"IMPROVEMENTS IN LOOMS FOR WEAVING"
"
This invention relates. Firstly to improved mechanism in connection with fast
and loose reed looms the apparatus comprising mechanism whereby the reed is held
securely when "beating up but when the shuttle is trapped or does not box
properly, the reed is set free, the break is applied and the loom knocked off or
stopped automatically and instantly.
Secondly, to an improved adjustable box front.
Thirdly An improved attachment for the warp beam ropes.
Lastly Improvements in loom temples. According to this my invention I
dispense with the ordinary reed rod and fingers and apply to the stay beam two
finger catches one of which acts in connection with the V for holding the reed fast
for the beat up.
Should the shuttle be trapped the pressure on the reed raises the second catch
finger where it is held, the V catch being raised so as to pass over the latter, the
reed motion on being forced back or open releases at the other end of the loom a
catch permitting a hooked faller to descend and engage with a catch piece or
projection on the boss of a stud to which the brake strap link is connected whereon
the brake is instantly and self actingly applied an arm and incline connected with
brake motion acts on the spring stop handle and the motion of the loom is arrested
by simultaneous application of the brake and the transfer of strap from fast to
loose pulley.
The rope of the warp beam after being passed round the neck of the beam is
enclosed by a clip or hinged metal collar or casting which also carries guide
pulleys through and around which the weight rope is passed before attaching
[Price 8d 1

page_text: to the weight rope lever whereby any desired amount of grip may readily be
secured
The box front is levelled and a loop formed therein for the check strap the
front being adjustable so as to accommodate the size of box to any shuttle the
frame having lugs and adjusting screws for determining and securing the front in
position.
In the construction of loom temples I mount all the wheels upon a stud
each wheel has side bosses whereby the whole of the wheels move simultaneously

This invention relates-Firstly to improved mechanism in connection with fast
and loose reed looms the apparatus comprising mechanism whereby the reed is
held securely when "beating up" but when the shuttle is trapped or does not box
properly the reed is set free-the break is applied and the loom: knocked off or
stopped automatically and instantly-Secondly-to an improved adjustable box
front Thirdly-An improved attachment for the warp beam ropes-Lastly,
Improvements in loom temples
According to this my invention I dispense with the ordinary reed rod and fingers
and apply to the 'slay beam two or more finger catches one of which acts in
connection with the V catch for holding the reed fast for the beat up-Should the
shuttle be trapped the pressure on the reed raises the second catch finger where it
is held the V catch being raised so as to pass over the latter-the reed motion on
being forced back or open releases at the other end of the loom a catch permitting
a hooked faller to descend and engage with a catch piece or projection on the boss
of a stud to which the brake strap link is connected whereon the break is instantly
and self actingly applied an arm and incline connected with brake motion acts
on the spring stop handle and the motion of the loom is arrested by
simultaneous application of the brake, and the transfer of strap from fast to loose
pulley..
The neck of the beam is enclosed by a clip or hinged metal collar or casting
lined with paper, which also carries guide pulleys through and around which the
friction chain or rope is passed. before attaching to the tension rod or lever whereby
any desired amount of grip may readily be secured. The box front is levelled
and a loop formed therein for the check strap the front, being adjustable so as tọ

screws for determining and securing the front in position. In the construction of
loom temples I mount all the wheels upon centre bosses whereby the whole of the
wheels move simultaneously and the cost and labour of cutting out spaces for the
wheels as heretofore is obviated.
Such being the nature and object of this my invention I will now proceed to
describe the same in detail and in order that the invention may be fully understood
I have hereunto annexed 4 Sheets of drawings illustrative thereof and have marked
same with figures of reference, like figures denoting like parts on the drawings.
Thompson & Improvements in Looms for weaving.
accomodate the size of box to any shuttle the frame having lugs and adjusting
screws for determining and securing the front in position. In the construction of
loom temples I mount all the wheels upon centre bosses whereby the whole of the
wheels move simultaneously and the cost and labour of cutting out spaces for the
wheels as heretofore is obviated.
Such being the nature and object of this my invention I will now proceed to
describe the same in detail and in order that the invention may be fully understood
I have hereunto annexed 4 Sheets of drawings illustrative thereof and have marked
same with figures of reference, like figures denoting like parts on the drawings.
DESCRIPTION OF THE DRAWINGS
Fig 1 is a front elevation of the slay. Fig: 2 is an end elevation of same..
Fig 3 is a sectional elevation through line A. B. of Fig: 1-Fig: 4 is a sectional
elevation through line C. D of Fig: 1-Fig: 5 is a sectional elevation of slay beam:
shewing improved apparatus for use in connection with fast reed-Fig. 6 is an
elevation of the back of Fig 5-Fig. 7 is an end elevation of warp beam and
improved holding and letting off apparatus Fig 8 is a side elevation of Fig: 7-
Fig. 9 is a side elevation of my improved temple Fig: 10 is a plan view of
Fig: 9-Fig: 11 is an end elevation of Fig: 9 partly in section-Fig: 12 is a
detail or part of Fig: 11 detached.
On Sheet 4 Are enlarged view of details or separate parts.
At 1 is the slay beam, 2 is the reed, 3. 3 are finger catches, hinged on pin 4,
carried by brackets 5 and 6 each of the fingers 3. 3. when the reed beats up and is
free from obstruction, engages with V wedge holding piece 7 and the reed is
securely held for the beat up by the levers 8 and 9. The lever 9 having friction
bowl 10 on its other end, which at each beat up runs along the face of the side
plate 11 (carried by the end frame of the loom) the part 12 of this plate is loose
being hinged on the pin 13 and held by spring 14 so that should a shuttle be
trapped the finger 8 acts on the end of the lever 9 and the pulley 10-on its other
end then acts upon and forces back the hinged part 12 of the side plate 11 so
permitting the finger 8 to clear the lever 9 and the reed is loose--whereon the
end 15 of the lever 16 lowers on its fulcrum 17 and its other end 18 lifts the
catch 19 on its fulcrum pin 20 whereon its notched end 21 engages with the catch
piece 22 which it pulls and by the link 23 connecting rod 24 applies simultaneously
the brakes 25 and 26 the movement of the latter by the rod 27 pushes off the
spring stop handle 28 and stops the loom. In a fast reed loom (see Figs 5 and 6)
the swell 29 being forced back by the shuttle on its entrance to the shuttle box
moves the lever 30 on its fulcrum 31 whereon the lever 32 by link 33 moves the
lever 18 on its fulcrum pin 17 and raises the end 21 clear of the lug 22. When
the shuttle fails to box there being no action on the swell and mechanism just
described so that the catch end 21 engages with the lug 22 and the brake is applied
as described in reference to Fig: on the loose reed arrangement. The box
front 34 is provided with lugs and screw adjustment 35 passed through the slay
beam under the box bottom so that the space between the front 36 and back 37 of
the box can be adjusted or regulated to accomodate the loom to variation in size of
shuttles the check strap loop 38 is attached to the box front 34 and is moved and
adjusted along with the box front. The warp beam 39 has around its neck a
hinged clip 40 carried by brackets 41 attached to the loom end frame at 42. 42
are guide pulleys through and around which the chain or rope 43 is passed thence
to the tension rod 44 having clutch box 45 and hand wheel 46 and lock wheel 47
at 48 is a double tappet on the ordinary tappet shaft, which at each pick acts upon
the swell on the lever 49 and by means of the rope or chain 43 puts the required
drag on the neck of the beam, the neck is encased in paper as shewn at 50, Fig 7-
The like apparatus is applied to each end a neck of the warp beam-At 51 are
the wheels of the temple having internal eccentric loose boss 52 on the stud 53 so
as to admit all the wheels being close to each other and moving simultaneously and

page_text: also dispenses with the requirements of the centre or spacing flanges as heretofore
employed Having. thus fully described the nature and particulars of this my said
invention together with the manner in which the same is to be or may be performed
or carried into practical effect I would have it understood that what I claim as my
invention is
Firstly The general construction and combination of parts constituting the
improved apparatus for loose and for fast reed looms as shewn at Fig. 1. 2. 3.5
and 6 of the drawings.
.
Secondly. The apparatus comprising the hinged movable part 12 combined with
the levers 9 and finger 8 as described and illustrated by Figs 1*, 1* sheet 4.
Thirdly-The brackets and fingers in combination and applied to the slay beam
for purpose herein described whereby the ordinary stop rod is dispensed with and
as illustrated by drawings.
Fourthly-The, combination of brakes 25 and 26 connections 23 and 24 lug 22
and hook 21 as described and illustrated by drawings.
Fifthly The combination of front for shuttle box check strap. loop both
movable by screw adjustment as shewn by drawings and described herein.
_ Sixthly The improved warp beam letting off motion comprising the paper
lined clip and pulleys connecting chain or cord and tension rod as shewn and
described herein.
Lastly-The improvements in temples as herein described and illustrated by
drawings.
