We, JOHN MASON, of 63 Hopwood Street, Preston, in the County of Lancaster,
Weaving Manager, and JONATHAN JUMP, of 84 Barton Terrace, in the same town,
Mill Mechanic, do hereby declare the nature of this invention to be as follows:-
This invention has for its object the "taking up" of the cloth in a loom in a reliable
or positive manner by means of apparatus in which the emery roller speed required
for different classes of cloth to be woven may be imparted with exact reference to the
number of picks to be produced in a given length. On one end of the emery roller
shaft we mount a toothed wheel which is rotated through an intermediate carrier wheel
and a detachable change wheel from a pinion on the end of a shaft driven from the
tappet shaft through a cross shaft and worin gearing. The intermediate carrier wheel
has an extended boss on which the change wheel is fastened, the change wheel
gearing into the pinion and rotating with the carrier wheel on the same axis.
We arrange the number of teeth on the wheels and pinion and their speed of
rotation relatively to the surface speed of the emery roller so that the change wheel
may have the same number of teeth as there are picks to be put in the cloth in a given
length, preferably of half an inch. Upon the end of the tappet shaft we mount a
worm gearing into a worm wheel fast upon the cross shaft which extends to the front
of the loom, the outer extremity of the cross shaft being provided with a hand wheel
by which the shafts and gearing may be rotated by hand when the loom is stopped.
The cross shaft is in two lengths and carries a clutch box operated through a pivotted
arm passing up to the weft knocking-off lever above, so that when the weft breaks the
pivotted arm will disengage the clutch and the taking-up motion will be thrown
simultaneously out of gear and thus prevent "weak places "being made in the cloth.

page_text: An Improved Taking-up Motion for Use in Looms for Weaving.
We, JOHN MASON, of 63, Hopwood Street, Preston, in the County of Lancaster,
Weaving Manager, and JONATHAN JUMP, of 84, Barton Terrace, in the same town,
Mill Mechanic, 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 has for its object, the "taking up" of the cloth in a loom in a reliable
or positive manner by means of apparatus in which the emery roller speed required
for different classes of cloth to be woven may be imparted with exact reference to the
number of picks to be produced in a given length.
In the accompanying drawings,
Figs. 1 and 2 are views of opposite ends of so much of a loom as is necessary to
illustrate the nature and application of our said invention. On one end of the emery
roller shaft a we mount a toothed wheel b which is rotated through an intermediate
carrier or pinion wheel c (shown in Fig. 3) and a detachable change wheel d from a
pinion e on the end of a shaft f driven by the tappet shaft g through a cross shaft h
and worm gearing i, j. The intermediate pinion wheel c may have an extended boss
on which the change wheel & may be fastened, the change wheel d gearing into the
pinion e and rotating with the intermediate pinion wheel c on the same axis k.
A convenient arrangement whereby the change wheel d may be readily detached and
re-attached to the intermediate pinion wheel c is shown at Fig. 4 in which the pinion c
is provided on its outer side with two pins or pegs which fit into corresponding holes.
in the inner side of the change wheel d, the two wheels being held together by the
cross pin through a hole in the fixed stud or axis k.
We mount the stud or axis k so as to be adjustable upon a bracket v formed with a
curved slot (concentric with the axis a of the emery roller) through which the stud k
is fastened by a screw nut in the required position according to the varying diameters
of the change wheels from time to time employed.
We arrange the number of teeth on the wheels b and d and pinions cand e and
their speed of rotation relatively to the surface speed of the emery roller / so that the
change wheel & may have the same number of teeth as there are picks to be put in the
cloth in a given length, preferably of half an inch. Upon the end of the tappet
shaft g we mount a worm m gearing into a worm wheel n fast upon the cross shaft h
which extends to the front of the loom, the outer extremity of the cross shaft / being
provided with a hand wheel o by which the shafts h and fand gearing i and j may be
rotated by hand when the loom is stopped through the breaking of the weft. The
cross shaft h is in two lengths (the division being shown in dotted lines at x in Fig. 2)
and carries a sliding clutch box p operated through an arm or lever q pivotted at r
and passing up to the weft knocking-off lever s above (shown in plan view at Fig. 5)
so that when the weft breaks the pivotted arm q will disengage the clutch (by moving
it to the right as shown at Fig. 2) and the taking-up motion being thereby thrown
simultaneously out of gear and thus preventing weak places" being made in the
cloth.
It will be observed that by the above described arrangement the loom whilst in
motion and weft passing through the shed in the ordinary way the clutch p will remain

page_text: locked with the jaws t on the boss of the worm ; that is to say the two portions of the
cross shaft h will be coupled so that the apparatus cannot be wound up by the attendant
when the loom is in motion and so decrease the number of picks per inch put in the
cloth as is frequently done in practice with the ordinary taking up apparatus of looms.
When the loom is stopped however through breakage of the weft and the clutch p
disengaged the worm j worm wheel i and shaft may be turned round by means of
the hand wheel o so as to rotate the wheel gearing at the other end of the loom in
either direction as may be required.
We find a convenient arrangement of gearing for arriving at the required speed of
the emery roller relatively to that of the tappet shaft to consist in making the worm m
with a double pitch screw thread so that the pinion or worm wheel n may be rotated
to the extent of two teeth for each revolution of the worm m.
The worm wheel n we prefer to have 12 teeth, the worm wheel i 30 teeth, the
the pinion e 42 teeth, the intermediate pinion c 36 teeth, and the emery roller wheel
to have teeth in number proportional to the circumference of the emery roller that
is to say, with gearing as above described, if the circumference of the emery roller
be 15 inches the number of teeth in the wheel b should be 120, if 15 inches the
number should be 124 or one tooth to every one eighth of an inch of circumference.
If the worm and other gearing be arranged as above described the number of picks
put in for every half inch of cloth being woven will exactly correspond with the
number of the teeth in the change wheel d. By having the number of teeth stamped
or cast upon one side of the change wheels the correct change wheel for producing the
exact number of picks required for any class of cloth may be readily selected and
applied thus saving time in calculations and experimental tests and overcoming the
difficulty with ordinary arrangements of such apparatus in which it is frequently
impracticable to arrange a train of geared wheels which will produce the precise
number of picks required.
Although we prefer to actuate our apparatus by means of the rotation of the
tappet shaft as above described in conjunction with apparatus for preventing winding
on by hand whilst the loom is in motion other notions in the loom may obviously
be caused to rotate the change wheel gearing arranged as above described.
Having now particularly described and ascertained the nature of the said invention
and in what manner it is to be performed, we declare that what we claim is:
1. In looms for weaving the arrangement of and mode of actuating the toothed
wheels b, c, d, and e, whereby a detachable change wheel having a given number of
teeth causes a similar number of picks to be produced in a given length of cloth
substantially as described and shown in the drawing.
2. The construction and arrangement of the cross shaft h and attendant mechanism
whereby the rotation of the emery roller can only be effected by hand when the weft
knocking-off lever is moved and the motion of the loom thereby stopped substantially
as described and shewn in the drawings.
3. The combination of parts constituting the improved taking up motion for use
in looms for weaving constructed arranged and operating substantially as described
and shewn in the drawings for the purpose specified.
