other Fibre.
We WALTER LORD and WILL LORD, both of Canal Street Works, Todmorden, in
the County of York, machine makers do hereby declare the nature of said Invention
for IMPROVEMENTS IN MACHINES FOR PREPARING COTTON AND OTHER FIBRE to be
as follows:-
Our Invention relates particularly to the Invention for which Letters Patent
No 3914 were granted to us on the 9th day of September 1881, and the chief
object of our Invention is by an improved arrangement of fans to draw the cotton
or other fibre more effectually through the beater cylinder or cylinders and to
distribute the same more evenly on the dust cages.
In applying our Invention to a Crighton opener or other similar opener fitted
with (or without) a porcupine and other arrangements according to our said Patent,
we propose to place between the cylinder and the wire cage, one or more exhaust
fans, preferably two, mounted adjustably on a shaft, placed across the path of the
fibre: these fans are provided with a damper (or dampers) to regulate the draught
and assist in laying the fibre evenly on the wire cage, the fans and the damper
being all and severally effectual in evenly distributing the fibre on the cages.
The usual dust fan (or fans) is employed to remove the dust from the cages and
take the air from the exhaust fans.
Our improvements may also be applied to Crighton or other similar openers of
the ordinary construction.

We WALTER LORD and WILL LORD both of Canal Street Works Todmorden in
the County of York Machine Makers, do hereby declare the nature of our invention
for IMPROVEMENTS IN THE MACHINES FOR PREPARING COTTON AND OTHER FIBRE
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 particularly to the Invention for which Letters Patent
No 3914 were granted to us on the 9th day of September 1881, and the chief
object of our invention is by an improved arrangement of fans to draw the cotton
or other fibre more effectually through the beater cylinder or cylinders and to
distribute the same more evenly on the dust cages.
In applying our invention to a Crighton opener or other similar opener fitted
with (or without) a porcupine and other arrangements according to our said Patent,
we propose to place between the cylinder and the wire cage one or more exhaust
fans preferably two mounted adjustably on a shaft placed across the path of the
fibre: these fans are provided with a damper (or dampers) to regulate the draught
and assist in laying the fibre evenly on the wire cage, the fans and the damper
being all and severally effectual in evenly distributing the fibre on the cages.
The usual dust fan (or fans) is employed to remove the dust from the cages and
take the air from the exhaust fans.
Our improvements may also be applied to Crighton or other similar openers of
the ordinary construction.
And in order that our Invention may be fully understood and readily carried
into effect we will describe the accompanying two sheets of drawings reference
being had to the figures and letters marked thereon.
Fig. 1 is a side elevation-Fig. 2 a transverse vertical section and Fig. 3 a plan
of part of a Crighton or other similar vertical opener to which our improvements
-have been applied,-a designates the vertical opening cylinder and 6 the passage
from the same to the exhaust fans c. c which are mounted adjustably on the
shaft d which is driven by means of the pulley e.
We prefer to employ two exhaust fans as shown and to place them across the
path of the cotton or other fibre as it issues from the cylinder a and passage b and
passes along the passage 61 over the grids f to the dust cages not shown in the
drawings; but we might if more convenient place a fan or fans in the feed in
front of or at the side of the cylinder a, instead of placing them on the delivery
side of the cylinder as herein shewn and described.
We fit a damper in the passage b which may be used in either of the positions g
or g¹ to regulate the draught and to assist the fans in distributing the fibre evenly
as it passes through them to the dust cages.
A dust fan or fans not shown is employed as usual; but the chief function of
this fan which formerly had to draw the fibre unassisted, and did not spread it

page_text: evenly, is to remove the dust from the cages and to draw the air from the exhaust
fans c. o' while the latter draw the fibre forward and assisted by the dampers
distribute it evenly on the cages.
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 use and application in a Crighton or other similar opener of one or more
exhaust fans and a damper or dampers placed on either the feed or delivery side of
the cylinder but preferably between the cylinder and cages substantially as herein
set forth, for the purpose specified.
2. In a Crighton or other similar opener the combination with the usual dust
fan or fans, of one or more exhaust fans provided with a suitable damper or
dampers and placed across the path of the fibre substantially in the manner and
for the purposes herein described and as illustrated by the Drawings annexed.
