We, RICHARD GREENWOOD, of The Gables, Blackburn, in the County of
Lancaster, Cotton Manufacturer, and Joux HEATLEY, of Rose Hill Foundry,
Blackburn aforesaid, Clerk, do hereby declare the nature of this invention to be
as follows:-
Our invention relates to improvements in the taking up motion of looms for
weaving and particularly to what is known as the compound taking-up motion.
In this motion there are a pair of intermediate carrier change wheels mounted
upon a single stud placed between the change wheel on the stud which carries
the ratchet wheel and the wheels which transmit the motion from the ratchet
wheel to the wheel on the axle of the taking up roller.
Our first improvement relates to an improved bracket for carrying the stud
upon which this pair of carrier change wheels are fitted and to means for
mounting the pair of carrier change wheels so that they are interchangeable on
the stud and at the same time are connected together in such a way that the
motion given to the driven carrier wheel is transmitted positively to the other
carrier wheel. Our second improvement relates to the oscillating lever which
carries the catch or pawl which gears into the ratchet wheel and our third
improvement relates to the catch or pawl to prevent it moving away from the
ratchet wheel.
According to our first improvement we substitute for the ordinary bracket and
stud, which carries a pair of intermediate change wheels, a forked bracket formed
with two bearings for the stud which is preferably made of two diameters the
longer of which is journalled in one arm of the bracket. The first carrier wheel
is fitted on the reduced diameter of the stud and rests in the fork between the
two bearings and fitted in the bearing in the other arm is a bush, through
which bush the reduced portion of the stud projects and receives the second
carrier wheel which is secured by a nut or otherwise; the bush has a key or
pin projecting from each end which fits into a corresponding key-way or hole
in each carrier wheel and in this manner all the carrier wheels can be utilized
in either position on the stud providing they have a suitable key-way.
As an alternative the stud might be made of the same reduced diameter
throughout and a loose bush be fitted on it in the bearing of the bracket first
referred to in the preceding arrangement.
According to our second improvement in place of pivoting the oscillating lever
which carries the catch or pawl for actuating the ratchet wheel and gearing in
the usual manner we propose to pivot it upon the boss of the bracket which
carries the stud for the ratchet wheel and the ordinary change wheel.
According to our third improvement we make the catch or ratchet pawl with
a flange on its inner side (or upon both sides) which fits over the ratchet wheel
and holds the catch in position and in order to remove the catch it need only

page_text: be raised sufficiently high above the wheel when it can be slipped off its stud
on the oscillating lever.

Improvements in the Taking up Motion of Looms for Weaving.
We, RICHARD GREENWOOD, of The Gäbles, Blackburn, in the County of
Lancaster, Cotton Manufacturer, and Joux HEATLEY, of Rose Hill Foundry,
Blackburn aforesaid, Clerk, 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:-
Our invention relates to improvements in the taking up motion of looms for
weaving and particularly to what is known as the compound taking up motion.
In this motion there are a pair of intermediate carrier change wheels mounted
upon a single stud placed between the change wheel on the stud which carries
the, ratchet wheel and the wheels which transmit the motion from the ratchet
wheel to the wheel on the axle of the taking up roller.
Our first improvement relates to an improved bracket for carrying the stud
upon which this pair of carrier change wheels are fitted and to means for
mounting the pair of carrier change wheels so that they are interchangeable on
the stud and at the same time are connected together in such a way that the
motion given to the driven carrier wheel is transmitted positively to the other
carrier wheel.
Our second improvement relates to the oscillating lever which carries the catch
or pawl which gears into the ratchet wheel, and
Our third improvement relates to the catch or pawl to prevent it moving away
from the ratchet wheel.
According to our first improvement we substitute for the ordinary bracket and
stud, which carries a pair of intermediate change wheels, a forked bracket formed
with two bearings for the stud which is preferably made of two diameters the
larger of which is journalled in one arm of the bracket. The first carrier or change
wheel is fitted on the reduced diameter of the stud and rests in the fork between the
two bearings, and fitted in the bearing in the other arm is a bush, through
which bush the reduced portion of the stud projects and reeeives the second
carrier or change wheel which is secured by a nut or otherwise; the bush has a key
or pin projecting from each end which fits into a corresponding key-way or hole
in each change wheel and in this manner all the change wheels can be utilized
in either position on the stud providing they have a suitable key-way.
According to our second improvement in place of pivoting the oscillating lever
which carries the catch or pawl for actuating the ratchet wheel and gearing in
the usual manner we propose to pivot it upon the boss of the bracket which
carries the stud for the ratchet wheel and the ordinary change wheel.
According to our third improvement we make the catch or ratchet pawl with
a flange on its inner side (or upon both sides) which fits over the ratchet wheel
and holds the catch in position and in order to remove the catch it need only
be raised sufficiently high above the wheel when it can be slipped off its stud
on the oscillating lever.
In the accompanying sheet of drawings-
Figure 1 is a side elevation, and Figure 2 a plan of part of the taking motion
of a loom for weaving to which our improvements are applied.

page_text: Figure 3 is a sectional view of our improved bracket for carrying the inter-
mediate change wheels.
Figures 4 and 5 are detail views of the bush employed in the said bracket.
Figures 6 and 7 are two views of the improved ratchet pawl.
In these views,-1 denotes part of the looin frame and 2 the forked bracket,
which we substitute for the ordinary bracket and stud, and which is secured to
the frame 1 by a bolt 3.
In the two arms of the forked bracket are formed bearings for a bolt or stud 4
made of two diameters the larger of which is journalled in one bearing. The
first change wheel 5 is fitted on the reduced diameter of the stud and rests in the
fork abutting on one side against the shoulder formed by the reduction in
diameter of the stud and on the other side against the other bearing in which is
fitted a bush 6, shown detached in Figs. 4 and 5. The reduced portion of the
stud 4 projects through the bush 6 and receives the second change wheel 7 which
is secured by a nut 8 screwed on to the threaded end of the stud or by any other
convenient device. The bush 6 has a key or pin 9 projecting from each end
and each pin 9 enters a key-way or hole formed to receive it in its corresponding
change wheel as clearly shown in Fig. 3.
In this manner and by these means all the change wheels in the taking up
motion can be utilized in either position on the stud 4 provided that each wheel
has a suitable key-way.
As an alternative, the stud 4 might be of the same reduced diameter throughout
and a loose bush be fitted on it in the other bearing of the bracket.
We prefer to use the forked bracket 2 formed in one piece as shown but we
might employ any other suitable form of bracket or support for the bearings of
the stud 4 and bush G. Again instead of mounting the bush 6 loosely upon
the stud and employing the pins 9 at the ends of the bush we might mount
both the change wheels and the bush upon a feather key in the stud.
The carrier wheels 5 and 7 are intermediate wheels in the usual train of
gearing from the ratchet wheel 10 on the shaft 11 to the gear 12 on the taking up
roller 13 and according to my second improvement we pivot the usual oscillating
taking up lever 14 which carries the ratchet pawl 15 on a boss or part concentric
with the shaft 11, and formed with or carried by the bracket in which the said
shaft is journalled.
We also, according to our third improvement, make the ratchet pawl 15 with
flanges on both sides or on the inside only, and these flanges fit over the ratchet
wheel 10 and so hold the pawl 15 in position. In consequence we can simply
fit the pawl loosely upon a plain stud 16 carried by the oscillating lever 14 and
thereby can remove the pawl 15 at any time by simply lifting it clear of the
ratchet wheel 10 and pulling it off the stud 16.
Either of our improvements may be used separately.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. The first improvement which consists in dispensing with the ordinary
Bracket and stud, which carries a pair of intermediate change wheels, and sub-
stituting a forked bracket carrying the stud 4 formed preferably of two diameters
and carrying the change wheels 5 and 7 having key-ways or holes to receive keys
or pins projecting from the ends of a bush placed between the said wheels sub-
stantially as and for the purposes herein set forth.
2. The combination with the intermediate change wheels 5 and 7 mounted on
a stud such as 4, of the bush 6 mounted loose on the stud and having a pin 9 at
each end for keying the said wheels substantially as and for the purposes herein
set forth.
3. The second improvement which consists in pivoting the oscillating taking
up lever on the same centre and on the same bracket as that of the ratchet wheel

page_text: and in combining with it according to our third improvement, a ratchet pawl 15
provided with a flange on its inner side or on both sides and fitted loosely on a
plain stud 16 carried by the taking up lever substantially as and for the purpose
herein set forth.
4. The general combination and arrangement of parts embodying our several
improvements substantially as herein described and as illustrated by the accom-
panying drawings.
