AN IMPROVED CAN FOR FILLING OIL OR OTHER LIQUID INTO LAMPS OR OTHER VESSELS
Year: 1884

page_text: I JOAQUIM ANTONIO DE MACEDO of Scarcroft Lodge in the Parish of Thorner
in the County of York Gentleman do hereby declare the nature of my invention
for AN IMPROVED CAN FOR FILLING OIL OR OTHER LIQUID INTO LAMPS OR
OTHER VESSELS to be as follows:-
I make an oil-can in the shape of a watering-can, but with a small spout of a
convenient length for filling lamps-Inside the spout is a small metal tube and
through this metal tube I place a glass tube, connected at one end with the top
interior of the can and extending at the other end, to within a quarter of an inch
of the end of the spout. On the top of the can is a funnel with a conical neck
which can be stopped by a cork and at the top of the funnel is a lip to prevent
dripping.
Now if the oil-can be filled with oil and the neck of the funnel be stopped with
a cork, on inserting the spout in the lamp the oil will cease running as soon as the
level of the liquid in the lamp rises high enough to touch the end of the glass tube
within the spout for then no further air can be admitted into the can by the said
glass tube and that this has taken place is made known by seeing the oil rise in
that part of the said glass tube which is not enclosed within the spout.
By this arrangement there is no danger of filling a lamp so that it will overflow
thereby saving waste and saving the extra time and care required in filling opaque
lamps where it is difficult to see the height of the liquid inside the font.

page_text: I JOAQUIM ANTONIO DE MACEDO of Scarcroft Lodge in the parish of Thorner
in the county of York gentleman do hereby declare the nature of my invention
for AN IMPROVED CAN FOR FILLING OIL OR OTHER LIQUID INTO LAMPS OR
OTHER VESSELS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
I make an oil-can say in the shape of a watering-can but with a small spout of
.convenient size for filling lamps Inside the spout, S (see the annexed drawing
which represents a vertical section of the oil-can) is a small metal tube T extending
at one end to within a quarter of an inch of the end of the spout and the opposite
end protruding through the back of the spout. Through this metal tube TI place
a glass tube G connected at one end by means of an elbow E and a perforated
cork CC with the top interior of the can, and extending at the other end to within
a quarter of an inch of the end of the spout so that any liquid issuing from it while
'the can is resting on a level surface will run down the spout into the can-On the
top of the can is a funnel F with a brass neck stopped by a brass plug P which can
easily be removed and replaced and which is attached to the can by a chain-At
the front edge of the funnel is a lip L which prevents any oil which may have
adhered to the inside of the funnel during the act of filling, from dripping on the
lamp or table when the can is being used.
c
Now if the oil-can constructed as as above be filled wholly or partially with oil
and the neck of the funnel stopped by the plug, on inserting the spout into a lamp
that it is desired to fill, and elevating the handle the oil will commence running
and will continue to run until the level of the liquid in the lamp rises to the end
of the glass tube when it will prevent any further ingress of air up the glass tube
and thus cause the oil to cease running into the lamp.
In using this oil can there is no danger of overfilling the lamp so as to overflow,
which often happens in filling lamps made of an opaque substance in which case it
is very difficult and often impossible to see the level of the oil within the font.
This invention therefore prevents any waste of oil, waste of time, disagreeable
smell and other annoyances resulting from overfilling lamps.
•
I do not limit myself to making cans only in the shape shewn in the drawing but
make the body of any convenient shape or size according to the purpose for which
it is intended and I make the spout either bent or straight, longer or shorter
according to circumstances.
In the foregoing decription, when I say "oil" I mean any liquid, and when I say
"lamp" I mean to include any vessel which it is desired to fill with any liquid to
a given height or to any indefinite height short of overflowing.

page_text: Having now particularly decribed and ascertained the nature of my invention
and in what manner the same is to be performed I declare that what I claim is
The general arrangement and combination of parts forming an oil-can or oil-
feeder as above decribed.
