I, MAXIMILIAN ALPHONS THEODOR WIEDE, of Hemelingen, near Bremen,
in the Empire of Germany, Factory Manager, do hereby declare the nature of this
invention to be as follows:
--
My invention relates to earth-closets and it consists chiefly in the employment,
for the discharge of the disinfecting material to be strewn, of a tray connected with
the holder of such material and with the lid of the closet in such a manner that
when the lid is open it will not allow the material to escape, but releases it when
the lid is closed, the material to be strewn being at the same time loosened by a
stirring mechanism.
Upon the seat of the closet I arrange a chest which serves as the back of the
closet and contains the material to be strewn.
The floor of this chest is partially formed by the said tray which is mounted
that
upon a pivot and is connected by rods, with the lid of the closet in such a way,
when the lid is closed, the tray is tilted downwards, whilst when the lid is open it
moves to its highest position.
The fore end of the tray, to which the rods are attached, is formed by a flap or
valve provided with side plates and which when the lid is opened, takes up such a
position that it prevents the exit of the material to be strewn from the tray, but
frees it when the lid is closed. Thus, when the lid is closed, the material can fall
out of the receiver into the pan.
In order that a prescribed amount of material may be made use of at each time
of action a sliding valve is connected with the closet lid by a connecting rod, which
valve when the lid is opened does not extend into the outlet but, when the lid is
closed and the tray drops, enters the outlet and only releases that portion of the
material to be strewn which is then in front of the valve. This valve at the same
time prevents damp vapours from entering the chest.
The mechanism for preventing the material to be strewn from agglomerating or
for loosening it, consists of two or more rods placed in the chest and provided with
arms or cross pieces or other projections, and caused to move upward, downward,
and laterally, when the lid is opened and closed the arms thereby cutting through
and loosening the material to be strewn.
To the valve which regulates the supply of the material out of the chest, and is
raised and lowered by the opening and shutting of the lid, is connected a rod,
sliding in a guide. This rod has at its upper end an eye in which one end of two
pivoted rods engages the other ends of the said rods are connected to two other
rods provided with pins after the manner of a ladder. These rods are bent inwards
at their lower ends, where the latter extend into the chest which tapers towards its
lower end, and are guided in two eyes. When the lid is opened, the rod of the
sliding valve is moved upwards and imparts to the rods carrying the arms a down-
ward and lateral motion whereby the material to be strewn is very effectively
loosened, first when the lid is opened, and again when it is closed, so that
agglomeration is avoided. Instead of the two rods with arms hereinbefore
described several may of course be made use of, or the rod of the sliding valve
inay be furnished with arms.

I, MAXIMILIAN ALPHONS THEODOR WIEDE, of Hemelingen, near Bremen,
in the Empire of Germany, Factory Manager, 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:-
My invention relates to earth-closets and it consists chiefly in the employment,
for the discharge and regulation of the quantity of the disinfecting material to be
strewn, of a tray and valve connected with the holder of such material and with
the lid of the closet in such a manner that when the lid is open the material
cannot escape into the pan, but when the lid is closed a measured quantity will be
discharged, the entrance of damp vapours into the holder being prevented, the
material to be strewn being at the same time loosened by a stirring mechanism.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing, in which :-
Figure 1 is a vertical section of an earth-closet constructed according to my
invention the lid being shewn closed.
Figure 2 is a sectional side elevation of the closet with the lid open.
Figure 3 is a rear elevation of Figure 1 with the back removed; and,
Figure 4 is a front elevation of Figure 1.
Upon the seat of the closet I arrange a chest A which serves as the back of the
closet and contains the material to be strewn.
The floor of this chest is partially formed by the tray & wbich is mounted upon
a pivot and is connected by rods with the lid m of the closet in such a way, that
when the lid is closed, the tray is tilted downwards, as shewn in Figure 1, whilst
when the lid is open it moves to its highest position as shewn in Figure 2.
The fore end of the tray, to which the rods are attached, is formed by a flap
or valve o pivotted at n and provided with side plates. The flap or valve o, when
the lid is opened, takes up such a position that it prevents the exit of the material
to be strewn from the tray, but frees it when the lid is closed. Thus, when the
lid is closed, the material can fall out of the receiver into the pan.
In order that a prescribed amount of material may be made use of at each time
of action a sliding valve a is connected with the closet lid m by a connecting rod
or link P which valve when the lid is opened does not extend into the outlet but,
when the lid is closed and the tray drops, enters the outlet and only releases that
portion of the material to be strewn which is then in front of the valve. This
valve at the same time prevents damp vapours from entering the chest A.
The mechanism for preventing the material to be strewn from agglomerating, or
for loosening it, consists of two or more rods placed in the chest and provided with
arms or cross pieces or other projections, and caused to move upward, downward,
and laterally, when the lid is opened and closed the arms thereby cutting through
and loosening the material to be strewn.
To the valve a which regulates the supply of the material out of the chest A
and is raised and lowered by the opening and shutting of the lid, is connected a
rod c, sliding in a guide . This rod c has at its upper end an eye in which engages
one end of each of two arms e, e' pivotted at d, d'; the other ends of the said rods
are connected to two other rods y, g' provided with pins f after the manner of a
ladder. These rods g, g' are bent inwards at their lower ends, to correspond with
the tapering of the chest A, and are guided in two eyes h, h. When the lid of the
closet is closed the rods 9, 91 take the position shewn by the full lines in Figure 3.
If the lid be opened the rod c of the sliding valve will be moved upwards and
impart to the rods jointed to the arms e, e' a downward and lateral motion moving
them into the position shewn in dotted lines in Figure 3. By means of these rod.

page_text: and their pins the material to be strewn will be very effectively loosened, first
when the lid is opened, and again when it is closed, so that agglomeration is
avoided. Instead of the two rods with arms hereinbefore described several may
of course be made use of, or the rod c of the sliding valve may be furnished
with arms.
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 is :-
1. An earth-closet in which the discharge of the disinfecting material to be
strewn is effected by means of a tray connected with the holder of such material
and with the lid of the closet in such a manner that when the lid is open the said
tray will not allow the material to escape but releases it when the lid is closed, the
material to be strewn being at the same time loosened by a stirring mechanism,
substantially as herein before described.
2. In an earth-closet of the kind claimed in the preceding claiming clause a flap
or valve forming the fore-end of the tray and pivotted thereto and so connected to
the lid of the closet as to allow the contents of the tray to issue from it or to
retain them according to the position of the lid, substantially as hereinbefore
described.
3. In an earth-closet of the kind claimed in Claim 1, a sliding valve connected
with the closet-lid, by a connecting-rod or link or the like, which valve enters the
outlet for the material to be strewn and according to the position of the lid opens
or closes the said outlet, and divides the portion of the material to be strewn
which lies in front of it from the main supply, and at the same time prevents damp
vapours from entering the holder, substantially as hereinbefore described.
4. In an earth-closet of the kind claimed in Claim 1, the mechanism for stirring
the material to be strewn, consisting of two rods g, g¹ or a larger number of such
rods, suitably provided with arms or other projections, and passing through the
holder, to which rods an up and down and lateral movement is imparted by the
opening and shutting of the lid, whereby the material to be strewn is loosened,
substantially as set forth.
5. The improved earth-closet hereinbefore described and illustrated in the
accompanying drawing.
