Purposes of Flushing.
I, EDWARD ANTHONY of No. 2 Park Villas, Whitestile Road, Brentford in the
County of Middlesex, Clerk of Works, do hereby declare the nature of this invention
to be as follows:-
My invention has for its object the providing for and facilitating the flushing of
sewers and drains.
For this purpose I use the ordinary sewer flap as used for flushing and other
purposes in sewers, and my invention relates to the addition of a bolt made to slide in
a suitable slot or barrel cast on or attached to the flap, and a hole or staple cast on or
attached to the frame of the flap to receive such bolt. When fixed in a Manhole or
Flushing Chamber of a sewer the flap by this arrangement can be securely closed and
the sewage collected above, and by suddenly lifting the bolt from the surface or road
level or any other level by means of a chain or rod which I attach thereto, the
collected sewage is allowed to discharge itself into the drain or sewer.
I prefer the bolt constructed of wrought iron with a suitable projection to allow of
its being more conveniently closed by means of a man's foot.

Purposes of Flushing.
I, EDWARD ANTHONY, of No. 2 Park Villas, Whitestile Road, Brentford, in the
County of Middlesex, Clerk of Works, 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 :-
My Invention has for. its object the providing for, and facilitating the flushing of
sewers, drains or like conduits:
In order that my Invention may be the better understood, I have appended the
accompanying sheet of drawings, in which Figure 1 represents an elevation of a
sewer outlet with flap attached, and having adapted thereto the device according to
my Invention. Figure 2 being a transverse sectional view of same.
In carrying out my Invention I attach to an ordinary sewer flap A hinged at B, B',
a bolt C preferably of wrought iron arranged to slide freely in a suitable slot, barrel
or socket D, which is cast or may be bolted or otherwise attached to the flap A. I
further provide a projection or staple E cast on, bolted or otherwise attached to the
frame F of the flap A, and inclined or curved so as to ensure that the act of closing
the flap A by a man's foot, by means of the projection d, or by simply dropping it
and allowing it to close by gravity, permits the bolt C to be raised by the inclination
or curve of said projection or staple E until the tapered end of said bolt engages with
the hole c formed in E for its reception. A shackle or equivalent a is provided upon
the lower part of the bolt C, so that a chain, rod, or rope may be attached when it is
required to open the flap from the surface, road level or elsewhere. A pin b fitted to
the upper part of the bolt C serving to prevent the latter from falling out of the slot,
barrel or socket D.
Thus according to my Invention, the improved sewer flap when adapted to a
manhole or flushing chamber of a sewer may be securely closed, and the sewage
collected above, and then by suddenly lifting the bolt C, as and by the means above
described, the collected sewage may be discharged when required into the conduit for
passage of same.
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 :-
The adaption to a sewer flap at the outlet of the manhole or the flushing chamber,
of the bolt Cand accessory fittings D, E, a, c and d substantially as and for the
purposes herein set forth.
