COMPLETE SPECIFICATION.
Improvements in Drain Gratings and the like.
I, WILLIAM ROBSON HINDMARSI, Junior, of Bondgate, Alnwick, in the County
of Northumberland, Architect, 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 improvements in drain-gratings and the like, and has
for its object to provide a channelled grating which by offering no obstruction to
the passage of water, will enable such water to readily find its way through the
grating into the drain or the like.
In order that this my said invention may be the more readily understood and
carried into practical enect, reference is hereby made to the accompanying sheet
of illustrative drawings, wherein :-
Fig. 1, is a sectional elevation of a grating in accordance with my invention.
Fig. 2, a section through line A-B of Fig. 1.
Fig. 3, is a plan view, and Figs. 4 and 5, perspective views of two different forms
of the improved grating.
Referring to the drawings, wherein like letters of reference indicate corre-
sponding parts throughout the several figures, a represents the walls or sides
of the grating, which walis or sides are formed of glazed earthenware in the
usual manner.
In order to allow of the water having a free access to the drain through the
metal grating proper b, one or more of the said walls or sides are recessed or
concaved on their upper sides as at a¹, in order to form channels for the ready
admission of the water to the said grating.
The metal bars forming the gratings proper bare so arranged as to conform to
the shapes of the earthenware sides or walls, in which they are fitted.
The said grating bars & are fitted into the earthenware portion of the grating a
either in a parallel direction with the course of the channels, or obliquely, or at
any desired angle thereto.
The necks or stems c of the gratings are made to fit into the different sizes of
drain pipes, the connection being made in the usual manner.
In fitting the improved gratings to drain pipes, the channelled sides of the
said gratings are located so as to face the water-ways, the surfaces of such
channelled sides being approximately level with the surfaces of such water-ways.
These gratings moreover may be made with or without a trap attached.
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 :-
1. The improvements in drain-gratings and the like, consisting in recessing the
upper faces of the earthenwared sides of the grating in such a way as to form
channels, the metal bars forming the grating proper being so fitted in the earthen-
ware sides, as to conform to the shape of the channels therein, substantially as
described and shewn.

page_text: 2. In drain-gratings and the like, the combination of the earthenware sides a
having their upper surfaces recessed to form channels a¹; with the metal bars
or gratings proper b, fitted into said earthenware sides, so that their upper
surfaces conform to the curve of the recesses in said sides, substantially as and
for the purpose hereinbefore described, and as illustrated by the drawings.
Dated this 11th day of October 1899.
