page_text: I HENRY EDWARD NEWTON, of the Office for Patents, 6 Bream's Buildings,
Chancery Lane, in the County of Middlesex, Civil Engineer, 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 is applicable to metal cans or vessels in which oil or other liquids
are put up for shipment and use, and from which the liquid may be drawn from
time to time in such quantities as may be required. The invention relates to that
class of faucet-bungs which are composed of a metal screw-bung provided with a
pouring-spout, a valve for closing said spout, and a screw-rod for operating the
said valve, the bung being reversible in the socket provided for it on the can, for
the purpose of enabling the spout to be brought within the can, for its protection
during transportation.
.
The faucet-bung which forms the subject of the present invention, differs from
others of the same class, in that it is received within a screw-threaded socket
which is sunk within the can, instead of being received in a screw-threaded socket
which projects from the outer surface of the can, and hence, when this bung is
reversed to bring the pouring spout within the can, there is nothing of the bung
or any of its appurtenances projecting from the exterior of the can; and it is the
construction hereinafter described which brings the bung within the body of
the can, which constitutes the principal feature of this invention. Another feature
of the invention consists in the construction of the socket for the reception of the
bung with an annular groove or enlargement of greater diameter than the screw-
thread, and into which a packing washer fits, and by which said washer is retained
in position and held in place when the bung is screwed down upon it.

page_text: In the accompanying drawing, Fig. 1 represents a portion of a can having the
improvements applied thereto, the bung being shown in the position which it
occupies when liquid is to be drawn from the can, and the valve being open, and—
Fig. 2 is a similar view with the bung shown in its reverse position to close
the can for shipment, and the valve being closed upon the seat over the pouring
spout.
Similar letters of reference designate corresponding parts in both Figures.
A designates a portion of the top of a metal can or other vessel which is
provided with a screw-threaded socket B. This socket may be made separate from
the can, and of sheet metal, and the screw-thread thereon may be formed by a
spinning operation, as is usual in attachments of this class. The socket B, if
made separate from the can, may have, at its outer end, an outwardly extending
flange b, which overlies the portion of the can top immediately around the hole
through which the socket projects, and is soldered to the can top. This socket B,
projects entirely within the can or vessel, and at its outer end is substantially flush
with the top or external wall of the vessel, so that when the can is closed for
shipment, as represented in Fig. 2, the faucet or attachment will have no projection
whatever beyond the top of the can. The socket B has, at its inner end, an
inwardly turned flange b¹, and is provided at the upper surface of said flange with
an outwardly projecting annular groove, b', larger in diameter than the screw-
thread of the socket, and serving to retain in place a leather or other packing
washer c, which rests upon the flange b¹.
C designates a reversible bung, which may also be of sheet metal, and which has
formed upon it, by spinning or otherwise, a screw thread which fits the screw
threaded interior of the socket B. This bung, C, is closed at the end c¹, and from
that closed end extends a pouring spout C₁. Within the bung C is a valve D,
which may be faced with leather or other material, and which closes on the closed
end of the bung over the entrance of the pouring spout C¹. This valve is
operated by a screw threaded rod D¹ working through the closed end c¹ of the
bung. As here represented, the screw threaded rod D¹ is permanently secured to
the valve D, and works in a nut formed in the hub c³ upon the closed end of the
bung C. As here represented, the valve D also controls a vent opening d in the
closed end of the bung.
When the can is filled for shipment, the valve D is closed tightly against the
closed end, c¹, of the bung C, and the latter is screwed into the socket, B, in
the position shown in Fig. 2, the bung being provided with a cross bar d²,
whereby it may be turned by the fingers. When the can is received by the con-
sumer, the faucet or can attachment is adjusted to the position shown in Fig. 1, in
order to provide for the draught of liquid from the can in quantity as desired.-
To effect this adjustment, the bung C, which was in the position shown in Fig. 2,
is unscrewed from the socket B, reversed in position, and again screwed into the
socket in the position shown in Fig. 1. When it is desired to draw liquid from
the can, the valve D may be adjusted as shown in Fig. 1, so as to open the passage
to the pouring spout, and to also open the vent opening, d.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondents, I declare that what I claim is :-
1. The combination with a can provided with a screw-threaded socket which
extends thereinto, and the outer end of which is approximately flush with the
exterior of the can, of the reversible bung C, closed at one end, and provided at
that end with a pouring spout, a valve contained within the bung, and closing on
the closed end of the bung over the pouring spout, and a screw rod working
through the closed end of the bung, for operating the valve, substantially as herein
described,

page_text: 2. The combination with a can provided with the screw-threaded socket B
extending within it, and at the inner end of which is an inwardly turned flange, b¹,
for supporting a packing c, and an annular groove 62, larger in diameter than the
screw-thread, for retaining the packing of the reversible bung C, closed at the end,
and provided with a pouring spout C¹³, the valve, D, within the bung, for closing
the pouring spout, and a screw-rod working through the closed end of the bung for
operating the valve, substantially as berein described.
