Abstract
A sawmill for tree logs includes a rocking carriage to pick up fresh logs and feed them into the path of a saw blade, as well further provisions relating to improvements to infeed systems for the fresh logs, as well as to, outflow systems for transfer of sawn-off product to a production line conveyor or the like for further processing to downline processes after the first saw cuts on the fresh logs.
Claims20
A sawmill for logs comprising:
- a bandsaw mounted on a carriage for traversing between left and right extremes;
- a rocking carriage comprising a log bunk which serves as the primary support deck for a log during saw operations;
- said log bunk comprising a spaced plurality of frames collectively defining a plane of the log bunk which is the plane log is supported upon;
- said rocking carriage further comprising plural head assemblies coupled on top of the frames of the log bunk or parallel pairs of the frames of the log bunk to translate over the frames between forward and rearward extremes;
- each head assembly presenting a backstop surface such that the plural backstop surface can be adjusted to be collectively contained in a plane of the backstop surfaces that is generally perpendicular to the plane of the log bunk;
- said rocking carriage being arranged to rock forwardly and rearwardly between clockwise and counterclockwise extremes about a rocking axis;
- if the plane of the log bunk were adjusted to horizontally level, the plane of the log bunk and the plane of the collective backstop surfaces of the head assemblies define essentially a perpendicular L-shaped corner;
- wherein the rocking axis is disposed substantially spaced away under the plane of the log bunk.

A sawmill for logs to saw off elongate pieces, comprising:
- a bandsaw mounted on a carriage for traversing a path between left and right extremes;
- the bandsaw comprising a saw blade which makes saw cuts in a given plane of saw blade cutting travel;
- the bandsaw and carriage being arranged to carry the bandsaw such that the given plane of saw blade cutting travel is tilted rearwardly to a shallow angle from vertical;
- a telescoping downslide comprising a plurality of ribs;
- said ribs being collectively arranged to telescope along a generally left to right axis between expanded open and foreshortened shut extremes, wherein the ribs of said downslide include a furthest-left rib and a furthest-right rib;
- wherein the one the furthest-left rib or furthest-right rib is generally associated with a stationary point proximate one of the left or right extremes of the bandsaw traverse, the other being generally associated with the other of the left or right extremes of the bandsaw traverse;
- said downslide extending from an upper rearward edge to a lower forward edge which are sufficiently spaced apart to safely deliver a sawn-off piece safely out of the way of the traverse pass of the bandsaw and carriage.

A sawmill for logs to saw off elongate pieces, comprising:
- a bandsaw mounted on a carriage for traversing a path between left and right extremes;
- a left-side and right-side telescoping downslide, each comprising a plurality of ribs;
- said ribs of each telescoping downslide being collectively arranged to telescope along a generally left to right axis between expanded open and foreshortened shut extremes, wherein the ribs of each downslide include a furthest-left rib and a furthest-right rib;
- wherein the furthest-left rib of the left-side downslide and the furthest-right rib of the right-side downslide are generally associated with a stationary point proximate the left and right extremes respectively of the handsaw traverse, and, the furthest-right rib of the left-side downslide and the furthest-left rib of the right-side downslide are generally associated with travel with the bandsaw traverse;
- said downslide extending from an upper rearward edge to a lower forward edge which are sufficiently spaced apart to safely deliver a sawn-off piece safely out of the way of the traverse pass of the bandsaw and carriage.
