Abstract
A tree slasher in which the entire trunk of a tree may be simultaneously cut into a plurality of selected lengths to meet subsequent processing requirements. The slasher, while large, is mobile and may, if desired, be taken to the vicinity of the tree-cutting areas thereby to minimize the distances the tree trunks must be hauled prior to cutting.
Claims15
A tree slasher comprising s supporting frame, a transversely upwardly sloping surface carried by said frame and whose long dimension is more or less as long as the tree to be cut,
- said surface being interrupted at selected intervals with pairs of spaced tracks in each of which resides a continuous conveyor chain with the remaining portion of each said chain running beneath said sloping surface,
- a plurality of spaced dogs on each said chain, all said dogs being longitudinally aligned with the dogs on the other said chains,
- a first hydraulic motor and other means for driving all said chains at the same speed along said tracks,
- a chain saw located between each said pair of spaced tracks and an individual hydraulic motor for driving each said chain saw,
- a hydraulic cylinder and piston and other associated means for moving the cutting part of each said chain saw from a cutting position above said sloping surface to a non-cutting position below said sloping surface,
- a prime mover mounted on said frame,
- hydraulic pumps driven by said prime mover, oil tanks supplying said pumps,
- hydraulic pipe lines running from one of said pumps to said first hydraulic motor which drives said conveyor chains,
- other hydraulic pipe lines running from other pumps to said individual hydraulic motors which drive said chain saws,
- other hydraulic pipe lines running from one of said pumps to said hydraulic cylinders and pistons which control the positions of said chain saws,
- manually operable means for controlling the operation of said first hydraulic motor that drives said conveyor chains,
- and manually operable means for actuating selectively each hydraulic cylinder and piston for positioning each said saw.

A tree slasher comprising a main frame having a transversely sloping surface, said surface long enough to accept the tree trunk to be cut,
- a plurality of pairs of spaced conveyor chains with dogs thereon moveable upwardly across said sloping surface whereby a tree trunk may be moved upwardly,
- a remotely controlled motor for driving said conveyor chains,
- a plurality of chain saws each pivotally mounted below said surface and between each pair of conveyor chains,
- remotely controlled means for selectively moving each said chain saw on its said pivot from a position below said surface to a position above said surface,
- and means for collecting chips produced by said chain saws in cutting said tree trunk and for delivering said chips to single location.
2 more elements
A tree slasher comprising a supporting frame,
- a transversely extending surface carried by said frame and across which a tree trunk is to be moved as it is being cut into selected lengths,
- said surface being interrupted at selected intervals with transversely extending pairs of spaced conveyor chains with aligned dogs thereon,
- a motor and other related means for driving all said chains and dogs at the same speed whereby a tree trunk may be moved by said dogs across said surface,
- a plurality of chain saws mounted on pivots below said surface and each saw positioned between each said pair of conveyor chains,
- an individual motor for driving each said chain saw,
- means for causing each said chain saw to turn on its said pivot whereby each said chain saw can be individually moved from a position below said conveyor chains where it will not engage a tree trunk passing thereover to a position above said conveyor chains where it will cut a tree trunk moved there against by said dogs,
- individual housings beneath said surface, each housing enclosing the lower end of each said chain saw when said saw is in up cutting position whereby chips created by said saw will be caught in said housing and suction means for removing said chips from said housing.
