D‘EFECAT‘OR WITH INTEGRAL TANK ANDy
INTEGRAL EVACUATG‘R
William C. Groeniger, Columbus, Ohio, assignor
to John B. Pierce Foundation, New York, N. Y.,
a corporation of New York ,
Application April 30, 1936, ‘Serial No. 77,087
3 Claims.
This invention relates to defecators i. e., water
closets, and more particularly to- defecators com
prising a bowl with rim channel flushing means,
and a storage tank for a ?ushing liquid, usually
5 water, communicating with the rim-?ow-channel
of the bowl.
‘
The present invention has as primary objects
the elimination of whistling noises usually at
tending the flushing cycle of the above speci?ed
types of defecators, the utilization of practically
the entire liquid contents of the storage tank
during each ?ushing cycle, and the provision for
a positive after-?ll of the well of the bowl, sup
plied, in a major degree, from the normal liquid
15 contents of the storage tank.
Such objects are accomplished by providing
suitable air-venting means for the rim-?ow
channel of the defecator bowl during the ?ush
ing cycle to prevent entrapment of air therein
and thus to eliminate syphonic action common
ly operative on the supply stream from the stor
age tank to effect premature closure of the flush
valve.
Pursuant to the present invention, embodi~
ments thereof usually comprise a tank for the
storage of flushing-liquid, a defecator bowl pro
vided with a rim-'flow-channel, a discharge con

Referring to the drawings and to the therein
illustrated embodiment of this invention, the "\
unitary combination of a defecator bowl ill, a
storage tank‘ I l, and an evacuator I2 is of the
Wall-hung type and is suitably secured with its
substantially planar, Vertical back face 13 against
a wall, or equivalent, indicated at M.
Such defe-l 15
cator combination discharges laterally through
the opening l5 into component piping (not
shown) of a waste disposal system.
In the particular embodiment, the rim-?ow
channel l6 comprehends the upper periphery of 20
the bowl l0 and has branching therefrom at its
front a down?ow channel ll terminating in a
main flush-jet ori?ce I 8 anteriorly of the well
IQ of the bowl.
Also, branching from the rim
?ow-channel 16 at an appropriate location is a 25
down?ow conduit 20 terminating in the vortex

rim-flow-channel I6 is provided with a plurality .,

In a defecator embodying a rim--?ow-channel,v
for purposes of 'e?ic'iency during the ?ushing
cycle, i. e., the elimination of whistling noise,
quickness and positiveness of ?ushing action, and
utilization of substantially the entire contents of
the storage tank, it is desirable to‘ displace all
of the air in theFrim?ow channel withnwater

rim-?ow-channel to supply the after-?ll to the
well of the bowl.

Whereas, I have * described my invention by

may be made without departing from the spirit
of the invention as set forth in the following
