the warp, and such comb is made to work so as to push the
tufts through the spaces between the warp; but it is found that if the tufts of yarn
do not hang or lie straight from the tubes through which the tufting yarns pass,
the comb will miss the tufts, and consequently they fall to the back of the carpet
and thereby produce imperfect work; the object of my invention is to remedy this
defect and cause the comb to raise all the tufts of yarn to the surface of the fabric.
. For this purpose I propose to employ a second comb or thin strip of steel or iron

page_text: blade, to work close to the front of the present comb, to push forward and straighten
the tufts of yarn projecting from the tubes, prevent their falling through the spaces
in the old comb, and place them in position opposite the spaces in the warp, ready for
the present comb to push them through to the surface; when my additional comb,
bar, or blade has done this work, it is held down by the warp, and, if desired, by
a fixed wire or chain, which prevents the additional comb from rising beyond its
proper height, and leaves the present comb to do its work.
And in order that my said invention may be more clearly understood and readily
carried into effect, I will proceed, aided by the accompanying drawings, more fully to
describe the same.
DESCRIPTION OF THE DRAWINGS.
Figures 1 and 2 are sections of parts representing my invention applied to a loom
such as that described in the before mentioned specification, the old parts of which are
marked with the same letters of reference as those employed therein; in figure 1 the
comb and supplemental bar, plate or comb, are shown in their most forward position,
and in figure 2 they are represented as in their most backward position. Figure 3 is
a cross section, Figure 4 an elevation, and Figure 5 is an underside view of
the old comb and of the supplemental bar, plate, or comb, drawn full size.
M is the reciprocating comb shown and described in the aforesaid specification, and
which receives similar motions to that therein described.
The comb M is formed, as heretofore, with teeth (1), between which are spaces (2),
to allow the teeth (1) to rise between the warp threads, which latter at such times
pass into the spaces (2).
To the comb M is connected by the springs (3) (3), a supplemental bar, plate,
or comb (4), the teeth (5) of which stand a little in advance of the teeth (1) of the
comb M, and in the rearward motion of such parts, the supplemental bar, plate, or
comb will act to push forward and straighten the tufts of yarn projecting from
the tubes, prevent their falling through the spaces (2) in the comb M, and place
them in position opposite the spaces between the warp threads, ready for the comb M
to push them through to the surface; this is effectually secured in the following
manner; it will be noticed that the teeth (5) of the supplemental comb (4) are
opposite the spaces (2) of the comb M, they will therefore act to space the tufts
and arrange them in line with the hollows between the teeth (5) of said comb (4),
and as the said supplemental comb (4) precedes the comb M, the said supplemental
comb will straighten the tufts and lay them in line to be pushed up through the
spaces between the warp threads by the teeth of the comb M. The supplemental
comb (4), when it has done its work, is held down by the warp threads, or if
desired by a fixed wire or chain represented by the dotted line (6), which prevents
it from rising beyond the proper height, whilst the comb M continues its motion
and the teeth thereof rise up through the spaces in the warp and carry the tufts
up with them.
It will be observed that the comb M, as also the supplemental comb (4), when in
their most forward position, stand just underneath the rear end of the guard plate M°,
instead of the comb M, as heretofore, being stopped in its forward motion by the rear
edge of such guard plate M.
I would here remark that a plain bar or plate might be substituted for the supple-
mental comb (4), but although such would to some extent assist to straighten the
tufts for the subsequent action thereon of the comb M, it would not be so efficient
as the toothed edge bar, plate, or supplemental comb (4) berein shown and described.
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 :-
In looms for weaving tufted fabrics, the combination with the comb for lifting or
pushing the tufts through the spaces in the warp, of a bar, plate, or supplemental

page_text: comb, preceding the before mentioned comb, and acting to straighten the tufts to
ensure their being lifted or pushed through their proper spaces in the warp, sub-
stantially as herein shown and described.
