Improvements in Looms for Weaving Crimp Cloths.
We, THOMAS MASON LIMITED, Cotton Manufacturers, WILLIAM NUTTER
STANSFIELD, Clerk, and JOHN ALDERSLY, Foreman Overlooker, all of Primet
Mills, Colne, in the County of Lancaster, 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 :-
Our invention relates to looms having two or more warp beams, in which the
yarn from one beam is taken up into the fabric in excess of that of the other
as in weaving terry and crimp cloths.
Our invention consists essentially in the employment and application of a rod to
the back bearer of the loom, the said rod being bent at its ends, so as to stand a
little off, when secured by set screws or the like to the back bearer or rest; and
the invention also consists in passing the yarn from the upper warp beam under
the said rod, and then under and over the respective lease rods to the
healds. The lower or ground warp is passed over the back bearer in the usual
manner.
The rocking motion of the back bearer is imparted to the said fixed rod, which
in its movement with the back bearer must necessarily take a longer radius, since
it stands further from the point of oscillation. Consequently the warp is drawn
from the top beam in excess of the lower beam, and crimp cloth of good quality
is produced in this simple and efficient manuer. The crimping can be regulated
to any degree by weighting the upper beam.
In the accompanying drawings,
Fig. 1 is a sectional detached view, and
Fig. 2 a detached-back view of a loom side with our invention applied.
A is the improved rod or crimper bent at each end, and secured by set screw B.
to the back bearer or rest C. The upper warp beam D is supported by upright
or standard E, and the warp therefrom is carried under the said rod or crimper A..
The warp from lower beam G is carried as usual over back bearer C.
It will be evident that the rocking or oscillatory motion given to the rod or
crimper A will be greater than that given to the back bearer C, since its distance.
from the point of oscillation is greater, and in consequence the warp from the upper
warp beam will be delivered into the fabric in excess of the lower warp, whereby
crimp cloth is produced. The delivery of the warp from the upper beam may be
regulated to a nicety by the employment of suspended weight W.
A modification of our invention is represented in Fig. 3, the crimping being here
produced by the variation in the delivery of warps, passed over reciprocatory and
stationary back rests respectively. In this view, the rod A. is dispensed with, and
the warp from the upper warp beam D is carried under a separate and independent
rocking back bearer B¹. The lower warp G is carried over the back rest H,
fixed by bolts to the loom side.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The arrangement of apparatus for producing crimp cloth, substantially as
described and illustrated in Figs. 1 and 2.
2. The rod A constructed as shewn, and fixed to back bearer C, the upper warp
being passed under the said rod A, substantially as described and shewn for the
purpose set forth.

page_text: 3. The modification represented in Fig. 3 consisting of reciprocatory and
stationary back rests for causing a variation in the delivery of the respective warps,
substantially as described and illustrated.
Dated this 13th day of April 1894.
