WILLIAM MORGAN-BROWN, of the Firm of Brandon and Morgan-Brown, Engineers
and Patent Agents, of 38, Southampton Buildings, London, and 1, Rue Laffitte,
Paris. "IMPROVEMENTS IN WASH BASINS, URINALS, SINKS, AND OTHER SIMILAR
ARTICLES."
This Invention of improvements in wash basins, urinals, sinks, and other similar
articles, consists in a urinal basin and combining a bell trap so that said trap can be
lifted out through the bottom of the urinal without disconnecting the other fittings,
in combining an overflow pipe, also in combining a water supply pipe and to let
the water cover that part of the inner surface of the basin which by its slight
inclination would retard the flow of the urine and favor the formation of sediment,
and so avoid having a dried bottom in the pan.
The basin is made of angular or flat sides with or without a wall shield, the
lower part and below the basin having a cylindrical bell trap chamber and an over-
flow pipe opening into a space surrounding the bell trap chamber; the outer
chamber has a flange and pipe tight for the connection with the outlet, and an
upper extension of the outlet rises up within the chamber for exit of the contents,
and is arranged at such height as to keep the bottom covered. The outlet pipe
may be screwed for the waste pipe or otherwise fitted to it. A bell with openings
round its base and with steadying arms, flanges, or fins bearing on the outlet tube,
the upper part of the bell has a conical flange which rests on the bottom of the
basin, the flange being perforated as desired; if these holes became obstructed the
.

page_text: water enters the overflow; the bottom rim of the bell rests on the flange and is per-
forated or notched to allow the water to enter by these apertures to rise within the
bell and escape by the upper orifice of the outlet pipe.
In the construction of the wash basins an extension is made below the proper
bottom so as to form a sufficiently capacious chamber to hold the bell trap and leave
a space all round it for the trap chamber; the outlet pipe is tapped at its bottom
part for a screw, and on the rising part of the outlet pipe a flange is formed to fit a
recess in the bottom of the basin; a nut on the outside of the pipe and suitable
packing completes the junction. An overflow recess is fitted to the basin and
enters the escape chamber; the false bottom or apparent bottom of the basin is fitted
with a plug in the usual manner which is lifted to allow the contents to escape;
when this plug is removed the whole of the bell trap and chamber which is similar
to the urinal trap described can be removed and cleansed with the greatest facility.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Morgan-Brown in the Great Seal Patent Office on the 13th
June 1877.
WILLIAM MORGAN-BROWN, of the Firm of Brandon and Morgan-Brown, Engineers
and Patent Agents, of 38, Southampton Buildings, London, and 1, Rue Laffitte,
Paris, "IMPROVEMENTS IN WASH BASINS, URINALS, SINKS, AND OTHER SIMILAR
ARTICLES." (A communication from abroad by Andrew Gormly Myers, of 94,

This Invention consists,―
Firstly. In a wash basin constructed with an extension below its proper bottom
for the purpose of forming a bell trap chamber, said basin and chamber being in
communication with another by means of a removeable section of the bottom of the
basin, which section when removed admits of access to the chamber, and the
removal of the bell cover up through the basin, and thus the trap chamber can be
cleaned out without the necessity of disconnecting any other parts.
Second. Combination with basin of a bell trap chamber by means of an overflow
pipe which discharges first into the bell trap chamber.
Third. In a coupling collar formed on the waste pipe of the bell trap in combi-
nation with the bell cover trap chamber and the basin.
Referring to the Drawings, A is the basin, which has near its top rim a number
of openings a, whereby the overflowing of the basin is prevented. The overflow
water passing through said holes a is conducted by a closed passage B which is
fastened to the sides of the basin through an opening b into a chamber C below the
basin. The chamber C is fastened to the bottom of the basin A, and is then closed
by a plug or lid c, which lid is removed when the water is to be drawn off the basin.
The bottom of the chamber C is clamped between the middle flange d of the
waste coupling D and a leather washer cand nut E on the lower part of said
coupling which is for that purpose provided with a screw thread d. Above the
flange the coupling D extends upwards in shape of a tube D¹ which is covered by
a bell F. This bell F is held concentric with the tube D¹ by means of radial
arms, the rounded ends of which bear upon the tube D¹; the water in chamber C
passes into the bell F through passages f¹in the base of said bell

page_text: of the basin, whereby the water is caused to enter the chamber C, the bell F
through the openings fl, and finally the waste pipe through the couplings D.
The described construction has the advantages, that the basin, the overflow pipe
and the bell trap may be removed in a body by the simple manipulation of un-
Screwing the plug D, having the waste pipe intact. Another advantage is, that by
removing the lid c, the chamber C, the bell trap therein, and the mouth b of the
overflow pipe B are fully exposed, and on account of their easy accessibility may be
effectually cleaned out or repaired. The present construction of the basin A with
an S shaped trap in the waste pipe and the overflow pipe attached to the waste
pipe has no such facilities for access and for cleaning of its parts. The very shape
of the trap is the most disadvantageous for the purpose of cleaning, even by the
use of instruments, the cleaning by hand being impossible in most cases.
As the waste pipes are generally covered by partition walls or flues, repairs on
such trap are annoying and expensive, because they necessitate a great amount of
tinio, and the defacing or mutilation of parts of the building.
In its application to a urinal basin the Invention consists in,―
First. The combination of a bell trap with a urinal basin so that said trap can be
lifted out through the bottom of the urinal when required without disconnecting any
of the fixtures of the urinal.
Second. The combination of urinal or water closet bell trap and overflow pipe.
Third. The combination of an urinal basin, a bell trap, and a water pipe con-
nection which forms part of the trap.
The object of the Invention is to avoid having a dry bottom in a urinal basin,
and to let the water cover that part of the urine surface of the basin which by its
slight inclination would retard the flow of the urine and favor the forination of
sediment, also to provide a urinal trap which is of easy access and which may be
conveniently cleaned out or repaired without disturbing the waste pipe.
Referring to the Drawings, A. is the basin; B, the wall shield; E, a cylindrical bell
trap chamber below the basin; D, overflow pipe opening into the chamber C; the
bottom c of C is formed by a flange of the water joint E, and is soldered or other-
wise fastened to the metal of said chamber; an upper tubular extension E¹ of
joint E serves as an exit for the water and urine, and by its height keeps the
surface of the water in the basin at such elevation that the bottom and shallowed
sides are covered and washed by it. The joint E is provided with a screw thread e
whereby it is fastened to the wasto pipe. A bell F with openings around its base
and with steadying or centering arms f¹ bearing on the tubes E' is inserted into
the chamber C in the manner shown. The upper part of the bell F has a conical
rim G which rests upon the bottom of the basin, and which is provided with a
number of holes g through which the water passes into chamber C. If the holes g
should become obstructed the water would rise and finally enter overflow pipe D by
ineans of opening d in shield B. From pipe D the water enters chamber C through
opening d, and enters bell F through openings f, the same as the water which enters
through holes From the bell the water is drawn off by the tubular extension E'
of the joint E and delivered to the waste pipe. This bell trap has the advantage
over the cominon S shaped trap in that it is within easy reach for cleaning or
repairing purposes, and that access to the lower part of the overflow may be had at
the same time. The main difliculty in the operation of the S shaped trap is this,
that they in most cases act as syphons and empty the trap, thereby frustrating its
purposes. This difficulty is overcome by this bell trap, because the amount of water
within the bell can only be withdrawn by syphonic action to a very slight degree,
whereupon the entrance of air into the bell counteracts the said action at once. By
preventing the free entrance of the water into chamber C by means of the perforated
rim G, I divide the flow of water into a number of currents, and thereby increase
the cleaning effect of the water in the basin while passing off, causing it to
constantly wash the sides and bottom of the basin, and prevent the formation and
fastening of sediment on the sides and bottom thereof.
Having now described and particularly set forth the nature of the said Invention,

page_text: and the manner of carrying the same into effect, I would have it understood that
what I claim is,―
First. A wash basin constructed with the bell trap chamber C, and with a
removeable bottom section c, substantially as and for the purposes set forth.
Second. The combination of the wash basin A, bell trap chamber C, and overflow
passage B, substantially as and for the purposes set forth.
Third. The combination of coupling collar D, waste pipe D¹, removeable bell

herein set forth.
Fourth. A urinal basin having a bell trap attached to its bottom so that the bell
cover thereof may be lifted out through the bottom of the urinal without discon-
necting any of the fixtures of the urinal, substantially as and for the purposes set
forth.
Fifth. A urinal basin A in combination with the joint connection E, having
flanges c and a tubular exit E, a chamber C and bell F, having base openings fand
a perforated rin G, substantially as and for the purposes described.
Sixth. A urinal basin A in combination with a bell trap C, E, F, and the over-
flow pipe D, substantially as and for the purposes set forth.
