COMPLETE SPECIFICATION.
An Improvement connected with Well-pumps.
We, JOHANN KLEIN, Brick Works Proprietor, and BERNHARD BREUCH, Engineer.
both of Sieglar-on-the-Rhine, in the Empire of Germany, do hereby declare the
nature of this invention to be as follows:-
In pump wells of all kinds, but more particularly in artesian wells, it has been
found that the sand, which is carried along from the ground by the flow of the water,
very seriously affects the pump piston or plunger, and the valves as well as the
other movable parts, necessitating the renewal of same after a very short time.
According to the present invention, sand is prevented from being carried along
into the sensitive parts of the pump, by a specially constructed apparatus, herein-
after described, inserted in the well. This apparatus causes any sand which may,
after all, have been carried along with the water, to settle, and prevents its damag-
ing the working parts by abrasion or grinding.
The invention is illustrated in the accompanying drawing, which shews an
apparatus adapted to act as described, in vertical" section.
A box 1, which may suitably be made of cast iron, has at the top two open-
ings 2 and 3. The suction pipe 4 containing the working parts such as piston,
valves, etcetera, is connected with the opening 2.
In the connecting piece 41 of the pipe, there is inserted-for further safety-a
sieve 5, which catches, and allows to fall back, any grains of sand which may,
after all, have been carried along into the suction pipe.
With the opening 3 is connected the suction pipe 6, which is sunk in the ground;
and in the box, between the openings 2 and 3, a partition 7 is provided, the object
of which is to compel the sandy water to stream to the bottom of the box 1, when
the sand immediately settles down, and is prevented from being carried over to 2.
The action of the apparatus is plain:-The water coming out of the ground,
and pouring into the box through pipe 6 and the opening 3, and which naturally
still carries a considerable quantity of sand along with it, flows in a downward
direction in 1, which considerably facilitates the settling of the sand. The water
then gradually changes its flow into the opposite direction; whilst the sand, owing
to its weight, continues to fall, and settles in the bottom of 1. The collection of
sand and mud is then withdrawn by means of pipe S, and this operation is greatly
facilitated by the inclined formation of box 1.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, we declare that what we claim
is; :-
1. The improvement connected with well-pumps, consisting of the employment
and introduction on the suction pipe of the pump, of a box or chamber into which
the water enters from the top, and having a partition provided between the inlet
and outlet openings; substantially as set forth.

the pump, particularly as shewn in and set forth with reference to the drawings.
