COMPLETE SPECIFICATION.
Improved Wash-out Closet Apparatus.
I, THOMAS SALTER of 2 King's Road St. Leonard's-on-Sea Sussex, 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:-
The object of my invention is to provide a simple and easily put together water
closet flush-out apparatus, which shall have two special advantageous features, and
shall through the agency thereof, form a definate improvement on any existing water
closet apparatuses of this class.
The two particular features alluded to are firstly, the especial applicability of my
improved apparatus for use in combination with an improved syphon cistern which
I have invented and for which I have this day applied for a Patent, and secondly
the construction of the various parts of my improved apparatus, which allows it to
be adapted with great facility to any existing service of drains whether it be required
to place closet outside or inside the building.
In order that my invention may be more readily understood, I append the
accompanying sheet of drawings in which the like parts are indicated by the like
letters of reference throughout.
Fig. I represents a portion of my improved apparatus in vertical section, and
Figure II shews the whole of the same, part in section, and part in elevation.
Fig. III is an enlarged detail of a part of the apparatus; and which 1 shall fully
explain later on.
A is a china-ware basin provided with an inlet scouring lip, and an undercut rim
to prevent splashing; at the bottom of the basin is a circular spigotted outlet. Bis
a semi-circular bend forming a portion of the syphon, having at one end an enlarged
portion or cup B' which is further furnished with a socket or shoulder. The basin A
rests in the cup B¹, and the spigotted projection thereof, fits down into the socket,
formed at the base of the cup B'.
The other extremity of the bend B terminates in a flange whereof Fig. III shews
an enlarged plan; in this said flange, I form slots as shewn at c-c which are cach
formed of the same lengths as the intervening spaces between them. On the
underside of the bend B is formed a support or pedestal B². C represents a similar
bend to B, but having a slotted flange, the same as just described, at each of
its ends.
D is a further bend of the shape shewn in Figure 11, and having both of its
extremities flanged as described above.
E is a trap having a flange with slots therein as described above, at one of its
extremities, and having its other extremity formed in any ordinary manner for
connection with the drain. The trap E is not a complete air tight one, but has an
air space of about half an inch between the level of the water resting in the trap,
and the upper bend thereof.
All of the above bends B, C, D and E, are of equal diameter, and the flanges at
their extremities correspond to one another in every particular. The said parts of
my apparatus are fastened together by means of galvanized bolts, which pass through
the slots c-c, in the flanges and are secured by nuts.
A washer of india-rubber or other suitable material F, is placed between the
flanges at every joint. It will be readily seen that by reason of the elongated
slots c, c, in the flanges of the different bends each or either bend can be attached
to its neighbouring bends at any angle, and thus admitting of the closet being con-
nected with drain pipes, that may be in existance, or that for any other reason it

page_text: may be necessary or desirable to place in an unusual position with respect to the
closet basin.
When my improved closet apparatus is in operation, the flush water on being
admitted through the scouring lip rushes round the basin thoroughly clearing out
the same, and passes down to the drain through the different bends, described in the
foregoing.
On reaching the trap or bend E, the velocity of the flow of water from the basin
is partially checked or impeded, and this prevents a vacuum being formed in the
bends by reason of such velocity, were it allowed to continue down the drain, and
which would tend to draw away the after flush water which is passed from the
cistern to the basin after the flush out has been mainly effected. At the same
time the bend E must not form a complete air tight trap or a similar exhaustion of
..the after flush water will be brought about, and it is for this reason that an air
space is left in the said trap E, as mentioned in a previous paragraph.
The real trap in connection with my improved apparatus takes place in the
syphon formed by the bends B and C, in which the after-flush water rests to the
level shewn by dotted lines in Figure 1; and it is thus apparent that my improved
closet apparatus can only be used in conjunction with an efficient after-flush
providing syphon cistern.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is
(1) An improved wash out closet apparatus as hereinbefore described in the
Specification and illustrated by the accompanying drawings.
(2) In an improved wash out closet apparatus the basin A, having spigotted
outlet, fitting into the cup B¹ forming together a spigot and socket joint all as before
described and illustrated in the accompanying drawings.
(3) In an improved wash out closet apparatus the bend B, C, D and E, provided
with slotted flanges to enable the same to be fixed at any required angle, one with
the other all as before described and illustrated.
Dated this 19th day of June 1891.
