PROVISIONAL SPECIFICATION
Improvements in Waste Traps for Sinks, Slopstones, and similar
Conveniences.
I RALPH ASHTON of 14 Market Place, Manchester in the County of Lancaster,
Manufacturing Chemist do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to prevent the accumulation of refuse and solid
matter on the grids of waste pipes connected with sinks, or slopstones, and similar
conveniences, and to provide a neat and ready means of removing the refuse and
solid matter intercepted.
I accomplish my object by making a flanged cup of metal, earthenware, or other
suitable material, with an aperture in the bottom, or with an aperture and a
projecting nozzle. Inside this outer cup I place another flanged cup, perforated in
the sides and bottom, in such a way that a clear space is left between the two cups,
except at the rims where the inner cup rests on a ledge or ridge on the inside of
the outer one, the edges of both cups being flush with each other. The inner cup
is provided with a handle, bar, or projection by means of which it may be removed
when desired. The outer cup may be let into and fixed to the floor of the sink,
slopstone, or similar convenience by making a hole through the floor with a
recessed ledge for the flange of the cup to rest upon, the rim of the cup being
flush with or slightly below the surface of the floor-and it may be joined to the
waste pipe by bringing the end of the waste pipe through the aperture at the
bottom of the cup and fixing the grid over the mouth of the pipe, or the grid may
be fixed over the aperture, and the nozzle at the bottom of the cup let into the
end of the pipe and joined to it. The outer cup having been put in position and
attached, the movable perforated one is then placed inside it.
By this arrangement the waste water or slops run freely into the perforated cup
where the refuse and solid matter are intercepted and collected, the waste liquor
passing through the perforations into the outside cup and thence through the grid
into the waste pipe. The perforated cup, being movable, can be lifted out and the
drained refuse and solid matter thus easily removed.
Instead of making an outer cup as described, the end of the waste pipe may be
widened sufficiently to serve the same purpose, or, if the floor of the sink, slop-
stone or similar convenience is of sufficient thickness a cavity may be made in it to
serve the purpose of the outer cup.

Improvements in Waste Traps for Sinks, Slopstones, and similar
Conveniences.
I, RALPH ASHTON of 14 Market Place, Manchester, in the County of Lancaster,
Manufacturing Chemist, do hereby declare the nature of this invention and in
what mauner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The object of my invention is to prevent the accumulation of refuse and solid
matter on the grids of waste pipes connected with sinks, or slopstones, and similar
conveniences; and to provide a neat and ready means of removing the refuse and
solid matter intercented.

page_text: In order that my said invention, and the manner of performing and carrying
the same into effect or practice may be properly understood, I have hereunto
appended an explanatory sheet of drawings, in which the same reference letters
are used to indicate corresponding parts in all the figures where shown.
1 accomplish my object by making a flanged cup, or socket, Fig. 1, of metal,
earthenware, enamelledware, or other suitable material, with an aperture, B, in the
bottom, or with an aperture and a projecting nozzle, C, the flange being counter-
sunk, A.
Inside this outer-cup, which I call the socket, a louse flanged cup, Fig. 3, is
placed with its flange resting in the countersink of the socket flange, the upper
surfaces of both flanges being flush with each other, L. The loose cup is made
of brass, enamelledware, or other suitable material, and is perforated in the sides
and bottom, or by preference in the sides only. It is provided with a handle, or
small projection, M, from the rim by means of which it can be moved. Instead of
a flange the cup may have small arius or nipples projecting from the rim to hold it
in its position in the socket, but a flange is preferred.
The design of the perforations shown in the accompanying drawings, F Fig. 3,
is the one preferred, but other suitable ones may be used.
When the cup is in
position in the socket, there is a clear space left around and below it as shown at N
Fig. 7. The drawing Fig. 7 shows a part of the socket cut away, in order to
display the internal relative position of the socket and cup, when the latter is in
position.
If the socket is made of a soft metal such as lead, a countersunk flange, E Fig. 2,
of a harder metal such as brass, is fitted on the top of it to preserve more effectually
its shape. The countersink in which the flange of the loose cup rests in the socket
is in some cases, as shown by Fig. 4 at A', made sufficiently deep to admit of a
plug, G, being inserted above the cup, this arrangement permitting of the sink or
similar convenience to which the socket is attached, being used to hold water or
other liquids.
The perforated cup by preference made conical, but both the cup and the
socket may be oblong, square, or other shape to meet special requirements.
For ordinary purposes the following dimensions of the various parts of the
perforated cup and the socket are suitable, but they may be varied:-The socket-
length from the flange to the end of the nozzle 5 inches diameter across the
flange 34 inches: depth of the chamber 24 inches: diameter of chamber 28 inches:
length of nozzle 27 inches bore of nozzle 14 in. depth of countersink in flange
1 inch, and inch when the countersink is intended to admit of a plug. The
perforated cup diameter across the flange 3 inches: width of flange inch:
depth of cup 1 inches diameter of the bottom 13 inches width of perforations
at the rim inch, and at the bottom 3 inch number of perforations 17 or 18.
These dimensions leave ample space around and below the cup, N Fig. 7, when
in position in the socket, for the cutflow of waste water, or other liquid from the
cup
:
The socket is readily connected to the waste pipe and fixed in position by placing
it in the countersunk hole, usually provided in the floor of the sink, slopstone, or
similar convenience, with its flange resting in the countersink, and then joining its
nozzle to the waste pipe. The point of the socket nozzle may have a small ridge,
or flange, as shown at H Fig. 6 in the drawings, above which the end of the waste
pipe, K, may be knocked against the nozzle, to increase the strength of the joint.
And in some cases the outside of the nozzle may be tinned, to facilitate its junction
with the waste pipe. When the socket is not provided with a nozzle, the end of
the waste pipe may be passed through the aperture in the bottom, and joined to
the socket inside the chamber, D.
After the junction of the waste pipe and socket has been made, an ordinary
sink grid may be placed over the aperture, at the bottom of the socket.
Instead of making an outer-cup, or socket, as described, the end of the waste
pipe may be widened sufficiently and adapted to serve the same purpose; or, if the

page_text: floor, J Fig. 5, of the sink, slopstone, or similar convenience is of sufficient thick-
ness, a cavity or chamber, D, may be made in it, with the countersink A or A' at
the top, and the aperture B at the bottom, as shown by Fig. 5 in the drawings, tu
serve the pose if the socket hereinbefore described. When the socket is formed
in the floor of the sink, slopstone, or similar convenience, as just described, the
waste pipe end may be passed into the aperture, B Fig. 5, and cemented or other-
wise secured to the bottom of the chamber, D' Fig. 5.
The action of the combination of the loo-e perforated cup and socket, with the
waste pipe and the floor of a sink, slopstone, or similar convenience is :-The
waste water, slops, or other liquids pass into the perforated cup, where the refuse
and solid matter are intercepted and collected, the waste liquor passing through the
perforations into the chamber of the socket, and thence through the grid into the
waste pipe. The perforated cup, being loose, affording a convenient means of
removing the refuse, as it may be lifted out of the socket and the refuse matter
thrown out.
The nature and novelty of my improvements cousist in fixing and applying to
sinks, slopstones, and similar conveniences the apparatus I have herein described,
consisting of a loose perforated cup and a socket for its reception, the socket being
in some cases formed in the floor of the sink, slopstone, or similar convenience; the
perforated cup being so adjusted in the socket as to sift the refuse and solid matter,
whilst at the same time allowing the waste water, or other liquid, to pass freely
into the waste pipe to which the socket is attached; the cup being also loose
permitting of its being taken out of the socket in order to throw out its contents,
thus affording a ready and neat method of disposing of the sifted refuse, without
resorting to the disagreeable operation of removing it from the grid with the
fingers, or the troublesome method of brushing it aside, which forms the essential
feature purpose and advantage of my invention.
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 is :-
:-
1. The fixing and applying to sinks, slopstones, and similar conveniences, the
combination of a loose perforated cup with a socket, all substantially as and for the
purposes herein described.
2. The loose perforated cup, Fig. 3, all substantially as and for the purposes
hereinbefore described in reference to and shown in the accompanying drawings.
3. The sockets, Figures 1, 2, and 4, all substantially as and for the purposes

4. The combination of a socket, loose perforated cup, and plug, Fig. 4, all
substantially as and for the purposes hereinbefore described in reference to and
shown in the accompanying drawings.
5. The combination of a loose perforated cup with a socket formed in the floor
of a sink, slopstone, or similar convenience, all substantially as and for the purposes
herein described.
6. The formation of a socket in the floor of a sink, slopstone, or similar con-
venience, suitable for the reception of a loose perforated cup, all substantially as
and for the purposes herein described.
