We ROBERT FIELD of Folly Hall, Huddersfield, Yorkshire, Weaver and TOM
GELDER of Lockwood near Huddersfield aforesaid Mechanic do hereby declare the
nature of our invention for "IMPROVEMENTS IN APPARATUS FOR PREVENTING
" TRAILINGS IN" IN LOOMS FOR WEAVING," to be as follows:
This invention relates to drop box Looms, and consists in the employment of
apparatus for preventing the ends of weft which lie between the piece and the
shuttle boxes from becoming entangled one with the other and causing "trailings
in"in the cloth.
In Looms for weaving fancy pieces it is necessary to employ a number of shuttles,
each carrying a different quality or colour of weft in order to produce the desired
pattern. These shuttles work in boxes at each side of the Loom, and arranged one
above the other, as is well understood.
As these boxes rise or fall, one or other of the shuttles is presented (according to
selection by the Jacquard) opposite to the shed, through which it is sent to the
corresponding box on the opposite side of the Loom.
We assume for illustration that there are three shuttles at one side of the Loom,
and as there is a considerable distance between the boxes and the selvedge of the
piece, it follows that there is a similar length of weft hanging between the shuttle
and the selvedge, thus, by a little oscillation or swaying movement of the threads,
they easily become entangled one with the other, consequently, when one of the
shuttles is sent back across the Loom, the other thread or threads are carried along
with it into the piece, thus causing a faulty place or what is known in the trade as
"trailings in."
Our invention is intended to provide means to prevent these "trailings in" and
in order to carry out our invention we place a sliding bar on each side of the Loom
about midway between the piece and the shuttle boxes. At a suitable height on
the rocking frame carring the boxes, we fix a bracket having on one side thereof
a short lever arm to which is attached a small pulley, and on the opposite side of
the bracket is a stud carrying another small pulley. A cord is connected to the

page_text: head piece carrying the rods for raising and lowering the shuttle boxes, such cord
passing under the pulley on the stud and over the pulley on the lever arm, the
other end thereof being connected to the sliding bar which slides in a bracket fixed
to the front part of the running board, the said sliding bar having a number of
booked projections cast thereon corresponding to the number of boxes. A catch is
fixed to the said bracket which takes into notches at the back of the sliding bar
for the purpose of holding such bar until the projection is brought under the weft,
when the catch is released by a projection or piece of bent wire hinged to the
breast beam.
When the Loom is weaving we will assume that one of the shuttles has just
been sent across the Loom, and the next shuttle to be presented is in the bottom
box; the boxes are raised accordingly when the slay beats up, but the sliding bar
being held by the catch previously mentioned, draws down the lever arm until the
catch is released, whereupon the said lever arm draws up the bar to the same height
as the boxes, being assisted by a strong spiral spring.
or
By this means each thread of weft is supported, and entanglement of the ends,
trailings in rendered impossible.
The method of raising or lowering the sliding bar may be varied or altered
according to different classes of Looms employed.

We, ROBERT FIELD of Folly Hall Huddersfield, Yorkshire, Weaver and Toм
GELDER of Lockwood, near Huddersfield aforesaid, Mechanic do hereby declare the
nature of our invention for IMPROVEMENTS IN APPARATUS FOR PREVENTING
"TRAILINGS IN IN LOOMS FOR WEAVING," 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 drop box Looms, and consists in the employment of
apparatus for preventing the ends of weft which lie between the selvage of the
piece and the shuttle boxes from becoming entangled one with the other, and
causing "trailings in" in the cloth.
In looms for weaving fancy pieces it is necessary to employ a number of shuttles
each carrying a different quality or colour of weft in order to produce the desired
pattern.
These shuttles work in boxes at each side of the loom and arranged one above
the other as is well understood.
As these boxes rise or fall, one or other of the shuttles is presented (according to
selection by the Jacquard) opposite to the shed, through which it is sent to the
corresponding box on the opposite side of the Loom.
We assume for illustration that there are three shuttles at one side of the loom,
and as there is a considerable distance between the boxes and the selvedge of the
piece it follows that there is a similar length of weft hanging between the shuttle
and the selvedge-thus, by a little oscillation or swaying movement of the threads,
they easily become entangled one with the other consequently when one of the
shuttles is sent back across the loom, the other thread or threads are carried along
with it into the piece, thus causing a faulty place or what is known in the trade as
trailings in."
Our invention is intended to provide means to prevent these "trailings in" and
in order to carry out our invention we place a sliding bar on each side of the loom
about midway between the piece and the shuttle boxes. At a suitable height on
the rocking frame carrying the boxes we fix a bracket having on one side thereof
a short lever arm to which is attached a small pulley, and on the opposite side of
the bracket is a stud carrying another small pulley. A cord is connected to the
head piece carrying the rods for raising and lowering the shuttle boxes, such cord
passing under the pulley on the stud and over the pulley on the lever arm, the
other end thereof being connected to the sliding bar which slides in a bracket fixed
to the front part of the running board, the said sliding bar having a number of
hooked projections cast thereon corresponding to the number of boxes. A catch

page_text: is fixed to the said bracket which takes into notches at the back of the sliding bar
⚫for the purpose of holding such bar until the projection is brought under the weft,
when the catch is released by a projection or piece of bent wire hinged to the
breast beam.
In order that our invention may be more fully understood we herein make
reference to the accompanying Sheet of Drawings illustrative thereof.
Fig. 1 is front elevation of so much of a loom as is necessary to shew the
application of our improvements thereto, and Fig. 2 is transverse section of part
of Fig. 1.
A is the loom framing, B the lay sword or rocking frame, C the head piece
carrying the rods for raising and lowering the shuttle boxes D; and E is the
running board, all of which are arranged and operated in the usual manner.
To the head piece C we connect one end of a cord a which passes under the
pulley b, carried by a stud on the bracket F attached to the rocking frame; and
over the pulley c on the lever arm G working upon a fixed centre on the bracket F,
the opposite end of such cord being connected to the upper end of a sliding notched
bar H, which slides up and down the slot d in the bracket I, which bracket is
hinged to the running board E by the plate e, a flat spring f being employed to
keep the bracket I against the running board. On the sliding bar H are a number
of hooked projections g. 91 92 9³ corresponding to the number of boxes h, h¹ h³, h³
and which are employed to support the threads of weft which hang between the
selvedge of the piece being woven and the shuttles, for the purpose of preventing
the entanglement of such threads of weft.
Another sliding bar of the same description and with like connections is employed
at the opposite side of the loom to that shewn in the drawings for the same purpose
as will be easily understood.
The mode of operation is as follows; When the boxes are raised or lowered, the
cord à is drawn up or paid out whereby the sliding bar H is raised and lowered
at the same time and to the same extent as the boxes as for instance-if the
boxes are raised so as to present the third box h³ opposite the "shed" as shewn in
the drawings, the cord a being drawn up thereby raises the sliding bar H to the
same extent whereby the thread of weft which is suspended between the selvedge
of the piece and the shuttle is taken hold of and supported by the projection g'.
It will be seen from the drawings that the projection g³ is below the level of the
running board, and does not therefore support the weft, the reason thereof being
that when the slay beats up towards the breast beam K the weft is not over the
projection g and as it does not attain that position until some point between the
extent of the return movement of the slay is reached, the sliding bar H is prevented
from rising to the same height as the boxes until the weft has been brought over
the projection g³ (the depression of the lever arm G allowing for this) by the
catch L which takes into one of the notches i, i, i i³ at the back of the sliding
bar as shewn in dotted line, and holding such bar until the slay reaches a point
between the extent of its return movement, when the catch L is released by the
finger ; working in a guide in the projection M attached to the underside of the
breast beam; whereupon the spiral spring N draws up the lever arm G, and
consequently the sliding bar, whereby the projection g³ takes hold of and supports
the thread of weft.
The lever arm G is prevented from raising the sliding bar too high by coming
into contact with the bolt head K.
It will be understood that when our improvements are applied to fast looms, it
will be necessary to employ a strong spiral spring or its equivalent to draw down
the sliding bar.
By the employment of a sliding bar having projections thereon as shown, and
operating such bar as described, each thread of weft which is suspended between
the shuttle and the selvedge of the piece being woven is supported separately,
whereby entanglement of the ends and " trailings in" are prevented,

page_text: The method of raising or lowering the sliding bar may be varied or altered
according to different makes or classes of Looms to which our improvements are
applied.
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 as our invention is;
Firstly The sliding hooked bar H and parts connected therewith, operated in
manner and for purposes herein set forth.
Secondly-The employment of apparatus substantially as herein shewn and
described for supporting the "ends" or "trailings in
entanglement.
