(01, 1s4_3)
The present invention relates to improvements
in lubricating devices for railways, and more par
ticularly refers to a device for lubricating the rail
the rails with the improved pump device shown
applied thereto‘ partly in section.

which a lubricant chamber within the applicator
body is in alinement with the elongated narrow
slot from which the ribbon or sheet of lubricant
15 and i6 represent the rails of a railroad over
'20 emerges upon the side of the rail head.
A further object of the invention is to provide
an improved reservoir for the supply of the lubri
cant which will retain the body of lubricant under
Figure 2, the wheels having the internal ?anges
constant pressure and which will enable the resto
25 ration of the parts to the initial position ready for
re?lling with ease and e?iciency.
A still further object of the invention is to pro
vide an improved form of pumping and lubricant
controlling device whereby quantities of the lubri
30 cant will be supplied to the applicator in propor
tion to the amount of tra?ic traveling over the
road.

of the outer rail of the curve that requires lubri
cation.
In Figures 1 and 2, the improved applicator is

In the drawings, wherein like symbols refer to
like or corresponding parts throughout the several

views,
The improved applicator is illustrated more
particularly in Figures 3 to 7 inclusive. In these
?gures a body or casting 2| is shown having a
lubricant chamber 22 therein.
The casting is
formed of metal or other suitable material and
the chamber may be cored out or otherwise pro

from the casting along one side wall of the cham
ber 22 and extends alongside of the rail head It.
A removable cover plate or strip 25 is disposed
opposite the lip wall 23 and spaced slightly there
from to produce an elongated continuous channel
or mouth open at its upper and adjacent the side
of the rail head and communicating below di
rectly with the chamber 22. The mouth 24 is

preferably vertically above the chamber.
The
cover plate 25 is carried by, or has formed there
on, a bead or ?ange strip 26 seated in a cavity 26'
of the casting 2|. The upper surface of the bead
26. is preferably ?ush with the shelf 21 of the
casting, this shelf being cut down from the lip 23
to accommodate the ?anges of the car wheels. 55

The cover plate 25 or outer wall of the lubricant
slot 261 is preferably of hardened steel so that it
will normally maintain its proper position and
alinement against collapse inwardly toward the
lip wall 23, but which at the same time will with
stand any strain or stress of the car wheel ?ange
when passing thereover. The mouth or slot 24
will deliver the lubricant in a thin flat sheet or
ribbon against the upper portion of the side of
10 the rail head it, whereby such lubricant is picked
up by the flanges 29 of the wheels l8 and carried
about onto the curve for the purpose of lubricat
ing the ?anges and the rail head.
The body of the applicator is provided with
bosses 28 and 29 for ?tting up against the web 30
of the rail.
Centrally of the device is an elbow 3i or other
inlet connection for the lubricant, which connec
tion is coupled to the supply pipe or tube 2|’
20 shown in Figures 1 and 2.
The body or casting 2! of the applicator is se
cured to the web of the rail by means of exten
sions Zia at each end of the applicator; such ex
tension being provided with an elongated hole 22a
" to permit of vertical adjustment and through
which the bolts 22b pass. Lugs 31' are parts of
the extensions 2 la and are located at each end of
the applicator body or casting 2|. The guard
plates are provided with elongated holes 34*‘ in
registry with the holes 22a of the extensions.
Such guard plates are fastened on the extensions
by means of screws, bolts or other fastening de
vices 35. The lugs 31 are threaded to receive
screws 38, the head or other ends of which are
' adapted to engage against the ?ange 39 of the
rail for the purpose of adjusting the vertical
height of the device including lip 23 with refer
ence to the tread of the rail and with respect to
the ?anges 20 of the wheels 58.
Grease is supplied to the applicator through
the pipe 2E’ which pipe connects with a pump
device carried near the companion rail l5, as
shown in Figures 1 and 2. This pump device is
shown in Figures 8, 9 and 10 and comprises gen
45 erally a body iii] of cast metal or other suitable
All)
construction having a lower chamber ill with a
port 42 for the discharge of the lubricant into the
tube or pipe 2i’. A second threaded opening in
the lower wall of the device is closed by a threaded
plug 43.
This plug 43 is in alinement with a valve assem
bly and by removing the plug 43 the valve stem
64 and the valve 135 may be pushed up into the
place occupied by these parts, as shown in Figure
l i 8.
The valve i5 is normally urged'upwardly by a
coil spring 113 into a closed position against the
valve seat Ill surrounding a port 48, which port is
made in the diaphragm or septum 48 extending
horizontally across the body or casing 138. Above
60 this septum is a chamber supplied with lubricant
by a tube or pipe 56 entering a port 5| of the
casing lid. The valve stem 44 is carried by a
plunger 52 which plunger reciprocates in a cylin
der 53 formed in the upper portion of the casing
Kill above the port 48. The coil spring 1&5 takes
against the valve ‘l5 at its upper end and at its
lower end engages the plug 43. The plunger 52
carries a hollow threaded stem 5d supporting a
threaded button 56.
By rotating the button 56
its threaded shank 56a will traverse the threads
in the socket of the hollow stem 54, thus adjust
ing the button 55 as to its height with respect to
the car wheel ll. The height of the plunger will
control the throw or extent of the vertical motion
' of the plunger 52 and of the valve 45 and the
amount the port 48 is opened. A key or set screw
51a may be used to secure the button 56 against
rotation after adjustment. The casing 46 is car
ried by a plate 59 secured by bolts or other fasten
ing means E0 to the web of the rail Hi.
This pump device receives its supply of lubri
cant through the pipe 59 from a reservoir shown
more particularly in Figures 11, 12 and 13. The
reservoir includes a container 6| open at its bot
tom to slide down over a ?xed plunger 62 having 10
a packing cup 6-3 secured thereto and extending
along the wall of the container 6|.
At its upper end the container is closed by a
removable cover 64 to admit of the introduction
of the lubricant into the container body.
The plunger 82 is stationary, being carried by
a support 65 upstanding from a base or pedestal
66. The plunger is preferably concave to an
opening 67 to which is connected the pipe or con
20
duit 50.
Projecting from the sides of the movable con
tainer 6| are the ledges 68 on which move the
rollers 69 carried by the arms 10. The arms 10
have bearings ll a?lxed to a shaft ‘i2 journaled
in the bearings 73, which latter bearings are sup
ported from the pedestal 66. One of the arms
'10 is provided with a socket T4 for a rod or handle
‘l5’. This handle gives leverage for raising the
arms 1i] and the container 6!. One of the arms
'56 is formed with a segment 15 against which the 30
beveled nose '55 on the cross bar ll of a latch
device is adapted to engage. The cross bar 11 is
carried upon arms 18 which straddle the rear
lower end portion of the segment when the latter
is in the rear position shown in Figure 13. The
arms 78 form a bell-crank with the treadle or
foot piece 79. The bell-crank is pivoted or ful
crumed on the pedestal as indicated at 8?).
A modification of this latch device is illustrated
in Figure 14 where the segment l5a is shown as 40
carrying a trailing latch or dog 8i pivoted at 82
on the segment and having its beveled or rounded
nose 83 wiping along the upper surface of the
pedestal 66a which is provided with one or more
locking projections 89 having abrupt shoulders 45
and rounded backs.
The reservoir or tank 6| will tend to descend
by gravity of its own weight but preferably one
or more weighted rings 85 are placed over the
tank, resting on lugs 86. In the use of the device,
the reservoir, when elevated to substantially the
position shown in Figure 13, is ?lled with lubri
cant or grease and the cover ?ll restored. The
weights 85 will tend to bear the tank 6! down
wards, thus forcing out the grease through the
pipe 50 to the pump device. Thus the grease or
lubricant in the reservoir 8| is maintained under
a constant pressure which is tending to force the
grease out of the reservoir and into the pumping
60
device.
When the reservoir BI is exhausted, that is
when it has reached the lower limit of its down
ward movement, as illustrated in dotted lines in
Figure 13, then the cover 64 is removed to break
any possible vacuum that might form in the
reservoir as the container
6|
was
elevated.
Thereupon a rod 15’ is introduced into the socket
l4 and with the leverage thus gained, the arms
10 are swung up about the shaft 72 thus causing
the rollers 69 to lift the container 6|. In exe 70
outing this movement the locking device or latchv
shown in Figure 13 will by reason of its weight
follow the rear edge of the segment ‘I5 until,
when the container is fully elevated, the arms 18
of the latch will lie substantially horizontally on
3
2,077,077
the pedestal and the nose 16 will engage against
the rear edge of such segment. Thus the tank 6|
will be held elevated without the use of the oper
ator’s hands which may be left free to re?ll the
5 reservoir. By use of the foot-piece 19 the latch
may be lifted after the reservoir is ?lled and the
cover 64 restored.
In accordance with Figure 14, the latch 8| will
be trailed along as the segment is rotated until it
10 arrives at substantially thedotted line position
when the tank 6| is fully elevated. The latch
may be kicked out Whenever the operation of the
device is to be resumed.
The pressure of the lubricant entering the
15 pumping device will raise the plunger 52 and close
the valve 45. In this action it will be aided by the
coil spring 46.
When a wheel I‘! of a car passes
over the rail l5, the tread of the wheel, which is
wide enough to extend upon the outside of the
20 rail head, will encounter the button 56, depressing
the same to the position shown in Figure 9, it
being understood that ordinarily the grease pres
sure and the spring 46, or either of them, will
maintain the button 56 in the position shown in
25 Figure 8 where the same is raised above the plane
of the rail tread.
As'the wheel passes over the rail and over the
button 56 it causes the button 56 and the plunger
52 to be depressed, thus ejecting a charge of
30 grease through the port 48 and valve 45 which
has been opened by this action. The grease there
upon flows out of the lower chamber 4|, through
the pipe connection 2|’ and to the applicator.
When the wheel has passed over the button 56
the spring 46 and the lubricant pressure will tend
to restore the parts upwardly and close the valve
45. This valve 45 keeps the reservoir pressure
from constantly forcing the lubricant out through
the slot in the applicator.
40 The lubricant, from the pipe 2|’ enters the body
chamber 22, which chamber may be molded with
in the body 2| or otherwiseproduced therein.
The grease has. open and immediate access from
the chamber 22 to the slot 24. By adjusting the
4.5 screws 38 this grease may be applied to any ele
vation upon the rail head.
The device produces a continuous sheet or rib
bon of grease applicable to all parts of a desig
nated lineal section of rail and to continuous and
50 uninterrupted portions of the wheel ?ange pass
ing along such rail head, the application of the
lubricant being thus surer and the e?lciency of
the device accordingly increased.
As shown in Figures 5 and 6, the lip, composed
55 of the inner and outer walls 23 and 25 may be
adjusted vertically so that the open upper delivery
mouth thereof is disposed at a height slightly
above the lowermost point of the wheel ?ange 20.
The lip may also be adjusted to be even with or
lower than the lowermost point of the wheel
flange 20.
.
It is obvious that various changes and modi?
cations may be made in the details of construc
tion and design of the above speci?cally described
embodiment of this invention without departing
from the spirit thereof, such changes and modi
?cations being restricted only by the scope of
the following claims.
