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, ROBERT LANGHORNE, of
the same address, Manager, and THOMAS BAILEY, of the same address, Foreman
Overlooker, 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.
Our improvements consist chiefly in the use and application of a pattern card chain
and barrel for governing and actuating the connections which slacken the reed to
prevent it beating up the weft, and also simultaneously slacken the warp so that
when the reed next beats up a loop or any number of loops will be formed in the
fabric and either regularly or irregularly as desired.
In carrying our improvements into effect we mount a chain barrel and a pattern
card chain at the driving end of the loom and at the back end of the loom we fulcrum
two levers which carry pega arranged when lowered to come upon the pattern
chain.
These peg levers rest in a slotted plate or fork which receives a vertical reciprocating
motion from the tappet shaft or any other convenient moving part of the loom. When
the peg levers are lowered by the downward movement of the slotted plate and holes
in the pattern chain come under the pegs they drop into the holes and by suitable
connections from one of them the reed is slackened and so ceases to beat up until
the peg is again withdrawn from the hole in the pattern chain by the reverse move-
ment of the reciprocating plate or fork. In like manner the descent of the other peg
into its hole lowers a catch which grips or catches a peg wheel or other suitable
mechanism for imparting an intermittent motion and thereby actuates the vibrating
rod or slackener which governs the tension of the warp and so lets off or slackens
any required amount of yarn to forin loops in the cloth and by putting in a leese
to divide the warp we can get irregular or alternate loops from a single top warp
beam.

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, ROBERT LANGHORNE,

page_text: of the same address, Manager, and THOMAS BAILEY, of the same address, Foreman
Overlooker, 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 :-
i
Our invention relates to improvements in looms for weaving terry and other
looped fabrics.
Our improvements consist chiefly in the use and application of a pattern card
chain and barrel for governing and actuating the connections which slacken the
reed to prevent it beating up the weft, and also simultaneously slacken the warp
so that when the reed next beats up a loop, or any number of loops, will be
formed in the fabric and either regularly or irregularly as desired.
In carrying our improvements into effect we mount a chain barrel and pattern
card chain at the driving end of the loon and at the back end of the loom we
fulcrum two levers which carry pegs arranged when lowered to come upon the
pattern chain.
And in order that our Invention may be fully understood and readily carried
into effect we will describe the accompanying Sheet of Drawings in which-
Figure 1 is an end elevation and Figure 2 a part of a plan of a loom of the
type indicated, to which our improved mechanisin for letting off or slackening
the warp is applied. Figures 3, 3, 4, 5, 6 and 7 are detail views of various parts
of the mechanism.
b
On the frame 1 of the loon near the driving end we mount a chain barrel 2
and a pattern card chain 3 and at the hack end of the loom we fulcrum on a stud 4
two levers 5, 6, which carry pegs arranged when lowered to come upon the pattern
chain 3. These peg levers 5, 6, rest in a plate or fork 7 which is guided by a
bracket or brackets 8 and receives a vertical reciprocating motion from an eccentric 9
on the tappet shaft 10 or any other convenient moving part of the loom.
The lever 5 is connected by a slotted rod 11 to the usual spring locking lever 12
by which the reed 13 is put back in the ordinary way when the lever 12 is in the
position indicated by dotted lines in Fig. 1, the lever being drawn into this position
by the spring 14 connected at one end to the rod 11 and at the other end to the
loom frame. The lever 6 has a catch 15 pivoted to it and this catch grips or catches
a peg wheel 16 on the axle 17 of which is fixed a spur wheel 18 in gear with a
pinion 10 on a shaft 20 on which is mounted a cam or eccentric disc 21 connected
by a rod 22 to a levér 23 fixed on a rocking shaft 24 which carries by two arms 25
the vibrating rod or slackener 20 which governs the tension of the warp from the
top beam 27. The warp from the lower beam 28 passes over the shaft 24 and the
lever 23 fixed on the said shaft is connected by a spring 20 to the loom frame.
The chain barrel 2 is turned partly round each time the lever 5 is raised by means of
a catch 30 which is pivoted to said lever and engages a ratchet wheel 31 formed with
the chain barrel 2 and the chain barrel is temporarily held in the position intɔ which
it is turned by the spring check pieces 32 in the ordinary way well understood.
In operation when the peg levers 5 and 6 are lowered by the downward movement
of the reciprocating fork 7 and the holes in the pattern chain 3 coine under the pega
on the levers, the pegs drop into the holes and by the connections described, or by
other suitable connections, the reed 13 is slackened and so ceases to beat up until
the peg on the lever 5 is withdrawn from the hole in the pattern chain 3 by the
reverse movement of the reciprocating fork 7. In like manner, the descent of the
peg on the other lever 6 into a hole in the pattern chain 3 lowers the catch 15 into
the position shown in Fig. 3, so that the reverse movement of the reciprocating
fork 7, which lifts the lever 6, has the effect of turning the peg wheel 16 a quarter
of a revolution and thereby, through the connections described, or other suitable
connections, actuates the vibrating rod 26 against the resistance of the spring 29 and
so lets off or slackens any required amount of yarn from the top warp beam 27 to
form loops in the cloth; and by putting in a lease to divide the top warp we can get
frregular or alternate loops from a single top warp beam.
To prevent any "cracks" or spaces in the cloth, suitable provision is made for

page_text: denting whilst the loops are being formed,--for example, we fix a pin 33 on the spring
locking lever 12 and this pin, when the lever 12 is moved into the position indicated
in dotted lines, Fig. 1, raises, against the resistance of a spring 34, a lever 35 fixed
on a shaft 36 on which is also fixed a retaining catch lever 37 which controls the
ratchet wheel 38 on the shaft 39, which is connected by a train of gears, not shown,
to the taking up roller for the cloth. This ratchet wheel is driven in the ordinary
way by a pawl 40 carried by a slotted lever 41 actuated by an arm or lever 42 on one
of the slay swords. When, however, the retaining catch 37 is raised, it lifts the
pawl 40 out of gear with the ratchet wheel 38 and the lathe continues to beat up
without actuating the taking up roller until the locking lever 12 again resumes its
normal position as shown in full lines in Fig. 1. When the pawl 40 is lifted out of
gear by the catch lever 37 as described, the ratchet wheel 38 is held by a sliding
hook 43 carried on a pivoted arm 44 the sliding hook having a limited movement
sufficient to allow the weights of the bottom warp beam 28 to draw back the
ratchet 38 and the taking up roller a distance of By two teeth.
In place of the catch 16 and the peg wheel 16 we may employ any other suitable
mechanism for imparting the required intermittent motion to the vibrating rod or
Blackener 26 and in like manner we may replace any of the other parts by any known
mechanical equivalents without departing from our Invention, the essential feature
of which consists in dispensing with a dobby or other motion and substituting a
chain barrel and pattern card chain motion for putting back the reed and
simultaneously letting off or slackening the top warp.
Having now particularly described and ascertained the nature of our said Inven
tion and in what manuer the same is to be performed we declare that what we
claim is :-
1. In a loom for weaving terry and other looped fabrics, dispensing with a dobby
or equivalent motion and substituting therefor a chain barrel and pattern card
chain mechanism for putting back the reed and letting off or slackening the
warp from the top beam.
2. The arrangement use and application of the chain barrel and pattern card
chain in combination with the peg levers 5 and 6 and their respective connections to
the reed locking lever, and, vibrating rod or warp slackener in conjunction with the
reciprocating slotted plate or fork 7 all substantially as herein set forth.
3. The general combination and arrangement of parts embodying our improvements
substantially as and for the purposes herein described and as illustrated by the
accompanying Drawings.
