IMPROVEMENTS IN MEANS FOR CARRYING ELECTRIC WIRES THROUGH STREETS'
»
According to my Invention I make a series of hollow blocks of iron, stoneware
or other suitable material or combination of such suitable materials moulded cast
or cut into forms and sections suitable for the double purpose of (1) carrying
electric wires through them and of (2) being used also (A) for the kerbs of foot-
paths of Streets along which it may be desired to lay electric wires or for (B) the
paving of streets across or along the roadway of which it may be desired to lay
electric wires
The blocks (A) suitable for kerbs may be of various widths and depths as in
existing kerbs and either straight or curved so as to carry the wires along the
straight or curved line of the footpath or to avoid lamp posts or other erections on
the footpath and the base of the blocks may be made horizontal or sloping down-
wards so as to carry the wires either horizontal or sloping downwards at the
crossing of streets or elsewhere The blocks (A) are formed with holes or openings
at the side capable of being plugged these holes or openings are for the passage or
branch wires from the blocks and the blocks may be formed with or without
moveable tops so that access may be provided to the wires within. The said
blocks may be formed of cast or wrought iron with or without a lining of pitch
and tar or other insulating substance, their top surface may be roughened to avoid
slipperiness or may be formed of sinall blocks of wood or stone or other less
slippery or conductive material let into the cover of the block
These blocks may be formed of concrete or stoneware or may be lined or
covered with wood concrete or stoneware to assist in the insulation of the wires
and to form an upper surface of a material suitable for foot passengers
The blocks (B) suitable for carrying the wires across or along the roadway are
formed hollow, rectangular or nearly rectangular on the top and sides and
corrugated or roughened on the upper surface the base may be level or inclined to
suit the level or slope required for the wires to be carried across or along the
roadway or at the junction between the roadway and the footpath

page_text: The blocks (B) may also be made so that stone or wood or asphalte or other
insulating or less slippery material may be fitted into the top surface of the
block
The blocks (B) may be formed also with moveable tops fastened down by bolts
or pins or screws or wedges so as to provide access to the wires within
In laying these blocks (B) across or along a roadway a course of Granite or
other stone paving blocks may be laid on each side so as to prevent the shock of
passing vehicles from injuring them and to enable the rest of the roadway to be
kept more easily level with the surface of the blocks
All these blocks above described may be formed at their ends so that they
fasten together or abut against each other so as to form a continuous tube for the
wires contained therein
