COMPLETE SPECIFICATION.
Improvements in the Method of and Means for Dealing with Surface
Water from Roads and Pavements.
1, WILLIAM HENRY SLADDIN of Garden Road, Brighouse in the County of
York, Woollen Merchant, 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 :--
The object of my invention is to filter the surface water, so that all refuse
and floating matter is effectually prevented from entering the gulley, sewer, or
drain, by means of grates or iron curbs provided with a series of grids or sieves
graduated or finer towards the gulley, so that the coarser material is collected by
the first grid, then the finer at each successive grid towards the gulley.
DESCRIPTION OF DRAWINGS.
Fig. 1. shows elevation partly in section of my invention.
Fig. 2. is a plan of Fig. 1.
Fig. 3. is a cross section of grid box.
Fig. 4. is a cross section of ordinary box.
I employ a hollow iron box A, with suitable outlet B to the gulley or sewer, the
said hollow box being preferably placed over the gulley or sewer, and has therein a
fine sieve or grid C across or near its outlet, the said hollow box forms preferably
the curb to the pavement or promenade.
At each end of the said box A, are a series of grids or sieves D, the apertures
in which widen successively in each grid as they are further away from the box or
gulley.
Also one of the sides of the box is formed or composed of grids E.
Continuing in lengths at each end of the said hollow box are a series of hollow
boxes or castings A, with side grids E' whose apertures are wider than the grids
in the central box, all the said boxes or castings are provided with loose covers F,
which are taken off when required, for clearing the grids.
When the top or surface water enters the side grids E', (which are widest) it
passes forwards through the graduated grids D in or attached to the central box.
The said central box is so arranged that at each successive grid D, there is an
incline or step F, so that the velocity of the water increases at each grid as it
nears the centre or final sieve or grid, and enters the gulley in a comparatively
filtered state.
The aforesaid boxes and grids may be made of fireclay, or of any suitable metal
or material.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The method of and means for dealing with top water by means of hollow
castings with loose covers, and a series of graduated grids for filtering the water
before it enters the gulley, substantially as shown and described.
2. The construction of hollow boxes forming the curb, with their covers, grids,

3. Constructing the bars of the grids of a narrow fish shape, tapering from the
centre to both sides, substantially as shown and described.
