COMPLETE SPECIFICATION.
Improvements in Water Closets.
I, WILLIAM BUNTING, Junior, of Brooklyn, in the County of Kings, and State of
New York, United States of America, Manufacturer and Inventor, do hereby declare
the nature of my invention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:
My invention relates more particularly to that class of water-closets known as the
"Bostel" patent closets.
My invention has for its object to improve this species of water-closet, and not
only avoid the objection hitherto urged against the same, but at the same time
effect a considerable saving in cost therein; and to these main ends my invention
consists in the features of construction hereinafter more fully described and particu-
larly pointed out in the appended claims.
In the drawings accompanying this specification and forming a part thereof,
Figure 1, is a top or plan view of a water-closet embracing my improvements.
Figure 2, is a central vertical section of the same.
Figure 3, is a side elevation thereof, with the ventilating-cover in place.
Figure 4, is a vertical section taken at the line y, y, of figure 1, with the cover
on and looking in the direction of the arrow thereat, and
Figure 5, is a similar soction taken at the line a, x, of figure 1, viewed in the
direction indicated by the arrow at said line.
In the several views the same parts will be found designated by the same numerals
of reference.
The water-closet is made of a single piece of porcelain or earthenware and consists
primarily of a bowl or basin 2, a vertical trunk or chamber 3, a trap 4, and an
outlet 5. The bottom of the bowl is made dishing as seen at 6, to hold a small body
of water at all times, and the top of the bowl is provided with a flushing-rim 7,
having a slot 8 at the front of the bowl, and a series of perforations 9, around each
side of the bowl for the discharge of the flushing water.
The trunk is located at the rear of the closet and about centrally of the bowl. It
is curved or bent forward slightly at its upper end and is formed with an opening 10,
through which access may be obtained to the trunk and trap and through which
these portions may be ventilated, by means of the hollow cover 11.
Formed integral with the bowl and the upper portion of the trunk, are con-
duits 12, 12, which extend rearwardly from the bowl, to a vertically arranged inlet-
nozzle 13, formed at the upper end of the trunk about centrally of the structure
lengthwise.
These conduits are arranged one on each side of the trunk and, converging, meet
at the inlet nozzle 13, at the rear of the closet. The forward ends of the conduits
communicate with the flushing-rim 7 on each side of the center at the rear of the
bowl, and the rearwardly-extending portions are preferably depressed slightly, as
shown, in order that the ventilating cover 11 may not project above the plane of
the bowl and interfere with the proper fitting of the seat and wood-work surrounding
the closet. The passage-ways in the conduits are shown in dotted lines at figure 1.
The conduits it will be seen, are made bulging or in relief exteriorly and are joined,
for their full length, to the bowl and the trunk along the irregular line 14, and finally
vanish into the inlet-nozzle on opposite sides thereof.
In addition to the union along the line 14, the conduits are united to the bowl and
the trunk and to each other by a horizontally-arranged stay or web 15, as seen at
figure 1, which further strengthens the structure.
The inlet-nozzle is preferably arranged to terminate in a vertical direction to save
the expense of a bend from the usual vertical supply-pipe from the flushing tank.

page_text: The bore of the inlet-nozzle is curved from near its upper end to terminate in a
horizontal direction at the junction of the horizontally-arranged conduits.
From the bottom of said inlet-nozzle above the plane of the dish or receiver 6,
extend downwardly in an oblique direction, one or more perforations 16, which
during the flushing operation emit a stream or streams against the inner vertical
wall of the trunk for the purpose of removing any light pieces of paper which may
have clung thereto, and which also after the cessation of the flushing-operation serve
to carry
off any surplus water in the conduits and inlet-nozzle.
To the upper end of the inlet-nozzle is connected by the coupling shown, or by any
other suitable means, the supply-pipe 17, which as usual is attached to the flushing-
tank or other source of water-supply.
In the operation of the closet, the flushing-water, descending through the supply-
pipe, enters the inlet-nozzle and passes thence into the conduits or channels 12, 12,
on either side, from which the two separate bodies of water are directed into the
flushing-rim 7, one on each side, and rushing around the same, are caused to meet at
the front of the bowl. During the passage of water round the flushing-rim, small
streams are discharged through the perforations 9, to wash down the walls of the bowl,
but the bulk of the water is discharged at the slot 8, and by its force and direction
the contents of the receiver or dish 6, are carried rearwardly into the trunk, through
the trap and the outlet to the sewer or waste connections.
It will be seen that by my invention is provided a closet of the wash-out, side-
delivery typo in which the flushing-rim inlets are made of a piece or integral with
the bowl and trunk, and extend rearwardly around the opening in the trunk to the
inlet from the supply-pipe, whereby a structure of great strength is produced and one
in which the objections made to prior closets of this description are wholly obviated.
It will be seen furthermore, that by making the inlet-nozzle and branches one and
the same piece, and forming them integral or en masse with the bowl and trunk,
instead of making two projecting inlet-nozzles and uniting these in the fitting up of
the closet by metallic connections or branches and bends as heretofore, I am not only
enabled to avoid the expense of making two connections but also the considerable
expense of the metallic fittings which must accompany such prior construction of
closets.
If desired the inlet-nozzle may be arranged to terminate in a horizontal direction,
and other variations may be made without departing from the spirit of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. In a water-closet having a bowl provided with a flushing-rim and having also a
trunk, the two rearwardly projecting conduits formed integral or of a piece with the
bowl and trunk communicating with the flushing-rim on opposite sides and extending
therefrom around the trunk to a common inlet-nozzle; substantially as shown and
described.
2. In a water-closet having a bowl provided with a flushing-rim and having also
an open trunk, the two rearwardly-projecting conduits formed integral or of a piece
with the bowl and trunk, communicating with the flushing-rim on opposite sides,
extending therefrom around the trunk-opening, to a common inlet-nozzle, and con-
nected to each other at the front side of said opening by a web or ligament made
integral therewith; substantially as shown and described.
3. In a water-closet having a bowl provided with a flushing-rim and having also a
trunk, the two rearwardly-projecting conduits joined to the bowl and the trunk and
communicating with the flushing-rim on opposite sides and extending to and com-
municating with a vertically-terminating inlet-nozzle; the bowl, the flushing-rim, the
trunk, the conduits and the inlet being all made from a single piece of earthenware;
substantially as shown and described.
4. A water-closet consisting of a bowl provided with a flushing-rim and a dish or
basin, a vertical trunk in rear of the bowl, two rearwardly-projecting conduits formed

page_text: integral with the bowl and trunk and extending from the flushing-rim on opposite
sides, and a vertically-terminating inlet-nozzle at the junction of said conduits provided
with one or more perforations extending to the inner vertical wall of the trunk above
the plane of the bowl's dish, whereby a stream or streams of water may be discharged
upon said wall for the purpose of removing any matter which in the wash-out of the
basin may have lodged thereon; substantially as shown and described.
