Improvements in Brake Mechanism for Warp Beams of Looms for
Weaving.
We, JAMES KIPPAX of Wrekin Villa, Lostock, Manufacturer, and Jor
ROBINSON of 46 Alexandra Road, Horwich, Mechanic, both in the County of
Lancaster, do hereby declare the nature of our said invention to be as follows:-
This invention relates to improvements in looms for weaving and consists in
This we effect
means for weighting the warp by friction or pressure on the same.
by means of a brake formed of cloth or other fibrous material extending the full
width or length of the warp beam; the said cloth or other fibrous material being
attached at each end to a metallic rod or roller; one of which is stationary and the
other rotatable. On the latter is mounted a lever to which is attached a rod with
adjustable weights, the latter being for the purpose of regulation according to the
kind or quality of cloth being woven. On the metallic rod is mounted a ratchet wheel
in which gears a
pawl" secured to the framework of the loom; the said "pawl
being for the purpose of preventing a reverse action of the ratchet wheel as the
warp decreases in diameter.

ROBINSON of 46 Alexandra Road, Horwich, Mechanic, both in the County of
Lancaster, do hereby declare the nature of our said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-

same,
In all the figures the same letters are employed to indicate corresponding parts.
A, A are the loom sides, and B the warp beam. The metallic rod or crossbar C
is attached in any convenient manner to the side frames A of the loom. In the
bearings D on each side of the loom is mounted the rotatable roller E on which
the brake cloth F is mounted or wound to allow of the decreasing diameter of the
warp G as the latter is delivered in the operation of weaving. On the end of the
roller or shaft E is loosely mounted the lever I to which is attached the rod J with
the adjustable weights K, the latter being for the purpose of regulating the tension
on the brake cloth F according to the kind or quality of cloth being woven.
the metallic rod or roller E is mounted the ratchet wheel L in which gears the
"pawl" M secured to the lever I by the pin N. The "pawl" M gearing with the
ratchet wheel L is provided for the purpose of preventing the brake cloth becoming
unwound whereby a uniform tension is imparted to the brake cloth F. The lever I
is raised when required-by a cord, chain, or other equivalents, or by hand as
required or desired.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
In looms for weaving the use, construction, and arrangement of mechanism
composing our improved brake for regulating the tension of the warp beam,
substantially as described and as illustrated in the annexed drawings.
Dated the 10th day of February 1896.
