IMPROVEMENTS IN THE CONSTRUCTION OF MACHINERY OR APPARATUS EMPLOYED FOR PREPARING AND SPINNING COTTON AND OTHER FIBROUS MATERIALS
Year: 1881

page_text: LETTERS PATENT to John Walker, of Hyde, in the County of Chester, for an
Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF MACHINERY OR
APPARATUS EMPLOYED FOR PREPARING AND SPINNING COTTON AND OTHER
FIBROUS MATERIALS."
PROVISIONAL SPECIFICATION left by the said John Walker at the Office
of the Commissioners of Patents on the 24th December 1881.
JOHN WALKER of Hyde in the County of Chester. "IMPROVEMENTS IN THE
CONSTRUCTION OF MACHINERY OR APPARATUS EMPLOYED FOR PREPARING AND
SPINNING COTTON AND OTHER FIBROUS MATERIALS."
My Invention relates to such machinery or apparatus employed in preparing
and spinning cotton and other fibrous materials as is provided with drawing rollers
for drawing out the fibre and more particularly to that class wherein the drawing
rollers are not mounted in a level position, but are tilted or fixed on an incline
from back to front.
The object of the Invention is to support the top clearing rollers so as to prevent
them from rolling off the front rollers and to keep them always in equal contact
with both rollers.
The Invention consists in an inclined bearer or bearers (slotted or otherwise) on
or against which the pivots projecting from the centre of the clearers rest. The
said bearers are either fixed to, or form part of, any hook, strap, cap bar, or cap
neb, used for weighting the rollers; or any other fixing or part of the frame, and
so fixed that they form inclined planes, up which the clearers slide as they
increase in diameter; the face of the said bearer being so inclined that the clearer
will always touch the two front rollers whether the latter are clean and free from
waste or increased in diameter by waste lapping on them.
That is to say, the incline of the bearer must be at right angles to a lino
forming a tangent to the upper circumference of the two front rollers:

JOHN WALKER of Hyde in the County of Chester. "IMPROVEMENTS IN THE
CONSTRUCTION OF MACHINERY OR APPARATUS EMPLOYED FOR PREPARING AND
SPINNING COTTON AND OTHER FIBROUS MATERIALS."
My Invention relates to such machinery or apparatus employed in preparing
and spinning cotton and other fibrous materials as is provided with drawing rollers
for drawing out the fibre and more particularly to that class wherein the drawing
rollers are not mounted in a level position, but are tilted or fixed on an incline
from back to front.
The object of the Invention is to support the top clearing rollers so as to prevent
them from rolling off the front rollers and to keep them always in equal contact
with both rollers.
The Invention consists principally in an inclined bearer or bearers (slotted or
otherwise) on or against which the pivots projecting from the centre of the
clearers rest.
Such being the nature and object of my said Invention I will now proceed to
describe in detail the manner in which the same is to be or may be performed
or carried into practical effect and in order that the same may be clearly-understood
I have annexed hereunto a Sheet of Drawings illustrative thereof and have marked
the same with Figures and letters of reference corresponding with those in the
following explanation thereof.
Fig. 1 in the annexed Drawing represents a side elevation of an inclined
drawing-roller stand with my Invention shown as applied thereto, a, a being the
stand, b, b the top drawing rollers, c, c the bottom drawing rollers d, d the cap bar,
e, e the cap neb and f, f the strap.
g, g is the top clearing roller and h, h is the inclined bearer or support, on or
against which the pivots projecting from the ends of the clearers rest as above
described. In Fig. 1 this inclined bearer is shown as fixed to the saddle k, k. In
Fig. 2 it is shown as fixed to the cap neb e, e, in Fig. 2x it is shown as applied to
the cap bar d, d; and in Fig. 3 it is shown as forming part of the strap fif which
supports the weighted lever.
The said bearers may either be fixed to any hook, strap, saddle, cap bar or cap
neb used for weighting or holding the rollers, or they may form part of the said
strap or they may be attached to any other fixing or part of the frame in which
case they form adjustablo inclined planes, up which the clearers g, g slide as they
increase in diameter, the face of the said bearer h, h being so inclined that the
clearer g, g will always touch the two top front rollers b, b whether the latter are
clean and free from waste, or increased in diameter by waste lapping on them;
that is to say, the incline of the bearer h, h must be at or about right angles
to a line forming a tangent to the upper circumference of the two top front
rollers b, b.
Having now described the nature and object of my said Invention together with
the manner in which the same is to be or may be perform-d or carried into
practical effect I wish it to be understood that I claim as my Invention the con-
struction and application to the class of preparing and spinning machinery above

page_text: referred to, of an inclined bearer or bearers, to support the top clearing rollers
substantially in the manner and for the purposes herein before more particularly
set forth and described.
In witness whereof I the said John Walker have hereunto set my hand and
seal this Twentieth day of June in the year of our Lord One thousand
eight hundred and eighty two.
JOHN WALKER.
