PROVISIONAL SPECIFICATION.
An Automatic Lubricating Bearing for Axles and like Purposes.
I, ALEXIS TORDEUR-BOMMERT of 166 Rue Brogniez, Brussels in the Kingdom
of Belgium, Engineer, do hereby declare the nature of this invention to be as
follows:-
My lubricating bearing consists of an oil reservoir beneath the axle furnished
with ports and outlets, and a collar placed tightly on the axle so as to rotate
therewith.
This collar dips into the oil below and lifts by adhesion a small portion of oil at
each revolution. The oil thus lifted is directed by a cross bar on the summit into
a receptacle above the axle, whence it is distributed through sinuous channels over
the surface of the axle whence it returns to the reservoir.
A cap above the
receptacle allows the attendant to see whether the oil requires renewing. Other
covers enable the channels to be kept open. Oblique scrapers at the ends of the
bearing prevent lateral escape of oil and direct it into channels which convey it
back to the reservoir. The collar is hollowed at one part of its circumference and
cut on the opposite side so that it can be opened and sprung on to the axle.
It also contains a bolt or set screw for fastening it tightly around the axle.
Great economy of oil and very little attention are the characteristics of my
system of lubricating.

I, ALEXIS TORDEUR-BOMMERT of 166 Rue de Brogniez, Brussels, Belgium,
Engineer, 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 :-
This invention refer to bearings of machinery, shafting, and the like, and is
designed to supply a self-lubricating bearing, using very little oil, and requiring no
attention beyond the refilling from time to time of the oil container.
I will now describe the invention with reference to the accompanying drawings
in which:
Fig. 1. shows a longitudinal section of a bearing made on my system.
Fig. 2. shows a plan of the lower half of the same.
Fig. 3. shows a vertical cross-section of the same taken at the line a-b of
Fig. 1.
Fig. 4. shows a plan with the cover D and upper half U of the bearing
removed.
Fig. 5 shows a collar B capable of being fixed on an axle without having to
remove the said axle for the purpose.

page_text: Fig. 6 shows a plan of a self-aligning bearing such as "Sellers" to which my
improved system of lubrication is applied, the slots and passages before described
being cast in the bearing in the usual way; parts 2¹ of the circumference are then
turned to a spherical or convex form and these parts turn in a concave part of
an exterior casing thus permitting a good deal of side play to the bearing.
Fig. 7 shows a form of lubricator in which the oil trough is formed in the
support of the bearing and is solid therewith.
A, Fig. 1 is the axle to be lubricated.
B, is a collar surrounding same which dips in the oil below and lifts a small
portion of oil by adhesion at each revolution.
This collar may be solid with the axle or may be attached thereto in any well-
known way.
.
Q, Fig. 5 is a screw for fastening up the loose collar B, when placed on
the axle.
R, is a concavity formed in collar B to allow it to open, as shewn by the dotted
lines in Fig. 5.
Several of these cavities can be used in large collars.
C, is a cavity formed in the bearing in which B, works, which has a diameter
slightly larger than B, but is otherwise nearly of the same size.
D, is a removable cover for the cup G.
E, E, are scrapers for guiding the oil back into the trough K.
F, F, are oil channels.
G, is a reservoir in the upper part of the bearing above the collar B. This is
provided below with channels running downwards around the shaft A.
H, H', are openings in connection with the trough K.
I, I, are clearance openings at either end of the bearing preferably made larger
than the shaft A, to allow same to rotate easily.
J, J, Figs. 1 and 2 are circumferential grooves serving to collect the oil which
would otherwise escape to be gathered up by the scrapers E.
K, is the oil trough into which B dips whilst the shaft A revolves.
L, L, are sloping passages at the bottom of J, J, which conduct the oil back
into the trough K. These passages can be dispensed with if desired.
N, N, Figs. 2 and 3, are galleries to receive any oil which may escape at the
interior joints of the bearing, and conduct it back to the trough K, without allowing
it to filter through the exterior joints.
O, O, Fig. 2 are openings to receive the oil collected by the scrapers E.
01, 01, are escape ports for draining the galleries N.
S, Fig. 1 is a barrier in contact with the collar B, which is placed at the bottom
of the cup G.
T, T, are passages leading the oil down to the axle A and to the oil channels
formed in the bearing.
V Figs. 1, 3, 6 and 7 is a screw for draining the oil trough K when the oil
requires renewal, without removing the bearing. The fresh oil would be preferably
supplied from the top through the medium of reservoir G, and cover D.
When the axle revolves, the collar B, carries the oil up to the barrier S, which
stops it and causes it to accumulate in the cup G, whence it runs by the
passages T, T, into the tortuous channels below, and after lubricating the axle
returns to the trough K as shewn by dotted lines. The oil thus flows continuously
and abundantly whilst the axle revolves and the lubricant is needed.
By removing the cover D the state of the lubrication of the bearing can be
inspected.
In order to prevent the oil from spreading beyond the bearing and becoming
wasted, the scrapers E of oblique form are employed. The upper part of these
scrapers is adjusted exactly to the curve of the axle and catches the oil which
escapes from the bearing and causes it to fall into the openings O, and J and return
to the trough K.
These scrapers descend nearly as far as F the lowest level which the oil can reach

page_text: without ceasing to touch the collar B. They thus act as wipers to the shaft and
guide the waste oil down into K.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. An automatic lubricating apparatus consisting of a trough below the axle for
oil, which is lifted by the motion of the axle into a cup above the said axle, from
which it is distributed to the frictional surfaces, the oil returning at last to the
said trough. Also the ring or collar (B) fixed on and revolving with said axle
in a cavity of the bearing (C, C',) which guides it laterally. The lower part of
this collar plunges into a bath of oil and by its rotation lifts some of the oil into
the cup above (G) where it is detained by a barrier (S) in order to be dispersed
by suitable openings to the lubricating channels, whence it ultimately returns to
the trough as aforesaid, to be again brought back to the cup (G), this action con-
tinuing while the axle revolves in whatever direction or speed, as herein described
and set forth.
2. A method of retaining the oil and preventing it and the froth produced from
it from leaving the bearing. It consists of oblique scrapers (E) the upper parts
of which rub against the axle, removing the oil exuding therefrom and guiding it
back into the trough beneath by whatever direction or at whatever speed the axle
revolves, as herein described and set forth.
3. The arrangement of a collar or ring capable of being opened and then
sprung on, and screwed upon the axle, without removing the axle, and without
impairing the rotundity of said collar, by means of one or more interior recesses
or cavities (R) which impart to parts of said collar sufficient flexibility to enable
it to open and embrace the axle, without the said collar being separated into
two parts, as herein described and set forth.
