Improvements in Loose Reed Looms.
SAM WEBSTER, Loom Overlooker, Morley, Yorkshire, and WILLIAM WEBSTER
AUSTIN, Loom Overlooker, Morley, Yorkshire, do hereby declare the nature of our
invention for IMPROVEMENTS IN LOOSE REED LOOMS to be as follows :-
"
Our object is to produce a loose reed in looms that shall fall out entirely from the
"
ל,
slay beam and " top shell when the shuttle is "trapped," instead of remaining
In
fast to the "top shell as is the case in loose reeds now in general use.
carrying out our invention, we fix two or more iron castings to the slay beam,
the said iron castings having each a slot made in them. Into these slots we
place a flat iron weft bar, which bar runs the full length of the slay; into the
said slots and alongside the weft bar, we place an iron loose leaf, the same length
as the weft bar, the loose leaf being for the purpose of holding the slay in
position. At each end of the loose leat, we fix a pivot, these pivots being made
to work in two iron castings, one at each end of the slay beam, the said castings
being fixed inside the slay beam. On each end of the loose leaf, we also make a
lever to which we fix springs, these levers acting in such a manner, when the
loom is in operation, that they hold the slay firm until the shuttle is " trapped
in the shed, in which case, the said levers allow the loose leaf to fall, and the
slay then falls out of the slay beam and top shell entirely.
To the flat iron weft bar, we fix two pegs, one at each end, and to these pegs,
we fix strings of leather, twine or other suitable material; the said strings we
carry over pulleys which are fixed to the top shell, and then fasten them to a
spring which hangs from the centre of the top rail of the loom. We also make
two square holes in the weft bar, one at each end, the said square holes fitting on
to two pegs which are fixed on the inner side of the slay beam.

Improvements in Loose Reed Looms.
SAM WEBSTER, Morley, Yorkshire, Overlooker, and WILLIAM WEBSTER AUSTIN,
Morley, Yorkshire, Overlooker, 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 :-
دو
Our object is to produce a loose reed in looms, that shall fall out entirely from
the "
slay beam
and top shell" when the shuttle is "trapped" instead of
remaining fast to the "top shell" as is the case in loose reeds now in general use.
In carrying out our invention, we fix two or more iron castings to the slay
beam, the said iron castings having each a slot made in them. Into these slots
we place a flat iron weft bar, which bar runs the full length of the slay, into the
said slots and alongside the weft bar, we place an iron loose leaf, the same length
as the weft bar, the loose leaf being for the purpose of holding the slay in
position.
At each end of the loose leaf we fix a pivot, these pivots being made to work
in two iron castings, one at each end of the slay beam, the said castings being
fixed inside the slay beam. On each end of the loose leaf we also make a lever
to which we fix springs, these levers acting in such a manner, when the loom is
in operation, that they hold the slay firm until the shuttle is "trapped” in the

page_text: shed, in which case the said levers allow the loose leaf to fall, and the slay then
falls out of the slay beam and top shell entirely.
To the flat iron weft bar we fix twot pegs, one at each, end, and to these pegs
we fix strings of leather, twine, or other suitable material, the said strings we
carry over pulleys which are fixed to the top shell; and then fasten them to a
spring which hangs from the centre of the top rail of, the loom.
We also make
two square holes in the weft bar, one at each end, the said square holes fitting
on to two pegs, wbich are fixed on the inner side of the slay beam:
Figure 1. shows a section of the top rail A, A, top shell, A¹, A', slay B, B,,
slay beam C, C, and bottom front rail D, D.
In carrying out our invention we fix three or more iron castings E, E, E, to
the slay beam, the said castings being made with a slot as at Figure 2.
Into
these slots we place the flat iron weft bar F, F, to which. we give a rising &
falling motion; the said weft bar runs the full length of the slay B, B.
Behind the bottom part of the slay B, B, we place a loose leaf of iron G, G,
the same length as the weft bar, the said loose leaf being for the purpose, of holding
the slay in position. The said loose leaf is fastened to the slay beam C, C, by
pivots at the ends of loose leaf or by hinges H, H.
6
The loose leaf is held in an upright position by springs H', H¹. When the
loom is working these springs are so fixed that they hold, the loose leaf firmly,
but when pressure is brought to bear on the loose leaf by the shuttle being
trapped," they allow the loose leaf to fall easily. At J we fasten, the end of
a string of leather and carry it over pulleys K, L, M, L,. K2, and fasten the
other end at J2. The pulley M is then connected to the spiral spring P, which
hangs from the top rail. A. By a similar arrangement, the string of leather
could be carried over pulleys and. fastened to a spiral spring on the bottom front rail.
When working, the slay is put into the top shell and slay. beam in the usual
manner.
The action of our invention is as follows:-When the loom is working, as the slay
beam moves towards the front top rail of the loom, the string of leather fastened
at J, J2, and connected with spring P, gradually tightens, owing to being held by
spring P, this causes the weft bar to rise just before the slay strikes the cloth. When
the slay beam recedes, the weft bar falls again to its original position. Should the
shuttle be "trapped" in the shed when the loom is working, the weft bar being below
the bottom of the loose leaf, the shuttle striking against the slay causes the slay to
push the loose leaf backwards, and thus the slay falls out entirely from the top shell
and slay beam.
Having now particularly described and ascertained' the nature of our said
invention and in what manner the same is to be performed: we claim :-
1. The entirely loose reed.
2. The loose leaf.
3. A weft bar rising and falling at every pick of the shuttle, and the working of the
said' waft bar by the string of leather and spring as described.
