Improvements in Tubes for Artesian Wells.
I, FRANCOIS ERNEST DIELTIENS, of 1, Avenue Isabelle, Antwerp, in the
Kingdom of Belgium, Architect, do hereby declare the nature of this invention to
be as follows:-
This invention relates to certain improvements in tubes for Artesian wells. The
tube is made of a series of cast iron pipes. The one end of each pipe has formed
on its exterior surface a series of circumferential grooves or corrugations and the
other end of each pipe has formed on its interior surface similar grooves or
corrugations. The end of the pipe having external grooves or corrugations being
the lower end, and inversely the end having the internal grooves or corrugations
being the top end. The joints between the pipes are made as they are driven.
A thin bed of clay or loam is placed in the swelling caused by the lower of the
then inserted in the
interior grooves or corrugations, the next length of pipe
pipe in position until the exterior grooves or corrugations ou it are opposite to
the internal grooves or corrugations in the pipe already in position. Melted
sulphur is then run into the joint until it completely fills the space between the two
pipes. When the sulphur sets a completely tight joint is made between the two
lengths of pipe which cannot be broken by the ordinary forces applied to such
pipes during the process of driving a well.
When the tube has been driven to the required depth, a top piece is added by
means of a similar joint and its top end is closed by a plate forming an hermetically
sealed joint in any suitable manner, suitable openings being provided for the
delivery of the water and also for the admittance of air.
When these well tubes have to be driven through quicksand I place in the
mouth of the tube a filtering apparatus made of any suitable metal and filled with
any suitable filtering material.

I, FRANCOIS ERNEST DIELTIENS of 1 Avenue Isabelle, Antwerp, in the
Kingdom of Belgium, Architect 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 certain improvements in tubes for Artesian wells, and
consists of the construction and combination of parts hereinafter described and
claimed.
Rafarning to the anomuanying drawing

page_text: section taken on the nine A-D
Fig. 3 is a section taken on the line C-D
Fig. 4 a section on the line E-F of Fig. 1, and
Fig. 5 is a view, drawn the actual size, of a sulphur-filled joint.
The tubes (a) forming the body of the well are surmounted by a section (a¹)
provided with openings (b) to admit the pump pipes (c) and the air pipe (d).
The said section is hermetically closed by a cast-iron cover (f).
The joint (J, J) is packed at its lower end with loam (T) over which the melted
sulphur (S) is poured.
The tube is made of a series of cast-iron pipes. One end of each pipe has formed,
on its exterior surface a series of circumferential grooves or corrugations, and the
other end of each pipe has formed on its interior surface similar grooves or
corrugations-the end of the pipe having external grooves, or corrugations, being
the lower end, and, inversely, the end having the internal grooves or corrugations
being the top end. The joints between the pipes are made as they are driven.
A thin bed of clay or loam (T) is placed in the swelling caused by the lower of
the interior grooves or corrugations; the next length of pipe is then inserted in
the pipe in position, until the exterior grooves or corrugations on it, are opposite
to the internal grooves or corrugations in the pipe already in position. Melted
sulphur (S) is then run into the joint until it completely fills the space (J, J¹)
between the two pipes.
When the sulphur sets, a completely tight joint is made between the two lengths
of pipe, which cannot be broken by the ordinary forces applied to such pipes
during the process of driving a well.
When the tube has been driven to the required depth, a top-piece is added by
means of a similar joint and its top end is closed by a plate forming an hermetically
sealed joint in any suitable manner, suitable openings being provided for the
delivery of the water and also for the admittance of air.
When these well-tubes have to be driven through quicksand I place in the mouth
of the tube, after the latter has been driven in place a filtering apparatus (H)
made of any suitable filtering material.
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. A tube, or pipe, for Artesian wells, characterised by annular grooves, or
corrugations, formed on its interior surface at the upper end, and on its exterior
surface at the lower end, the said grooves, or corrugations, forming a joint into
which is poured melted sulphur, held at the bottom by a layer or bed of loam, for
the purpose above specified.
2. A tube, or pipe, for Artesian wells, forming the upper portion thereof,
characterised by exterior grooves or corrugations, on the lower end, a cast-iron
cover hermetically closing its upper part and having openings in the side-walls to
admit the pump pipes and the air pipe, for the purpose above specified.
3. For wells intended to be driven through quicksand the securing of a filter at
the bottom of the well to prevent sand from entering the well, the whole as
described in the above Specification and shown in the accompanying drawing.
Dated this 2nd day of November 1895.
