Abstract

A pallet conveyor has spaced pinion drives which engage racks mounted on the pallets to move the pallets along the conveyor.

Claims

1. A conveyor comprising, in combination:

a longitudinally extending pallet;

a pair of transversely spaced parallel and longitudinally extending ways for supporting said pallet as it is being conveyed along said ways;

a plurality of rotary drive means longitudinally spaced along said ways for engaging and moving said pallet along said ways, each of said plurality of rotary drive means including a driven pinion which engages a longitudinally extending rack on said pallet;

wherein said drive means are spaced from each other a distance so that a downstream drive means engages said pallet before an upstream drive means disengages said pallet; and

wherein said rack is spring loaded to said pallet so that as the pinion of said downstream rotary drive means engages said rack while said pallet is being moved by said upstream rotary drive means, the rack can be displaced relative to said pallet to accommodate the engagement.
