PROVISIONAL SPECIFICATION.
Improvements in Fittings for Baths and Lavatory Basins.
I, OSCAR ELPHICK of Lambeth Sanitary Engineering Works, Lambeth in
the County of Surrey do hereby declare the nature of this invention to be as
follows:-
I arrange as follows the fittings connected with the waste water outlet from
a bath.
A grating is secured by a bayonet or other joint into an aperture in the bath
bottom and beneath the aperture a valve seating is provided. The seating is at
the entrance to a trap which with a flange joint is bolted on beneath the bath; the
valve seating is confined in its place in the joint which connects the trap.
A tubular plug works through an opening in the centre of the grating, its lower
end is armed with a ring of india rubber which abuts on the valve seating and
serves as the valve. A short lift of this valve opens a wide passage by which the
waste water passes from the bath, flowing through the grating, down past the valve
and valve seat and through the trap.
The india rubber ring has an internal flange which fits a corresponding groove
around the end of the plug; the ring is also secured in its place by a collar
screwed on to the plug; the collar is cylindrical on the exterior and it works
loosely in a circular opening in the centre of the grating. The tubular plug serves
also as the overflow from the bath, its upper end being at a suitable level and
being left open or the plug may be solid and an ordinary overflow be taken from
the back of the bath. A hook connects the plug with a pull handle and by
this the plug can be lifted a suitable distance when it is desired to empty the bath.
The plug occupies a recess at the end of the bath and as will be seen it can be
readily removed for cleaning; the grating also can be removed giving access to
the trap beneath.
I arrange for the outlet of water from a lavatory basin in a very similar manner,
but in this case the valve seat and outlet passage may be formed in a piece with
the grating. The part fits an opening in the bottom of the basin and is inserted
from within; it is secured in its place by a ring nut screwed upou the outlet from
beneath the basin.
Dated this 5th day of May 1896.

COMPLETE SPECIFICATION.
Improvements in Fittings for Baths and Lavatory Basins.
I, OSCAR ELPHICK, of Lambeth Sanitary Engineering Works, Lambeth in the
County of Surrey, 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 :-
Figure 1 is a vertical section of a bath outlet constructe.l according to this
invention

page_text: a is a grating formed in one piece with an outlet passage a¹ and valve seat a³
secured into an aperture in the bath bottom, by means of a flange a bolted between
flanges 6 on the bath b and c on the discharge pipe or trap c.
The grating a may
however be separate from the outlet passage and valve seat and be fixed to the
same by means of a bayonet joint, or otherwise so that it can readily be moved for
cleaning purposes.
A tubular plug d works through an opening in the centre of the grating a its
lower end is armed with a ring of india rubber e which abuts on the valve seating a
and serves as a valve. A short lift of this valve opens a wide passage by which
the waste water passes from the bath, flowing through the grating a down past the
valve and valve seat and through the discharge pipe or trap c.
The india rubber ring e has an internal flange el which fits a corresponding
groove around the end of the plug d, the ring is also secured in its place by a
metal collar d' screwed on to the plug, the collar is cylindrical on the exterior and
it works loosely in a circular opening in the centre of the grating a. The tubular
plug d serves also as the overflow from the bath, its upper end being at a suitable
level and being left open, or the plug may be solid and an ordinary overflow be
taken from the back of the bath. A hook f¹ connects the plug d with a pull
handle and by this the plug can be lifted a suitable distance when it is desired to
empty the bath. The plug d occupies a recess at the end of the bath, and as will
be seen it can readily be removed for cleaning. The grating a when separate and
fixed by a bayonet joint can also readily be removed thus giving easy access to the
discharge pipe or trap c.
Figure 2 is a horizontal section and Figure 3 a vertical section of the outlet
from a lavatory basin. In this case, the grating a in one piece with the outlet a¹
and valve seating a has a flange a³ which fits a rebate round an opening in the
bottom of the basin and is inserted from within the basin; it is secured in its place
by a fly nut g screwed upon the outlet from beneath the basin, and is connected to
a discharge pipe or trap by means of an ordinary screw coupling.
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. The combination of an annular grating, an outlet and valve seat below the
grating and a plug or valve rod passing through the central hole of the grating
substantially as described.
2. The combination of the plug, the flanged elastic ring and the collar
substantially as described.
3. Fittings substantially as described and shown in the drawings.
