I THOMAS SEAVILLE TRUSS of 17 Alkindon Road Chiswick in the County of
Middlesex Civil Engineer do hereby declare the nature of my Invention for
IMPROVEMENTS IN THE CONSTRUCTION OF STENCH TRAPS FOR SANITARY AND
OTHER PURPOSES, to be as follows:-
These Improvements consists in constructing a box with an outlet pipe at the
bottom and having an inlet pipe passing into the side and turning upwards within
the box and on this end of the inlet pipe a spindle valve acts which allows the
fluids to pass through such box but not to return so that such Stench Traps are
allways sealed without water These Improvements relate to the construction of
Stench Traps for Sanitary and other purposes whereby the foul air and other fluids
in the drains are prevented from ascending through such Traps.
The first part of my said Improvements consists in the construction of a box
with a removable cap fitted on the top and having an outlet pipe from the bottom
thereof and through the side of the box an inlet pipe is conducted the end thereof
that passes into the box being curved and rising towards the cap of the box and
terminating at a short distance therefrom and with the center of such inlet pipe in
the longitudinal centre line of the box and on this end of the inlet pipe and
covering the orifice thereof a disk, cone, or spherical faced valve with a spindle or
feathers to act as such attached thereto is fitted to act thereon the said valve being
kept in its working position by the spindle attached to it working in a socket
formed in the cap on the top of the box the other end of the inlet pipe that is
outside of the box being turned upwards to any required distance above the cap of
the box.
I have described the valve as having a spindle working in the cap of the box but
it may work in the end of the inlet pipe on which it acts.
The second part of my said Improvements consist in constructing the box of the
Traps with the inlet and outlet pipes in one piece when the same are made of cast
metals.
This is accomplished by making a complete pattern of the outer form of the Trap
with the inlet and outlet pipes attached and constructing the body core to form

page_text: the interior of the box and outlet pipe and the exterior and thickness of metal of
the inlet pipe within the box in two parts and the core for to form the interior
of the inlet pipe in one piece this core being inserted and fixed in one part of the
body core and held in the desired position by a print on the end thereof fitting into
the body core the other part of the body core is then fixed on the part containing
the end of the inlet pipe core and then a complete core is constructed that forms
the interior of the Trap with the inlet and outlet pipes in one piece.
As my said Improvements are capable of various modifications without departing
from the principle thereof I do not restrict myself to material or dimensions or to
the precise form or placement of the several parts thereof.

page_text: 1 THOMAS SEAVILLE TRUSS of No 17, Alkindon Road, Chiswick in the County
of Middlesex, Professor of Natural Philosophy, do hereby declare the nature of
my Invention for IMPROVEMENTS IN THE CONSTRUCTION OF STENCH TRAPS FOR
SANITARY AND OTHER PURPOSES, and in what manner the same is to be performed,'
to be particularly described and ascertained in and by the following statement :-
These improvements relate to the construction of Stench Traps, for Sanitary and
other purposes with spindle valves that form the seal for such Traps independent of
any liquid, and also prevent any fluid entering such Traps by their outlet pipes
from ascending through such traps; and the process of their manufacture.
The first part of my said improvements consists, of the construction of a circular
or other shaped box with a cap fitted on the top, and having an outlet pipe from
the bottom of such box, and through the side of this box an inlet pipe is inserted
having the end thereof that passos into the box curved and rising towards the cap
on the top of the box, and terminating at a short distance therefrom,, with the.
centre of this end of the inlet pipe in the longitudinal centre line of the box, and
on this end of the inlet pipe a disk, cone, or spherical valve is fitted to act, to cover
and close the same, and to this valve a spindle is attached which works in a socket
formed in the cap on the top of the box, whereby the valve only moves in line with
the longitudinal centre line of the box to open or close this end of the inlet pipe ;
the other end of this inlet pipe that is outside of the box, is turned upwards to any
required distance above the cap on the top of the box.
By these arrangements, any fluids entering the inlet pipe lifts the valve that is
on the end thereof within the box to pass through such Traps, after which the
valve by its gravity falls to its seat again covering and closing the orifice of this
end of the inlet pipe, thereby preventing any fluids that may rise in the outlet pipe
from passing and ascending through the inlet pipe; the spindle of the valve that
works in the socket formed in the cap of the box, determines that such valve shall
only move in the longitudinal centre line of the end of the inlet pipe on which it
acts, whereby its certain action is secured; whilst the pressure of any fluids from
the direction of the outlet pipe acts on the top of the valve to keep it tight to its
seat on the end of the inlet pipe.
The second part of my said improvements consists, of constructing the box of the
trap with the inlet and outlet pipes in one piece when the same are made of cast
metals, this is accomplished by making a complete pattern of the outer form of the
Trap with the inlet and outlet pipes attached, and constructing the body core to
form the interior of the box and outlet pipe and the exterior of the inlet pipe
within the box in two parts, and the core to form the interior of the inlet pipe in
one piece, the inlet pipe core is inserted and fixed in one part of the body core, and
held in the desired position by a print or projection on the end thereof fitting into
one end of the body core, the other part of the body core is then fixed on the part
of the body core containing the inlet pipe core, and then a complete core is
constructed that forms the interior of the trap with the inlet and outlet pipes in
one piece.
In order that the nature of my said improvements, and in what manner the same
are to be performed may be more fully understood, I will proceed to describe the
several Figures on the sheet of Drawing hereunto annexed, all of which Figures are
marked with the like letters of reference to the like parts throughout,
Figure 1, is a longitudinal section of a Stench Trap constructed according to the
first part of my said improvements, in which a, is the box; and b, is the outlet

page_text: pipe; and c, is the cap on the top of the box a,; and d, is the socket formed in such
cap for the spindle e, attached to the valve f, to work in; and g, is the end of the
inlet pipe h, that is within the box a, on which end of such inlet pipe the valve f,
acts; and i, is the end of the inlet pipe h, that is outside of the box a,. Figures 2,
and 3, are longitudinal sections of the two parts of the body core for forming the
interior of the box and outlet pipe and the exterior of the inlet pipe that is within
the box; and Figure 4, is a longitudinal plan of the core for forming the interior of
the inlet pipe, in which Figures; k, is one half of such body core; and 7, is the
other half of the same; and m, is the recess therein for the print n, on the end of
the inlet pipe core o, to rest in; and r, r, is the space in the parts of the body
core k, and 7, that forms the end g, of the inlet pipe h, that is within the box a..
I have described the valve having the spindle attatched to it working in a socket
formed in the cap on the top of the box, but such spindle may also work in the end
of the inlet pipe on which it acts, and such spindle may be solid, hollow, or fluted.
The several parts of my said improvements are held together by screws, screw
bolts, or any of the usual contrivances for such purposes.
As my said improvements are capable of various modifications without departing
from the principle thereof, I do not restrict myself to material, dimensions, or the
precise form or placement of the several parts thereof.
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 The construction of Stench Traps with spindle valves that form the seal for
such Traps independent of any liquid, as herein before described.
2nd The constructing of the bodies of such Traps and their outlet and inlet pipes
in one piece when made of cast metals, in manner as herein before described.
