page_text: Closures for Cans and other Vessels.
A communication from abroad by JOHN RAU, a citizen of the United States, residing
at 333 Center Street, City of Chicago, in the County of Cook and State of
Illinois, one of said United States, Mechanic.
I, WILLIAM FAIRBURN HART, of 1, East Parade, Leeds, in the County of York,
Patent Agent, do hereby declare the nature of this invention to be as follows:-
The present invention relates to that class of closures which are so incorporated
with the discharge spout or nozzle of the vessel that said spont or nozzle serves as a
handle for operating the closure, and in which the closure is of such a nature that the
vessel requires but one opening through which it may be filled and emptied, and in
which opening the associated parts going to make up the closure and spout are
arranged.
The vessel, which may be of any desired construction, material and shape, is provided
with a single opening in which is placed and secured a tube which projects some
distance into the interior of the vessel. The tube is provided at its outer end with a
flange resulting in a shoulder, and within the vessel it is provided in its side with an
opening. Fitting within this tube is a second tube provided with an opening, so
located that by a rotary movement of one tube within the other the openings may be
brought to register with each other and permit liquid to flow either inward or outward
through said openings, and in order to prevent liquid from either entering or leaving
the vessel through any other passage, the inner end of either one or both of the tubes
is closed. As for instance the inner tube may be closed and the outer end of the
inner tube is left open, and may be preferably provided with a lip for directing the
flow of liquid as it is discharged.
Secured to the second named tube is a finger which engages the shoulder of the
first named tube and prevents relative end wise movement of the tubes, while permitting
their: relative rotary movement. A suitable stop is also provided for limiting this
relative rotary movement and preventing further movement as soon as the tubes
have reached such relative positions that the openings register. This stop consists
of a pin carried by the second named tube and adapted to come in contact with
the shoulders formed on the first named tube by cutting away a portion of the
top side of its flange. In order to compensate for wear, resulting from the frictional
contact of the meeting surfaces of the two tubes, they are preferably slightly tapered.
It will be understood that in order to either fill or empty a vessel provided with a
closure as above described, the second named tube is turned until the openings register,
and that when the contents of the vessel are to be protected from contact with the
atmosphere the parts are placed in such positions that each tube closes effectually the
opening through the other.

page_text: A communication from abroad by JOHN RAU, a citizen of the United States of
America, residing at 333 Center Street, Chicago, in the County of Cook, and
State of Illinois, one of said United States, Mechanic.
I, WILLIAM FAIRBURN HART, of 1 East Parade, Leeds, in the County of York,
Patent Agent, 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 :-
The present invention relates to that class of closures which are so incorporated
with the discharge spout or nozzle of the vessel that said spout or nozzle serves as a
handle for operating the closure, and in which the closure is of such a nature that the.
vessel requires but one opening through which it may be filled and emptied, and in
which opening the associated parts going to make up the closure and spout are
arranged.
The invention consists in certain features of novelty that are particularly pointed
out in the claims hereinafter, and in order that it may be fully understood I will
describe it with reference to the accompanying drawing, which is made a part
hereof, and in which :-
$
Figure 1 is a side elevation of a vessel with the improved closure applied thereto.
Figure 2 is a plan thereof.
Figure 3 is an axial section of the improved closure on a larger scale.
A represents the vessel, which may be of any desired construction, material and
shape. It is provided with a single opening in which is placed and secured a tube B
which projects some distance into the interior of the vessel. The tube is provided at
its outer end with a flange resulting in a shoulder b, and within the vessel it is provided
in its side with an opening b¹. Fitting within this tube is a second tube C provided
with an opening c, so located that by a rotary movement of one tube within the other the
openings b and c may be brought to register with each other and permit liquid to flow
either inward or outward through said openings, and in order to prevent liquid from
either entering or leaving the vessel through any other passage, the inner end of either
one or both of the tubes is closed. As shown in the drawing it is the inner tube, but
this is merely illustrative, and the invention in its broadest aspect is not limited thereto.
The outer end of the inner tube is left open, and is preferably provided with a lip C'
for directing the flow of liquid as it is discharged.
Secured to the tube C is a finger D which engages the shoulder 6 of the tube B and
prevents relative endwise movement of the tubes, while permitting their relative rotary
movement. A suitable stop is also provided for limiting this relative rotary movement
and preventing further movement as soon as the tubes have reached such relative
positions that the openings b and c register. As shown in the drawing, this stop
consists of a pin E carried by the tube and adapted to come in contact with the
shoulders e formed on the tube B by cutting away a portion of the top side of its
flange. In order to compensate for wear, resulting from the frictional contact of the
meeting surfaces of the two tubes, they are preferably tapered slightly, as shown in
the drawing.
It will be understood that in order to either fill or empty a vessel provided with a
closure as above described, the tube C is turned until the openings 61 and c register,
and that when the contents of the vessel are to be protected from contact with the
atmosphere the parts are placed as shown in Figure 3 of the drawing, in which positions
each tube closes effectually the opening through the other.
Having now particularly described and ascertained the nature of my said

page_text: invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. The combination with the vessel, of a tube secured in an opening in the vessel,
said tube extending into the vessel and another tube open at its outer end and rotatively
mounted within the first tube, one of said tubes being closed at the inner end, and both
of said tubes within the vessel being provided with openings adapted to be brought to.
register with each other by a rotary movement of the inner tube, and a finger, or its
equivalent, outside of the vessel on one of the tubes in constant engagement with a
flange on the outside of the other tube to prevent lateral movement, said finger being
removable whereby the inner tube may be removed from the outer tube from the
outside of the vessel, substantially as set forth.
2. The combination with a vessel, of a tube secured in an opening in the vessel,
said tube extending into the vessel and another tube open at its outer end and rotatively
mounted within the first tube, one of said tubes being closed at the inner end, and both
of said tubes within the vessel being provided with openings adapted to be brought to
register with each other by a rotary movement of the inner tube, a pin on one of the
tubes adapted to engage with shoulders on the other tube for limiting the rotary
movement of the inner tube and a finger, or its equivalent, outside of the vessel on one-
of the tubes in constant engagement with a flange on the outside of the other tube to
prevent lateral movement, said finger being removable whereby the inner tube may
be removed from the outer tube from the outside of the vessel, substantially as set
forth.
3. The combination with a vessel having an opening, of the tube B secured in said
opening and projecting into the vessel, the tube fitting within the tube B and capable.
of movement relatively thereto, one of said tubes being closed at its inner end and both
being provided with openings which are adapted to be brought to register with each
other by a movement of the inner tube, a shoulder formed on one of said tubes,
and a finger carried by the other and engaging said shoulder for preventing the
withdrawal of the inner tube, said inner tube being left open at its outer end for the
discharge of the contents of the vessel, substantially as set forth.
4. The combination of a vessel having an opening, the tapering tube B secured in
said opening and having a shoulder b and the opening 61, the latter located within the.
vessel, the tapering tube C having opening c, fitting within the tube B and left open
at its outer end for the discharge of the contents of the vessel, the finger D carried by
the tube C and engaging the shoulder b, the pin E carried by the tube C,and shoulders
on the tube B for engaging the pin E and limiting the relative rotary movement of
the tubes, the inner end of one of the tubes being closed, substantially as set forth.
