An Improved Gulley and Stench Trap for Waste Water.
I, WILLIAM BOYDELL, of Brown Street Ironworks, Leigh, in the County of
Lancaster, Ironfoun ler, 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 gulleys and traps into which waste water from houses
or other places is received and conveyed into the drains. The objects of my
invention are to prevent solid substances which may incautiously or accidentally
enter either the waste water pipe or other outlet or conduit from choking the
drain pipe, and to afford a ready means for removing said solid substances. I
effect these objects by the means hereinafter described reference being made to the
accompanying sheet of drawings illustrating my invention, in which Fig. 1 is
a transverse sectional view and Fig. 2 a plan of my improved gulley and trap
constructed according to this invention. Fig. 3 is a transverse sectional view of
a modification of the same. In these drawings similar letters refer to similar
parts. In this invention I construct a gulley and trap in the form shown in the
drawings of such material as is usually employed for like purposes.
a is a pro-
jecting tube or pine for forming a connection with the end of the waste water or
other pipe or conduit: b is a chamber for the reception of the waste water before
passing to the drain.: d and dare baffles, the lower ends of which are always below
the level of the water that is retained in the aforesaid chamber b: the connection
with the inlet for the waste water into the chamber may be either as shown in
Fig. 1 or Fig. 3, or of other like form. The waste water enters the receiver by
means of the connection a in which the end of any waste water pipe or conduit is
inserted: the lower edges of the baffles & and are below the line of the lowest
level of the outlet e to the drain: said outlet to drain is separated from the inlet
or waste water pipe by the space forming the receiver b which may be covered by
a lid as e said lid may be either plain or perforated. The waste water
entering through the connection a from any waste water pipe or conduit as g
flows into the receiver which always retains a certain quantity of said waste
water. The level of the waste water thus retained is above the lower edges of
the baffles d and d which are formed so as to be below the line of the lowest
level of the water flowing through the outlet e to the drain. By these means the
escape of sewer gas into any pipe having internal connection with a house is
prevented, and if any solid substance should inadvertently be passed through the
waste water pipe g or other conduit, access can readily be obtained through the
cover e for the removal of said solid substance which would be retained in
the receiver b.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1st. A gulley and trap that is constructed as shown in Figs. 1 and 2 on the
drawing with an inlet from waste water nine or condwit

page_text: as band an outlet to drain that is separate therefrom or on the opposite side of
said chamber, the inlet and outlet being formed by baffles as d and d¹ that are
constantly beneath the surface of a proportion of the waste water that is always
retained in said gulley and accessible by means of a cover as e all substantially
as and for the purpose herein before described.
2nd. A gulley and trap that is constructed as shown in Fig. 3 with an inlet from
waste water pipe or conduit on one side of a chamber as band an outlet to drain
that is separate therefrom or on the opposite side of said chamber, both the inlet
and the outlet being secured against the return of sewer gas by a proportion of
waste water that is always retained in said gulley covering the apertures to the
aforesaid inlet and outlet, all substantially as and for the purpose herein before
described.
3rd. A Gulley and Stench trap that is constructed substantially as and for the
purpose herein before described.
