GEORGE BODDEN, of Oldham, in the County of Lancaster. "IMPROVEMENTS IN
THE CONSTRUCTION OF APPARATUS USED IN SPINNING AND DOUBLING COTTON
AND OTHER FIBROUS SUBSTANCES."
This Invention relates principally to "ring throstle," spinning, and doubling
frames, and especially to the arrangements for supporting and lubricating the
spindles, and to the construction of the rings of such machines; the objects of the
Invention being to simplify and facilitate the manufacture and fitting of such
parts, to ensure a perfect circulation of the oil, and to allow of the oil-cup being
replenished or cleaned out without removing it from its position.
In the first place I employ only one rail for carrying the whole apparatus. The
bolster carrier is in the form of a tube and is fixed in this rail by means of a flange
above the same and a nut beneath, the top thereof being provided with a small oil
receiver, fitting in beneath the whirl or wharve.
The bolster is also in the form of a tube, which is made with a screw thread near
its lower end on the outside, and screwed into the lower end of the bolster carrier,
the inside of which is tapped to correspond. The outside of the bolster is turned
rather smaller than the interior of the carrier (above the screwed part), so as to
leave a cylindrical chamber between the two. The main oil-cup and the "
which receives the foot-step for the spindle are cast in one piece with the bolster,
the whole being suspended by the latter being screwed into the lower end of the
bolster carrier, as before described.

"
The pap is bored out from underneath, and the footstep being fixed therein, the
hole is plugged with solder or otherwise, or instead of casting the oil-cup of one
piece with the bolster, I propose in some cases to form it from flat brass by pressure,
and to solder it on to the lower end of the bolster.
The oil cup is fitted with a lid or cover, which is capable of sliding up and down
on the cylindrical part of the lower end of the bolster carrier, so that the oil cup
can be filled or cleaned out by raising this lid or cover, without removing the cup
from its position.
The bolster is bored out rather larger than the spindle, leaving a chamber all
round, excepting at the top where the ferrule or bush is introduced so as to support
the spindle, the said ferrule being provided with a spiral or other slit at one side.

page_text: As the spindle revolves the capillary attraction causes the oil to rise up in the
inner chamber round the spindle to the top, where it passes through the spiral or
other slit in the bush, thus lubricating it, and flows over the top into the upper oil
receivers, from whence it flows down the outer chamber between the bolster and
carrier till it reaches that part where the two are screwed together, where it flows
out through holes drilled for that purpose into the lower or main oil cup, and thus
the spindle is kept well lubricated both at top and bottom.
The upper end of the bolster is fixed inside the carrier, either by means of a set
screw or by a slightly conical bush, spiral or other channels being made therein to
communicate between the upper oil receiver and the top of the outer cylindrical
chamber for the return of the oil.
For the purpose of cleaning out the oil reservoir without removing it, I sometimes
make the bottom thereof removable, and fix it by screwing into or onto the lower
end of the reservoir. In this case the footstep is cast in one piece with the bottom
of the reservoir, and is consequently removed with it, and the footstep can thus be
readily renewed when worn.
In some cases (especially when a taper foot is employed, which tends to throw the
oil upwards from the footstep), I insert in the footstep a thin metal bush, having a
spiral slot cut therein, the spiral being cut in such a direction that the revolution
of the spindle.sball.cause the oil to be forced or carried down the slot to the point
of the spindle.
In making the "rings" (whether single or double), instead of commencing, with a
ring of the thickness of the largest diameter of the flange, and then turning it
down so as to leave a thin flange projecting (as is usually done), I commence with
a thinner ring, and at the centre, or the place where the flange is required, I cut a
circumferential groove, and into this groove I spring a wire ring which acts as a
flange and supports the ring in the rail of the machine.
