I, JOHN SHANKS, of Tubal Works, Barrhead, in the County of Renfrew, North
Britain, Sanitary Engineer, do hereby declare the nature of this. invention to be
as follows, that is to say:-
My said invention has for its object to improve the construction or combina-
tion of parts constituting the waste or discharge apparatus of sinks, washing
vessels, baths, lavatories, and the like; and to render such parts less liable to get
out of order, and more easily kept clean.
In carrying out my invention I make the interior of the bottom of the sink
or other vessel with a conical depression communicating with the waste outlet,
but having a check or internal shoulder to support a grating. The discharge
valve is applied above the grating, and is disk-shaped and made with a projecting
rim of rubber or other suitable flexible material adapted to become seated in the
conical depression. The valve may be connected to a chain, or other retaining
appliance. The overflow passage enters the outlet between the grating and the
bottom orifice; and its upper part is, preferably open at the top, and its entrance
from the sink or vessel is a broad opening with a perforated covering or grating,
or preferably without.
The outlet orifice is flush or nearly flush with the bottom of the sink or vessel,
and according to one modification, the flanged end of the waste pipe, or of a
nozzle or tail piece or trap to which the waste pipe is attached, is secured
by one or more screws to the grating. Or the grating may be made with a
tubular part extending down through the outlet orifice, a screw nut securing it
externally, and the waste pipe being connected to it by screw coupling or other-
wise. Instead of the conical seat being formed in the material of the vessel it
may be formed in the same piece as and above the grating.

Improvements in and connected with Waste or Discharge Valves of
Sinks, Washing Vessels, Baths, Lavatories, and the like.
I, JOHN SHANKS, of Tubal Works, Barrhead, in the County of Renfrew, North
Britain, Sanitary 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, that is to say:-
My said invention has for its object to improve the construction or combina-
tion of parts constituting the waste or discharge apparatus of sinks, washing

out of order, and more easily kept clean.
And in order that my said invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings
to be hereinafter referred to and showing in vertical section, two modifications of
my improvements.
In carrying out my invention as shown in Figure 1, I make the interior of the
bottom of the sink or other vessel, A, with a conical depression, B, communi-
cating with the waste outlet, C, but having a check or internal shoulder, D), to
support a grating. E. The discharge valve, F, is applied above the grating, E,
and is disk-shaped and made with a projecting rim, G, of rubber or other suit-
able flexible material adapted to become seated in the conical depression, B. The
overflow passage, H, enters the outlet, C, between the grating, E. and the bottom
orifice and its upper part is, preferably, open at the top, and its entrance from
the sink or vessel. A, is a broad opening with a hinged perforated covering or
grating, J, to which a chain, K, attached to and extending up from the discharge
valve, F, is secured. The outlet orifice, C, is in this modification, flush with
the bottom of the sink or other vessel, A, and the flanged end of the waste
pipe, or of a nozzle or tail piece, L, (or it may be a trap) to which the waste pipe
may be attached, is secured by screws, M, passed down from the upper side of the
grating, E, and of such a length that their lower ends will enter holes formed
for them in the upper edge of the tail piece, L, the screwing action, at the same
time, drawing the flange, N, of that piece tight against the bottom of the sink, A.
In the modification shown in Figure 2, instead of the conical seat, B, being
formed in the material of the vessel, as in the first modification, it may be formed
in the same piece as and above the grating, E, and where desired the check or
internal shoulder, D), may be dispensed with. The grating, E, is made with a
tubular part, P, extending down through the outlet orifice, C, a screw nut, Q,
securing it externally, and the waste pipe or tail piece, L, is connected to it by a
screw coupling, R. In this modification the hinged perforated cover (J), is
dispensed with.
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 connection with waste or discharge valves of sinks, washing vessels, bath
lavatories, and the like a conical seat for a flexible-rimmed valve made in the
bottom of the vessel above a grating or in the same piece as and above the grating,
the grating having attached to it by screws the upper end of a waste pipe or
connecting piece substantially as herein before described.
2. In connection with waste or discharge valves of sinks, washing vessels,
baths, lavatories and the like, a conical seat for a flexible-rimmed valve made
in the bottom of the vessel above a grating or in the same piece as and above the
grating, the grating being made with a tubular part extending down through the
outlet orifice, a screw nut securing it externally, and a waste pipe or connecting
piece being connected to it by a screw coupling substantially as hereinbefore
described.
