Abstract
Coaxial centers for engaging opposite ends of a log sector to turn about the axis through the centers are mounted on a frame below an overhead sawing device movable along a track extending lengthwise of such axis. Such frame is tiltable about an axis extending transversely of the track supporting the sawing device to alter the angular relationship between the axis through the centers and the track guiding the sawing device.
Claims11
Apparatus for making a cant from a log sector, comprising sawing means, overhead track means supporting said sawing means for travel longitudinally of said track means, means supporting said track means for adjustment both elevationally and horizontally transversely of their length, a live center and a dead center engageable with opposite ends, respectively, of a log sector to be cut into a cant by said sawing means, means supporting one of said centers for movement relative to the other of said centers for engaging the opposite ends of the log sector, respectively, by said centers, and means for rotating said live center to present different sides of the log sector to be cut by said sawing means.
A process for making a cant from a log sector which is tapered lengthwise, which comprises supporting the log sector by centers engageable with its opposite ends in proximity to sawing means mounted to travel lengthwise of the log sector, tilting the centers conjointly and the line of travel of the saw means relatively so as to cut a slab from a round portion of the log sector which is of substantially uniform central radial thickness throughout its length, and moving the sawing means lengthwise of the log sector and thereby cutting such slab from the log sector.
A process for making a cant from a log sector which has an apex angle less than 180 degrees, which comprises cutting the apex of the log sector to a predetermined depth into lumber-making blanks and slabbing the round portion of the sector to remove the bark therefrom.
A process for making a cant from a log sector which is tapered lengthwise which comprises supporting the log sector by centers engageable with its opposite ends in proximity to sawing means mounted to travel lengthwise of the log sector, tilting the centers conjointly and the line of travel of the saw means relatively so as to cut a slab from the log sector which is of substantially uniform central radial thickness throughout its length, moving the sawing means lengthwise of the log sector and thereby cutting a slab from a round portion of the log sector, turning the log sector about the axis of the centers and moving the sawing means lengthwise of the log sectors and thereby cutting a further slab from another round portion of the log sector which is of substantially uniform central radial width throughout its length.
A process for making a cant from a log sector which has an apex angle less than 180 degrees which comprises supporting the log sector by centers engageable with its opposite ends in proximity to sawing means mounted to travel lengthwise of the log sector, moving the sawing means lengthwise of the log and thereby cutting a slab from a round portion of the log sector, turning the log sector about the axis of the centers, moving the sawing means lengthwise of the log sector and thereby cutting a further slab from another round portion of the log sector, and turning the log sector about the axis of its supporting centers for disposition of the apex of the log sector to be cut to a predetermined depth into lumber-making blanks by the sawing means.
