COMPLETE SPECIFICATION.
An Oil Can for Lubricating Purposes, with Force-ejecting Pump.
ر
I, GEORGE CLAYDON, of Addington, near Christchurch, Canterbury, in the
Colony of New Zealand, Engineer, 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; --
The object of this invention is to provide an oil can for lubricating purposes,
having a simple and effective lift and force pump for forcibly ejecting the oil.
By means of this oil can, machinery can be easily and conveniently oiled
where an ordinary oil can could not be effectually used, and lubricators which
may be placed in unsuitable positions for filling with an ordinary oil can, may
also be readily filled.
The use of this oil can will result in saving many broken oil can spouts, and
also a saving of oil, as the oil may be forcibly ejected without requiring the can
to be tilted, the oil being forced sufficient for all ordinary purposes whilst the
can is held in a horizontal position.
My invention will be described with reference to the accompanying drawing
which represents a longitudinal section of the oil can.
Within the body of the can A a small pump barrel B is fitted; the upper
end of which is connected to and passes through the top of the oil can, and is
provided with a suitable screw cap (a); the lower end of said barrel extending
to within a short distance from the bottom of said oil can and (preferably)
beyond its centre; the said barrel being placed (preferably) at such an angle
as to allow the top to be near the handle.
A valve seat (b) is formed at bottom of the barrel and (preferably) a ball (c)
is placed therein, a guard (d) being formed above it.
A delivery pipe is connected to the barrel B and provided with a valve
seat (e) and (preferably) a ball (f) and guard (9); this delivery pipe extends
through the front of the oil can and may be continued so as to form the spout,
or it may be provided with a screw nozzle (or its equivalent) so that detachable
spouts may be connected thereto.
A plunger rod D having a suitable plunger (h) is fitted to the barrel B and
provided with a suitable spring (2).
The can having been charged with oil, it will be readily seen that upon
depressing the plunger rod D with the thumb, the valve at bottom of barrel B
is caused to close and the oil forced through the valve in delivery pipe C and
ejected from the spout; the barrel B becoming recharged with oil at each
upward stroke; the spring (i) causing the said plunger rod to recede after such
depression as soon the pressure upon it is released.
The size of the outlet in spout of course should be suited to the nature of the
oil used.
Although ball valves may be preferable for the barrel and delivery pipes, I
desire it to be understood that I do not confine myself to any particular kind of
valve, as various kinds may be used without departing from the scope of my
Price 8d3

page_text: invention; neither do I confine myself to the particular manner, as shown, of
placing the pump barrel and delivery pipe, as these may be placed in various
positions according to the construction of the oil can.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. An oil can for lubricating purposes having a force ejecting pump con-
structed, arranged, and operating substantially in the manner herein before
described and illustrated in the accompanying drawing.
2. The combination in an oil can for lubricating purposes of a pump barrel
fitted with a suitable valve at bottom and a plunger rod with plunger and retain-
ing spring at top; a delivery pipe connected to said barrel, and provided with
suitable valve substantially as and for the purposes set forth.
3. In oil cans for lubricating purposes, the application and use of a lift and
force pump for forcibly ejecting the oil, substantially as herein set forth..
Dated this 22nd day of June 1898.
GEORGE CLAYDON.
