Improvements in and relating to Oil and other Cans.
I, WASHINGTON WOOSTER WEBSTER, a citizen of the United States, residing
at No. 4950 Parkside Avenue, West Philadelphia in the County of Philadelphia,
and State of Pennsylvania, Merchant, do hereby déclaré the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and 'by the following statement:-
My invention has relation to an oil can provided with a movable pouring faucet
having a liquid discharge tube or spout controlled by an air tube or tubes and the
flow of liquid indicated by an acoustic signal located in the air tube or channel of
the faucet; and in such connection it relates particularly to the general con-
struction and arrangement of a can and of a pouring faucet revoluble or capable
of being swung about the can to establish a connection for filling and discharging
the contents of the can.
The principal objects of my invention are first, to provide a can with a pouring
faucet movable in different directions to permit of the filling of the can and of
the discharge of the contents thereof; second, to provide an efficient, reliable and
comparatively inexpensive pouring faucet for a can adapted to contain oil or other
fluids adapted to be swung about a standard to permit of filling the can and of
discharge of fluid from the can and in open position to control or check auto-
matically by air pressure the flow of the oil or other fluid; third, to provide an
oil can with a pouring faucet, comprising a standard having an air-tube connected
with the can and a Huid-way, a cap connected with the standard and provided
with an air-chamber and a liquid discharge spout and an inner air chamber
established between the standard and the cap with the can; fourth, to provide an
oil can with a pouring. faucet consisting of two members, one fixed and the other
movable about the same, an inner air chamber established between the said two
members and the movable member provided with an acoustic indicator operative
in only one position of the faucet; and fifth, to provide an oil can with a
movable pouring faucet having a liquid discharge spout or tube and one portion of
an air vent, chamber or tube; the movable member provided with a pin or pins
adapted to engage a stop or stops of the fixed member to limit the range of
movement of said movable member and an inner air chamber established between
said fixed and movable members, the construction being such as to permit of filling
the can through said faucet and then of discharge therethrough of the contents of
the can.
My invention consists of an cil can provided with a pouring faucet, constructed
and arranged in substantially the manner hereinafter 'described and claimed.
The nature and general features of my invention will be more fully understood
from the following description, taken in connection with the accompanying
drawings forming part hereof; and in which
Figure 1, is a top or plan view of a can with a movable pouring faucet,
embodying the features of my invention shown in application thereto, and the
same as shown being in such a position as to prevent discharge of fluid from
the can.

the acoustic indicator in the air vent tube of the outer air chamber.
Fig. 4, is a broken sectional top or plan view of Fig. 3; and
Figs. 5 and 6, are respectively perspective views of the hollow perforated
standard of the can, the cap adapted to be swung on the standard and with a
liquid discharge tube or spout and an outer air chamber, air veut and an acoustic
indicator adapted to produce a whistling sound during discharge of fluid from the
can, which ceases when the flow, of the oil or other, fluid stops, thereby indicating
that the vessel or other receptacle is empty.
The
Referring to the drawings a, represents an oil can of any suitable shape or
form., is a hollow perforated standard permanently fixed to the top a¹, of the
can, and preferably at or about one corner thereof and over an opening a²,
provided to receive or allow of the securing of the same about the opening to the
top a', of the can. The standard b, is provided with a vertical cylindrical
projection c, and with an orifice d, forming a fluid-way leading into the can a.
projection c, is of less diameter than the standard b, which is preferably made
conical in form and provided with an annular ledge or flange e. On this ledge or
flange e, is provided a ing for a purpose to be presently fully explained.
Extending through the wall of the standard b, and along beneath the top a¹, of
the can is á tube g, the upper opening h, of which is in the ledge or flange e, and
the other end having an opening i, extending to near the opposite internal end
of the can, beneath the top or roof a¹ thereof, as indicated in dotted lines in Fig. 1,
of the drawings.
Closely fitting the standard b, and projection c, adapted to be swung thereon
is a cap 1, with a liquid discharge tube or spout m, and an air tube or vent n.
The opening m', forming a fluid-way of the liquid discharge tube or spout m, in
the wall of the cap 1, is located complementally to the orifice d, of the standard b,
and is adapted to register therewith at one interval of its travel on the standard b,
as hereinafter more fully explained. 12, is a metal sheet or casing surrounding a
portion of the tube n, and brazed or soldered to the exterior surface of the liquid
discharge spout m, and cap 1, and constituting what is termed the "outer air
chamber" L., is on opening in the cap 1, from the outer air-chamber L, to an
inner air-chamber B, formed between the roof of the cap 1, and ledge or flange e,
of the standard b, and extending about half way around the same and arranged so
as to establish a direct communication with the tube g, extending into the can,
when the cap 7, is given a certain range of movement. In the air tube or vent n,
is located a whistle or reed p, adapted to be actuated by inrushing air from the
exterior to the interior of the can, or this whistle or reed p, may be located in
the opening, of the cap 1, between the inner air chamber B, and outer air
chamber L, as will be readily understood, and equally good results be obtained.
On the top of the cap l, and depending downwards therefrom are pins or lugs r
and adapted to revolve around therewith on the ledge or flange e, of the
standard b, until one or the other of said pins or lugs are brought into engagement
with a face for f, of the lug, whereby the rotation of the cap 1, on the
standard b, will be checked or stopped either to cut off the air supply or the flow
of the liquid through the discharge tube or spout m, according to the particular
position at the time of the pouring faucet.
To fill the can the faucet is caused to assume such a position as that a free channel
or passage-way is established between the spout or tube m, through the rear
opening m¹, thereof and the opening d, of the hollow standard 6, with the interior
of the can a, and the oil from a reservoir or container, not shown, is pumped
through a hose or tube introduced into the outer end of the spout or tube m, in
any suitable manner, until the required quota of fluid has been introduced into the
same.
The operation of the pouring faucet of my invention in its application to an oil.
or other fluid container or can, is as follows:-
In the shut off position, the cap l, of the faucet is swung upon the standard b,.

page_text: until it rests above the roof or top a', of the can a, and does not project materially
from the sides of the can. In this position one pin r, of the cap 1, rests against the
face of the lug f, and the opening, leading to the outer air chamber. L,
is directly back of said lug and closed thereby. The orifice m², of the liquid
discharge tube or spout m, and the complemental orifice d, of the standard b, will
not register in such position of the device. The cap is then swung outward at
nearly a right angle to one side of the can and with the same projecting beyond the
side of the can, for example, as illustrated in Fig. 3, of the drawings. In such
latter position, the pin or lug r¹, of the cap 1, will abut against the face f¹, of the
lugf, of the hollow perforated conical standard b, and the opening ", clearing said
lug, thereby establishing a direct open communication with the opening h, of the
tube g, extending through the standard b. In such position, a direct air connection
is established with the tube a, and of the inner air chamber B, with the outer air-
chamber L, and air tube or vent n. At the moment the pin or lug r², abuts against
the face f, of the lug f, the orifice m', in the cap l, communicating with the liquid
discharge spout m, registers with the orifice d, in the wall of the standard b, and a
direct communication between the interior of the can and the spout is thereby
established to permit of the free discharge of fluid from the can a, by the air
rushing into the can through the tubes or vents n and 9, and chambers L and B.
This inrushing air passing through a suitable acoustic signal, preferably a whistle,
such as illustrated in the drawings, operates said signal, which will sound during
the discharge of oil or other fluid from the liquid discharge spout or tube m.
When the oil in the vessel to be filled has reached a required height, which may be
determined by a gauge t, on the spout m, that allows the spout to project only a
certain distance below the top of the vessel to be filled, the oil will fill the end of
the air check and thereby stop the inflow of air therethrough. The acoustic signal
will then cease to sound. The can is then removed from communication with the
vessel and the cap I, swung around into a cut off position, as illustrated in Figs. 1
and 2, of the drawings. In this position, as hereinafter explained, no communication
exists between the air vents or tubes n and g, or of the oil spout m, and the interior
of the can, and hence no matter in which position the can is placed no oil will
escape from the spout. It is of course to be understood that the can is hermetically
sealed, or nearly so, and the can may be secured on the standard by a suitable air
tight washer v, fitting around and permanently secured to the cylindrical projection
thereof.
It will be manifestly obvious that as to minor details modifications may be made
and still be within the scope of my invention, as illustrated.
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 :-
