CHARLES SMITH, of Burnley, in the County of Lancaster, Mechanic, " IMPROVE-
MENTS IN LOOMS FOR WEAVING."
The first part of my Invention relates more particularly to the arrangement and
construction of a vertical loom. I place the taking up and letting off motions one
above the other, in such manner that the warp threads will be extended in a
perpendicular or vertical position in the loom. The healds move to and fro
horizontally by cams or tappits and levers, and to keep the cloth distended whilst
being woven I use the well known revolving temples. I cause the slay to rise
and fall by means of cranks or cams for the purpose of beating in the weft. The
throw of the shuttle is effected by levers and tappits. The mechanism for stopping
the loom on the absence or breakage of the weft is similar to the weft motion now
in use. By this part of my Invention the space now required for the loom will be
greatly reduced, and also allow greater facility to the weaver in piecing broken
ends. The second part of my Invention has for its object the weaving off of the
bottoms of cops.
For this purpose I place on the shank end of the shuttle peg a
light hollow tube, so that when the cop is broached on the peg the bottom portion
thereof will be upon the hollow tube above mentioned. A pin or other projection is
secured near the bottom of the peg in such position that when the weft has been
woven or paid off the peg sufficiently, the weft will be caught upon the pin or
other projection; the remaining portion of the cop will now be compelled to revolve
with the hollow tube, thereby weaving off the whole of the cop. The third part
of my Invention consists in improvements in the mechanism for actuating or
picking the shuttles across the shed. I place on each side of the crank shaft a spur
or toothed wheel which gear into other wheels supported by studs on the framing
of the loom; on the face of the latter wheels I fix or otherwise secure a nose bit
or projection for the purpose of striking the picking sticks, thus propelling the
shuttle across the shed. The said picking sticks are supported and allowed to turn
freely upon studs fixed at the back of the loon, and are kept in contact with the
wheels and nose bits by springs; or a grooved cam may be used as a medium
for throwing the shuttle, a provision being made so as to allow a larger or smaller
nose bit to be used as may be required. This part of my Invention is equally
applicable for under or over pick looms. The fourth part of my Invention relates
го

page_text: more particularly to improvements in loose reed looms, and consists essentially in a
novel arrangement of levers for locking the reed, the said levers being centered or
pivoted at the front of the slay. The extremities of these levers are inclined or
bevelled so as to hold the reed firmly in position during the beat up of the weft.
The fifth part of my Invention consists in casting the body portion of weft forks
to the prongs or wires, the prongs or wires being flattened at the ends to which
they are secured to the body portion whilst being cast in the mould. The shank
or hooked portion may be likewise secured to the boss in casting.
