сар. This disk is provided with a central hub f which passes through
the aperture a in the cap.
gis a scutcheon resting upon the top of the cup and extending upon both sides
of the hub f, having a squared portion h engaging with the corresponding squared
portion on the hub, whereby the rotation of the hub will also carry with it the
scutcheon.
j is a nut engaging the screw threaded extension of the hub for holding the
disk and scutcheon upon the upper and lower sides of the cap. The hub is
centrally apertured and interiorly screw threaded to receive the screw threaded
stem 1, which forms an adjusting stem to limit the motion of the plunger E.
This stem is provided at its upper end with a finger piece m and the squared
portion n.
o is a collar slidingly secured upon the squared portion n of the stem, and
adapted to engage with a correspondingly squared lug p upon the hub f.
7 is a spring tending to hold the collar o in its lowest position and in engagement
with the squared lug p on the hub.
The parts being in the position shown in Fig. 2, it is evident that depending
upon the position of the lower end of the screw threaded stem l, the plunger E
will have more or less movement, and that this movement and thereby the feed may
be adjusted by turning the stem up or down. To do this it is necessary to raise
the collar o from the squared lug p when the stem may be turned within the hub.
When the adjustment is satisfactory the collar is allowed to again engage upon the
lug, being held in such position by the spring q
When the parts are in this position, the rotation of the stem will carry with it
the scutcheong and the disk d, and these parts may be turned so that the filling
and vent apertures in the disk and the cover register to fill the cup, and so that
and the scutcheon
the disk will close the apertures on the under side of the escape of the oil
will close the apertures on the top side, thereby preventing
from the inside and ingress of dust from the outside.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is:
1. In an oil cup, the combination of the casing, the reciprocating plunger
therein, a cap for the casing having a filling aperture, a valve to close said
aperture, an adjustable stem for regulating the throw of the plunger, said
stem being supported in the valve for the filling aperture, substantially. as
described.
a cap
2. In an oil cup, the combination of the casing, the reciprocating plunger therein,
for the casing, having a filling aperture, a valve to close said aperture having
a central hub passing through the cap, an adjustable stem for regulating the throw
of the valve supported in said hub, and means for connecting and disconnecting
said hub and stem, whereby the stem may be adjusted independent of the valve or
may be used to turn the valve, substantially as described.
3. In an oil cup, the combination of the cap having a filling passage therein, a
disk valve bearing against the inner face of the cap, a hub on said valve extending
through the cap, a scutcheon secured to said hub outside the cap, and means for
turning said hub, substantially as described.
4. In an oil cup, the combination of the cap, having perforations therein, a hollow
hub passing through the cap having an interior thread, an adjustable stem having
a threaded exterior passing through the hub, a disk on the lower end of the hub
within the cup, a scutcheon on the upper end of the hub outside the cap, said disk
and scutcheon controlling the upper and lower ends of the perforations in the cap,
a binding nut on the hub above the scutcheon, and a reciprocating plunger below
the stem, substantially as described.
:
5. In an oil cup, the combination with the perforated cap, of a disk for closing.
