page_text: I, CHRISTOPHER TURNER, of 10, Barlow Street, Rawtenstall, in the County of
Lancaster, Joiner and loom slay maker, 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:-
4
This invention relates to the improved construction of, and arrangements connected
with the "reed case " and "stop rod" of loose reed looms; so that, during the
locking action, the reed case will be enabled to close up to the reed with greater
efficiency, and more regularity and uniformity, than in other arrangements: this
combination can also be adapted to, and utilised in looms, of either new or old con
struction; and my improvements are specially directed to, and designed, so that a
loose reed may attain the firmness, and give the regularity to each pick of the weft;
as in a loom in which a fast reed is used; and to so construct a reed case, that a
loose reed loom will weave any strength of cloth, that can be woven in a fast reed
loom; and also to simplify, and reduce the number of parts by which the said objects
are attained.
In order that the nature of my invention may be fully understood, I will refer to
the accompanying sheet of drawings, wherein Fig. 1, represents an elevation, Fig. 2,
a plan, Fig. 3, a cross section, Fig. 4, a back elevation of one end, and Fig. 5, is an
end view to show a method of keeping the reed case up to the reed, and in which the
dotted portion "p" is the loom frame. Figs. 1 and 2 are broken in the middle, the
right hand portion showing the combination, as attached to new looms, and the left
hand portion showing it attached to old looms. Only so much of a loom is shown as
is necessary to illustrate the principle of the invention
» (
In my invention I mount the said "reed case 'a," of suitable section (preferably
of tee iron) on two strong "duck bills" "b, b," of suitable design, one at each end of
the reed case only. Instead of constructing a continuous "stop rod," with its
attendant mechanism, finger pieces and brackets or supports, and the said rod
extending across the full width of the loom, I carry the two duck bills-b, b, upon two
short stop rods, studs centres or fixings "c, c," the said stop rods being carried in
suitable bearings, as shown at "d, d," and I either secure the said duck bills to the
stop rods with set screws e,
e," keys, or pins; or let the duck bills work loose on
the short stop rods, and secure the stop rods as the aforesaid duck bills are secured.

By constructing the mechanism as set forth, and making the reed case
a, a," and
duck bills "b, b," of suitable strength, and extending the backs of the said duck bills
so that they may be firmly attached to the reed case by two bolts in each, as shown
at "f" (Fig. 4); I find that in practice the reed case is brought up to the reed at
an uniform pressure throughout its entire length.

At each end of the reed case «
a, a," a portion of the flange is cut away on one side,
the length of the backs of the duck bills at "g" in Fig. 4. The "slay swords" "o, o,"
to which the slay "," is fixed, have a reciprocating motion, and at the back or end
of the stroke, or traverse of the loom slay "r," the reed" ," has a tendency to tilt,
or fall over somewhat; in consequence of the reed case "a, a," rebounding, or leaving
the reed, and getting out of position. To prevent this tilting, I supersede what is now
used, and known as the "bow spring" and " organ handle," by attaching to the stop
rod c," a suitable lever or projection "," as shown in Figs. 1 and 5, which lever ""
slides on to, and is in contact with the bent lever "j," when the loom swords".
are at the back, and for a sufficient duration of the traverse of them and the slay "r.
The bent lever "," is supported on a suitable fulcrum fixing "k," which is attached
to the slay sword "o," in a suitable manner. A spring " is attached, one end to
the bent lever "j," and the other to the loom frame; so as to keep the lever "j," in a
suitable position. By attaching to the loom. frame " p," a stud or finger "m at a
suitable point, the bent lever "will come in contact with and be held from supporting
the lever "," during a portion of the traverse the loom slay "," and thus allow the
reed case "
a," and the reed "q," to be free to move or fall, if required.

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 use of a reed case supported only at each end without intermediate
bearings and wings.
2. The use of two short stop rods, studs, or centres "c, c," attached to or cast
on the loom slay swords to carry the duck bills "b, b."
3. The use of the levers "h and "j" in conjunction with the spring
and the stud "m" as and for the purposes set forth, and shown on the accom-
panying drawing.
con-
4. The combination of a reed case a "with the duck bills "b, b," mounted
on the short stop rods, studs, centres or fixings "c, c," as described, and
structed and acting substantially as and for the purposes set forth and indicated
hereinbefore, and in and by the accompanying drawing.
