ABSTRACT:
A saw mill for producing square cross section timber pieces is disclosed. The mill includes a log orientation mechanism having three, spaced independently operable log elevating units. The units include pairs of log supporting discs. The discs of one unit only are power driven to turn the log on its longitudinal axis. A log dogging, indexing and stabilizing mechanism includes a pair of carriage mounted units on an overhead trackway. One such unit carries a log supporting and precision indexing dog which is turned through ninety degrees of rotation between positive stops by a power cylinder. The same unit carries a log stabilizing dog above the indexing dog which is moved axially into and out of engagement with a log end face while being held against rotation by another power cylinder. The log orientation mechanism is compatible with state-of-the-art scanning and microprocessor devices and the log may simply be visually scanned during orientation by an operator of the mill.
