ABSTRACT:
An all purpose indexing device primarily for interrupting the motion of baking pans on a continuously moving conveyor, the baking pans having spaced indentations therein, comprising a U-shaped index bar pivotally mounted to fixed portion of the conveyor frame having a central crosspiece disposed across the conveyor, at least two indexing fingers extending downwardly from the crosspiece toward the conveyor and engagable with the indentations of a baking pan. Air cylinders are connected between the U-shaped index bar and the fixed portion of the conveyor frame at points adjacent respective lateral ends of the index bar. A sensing rod is pivotally mounted to the conveyor frame and disposed parallel to the index bar. A sensing finger is connected adjacent the middle of the sensing rod and extends downwardly towards the conveyor. A microswitch activating cam is connected to one end of the sensing rod and functions to activate the microswitch when the sensing finger is rotated away from the conveyor due to the action of a passing baking pan. An adjustable means is connected between the respective air cylinders and a fixed portion of the frame to allow for adjusting the spacing between the indexing fingers and the conveyor.
