Improvements in and Connected with Water-closets.
I, JOHN DEAN, of Market Place, Middleton, in the County of Lancashire, Plumber,
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 improvements in that class of water closets in which the
supply of water used for flushing the basin is effected or controlled by the action of
a hinged seat, and in which an after-flush of disinfectant takes place, the object of my
improvements being to simplify and make the means for Hushing and disinfecting
more reliable, readily applicable and automatic in their action, than heretofore has
been the case.
And in order that my invention may be more fully understood I have caused to be
appended hereunto two sheets of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. is a cross section and Fig. 2 a front view of a hinged closet seat in
connection with an ordinary syphon cistern, of one form of my invention.
Figs. 3 & 5 are front views, and Figs. 4 & 6, plans, of means for securing the
seat bracket to the back of the closet.
Fig. 7. is a vertical cross section of the seat of another form of my invention.
Fig. 8 is a cross section of the seat showing a modifications of my invention, and 9,
a cross section of a cistern formed with means for disinfecting.

In carrying out my invention and referring to Figs. 1. & 2 the improvements
consist in the first place, in the employment of a contact piece a arranged either
stationary or movable, directly or indirectly under the influence of a weight or an air
or liquid cushion c, or both, which contact piece a, by suitable connections with the
siphon cistern valve lever é and hinged seat d, on the latter being used, causes the
siphon cistern valve lever e to be operated and the flushing to take place.
e
When employing the contact piece a moveable, see Figs. 1 & 2, the same is formed
on a lever g arranged to rock on a stud y fixed to a bracket i supporting the closet
seat.
The front end of the lever is furnished with an anti-friction bowl, against
which the respective end of the hinged seat d bears, and the back end with a weight b
in conjunction with a cylinder h', having a plunger or piston 2, 3 working therein,
the rod of which, is pivoted to the lever g between its back end and stud.
In conjunction with the said contact piece a a trigger f is arranged and fixed by
means of the stud f¹ to the bracket i, on the side of the lever g.
The trigger is under the influence of a spring f, and its lower arm furnished
with an anti-friction bowl against which the contact piece a acts, and its upper
arm connected to the chain k, ordinary attached to the siphon cistern valve levere &
actuated by hand through pulling.
The contact piece a is formed with an incline a' and radial part a², the incline a¹
on coming into contact with the bowl of the trigger f, causing the siphon cistern
valve lever e, to be depressed (as when pulling by hand) and the valve to be opened,
while the radial part a serves as a dwell during which time the cistern valve remains
open.
This dwell may be made so as to be adjustable in length in order to close the valve
at any desired moment.
The weight b, serves to raise the hinged seat d to its normal position, by means of
the lever g, the motion of which, is controlled by bringing it under the influence of an
air or liquid cushion c created by means of the cylinder and its plunger or
12 13

page_text: In order to vary the speed at which the lever g shall move, the plunger or piston h², h³,
is formed with two discs h* & capable of rotary adjustment on its rod h*, and each
with an opening 3, which on being brought more or less over each other, permit the
air or liquid to pass from one side of the plunger or piston h2, h3 accordingly quicker
or slower, to the other side thereof.
The contact piece a may be arranged movable in various forms; it may assume the
shape of a segmental lever arranged to rock on a stud and operated from the hinged
seat by means of levers or chains running over pulleys, the contact portion thereof
acting upon a finger or trigger f, similar as described. The means & method of
operating the cistern valve as described, is not only applicable for syphon cisterns but
also to double valve cisterns.
The same object may be attained in syphon cisterns, see Fig. 7, by employing the
contact piece a stationary, instead of movable, underneath and on the side of the
seat d.
The cistern valve lever e is acted upon by the contact piece by means of a link m
connected thereto by means of a chain k, the lower extremity of the link m being
furnished with an anti-friction bowl m'. The said link m is brought under the
influence of a weight m², connected thereto by means of a chain m³, and the action of
the seat d. by means of a nose n fixed underneath the same, bearing against a lever n
suitably pivoted to the seat bracket, i and the chain n' riding over a pulley n³ and
connecting the link m to the lever n¹.
On the closet being used, the sent d depresses the lever n' which causes the link m
to ride over the contact piece a and drop below the front thereof, while on leaving the
seat d, the link m by reason of the weight m², is caused to pass underneath the contact
piece a, during which time the cistern valve remains open and the flushing is effected,
and to return to its normal position, thereby releasing the cistern valve lever e and
raising the seat d.
If deemed necessary the action of the weight m³ may be checked and controlled by
an air or liquid cushion similar as hereinbefore described, pretorably as illustrated
in Fig. 7.
Another method of operating the cistern valve lover e, in single valve cisterns, by a
hinged seat d, see Fig. 8, consists in suitably employing underneath and on the side
of the same, a pair of levres o & o¹ connected to each other, and respectively arranged
to rock on a stud o* and o³.
The free end of the back lever o, by means of the chain k, is connected to the
cistern valve lever e and the free end of the front lever ol furnished with an anti-
friction bowl, on which the hinged seat d bears.
My invention relates in the second place to improved means for facilitating a ready
fixing of the cistern valve and seat motion and consists in the employment of a
removable bracket i carrying the same, see Fig. 1. in conjunction with a fixed socket
or bracket ¹, suitably secured to the back of the closet.
The top near the back of the bracket i is of T or other suitable shape so as to fit
into a corresponding recess and slot and, formed in the bracket, which latter
supports and retains the bracket i in its proper position, the lower end of which is
secured to the back of the closet preferably by means of a screw s.
The invention consists in the third place in hiding the valve and seat action, and
closet basin, from view, by providing the front of the hinged seat d with a cover
board d' suitably secured thereto see Fig. 1.
In order to effect a flush of disinfectant after the ordinary flush in single valve
cistern, see Fig. 9. a double valve p, p', operated by the cistern valve lever e may be
employed in the cistern. These valves p, p' are employed one below the other, each
in a separate chamber y, q¹ and are connected together by means of a slack chain
passing through the seating p² of the upper valve p. The latter is a plain loaded
valve, while the lower one is formed with a perforated cup p³ in communication with
an inlet q, formed in its chamber q¹.
The upper valve chamber 7 serves to contain the disinfectant, which when the
valve p is lifted admits it into the perforated cup p³, of the valve p', where it is

page_text: dissolved by the water which enters the cup through the inlet ², the perforation
therein admitting it into the chamber q', whence it passes into the cistern and there
through the flush pipe l'into the closet pan, on the valve p being lifted, and for
covering the disinfectant chambers I provide the same with a hinged cover h.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In water closets with hinged seats :-
1st. The general arrangement and combination of parts, operated substantially as
and for the purpose specified.
2nd. The employment of a contact piece a arranged either stationary or movable,
directly or indirectly under the influence of a weight, or an air or liquid cushion, or
both which contact piece a by suitable connection with the cistern valve lever e an
