I, BENJAMIN ROBINSON, of Church Gresley in the County of Derby Sanitary
Earthenware Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to water closets and mainly consists in the construction of.
the basin with a hollow rim which constitutes or takes the place of an after-service
box and in providing for a double bottom flush.
I will proceed to describe a water closet basin constructed in accordance with my
invention.
The rim or upper edge of the basin is made hollow for the whole or part of its
extent and is in communication with the inlet nozzle by which the flushing water is
supplied to the basin. Thus when the water passes through the nozzle to the fan or
spreader so as to flush the basin in the usual manner, some of it will pass directly
from the nozzle to the hollow rim and charge or fill the same. Then when the flush
of water ceases the water in the rim will run through one or more comparatively
small apertures in the lower part of the fan or spreader so as to provide the usual
after supply to the basin. For carrying out this part of the invention the fan or.
spreader is of special construction, that is to say, that in addition to the side wings
with apertures through which the water escapes so as to flow round the basin as
usual, it has a downward extension at the bottom of which are the small aperture
or apertures for the flow of the after supply from the rim.
For the bottom flush there is a pipe or channel carried down from the inlet
nozzle to apertures at the lower part of the basin, but in addition to a single row
of apertures which have been sometimes here formed below the normal water level

page_text: in the basin for the purpose of flushing or carrying away the contents of the basin I
form one or more holes at a higher level so as to produce with the lower row of
apertures a double flush. The water admitted through the upper hole or holes may
be made to strike the water at any desired point and it ensures the carrying away of
paper and floating soil which the flush from the lower apertures is liable to leave
behind.
My invention applies more particularly to basins of the wash-out type.

page_text: I BENJAMIN ROBINSON of Church Gresley in the County of Derby, Sanitary
Earthenware Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascertained
n and by the following statement :—
My invention relates to water closets and mainly consists in the construction of
the basin with a hollow rim which constitutes or takes the place of an after-service
box, in a special construction of fan or spreader, and in providing for a double
bottom flush.
1 will proceed to describe a water closet basin constructed in accordance with
my invention.
The rim or upper edge of the basin is made hollow for the whole or part of its
extent and is in communication with the inlet nozzle by which the flushing water is
supplied to the basin. Thus when the water passes through the nozzle on its way to
the fan or spreader so as to flush the basin in the usual manner, some of it will pass
directly from the nozzle to the hollow rim and charge or fill the same.
Then when the flush of water ceases the water in the rim will run through one
or more comparatively small apertures in the lower part of the fan or spreader so
as to provide the usual after supply to the basin. For carrying out this part of the
invention the fan or spreader is of special construction, that is to say that in
addition to the side wings with apertures through which the water escapes so as to
flow round the basin as usual, it has a downward extension at the edge of which
are the small aperture or apertures for the flow of the after supply from the rim.
For the bottom flush there is a pipe or channel carried down from. the inlet
nozzle to apertures at the lower part of the basin, but in addition to a single row
of apertures which have been sometimes here formed below the normal water level
in the basin for the purpose of flushing or carrying away the contents of the basin
I form one or more holes at a higher level so as to produce with the lower row
of apertures a double flush. The water admitted through the upper hole or holes may
be made to strike the water in the basin at any desired point, and it ensures the
carrying away of paper and floating soil which the flush from the lower apertures is
liable to leave behind.
My invention applies more particularly to basins of the wash out type.
The accompanying drawings represent a water-closet in which my improvements
are embodied. Figure 1 is a section on the line x-x of Figure 2 and Figure 2 a
section on the line y-y of Figure 1.
a is the basin, the form shown being of what is known as the "wash out" type. bis
the inlet nozzle, c is the fan or spreader in communication with the inlet nozzle by
the opening d. e is the rim of the basin made hollow as before described; it is in
communication with the nozzle by the hole or opening f and with the back of the fan
by the hole or opening g. The fan is of special construction; it has side wings h h

page_text: with apertures at the ends through which the water issues so as to flow round the
basin and it has also a downward extension i at the edge of which are small apertures k
(one or more as thought best) for the discharge of the after supply from the rim ;
there may also be small apertures at the lower edge of the wings h for the same
purpose. It will readily be understood that when the water passes through the
nozzle on its way to the fan or spreader c so as to flush the basin some of it will
pass through the hole f to the hollow rime and charge the same. Then when the
main flush of water ceases the water in the rim will run through the hole g to the
back of the fan c, and then through the small apertures and provide the after flush.
Of course during the main flush some water will pass through the apertures k, but
this is of advantage. The particular form or construction of fan or spreader
described and shown, that is to say with the side wings h h having apertures through
which the water issues so as to flow round the sides of the basin, and with the
downward extension i having small apertures at the edge will be found useful
for closets which are not made with a hollow rim as described.
is a channel leading from the nozzle b to the apertures through which the
water for the bottom flush issues. These apertures consist of a row or set m below
the normal water level in the basin, and of an upper row or set n at a higher level.
The two rows produce a double bottom flush. According to the height and angle or
inclination of the holes of the upper row the issuing water will strike the water in the
basin at a greater or less distance from the holes. It ensures the carrying away of
paper and floating soil which the flush from the lower apertures is liable to leave
behind. A third row of holes may be formed above the row n, but I have found
the two rows sufficient.
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 in respect of water closets is:
1. A basin formed with a hollow rim which becomes charged or filled with
water during the main flush, and afterwards discharges itself into the basin, thereby
acting as or taking the place of an after-service box, substantially as hereinbofore
described.
2. The special construction of fan or spreader with side wings having apertnres
for the flushing water, and with a downward extension having small apertures at
the edge as hereinbefore described.
3. The combination with a row or set of holes below the normal water level in
the basin, of one or more other rows or sets above the first named row or set,
substantially as hereinbefore described, whereby a double bottom flush is obtained
and the washing away of paper and floating soil ensured.
