COMPLETE SPECIFICATION (AMENDED).
An Improvement in Water Closets or Water Closet Basins..
I, WILLIAM THOMAS ALLEN, of Uppington House, Tamworth Road, Gravelly Hill,
near the City of Birmingham, Builder, do hereby declare the nature of this inven-
tion 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 a detail improvement in adjustable and other water closets,
or to the basins or pans of the same, and relates primarily to that class in which
surface or waste water is utilized for the efficient cleansing of the same, and which
said invention is an improvement upon two several Letters Patent granted to me and
bearing date the 6th day of November 1890 No. 17823 and the 25th day of August
1891 No. 14334, and has for its object, the flushing of the basin without the em-
ployment of revolvers or overbalancing tips, and this I accomplish by so constructing.
the inlet passage to the basin that the surface water is made to take a head and run
directly into the said basin in such a manner that efficient flushing is performed.
Thus, the basin or other part of the closet is furnished with a curved arm, whose
inlet is at a considerably higher level that its outlet, or the inlet to the pan, and by
arranging such a drop in the passage, a precipitous rush or head of water is acquired
thereby, and the same is made to drop directly upon the top of the soil, which is
removed through the trap connected with the neck of the basin, which may be of a
coned or other shape as desired.
By utilizing the surface drainage by connecting the pan directly to the gully as
described, chambers for containing tippers or revolvers are dispensed with, and the
cost of ensuring perfect sanitation is considerably lessened.
Figure 1 of the accompanying drawing represents, in longitudinal vertical
section, a water closet fitted with gully, surface drainage arrangements, pipes and
trap, and having a basin provided with an improvement or improvements made
according to my invention.
Figure 2 represents a back end view of the said basin separately.
The same letters of reference indicate corresponding parts in the several figures of
the drawing.
a is an inverted cone-shaped basin with top socket a², neck a³, and an inlet arm b,
constructed, made or arranged according to one form of my invention. The said
arm b, consists of a truncated shaped drop pipe, having an entrance 61, a nearly
vertical drop passage 62 and an outlet 63, preferably slightly choked, leading to the
basin, and with a shoot incline 64, for directing the head of water to the top of the
soil, which is thereby forced through the S or other syphon trap c, with the flange c²,
of which, the neck a³, of the pan takes and seats itself. This said S or other syphon
trap has its outlet c³ fitted to the main-drainage d, by the said end taking into the

page_text: socket d¹. Fitting into the top a², of the pan a, is an intermediate drum-shaped
section e, forming part of the walls of the structure, whilst fitting within the socket e²,
at the top of it, is a closet top-pipe f, having a hopper shaped basin f, inlet slit or
opening, at bottom, and ventilating annular air space f, in communication
with an air shaft or pipe f. Fitted to the top of the water closet or pipe is a
seat g.
In the surface drainage part, h is the gulley of a syphon or other trap construction,
and i,j, are drainage pipes, arranged to have a proper drop for the efficient running
of water into the flushing arm b.
My invention is particularly applicable to deep water closets, or water closets
having the traps disposed immediately under and at a considerable distance below
the seat or hopper pan.
I wish it to be also understood that my invention is applicable to closets without
the upper part head f, constructed as described, that is, the said upper part may be
constructed alike unto the middle part, which may be provided with a seat, and-still
further, where-a greater head-of-water-is--required, and--where the-drop-of-the
drainage-will-permit,-the-intermediate-pipe-e, may be fitted with the-arm-6,-instead
of-the-same-being fitted-with-the-pan-a, or I may extend the lower or foot-part-of
the-pipe-f-downwards to-an-extent-more-or-less-equal to the depth of the middle
pipe e, and which extended part may-have-an-arm-alike unto-b.
Instead of the arm b being made in one piece with the basin, pipe or the like as
represented in Figure 1, the same may be made in two sectional parts.
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
First: In water-closets or water closet basins, pans, or pipes, providing the
sume-or-such-structural parts of the same with a-water shoot-arm, segmentally or
integrally made, and having a vertical or nearly vertical drop terminated at the
busin-or-pipe by an incline or shoot, substantially-as-and for the purpose as-de-
seribod-and-set-forth.
Secondly Inf water closets,-or-water-closet basins, pans or-pipes with-arms-or
pipe--entrances, constructed, arranged and provided substantially as and for the
purpose as described and set forth.
Dated this 27th day of November 1893.
