Abstract

A lumber turning device for use with a conveyer having spaced apart lumber moving therealong whereby the lumber may be turned through 180° so that all faces of the lumber may be visually inspected. A first arrangement has a four lobed member whereby a first one of the lobes will extend upwardly above the conveyer with a front surface facing a first lumber piece such that when the locked first lumber piece contacts the front surface of the first one of the lobes, the member will rotate and a rear face of an adjacent lobe will lift the lumber piece to rotate the same through 180°. Other embodiments illustrate members which may turn alternate pieces of lumber.
