1 Claim. (01. 4-73)
Under the conventional practice of starting si
phonic action in water closets by means of a jet,
the degree to which the jet is effective is depend
ent on the amount and velocity of water delivered
to the jet less the friction resulting from ?owing
through the jet.
Smooth channels having few
turns are factors determining the velocity of the
jet water, and it is the object of the present in
vention to provide a closet construction in which
10 the water is delivered to the jet in a most direct
manner, so that friction losses, which would oth
erwise lessen the velocity, are reduced to a mini
mum. Further, it is an object to provide a closet
construction in which the rim jets perform only
15 the wash-down function and in which the water,
after delivery to the closet, is divided, a part pass
ing to the rim and the remainder to the jet. .Ad
ditionally, it is an object of the invention to pro
vide a closet construction of the kind indicated,
20 which is of simple form and, therefore, suscep
tible of cheap manufacture.
With this object in View, the invention consists
in a construction and combination of parts, of
which a preferred embodiment is illustrated in
the accompanying drawing, wherein:
Figure 1 is a central vertical sectional View of a
closet constructed in accordance with the inven
Figures 2, 3 and 4 are sectional views on the
30 planes indicated by the lines 2-2, 3-3 and 4—4
respectively of Figure 1.
In the present invention the jet I0 is disposed
in the well II in facing relation to the intake I2
of the trap of the closet and the flush water is
35 delivered to it from the intake chamber I 3, which
is disposed above the trap, whose globular forma
tion where the up and down legs connect forms
the bottom of the chamber. A jet chamber I4 is
formed in the Well of the closet and this chamber
40 is in communication with the intake chamber I3
through channels or ducts I5 that may be secured
either through drain casting or the insertion of
clay partitions, but which are preferably secured
by the super?cial application of tubular conduc
45 tors laid on the sides of the closet and incorpo
rated with the latter by ?lling in around them
before the closet is placed in the kiln. The con
ductors I 5 communicate with the intake chamber
I3 on opposite sides. Either one conductor I5
50 placed on one side of the closet may be employed
or the conductor may be duplicated on the other
side, as shown, in which case the flush water
leaves the chamber I3 at similarly positioned
points on opposite sides and in like manner enters
55 the jet chamber I4.
When the flush tank is attached, the chamber
I3 becomes inaccessible, but in each ?ushing of
the closet, the chamber I3 is practically emptied,
except for such water as may be trapped in the
rear portion I6. The freezing of such trapped 5
water, however, will not be attended with any
injury to the closet, since the walls of the cham
ber I5 at the section I6 are generally divergent
and, therefore, are relieved of any direct pres
sure by the forming ice.
Since the conductors I5, after application, be
come integral parts of the closet, the glazing op
eration results in complete concealment of them,
as the ?lling in around the conductors prior to
the glazing gives a general contour pleasing to
the eye.
The super?cial application of the conductors
makes possible a placing of the intake and jet
chambers in communication through ducts or
channels that are free of slight projections that 20
would constitute obstructions interfering with the
free flow of the jet water and, therefore, reduce
the Velocity at which it is delivered to the jet.
The jet I0 is of generally oval form. This re
sults in quick movement of the dead water in the 25
up-leg of the trap and, therefore, in quick starting
of siphonic action.
The Wash-down function is accomplished by
means of water delivered to the channel I‘! formed
in the rim I8, this channel being in communica 30
tion with the intake chamber I3 through a port
or opening' I9. The rim 'on the under-side is
formed with a series of spaced ports 20 which
communicate with the channel IT. The ports 20
are downwardly inclined toward the inner face
of the bowl and are likewise inclined downwardly
toward the left, considering the rim as being
viewed from the top. In other words, the axes of
the ports 20 are arranged to follow left-hand spi
rals in the surface of an imaginary cone, so that
the water issuing through them will be given a
left-hand swirl, thereby intensifying the natural
water swirl in this latitude, which is left-handed.
In the flushing operation, when Water is ad
mitted to the entrance chamber I3 from the ?ush
tank, one part passes through the port I9 to the
channel ll of the rim and the other part to the
jet chamber I4, from which it issues in the form
of a crescent shaped jet and passes into the up
leg of the trap. The amounts of water delivered
respectively to the rim channel and the jet cham
ber are determined by the proper proportions of
the conductors I5. If there be two of such con
ductors applied, one on each side of the closet,
as shown, the capacity of each for a given quan 55
tity of water need be only half that necessary to
be provided where only one is used.
The jet, being in facing relation to the up-leg
of the siphon, is above the level of the bottom of
Cl the wall and the ducts 15, at every point, in their
lengths are above the level of the well bottom.
Thus the jet water does not have to move a great
body of still water in starting the siphonic action,
the arrangement being such that the jet has only
10 to start movement of the water in the up-leg of
the siphon.
This construction also provides for
Having described the invention, what is claimed
as new and useful is:
A water closet bowl having a trap with its intake
in the well thereof, a jet disposed in the well in
facing relation to the intake of the trap but above
the plane of the bottom of the well, and a water
intake chamber disposed on top. of the trap and
on the opposite side of the bowl from the jet but
above the plane of the latter,’ the bowl having
ducts incorporated therewith to place the intake 10
chamber in communication with the trap, the
complete removal of the water when draining the ' ducts extending around the bowl from the cham
closet, without having to take it from concealed ber to the jet at a gradual inclination with no
chambers. A siphon tube placed in the bottom
of the well, by removing the water at that point,
will completely remove all of the contained water,
or the water may be removed readily by mopping
it up.
points in their lengths being below the plane of
the jet.
