Abstract
An indexing machine includes a continuous chain having a run extending between a pair of movable sprocket gears. Work carriers are provided at spaced intervals along the chain and a plurality of fixed work stations are located at equal intervals along the chain run. The machine includes a drive for continuously moving the chain including a compound worm gear with a lead and a variable pitch diameter. The gear engages followers attached to a sprocket gear so that rotation of the gear simultaneously translates the chain and rotates the sprocket gear to move the work carriers past the work stations and dwell the carriers at the stations.
