ABSTRACT:
An improved fully mechanized sawmill is provided which is composed of structurally independent modules which are removably mounted on a platform composed of a plurality of side-by-side longerons supported horizontally on files of spaced-apart vertical piers and columns. The longerons provide horizontal stress support for the platform along the files of piers and columns perpendicularly to the cutting axis of the sawmill, and the modules mounted thereon provide horizontal stress support for the platform along the ranks of the piers and columns parallel to the cutting axis. In addition, improved mechanisms and techniques are provided for handling and selecting the sawlogs to be cut, for selecting and distributing the pieces cut therefrom according to shape and utility, and for stacking and handling the distributed pieces at preselected locations according to shape and utility. In particular, there is provided at least two hollow slotted pull-off arms containing therein a pneumatic cylinder. Upon extension of the piston rod of the cylinder, a dogging tooth rides within the hollow member. However, upon retraction of the piston rod, the dogging tooth is caused to extend through the slot of the hollow member.
