in the side view, touches a tripper the point of suspension of the bucket being, as is
usual in such cases, slightly below the centre of gravity, ihe grip or coupling for the
hauling rope is here shown above the
rail rope as is customary in cases where
only gentle inclines are negotiated.
The other receptacles are made to
suit the varying nature of the material.
These small Bleichert couplings for an
upper haulage rope have the advantage
that at the terminals, and when nego-
tiating curves, no shunt rail is necessary
as the clips will pass round the guide
wheels and terminals. With the haul-
age rope below the rail rope this would
not be possible except with an arrange-
ment similar to that shown in Fig. 431.
This diagram shows also a different type
of bucket with its accessories, having four
rollers. Here the clip is so designed that
one portion also carries the pin for the
suspension of the frame for the bucket.
It is frequently expedient to transfer
mining tubs from their rails to a rope-
way in order to place them again on to
rails at some distance away, as this saves
the transferring of the material from the
mining tub to the ropeway bucket, and
at the terminal of the ropeway back
again into tubs; for such purposes of
suspending mine tubs different methods
are employed. The one shown in Fig.
432 consists of one complete carrier with
coupling for the haulage rope, and a
trailer to support the other end of the
tub, the chains with hooks carrying the
tub. For larger installations two carriers
may be employed, or complete frame-
work may be used to receive the tub,
but the last method naturally increases
the weight on the rope considerably.
The ropeway of the Powel Duffryn
Steam Coal Co., for the disposal of spoil
from their pits, is of interest, as the line
has to negotiate several curves. The
capacity is 100 carrier loads per hour.
Fig. 433 shows part of this line, which
is on the Bleichert system.
The Vivero Iron Ore Co., in North-
ern Spain, has installed five ropeways
