Improvements in Oil Cans and other Closed Vessels used for
Liquids.
I, JOSEPH WOOD, of Chancery Lane, Ardwick, Manchester, in the County of
Lancaster, Tinsmith, 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 :-
It consists in certain improvements which allow of an oil can or other vessel being
readily used while held upright in the proper position, but which prevent any escape
of oil, or other liquid, in the case of accidental upset or when the can or other vessel
is not held upright.
It consists of two main parts, one of which is employed to insure that the opening
through which the can is filled is kept tightly closed when not in use, and the other
to permit air to enter the can when held in an upright position, but at no other
time.
The first part consists of a suitable lid or plug inside the feed hole or opening
through which the can or other vessel is fed, which is held firmly in position by means
of a coil or other spring and suitably made so as to insure its perfect fit and
working.
The second part consists of a metal plug containing an air hole fitted with a suitable
automatic tap or valve which I prefer to be an ordinary small tap fitted with a lever
handle weighted at the end. The weight when the can or other vessel is in an
upright position hangs directly downwards leaving the airhole open, but upon the
tilting of the can or other vessel, to any considerable extent, it swings to the lowest
side and closes the air hole, thus keeping the liquid in the vessel by atmospheric
pressure.
In order that the foregoing may be better understood I send herewith a Sheet
of Drawings in which is shown a side section of an ordinary oilcan fitted with
my apparatus. In this a indicates the feed hole, closed by lid or plug 6 held in
position by coil spring c and working by means of short tube or slide d, in slide
or tube e; the coil spring c is coiled round a central pin or tube f to insure its
perfect working; for filling the lid or plug b is pressed down into position shown by
dotted lines b².
The air is admitted through the metal plug or projection 9 by the air hole h
which is closed when the plug is out of the perpendicular by the weighted tap.
lever k swinging to the lowest side of 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 :-
:-
1st. The combined apparatus, substantially as described, and shown hereinbefore,
and in the accompanying drawings, for the purpose set-forth.
2nd. The apparatus for automatically closing the mouth of a closed vessel used for
bolding liquids, substantially as described, and shown herein before, and in the
accompanying drawings.
3rd. The apparatus for automatically cutting off the supply of air from a closed
vessel used for holding liquids, when the vessel is not in an upright position,
substantially as described and shown hereinbefore, and in the accompanying
drawing.
