Abstract

317,953. British Ropeway Engineering Co., Ltd., and Shields, H. F. H. July 5, 1928. Elevated railways; systems.-To facilitate the transfer of ropeway buckets from their carriers on shunt rails at a loading station to trucks running on ground tracks to and from a loading point, as in a clay-pit or stone quarry, the ground track 14 crosses the shunt rail 11 once only at a transfer point 16 where the buckets are near ground level, and any point such as 16' where the ground track crosses the ropeway is situated where the ropeway is high enough to permit continuous traffic on both levels. As shown, the shunt rail 11 is in the form of a J, but in a modification it forms a U crossed by the ground track at a point such as 16<a>. The hauling rope 13 at the transfer point may drive mechanism for raising and lowering the carriers. This mechanism comprises a pulley 40, Fig. 6, and gearing 39, 37 for rotating a crank-disc 35 which operates a connecting rod 34 and rocking frame 32 carrying a movable section 31 of the shunt rail. The disc 35 is driven through a friction clutch controlled by a hand-line 41 connected to a lever 42. A catch 45 on the lever engages in turn in three notches in the disc so that the mechanism, stops successively in three positions, viz. with the rail section 31 above the level of the shunt rail 11 to prevent a hanger running on to the movable section, with the section 31 level with the shunt rail, and with the section 31 lowered until the hanger is disengaged from the trunnions of a bucket resting on a truck on the ground track.
