Weft Threads of Looms in which several Shuttles are Used.
We JAMES BAIRSTOW, Manufacturer, JOHN BAIRSTOW SPENCER, Manufacturer,
and STEPHEN MIDGLEY, Joiner, all of Sutton Mill, Cross Hills via Leeds, Yorkshire,
do hereby declare the nature of this invention to be as follows
This invention has for its object the proper retention of the inoperative weft threads
of looms in which several shuttles are used, so that the damage done to the work
when these become entangled one with another, is avoided.
We attain this by making an appropriately shaped hollow or groove in that end of
the slayboard of the loom on which are mounted the revolving or rising and falling
shuttle boxes, and should this be on both sides of the loom (forming what is commonly
known as pick and pick looms) this hollow will be formed on both sides; so that when
the slay has driven in the threads of weft and is returning for another thread to be
thrown across, the former weft thread will fall and remain within the hollow or groove
until its shuttle is again brought into position and thrown or picked across; and not
become entangled with the other weft threads and be partly dragged into the
piece or shed of warp as is often the case, causing damage as is well understood
in practice.
As will be seen our invention is applicable to both classes of looms, that is revolving
as well as rising and falling or "drop" box looms, for in the former, whether the
shuttle box is turned to or from the front of the loom, the inoperative weft threads, or
weft threads from those shuttles thus turned, are received in the groove; and in the
latter all the threads of those shuttles that fall below the slayboard or out of position
downwards, will be received in the groove as before said, while when these same are
raised upwards out of position from being picked then the threads are taken with them
and require no groove or other means of retention.
If it is thought desirable to further separate the inoperative weft threads, that is,
from each other, we purpose extending the box or using a suitable number of arms to
revolve in an appropriate manner on the outer end of the slayboard between it and
the shuttle box so that as each inoperative thread is received within the groove an arm
shall be turned to separate it from the next that shall be again received.

Weft Threads of Looms in which several Shuttles are Used.
We, JAMES BAIRSTOW and JOHN BAIRSTOW SPENCER, Manufacturers, and STEPHEN
MIDGLEY, Joiner, all of Sutton Mill, Crosshills, via Leeds, Yorkshire 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 inventions relates to looms for weaving and has for its object the proper
retention of the inoperative weft threads in the class of looms where several shuttles
are used, so that the damage done to the work by these becoming entangled one with
another, is avoided.
The accompanying drawings illustrative of this invention shew a portion of the slay-
board of a loom and the common and necessary other parts in connection with
it all unnecessary parts being omitted.
Fig. 1 is a view as seen from above. Fig. 2 is a front elevation. Fig. 3 is a
section to illustrate the hollow in the slayboard. Fig. 4 is a section shewing the shuttle
box and the parts in connection with it. Figs. 5 and 6 are drawings of separate parts
referred to hereafter.
The drawings only illustrate our invention in connection with a revolving box loom
but from the following description it will easily be understood how same may be
applied to a rising and falling or drop box loom.
The object set forth is attained by making a hollow grove A of a suitable shape,
in the end of the slayboard B on which the revolving or drop box is mounted, so
that when the slay has beaten home the weft D and has returned for the purpose of
allowing another thread to be thrown across; the said weft D will be received within
the hollow A where it will remain until its shuttle E is again brought into position
and thrown across, so that the damage done to the work being performed, by the
inoperative weft threads being dragged into the piece or shed of warp, or by same
being worn or cut with the shuttle of the operating weft thread passing over them is
prevented.
In connection with a revolving shuttle box, as all the inoperative weft threads are
from shuttles that are beneath the surface of the slayboard over which the operating
shuttle has to pass, they are easily received and retained in the grove or hollow A, in
whether direction said revolving box may be turned. And in connection with a falling
or drop box, all the inoperative weft threads that are from shuttles beneath the surface
as above described, are received within the hollow or grove A while those above said
surfaces are held in proper position without additional means.
The inoperative weft threads may be more effectually separated by attaching
arms F, as shewn by figs. 5 and 6, to the revolving or circular box G, said arms F

page_text: projecting from said box G towards the end of the slayboard so that as each shuttle
enters the box G, one or another of said arms F lays hold of the weft from it when
the box G is turned to bring another shuttle into position.
The bolt H which is of common use, is bent as shewn by fig. 4 so as not to
interfere with the utility of the grove A.
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. A slayboard having a hollow A made in the end thereof as herein shewn, for the
reception of inoperative weft threads as described.
2. A revolving shuttle box G, with projecting arms F formed thereon, used in
connection with a slayboard having a hollow A as and for the purposes herein
described and declared.
