1299605 Endless chain conveyers DOUGLASROWNSON Ltd 19 Nov 1970 [25 Nov 1969] 57667/69 Heading B8A A slat type conveyer, Fig. 1, from which articles may be discharged at two lateral positions comprises slats 1 connected to two endless chains 3 to which slat supports 2 are also connected, each slat having a member 6 which slides in tracks (45), Fig. 4 (not shown), mounted beneath the supports 2. The tracks are in two main parallel sets 11, 12 connected by parallel sets 18, 30, the set 11 having a switching device 15 during whose operation a required number of slats are moved along the track 13 to the track 12 from which articles resting thereon are removed by means of a plough blade 23 and during the non-operation of the device 15 the other slats continue movement along the set 11 and along the set 30 to recombine with the slats diverted by the device 15 and pass beneath a second article removing plough blade 23, the recombined slats then moving along a return track 35 back to the left in Fig. 1. The switch 15 comprises a rotatable member (51), Figs. 3 (not shown), operable by means of a solenoid (55) to direct the slat control members 6 in the direction of the arrows (65), (67), Fig. 6 (not shown), into the track 13. The conveyer may incorporate more than one switching device and the number of slats required for direction by the switching device 15 may be calculated by photo-electric cells which measure the length of the article or articles.
