Improvements in Apparatus for Water Closets, Lavatories,
and the like.
I JOHN WILLIAM HOLLAND 23 Sparsholt Road Upper Holloway in the county of
Middlesex Engineer do hereby declare 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 relates to improvements in the method of and means for flushing
basins, pans, or other receptacles such as closets, slopsinks, lavatories and the like
whereby the distribution of the water or other liquid is regulated to a nicety and at
the same time a perfect flush to the basin or other vessel is ensured.
The invention is carried out as follows and will be understood by reference to the
drawings hereunto annexed in which,
Fig. 1 represents a section of pan or basin of a water closet in which the rim
hereinafter described is detachable.
Fig. 2 represents in section a modification in which the rim is formed partly out
of the material of which the pan or basin is composed.
Fig. 3 is a sectional view of an ordinary basin with turn down rim showing method
of attaching detachable rim.
Fig. 4 represents a basin showing slot through which the inlet pipe of rim passes,
and also the clips for supporting the rim.
Fig. 5 is a section of a modification shewn in Fig. 2.
Figs. 6, 7 & 16 show brackets for carrying rim.
Figs. 8, 9, 10, & 11 are sections of tubular rims showing different forms of holes or
slots.
Figs. 12 & 14 show a form of rim with brackets for attaching to underside of
seat.
Figs. 13 & 19 show methods of attaching the rim to basins of ordinary form by
means of cement.
Fig. 15 shows method of supporting rim in basin provided with slots.
Figs. 17 & 18 show another modification in which the rim is hinged leaving the
basin clear for cleansing &c.
Figs. 19 & 20 show another modification in which the rim is supported on a basin
having an outer flange.
Fig. 21 shows a rubber joint for connecting rim to water service pipe.
Similar parts are represented by the same letters.
A tube or its equivalent, hereinafter called a rim, for flushing, or conducting water
or other liquid to, and distributing it within, a closet basin, slop sink, or such like
vessel, hereinafter referred to as a "basin," made of metal or other suitable material
(other than earthenware) is attached to the inside of a basin upon or a little below
the upper edge. The tube has in its lower part, when in position as hereinafter
described, a series of holes or slots-A is the basin, B the rim, C the holes or slots.
Water or other liquid is conducted from a cistern or other source of supply, to the
tube or rim B, and finds an outlet through the said holes or slots C, and the jets of
liquid thus formed strike with force against the inner surface of the basin and effect
a thorough cleansing of the same.
My invention may be used in combination with existing basins as hereinafter
described but I find it better to have basins made without any inner rim or projection
at top as shown in Figs. 1-2-4-15-17 & 19° a hole or a slot or recess D being
provided when necessary for the supply pipe to pass through.
I form by casting, drawing, building up or otherwise, as will be well understood,
by Plumbers and Sanitary Engineers, a rim B which may be of any desired section
such, for instance, as those shown, in Figs. 8, 9, 10 & 11, so that it may lie snugly

page_text: within the basin upon or a little below its upper edge. This rim has a nozzle E
to which is attached by means of a screw union, or other joint, the pipe which
conducts a supply of liquid. I attach to the rim B, by soldering any convenient
number of metal strips to form clips for retaining the rim in its place. These
strips may be of copper, zinc or other metal and are bent over the top edge of the
basin and firmly pressed against the outside as shewn at F in Figs. 1 & 4. The
rim is thus held firmly in its place.
Instead of the strips or clips F passing over the top edge of the basin I some-
times employ brackets such as is shewn in Fig. 6. The screws of these brackets pass
through holes provided in the basin and are secured by nuts G on the outside. The
rim rests upon, or in, these brackets. The brackets may be analogous to S hooks
as shewn in Fig. 7 the bend I being bent over the top edge of the basin and pressed
against the outside as shown at F in Figs. 1 & 4 the rim will then lie in the bend J.
Another way in which I sometimes attach the rim is by making slots in the top of
the basin see Fig. 15 and forming on the metal rim straight or bent attachments H
which lie or rest therein. These attachments may be secured or tightened in the
basin by nuts similar to those provided on the brackets Fig. 6.
Another mode I sometimes adopt is to form the top of basin with an outer
flange T Figs. 19 & 20 and the rim is provided with lugs or continuous flange U
Figs. 19 & 20 (which may be attached at any point upon its outer circumference)
and is supported thereby upon the outer flange T of basin. The 2 flanges T & U
may be fixed together by means of bolts and nuts if desired although this is not
always necessary.
I find these methods of retaining the rim very advantageous as they allow of the
removal of the rim for cleansing purposes and the facility with which it can be
removed admits of a broken basin being replaced at small cost.
The holes or slots C in the under side or lower part of the rim B may be circular,
oval, or any other desired shape and they may be made at regular intervals, or
otherwise, or they may be so regulated, or spaced, as that they, may be small, or
narrow, or scarce, at that part of the rim where the pressure of liquid is (comparatively)
great, and larger, or broader, or more numerous, at that part of the rim where the
pressure is low.
The joint K in Figs. 17 & 18 may be hinged or flexible, instead of a rigid union
and the rim instead of being attached to the basin may be attached to the underside
of the cover of a slop sink, or of the seat of a water closet, as shewn in Fig. 17 so
that the rim will be raised when the cover or seat is raised.
The rim is secured to the cover or seat by brackets L Fig. 14 or flange M Fig. 12
which may be fastened by turnbuckles N Fig. 17 or by wood screws passing through
holes provided for that purpose. The rim can then be removed for cleaning or
repairs without difficulty. The axis of the joint K must coincide with the axis of
the cover or seat and this can be effected in the manner shewn in Figs. 17 18 & 21.
When the joint K is hinged it may be constructed as follows 2 elbows X & Y are
connected by a socket joint Z and made sound by means of packing, a, and stuffing
nut, b. One elbow is connected to the inlet pipe E and the other to the water service
pipe W.
When the joint K is intended to be made flexible it is constructed as follows-
A short piece of india rubber tubing, or piping of other flexible material is slipped
over the inlet pipe E and firmly attached thereto by tying, binding, or other suitable
means. The end of Water Service pipe W is slipped into the other end of flexible
tubing a joint is then made as before described.
This arrangement is particularly useful for slop-sinks and combination closets.
As a modification of my invention the rim may be partly formed in the material of
which the basin is composed as shewn at O in Figs. 2 & 5. This part of the rim is
covered by a strip of metal P forming a flange or shield secured at its upper-part to
the basin by bolts & nuts.
In this arrangement the liquid will be ejected in a sheet between the basin and
the lower edge of the strip of metal.

page_text: When I use an ordinary basin I attach the rim B to the basin A by means of clips
of the form shewn in Figs. 3 & 16. Fig. 3 is a section of a basin and shows how
such a clip is adjusted. The clip consists of a strip of metal bent as shewn at
Fig. 16 the rim will then lie in the bend R. The clip is supported by the part S
resting upon the top or upper rim of the basin.
The rim may also be fixed by being bedded inside the top of basin with plaister of
Paris, cement, or other adhesive or suitable material as shewn in Figs. 13 & 19.
These arrangements for fixing my improved rim to ordinary basins may be
modified to suit the particular form of basin or shape of rim.
Having now described the nature of my said invention and in what manner the
same is to be performed I wish it to be understood that I do not claim as my
invention the rim B hereinbefore described nor do I claim the method of flushing by
means of jets of liquid but I declare that what I claim is :-
1. In a water closet, slop sink, lavatory or the like, the combination of a flushing
rim B with a basin or other receptacle in the manner and for the purpose sub-
stantially as hereinbefore described and illustrated.
2. A flushing rim of the kind hereinbefore described and illustrated for flushing a
basin or the like when made detachable in the manner substantially as hereinbefore
described and illustrated.
3. In a water closet, slop sink, or the like, a flushing rim of the kind hereinbefore
described, and illustrated, attached to the underside of a cover or seat, and jointed
to the supply pipe in the manner substantially as herein before described and
illustrated.
