The object of this invention is to simplify the taking up motion for which
Letters Patent No 8909 dated June 13th 1884 were granted to me, and to enable
the weaver to use the "knocking-off" lever when employed for the purpose of
stopping the loom by hand without lifting the taking up catches, and thus making.
a thick line across the cloth, in looms fitted with this or other similar taking-up
motions.
For this purpose I dispense with the "trigger-rod" and I mount the "retaining
catch" upon a stud attached to a convenient part of the loom side, or it may be
mounted upon the horizontal shaft hereinafter mentioned.
The weft-fork bracket is not attached to the "knocking-off" lever but its end
abuts against the side of the same, when used so that the weft fork can act
against the "knocking-off" lever but the latter can be moved so as to stop the loom
without acting upon the weft fork or upon the "taking-up" catches.
The weft-fork bracket is carried upon a vertical arm fixed at or near one end
of a horizontal shaft which extends across the loom and upon this shaft is also
fixed a catch which lifts one of the two "taking-up-catches" carried by the
monkey-tail" and also the retaining catch of the quadrant.
By this arrangement it will be seen that the quadrant and the taking-up wheel
are both at the same side of the loom and the apparatus can thus be applied to
the loom in a simpler and more economical manner, than heretofore, at the same
time that the weaver can if he desires, make use of the "knocking off" lever when
employed, or the ordinary stopping handles for stopping the loom by hand without
interfering with either the weft fork motion or with the taking-up or retaining
catches. In some cases I dispense with the "knocking-off-lever" and I fix on the
horizontal shaft (which carries the vertical arm above mentioned) a lever, crank,
or other projection which bears against the stopping-handle and when the weft
breaks or is otherwise absent, forces the said handle out of the notch and thus
stops the loom.

page_text: I GEORGE WOOD RHODES of Mersey Mills Hadfield in the County of Derby
Cotton Spinner do hereby declare the nature of my invention for "IMPROVEMENTS
IN THE TAKING-UP MOTION 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:-
The principal objects of this invention are first to simplify the construction of
a certain class of taking-up motion for looms, for which Letters Patent were
granted to me bearing date June 13th 1884 N° 8909 and to enable the weaver on
looms fitted with this patent motion to use the " knocking off" levér (when
employed) for the purpose of stopping the loom by hand without lifting the
taking-up catches and thus making a thick line across the cloth in looms fitted
with this motion, or other known taking up motion wherein the taking-up ratchet
wheel is allowed to run back when the weft breaks.
Another object of my invention is to dispense with the knocking off lever and
to substitute in place thereof a cranked lever (hereinafter described) which bears
against the stopping handle and when the weft thread breaks (or is otherwise
absent) forces the said handle out of the notch and thus stops the loom and
arrests the taking-up motion without letting the cloth run back.
The nature of my said invention will be readily understood on reference to the
annexed drawing and the following explanation thereof.
Fig. 1. on the drawing is a side elevation of so much of the loom frame as is
necessary for illustrating the application of my invention thereto; and Fig. 2 is
an elevation of a portion of the same with the "monkey-tail" lever and catches
removed. Fig. 3. shows the latter detached in elevation and plan.
Fig. 2 represents the arrangement which I propose to employ when the
"knocking-off lever" is dispensed with. Fig. 4 shows in detached plan and
elevation the form of the cranked lever which I propose to employ in place of the
said "knocking off" lever.
a, a is part of the frame of the loom, b, b the slay sword, and c, c the ordinary
"taking-up" ratchet wheel. The latter, with the ordinary taking up wheels, are
indicated by the pitch lines or circles in Fig. 1. d, d is the weft fork.
In carrying out my invention I dispense with the “trigger-rod" and I mount
the retaining catch e, e upon a lever f, working on a stud g, or if preferred, it
may be hung direct upon a stud (or it might be mounted upon the horizontal
shaft h, h hereinafter mentioned).
The weft fork bracket i, i is not attached to the "knocking-off" lever k, kas
usual but its end abuts against the side of the same (when used) so that the weft
fork d, 'd can act against the knocking-off lever k, k but the latter can be moved so
as to stop the loom without acting upon the weft fork or upon the taking-up
catches..
The weft fork bracket i, i is carried upon a vertical arm l, fixed at or near one
end of a horizontal shaft h, h which extends across the loom, and upon this shaft is

page_text: also fixed a latch m, m (which lifts one of the catches n, n³ carried by the
"monkey-tail" lever o, o) and also the retaining catch p, p which holds the
quadrant q q.
This may be effected by means of a snug n* (see Fig. 3) upon the catch ŉ (which
works the quadrant) under which the said latch m, m passes. The retaining
catch p, p being immediately above the catch n may be lifted by the raising of the
latter.
According to this arrangement it will be seen that the quadrant q, q and the
taking-up ratchet wheel c, c are at the same side of the loom, and the apparatus
can thus be applied in a simpler and more economical manner than when
applied as described in the Specification of the Letters Patent before mentioned at
the same time that the weaver can, if he desires make use of the knocking-off
lever k, k (when employed) or the ordinary stopping handle k*, k* for stopping the
loom by hand without interfering with either the weft-fork motion, or with the
taking up or retaining catches.
The action of the apparatus is as follows:-
When the weft breaks or is otherwise absent the weft fork d, d by means of the
bracket i, i pushes back the "knocking-off" lever (when used) to stop the loom and
the vertical arm 1, which carries the bracket i, i is also pushed back causing the
horizontal shaft h, h to rock or make a partial revolution; the latch m, m which is
fast at the end of this shaft h, h is raised and lifts the catch n on the monkey tail
lever o, o and also the retaining catch of the quadrant q, q. This quadrant being
heavier on one side of its centre or pivot is then free to fall against the adjustable
stop **. A pin or projection 8, 8 on the quadrant q, q lifts the lever f, f and
with it the retaining catch e, e which works in the ordinary ratchet wheel c, c of
the taking up motion.
This wheel c, c is not revolved by the working of the loom when put in motion
again, until the pin or projection has regained the position shown on Fig. 1.
But as soon as the loom starts again, the weft fork d, d, the arm land the
latch m, m resume their former positions and the catches n and p fall into the
teeth of the quadrant and at each beat up of the slay sword the quadrant q, q is
lifted or moved the distance of one tooth from the stop **until the catch n
begins to work upon the plain part of the quadrant which then remains in this
position until the weft breaks again. As soon however as this position is regained
the pin or projection 8, 8 on the quadrant has fallen sufficiently to allow the
lever ff and the retaining catch e, e to return to their former position and the
catch n¹ upon the monkey tail lever o, o is thereupon enabled to work the taking
up ratchet wheel c, c again.
Thus at each stoppage of the loom from the breakage of the weft the revolution
of the taking up ratchet wheel is arrested for a few picks, the number of which is
regulated by the position of the adjustable stop * in the slot of the fixed bracket t,
and thus the formation of thick lines or thin streaks across the woven piece
(known respectively as "bars" and "cracks") is prevented, and a perfect and
automatic piecing or continuation of the woven cloth is ensured.
In some cases (as before mentioned) I propose to dispense with the " knocking
off "lever k, k and to substitute in lieu thereof a cranked lever r, r (see Figs. 2a
and 4) which I fix upon the horizontal shaft h, h (carrying the vertical arm l, l).
When the loom is working the stopping handle kx, k* bears against the point 1 on
the cranked lever r, r, as soon as the weft breaks, or is otherwise absent and the
weft fork d, d moves the vertical arm 1, 1 the horizontal shaft h, h is thereby
caused to rock and, by means of the cranked lever r, r, remove the stopping
handle k*, k from the ordinary notch in the framework a¹, a¹ and thus stop the
loom as usual.
The stopping lever k*, k* then alides into the recess 2 on the cranked lever r, r
and locks the shaft h, h the latch m, m and the catches n¹ and p in the raised
position until the lever k*, k* is replaced by the weaver.

page_text: When the loom is stopped without the weft breaking, the stopping handle simply
springs against the projection 3 on the cranked lever r, r without being engaged in
the recess 2.
I would here remark that this cranked lever may be used in conjunction with
other means of acting upon the taking up ratchet wheel when the weft breaks
wherein a rod or shaft is used passing across the loom and actuated by, the weft
fork.
With reference to the locking of the stopping lever k*, k* it is necessary (or at
least preferable) to provide for such locking also when the cranked lever r, r is not
used for stopping the loom.
This may be effected by mounting a locking arm on the shaft h, h somewhat
similar in form to the cranked lever r, r but not provided with the abutment
marked 1. 1. so that when the weft breaks the lever k*, k* may engage with the
locking arm which will hold up the latch m, m and the catches n¹ and p as before
explained.
Or a spring latch or latches may be provided of any suitable form to rest against
the vertical arm l, and lock the motion when the weft breaks.
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
First. Mounting the weft fork bracket in the "taking-up" motion of looms so
that its end abuts against the side of the knocking-off lever and so that it can
oscillate on a horizontal rocking shaft (the action of which dispenses with the use
of a trigger rod or trigger) one end of which carries a curved lever or latch which
acts upon the taking up catches, in order that the "knocking-off" lever can be
moved so as to stop the loom without acting upon the weft fork or the taking-up
catches.
Secondly. Mounting the ratchet quadrant and the taking up wheel and its
catches both at the same side of the loom.
Thirdly. Dispensing with the knocking-off lever and substituting in place
thereof a cranked lever mounted near one end of the horizontal rocking shaft:
all substantially as hereinbefore particularly described and illustrated by the
drawings annexed.
