Improvements in Supporting and Securing Overhead Flexible
Metal Roads, Especially Applicable to Telpherage Systems.
CHARLES SPENCER EATON CRAKANTHORP Mechanical Engineer Winchester House
London E.C. do hereby declare the nature of this invention to be as follows:-
It relates to overhead stationary flexible lines supported on posts or other suitable
erections and the methods of attaching the said road to the posts or supports.
In these systems of transport the road may be, wire cable or solid rod of any
approved section (but in this specification it will be spoken of as cable).
The special feature of this Invention is a simple and efficient means of securing the
cable on the supports-this is done as follows
-
A casting in the form of a sector and having a groove along the upper and curved
edge is used for receiving the cable, after the cable is placed in position a bridge or
cap is secured and tightened down on to the cable by two bolts, one on each side,
this bridge is tapered away at the ends to a point which lies on the cable and forms
a smooth road for the grooved wheels of the carriages to pass over the supports.
In order to obtain a grip of the cable there is a slight vertical deviation from the
straight line in the groove of the sector, so that when the bridge or cap is tightened
down the cable is forced into the depression thus inade, this is necessary, to prevent
any slipping of the cable through the sector which might occur during the passage of
a train or load.

page_text: To ensure the sector keeping in line with the cable, a spigot or pin is cast on the
under side which fits into a suitable recess in the end of the support this allows the
to swing freely and follow the direction of the cable. In case of adjustment to
the cable being required the bridge can be slacked the adjustment made, and the
bridge or cap tightened down again.

CLAIMS.
I claim the form of support and attachment hereinbefore desbribed in connection
with Telpher lines in which the road is formed of Electrically continuous wire rope or
metal rod.

1, CHARLES SPENCER EATON CRAKANTHORP Engineer, The Telpherage Co. Limited,
50 Old Broad Street London E.C. 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 is an Improvement on Telpherage and refers to the systems of
Telpherage in which an electrically continuous road of wire rope or cable is used.
The special feature of this Invention is a simple and efficient means of securing the
wire rope or cable to the supports which is done as follows :-
A casting A in the form shewn in the drawing and having a groove along the
upper and curved edge is used for receiving the wire rope or cable. A cap or
clamp B is then tightened down on to the wire rope or cable by two bolts C. C. one
on each side. The ends D D of the cap or clamp are tapered away to points which lie
on the wire rope or cable, and form a smooth road over the casting A for the wheels
of the vehicles.
To ensure the casting A and cap or clamp B keeping in line with the cable when
any twisting strain occurs through the shifting of the supports or swinging of the
cable a spigot or pin E is cast on the underside of the casting A to fit into a suitable
recess in the end of the support allowing the whole arrangement of casting A and cap
or clamp B to swivel freely and follow the direction of the pull of the cable. In case
of adjustment to the cable being required the cap or clamp B can be slacked by means
of the bolts C. C, the necessary adjustment made, and the cap or clamp B then
tightened down again by the bolts C. Č.
To illustrate my Invention I have attached to this specification drawings of the
method of attaching wire ropes or cables for Telpherage purposes which I desire to
protect. Fig. I shewing a side elevation and Fig. 2, a section by a plane at right angles
to the axis of the wire rope or cable,

page_text: 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,
1st. The form of attachments hereinbefore described in connection with Telpher and
other systems of aerial flexible lines in which the road is formed of electrically
continuous wire ropes or cables.
2nd. The system of attaching wire ropes or cables to supports as figured and
described.
