Improvements in or applicable to Looms for Weaving Terry Fabrics.
We HERBERT HOBSON of Green Lane, Heywood, Lancashire, Foreman with
Messrs. William Smith and Brothers, Limited and WILLIAM SMITH AND
BROTHERS, LIMITED of Sun Ironworks, Heywood, Lancashire, Machine Makers,
do hereby declare the nature of this invention to be as follows:-
Our said invention relates to improvements in or applicable to looms for weaving
terry fabrics such as for example Turkish towels.
The terry or looped part of the fabric is produced by crowding up the terry warp
in the usual way by means of a reed which is made loose or fast as required. With
the reed loose the weft threads or picks to bind the loops are put in but on the beat
up of the slay owing to the reed being loose these weft threads are not driven close
up to the already woven part of the fabric and in consequence an interval is left
the width of which depends on the size of loop it is intended to produce. The reed
when required is rendered fast and on the beat up of the slay the weft threads just
previously put in are driven up close to the already woven cloth and take with
them the terry warp lying in the before mentioned interval. Suitable means for
tightening and relaxing the terry warp are provided.
The required fixing and releasing of the reed is controlled by one or more
oscillating tongues or cam levers secured, to a suitable part of the loom and by bowls
or their equivalents mounted on the end of a lever or combination of levers and
shafts moving with the slay and holding or releasing the reed according as the bowl
or bowls passes under or over the oscillating tongues or cam levers. The oscillating
tongue or cam lever is mounted in a slot or sliding bearing so that the free play of
the reed when loose and consequently the length of the loops may be varied. The
position of the oscillating tongue determines whether the bowl on the reed
controlling lever shall pass under or over the tongue and consequently whether at
any given pick the reed shall be loose or fast. The position of the oscillating
tongue is governed by a chain or the like connection which is raised aud lowered
by the shaft machine or jacquard the cards of which are arranged so as to lift or
lower the oscillating tongue as required to produce the loops.

Our said invention relates to improvements in or applicable to looms for weaving
terry fabrics such as for example Turkish towels.
In order that our said invention may be more clearly understood we will describe
the same with reference to the accompanying drawings in which
Fig. 1 is a side elevation showing the device for fixing and releasing the reed of
a loom for weaving terry fabrics.
Fig. 2 is a sectional elevation of a loom for weaving terry fabrics showing the
invention applied thereto to be hereinafter described.
The terry or looped part of the fabric is produced by crowding up the terry warp
in the usual way by means of a reed which is made loose or fast as required. The
required fixing and releasing of the reed a is controlled by a tongue or cam lever b
oscillating on a pin or bolt secured to the frame c of the loom and having a bowl f
mounted on the end of the lever e which is secured to the shaft d moving with the
slay. The said bowl mounted on the reed controlling lever e fastens or releases.
the reed a according as the bowlf passes under or over the oscillating tongue or
cam lever b. The position of the oscillating tongue or cam lever determines
whether the bowl on the reed controlling lever e shall pass under or over the
tongue and consequently whether at any given pick the reed a shall be loose or fast.
The position of the oscillating tongue b is governed by a cord or other connection
such as a chaing passing over a pulley or pulleys g¹ and connected to a lever h
which is raised and lowered by the shaft machine or jacquard the cards of which
are arranged so as to lift or lower the oscillating tongue 6 as required to produce
the loops. On the cord or chaing being. raised the oscillating tongue or cam
lever bis lifted the reed controlling lever e carrying the bowlf being connected to
the shaft d moves downwards with the slay when the reed a controlled by the
arm on the said shaft d moves back into the position shown in dotted lines at
Fig. 2. The reed a being now loose the weft threads or picks to bind the loops
are put in but on the beat up of the slay owing to the reed a being loose these weft
threads are not driven close up to the already woven part of the fabric and in
consequence an interval is left the width of which depends on the size of loop it is
intended to produce. The reed a is rendered fast by means of the bowlf on the
reed controlling lever e passing over the oscillating tongue b as shown in full lines
at Fig. 2 and on the beat up of the slay the weft threads just previously put in are
driven up close to the already woven cloth and take with them the terry warp lying
in the before mentioned interval.
The plate bolted to the frame c of the loom is provided with a flange or
beading on which rests the end of the oscillating tongue or cam lever b when the
bowl for fastening the reed is moving on the top thereof.
In order to produce different sizes of loops in the fabric the reed controlling
levere carrying the bowlf is provided with a slot and regulating screw e
(Fig. 1) to enable the bowl to be moved forward or backward in the slot e' as
may be required.
Instead of the slot 2 being formed in the reed controlling lever e the loom
frame c may be slotted so as to enable the pin or bolt of the oscillating tongue or
cam lever to be adjusted therein.
The terry warp may be tightened or loosened as required by any suitable
intermittent tension device. For example the terry warp w passing from the warp
beam passes, over a rail mounted on the swinging arm m and connected to the
shaft n. Secured to the said shaft n is a lever o having a bowl, mounted thereon
which engages with the underside of the weighted lever r. Connected to the said
weighted lever r which is fulcrumed at to a bracket t is a rope s or other suitable
tension device passing round a pulley on the warp beam and having one of its
ends connected at s to the loom frame, and the other end connected at to the
weighted lever r. When the terry warp to is drawn tight by means of the reed the
rail over which the warp to passes moves forward in the direction of the arrow y

page_text: the bowl p on the lever o lifts the weighted lever r and the tension devices being
released the terry warp w is slackened.
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
claim is.-
1. The herein before described combination of parts for fixing and releasing the
reed of a loom for weaving terry fabrics substantially as and for the purpose set
forth and shown.
2. In a loom for weaving terry fabrics the combination with a loose reed a of an
oscillating tongue or cam lever b reed controlling lever e moving with the slay and
a connection such as j operated by a shaft machine or the like appliance for
alternately fixing and releasing the reed substantially as and for the purpose set
forth and shown.
