Improvements in and relating to Pavements and Conduits or the like
in connection therewith..
I, HENRY COOMBS, of 576, Woolwich Road, Charlton, S.E., Sanitary Engineer,
do hereby declare the nature of this invention to be as follows:-
-
This invention relates to an improved method for paving, curbing, channelling
or conduit ways and the like, which I propose to construct in the following
manner, viz:-
In the first instance instead of employing the ordinary form of granite curbing
as now so commonly used I propose to adopt and use in place thereof curbing
in hollow or sectional form and lengths, constructed of either iron or steel or of
other suitable material, each end of which would be so constructed as to receive
and permit each length to be securely socketed and fitted therein together
throughout and capable whenever required of being easily detachable whenever
needed. An inspection cover or lid may be provided at occasional lengths on
the upper portion of the receptacle or conduit.
Within the inner portion of the footway or pavement I also propose to pro-
vide a like hollow sectional form of receptacle or channel way constructed of
iron, steel (or other suitable material) in longitudinal parts or lengths, likewise
suitably fitted and provided at their ends, and otherwise, as in manner before
referred to in that of the outer form of hollow curbing, conduit or channel way.
The foot or pathway would be so constructed that at suitable distances apart
in its length, it would be provided with light metal or other frame supports
fitted and suitably secured just at or to the inner side of the metallic (or other
material) hollow curbing or conduit way. And a similar corresponding longi-
tudinal frame support in lengths likewise fitted in position just within or against
the outer portion or side of the channel receptacle, within the inner portion of
the path or footway and by the fore-court of the house or building.
Upon the said longitudinal frame supports, light transverse sectional forms of
metal, steel, iron or other material would be placed at regulated distances apart
and suitably secured thereto and preferably in sectional form as here shewn 1,
or as in an inverted T form, and upon which and against square or other shaped
forms of tiles, bricks, stones, wood, or other suitable substance or material would
readily take or bed against and upon, each square or shape adopted I would pro-
pose to angularly divide same so that each would readily take into their respec-
tive positions and be so securely held. And in case of repair being required, it
could be effected at very small cost and with great rapidity and the footway
always kept in a level position.
As in the first instance of the outer hollow curbway receptacle or conduit
way I give special facilities for receiving within same electric cables, telephone
and other wires or pipes as a direct and available means of communication along
a route.

page_text: In the inner metallic form of receptacle or channel way placed just inside and
under the footway, further facilities are given for bringing and connecting
either gas or water from the mains direct to the house or building and under
control as well as for other purposes.
The method of constructing the pavement or footway would leave ample space
and depth as desired for any purpose.
For short side streets, courts, and alleys requiring suitable coverings or foot-
ways I may adopt a like or lighter plan dispensing with either side receptacles
or conduits which would of course not be required in such cases.
For other covering purposes a similar series of light transverse frames of
inverted T, sectional or like shape of steel or other suitable material would be
employed resting and secured on longitudinal supports so that any covering
material may be inserted or slid into the space afforded for same and within
grooves provided.

Improvements in and relating to Pavements and Conduits or the like
in connection therewith.
I, HENRY COOMBS, of 576, Woolwich Road, Charlton, S.E., Sanitary Engineer,
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 relates to an improved method of, and means for constructing
pavements, comprising conduits, channels, and the like for carrying pipes, elec-
trical conductors, or pneumatic tubes or any system of tubing, and has for its
object the increased facility in laying the paving, and removing any part for
inspection, and further to obviate the expense and inconvenience attending the
stoppage of footways when such pipes or the like have to be searched out by
excavation.
In order that my said invention may be clearly understood, I have appended
the accompanying sheet of drawings, in which Figure 1 is a plan view of the
surface of the pavement. Figure 2 is a sectional view thereof upon the line A B.
Figure 3 is a longitudinal section of a modification of the device, and Figure 4
is a perspective view of part thereof. Figure 5 is a cross sectional view of an
adaptation for pavement or foot-way lights, to be used in connection with or
apart from the improved pavement aforesaid. Figure 6 is a plan view thereof.
Similar letters of reference indicate corresponding parts throughout the several
views.
In carrying my invention into practice I do not employ the ordinary granite
curbing, but substitute therefor a pair of channels C C Figures 1 and 2 which
are preferably made of light metal, such as iron or steel. Said channels are
made in lengths, and are joined together by socket or butt joints, or any equi-
valent device for sealing them, so that in cases of emergency they may be easily
detached. An inspection cover or lid may be provided at intervals along the
hollow channels C C. Between said channels CCI provide an opening D which
may be used for carrying transverse pipes, wires or the like between the channels
aforesaid, which are arranged to act as conduits for carrying longitudinal wires
pipes or the like for any kind of service, holes a being formed in the sides for

the channels CC, at suitable intervals I place light iron or steel bars, m
resting upon, and pinned or rivetted to longitudinal bars b b¹ so as to serve the
purpose of ties as well as to carry the pavement blocks c which are let in with
insertion strips, and grouted with cement or otherwise sealed. Said blocks
may be of artificial stone, brick tiles or wood. I may chamfer the edges of
the paving blocks c so as to more readily take the grouting and provide a secure
footway. In the Figures 1 and 2, d represents the forecourt of a house or build-
ing and e the road way. Therefore, if electric light or telephone leads are
carried through the conduits formed by the hollow channels C C branch leads
may readily be led into such buildings through the holes a. In crossing side
streets the conduits are dipped below the road way by means of angular joints.
A modification shown by Figures 3 and 4 has no channels or conduits C C¹
as in the foregoing example, but the paving blocks care held in place between
1 bars m, pinned or rivetted to lengths of L bars 6 b' which are supported by
metal legs at intervals. Said legs 7 may be bedded in cement, and the pipes,
wires and the like are carried through the hollow space D, and are so fixed
by cementing or the like as to be readily removeable for connecting any kind
of branch to the service or for inspection.
Figures 5 and 6 are respectively sectional elevation and plan of a light frame
work formed of transverse bars 6 supporting H bars m m¹ into which the paving
blocks are inserted as shown. This arrangement is especially applicable to
holding the thick glass blocks for pavement lights.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:-
First. In pavements, the combination of two hollow channels or conduits C C,
with a light metal frame-work consisting of longitudinal bars bb₁ and transverse
bars m holding paving blocks c substantially as and for the purposes hercin set
forth with reference to Figures 1 and 2 of the appended drawings.
Second. In pavements the construction and use of a light frame formed of
bars bb, m and legs . substantially as and for the purposes herein set forth,
and shown by Figures 3 and 4 of the appended drawings.
Third. In pavements, the construction and use of a light frame with H bars,
substantially as and for the purposes herein set forth, with reference to Figures 5
and 6 of the appended drawings.
