PROVISIONAL SPECIFICATION.
Improvements in Water Closets.
I, JOHN SHANKS, Junior, of Tubal Works, Barrhead, in the County of
Renfrew, North Britain, Sanitary Engineer, do hereby declare the nature of this
invention to be as follows, that is to say :-
My said invention has for its object to provide an improvel, compact, simple,
efficient, and economical water closet, which I construct preferably of the detached
pedestal type, although my invention is also partly applicable to other types.
In a water closet made according to my invention the basin is of an approximately
conical form, the back being inclined downwards and forwards from the inlet for
the flushing water, the basin discharge outlet being at the bottom and communicating
with a trap bend or siphonal bend extending up the back to the necessary height
and terminating in a nozzle or flange or enlarged neck to be connected to the
waste pipe. The basin is made with a hollow rim at the top or is provided with a
fan to distribute part of the flushing water all round the basin; a large portion,
however of the flushing water is directed by a nozzle towards the discharge outlet.
at the bottom in order to start and give force to the siphonal action. The back of
the basin being inclined as described, the jet from the nozzle is also inclined and
is parallel or nearly so to the back; and its action is rendered effective by shaping
the part of the passage between the discharge orifice and the ascending leg of the
siphon or trap, with a distinct forward inclination in continuation with the line of
the jet.
The rim or flange at the top of the basin is made comparatively broad at the
back and two or more holes are formed in it, for directly fixing to it a bar or piece
of wood to which the closet seat may be hinged. The water supply cistern may
be close to the water closet at the back or at any convenient height above.

Improvements in Water Closets.
I, JOHN SHANKS, Junior, of Tubal Works, Barrhead, in the County of Renfrew,
North Britain, Sanitary Engineer, 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, that is to say :-
My said invention has for its object to provide an improved, compact, simple,
efficient, and economical water closet, which I construct preferably of the detached
pedestal type, although my invention is also partly applicable to other types.
In a water closet made according to my invention the basin is of an approximately
conical form, the back being inclined downwards and forwards from the inlet for
the flushing water, the basin discharge outlet being at the bottom and communicating
with a trap or siphonal bend. The basin is made with a hollow rim at the top or
is provided with a fan to distribute part of the flushing water all round. the basin;
T

page_text: a large portion however of the flushing water is directed by a nozzle towards the
discharge outlet at the bottom in order to start and give force to the siphonal
action. The passage between the discharge orifice and the ascending leg of the
siphon or trap is specially shaped and the top of the closet basin made in a
particular manner hereinafter described.
And in order that my said invention and the manner of performing the same
may be properly understood 1 hereunto append a sheet of explanatory drawings to
be hereinafter referred to and showing three modifications of water closets as mado
according to my invention.
Figures, 1, 2, and 3, of the drawings are vertical sections respectively of the
three modifications.
Figures, 4, and 5, are plans respectively of the modifications shown in Figures, 1,
and 2.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
In a water closet made according to either of the three modifications the
basin, A, is of an approximately conical form, the back, B, being inclined down-
wards and forwards from the inlet, C, for the flushing water, the basin discharge
outlet, D, being at the bottom and communicating with a trap bend or siphonal
bend, E, extending up the back to the necessary height and terminating in a nozzle
(Figure, 1) or flange (Figure, 2) or enlarged neck, G (Figure, 3) to be connected
to the soil pipe, H. The basin, A, is made with a hollow rim, J, at the top or is
provided with a fan to distribute part of the flushing water all round the basin; a
large portion however of the flushing water is directed by a nozzle, K, towards
the discharge outlet, D, at the bottom in order to start and give force to the.
siphonal action. The back, B, of the basin, A, being inclined as described, the
jet from the nozzle, K, is also inclined and is parallel or nearly so to the back;
and its action is rendered effective by shaping the part of the passage between the
discharge orifice, D, and the ascending leg of the siphon or trap, E, with a distinct
forward inclination in continuation with the line of the jet.
The rim or flange, J, at the top of the basin, A., is made comparatively broad
at the back, L, and two or more holes, M, are formed in it for directly fixing to it
a bar or piece of wood to which the closet seat may be hinged. The water supply
cistern may be close to the water closet at the back or at any convenient place."
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. Making a water closet basin, and especially the back part and the entrance to
the sipbon discharge outlet, of the form shown in vertical sention in the
accompanying drawings and with a nozzle for directing a large part of the flushing
water into the said discharge outlet substantially as and for the purposes herein-
before described,
2. Making a water closet basin with a top rim which is comparatively broad at
the back and has two or more holes for fixing thereto a bar to which the closet
seat may be hinged substantially as hereinbefore described.
