TRUVIDIONAL SPECIFICATION,
Flushing Apparatus, with Moveable Siphon, for Water-closets.
WILHELM BEIELSTEIN of Bochum, Germany, Plumber, do hereby declare the nature
of this invention to be as follows:-
The siphon principle for emptying a vessel containing a liquid, as at present used
in water-closets, and in which the upper curve or head of the siphon is immersed in
the liquid, is far from satisfactory in the practical working. By the improved
construction, which is the object of this invention, a better application of the
above-named principle is attained as will be seen from the following description.
This flushing apparatus for water-closets, contains a siphon, the branches, of
which consists of pipes made partly of flexible material, preferably india-rubber
with wire screw shaped stiffening, in order to prevent any flattening of these
pipes when the head is let down into the liquid. The branches of the siphon
are fixed to a piece of metal, itself fixed to the bottom of the apparatus and
possessing 2 tubes one of which, crosses the bottom of the apparatus and is
terminated by a screw-threated portion, which is connected with the flushing-pipe
of the water-closet, whilst the other pipe, rests inside the apparatus, and its
lower orifice is a few centimeters removed from the bottom of the apparatus to ensure
the entrance of the water into the suction branch, of the siphon The metal piece
carries, moreover, a support which is forked in its upper part and upon which a lever
rests, with the help of a joint which allows free movement, in a vertical plane, to this
lever. This lever has, at the end of one of its arms a link in the form of a straight
slide and in which slides a small ring fixed to the siphon head.
The other arm of the lever carries a counter-weight and is coupled with the traction
lever by means of a connecting rod which is jointed at each of its ends.
In the normal position of the apparatus, that is to say when it is at rest, the head
of the siphon, submitted to the action of the counter-weight, by the agency of the
lever is always held above the level of the water, in the apparatus, whilst the suction
branch of this siphon is filled with water up to the same level.
As soon as the traction lever is pulled down by means of a draw-chain, the lever
arm, in connexion with the hoad of the siphon lowers itself, drawing the latter with
it, and completely submerging it: the water penetrates into the suction pipe the
curvature of the siphon and the descending pipe, to pass thence into the flushing-pipe
of the closet: the siphon in thus fetched and almost all the water contained in
the apparatus flows off naturally by the flushing-pipe even after the head of the
siphon has completely risen above the level, a movement which is ensured by
the counter-weight.
:
In the descending movement of the head of the siphon, the branches are materially
shortened owing to the curve which they described this explains why the link of
the lever take the form of a slide in order to compensate for the difference of length
which results, as compared with the rigid lever.
The lever action takes place in the direction of the length of the water-tank,
whereas the branches of the siphon, fixed on the metal piece are arranged transversely
to this direction. In this way, the head of the siphon or the curvature is supported
by its medial part and their can be no hindrance to its descending movement. This

page_text: descending movement may be prolonged to the required depth, even to the extreme
limit permitted by the flexible parts of the branches of the siphon. It follows that
if there is a proper number of coils in the metal wire and the wire is of suitable
strength, thus determining the dimensions of the flexible part of the siphon a radius
of curvature will be obtained sufficiently small to allow of the height of the water-
level in the apparatus being reduced to a minimum, without lessening in any
way the efficiency of the apparatus, a result which has not been hitherto
attainable.
The object of this invention is also attained when the flushing branch of the
siphon is alone fixed, in its place, to the metal piece whilst the suction branch
oscillates freely or is held without attachment by the bottom of the apparatus.
In this case, the suction branch has no need to be itself also furnished with a
moveable part.

Flushing Apparatus, with Moveable Siphon, for Water-closets.
I, WILHELM BEIELSTEIN, of Bochum, Germany, Plumber. 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 :-
The siphon principle for emptying a vessel containing a liquid, as at present used
in water-closets, and in which the upper curve or head of the siphon is immersed in
the liquid, is far from satisfactory in its practical working. By the improved
construction, which is the object of this invention, a better application of the
above-named principle is attained, as will be seen from the following description.
The flushing apparatus for water-closets, shewn in Figs. 1, 2 & 3 of the accompanying
Drawing, contains a siphon H, the branches h, h', of which consist of pipes made
partly of flexible material, preferably india-rubber with wire screw shaped stiffening,
in order to prevent any flattening of these pipes when the head is let down into the
liquid. The branches of the siphon are fixed to a piece of metal m, itself fixed to
the bottom of the apparatus and possessing 2 tubes one of which 7, crosses the
bottom of the apparatus and is terminated by a screw-threaded portion, which is
connected with the flushing-pipe of the water-closet, whilst the other pipe rests
inside the apparatus, and its lower orifice is a few centimeters removed from the
bottom of the apparatus to ensure the entrance of the water into the branch h, of
the siphon Fig. 2. The metal piece m, carries moreover, the support n which is
forked in its upper part and upon which the lever rests, with the help of a joint
which allows free movement, in a vertical plane, to this lever. This lever has, at
the end of one of its arms a link in the form of a straight slide u, and in which
slides a small ring fixed to the siphon head.
The other arm of the lever carries a counter-weight p and is coupled with the
lever Z, by means of the connecting rod o, which is jointed at each of
its ends.
In the normal position of the apparatus, that is to say when it is at rest, the head
of the siphon, submitted to the action of the counter-weight, by the agency of the
lever is always held above the level w of the water, in the apparatus, whilst the
branch h of this siphon is filled with water up to the same level w.
As soon as the lever Z is pulled down by means of a draw-chain, the lever arm,
in connexion with the head of the siphon lowers itself, drawing the latter with it

page_text: :
and completely submerging it: the water penetrates into the pipe h the curvature
of the siphon and the descending pipe h' to pass thence into the flushing-pipe of the
closet the siphon is thus fetched and almost all the water contained in the apparatus
flows off naturally by the flushing-pipe even after the head of the siphon has
completely risen above the level wa movement which is ensured by the
counter-weight p.
:
In the descending movement of the head of the siphon the branches are materially
shortened owing to the curve which they described this explains why the link u of
the lever take the form of a slide in order to compensate for the difference of
length which results, as compared with the rigid lever l.
The lever action takes place in the direction of the length of the water-tank,
whereas the branches of the siphon, fixed on the metal piece m are arranged
transversely to this direction. In this way, the head of the siphon or the curvature
is supported by its medial part and there can be no hindrance to its descending
movement. This descending movement may be prolonged to the required depth,
even to the extreme limit permitted by the flexible parts of the branches h and h¹ of
the siphon. It follows that if there is a proper number of coils in the metal wire and
the wire is of suitable strength, thus determining the dimensions of the flexible part
of the siphon, a radius of curvature will be obtained sufficiently small to allow of
the height of the water-level in the apparatus being reduced to a minimum, without
lessening in any way the efficiency of the apparatus, a result which has not been
hitherto attainable.
The object of this invention is also attained when the arm h¹ of the siphon is
alone fixed, it its place, to the metal piece m whilst the arm h oscillates freely or is
held without attachment by the bottom of the apparatus. In this case, the
siphon branch h has no need to be itself also furnished with a moveable part.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is-
A flushing apparatus for water-closets; with a siphon H made, totally or partially,
of a flexible material, and distinguished by the fact that the head of the latter
oscillates; perpendicularly to the plane of the siphon branches h and h¹ around at
least one of the siphon branches h¹ fixed to the bottom of the apparatus and is
completely immersed in the water by means of a lever device Z, o, l, with a
support at n, a counter-weight p and a slide-link u for the purpose of fetching the.
siphon, substantially as above described and shewn in the accompanying Drawing.
