PROVISIONAL SPECIFICATION.
An Improved Oiling Can.
I, BERNARD HIPPOLYTE CHAMEROY, Engineer of Vesinet (Seine and Oise)
France do hereby declare the nature of this invention to be as follows :-
This invention relates to a construction of oiling can such that it can be readily
applied to lubricate, by delivery of more or less oil, in any direction, and that its
contents cannot be spilled even if it is inverted. The lower part of the can is
separated by a partition from the upper part, a lower compartment being thus
formed into which oil can pass slowly through a small orifice in the partition. To
another orifice of the partition is attached the lower end of a pump, the barrel of
which extends obliquely upwards through the upper end of the can, and is covered
by a cap through which passes the piston rod terminating in a knob or button to
receive the pressure of the finger. Under the piston, within the barrel, is a helical
spring which urges the piston upwards as far as permitted by an adjustable nut on
the piston rod butting against the cap of the pump. At the bottom of the pump
is a conical suction valve kept seated by a light spring, this valve having a guide
stem which passes up into a central bore of the piston and its rod. The discharge
valve is a cylindrical piece of leather, or such like material, which is held in an
inner mouth of the can and which has in its lower part a round hole fitting on the
discharge pipe of the pump. In its upper part, communicating with this hole, is a
slit of the leather which opens a little to allow passage of oil outwards when it is
forced by the pushing down of the piston, but which closes against air entering
when the piston is urged up by the spring. This valve is enclosed within an outer
neck which terminates in a taper outlet tube, preferably somewhat bent so that the
issuing oil can be directed into parts which a straight tube might not easily reach.
The can has an orifice with a screw plug for filling it, and has an air inlet tube
extending down into it.

An Improved Oiling Can.
I, BERNARD HIPPOLYTE CHAMEROY, Engineer, of Vesinet, (Seine and Oise,)
France, 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 :-
This invention relates to an improved construction of piston oiling can which
delivers the oil in all positions and which, as may be required, supplies a jet of
oil sufficiently strong to be projected several yards, or a weak jet, or a delivery
in drops. The can is so arranged that the oil cannot escape therefrom, even when
it is inverted, unless the piston is acted upon.
The lower part of the can is separated by a partition from the upper part, thus
forming a lower compartment into which the oil penetrates through an opening
formed in the partition; this opening is so arranged that when the can is turned
upside down the oil will only escape slowly from the lower compartiment.

page_text: To another opening of the partition is attached the lower end of a pump barrel
which extends obliquely upwards, passes through the side of the can, and is closed
at its upper end by a cap through which passes the piston rod; this rod has a
button at its upper end which is pressed upon by the finger or thumb when it is
required to work the pump. Below the piston within the barrel is a helical
spring which presses the piston upward as far as a stop on the piston rod will
permit, in coming in contact with the cap of the pump cylinder.
At the lower end of the pump cylinder is a suction valve which is kept down
on its seat by a slight spring. As the suction of the pump takes place in the
bottom compartment, it follows that the pump will act for supplying oil even
when the can is turned upside down, inasmuch as there will always be oil in this
compartment, as it can only escape slowly therefrom as above stated.
To the lower part of the side of the pump barrel is connected a delivery tube
extending up to a delivery valve at the base of the discharge spout or nozzle ;
this valve is so arranged that it will not allow the oil to escape into the nozzle
unless the pump is actuated, even if the can be inverted, and also, so that it will
open to a greater or less degree, according as the pump is actuated suddenly or
slowly, whereby the oil may be made to issue either in a jet or drop by drop.
Figure 1 of the accompanying drawings sbews a vertical section of an oil can
constructed according to my invention;
Figure 2 shews in plan the details of the suction and delivery valves which !
employ with this arrangement.
Figure 3 shews a vertical section of a modified construction of the can.
Figure 4 shews a top view of the discharge valve employed in this construction.
Figure 5 shews bow with an oiling can constructed according to my invention,
parts of machinery can be lubricated that are situated very high up, or that can
only be lubricated from below, the oiling can being in this case retained in the
upright position, when discharging oil.
A is the reservoir of the can, which may be of any suitable form. B is the
lower compartment, which communicates on the one hand with the reservoir A by
an opening 6 of such a form or size as only to allow the oil to flow slowly out of the
compartment B when the can is inverted; on the other hand the compartment
communicates with the pump C by the opening b¹.
The pump may be of any desired form; Figure 1 shews the arrangement which
I prefer to employ.
In this construction the pump barrel C is formed of a cylinder arranged obliquely
within the interior of the reservoir A, the lower end being fixed in the partition B'
enclosing the compartment B, and at its upper end it is made to project through
the can and has its outer end provided with a screw thread on which is screwed
the cap C. The latter has a hole of a sufficiently large diameter to allow of the
free passage of the piston rod D.
This rod has a button D' at its upper end, and at a certain distance from this it
is made of enlarged diameter so as to form a shoulder which, in butting against the
inner face of the cap C', limits the upstroke of the piston. A spring D° which
bears with its lower end on the lower end of the pump barrel and with its upper
end against the piston, tends to keep the latter at the upper end of its stroke.
The suction valve is formed of a leather disc e Fig. 2 covered by a thin copper
disc e. In these discs are cut annular slots e, e, which form, in the central part
of the disc, circular tongues ee connected at one point to the outer part of
the disc.
The tongue e of the leather disc constitutes a valve the edges of which rest on
the annular seat C³ formed by the lower end of the pump barrel. The tongue
of the copper disc always bears upon the tongue e and acts as a spring for bringing
it back on its seat after it has been raised by the suction stroke of the pump.
From the lower part of the pump barrel projects a discharge pipe F which fits
into the neck piece of the can A.
The upper face of this neck piece serves as the seat of the discharge valve g

page_text: which is identical in construction with the suction valve e. The neck piece has an
external screw thread on which is screwed the internally threaded base H' of the
discharge nozzle H.
An internal shoulder of this base is made to bear upon the edge of the copper
disc g' and thus holds the discharge valve in place.
The oiling can at Fig. 3 only differs in details from the above described
construction. In this case the stop on the piston rod for limiting the stroke of the
pump is formed by a screw nut D' screwed on the threaded upper part of the
piston rod D, so that it can be adjusted in position. The piston is formed of an
enlargement D' of the rod D having a threaded recess for receiving the plug D'
which serves for securing the cupped leather D³.
The suction valve is formed by a conical plug E which is pressed on its seat by
a slight belical spring El bearing with its upper end on the piston. The valve E
is provided with a guide stem E' which slides in a tubular recess D' in the piston
aud stem.
The discharge valve is formed by a small solid cylindrical piece of leather G
having a longitudinal slit G₁ formed through its centre as shewn at Figs. 3 and 4.
The discharge pipe F extends to the opening of the oil can A into which the
leather G is fitted, so that when the latter is fitted on to the end of the pipe F, it
closes the opening of the can as a stopper. When fitting G on F care must be
taken to leave a sufficient length of the former projecting beyond F so that the
sides of the slit of that part, in closing together, will effectually prevent the
leakage of oil out of the can. But if the oil is forced through the tube F by
means of the pump, the pressure of the liquid will force open the slit so as to allow
any desired quantity thereof to be discharged.
The can must of course be provided with a small pipe for the inlet of air
arranged in any convenient manner, for example as shewn at I on the drawings,
J is a stoppered opening for filling the can.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In an oiling can, the combination with a main oil chamber of a lower oil
chamber communicating with the former by a small opening, a pump barrel
communicating with the lower chamber and having a piston actuated in the one
direction by a spring and in the other by the hand, a suction valve arranged at the
lower part of the pump barrel, a discharge pipe extending from the lower part
of the pump barrel to the discharge nozzle of the can, and a discharge valve closing
the lower part of the discharge nozzle and so arranged as to be always closed when
the pump is not actuated, and to open to a greater or less extent according as
greater or less force is exerted on the pump piston, substantially as described.
2. Oiling cans constructed substantially as described with reference to the
drawings.
