Improvements in Pipes for Conducting and Raising Liquids such as
Acids, Alkalies, Beer, Parafine Oil, and the like.
I THOMAS LOCKERBIE of 27 Martins Lane in the City of London Engineer do
hereby declare the nature of this invention to be as follows:-
This invention relates to the raising and conduction of liquids by Hydro Pneumatic
pressure, and the pipes are constructed as follows.
Into a metal or other class of tube or pipe which is capable of withstanding strains
as well as direct pressure, I insert, glass, porcelain, earthenware or other tubes of like
material, but which from the nature of their construction or other causes would not
be capable of withstanding the pressure necessary to force the liquid to the required
height, or even if capable of withstanding such pressure would be liable to fracture
from the blow of a hammer or other cause of a similar nature.
The outer tube I make of sufficient cross sectional area to admit the inner tube and
to allow a space between the outside of the inner tube, and the inside of the outer
tube of an area equal to or in excess of that of the inner tube.
The liquid which by preference would be water used to compress the air in the
Hydro Pneumatic compressing chamber flows down through the space described
above, and the liquid to be raised passes upwards through the inner tube-Suitable
outlets and inlets at the top and bottom are provided for the purpose of keeping the
two streams from coming into contact.
I make arrangements to connect the different lengths of the inner tube by suitable
socket joints which can be placed in any part of the outer pipe, by this means it is
not necessary that the inner lengths of tubing should be the same as the outer
lengths.
Round tubes are best suited for this purpose but other forms may be adopted with
advantage.
The method of conducting liquids above described is mainly applicable to apparatus
where compressed air is used as the medium for forcing the liquid up, and any well
known compression may be used.

I THOMAS LOCKERBIE, Engineer, of 27 Martins Lane Cannon Street London in
the County of Middlesex, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This Invention relates to the raising and conduction of liquids by Hydro-Pneumatic
pressure, and the Pipes are constructed as follows:-
-
Into a metal, or other class of tube or pipe which is capable of withstanding strains,
as well as direct pressure, I insert glass, porcelain, earthenware or other tubes of like
material, but which from the nature of their construction, or other causes, would not
be capable of withstanding the pressure necessary to force the liquid to the required
height, or even if capable of withstanding such pressure, would be liable to fracture
from the blow of a hammer or other cause of a similar nature.
The outer tube I make of sufficient cross sectional area to admit the inner tube,
and to allow a space between the outside of the inner tube, and the inside of the
outer tube of an area equal to or in excess of that of the inner tube.
The liquid which by preference would be water, used to compress the air in the
hydro-pneumatic compressing Chamber, flows down through the space described
above, and the liquid to be raised passes upwards through the inner tube.
Suitable outlets and inlets at the top and bottom are provided for the purpose of
keeping the two streams from coming into contact.
I make arrangements to connect the different lengths of the inner tube by suitable
socket joints which can be placed in any part of the outer pipe; by this means it is
not necessary that the inner lengths of tubing should be the same as the outer
lengths.
In order that my Invention may be more easily understood, I will describe the
same more in detail by making reference to the accompanying drawing in which
similar parts are indicated by similar letters.
The drawing Fig. 1 shows my system of Glass lined tubing applied where an
ordinary hydro-pneumatic air compressor is used. A is a tank placed at any
convenient height above the point where the liquid is to be drawn.
B. is a pipe which conveys the compressing liquid to the annular space, round the
Glass tubes.
B₁ is the annular space referred to, and B' is the pipe which conveys the compressing
liquid to the hydro-pneumatic compressing Chamber C. DD are the pipes which
conveys the compressed air to the Casks or Vessels EE containing the liquid to be
raised. D' D are the branch pipes to each of a number of such vessels, and F. F.
are the glass tubes, which may be of any convenient length, and are joined together

page_text: by Sockets K or India rubber ferrules. F is a glass lined tube to convey the liquid
to be raised to the point of withdrawal G. on which a tap of any convenient descrip-
tion is fixed.
The rim M is made so as to fit between the ends of the tubes. As the pipes are
screwed together, the rim M makes the double socket rigid.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be carried out, I declare that what
I claim is :-
The construction of pipes having an inner tube inserted in such a manner as to
admit of a space between the inner and outer tubes, to be utilized for the purposes
set forth.
