I, FREDERIC JAMES WARBURTON, Engineer, of 3, Grove Street, in the City
and County of Newcastle-on-Tyne, do hereby declare the nature of this invention

bearings it is necessary to provide for lateral movement to meet the effect arising
from want of balance in the rotating part.
A bearing embodying my improvements comprises a bush revolving either upon
anti-friction balls or rollers, or not, or fixed; spaces and channels or ways in
same or contiguous thereto for the entry, reception and passage of liquid and a
resilient device or devices for supporting it, all so arranged that the requisite
ability to move is obtained and controlled in a simple but efficient manner.

series of anti-friction balls maintained in position by rings or cones in turn

internal flange or collar between which and a nut the bush and cones are retained.

Improvements in Bearings for Shafts or Spindles.
I, FREDERIC JAMES WARBURTON, Engineer, formerly of 3, Grove Street, but
now of 30, Burdon Terrace, both in the City and County of Newcastle-on-Tyne,
do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:―
My invention relates to bearings for shafts or spindles revolving at high
speeds, as in, or in connection with, quick running motors or machines, in which
bearings it is necessary to provide for lateral movement to meet the effect arising
from want of balance in the rotating part.
A bearing embodying my improvements comprises a bush revolving either
upon anti-frictions balls or rollers, or not, or fixed; spaces and channels or ways
in same or contiguous thereto for the entry, reception and passage of liquid; and
a resilient device or devices for supporting it, all so arranged that the requisite
ability to move is obtained and controlled in a simple but efficient manner.
I will fully describe my invention in reference to the accompanying drawings,
which show a complete bearing constructed in accord with my improvements.
Of these drawings, Fig. 1 is a central longitudinal section, Fig. 2 is a transverse
section on the line X-Y in the preceding figure, looking to the right; and
Figs. 3 and 4 are respectively side and end elevations illustrating a modified
form of the external casing represented in Figs. 1 and 2.
According to the illustrated mode of carrying out my invention, I form the
periphery of the bush A, wherein the shaft or spindle B is keyed or otherwise
fixed to rotate therewith, to receive and revolve upon a series of anti-friction
balls C, C maintained in position by rings or cones D, D in turn encircled by an
open-ended cylinder or sleeve E provided at one extremity with an internal
flange or collar e between which and a nut F, the bush A and cones D, D are
retained. The nut F serves to effect the requisite adjustment of the cones D, D
for wear and it is locked in position by a set screw f inserted into a hole ci
indicated in Fig. 1, in the end of the cylinder E, through one of the graduated
series of holes f¹, f¹ made in the face of the nut F. However, if very fine
adjustment is required, there may be more than one hole e¹, though usually one
will be ample. The nut F is shown as almost meeting the shaft B; this is not
necessary, but only advisable for preventing the entry of dust and dirt. The
cylinder E is also furnished at each end with an external flange or collar c²
between which a ring G is located so as to abut well but easily thereagainst
and establish with same and the cylinder or sleeve E a space or annulus H con-
necting, by way of an orifice e in the cylinder E, with the bush A and, by
means of a series of small orifices e, e, also in the cylinder E, with another
space I formed in the right or outer flange 2 and closed by a ring e screwed
upon the cylinder E. Oil or other liquid supplied to this space I from a cup J
(or other source) and flows to the annulus H and the bush A by the orifices e*,
and respectively. I prefer to fix the inner flange or collar 2 of the

page_text: cylinder E by screwing, as represented in Fig. 1, for in this way the adjustment
for wear of the ring G can be conveniently effected.
The cylinder E with its ring G is inserted and retained in an appropriately
founded casing or other convenient recessed part K made of such a diameter
in regard to the cylinder and ring as to leave clearance around the former
but be in tight contact with the ring, in which condition the ring is locked
by screws g, g passed through the casing or part K, all as shown in Figs. 1 and 2.
The shape of the casing or part K is determined by the service; two forms
are exemplified in the drawings, that shown in Figs. 1 and 2 being suitable
for fixture to a bed plate or other base for which it is provided with a flange k:
whilst the design illustrated in the other figures is applicable to motors of the
enclosed type, the casing K being bolted at the end of the motor casing by means
of lugs
in
Within the casing K the cylinder E is supported by radially disposed elastic
contrivances L, L each consisting of a spring situated within a cavity
the casing K and co-acting with a plunger seated at one extremity upon the
cylinder or sleeve E and guided at the other by a gland nut 2 closing the cavity
This arrangement is clearly illustrated in Fig. 2 from which it will be seen
that the spring abuts upon the nut 2 and a collar 3 on the plunger which
rests upon the cylinder E through the bridge-piece resting upon a cut away
or flattened portion of the flanges e², e2 and in this way a good bearing is ensured.
The casing K and ring G are shown as recessed around these contrivances L, L;
this is for the purpose of permitting the reception of the bridge-piece l*.
By this construction and disposition, as the shaft or spindle B revolves, friction
is minimised by the balls C, C; longitudinal motion is avoided by the fixture
of the ring G disposed on the cylinder E; freedom to move transversely is per-
mitted by the fit of the ring G between the flanges e², e², and the resilient
devices L, L, and controlled, or the vibration damped or deadened, by the hydraulic
resistance of the liquid alternately displaced from, and returned to the spaces I
and H by the orifices et, e¹ as the cylinder or sleeve E oscillates, consequent on
the vibration of the shaft or spindle due to imperfect balance, some also passing
by the orifice e³ to the bush A for lubrication.
Thus it will be evident that by my invention I provide a very effective bearing
for the particular use specified, and though have only described and illustrated
one form of it because it is the one I find by experiment to meet my purpose
well, yet I wish it understood that I do not limit myself to the exact details,
as they are capable of various modification without departing from the principle
of the bearing. For instance, I may, without affecting the transverse move-
ment and damping action, dispense with the anti-friction balls C, C in which
event the sleeve or cylinder E may either hold the bush A, so as to be revoluble
therein, or not; or the bush A may also be dispensed with and the cylinder
or sleeve E adapted to constitute the bush for the shaft or spindle, which, in
the two latter modifications, will be arranged to revolve within the bush, now
non-revoluble. Further, for supporting the cylinder or sleeve E, I may adopt
pistons or plungers working in conjunction with liquid, elastic cushions
equivalents located within the cavities, instead of the springs 7, 1.
or
Having now particularly 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:-
1. The combination of parts constituting my improvements in bearings for
shafts or spindles, all arranged, constructed and operating, substantially as
described and shown in the accompanying drawings.
2. A bearing for shafts or spindles comprising a bush revolving either upon
anti-friction balls or rollers, or not, or fixed; spaces and channels or ways in
same or contiguous thereto for the entry, reception and passage of liquid; and

page_text: a resilient device or devices for supporting it, all arranged, constructed and
adapted to operate, substantially as hereinbefore described in reference to the
accompanying drawings.
3. In bearings for shafts or spindles, the combination of a cylinder or sleeve,
such as E, enclosing or constituting the bush and provided with flanges or collars
and rings forming spaces and with channels or ways for the entry, reception and
passage of liquid, with a resilient supporting device or devices, all arranged, con-
structed and operating, substantially as and for the purposes hereinbefore
described in reference to the accompanying drawings.
