PROVISIONAL SPECIFICATION.
An Improved Method of Dressing or Beaming Warps for Looms.
We,
JAMES LISTER and RICHARD LISTER both of Aireworth Mills Keighley,
in the County of York Manufacturers, do hereby declare the nature of this
invention to be as follows:-
This invention has for its object, the dividing or dressing of warp threads prior
to weaving the same into a fabric, by the automatic division of the threads in a
simple and efficient manner by apparatus so arranged that we are enabled to dispense
with the brushes or other rubbing instruments hitherto used for dividing the warp
threads, and retain the major portion of the size deposited on the warp threads
thereby preserving the strength and wearing qualities of the warp.
"
We accomplish our object in the following manner: The warp threads are
conducted over bars and rollers as hitherto, but instead of the threads passing
direct through a reed to a rotating beam or roller, they pass through mails or loops
in healds or the like operated in a manner that a "shed' is formed by one portion
of the warp threads descending and the other portion ascending some distance
for dividing the threads which on returning, meet in the centre, but by preference
not crossing each other.
The separation by the rising and falling healds or the like is continued so long
as the before mentioned beam or roller rotates, thus by the continued reciprocating
and dividing motion imparted to the warp threads, they are separated without the
intervention of a brush or other rubbing instrument, which as is well known, in
addition to separating the warp threads, remove the size therefrom, thereby reducing
the strength of the warp and wearing qualities.

COMPLETE SPECIFICATION.
An Improved Method of Dressing or Beaming Warps for Looms.
We, JAMES LISTER and RICHARD LISTER, both of Aireworth Mills, Keighley,
in the County of York, Manufacturers, 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 has for its object, the dividing or dressing of warp threads prior
to weaving the same into a fabric, in an automatic, simple and efficient manner, by
apparatus so arranged that, we are enabled to dispense with brushes or other
rubbing instruments hitherto used for the purpose of dividing the warp threads,
and retain the major portion of the size deposited on the warp threads, thereby
preserving the strength and weaving qualities of the warp threads.
In describing our invention in detail, reference is made to the accompanying
drawings, in which
Fig. 1 represents a side view of a warp dressing frame arranged according to our
invention, a portion of the centre upright is cut away to more clearly show the
apparatus.
Fig. 2 a view of the operating mechanism looking in the direction of the arrow
in Fig. 1.

page_text: Fig. 3 a similar view showing the healds, and
Figs. 4. 5. 6. and 7. details hereinafter referred to.
The beam A. upon which the dressed warp threads W. are wound, is mounted in
any convenient manner between the uprights B. B. and driven from shaft C.
by pullies D. D¹ and spur gearing E. in the manner common to warp dressing 5
frames, to which no claim is made as forming part of this invention.
The ball W of warp threads is formed and sized in the usual manner, and the
threads W. are conducted over bars F. and F¹ and roller. G. as hitherto, but
instead of the warp threads W. going direct to the rotating beam A. and
mechanically or otherwise brushed between the roller G. and beam A. for the l
purpose of dividing the threads, they pass through mails or loops M. in the healds H.
or the like which are reciprocated in a continuous and suitable manner, so that,
a "shed" is repeatedly formed by one portion of the warp threads descending and
the other portion ascending some distance, by which repeated operation the said
threads are divided.
1
The reciprocation of the healds H. and warp threads W. may be accomplished by.
securing to the rotating shaft C. a crank J. and coupling same by a rod K. to an,
arm L. mounted loosely upon the shaft N. upon which may be secured the
pullies O, to the circumference of each of which is attached a flexible strap'P. such
as leather, the ends being suitably connected to the healds H. which are kept in 2
tension by a similar arrangement of straps and pullies, the latter being supported
by cross rail T. or the like.
Upon the shaft N. is secured a quadrant U. shown by detail Fig. 4 and is
prepared with two recesses U and U' with either of which a sliding bar V.
mounted in arm L. may engage, so that, by the oscillation of the arm L. the 2
quadrant U. is operated and the shaft N. rocked in its bearings, thus giving a
reciprocating motion to the healds H. and warp threads W. by which the latter are.
automatically and repeatedly divided or separated as they are travelling between.
the roller G. and fixed reed R. through which they pass to the rotating beam A.
the warp threads being, by, preference, kept divided close to the reed R. by a rod S. 3
passing between the threads for the entire width of the warp.
The projection on the bar V. engaging in one of the recesses in quadrant U.
may be changed from one recess U₁ or U to the other, by pressing the lever X.
hinged at X towards the arm Q. of said quadrant; an extension of the lever at X'
engaging between projections on the before mentioned bar V. causes the projecting 3
piece at top of bar to be raised clear of the notch in quadrant, thus liberating
the shaft N. that it may be turned by the quadrant until the projection engages
with the other recess in quadrant.
By changing the position of the projection on bar Vin quadrant U. the motion
transmitted to the healds is reversed, that is to say, those warp threads that formed 4
the top portion of the "shed" now form the bottom, and the bottom threads the top.
of the "shed," the reciprocating warp threads, by preference, meeting in the centre
and not crossing each other.
In place of securing concentric pullies O. on the shaft N. we may accomplish our
object by securing to the said shaft two or more pullies Y. such as shown by elevation 4
and plan Figs. 5 and 6. A leather strap such as P. is secured to each pulley ·
and connected to the healds in a suitable manner; the pullies Z. shown by Fig. 7-
are supported by a stationary crank shaft Z¹ secured to brackets which may be:
attached to the cross bar T. or like support.
By adapting pullies of this class the bealds H. are not close together and are all 5
raised about the same distance, thus putting an equal tension on all the warp.
threads.
The rising and falling motion imparted to the healds H. is continuous so long as
the beam A. rotates, thereby continuously dividing or separating the warp threads
from each other without the intervention of a brush or other rubbing instrument, 5
which as is well known, in addition to separating the threads, removes the size.
therefrom, thereby reducing the strength and weaving qualities of the warp..

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
olaim is :-
1. The hereinbefore described method of dressing or preparing warps for weaving.
The essential novelty consisting in conducting the partly divided warp threads to
the roller G. or equivalent and passing the threads through mails or the like
in reciprocating healds M. and through a reed R. to a rotating beam A. substantially
in the manner indicated.
い
2. The method of dressing warp threads by interposing between the guide
roller G. and rotating warp beam A. of recíprocating healds H. and reed R.
arranged and operated substantially in the manner shown and described.
