finally closed by a suitable spring 17, arranged
at the hinge 18.
When it is desired to supply the device with
oil, the lid 16 is raised, and the valve 13, which
5 is in the position illustrated in Fig. 2 of the
drawings, will not interfere with the intro-
d uction of the tube or spout of an oil-can into
the oil-cup 4 through one of the openings 14.
After the oil-cup is supplied with a sufficient
io quantity of oil the tube or spout of the oil-
can is withdrawn. The lubricant is forced
through the oil-passage by placing the finger
or a stick or other device on the cross-bar 12
and pressing downward on the same. This
15 will cause the valve to remain firmly closed,
and the downward movement of the plunger
will expel the oil from the oil-cup and force
the same to the exterior of the spindle. Af-
ter operating the plunger the lid is closed.
20 It will be seen that the lid is adapted to ex-
clude dust from the oil-cup and that the lat-
ter is not in the way and does not necessitate
any alteration in the construction of a ve-
hicle. It will also be apparent that the auto-
25 matically-closing valve permits the lubricant
to be supplied to the oil-cup without remov-
ing the plunger.
What I claim is-
1. In a device of the class described, the
30 combination of an axle having an oil-passage
extending to the bearing, an oil-cup arranged
at the outer end of the passage, a depressible
spring - supported plunger arranged within
the oil-cup at the top thereof and adapted to
35 he moved downward to force the oil through
the oil-passage, said plunger being provided
with an opening to permit the cup to be sup-
plied with oil and having a valve arranged to
cover the opening when the plunger is forced
40 downward, substantially as described.2. In a device of the class described, the
combination of an axle provided with an oil-
passage, an oil-cup, a spring-supported plun-
ger arranged within the oil-cup at the 'top
thereof and provided with an opening adapt- 45
ed to permit oil to be introduced into the oil-
cup, and having an automatically - closing
valve arranged to cover the opening when the
plunger is depressed, substantially as de-
scribed. 5o
3. In a device of the class described, the
combination of an axle having an oil-passage,
an oil-cup, a plunger arranged within the oil-
cup and having a cross-piece and provided at
opposite sides thereof with openings, a valve -5
arranged to close the openings when the plun-
ger is depressed, and a coiled spring arranged
beneath and supporting the plunger, sub-
stantially as described.
4. In a device of the class described, the 6o
combination of an axle having an oil-passage
and provided with a socket, an oil-cup se-
cured within the socket and provided at its
top with a stop and having a lid closing the
top of the cup and located above the stop, a 65
plunger arranged within the oil-cup and pro-
vided with a valve, and a spring supporting
the plunger in an elevated position and hold-
ing the same normally against.the said stop,
said stop limiting the upward movement of 70
the plunger and preventing the same from
raising the lid, substantially as described.
In testimony that I claim the foregoing as
my own I have hereto affixed my signature in
the presence of two witnesses.
