Improvements in Automatic Lubricating Apparatus for the
Bearings of Revolving Shafts.
We, THOMAS DRAKE HOLLICK, and FREDERICK WILLIAM HOLLICK, both of 604,
Commercial Road East, in the County of Middlesex, Engineers, do hereby declare
the nature of this invention to be as follows:-
-
Our invention relates to lubricating or oiling apparatus for the bearings of
revolving shafts, in which a collar or pulley is formed or fixed upon the shaft, the
lower part of such collar or pulley running in a reservoir containing oil, so that as
the pulley revolves constantly with the shaft, it carries up with it the oil, which it
delivers to the top of the cover of the pulley by centrifugal force, this cover being
made inclined, so that the oil runs to its lower end by gravity into a gutter provided
to catch it. The oil is conducted from this gutter by pipes or passages into oilways
in the bearing and is thence returned to the reservoir.
By our invention the oil is certainly, uniformly, and effectively distributed to the
bearing, whilst the quantity so distributed can be readily adjusted and regulated,
and the apparatus cannot get out of order, as there are no working parts. It is
especially applicable to the bearings of fast-running shafts, such for instance as
those of electric motors and the like.
We attach the pulley, which takes up the oil as above described, to the shaft in a
recess in the bearing in which it revolves, so that the pulley itself takes the end
thrust of the shaft, its lower part dipping into the oil contained in a reservoir in the
lower part of the bearing. The inside of the top of the cap of the bearing above
the pulley, we make inclined so that it forms an inclined plane at the lower edge of
which a gutter is arranged which catches the oil, and pipes are attached to the ends
of this gutter which carry the oil into the bearings. Cocks or valves are fitted to
these pipes to regulate the supply.
A door is provided into the reservoir so that the latter can be filled up from time
to time as required, and so that the attendant may see that the oil is at the right
level. Cocks are also provided so that the oil may be drawn off from time to time
and replaced by a fresh supply.
At the outer ends of the bearing are formed recesses which receive the waste oil
from the bearing and from which it flows back to the reservoir below through
passages provided for the purpose.
By the device described the required quantity of the oil raised by the pulley is
directed from the gutter through the oilways, by the means of pipes, and the bearing
is kept thoroughly and constantly lubricated, whilst the shaft is revolving.
The shape of the bearing, and of the cover with inclined plane, gutter and pipes,
may be varied more or less to suit varying circumstances. Also, the one pulley,
cover, and gutter, may be used to oil two or more bearings as may be desired.

We, THOMAS DRAKE HOLLICK, and FREDERICK WILLIAM HOLLICK, both of 604,
Commercial Road East, in the County of Middlesex, Engineers, 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, and
accompanying drawing, that is to say :-
Our invention relates to lubricating or oiling apparatus for the bearings of
revolving shafts, in which a collar or pulley is formed or fixed upon the shaft, the
lower part of such collar or pulley running in a reservoir containing oil, so that as the
pulley revolves constantly with the shaft, it carries up with it the oil, which it delivers
to the top of the cover of the pulley by centrifugal force, this cover being made
inclined, so that the oil runs to its lower end by gravity into a gutter provided to
catch it. The oil is conducted from this gutter by pipes or passages into oilways in
the bearing, and is thence returned to the reservoir.
By our invention the oil is certainly, uniformly, and effectively distributed to the
bearing, whilst the quantity so distributed can be readily adjusted and regulated, and
the apparatus cannot get out of order, as there are no working parts. It is especially
applicable to the bearings of fast-running shafts, such for instance as those of electric
motors and the like.
The accompanying drawing is in illustration of our invention, Figure 1 being a
longitudinal section, and Figure 2 an end view with the cover in section, of a bearing.
Figure 3 is a view from above of the bearing, with the cover removed, and Figure 4
is a separate view of the cover from above.
We attach the pulley or disc a, which takes up the oil as above described, to the
shaft 6 in a recess, so that it revolves in the bearing in which the shaft turns, the
pulley itself taking the end thrust of the shaft, and its lower part dipping into
the oil contained in a reservoir d in the lower part of the bearing. The inside of the
top of the moveable cap e, which is fixed above the pulley by bolts at its ends at e¹,
we make inclined as shown in Figure 2, so that it forms an inclined plane at the
lower end of which a gutter f is arranged which catches the oil, and pipes or
passages are attached to the ends of this gutter at g which carry the oil into the
bearings. Cocks or adjustable screw valves (not shown in the drawing) are fitted to
these pipes at the point h to regulate the supply.
An opening provided with a door or screw is provided at i so that the reservoir can
be filled up from time to time with oil as required, and so that the attendant may
see that the oil is at the right level. A cock or cocks are also provided, so that the
oil may be drawn off from time to time and replaced by a fresh supply.
At the outer ends of the bearing are formed recesses k, k, which receive the
waste oil from the bearing, and from which it flows back to the reservoir d below,
through passages l, l, provided for the purpose.
By the device described the required quantity of the oil raised by the pulley or
disc a is directed from the gutter f through the oilways, by the means of pipes or
passages g, and the bearing is kept thoroughly and constantly lubricated whilst the
shaft is revolving.
The shape of the bearing, and of the cover with inner inclined top, gutter and pipes
or passages, may be varied more or less to suit varying circumstances. Also, the one
pulley, cover and gutter, may be used to oil two or more bearings as may be
desired.

C

page_text: invention, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The combination of the pulley or disc a upon the shaft b, dipping into oil
in a reservoir d, the cover e, having the internal gutter f inclining down to
the passages which conduct the oil to the bearing c, substantially as described
and illustrated.
2. In combination with the parts described and claimed in Claim 1, the recesses k
at the ends of the bearing c, communicating by passages with the reservoir d,
substantially as described and illustrated.
3. In combination with the parts described and claimed in Claim 1, regulating
valves for the purpose of regulating the supply of oil to the hearing, substa itially as
described.
