This invention relates to means for recover
ing excess lubricant supplied to journals, and
particularly railway locomotive driving journals,
much of which lubricant Would otherwise escape
endwise of the journal and be centrifugally
thrown off outside the journal box and lost.
In order to insure satisfactory lubrication of

These objects and others are attained substan

leading through the crown bearing or from a res
ervoir carried in the lower part of the journal box
15 by means of a suitable pumping device such as
that illustrated in co-pending application Serial
No. 558,719, ?led April 22, 1931 in the name of
the present inventor.
Where the lubricant is pumped from a reser
20 voir within the box itself, the pump may be ad
justed to constantly maintain a pool of oil at
the surface of the journal providing so-called
bath lubrication.
However, much of the oil supplied to‘the jour
25 nal in such quantities is squeezed endwise beyond
the bearing brass and, in the absence of suitable
recapturing means, is thrownoff and lost. The
oil recapturing devices heretofore in use gener
ally have not been ef?cient enough to prevent ex
30 cessive oil losses where lubricant is constantly
supplied to the journal by gravity or where bath
lubrication is provided and, accordingly, such
lubrication, though desirable from a mechanical
standpoint, has not been considered practical.
It therefore becomes necessary to provide bet
ter means for recapturing lubricant than have
heretofore been devised in order to permit the
furnishing of relatively large quantities of oil
to railway journals without substantial waste.
40 Moreover, with the use of e?icient oil recapturing
means a relatively simple inexpensive pump may
be provided, or oil may be supplied conveniently
and simply to the bearing by gravity from an
overhead reservoir.
The main object of the present invention is to
provide e?icient means for recapturing oil escap
ing beyond the ends of the bearings‘ of railway
vehicle lubricated journals.
A more detailed object is to provide novel
50 means for recovering oil thrown off from the
journal outside the journal box cellar and re
turning the same to‘ a cellar within. the box.
Another object is to provide an oil wiper for
vehicle journals which may readily adjust itself
to the position and contour of the journal and

In Figures 1 and 2 of the drawings, the inven
tion is shown applied to a locomotive driving box
having the usual heavy side walls i for engage "25
ment with'the underfran'le pedestal (not shown)
and receiving the crown bearing brass 2, the ends
of which are undercut as at 3.
Located in the
‘lower portion of the driving box is a lubricant
cellar 4 which is downwardly enlarged in its inner $30
portion to form a lubricant reservoir‘ 5. VWithin
this reservoir is the body portion 6 of a lubricant
pump which is actuated by the contact rod 1
extending through a tubular housing 8 within
the cellar and engaging, the hub 9 of the adja—*135
cent driver. It will be understood that lateral
play of the driver and journal relative to the
driving box will cause lubricant in reservoir 5 to
be pumped through the screen l0, body‘ 6, tubular
housing 8,;transverse passage i I, and upright de 40
liveryrmember I 2 to the cup l3 where, during
operation of the pump, a pool of oil is maintained
in contact with or adjacent to the surface of the
journal. Ball checks I4 and i5 are provided to145
trap the lubricant in cup l3.
V - Maintained adjacent the journal by means of
a spring 16 is a lubricant distributing device
shown in'the present instance ‘as formed of a
series of strips ll of suitable absorbent'material .»5_0
such as felt or celotex and intervening spacer
vstrips I8 which may be of wood. At the. ends .
of the lubricant cellar are ba?le plates 19 and
29 for preventing the splashing out of lubricant
overv the top edges of the cellar end walls_;2ll and 255
22 which are slightly spaced from the journal as
shown at 23 in Figure 2.
The details of the driving box, pump, and oil
distributor shown do not in themselves con
stitute the present invention. The pump is more
clearly described in the above-mentioned co
pending application Serial No. 558,719.
In order to prevent lubricant from escaping
over the side walls 24 of the cellar, these walls
10 extend into grooves 25 formed in the side por
tions I of the driving box immediately beneath
the side edges of the bearingbrass 2. This
feature is covered in co-pending application
Serial No. 728,894 ?led June 4, 1934 by the pres
15 ent inventor. At the inner end of the box is
provided a closure member 26 surrounding the
journal and including a portion 28 forming a
cover for the reservoir 5. Closure member 26
includes a felt strip 21 with its inner edge bent
20 over as at 29 and snugly engaging the journal to
prevent the loss of lubricant through this por
tion of the box.
It has been observed that lubricant squeezed
out from under the bearing tends to form in a
25 ring adjacent the end thereof and is centrifugally
thrown oil from the journal in the form of drops.
In order to bring this oil ring within the end
wall 22 of the cellar, the brass is undercut as at
3. However, due to the lateral play of the jour
nal, some of the accumulated drops will be
thrown outside the cellar wall. In order to re
cover the oil thrown off the journal outside the
cellar and which would be otherwise lost, a series
of cooperating wiping and collecting devices A, B
and C are provided for wiping the journal, and
particularly the portion thereof outside the cellar
outer wall 22, and'returning the recovered lu
bricant to the cellar; '
The wiper A, Figures 3 and 4, comprises an
elongated box-shaped housing 30, which extends
through and is rigidly secured to ‘the end wall
22 of the lubricant cellar. The top wall of the
housing is longitudinally slotted to receive the
journal wiping rib 3|. The rib 3| is enlarged
45 in its lower portion’to form shoulders 32 for
seating against the slotted top wall of the hous
each side. At the inner end of the body por
tion is a curved arm 44 arranged to seat against
and extending partially around the surface of'
the journal. This arm serves as a stabilizer for
the wiper.
Seated in a hemispherical bearing 45 in the
undersurface of the wiper body is a pin 46 (Fig
ure 2) extending through aperforation in the
splash plate 20 and urged upwardly by a coiled 10
spring 4'! seated against a washer 48 held against
movement along the pin by means of a cotter key
49. A spacer bushing 50 surrounds the pin 46
and has slots 5| for accommodating the cotter 49.
The wiper body is thus yieldingly and adjustably 15
maintained in contact with the journal.
At the sides of the wiper B are upright bolts .
52 seated on the bottom of the cellar and ex
tending through the splash plate 20 and ter
minating in close proximity to the journal. 20
These bolts serve to relieve the wiper mechanism
of excessive vertical loads in case the driving
box is jacked up as for renewing the bearing
The wipers A are located closer to- the side 25
edges of the bearing than the wiper B and, ac
cordingly, these need not extend quite as far
beyond the end wall of the cellar as the latter
in order to recover oil moved away from the end
of the hearing by longitudinal play of the jour 30
nal. However, it is desirable that all of the wipers
extend beyond the end of the endof the bearing.
There will be a tendency of lubricant to travel
longitudinally within the grooves 25 in the sides ,
of the driving box and in order to recover lu 35
bricant in these grooves which may travel beyond
the end wall of the cellar, the angle-shaped cups
C are provided which extend to the ends of the
grooves. Each of these cups is formed of a metal
strip bent in the formof an angle and its side v49
"edges buttwelded to the end wall of the cellar
and underlying the end of the depending lip of
the box groove 25. Collected lubricant is drained
through the hole 53 in the cellar wall. The col
lecting devices C are illustrated and claimed in 45

journal by means of a bent flat spring 39 nor

surface of the wiper.
In this as well as the pre
,vious formthe wiping rib is yieldingly and ad
justably maintained in contact with the, journal.
The wiping device B,.detailed inFigures 6, '7
and 8,. comprises a body portion’ including ribs

inwardly and downwardly. Lubricant recovered

covered, only just enough being allowed to es

hub liner. Each of the wipers is yieldingly
mounted on the end of the cellar and arranged
to collect lubricant on the journal and return
the same into the cellar by gravity. With the
use of these recovery devices bath lubrication of r
the journal is made practical and also it is pos
sible to supply oil to the journal by means of a 460
simple inexpensive gravity feed without the dan
ger of excessive losses.
