page_text: Improvements in Apparatus for Weaving Fabrics.
I, EDWARD SMITH, of 42, Well Street, in the City of Bradford, Manufacturers
Agent, do hereby declare the nature of this invention to be as follows:-
This invention relates to a certain improvements in weaving looms such as are
described in my Specification No. 20479 of 1897, and has for its object the con-
struction of the conical tube support described in the before named specification,
in such a manner that, the support and conical tube may be placed at some distance
from the edge of the fabric, and by so arranging the said support that, the outer
end of the conical tube is prevented leaving the same should the selvage thread be
broken or exhausted; also to carry or suspend the cop or ball of weft, and provide
a suitable device for adjusting the amount of tension on the weft, and to combine
with the loom, apparatus by which provision is made for enabling various colours
or qualities of weft to be woven into the fabric; and an appliance for taking up the
spare ends of the warp threads automatically.
In carrying out my invention, I form one end of the conical tube holder with
a flange provided with a slot hole through which the selvage thread as it leaves
the conical tube passes, by which arrangement the holder and tube may be placed
at any convenient distance from the edge of the fabric, thereby keeping the edge
of the selvage free, by which a more perfect selvage is obtained as the conical tube
cannot be pulled into contact with the selvage.
I form at the opposite end of the conical tube holder a flange in such a manner
that, the conical tube is retained in the holder should the thread by any means be
broken or become exhausted, and by mounting the conical tube holder upon a
sliding plate, the liability of breakage is reduced should anything come in contact
with the said holder during the beat up of the weft.
The weft is placed on a suitable bracket in a manner that it freely leaves the
cop or ball, and the tension to suit the class of yarn is regulated by a spring,
between which, and some portion of the bracket, the yarn is passed to the shuttle
or weft carrier. By the adjustment of the spring the pressure upon the yarn is
regulated, and by conveying the various colours or qualities of yarn under different
springs, the necessary amount of tension is obtained upon the yarn, conducted
therefrom in any convenient manner to the various shuttles or weft carriers.
In order to take up the spare ends of the warp automatically, I provide a drum
or creel driven by preference by friction, from the flange of the warp beam or other
suitable rotating disc. The spare ends are all conducted to the drum or creel, and
by the latter rotating, they are collected without requiring the attention of the
weaver.

I, EDWARD SMITH, of 42, Well Street, in the City of Bradford, Manufacturers
Agent, 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 certain improvements in weaving looms such as are
described in my Specification No. 20479 of 1897, and has for its object, the con-
struction of the conical tube support described in the before named specification,
in such a manner that, the support and conical tube may be placed some distance
from the edge of the fabric, and to so arrange the said support, that the outer end
of the conical tube is prevented leaving the support should the selvage thread be
broken or exhausted; also to carry or suspend the cop or ball of weft in a manner
that, the amount of tension on the weft may be adjusted, and to make provision for
taking up the spare ends of the warp threads automatically.
In describing my invention in detail reference is made to the accompanying
sheet of drawings, in which Fig. 1 represents a plan showing the conical tube and
support fixed some distance from the edge of the fabric.
Fig. 2 is a plan of the support and tube drawn to an enlarged scale.
Fig. 3 is a partial sectional elevation through the conical tube holder.
Fig. 4 is an elevation showing my method of suspending the cop or ball of weft
and the device for adjusting the tension on the weft.
Fig. 5 is an elevation showing certain portions of a loom end and end view of
my warp threads taking up apparatus, and
Fig. 6 an elevation of same.
The bracket A, is secured to the breast beam B, and upon the said bracket is
placed the plate C, of the conical tube holder in a manner that the said plate will
slide on the bracket A, a projection D, is formed on the underside of the bracket A,
on which is placed a spiral spring E, held in tension by the other end of the spring
being coupled to a stud F, secured to the plate C, of the conical tube holder, by
which the said holder is kept in the position shown by Fig. 3, but should anything
come in contact with the end of the conical tube holder at C', say during the beat
up of the lathe, the holder will retreat in the direction of the arrow, and on the
return of the lathe will be brought to its original position by the contraction of
the spiral spring E.
The cup C, of the conical tube holder is provided with a flange C³, at the end
next the selvage of the fabric, for retaining the conical tube T, in position, and
through the said flange a slot hole G, is formed through which the selvage thread
from the conical tube passes; thus by providing the holder with a flange C³, at one
end with a slot hole cut through same, the said holder and tube may be placed at
any convenient distance from the edge of the fabric, and thus keep the edge of the
selvage free, by which a more perfect selvage is obtained, as the conical tube can-
not by any means be pulled into contact with the selvage. A plate H, projects over
the conical tube T, and a flange J, is formed at the expanded end of the said holder
to assist in retaining the conical tube T, within the holder.
The cop or ball of weft K, is placed upon a spindle L, secured to the bracket M,
mounted in any convenient position, the thread or threads of weft K', on leaving
the cop or ball K, pass into the funnel N, and through an opening in the bottom
thereof, then between the spring (), and a pad of suitable material secured to the
support 1.
On the adjustment of the spring (O), by the screw Q, the pressure upon
the weft is regulated, and the necessary tension obtained for allowing the weft to
be distributed by the loom shuttle or weft carrier.

page_text: In order to take up the spare ends of the warp threads W, automatically, the
warp beam R, is mounted in the loom in the ordinary manner, and to the top
rail P, or other support of the loom, I mount brackets S, supporting a shaft S₁,
driven by preference from what is commonly known as the low shaft U, of the loomi
by a belt V, engaging with the pulley X, secured on the shaft S', on which is also
wrapped as the shaft S, and sleeve Y, around with the spare warp threads W, are
wrapped as the shaft S', and sleeve Y, rotate, the wrap threads W, by preference
passing over a roller Z, and a guide as at Z', placed between the warp beam R, and
sleeve Y: on the before mentioned shaft.
It will be readily understood that my spare warp thread collecting apparatus will
be applicable to looms of the ordinary description.
Having now particularly described and ascertained the nature
of my
invention, and in what manner the same is to be performed, I declare that what
I claim is;
-
1. A sliding conical tube holder provided with a flange C³, at one end having
a slot hole G, cut therein, and a flange or projection, at the opposite end, all
arranged and operated substantially in the manner as shown and hereinbefore
described.
2. The combination of the weft holder bracket M, with a funnel N, spring O,
and adjusting screw Q, all arranged substantially in the manner as shown and
described and for the purpose as hereinbefore set forth.
3. A warp beam R, of a loom with which is combined a rotating shaft S', pro-
vided with a detachable sleeve Y, arranged and operated substantially in the
manner as shown and hereinbefore described and for the purpose set forth.
