IMPROVEMENTS IN APPLIANCES TO LOOMS FOR WEAVING FOR MAKING FRETS OR GALLS IN HEADINGS IN WEAVING COTTON OR OTHER FABRICS
Year: 1885

page_text: I WILLIAM THOMPSON, of Park Bridge Mill, Blackburn, in the County of
Lancaster, Cotton Manufacturer, do hereby declare the nature of my said
invention for " IMPROVEMENTS IN APPLIANCES TO LOOMS FOR WEAVING FOR
MAKING FRETS OR GALLS IN HEADINGS IN WEAVING COTTON OR OTHER FABRICS".
to be as follows:-
66
Heretofore when putting in or weaving the "frets" or galls" in the heading
of cotton or other pieces the practise has been for the weaver to turn by hand the
gear of the taking up motion so as to take up a required length of yarn and then
the shot of weft are put in, and again more warp taken up and weft shot until the
heading is completed.
According to this my said invention, I employ improved mechanism which
dispenses with the hand manipulation of the taking up motion-In front of the
loom near the stop handle is a cranked finger lever the inner end of which extends
to and by a second lever depresses the segmental end of a third and vertical lever
until teeth of the segment gear with a pinion wheel upon a cross shaft extending
to and on the other end of which is a pinion gearing with the spur wheel of the
taking up motion.
The segmental vertical lever is mounted upon a fulcrum stud and a pin connected
to the slay sword is passed through a slot in the said lever so that such lever
receives through the motion of the slay sword a rapid oscillating or reciprocating
motion and when depressed so as to gear with its pinion au accelerated motion is
given to the cross shaft and taking up gear drawing off the required length of
warp, whereon the fret or gall weft is shot and again more warp let off until the
required pattern of fret or gall is produced.
To facilitate mounting the catch wheel upon the cross shaft a short length of
shaft or gudgeon is employed and passed from the outside of the loom frame into
the boss of the catch wheel and by keys or locking pieces formed in the boss of
the catch wheel is attached thereto.

Fabrics.
I WILLIAM THOMPSON, of Park Bridge Mill, Blackburn, in the County of
Lancaster, Cotton Manufacturer, do hereby declare the nature of my said
invention for "IMPROVEMENTS IN APPLIANCES TO LOOMS FOR WEAVING FOR
MAKING FRETS OR GALLS IN HEADINGS IN WEAVING COTTON OR OTHER FABRICS
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
"
"
Heretofore when putting in or weaving the "frets or "galls" in the heading
of cotton or other pieces, the practise has been for the weaver to turn by hand the
gear of the taking up motion so as to take up a required length-of yarn and then
the shots of weft are put in, and again more warp taken up and weft shot until
the heading is completed.
Such being the nature and object of my said invention, the following is &
complete description of same, reference being had to the accompanying drawings
forming a part of this specification in which :-
:
Fig. 1 is an end elevation of loom with my improvements applied.
Fig. 2 is an end elevation in section of loom during ordinary working with my
improvements applied.
Figs. 3 and 4 are also end elevations in section of loom during ordinary
working with my improvements applied-Fig. 3 shewing position of levers ready
for an extra take up to form a gall and Fig. 4 position of levers after taking up to
form a gall.
Fig. 5 is a plan.
Figs. 6 and 7 sectional and side elevations of existing catch wheel shewing
method of securing shaft and gudgeon.
According to this my said invention I employ improved mechanism which
dispenses with the hand manipulation of the taking up motion-In front of the
loom near the stop handle is a cranked finger lever 1, the inner end 2 of which
extends to and by a second lever 3 depresses the end 4 of the segmental lever 5
mounted on a stud in the vertical lever 6 until teeth of the segment 7 clear the
pinion wheel 8 upon a cross shaft 9 extending to and on the other end of which is
a pinion 10 gearing with a spur wheel 11 of the taking up motion.
The segmental and vertical levers 5, 6, are mounted upon a fulcrum stud 12,
and a pin 13 connected to the slay sword 14 is passed through a slot 15 in the
said lever 6 so that such lever receives through the motion of the slay sword 14
a rapid oscillating or reciprocating motion and when depressed by the lever 1
being moved on its fulcrum pin as shewn at Fig. 3, the lever 3 allows the teeth of
the weighted or segmental lever 5 to gear with its pinion 8, an accelerated motion
is given to the cross shaft 9 and taking up gear drawing off the required length of
warp whereon the fret or gall weft is shot and again more warp let off until the
required pattern of fret or gall is produced.

page_text: To facilitate mounting the catch wheel upon the cross shaft 9 a short length of
shaft or gudgeon 16 is employed and passed from the outside of the loom frame 17
into the boss of the catch wheel 18 and by keys or locking pieces 19 and
recesses 20 as shewn at Figs. 6 and 7 formed in the boss of the catch wheel 18 is
attached to the shaft 9.
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
The cranked lever 1, lever 3, segment lever 5, vertical lever 6, pinion wheel 8,
cross shaft 9, catch wheel 18, locking devices 19, 20, all in combination for purposes
herein described and substantially as illustrated by the annexed drawings.
Dated this 5th day of February 1886.
