摘要： An apparatus which during a continuous repetitive cycle delivers pieces of lumber, one at a time, to a supporting and clamping means. Each lumber piece in succession is shifted laterally during the supporting and clamping step to a work station where it is firmly held. During the shifting to the work station, each lumber piece is properly positioned longitudinally. While at the work station, plural right-angular drilling means and a handleshaping means are simultaneously activated to produce true openings transversely through each lumber piece while one end of the piece is being shaped into a handle. Some of the openings are formed at right angles to other openings. The drilling and shaping means are retracted and each handle is released onto a conveyor means for delivery to a coacting sander for the shaped handle portion.

摘要： To prevent overloading and damage or destruction of the flair shaft bearings and the universal joints of the input drive shaft, the flail chains of the spreader are connected to the shaft in staggered relation along two spiral paths, thus avoiding a concentrated shock loading of the shaft bearings and universal joints when the chain flails engage the solid material.
