Improvements in and relating to Illuminated Fountains.
I, LOUIS FAGUER, of 95 Boulevard Beaumarchais, Paris, in the Republic
of France, Engineer, do hereby declare the nature of this invention to be as
follows:
This invention relates to improvements in mechanism for effecting the continuous
circulation of the water in luminous or illuminated fountains.
On the bottom of the basin of a suitable fountain and communicating therewith
1 arrange a circular reservoir the lower portion of which is put into communication
with a rotary pump operated either directly or through suitable gearing preferably
by means of an electric motor. The said rotary pump is moreover, connected by
a suitable pipe to a pressure chamber preferably arranged within the aforesaid
circular reservoir and from which the jets are supplied. A third pipe connects
the said circular reservoir with the basin, but this last pipe opens into the said
basin at a higher level than that of the upper portion of the circular reservoir.
Another orifice connects the bottom of the basin with the circular reservoir. A
sufficient quantity of water is always left in the basin to keep the said circular
reservoir completely filled, so that, directly the motor is set in motion, the pump
may operate by drawing water from the said reservoir and pumping it into the
pressure chamber from whence it issues in jets by suitable nozzles or the like.
The level of water in the basin will gradually rise, the orifice connecting the
basin with the circular reservoir not being sufficiently large to pass all the water
thrown by the pump. This level will rise until it reaches the upper orifice in the
basin corresponding to the pipe whereby the water returns to the pump.
In order to ensure the satisfactory operation of the apparatus it is thus
necessary to arrange the relative sizes of the upper and lower orifices in the basin
which furnish communication between the said basin and the circular reservoir in
such a manner that :-
1. The volume of water passing through the lower orifice is less than that
issuing from the jets, in order that the level may rise in the basin as far as the
upper orifice.
2. The volume of water passing through the two orifices may together be equal
to that of the water issuing from the jets so that the level of water in the basin
may not rise above the upper orifice.
any water.
The fountain can thus operate indefinitely without it being necessary to add
When the motor is stopped, the pump stops and the water in the
basin runs through the lower orifice into the circular reservoir which it fills
so that the fountain is ready to work immediately the motor is started' afresh.
I also reserve the right, in certain cases, to do away with the upper orifice
and pipe in the basin and to enlarge the lower orifice connecting the said basin
with the circular reservoir so that this orifice may be large enough to conduct
the whole of the water issuing from the jets into the said reservoir.

COMPLETE SPECIFICATION.
Improvements in and relating to Illuminated Fountains.
I, LOUIS FAGUER, of 95, Boulevard Beaumarchais, Paris, in the Republic of
France, 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 relates to improvements in mechanism for effecting the continuous
circulation of the water in luminous or illuminated fountains.
The apparatus shown in the accompanying drawing illustrates the arrangement
of my improved fountain.
On the bottom of the basin of a suitable fountain and communicating therewith
I arrange a circular reservoir or chamber A the lower portion of which is put
into communication with a rotary pump B operated either directly or through
suitable gearing preferably by means of an electric motor E. The said rotary
pump is, moreover, connected by a pipe f to a pressure chamber F from which the
jets G are supplied. A third pipe h connects the chamber or reservoir A with
the basin, but this last pipe opens into the said basin at a higher level than that
corresponding to the level a of the circular reservoir or chamber A. Another
orifice m connects the bottom of the basin with the reservoir A. A sufficient
quantity of water is always left in the basin to keep the chamber A completely
filled, so that, directly the motor is set in motion, the pump may operate by drawing
water from the chamber A and pumping it into the pressure chamber F from
whence it issues in jets by the nozzles or pipes G. The level of water in the
basin will gradually rise, the orifice m connecting the basin with the chamber A
not being sufficiently large to pass all the water thrown by the pump. This level
will rise until it reaches the orifice n of the pipe whereby the water returns to
the pump.
In order to ensure the satisfactory operation of the apparatus it is thus necessary
to arrange the relative sizes of the upper and lower orifices, n and m, in such a
manner that :-
1. The volume of water passing through the lower orifice m is less than that
issuing from the jets, in order that the level may rise in the basin as far as the
upper orifice n.
2. The volume of water passing through the two orifices m and n may together
be equal to that of the water issuing from the jets so that the level of water in
the basin may not rise above the upper orifice n.
The fountain can thus operate indefinitely without it being necessary to add any
water. When the motor is stopped, the pump stops and the water in the basin
runs through the lower orifice m into the chamber A which it fills so that the
fountain is ready to work immediately the motor is started afresh.
I also reserve the right, in certain cases, to do away with the upper orifice and

page_text: pipe in the basin and to enlarge the lower orifice m connecting the basin with the
reservoir A so that this orifice may be large enough to conduct the whole of the
water issuing from the jets into the said reservoir.
I further reserve the right to apply my improved luminous fountain provided
with continuous circulation of the water to similar apparatus comprising coloured
discs.
The luminous fountain which I prefer to employ consists of a suitable basin the
bottom of which is provided with a lens adapted to project light into the jets of
water, from electric glow-lamps, arranged below the said lens on a disc or frame
which is preferably rotated through suitable gearing by the motor driving the
pump.
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:
First. An illuminated fountain in which the continuous circulation of the water
is effected by means of a reservoir communicating with the basin and with a pump
which pumps the water into a pressure chamber whence the jets issue, the water
required for supplying the jets being furnished, on starting the apparatus, by the
intermediate reservoir only, and, afterwards, when the regular working is established,
by the reservoir and by a pipe opening into the basin at a higher level than that of
the orifice whereby the basin communicates with the intermediate reservoir,
substantially as hereinbefore described.
Second. The improved apparatus constructed substantially as described with
reference to the accompanying drawing and operating as and for the purposes above
specified.
