Improvements relating to the Take-up Motions of Looms for
Weaving.
We, WILLIAM HOLDEN and JOSEPH HOLDEN, Cotton Manufacturers, both of
Alexandra Mill, Crawshawbooth, in the County of Lancaster, do hereby declare the
nature of this invention to be as follows:-
This invention relates to the improved construction of and arrangements
connected with the stopping and starting of looms for weaving, so that, when the
loom stops, the cloth or textile piece being woven may be allowed to run back off
the cloth roller in frout of the loom, in the direction of the reed from whence it has
come, a certain automatically fixed distance or amount, instead of being regulated
by the weaver as at present, so that, when the loom re-starts the pick or thread of
weft is inserted nearer to the previous pick or thread than is now the case, thus
preventing a thin or thick place being made in the cloth or piece and therefore
causing the same to be more even, that is, the individual threads or weft being more
equally placed alongside each other when the loom re-starts after the thread or weft
having been broken.
In order that the nature of our said invention may be fully understood, we will
refer to the accompanying sheet of drawing, whereon so much of a part end
elevation of a loom is shown as will illustrate the said invention. In our invention
the new parts introduced on the loom are the slotted lever or pawl A with screw
for regulating the stroke or traverse and the stud or pin B carrying the lever,
B being attached to the frame or end of the loom; the extension lever piece C.
and the pin or finger D extending inwards or towards the loom frame E and
engaging with the lever piece C; or the parts C and D may each be made in a
piece with or part of the existing levers F and G.
An existing train of spur wheels of which only the pitch lines are shown by dotted
circles L on the drawing connect the ratchet wheel J with the sand or emery roller M
over which the cloth passes before being wound on the cloth roller N is shown as
used on an ordinary calico loom.
By constructing the mechanism as set forth and regulating the positions of same
we find that upon the thread or weft breaking, and the lever F being raised by the
partial rotating of the finger rod H, the lever piece C engages with finger D thus
both F and G being disengaged from ratchet wheel J it partially revolves back in
the direction of the arrow → and thus the strain on the cloth or piece being
removed the piece runs back towards the reed at K a fixed amount, by the bottom.
end of the slotted portion of lever A coming in contact with B. The cloth or piece
thus going back in the direction of the reed at K brings the last inserted pick or
thread of weft nearer the position which will be taken up by the pick or thread of
weft which will be inserted in the piece when the loom restarts thus preventing a
thin or thick place, or the weft on loom re-starting being distributed over a longer
length of the piece.

Improvements relating to the Take-up Motions of Looms for
Weaving.
We WILLIAM HOLDEN and JOSEPH HOLDEN, Cotton Manufacturers, both of
Alexandra Mill, Crawshawbooth in the County of Lancaster, 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 relates to the improved construction of and arrangements
connected with the stopping and starting of looms for weaving, so that, when the
loom stops, the cloth or textile piece being woven may be allowed to run back off
the cloth roller in front of the loom in the direction of the reed from whence it has
come, a certain automatically fixed distance, instead of being regulated by the
weaver as at present, so that, when the loom re-starts, the pick or thread of weft
is inserted nearer to the previous pick or thread than is now the case, thus
preventing a thin or thick place being made in the cloth or piece, and therefore
causing the same to be more even; that is, the individual threads or weft being
more equally placed alongside each other, when the loom re-starts, after the thread
or weft has been broken.
In order that the nature of our said invention may be fully understood we will
refer to the accompanying sheets of drawings, two in number, whereon so much
of a part end elevation and plan of a loom is shown as will illustrate the said
invention.
In our invention the new parts introduced on the loom are, the lever or pawl A,
sliding in the jaw piece A', which has a screw for regulating the stroke or traverse
of A, and the stud or pin B, carrying the jaw piece A', the stud or pin B and the
lever piece C are attached to the existing lever F on the finger rod H by the
bolt D, and the new slotted lever piece C, the end of which, extends outwards or
away from the loom frame E and engages with the existing lever piece G to
raise same.
3.
By constructing the mechanism as set forth and regulating the positions of same
we find that, upon the thread or weft breaking, and the lever F and its extension C
being raised by the partial rotation of the finger rod H, the end of the lever
piece C engages with the lever G, thus both C & G being disengaged from ratchet
wheel J it partially revolves back in the direction of the arrow and thus the strain
on the cloth or piece being removed, the piece runs back towards the reed at Ka
fixed amount, regulated by the end of the sliding pawl A coming in contact with
the regulating screw in the jaw piece at A'. The cloth or piece thus going back
again towards the reed at K brings the last inserted pick or thread of weft nearer
the position which will be taken up by the pick or thread of weft next inserted in
the piece when the loom re-starts, thus preventing a thin or thick place,,or the weft
on the loom re-starting being distributed over a longer length of the piece.
An existing train of spur wheels, of which only the dotted pitch lines are shown
by circles L on Sheet 1, connecting the ratchet wheel J with the sand or emery
roller M over which the cloth passes before being wound on the cloth roller N is
shown as used on an ordinary calico loom.
Having now particularly described 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 lever or pawl A. together with the jaw piece A" and its regulating
screw.
2. The stud or pin B'for carrying same.
3. The slotted lever piece C.
4. The combination of the parts A. A¹ and screw, B and C. constructed and

accompanying drawings, and the general method of operation as set forth in this
Specification.
