LOOMS FOR WEAVING."
"IMPROVEMENTS IN
The first part of my Invention relates to the weight motion, and consists of
certain improvements in looms for weaving cotton and woollen fabrics, etcetera, and is
intended more particularly to dispense entirely with weights and levers as now
almost universally used. Instead of the tension on the warp being obtained by
means of weights and levers, my Invention performs the same duty by means of two
coiled steel springs attached to the weight rope (by a "grip," also my improvement
to be hereafter described). The tension is regulated by means of a worm and toothed
wheel fixed on one end of a horizontal bar or shaft, actuated when necessary by a
hand wheel fixed on the opposite end of a small shaft the worm is on. The uniform
tension put upon the yarn by these springs while the shedding is going on renders
the yarn less liable to break, charks or cracks are almost impossible, a better cover
is obtained, much less wear and tear of the healds and other working parts of the
loom than when subjected to the continual jerks and strains of weights and levers
as usually applied.
More particularly my Invention consists of a horizontal bar or shaft running
across or from side to side of the loom, and is for convenience placed under the yarn
beam;
this bar or shaft having journals at each end, is capable of revolving at
pleasure, the yarn being kept in tension by means of a toothed wheel and worm
tightened and liberated when necessary by a hand wheel. Brackets are securely
fixed, one to each side of the loom, in which the journals of the horizontal shaft are
allowed to work. One of such brackets is so constructed as to carry a short shaft,
to which is attached the worm and hand wheel, the worm gearing in the toothed
wheel fixed on the end of the horizontal shaft; when necessary to regulate the
tension on the yarn the hand wheel is turned and reversed accordingly. Two bosses
are fixed on the horizontal shaft, one at each end, on which the steel springs are
coiled, and to which one end of the steel coiled spring is secured; to the other or
outer end of the steel springs are attached the weight ropes for giving the requisite
tension to the yarn.
The second part of my Invention consists of an improved weight rope attachment,
called a "grip," intended for the purpose of securing firmly one end of the weight
rope or chain, thereby dispensing with the necessity for "knotting" or tying such

page_text: weight rope as is usually done, thus economising expenses in ropes, etc., and
saving much trouble and labor and annoyance in knotting and unknotting
the same.
More particularly my improvement in the weight rope attachment or "grip” is
constructed as follows:-
One end of a forked or knuckle joint is made in a special way, the other part
being formed in the usual manner, but in my case a tongue is allowed to extend
beyond the jointed part of the knuckle and overlap the shoulder of the forked part
of the joint for the purpose of forming the "grip"; the forked end of the joint is
attached to the outer end of the spring, the other or tongued part forming a kind of
lever and fulcrum (the joint being the fulcrum); the tension on the yarn causes the
weight rope to impinge on the longer end of the lever, and binds firmly the end
of the weight rope between the jaws of the "grip"; consequently the greater the
tension on the yarn the more firmly will the "grip" bind the rope.
