Improvements in or connected with Hydraulic Apparatus for Raising
Water and other Motive Purposes.
I GEORGE JEVON, of 5 Hawthorn Road, Chad Valley, Edgbaston, in the City
of Birmingham, Gardener, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in the construction and arrangement of
apparatus whereby by a comparative small fall of water, the whole of the water
may be forced to a considerable height and there utilized for motive or other
purposes.
The precise details of the arrangement may be somewhat modified without
departing from its nature.
It consists broadly of an elevated cistern, to the underside of which is bolted a
cylinder, which I will call the first cylinder, and which is suitably supported on feet
or other base. Within this first cylinder is provided a sliding annular water
chamber, which also serves as a provision for an upper and lower air vessel; that
is, it consists of an outer and inner cylinder of different diameters and length, their
lower ends terminating with a water tight bottom piece, thus forming a watertight
annular compartment between the two cylinders. The inner cylinder stands higher
than the outer one. At about midway in the interior of the inner cylinder is
provided an air tight partition which blocks off the upper from the lower part, and
upon which may be placed a weight or weights. The exterior of this annular water
chamber slides freely in the said first cylinder.
Again. Suspended from the cistern or the upper end of the first cylinder, is an
inverted, cylindrical envelope, having its upper end closed, whilst its lower end
envelopes the exterior of the inner sliding cylinder of the water chamber, and
extending down into the water therein, thus forming an air vessel above the central
partition. Also a short cylinder extends downwards from the cistern, upon the
inside of the external cylinder of the water chamber. At the bottom of the first
cylinder is an outlet or branch communicating with a second cylinder, and provided.
preferably with a nonreturn valve. Within this second cylinder is provided an
inlet valve of any suitable form, but which may be of a slotted construction, so that
at each end of the stroke of the slide, it may be suddenly opened or closed as
follows:-The upper end of the second cylinder is covered and air tight.
Within this said cylinder is a double air vessel slide, which rises and falls within
the said cylinder.
It consists of a cylinder open at both ends, whose exterior slides freely upon the
inside of the said second cylinder. At or about midway in the interior of this air
vessel slide cylinder is a partition, which blocks off the upper from the lower part,
forming each into a separate air chamber. The second cylinder being part filled
with water, the said double air vessel slide floats therein, having an air space at the
upper part of the cylinder, and also a second air space between the surface of the
water and the underside of the interior mid partition. The lower end of this slide
is connected to the slot valve before mentioned, in such a manner that when the
slide is down the valve is open to admit a forced supply from the first cylinder,
which causes the said slide to rise. When the slide is nearly raised it suddenly
closes the valves, and again falls to the bottom by reason of its weight and the
elasticity of the air in the air chambers. From this second cylinder and at its
lower end is an outlet passage communicating with a delivery pipe, into which
a quantity of water is forced each time the slide in the second cylinder falls.
Between this delivery pipe and the second cylinder is provided a nonreturn valve.

page_text: In this delivery pipe in some cases I further provide one or more air vessels to
regulate and steady the outflow of water therethrough. In connection with the
outflow orifice of the delivery pipe for the purpose of obtaining rotary motion, I
may provide a waterwheel upon whose vanes or buckets the discharged water may
fall, and thereby give motion to a rotary shaft from which latter, machinery may
be driven, the water therefrom passing back into the cistern.
Briefly, the action of the apparatus is as follows:-
:-
Upon the supply cistern being charged the water therefrom falls into the annular
water chamber, and in and around the first cylinder, which causes the water chamber
to fall and thereby forces a quantity of water through the passage into the second
cylinder which causes the slide in the said second cylinder to rise, and in so doing
suddenly cuts off this flow. By this sudden cut off a rebounding action takes
place in the air chambers in the first cylinder .which causes the water chamber
therein to rise again, when the weight of the inflowing water again overcomes the
buoyancy of the chamber and it again descends repeating again the former process
and so on.
In like manner, the air which has been suddenly compressed in the
upper part of the double air vessel slide, within the second cylinder, drives
downwards the said slide, forcing a quantity of the water through the nonreturn
valve into the delivery pipe. Just however as the slide reaches the bottom of its
stroke, it again opens the slot inlet valve, which admits of the repeat supply from
the first cylinder.
After this manner the water is thus passed through the first into the second
cylinder, and thence into the delivery pipe from whence it is utilized as a motive
power in any suitable manner passing thence into the original cistern, or, in case
it has by this reached a lower level, it (the cistern) may be from time to time
recharged.

Improvements in or connected with Hydraulic Apparatus for Raising
Water and other Motive Purposes.
GEORGE JEVON 5 Hawthorne Road Chad Valley Edgbaston Birmingham
Gardener, 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 the construction and arrangement of
apparatus whereby by a comparative small fall of water, the whole of the water
may be forced to a considerable height and there utilized for motive and other
purposes.
It consists of an elevated cistern to the underside of which is attached a cylinder,
which I will call A and which is bolted to another cylinder B. Within these
cylinders A & B are two movable working air vessels; upper A1 & the lower B 1.
The exterior of the air vessels A 1 & B I are so made as to slide freely in the
cylinders A & B and also to be watertight.
Fitted around these two air vessels is a ring or rings so as to lessen the bareing
and make them work with greater case, the top of air vessel A1 is pierced with
holes so as to draw in a supply of air when riseing, the bottom being fitted with a
valve so arrainged as to blow off at certain pressure. Running from the cistern and
through the centre of the air vessel A. 1, is a tube A 2 terminated in a valve which
can only be shut by the upward action of the air vessel B 1.
Air vessel B 1 is pierced with holes at the bottom so as to draw in all air that is
forced under by the flow of water down pipe E. Their is also fitted to the bottom

page_text: of this air vessel a rod H, by which the motive power is produced. The same rod
also workes the sliding valves used for shutting and opening the different flows of
water in tubes E & F.
There is fitted on top of cylinder A two valves one for drawing in a supply of
fresh air if required, and the other is so made as to blow off at certain pressure, so
as to allow air vessel A1 to rise to whatever height it is required.
Tube E which runs from cistern to the underside of cylinder B is fitted on its
entrance to cylinder B with a sliding valve which opens or closes the flow of water
as required (said valve is worked by means of rod H) tube E then continues on and
is fitted on the underside of cylinder D and here it is supplied with a non-return
valve, this saine tube E is also fitted near the cistern with a tap, this said tap to be
used to start and stop the apparatus.
We will now follow the tube leading from the top of cylinder B to the underside
of cylinder C and will note that it is supplied on its entrance to cylinder C with
a non-return valve. Cylinder C is fitted with valves on top just the same as
cylinder A.
Inside cylinder C is a moving air vessel C 1, fitted the same as A 1 with holes in
top and valve in bottom and ring or rings around.
A return tube F is fitted to the bottom of cylinder C and leads from here to the
underside of cylinder D. We will also note that this tube F is at its lowest point
fitted with a sliding valve worked with the before-mentioned rod H. This sliding
valve closes or opens the flow of water as required this same tube F is also fitted with
a non-return valve just before its entrance into cylinder D.
Cylinder D is constructed on the same principle as cylinder C and fitted with
two valves on top, one for taking in fresh air and the other for regulating the
pressure.
Their is also fitted inside cylinder D an air vessel D 1 made same as A. 1 and fitted
with holes and valve.
We now come to the return tube L which runs upward and over the top of the
water wheel M.
Having now carefully explained the different parts of my said invention I will
now set it in motion.
First we will pour water into cistern which will fill into cylinders A & B forceing
air vessel A 1 up a little, and pressing B 1 down to the bottom of cylinder B and
will then fill down tube from top of cylinder B into cylinder C slightly raising air
vessel C1 the water will also fill down tube F as far as the sliding valve. The
water cannot get beyond this point until the upward action of the rod H moves said
sliding valve up and opens the passage.
The machine is now from this point to the top of cistern filled with water; we
will now turn the tap on which is fitted on tube E. The water from cistern will
then fall down pipe E and under air vessel B1 and will force air vessel B1 upward
thus bringing the water in cylinders A & B between two forces viz. that of the
compressed air in vessel A 1 and the upward action of air vessel B1 and so forces
the water with great power into cylinder C forcing air vessel C1 up very high,
air vessel B1 rising at this time and carrying with it the rod H which at a proper
regulated distance will move sliding valves in pipes E & F simultaneously, which
action will take all pressure from under air vessels A 1, B 1, & C 1, and they having
stored up a great amount of force (the passage now being opened by the action of
the sliding valves which opens one passage and closes the other) will now displace
the water into cylinder D and up tube L and into cistern again, and by this
action the air vessel B 1 will fall down to the bottom of cylinder B again, and so
the rod H will again move the sliding valves in pipes E & F and stop all outward
flow and open the inward flow from the cistern again, and so on by air vessel B1
moving up and down opening and shutting on and off the different flows of water
and eventually forceing all the water back into the cistern again we produce our
motive power.

page_text: 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. Movable air vessels worked by means of cold water and air.
2. The force of working a shaft by means of the motion of air vessels worked by
cold water and air.
3. The self motive action of the machine produced by the small fall of water.
