1, JOHN WARD JAMESON, of Hexham, in the County of Northumberland, Master
of the Workhouse, do hereby declare the nature of my invention for "IMPROVEMENTS
IN AUTOMATIC EARTH CLOSETS" to be as follows:-
The suspension of the Hopper containing the deodorant is eccentrical. A cross-bar
is fixed above the point where it discharges & on the same side. Two radiating bars
are fixed to the seat of the closet (which moves on a pivot) and when used cause the
radiating bars to press against the cross bar on the hopper & press it away from the
centre to the required distance so that when the seat is liberated the radiating bars fall,
back with the scat & the hopper falls back by gravitation & being suddenly checked
discharges the deodorant in the required quantity to the point desired.
The plan of suspending the Hopper & the radiating bars are the chief, though;
not the only, novelties in this invention & for which this patent is applied for.
The real merit of this closet is its complete efficacy & extreme simplicity.

page_text: 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 comprises improved means for auto-
matically discharging the desired quantity of the deodorant upon the excreta as
hereinafter described.
In the accompanying drawings
Figure 1 is a front elevation of an earth closet constructed according to my
invention.
Figure 2 is a side elevation; and,
Figure 3 is a plan of the same.
Figure 4 is a section on the liner, a Figures 1 and 3.
Figures 5 and 6 are a front elevation and vertical section respectively illustrating a
modification of my invention.
a is the frame of the closet having the uprights a¹ and the cross bar a²; and 6 is
the seat which is supported upon trunnions c, c carried in bearings d, d on the frame a
and provided with the lid b'..
e is the hopper or receptacle for containing the deodorant, the walls of the said
receptacle inclining towards each other at the lower end, and terminating in a shoot
or spout f, through which the deodorant is discharged. The hopper is not pivotted
centrally but at one edge as shown at g Figures 2, 3 and 4 and it is suspended from
the cross bar a² so that its normal tendency is to oscillate or swing towards the back
of the closet.
h, hare two "radiating bars" secured to the underside of the seat and projecting
at one end to form arms i, i which bear against a cross bar j.secured to the front of
the hopper. The arms i, i are shaped for instance as shown in Figures 2 and 4 so
that when the front part of the seat is depressed by the weight of a person thereon
the said arms will in rising-with the back part of the seat exert a cam-like action upon
the bar j and move the hopper e outwards to the position indicated by dotted lines in
Figure 4. When the person rises from the seat the gravity of the hopper and its
contents causes the said hopper to swing back to its normal position where it is
suddenly arrested by striking against stops k; k on the seat whereby a portion of the
deodorant contained in the hopper is, owing to the impetus imparted to it, discharged
through the spout onto the excreta.
In the modification of my invention illustrated. in Figures 5 and 6 the bars h, h and
arms i, i are dispensed with. In this case a cam-shaped projection 7 is secured to the
hopper, against which projection the seat bears, so that when the seat is depressed the
hopper will be moved outwards as herein before described.
I wish it understood that I do not limit my invention to the details of construction
herein before described, as it is obvious that the same may be considerably varied
without departing from the nature of my invention.

page_text: 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 1
claim is
(1) An earth closet or. commode the deodorant receptacle of which is pivotted in
such a
manner that the oscillation of the same serves for the discharge of its
contents, substantially as described.
(2) An earth closet or commode the deodorant receptacle of which is suspended at
one side of its axis and the seat of which is so supported as to act upon the said
receptacle to oscillate the same when the seat is depressed by the weight of a person
sitting thereon so that when the weight is removed from the said seat the receptacle
will swing to its norinal position and thereby discharge some of its contents,
substantially as described.
(3) In an earth closet or commode of the kind herein before described the arrange-
ment of arms adapted to act upon the deodorant receptacle to oscillate the same,
substantially as set forth with reference to Figures 1 to 4 of the accompanying
drawings.
(4) The modification of my invention wherein the seat acts upon a cam substantially
in the manner described with reference to Figures 5 and 6 of the accompanying
drawings.
(5) The manufacture and use of earth closets or commodes arranged substantially as
hereinbefore described and illustrated in the accompanying drawings.
