page_text: I, WILLIAM SYKES, 18, New Bridge Street, in the County of London, Civil.
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to trough's to contain electric light cables to be laid
on the solid system. The solid system is laid by providing a suitable trough to
receive the cable, after the cable is laid the trough is filled solid with bitumen
and the top is protected by a suitable cover sufficiently strong to resist the
heavy traffic.

I therefore form my trough (which is preferably made in stoneware) with a
semi circular bottom with vertical sides; about two thirds from the bottom of
the trough I form a ledge or socket running longitudinally the whole length of
the trough this socket may be of any suitable depth and is intended as a recep-
tacle for an in situ" cover composed of Portland cement & sand in suitable
proportions; or other suitable material; after the cable has been laid in the
trough and filled solid with bitumen to the underside of the beforementioned
ledge or socket the remaining portion or the socket is filled with the "in situ"
top of Portland cement and sand which after a short time will set & become a
hard solid mass.
The respective lengths of troughing are connected together by means of
spigot and socket ends and the alignment of the invert is secured by forming
a stoneware stud in the socket of each length so as to prevent the spigot and
dropping below the corresponding length of troughing.

I, WILLIAM SYKES, of 18, New Bridge Street, Blackfriars, in the County of
London, Civil 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:-
This invention relates to troughs to contain electric light or other cables,
to be laid on the solid system, and is preferably made in stoneware. The solid
system is laid by providing a suitable trough to receive the cable after the
cable is laid, the trough is filled solid with bitumen and the top is protected
by a suitable cover sufficiently strong to resist the heavy traffic.

page_text: In order that the nature of this invention may be clearly understood I will
proceed to explain the same by the aid of the accompanying drawings.,
Fig. 1 shows a cross section of my trough, and Fig. 2 shows a longitudinal
section of the same, whereas Fig. 3, shows a modification of my trough to apply
to cases where more than one trough is required in this case three trough's are
required. I do not limit myself to any number of ways or ducts, and my troughs
may be made in multiple form. Fig. 1 shows a cross section of my trough
which is formed with a semi circular bottom (1) and with vertical sides (2) I
form a longitudinal socket (3) with a ledge (4) running the whole length of the
trough. This socket may be of any suitable depth and is intended as a recep-
tacle for an "in situ" cover composed of cement and sand in equal parts mixed
together to form mortar. After the cable (5) has been laid and the trough filled
solid with bitumen (6) to the underside of the socket (4) the socket (3) is filled
with cement mortar which in a short time will set hard and form a hard and
suitable cover. I do not limit myself to this form of cover, suitable bricks may
advantageously be inserted in the socket to form the cover and secured by
pouring in hot bitumen.
Fig. 2 shows a longitudinal section of my trough showing the respective
lengths of troughing attached to each other, as will be seen (7) is a socket ex-
tending round the trough and (8) is a spigot and the two ends are securely
attached by pouring in the cavity (9) bitumen or other suitable material. A
ledge (10) is formed in the socket (7) but extending only about one third round
the invert this ledge will prevent the spigot (8) from dropping below the corre-
sponding trough it will therefore secure the true alignment of the invert.
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. A stoneware trough with spigot and socket ends, a circular base, formed
with a longitudinal socket and ledge to receive suitable cover.
Dated this 6th day of June 1900.
