MACHINES FOR PREPARING COTTON
PROVISIONAL SPECIFICATION left by the said Walter Lord at the Office of
the Commissioners of Patents on the 23rd August 1882.
WALTER LORD of Todmorden in the County of York.
MACHINES FOR PREPARING COTTON AND OTHER FIBRE
"
"IMPROVEMENTS IN
My invention relates to those machines for improvements in which Letters
Patent were granted to Water Lord and Will Lord dated September 9th 1881 (
No 3914 and also to machines known as 'Lords Exhaust Openers' the object of my
improvements being to provide a regular feed and cleaner work and an efficient
and durable porcupine' or cylinder.
In place of the two feed rollers which present the fibre to the cylinder I employ
one roller and I fit a number of levers weighted or with springs holding them to
their work on a shaft or fulcrum near the roller, these levers have ends shaped to
fit under the lower surface of the roller and the fibre from the feed apron or creeper
passes between the levers and the roller to the cylinder: by this means when a
quantity of cotton adheres together it moves only the ends of those levers over
which it passes away from the roller and the remainder of the cotton along the
roller is fed gradually to the cylinder being held by the other weighted levers
instead of passing instantly to the cylinder as is the case when a pair of rollers are
employed in the usual manner. I place one or more than one fluted or angular
roller to carry the fibre towards the feed roller and levers.
I make an improved porcupine or cylinder by fitting on a shaft a number of
discs or rings of cast iron provided with longitudinal teeth or projections with
serrated edges and I chill or harden the teeth. The cylinder thus formed is very
durable.

WALTER LORD of Todmorden in the County of York. "IMPROVEMENTS IN
MACHINES FOR PREPARING COTTON AND OTHER FIBRE
"
My invention relates to those machines for improvements in which Letters
Patent were granted to Walter Lord and Will Lord dated September 9th 1881.
N° 3914 and also to machines known as "Lords Exhaust Openers" the object of
my improvements being to provide a regular feed and cleaner work and an efficient
and durable porcupine or cylinder.
In place of the two feed rollers which present the fibre to the cylinder I employ
one roller and I fit a number of levers weighted or with springs holding them to
their work on a shaft or fulcrum near the roller, these levers have ends shaped to
fit under the lower surface of the roller and the fibre from the feed apron or creeper
passes between the levers and the roller to the cylinder: by this means when a
quantity of cotton adheres together it moves only the ends of those levers over
which it passes away from the roller and the remainder of the cotton along the
roller is fed gradually to the cylinder being held by the other weighted levers
instead of passing instantly to the cylinder as is the case when a pair of rollers are
employed in the usual manner. I place one or more than one fluted or angular
roller to carry the fibre towards the feed roller and levers.
I make an improved porcupine or cylinder by fitting on a shaft a number of
discs or rings of cast iron provided with longitudinal teeth or projections with
serrated edges and I chill or harden the teeth. The cylinder thus formed is very
durable.
And in order that my Invention may be fully understood and readily carried
into effect I will describe the accompanying sheet of drawings reference being had
to the figures and letters marked thereon.
Fig. 1 is a sectional elevation of the feed part of an exhaust opener with the
porcupine cylinder. Fig. 2 is a plan of the weighted levers or pedals. Fig. 3 is
an end view and Fig. 4 part of a side view in section of my improved porcupine
cylinder.
a is the feed roller which presents the fibre to the porcupine cylinder 6: care a
number of levers weighted or with springs to hold them to their work and mounted
on the fixed shaft or fulcrum d near the roller a: the levers chave their ends
curved or shaped to fit under the lower surface of the roller a and their other ends
are weighted as shown at c and are supported when at their lowest point by an
adjustable stationary bar e ce are fluted or angular rollers which carry the fibre
from the feed apron or creeper ftowards the feed roller a and levers c. The fibre
is fed onto the creeper and passes between the rollers e c, levers c and the roller a
to the cylinder b and when a quantity of cotton or fibre accumulates and adheres
together it depresses only the ends of those levers c by which it is held and over
which it passes under the roller a and the remainder of the cotton or fibre along
the roller a is fed gradually to the cylinder b being held by the other weighted
levers c instead of passing instantly to the cylinder as is the case when a pair of
feed rollers are employed in the usual manner. A grid is placed below the
porcupine cylinder b.
The improved porcupine cylinder bis made by fitting a number of discs or rings
of cast iron onto a shell 62: the discs are formed with chilled or hardened teeth b¹
with serrated edges: any convenient number of projecting teeth b¹ may be made
on each disc of the cylinder.

page_text: Having stated the nature of my Invention and described the manner of
performing the same
I declare that I claim.
1. The use of the levers or pedals c when applied to exhaust machines for
preparing cotton and other fibre as herein shown and described.
2. The combination of the levers c and feed roller a with an exhaust machine
for preparing cotton and other fibre as herein shown and described.
3. The combination of the levers c, feed roller a pressure rollers e e and
porcupine cylinder b with an exhaust machine for preparing cotton and other fibre
as herein shown and described.
In witness whereof I the said Walter Lord have hereunto set my hand and
seal this twenty first day of February One thousand eight hundred and
eighty three.
WALTER LORD (L.S.)
