page_text: I, JOHN GJERS, of Bournewood, Bournemouth, in the County of Hants, Engineer
and Ironmaster, do hereby declare the nature of this invention to be as follows:
My invention has reference to a construction of pumps comprising a siphon
having its legs (whether of equal or unequal length) at-an obtuse angle to one
another and connected by a chamber of more or less greater cross sectional area
constituting the bend or head of the siphon and wherein are arranged means for
imparting motion to liquid in such wise that it may be caused to flow in a practically
continuous manner in a given direction.
In one construction, the two siphon legs forming respectively the suction and
delivery pipes are connected at their upper ends by and through a cylinder in
the end covers of which there are bearings that carry a shaft adapted to be coupled
to a steam turbine, or other suitable motor, so as to be thereby driven at a suitable
speed according to requirement, but say at a speed of about 2000 revolutions per
minute, provision being made for lubricating the bearings of the pump shaft.
On that shaft there is an appliance in the form of a screw (which may be of any
suitable construction and may have one or more blades) adapted when the pump
shaft is driven to rotate with it and impart motion to the liquid within the chamber
so as to cause it to flow up the suction leg and down the delivery leg to any required
place, such a screw or worm revolving with an easy fit in a bored out part of the
cylinder which forms the head of the siphon by preference at a very high speed
say about 2000 revolutions a minute and may be driven direct by steam turbines
or by an increased or reduced speed; they may also be driven by reciprocating
quick running steam engines and the speed increased by friction or other gear.
By preference I keep the top of the syphon head slightly below the level of the
suction water so as to keep the syphon full of water ready for starting.
A siphon pump according to my invention may be constructed with more than
one shaft furnished with means for imparting motion to liquid as aforesaid.
In one such arrangement the chamber instead of being made cylindrical is in
cross section of oblong form with semicircular ends (i.e. sides of the chamber) and
is fitted with two shafts arranged with their axes parallel to one another and
adapted to be rotated in the same direction for the purpose of counteracting the
churning action on the water from the rotary motion of the screws each shaft being
furnished with a suitable screw or equivalent device rotating casily in two separately
bore out short cylindrical parts in the centre of the head of the syphon for imparting
motion to liquid for the purpose mentioned.

I, JOHN GJERS, of Bournewood, Bournemouth, in the County of Hants, Engineer
and Ironmaster, 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:-
My invention has reference to a construction of pumps comprising a siphon
having its legs (whether of equal or unequal length) at an obtuse angle to one
another and connected by a chamber of more or less greater cross sectional area
constituting the bend or head of the siphon and wherein are arranged means for
imparting motion to liquid in suchwise that it may be caused to flow in a practically
continuous manner in a given direction, as I shall now proceed to explain with
reference to the accompanying illustrative drawings wherein
Fig. 1 is a side elevation, partly in vertical section, showing one construction
of pump according to this invention applied to the pumping of water to a higher
level for irrigation or other purposes.
Fig. 2 is a part plan of the apparatus.
Figs. 3 and 4 show the pump alone, and to a larger scale than in Figs. 1 and 2,
Fig. being a longitudinal section, and Fig. 4 a cross section.
Figs. 5 and 6 show respectively in longitudinal section and cross section, a
modified construction of pump according to this invention.
In the construction shown in Figs. 1 to 4 inclusive, 1 and 2 are two legs forming
respectively suction and delivery pipes which are connected at their upper ends by
and through a cylindrical chamber 3 in the end covers 3 of which there are
bearings 4, that carry a shaft 5 adapted to be coupled to a steam turbine, or other
suitable motor, so as to be thereby driven at a suitable speed according to require-
ment, but preferably at a very high speed, say at a speed of about 2000 revolutions
per minute, provision being made for lubricating the bearings of the said shaft.
On the shaft 5 there is an appliance in the form of a screw or worm 6 (hereinafter
called a worm) which may be of any suitable construction and may have one or
more blades, though only one is shown, and which is adapted, when the pump
shaft is driven, to rotate with it and impart motion to the liquid within the
chamber so as to cause liquid to flow up the suction leg 1 and down the delivery
leg 2 to any required place, such worm revolving with an easy fit in a bored
out part 3 of the chamber which forms the head of the pump. The shaft may be
driven direct by a steam turbine, indicated diagrammatically at 7 in Fig. 1, or
indirectly by a reciprocating quick running steam engine, the speed being increased
by friction or other gear. The speed may however be higher or lower than that
mentioned.
8, 8 are ribs or vanes fixed in the chamber 3 at the ends of the worm for the
purpose of preventing rotary motion being imparted to the stream of water
flowing through the chamber, by the action on such stream of the worm 6. The
suction pipe 1 communicates with a supply of water 9 that is preferably of such
a height as to keep the syphon head full of water ready for starting. The delivery
pipe 2 is connected to a rising main 2ª by which the water can be delivered to a
higher level than the pump. 10, 10 are stop valves, and 11 is a fixed pivot to take
the thrust of the shaft 5.
In the example shown, the syphon pump is arranged in a chamber 12 in which
may be arranged the motor 7 for rotating the pump shaft 5.
With the arrangement described, when the worm 6 is rotated in the direction of
the arrows, water will be caused to flow up the suction leg 1 and down the delivery

page_text: leg 2 in an even and continuous manner and without abrupt change in direction,
and thence be delivered to any required place.
A pump according to my invention may be constructed with more than one
shaft 5 and worm 6 for imparting motion to liquid as aforesaid.
Figs. 5 and 6 show one such arrangement in which the chamber 3 instead of
being made cylindrical, is, in cross section, of oblong form with semicircular ends
(i.e. sides of the chamber), and is fitted with two shafts 5,5" with worms 6,6"
arranged with their axes parallel to one another, the said worms rotating easily
in two separately bored out short cylindrical parts 3", 3b the ends of which com-
municate with the enlarged flaring inner ends of the pipes 1 and 2. The two shafts
are rotated in the same direction so that any rotary motion that may be imparted
to the two streams of water by the worms, will be more or less neutralized by reason
of the two streams moving in opposite rotary directions where they come in
contact with each other. Fixed ribs or vanes 8, 8" may also, for a like purpose, be
provided at each end of each worm 6. In the example shown, each of the shafts
is provided at each end with a toothed or friction wheel 13 the several wheels being
driven in the same direction by toothed or friction wheels 14 in gear therewith and
fixed upon an engine crank shaft 15.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. Apparatus for raising and forcing liquids comprising suction and delivery
legs or pipes arranged at a large angle to one another and connected by a chamber
or head, and one or more screws or worms arranged to rotate in a bored out or
cylindrical part or parts of the said chamber or head and carried by one or more
driving shafts, substantially as hereinabove described.
2. The improved apparatus for raising and forcing liquids, constructed arranged
and operating substantially as hereinbefore described with reference to and shown
respectively in Figs. 1 to 4 inclusive, and in Figs. 5 and 6 of the drawings
annexed.
