of the Commissioners of Patents on the 31st March 1879.

Syphon traps have heretofore been held to be the best means for preventing
noxious or unpleasant gases from rising out of vertical or inclined soil or drain
pipes for the abduction of impure fluids or substances. In practice, however, it is
found that such traps become stopped up easily, and the object of this Invention
is mainly to do away with this evil.
For this purpose the syphon trap is made movable and connected with the
adjoining parts by suitable joints. As applied to closets these improvements are
as follows:-
:-
The lower part of the closet basin is by a metallic or other joint so connected to
the trap that the latter can turn against the former, say, to an angle of about
90 degrees, the trap is for this purpose fitted with a handle. The piece of pipe
connected to the glazed or other drain pipe is also similarly connected to the lower
or exit part of the trap.
The closet and the piece of pipe are mounted on a wrought iron or other bed
plate or frame.
The closet basin, the trap, and the piece of pipe may suitably be made of
enamelled cast iron. One or more set screws are used to hold them together.

page_text: The joints may be gun metal or zinc rings with conical or part spherical joint
faces.
To clean out the trap turn it backwards and forwards about a quarter of a turn,
adding water if required through the closet pan.
The trap is in a similar manner connected to other abduction pipes or apparatus 5
in connection with drains.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Carl Kesseler in the Great Seal Patent Office on the 30th September
1879.

CARL KESSELER, of 63, Mohrenstrasse, Berlin, W., in the Empire of Germany,
Civil Engineer and Patent Solicitor. "IMPROVEMENTS IN CLOSETS AND IN SYPHON
TRAPS FOR SAME, AND FOR OTHER APPARATUS IN CONNECTION WITH SOIL PIPES
AND DRAINS." (A communication from Robert Westphal, of Greifswald, Germany,
Architect.)
Syphon traps have heretofore been held to be the best means for preventing
noxious or unpleasant gases from rising out of vertical or inclined soil or drain
pipes for the abduction of impure fluids or substances. In practice, however, it is
found that such traps become stopped up easily, and the object of this Invention is
mainly to do away with this evil.
For this purpose the syphon trap is made movable and connected with the
adjoining parts by suitable joints.
And in order that this Invention may be more fully understood I will describe,
as an example, its application to a water closet, with reference to the accompanying
Drawings, Figure 1 being a vertical section through such a closet. I wish it
however to be understood that the Invention is applicable to all syphon traps where
a stoppage of same may be feared.
The lower part of the closet basin or hopper A is by a metallic or other joint so
connected to the trap B that the latter can turn against the former, say, to an angle
of about 90 degrees, the trap is for this purpose fitted with a handle f. Figure 2
shews the joint to a larger scale. The piece of pipe C connected to the glazed or
other drain pipe D is also similarly by a joint connected to the lower or exit part
of the trap, as shewn. The closet and the piece of pipe are mounted on a wrought
iron or other bed plate or frame E. The closet basin or hopper A, the trap B, and
the piece of pipe C may suitably be made of enamelled cast iron; one or more set
screws e are used to hold them together.
Figures 3 to 6 represent sections on lines a, b, c, d, e, f, and g, h.
The joints may be gun metal or zinc ring, as shewn, with conical or part spherical
joint faces slightly ground together; there is thus no fear of rusting together.
By making the plate E of wrought iron or of such dimensions as to feather to a

page_text: certain extent, the joint pressure is rendered elastic, the plate bending to a very
small extent, and the consequent slight displacement of the joint parts against one
another do not affect the tightness of the joints as the conical faces of same may be
considered spherical with radius struck from the centre O.
To clean out the trap turn it backwards and forwards about a quarter of a turn,
moving the lever finto the horizontal position and then back again, adding water
if required through the closet pan.
The trap is in a similar manner connected to other abduction pipes or apparatus
in connection with drains.
And having thus described and ascertained the nature of this Invention I declare
that I claim,-
First. The combination of a movable fluid joint with a closet or water outlet of
any sort closed by syphon trap, substantially as and for the purpose set forth.
Second. A syphon trap movably connected with the inlet and outlet parts so
as to turn between the same, and with joints formed by metallic joints, rings,
stuffing boxes, india rubber joints, rings, or other suitable joints, substantially as
and for the purpose set forth.
In witness whereof, I, the said Carl Kesseler, have bereuuto set my hand
and seal, this Twenty-seventh day of September, in the year of our Lord
One thousand eight hundred and seventy nine.
