Abstract
A sawmill apparatus includes first and second carriages for supporting first and second logging dogs therebeneath, with the second carriage being movable upon the first whereby to engage the ends of a log between the dogs. The carriages support the dogs at the end of steel blades which are moved in a vertical direction by a combination of air cylinders and ball screws to provide accurate positioning of the log at a predetermined distance above a lower saw guide and at a predetermined distance above an outfeed conveyor. Side braces are mounted on each carriage and extend downwardly on each side of the blades carrying the log engaging dogs, the side braces supporting bearing members disposed in slidable relation to the blades for maintaining alignment thereof in the direction of carriage movement.
