Improvements in or relating to Lavatories, Sinks, and other like
Sanitary Appliances.
I, SAMUEL HUNT ROWLEY of Swadlincote in the County of Derby,
Earthenware Manufacturer, do hereby declare the nature of this invention to
be as follows:-
My invention has reference to lavatories, sinks and other like sanitary appliances
Euch for example as baths and its chief objects are to provide the lavatory basin,
sink or the like with a comparatively large outlet and correspondingly large plug
at a relatively small cost; to allow of the plug being removed and the waste pipe
cleaned without interfering with the other fittings; to fit a lever for operating the
plug from below in such manner that no leak can take place at the lever fittings;
to allow of the trap being placed close under the outgo of the basin; to prevent
any gases or smell getting from the waste pipe to the basin; and to hide the trap
and other fittings below the basin from view while at the same time providing that
any leak of water or liquid shall be apparent.
According to my invention I fit the waste outlet at the bottom of the lavatory
basin, sink or the like, which outlet I preferably make much larger than usual,
with a loose plug having guide wings or other guides at the underside and in com-
bination with this plug I use a lever which when acted upon by a rod, chain or
otherwise comes against the lower end of the plug and lifts it so as to open the
waste outlet. When the lever ceases to press up the plug this descends of its own
weight and closes the outlet. The lever is not in any way attached to the plug;
the latter can therefore be lifted out at any time to allow the waste pipe to be
cleaned. The lever above described is pivotted on a spindle situated within a
chamber or box which is open to the waste pipe or outgo of the basin; one end of
this spindle passes through a packed aperture in the side of the said chamber and
has connected to it outside the chamber an arm by which the spindle can be turned
by the rod, chain or other actuating device and the lever thereby operated. By
this arrangement no liquid from the waste pipe can escape at the lever fittings. In
some cases I use a second loose plug situated at top of the waste pipe the two plugs
being in this case lifted simultaneously from below by a lever as above explained
when it is desired to run off the contents of the basin. The upper plug may be
loosely fitted upon a vertical pin projecting up from the lower plug. The space or
chamber between the two plugs can be in communication with the water supply
and in such case when the supply is turned on the water lifts the upper plug and
enters the basin; when the supply is shut off the plug closes by gravity. There'
may be a grid between the two plugs or below the lower plug. When the water
is supplied through the bottom of the basin as above described a channel may be
carried up outside the basin from the space between the two plugs so that the water
always rises in this channel to the same height as in the basin. From the top of
this chanuel the water overflows into and runs down another channel or pipe to the
waste pipe or otherwise. With this construction no overflow apertures arc
required in the basin. Below the basin I fit a removable casing, which may be of
any desired ornamental character, to enclose the trap and fittings from view. This
casing does not come close up against the waste pipe below the trap although
appearing to do so; there is on the contrary a space of half an inch more or less

page_text: between them so that in case of any leakage from the joints or fittings the
leaking liquid will run down between the pipe and casing and show itself outside
the pipe. The waste pipe or so much of it as is between the level of the bottom
of the casing and the floor can be made ornamental or have an ornamental
shield.

Improvements in or relating to Lavatories, Sinks, and other like
Sanitary Appliances.
1, SAMUEL HUNT ROWLEY of Swadlincote in the County of Derby, Earthen-
ware Manufacturer, do hereby declare the nature of the said 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 has reference to lavatories, sinks and other like sanitary appliances
such for example as baths, and its chief objects are to provide the lavatory basin,
sink or the like with a comparatively large outlet and correspondingly large plug
at a relatively small cost; to allow of the plug being removed and the waste pipe
cleaned without interfering with the other fittings; to fit a lever for operating the
plug from below in such manner that no leak can take place at the lever fittings;
to allow of the trap being placed close under the outgo of the basin; and to hide
the trap and other fittings below the basin from view while at the same time
providing that any leak of water or liquid shall be apparent.
According to my invention I fit the waste outlet at the bottom of the lavatory
basin, sink or the like, which outlet I preferably make much larger than usual,
with a loose plug having guide wings or other guides at the underside, and in
combination with this plug I use a lever which when acted upon by a rod, chain or
otherwise comes against the lower end of the plug and lifts it so as to open the
waste outlet. When the lever ceases to press up the plug this descends of its own
weight and closes the outlet. The lever is not in any way attached to the plug ;
the latter can therefore be lifted out at any time to allow the waste pipe to be
cleaned. The lever above described is pivotted on a spindle situated within a
chamber or box, which is open to the waste pipe or outgo of the basin; one end of
this spindle passes through a packed aperture in the side of the said chamber and
has connected to it outside the chamber an arm by which the spindle can be turned
by the rod, chain or other actuating device, and the lever thereby operated. By
this arrangement no liquid from the waste pipe can escape at the lever fittings.
In some cases I use a second loose plug, situated at top of the waste pipe, the two
plugs being in this case lifted simultaneously from below by a lever as above
explained when it is desired to run off the contents of the basin. The upper plug
may be loosely fitted upon a vertical pin projecting up from the lower plug. The
space or chamber between the two plugs can be in communication with the water
supply, and in such case when the supply is turned on the water lifts the upper
plug and enters the basin; when the supply is shut off the plug closes by gravity.
There may be a grid between the two plugs or below the lower plug. Below the
basin I fit a removable casing, which may be of any desired ornamental character,
to enclose the trap and fittings from view. There is an opening in the casing, so
that in case of any leakage from the joints or fittings the leaking liquid will run
down between the waste pipe and casing, escape through this opening and show
itself outside. The waste pipe, or so much of it as is between the level of the

page_text: bottom of the casing and the floor can be made ornamental or have an ornamental
shield.
Figures 1, 2 and 3 of the accompanying drawings represent a lavatory in which
my improvements are embodied, the basin being provided with two plugs as
herein before described.
Figure 1 is a vertical section on the line A-B of Figures 2 and 3, Figure 2 is
a back elevation and Figure 3 a plan.
Figure 4 represents in vertical section a modification in which the basin has only
one plug.
Referring first to Figures 1, 2 and 3, a is the basin, b the outlet of same, c the loose
plug to the outlet, this plug having guide wings d at the underside e is a second
loose plug situated at the top of the waste pipe f. g is the trap. The upper plug cfits
loose upon a vertical pin projecting up from the lower plug e; this lower plug
rests upon a lever to which it is not attached. The said lever is pivotted on a
spindle k situated within a chamber which is open to the waste pipe f; one end of
the spindle k passes through a packed aperture in the side of the chamber / and
has connected to it an arm n by which the spindle k can be turned by means of the
rod P, the upper end of which is fitted with a knob or handle g. The lever j can
thus be operated by means of the knob q so as to lift the plugs cand e and thereby
allow the water to flow from the basin a through the waste pipe f to the trap y.
When the lever is again lowered the plugs close by gravity. rands are the cold
and hot water supply respectively; they communicate by channels t t with the
space between the two plugs c and e, so that when the supply is turned on the
water lifts the upper plug and enters the basin. When the supply is shut off
the plug closes by gravity.
u is the removable casing hereinbefore described to enclose the trap g and
fittings from view. This casing has an opening at its lower part, so that in case
of any leakage from the joints or fittings, the leaking liquid, after running down
between the waste pipe fand casing u will escape through this opening and show
itself outside. ww represent an ornamental shield covering the portion of the
waste pipe which is between the casing u and the floor, that is to say the portion f'
which is beyond the trap 9..
The lavatory shown in Figure 4 differs from that shown in Figures 1, 2 and 3
chiefly in that the basin has only one plug c and that the water supply does not
reach the basin through the plug.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. In a lavatory, sink or other like sanitary appliance, a loose plug to the waste
outlet in combination with a lever for lifting the plug, the lever not being attached
to the plug and being pivotted on a spindle in a chamber open to the waste pipe,
one end of the said spindle passing through a packed aperture in the chamber
and having connected to it a device by means of which it and the lever can be
turned so as to lift the plug, substantially as and for the purpose hereinbefore
described.
2. In a lavatory or other like sanitary appliance, the combination with a loose
plug to the waste outlet and with a lifting lever as referred to in Claim 1, of a
second loose plug at the top of the waste pipe, so that when the lever is operated
it lifts the two plugs simultaneously, substantially as and for the purpose
hereinbefore described.
3. In a lavatory or other like sanitary appliance, the combination with two loose
plugs and a lifting lever as referred to in Claim 2, of a water supply connected
with the space between the two plugs so that the water enters the basin from
below by lifting the upper plug, substantially as hereinbefore described.
4. In a lavatory or other like sanitary appliance, a removable casing below the
basin to enclose the trap and fittings from view, the said casing having an opening

page_text: through which any leaking liquid from the joints or fittings, after passing down
between the waste pipe and casing escapes and shows itself outside, substantially
as set forth.
