PROVISIONAL SPECIFIC‘ATION.
Improvements in or Appertaining to the Shedding Mechanism of
Looms.
We, THOMAS ALBERT HINCHLIFFE, of Denby Dale in the County of York, Mill
Manager, and BENJAMIN Ross, Bingley Street, Bradford in said County, Overlooker,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in or appertaining to "Knowles'" or other
similar shedding mechanism of looms in which motion is communicated from the
jack levers to the healds by means of leather straps or other flexible connections
passing over or under guide pulleys.
It is found in practice owing to the fact that there is only space for comparatively
narrow straps to be employed and that such straps are exposed to excessive wear
and tear and particularly those in "Knowles" loom used to connect the upper and
lower jack levers that said straps soon stretch and break thus being a constant source
of expense and annoyance, and the object of our improvements is to obviate this.
Our said improvements consist in employing a suitable chain in place of said
leather straps or flexible connections and particularly to those parts exposed to
excessive strain, wear and tear as the connections between the upper and lower jack
levers in "Knowles'" shedding motion.
The said chain is preferably formed with flat links adapted to pass smoothly over
the above mentioned guide pulleys.

COMPLETE SPECIFICATION.
Improvements in or Appertaining to the Shedding Mechanism of
Looms.
We, THOMAS ALBERT HINCHLIFFE, of Denby Dale in the County of York, Mill
Manager, and BENJAMIN ROSS, of Bingley Street, Bradford in said County, 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:-
This invention relates to improvements in or appertaining to "Knowles'" or other
similar shedding mechanism of looms in which motion is communicated from the
jack levers to the healds by means of leather straps or other flexible connections
passing over or under guide pulleys.
It is found in practice, owing to the fact that there is only space for comparatively
narrow straps to be employed and that such straps are exposed to excessive wear and
tear, particularly those in "Knowles'" loom used to connect the upper and lower
jack levers, that such straps soon stretch and break thus being a constant source of
expense and annoyance, and the object of our improvements is to obviate this.
Our said improvements consist in employing a suitable chain in place of said
leather straps or flexible connections and particularly to those parts exposed to
excessive strain or wear and tear, as the connections between the upper and lower
jack levers in "Knowles"" shedding motion.
The said chain is preferably formed with flat links adapted to pass smoothly over
the above mentioned guide pulleys.
The accompanying drawings illustrates the application of my improvements to the
"Knowles" shedding mechanism.

page_text: Figure 1, is an elevation of a single shaft of healds and tho jacks and pulleys used
therewith.
Figure 2, is an enlarged view of the chain showing one of the end eyes for the
attachment of the streamer wires.
The chains A, A and A2 replace the leather band frequently employed and are
connected to the streamer wires B, B' and 13 by the end eyes through which the
hooked ends of the streamer wires are passed.
It is obvious that similar chains may be used in the shedding mechanism of
Hattersley's or other looms in which flexible connections are used to transmit motion
from the jack levers to the healds and pass over pulleys like the pulleys D represented
in the drawing.
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:
The combination with a shedding motion of a loom, of a chain or chains adapted
to pass round a pulley or pulleys and transmit motion from the jack levers to the
healds, substantially as herein shown and described.
Dated this 5th day of December 1889.
