I CHRISTOPHER CATLOW, of 22 Clifton Street, Burnley, in the County of
Lancaster Overlooker, do hereby declare the nature of my said invention for
"IMPROVEMENTS IN APPARATUS FOR LOCKING, AND UNLOCKING, THE REEDS, OF
LOOMS, FOR WEAVING," to be as follows:—
This invention consists, of improved combination of apparatus, to be employed
for locking, and securely holding the reed during the beat up of the latter, and for
releasing or unlocking the same, when the shuttle is trapped, or caught in
the shed.
Under or forming a part of the slay cap, or hand rail, I employ a hollow casting,
which encloses a longitudinal shaft, from the underpart of which, extend vertical
fingers, and from the back are horizontal fingers or locking pieces-The lower part
of the reed, rests in a longitudinal groove, formed in the slay beam, its upper part
is received within the hollow casting, between which and the vertical fingers
referred to, it is held.
In each of the horizontal fingers, or locking pieces, is a hole, through which the
upper end of a locking catch is passed its lower end being attached to a bracket.
When the reed and going part advance to beat up the weft, if the shuttle has
crossed the race, and shed properly, pins or projections, attached to the slay swords,
or to the "going part," will come in contact with the locking catches referred to,
and moving the same across the hole in the locking fingers or pieces, so as to bring
a projecting lip, or catch, upon the horizontal locking piece and the reed is held
firmly in position for the beat up-But should the shuttle be caught or trapped in
the shed, the pressure upon the reed, causes the upper part of the latter, to force
the vertical fingers backwards thereby partially turning the longitudinal shaft, the
horizontal fingers or locking pieces of which are moved radially upwards and thus
pass the hole therein above the lip of the locking catch, the reed being freed at its
upper end, flies back and breakage is avoided-A spiral or other spring, attached to
the locking piece, draws down the latter, and the parts resume the original position,
when the shuttle is removed.

Improvements in Apparatus for Locking and Unlocking the
Reeds of Looms for Weaving.
I CHRISTOPHER CATLOW, of 22. Clifton Street, Burnley, in the County of
Lancaster, do hereby declare the nature of my said invention for "IMPROVEMENTS
IN APPARATUS FOR LOCKING AND UNLOCKING THE REEDS OF LOOMS FOR WEAVING
"
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention consists, of improved combination of apparatus, to be employed
for locking and securely holding the reed during the beat up of the latter, and for
releasing or unlocking the same, when the shuttle is trapped, or caught in
the shed.
Such being the nature and object of my said invention, the following is a 1
complete description of same, reference being had to the accompanying drawings
forming a part of this specification in which :-
Fig. 1 is a front elevation of part of the slay of a loom having my improvements
applied thereto.
Fig. 2 is an end elevation of same partly in section shewing the reed in position 1
for beating up.
Fig. 3 is an end elevation enlarged scale illustrating reed in its working position
for beating up.
Fig. 4, is a similar view illustrating the shuttle caught or trapped in the shed
and the reed thrown out of its working position.
The slay cap or hand rail 1 I make hollow and secure it by bolts 2 and 3 to the
slay swords 4, 5-Under the hollow cap is the longitudinal shaft 6 carried by
brackets 7, 8 fixed to the slay sword-From the underside of the shaft 6 are the
fingers or web 9 and at 10 are horizontal fingers to which the connecting rods 11
are attached and to the fingers 12, the outer end or lip 13 of which rides or passes
over the duck bill 14 so long as the shuttle boxes properly but when the shuttle is
caught or trapped in the race (see Fig. 4) the connecting rod 11 will be raised and
the point 13 of the lever 12 will pass under the duck bill 14 tilting the lever 12
and by the connecting rod forcing up the part 10 and throwing out the fingers or
web 9 so releasing the reed 15 as will be understood.
It will be seen that whilst the shaft 6 is free to move and release the reed the
hand rail proper is fixed and stationary in lieu of moving with the reed as
heretofore so that if the operator should have his hand on the "hand rail" when a
trap occurs the reed is still free to move back.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The improved apparatus herein described wherein is employed the free
shaft 6 fixed hollow hand rail or slay cap combined with the fingers or web 9,
connections 11, and levers 12.
2. The improved apparatus wherein is employed the moving shaft 6 in
combination with a hollow and fixed hand rail or slay cap as and for purpose
herein fully described.
