IMPROVE- MENTS IN STENCH OR DRAIN TRAPS
Year: 1884

page_text: I JOHN LEA CARTWRIGHT of Cony bere Street Birmingham in the County of
Warwick Machinist do hereby declare the nature of said invention for "IMPROVE-
MENTS IN STENCH OR DRAIN TRAPS" to be as follows:-
The principal object of my invention is to intercept and collect any dirt, sediment
or other solid matter carried by or held in suspension by the water or other liquids
passing through the drain or stench trap, to the sewer or other drain, and at the
same time the said trap acts as an effective seal against the egress or back passage
of sewer gases. The body of the trap is also more readily set by the confirmation
of its base.
Although I will only now describe my invention as applied to a stench trap, yet
my said invention is equally applicable to drain, gulley and other like traps soughs
and gratings.
The body or casing of the trap consists of a rectangular box open at top or at
its upper end, the base is made preferably flat, in order that the trap may be more
readily set or affixed in connecting it with a drain or other outlet.
The body of the trap when fixed is not liable to rock or move after having once
been set, in consequence of the confirmation of its base.
The outlet of the drain trap is situated on one of its sides, the outlet of which is
provided with the usual depending web or partition extending below the level of
the outlet passage for sealing the trap and within the rectangular box or casing
described I suspend or hang a loose sediment receptacle that is, a detachable
chamber tapering towards its bottom, which intercepts or collects any dirt or other
foreign matters held in suspension by the water passing through the trap-The
chamber is provided near its top with outlet water passages, which are somewhat
below the grating, covering the open top of the trap.
The dirt receptacle is provided with finger holes in its opposite sides for removing
it from the trap.
The working of the trap is as follows; water combined with dirt and other
matters pass through the grating of the trap falls into the suspended chamber or
CD

page_text: receptacle, the dirt held in suspension falls to the bottom of the chamber, while
the water alone passes off through the slits or openings near the top of the sides
thereof and falls into the body of the trap, and then passing away through the
sealed outlet as previously described-The dirt or other sediment thus intercepted
can be removed by withdrawing the suspended chamber and cleansed by turning
out the dirt, and then again replaced in position in the trap.

SPECIFICATION.
J, JOHN LEA CARTWRIGHT, of Conybere Street Birmingham in the County of
Warwick, Machinist, do hereby declare the nature of said invention for "IMPROVE-
MENTS IN STENCH OR DRAIN TRAPS," and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
The principal object of my invention is to intercept and collect any dirt, sediment
or other solid matter, carried by or held in suspension by the water or other liquids
passing through the drain or stench trap; to the sewer or other drain, and at the
same time the said trap acts as an effective seal against the egress or back passage
of sewer gases. The body of the trap is also more readily set by the confirmation
of its base.
Although I will only now describe my invention as applied to a stench trap, yet
my said invention is equally applicable to drain, gulley and other like traps suffs
and gratings.

The body or casing of the trap consists of a rectangular box open at top or at its
upper end; the base is made preferably flat, in order that the trap may be more
readily set or affixed in connecting it with a drain or other outlet. The body of
the trap when fixed is not liable to rock or move after having once been set, in
consequence of the confirmation of its base. The outlet of the drain trap is
situated on one of its sides, the outlet of which is provided with the usual
depending web or partition extending below the level of the outlet passage for
sealing the trap. And within the rectangular box or casing described I suspend
or hang a loose sediment receptacle that is, a detachable chamber tapering towards
its bottom, which intercepts or collects any dirt or other foreign matters held in
suspension by the water passing through the trap. The chamber is provided near.
its top with outlet water passages, which are somewhat below the grating, covering
the open top of the trap.
The dirt receptacle is provided with finger holes on its side for removing it from
the trap.
The working of the trap is as follows water combined with dirt and other
matters pass through the grating of the trap falls into the suspended chamber or
receptacle, the dirt held in suspension falls to the bottom of the chamber, while the
water alone passes off through the slits or openings near the top of the sides thereof
and falls into the body of the trap, and then passing away through the sealed
outlet as previously described. The dirt or other sediment thus intercepted, can be
removed by withdrawing the suspended chamber and cleansed by turning out the
dirt, and then again replaced in position in the trap.
Having described the nature of my invention, I will proceed to describe with
reference to the accompanying Drawing, the manner in which the same is to be
performed.
Figure 1 is a transverse vertical section shewing a trench or drain trap con-
structed according to my invention-Figure 2 is a plan of the same. with the
grating removed Figure 3 is a plan of the trap with the grating—Figure 4 is the

page_text: casing of the trap separately showing clearly the web or partition for sealing
the trap Figure 5 is the dirt chamber or receptacle separately-Figure 6 is a
vertical section of the same.
The same letters of reference indicate the same parts in the several figures of the
Drawing.
a is the body or casing of the trap, consisting of a rectángular box open at top
or at its upper end-The base is made preferably flat and marked a' in order that
the trap may be more readily set or affixed in connecting it to a drain or other
outlet; so that the body of the trap when fixed, is not liable to rock in consequence
of the square or flat bottom as is the outlet leading to the drain, and a' is the
depending web or partition extending below the level of the outlet passage for
sealing the trap-b is a sediment receptacle, suspended within the rectangular box
or casing a; that is, the receptacle b forms a detachable chamber which intercepts
or collects any dirt or foreign matters precipitated from the waters passing there-
through The said loose chamber is provided near its top with outlet water
passages 63, 62 which are somewhat below the grating c covering the top of the
trap 63, 63 are finger holes, for removing the dirt receptacle b when dirt is required
to be removed-a³ are ledges or rabates, on or into which the flanges 6 of the
receptacle 6 drops, for keeping it in position.
b
The working of the trap is as follows-
Water combined with dirt and other matters pass through the holes in the
grating of the trap into the receptacle 6-the dirt held in suspension falls to the
bottom of the chamber while the water passes off through the slits or openings b²
into the body of the trap and from thence through the outlet a³, which is sealed as
previously described; the dirt or other sediment thus intercepted can be removed
by withdrawing the sediment chamber, which is cleansed by turning out the dirt,
and then again replaced in position for use.
Although I have only represented my invention as applied to a stench trap,
I wish it to be understood that my invention is equally applicable to drain, gulley
and other like traps and gratings of various constructions.
:
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
First The removable and suspended chamber or receptacle for intercepting or
collecting dirt or other sediment passing through the stench or other trap as
described and illustrated.
Secondly The construction of stench, gulley and other traps having a suspended
and movable chamber or dirt réceptacle as described and set forth in the several
figures of the Drawing.
