Improvements in Trough Water closets
I, JAMES RIMMER, of 14, Trentham Street, Runcorn, Cheshire, Architect and
Surveyor, do hereby declare the nature of this invention to be as follows
This invention relates to improvements in the construction of trough water-
closets, flushed periodically, and usually by waste-water from the slop-stones or
wash-houses of dwelling houses, rain-water, and other waste-water
such waste-
water being collected in a tipping basın disposed between the closet and the
dwelling house, so that a considerable volume of water is discharged periodically
into the trough of the closet and thence to the main sewer
The trough of a closet constructed according to this invention forms the bottom
I he waste-water pipe
of the pit or well of a brick or similarly built water-closet
discharges itself into one end of the trough, the other end of the trough open ng
into a specially formed open-mouthed trapped outlet-pipe At the junction of the
trough-end and outlet-pipe a horizontal weir or sill is formed which insures that a
certain depth of water will remain in the trough after each flush out
The trough and trapped outlet-pipe may be separate parts or made in one piece,
and the material employed in their manufacture may be glazed fire-clay, enamelled
ironwork or other suitable material

I, JAMES RIMMER, of 14, Trentham Street, Runcorn, Cheshire, Architect and
Surveyor, 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
-
This invention relates to improvements in the construction of trough water-
closets, flushed periodically, and usually by waste-water from the slop-stones or
wash houses of dwelling houses, rain water, and other waste-water, such waste-
water being collected in a tipping-basın disposed between the closet and the
dwelling house, so that a considerable volume of water is discharged periodically
into the trough of the closet and thence to the main sewer
The trough of a closet constructed according to this invention forms the bottom
The waste-water pipe
of the pit or well of a brick or similarly built water-closet
discharges itself into one end of the trough, the other end of the trough opening
into a specially formed open-mouthed trapped outlet-pipe At the junction of the
trough-end and outlet-pipe a horizontal weir or sill is formed, which insures that a
certain depth of water will remain in the trough after each flush-out

page_text: In the drawing hereto annexed
Figure 1 is an elevation of the mouth of the trapped outlet
Figure 2 is a cross-section and Figure 3 is a plan of the trough and
Figure 4 is a longitudinal section of a trough and trapped outlet formed according
to this invention
A represents the pit or well of a trough closet a is the trough, forming the
bottom of the pit A, and is entirely open for inspection and brushing out when
necessary b is the trapped outlet of the tough, such outlet being formed with a
horizontal weir or sill c at its mouth, and is provided with a ventilation pipe and
inspection aperture d is the flushing water inlet The weir or sill e insures that
a certain depth of water, which may be four inches or thereabouts, remains in the
trough after each flush out, thus preventing excrement from adhering to the trough
The trough and trap may consist of separate parts as shewn in the drawing or
may be formed in one piece and the material employed in their construction is
preferably glazed file-clay or enamelled cast iron or the concrete bottom of the
closet-pit may form the trough and may be faced with cement
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is
1 The combination in a trough-closet of the type described of an open trough
forming the bottom of the pit of such closet with an open-mouthed trapped outlet-pipe
provided with a horizontal weir or sill arranged at such a height above the bottom
of the trough that a certain depth of water is ictained in such trough after each
flush, substantially as described
2 An open-mouthed trapped outlet for trough-closets provided with a horizontal
weir or ill for the purpose of retaining a certain depth of water in the trough
after each flush, substantially as described
