afesaid chambei into the tank where it 11ses to a suitable height. Sutounding
the pipe and separating the tank from the chamber except through the pipe is a
plate or flange on the pipe which also catties supports for the bell which encloses
the aforesaid pipe at a suitable distance from it, from its upper end down to neal
the floor of the tank to form with the pipe, a syphon. The outlet from the chamber
below the tank is above the level of the lower end of the longer on discharge leg
of the syphon, consequently the lower end of the lattor always remains sealed and
gases cannot 11sc from the diains, sewers, or the like to which the outlet loads, uto

COMPLETE SPECIFICATION.
Improvements in or relating to Flushing Apparatus.
We, LAMBERT MULKAY and JOSEPH MULKAY, both of 33, Rue du Rouleau,
Liège in the Kingdom of Belgium, Industrial Engineers do hereby declate 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
-
This invention has for its object improvements in flushing apparatus and is shown
in the accompanying drawings, in which :-
Figure 1 is a cross section, and
Figure 2, a longitudinal section of the improved lushing apparatus
a is a tank or reservoir, b a rectangular well or chamber for receiving the lower
part of a syphon, 18 the discharge pipe, a vertical pipe with a bend at its lower
end forming, with a bell, a sy phon, e a cast metal plate, a bell held down by angle
irons or the like, g a small pipe, a tap, a plug oi valve provided with a iod for
operating it, an opening for operating the apparatus, & man hole.
The improved apparatus comprises a watcitight tank a and syphou d constructed
in the following manner :-
The tank a is closed above and provided with two domes, aud k in its covei, said
..מזל

page_text: domes being closed above by covers or doors. The bottom of the tank is lowered
or depressed at one end where the syphon is fitted and below said lower part is
constructed a chamber into which the longer leg of the syphon dips. This
arrangement has for its object to allow of the larger part of the tank bottom being
drained dry when necessary. The longer leg of said syphon 18 composed of a
pipe d elbowed at its lower end and extending upward froin within the aforesaid
chamber into the tank where it ises to a suitable height. Surrounding the pipe d
and separating the tank a from the chamber b, except through the pipe, is a plate e
or flauge on the pipe to intercept communication between chamber and the tank
which plate also carries supports for a bell which encloses the aforesaid pipe dat
a suitable distance from it, from its upper end down to near the floor of the tank a
to form with the pipe a sy phon, a suitable space being left between the edge of the
bell and the plate e An outlet pipe e from the chamber below the tank a 18
aanged above the level of the lower end of the longer or discharge leg d of the
sy phon, consequently the lower end of the latter always remains sealed and gases
cannot use into the tank from the diams, sewers on the like to be flushed, to which
the outlet leads. The elbowed end of the sy phon leg d forms an air cushion in said
83 phon leg which forces the level of the water in the tank to rise above the bell
Eo as to have a layer of water sufficient to expel the confined air and thus forto a
Таспит The tank is filled continuously through a cock in the usual way, the
disebarge being automatic and periodical as with other Bushing tanks. The filling
of the tank is regulated by and tap according to the time which is to clapse between
two fluchings. The tule g is for the purpose of admitting air after a flush, and
his a tap which must be opened when it is deaned to only make a half flush, the air
being then admitted by this tap instead of by the end of the tube g. An orifice 19
provided in the aforesaid plate or Hange and is normally closed by a valve or plug
to which a rod is attached by or through which the valve may be removed if it is
desued to empty the tank dnect to the chamber beneath it without pissage
through the sy phou.
Having now particularly descubed and ascertained the nature of our gard
invention and in what manner the same is to be performed, wo declare that what
no claim 1b
1. The improvement in Aushing apparatus consisting in downwardly extending
one leg of the flushing sy phon and forming at its lower end au elbow adapted to
always retain suflicient water to act as a seal against the return of obnoxious gases
substantially as described.
2. In a flushing apparatus of the kind described, a well or chamber formed below
the bottom of the tank to receive the discharge pipe, a syphon over said chatuber
and within the tank comprising a bell and a pipe within said bell, said pipe being
extended downward into said chamber and there formed with an elbow adapted to
act as a water seal, and a tube extending downward from the upper end of the bell
to near the bottom of the tank substantially as described.
3. In a flushing apparatus of the kind described, a tube extending downward
from the upper end of the flushing syphon to near the bottom of the tank and
having a tap about the middle of its length, whereby the apparatus may be adjustal
to produce either a full flush or a half flush as desned, substantially as set forth
4. The construction and combination of parts taken as a whole forming the
improved flushing apparatus substantially as hetembefore described and illustrated
in the accompanying drawings.
