I HENRY GARDNER of 166 Fleet Street, London, Patent Agent, do hereby
declare the nature of the said invention for IMPROVED MEANS AND APPLIANCE
FOR ENSURING UNIFORM TENSION OF WARP THREADS OF LOOMS
"
A communication
to me from abroad by Leon Fleurot and Emile Vial both of Val D'Ajol, (Vosges),
France, Weavers to be as follows:-
The object of this invention is to affix steel springs to the two extremities of an
iron rod which rod is supported at each end by the frame of the loom.
The thread bearer or rod pressed on by the warp threads and gives to the thread
a much more regular tension according to its feeding motion, it softens the blow of
the batten of the loom and prevents by that, any shock to the weavers beam;
consequently the breaking of warp threads is sensibly diminished. It avoids
entirely inequalities "robands" and "feints" in weaving and produces a very
fine grain and a very regular texture. By the use of this invention one may
considerably diminish the pression weights of the weavers beams and thus prevent
undue wear of the harness and pression cords.
On account of the elasticity and smoothness it imparts, articles of the thinnest
weft yarns may be woven without the least irregularity.

I HENRY GARDNER of 166 Fleet Street, London, Patent Agent, 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 object of this invention is to affix steel-springs to the two extremities of an
iron rod which rod is supported at each end by the frame of the loom.
The thread-bearer or rod is pressed on by the warp threads and gives to the
thread a much more regular tension according to its feeding motion; it softens the
blow of the batten of the loom and prevents by that any shock to the weavers-
beam, consequently the breaking of warp-threads is sensibly diminished. It
entirely avoids inequalities, robands and feints in weaving and produces a very
fine grain and a very regular texture.
By the use of this invention one may considerably diminish the pression
weights of the weavers-beams and thus prevent undue wear of the harness and
pression-cords.
On account of the elasticity and smootliness it imparts, articles of the thinnest
weft-yarns may be woven without the least irregularity.
Figure 1 of the annexed drawings shows at A the axis of the thread-bearer, B is
the movable roller of the same. Č C are the steel springs worked by the pass of
the harness and imparting the regular tension to the warp threads. DD are the
fulcrums of the springs. E E the fulcrums of the movable rollers of the thread-
bearer.
Figure 2 is a separate view of the thread-bearer in which D D are the fulcrums
of the springs and C C the steel springs.
Figure 3 shows the frame of a loom to which the thread-bearer is applied. B is
the roller. D the fulcrum and C the spring.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
First. The improved means and appliance for ensuring uniform tension of warp
threads of looms hereinbefore described.
Secondly. In a weaver's loom, the employment of springs in connection with a
movable thread bearer substantially as described and shown in the annexed
drawings.
