PROVISIONAL SPECIFICATION.
Improvements in Loose Reed Looms for Weaving.
:
We, JOHN HALL, and ROBERT HALL, of the firm of Robert Hall and Sons, of
Hope Foundry, Bury, in the County of Lancaster, Textile Machinists, and JOHN
HOWARD HALL, of Hope Foundry aforesaid, Manager, do hereby declare the
nature of this invention to be as follows:-
Our invention relates to loose reed looms and the object of our improvements is
to improve the locking motion of the reed.
In the ordinary locking motion a bowl acts upon a curved spring secured at one
or each side of the loom for locking the reed on the backward stroke of the lathe ;
these springs are liable to break and also to shake loose where bolted to the loom
side.
To obviate these defects wo substitute for the curved spring a bracket on which
a metal plate is pivoted, acting on the underside of the plate is a stud which passes
through two projections cast with the bracket; a spiral spring is confined between
these two projections on the bracket in such manner that the spring along with the
stud holds the plate normally up and a stop piece on the plate acting on a stop
piece on the bracket prevents it from being raised too high.
When the lathe moves back the bowls on one or each side of the lathe come over
and depress the plate or plates and the pressure of the springs on their lower sides
acting through the bowls which are carried as usual by arms secured to the shaft
of the reed holder maintain the latter and the reed in their proper positions.

COMPLETE SPECIFICATION.
Improvements in Loose Reed Looms for Weaving.
We, JOHN HALL and ROBERT HALL, of the firm of Robert Hall and Sons,
of Hope Foundry, Bury, in the County of Lancaster, Textile Machinists, and
JOHN HOWARD HALL, of Hope Foundry aforesaid, Manager, 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 :-
Our invention relates to loose reed looms and the object of our improvements is
to improve the locking motion of the reed.
In the ordinary locking motion a bowl acts upon a curved spring secured at one
or each side of the loom for locking the reed on the backward stroke of the lathe ;
these springs are liable to break and also to shake loose where bolted to the loom.
side.
To obviate these defects we substitute for the curved spring a bracket on which
a metal plate is pivoted, acting on the under side of the plate is a stud which passes
through two projections cast with the bracket; a spiral spring is confined between
these two projections on the bracket in such manner that the spring along with
the stud holds the plate normally up and a stop piece on the plate acting on a stop
piece on the bracket prevents it from being raised too high.
And in order that our invention may be fully understood and readily carried
into effect we will describe the accompanying sheet of drawings reference being
had to the figures and letters marked thereon.

page_text: Figure 1 is a side elevation and Fig. 2 a plan of our improved locking motion
for a loose reed loom.
In these views, a designates part of the side framing of the loom, b one of the
lathe swords and c a connecting rod by which it is actuated from the crank shaft,
-d the lathe, e the loose reed, the lathe or reed cap, g the reed holder and the
centre shaft on which the reed holder is mounted. On the shaft h are also fixed
the locking finger j the knocking off finger k and the arm / which carries a bowl m.
All the foregoing parts are of the ordinary construction and operate in the usual
way.
The parts embodying our improvements consist of the metal plate
n which is
pivoted at o to the bracket p which is bolted adjustably to the side framing a and
on which are cast two snugs or projections pl p*.
Through the projections p₁is passed a study on which is the spiral spring &
one end of which bears on the projection p' and the other against a shoulder'
formed by an enlarged portion of the stud q. so that the stud is supported by the
spring. The under side of the platen bears on and is supported by the top of
the stud 9 and a stop piece n' on the plate n coming against a stop piece p² on the
.bracket p prevents the front inclined portion of the plate being raised too high.
When the lathe moves back the bowl m (or bowls m if one be employed on each
side of the loom) comes upon the incline and so depresses the plate n (or plates as
the case may be) and compresses the springs and the pressure or resistance of the
spring acting through the bowl m arm land shaft h locks and maintains the reed
holder g and reed e in their proper positions, until the bowl m again leaves the
plate n.
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 a loose reed locking motion the arrangement use and application in combina-
tion with the arm land bowl m, of an inclined metal plate such as n, pivoted to an
adjustable bracket and supported by a spring substantially in the manner and for
the purpose herein set forth.
