WATER-CLOSET."
a 11mm mm March 20, iezajser ial no, 960,540.
Toallwhomitmwy aaa;-., I, H Be it known thatI. ROBERT J MoLANn- HAN, residing at Woodlawn, in the county of Beaver and tate of: Pennsylvania, .a citizen of the United States, have invented or: disk covered certain new and useful Improve ments in -Water-Closets, of which improvements the following is a s ecific ation.
My invention; relates to, mprovements in the structure of water closets It "is-illustrated in the accompanying drawings, in which Fig. I is a view in medial and vertical section'ofthe entire installation; Fig. II is a view in horizontal section on the lane indicated by the dotted line II II, ig. I, of thesame structure; and Fig III is a view in section on an irregular surface indicated by the dotted line III-III, Fig. I, illustrating the arrangement of the passageways.
The water closet installation includes'the familiar bowl 1, flushing tank 2, and flushing pipe 3. Flushing is effected in the usual manner by unseating a valve 4, ordinarily in the form of a rubber ball, which controls passage from tank 2 to pipe 3. The flushmg pipe opens into a space within the water closet fixture itself, from which space there is connection'to a nozzle '5 (which spurts a stream into the ascending arm 6 of the siphon discharge pipe) and from which. space streams flow down the sides of the bowl 1. This space in the ordinary construction and arrangement is, when the water closet is inactive, freely open to the air. The flushingpipe 3, therefore, is at such times empty, and the lower face of the valve 4 is exposed to atmospheric pressure. The effective force tending tohold the valve 4 to its seat is therefore merely the weight of the water above it. this leakage is apt to go on, with a waste of large quantities of water in the long run. My invention consists in a particular construction within the water closet fixture itself, whereby at notime is thelower face of the valve 4 freely exposed to the atmosphere, but at all times of inaction the flushing pipe is full of water. Atsuch times the wei ht of the water in the flushing pipe ten s to create avacuum beneath the valve, and tends therefore to hold the valve more firmly to its seat. The consequence is that leakage is prevented! an escape of water,
There is apt to be leakage, and
,of the bowl.
which in the long run may amount to great quantities, is guarded against.
- 'To this end, the space within thefixture and disposed above thedischarge pipe 6 and rearward of the bowljis divided by a partition 7, the particular arrangement of which will be understood on comparing Figs. II and III. Its effect is to provide a closed conduit 8 continuons with the flushing pipe 3 and leading to a point'below the level of water standing in bowl 1 (indicated ata) and at or below the level ofthe nozzle 5. At" the lowest point, the web 9 which as usual. is spread between the parallel. reaches of the siphon discharge pipe is penetrated by an orifice lO, and a continuation 11 ofthe conduit ascends thence to the] space 12 above, and on the opposite side of the partition 7. From this space 12 the flushing stream has access to the orifices 13 through which the water emerges to wash the sides of the scends through the flushing pipe 3 and through the passageway 8 to the low point, and part of the flushing stream is there projected through the nozzle 5 to set in motion the evacuating stream through the suction discharge pipe 6. The remainder of the flushing stream passingthrough the orifice 10, and ascending through the passageway 11, and thence to the space 12, emerges through the orifices 13 and washes the walls Evacuation continues until in consequence of the 'failure of the stream,
- the suction action is ended and the remaining supply of water comes to rest within the bowl at the level a.
After a flushing operation and as the tank .2 fills again, the valve 4 will be brought to its seat by the escape of water through the -fil1s both the. flushing pipe 3 and the passa-geway 8 will be retained; there will be no escape of water through the nozzle, but the weight of the retained column of water tending to escape, will the more firmly hold the valve 4 by suction to its seat.
I claim as my invention:
1. In a water-closet structure the combination of a bowl, a siphon discharge passageway leading from the bowl, an upwardly directed nozzle opening into the ascending arm of the siphon passageway, a
flushing tank, a conduit for the flushing stream with continuous and imported walls leading from the flushing tank downward to the level of the said nozzle, and'from this point ascending to an orifice at the upper rim of the bowl, and an overflow pipei leading [from the tank and discharging into said conduit'in the region of its ascent to the oritic-e at' theupper rim of the bowl, substantially as described, i I
2.' In a water-closet structure the combination of a bowl, a siphon discharge .pas-
sageway leading from the bowl and centered in thevertical mid plane through the bowl, an upwardlydirected nozzle opening into. and ascending arm of-said siphon sageway, a flushing tank, a casing enclosing the siphon discharge passageway on either side, a vertically extending septum formed integrally with'the siphon discharge passageway and dividing the space within the a casing lass-e ding and ascending conduits, said septum, elsewhere imperf'orate, being perforated below the high cation from the casing at the upper end of the ascending conduit to the rim of the bowl, and-an ,overflow pipe leading from the flushing-tank and openi'ng't'o said casing at the ,u per end of the ascending conduit tonnes, therein as aforesaid.
Intestimony whereof I have hereunto set myhand; g
