IMPROVEMENTS IN WEAVING TERRY FABRICS AND IN APPARATUS EMPLOYED FOR SUCH PURPOSE
Year: 1885

page_text: I WILLIAM WARRINGTON of Fairfield Mills Droylsden in the County of Lancaster
Manager do hereby declare the nature of my invention for "IMPROVEMENTS IN
WEAVING TERRY FABRICS AND IN APPARATUS EMPLOYED FOR SUCH PURPOSE 15 to
be as follows:-
The object of this invention is to weave in a loom with a fixed or fast reed,
striped, spotted or other fancy terry fabrics, which I effect by a number of bent
wires or fingers attached to a transverse bar which extends across the fabric a
short distance in front of the line where the weft is beaten up.
In addition to the ordinary warp for weaving the body of the cloth I employ a
terry warp which is wound upon a separate beam and is drawn in through a
separate shaft or heald, and through the reed in stripes or groups.
This shaft is actuated by a tappet higher than those which work the ordinary
shafts so. that when the terry loops are intended to be formed the terry warp
threads are raised well up above the ground warp threads.
Whilst they are in this position the bent wires or fingers are moved back
towards the reed, between the stripes or groups of terry warp; they are then
moved (say) to the left to throw the bent wires or fingers under the terry warp
and then moved forward again towards the cloth so as to throw the terry warp up
into loops, the terry shaft at the same time descending and carrying down the
terry warp below all the other warp. The ground warp is then shed in the usual
manner and the required number of binding picks of weft thrown in. The bent
wires or fingers are then moved back again to (say) the right so as to withdraw
from the loops or terry warp.
The terry warp is then again raised and the operation is repeated as long as
the terry pattern is required.
In weaving spots or other detached patterns the terry warp is floated loosely
over the back from one spot or pattern to the other, and it may be left in this
state or be cut or shorn away as may be desired.
It will be perceived from the above description that a quadruple motion is
required to be given to the transverse bar to which the bent wires or fingers are
attached; this I effect by a combination of a to-and-fro and a lateral motion.

page_text: The transverse bar is attached by brackets to another sliding bar underneath
the cloth and this bar is mounted and actuated in a similar manner to the "sliding
locking bar' mentioned and described in the Specification of former Letters
Patent granted to me dated March 13th A.D. 1884, N° 4806, that is to say the
endwise movement is produced by means of a bowl working on the tappet chain
carried by a vertical slide which is provided with an inclined plane at the top.
This inclined plane acts against a bowl carried by the sliding bar and moves the
latter in a longitudinal direction; the return movement being produced by means
of a spring. The to and fro movement from front to back and vice versa, is
produced by the same tappet which works the terry heald. This tappet comes
against a lever the other end of which is connected by a bell crank to the bar
which carries the bent wires or fingers, and by this combined motion the
quadruple or square motion is given to the said fingers.

I WILLIAM WARRINGTON of Fairfield Mills Droylsden in the County of Lancaster
do hereby declare the nature of my invention for IMPROVEMENTS IN WEAVING
TERRY FABRICS AND IN APPARATUS EMPLOYED FOR SUCH PURPOSE 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 weave in a loom with a fixed or fast reed,
striped, spotted or other fancy terry fabrics, which I effect by a number of bent
wires or fingers attached to a transverse bar, which extends across the fabric a
short distance in front of the line where the weft is beaten up.
In addition to the ordinary warp for weaving the body of the cloth, I employ a
terry warp which is wound upon a separate beam and is drawn-in through a
separate shaft or heald and through the reed in stripes.or groups.
The apparatus which I propose to employ for the purpose of actuating the bent.
wires or fingers and the healds or shafts for "shedding" the terry warp will be
readily understood on reference to the annexed drawings and the following
explanation thereof.
Fig. 1 on the drawing is a transverse vertical section and Fig. 2. a front elevation
of so much of a power loom as is necessary to illustrate my invention.-a, a is
part of the framing of the loom, b, b the crank shaft, c, c the ordinary tappet
shaft, d, d the ordinary warp beam, e, e the terry warp beam, f, f (Fig. 1.) the
healds for shedding the ordinary or ground warp threads, f¹, f¹, and gg t
for shedding the terry warp g', g¹.
the heald
The tappet shaft h, h which actuates the terry warp heald g, g by means of the
treadle or lever i i is situated on a cross shaft k, k driven from the ordinary
tappet shaft c, o by means of bevil gearing 1, 1, and is so arranged that when the
terry loops are intended to be formed, the terry warp threads g¹, g' are raised
well up above the ground warp threads f¹, fl as shown at Fig. 1.
m, m are the bent wires or fingers which are attached or fixed to a bar n, n
carried by two brackets o, o fixed on a transverse rocking bar p, p.
Whilst the terry warp threads g¹, g¹ are in the raised position the bent wires or
fingers m, m.are moved back towards the reed between the stripes or groups of
terry warp, the bar n, n is then moved (say) to the left to throw the bent wires
or fingers m m under the terry warp, and then moved forward again towards the
cloth so as to throw the terry warp g³, g¹ up into loops, the terry shaft or heald g, g
at the same time descending and carrying down the terry warp g¹ g¹ below all the
ground warp threads f¹, f.
The ground warp f₁, f¹ is then "shed" in the usual manner and the required
number of binding picks of weft are thrown in.
The bent wires or fingers m, m are then moved back again to (say) the right so
as to withdraw from the loops of terry warp.
The terry warp g', g¹ is then again raised and the operation is repeated as long
as the terry pattern is required.

page_text: In weaving spots or other detached patterns the terry warp is floated loosely
over the back from one spot or pattern to the other, and it may be left in this
state, or be cut or shorn away as may be desired.
It will be seen from the above description that a quadruple motion is required
to be given to the transverse bar p, p carrying the bar n, n to which the bent
wires or fingers m, m are attached.
This I effect by a combination of a to and fro and a lateral motion.
The bar n, n is attached by brackets q, q to another sliding bar r, r underneath
the cloth and this bar r, r is mounted and actuated in a similar manner to the
"sliding locking bar" mentioned and described in the Specification of former
Letters Patent granted to me dated March 13th A.D. 1884, No 4806, that is to say
the end wise motion is produced by means of a bowl 8, 8 (Fig. 1) working on the
tappet chain t, t and carried by a vertical slide u, u which is provided with an
inclined plane at the top. This inclined plane (as in the former case) acts against
a bowl carried by the sliding bar r, r and moves the latter in a longitudinal
direction; the return movement being produced by a spring.
b
The to-and-fro movement from front to back and vice versâ is produced by a
pin v, on the same tappet h, h which works the terry heald.
This tappet pin v, v acts against a projection w¹, w¹ from a lever w, w jointed to
the treadle i, i and the end of this lever w, w comes against a long cranked
lever, which is connected by an adjustable link y, y and lever 2, 'to the
rocking bar p, p which carries the bent wires or fingers n, n, and by this combined
motion the quadruple or "square" movement is given to the said fingers."
In order to raise the points of the fingers m, m clear of the surface of the warp
as they move backwards I employ at each end a link 1. 1. attached to the
brackets q, q and carrying a pin 2, sliding in a slightly inclined slot 3, (Fig. 1.) so
as to raise the finger bar n, n slightly as it is moved backwards and lower it again
as it returns.
I would here remark that I am aware that bent wires or fingers having a
somewhat similar movement have been employed in the manufacture of "coach'
lace" and therefore I lay no claim to the employment of such bent wires or fingers
per se for the manufacture of looped or terry fabrics excepting when used in the
manner and actuated by the mechanism herein described.
Having now particularly described and ascertained the nature of my said,
invention and in what manner the same is to be performed I declare that what
I claim is :-
1 :
First. The weaving of spotted or other fancy terry fabrics in the manner. and
by the means herein before described and
Secondly. I claim the construction and use of the improved mechanism herein-
before described and illustrated by the drawings annexed for weaving such terry
fabrics.
