PROVISIONAL SPECIFICATION left by the said Gerard Wenzeslaus von
Nawrocki at the Office of the Commissioners of Patents on the 17th January
1883.
GERARD WENZESLAUS VON NAWROCKI, Proprietor of the firm of J. Brandt
& G. W. v. Nawrocki, Patent Solicitor and Civil-Engineer, of 124 Leipzigerstrasse,
Berlin, Germany, "IMPROVEMENTS IN APPARATUS FOR THE TREATMENT OF FECAL
MATTERS a communication to me by Julius Swiecianowski, a person resident at
Warsaw, in the Russian Empire.
This invention has for its object to separate the liquid from the solid or semi-
solid parts and to dry the latter at or near their place of production.
For this purpose the apparatus consists of three principal parts, namely the
collector preferably situated under the vertical tube through which the fecal
matters fall, a filter for the liquid: parts and a furnace for drying the solid or
semi-solid parts.
The collector is composed of two concentrical vessels, the inner one of which is
perforated to allow the liquid to pass into the annular space formed between the
two vessels, while the solid portion remains behind. and is periodically discharged
into the furnace through a vertical tube provided with a lid or valve.
The filtering apparatus which receives the liquid from the collector contains
several superposed filters containing powdered peat or other suitable material, and
serving to abstract ammonia and salts from the urine. The furnace is separated
into two parts by a horizontal partition, the upper part containing a series of
exchangeable pans, while the lower part contains the fire-place and the flues and is
traversed by an inclined pipe communicating with the filtering apparatus and with
the upper part of the furnace.
The upper part has a cover and communicates with the fire-place by a pipe.
A series of horizontal or inclined pipes which pass through the lower part (flues)
of the furnace admit atmospheric air at one end and deliver it heated into the
upper part of the furnace.

Office on the 16th July 1883.

and G. W. v. Nawrocki, Patent Solicitor and Civil Engineer, of 124 Leipzigerstrasse,
Berlin, Germany, "IMPROVEMENTS IN APPARATUS FOR THE TREATMENT OF FECAL
MATTERS." A communication to me by Julius Swiecianowski, a person resident at
Warsaw, in the Russian Empire
This invention has for its object to separate the liquid from the solid or semi
solid parts and to dry the latter at or near their place of production.
The accompanying drawing shows an apparatus embodying the invention,
Fig. 1 being a vertical section, Fig. 2 an elevation, Fig. 3 a top view and Fig. 4
a horizontal section.
The apparatus comprises a collector A, a filter B and a furnace C.
The collector is composed of two concentric vessels, the inner one of which is
perforated to allow the liquid to pass into the annular space b formed between
the two vessels, while the solid portion remains and is periodically discharged into
the furnace through a vertical tube d provided with a lid or valve.
The liquid is conducted through the pipe i into the hermetically closed filtering
vessel B and passes successively through its several superposed filters containing
powdered peat or other suitable material which serves to abstract ammonia and
Balts from the urine, so that the latter escapes through the pipe o in the shape of
pure water.
The solid parts pass through the pipe a into collector A, and are then conducted
into the pans I, II. 11I which can be exchanged and serve to extract the last
particles of liquid contained in the solid parts, thereby drying the latter perfectly.
The furnace is separated into two parts by a horizontal partition. The upper
part receives the matters which have to be dried and is closed by a double
cover. g g'. The lower part contains the fire place and the flues and is traversed
by the pipe h.
The working of this apparatus is as follows:
As soon as a sufficient quantity of fecal matters have accumulated in the
collector A, a fire is lighted in the furnace in order to produce a suitable ventilation;
then the pans I, II, III are filled successively by the pipe d, and the furnace is
closed by means of the cover g.
Consequently a current of air passes in the direction shown by the arrows, 80
that air and gases from the filters are sucked through the pipe h³, while through
the pipe fresh air is admitted over the pans into the drying-chamber, from where
it is led for the purpose of combustion through the pipe underneath the grate,
carrying away the gases and humidity produced by evaporation.
1. An apparatus for drying fecal matters at the place of their production, consisting
of the collector A for separating the solid from the liquid matters, the filter B and
the furnace C, substantially as described.
2.) An evaporating furnace C divided into two compartments by a partition k;
the lower compartment being the fireplace or combustion chamber traversed by a
circulating pipe conducting heated air into the upper part, which contains the

page_text: matters to be dried, while the gases and vapours generated in the upper com-
partment are conducted by the pipe i into the fire place and finally discharged,
substantially as described.
In witness whereof I, the said Gerard Wenzeslaus von Nawrocki have hereunto
set my hand and seal this 11th day of July A.D. 1883.
