-
Fabrics.
We, WILLIAM RICHARD GIBBS FAREY, of the firm of Samuel Farey and Son, of
Firth Shed, Skipton, in the County of York, Manufacturer, and ROBERT LANG-
HORNE, of the same address, Mill Manager, do hereby declare the nature of this
Invention to be as follows: —
Our invention relates to improvements in looms for weaving terry and other
looped fabrics and the chief object of our improvements is to simplify and render
positive the motion for letting off or slackening the top warp to produce the loops.
In carrying our improvements into effect we mount in suitable bearings an
additional rod preferably above or near the ordinary top rod by which the heald
shafts are raised and lowered. On this rod we fix two arms or levers one arm con-
nected adjustably to the dobby and the other arm connected by a spring to any
convenient part carries a spring nawl which engages the ratchet wheel
which controls the letting off motion consequently when the additional
rod is moved in its bearings by the connection from the dobby
to one arm it turns the letting off wheel by means of the pawl on the other arm
any required number of teeth and so lets off the desired amount of warp to form
the loops.
To put the reed back whilst the warn is slack we pivot a lever at the top of the
loom and connect this lever at one end to the dobby and at the other end to one
end of the spring locking lever by which the reed is put back whilst the warp is
being let off for the loops.

COMPLETE SPECIFICATION.
Improvements in Looms for Weaving Terry and other Looped
Fabrics.
We, WILLIAM RICHARD GIBBS FAREY, of the firm of Samuel Farey and Son, of
Firth Shed, Skipton, in the County of York, Manufacturer, and ROBERT LANG-
HORNE, of the same address, Mill 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:-
Our Invention relates to improvements in looms for weaving terry and other

page_text: looped fabrics and the chief object of our improvements is to simplify and render
positive the motion for letting off or slackening the top warp to produce the loops.
In the accompanying two Sheets of Drawings:
Figure 1 is an end elevation and Figure 2 a back elevation of part of a loom
for weaving terry and other looped fabrics to which our improvements are applied,
Figures 3 and 4 are detail views of the mechanism which we employ for putting
the reed back whilst the warp is slack.
In these views-a designates the frame, 6 one of the ordinary top rods, c one of
the jacks or heald levers, d the connecting rod, e the treadle lever, f its fulcrum,
9 the cam for operating the treadle lever, h the tappet shaft, i the crank shaft,
the arm or lever fixed on the top rod band connected to the pawl lever k with
its spring pawl k, the shaft carried in the bracket a¹, m the ratchet wheel,
nn na n³ the train of gears for controlling the let off motion, o the top warp beam
supported in open bearings a² and driven by adjustable fluted or other suitable
friction rollers p mounted on the axle p¹ and o¹ the bottom warp beam. All the
foregoing parts have the same functions and bear the same letters of reference
as those described in the Complete Specification of our Application No. 3997 of
even date and therefore do not require any further description.
In carrying our improvements into effect we mount in suitable bearings for
example in one of the notches of the top rail stand a³ an additional top rod q on
which is fixed two arms or levers and * respectively of which
the arm is connected by a wire or the like 2 to the dobby and the other
arm is connected by a springs to a stationary bracket at and carries a spring
pawl which gears into the ratchet wheel m and is held normally in gear with it
by a spring t connected to a hooked arm 2 fixed on the lever k, consequently when
the additional rod q is moved in its bearings by the arm q¹ and connection q² from
the dobby it turns the letting off ratchet wheel m by means of the pawl r and so.
lets off the desired amount of warp from the top beam o to form the loops.
The warp for the cloth between the loops is let off at each stroke of the spring
pawl which is actuated as described in our aforesaid Specification No 3997 of
1897 but in order to prevent the ton warp from becoming too slack between the
loops we find it necessary to connect the spring pawl ¹ by a cord or the like u
passing over the pulleys u u² to the dobby so that at the required intervals that
is to say between every loop the pawl after it has moved the ratchet wheel m
far enough to let off sufficient warp to form a clear cord between the loons is
temporarily lifted out of gear for the remainder of its stroke so that no more warp
for the cloth between the loops is let off from the top beam until the pawl ¹ is
again in gear.
To put the reed in back whilst the warp is slack we pivot at as a lever at the
top of the loom and connect this lever by a wire or the like r¹ at one end to the
dobby and by a rod at the other end to one end of the usual spring-locking
levery by which when the dobby through the connections raises the locking
fevery into the position indicated by dotted lines in Fig. 4 the reed is put back
in the ordinary way whilst the top warp is being let off for the loops.
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 combination with a ratchet wheel for controlling the let off motion of
the top warp beam, of two pawls one actuated from the heald shedding motion and
regulated by a connection from the dobby to let off the top warp for the cloth
between the loops and a second nawl actuated from the dobby to let off the ton
warp for the loops substantially as herein set forth.
2. The combination with a ratchet wheel for controlling the let off motion of
the top warp beam, of two pawls one actuated from the heald shedding motion and
regulated by a connection from the dobby to let off the top warp for the cloth
between the loops and a second pawl actuated from the dobby to let off the top

page_text: warp for the loops in conjunction with a connection from the dobby to the usual
spring-locking lever to put the reed back whilst the warp is slack substantially
as herein set forth.
3. The general combination and arrangement of parts embodying our improve-
ments in looms for weaving terry and other looped fabrics substantially as herein
set forth.
