IMPROVEMENTS. IN MACHINERY OR APPARATUS FOR PREPARING AND SPINNING COTTON WOOL AND OTHER FIBROUS MATERIALS
Year: 1884

page_text: I, JOHN DODD of Oldham in the County of Lancaster Machinist, do hereby
declare the nature of my invention for IMPROVEMENTS. IN MACHINERY OR
APPARATUS FOR PREPARING AND SPINNING COTTON WOOL AND OTHER FIBROUS
MATERIALS to be as follows:-
My invention relates to what are commonly called "clearers" used in machinery
for preparing and spinning cotton wool and other fibrous materials and consists in
arrangements by which. I retard the motion of such "clearers "-For this purpose
I employ a brake such brake consisting in a rod bar or plate hinged or jointed at
one end to any convenient part of the machine and resting upon the "clearer" the
motion of which is to be retarded and thereby retarding the revolution of the
"clearer" aforesaid.
"
The aforesaid retardation of the motion of the "clearer" enables such "clearer
to keep the rollers upon which the said clearer' acts clean and also enables the
fibres removed from the aforesaid rollers to become coiled or wound upon the said
"clearer
in an uniform and regular manner thus preventing the formation of
what are known as "curls" or "thin rolls."

OR
I JOHN DODD of Oldham in the County of Lancaster Machinist do hereby
declare the nature of my invention for IMPROVEMENTS IN MACHINERY
-APPARATUS FOR PREPARING AND SPINNING COTTON WOOL AND OTHER FIBROUS
MATERIALS-and-in-what..manner the same is to be performed,-to-be-particularly_
described and ascertained in and by the following statement :=
My invention relates to what are commonly called "clearers" used in machinery
for preparing and spinning cotton wool and other fibrous materials and my
Finvention consists-in-arrangements by which I retard the notion of such clearers.
In order that my invention may be thoroughly understood-I-will-now-proceed
to describo the same with reference to the drawings hereunto annexed-In the
accompanying drawings Fig 1 is a side elevation partly in section and Fig:-2 a
plan of so much of a machine for preparing-or-spinning cotton wool or other fibrous
material as is requisite to illustrate my invention. a b c are the bottom-drawing-
rollers above which and supported thereby are the top-drawing-rollers d e f g is
the "cap bar" which retains the top-drawing-rollers def in their respectivo
positions above the bottom-drawing-rollers a b c-Resting upon and rotated by
the top-drawing-rollers de is the "clearer" h the circumference of which clearer h
may be covered with flannel cloth or other material in the usual manner-A
bracket jis secured to the cap bar g by means of the set screw k. The bracket j
instead of being formed separate from and secured to the cap bar g. as shown may
be formed as a part of the said cap bar g. To the bracket jis jointed by means of
a pin l. a rod bar or plate m. which rod bar or plate m extends across and rests
upon the clearer h. The top-drawing-rollers d. e. revolve in the directions indicated
by the arrows A. B respectively and tend to rotate the clearer h in the direction
indicated by the arrow C. The rotation of the clearer h in the direction indicated
by the arrow C is retarded by the rod bar or plate m which rod bar or plate m
resting upon the clearer h acts as a brake to retard the rotation of such clearer h.
The retardation of the rotation of the clearer h enables such clearer h to keep the
rollers de upon which the clearer h acts clean and also enables the fibres removed
from the top-drawing-rollers d. c. by the clearer h to become wound upon such
clearer h in an uniform and regular inanner thus preventing the formation of what
are known as "Curls" or "thin rolls" When it is desired to remove the clearer h
from the machine for examination cleaning or other purpose the rod bar or plate m
is turned upward upon the pin and after such rod- bar or plate m is turned
upward upon the pin the clearer h may be removed for examination cleaning or
other purpose.
Figs 3 and 4 show another method in which my invention may be carried into
effect Fig 3 being a side elevation partly in section and Fig 4 a plan of so much
of a machine for preparing or spinning cotton wool or other fibrous material as is
requisite to illustrate this modification of my invention-As some of the parts
shown in Figs 3 and 4 are similar to some of the parts herein before referred to in
i

page_text: reference to Figs 1 and 2 I shall affix to such parts the letters of reference affixed
to such parts in Figs 1 and 2-h is the clearer resting upon and supported by
which clearer h is a curved plato p the lower curved surface of which curved plate p
corresponds or nearly corresponds in shape to the circumference of the clearer -
Secured to and projecting from the curved plate p is a pin q which pin q passes
into a hole formed through the rod bar or plate m which rod bar or plate m is
hinged so as to be capable of being turned upon the pin -The weight of the rod
bar or plate m and the weight of the curved plate p press the curved plate p upon
the circuinference of the clearer h so as to cause such curved plate p. to act as a
brake to rotard the rotation of the clearer h the curved plate p being retained in
position upon the clearer h by the pin q.
I apply one or more of either of the above described arrangements of brake to
cach clearer as may be desired or required for retarding the rotation of the clearer.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
The application of a brake or brakes to each of the clearers used in machinery
for preparing and spinning cotton wool and other fibrous materials such brake or
brakes being constructed arranged and operating substantially in the manner and
for the purposes hereinbefore described and shown in reference to and in and by
Figs 1. 2. 3 and 4 of the accompanying drawings.
