THOMAS GRIMSHAW of 196 Redlam, Blackburn, in the County of Lancaster,
Overlooker, do hereby declare the nature of this invention to be as follows:-
This invention relates to improved apparatus for releasing the reed, when the
shuttle is "trapped" or caught in the shed and the object is to secure the desired
release of the shuttle and at the same time make the "going part" lighter by
dispensing with certain parts of the loom as heretofore constructed.
According to this my invention I dispense with the stop rod, and duck bills, and
the reed case is made fast, the bottom of the reed resting on two upright rods having
Theads, the bottom ends of the Trods, rest upon projecting lugs or brackets, secured
to a rod, which passes from end to end of the loom, and which rod is secured by
bracket to the bottom end of the slay swords.
On the said rod is a segment of a ratchet wheel on which operates a catch or paw]
free to move in a bracket bolted to the front rail of the loom. This catch or pawl is
operated from the swell of one shuttle box, on the swell is a finger operating a lever,
or cranked rod, which raises the catch or pawl out of gear with the ratchet, when the
shuttle enters the box. The swell of the opposite shuttle box operates a like finger
lever or cranked rod, which gives a slight motion to another rod extending to, and
operating the catch or pawl.
The action is as follows:-When the loom is in motion, the slay swords give a
partial rotary motion to the rod secured to them and which carries the ratchet and
two projecting lugs. During the time the shed is open and the shuttle is crossing the
rail the catch or pawl being in gear with the ratchet wheel, holds the same and
prevents the rod and projecting lugs having a partial rotary motion given them and
so the reed is loose by reason of the two T headed rods, on which the reed rests lifting
the same clear of and above the reed case and allowing the reed to swing freely on its
cap. But when the shuttle enters the box it operates through the swell and lever, the

page_text: catch or pawl as described and raises the latter out of gear with the ratchet and allows
the same and the rod having the projecting lugs to have partial rotary motion and the
lugs slightly lower the T headed rods and the reed drop into the case and is "fast."
If the shuttle fails to box, the catch or pawl being in gear with the ratchet, the lugs
or projections do not move and the reed remains loose.

COMPLETE SPECIFICATION.
Improvements in Loose Reed Motions of Looms for Weaving.
I, THOMAS GRIMSHAW of 196 Redlam, Blackburn in the County of Lancaster,
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 :-
This invention relates to improved apparatus for releasing the reed, when the
shuttle is trapped or caught in the shed and the object is to secure the desired release
of the reed and shuttle and at the same time make the " going part" lighter by
dispensing with certain parts of the loom as heretofore constructed.
According to this my invention I dispense with the stop rod and duck bills, and the
reed case is made fast, the bottom of the reed resting on two upright rods having
Theads the bottom ends of the Ṭ rods rest upon projecting lugs or brackets, secured
to a rod, which passes from end to end of the loom and which rod is secured by
bracket to the slay swords.
On the said rail is a finger which is operated by a catch or pawl free to move on a
bracket bolted to the front rail of the loom. This catch or pawl is operated from the
swell of one shuttle box, on the swell is a finger operating a lever or cranked rod,
which raises the catch or pawl out of gear with the finger when the shuttle enters the
box. The swell of the opposite shuttle box operates a like cranked lever or rod
which gives a similar motion to another rod extending to and operating the catch
or pawl.
The Action is as follows
and fro motion to the rod
-
-When the loom is in motion the slay swords give a to
secured to them and which carries the finger and two
projecting lugs on which the T rods rest. During the time the shed is open and the
shuttle is crossing the race the catch or pawl being in gear with the finger, holds the

page_text: same and prevents the rod and projecting lugs having the to and fro motion given
them and so the reed is loose by reason of the two T headed rods, on which the reed
rests lifting the same clear of and above the reed case and allowing the reed to swing
freely on its cap.
But when the shuttle enters the box it operates through the swell and lever, the
catch or pawl as described and raises the latter out of gear with the finger and allows
the same and the rod having the projecting lugs to have the to and fro motion and
the lugs slightly lower the T headed rods and the reed drops into the case and is
fast." If the shuttle fails to box, the catch or pawl being in gear with the finger,
the lugs or projections do not move and the reed remains loose.
--
Such being the nature and object of this my said invention, the following is a
complete description of saine reference being had to the accompanying drawings:
Fig. 1 is a sectional elevation of a part of loom having my improvements applied
thereto.
Fig. 2 is a front elevation of Fig. 1.
Fig. 3 is a sectional elevation of part of loom shewing in a modified form position
of the several parts when the shuttle has boxed.
Fig. 4 is a similar view to Fig. 3 but shewing the position assumed by the several
parts when the shuttle has been caught and the reed forced out.
Fig. 5 is a front elevation of Fig. 3.
The several views on sheet 5 are parts detached and drawn to an enlarged scale.
According to this invention the reed case 1 is constructed similar to an ordinary
fast reed case, the bottom of the reed 2 resting on the T heads of two upright
rods 3-4, these upright rods 3-4 are supported and carried in brackets 5-6 the
brackets themselves being carried on the rod or shaft 7 extending across the loom and
secured to the slay swords S, with the to and fro or rocking motion of the slay
swords 8 a similar motion is imparted to the rod or shaft 7 and consequently to the
brackets 5-6 and upright rods 3-4. When the shuttle 9 enters the box it operates
through the swell 10 on the cranked rod 11 the cranked and lower end of which
acting on the finger 12 of the catch or pawl 13 free to turn on its fulcrum 13ª and
secured to the frame of the loom by the bracket 14", raises the same above and clear
of the finger 14 on the rod 7 and the reed 2 remains fast. But in case the shuttle 9
fails to box then the rod 11 finger 12 and catch or pawl 13 not being operated, the
catch 13 hooks on to the finger 14 and at the forward movement of the slay $ the shaft 7
and brackets 5-6 and uprights rods 3-4 remain stationary and the reed case 1 and
slay swords & moving on their centre the T headed rods 3-4 are caused to rise in
the bottom of the reed case 1 and consequently the reed 2 is lifted out of its case 1
and is free to swing in its cap. There is also a third rod 15 carried on a bracket 6 on
the rod 7 and operated as above described the top end of this rod during the ordinary
running of the loom remains flush or level with the bottom of a recess 16 in the slay
beam, if the shuttle fails to box, this rod 15 will protrude further in the recess 16 and
will during the beat up come in contact with the finger 17, on the lever of the weft
fork and pressing against the same pushes the knocking off handle 18 out of its holding
catch and thus stops the loom.
Referring now to Figs. 3-4 and 5 it will be seen by Fig. 3 that when the shuttle 9
enters the box it operates through the swell 10 the lever 19 which turning on its
fulcrum 20 raises the end 21 and also raising or turning the finger or "bill" 22 clear
of and above the
"bill
33 23. In case the shuttle 9 fails to box, then the parts 19,
21-22 not being operated and the "bill" 22 not being raised it passes underneath
the bill 23 (see fig. 4) and depresses 22 and turning the shaft 7 on which is the
bracket 6 the end 25 of which and the T headed levers 3-4 are consequently raised
and the reed 2 lifted out of its case 1 and is consequently "loose."
The spring 21 is to allow a little play when the bill" 22 passes beneath 23 and the
shuttle has not boxed.
It will be seen that the reed case 1 is made similar to the ordinary "fastened
case and thus when the shuttle boxes the reed 2 remains perfectly rigid for the
beat up."

page_text: Having now particularly described and ascertained the nature of this my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. The combination of parts such as described and illustrated by Figs. 1 and 2
whereby when the shuttle is trapped the reed is raised in its casing and its lower end
set free or loose.
2. The combination of parts such as described and illustrated by Figs. 1 and 2 for
setting free or " loose
the reed when the shuttle is trapped in connection with the
parts 6-15-17 for operating the weft fork and stopping the loom as described.
3. The construction, combination, and arrangement of parts illustrated by Figs. 3,
4 and 5 of the annexed drawings and herein fully described for lifting the reed and
setting the same free or loose when the shuttle is trapped.
