Improvements in Looms for the Manufacture of Pile Carpets in
Imitation of Oriental Carpets.

MOULLEC, ANDRÉ CHARLES HENRY SALLANDROUZE, and LOUIS PAUL SALLANDROUZE
LE MOULLEC, all of 23 Boulevard de Strasbourg, Paris, France, Carpet Manufacturers,
do hereby declare the nature of this invention to be as follows :--
This invention relates to a construction of loom for the manufacture of pile
carpets, imitation Oriental carpets for which Letters Patent No. 3175 of 1888 have
been obtained.
The present improvements relate to mechanism for cutting the threads and for
determining the distance which the tubes carrying the pile material pass through
the warp.
The apparatus for cutting consists of two bars carrying knives one set of which
has a reciprocating motion over the other and which act in a similar manner to the
cutters of horse clippers. The lower bar is fixed while the upper one receives
reciprocating motion by means of levers at each end, having teeth entering recesses
in the bar, and connected together by a rod, the one lever being actuated by a bell
crank lever worked by the loom.
The cutting is effected as follows:
The tubes with the pile material having been inserted through the warp, and the
first tuft having been nipped by the comb, the above described cutting apparatus
which is carried by two pivotted arms, is lowered into such a position that each
woollen thread is situated in one of the spaces between the teeth; the levers of the
apparatus are then actuated so as to impart motion to the upper blades to the extent
of one space, by which means each thread is cut through; the knife bar then moves
back and the arms carry the apparatus back to its original position.
For effecting the insertion of the tubes carrying the pile threads into the warp, a
number of rows of reels having the pile threads wound upon them and connected to
a row of tubes through which the ends of the pile threads are passed, are held by
spring catches in a raised position and are brought by the Jaquard apparatus opposite
two nipping instruments one on each side of the loom.
These nipping instruments are on the ends of short spindles, carried by two arms
working on pivots on the loomi frame and actuated by à cam on the loom shaft, so
that these arms at the required moment cause the nipping instruments to seize the
row of reels and tubes and draw the same down between vertical guides until they
arrive near the warp, when fingers on the nipper spindles come in contact with stops
whereby the spindles are turned so as to bring the tubes parallel with the warp.
At the required moment the stops are withdrawn, liberating the nippers, and the
tubes then drop into a vertical position between the warp threads.
After the threads have been seized as described in the Specification to the said
previous Patent, and cut, the before mentioned arms carry the nippers and with them
the reels and tubes up into their original position where they are held by the spring
catches.

Improvements in Looms for the Manufacture of Pile Carpets in
Imitation of Oriental Carpets.
We, THEOPHILE SALLANDROUZE, BENJAMIN LEONCE CHARLES SALLANDROUZE LE
MOULLEC, ANDRÉ CHARLES HENRY SALLANDROUZE, and LOUIS PAUL SALLANDROUZE
LE MOULLEC, all of 23 Boulevard de Strasbourg, Paris, France, Carpet Manufacturers,
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 a construction of loom for the manufacture of pile
carpets in imitation of oriental carpets for which Letters Patent No. 3175 of 1888
has been obtained.
The present improvements relate to mechanism for cutting the threads and for
determining the distance which the tubes carrying the pile material pass through the
warp.
The apparatus for cutting is shewn in front view at Fig. 1 of the accompanying
drawings, in plan at Fig. 2 and in cross section at Fig. 3.
It consists of two blades 9 and h situated one above the other and provided with
cutters similar in arrangement to the cutters of horse clippers, the lower blade h
being fixed while the upper one g is connected by a screw i to a bar which is
moved longitudinally to and fro by levers l'connected to the rod m.
The axes of the two levers carry a tooth n which engages in a corresponding
hollow of the bar k and the axis of the lever l¹ is actuated by an elbow lever which
is worked by the loom.
The cutting of the pile threads is effected as follows.
The tubes having been inserted through the warp, and the first tuft having been
nipped by the comb, as described in the said former Patent, the apparatus P which
rests on two arms turning on an axis not shewn on the drawing, moves downwards
so that each thread of wool is situated in the spaces (Fig. 2) hetween two cutters r r.
At this moment the rod m moves from left to right, causing the upper plate g to
slide on the lower plate h to the extent of one tooth whereby each thread will be cut.
The reverse movement brings the upper plate back to its original position again,
and the arms supporting P bring this also back to its position of rest.
The mechanisin which produces the insertion of the tubes carrying the pile threads
into the warp is arranged as shewn at Figs. 4 and 5, which are respectively a part
side view and part front view of the loom. Figs. 6 and 7 shew enlarged details,
Fig. 6 shewing a side view of the arrangement of thread reels and tubes, and
Fig. 7 shewing a front view of the mechanism for actuating the nippers or catches.
The tubes T Fig. 5 are seized by the two nippers p p which is pressing upon the
spring catches r effect the detachment of the apparatus consisting of the reels R
carrying the wool and the thread tubes T; the two arms a a, one on each side of the
loom which carry the nippers p p and the parts R and T, being actuated at the
required moment by suitable cams below, cause the above named parts to descend,
and on arriving at the stop 6 the pin c on the arm of the axis e of the nippers
in engaging with the stop, causes the axis e to turn partially, thereby bringing
the tubes into a more or less horizontal position, almost parallel with the warp
threads.
The stop b, being then moved by its lever and cam, passes out of contact with the
pin c, and the tubes T being now free to descend by gravity, turn into a vertical
position, and thereby penetrate between the warp threads.
After the threads have been seized as described in the Specification to the said
previous Patent and cut as above described, the arms a carry the nippers p and with
them the reels R and tubes T up again into their original position, where they are
held by the spring catches.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed we declare that what we claim is :-
In looms of the kind herein referred to, the herein described mechanism for
cutting the pile threads and for effecting the penetration of the thread tubes into the
warp.
