Improvements in Oil Cans.
I, CHARLES LUCIUS BELLAMY, of Arlington, in the County of Hudson, and State
of New Jersey, one of the United States of America, Manufacturer, do hereby declare
the nature of my 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 especially to the construction and arrangement of oil cans
employed for filling lamps, &c., and has for its object the provision of means and
mechanism whereby the user of the can will be notified when the receptacle being
filled has received the requisite quantity of oil, and at the same time the flow of oil
will be automatically stopped.
To attain the desired end, my invention consists essentially in an automatic over-
flow check-nozzle provided with a visual indicator, and in certain novel and useful
combinations and arrangements of parts, and peculiarities of construction and opera-
tion, all of which will he hereinafter first fully explained, and then pointed out in the
claims.
In the drawing,
Fig. 1 is a sectional view of a can to which my device is applied, showing the con-
struction, arrangement, and method of operation of the parts.
Fig. 2 is a side view of a portion of the can, showing the visual indicator.
Like letters of reference, wherever they occur, indicate corresponding parts in both
the figures.
A is the body of the can, B is the bail or handle, C the finger piece, and D the
filler. E is the oil spout, provided with a division, F, so arranged as to throw the
body of the escaping oil towards the upper side of the spout, a small passage or
drip G, being left below the inner end of said division. H is a glass box, or chamber
secured upon spout E, and I is a wheel, the wings whereof project up into chamber H,
and down into the spout E.
L is an air tube extending from within the can, near the top thereof, to the outer
extremity of the oil spout.
When constructed and arranged in accordance with the foregoing description, the
operation of my device is as follows:
When it is desired to supply oil, as to a filler, R, of an oil pot or fount, the flowing
oil will cause the wheel I, to rotate, its movement being plainly seen by the operator;
air passes to the interior of the can through the tube, L. When the oil in the
receptacle has reached the level of the outlet from the oil spout, and the inlet for air,
the flow of air into the can will be at once cut off, thus stopping the flow of oil, and
consequently the rotation of the wheel, I, notifying the user that the lamp, or other
oil receptacle, is full.
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 As a new article of manufacture, an oil can provided with an automatic over-
flow check-nozzle, and indicator, in which is comprised a liquid discharge tube, a
separate air admitting tube, and a movable, mechanical, visual indicator, substantially
as shewn and described.
2: The combination with an oil can, of an overflow check-nozzle, provided with a
movable, mechanical, visual indicator, substantially as shewn and described.
3: The combination with an oil can, of an automatic overflow check-nozzle and

page_text: indicator, in which is comprised an inlet for air, an outlet for oil, a transparent
chamber mounted upon the outlet spout, a division located in the oil passage, as set
forth, and a movable, mechanical indicator within said chamber, substantially as shewn
and described.
Dated this 24th day of September 1890.
