ABSTRACT:
Apparatus is provided having a series of aligned swinging stops to simplify the operation of cutting unwanted end portions off lumber which moves generally sideways through the apparatus. The swinging stops can be used individually to locate an end of the lumber before cutting the lumber. Also any particular stop can swing out of the path of the lumber if the lumber is engaged against another stop. Each swinging stop has a first portion extending generally downwardly from a pivotal mounting for arcuate movement along a path aligned with the direction of travel of the lumber through the apparatus, and a second portion pivotally connected to the first portion below the pivotal mounting for movement in another arcuate path which is also aligned with the direction of travel of the lumber. The second portion has a distal end which is engaged by the lumber when the swinging stop is to move out of the path of the lumber and tends to return to its original position quickly for engagement by a succeeding length of lumber.
