Improvements in Dhootie Weaving.
I, HENRY BROOKS BROADHURST, of Tenacres Mill, Newton Heath, Manchester,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
The improvements relate to what is known as dhootie or dhoota weaving, and have
for object the weaving of cloth with borders having different wefts to that which
serves for the central portion of the fabric. And yet to weave in the wefts at the two
horders and at the centro all at the same pick or motion of the loom. To accomplish
this and to effect my improvements I provide three shuttles, one for the central part
and one for each border, but outside or beyond such central portion.
The warps of the central part are arranged to form their own shed at one level,
which is the normal one; while the warps of the borders are arranged to form sheds
at a lower level beyond each edge of the centre.
The tops of the border sheds are arranged in line with the bottom of the centre shed
so that the shuttle for the centre warps is always thrown over the border warps.
These latter are provided each with a separate shuttle, by preference smaller, and
have a correspondingly short throw given thereto, and always pass underneath the
central warps. By which means two borders and one centre are woven as it were
independently side by side at two different levels. I provide certain warp threads
which may be called catch threads, at the points of junction of the border warps and
the centre warps, which catch threads are capable of being alternately operated in the
upper and lower sheds and so interweave a short distance with both the border and
centre warps, thus binding the separate weavings together.
The shuttles and "race "for the horders or lower sheds may either bo fly shuttles,
rack and pinion driven, or other forms of shuttles, and three separate weft forks may
be employed or not; and other variations in detail may be made without departing
from the peculiar character of the invention.

COMPLETE SPECIFICATION.
Improvements in Dhootie Weaving.
I, HENRY BROOKS BROADHURST, of Tenacres Mill, Newton Heath, Manchester,
Manufacturer, 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 :—
The improvements relate to what is known as dhootie or dhoota weaving, and have
for object the weaving of cloth with borders having different wefts to that which
serves for the central portion of the fabric, and yet to weave in the wefts at the two
borders and at the centre, all at the same pick or motion of the loom. To accomplish
this and to effect my improvements, I provide three shuttles, one for the central part
and one for each border, but outside or beyond such central portion.
The warps of the central part are arranged to form their own shed at one level,
which is the normal one; while the warps of the borders are arranged to form sheds
at a lower level, beyond each edge of the centre.
The tops of the border sheds are arranged in line with the bottom of the centre shed
so that the shuttle for the centre warps is always thrown over the border warps.
These latter are provided each with a separate shuttle, by preference smaller, and

page_text: have a correspondingly short throw given thereto, and always pass underneath the
central warps. By which means, two borders and one centre are woven, as it were
independently, side by side at two different levels. I provide certain warn threads
which may be called "catch threads," at the points of junction of the border warps,
and the centre warps; which catch threads are capable of being alternately operated in
the upper and lower sheds, and so interweave a short distance with both the border
and centre warps, thus binding the separate weavings together.
The shuttles and " race "for the borders or lower sheds may either be fly shuttles,
rack and pinion driven, or other forms of shuttles, and three separate weft forks may
be employed or not; and other variations in detail may be made without departing
from the peculiar character of the invention.
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 shews the arrangement of sheds of warp threads opened by the healds, with
the lathe, the reed, and bearers, and beams, in cross section.
Fig. 2 shews a plan view, and Fig. 3 a front view, of a shuttle suitable for the
border weaving; while Fig. 4 shews a front elevation of the picking arrangement for
such border weaving, and Fig. 5 shews a plan view of a portion of the lathe to which
the small shuttle boxes are attached.
The same letters indicate corresponding parts wherever they occur.
a. a. is the lathe; b. b. are the small shuttle boxes, which are sunk below the
ordinary surface or race of the lathe.
c. c indicates the roed of the loom; while d. d. is the picking rod or stick, and
e. e. the small pickers for actuating the border shuttles.
The ordinary portions of the loom are not shewn, as not being essential to the
proper understanding of the invention.
Six healds are shewn, numbered 1, 2, 3, 4, 5 and 6; but any number of healds
may be employed which may be found desirable.
No. 1 heald is shewn to actuate the warp yarn U, which is one of the border
warps.
No. 3 is shewn to actuate the warp yarn V, which is the alternate border warp in
the same reed.
No. 2 is shewn to actuate the warp yarn W, which is one of the ordinary warps
forming the body, or central portion of the cloth; and No. 4 is shewn to actuate the
warp yarn X, which is the alternate ordinary warp in the same reed as W.
Nos. 5 and 6 are shewn to actuate the warp yarns Y and Z, which form the "catch
threads" for binding the edges of the two fabrics together.
By preference I carry the ordinary warps W, and X, over the back bearer f, to the
main warp beam as in ordinary weaving, while the border warps U and V are carried
under one or more extra bearers g. g. to a warp beam h. h, mounted above; and the
catch threads Y and Z may be carried either over the ordinary bearer as shewn, or
, over a special rest or bearer for the purpose, as may be found convenient.
The picking rods d. d. for actuating the border shuttles are by preference linked
together by the rod or bar i. i. extending from one pair of picking rods operating the
shuttle for one border, to the other pair of picking rods operating the shuttle for the
other border. The picking rods are pivotted or fulcrumed upon a fixed bar or
bearer j. j, at el e¹, and one of them on each side is provided with a leg e³, to which is
attached a strap or band k, which passes over the pulleys l. 1. The other end of this
strap or band is attached to a lever suitably mounted, and actuated by a picking
tappet or cam, fixed on the second motion shaft of the loom, as will be readily
understood.
The border shuttles may be of various shapes; but a suitable one is shewn in the
drawings, wherein m. m. is the body of the shuttle; n. n. the spool for the border
weft, which is place upon the tongue or spindle o. o and retained in position by the

page_text: cross wires p. p. and has tension given to the thread by means of the spiral
spring 9. 9.
The arc or bow r. r. through a small orifice of which the weft thread is passed at r³,
is for the purpose of laying the weft evenly in the shed.
Suitably formed shuttle boxes bb for these border shuttles are fitted into the lathe
or slay, which latter is recessed for their reception. Slots are formed in these shuttle
boxes as 61, 61, through which the arc or bow of the shuttle protrudes; and suitable
shuttle springs t. t. are provided for detaining the shuttle in the box on its arrival.
For the more effectual working of the invention, I provide an extra weft fork for
each of the border shuttles; and to enable these to be operative in stopping the loom,
when any one of the three weft threads break, or give out, I set the border shuttles to
pick always in the opposite direction to that of the main or ground shuttle, forraing
the body or centre of the fabric, and I also set the haminers of the border weft
forks to operate at the contrary pick to that of the hammer operating the main
weft fork.
By this means only one weft thread will pass in front of any weft fork at the pick
or motion when its hammer operates.
I am aware that many previous attempts have been made to weave dhooties with
different wefts in the borders to that which is employed in the main body of the fabric,
prior to this my invention.
In these attempts separate shuttles for the borders have been employed, both at the
same pick as the main shuttle, and at alternate picks therewith, in the former case
making the border shed above the shed of the main warp, and in the latter case
forming alternate sheds with the border warps and main warps at the same level;
but these differ entirely from this my present invention, which mainly consists in
forming the border sheds below the level of the main warp shed, recessing the lathe
or slay to receive such border shed, and shuttle boxes at the lower level, and in the
construction of a suitable shuttle and picking apparatus therefor.
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 weaving of dhooties or fabrics wherein different wefts are employed in the
borders to that of the central portion, by forming sheds for the border warps for the
passage of border shuttles at a lower level than the shed of the main warps, for
the purpose and in manner substantially as herein shewn and described.
2. In looms for weaving dhooties or fabrics wherein different wefts are employed
in the borders to that of the central portion, recessed or lower races and shuttle boxes,
formed in the lathe or slay, for the borders, with the picking apparatus actuating
suitable shuttles, for the purpose and in manner substantially as herein shewn and
described.
