We, CHARLES BOWLES, of Ligoniel in the County of Antrim, Flax Spinner and
Linen Manufacturer, and WILLIAM CAIRNS of Ligoniel, in the County of Antrim,
Factory Manager do hereby declare the nature of our invention for IMPROVEMENTS
IN THE TAKE-UP MOTION OF LOOMS FOR WEAVING AND IN THE ARRANGEMENT
FOR STOPPING AND REVERSING SAME to be as follows:-
This invention relates to the take-up motion in looms for weaving and is
designed to make this notion steadier and more uniform, so that the weft may
be put into any textile fabric with more regularity than at present, and the thick
and thin places, so common in goods made by power looms, be thereby avoided.
By our arrangement the ratchet wheel and catch, by which the take-up motion
in power looms is at present actuated, are entirely done away with. A short
auxiliary shaft is placed inside the framing of the loom, at one end, and at right
angles to the picking shaft. A bevil wheel on one end of this auxiliary shaft is
driven by a bevil wheel on the picking shaft, while on its other end a worm works
into a stud wheel, moving the latter forward one tooth for every pick of weft put
into the cloth. The change pinion is placed on the axis of the stud wheel, and
through it the required motion is communicated to the sand or emery beam, by a
train of wheels, in the usual manner. There is also an arrangement by which the
take-up motion can be thrown out of gear, and then reversed, when this is
necessary either in case of ripping out or for any other purpose.
By
The said arrangement is as follows: When the loom is stopped by the breakage
of the weft a lever is thrown back into a notch in an L shaped opening in the
breast beam. The motion thus given to the lever is communicated in the case of
a left-hand loom through a rod (which however is dispensed with in a right-hand
loom) and other levers to a reversing bar, moving it forward. In a right handed
loom one of these levers and the first mentioned lever are united on a stud.
means of clutches one of the bevil wheels is thus thrown out of gear with the
other, and the take up motion instantly stopped; while by the same movement a
spur pinion is put into gear with a hand wheel, which enables the weaver to let off
or take up the cloth at pleasure. When by putting on the loom or by any other

the reversing bar is at once drawn back by a spiral spring and the bevil wheels
instantaneously thrown into gear again.
The arrangement is such that the loom cannot be started by means of the handle
without a wire releasing the lever first above mentioned from the notch, and thus
putting the take up motion into gear again, as described above. Any carelessness
on the part of the worker is thus guarded against.
Improvements in the Take-up Motion of Looms for weaving,
and in the Arrangement for Stopping and Reversing same.
We, CHARLES BOWLES, of Ligoniel, in the County of Antrim, Flax Spinner and
Linen Manufacturer, and WILLIAM CAIRNS of Ligoniel, in the County of Antrim,
Factory Manager, 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 the take-up motion in looms for weaving, and is
designed to make this motion steadier and more uniform, so that the weft may
be put into any textile fabric with more regularity than at present, and the thick
and thin places so common in goods made by power looms be thereby avoided.
By our arrangement the ratchet wheel and catch, by which the take-up motion
in power looms is at present actuated are entirely done away with. A short
auxiliary or counter shaft is placed inside the framing of the loom, at one end, and
at right angles to the tappet shaft.
A bevil wheel on one end of this auxiliary or counter shaft is driven by a bevil
wheel on the tappet shaft, while near its other end a worm works into a worm
wheel, moving the latter forward one tooth for every pick of weft put into the
cloth. The change pinion is placed on the axis of this worm wheel and through it
the required motion is communicated to the sand or emery beam, by a train of
wheels, in the usual manner. There is also an arrangement by which the take-up
motion can be thrown out of gear, and then reversed, when this is necessary either
in case of ripping out or for any other purpose.
The said arrangement is as follows: When the loom is stopped by the breakage
of the weft a lever is thrown back into a notch in an L shaped opening in the
breast beam. The motion thus given to the lever is communicated in the case of

page_text: a left-hand loom through a shaft (which however is dispensed with in a right-hand
loom) and other levers to a reversing bar, moving it forward. In a right banded
loom one of these levers and the first mentioned lever are united on a stud. By
means of clutches one of the bevil wheels is thus thrown out of gear with the
other, and the take up motion instantly stopped, while by the same movement a
spur pinion is put into gear with a hand wheel, which enables the weaver to let off
or take up the cloth at pleasure. When by putting on the loom or by any other
means the first mentioned lever is released from the notch in the L shaped opening,
the reversing bar is at once drawn back by a spiral spring and the bevil wheels
instantaneously thrown into gear again.
The arrangement is such that the loom cannot be started by means of the handle
without a wire releasing the lever first above mentioned from the notch, and thus
putting the take up motion into gear again, as described above.
Any carelessness on the part of the worker is thus guarded against.
Referring to the accompanying sheets of drawings Fig. 1 is an end elevation
partly in section of so much of a left-hand loom as is necessary to illustrate the
invention; Fig. 2 is a plan shewing a part of the arrangement employed according
to this invention; Fig. 3 is a front elevation partly in section, and Fig. 4 a plan
shewing the shuttle shelf, weft fork and adjacent parts.
Upon the tappet shaft 1 there is fixed a bevil wheel 2 gearing with a second
bevil wheel 3 on the countershaft 4. This latter shaft runs along the loom side,
and carries beside the bevel wheel 3 just mentioned, the worm 5, and the spur
pinion 9; of these three the worm is keyed fast, but the other two are secured by
feather keys so that they can slide endways, and thus be put in and out of gear
with their respective wheels. Or instead of sliding on keys, they may be loose,
and be put in and out of engagement with the shaft by means of sliding clutches.
The worm 5 gears with a worm wheel 6, fixed on a short spindle, which at the
other end carries a change wheel, connected by the train 8, 8, 8, with the sand or
emery roller. When the loom is at work the emery roller is thus driven uniformly
from the tappet shaft through the wheels 2 and 3, the worm and wheel 5 and 6,
and the train S, 8, 8. At such time the pinion 9 is out of gear with the hand
wheel 10. When the loom stopped by the action of the weft fork, the wheels 2
and 3 are put out of gear (or the latter is disengaged from the tappet shaft) and
the wheels 9 and 10 are put into gear, (or the former is engaged with the counter
shaft). The sand roller then ceases to revolve, although the loom may make
several more picks from its momentum. At the same time the sand roller can be
turned either way by the hand wheel 10.
When the weft fork lever B is forced back it is pressed against an arm or lever D
which is fixed to a shaft E and passes through an L shaped slot E' in the breast
beam E. This arm is elastic sideways, and catches on the edge of the slot which
holds it. The motion of the arm is transmitted through the shaft E and the
levers F and G to the sliding bar H, upon which are fingers or clutch forks I I
engaging with grooves in the bosses of the wheels 3 and 9. When this bar is
forced to the left by the action of the weft fork the wheels are operated as
described above.
When the attendant starts the loom again a wire C connecting the starting
lever A and the arm or lever D draws the arm D off the edge of the L slot, and
the spring K moves the bar H and returns the wheels to the working position.
According to a modification the pinion 9 is never taken out of gear with the
hand wheel 10, which revolves idly during the working of the loom.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed we declare that what
we claim is :-
-
1. In a loom for weaving the application in connection with the take-up motion,
of bevil gear or wheels, a shaft, and a worm and worm wheel through which the
take-up-motion can be driven, the arrangement being such that the bevil wheels

page_text: can be put out of gear and that then the worm and worm wheel remain in gear
and can be rotated by hand either backwards or forwards when the loom is at rest,
substantially as described.
2. In a loom for weaving furnished with means such as referred to in the
preceding claim for driving the take-up-motion, providing a toothed wheel on
the shaft that carries the worin and a hand wheel on a separate shaft or pin the
arrangement being such that the worm or counter shaft becomes geared to the hand
wheel so that it can be actuated thereby when the bevil wheels are put out of gear,
substantially as described.
3. In a loom for weaving in which the take-up-motion is driven through bevil
gear and worm gear providing an arm or lever so arranged in relation to the weft
fork lever and so connected to a part of the bevil gear that the said arm or lever
will be operated by the weft fork lever when it is actuated on the breakage of the
weft and will then disengage the bevil gear, substantially as described.
4. In a loom for weaving having a take-up-motion and driving gear such as
referred to in claim 3 connecting the starting handle A to the driving gear of the
take up motion in such a manner as to prevent the loom being started without
also starting the take up motion, substantially as described.
5. The combination of parts constituting the improved combined take up motion
and driving gear for same constructed arranged and operating as shown in and
described with reference to the drawings annexed.
Dated this 28th day of October 1886.
