AMOS OGDEN, THOMAS MARSH, and JOHN CLAYTON, all of Ashton-under-Lyne,
in the County of Lancaster. "IMPROVEMENTS IN THE METHODS OF MOUNTING
THE BOBBINS OF SPINNING MACHINERY, AND IN ARRANGEMENTS FOR LUBRICATING
THE BEARING SURFACES."
Our Invention relates principally to the "ring and traveller "throstles employed
in spinning, but may also be applicable to other descriptions of throstles or of
spinning machinery.
In such machinery as constructed previously to our Invention the bobbin has been
mounted upon a spindle which has been fitted to revolve in bearings formed or
fixed in or upon two rails.
According to our Invention we mount the bobbin upon a tube which is fitted to
revolve upon a fixed spindle which is attached to a rail. The upper end of the said
spindle is coned or is otherwise formed to a suitable bearing surface, and a bearing
is fixed or formed in the said tube, and revolves upon the spindle end; or the
spindle end is cupped, and a centre point or the end of a screw fixed in the tube
revolves in the cup.
In one arrangement the bearing is perforated, and is screwed or otherwise fixed
within the said tube at or near the upper or outer end thereof. The bearing may
be arranged to be adjustable within the said tube.
The upper or outer end of the tube is may be closed by means of a cap; or in
case the bearing be formed out of the substance of the tube the said end may be
left solid.
We may form a slot in the upper end of the said tube, or in the said cap, and
provide the bobbin with a cross bar or wire to engage with the said slot.
The warve is fixed or formed on the lower part of the tube in cases wherein the
bobbin has to be driven.
The spindle is rendered adjustable in or upon the rail in any suitable manner.

page_text: In one arrangement a plate screws upon the end of the spindle, or upon a part
fixed thereto, and the spindle is fixed in position by means of set screws screwed
into the said plate.
In another arrangement the foot of the spindle is turned excentric, and fits in an
excentrically situated hole in a split bush, which is or may be fixed in the rail by
means of a set screw.
To lubricate the bearing surfaces we employ a cup or reservoir of a cylindrical or
other suitable form to contain the lubricant, the arrangement being such as that
the lower end of the said tube dips into the lubricant, which_rises in the space
between the tube and spindle, and effects the lubrication.
In one arrangement the said cup forms the collar upon the spindle, and is formed
with a shank for attachment to the rail..
The spindle may be fixed within the centre of the cup, or the cup may be formed
in one piece with the spindle.
We prefer that the warve shall revolve close to the mouth of the cup, so as to act
as a cover thereto, and we prefer to flanch the lip of the cup inwards, or to undercut
the cup so as to form an inwardly projecting flanch in order to check the overflow
of the lubricant.
