PROVISIONAL SPECIFICATION.
Improvements in Sanitary Apparatus, applicable to Water Closets,
Traps, and Sinks.
I, THOMAS URE, of 164 Henderson Street, Glasgow, in the County of Lanark,
North Britain, Plumber, do hereby declare the nature of this invention to be as
follows:-
This invention relates to sanitary apparatus wherein is used a water-seal or trap
to prevent the escape of foul air or gas from the drain or sewer, and is applicable
to water-closets, sewer, drain, or soil pipe traps and sinks; the main object
being to simplify the construction of such apparatus and render them casily taken
apart for renewal or cleansing without disconnecting the inlet or outlet pipes
thereto.
The apparatus consists mainly of two parts viz. the shell or outer case, and the
trap inside thereof; the shell being formed to suit the purpose for which it is
intended.
As adapted for a water closet, the shell or outer case may be formed round or
oval in plan, the top constituting or bearing the seat, and the bottom being con-
nected to the outlet pipe to drain or sewer. Towards the top of the shell is formed
round its inside, a ring or flange on which is seated the trap part. The top of
trap consists of a disc or shell of same shape in plan as the inside of outer case at
ring, so as to fit tight thereon; an india rubber ring, putty or other suitable
stuffing being interposed to make a watertight joint between joints of case and
trap; or the trap and case may be formed in one. The trap has an orifice on
top which opens into a deep pocket or recess, round at bottom, and across which is
formed a partition, only open at bottom, thus forming the syphon or trap, the
outlet being on one side, over which may, or not, be fitted a flap or other valve.
The shell is formed at level of top of trap, with a water inlet or horn, opening
tangentially or otherwise on top of trap, so that the flushing water shall whirl
round or over top of trap. In some cases a rib or breakwater projects up from
trap.
As adapted to a drain or sewer-gas trap the apparatus is almost similar to above,
the inlet to trap from drain or elsewhere, taking the place of that of the flushing
water-inlet; the trap being ventilated by top if desired.
As applied to sinks, the sink may be made with an orifice in bottom into which
is fitted the shell of trap, the top of shell being about level with bottom of sink,
and the orifice of trap may have a grating over it.

COMPLETE SPECIFICATION.
Improvements in Sanitary Apparatus, applicable to Water Closets,
Traps, and Sinks.
I THOMAS URE of 164 Henderson Street, Glasgow in the County of Lanark,
North Britain, Plumber, 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:-
My said invention relates to sanitary apparatus wherein is used a water seal or
trap to prevent the escape of foul air or gas from the drain or sewer and is

page_text: applicable to water closets, sewer; drain or soil pipe traps and sinks etc., the object
mainly being to simplify the construction of such apparatus, and render them easily
taken apart for renewal or cleansing, without disconnecting the inlet or outlet
pipes thereto; and which causes syphonic action in such apparatus to be practically
impossible.
On the annexed drawings
Figs: 1 and 2 are respectively a sectional elevation and plan, and Fig. 3 a section
of the trap thereof at right angles to Fig. 1 on the liner, of an apparatus adapted
as a water closet.
Figs. 4 and 5 are sectional elevations of apparatus as adapted for ventilating
and sink traps.
The apparatus consists mainly of two parts riz.: the shell or outer case A and
the trap inside thereof either or both of which said parts may be made of
earthenware, métal or other suitable material, the shell A being formed to suit
the purpose for which it is intended.
Referring to Figs. 1. 2 and 3 of the drawings, as adapted for a water closet
the shell or outer case A may be formed round, oval, oblong, or otherwise in
plan, the top of said shell constituting or bearing the seat and the bottom being
provided with an outlet branch c which may be on bottom or side for connecting
to the outlet pipe to drain or sewer. Towards the top of the shell is formed
round its inside a ring or flange d on which is seated the trap part B. The top
of trap B in the water closets consists of a disc or shell of same shape in plan
as the inside of outer case A at ring d so as to fit tight thereon, an india-rubber
ring, putty or other suitable stuffing being interposed in the groove f to make a
watertight joint between joints of case A and trap B. The top of trap e may be
formed as shown so that water may lie thereon, or otherwise, it may be formed
inclined inwards as shown at Fig. 4. The case and trap may obviously be formed-
in' one.
The trap B has an orifice g on top which opens into a deep pocket or
recess round at bottom and across which is formed a partition only open at
bottom, thus forming the syphon or trap; the outlet being on one side, over
which, or not, may be fitted a flap valve K: The shell is formed at level of top of
trap with a water inlet or horn in any position round case A, and to suit fitting
the inlet pipe thereinto either vertically, horizontally or otherwise, and said inlet
opening tangentially (as shown at Fig. 2) on top of trap so that the flushing water
from ordinary cistern or waste-water preventor in ordinary way shall whirl round
or over top of trap and then down the centre thereof. In some cases a rib or
breakwater m either radially or curved as shown at m¹ may project up from top
of trap so as to divert the soil into the centre of trap down which, it and the
flushing water flows and escapes therefrom through the trap outlet ; into case A
and thence to sewer; the trap being sealed by water left lying in trap below level
of trap outlet j.
The apparatus as adapted for a ventilating or manhole drain or sewer-gas trap
is represented at Fig. 4 and is somewhat similar to the foregoing consisting of a
shell A and trap B. The shell is provided with inlet branch of which there may
be several round case for connecting to one or more drains, and an outlet branch c
at bottom for connecting to main drain or sewer. The trap is ventilated at top
through a removable grating n which may be of any size, and at any level from
drains; or said grating may be replaced by a closed cover and the trap have a
branch for connecting to a ventilating shaft. Otherwise the case A may be
made of a bottom and top part so that the top part may be varied with number-and
position of inlet and outlet branches o so as to suit different circumstances, the
lower part of case A. and trap B still remaining the same. Under this modification
the bottom part could be set in position first and the top part set on same to suit
connections etc. and then hermetically jointed to bottom part. The top e of the
trap may be level or slope downwards towards opening 9, otherwise the apparatus
is or may be similar to the modification before described:
As adapted as shewn at Fig. 5 for sinks etc. the sink may be made with an orifice

page_text: in bottom having a ledge p round same into which fits the shell A of trap. The
top of shell may be at or about level with bottom of sink and fitted with a grating
over it. The trap B may be set in said case A at any convenient level from
bottom of sink and is otherwise similar to those hereinbefore described.
shell A in this case has no inlet branch, but has an outlet branch c at bottom
shown fitted in a pipe u leading to drain.
The
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.
1st. Apparatus applicable as water closets, ventilating or other traps, com-
prising an outer cylindrical, oval or oblong in plan case A, having outlet c at
bottom or side, and one or more inlets l, and with or without a ventilating branch o,
in combination with a water trap B with or without flap valve k, all arranged,
constructed and combined as set forth and shown.
2nd. In such apparatus the combination with the outer case A, of a removable
trap B, substantially as described and shown.
3rd. The arrangement and construction of parts of apparatus as described and
shown at Fig. 5.
