COMPLETE SPECIFICATION.
Improvements in a Closet with Automatic and Direct Separation of
the Fluid and Solid Excrements.
I, AUGUST KERSTEN of No 10 Lohzenstrasse Hannover, Germany Architect do
hereby doclare 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 present invention has for its object to improve the closet with automatic and
direct separation of the fluid and solid excrements invented by and patented to me by
the patent No. 13162, Dec. 12th 1888 so that the cover and the sitting board can be
lifted easier and that the quantity of drying material used shall be given out in
definite quantities, one portion of it after the use of the closet. A further improve-
ment which I have made has for its object to simplify the cover and to reduce the
costs of its construction
The improved closet is shown on the accompanying drawing in which
Fig. 1 is a vertical section of the closet, the cover opened and the sitting board
lowered, ready for use.
Fig 2 is a vertical section, the cover closed and the sitting board raised up.
Fig. 3 is a vertical view partly in section, seen at right angle to figs. 1 & 2.
Fig. 4 is a top view.
Fig 5 is a vertical section of the simplified construction showing the cover
raised.
Fig. 6 is a vertical section of the same, the cover closed.
Fig. 7 is a view at right angle to fig. 6 partly in section.
In order to be able to raise the cover and the sitting board easier than heretofore
I now use in place of the levers formerly arranged for this purpose the chain wheel a
on the shafte and a similar wheel b above it, the shaft of which forms the 'turning
axle of the sitting board c, a chain d land round the chain wheels a &b causing the
sitting board to be raised or lowered according to the direction in which it is 'turned.
The turning of the shaft e and the chain wheels accordingly is effected as follows:
Upon the shaft e is mounted a little spur wheel being in gear with the rack
g
forming one piece with or being fixed to the lever h This lever has its fulcrum at i,
it projects beyond the front board k to form a treadle and thus it follows that in
pressing this treadle down from the position shown by fig. 2 into that shown by fig 1,
the rack 9 will be raised and will turn the pinion and the chain wheels in the
direction shown and the cover and sitting board will be lowered.
The lever his prolonged towards the rear of the rack and carries at its end the
weight m having for its object to raise the treadle and the parts connected
therewith when the pressure upon it is released, same as in the old arrangement.
In order to regulate automatically the quantity of drying material used and to
cause a certain amount to be poured upon the excrements afterwards, I have made the
following improvements.
From the reservoir n, containing the drying material, the pipes o and o¹ lead into
the boxes p and p¹ inside of which are fixed the open tubes and so that they can
wing to and fro and that according to their position they form either the continuation
of the pipes o or o¹ respectively or that a plates fixed at their top side shuts up the
communication between them or else closes the bottom of the pipes o and o¹. The
boxes p.and pl are so shaped and the movement of the tubes and within them is
o arranged that when the sitting board is raised the pipe o communicates with the

page_text: tube T, whereas the bottom of the latter is closed by part of the bottom side of the box
and that the communication between pipe o' and tube at the same time is closed by
the plate s¹, whereas the bottom of lineets the lower tube t' which leads into the
pipe D of the closet below the cup F. Thus in this position the tuber is filled with
drying material coming from the reservoir n and that quantity that was contained in
the tube is poured out into the closet.
When then the cover and the sitting board are lowered (fig. 1) the tubes &
change their positions, the plates at the top of tuber shuts the bottom of the pipe o
and the bottom of communicates with the tube t below it leading into the part A of
the closet above the cup F and pouring its contents upon or into the cup F, whereas
pipe now communicates with its feeding pipe o¹, taking up a new portion of
material, the communication with t¹ now being closed.
The movement of the pipes and r¹ is caused as follows I fix a short lever n to
the shaft e being connected by a bar to the arm w which is mounted on the pin
round which the piper swings. A similar arrangement u¹, v¹, to' causes the proper
movement of the pipe r¹.
The stay or rod in front of the board k is arranged in order to avoid the necessity
of pressing continually upon the treadle when using the closet which would be
impossible or very troublesome for small persons or children
The arrangement shown by figs. 5, 6 & 7 differs from the preceding one and from
that patented to me by patent No. 1316288 by the simpler construction of moving
the sitting board and of arranging the cover.
The blind like cover is dispensed with altogether and in its place an ordinary
cover 1 fitting into the hole in the sitting board is used. This cover can be raised by
hand or by means of the treadle arrangement described before.
A lever 2 being fixed on shaft e and being connected to the front edge of the cover
by means of a cord 5 and pulleys 3, 4 by means of which the cover will be raised or
lowered according to the position given to the treadle as will be seen from
figs. 5, 6 & 7. When raised, the cover bears against a spring 6 of the standard 7
which presses it back as soon as the pressure of the treadle or the pull of the cord 5
is released.
The rod 8 pushes the sitting board a little upwards and a bar 10 let into a grove
in the front board 11 causes a perfect closure of the same.
I further arrange the perforated plate 12 so that, if the cover 1 be opened and solid
matter poured into the closet without the cup F and its connections having been
turned upwards by the treadle such matter is caught up by the plate 12 and
prevented from falling into the pipe C, but is thrown into the pipe D by the next
turning of the cup F or the plate 12 respectively.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim 18:
1) The arrangement for lowering and raising the cover and the sitting board of
the closet consisting of the treadle lever 1, the weighted lever in combination with
the rack and pinion g and f, the shaft e and the chain gear a b d
2) The arrangement for measuring the quantity of drying material used, in
separate boxes and for pouring it at separate times from the one into the cup F and
from the other below F into the pipe D and consisting of the rocking pipes r.
placed inside of the boxes p,p¹ respectively and being provided with the plates s, s¹,
the pipes, communicating alternately with the pipes o and o' at their top and with
the pipes and t¹ at their bottom according to the position given them by the
levers u, v, w and the treadle / acting indirectly upon shaft e.
3) The rod supporting the sitting board in combination with the treadle / and
lever for preventing the weight m to raise the sitting board when the treadle is not
loaded by direct pressure.

page_text: 4) The arrangement for raising and lowering the cover 1 (instead of the blind
cover formerly used) by the lever 2 on the shatt e and the cord and pulleys 3, 4, 5
and in combination with the cover 1 the plate 12 opposite to the cup F on shaft e.
Dated this 6th day of May 1889.
