PROVISIONAL SPECIFICATION.
Improvements connected with the Taking-up Mechanism of Looms
for Weaving.
I, EDWARD HOLLINGWORTH, of the firm of Hutchinson Hollingworth and
Company Limited, of Dobcross, Yorkshire, Power Loom Makers, do hereby declara
the nature of this invention to be as follows:-
My invention has reference to Hollingworth and Knowles' fast running looms,
but the improvements are applicable to other descriptions of looms, the primary object
of my invention being to couple or connect the Jacquard reversing gear with the
taking up gear, so that when the Jacquard is reversed for the purpose of lagging or
pulling back or other causes, the rotary motion of the cloth beam is also to be
reversed in the same degree, or proportion, by which means, when the weaving is
resumed, the fabric will be equally woven or wefted.
In applying my invention to Hollingworth and Knowles loom I fix a peg or
other suitable form of wheel on the end of the horizontal shaft specially used for
reversing the motion of the Jacquard pattern cylinder; I also place anoilier peg or
toothed wheel in connection with the gear of the taking up motion, the two peg wheels
being connected together by an endless chain, strap, or rope, so that when the shaft
is operated for reversing the Jacquard pattern cylinder, the motion of the said shaft
is communicated by the intermediate chain to the cloth beam, the effect of which is
to reverse the said cloth beam so as to compensate for the amount of had or broken
weft which has been removed in the process of lagging or pulling back.
Instead of coupling the taking up mechanism with the horizontal reversing shaft
by means of a chain or belt as already described, the two parts may be coupled
together by an upright shaft, or other mechanical equivalent may be employed for
the same purpose; and instead of coupling the taking up motion with the horizontal
reversing shaft of the Jacquard, such taking up motion may be coupled to some other
convenient part of the said Jacquard.
By connecting or coupling the taking up gear with the Jacquard reversing gear as
herein set forth, the reverse action of the Jacquard mechanism is simultaneously
transmitted to the taking up mechanism.

COMPLETE SPECIFICATION.
Improvements connected with the Taking-up Mechanism of Looms
for Weaving.
I, EDWARD HOLLINGWORTH, of the firm of Hutchinson Hollingworth and
Company Limited, of Dobcross, Yorkshire, Power Loom Makers do hereby declare
the nature of this invention and in what manner the same is to he performed,
to be particularly described and ascertained in and by the following statement :—
My invention has reference to Hollingworth and Knowles' fast running looms,
but the improvements are applicable to other descriptions of Jacquard looms.
the primary object of my invention being to couple or connect the Jacquard reversing
gear with the cloth taking up gear, so that when the Jacquard is reversed for the
purpose of ingging or pulling back or other causes, the rotary motion of the cloth
beam will also be reversed in the same degree or proportion, whilst the " going part"
remains stationary by which means, when the weaving is resumed, the fabric will be
equally woven or wefted.
In order that my invention may be better understood, I will now make reference
TP27

page_text: to the accompanying sheet of Drawings illustrative thereof, wherein Fig. 1 represents
the end elevation of a loom, sufficient to shew the application of my improvements
thereto, and Fig. 2. front elevation thereof. A represents the loom framing, B the
cloth or
taking up beam, on the end of which is a worm wheel C in gear with a
worm D mounted on the horizontal shaft. E connected with the taking up gear F,
which comprises a series of toothed wheels.
i In the Hollingworth and Knowles fast running loom, there is employed a horizontal
shaft, shewn in the drawings by letter G, which shaft in this loom is used for the
purpose of reversing the Jacquard mechanism when lagging or pulling back for the
purpose of finding broken weft or for other causes. When the parts of the Jacquard
mechanism have been reversed and the warp slackened, such operation has hitherto
had no effect upon the cloth beam, consequently the tension on the warp and cloth
was at this time unequal. To maintain unity of tension between the cloth beam and
the warp, a more equally woven or wefted fabric can be produced; therefore in
order to obtain more unison between the cloth beam and the warp, I couple or
connect the Jacquard reversing gear with the taking up gear, and this I effect by
placing on the end of the reversing shaft G a chain wheel H, and in connection with
the taking up gear I use a corresponding chain wheel I, the two wheels being
connected together by the chain, strap, or cord J, so that on the reversing shaft G
being operated in either direction, the motion thereof is communicated to the taking
up gear in exactly the same degree or proportion, whereby the unity of tension is
maintained throughout, so that when the loom has been reversed and the weaving
resumed, it is clear that the fabric will be equally woven or wefted throughout.
By connecting or coupling the taking-up gear with the Jacquard reversing gear as
herein described, the action of the Jacquard mechanism is simultaneously transmitted
to the taking-up mechanism, and these motions are performed whilst the loom proper
remains stationary.
Instead of coupling the taking-up mechanism F with the horizontal reversing
shaft G by means of a chain or belt and cord J as described, the two parts may be
coupled together by an upright shaft and bevel or spur wheels as will be well
understood.
Instead of coupling the taking-up gear with the horizontal reversing shaft of the
Jacquard, such taking up gear may be coupled to so ne other convenient part of the
Jacquard, but preferably in the manner shewn in the Drawings.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed. I declare that what I
claim is:
1
The employment of mechanism substantially as herein shewn and described, for
coupling or connecting together the Jacquard mechanism with the cloth taking up
mechanism of looms for weaving in manner and for purposes as described.
