IMPROVEMENTS APPLICABLE TO REVOLVING SPINDLES to be as follows:
Year: 1884

page_text: We GEORGE HALL Machinist and STEPHEN HULME Cotton Mill Manager both
of Chadderton near Oldham in the County of Lancaster do hereby declare the
nature of our invention for "IMPROVEMENTS APPLICABLE TO REVOLVING SPINDLES
to be as follows:-
"
This invention relates chiefly to revolving spindles used in twisting cotton and
worsted fibre but is also applicable to other kinds of revolving spindles the object
being to reduce the wear on such spindles at their bearings to a minimum.
In carrying out our invention we employ a loose bush of suitable metal or
material placed in the ordinary collar or bearing in which the spindle revolves.
The spindle is connected in any suitable manner to this loose bush so that it
revolves with it and at the same speed and thus the friction on the bearing or
collar is entirely borne by the loose bush which revolves therein.
If the spindle passes through a stationary rail this bush may be connected to the
spindle by a simple pin or screw, but if the rail is movable the spindle may be
provided with a groove or feather and the loose bush with a suitable pin or groove
respectively or the spindle and loose bush may be connected in any other suitable
manner so that they revolve together.
It will be evident that this arrangement is applicable irrespective of the position
of the spindle which may be vertical horizontal or at any angle. In some cases
especially for vertical spindles we prefer to rest this loose bush upon an inverted
cap or cup below the ordinary collar or bearing to which this inverted cap or cup
is attached by a set screw or otherwise, the spindle passing through the same.
This arrangement prevents the oil or lubricant from passing down to the bottom of
the spindle away from the bearing by confining the said oil or lubricant between
the loose bush and the collar or bearing, where the friction takes place.
It is evident that by this arrangement there will be little or no friction on the
spindle itself which will therefore last in working condition for a very long time.
Dated this 10th day of April 1884.

page_text: We GEORGE HALL Machinist and STEPHEN HULME Cotton Mill Manager both of
Chadderton near Oldham in the County of Lancaster do hereby declare the nature
of our invention for "IMPROVEMENTS APPLICABLE TO REVOLVING SPINDLES" 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 chiefly to revolving spindles used in twisting cotton and
woollen fibre, but it is also applicable to other kinds of revolving spindles the
object being to reduce the wear on such spindles at their bearings to a minimum.
Such being the nature and object of our said invention we 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
we have annexed hereunto a sheet of drawings--illustrate 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 for the sake of illustration a vertical
section of a "slubbing spindle" and its bearings constructed and arranged according
to our invention. Fig. 2. is a horizontal section of the same taken through the
line A. B. in Fig. 1.
Fig. 3, is an elevation of the same drawn partly in section.
In carrying out our invention we employ a loose bush a, a of suitable metal or
material (preferably of cast iron) placed in the ordinary collar or bearing b, b in
which the spindle c, c revolves.
The spindle c c is connected in any suitable manner to the loose bush a, a so that
it revolves with it and at the same speed and thus the friction on the bearing or
collar b, b is entirely borne by the loose bush a, a which revolves therein.
In the drawing this connection is shown as made by a key c, e fixed in the
bush a, a running in a vertical groove f, f (preferably of a saw tooth section) made
in the spindle c, c.
The bush a, a is secured by an inverted cap or cup g.g placed below the ordinary
fixed collar or bearing b, b to which latter this inverted cap or cup g, g is attached
by a set screw h (Figs 1. and 3) or otherwise so as to form an oil retainer, the
spindle passing through the same as shown.
In some cases however the spindle instead of passing through the bottom of the
cup may revolve in a footstep placed thereon. The arrangement of the cup g, g
as shown on the drawing prevents the oil or lubricant from passing down to
the bottom of the spindle c, c away from the bearing b, b by confining the said oil
or lubricant between the loose bush a, a and the fixed collar or bearing b, b where
the friction takes thereby securing a constantly lubricated spindle without danger
of the oil or lubricant returning downwards away from the bearing or working its
way up to the bobbin and thereby soiling the cotton or other fibrous material under
operation, and as there is no friction on the spindle c, c itself, the latter will last in
good working condition for a very long time.
It will be evident that this arrangement is applicable to other spindles irrespective
of the position of the same which may be vertical horizontal or inclined at any
angle

page_text: 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
The loose bush a, a revolving with the spindle c, o in combination with tho
inverted cap or cup g g forming an oil retainer substantially as herein before described
and illustrated by the drawing annexed.
