PROVISIONAL SPECIFICATION.
Improvements in Looms for Weaving Crimped or Crinkled 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
LANGHORNE, 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 fabrics having
crimped or crinkled effects produced by letting off the two warps at different
tensions so that when the taking up roller winds up the cloth the top warp is
slacker than the bottom warp and the chief object of our improvements is to let
off an even and uniform quantity of the top warp.
In carrying our improvements into effect we fix a lever on the ordinary top rod
which raises and lowers the heald shafts and receives an oscillating or rocking
motion in its bearings by means of a connecting rod from the tappet shaft. This
lever carries a spring pawl to drive a ratchet wheel which controls the letting off
motion for the top warp beam. The ratchet wheel has a pinion secured to it which
is geared by change wheels with a spur wheel on the axle of a pair of adjustable
fluted corrugated or other friction rollers by which the top warp beam is supported
and by which it is driven. The axle of the top warp beam is supported in open
or slotted bearings and is weighted by levers and weights or otherwise suitably
weighted.
When the spring pawl drives the ratchet wheel motion is communicated through
the gearing to the friction rollers and so to the top warp beam whereby a certain
amount of warp is let off and delivered and by changing the toothed wheels the
amount of warp thus delivered can be varied as required.

page_text: In carrying our improvements into effect we fix a lever on the ordinary top rod
which raises and lowers the heald shafts and receives an oscillating or rocking
motion in its bearings by means of a connecting rod from the tappet shaft. This
lever carries a spring pawl to drive a ratchet wheel which controls the letting off
motion for the ton warp beam. The ratchet wheel has a pinion secured to it which
is geared by change wheels with a spur wheel on the axle of a pair of adjustable
fluted corrugated or other friction rollers by which the top warp beam is supported
and by which it is driven.
In the accompanying Sheet of Drawings―
Figure 1 is an end elevation and Figure 2 a back elevaton of part of a loom for
weaving crimped or crinkled fabrics to which our improvements are applied.
In these views, a designates the frame of the loom, one of the ordinary top
rods, c one of the jacks or levers fixed on the rod and by which the heald shafts
are raised and lowered, d the connecting rod by which the top rod receives its
oscillating movement from the treadle lever e which is fulcrumed at f and is
actuated by a treading cam g on the tappet shaft h, the latter being driven as usual
from the crank shaft i. On the top rod b we fix an arm or lever j which is con-
nected to a lever k fulcrumed on a short shaft I supported in bearings in a
bracket al. On the shaft are secured a ratchet wheel m and a pinion n and the
lever k carries a spring pawl to drive the ratchet wheel m which controls the
letting off motion of the top warp beam o. The ratchet wheel m is geared by
means of the pinion n, spur wheel n¹ and pinion n² to the toothed wheel ³ fixed on
the axle of a pair of adjustable fluted corrugated or other friction rollers p by
which the top warp beam o is supported and by which it is driven. The axle of
the top warp beam is supported in open or slotted bearings a³ and is
weighted in the usual way by levers and weights, not shown, or is otherwise suit-
ably weighted. The bottom warp is drawn directly off the lower warp beam o¹ in
the usual way. When the lever moving with its top rod 6 depresses that end of the
lever k to which it is connected the spring pawl drives the ratchet wheel m and
this motion is communicated through the pinion n and gears n² to the axle p¹
and friction rollers and so to the top warp beam o whereby a certain amount of
warp is let off and delivered and by changing the pinion n and adjusting the
position of the carrier wheels ¹ m² the amount of warp thus delivered from the
top warp beam can be varied as required. The ratchet wheel m is prevented from
turning back by means of a pivoted retaining catch m¹.

Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is: :-
1. The combination with a ratchet wheel the axle of which is geared by change
wheels with the axle of adjustable fixing rollers on which the top warp beam is
supported and by which it is driven, of a spring pawl engaging said ratchet wlieel
and actuated by levers or other suitable connections from one of the ordinary top
reds which receives an oscillating motion by connections from the tappet shaft all
substantially as and for the purposes herein set forth.
2. The general combination of parts embodying our improvements in looms
for weaving fabrics having crimped or crinkled effects produced by letting off the
two warps at different tensions, an even and uniform quantity of the top warp
being let off positively so as to render it slacker than the bottom warp substantially
as herein set forth.
