Abstract

A device for feeding pieces of lumber, one by one, from one location to another location and comprising a plurality of carrier members secured in substantially parallel relation along the length of a frame which bridges between an input location and a delivery location. Each of the carrier members are formed to define a downwardy inclined slope having a stop at the lower end thereof. The upper end of the slope is adapted to receive lumber from the input. An elongate shaft is journaled through the carrier members. A clinch member is rotatably journaled on said shaft and located adjacent each of the carrier members. A stopping arm is provided disposed between each carrier member and adjacent clinch. A pivot pin is attached to each carrier member and a guide pin is carried by each clinch, the stopping arm is rotatably journaled on the pivot pin, one end of the stopping arm being movably engaged with the guide pin and the other end carrying a stop formation. The stopping arm is movable relative to the clinch between one position where the stop formation is above the adjacent slope and a second position where the stop formation is below the adjacent slope depending upon the position of …
