I, ELIJAH NUTTER, Gentleman, of Eccleshill, near Bradford, in the
County of York, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows, that is to say :— .
My Invention relates, firstly, to employing a vertical loom instead
of the horizontal loom now in use, thus enabling the weaver to see
at once the various beams, healds, warps, and all connected with the
fabrics, and is designed not only to weave textile fabrics, but also wire
fabrics. This loom in making narrow fabrics produces double the work
by each revolution of the shaft with safety and speed compared with
looms now in use.
My Invention relates, secondly, to the use of a weft carrier and
concealed shuttle; this weft carrier is made flat or round of steel or any
other hard substance, pointed at the end where it enters the shed or
division of the warp threads, having a hole near the point, and another
at a suitable distance; through these holes the weft passes from a cop

page_text: above it, the cop may be of large size, even 12 inches in diameter, and in
proportionate length and is fixed above the loom. The weft carrier is
moved through the shed or division of threads by means of a lever which
is operated upon by a cam, an eccentric, or any other suitable gear, and
passes over the reed and through the threads without touching it, thus
doing away with friction. When the weft carrier has passed a short
distance beyond the warps on the opposite side the concealed shuttle
passes over it and through the weft of the carrier and in the space or
opening produced from the weft at the nose of the carrier to its
connection with the fabric above; the weft carrier then retreats to its
former position, and a connection is secured between the weft of the
carrier and weft of the shuttle. The sley performs its accustomed
operation in driving up the weft producing a perfect selvage and fabric.
The shuttle being concealed in a box during its operation prevents the
shuttle flying out, and to enable the removal of the shuttle with facility
part of the apparatus and box employed in working the shuttle are
made moveable and easily lifted in order that the shuttle may be taken
out.
My Invention relates, thirdly, to making and using healds made entirely
of steel or of any other properly tempered metal, and are a substitute for
cotton, worsted, or wire healds. These healds are separated one from
the other allowing sufficient space for the threads, and the whole are
capable of adjusting themselves to a coarser or finer reed saving the
introduction of fresh healds at every change. These metal healds are
fixed in frames, and at each end are fixed small friction pullies which
move on iron plates by means of levers, spring, and cam, or by means
now in use, thus allowing metal healds moving horizontally to be prac-
tically used, doing away with the presont objections of their weight and
the difficulty of threading them. The weft carrier and concealed shuttle
can be applied to looms now in use.
