Improvements in Shuttle Checking and Loose Reed Apparatus
for Looms.
I CHARLES THOMPSON, of 2 St. James's Place, Otley Road, Baildon, in the
County of York, Mill Furnisher do hereby declare the nature of this invention to
be as follows:-
-
This invention relates firstly to improvements in appliances whereby I am
enabled to dispense with the check strap in looms for weaving, and at the same time
to cause the parts to work more freely and with less friction.
Secondly to improvements in the method of and means employed for releasing
the reed, and allowing the same to swing freely in its cap, and also for pushing
back from the front the box back, which then becomes loose, when from any cause
the shuttle is "trapped" in the shed or fails to "box" correctly.
According to this my said invention referring firstly to the appliances for
dispensing with the check strap, I fix at, or near, the outer end of each shuttle
box a bracket or stud serving as a fulcrum for, and carrying, a curved finger, to
the free end of each curved finger I attach a short loop, or strip of leather, and
the picker spindle is passed through the loop, or through a hole in the strip, the
latter, or the loop, being behind the picker as is the ordinary check strap. The
two curved fingers are attached to each other by a band, or strip of steel, or other
metal, which passes along the front of the slay beam, and is guided, and kept in
position by leather or other brackets.
The action of the above described shuttle checking appliance is similar to
the ordinary device, but is more durable and economical, and gives better practical
results.
The improvements relating to the loose reed motion are as follows:-
--
The reed is mounted, and carried as ordinary, and at each end of the reed motion
rod is fixed a curved finger which extends to the front of the slay beam, and at
the outer end of each curved finger is fixed a wire, or rod which passes through
a hole in the slay beam, and each wire or rod is attached to the shuttle box back
nearest to it. The shuttle box back is made loose i.e. the spring, or springs as
heretofore employed are dispensed with.
On one or both of the curved fingers above mentioned I mount an anti-
friction bowl or runner which rests on an inclined, or curved finger formed on
one end of a lever attached to the slay sword by pin, or fulcrum stud, and the other
end of the lever is held by means of a spiral spring fixed to any convenient part of
the loom.
The inclined or curved portion of the lever may be held in contact with the
runner in the manner above described or by spiral spring pressing in an upward
direction or by other means, and one of such runners, levers and appliances
connected therewith may be fixed to each slay sword, or to one only as may be
desired.
The action is as follows:--If from any cause the shuttle is "trapped" or fails
to "box," the pressure of the shuttle on the reed forces, the latter slightly back-
wards, and operating in the ordinary, and well known way gives a part revolution
to the reed motion rod, the latter communicates motion to the curved fingers, and
they, by the wires, or rods above mentioned, push back, or open both the shuttle
box backs, and at the same time the runner is caused to move along the inclined,
or curved end of the lever against which it rests until the runner has passed above,
or clear of the incline or curve, whereon the reed, and the backs of both shuttle

page_text: boxes will be loose, and open and so remain until they are again placed in position
by the attendant on the loom.

I CHARLES THOMPSON of 2 St. James's Place, Otley Road, Baildon, in the
County of York, Mill Furnisher, 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 firstly to improvements in appliances whereby 1 am enabled
to dispense with the check strap in looms for weaving, and at the same time to
cause the parts to work more freely and with less friction.
Secondly to improvements in the method of and means employed for releasing
the reed, and allowing the same to swing freely in its cap, and also for pushing back
from the front the box back, which then becomes loose, when from any cause the
shuttle is "trapped" in the shed or fails to "box" correctly.
According to this my said invention referring firstly to the appliances for
dispensing with the check strap, I fix at, or near, the outer end of each shuttle
box a bracket or stud serving as a fulcrum for, and carrying a curved finger to
the free end of each curved finger 1 attach a short loop, or strip of leather, and
the picker spindle is passed through the loop, or through a hole in the strip, the
latter or the loop, being behind the picker as is the ordinary check strap. The two
curved fingers are attached to each other by a band, or strip of steel, or other metal,
which passes along the front of the slay beam, and is guided, and kept in position
by leather or other brackets.
The action of the above described shuttle and picker checking appliance is similar
to the ordinary device, but is more durable and economical, and gives better practical
results.
The improvements relating to the loose reed motion are as follows:-
The reed is mounted, and carried as ordinary, and at each end of the reed
motion or stop rod is fixed a curved finger forming a hand lever or handle which
extends to the front of the slay beam, and at the outer end or back of each a second
curved finger is fixed and passes to the back of the shuttle box nearest to it.
The shuttle box back is made loose i.e., the spring, or springs as heretofore
employed are dispensed with.
On each of the curved fingers or hand levers above mentioned I mount an anti-
friction bowl or runner which rests on an inclined, or curved finger formed on one
end of a lever attached to the slay sword by pin, or fulcrum stud, and the other
end of the lever is held by means of a spiral spring fixed to any convenient part of
the loom.
The inclined or curved portion of the lever may be held in contact with the
runner in the manner above described or by spiral spring pressing in an upward
direction or by other means, and one of such runners, levers and appliances
connected therewith may be fixed to each slay sword, or to one only as may be
desired.
The action is as follows:-If from any cause the shuttle is "trapped" or fails
to "box"the pressure of the shuttle on the reed forces, the latter, slightly back-
wards, and operating in the ordinary and well known way gives a part revolution
to the reed motion or stop rod, the latter communicates motion to the curved

page_text: fingers, and they are removed from contact with the loose backs of the shuttle
boxes and the trapped shuttle can push back or open both the shuttle box backs,
and at the same time the runner is caused to move along the inclined, or curved
end of the lever against which it rests until the runner has passed above, or clear
of the incline or curve, whereon the reed, and the backs of both shuttle boxes will
be loose, and open and so remain until they are again placed in position by the
attendant on the loom.
Such being the nature and object of my said invention the following is a
complete description of same reference being had to the accompanying drawings
in which
Fig. 1 is a front elevation of the "going part" of a loom having my improved
appliances for easing and stopping the momentum of the picker and shuttle and
dispensing with the check strap, and also my improved method of and means
employed for releasing the reed, and allowing the backs of the shuttle boxes to be
opened when the shuttle is "trapped" or fails to box.
Fig. 2 is a sectional elevation through line A. B. of Fig. 1.
Fig. 3 is a section through line C. D. of Fig. 1.
Fig. 4 is a front elevation of shuttle box having a loose or open back.
Fig. 5 is an end elevation shewing the appliances for holding the shuttle box
back in position when the shuttle "boxes."
Fig. 6 is an end view of part of Fig. 5 drawn detached in order to more clearly
shew its construction.
Fig. 7 is a front view of Fig. 6 the stop finger being shewn in this fig.
The remaining gs. are details.

According to this ny said invention and referring firstly to the improved means
and appliances employed for casing, and stopping the momentum of the picker and
shuttle on its "in or return movement after the "pick" has been made and the
shuttle expelled from the box whereby I am enabled to dispense with the use of
the check strap as heretofore employed. I fix at or near the outer end, and in the
front of each shuttle box 1 a bracket or stud 2 serving as a centre, or fulcrum pin
for, and carrying a curved finger 3, and to the free end of each curved finger 3 [
attach a short loop or strip of leather 4 which loosely encircles the picker spindle 5
such loop or strip of leather 4 being behind the picker 6 as is the case with the
ordinary check strap. The two curved fingers 3. 3. are attached to each other by
a band or strip of steel or other metal 7 which band 7 passes along the front of the
slay beam or race 8 and is guided or maintained in correct position by leather
lined, or fixed brackets 9. 9. (sce detail sheet 2) which are preferably of metal
screwed to the face of the slay beam or race 8 and between the metal portions 9. of
the brackets and the band or strip 7 place a piece of leather or rubber 10 and
the nip or grip of the latter on the strip or band 7 can, by the screws in the
brackets 9. be adjusted, and regulated that the loop of leather 4 will offer more
or less resistance to the picker 6 according as the picker is returned into the
box, (after the "picks") at a high or low speed. Spiral springs 94 9A
attached one end to the curved fingers 3. and the other to the slay beam 8 act as
buffers or checks, for breaking the force of the impact between the picker and
loop 4.
When one of the pickers 6 is thrown or carried to the outer end of the shuttle
box it will come in contact with the loop 4 and its impact with the latter will carry
the loop 4, and curved finger 3 along with it, as shewn at the right hand side of
Fig. 1 and the curved finger 3 will draw the band or strip 7 through the
brackets 9. 9. the frictional resistance offered by the latter and the resistance
offered by the spring 9" gradually easing and stopping the momentum of the
picker 6.
When the curved finger 3 at the right hand side of Fig. 1 is moved as above
described the band or strip 7 will move the curved finger 3 at the left hand side
of Fig. 1 towards the inner end of an entrance to the shuttle box, and when the

page_text: picker 6 comes in contact with the loop 4 on this finger 3 the above described
operation will be repeated.
Referring now to the loose reed motion
The reed 11 is mounted and carried as ordinary in the cap 12 and near each
end of the stop rod 13 is fixed a curved finger forming a hand lever, or handle 14
which extends to the front of the slay beam or race S. A curved finger 15 cast to
and forming a continuation of the finger 14 extends to and its extremity rests
against the back or loose part 16 of the open shuttle box 1 which is made as
shewn by Fig. 4 the part 16 of the back being hinged at 17 and the end of the
finger 15 maintains it in the correct position during the ordinary running of the
loom.
On each one of the curved fingers or handles 14 I mount an anti friction bowl or
runner 18 which rests on an inclined or curved finger 19 formed on one end of a
lever 20 loosely mounted on the pin or fulcrum stud 21 fixed to the slay sword 22
and the inclined finger 19 is pressed against the runner 18 by means of the spring 23
one end of which is fixed to the lower end of the lever 20 and the other to the
front frame of the loom. The ordinary stop finger 24 which by coming in contact
with the frog 25 prevents the "beat up" being made when the shuttle has failed to
box, is connected by cord, strap, or wire 26 or cord and lever, the cord, strap or
wire passing over the guide pulley 27, fixed to the slay beam or race 8, with the
curved finger 14 above mentioned, and if this curved finger 14 be raised a spiral
spring 28 draws down the stop finger 24 so that the latter will meet the frog 25 at
the forward movement of the loom.

"
The action is as follows:-If from any cause the shuttle is trapped, or fails to
box correctly the pressure of the shuttle on the reed 11, or on the part 16 of the
shuttle box the same will be forced backwards, or outwards and the reed case 29
being also turned backwards its supports 30 will, in the ordinary way give a part
revolution to the stop rod 13 the latter turning the curved fingers 15. 15. (which
are mounted on the stop rod) and they are removed from contact with the backs 16
of the shuttle boxes 1. 1. and no damage can be caused to the "shed". o or warps
by the shuttle. At the same time the runner 18 is caused to move along or up the
inclined finger 19 against which it rests until the runner 18 has passed above, and
clear of the finger 19 whercon the reed 11. reed case 29. and the backs 16. 16. of
both shuttle boxes 1. 1. will be maintained in the "open position until the
attendant on the loom presses down the handle, or fingers 14. 14. and so places the
several parts in their correct working positions.
29
When the fingers, or handles 14 are raised by the shuttle being trapped
the springs 28 will draw down the stop fingers 24 as above described so that the
latter will at the forward movement of the loom come in contact with the "frogs" 25
and arrest the motion of the loom before the beat up" and consequently before
damage has been done.
The reed 11. and backs of the shuttle boxes 1. 1. are made fast before the "beat
up" only when the shuttle has boxed correctly by a finger or fingers 14 on the stop
rod 13 passing under a projection or inclined surface fixed to the front part of the
loom the rod 13 being thereby locked and prevented from making a part revolution
in the well known manner.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The curved fingers 3 loops or straps 4 metal strip or band 7 and brackets 9.9
with or without spring 9" all in combination as and for the purpose herein fully
described and substantially as illustrated by the annexed drawings.
2. The stop rod 13 curved fingers 14. 15 runner 18 inclined finger 19 stop
finger 24 all in combination operated and operating as and for the purpose herein
fully described and substantially as illustrated by drawings annexed.

page_text: 3. The stop rod 13 curved finger 14. 15 runner 18 and inclined finger 19 all in
combination operated and operating as and for the purpose herein fully described
and substantially as illustrated by the drawings annexed.
