Improvements in Cans for Oil and other Liquids.
I, FREDERICK LIED, of Columbus, County of Franklin, State of Ohio, United
States of America, Commercial Traveller, do hereby declare the nature of this
invention to be as follows:-
--
The lower end of the delivery-spout of the can is provided with a flap-valve,
pivotally secured thereto by means of a wire loop. The face of this valve is
provided with a cork or other clastic packing, by means of which a perfectly-tight
joint is formed between said valve and the lower end of the spout when said
valve is closed. The rear of said valve is provided with an angular arm, having
an aperture, the latter adapted to receive the reduced end of an operating lever.
This lever is pivotally connected to a pendent arm, secured to the under side
of the cover.
The rear end of said lever is pivotally connected to a vertically-
reciprocating operating rod, that passes through a horizontal guide-plate secured
over an inlet aperture of the top. The upper end of the rod is headed, and a
coil-spring is applied about said rod between said head and the horizontal guide,
so as to normally hold said rod up and the valve open. A suitable screw-
threaded nipple is applied about the edge of the opening to receive the screw-
threaded closing-cap. The head normally projects above the upper edge of the
screw-threaded nipple; but when the cover is applied to said nipple and screwed
down over the same, the said head is depressed and the valve firmly closed.
It will be observed from the foregoing description that when the cap is closed
the valve is also closed, and thus the contents of the can are fully protected
against being spilled by any accidental tipping of the can.
When it is desired to remove a portion of the contents of the can, the cap is
This loosening of said
first loosened to admit air into the interior of the can.
cap also permits the rod to rise under the action of the spring and thus opens
the valve at the lower end of the delivery-spout.
This invention is of particular use in such cans as contain dangerous explosive
liquids, such as naphtha, gasolene, or ether.
I contemplate constructing my said top in both square and round form, so
that it will be applicable to cans of corresponding form.
By the use of my invention the can is always perfectly sealed while the screw-
cap
is screwed down in position and cannot be unsealed without first unscrewing
said cap, thus admitting air to the can and at the same time opening the valve
of the delivery-spout.

I, FREDERICK LIED, of Columbus, County of Franklin, State of Ohio, United
States of America, Commercial Traveller, 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:-
-
This invention relates to storage-receptacles for liquids, and has more particular
relation to tops for oil-cans.
This invention consists of certain novel constructions, combinations, and
arrangements of parts which will be hereinafter more particularly set forth and
claimed..
In the accompanying drawings, forming part of this specification, Figure 1
represents a central vertical section through a can provided with my improved
top, Fig. 2 represents a bottom plan view of the same.
A in the drawings represents the can proper, B the top, and C the delivery-
spout. The lower end of this delivery-spout is provided with a flap-valve e, pivot-
ally secured thereto by means of a wire loop c. The face of this valve is provided
with a cork or other elastic packing 2, by means of which a perfectly tight joint
is formed between said valve and the lower end of the spout when said valve is
closed. The rear of said valve c is provided with an angular arm 3, having an
aperture e, the latter adapted to receive the reduced end of an operating
lever D. This lever is pivotally connected to a pendent arm d, secured to the
under side of the cover B. The rear end of the said lever D) is pivotally con-
nected to a vertically-reciprocating operating-rod d, that passes through a
horizontal guide-plate, secured over an inlet-aperture 61 of the top. The upper
end of the rod is headed as at , and a coil-spring is applied about said rod
between said head and the horizontal guide d², so as to normally hold said rod
up and the valve c open. A suitable screw threaded nipple 2 is applied about
the edge of the opening to receive the screw-threaded closing-cap E. The
head normally projects above the upper edge of the screw-threaded nipple ;
but when the cover E is applied to said nipple and screwed down over the same the
said head is depressed and the valve c firmly closed.
It will be observed from the foregoing description that when the cap E is
closed the valve c is also closed, and thus the contents of the can are fully pro-
tected against being spilled by any accidental tipping of the can.
When it is desired to remove a portion of the contents of the can, the cap E
is first loosened to admit air into the interior of the can. This loosening of said
cap also permits the rod to rise under the action of the spring and thus
opens the valve at the lower end of the delivery-spout.
This invention is of particular use in such cans as contain dangerous explosive
liquids, such as naphtha, gasolene, or ether.
I contemplate constructing my said top B in both square and round form, so
that it will be applicable to cans of corresponding form.
By the use of my invention the can is always perfectly sealed while the screw-
cap E is screwed down into position and cannot be unscaled without first unscrew-
ing said cap, thus admitting air to the can, and at the same time opening the
valve of the delivery-spout.
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
A top for a can comprising a top-proper, a delivery-spout for the same, filling-

page_text: aperture, closing-cap over the same, a hinged valve at the lower end of the spout,
and arm connected to said valve, a pivoted lever mounted upon the under side
of said top and engaging said arm, a vertically-reciprocating rod pivotally con-
nected to said lever, a head mounted on said rod, an aperture-guide surrounding
said rod and secured to the top, and a coil-spring surrounding said rod and bearing
against said guide and said head so as to normally force the rod upward and open
the valve when the closing-cap is loosened, substantially as described.
Dated this 2nd day of January 1899.
