Fig. 7 is a sectional view of the faucet detached, the section being taken on y y
Fig. 3, but showing the spigot in a position at right angles to that shown in
Fig. 5.
A. is the reservoir which is made preferably air tight, the only opening into the
same being that into which the faucet is inserted. The reservoir herein shown is
provided with a recess D in which the faucet, detached from the reservoir may be
conveniently and economically packed during the transportation. Into the opening
made in the face of the reservoir preferably within the recess D, is screwed the
automatic over-flow check faucet N, when the reservoir is to be used, the ring T
being preferably secured to the outside of said opening to thicken the material of
the reservoir at that point, so as to furnish a firm bearing for the threaded portion
of the faucet. This faucet is provided with a discharge passage a through which
the liquid flows and in addition with a smaller air admitting tube or passage
which passes from the inner to the outer end of the faucet and which provides
means for the supply of air to the interior of the reservoir to aid in the flow of the
liquid therefrom. Connected with the inner end of the passage is the hole b²
passing through the ring T and the face of the reservoir A and connected in turn
with the tube B in the interior of the reservoir which passes upward and terminates
at a point above the surface of the liquid in the reservoir.
The spigot or plug e of the faucet is provided with passages a¹ b¹ corresponding
in size and position to the passages ab of the faucet, and serving, when the spigot
is in proper position, to make the liquid discharge passage a a¹ continuous through
the length of the faucet, and the air admitting passage bb62B continuous from
the outer end of the faucet to a point within the reservoir above the surface of the
liquid. The faucet N is, moreover, provided with a secondary tube or passage "
preferably parallel and adjacent to the passage 62, running from the inner end of
the faucet to the spigot e and like is connected by means of the opening ³ with a
tube B' secured to the interior of the reservoir and like B terminating at a point
above the surface of the liquid. The spigot e is provided with a notch i so located

page_text: that when the spigot is in the position shown in Figs. 3 and 7 with the handle H at
right angles to the axis of the faucet and with both passages ab of the faucet cut off,
the said notch i shall be directly opposite the passage thereby forming a direct
communication between the outside air and the interior of the reservoir through the
tube B, but when, on the other hand, the faucet is in position for discharging the
liquid from the reservoir this communication with the outside air of the tube B¹ is
cut off, as shown in Fig. 5. The two air-admitting passages thus formed are entirely
separate and distinct from each other, and each admits air into the reservoir
independently of the other. The filling of the reservoir is accomplished through
the opening into which the faucet is afterwards secured, which opening is closed
during transportation of the reservoir, in any desired manner as by a screw
threaded plug.
The operation of my improved reservoir is as follows:-
The faucet N is first screwed in place with the passages 61 opposite the
openings through the face of the reservoir. When it is desired to draw liquid
from the reservoir the spigot is turned in the position shown in Fig. 5, and the
discharge of the liquid will be continuous until the level of the liquid in the vessel
to be filled reaches the end of the faucet. This cuts off the inflow of air through
the passage, when the discharge immediately stops. In Fig. 2 the tube B is
represented as terminating in an acoustic alarm C which may be constructed in any
desired manner to produce a sound, and which, as here shown, contains a reed E
partially closing a narrow opening so that a continuous sound is produced as long as
air flows into the reservoir through the tube B, but which of course stops with the
check of the inflowing air. This indicates to the as well as to the eye, when
the discharge of the liquid has been cut off.
car,
It sometimes happens that when the surface of the liquid in the vessel to be filled
has reached the end of the passage b, the impulse of the air rushing up into the
same, will cause water to wholly or partially fill the air tubes 6B, the water
remaining therein after the faucet has been shut off, so that when it is again desired
to draw liquid from the reservoir the presence of water in the air tubes may tend to
check for a moment the inflowing of the air necessary to break the vacuum within
the reservoir and start the flow of liquid therefrom. It is for this reason that the
secondary air passage already described is employed, by the use of which, when the
faucet is turned off, as shown in Figs. 3 and 7, air enters the interior of the reservoir
through the secondary passage ways 3B, thus breaking the vacuum within the
reservoir, so that when the faucet is again opened for the discharge of the liquid
the flow will at once begin, and will be again cut off automatically as before when
during the flow the communication of the outer air with the interior of the reservoir
through the secondary air passages ¹³ is cut off.
The faucet is preferably so constructed that the spigot is eccentric to the central
longitudinal axis of the faucet so that the liquid passage a¹ which passes transversely
through it, is out of centre, or in other words, is so placed that there is more
material on one side of the passage than on the other to close the faucet, for by this
means a discharge passage of larger size may obviously be employed in the faucet
and effectually closed by a spigot of a given size than if the spigot itself were
centrally located with respect to the faucet, as will readily be seen by reference to
Fig. 4.
An additional means of breaking the vacuum in the reservoir caused by
the stopping of the air tube B with water and causing the immediate flow of the
liquid, consists in providing the faucet with an opening near the outer end of the
same, and communicating with the air passage, so that when the level of the liquid
in the vessel to be filled closes the extreme end of the air passage 7 the effect of the
air still entering through the aperture y will be such as to cause bubbles of air, as
well as of water, to rise in the tube, and it has been found in practice that the air
thus admitted is sufficient to cause the liquid to flow immediately when the faucet is
again turned on. This means of breaking the vacuum may be used either alone or
in connection with the secondary air passages already described.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is
-
1. A. liquid reservoir provided with two interior air-tubes, in combination with an
automatic overflow-check faucet containing a liquid-discharge passage and two
separate and independent air-admitting passages connected with the air tubes in the
interior of the reservoir, all arranged and operating substantially as and for
the purposes described.
2. A liquid reservoir provided with two interior air-tubes, in combination with an
automatic over-flow check faucet containing a liquid-discharge passage and two air-
admitting passages connecting with the air tubes in the interior of the reservoir, one
of which passages passes to the outer end of said faucet, while the other terminates
at the spigot, and a notched spigot having suitable interior passages, substantially
as and for the purposes described.
3. A liquid reservoir provided with an automatic over-flow check faucet having
a liquid discharge passage and two separate and independent air-admitting passages,
one of which passes from the inner to the outer end of the faucet and the other of
which passes from the inner end of the faucet to the spigot, and having a spigot
provided with suitable openings corresponding to said passages, substantially as
described.
4. A liquid reservoir provided with a faucet having a spigot whose axis of
rotation is at one side of the longitudinal axis of the liquid passage through the
faucet and at rigat angles to said longitudinal axis, the said spigot being provided
with a liquid-passage passing transversely through it out of centre, whereby there.
is increased material on one side of the passage through the spigot to close the
faucet, substantially as described.
