WC, THEOPHILE SALLANDROUZE, CHARLES SALLANDROUZE, and HENRY SALLAN-
DROUZE all of the firm of Sallandrouze Brothers of Aubisson in the Republic of
France Carpet Manufacturers, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved carpet resembling oriental carpet in texture
and quality.
The improved carpet is made as follows Referring to the accompanying drawing
which shows in section the manner in which the threads are arranged in two forms
of the improved carpet.
The carpet consists of two webs each formed of a warp and weft of flax, namely the
lower web with warp 1. 1 and weft 2. 2 and upper web with warp 3. 3 and weft 4. 4.
The wool is inserted in the shape of tufts 6-under one lower warp over an upper
warp and under the next lower warp. The ends of each tuft terminate above the
carpet and form the pile.
By this construction the carpet consists essentially of two superposed webs united
together by the tufts of wool. The thread 5 (Fig. 2) may be introduced between the
two webs and will give a more substantial thickness to the carpet if required.

Improvements in Carpets.
We, THEOPHILE SALLANDROUZE, CHARLES SALLANDROUZE, and HENRY SALLAN-
DROUZE, all of the firm of Sallandrouze Brothers, of Aubusson, in the Republic of
France, Carpet Manufacturers, do hereby declare the nature of our 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 consists in an improved carpet resembling in texture oriental carpet.
It consists essentially of two superposed webs each composed of a warp and weft and
locking between them in a peculiar manner and connected together by tufts of wool,
the projecting ends of which form the pile of the carpet.
Referring to the accompanying drawing:
Fig. 1 illustrates in cross section the manner in which the threads are arranged in
the carpet.
Fig. 2 illustrates in a similar manner a modified form of the carpet.
Fig. 3 is an end view and Fig. 4 a perspective of the cylinder on which the worsted
is wound for the cutting of tufts of equal length.
Fig. 5 a diagram illustrating the manner of operating the heddles.
Fig. 6 a diagram illustrating the mode of introducing the tufts.
Fig. 7 shows the pattern card for the guidance of the weaver-each square
representing a tuft of wool.
The yarn of which the pile is to be composed is wound a suitable number of times
according to the thickness of the tuft around the cylinder a, which has a diameter
corresponding to the length of the pile. The knife d is then passed along the
channel 6 by which means the coils of the yarn are cut and a tuft C is produced.
The loom for the manufacturer of the carpet is provided with two rollers one for each
set of warp threads, and four heddles operated by six treadles in the manner set forth,
the object being first to bring the warp threads into position to form a shed for the
tuft; secondly to return the warp threads and so actuate them thereafter as to form
sheds for the successive reception of four wefts, namely two alternate wefts for each
web and lastly to form a shed for the passage of a stout intermediate weft which may
be omitted if desired but which gives greater thickness and substance to the carpet.
Referring to Fig. 5 e¹ e² e e e e are the treadles, ffff represent the heddles
gggg are warps, g3 g being two warps of the upper web, g¹ g² warps of the lower
web 2. 4. alternate wefts of lower web-1. 3 alternate wefts of upper web-5. inter-
mediate stout weft preferably of wool.

Ou depressing the first treadle e¹, the warps g¹ g² are raised and the warps g³ g
relatively depressed. The weaver now takes a tuft of wool of the colour corresponding
to that shown by the relative square of the pattern card, and passes the said tuft
horizontally across under the warps g g and over the warp g³ as illustrated in Fig. 6;
when a whole row of tufts have been inserted in this manner, the second treadle e² is
depressed, this raises the warp g³. The weft 1 is now thrown through the shed so

page_text: formed. The third treadle e³ is now depressed which raises the warps g¹ g³ g¹ and
weft 2 is thrown. The fourth treadle e then raises the warp g' and weft 3 is thrown,
the fifth treadle e raises the warps g² y g' and weft 4 is thrown. If a carpet without
weft 5 is to be woven (Fig. 2) the first treadle e' is now depressed and a new row of
tufts put in and the above described process is repeated; if however the weft 5 is
to be inserted (Fig. 1) the sixth treadle e is depressed, this raises warps gª gª and
forms the shed for the reception of weft 5. Treadle e¹ is now depressed, a new row
of tufts inserted and the process repeated.
:-
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we claim is :-
1. As a new product of manufacture the carpet consisting of two webs each having
a warp and weft, and connected together by tufts forming the pile substantially as
set forth.
2. As a new product of manufacture the carpet consisting of two webs connected
together by tufts forming the pile, with a weft 5 thrown between the said webs
substantially as set forth.
3. The process of weaving such carpet substantially as set forth.
