IMPROVED APPARATUS FOR CLOSING THE FEED HOLE OF OIL CANS
Year: 1885

page_text: I ISAAC WEBSTER of Kirkstall, Leeds, Yorkshire, Oil Can Manufacturer do
hereby declare the nature of my invention for "IMPROVED APPARATUS FOR CLOSING
THE FEED HOLE OF OIL CANS to be as follows:--
This invention has reference to means to be employed in closing the feed hole of
oil cans.
According to my invention I form a cavity or dish around the feed hole of the
oil can, and underneath the said feed hole I place and connect a suitably shaped
plate to a stud projecting outside the oil can, by which the said plate can be made
to Oscillate so as to cover up the hole or otherwise.
The top of the plate is provided with a projection or enlargement and leather
washer, which fits into and covers up the feed hole so that when the projection
comes opposite the said hole, it is forced therein by a spiral spring, whereby the
hole is effectually closed and escape of oil prevented.

page_text: I, ISAAC WEBSTER, of Kirkstall Leeds, Yorkshire, Oil Can Manufacturer, do
hereby declare the nature of my invention for "IMPROVED APPARATUS FOR
CLOSING THE FEED HOLE OF OIL CANS," and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention has reference to means to be employed in closing the feed hole of
oil cans.
According to my invention I form a cavity or dish around the feed hole of the
oil can, and underneath the said feed hole I place and connect a suitably shaped
plate to a stud projecting outside the oil can, by which the said plate can be made
to oscillate so as to cover up the hole or otherwise.
The top of the plate is provided with a projection, or enlargement and leather
washer which fits into and covers up the feed hole, so that when the projection
comes opposite the said hole, it is forced therein by a spiral spring, whereby the
hole is effectually closed and escape of oil prevented.
Such being the nature and object of my Invention, I will now proceed to
describe the same more fully, and for that purpose make reference to the accom-
panying sheet of drawings, wherein Fig. 1 is section of an oil can having my
improvements applied thereto. This oil can may or may not be provided with the
ordinary valve spindle a, spring b and valve c. The top of the can is made with
a feed hole or aperature d in which the oil is poured, and to close this aperture is
the object of my invention which I accomplish by means of the oscillatory plate e
attached to the top of the vertical spindle f, the foot of which works in the top of
the bridge g connected to each side of the can. Fig. 2 is a detail of those parts,
and Fig. 3 shews the aperture closed by means of the oscillatory plate e, whilst
Fig. 4 shews the aperture open.
The action of the apparatus is as follows; When it is necessary to open the
aperture the knob h on the top of the vertical spindle f is slightly pressed so as to
get the top of the enlargement i on the plate e below the thickness of metal; when
the knob h is partially turned around either to the right hand or left hand, by
which means the aperture is opened, and when it is necessary to close the aperture,
the knob is turned in the opposite direction, and as soon as the enlargement i
comes opposite to the aperture the spiral spring ; will force the enlargement into
the said aperture and close it thereby. If necessary a leather washer may be
placed under the aperture, or on the plate e so as to more effectually prevent the
escape of oil, if the can should be turned upside down. By this means an easy,
simple, and economical device is supplied for closing the feed hole of oil cans.

page_text: 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 as my invention is;
The employment of the oscillatory plate e, spindle, and spiral spring j, for
closing the feed hole of oil cans in manner substantially as described.
