1, FERDINAND NAPS of Bielitz, Austria, Manufacturer do hereby declare the nature
of this invention to be as follows :-
The object of the present invention is to provide an oil-can or oiler so constructed
that, on each pressing down of the thumb piece, only a determinate quantity of oil is
allowed to flow out of the nozzle of the oiler, and when the thumb piece is not pressed
down the orifice remains closed and no oil can flow out.
To accomplish this I construct the improved oiler as follows, that is to say: In the
case of a smail oiler, such as employed with small machinery, in which the discharge
tube is in the central axis of the oil vessel or bulb, I arrange the thumb piece at the
bottom of the bulb, this thumb piece being attached to a rod carrying at its other end
a small piston working in a cylinder at the lower end of the discharge tube. The
thumb rod is extended beyond the piston and carries on its outer end a valve body.
having its seat arranged in the discharge tube. On the thumb rod, a short distance
above the cylinder in which the piston on the thumb rod works, a spiral spring is pro-
vided which tends to draw the piston home thereby pressing the valve down on its seat.
In this position the oiler is hermetically closed. Upon inclining the oiler some oil
flows through suitable channels in the body of the oiler from the bulb into the part of
the discharging tube situated between the piston and the valve, and when the thumb
piece is forced inward against the pressure of the spring the valve is opened, the
piston advances, and in so doing presses a determined quantity of oil out through the
discharge tube while it closes tightly the oil channels, thereby preventing the flow of
oil directly out from the bulb through the discharge tube.
It is obvious that the pressure on the thumb piece though continued cannot cause a
larger quantity of oil to flow out from the oiler than that contained between the piston
and the valve; if therefore it is desired to discharge a larger quantity of oil, the
thumb piece must be relieved from the pressure when it will be drawn back by the
spring, the oil channels leading from the bulb to the space above the piston are thus
opened, and this space again fills with oil, so that on again applying pressure to the
thumb piece another quantity of oil is discharged.

page_text: In larger oilers having a horizontal discharge tube or nozzle the arrangement of
piston, valve, thumb rod, spring and oil channels is substantially the same; only the
arrangement for actuating the thumb rod is somewhat different. In such oilers the
thumb piece has, for convenience of manipulation to be arranged in proximity to
the handle, preferably above the same and opposite to the discharge tube. I therefore,
in oilers of this class connect the thumb piece with the thumb rod by the medium of a
double cam so shaped that, when the thumb piece is pressed down, the thumb rod is
projected forward, whereby the oil is driven out through the discharge tube. Instead
of the double cam I may employ a cam and pinion, the cam being connected with the
thumb rod and the pinion gearing with a rack attached to the thumb piece; or I may
employ a pinion only for coupling the thumb piece and the thumb rod, each of these
being provided with a rack gearing with the said pinion.
The operation of such large oilers is substantially the same as that previously
described with reference to the upright oilers.

page_text: 1, FERDINAND NAPS of Bielitz, in the Empire of Austria, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :—
My invention relates to oil cans or oilers, and has for its object to provide the same
with a closing device of such construction, that when the thumb piece of the said
closing device is depressed only a determined quantity of oil will flow out of the
spout or nozzle of the oil can, while when the said thumb piece is not depressed the
will remain closed, so that no oil can flow out.
In the accompanying drawing,
Figure 1 shows in vertical section the improved closing device applied to an oil can,
or oiler, having an upright outlet pipe.
Figure 2 is a sectional view, showing the device applied to an oil can having a
substantially horizontal spout.
Figure 3 is a plan of the closing device detached.
Figures 4 and 5 are similar views to Figures 2 and 3, respectively, illustrating a
modification of the said invention, and
Figure 6 is a sectional view illustrating another modification.
9:
The improved closing device comprises a cylinder a, which is provided with the
valve the inlet opening d, and the air pipe e.
e,
A socket having an air vent is
also provided to permit the outflow of the oil from the nozzle.
Into the cylinder a is fitted the piston b, which is secured upon a rod æ, which
carries the valve e and a spring h.
By pressing the rod a forward the valve c is opened, and the piston is moved
simultaneously forward thereby discharging the oil contained in the cylinder a.
As shown in Figure 1 a tube surrounds the rod and the spring, and the device
is operated to allow the flow of oil by pressing directly upon the rod æ, through the
medium of the thumb piece a'.
When the discharge pipe or nozzle is horizontal the motion of the rod is caused
by the segments in combination with the pressing pin 7, as shown in Figures 2
and 3, or by the single segment which is provided with a toothed wheel, and a
pressing pin having a rack, as shown in Figures 4 and 5; or by the toothed wheel
4, with which engages the pressing pin / provided with a rack, a rack also being
arranged upon the rod as shown in Figure 6.
As shown in Figures 2 and 3 a guide 7 is arranged at the rear end of the rod a and
receives the segment which is of larger radius than the segment. These two
segments are connected by the disc ³, and thus constitute a double cam which moves
upon a pin in the lugs mm². The segment engages with a socket attached to
the end of the push rod working in a guide p.
The motion of the rode is caused by depressing the pin through the medium of
the thumb piece a', thus moving the segment & downward and the other segment k¹
forward.

page_text: In lieu of this arrangement I sometimes employ as hereinbefore stated a single
segment attached to or formed integral with a toothed wheel which turns upon a
pin in the lugs m. The wheel, and consequently also the segment, are moved by
means of the pressing pin which slides in a socket p¹ and between the two lugs m
and has, instead of the excentric guide a rack n
By pressing upon the pressing pin through the medium of the thumb piece a the
wheel is caused to turn upon its axis, the segmental cam is therefore pushed
forward, causing a forward motion of the rod, and consequently also of the piston b
the valve c opening simultaneously.
2,
Instead of the constructions herein before described, the pressing pin and the rod
can both be provided with racks which engage with the foothed wheel as shown in
Figure 6 whereby the employment of cams is rendered superfluous.
When the piston during its forward motion closes the inlet opening d, the afflux
of oil from the can is not possible until the pressure upon the pressing pin ceases.
The spring then exerts its reactive power, draws back the piston b, and at the same
time closes the valve c, whereupon the inlet aperture d is again opened. When the can
is placed in an inclined position the cylinder is again filled with oil, which can only be
discharged when pressure is again exerted upon the thumb piece. Accordingly, every
time the pin (or in vertical oil cans the rod e) is depressed a certain quantity of oil
can be discharged, and should the pressure be continued for a long time no more oil
can flow out, until the inlet aperture d is again opened and pressure re-exerted. Thus
with oil cans or oilers provided with the improved device a considerable saving of oil
is effected.
The air pipe e permits the rapid flow of oil into the cylinder a when the valve e is
closed and the inlet aperture d is opened.
The air hole (or air pipe y Figure 1) in the socket fenables the rapid outflow of
the oil from the nozzle or spout.
Having now particularly described and ascertained the nature my the said invention
and in what manner the same is to be performed I declare that what I claim is :-
:-
First In an oil can, or oiler, the arrangement of a valve e in connection with a
piston b, and a rod supporting the same, in such a manner that on the said rod being
depressed the oil discharge aperture is opened, and the inlet apereture d closed, so
that only the small quantity of oil between the said piston and valve is discharged,
substantially as described, with reference to Figure 1 of the drawing.
Second In an oil can, or oiler, the discharge pipe or nozzle of which is in a
substantially horizontal position, the combination of the parts characterized by the
preceding claiming clause with actuating mechanism comprising either a double
cam k, (Figures 2 and 3) or a single cam k, a toothed wheel, a pin or rod
and a rack n (Figures 4 and 5); or a toothed wheel & engaging with a rack on the
pressing pin and another rack on the rod a (Figure 6) all substantially as described.
