I JOHN DODD of Oldham in the County of Lancaster Machinist do hereby
declare the nature of my invention for IMPROVEMENTS IN APPARATUS FOR SUP-
PORTING AND LUBRICATING THE SPINDLES USED IN MACHINERY FOR SPINNING AND
DOUBLING COTTON AND OTHER FIBROUS MATERIALS to be as follows:-
.
My improvements relate to what are known as Rabbeth or self contained
spindles which spindles have their footsteps and upper bearings in one tube.
My improvements consist in arrangements by which I prevent the vibration of
the above mentioned spindles by counteracting or absorbing the vibration of such
spindles when such spindles are revolving at quick speeds and facilitate the more
perfect lubrication of the spindles.
According to my improvements each spindle is mounted in a tube which contains:
the footstep and upper bearing of the spindle, the tube above mentioned con-
stituting a bolster which bolster is mounted loosely in an outer tube or bolster-
carrier containing oil-This arrangement enables the bolster by its elastic support
of the spindle to prevent the vibrations which would otherwise cause the spindle
to revolve unsteadily.
The bolster above mentioned is prevented from being turned in the bolster-
carrier by the lower end of the said bolster being shaped to fit loosely into or
against a block or stop inserted within the bolster-carrier which whilst preventing
it from turning allows the bolster to freely adjust itself to the requirements of the
spindle-The bolster is enlarged in diameter at that part which is opposite the
wharve on the sleeve of the spindle The enlarged part of the bolster fits into
the bolster-carrier so that whilst securing its concentricity with the tube of the
bolster-carrier it enables the bolster to resist the lateral pull of the band by which
motion is imparted to the spindle and at the same time allows the upper and lower
parts of the bolster to freely adjust themselves laterally-I provide the bolster
with holes or apertures to permit the oil in the bolster-carrier to pass into the
interior of the bolster to lubricate the spindle-The top of the bolster when in
position is sufficiently below the top of the tube of the bolster-carrier to allow

page_text: a ring secured upon the spindle above the top of the bolster to be below the
top of the tube of the said bolster-carrier-By these arrangements last described
any oil which may by the revolution of the spindle be caused to ascend is arrested
by the ring above mentioned and by centrifugal action is caused to be thrown off
and come against the bolster-carrier tube and be returned through grooves or
channels formed in the outside of the bolster to the oil space or chamber between
the bolster and the bolster-carrier.

Improvements in Apparatus for Supporting and Lubricating the
Spindles Used in Machinery for Spinning and Doubling
Cotton and other Fibrous Materials.
I JOHN DODD of Oldham in the County of Lancaster, Machinist do hereby
declare the nature of my invention for IMPROVEMENTS IN APPARATUS FOR SUP-
PORTING AND LUBRICATING THE SPINDLES USED IN MACHINERY FOR SPINNING AND
DOUBLING COTTON AND OTHER FIBROUS MATERIALS and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
fallowing statement :-
My improvements relate to what are known as Rabbeth or self-contained
spindles, which spindles have their footsteps and upper bearings in one tube.
My improvements consist in arrangements by which I prevent the vibration of
the above-mentioned spindles by counteracting or absorbing the vibration of such
spindles when such spindles are revolving at quick speeds and facilitate the more
perfect lubrication of the spindles.
In the accompanying drawings Fig. 1 is a side view partly in section and
Fig. 2 a plan partly in section. Figs. 3 and 4 are side views and Fig. 5 a plan of
a portion of that which is shewn in Fig. 1.
The figures above mentioned shew a method of carrying my invention into
effect. The same letters of reference are applied to corresponding parts in all the
figures above-mentioned.
In Figs. 1 and 2 above-mentioned a is the spindle mounted in a tube b which
contains the footstep c and upper bearing d of the spindle a, the tube b above
mentioned with the footstep c and the upper bearing & constituting a bolster A

page_text: which bolster is mounted loosely in the outer tube or bolster-carrier e which
contains oil. The bolster-carrier e is secured in the spindle-rail in which it is
mounted, by means of the collar or flange ƒ and a nut screwing upon the screw-
threads g in the ordinary manner.
This arrangement enables the bolster A by its elastic support of the spindle a
to prevent the vibrations which would otherwise cause the spindle a to revolve
unsteadily.
The
The bolster A above-mentioned is prevented from being turned in the bolster-
carrier e by the lower end of the bolster A being formed with a rectangular part h
which passes into a rectangular recess j formed in the bolster-carrier e.
rectangular part is shewn more clearly in Figs. 3, 4 and 5, Fig. 4 being a view
taken at right angles to Fig. 3. The recess whilst preventing the bolster A from
turning, allows the bolster A to freely adjust itself to the requirements of the
spindle a. I form the bolster A of an enlarged diameter at that part which is
opposite the warve k formed upon the sleeve of the spindle a.
The enlarged part m of the bolster A. fits into the bolster-carrier e so that whilst
securing its concentricity with the tube n of the bolster-carrier e, it enables the
bolster A to resist the lateral pull of the band by which motion is imparted to the
spindle a and at the same time allows the upper and lower parts of the bolster A
to freely adjust themselves laterally. I provide the bolster A with holes or
apertures o to permit the oil in the bolster-carrier e to pass into the interior of the
bolster A to lubricate the spindle a. The top of the bolster A when in position
in the bolster-carrier e is sufficiently below the top of the tube n of the bolster-
carrier e to allow a ring p secured upon the spindle a above the top of the bolster A
to be below the top of the tube n of the bolster-carrier e. In order to secure the
ring p upon the spindle a, I form such spindle a with a conical part a¹ upon which
the ring p is forced in any convenient manner.
When the spindle a is at work oil will pass by the holes or apertures o from
the interior of the bolster-carrier e to the spindle a and will pass from the spindle a
to the interior of the bolster-carrier e. Any oil, which by the revolution of the
spindle a is caused to ascend above the top of the bolster A is arrested by the
ring pabove-mentioned and by centrifugal action is caused to be thrown off and
come against the bolster-carrier tube n and be returned through or along grooves
or channels q formed in the outside of the bolster A to the oil space or chamber
between the bolster A and the bolster-carrier e.
In some cases instead of employing the ring p I form an enlarged part upon the
spindle a or secure a disc upon such spindle a.
The spindle a and bolster A are prevented from being drawn out of the bolster-
carrier e by means of a hook or any other similar appliance ordinarily employed
for preventing Rabbeth or self-contained spindles from being withdrawn from the
bolsters or tubes in which such spindles revolve when at work.
Figures 6, 7, 8, 9, 10 shew a method which I propose to employ in some cases to
prevent the bolster A from being turned within the bolster-carrier e. Fig. 6 is a
side view partly in section, Fig. 7 a plan partly in section. Figs. 8 and 9 are
side views and Fig. 10 a plan of a portion of that which is shown in Fig. 6. To
parts corresponding to parts shewn in Figs. 1, 2, 3, 4 and 5 I shall affix the same
letters of reference as are affixed to the corresponding parts shewn in Figs. 1, 2, 3,
4 and 5.
Through the collar or flange f of the bolster-carrier e I pass a set-screw r which
set-screw r screws into the said collar or flange f.
The end of the set-screw r passes into a hole or recess 8 formed in the
bolster A which hole or recess & is shewn more clearly in Fig. 9. The lower
extremity of the bolster A rests upon and is supported by the bottom of the
interior of the bolster-carrier e. The hole or recess 8 is made slightly larger than
the end of the set-screw r so that whilst the bolster A is prevented from turning
within the bolster-carrier e such bolster A is allowed to freely adjust itself to
the requirements of the spindle.

page_text: By the previously described arrangements I am enabled to form the sleeve / of
the spindle a of small diameter so that the bottom of a bobbin placed upon the
spindle will pass over the sleeve and into the annular recess t and be below the
top of the tube n of the bolster-carrier e.
Having thus 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 combination of parts such as are hereinbefore described, by means of which
the undue vibration of the spindles known as Rabbeth or self-contained spindles
is counteracted or absorbed and waste of the lubricating material is prevented by
means of a bolster-carrier such as e with the tube n and a bolster such as A pro-
vided with an enlarged part m and prevented from being turned round by a
suitable fixing device, the waste of lubricating matter being prevented by forming
an enlarged part or fixing a ring or disc such as p upon the spindle, the com-
bined parts being made to work substantially in the manner and for the purposes
herein-before described in reference to and as indicated by the drawings hereunto
annexed.
