page_text: Improvements in Looms for Weaving Crimped Fabrics.
1, THOMAS MASON, of Alkincoats, Colne, in the County of Lancaster, 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:-
This invention relates to novel and useful improvements in looms for weaving fabrics
composed of alternate plain and crimped stripes, and its object is to feed the warp
forming the crimped portion of such fabrics with more regularity and precision than
hitherto.
For this purpose I employ a supplementary warp beam to hold the warp forming
the crimped portion of the fabric. The warp is drawn off such supplementary beau
by a drawing-off roller, round which the warp is guided by means of suitable guide
and friction rollers. The said warp drawing-off roller is connected by. change wheels
to a pulley driven by a belt or other means from a pulley on the arbor of the feed-
roller of the take-up motion. A suitable device is provided for connecting or
disconnecting the pulley attached to the take-up motion in order to facilitate the
removal of the woven fabric. And provision is also made for readily altering or
connecting and disconnecting the change gearing actuating the said drawing-off
roller.
In order to describe my invention more in detail, reference is to be had to the
accompanying drawing forming a part of this specification, in which similar letters of
reference indicate corresponding parts in all the figures.
Figure 1, is a side elevation of such parts of a loom as are necessary to illustrate
my invention. Figure 2, is a plan of the same.
The supplementary beam A, holding the warp B, forming the crimped portion of
the fabric, is mounted in standards C fixed to the top of the loom frame D, and the
said warp passes from such beam beneath the friction or pressure roller E, round
the drawing-off roller F, and over the guide roller G into the weaving mechanism of
the loom.
The warp forming the plain portion of the fabric is wrapped upon the beam H, and
is fed or let-off in the ordinary manner.
The drawing-off roller F draws the warp off the beam A, and feeds it into the loom.
The said drawing-off roller is driven from the feed roller I of the take-up motion by
means of the strap J connecting the pulley K, on the arbor L of the feed roller I, to
the pulley M secured to the toothed wheel N mounted on the stud O fixed to the loom
frame. The wheel N engages with an intermediate wheel P mounted on a stud Q
fixed in the slot R formed in the bracket S supporting the drawing-off roller F, the
friction or pressure roller E and guide roller G. The intermediate wheel P engages
the change wheel T on the arbor Ü of the drawing-off roller F.
It will be seen that a larger or smaller wheel may be substituted for the change
wheel T, and that the stud on which the intermediate wheel P is mounted is capable

page_text: of adjustment in the slot R, thus to alter the relative speed of the rollers F and I for
the purpose of regulating the feed of the warp B, a different change wheel is mounted
on the arbor U and the wheel P is adjusted to engage therewith. And it will also be
seen that loosening the set screw V, which fixes the pulley K to the arbor L permits
the feed roller I to be independently rotated in order to facilitate the removal of the
woven fabric or to regulate the tension of the warp B.
The rollers W, W are employed to guide the strap J clear of the weaving
mechanism, and the said strap is twisted at Y so as to drive the roller F in the
direction of its arrow in figure 1.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed, I declare what I claim is :
1. In a Loom for weaving crimped fabrics, the combination with a supplementary
beam, of a drawing-off roller driven from the feed roller of the take-up motion,
substantially as herein shown and described.
2. The combination with the said drawing-off roller, of the friction or pressure
roller E, and guide roller G, substantially as herein shown and described and for the
purpose specified.
3. The combination with the said drawing-off roller, of the change wheel T, inter-
mediate wheel P, and toothed wheel N, substantially as herein shown and described
and for the purpose specified.
