Plate 22 is rigidly connected to the wheel 20 and plate 24 is carried by a coupling shaft 25 which is slidable in brackets 26, 27 attached to the underside of the surface 19, the shaft 25 being biased into the engaged position of the clutch plates 22 and 24 (as shown in Fig. 3) by a compression spring 28. A clutch operating device comprises a lever 29, pivoted to the shaft 25 at 31 and to the supporting surface 19 at 30, movement of which lever (to the right in Fig. 3) disengages the clutch plates 22 and 24 (thus stopping drive of the carriage by allowing the drivers wheel 20 to rotate freely) and then retards the carriage by contact of one end of shaft 25 with the side of a track wheel 17. While the driven wheel 20 is between two successive drive chains 12, as shown in Fig. 6, second driven means comprising a locked wheel 32 or hook (33), Fig. 6a (not shown), are brought into engagement with a chain 12 by an operating device 36 in the path of the carriage, so that drive of the carriage is maintained. Alternative coupling means to the plates 22, 24 are a cup (41), Fig. 8 (not shown), having an internal tapering surface (42) for engagement by a frusto-conical disc (43), or a conical roller (44), Fig. 9 (not shown), engageable on its periphery by a coupling block (45). As shown in Fig. 10, impulse means on the carriage underside comprise a centrally pivoted means to a non-propelling condition (i.e. clutch plates 22 and 24 disengaged) by causing a coupling rod 57 to move. Pivoted at 64 to the ends of lever 54 are impulse rods 55 protruding beyond the front and rear of the carriages so that the impulse means are actuated when one carriage catches up with another. The surfaces 63 at the carriage underside may contact the rollers of a rollerway, Fig. 11 (not shown), to move the carriage transversely from the track 10, 11. Guide wheels 18, Fig. 3, rotating about vertical axes are mounted at both sides of the carriage to contact the track 10, 11.
