<p>There is described a power and free conveyor that provides a closed track 10, having an upper 12 and lower 13 run, around which carriers 16 can run. An endless driven band 17 of which the path reflects that of the track 10 is provided with outwardly projecting pushers 22 to engage the carriers 16. Engagement is effected by the dogs 23 and 24 which are pivotally mounted on the carrier. Each is balanced about its pivot point that dog 23 hangs down into the path of the pusher 22 when the carrier is on the upper run with the dog 24 lying clear of the pusher, whilst the dog 24 projects up into engagement with the pusher 22 when the carrier is on the lower run, with that dog 23 lying clear of the pusher. The dogs can be pushed out of engagement with the pusher 22 either by the projection 25 from a stationary preceding carrier or with an inserted stop S.</p> |
