page_text: PROVISIONAL SPECIFICATION.
I THOMAS GRIMSHAW of Witton (near Blackburn) in the County of Lancaster,
Overlooker, do hereby declare the nature of my said Invention for "IMPROVEMENTS
IN LOOMS FOR WEAVING " to be as follows:-
The object of this Invention is to ensure uniform tension or strain on the cloth
during the weaving thereof and to reduce to a minimum tho jerky action
occasioned by the letting off and the healds motions.
According to this my said Invention in combination with the trough and temple
roller and near thereto is a longitudinal groove in length equal to or slightly wider
than the width of the cloth being woven-Within the groove is placod a lath or
bar and the cloth is passed under the said bar on the sides of which and under edge
of which it binds ensuring more even tension and improved finish of cloth.

COMPLETE SPECIFICATION.
I THOMAS GRIMSHAW of Witton (near Blackburn) in the County of Lancaster,
Overlooker do hereby declare the nature of my Invention for "IMPROVEMENTS
IN LOOMS FOR WEAVING" and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement,
aided by the annexed Drawings :—
The object of this Invention is, to ensure uniform tension or strain, on the cloth,
during the weaving thereof, and to reduce to a minimum, the jerky action
occasioned by the letting off, and the heald motions.
According to this my said Invention, in combination with the trough, and temple
roller, and near thereto and forming part of the said trough is a longitudinal
....---

page_text: groove, in length equal to or slightly wider than the width of the cloth being
woven Within the groove is placed a lath or bar roller or rod and the cloth is
passed under the said bar roller or rod on the sides of which and under edgo of
which and on the edges of the trough, it binds, ensuring more even tension, and
improved finish of cloth,
Fig. 1 is an end elevation of the improved apparatus.
Fig. 2 is a plan view,
Fig. 3 is a sectional elevation.
Fig. 4 is plan of roller and tension bar.
and the
At 1 is the trough, so formed as shewn, to carry the temple roller
tension bar 3 the latter at each end, has a foot or resting piece 4, so as to keep
under rounded part 5, of the bar 3, clear of, and above the bottom of its trough 1-
6 is a holding down cap, for temple roller and bar-The trough 1, roller 2, and
bar 3, are carried on the support 7, (one at each side of the loom) after the manner
of carrying the ordinary temple roller, and trough 1-The cloth as woven, passes
as shown by arrows over the edge of the trough at 8, under the temple roller 2,
over edge of trough at 8¹ on which it binds under the tension bar 3, thence to and
over the outer edge of the trough 1 to the breast beam, and to the taking up, and
cloth rollers 9 and 10 as ordinary.
Having now particularly described and ascertained, the nature of my said
Invention, and in what manner the same is to be performed, it will be understood
that the form of the bar 3 trough 1, and its upper edges on which the cloth binds
may be varied without departing from the principle of the Invention and that the
Invention is equally applicable to the use of what are called side templos and that
for the latter a like construction of bar and grooved trough having binding
edoes. 8-8-as-described would be used-
