Manufacturer. "IMPROVEMENTS IN LOOMS FOR WEAVING."
The improvements relate to the weaving of what are known as "dhootas," that
is to say, fabrics having for their central portions grey, plain, or figured cloths, and
for borders a portion varying in width of colored warps and also of colored weft
or wefts for that portion only; and the improvements are also applicable to the
weaving of shawls, handkerchiefs, fringes, or fringed fabrics. Hitherto such goods
have been for the most part woven in India by native workmen, and with
primitive methods. The object of this my present Invention is to weave the same
by means of a power or other automatic loom of the description hereinafter given.
To accomplish this, and to effect my improvements, I actuate the warp threads by
means of jacquard motion, dobbies, or tappet motions in such manner that a shed
is formed for the passing of the ordinary shuttle through the central portions of
the yarn alternately with sheds for the passing of special shuttles through and
formed in the borders, which special shuttles can carry yarn of cotton, or silk, or
wool, or other fibres of any desired color. To enable this to be done a shed is
opened, or the yarn of the warps is divided in the usual manner (excepting that
of the borders), which latter is allowed to lie on the slay board or shuttle race.
The ordinary shuttle is then thrown through this shed so formed, and at the next
motion of the looin these same warp yarns are in turn allowed to lie on the shuttlè
race or slay board, and the border sheds are opened for the passage of the special
shuttles, which special shuttles are actuated in the following manner, viz. :-Shuttle
carriers are formed with spring sides in such manner that when the shuttle is
contained in one carrier, the springs of the same are thereby forced apart, so that
the points of the spring sides of the other carrier can pass between them, and thus
take the shuttle from one carrier to the other alternately. Motion is given to these
carriers by mounting them on suitable arms, or spindles, or guides, connected in
any desired manner to the working parts of the loom. These arms may be single
or double, but are constructed so as to give to the shuttle guides a constant parallel
position relative to the reed of the loom.

The improvements relate to the weaving of what are known as dhootas," that
is to say, fabrics having for their central portions grey, plain, or figured cloths, and
for borders a portion varying in width of coloured warps, and also of coloured weft
or wefts for that portion only; and the improvements are also applicable to the
weaving of shawls, handkerchiefs, fringes, or fringed fabrics. Hitherto such goods
have been for the most part woven in India by native workmen, and with
primitive methods. The object of this my present Invention is to weave the same
by means of power or other automatic looms of the description hereinafter given.
To accomplish this, and to effect my improvements, I actuate the warp threads
by means of jaquard motion, dobbies, or tappet motions in such manner that a
'shed" is formed for the passing of the ordinary shuttle through the central
portions of the yarn alternately with sheds formed in the borders for the passing
of special shuttles through them, which special shuttles can carry yarn of cotton,
or silk, or wool, or other fibres of any desired colour, or gold, silver, or other
metallic threads. To enable this to be done a shed is opened, or the yarn of the
warps is divided in the usual manner, excepting the warp yarns forming the
borders, which latter are allowed to lay on the slay board or shuttle race.
ordinary shuttle is then thrown through this shed so formed, and at the next
motion of the loom the warp yarns forming the body or central portions of the
fabric are in turn allowed to lie on the shuttle race or slay board, and the border
sheds are opened for the passage of the special shuttles aforesaid, which special
shuttles are actuated in the following manner, viz.:-Two shuttle carriers are formed
for each special shuttle with spring sides in such manner that when the shuttle is
contained in the one carrier the springs of the same are thereby forced apart so as
to form a spring holder in such manner that the points of the spring sides of the
other carrier can pass between them, and thus take the shuttle from one carrier to
the other alternately, the shuttles being formed with pointed ends for this purpose.
Motion is given to these carriers by mounting them on suitable arms, or spindles,
or guides connected in any suitable manner to the working parts of the loom.
These arms may be single or double, but are constructed so as to give to the
shuttle guides a constant parallel motion or position relative to the reed of the
loom..
The
But that the improvements may be better understood, I will by the aid of the
accompanying Drawings proceed more fully to describe means employed by me.
DESCRIPTION OF DRAWINGS.
Fig. 1 shows an elevation, and Fig. 2 a plan view of apparatus arranged
according to my improvements. The same letters indicate corresponding parts
wherever they occur. a, a, is a special shuttle held in position by means of the
spring arms, or levers, or holders b, b, attached to the carriers c, c, such carriers c, c,
being fixed by means of pin joints d, d, to the radial arms or levers e, e, which turn
upon studs ff, affixed to a plate or bearing g, g, which is firmly attached to the
breast rail or other convenient portion of the loom. The two pairs of radial arms
or levers e, e, are geared together by gearing or other suitable means, and have
motion communiented to thom he means of the lever and link-rod actuated

page_text: by cam or other motion on the ordinary working parts of the loom; j, j, are stops
whereby the holders b, b, are regulated as to their distance apart, which same
holders may be formed with metallic or other springs behind each lever, or it may
be by constructing the holder simply of suitable springs.
Having now described my improvements and means I adopt in carrying the
same into effect, I would have it understood that I do not confine myself to
the precise details shown & described, as variations may be made without
departing from the peculiar character of the Invention.
But what I do claim is,-
"
The use of shuttle carriers for special shuttles in looms, provided with spring
shuttle holders and fixed on radial arms for the purpose of weaving "dhootas or
other bordered or fancy fabrics, substantially as shown and described.
In witness whereof, I, the said Edwin Smith, have hereunto set my hand and
scal, this Tenth day of August, in the year of our Lord One thousand
eight hundred and eighty one.
