23 Claims. (Cl. 308-84)
This invention relates to journal lubricators rapidly adjust itself to properly utilize journal
particularly for application to railway vehicles. end play under all conditions.
In installing journal lubricators of the type
Another object is to provide a lubricator which
utilizing lateral play of the journal or wheel hub may be easily applied to and removed from the
5 to actuate a lubricant pump, considerable dini
culty has been experienced in insuring an ade
quate supply of lubricant to the journal and brass
under unfavorable pumping conditions, such as
slow movement of the vehicle, passage of the'
10 vehicle over very smooth tracks, cold weather,
etc., while at the same time preventing undue loss
of lubricant due to excessive application thereof
to the journal under more favorable pumping
conditions, that is, when lateral play of the jour
'.15 nal in its box is relatively great, relatively fre
quent, or when the oil is warm.
Various means
have been devised for recapturing excess lubri
cant supplied to the journal which would other
Wise escape beyond the ends of the box and cellar
20 and be lost. Such means, although generally sat
isfactory, cannot always be applied to the journal
boxes due to space limitations, or for other rea
sons.
Means have also been suggested for limiting
the extent of movement of the pump piston so
as to provide substantially uniform delivery of oil
irrespective of variations in the limits and extent
of movement of the hub-face actuated plunger.
Such means have not proven entirely satisfac
30 tory, in some instances because the control mech
anism has to be especially adjusted for each in
stallation, or because the devices are too compli
cated, fragile, expensive, or diiiicult to install.
Due to the length and rigidity of locomotives,
35 the truck and driving bearings, boxes, and wheel
hub faces are subjected to substantial wear due
to lateral forces exerted, particularly in round
ing curves, and these parts must be frequently
removed and repaired or renewed. Consequently,
4 O the distances between the lubricators and hub
faces in these boxes are frequently varied, due
chiefly to variations in thickness 0f the box hub
face liners. Installation and readjustment of
45
lubricators operated by lateral play between the
boxes and wheel hub faces requires considerable
skill and laborafter each removal.
An important object of the present invention
is to provide a railway journal lubricator adapted
to deliver a controlled quantity of lubricant to the
journal irrespective of Variations in movement
of the actuator plunger as well as the dimensions
of the journal box.
Another object is to kprovide a journal lubri
55 cator which will automatically, accurately, and
boX.
5
Another object is to provide a lubricator which
is simple and economical to manufacture and
adaptable to mass production.
Another object is to provide a lubricator which
occupies a minimum of space due, in part, to r1o
the omission of the oil reservoir separate from the
box cellar.
`/Another object is to provide means in connec
tion with the lubricator for maintaining a supply
of lubricant in engagement with ñbrous lubri- v`1'5
cant distributing material engaging the journal.
Another object is the provide a lubricator which
is normally immersed in a supply of oil, thereby
facilitating construction and operation of the
pump, the pump intake being suiiiciently high â2'0
above the’floor of the reservoir to prevent water
from being drawn into the pump.
Still another object is to provide a novel wiper
device for preventing oil from escaping endwise
along the journal.
These objects and others are attained substan
_tially by the structures illustrated in the accom
panying drawings, in which

Slidable within the chamber I9 on the side of 10
the pump body casting opposite the pump cylin
der, is a control piston 39 with its stem portion
3E having its extremity 32 threaded and pro
vided with a nut 33.
Chamber I9 has a bottom
inlet 34 communicating with the supply of lubri
cant in the bottom of the cellar I. The piston 3û
is slightly smaller than the chamber I9 for a
purpose to be described hereafter.
Secured to the side of the cellar substantially
above the body 5 is the housing 36 slidably re 20
ceiving the plunger 31 which extends through an
end wall of the cellar and engages the adjacent
wheel hub face 4. On the inner end of the
plunger is a depending arm 38. Pivoted to the
body 5 by means of a pin 39 located between
the cylinders I3 and I9 is the lever 4I] which at
one end is engaged by, but not attached to, the
depending arm 33 on the Contact plunger 31, and
at the other end is engaged by the enlarged ex
tremity o1’ the pump piston stem 2I. Lever 40 30
has a horizontal slot intermediate the pin 39 and
the end thereof engaging the arm 38, which slot
loosely receives they threaded stem 32 on the con
trol piston 39 and is prevented from disassem
bly therefrom by the nut 33.
In operation, a supply of lubricant will be
maintained in the bottom of the cellar I prefer
ably to a level beneath the splash plates I1 and
I1a and the contact rod housing 36. Lateral
movement of the hub face 4 relative to the box 40
and lubricator body held securely therein will
cause the contact plunger 31 to reciprocate lon
gitudinally within its housing 36, the inward
movement of the plunger being transmitted to
the lever 40 through the arm 38. Assuming the
45
control chamber I9 to be empty when the device
starts operating, inward movement of the plung
er 31 and the adjacent end of the lever 40 will
move the control piston 39 outwardly of the con
trol cylinder, causing lubricant irom the cellar to 50
be drawn through the inlet 34. 'During each out
ward movement of the hub face, the pump piston
spring 22 will expand, causing counterclockwise
movement of the lever 40 and moving the contact
plunger 31 outwardly a short distance. Although
lubricant in the control chamber escapes slowly
past the loose piston 30, the reciprocation of the
lever 40 and the pump piston I8 will be substan
tially limited by the difference between the width
of lever 49 and the space between the nut 33 and 60
the control stem shoulder 4 I.
It is well known that the amount of relative
lateral play between the journal and wheel hub
face and the journal box varies and it may re
quire a number of reciprocations of the contact
plunger 31 to draw the control piston 30 out of the
control chamber to establish the inner limit oi’
reciprocation of the lever 49 and piston 20 as de
termined by the extreme inward movement of the
hub face and contact plunger. In case the lat
eral movement of the hub face does not again
reach its extreme inward position for a substan
tial period, lubricant will be slowly/,ejected from
the control cylinder past loose piston 30 by the
action of spring 22, resetting the Contact rod to

In practice, the piston 30 is made from fifteen to

Mounted in the hub end of the cellar is an oil
wiping device comprising a pair of wings or arms
42, one of which is shown in Figure 5a., with lugs
43 pivotally connected at the center by a pin 44.
35 On the upper surfaces of arms 42 and engaging
the journal are diagonal ribs 45. The arms 42
extend on both sides of the cellar end wall 46,
which is cut away beneath the journal to provide
therefor, and the ribs 45 wipe excess oil from the
Ak4o journal and return it through the inwardly in

may be pinned therein, as at 53. The arms 42
are free to swivel about the pin 44 and the ribs
45, preferably of relatively soft material, will wear
to conform with the contour of the journal. At
the inner end of the box, oil is wiped from the
, journal by ribs 54 on the cellar end Wall 55. If

weight of the driving wheels and axles must be
borne by the lubricators in the driving boxes, un
less the lubricato-rs are removed and replaced by
heavy blocks, which seldom is done. In order to
protect the lubricator, the vertical supports 56,
welded to the floor of the cellar, extend through
the splash plate I1 and terminate immediately
beneath enlargements 51 on the wiper arms 42.
The supporting members 56 are intended for use,
chiefly in driving boxes, as shown, to transmit the
weight of the drivers and axles to the binders, one
of which is shown in part at 58 in Figure 5, upon
which the lubricant cellars rest.

tion of the lubricator to the box. Extending
partly around the pump cylinder 68 is a collar 84
and the washer 85, yieldingly urged against the 35
wall 8| by the spring element 86 forming part of
the spring pressed plunger device, so as to seal
the aperture 83 in the wall 8|.
In Figures 8 and l9, the operative details of the
lubricator are the same as in Figures 6 and '7. 40
The reservoir 81, however, extends partially be
neath the lubricant cellar and the downward
arm 88 on the pump cylinder 89 extends through
the aperture in the portion of the cellar bottom
wall 98 which separates the cellar from the reser 45
voir. Extending around the arm 88 is the wash
er 9i which is pressed against the aperture in
the floor of the cellar by the coiled springs 92 and
93 which yieldingly support the delivery conduit
and distributor pan, so as to seal the aperture.
50
The novel lubricator is simple and economical
to'manufacture due to the inclusion of the entire
pump and control body in an integral casting,
and also due to the immersion of the entire pump
mechanism in oil so> as to avoid the necessity 55
of creating a high vacuum in the pump cylinder
and due to the location of the hub contacting
actuator plunger above the oil level so that an
oil tight housing therefore 'is not necessary. The
device may be easily applied to and removed from 60
the journal box and may be readily adapted to
various styles and sizes of journals and driving
boxes without variation of the contact plunger
or size of the pump or control cylinders. Due to
the automatic operation, a relatively large pump 65
cylinder and piston may be used and these need
not be accurately fitted, thus further decreasing
the labor and expense of manufacture and repair
and insuring the delivery of suiìîcient quantities
of oil as determined by the adjustment of the
controller piston.
There are two advantageous features inherent
in the structure described in addition to the au
tomatic regulation of the extent of movement of
the oil discharging piston when ythere is excessive 75
4
2,123,946
play between the box and the journal. When the
temperature of the oilrises and its viscosity is
reduced, it is desirable that a greater quantity of
oil be pumped to the bearing. When the journal
is operating at low speeds and, presumably, there
is relatively slow and short play between the
journal and the box, it is important that the sup
ply of oil to the journal is not interrupted for
any lengthy period.
10
When oil is thinned by the rising temperature,
it will discharge around the loose piston more
rapidly than previously and in turn the pump
plunger will operate a _greater distance. In other
words, the thinner oil does not restrict the move
5. Structure as speciñed in claim 2 in which
said inlet is provided with a check .valve and said
control chamber has an outlet substantially
smaller than said inlet whereby greater resistance
is offered to inward movement of said control
piston expelling liquid from said chamber than
to the outward movement of said piston drawing
liquid into said chamber, said loose connection
limiting the movement of said pump piston as
determined by the extremity of previous move 10
ments of said actuating means.
6. Structure as speciñed in claim 2 in which
the amount of play in said loose connection is

.'7. In combination, a journal box having a
lubricant cellar, and a journal lubricator therein
comprising a pump for delivering lubricant to
that the heavier oil does and, accordingly, the
pump plunger travels further and displaces a
greater quantity of oil.
At 20 miles per hour there may be an average
20 of ñfteen transverse movements of the journal
each minute. Higher speeds may result in sixty
ñve or seventy transverse movements per minute.
When the vehicle is traveling at low speeds, there
will be a greater length of time between the re
25 ciprocal movements of the Contact rod and,
hence, spring 22 will act on the lever dû for a
1ionger period and more oil will be forced out of
the control rod cylinder through the small open
ing. This allows the plunger to move further
30 during each stroke. In other words, the greater
the length of time between the contact strokes,
because o1" reduced locomotive speed, the less ef
fective the control feature and the greater the
travel of the pump plunger and the more oil
35 forced through the discharge conduit.
The invention is not limited to the details of
the structures described, and any type of recipro
cating lubricating device may be used with the
control mechanism illustrated. The exclusive
40 use of all such modifications coming within the
scope of the appended claims` is contemplated.
