page_text: I WILLIAM REDDALL of 10 South Street Finsbury in the City of London
Architect do hereby declare the nature of this invention to be as follows:—
The material of which the curb is to be constructed is cast iron.
The curb is in form a box with open ends and provides a receptacle for any
number of wires in proportion to its size. It is open at the top throughout to
admit of any length of wires being inserted or removed or examined.
The curb has a circular perforated bottom for drainage which may be part of the
casting or may be of gutta percha or other flexible material which may be pressed
or sprung into the form and being of greater width than the inside of the curb it
will then impinge upon and become fastened into or against a rebate or fillet
provided for same and when pressed downwards will rest upon the iron flanges or
diaphragms provided for same and can again by pressure be readily removed.
The curb is provided with a drainage cavity below the circular perforated
bottom.
The curb is covered by a cast iron top or cover which is roughened with pointed
corrugations separated into small pyramids with small square channels all round
thus giving a sure foothold. This cover at the back edge fits into a bevilled or á
rebated groove formed in the back of the curb and on the front edge it has a bold
nosing and a fillet forming a groove and it falls down on the front of the curb thus
making the cover immoveable in ordinary use and for further security it can be
easily fastened by means of screws. Any selected length may have the nosing
fitted with pin and socket forming a hinge to open the length of cover at will.
The back of the curb is formed with apertures to admit of the passing out of wires
to supply the houses and shops and it has also apertures at front and back
communicating with the space for drainage.
The uniform fixing of the separate lengths of the curb may be obtained by
making the back and the front one inch shorter and longer respectively than the
top or cover so that the top of one length rests on the front and back of the other
length and the whole is bedded on concrete in the usual manner of curbs.
The casting of the box may be as required either in two pieces the bottom plate
being separate from the box-or it may be in two halves divided vertically in its
centre of the width and it may be put together in an ordinary manner with screws
and lugs but any putting together may be avoided and the pieces may be fixed or
set in their position.

page_text: The construction admits of some variation, thus the perforated bottom a¹ may
either as the drawing shows form part of the casting a or it may be of gutta percha
or other flexible material which may be pressed or sprung into the form and being
of greater width than the inside of the curb will then impinge upon and become
fastened into or against a rebate or fillet provided for the same and when pressed
downwards will rest upon the iron flanges or diaphragms provided for the 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:-
My new or improved street curb substantially as herein described and shown.
