PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Terry Fabrics, and in Looms
employed in such Manufacture.
I WILLIAM WARRINGTON of Fairfield Mills Droylsden in the County of
Lancaster, Manager do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to produce new effects upon woven fabrics known
as terry fabrics which are pile fabrics the pile of which is formed of loops of the
warp threads thrown up either in patterns on the surface or surfaces of the fabric, or
all over the same.
My invention consists in so graduating or varying the length of the said loops or
terry, that graduated or raised effects can be produced in the terry itself in stripes
across the piece.
To effect this I employ a loose reed arrangement constructed somewhat in the
manner described in the Specification of Letters Patent No. 4806 granted to
myself and dated the 13th day of March 1884 but I so modify the form of the
unlocking projection on the sliding bar which locks or unlocks the reed, and also
the motion of the said sliding bar, that the loose reed may be unlocked to a varying
extent as required thereby varying the beat up so as to form different lengths in
the terry or loops of warp.
The form of the unlocking projection is modified by inclining or otherwise
graduating the height thereof in the direction of its sliding motion so that at
various points different lifts can be given to the lever which unlocks the loose reed
accordingly to the length of the motion imparted to the sliding bar which is or may
be actuated as follows.
32
I use a pattern chain (as described in the above named Specification) but I mount
the bowl which rests thereon upon one end of a cranked lever the other end of
which acts upon a projection from the sliding locking bar above named. The
"risers of the pattern chain can be varied in height so that the sliding motion of
the locking bar can be varied and the unlocking lever of the loose reed will come
into contact with the inclined or graduated projection above described at different
points and so form different lengths of terry.
The projection against which the cranked lever above named works is made to
slide through the locking bar so that it can be withdrawn from contact with the
said cranked lever when it is desired to weave plain cloth by means of a collar or
other device on the said projection moved by a spring lever or fork and the handle
which holds the reed locked when weaving plain cloth is connected to a sliding rod
cranked or provided with an incline acting against the said spring lever or fork to
withdraw the said projection.

Improvements in the Manufacture of Terry Fabrics, and in Looms
employed in such Manufacture.
I WILLIAM WARRINGTON of Fairfield Mills Droylsden in the County of
Lancaster, Manager, 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 :-
The object of this invention is to produce new effects upon woven fabrics known
as "terry fabrics which are pile fabrics the pile of which is formed of loops of the
warp threads thrown up, either in patterns on the surface, or surfaces of the fabric
or all over the same.
My invention consists principally in so graduating or varying the length of the
said loops or terry that graduated or raised effects can be produced in the terry
itself in stripes across the piece.
The nature of my invention and the manner in which the same is to be performed
or carried into practical effect will be readily understood on reference to the annexed
sheet of drawings and the following explanation thereof.
Fig. 1 on the annexed drawing is a front view of so much of a
65 terry or loose
reed power loom as is necessary to illustrate the application of my invention
thereto and
Fig. 2 is a plan view (partly in section) of part of my improved apparatus.
Fig. 3 is a detached section of a part thereof (hereinafter more particularly
referred to) drawn to an enlarged scale.
Fig. 1 is a diagram shewing a piece of terry fabric with loops of various length.
For the purposes of my present invention I employ a loose reed arrangement
constructed somewhat in the manner described in the Specification of Letters
Patent No. 4806 granted to myself and dated the 13th day of March 1884 but I so
modify the form of the unlocking projection a (see detached enlarged view Fig. 3)
on the sliding bar b which locks or unlocks the reed, and also the motion of the said
sliding bar b, that the loose reed may be unlocked to a varying extent as required,
thereby varying the "beat-up" of the reed so as to form different lengths in the
"terry or loops of warp, as shown on the diagram Fig. 14.
The form of the unlocking projection a is modified by inclining or otherwise
graduating the height thereof at the top (as at a¹) in the direction of its sliding
motion so that at various points different "lifts" can be given to the lever which
unlocks the loose reed according to the length of the motion imparted to the sliding
bar which is, or may be, actuated as follows:
I use a pattern chain d (as described in the above named Specification) but I mount
the bowle which rests thereon upon one arm of a cranked lever the other arm of
which acts upon a projection or pin g from the sliding locking-barb above named.
The "risers of the pattern chain d can be varied in height so that the sliding
motion of the locking bar & can be varied and the unlocking lever of the loose reed
will come into contact with the inclined or graduated projection a, a¹ above described
at different points of elevation and so form different lengths of terry according
to the pattern of the chain.
The projection g (see Fig. 2) against which the arm 1 of the cranked lever
above referred to works is made to slide through the locking bar b so that it can be
withdrawn from contact with the said cranked lever when it is desired to weave
plain cloth, by means of a collar g' or other device on the said projection or pin
actuated by a spring lever or fork h. In the drawing the projection g is a ferrule
or bush sliding on a pin g.see Fig. 2.
The handle which usually holds the reed in the locked position when weaving
plain cloth is not required for this purpose as the spring locks the reed when the
lever does not actuate the locking bar b.

page_text: This handle is connected to the sliding rod k which is cranked as shown
at k (Fig. 1) or is provided with an incline acting against the spring lever h to
withdraw the projection out of the way of the cranked lever, when the said
handle is moved into the position for weaving plain cloth.
This handle still causes the taking-up-catch to be raised by bringing the
arm m into position to be acted upon by the projection or plate m' which I fix to
the lever so that when the bowl e is lowered the projection or plate m' is raised.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
First. The improvement in terry fabrics consisting in weaving them with loops
or terry of graduated or varied lengths in continuous or broken stripes across the
piece whereby novel and pleasing effects can be produced as hereinbefore
described.
Secondly claim the arrangement of mechanism substantially as hercinbefore
described and illustrated by the drawings annexed whereby I am enabled to weave
the terry or looped pile on such fabrics of graduated or varied lengths by varying
the length of the "beat-up :: as described.
