I, FRIEDRICH FERDINAND WILHELM LUDWIG MÜLLER, of 64 Alterwall,
Hamburg, in the Empire of Germany, Hardware Manufacturer, do hereby declare
the nature of this invention to be as follows:-
This invention relates to the flushing arrangements of water-closets.
It is well known that water closet basins when of earthenware or china are very
liable to become damaged or deformed during the process of burning especially at
the inwardly curved upper part that acts as a baffle or deflecting piece and is
arranged in front of the water inlet to the basin. It has not been possible hitherto
to overcome this difficulty and my invention has reference inter alia to an improved
construction of said baffle or deflecting pieces such as will not be liable to the
objection above referred to.
In the examines
illustrative drawings
Figs. 3 and 4 are detail views showing the shell and its attachment to the
basin.
The part a that serves for distributing the flushing water is not, as hitherto
usual, made integral with the basin b; but is made of elastic material such as india
rubber, and is secured to the basin-wall in front of the mouth of the water-delivery
piped by bolts c.
At the lower part of the piece a there are formed projections a' which form openings
at the sides and bottom (Fig. 4) of the part a for the flushing-water to rush through
into the basin b.
In order to keep the elastic material in the desired shape, and to cause it
to press equally upon the basin wall, a platef is provided, which is passed upon the
bolts c and screwed down thereby upon the piece a.
With this new arrangement the width of the discharge openings at the sides and
the bottom of the piece a of elastic material can be regulated by means of the
bolts c, exactly in accordance with the quantity of water used or with its
pressure.
.
At the front of the basin the groove formed by the incurved rim h terminates and
there is inserted in the said rim a piece of india rubber, which is angular in cross
section. One portion of this piece corresponds to the circular form of the basin
and projects a little above it whilst another portion j is forced into a dovetailed
groove the wider part of which is in the interior of the basin-wall.
The groove in the basin-wall for the india-rubber piece 9 makes it necessary to
strengthen there the underpart of the basin rim to an extent dependent on the
length of the piece g.
In consequence of this arrangement, the discharged water rushing through the
said opening of the piece a into the basin, and streaming along and underneath its
incurved rim will come against the piecey and be thereby driven down, thus
causing a much more thorough flushing at this part of the basin than has hitherto
been possible. Compared with the methods of flushing water-closets used up
10 now, this arrangement possesses great sanitary advantages.

I, FRIEDRICH FERDINAND WILHELM LUDWIG MÜLLER, of 64 Alterwall,
Hamburg, in the Empire of Germany, Hardware 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:-
This invention relates to the flushing-arrangements of water-closets.
It is well known that water-closet basins, when of earthenware or fire-clay are
very liable to become damaged or deformed during the process of burning especially
at the inwardly curved upper part or shell that acts as a baffle or deflecting piece
and is arranged in front of the water inlet to the basin. It has not been possible
hitherto to overcome this difficulty and my invention has reference inter alia to an
improved construction of said baffle or deflecting piece, such as will not be liable to
the objection above referred to.
Referring to the illustrative drawings filed with my Provisional Specification,
Fig. 1 is a vertical section and
Fig. 2 a plan, partly in section, of a water-closet basin made of earthenware
or fire-clay and provided with a flushing arrangement according to this invention;
and
Figs. 3 & 4 are detail views showing a shell or baffle, and its mode of attachment
to the basin.
The part a that serves as a baffle or shell for distributing the flushing-water is
not, as heretofore usual, made integral with the basin b; but is made of elastic
material, such as india-rubber, and is secured to the basin-wall, in front of the
mouth of the water-delivery pipe d therein by bolts c.
At the lower part of the baffle or shell a, (hereinafter called a baffle), there are
formed projections a¹ which serve to produce openings at the sides and
bottom (Fig. 4) of the baffle through which the flushing-water can rush into the
basin b.
In order to keep the elastic material forming the baffle a in the desired shape,
and to cause it to press equally upon the basin-wall, a plate f is provided through
which the bolts c extend and which is forced against the baffle by the nuts on the
said bolts.
With this arrangement the width of the discharge openings at the sides and the
bottom of the baffle a can be regulated, by means of the bolts c, exactly in
accordance with the quantity of water to be used at each flushing operation or with
the pressure of the water.
At the front of the basin the groove formed by the inwardly curved rim h
terminates, and there is inserted in the front portion or rim of the basin a piece g
of india rubber, which is of angular form in cross-section. One portion of this
piece corresponds to the circular or curved form of the basin and projects a little
above it; whilst the portion j is forced into a dovetailed groove the wider part of
which is in the interior of the basin-wall. In consequence of this groove in the
basin-wall for the piece g of india-rubber, it is necessary to strengthen the under-
part of the front portion of the rim of the basin as shown to an extent dependent
on the length of the said deflecting piece.

page_text: In consequence of the arrangement described, the flushing water upon rushing
through the opening at the sides of the baffle a into the basin and streaming along
and underneath its inwardly curved rim h will come against the piece 9 of india-
rubber and be thereby deflected downward, thus causing a much more thorough
flushing at this part of the basin than has hitherto been possible. Compared with
the methods of flushing water-closets heretofore used, this arrangement possesses
great sanitary advantages.
The india-rubber piece 9 is chiefly provided in order to prevent the flushing-
liquid, the velocity of which is very great, from passing between the water closet
seat and the basin wall. Besides fulfilling this object it protects the upper edge or
rim of the basin from being damaged by letting the seat fall down violently
thereon.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. A water-closet basin constructed with a baffle or shell made separate from the
basin and secured over the delivery passage for flushing liquid in such a way as to
form lateral exit or discharge openings substantially as described and shown for the
purpose specified.
2. A water closet basin wherein the inwardly turned rim h terminates on each
side near the front of the basin and this part of the basin is provided with a piece g
of material such as india rubber arranged to project above the upper rim or edge of
the basin substantially as described and shown for the purpose specified.
3. The improved water closet basin with flushing and cushioning arrangements
hereinbefore described with reference to and shown in the drawings.
Dated this 7th day of December 1894.
