Improvements relating to Privies and Close-stools.
We, ANDERS MAGNUS PETERSSON, of Limhamn, in the County of Skåne, Sweden,
Engineer, and HANS PETERSSON, of Malmö, in the County of Skåne, Sweden,
Instrument Maker, do hereby declare the nature of this invention to be as
follows:-
Our invention has for its object to automatically disinfect excrement vessels or
receptacles by means of bog-earth and consists in arranging under a receptacle
containing bog-earth adapted as a back to the close-stool a blocking up valve or a
kind of bottom, constituting about the quarter of a hollow cylinder. This valve is
located along the back part of the close-stool having the convex surface turned
downwards and resting upon a support formed for this surface and pivoted to the
geometrical axis of the cylinder, this valve being moreover at its front part movably
connected with a shovel, which in the motion of the valve changes its position, so as
either to retain the earth in the valve or to deliver part of it into the excrement
vessel. The valve is by means of levers connected either with the seat, which in this
case ought to be movable, or with the close-stool-lid so that when depressing the
seat or lifting the lid the valve is pushed backwards thus drawing the shovel under
the earth receptacle, the contents of which will thereby drop down into the said
shovel. In lifting the seat or letting down the lid, the valve with the shovel
advances again, which latter is then tilted over and its contents discharged into the
excrement vessel. In order to facilitate the movements of the valve there may be
arranged under the same a pair of rollers, on which the said valve slides.
Our said invention also relates to an arrangement for preventing the earth
contained in the receptacle from clogging together. This arrangement consists of a
frame located in the earth receptacle and provided with pins and connected with the
mechanism for effecting the motion of the above mentioned valve, so that the frame
moves up and down in the motion of the valve, whereby the pins are caused to stir
the earth contained in the receptacle thus preventing the clogging of the same
together.

Improvements relating to Privies and Close-stools.
WO, ANDERS MAGNUS PETERSSON, of Limhamn, in the County of Skåne, Engineer,
and HANS PETERSSON, of Malmö in the County of Skåne, Instrument Maker, both in
the Kingdom of Sweden, 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 an arrangement for automatically disinfecting closet-
vessels by means of bog-earth and consists in the use of a stop valve having the
shape of a quarter section of a hollow cylinder secured under the bog-earth receptacle
constituting the back of the closet-stool, which receptacle is somewhat contracted
behind and at the sides by means of inserted plates. The stop valve is located along
the back of the closet-stool with the convex surface downwards and slides upon a
r D 027

page_text: support formed with a corresponding surface the said valve being pivoted on the
geometrical axis of the cylinder at about of the circumference and is attached in
front by means of a hinge-joint to a plate shovel, which in consequence of the motion
of the valves changes its position so as either to retain the earth in the valve or to
deliver part of the same into the closet-vessel. In the earth receptacle a shaking
device may be arranged in order to prevent the bog-earth from clogging.
In the accompanying drawing,
Figures 1 and 2 represent a cross section of such a closet-stool in two different
positions without the shaking apparatus.
Figure 3 is a plan.
Figures 4 and 5 show a modification of the closet-stool in two different positions.
Figures 6 and 7 represent a closet-stool with the shaking apparatus in sectional
elevation and a cross section with the back taken away.
A is the valve to which the shovel B is fixed by means of hinges. When using
the closet-stool, the valve A slides up between the back of the receptacle and the
plate fixed therein thus leaving an opening for the bog-earth to drop down upon
the shovel B (Figure 2) which is at this time drawn in by the valve under the
bog-earth receptacle. When the valve is pushed forward the shovel B advances and
when it has advanced sufficiently beyond the support D it will turn down by its
own weight into such a position as to cause the earth to be turned over into the
closet vessel as shown Figure 1.
The motion is imparted to the valve either by means of a movable seat on the
closet-stool Figures 1, 2 or by means of the motion of the closet-lid (Figures 4 and 5).
In the first case the motion is obtained by two double-armed levers E fixed at the
inner sides of the closet-stool close under the seat, one lever at each side, which
levers are by means of springs H maintained in such a position as to raise the seat
in front (Figure 1). These levers are united behind, by means of links T with two
levers K of the second order pivoted at one end behind the plate at the sides of the
bog-earth receptacle, and at the other ends united by means of pivots with the
valve A. In the latter case, where the motion of the valve is effected by the movement
of the closet lid, the above double armed levers E are replaced by arms L projecting
backwards from the under-side of the lid and being slightly bent upwards. The
aforesaid levers of the second order fixed to the valve are here discarded in favour
of bent levers N fixed at the same points in the earth receptacle as the levers K
that is in the centre of the valve. The bent levers N and the arms L projecting
from the lid are united by means of links O.
The arrangement which is provided in order to prevent the earth from clogging
in the receptacle consists of a frame G₁ supported by two side bars F1 and provided
with pins H by which the earth is stirred. In order that the shaking may take
place at the same time as the other mechanism is operated, the two bars F supporting
the frame G are fixed by their lower ends to the above mentioned bars K which
serve to open the bottom mouth of the bog earth receptacle. The bars F are fixed
by means of pivots to each end of the top cross bar of the frame G. The frame G¹
has likewise a support at the front wall of the bog-earth receptacle. The levers K
when moving upward when the closet-stool is used impart their motion to the
bars F which will in their turn raise the frame G. When the mechanism returns
that is, when the levers K are lowered, the frame will evidently recoive a downward
motion. During this alternate motion the bog-earth will be stirred by the pins H¹
fixed to the frame.
In order to facilitate the motion of the valve A certain rollers M are provided
running in bearings fixed in a cross bar 0¹ extending between the two side walls
of the closet-stool or any suitable way. In lieu of springs pressing upon the levers E
to maintain the seat in a raised position, a counterbalanced weight may be applied
to the back of the valve which when the seat is unoccupied depresses the hind ends
of the levers E, so that the fore ends of these maintain the seat in a raised
position.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
First. The arrangement for automatically disinfecting closet-stools and privy-
houses consisting of a bog-earth receptacle provided with a valvo or bottom (A, B,)
composed of two parts united by means of hinges, of which one (A) swings on
central pivots, when the lid or the seat is moved, and the other (B) carried by a
support (D) over which the flap B turns when the former position has been moved
forward and the hinges uniting the both parts are near the said support.
Second. In combination with the arrangement above described, of an arrangement
for preventing the bog earth from clogging, consisting in the employment of a bog
carth receptacle having a frame (G') supported by two bars, fixed in levers (K, N)
by means of which the valve (A) of the earth receptacle is turned, in order that the
frame may be moved, when the other mechanism is put in motion.
Third. In combination with the arrangement above described of an arrangement
for rendering the valve more easy to move, consisting of rollers (M) arranged
under the said valve and on which rollers the said valve is adapted to slide.
