PROVISIONAL SPECIFICATION.
Apparatus for Separating Air from Rain Water.
I, RUDOLPH HABERMANN of Manteuffelstr. Berlin in the German Empire,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object to liberate the air which is now carried with
heavy rain from the roofs of houses down the discharge pipes whereby the useful
cross sectional area of the water discharge is reduced and the water caused to
overflow.
The apparatus consists of a receiver intercalated in the rain water pipe. The
receiver is furnished with a plate perforated or not, or with another suitable organ
on which the rain water falls so as to liberate the air which escapes through an
aperture in the receiver.

COMPLETE SPECIFICATION.
Apparatus for Separating Air from Rain Water.
I, RUDOLPH HABERMANN of Manteuffelstr., Berlin, in the German Empire,
Engineer, 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 an apparatus to be interposed in the pipes by which the
rain water from the roofs of houses is discharged, and the object of the invention is
to separate the air from the rain water flowing from the roofs of houses through
the discharge pipes, before the water reaches the drains or sewers so as to render
these capable of carrying off the water with sufficient rapidity to prevent overflow
on to the streets and grounds and basements of houses.
In the drawing
Fig. 1 is a vertical section of the apparatus applied to a rain water discharge
pipe and Fig. 2 a similar view with the apparatus somewhat modified.
a is the rain water discharge pipe leading downwards from the roof of a house,
6 a receiver of any suitable form interposed in the discharge pipe a and fixed
thereto, ca plate of suitable form fixed within the receiver below the upper length
of discharge pipe a so that the down flowing water will strike upon it, d, an
aperture at the top of the receiver serving as outlet for the air separated from the
rain water.
The apparatus works as follows:-The rain water flowing down through the
upper length of discharge pipe a strikes upon plate c thereby changing the
direction of the flow of the water and for a moment retarding its velocity when
the accompanying air escapes from it. The water is distributed over plate c from
which it passes into the lower length of the discharge pipe free from air in which
state it does not require such a large cross sectional area of pipe or drain as when
the air has not been removed. In this way the efficiency of the pipe or drain for
carrying off the water is increased.
When the apparatus is applied to the discharge pipe at a great height from the
street level it may happen that air will again be taken up by the rain water after
it has once been separated therefrom to obviate which a bell or box shaped
...מ

page_text: receiver e (Fig. 2) is fixed over the top end of the lower length of the discharge
pipe so as to prevent access of air thereto.
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. An apparatus for separating air from the rain water flowing from the roofs of
houses, consisting of a receiver b interposed in the discharge pipe; of a plate c so
located in said receiver that the water flowing down the discharge pipe will strike
against it; and of an outlet d for the separated air, substantially as described with
reference to Fig. 1 of the drawing.
2. An apparatus for separating air from the rain water flowing from the roofs of
houses, consisting of a receiver b interposed in the discharge pipe; of a plate c so
located in said receiver that water flowing down the discharge pipe will strike
against it; and of an outlet d for the separated air, in combination with bell shaped
or inverted receiver e placed over the top end of the bottom length of the
discharge pipe, substantially as described with reference to Fig. 2 of the drawing.
