Improvements in or connected with Sink, Bath, and like Waste
Fittings.
I, THOMAS WILLIAM ROGERS, of No. 27 & 28, The Triangle, Bournemouth, in
the County of Hants, Ironmonger, do hereby declare the nature of this inven-
tion to be as follows:-
-
";
My invention relates to improvements in what are known as waste fittings,"
namely the metal fitting which forms the connection between, for instance, the
bottom of an earthenware sink and its waste or discharge pipe, and has mainly
for its object to provide a quick discharge for the water or other liquid and
enable it to have a strong flush from the sink pan to the discharge pipe so as
to pass full bore therethrough.
According to my invention I construct "waste fittings" for sinks, baths,
and like purposes with the entrance or mouth of the fitting of greater area than
the waste or discharge pipe and with the area of the grating orifices equal or
more than equal to the area of the waste or discharge pipe. I also provide for
the grating being flush or even with the surface of the sink or other vessel.
I close the grating orifices by means of a flush cover instead of an inserted
of an inserted plug, and I form the male portion of the joint of the union on
the upper part of the fitting, and the female portion on the "lining" of the
union so as to provide a safe joint.
I will as an example describe my invention as applied to the waste fitting of
a kitchen sink vessel, I form the upper portion of the fitting in the form of a
tapered cup having its mouth of greater area than its discharge so as to allow
for a grating in which the collective orifices are of area equal to or greater than
the area of the discharge pipe. The cup has a flange on the top which fits into
a counter-sink on the surface of the vessel, the body of the cup is of depth to
suit the thickness of the sink bottom and fits in a tapered hole therein, and is
secured by a back nut connection, a continuation of the cup, of internal diameter
slightly larger than the waste pipe and having its orifice equal to the diameter
of the waste pipe forms the upper and male part of the union which fits into the
female part which I form on the lining which is secured by the usual union nut
and to which the waste pipe is attached.
The grating is made to fit in a recess in the top part of the fitting, flush with
the surface, and is of size so that the collective area of its orifices equal or are
greater than the area of the waste pipe. The cover for the grating is a disc of
metal having a surface of india-rubber or equivalent material and provided with
a pin or pins on its underside which fits or drops into a hole or holes in the
grating, and a ring on its upperside by which it may be removed.

COMPLETE SPECIFICATION.
Improvements in or connected with Sink, Bath, and like Waste.
Fittings.
I, THOMAS WILLIAM ROGERS, of No. 27 & 28, The Triangle, Bournemouth, in
the County of Hants, Ironmonger, do hereby declare the nature of my said inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
My invention relates to improvements in what are known as waste fittings,
namely the metal fitting which forms the connection between, for instance, the
bottom of an erthenware sink and its waste or discharge pipe, and has mainly
for its object to provide a quick discharge for the water or other liquid and
enable it to have a strong flush from the sink pan to the discharge pipe so as
to pass full bore therethrough.
"
According to my invention I construct waste fittings" for sinks baths
and like purposes with the entrance or mouth of the fitting of greater area than
the waste or discharge pipe and with the area of the grating orifices equal or
more than equal to the area of the waste or discharge pipe. I also provide for
the grating being flush or even with the surface of the sink or other vessel.
I close the grating orifices by means of a flush cover instead of an inserted
plug, and I form the male portion of the joint of the union on the upper part
of the fitting, and the female portion on the lining of the union so as to provide
a safe joint.
I will as an example describe my invention as applied to the waste fitting of
a kitchen sink vessel, I form the upper portion of the fitting in the form of a
tapered cup having its mouth of greater area than its discharge so as to allow
for a grating in which the collective orifices are of area equal to or greater than
the area of the discharge pipe. The cup has a flange on the top which fits into
a counter-sink on the surface of the vessel, the body of the cup is of depth to
suit the thickness of the sink bottom and fits in a tapered hole therein, and is
secured by a back nut connection, a continuation of the cup of internal diameter
slightly larger than the waste pipe and having its orifice equal to the diameter
of the waste pipe forms the upper and male part of the union which fits into the
female part which I form on the lining which is secured by the usual union nut
and to which the waste pipe is attached.
The grating is made to fit in a recess in the top part of the fitting, flush with
the surface, and is of size so that the collective area of its orifices equal or are
greater than the area of the waste pipe. The cover for the grating is a disc of
metal having a surface of india-rubber or equivalent material and provided with

page_text: a pin or pins on its underside which fits or drops into a hole or holes in the
grating, and a ring on its upper side by which it may be removed.
By constructing a sink waste fitting as above described and according to my
invention the risk of stoppage is prevented and the sink trap is fully flushed
each time the sink is emptied.
Having thus generally described the object, nature and effects of my invention
I will now proceed to describe it with reference to the accompanying sheet of
drawings. The example of apparatus which I have illustrated is an arrangement
and construction of parts according to this invention applied to a kitchen sink
vessel. In the various figures of the drawings the same parts are designated
by the same letters and they correspond with those used in the following expla-
nation of the example.
Figure 1 is a vertical rectional elevation of a sink waste fitting according to
my invention.
Figure 2 is a plan of the waste fitting with the cover removed, showing the
grating.
Figure 3 is an outside elevation of the waste fitting.
Figure 4 is a plan of the waste fitting with the cover on.
Figure 5 shows a modification of the union joint between the waste fitting and
the discharge pipe.
With reference to the drawings a designates the cup or mouthpiece of the
waste fitting and b denotes the metal of the sink bottom I form the mouth c of
the cup of greater area than the discharge d and fit the cup flush into the
nietal of the sink where it is secured by the flange e, and the screw nut g
which screws on the discharge pipe d under neath the sink metal, h denotes the
grating the collective holes or orifices, of which I form of an area equal to or
greater than the area of the discharge pipe d, this grating if made to fit in a
recess in the top part or mouth c of the fitting flush with the surface, i denotes
the cover of the fitting, this consists of a disc of metal, having a surface or ring k
of india .rubber or equivalent material to make joint with with the surface of
the fitting, and provided with a pin m on its underside which takes into a hole
in the centre of of the grating h and a ring n on its upper side by which it may
be removed.
The discharge pipe d is of internal diameter slightly larger than the waste
pipe but has its mouth d equal to the diameter of the waste pipe and forms the
upper and male part of the union which fits into the female part or lining which
is designated by this lining p is secured to the part d d by the usual union
nuts to which the waste pipe is soldered.
Instead of attaching the waste pipe to the part dd by soldiering to the lining p
the lining may be dispenced with, and the lead waste pipe t may be flared out
at its mouth and secured direct to the part by the nuts as shown in
Figure 5.
I would have it understood that although I have shown my improved waste
fitting as applied to a sink waste it is equally applicable to baths, lavotory
basins, and other waste fittings in which a flush through the grating equal to
the full bore of the waste pipe is desired.
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-A waste fitting for sinks, baths, and the like, constructed and operating
substantially as described, that is to say a waste fitting having a cupped entrance
of greater area than the discharge pipe and provided with a grating in which
the orifices are collectively of equal or greater area than the discharge pipe so
that when discharging the waste liquid from the vessel it is discharged full bore
through the waste pipe as set forth.

adapted, to operate substantially as described, and illustrated in the accompanying
drawings.
