I, JOHN CLAYTON MEWBURN of 169 Fleet Street in the City of London, Fellow
of the Institute of Patent Agents do hereby declare the nature of my invention for
IMPROVEMENTS IN WEAVING CARPETS AND OTHER LIKE FABRICS AND IN THE
LOOMS EMPLOYED THEREIN to be as follows:-
This invention has reference to the manufacture of pile fabrics in which two
pieces of fabric are woven face to face at one operation, such pieces being connected
together in the manufacture by means of the pile threads, upon the severing of
which two distinct pieces of pile fabric are produced. The processes hitherto
adopted for weaving fabrics in this manner do not permit of making long or high
piles (hautes laines) and are therefore not applicable to the weaving of carpets.
Now the object of this invention is to weave fabrics with long or high pile such as
Wilton or Brussels carpets, plushes, imitation furs and the like. This result is
mainly attained by a special form of reed.

tion The two dents between which the foundation warps pass are united near the
middle at S. This union extends to a greater or less length according to the
distance it is desired to leave between the two fabrics, this distance being double
the height of the pile. The yarn 3 (foundation warp of the upper piece) passes

page_text: above the union S and the yarn 4 (foundation warp of the under piece) passes
under this union. It follows that when the warp 4 is raised the reed itself is
raised; the batten is specially constructed to allow of this displacement of the
reed.
In order to have perfect selvages it is well to weave with two shuttles, each
shuttle having three consecutive throws for a two-shoot carpet and two consecutive
throws for a single-shoot carpet. Each shuttle thus belongs to one piece or fabric,
the one to the upper and the other to the under; the selvages are then as good as
in ordinary weaving-In case of need one can weave with only one shuttle, but
then the selvages would be cut like the pile and this for some carpets would be
objectionable. Jacquard mechanism can be applied to the improved loom as to
other looms.

I JOHN CLAYTON MEWBURN, of 169 Fleet Street, in the City of London, Fellow
of the Institute of Patent Agents do hereby declare the nature of this invention
(a communication from abroad by Frédéric Grandel of Ascq, Nord, France, Manufac-
turer) 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 the manufacture of pile fabrics in which two
pieces of fabric are woven face to face at one operation such pieces being connected
together in the manufacture by means of the pile threads, upon the severing of
which two distinct pieces of pile fabric are produced. The processes hitherto
adopted for weaving fabrics in this manner do not permit of making long or high
piles (hautes laines) and are therefore not applicable to the weaving of carpets.
Now the object of this invention is to weave fabrics with long or high pile such as
Wilton or Brussels carpets, plushes, imitation furs and the like. This result is
mainly attained by a special form of reed.
Figure 1 of the annexed drawings represents a side view (in part) of the loom
employed for the purpose of this invention. G is the pile warp. H the binding
warp of the upper piece or fabric. I the binding warp of the under piece. K the
warp for the backs or foundations of the two pieces. F the yarn carrier or guide.
E and D the crossing points. C the healds. B the reed. A, A the drawing rollers.
V the double fabric severed into two pieces V₁ and V. Figure 3 represents the
draft. Figure 4 is a transverse section showing the crossing of the five warps and
the weft. Figure 2 represents the reed which is the important part of the inven-
tion. The two dents between which the foundation warps pass are united near the
middle at S. This union extends to a greater or less length according to the
distance it is desired to leave between the two fabrics, this distance being double
the height of the pile. The yarn 3 (foundation warp of the upper piece) passes
above the union S and the yarn 4 (foundation warp of the under piece) passes
under this union. It follows that when the warp 4 is raised the reed itself is
raised; the batten is specially constructed to allow of this displacement of the
reed.
In order to have perfect selvages it is well to weave with two shuttles, each
shuttle having three consecutive throws for a two shoot carpet and two consecutive
throws for a single shoot carpet. Each shuttle thus belongs to one piece or fabric,
the one to the upper and the other to the under; the selvages are then as good as
in ordinary weaving. In case of need one can weave with only one shuttle but
then the selvages would be cut like the pile and this for some carpets would be
objectionable. Jacquard mechanism can be applied to the improved loom as to
other looms.

page_text: Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, as communicated
to me, I declare that what I claim is :-
1. The weaving of carpets and other like fabrics with long or high pile in the
manner herein before described.
2. The construction of looms as herein before described for the purpose of weaving
carpets and other like fabrics with long or high pile in the manner set forth.
