IMPROVEMENTS IN STREET GULLEYS AND OTHER LIQUID traps and
Year: 1885

page_text: We HENRY JOHN PEARSON of Beeston in the County of Nottingham Horti-
cultural Builder and GEORGE MORRIS of the same place Pattern Maker do hereby
declare the nature of our invention for "IMPROVEMENTS IN STREET GULLEYS AND
OTHER LIQUID traps and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
33
According to this Invention we construct a street gulley or other trap of a pit
or receptacle near the top of which is a side outlet with a socket around it on the
inside into this the end of a loose tubular bend is inserted and is kept pressed
into the socket by the bend being suspended from an inclined pin or pins projecting
out from the side of the pit above the outlet or by the bend being formed with an
arm projecting from it to rest at its end on an incline on the side of the pit
opposite to the outlet or both these means may be adopted. The joint between
the end of the bend and the socket may be made air tight by an india rubber or
other elastic ring.
A street gulley or other trap constructed as above described gives great depth of
trap and so reduces the risk of the trap becoming unsealed in dry weather-all
deposits of solid matter collected in the pit or gulley can also be readily cleared out
from it as the lower bend can at once be lifted up and removed by a handle
formed on it-the outlet also can readily be cleaned without disturbing the pit or
gulley.
In the Drawings hereunto annexed we have shewn a street gulley trap
constructed as above described.
Figure 1 is a vertical section of the gulley trap and Figure 2 is a plan view with
the top grating removed.
A is the catch pit or gulley, in the drawing it is shewn to be circular in plan
view but it might be square or of other form-B is an iron grating by which the
top of the catch pit or gulley is covered over-the drawing shows this grating as
resting in an iron frame fixed a short distance above the top of the catch pit or
gulley so as to relieve it from the pressure of heavy loads passing along the street-
in this case the catch pit or gulley may be of earthenware or iron or other suitable
material, the pit might however if preferred be formed in the same way as an
ordinary street gulley and the grating be supported by it-C is the outlet from the
pit or gulley. C' is the socket into which the end of the loose bend D enters.
E is an inclined pin projecting out from the side of the pit above the outlet-the
CD

page_text: pin is shown to be formed on a piece bolted on to the inside of the pit but it might
be formed in one piece with the pit itself. F is a loop formed on the top of the
bend and hooking over the pin E. G is an arm extending from the bend and
resting against an incline H standing out from the side of the pit opposite to the
outlet. I is a handle by which the bend may be lifted up and removed. J is an
elastic ring placed within the socket for the end of the bend to rest against.
Other forms of liquid traps may be constructed in a similar manner to that above
described and may be used in sewage and other work.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that
what. we claim is
1. The construction of a street gulley or other trap of a pit or receptacle with a
side outlet near the top having a socket on its inner end into which the end of a
loose tubular bend is pressed either by the bend being suspended from a pin or
pins above the outlet or by an arm projecting from the bend being made to bear
against an incline on the side of the pit opposite to the outlet or by both these
means substantially as described.
2. The construction of a street gulley or other trap substantially as herein before
described and illustrated in the drawing annexed.
