PROVISIONAL SPECIFICATION.
Improvements in the Shedding Motions of Looms for Weaving.
I, JAMES TAYLOR, of 5. Millar Barn Lane, Georges Row, Waterfoot, near
Manchester, in the County of Lancaster, Engine Fitter, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in the shedding mechanism of looms for
weaving, the object being to dispense with the healds and healds staves hereto-
fore employed, and to substitute in lieu thereof, rods or rollers, around which
the warp threads are passed, and by means of which the shed is opened and
closed.
According to this my invention, I dispense with the healds, heald staves, and
connections as heretofore employed, and substitute in lieu thereof two, three, or
more rods or rollers, which are actuated by chain and gear from treadles on the
tappet shaft of the loom.
Each warp passes from the warp beam, to and partly around one of the lower
rods or rollers, thence partly around a rod or roller above the first mentioned one,
and between the rods or rollers, the warp is crossed or formed in a single knot or
loop.
When the loom is in motion, by operating the rods or rollers, the knots or loops
are moved nearer to the top or bottom rods or rollers, and the warps are raised or
lowered, and the shed opened and closed.
A presser roller is employed in contact with one of the rods or rollers, to put
tension on the warp threads, and to cause the knots or loops to rise or fall on the
rods or rollers are rocked or rotated.

Improvements in the Shedding Motions of Looms for Weaving.
I, JAMES TAYLOR, of 5 Millar Barn Lane, Georges Row, Waterfoot near
Manchester, in the County of Lancaster, Engine Fitter, 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 improvements in the shedding mechanism of looms for
weaving, the object being to dispense with the healds and heald staves hereto-
fore employed, and to substitute in lieu thereof, rods or rollers, around which
the warp threads are passed, and by means of which the shed is opened and
closed.
Such being the nature and object of my said invention, the following is a complete

page_text: description of same, reference being had to the accompanying drawings, in
which
Fig. 1 is a front elevation of the improved shedding motion shewing the rollers
around which the warp threads are passed.
Fig. 2 is an end elevation of Fig. 1 shewing the gearing.
Figs. 3 and 4 are sections through the rollers and shewing the knot or loop.
According to this invention, I dispense with the healds, heald staves and
connections as heretofore employed, and substitute in lieu thereof, two, three, or
more rods or rollers, but preferably two as shewn in the annexed drawings. The
top roller is actuated by a chain 2 and chain wheel 3 from the treadles on the
tappet shaft of the loom. The lower roller 4 is driven by means of toothed
gearing 5 (see Fig. 2) from the roller 1. Each warp 6 passes from the warp beam
to and partly around the lower roller 4 (see Figs. 3 and 4), thence partly around
the top roller 1 and between the two rollers 1 and 4 the warp is crossed or formed
in a single knot or loop 7. When the loom is in motion and the rods or rollers 1
and 4 are operated, the knots or loops 7 are moved nearer to the top or bottom rod
or roller respectively, and the warps 6 are raised or lowered, and the shed is formed
and opened and closed. On one end of the lower roller 4 are formed teeth 8 which
.gear with teeth 9 on a presser roller 10 mounted in slots 11 in the frame 12. The
presser roller 10 works in contact with the roller 4 and is employed for putting
tension on the warp threads 6 and causes the knots or loops 7 to rise and fall as
the rollers 1 and 4 are rocked or rotated. The roller 10 is kept in contact with
the rod or roller 4 by springs or weights.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
(1.) The general construction, arrangement, and combination of parts constituting
the improved shedding motion, as and for the purpose herein described and sub-
stantially as illustrated by Figs. 1 and 2 of the annexed drawings.
(2.) A shedding motion consisting of two rollers or rods partly around which the
warp threads are passed, and between which such threads are crossed, looped, or
tied in single knots, the said rods or rollers also being caused to revolve first in one
direction and then in the other..
