Improved Flushing Apparatus for Water Closets.
I, HERMANN KLEIN, of Mannheim, Germany, Manufacturer, 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 object of the present invention is a flushing apparatus for water closets
in which a float serves to start the syphon feeding the flushing pipe and to control
the supply cock.
The accompanying drawings represent, by way of example, one form of con-
structing the apparatus; Figure, 1, being a vertical section on the line, X-X,
Fig, 2; and Fig. 2, being a vertical section on the line, Y-Y, Fig. 1.
The improved apparatus comprises a water tank or cistern, k, at the bottom
of which is arranged a double siphon, a, a¹, connected to the flushing pipe, j.
A float, b, which, in the example illustrated, has the form of an elongated bell
or inverted trough, occupies the centre of the apparatus and is provided with
side rims or flanges, c, which ensure the hydraulic joint of the bell
To the centre
of the bell is secured a tube, e, which works piston tight in a tube, d, rising
from the bottom of the cistern, k. A chain, 7, attached to a hook, f, of the bell
at the end of the tube, e, and provided with a handle, m, passes through an
opening, o, in the cistern bottom and serves to actuate the float when it is desired
to flush the water closet. The float is further provided at one side with a ring, g,
with which there engages the end of a level, 4, which controls the plug of the
supply cock, i, terminating the supply pipe, n.
The arrangement described has for its object to obtain an energetic flush of
water by a simple pull on the chain, 7, which draws the float towards the bottom
of the cistern and thus sufficiently displaces the level of the water to start the
double siphon, a, a¹. The supply of the cistern is controlled by the descent of
the float which depresses the lever, h, and causes the opening of the cock, i.
The special form of float represented on the drawings, may, of course, be
replaced by an ordinary float provided with a pull chain passing in a piston or
around a pulley secured to the bottom of the cistern, and secured to a lever at
the upper part of the cistern, so that, in actuating the lever from the exterior
by means of a rod or chain, the float may be drawn to the bottom of the cistern
as in the example described, and a sufficient-lowering of the water obtained to
start the siphon.
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:-
(1) A flushing apparatus for water closets characterized by a float controlling
the water supply and provided with a pull device serving to draw it to the bottom
of the flushing cistern to start the siphon by the lowering of the water occasioned
by the descent of the float in the water, as set forth.
(2) A flushing apparatus for water closets characterised by a bell, controlling

page_text: the water supply, floating in the flushing cistern and provided internally with
a tube forming a piston in a second tube secured to the bottom of the flushing
cistern, a chain attached to the end of the first and passing through an opening in
the bottom of the second tube for lowering the bell in the water and causing a
lowering of the water sufficient to start the siphon, as set forth.
(3) A flushing apparatus for water closets constructed, arranged and combined
substantially as hereinbefore described with reference to the accompanying
drawings.
