PROVISIONAL SPECIFICATION.
Improvements connected with Kerbs, Edging Blocks, Platform
Copings, Flights of Steps, and the like.
I ROBERT FRANCIS TYHURST of Framfield Road, Uckfield Sussex, Builders'
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention has for object certain improvements connected with kerbs, edging
blocks, platform copings, flights of steps and the like.
For the purpose of my invention I cut or mould an extension or lap in the inner
face of a kerb, edging block, platform coping or a stair step with a forwardly sunken
top surface into or from which angle holes, channels or gutter like grooves can be
formed to lead any water percolating through joint seams from deflection of path, flags
or other causes to the front or in other direction as desired.
The extension or lap is of such dimensions that outer flags, bricks, pitching stones
or cubes constituting the path or platform bear on same and leave a space or loose-
ness of fit as to form a passage for water to drain to the outlets.
With stone or concrete steps or the like the lower front portion of each riser would
rest upon extension or lip of the next step or tread below, the water being led to flow
over the lower steps in successive order.
If desired the draining tube channel or groove may be to a conduit common to
many of them.

I ROBERT FRANCIS TYHURST of Framfield Road, Uckfield, Sussex, Builders'
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 :-
This invention has for object certain improvements connected with kerbs, edging
blocks, platform copings, flights of steps and the like.
For the purposes of my invention 1 cut or mould an extension or lap in the inner
face of a kerb, edging block, platform, coping, or a stair step with a forwardly
sunken top surface into or from which angled holes, channels or gutter like grooves
can be formed to lead any water percolating through joint seams from deflection of
path flags or other causes to the front or in other direction as desired.
The extension or lap is of such dimensions that outer flags, bricks, pitching stones

ness of fit as to form a passage for water to drain to outlets for escape.
With stone or concrete steps or the like the lower front portion of each riser would
rest upon extension or lip of the next step or tread below the water being led to
flow over or from the steps in successive order.
If desired the draining tube, channel or groove may be to a conduit common to
many of them.
My invention will be clearly understood by reference to the annexed drawings
Figures 1, 2, 3 and 4 are transverse section of a plain edging block or kerb of
different shapes.
Figures 5, 6, 7 and 8 are general views of parts of paths or platforms with my
invention applied.
Figure 9, section of steps.
Figure 10, transverse section of path kerbing specially adapted for swimming
baths, wharfs, quay sides, and the like.
A, A, are the kerbs, edging blocks, platform copings, steps or the like.
B, B, recessed or reduced back lip or extension lap on which the outer flagstones,
bricks, pitching stones, cubes, slabs, tiles, asphalte, wood, concrete or other paving
material C can rest, the front of such lip or lap being inclined or formed with a
water collecting passage as at D to be in communication with the outlet channel E
for draining the water away from the path.
For copings of the paths of swimming baths, wharfs, quay side, or other very
exposed edging or kerbs as at Figure 10 I purpose having a top channel F also
in communication at intervals with the outlet E for clearing the surface of water
without it flowing over the edge as at present the part between F and the extreme
edge being kept comparatively dry whereby a bather will obtain a better foothold
for diving from or for walking on the edging as desired.
The view, Figure 5, is supposed to be a flagged or slab path G. Figure 6 a tiled
one. Figure 7 of brick or wood. Figure 8 of asphalte. Figure 9 shows a series of
steps set on one another by the lips B and with channels D and outlets E to lead the
back drip water from one to the other downwardly to a path or gutter.
If necessary where the lip is cut or moulded low down at the back of the block
a brick or other bearer may be employed for the outer flag or its equivalent to rest
on as at H Figure 10.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
I claim is :-
The improvements in or connected with kerbs, edging blocks platform copings
flights of stops or the like in conjunction with escape channels as described and
substantially as shown for the purpose set forth, viz. freeing the water percolated
through path joints.
