AN IMPROVED PUMP, CHIEFLY DESIGNED FOR DISCHARGING FOUL LIQUIDS
AND THE LIKE, AND FOR RAISING WATER FOR BUILDING AND AGRICULTURAL
PURPOSES." A communication from abroad by Philipp Anton Fauler, of
· Freiburg, Germany.
PROVISIONAL SPECIFICATION left by the said William Robert Lake at the
Office of the Commissioners of Patents on the 9th February 1880.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "AN IMPROVED PUMP, CHIEFLY DESIGNED FOR
DISCHARGING FOUL LIQUIDS AND THE LIKE, AND FOR RAISING WATER FOR
BUILDING AND AGRICULTURAL PURPOSES." [A communication from abroad by
Philipp Anton Fauler, of Freiburg, Germany.]
The pumps used heretofore for building and agricultural purposes act imperfectly
in raising liquids which are viscous and charged with foreign bodies, in consequence
of bad joints, or of the obstruction of the valves, or defective packing of the piston.
In proportion to the great amount of force required the pumps are inferior in
effect, and are not applicable for raising liquid to different heights.
But the pump which forms the subject of this Invention avoids all the
inconveniences above stated, and works in a very efficacious manner.
The said pump has a strainer forming its inferior part, and fixed to a wooden
foot plank by means of screw-bolts; it is provided with four openings on its
circumference, through which openings the liquid to be raised enters the pump.
The valve-box with its adjutage, on which the cylinder is fixed by screw-bolts,
serves to form the base of the rising pipe, which is screwed thereon and provided
with a valve for drawing off the liquid contained in this pipe when the pump
ceases to work.
This rising pipe and the cylinder are provided at their upper end with loops
secured together by a screw-bolt.
In order to permit of changing the height of the rising tube within a given limit,
this rising pipe is composed of five or any other number of tubes or sections which
may be put together or one into the other.

page_text: A tight joint for these tubular sections is preferably produced by means of
caoutchouc rings placed into an annular groove made in each section of their upper
end. The tubes or sections may be very easily taken apart or replaced.
A mouth-piece is provided which has at its upper part two projections cast in
one piece with it. Between the latter there is laid a wrought iron ring for holding
a wooden discharging gutter.
In cases where the said mouth-piece and discharging gutter are not required, I
may use a mouth-piece consisting of a caoutchouc pipe, a conical cast iron adjusting
piece, and an outlet piece.
The said pump has a wooden piston-rod. I provide a screw-spanner to fit all of
the screws of the pump, and a willow basket to be placed upon the foot-plank only
when a liquid is to be raised which flows easily.
The aforesaid strainer and valve-box are closed at their upper extremities, with
the exception of round holes in the middle of their horizontal partition. Around
the orifices I place caoutchouc rings which constitute the seats for the valves, and
are held in place on the partition of the strainer and valve-box by cast iron rings
secured thereon by screw-bolts.
The suction-valves and the delivery-valve consists of a hollow cast iron
hemisphere, having attached to it by casting on its lower part a small wrought iron
bar which carries at its other extremity a cast iron ball.
In consequence of this construction of the valves the centre of gravity of the
latter is brought below their seats, thus obviating the necessity of a guide.
Should the pump occupy an oblique position, these valves produce always &
tight joint, and will never be obstructed even in raising pulpy impure or viscous
matter, that is to say, they allow the passage of all that may enter through the
openings of the strainer.
The piston consists of a hollow cast iron cylinder provided at the under side
with a boss. This piston has no packing, and has a diameter which is but very
slightly smaller than that of the cylinder in which it ascends and descends.
In the boss of the bottom of the piston there is cast a flat iron bar which is
twisted round at the middle of the height of the piston in the wooden piston-rod,
and united with the latter by means of a ferrule and pin.
This mode of connecting the piston with its rod affords a certain elasticity which
contributes to the easy working of the piston,
The pump is put into operation by raising and lowering the piston in the
cylinder by means of a wooden rod.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Robert Lake in the Great Seal Patent Office on the 9th
August 1880.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "AN IMPROVED PUMP, CHIEFLY DESIGNED FOR
DISCHARGING FOUL LIQUIDS AND THE LIKE, AND FOR RAISING WATER FOR
BUILDING AND AGRICULTURAL PURPOSES." A communication from abroad by
Philipp Anton Fauler, of Freiburg, Germany.
The pumps used heretofore for building and agricultural purposes act imperfectly
in raising liquids which are viscous and charged with foreign bodies in consequence

page_text: of bad joints, or of the obstruction of the valves, or defective packing of the piston.
In proportion to the amount of force required the pumps are inferior in effect, and
are not applicable for raising liquid to different heights.
But the pump which forms the subject of this Invention avoids all these incon-
veniences, and works in a very effectual manner.
My improved pump is illustrated in the accompanying Drawing, in which,―
Figure 1 is a front elevation of the said pump, and
Figure 2 is a horizontal section of the same on the line G, H, Figure 1.
Figure 3 is a vertical section on the line A, B, Figure 2.
Figure 4 is a horizontal section on the line C, D, and E, F, Figure 3.
Figures 5 to 9 represent various straight rising-pipes to be employed with the
said pump.
Figure 10 represents a discharging pipe or mouth-piece.
Figure 11 represents a wooden discharging gutter.
Figure 12 represents the screw-spanner for the pump, and
Figure 13 shews the willow basket hereinafter referred to.
6 represents a strainer forming the lower part of the pump, and fixed to the
wooden foot or base-plank by means of screw-bolts; this strainer is provided with
four openings on its circumference, through which openings the liquid to be raised
enters the pump.
The valve-box c with its. adjutage, on which the cylinder d is fixed by screw-
bolts, serves to form the base of the rising pipe f, which is screwed thereon and
provided with a valve n for drawing off the liquid contained in this pipe when the
pump ceases to work.
This rising pipe f and the cylinder d are provided at their upper end with loops
o, Figure 3, secured together by the screw-bolt e; in this manner the pipe f and
the cylinder d may be securely connected.
In order to permit of changing the height of the rising tube or pipe within a
given limit, this pipe is composed of five or any other number of tubes or sections
g, h, i, k, and l, Figures 5 to 9, which may be put together or one into the other.
A tight joint for these tubular sections is preferably produced by means of a
caoutchouc ring f' placed in the annular groove f³, made in each section at the
upper end. The tubes or sections may be very easily taken apart or replaced.
The mouth-piece m, Figures 1 and 3, is provided at its upper part with two
projections p¹, p¹, cast in one piece with it. Between the said projections there is
laid a wrought iron ring for holding the wooden discharging gutter q, Figure 11.
In cases where the mouth-piece and discharging gutter q are not required, I may
use a mouth-piece, as shewn in Figure 10, consisting of a caoutchouc pipe z, the
conical cast iron adjusting piece z¹, and an outlet piece z³.
represents the wooden piston-rod; 8, the screw-spanner to fit all of the screws of
the pump; and t, the willow basket to be placed upon the foot-plank a only when a
liquid is to be raised which flows easily. The joints are made by means of inlaid
caoutchouc rings. The strainer b and the valve-box c are closed at their upper
extremities, with the exception of a round hole or orifice in the middle of their
horizontal partition. Around these orifices I place caoutchouc rings u which
constitute the seats for the valves, and are held in place on the partition of the
strainer b and valve-box c by cast iron rings secured thereon by screw-bolts w.
The suction-valve x and the delivery valve x¹, each consist of a hollow cast iron
hemisphere, having attached to it by casting on its lower part a small wrought iron
bar which carries at its other extremity a cast iron ball.
In consequence of this construction of the valves the centre of gravity of the
latter is brought below the horizontal plane of the upper surface of their seats, thus
obviating the necessity of any guide. These valves moreover being freely suspended
afford a further advantage, for the reason that they can rise and fall without
producing any friction.
Should the pump occupy an oblique position, these valves produce always a tight
joint, and will never be obstructed even in raising pulpy impure or viscous matter,

page_text: that is to say, they allow the passage of all that may enter through the openings of
the strainer b.
The piston y, Figure 3, consists of a hollow cast iron cylinder provided on its
under side with a boss. This piston possesses no packing, and has a diameter
which is but very slightly smaller than the interior of the cylinder d, in which it
ascends and descends.
The application of a piston without any packing, and having a diameter, but
slightly smaller than that of the barrel in which it moves up and down, affords the
advantage that the amount of power required for moving the piston in working
the pump is far less than it is by the use of a piston provided with packing,
the quantity of liquid which may pass through the annular clearance between the
cylinder d and piston y being very small.
To the boss at the bottom of the piston there is cast a flat iron bar which is
twisted to the extent of ninety degrees at about the middle of the length of the piston,
is inserted in the wooden piston rod r, and is united to the latter by means of a
ferrule and pin (see Figure 3).
This mode of connecting the piston with its rod affords a certain elasticity
laterally, that contributes to the easy working of the piston, which will move
almost without friction in the cylinder d.
The pump is put into operation by raising and lowering the wooden rod r,
Figure 3, and raises one hundred litres to a height of four metres at an average
movement or speed of fifty five strokes of the piston in a minute, and at a length of
stroke from eighty to eighty five centimetres.
The total weight of a pump capable of raising the liquid to a height of four metres
does not exceed forty kilogrammes, not comprising the weight of the wooden
discharging gutter q and the willow basket; all constituent parts of the pump are
preferably tarred inside and outside.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it under-
stood that I claim,-
First. The construction of the hollow hemispherical valves freely suspended, and
having their centre of gravity beneath the horizontal plane of the upper surface of
their seats, as above set forth and for the purposes specified.
Second. The construction of the metal piston without packing, and united by
casting to the flat iron bar for connecting the wooden piston-rod to the body of the
said piston, which bar is twisted at the middle to impart to it elasticity, as above
set forth and for the purpose specified.
Third. A pump consisting of the parts constructed, combined, and operating
substantially as above set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Twenty ninth day of July, in the year of our Lord
One thousand eight hundred and eighty.
