Improvements in Apparatus for Raising Liquid.
I, EUGENE ETEVE of 2 Boulevard de Strasbourg, Paris in the Republic
of France, Electrician, do hereby declare the nature of this invention to be as
follows:-
This hydraulic siphon is adapted to operate intermittently though at such
exceedingly short intervals that the supply is continuous as will be clearly under-
stood from the following description and by reference to the accompanying, drawings
in which the principle of the invention is illustrated and in which
Figure 1 is a vertical section of the apparatus,
Figure 2 an elevation, and
Figure 3 a plan.
As a continuation of the suction pipe a is arranged a box b containing valves c
and d the latter being the external valve controlling the supply of liquid from the
siphon.
The valve is arranged internally and adapted as required to open or close the
junction pipe or passage between the box 6 and regulating apparatus g.
From this regulator or governor the construction of which is described further
on and on the same level as the pipe starts the discharge pipe descending to a
somewhat lower level than that to which the suction pipe extends. Thus supposing
the suction-pipe descends 7 metres the discharge pipe will reach to a depth of
7 metres 50 or 8 metres.
The pipe is of somewhat smaller diameter than the suction pipe a and is provided
with a priming branch k.
The supply valve d closes by its own weight, a spring d being. merely provided
to prevent its being displaced by the rush of liquid.
The valve c oscillating with its spindle c is counter-balanced by a weight p
screwed to a lever arm of which the valve spindle c¹ constitutes the pivot. The
valve spindle extends, across the valve-box, and its rearward end,revolves. within a
tube or socket m closed at one end and secured to the valve box by solder or the
like, while its front end is supported and adapted to rotate within a similar tube or
socket n, similarly fixed to the box b. The air-tight packing of the valve spindle c¹
within this tube or socket n consists of a long sleeve o of, india-rubber or similar
material the backward end of which is tied to the tube n and the forward end to
the spindle c. This arrangement enables the stuffing-box to be dispensed with
and the friction and repairs connected, therewith to be avoided, while absolute
air-tightness is ensured to the operating parts without appreciable resistance
or strain.
The weight is adapted to slide upon its lever so as to facilitate the control of
the valve. The lever 7 is arranged to operate between two springs which are
controlled or adjustable by set-screws v v².
The governor or regulator g is a cylindrical casing erected vertically and having
its, top and bottom plates formed of, diaphragms or membranes t¹ of india-rubber
or other like clastic material; or of thin metal sheets which may or may not be
corrugated.
The apparatus constructed as described is placed in a tank or reservoir of
given dimensions. For this purpose the governor g is provided with legs so
that the bottom plate t may have full freedom. An orifice y is provided where
the raised water is to be drawn off directly, but this opening is of course dispensed
with where the siphon is employed for feeding another adjacent elevating
apparatus.

page_text: The operation is as follows:
Assuming that the siphon has been primed the water or liquid sucked in at a
passes through the box 6, tube f and regulator 7 and issues through the discharge
pipe h.
This pipe owing to its small diameter affords but a comparatively small outlet.
Hence the pressure within the box 6 increases and the valve c closes, while at the
same time the valve d opens and the suction process continues. By this time the
pipe is partially evacuated and is causing a certain depression within the regulator;
and on the other hand the pressure within 6 has also decreased with the result that
the valve c opens and the suction is continued through the regulator while the
valve d is closed. The diaphragms t t then take up their positions again and the
same series of operations is repeated. It should however be observed that the
interval of time between each succession of operations and the following one, is
exceedingly short, so much so that the number of pulsations of an apparatus of
about the size of the views in the drawing will be from 200 to 300 per minute. Thus
it will be understood that a practically continuous jet is obtained at d.
This improved siphon is applicable wherever liquid is to be drawn from a
depth or raised, for example for irrigating purposes. for the supply of feed-
water and the like. It being adapted to operate without the use of motive
power and requiring no surveillance or repairs its use will be found extremely
economical.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Raising Liquid.
1, EUGENE ETEVE of 2 Boulevard de Strasbourg, Paris in the Republic of
France, Electrician, 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 hydraulic siphon is adapted to operate intermittently though at such
exceedingly short intervals that the supply is continuous as will be clearly under-
stood from the following description and by reference to the accompanying drawings
in which the principle of the invention is illustrated and in which
Figure 1 is a vertical section of the apparatus,
Figure 2 an elevation, and
Figure
a plan.
As a continuation of the suction pipe a is arranged a box b containing valves c
and d, the latter being the external valve controlling the supply of liquid from the
siphon.
The valve c is arranged internally and adapted as required to open or close the
junction pipe or passage f between the box and regulating apparatus g.
From this regulator or governor y the construction of which is hereinafter
described and on the same level as the pipe starts the discharge pipe / descending
to a somewhat lower level than that to which the suction pipe extends. Thus,
supposing the suction-pipe descends seven metres the discharge pipe will reach to a
depth of seven and a half or eight metres.
The pipe is of somewhat smaller diameter than the suction pipe a and is
provided with a priming branch k.
The supply valve d closes by its own weight, a spring d¹ being merely provided
to prevent its being displaced by the rush of liquid.
The valve c oscillating with its spindle is counter-balanced by a weight p
secured to a lever arm of which the valve spindle e' constitutes the pivot. The
valve spindle extends across the valve-box and its rearward end revolves within

page_text: a tube or socket m closed at one end and secured to the valve-box by solder
or the like, while its front end is supported and adapted to rotate within a
similar tube or socket » similarly fixed to the box b. The air-tight packing of
the valve spindle c within this tube or socket consists of a long sleeve o of
india-rubber or similar material, the backward end of which is tied to the tube n,
and the forward end to the spindle c'. This arrangement enables the stuffing-box
to be dispensed with and the friction and repairs connected therewith to be
avoided, while absolute air-tightness is ensured to the operating parts without
appreciable resistance or strain.
The weight is adapted to slide upon its lever so as to facilitate the control of
the valve. The lever is arranged to operate between two springs which are
controlled or made adjustable by set-screws ve'.
"
The governor or regulator g is a cylindrical casing erected vertically and having
its top and bottom plates formed of diaphragms or membranes t t' of india-rubber
or other like elastic material, or of thin metal sheets which may or may not be
corrugated. These diaphragms are kept apart by a large spiral spring & of a power
to be determined by practical experiment.
The apparatus constructed as described is placed in a tank or reservoir of
given dimensions. For this purpose the governor g is provided with legs so that
the bottom-plate ¹ may have full freedom. An orifice y is provided where
the raised water is to be drawn off directly, but this opening is of course
dispensed with where the siphon is employed for feeding another adjacent
elevating apparatus.
The operation is as follows:-
Assuming that the siphon has been primed the water or liquid sucked in at a
passes through the box b, tube and regulator g and issues through the discharge
pipe h.
This pipe h owing to its small diameter affords but a comparatively small outlet.
Hence the pressure within the box bincreases and the valve c closes, while at the
same time the valve d opens and the suction process continues. By this time the
pipe is partially evacuated and is causing a certain depression within the regulator;
and on the other hand the pressure within 6 has also decreased with the result that
the valve c opens and the suction is continued through the regulator while the valve d
is closed.
The diaphragms t t¹ then take up their positions again and the same series of
operations is repeated. It should, however, be observed that the interval of time
between each succession of operations and the following one, is exceedingly short,
so much so that the number of pulsations of an apparatus of about the size of the
views in the drawing will be from 200 to 300 per minute. Thus it will be under-
stood that a practically continuous jet is obtained at d.
This improved siphon is applicable wherever liquid is to be drawn from a depth
or raised, for example, for irrigating purposes, for the supply of feed-water, and the
like. It being adapted to operate without the use of motive power, and requiring
no surveillance or repairs its use will be found extremely economical.
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 :-
1. In an apparatus for raising water the combination with a tank or reservoir of
a siphon formed by two pipes such as a and the longer one h of which is of smaller
diameter than a for the purpose, of discharging the liquid into the tank or reservoir
in a practically continuous jet substantially as specified.
2. The combination with the tank or reservoir of the siphon arrangement com-
prising the two pipes a and h between which are arranged a valve box such as b
provided with a cut off valve c and supply valve d, the diaphragm regulator g con-
nected with the said valve box by a branch pipe the whole operating substantially
as described and illustrated in the accompanying drawing.

page_text: 3. The combination and arrangement of parts constituting the complete apparatus
substantially as described and illustrated in the accompanying drawings.
