IMPROVEMENTS IN CONDUITS FOR THE ROPES OR CABLES OF CABLE RAILWAYS
Year: 1884

page_text: I HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my invention for "IMPROVEMENTS IN CONDUITS FOR THE ROPES OR CABLES
OF CABLE RAILWAYS " 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 conduits for the ropes or cables of cable railways, and
comprises a conduit for a cable railway having its top bars or slot irons hinged to
the side plates whereby access may be readily had to the interior of the said
conduit, and provided with means for sustaining or supporting the said slot irons
when in closed position as will be hereinafter fully set forth.
In the accompanying drawing
Figure 1 is a transverse vertical section of a conduit having hinged slot irons
according to this invention.
Figure 2 is a longitudinal section thereof, and
Figure 3 is a top or plan view.
A A represent the side plates of the section of a conduit.
The top bars, or slot angle irons B, are hinged on their outer sides to the top of
the side plates, suitable ears and pintles being provided to form the hinges of the
plates.
By this provision the irons may be readily raised, thus opening the conduit and
permitting access to the interior thereof for purposes of inspection, repairs, etc, the
irons being afterwards conveniently restored in position, thus closing the conduit,
and leaving the necessary space or passage between the irons for the cable grip.
B¹ B' represent pieces of angle or T-iron which are secured to the side plates of
the conduit near the top thereof, and project horizontally therefrom, whereby, when
the slot irons are in their normal positions closing the conduit, they rest on the said
pieces B and are thereby firmly sustained or supported, said pieces in no wise
interfering with the continuity of the slot or passage of the grip.

page_text: The hinged irons may be applied to each section of the conduit, or at intervals to
sections throughout the length of the conduit.
Depending from the inner or lower faces of the irons B are longitudinally
extending ribs C, which serve to strengthen the irons, adapting them to sustain
the weight of vehicles etc, passing over the same. These ribs are the vertical limbs
of angle or T-iron rivetted or bolted to the irons B, whereby the latter are stiffened
and braced and a strong structure is produced.
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:
First. A conduit for a cable railway having hinged slot irons, and supports for
the same formed of angle or T-iron connected with the side plates of the conduit,
substantially as, and for the purpose, set forth.
Second. In a conduit for a cable railway, the slot irons in combination with
angle or T-irons, the said slot irons being hinged to the side plates of the conduit,
and the said angle or T-irons being connected with the slot irons, substantially, as
and for the purpose, set forth.
Third. A conduit for a cable railway, having hinged slot irons, angle or T-irons
connected with the said slot irons, and supports for the slot irons formed of angle
or T-iron connected with the side plates of the conduit, substantially as, and for
the purpose, set forth.

Fourth. In a conduit for a cable railway, the slot irons hinged to the side plates,
in combination with angle or T-irons connected with the said plates and forming
strengthening ribs for the same, substantially as, and for the purpose, set forth.
