Abstract
A longitudinal lumber conveyor is provided with an adjustable end stop for cutting a piece of lumber into several pieces. The adjustable end stop is mounted on a slide which is adjustable hydraulically beneath the plane of the conveyor. The slide is operable between adjustable end switches which are activated to indicate the desired position of the slide. The slide may be moved between the various end positions when a photocell device mounted on the slide senses that a piece of lumber is not present at the photocell device. The slide has rotatable stop arms mounted on a shaft of the slide which are hydraulically rotatable from a first stop position above the plane of the conveyor to a second position below the plane.
